Patent DE-2363086-A1 (DE)
Title: Steering control for hydrostatic transmission - with parallelogram linkage to couple together two variable pumps for wheel motors
Inventor: WILLIAMSON WILLIAM APLIN
IPC: B62D11/18
Filed: 1973-12-19
Abstract: The fork lift truck, or similar vehicle is driven by independent hydraulic motors on the rear/front wheels on opposite sides of the vehicle. The wheels are differentially driven to provide a steering control, with the hydraulic pumps for the two hydraulic circuits linked by a special linkage. This alters the motor supplies differentially w.r.t. accelerator setting and sterring control setting. The system is ore versatile than conventional steering in that a fast turning circle can be set up by reversing one of the motors.

Title: Constant composition fuel gas generator for I.C. engine - has divided air supply to the catalytic reaction chamber
Inventor: MENTSCHEL HELLMUTH DIPL ING
IPC: F02M27/02
Filed: 1974-03-19
Abstract: The fuel gas with constant composition is used to run an engine whose loading may vary. Evaporated fuel, air and a proportion of exhaust gas are fed into the catalytic reactor for conversion into fuel gas. A proportion of air is preheated in a counterflow heat exchanger. The temperature within the whole active catalyst necessary for the heterogeneous catalytic conversion is held constant in order to prevent temperature gradients between the inlet and outlet of the catalytic reactor. The air is supplied into the reaction chamber containing catalyst by a number of parallel channels whose outlet ends are close to the catalyst surface. The air supply channels can be moved axially in order to cover some of the outlet openings in other pipes. Air flow can also be regulated by valves.

Title: Corrugated pipe or bellows with reinforcing rings - uses inner split ring secured by circumferentially wound strip
Inventor: AYDT MANFRED
IPC: F16L51/02
Filed: 1974-04-09
Abstract: The corrugated pipe or bellows has a wide trough between two successive corrugations. A ring formed from a strip of rectangular cross-section with two rounded corners to suit the profile of the corrugations fits closely around the outer surface of the trough. The ring is then secured in position by winding a thin flexible strip of metal or plastics around the outside. A gap is left between the edges of the strip and the corrugations to allow free endwise movement of the bellows. Alternative designs use wire instead of the strip and form the ring from a channel section profile.

Title: Piston ring locking arrangement - has ring pressure increasing spring and translation-preventing plate between ring and spring
Inventor: SCHOENLAU HERBERT ING GRAD
IPC: F16J9/06

Title: Heat pump with refrigerant working fluid - has solenoid valve in high pressure side closed at shut down
Inventor: PETER ERWIN DIPL PHYS
IPC: F25B29/00
Filed: 1975-03-11
Abstract: The heat pump has an evaporator (11) with a heat source (15), a condenser (12) with a heat load (17), a compressor (13) and a thermostatically controlled expansion valve (14). There is a solenoid valve (18) on the high pressure side between the condenser (12) and the expansion valve (14). When the controls (19, 20) stop the compressor, the solenoid valve (18) shuts before the compressor stops and the compressor empties the low pressure side of refrigerant before it stops. This ensures that while the compressor is stopped there is no refrigerant on the low pressure isde which can be absorbed by the lubricating oil so that the oil does not have to be heated to expell refrigerant before the compressor is restarted.

Title: Pattern programming arrangement for circular knitting machines - resetting knob puts all pattern transmitting elements into inactive position
Inventor: KUEHN FALK
IPC: D04B37/04
Filed: 1975-04-26
Abstract: A pattern programming device for adjusting the needle jacks of a circular knitting machine according to pattern, or withdrawn to an inactive position, in either plate, according to pattern, or withdrawn to an inactive position, in either of which locations they are locked. When the actuating arms are all aligned according to the pattern, the programming device is brought up against a stop and the patterning bits or needle jacks are aligned correspondingly. The pattern transmitting elements consist of two-armed levers pivoting on a common axis, the one limb of each of which forms the pattern actuating member, all of which can be set back to neutral by turning knob. The device can be set up to the pattern by tilting the transmitting elements into the active position in which they are automatically locked. The jacks or the segments of the patterning drum are then positioned against the nose of each corresponding transmitting lever and the locking bolts are replaced. If the pattern needs to be erased or altered the reset knob is turned. All the transmitting levers are then unlocked and put in the inactive position.

Patent DE-2530587-A1 (DE)
Title: Determining and recording irregularities in a running yarn - by means of electrical signals representing changes in loading
Inventor: DERICHS JOSEF DR
IPC: D01H13/22
Filed: 1975-07-09
Abstract: Irregularities in a yarn running from an open end spinning aggregate are measured and recorded by means of a pressure sensitive arrangement which monitors the force exerted on the running thread, or the differential quotient of the force-time function may be measured. The dimensions ascertained are converted into electrical signals and processed by an electronic evaluating circuit to show the relative uniformity or the mass of the running yarn exerting the force. This provides a simpler method of ascertaining, quite independently of the yarn composition or its quality, the irregularities in the thread, based upon the recognition that mass forces act on the open thread which are proportional to the regularity or irregularity of the running thread.
