Title: Tooth-brush with time switch - automatically actuated by temp. of mouth and/or hand for signal transmission
Inventor: SCHELLER ULRICH DR
IPC: A46B15/00
Filed: 1979-05-10
Abstract: Cleaning of teeth should last at least 60 seconds for effective protection against decay etc. A time sensor is therefore provided in the toothbrush, which generates a signal after an effective cleaning period. The sensor responds to the temp. of the mouth and/or a hand for actuation of its operation. Pref. a plate (2) with a thermo-colour field is secured to the toothbrush, providing illumination in dependence of its warming up, i.e. the cleaning period. This plate may be secured to the head (1) containing the bristles. Alternately, it is secured to the inside of the handle. The sensor contains a thermostat, a transistor and a battery, all housed in a part of the toothbrush. It may generate an optical signal under the thermostat control. The battery may be coupled to a solar energy powered generator.

Title: Fuel saving accelerator pedal for car - has increased spring resistance above optimum throttle setting
Inventor: BROSS RAINER HENNING
IPC: B60K26/02
Filed: 1979-06-11
Abstract: The fuel saving fitting is designed for use on a car. It has a block positioned behind the accelerator pedal on which the driver is able to rest his foot. The layout provides the most comfortable position when the optimum throttle setting is reached, with increasing spring resistance for higher settings. The device does not alter the throttle linkage and can be fitted to most cars. It does not prevent temporary increases in throttle setting for overtaking, and is comfortable also as lower settings.

Title: Tube mill with two grinding chambers - has chambers completely separated by partition for simultaneous grinding of two different materials
IPC: B02C17/06
Filed: 1979-07-18
Abstract: The tube mill has a shell with abrasion-resistant linings selected to suit the behaviour of two different materials processed simultaneously. The two chambers are separated by a gas tight partition. To each side of the partition at some distance perforated partitions are provided creating discharge chambers with several discharge openings. The discharge chambers are stationary and surround the rotating mill which is seated by two neck parts serving as material charge openings served by chutes. The ground material leaves the mill through perforated partitions and discharge openings into the discharge chambers and from there through sluice mechanisms into the open, while gases and dust are exhausted through connections with airtight partition at the top of the discharge chamber.

Patent DE-2948722-A1 (DE)
Title: Pole arrangement for improving synchronous motor starting - has screened and unscreened groups of poles each with own reference flux pole
Inventor: WEAVER ROBERT FRANCIS
IPC: H02K21/12
Filed: 1979-12-04
Abstract: The pole arrangement uses screens to produce a group of screened poles (TS, BS) and a group of unscreened poles (TU, BU) for a given number of stator poles. A reference pole(60, 62) is selected from each group. The flux phase difference between the reference pole and the individual poles in its group is determined and converted into a mechanical angle. The poles are arranged w.r.t. one another in accordance with this mechanical angle. The flux phase difference is determined by comparing with a shared flux source. The shared flux source is a core belonging to the field winding. The flux difference is converted into a mechanical angle using the formula E=2 dn/N where E is the correction angle, dn is the phase difference in electrical angle and N is the total no. of poles(rotor and stator).
Patent DE-3000099-A1 (DE)
Title: Precision beet topping mechanism - has flail chopper guided vertically by support plate tilting it rearwards
Inventor: BROCKMANN FRIEDRICH
IPC: A01D23/02
Filed: 1980-01-03
Abstract: The beet-topping mechanism has a flail-type chopper movable up and down, which is guided by a support plate, so as to tilt it rearwards. The plate causes the chopper to follow the contours of the ground, and also guides the leaves towards it in the lateral direction. It further causes the chopper to move in the opposite direction, when the digging implement tilts forward. The mechanism can be mounted on a parallelogram linkage, so as to adjust automatically the top thickness to match the amount, for which the beet protrudes from the ground.

The upper part houses a bellows (17) against which the fluid can act, extending it when expanded, lifting an arm (25) on top, which tilts the swinging arm. A return spring (23) fits around a piston (19) enclosing the top of the bellows.

Title: Fire barrier for tubes passing through partitions - consists of gate-like element slidable in gap between tube ends to cut off flow of working medium
Inventor: RITZ OTTO ING GRAD
IPC: A62C2/18
Filed: 1980-03-15
Abstract: The device prevents spreading of fire from one room into another, the working medium, such as compressed air acting as a carrier. The passage in the partition has a double-skinned frame (4) where plates (8a) and (8b) are fitted at a distance to create chamber (9).

Title: Coal solvent contains sec. alcohol for hydrogen transfer - and coal-tar- or -pitch-distillate
Inventor: STADELHOFER JUERGEN DIPL CHEM
IPC: C10G1/04
Filed: 1980-04-03
Abstract: In a process for dissolving coal and similar materials at high temp. and pressure the solvent is a mixt. of (a) aromatic distillates (pref. mean b.pt., 350 deg. C) from the refining of coal-tar or pitch, opt. with added oil-derived aromatic fractions; and (b) a sec. alcohol, pref. isopropanol, as H transfer agent. The ratio coal:aromatic oil is pref. 1:5- 2:1, and coal:alcohol is 1:1-20:1. As a first step in the prepn. of substitute oil fractions from coal. The secondary alcohol makes the use of H2 (e.g. to make a hydrogenated aromatic H carrier) unnecessary. Small amts. of alcohol give large increases in solvent power, e.g. 15 pts. of isopropanol added to 40 pts. coal and 60 pts. pitch distillate increase the amt. of extract from coal at 350 deg. C by 10%.

Title: Top roller mounting for spinning frame drafting assembly - has spring-loaded saddle holding cantilevered roller
Inventor: GLOCK ALFRED ING GRAD
IPC: D01H5/56
Filed: 1980-07-02
Abstract: The top drafting rollers of a spinning frame are individually mounted in cantilever fashion from a bracket attached to a spring-loaded saddle, such that the mid-point of the roller is in line with the longitudinal axis of the saddle-arm. The roller bearing is carried in the vertical leg of the inverted-L-shaped bracket, or it may consist of a pair of bearings mounted in opposite arms of an inverted-U-shaped bracket. The rollers may have a stub axle at the free end which, in conjunction with the axle at the bearing side, forms a seat for an upper apron cage. This construction inhibits the accumulation of fly closely adjacent the roller, and facilitates removal of roller laps without dismounting the roller.

Title: Floating caliper vehicle disc brake - has pad caliper guided on carrier bolts via eccentric resilient bushes pressing caliper against carrier in mounted position
Inventor: FRIGGER HEINZ DIPL ING
IPC: F16D65/54
Filed: 1980-08-29
Abstract: The motor vehicle disc (2) brake assembly comprises a carrier (1) secured to the vehicle and a floating caliper (10) at least partly guided via one or more bolts (11) on the carrier.
