Patent DE-2412129-A1 (DE)
Title: Terminal for water cooled cable feeding arc furnaces - uses heat resisting mounting for mechanical location of conductors
Inventor: GOODMAN DANIEL J
IPC: H01B7/42
Filed: 1974-03-13
Abstract: The object of the special mounting is to prevent the cable sliding out of the terminal in the event of a cooling water failure resulting in the solder running out of the joint. The cup shaped socket is sealed into the cable sheath in a leak proof manner. The ends of at least one conductor bundle are held, for example by crimping in a solid connecting piece with an L-shaped end. This is bolted into the base of the socket. The remaining conductor ends are embedded in solder to form the electrical connection with the socket.

Title: Automatic adjustment of typing machine backplate position - ensures correct offset between backplate and printing head regardless of thickness of paper or ribbon
Inventor: RENNEBERG FRITZ
IPC: B41J11/20
Filed: 1974-10-29

Title: Double integration AD converter for meteorology - linearises input switching correction circuit between clock and frequency divider
Inventor: FRIEDRICHS HANS-JOACHIM
IPC: H03M1/00
Filed: 1975-02-08
Abstract: The double-integration analogue-digital converter, for meteorological and medical measurements, linearises non-linear analogue signals and converts them into digital form for direct read-out. A clock generator (12) is used to correct the input non-linear characteristics. A correction circuit is switched in between the frequency-dividing counter (11) and the clock generator only during the interval when the reference voltage is being integrated. The integrator (2-5) alternately receives the reference and input signal at its input and feeds a comparator (6) at its output. The comparator is AND gate connected (7) with the outputs of a control circuit (10) and the clock generator.

Title: Control for aeroplane air brake - has bleed valve so operating jack reaches position in equilibrium with air flow force
Inventor: SCHWAERZLER HANS-JUERGEN
IPC: B64C9/32
Filed: 1975-07-04
Abstract: The force applied by a hydraulic operating jack and the opposing force exerted by the airflow on the flap are in equilibrium at various opening angles. The device consists of piston rod (5) and cylinder (4), pivoting respectively at (6, 8) on the brake and airframe. The jack is supplied with fluid from pipe (9) which has a flow restrictor (10). A return pipe (11) returns fluid to the reservoir. Connecting the pipes (9) and (11) is a sleeve valve (13). The fluid passing through the pipes (9) and (10) operates the jack to open the air brake. As the brake opens, it opens sleeve valve (13) through linkage (15), bleeding off a certain amount of fluid through pipe (12) to return pipe (13). The amount bled off increases progressively as the brake opens until an equilibrium position.

Title: Hand operated metering pump - has adjustable locking ratchet which sets volume pumped and has two stage movement
IPC: F04B53/14
Filed: 1975-08-16
Abstract: The pump has a piston (2) reciprocating in a cylinder (1). The piston is on the end of a rod (3) which runs through a guide sleeve (5b) which itself terminates in a guide head (5a). A lever (8) pivoting on the end of the rod and sliding on the guide head (5a) enables the rod to be moved a fixed amount in the sleeve. The sleeve carries a ring (6) which trips over pivoting ratchet arms (7) on the inside of the casing (12). These arms fix the movement of the sleeve which carries the piston rod with it for the first stage displacement. They can be adjusted in position on the casing to vary the movement and thus alter the volume metered and pumped.
