Title: Alarm clock with weekday alarm selector - uses weekday disc and is fitted with alarm selector switch for each day
Inventor: HETTICH HUGO
IPC: G04C21/16
Filed: 1974-05-14
Abstract: The weekday disc is driven from the clock mechanism via spring means and has an ON-OFF alarm selector switch for each day of the week.

Inventor: MAIER HERMANN DIPL ING
IPC: E01C7/35
Filed: 1974-05-31
Abstract: In mfg. concrete surfaces, a layer of lean concrete is applied to the sub-structure or foundation and, after the cracks and fissures have formed, a layer of epoxy-resin mortar is applied with a consistency such that the cracks in the surface of the lean concrete are filled.

Title: Phototransistor DC component suppressor - used when phototransistor is exposed to constant and varying illumination, has two resistors and capacitor
Inventor: KRAUSE GERHARD
IPC: G01J1/44
Filed: 1974-07-04
Abstract: A first resistor is inserted into the transistor emitter circuit and the collector-emitter path of at least one further transistor is in parallel with the phototransistor base-emitter path and the first resistor.

Title: Fast coupling circuit between fast complementary MIS chips - has output stage with source follower and inverter, and input stage with drive transistor
Inventor: POMPER MICHAEL DIPL ING
IPC: H03K5/003
Filed: 1974-09-10
Abstract: The fast coupling circuit transfers signals between two fast complementary MIS chips. The output stage (12) of the first chip (1) contains a source follower and an inverter. The inverter consists of two complementary enriched transistors, and the source follower consists of a depletion transistor. The transmission line (3) between chips is terminated in an impedance (4) and is connected to the source follower. A depletion transistor in the second chip's (2) input stage (13) is controlled by the transmitted signal. The advantage of the coupling circuit lies not only in its speed by also in its requiring no input stage clocking because it can be designed with a sufficiently high gain.

Title: Gearbox for machines in work transfer system - has auxiliary input for changing phase of output
Inventor: TANDLER SIEGFRIED F
IPC: F16H1/46

Title: Hydropneumatic shock absorber with two pneumatic chambers - has floating piston to avoid excessive gas pressure when fully compressed
Inventor: KATSUMORI TEIJI
IPC: F16F9/06
Filed: 1975-04-30
Abstract: A hydro-pneumatic shock absorber consists of a cylinder (1) a piston rod (2) and a piston assembly (16). A floating piston (5) divides the shock absorber into a hydraulic and pneumatic section. A hydraulic chamber is located on either side of the piston assembly (6) and they are connected with one another by throttle elements (6a-6c) inside piston (6). The pneumatic chambers (C, D) are formed by the space between the floating piston (5) and the cylinder end, and by a concentric tube (7) which forms a ring chamber on the outside of the cylinder. The two communicating pneumatic chambers provide thus a large enough gas volume to prevent excessive pressure when the shock absorber is fully compressed.

Title: Induction heating coil for zone melting semiconductors - has recesses inside for spike to prevent latter causing short circuit
Inventor: RIEDL ERICH
IPC: H05B6/36
Filed: 1975-06-18
Abstract: The inductive he ating coil, for melting given regions of a semiconductor bar (about 40mm dia.) without using a crucible, is constructed in two semi-circular halves which bolt around the semiconductor bar and melt a waist into it. In such a process 'spikes' (7) are often formed at the waisted region. These spikes can touch the induction coil and cause a short circuit which stops the process. The new arrangement prevents this short circuit by having a cut-out portion (5) in the inside circumference of the coil to allow the spike to form without danger of shorting.

Title: Heating element with flattened outer tube - contains insulating thermal conductor and grille of resistance material
Inventor: EICHENAUER FRITZ
IPC: H05B3/48
Filed: 1975-07-30
Abstract: The heating element consists of a flattened outer tube containing electrically-insulating, thermally-conducting material surrounding the resistance element. To increase the area available for thermal conduction the resistance element is constructed as a grille or mesh. The resistance grille (3) consists of a log strip embedded in the insulating material (4) inside the outer tube (2). The ends of the resistance strip are connected to terminals that project beyond the ends of the outer tube. The advantage lies in breaking away from the tradition round shape of the tube.
