Title: Sensor unit for automatic alignment of mechanical components - uses stud type pick=up peg in universal joint with ball end fitting hole in workpiece and differential pick=up sensors at top
Inventor: TITTES EBERHARD PROF DR
IPC: G01D5/16
Filed: 1978-10-14
Abstract: The mechanical section of the alignment system comprises a housing(10), retaining an outer sheath(11) with a lower section holding a double gimbal axis universal joint(12) incorporating a "Cardan ring". The joint supports an mechanical pick-up pin(13) with a spherical end(16) which locates in a bore-hole(14) in the workpiece(15). The upper end of the pick-up has a conical shank and a curved cap, the shank being supported in soft foamed flexible material(20). Adjacent to the rim of the conical head are two differential signal sensors(18, 19) which may be field plate devices or photoelements and may be connected in a bridge curcuit, including a potentiometer to adjust the setting of the null point. The upper sections of the pick-up pin are made of soft iron; the geometry is symmetrical so that the device operates equally well in either direction.

Title: Headlight for vehicle with gap between edges - includes reflector and front window to accommodate differential thermal expansion
Inventor: BALS JOSEF
IPC: F21V17/00
Filed: 1978-10-28
Abstract: The headlight, for a vehicle, has a peripheral gap in a radial direction between the edges of the reflector and the frosted front window of the headlight. The width of this gap at two diametrically opposite places on the window is greater than the difference in thermal expansion between reflector and window. The sealing ring consists of a permanently plastic material. The slot that holds the sealing ring between the edges of the reflector and the window has a cross-section chosen so that when the window and the reflector are joined a part of the sealing ring extends into the gap between the edges of the reflector and window. The window and reflector are prevented from moving radially w.r.t. to one another.

Title: Non-homogeneous magnetic field generating device - consists of two loop coils with common axis and interposed dipole
Inventor: KOMENDA WERNER
IPC: H01F7/20
Filed: 1979-02-22

Patent DE-2925177-A1 (DE)
Title: Time delay release circuit for relay for windscreen motor - uses RC delay to first transistor switch on so that second is switched off
Inventor: RAPP FRANZ-JOSEF ING GRAD
IPC: H01H47/18
Filed: 1979-06-22
Abstract: The holding circuit is for a relay. When a start contact is operated a relay operates and remains operated until an RC time constant circuit has charged up to switch it off. The design stabilises the operate time and minimises the variations due to temp. and supply voltage. The system is intended for windscreen washer motor control in vehicles. A start contact (1) is operated and the second transitor (5) conducts to allow the relay (2) to operate. The relay contact (3) holds and operates the required appts. i.e. connects battery (+U) to the washer pump motor. The RC circuit capacitor (7) charges through a resistor (6) and is in the base circuit of the first transistor (4). When charged it switches on the first transistor (4) and the collector current flowing drops the base voltage of the second transistor (5) so that it switches off so de-energising the relay (2), and in turn the relay contact (3) opens. Operational stability is achieved by the emitter coupling of the two transistors by a resistor (11) and the selection of collector resistors where used.

Patent DE-2937208-A1 (DE)
Title: Lock saw for rubber material - with support shoe and wedge for adjusting free passage
Inventor: WEISHAAR FRANZ
IPC: B23D29/00
Filed: 1979-09-14
Abstract: A cutting device for rubber sheets and plates is a manual lock saw with a support column behind the saw blade, carrying a support shoe with a flat base. Its run-up surface is inclined to lead the rubber sheet up to the saw blade and has an adjustable wedge part to alter the free passage for the material. The saw blade is ground in knife fashion in the toothed area. This saves the use of a knife blade which is much more time consuming, e.g. when used to trim the damaged edges of conveyor belts. A ground saw blade readily cuts rubber.

Abstract: Pairs of blister packs arranged in mirror image form are produced from a continuously moving packaging band. Perforated or slotted break lines are worked into the band at equal distances from each other and between the blister cells with the longitudinal edges of the band being partially cut. The band is then cut along the length of the break lines into at least a pair of length strips of blister packs during which the remaining sections of the length edges are separated. Finally the pairs of the length strips are separated along the break lines into separate blister packs lying parallel next to each other which are then stacked in pairs and in mirror form one above the other.

Abstract: The deep boring machine for machining the insides of large pipes has a tool carrier (12,34) at opposite ends of a bed (10) sliding along longitudinal guides. Between them are two sliding tool guides (70,72) and at the centre a work holder (18). Each tool carrier has a drive unit and two boring tools (30,32,40,42) so that two pipes can be simultaneously machined, then exchanged for two further pipes. The work holder has a rotating block which supports all four pipes and which is operated to change them over. The four pipes are gripped by the work holder while held at four locations forming the corners of a square and axis of rotation of the holder is at the centre of this square. It rotates inside a ring of rollers, and uses a gripping mechanism operated manually, magnetically or hydraulically. The tool guides combine the flow of cooling and lubricating fluids.

Title: Remote operated flanged joint locking mechanism - uses roller chain carrying tensioning screw and supported inside circular leaf spring inside housing
Inventor: ANDELFINGER CLAUS DR
IPC: F16L23/04
Filed: 1980-07-09
Abstract: The device for clamping two flanges together consists of a chain with rollers (12) with sloping sides, which retain between them the two flanges which also have sloping sides. The design ensures that release of the flanges is faultless when controlled by a remote operated mechanism. The chain is enclosed by a ring (18) retained between two rings which also fit over the two flanges. The chain itself is tensioned and released by a tensioning screw (28) which projects at both ends through openings (36,38) in the enclosing ring. The chain links are attached to a ring-shaped leaf spring (20), which fits round the outside of the chain. Thus the chain is supported without kinking. The tensioning screw is supported by a block (30) forming a central part between two spindles for one of the chain rollers.

Title: Electron microscope image amplifier - uses angled fibre optic plate in beam connected to amplifier and optical viewer
Inventor: GUETTER ERNST DR
IPC: H01J37/22
Filed: 1980-08-16
Abstract: The amplification system (15) is attached to the microscope in the region of the final image lens (10) and image screen (12). The centre of the final image can be observed by eye (14) when enlarged by an optical lens system (13). The main amplifying system consists of a fibre optic plate (17) with a high aperture and having an oblique surface (16) at the input side forming angle of 45 degrees to the axis of the corpuscular beam path. Where the beam strikes the fibre optic plate, a high resolution reflex optical screen couples the beam to an image intensifier (18) whose output can be observed via an optical viewer (13') by the naked eye (14'). The system (15) is so constructed that it can be swung into the beam path of the microscope, and allows a larger section of image to be observed, with excellent contrast, while keeping interference with the beam itself to a minimum.
