Title: Abrasive paper for working hides and fine leather - preventing thermal stress and damage due to creasing of hide
Inventor: SELBECK HANS-GUENTER
IPC: B24D11/00
Filed: 1975-04-04
Abstract: Abrasive paper for working leather side of hides and fine leather comprises a coating of abrasive particles which does not cover the paper uniformly, but which is discontinuous, with gaps which form V-shapes with the apex of the V located at the centre of the width of the abrasive coating, and with the arms of the V extending in the direction of working. The abrasive paper may be in the form of a piece attached to abrasive bodies, or as an endless belt which runs over abrasive bodies.

Title: Sectional pipe-rolling roller - with annular eccentric slot on joint of band and bush ends
Inventor: GERASIMENKO ALEXANDR YAKOWLEWI
IPC: B23D79/02
Filed: 1975-05-07
Abstract: The roller comprises a bush with flange and annular band on it with channel on outside. To improve reliability under alternating turning moment, an annular eccentric slot is made on the joint line of the ends of the band and bush, and a ring is pressed into the slot. When alternating turning moment is transmitted from the drive shaft, the annular band tends to shift angularly relative to the bush. The ring acts as a wedge to prevent such a shift occurring.

Title: Stretching equipment drive for wrapping machine - is activated by equipment controlling tension in wrapping foil
Inventor: BRECHEISEN KARL
IPC: B65B13/22
Filed: 1975-07-31
Abstract: The wrapped object is pushed against a foil curtain and the foil forms a loop round the object. The loop is then stretched by a stretching equipment and temporally clamped. The clamped loop is subsequently joined by a welding equipment and thereafter separated from the remaining foil. The stretched moving foil activates a tension measuring equipment including a pressure measuring device with an electric outlet connected to the drive. The tension measuring equipment if fitted with a control device movable by the foil section located between the clamping and stretching equipments. The control device interrupts the action of the pressure measuring device when the tension in the foil is caused by the loop and activates the measuring device when the tension in the foil is caused by the stretching equipment.

Title: Standby battery supply for no-break AC system - uses same transformer for charging and inverter duty
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02J9/06
Filed: 1975-09-08
Abstract: In order to utilise the transformer (8) both as a rectifier transformer when charging the battery (7) and as an output transformer when operating in inverter mode the rectifying unit (5) contains both diodes and thyristors in anti-parallel connection. During charging duty no pulses are supplied to the thyristors and thus they remain in the off state. In a typical installation the load is buffered by a filter (2) which removes system voltage transients when the mains supply is in use, and damps commutation spikes when the inverter is operating. It also acts as an energy store to provide continuity during supply changeover.

Title: Sensors for contactless scanning of moving surfaces - has identical signal suppression and band limitation on output signals compensating for surface irregularities
Inventor: MESCH FRANZ PROF DR ING
IPC: G01B7/34
Filed: 1975-10-03

Title: Marker for people trapped underground etc. - has transmitting oscillator periodically interrupted to save power
Inventor: RICHTSCHEID ANTON DR ING
IPC: H04B1/034
Filed: 1975-12-01
Abstract: A rescue device for people trapped underground, in collapsed buildings, and under avalanches etc., has the power consumption of its transmitter, worn by a person, so that it can operate for about a year with only a normal set of batteries. Persons at ski resorts do not therefore continually have to remember to switch on their transmitters before they venture out. An LC resonant circuit is coupled to the collector circuit of an amplifier (1). The coil (2) in this resonant circuit has a tapping connection back via an RC circuit (4) to the input of the amplifier such that it oscillates. The resonant circuit and RC circuit are designed so that the oscillations stop and restart periodically.
