Title: Automatic equaliser for transmission systems - has auxiliary networks for sensitivity signals generation
IPC: H03H15/00
Filed: 1974-08-30
Abstract: These signals automatically adjust parameters of the main electronic circuit, or of the other network, in order to make a power index a maximum or a minimum; it comprises further a sensitivity model generating N sensitivity signals, where N is the number of adjustable parameters in the main network; the sensitivity model is divided in, at the most, N-1 sub-networks, with one or several separate inputs. They are not made more complicated than the main network. The improvement offered by the invention lies chiefly in the lessening of the switch circuit parameters necessary to ensure the preset standard and the quickness of operation readiness.

Title: Vehicle safety belt monitoring system - gives visual or audible reminder alarm if buckles not connected before moving off
IPC: B60R22/48
Filed: 1975-05-05

Title: Lubricant piston pump pneumatic oscillator - consists of piston with reversing valve and hydraulic brake
IPC: F04B1/00
Filed: 1976-04-23
Abstract: The pneumatic oscillator is adjustable within a frequency range, and is esp. for use as a drive for lubricant piston pumps. The oscillator consits of a piston (71), a reversing valve and a hydraulic brake unit (62, 72, 74). During the working stroke, the piston is charged with pressurized air on one side, and is displaceable against a return spring (86). The reversing valve is automatically reversed in its end positions, and during the return stroke, produces a pressure equalization between both sides of the piston. The brake unit is connected to the piston, is adjustable, and is active only during the return stroke. The oscillator may be used as a drive for a lubricant displacement pump (63, 64, 66), e.g. a single acting piston pump, and the brake unit may be separate from the lubricant circuit.

Title: Power circuit breaker with lockable contact system - has locking lever movable by contact opening to locking position for recoil preventing
IPC: H01H71/50
Filed: 1976-11-18
Abstract: The lockable contact system has at least one stationary and one moving contact. The locking lever is used to prevent contact recoil. The locking lever (17) moves from its rest position by the breaking movement of the moving contact (11), and is hingeably mounted at one side. Over its path into the locking position it is first guided by the locking mechanism. After the breaker shaft has struck a counter bearing (20) it is projected into its locking position and engaged there behind a blocking stud (18), in order to prevent a recoil movement. Preferably the locking stud is in the form of a link motion. The locking lever may be guided by the lock mechanism in such manner as to bring a shoulder against a part of the mechanism in one rotary direction, while in the other direction the lever is freely movable.

Title: Tape transporter mechanism between spools - has spring exerting force on spool slides to keep driving roller engaged
IPC: G11B15/295
Filed: 1977-02-01
Abstract: The mechanism transports a flexible tape from an unwinding to a winding spool, the latter having a driving roller acting against its edge. Two slides carry the unwinding and winding spools, and are movable independently of each other to and from the latter. A frictional force is exerted on each slide by a spring mechanism resisting any tendency of the spools (23,24) to lift clear of the driving roller. As tape feed to the winding spool (24) begins, actuating mechanisms (51) briefly interrupt the force acting on the slide carrying the unwinding spool (23). The mechanisms can consist of electromagnets.
