Highly compressed filter tow bales and process for their production

Disclosed is a packed, highly compressed cuboid-shaped filter tow bale, the top side and bottom side of which are free from noisome curvatures or constructions. The bale is characterized by the fact that (a) the bale has a packing density of at least 300 kg / m3, (b) the bale is entirely wrapped in an elastic packaging material which is provided with one or several convectively airtight connections, and (c) the upper side and lower side of the bale are substantially planar such that a flat plate which fully covers the bale can be pressed onto the upper side of the bale via a centrally effective normal force of 100 N and at least 90 percent of the surface of the upper side of the bale, which lies within the largest rectangle that can be inscribed by vertically projecting the bale onto the pressed plate, has a maximum distance of about 40 mm from the flat plate when the unopened bale is placed on a horizontal plane. A particularly suitable method for producing said bale comprises the following steps: (a) filter tow is supplied in a compressed form; (b) the compressed filter tow is enveloped in a wrapping; (c) the wrapping is closed in an airtight manner; and (d) the wrapped bale is relieved of the load. The wrapping of such a bale is largely prevented from bursting as a result of the prevailing internal pressure. The inventive bale has an ideal cuboid shape such that curvatures negatively affecting the bale during transport, or constructions hampering the behavior of the filter tow, are largely prevented from occurring.

Method of setting the pre-load for a ball socket joint

ActiveUS20070163100A1Clearance sensitiveCompression sensitiveSuspensionsShaftsMechanical engineering
A method for assembling a ball and socket assembly (10) includes loading a housing (14) with a resilient preload washer (28), an inner bearing (30), a ball stud (12) and an outer bearing (36). A loading tool (50) forcefully compresses the assembled components, as a unit, to an overload compression condition (54), and then reduces the compression until an ideal compression condition (56) is achieved. The outer bearing (36) is staked in position while the loading tool (50) holds the assembled components in the ideal compression condition (56). Following the staking operation, the loading tool (50) can be removed, and a final crimping operation permanently sets the outer bearing (36) in position and holds the articulating components in the ideal, pre-load clearance established. The subject method is particularly well-suited for high production set-ups in which precise pre-load clearances must be achieved at high through put rates.

System for integrating mid-range and high-frequency acoustic sources in multi-way loudspeakers

InactiveUS7134523B2Improve acoustic power outputReduce spacingMetal casingsCabinetsIntegratorSound energy
This invention provides a radiation boundary integrator (“RBI”) for integrating sound radiation from mid-range and high-frequency sources in multi-way loudspeakers. The RBI is a substantially solid boundary that is placed over the mid-range speakers to provide smooth, wave-guiding side walls to control the angular radiation of the high-frequency sound waves emanating from the high-frequency sound sources. To allow the mid-range frequency sound waves generated from mid-range sound sources to pass through the RBI, the RBI is designed with openings. To further prevent the possibility of having high-frequency sound radiate through the openings in the RBI, the RBI may be designed with porous material in the openings of the RBI. The porous material would be transparent to the mid-range sound radiation, but would prevent the high-frequency sound radiation from being disturbed by the openings in the RBI. As such, the RBI provides an outer or front surface area that forms an acoustical barrier to high frequencies radiating across the front surface, yet is acoustically transparent to mid-range frequencies radiating through openings in the RBI. The RBI may also serve as a volume displacement device to compression-load the mid-range sound sources by contouring the back side of the RBI to the shape of the mid-range sound sources thus reducing the space between the RBI and the mid-range sound sources and loading the mid-range sound sources to generate greater mid-range sound energy.

The invention is a mantel or shelf made of a solid block of reclaimed wood with a hidden mounting assembly. The mantel has sufficient thickness, depth and length to accommodate an elongated L-shaped sheet metal bracket with planar horizontal and vertical flanges to allow selective lateral positioning of the mantel relative to its securement to spaced vertical wall studs. An L-shaped opening in the rear of the mantel is formed by a deep horizontal slot and a shallow vertical recess extending down from the slot. The slot is parallel to and near the top of the mantel, and receives the horizontal flange. The recess receives the vertical flange so the mantel is flush with the wall. A mounting fastener inserted into the mantel pierces the horizontal flange to capture the bracket and secure the mantel to the wall. The bracket, slot and recess are hidden from view during use.

Method of manufacturing centrifugal pump

A centrifugal blood pump prevents a shaft member from oscillating due to expansion of a pump housing resulting from pressurization of the blood. The centrifugal blood pump is manufactured by assembling a bottom member 21 and a lid member 22, and compressing them in a direction in which the bottom member 21 and the lid member 22 approach each other by a deformation amount along their outer circumferential walls. The lid member and the bottom member are joined while in the compressed state in order to create a preloading force between the shaft member and bearings to resist the expansion due to pressurization of the blood during use.

A holding structure of an intervening member is provided for preventing the dropping-out of a wobbling-prevention member at an assembly time, and to extend an applicable range of rigidity of the intervening member to a low-side range. A baffle plate (2) is intervened between a torque converter housing wall (5) and an transmission case (3) (intermediate wall (6)), and a wobbling-prevention member (39) is a holding structure of the intervening member interposed between the baffle plate and the torque converter housing wall in a compressed state. Under the precondition, a bottom portion (31a (37a)) of a concave portion (31 (37)) is clamped between a head portion (41) and a bulging portion (42) of the wobbling-prevention member, so that the wobbling-prevention member is held in the bottom portion of the concave portion reliably even during the operation. Also, an inside of the head portion of the wobbling-prevention member is hollow, so when the head portion is crushed and deformed, the air inside the head portion is discharged to the outside through an annular gap (43) to reduce a compressive load relative to the baffle plate.

Ski Binding Heel Unit

An improved ski binding heel unit comprising a lateral heel release mechanism to release the heel of a ski boot from a ski is disclosed. The ski binding heel unit typically includes an independent vertical heel release mechanism, an independent lateral heel release mechanism, and a longitudinal pressure compensator. The improved ski binding heel unit allows a reduction in the height of the heel pad. This reduction in heel pad height is generally achieved by eccentrically positioning two or more of the springs within the heel unit while superpositioning the resultant centroid of the forces of friction between the lower housing and mating heel track structures that house at least one of the eccentrically positioned springs to foster smooth longitudinal displacement of the lower heel housing when the ski flexes and counterflexes.

An air conditioner is disclosed which includes a pressurizer for pressurizing a suction-side refrigerant sucked into a compressor, and an auxiliary condenser for condensing a discharge-side refrigerant discharged out of the compressor. Accordingly, it is possible to raise the evaporation pressure of the suction-side refrigerant sucked into the compressor, and to reduce the condensation pressure of the discharge-side refrigerant discharged out of the compressor. As a result, the difference between the suction and discharge pressures of the compressor can be reduced, so that a reduction in compression load can be achieved. Thus, a reduction in power consumption can be achieved.
