Title: Liquid nitrogen coolant for blades of meat cutters - also cools meat and bowl cover after vaporisation
Inventor: SCHMIDT EDWIN
IPC: F25D3/10
Filed: 1989-08-16
Abstract: Cryogenic gases are applied to meat cutters with a revolving toroidal bowl by admitting liquid nitrogen to the meat being minced by the set of cutters and by extracting the gaseous nitrogen into a meandering pipe on the inside of a narrow hollow semicircular bridge over the bowl. The bow-shaped hollow duct (1) which is heat insulated on the outside matches the shape of the outer surface of the cutter space of a meat cover lid. One end of it forms an outlet connection (2). Its under side carries a meandering pipe (3) which terminates in the connection (2) as an inlet for gases or liquids (4) and with a hose (5) for reflux fluid. A heating cable (6) is arranged between the meandering turns. Bolts with wing nuts (7) pass through perforations. All connections are grouped together in the connection (2). A detachable insulated pipe (8) for liquid N2 is passed through the duct (1) to carry the refrigerant to the cutting space; the evaporated gas is extracted through the hollow duct. ADVANTAGE - This absorbs the frictional heat created by the meat cutting operation and utilises the evaporated N2 for indirect cooling of the bowl cover and of the meat in the bowl.

Title: Open=end rotor spinning frame - has robotic link mechanism to increase belt pressure at re-commencement of spinning
Inventor: STAHLECKER FRITZ
IPC: D01H4/12
Filed: 1989-12-21
Abstract: The tangential belt drive for an open-end spinning rotor frame is equipped with a pressure roller which lifts when the brake is applied, and when the brake is lifted, the link mechanism reapplies the pressure roller with additional force for spinning in. Pref., two levers adjacent and parallel, protrude at the front of the frame, and are activated by the service robot. When lever is forced upwards, the coupling to the arm falls, with linkage against spring balance, to raise the pressure roller, which is pressing the belt against the rotor spindle. At the same time, the hook coupling brings down the arm to raise the stud between the spring loaded caliper, closing the brake pads on to the rotor spindle. ADVANTAGE - The belt is only heavily stressed on spinning in, and reverts to normal pressure afterwards, saving on energy and on belt wear.

Abstract: A procedure for the inspection of occurring or spreading cracks or fractures in materials, workpieces, structural parts of  structures, especially in regions where there is a dn of earthquakes or rock movements during tunnel constructions, whereby changes in the electrical field near expected fractures or cracks are detected and subsequently evaluated.  The points in time, the durations and frequencies are singly, jointly or in any combination detected and evaluated for which the electrical field changes exceed a predetermined threshold value.  Single measurements are summed, recorded  versus time or statistically evaluated.  On reaching a predetermined threshold value, an alarm signal indicates a dangerous condition or occurring damage.  The arrangement comprises at least one probe element consisting  of a metal or a probe element having a similar high electrical conductivity which is connected to the input of a high-frequency amplifier, whose output is attached to a recording or evaluation unit. USE/ADVANTAGE - The arrangement/method can be employed to detect an early material failure e.g. in nuclear plants, bridges, buildings, aeroplanes, etc.  The arrangement allows also the inspection of materials for cracks and fractures which are not ferro-magnetic.

Title: Vehicle automatic transmission control method - performing torque control to reduce torque shocks during gearchange
Inventor: NOGUCHI NAOYUKI
IPC: B60W10/10
Filed: 1990-04-04
Abstract: The automatic transmission uses a control of the torque during the gearchange to minimise the torque shocks. The motor torque is varied as the speeds of the different parts of the transmission change and depending on where the transmission is in the gearchange.  The system detects the start and finish of the gearchange action to define the control region. The control is via a programmed control, partly through an iterative process. The torque can be temporarily adjusted by a variation of the engine timing. The control is modulated w.r.t. throttle setting, with the control inhibited if the throttle setting alters during gearchange. This enables the driver to have complete control, e.g.  during braking or sudden acceleration. ADVANTAGE - Improved comfort, less damage to transmission.
