Title: Linear push-button switch - has hollow support body as prismatic housing with inner contact slider with rectangular recesses
Inventor: VESPERINAS ROY ANTONIO
IPC: H01H15/06
Filed: 1975-11-05
Abstract: The linear push-button switch has a housing (8) forming a prismatic hollow support body, whose one side is open and whose other side is closed by a thin-wall, flat lid (6). Inside the housing moves a contact slider (21) whose part moving in the housing has recesses (22) of rectangular cross section, in which are mounted the moving contact (4). The latter have each an upper eyelet (24), slid over the connecting pin (11), protruding from the slider, thus forming a connection between the moving contact and the slider. The eyelet surrounding the connecting pin is extended on both sides into two concave arcs (25), forming convex arcs (27, 28) via a horizontal member (26).

Title: Accidental drop safety device for roller shutter - has oscillating end slat connected element checked at excessive falling speed
Inventor: BUTZBACH ARNOLD
IPC: E05D13/00
Filed: 1975-11-27
Abstract: The safety device for roller shutters, esp. in front of large openings, prevents them from moving downwards of their own accord, which could cause damage or mutilation. The end slat (2) is connected to an element (17), which can pivot. This acts in conjunction with a slat (12, 13) parallel to the end slat's track, made up from a number of attachments (15, 16) with intervening spaces (14). With normal lowering of the shutter these attachments set the element in an oscillating motion in and out of the spaces, but excessively rapid downward movement causes the nearest attachment to block the outward swing and thus prevent any further drop.
Patent DE-2553832-A1 (DE)
Title: Filing and/or buffing fingernails in one direction - using buffing paste or powder contg. kieselguhr and stearic acid
Inventor: TSUKAMOTO SAKICHI
IPC: A45D29/04
Filed: 1975-11-29
Abstract: Finger-nails are filed and/or buffed with a nail-file having a rough and a smooth abrasive surface, for pre- and after-buffing. Novelty consists in filing and/or buffing in repeated movements, in only one direction. At least pre- and/or after-buffing takes place in the presence of a buffing paste and/or buffing powder. Pre-buffing pref. takes place in the presence of buffing paste and after-buffing in the presence of buffing powder. Paste consists of a mixt. of kieselguhr, glycerol, propylene glycol, stearic acid, nutrient colour and distilled water. Powder consists of a mixt. of kieselguhr, paraffin, beeswax, lanolin, stearic acid and nutrient colour. On filing in one direction, nail parings and paste or powder residues are not moved back to nail surface. Nail smoothness is improved. Buffing accelerates capillary flow in nail bed.

Title: Thickener to recover solids from slurries - having conical section with lower part in portioned chambers
Inventor: SCHNEIDER HEINRICH
IPC: B01D21/00
Filed: 1975-12-24
Abstract: Thickener has an upper thickening region with a central inlet with tangential direction for the incoming slurry. Around its edge is an overflow weir for the clarified liquor. In the lower thickening region are run off branches for the concd. slurry. The thickener is a single round vessel the walls of which are conically inclined at an angle between 60 and 80 degrees, pref. 65-75 degrees. These open out towards the upper thickening zone. The lower zone has a series of internal partitions which divide it into individual compartments open towards the upper thickening zone. Each has a separate run off from the concd. slurry. Used in mineral prepn., esp. coal, esp. for the recovery of coal from a froth flotation operation. The yse of thickeners with mechanical scavengers for the solids is known. However from the nature of the process hould a build up occur during the operation, the device will seize. Once this happens the whole unit has to be dug out and cleaned. The resulting concentrate can contain at max. 500-600 g/l. and is thus 50-40% water. This increases the transport cose. The thickener described gives a more concd. slurry and avoids the seizure problem.

Title: Lubrication control for castor - has sealing plug with lubricating grooves pushed into axle
Inventor: ERTLE KARL ING GRAD
IPC: B60B33/00
Filed: 1975-09-27

Patent DE-2603658-A1 (DE)
Title: Shutter with simple flash control - moving blocking cam into path of shutter drive lever for synchronous action
Inventor: HUBER LEONHARD
IPC: G03B9/24
Filed: 1976-01-30
Abstract: The shutter opening drive is fitted with a delay mechanism to control the exposure time as well as a movable stop to regulate the preset aperture. When a flash gun is fitted a special arm displaces the delay mechanism and replaces it with a control arm linked to the distance setting cam. Electric control contacts for the flash synchronisation are also fitted to the special arm for a simple layout. The flash contacts are thus only used when the gun is fitted, thereby reducing contact wear. Two shutter lamellae (1,2) cover the opening (3). They have a common pivot (4). Both have slots (5,6). A rod (7), driven by a lever (8), penetrates both slots.

Title: Independent vehicle wheel suspension - has carrier with bearings for wheel and transverse guide rods
Inventor: WUERTH GUSTAV DR
IPC: B60G3/01
Filed: 1976-09-10
Abstract: An independent wheel suspension operative in the vertical direction and in the direction of travel has a wheel carrier comprising a wheel bearing with cross-support which terminates above and below with an operative guide axle. The front bearings of the transverse guide arms are mounted on these guide axles and can be displaced longitudinally against the action of spring located between the bearing and the end of the guide axle. Should a force in the direction of motion be exerted over the wheel bearing then the cross-support can deflect in this direction. The bearing remains fixed in its position through the upper and lower transverse guide arms.

Title: Transceiver for remote control of toy car - uses regenerative detector circuit energised by radio noise
Inventor: ISHIMOTO ZENICHI
IPC: A63H30/04
Filed: 1976-10-13
Abstract: A toy motor care is remotely controlled by a transmitter (10) powered by a battery (12) with a generator (14) and antenna (16) which transmits a signal, on a frequency of 27 MHz. The receiver (20) installed in the car is powered by the battery (22) and consists of an antenna (24), a super-regenerative detector circuit (26) an amplifier (28) a relay (30) and a motor (32). The super-regenerative detector circuit (26) generates a noise signal which is attenuated when the 27 MHz signal is received. The relay (30) is in one of two positions when receiving the noise signal and in the other position when acted on by a spring. By a combination of these effects it is possible to control the toy car so tha it moves either forwards or backwards or in straight or curved lines.

Title: Filling mining cavities - using dil. aq. hydraulic binder or mortar suspension admixed with compsn. contg. solidification accelerator and thixotropic component
Inventor: MIKOTEIT JOHANNES-FRANZ
IPC: E21F15/08
Filed: 1976-10-30
Abstract: Process comprises conveying a dil. aq. suspension of hydraulic binder or hydraulically setting very fine mortar through pipe- or hose-conduits over large distances from an opt. underground mixing and pumping station, as far as the underground area of application. An activating compsn. is admixed to the suspension, near the cavities to be filled. Directly after leaving the conduit, the suspension is compacted to a thioxtropic compsn. and the solidification of the hydraulic binder or of the hydraulically solidifying mortar is accelerated. Shortly after onset of thixotropy, e.g. within seconds, the material starts to solidify to an artificial stone, which fills the cavity completely.
