Title: Signalling switch for vehicle steering column - has opening in switching lever underside for latching pin coupled to contact spring
Inventor: ERDELITSCH HERBERT
IPC: B60Q1/14
Filed: 1974-06-07
Abstract: The switching lever displaces the switch carrier horizontally, being vertically deflectable on the carrier. A switching rod is axially displaceable in the lever (16) which in the lever of the steering column switch has an underside opening (42) through which a latching bolt (20), coupled to a contact spring (19) is inserted in a latching receptacle (29) of the switching rod (30). The contact spring is guided in the receptacle of the carrier (11), and abuts a terminal contact (22) of the contact carrier plate (10). On displacement of the contact spring over the axial displacement of the switching rod in the lever, the contact spring abuts additionally a contact strip (24) of a further terminal contact (23) of the carrier plate.

Patent DE-2434097-A1 (DE)
Title: Gas filter
Inventor: HAGE STANISLAS
IPC: B01D46/04
Filed: 1974-07-16
Abstract: An appts. for the continuous filtering of gases has a filter medium between an inlet and outlet chamber, the outlet being under vacuum provided by a fan. The outlet chamber is divided into >=2 sections, each of which has a value which may be used to isolate it from the fan. Upstream of the valve is a port also connected to a valve which can be opened to connect it to a zone which may be under pressure or at atmospheric pressure. A controller arranges for only one of the valves to be open at a time. In a cleaning cycle, the gas flow to one section is reversed while the other section(s) continue to filter.

Title: Flame-proof AC squirrel-cage motor - has first winding for second flame-proof class and additional winding to comply with third class
Inventor: ELENDER JOSEF DIPL ING
IPC: H02K3/28
Filed: 1974-07-18
Abstract: The flame-proof a.c. squirrel-cage motor has a winding (1) with a specified number of conductors in the stator to comply with the (G2) flame-proof classification, and an additional winding (2) with a different number of conductors connected in to comply with the (G3) flame-proof classification. Both windings are insulated so that they fall into a higher insulation class than is necessary for flame-proof machines. By suitably choosing the ratio between the numbers of conductors in the two windings, similar values for the torque and for current during starting and short circuit can be obtained.

Title: High speed braking system for tape recorder - with inital braking through spool motor followed by mechanical braking stops tape
Inventor: WIEDENROTH BERND ING GRAD
IPC: G11B15/48
Filed: 1974-07-27
Abstract: The system is designed for a dual motor tape drive in which operation of the brake interrupts the current supply to the operative motor. After operation of the brake a braking voltage is applied to the let-off spool motor to generate a torque opposing to the let-off. A signal is generated only during take-up by the take-up spool, and when this signal disappears completely or almost completely the let-off spool motor is disconnected from the braking voltage. Pref. after electrical braking the spools are braked mechanically under the control of the tape tension.

Title: Agricultural trailer with detachable loads - has axially moving guards on cable drums or loading winch
Inventor: KRONE JUN BERNARD
IPC: B60P1/64
Filed: 1974-09-13
Abstract: The load support for the agricultural tractor is removable and is winched on and off the chassis by cables attached to winches. The cabbedrums (65) have spiral grooves to thread the cable accurately, so that both cables are hauled in at the same rate. The cable winding action is protected by cowls (66) positioned most of the way around the drums, with the cowls sliding laterally on guides (71). The cowls are protected from rotating about the guides by means of stops and the cables are fed to the guides by hollow ducts (64) linked to the cowls. The cowls prevent any debris, or crop etc., from being caught up in the windings.
Patent DE-2449442-A1 (DE)
Title: Liquefied natural gas transport system - uses liquid nitrogen for supercooling in heat exchanger before transfer to storage tank
Inventor: REHDER REIMER DIPL ING
IPC: F25J3/02
Filed: 1974-10-17
Abstract: A system for the transport of liquefied natural gas from a producer to a consumer uses liquid nitrogen for the supercooling of liquefied natural gas in a heat exchanger before it reaches the final storage tanks. The supercooled natural gas is transferred from tanks on vehicles (oil tankers or road vehicles) to the storage tanks at the consumer's either by pumps or by an excess pressure of nitrogen. This greatly reduces the production of flash gas in the storage tanks and during transport. Contact of the still existing gas in the storage tank with the supercooled gas re-liquefies it; the losses of gaseous natural gas in the storage tanks are greatly diminised. The empty cargo tanks of an oil tanker can now be kept filled with nitrogen so that the risk of an explosion is avoided.

Title: Positioning aid for machine tools - uses incremental encoder and counter with final position accuracy compared with predetermined tolerance
Inventor: STEINBACH WOLFGANG DIPL ING DR
IPC: G05B19/23
Filed: 1975-04-25
Abstract: A positioning device for the table of a machine tool e.g. milling machine, is effected by an incremented encoder operating into a binary counter. A fast traverse followed by slo final approach is coupled with a comparison of final position with a permitted tolerance. The required position is selected together with the point at which fast traverse is disengaged and the number of steps to be made at slow final approach. A control stage generates the number of steps to be made with fast traverse. A comparator receiving the counter output generates the first change down signal and a second comparator the second change down dependent upon the number of increments required. A final stage compares the final positioned accuracy achieved with the accepted tolerance to indicate acceptance or reflection.

Title: Gas emission plant for liquids - with float, switches on floating gas collector controlling gas emission and circulation
Inventor: REBHAN DIETER ING GRAD
IPC: C02F3/00
Filed: 1975-09-30
Abstract: A plant for the immission of a finely distributed gas into a liquid includes a floating container, open at the bottom, to collect any gas which has not been absorbed by the liquid. Level contact switches on the container monitor its depth of immersion and control the valves for the gas immission, and the pump and the valves for the gas circulation system. This utilises the fresh gas to the highest efficiency and prevents wastage by release of the collected gas. Automatic control depending on the impurity concentration in the liquid is possible.

Title: Nickel cadmium storage battery charging circuit - has series transistor in charging current path and voltage comparator with temp. compensation
Inventor: SCHWERIN RALPH
IPC: H02J7/00
Filed: 1975-10-07

Title: Producing charged powder particles - using parallel linear electrodes embedded in single planar insulator layer
Inventor: ITOH TSUTOMU
IPC: H01T14/00
Filed: 1976-01-09
Abstract: In a pair of surface-shaped silent discharge electrodes opposed to each other and separated by a predetermined space, phases of alternating voltages are applied to the respective silent discharge electrodes shifted in phase with respect to each other. Thus, a silent discharge may arise alternately on either one of the electrode surfaces. A second alternating voltage is applied between the silent discharge electrodes and is alternatingly varied at a frequency twice as high as the frequency of the first alternating voltages. Powder particles are passed through the space which separates the pair of surface-shaped silent discharge electrodes and charged in either positive or negative polarity.

Title: Moulded housing for vehicle light cluster - with each lamp in separate tubular chamber for optic isolation
Inventor: RAFALZIK SIEGFRID
IPC: F21V19/00
Filed: 1976-02-07
Abstract: The housing for the multi lamp cluster has a one piece moulded plastic base (11) whose separate chambers (12,13) are formed by perpendicular walls, with one wall around each chamber, forming tubular cells.
