Patent DE-2444539-A1 (DE)
Title: Printed cct. with sequenced edge connector contacts - makes connections in predetermined sequence when plugged into edge connector
Inventor: GEHRMANN HERBERT
IPC: H05K1/11
Filed: 1974-09-18
Abstract: A printed circuit with edge connector printed contacts such that when the circuit is plugged in, the various connections are made in a predetermined sequence, is presented. This is achieved by a printed circuit format of the usual kind in which the contacts consist of finger shaped lands (3) which form an integral part of the printed pattern. These lands, however, are interrupted with open slots (4) at different points so that when the board is plugged into an edge connector the various contacts are made in a sequence determined by these slots. Thus it is not necessary for all strips to be activated when plugged in.

Title: Programmable card for testing and construction of electronic circuits - has matrix of transistor gates addressed by coding circuit
Inventor: LOEBLEIN FRIEDRICH DIPL ING
IPC: H05K1/00
Filed: 1974-10-08
Abstract: A programmable circuit card enables a number of circuit configurations to be readily established without the need for special fixed wire connections. The cross-point connections between a matrix of conductor strips on a circuit card depends upon a programmed matrix of transistor gates. Passive and active components are mounted on one side of the card and the underside carries the integrated transistor gate matrix. Inputs (E1 to E4) are assigned to rows of the matrix and outputs (A1 to A4) to the columns. A path between a specific input and output is dependent upon a specific address applied to coding circuits (G1 to G4). If an input (E3) is to be transmitted to an output (A2), then a code combination (a3b3) must be applied to the coding circuit (G3) to gate the appropriate transistor (T23).

When the actuator is released, the adjusting member is returned into the first position by the pre-load. The actuator contains a hydraulic/cylinder mechanism, the cylinder being charged by a hydraulic pressure fluid, so that the piston acts onto the adjusting member. The preload elements contain springs, acting in the opposite direction.

Title: Waste heat energy recovery process - uses intermediate fluid operating from below to above its critical temp. to move pistons by resultant expansion
Inventor: KIRCHHOFF JOACHIM DIPL ING
IPC: F01K25/02
Filed: 1975-06-07
Abstract: Exhaust steam passes through a multiway valve to a condenser where it condenses in the outer chamber and heats a fluid in the inner chamber. This fluid is heated from about 20 deg.C below to about 40 deg.C above its critical temp. The resulting vol. expansion is transferred to hydraulic oil in a transducer and the oil drives the pistons in a series of cylinders to which it is admitted in sequence by control valves. The pistons drive the shaft of a generator through free wheel mechanisms. The multiway valve then passes the steam to further identical systems while the fluid in the first is cooled to contract its vol. by water flowing through an internal coil in the heat exchanger.
