Patent DE-2818857-A1 (DE)
Title: Operator reservation of lines in electronic telephone exchange - allows intervention in programme controlled process for manual operation
Inventor: DIDAKOWSKI HANS JUERGEN ING GR
IPC: H04M3/60
Filed: 1978-04-26
Abstract: A system is esp. useful for private programme-controlled branch telephone exchanges. It allows the operator to intervene, reserving links for manual control. When the locking button (SPT) at the operator position (BPL) is engaged, a blocking element (SP) switches one contact (sp1), illuminating an indicator lamp (SPL) at the operator position, and a second contact (sp2). The second contact (sp2) makes two connections (pr1, pr2) in the programme control unit (PST), so that a relay (BSG), independently of the programme, signals the engaged condition for the corresponding exchange links, and reserves them for control by the operator.
Patent DE-2821456-A1 (DE)
Title: Lock for telephone subscriber's appts. - has plunger closing security contacts when pushed in and unlocked by key that disengages projection from holes in plunger
Inventor: NIEDERHOEFER KARL-HEINZ ING GR
IPC: H04M1/667
Filed: 1978-05-17
Abstract: The lock has a plunger (1) acting on a spring contact (4), similar to a push-button. The sides of the plunger's shank have holes into which hooks, projecting from the inside of the well along which the shank moves, engage and hold the plunger in its 'in' position, i.e. spring contact touching fixed contact (5). The plunger remains locked in this position until a key is inserted down inside the plunger. The key has an end shaped so that it forces the projections out of the holes. The plunger can then be raised so that the contacts separate.
Patent DE-2821602-A1 (DE)
Title: Angled-yoke cable twister - has a rotary mass for each supply spool to compensate for changes in moment of inertia
Inventor: HOPPE BERND
IPC: G02B6/44
Filed: 1978-05-12
Abstract: In an angled-yoke cable twisting machine, with a mechanism to reverse the yoke carrying the strand supply spool, there is an additional mass rotating on the yoke axis for each supply spool. This mass is coupled to rotate against the direction of the spool. A positive guide is provided, meshed in with standing cog wheels, used to couple the two rotating masses so that they rotate in opposite directions, using sprockets driven by a toothed belt. The design gives a compensation for changes in the moment of inertia so that the capacity of the machine can be increased.

Title: Flow control valve for pressurised liq. - has spring-loaded pressure balancing piston between pressures up and downstream of throttle
Inventor: KAMPMANN HELMUT PROF DIPL ING
IPC: F15B13/04
Filed: 1978-06-19
Abstract: The flow control valve (11) for pressurised liq. comprises a variable throttle (13) and a pressure balance (12) which contains an axially slidable piston (17) movable in one direction by the pressure downstream of the throttle and the force of a spring (27) and in the other by the pressure (P1) upstream of the throttle. The piston carries a co-axial (31) rod (22) with a flat end face (33) which faces a co-axial throttle bore (32) through which the pressurised fluid enters at a flow rate (Q3) with the pressure (P1) upstream of the throttle (13). The cross-section (A2) of the face (33) may be little greater than that (A) of the bore (32).

Title: IC engine exhaust gas cleaning system - has cyclone to extract soot for recycle to inlet manifold with flow controlled by photocell in exhaust pipe
Inventor: HORSTMANN BERNHARD
IPC: F02M26/15
Filed: 1978-07-31
Abstract: The system uses a cyclone separator (8) to extract the soot from the engine exhaust gas. This soot is recirculated (15) to the inlet manifold (2) downstream of the filter (4), the cleaned gas being discharged from the cyclone via a silencer (12). Soot flow is controlled by a metering valve (14) in the outlet from the cyclone. The valve is electrically operated by a photoelectric-cell unit (16, 17, 18) in the exhaust line (6) leading to the cyclone, via a regulator (21).

IPC: B60P3/022
Filed: 1978-10-26
Abstract: The vehicle (1) has a vehicle frame (3) and an auxiliary frame (7) which is arranged thereon. In addition, it is constructed with a jib (13) which rests near to the driver's cab (10) on supports (14, 15) which are arranged at a distance one behind the other, the said jib (13) having two or more telescopic sections (16, 17, 18). The outer telescopic section (18) receives at its free end a lifting device (20) which can be extended by means of the movable telescopic sections (17, 18) beyond the rear of the vehicle into an open side of the unitised unit (23) in order to engage on the unitised unit for the purpose of lifting and lowering it and to load the unitised unit on to the vehicle (1) or unload it therefrom. Since the jib (13) is a member subject to bending and must have a sufficiently static height and on the other hand the lifting device must be extended without friction through the opening into the unitised unit, the front support (14) of the jib (13) is constructed as a pivot bearing and the rear support (15) can be raised and lowered by several centimetres so that the jib (13) can be moved into a lowered oblique position in order to enter the unitised unit (23) and can be moved into the raised position in order to lift up the said unitised unit (23). <IMAGE>

Title: al sensor differential magnetic field probe adjustment - using mild steel movable pieces on carrier or retractable sensor wires
Inventor: NISSEN WALTER DR
IPC: G01R33/022
Filed: 1979-07-20
Abstract: An arrangement enabling adjustment of magnetic differential field detectors contg. two sensors enables the accuracy to be considerably increased compared to conventional arrangements. This is achieved simply and results in a considerably cheaper detector applicable to ship defence equipment responding to noise fields much weaker than the earth's magnetic field. The sensors have mild steel pieces on or near them and movable in one or more directions or are constructed with movable components. The movable elements can be fixed in position. If separate mild steel pieces are used, they are rings, cylinders, discs or segments movable on an magnetic carrier ring on the probe. If the sensors have movable components these may consist of wires retractable and able to be bent w.r.t. them.

Title: Antilocking rail vehicle brake system - has control valve designed for largest, and iterative pressure control for smaller brake cylinders
Inventor: SAUMWEBER ECKART DIPL ING DR
IPC: B60T8/64
Filed: 1979-07-26
Abstract: The brake force control system with anti-lock protection is intended for a rail vehicle comprising pressure operated brakes with brake cylinders and a pressure control valve. The control system receives signals representing the circumferential wheel velocity, and derives acceleration or deceleration. It takes account of limit values and vehicle speed and reduces holds or increases the brake pressure accordingly. The pressure control valve is arranged to produce optimum pressure conditions for the largest cylinder it is possible to use. For smaller volume cylinders the optimum pressure is approached by alternating pressure increase and hold or alternating periods being determined by the control.

Title: Transparent heat insulating mat - for window panes made of spaced foils attached to panes by suction cups
Inventor: KLINGSCH GOTTFRIED
IPC: E04B1/78
Filed: 1979-11-15
Abstract: Transparent heat insulating mat for glass window panes, specially for workshop and industrial building use, consists of two foils which are welded together to form a cushion. The two foils can be joined either by parallel vertical strips or by a third foil folded to a zigzag shape. A valve permits the filling of the enclosed spaces with a gas. Suction cups along a peripheral flange are used to attach this insulating mat to a glass pane. This is a much less expensive way of heat insulating than double glazing and has little effect on the light transparency.
