Title: Abrasive band copying machine tool - has pattern and cam controlling tool position relative to spindle
Inventor: WILLEMIN ANDRE
IPC: G04D3/00
Filed: 1975-10-31
Abstract: The machine rool (14) has a copying mechanism which incorporates a self-rotating pattern unit synchronously driven with a spindle (2) carrying the workpiece (6) to be machined. The pattern, through its rotation, controls the relative position between the spindle (2) and the machining tool in relation to the clearance between them. Either a tool retaining holder (10) or a spindle (2) retaining holder (3) is swivelably located on the machine frame (1) in such a way that a swivel movement is executed around an axis (4) which is normal to the spindle axis, and meets it at the spindle end. The position changes of the machine component (3) swivelably connected to the machine frame (1) are effected by means of a cam (19) which rotates synchronously with the spindle (2).

Title: Pneumatic hammer freeing powder material from container wall - comprises sprung cylinder compressed by air supply and released by valve to hit external wall
Inventor: KROEGER DIETRICH
IPC: B08B7/02
Filed: 1975-11-05
Abstract: The rapid acting pneumatic hammer is for removing powder material or dust from the inside walls of containers eg. bunkers especially when slightly damp. The hammer applies a sharp blow to the outside wall. The hammer consists of a cylinder (1) with a piston (2) held by a spring (3) against the impact plate (7). A valve (5) allows high pressure air to flow through the pipe (12) to the underside of the piston (2). The air supply is then shut off by an external control valve causing the valve (5) to lift off its seat. This allows air to flow back from the underside of the piston (2) to the upper surface via the pipe (12) and exert a force on the piston which is driven against the impact plate (7).

Title: Mine railway conveyor centre buffer coupling - has housing linked to rod adjustable against spring action in frame
Inventor: MEISSEL PETER DR
IPC: B61G3/00
Filed: 1975-07-12
Abstract: The coupling is for mine rail track guided conveyor wagons with a coupling housing in the form of a central buffer, with buffer end plate and coupling jaw swivelling out from this. It is designed to stand up to severe jolting in shunting and similar operations in severe conditions. The coupling housing is attached to a coupling rod (21) which is axially adjustable and swivelable in a frame (22) against the action of rubber springs (23). Any jolting that occurs is absorbed and damage to couplings prevented despite the heavy weight of the loaded conveyors.

Title: Clothes dryer with hot air current - with air outlet slots or nozzles beneath which clothes are suspended
Inventor: SCHNAUSE ROLF
IPC: D06F58/14
Filed: 1976-01-10
Abstract: Clothes drier operates with a hot air current which is forced into an air outlet channel in the lower surface of which are air outlet slot(s) or nozzle(s) beneath which are rod(s) for hanging the clothes. Pref the air current leaving via the slots or nozzles is deflected obliquely in a direction towards the clothes, and the reaction component of the deflected air current is utilised for pivot movement of the air outlet channel, pref. by alternately closing and opening the respective air outlet slots or nozzles. This may be achieved by means of a flat slide valve which is reciprocated by an electromagnet, or the air outlet channel may be reciprocated by levers or cams driven by the fan motor with reduction gears. Drying time is reduced.

Title: Monitor for pathological deviations in cardiac activity voltage - has two delay circuits and non-transitory store released to record cardiac activity voltage signal
Inventor: MAASS JOACHIM A
IPC: A61B5/336
Filed: 1976-06-18
Abstract: Appts. for recording the time progression of signals derived from cardiac activity voltage comprises a monitor which detects pathological deviations in cardiac activity voltage. The signals are transmitted to a first delay circuit of which the delay time is equal to a heart beat period and which is connected to a non-transitory store. This is connected to a second delay circuit in which a given number of measured values can be stored by a device for measuring the heart beat periods. When triggered by a monitor signal, the store can be released for recording the cardiac activity voltage signal transmitted via the first delay circuit, the values fixed in the second delay circuit prior to triggering, and a number of values transmitted via the second delay circuit and fixed after triggering. Diagnostic relevance of the recording is increased, and storage space requirements are reduced.

Patent DE-2640395-A1 (DE)
Inventor: ZELLER JOHANN
IPC: B29C45/23
Filed: 1976-09-08
Abstract: The injection-moulding machine suitable in particular for injection moulding plastic has an injection head (1) with a feed channel (2) which can be closed by a slide valve (6). To open the feed channel (2) during operation, the slide head has rollers (14) which, when running on an inclined surface, push the slide against a spring (8) and align a through-flow channel (7) with the feed channel (2). To clean the injection head, for example during material exchange or other maintenance work, the feed channel (2) can be opened by rotating the slide through 180 DEG , effecting an alignment of a second through-flow channel (15) with the feed channel (2). The advantages of the simple slide operation are combined with those of a straight, low-resistance flow path. <IMAGE>

Title: Line protective circuit breaker with double interruption - has contact bridge contacting two inner quenching baffles in its max. breaking path to transfer directly arc points
Inventor: WIRZ BERNHARD
IPC: H01H9/46
Filed: 1977-01-04
Abstract: The protective circuit breaker with double interruption has standardised narrow dimensions and a quenching chamber region for each interrupting position. The light arc moving parts form a circular arc path from the interrupting positions along the outer walls on the narrow sides, while being connected conductively to the outer quenching baffles. These parts guide both light arcs into the quenching chamber, when the contact bridge moves. When the latter has reached its maximum breaking path, the two inner quenching baffles are contacted by the bridge with the result that the light arc bottom points have a direct transition to the baffles. The contact points between the bridge and the baffles are preferably outside the zone of the light arc bottom points.

Title: Control of vehicle position within defined field - is esp. for automated agricultural applications by using reflectors mounted along opposite boundaries of field
Inventor: VORNKAHL WOLFGANG DR ING
IPC: G05D1/02
Filed: 1977-02-05
Abstract: The position of a powered vehicle (10) within a defined field (5) is determined by positioning suitable transmitters (6, 7) at two corners of the field and using a receiver mounted on the vehicle with suitable electronics (11) to determine the relative signal strengths of the two signals to determine and display (12) the vehicle position. Alternatively, the two transmitters (6, 7) can be mounted on the vehicle itself and reflectors (13, 14) used at the corners of the field. In the case of a field which is being repeatedly transversed by a vehicle (10), rows of reflectors (13', 14') can be mounted along opposite boundaries of the field and backwards and forwards signals transmitted from the vehicle by IR and ultrasonic transmitters.
