A hydraulic transmission system for a zero-turn vehicle, comprises first and second transaxles each of which includes an axle, a casing supporting the axle, a fluid sump provided in the casing, first and second ports provided on the casing and opened outward from the casing, an HST circuit, a charge pump disposed in the casing, and a charge passage disposed in the casing to supply the HST circuit with fluid delivered from the charge pump. A first pipe connects the first ports of the transaxles, thereby making the flow of fluid from the charge pump of the first transaxle to the fluid sump of the second transaxle. A second pipe connects the second ports of the transaxles, whereby overflowing fluid of the fluid sump of the second transaxle is released to the fluid sump of the first transaxle via the second pipe.

An implantable device for the electrical and / or pharmaceutical stimulation of the central nervous system, especially the spinal cord, is suggested. The device comprises a conformable substrate which is primarily composed of a flexible and stretchable polymer, and a plurality of flexible electrodes and conductive leads embedded in the conformable substrate. Not only the substrate, but also the leads are stretchable. The substrate may consist of PDMS, and the leads may consist of a conductive PDMS, in particular, PDMS with an electrically conductive filler material, and may optionally be metal-coated. The device defines a multi-electrode array which may be employed for neurostimulation in the epidural or subdural space of an animal or human.

The invention provides a slurry bed reactor for FischerTropsch synthesis, comprising a shell, a group of gas-liquid cyclone separators, a baffle, a coil and a synthesis gas distribution plate, wherein the shell is provided with a slurry bed layer; the reactor is provided with a group of circulation cups (20) and a group of gas-liquid cyclone separators (10); bubble cap distributors are evenly arranged on the synthesis gas distribution plate; the cyclone separator diplegs (12) of the gas-liquid cyclone separators (10) extend into an expanded port (18); and a slurry bed layer (13) is positioned above the synthesis gas distribution plate (8). The number of the gas-liquid cyclone separators (10) is not larger than that of the circulation cups (20), and each gas-liquid cyclone separator (10) and the corresponding circulation cup (20) are coaxially arranged. Fluid in and out of the circulation cups (20) circularly flows to improve the reactor airspeed and space utilization ratio; and the cyclone separator diplegs (12) extend into the expanded port (18) to accelerate the circulation of the fluid in and out of the circulation cups (20).

The invention relates to the field of medical technology, in particular to a device and system for treating infertility and a method for regulating body fluids and nerves and meridians. This system is used to regulate body fluids and nerves and meridians to solve infertility problems caused by thin endometrium, low endometrial receptivity, premature ovarian failure, and low ovarian reserve. Compared with the prior art, the present invention has the advantages of: physical non-invasiveness, no side effects, simple operation, can improve body fluid circulation, increase blood supply to pelvic cavity, uterus, ovary and other reproductive organs, increase nutrient supply, and promote the formation of new blood vessels; The present invention can also improve the human reproductive endocrine system, improve hormone levels, balance the internal environment, and can effectively treat infertility problems such as thin endometrium, premature ovarian failure, low ovarian reserve function, and pre-IVF-ET adjuvant treatment.

The invention relates to a device (1) for producing radioisotopes by irradiating a target fluid using a particle beam (13). This device comprises an irradiation cell (7) that includes a cavity (3) for receiving the target fluid. A non-cryogenic cooling device cools the walls of the cavity (3). The cavity (3) has an inclined surface (15) downwardly delimiting the cavity (3) so as to evacuate the target fluid, which condenses on contact with the cooled walls, under gravity towards a metal foil (4) which closes off this cavity (3). The inclined surface (15) intersects the plane formed by the metal foil (4), making an acute angle (a) with said plane, so as to form with the metal foil (4) a wedge-shaped zone (18) capable of collecting, by gravity, the condensed target fluid.
