In a neck support for a chair, a head cushion is articulated, via an articulation bearing, on a guide sleeve displaced on a retaining bar, articulated on the top edge of a backrest via a further articulation bearing, the retaining bar and the guide sleeve being of rectilinear design, this resulting in linear height adjustability of the neck support. The bottom articulation bearing and preferably also the top articulation bearing each comprise a cylinder on the retaining bar and two cylinders on a bearing foot or on a link plate, it being possible for the first cylinder to rotate in a controlled manner between the two second cylinders via blocks.

A speculum provides visual access to a body cavity, and such instrument is used by physicians for vaginal examination. The speculum comprises a handle having a frontal portion and a rear portion slidingly secured to the frontal portion. A blade angle positioner is pivotally connected by a pivot connection in a top end portion of the handle rear portion, whereby to angulate a top blade removably secured to a top blade connector anchor at a forward projecting end of the blade angle positioner. The handle frontal portion has a bottom blade connector anchor in a top forward end portion thereof. The top and bottom blades each have a connecting end provided with clamp connectors for removable engagement with a respective one of the top and bottom blade connector anchors. The blade angle positioner arrests the handle rear portion at a desired selected position by transfering a biasing force applied onto the blades when inserted into a body cavity and the blade connected to the blade angle positioner is in tension with cavity walls.

The invention is a double-hinged sill for adjustable securing the panels of a handrail system to a floor, the sill has U-shaped channel. A pair of hinged plates is pivotally mounted within the channel. A cylindrical hinge member is provided at the bottom end of each of the hinge plates and extends the length of the hinge plate. A groove for receiving the cylindrical hinge member is provided at the bottom of the sill. The pair of hinge plates is aligned within the sill as mirror images. A series of adjustment and locking screws are provided along the length of the sill and extend there through from either the top of the sill or the sides of the sill and a readapted to selectively impinge against the pair of hinge plates to movably adjust the plates inwardly against a glass panel or outwardly away from a glass panel to vertically align the same and lock it into place.

A hinge plate accommodation element for attaching a hinge plate has a holder bracket that has a first shank for attachment on the frame side and an angled short shank, a bracing plate that is connected with the short shank of the holder bracket, so as to pivot, a pressure plate that is disposed on the bracing plate with binding screws, and can be adjusted relative to the bracing plate by means of activation of the binding screws, and adjusting screws that are inserted into bores of the holder bracket, so as to rotate, and engage into threaded bores of the bracing plate.

The invention discloses an adjustable width packaging bag forming device, a bag making device, a packaging machine and a method. The bag making device is included. A traction device and a heat seal device are arranged above the bag making device. A width adjusting device adjusts the distance between different sub bottom plates in a front bottom plate and a rear bottom plate through a lead screw sliding block mechanism, and accordingly bottom plate width adjustment is achieved. The lead screw sliding block mechanism is adopted as the width adjusting device for an automatic adjustable width noodle packaging bag forming device system, the four bottom plates are fixed to the width adjusting device, when the lead screw sliding block mechanism works, the adjusting range is accurate, the adjustable width packaging bag forming device is suitable for multiple widths of packaging bags, and a very important significance is achieved for the three-dimension forming effect of the packaging bags.

An anchor assembly is provided that permits adjustment of the brake shoes in a drum brake to account for wear. The assembly includes first and second adjuster shafts each having a plurality of threads and first and second pilot connectors. The pilot connectors each have a plurality of threads in engagement with the threads of a corresponding adjuster shaft. The pilot connectors each engage one end of a corresponding brake shoe. Rotation of each adjuster shaft causes longitudinal movement of a corresponding pilot connector in engagement with a corresponding brake shoe along an axis to adjust a position of the brake shoe.

The invention relates to a medical or dental treatment chair (1) having a seat part (2), a back part (4), a carrier part (16) arranged on the back part (4), an intermediate lever (23) which with its one end is pivotably connected with the carrier part (16), a head support lever (24) which with its one end is pivotably connected to the other end of the intermediate lever (23) and carries a head support pad (21), and an intermediate lever adjustment motor (M3) which is effective between the carrier parts (16) and the intermediate lever (23). For the support function there is provided a head support lever adjustment motor (M4) which is effective between the intermediate lever (23) and the head support lever (27).

The invention discloses an automatic lifting type stirring device. The device comprises a bottom plate, a stand column, a stirrer, a lifting plate, a lifter, a first connecting rod, a second connecting rod, a first sliding block, a second sliding block and a third sliding block. The stand column and the second sliding block are each provided with a sliding groove, the stand column and the lifter are vertically installed on a base. The first sliding block, the second sliding block and the third sliding block are sequentially arranged in the sliding groove of the stand column from top to bottom, the second sliding block is further fixedly connected with the lifter, the lifting plate is horizontally installed on the stand column through the first sliding block, the stirrer is installed on the front side of the lifting plate, and one end of the first connecting rod and one end of the second connecting rod are hinged into the sliding groove of the second sliding block. The other end of the first connecting rod is hinged to the lower end face of the lifting plate, and the other end of the second connecting rod is hinged to the third sliding block. The device has the advantages that through the structural design of the connecting rod and the sliding blocks, the lifting plate can ascend and descend in a horizontal state, and the stirrer and the lifting plate synchronously and vertically ascend and descend, so that a stirring area in the vertical direction is finely adjusted.

The invention discloses an adjustable power supply linear program control device, comprising a control module used for arranging control flows and program parameters, real-time receiving the real-timevoltage and current values collected by a data collecting module, gaining a comparison result after comparing the real-time voltage and current parameter values with the given voltage and current parameter values, carrying out the rotation speed control of a motor module according to the comparison result till that the real-time voltage and current values collected by the data collecting module are equal to the given voltage and current parameter values or the adjustment of the voltage and current complies with the given program parameters, and stopping driving the motor module; the data collecting module used for sending the collected real-time voltage and current values of the adjustable power supply to the control module; the motor module used for receiving the driving of the control module and adjusting an adjusting knob used for adjusting the adjustable power supply. The adjustable power supply linear program control device realizes automatic control and automatic disposal to thepower supply adjustment and data collection of voltage and current and avoids the problem that errors can be caused by manpower factor.
