Title: Commutator brushes for small motors - are divided into parallel paths joined by resistor to reduce sparking
Inventor: SCHMIDER FRITZ
IPC: H01R39/54
Filed: 1977-06-03
Abstract: Brushes formed from metal strips are for very small motors with few commutator segments. To reduce sparking the brushes are divided into at least two parallel paths (1, 2; 3, 4) which are circumferentially displaced. These parallel paths are joined at the terminal end by damping resistors (5, 6). The damping resistors assist current decay in the coil being commutated, and help restore normal current flow but in the opposite direction. The resistors may be fixed value units or voltage dependant diodes or varistors. The reduction in stray fields due to reduced arcing at the brushes diminishes electrical interference with other appts.

Title: Load handling vehicle with lifting forks - has lazy tongs linkage controlled by tow actuator cylinder and lever systems
Inventor: WEHRMANN JOBST
IPC: B66F9/065
Filed: 1979-01-22
Abstract: The load handling vehicle with lifting forks (6) uses a system of scissor linkages forming a lazy tongs system to raise the lifting forks from ground level to an upper level where the scissor linkages form a nearly vertical column. The action is controlled by further levers (19, 20, 21) forming a Z shape between a point (23) behind the forks and another point (27) at the rear of the vehicle structure (1). The forward lever (20) forms an extension of the piston rod of an actuator cylinder (26). A second cylinder (33) above this is connected with a short lever (28) which forms with it and a lever (29) at the rear, a second 'Z'-shape.

Title: Ratchet spanner for tightening jaws of vice - has stirrup to enable user to operate vice with hit foot
Inventor: SKRZYPSKI EDUARD
IPC: B25B1/24
Filed: 1979-03-28
Abstract: When dealing with heavy workpieces which require the use of both hands to lift them, it is difficult to place them in a vice without the use of special lifting tackle since the operator has no free hand to rotate the vice spindle. The problem is solved by making a square hole in the end of the vice spindle to receive the square end of a ratchet spanner. The ratchet spanner has a stirrup attached to its outer end by a metal strip. The user can then rotate the vice spindle with his foot whilst holding the workpiece with both hands.

Title: Vinyl chloride mfr. - by cleavage of 1,2-di:chloroethane, with recovery of heat from the hot cleavage gases by indirect heat exchange
Inventor: CZEKAY ARNO DIPL CHEM DR
IPC: C07C17/25
Filed: 1979-03-31
Abstract: In a process for recovering pyrolysis energy in the prodn. of vinyl chloride, liq. 1,2-dichloroethane (I) is preheated under pressure, vapourised and led in the gaseous state into a cleavage zone. After incomplete thermal cleavage the hot cleavage gases under pressure are cooled in a heat exchanger through which a heat transfer or cooling agent is passed. The heat exchange medium, after extracting heat from the hot gases, is led off for use in another part of the process. The cooled gas stream is treated in a number of successive distn. zones to recover HCl, vinyl chloride, unconverted (I) and high- and low-boiling components. Process allows utilisation of the pyrolysis heat evolved during cleavage of the (I), and which was previously lost. The heat is esp. used to heat the distn. columns in the prod. sepn. stage.

Title: Brake control valve with safety interlock - has safety catch to lock dual control into one element on circuit failure
Inventor: SCHAEFER ERNST DIETER ING GRAD
IPC: B60T11/34
Filed: 1979-06-06
Abstract: The control valve for a dual braking circuit has a floating piston (16) inside a control sleeve (18) to balance the brake pressure in the two circuits. If one circuit fails then the sleeve is displaced and a mechanical lever locks the floating piston to isolate that circuit and enable the other circuit to ooerate with full pressure. The mechanical safety catch (20) tilts and oresses the floating piston against the respective control valve (10,11) to override the modulating effect of the brake valve. Full braking is then possible on the remaining brake circuit.
