Title: Binding wire spiral prodn. for blocks of paper sheets - includes stages for dividing, perforating and combining sheet stack, after which wire spiral is inserted
Inventor: FABRIG PAUL
IPC: B42B5/12
Filed: 1977-07-27
Abstract: The prodn. method for blocks of paper sheets or similar materials bound together by wire spirals includes the following processing stages:- the stacks of paper sheets of multiple block width are divided into part stacks, and are then holed along one stack edge; the part stacks are then combined into one stack and cut into blocks. Each block is then lined up and a wire spiral is then inserted. The processing track for the stack or for the blocks extends only in the one plane which lies parallel to a front surface of the stack defined by a short side edge and the stack height.

Title: Powdery reactant metering system - esp. for feeding para-formaldehyde powder for the denitration of radioactive waste soln.
Inventor: GATTYS FRANZ JOSEF
IPC: G21F9/06
Filed: 1978-05-12
Abstract: A device for metering a reactant into a reactor, esp. for feeding paraformaldehyde powder for the denitration of radioactive waste solns., is described in the parent patent (2807324). A mechanical feeder supplies the reactant through a spring-loaded flap to the inlet cone (tapered down to 0.5) of a blast nozzle. Compressed air passes through the nozzle and takes the reactant through the divergent outlet to the reactor. The result is an even distribution of even very small flow rates of reactant. The blow nozzle protects the feed section against incrustation from moisture in the reactor.

Title: Machine for cleaning long lengths of pipe - has oscillating platform to impart hammer blows to cleaning rod
Inventor: BIBER JOHANN
IPC: F28G15/04
Filed: 1978-06-08

Title: Monolithic integrated semiconductor reference element - has surface silicon di:oxide layer with windows for emitter and base contacts whose metallising reaches up to pn-junction
Inventor: CONZELMANN GERHARD DIPL PHYS
IPC: H01L29/06
Filed: 1978-06-23

The integrated element has a silicon dioxide film (4) on the semiconductor surface, with windows for the emitter and base contacts. The contact metal film (5) of the base is drawn so far over the insulation silicon dioxide film as to cover the edge (7) of the pn-junction, emerging on the semiconductor surface. Preferably the emitter surrounds the base as a ring, partly diffused into the same. The base contact may be annular and in such instance the emitter is eccentric to the base contact. Alternatively, the base contact may be elliptic and/or the diffused emitter may be of elliptic configuration.
Patent DE-2830591-A1 (DE)
Title: Proximity control of rail-round transporter - with rail-bound control trolley unaffected by rocking movements
Inventor: SCHEICH DIETER
IPC: B61L3/02
Filed: 1978-07-12
Abstract: A control system uses a control trolley which runs on the same rails as suspended or aerial transporters running on tracks on the ground. The trolley includes magnetic field transmitters which can actuate the feeder drives of a line of silos to feed the transporter in turn. It includes also a magnetic field sensitive switch which stops the transporter by the proximity of a magnetic field transporter over the discharge station. The transporter takes the trolley along through a pin between a fork of the trolley so that rocking of the transporter does not alter the air gaps between magnetic field transmitters and pickups. The transmitters and pickups are housed in plastic cases, embedded in silicone rubber. This ensures a contactless proximity control which is not affected by irregular movements of the transporter.
Patent DE-2831446-A1 (DE)
Title: Sensory stimulation substitution system for blind persons - has stimulation generator with centre tapping of transformer connected to battery terminal via switch
Inventor: SCHWARZ SIEGFRIED
IPC: G09B21/00
Filed: 1978-07-18
Abstract: The sensory stimulation substitution system produces electrical impulses transmitted via electrodes to the skin to cause a sensation. The strength of the latter is affected by modulation of the amplitude, pulse duration, interval and/or change-over frequency of the current by light sensors. The generator is supplied by a battery (1), and the stepped-up voltage necessary for stimulation is obtained by connecting the centre tapping (4) of the transformer via a switch (2) with one battery terminal. The outer terminals (5, 6) of the transformer are connected via a change-over switch (3) to the other pole, switch operation being effected automatically by change of direction of the transformer secondary (7) so that no coupling condensers separate from the electrodes are necessary.

Title: Track information transmission system - comprises additional receiver on vehicle after main one to provide internal signals for speedometer
Inventor: PUTZE KARL DIPL ING
IPC: B61L3/00
Filed: 1978-12-15
Abstract: The equipment transmits track information to a vehicle such as a tram, trolleybus etc., from a stationary emitter via a receiver on the vehicle to a processing unit, the vehicle travelling in a predetermined direction. Behind the receiver on the vehicle in the travel direction is an additional receiver. The data received by both receivers from the emitter is passed by a monitoring circuit to the processing unit when data received by them is identical.
