Patent DE-2941871-A1 (DE)
Inventor: TEUFELSBERGER VOLKHARD DIPL IN
IPC: H02K17/14
Filed: 1979-10-16
Abstract: The invention relates to a winding for reversible-pole electrical machines, especially synchronous machines, having numbers of poles close to one another, such as 12:14, for example. Until now, it has been normal to equip such machines with two separate windings. However, this resulted in an increased space requirement and thus in an enlargement of the machine diameter. The object of the invention is to create a winding which can be switched over economically between both rotation speeds. The winding according to the invention has the features that it is a six-zone winding having at least two, symmetrical, parallel branches. These parallel branches have coil groups which are electrically identical and which, in operation with the one number of pole pairs in the branches, have the same flow direction, and in operation with the other number of pole pairs in the branches, have different flow directions. In consequence, it is possible to change the allocation to the branches of these coil groups in order to obtain a coil group which already exists in the same manner in the branch.

Title: Exhaust afterburner for IC engine - has longitudinal pockets for air and gas to cool exhaust before discharge
Inventor: LEISTRITZ HANS KARL DR
IPC: F02B75/02
Filed: 1979-11-02
Abstract: The reactor has an aluminium casing with concentric and radial internal partitions. Ceramic plates are placed round certain of these. Exhaust gas enters a central tube which takes it to a main combustion chamber. Secondary air is entrained at the base of the tube. There is an annular afterburner chamber round the inlet tube so that it preheats the entering mixture. Header chambers below the afterburner discharge the burnt gases into perforated tubes within pockets in the casing. These alternate with cooling air pockets with a high thermal transfer between the sets of pockets. This cools the exhaust before it is discharged.
Patent DE-2944231-A1 (DE)
Title: Variable-frequency clock generator for IC engine ignition - uses counter to switch tuning circuits through to pulse generator
Inventor: STILLER ARMIN
IPC: H03K3/72
Filed: 1979-11-02
Abstract: The clock generator has a pulse generator (1) connected to tuning circuits (5-13) that determine the frequency of its pulses. Each tuning circuit can be connected independently of the others to the pulse generator via a counter (3). The counter is moved on to its next stage by the output of the pulse generator. When the last place of the counter is reached no tuning circuit is connected to the pulse generator. The tuning circuits are designed to give the same resolution for different time intervals. The tuning circuits consist of resistors sharing the same capacitor. The resistors are connected to the outputs of the counter. The clock generator is intended for setting the ignition point of an i.c engine.

Title: Compost making combination - with motorised shredder and extensible cowl
IPC: B02C18/22
Filed: 1979-12-04
Abstract: A set of apparatus for the preparation of compost from domestic and garden rubbish consists of a wheeled motorised shredder and a compost cowl. The shredder includes a revolving cutter arm which is coupled by friction to a flywheel and a drive shaft. Centrifugal action projects the shredded refuse out of an opening. The compost cowl is a sheet metal structure in the shape of an inverted U with an opening in front and a hinged rear. The latter can be lifted up as filling proceeds, and is extended by a plastic foil as the cowl is pulled forward. This forms a useful combination which can convert most refuse without effort into compost.

Title: Knot-tightening and trimming device for tying-in machine - rolls knot between resilient jaws before cropping ends
Inventor: KOENIG DIETER
IPC: D03J1/18
Filed: 1979-12-17
Abstract: Between the knotter and the pin which draws the knot out of the knotter of a tying-in machine for joining two warps is a retarding device comprising a fixed jaw and a resiliently-movable jaw between which the knot is drawn by the withdrawal pin, thereby rolling and tightening it. Adjacent the yarn path behind the retarding jaws is a cutter which trims the tails close to the knot, and a waste chute for removing the trimmings. This arrangement facilitates the production, in all types of yarn, a strong, neat knot which does not require hand-trimming.

Title: Regulation of tape recorder motor to give constant tape speed - has photoelectric spool speed sensing to generate control of motor
Inventor: STEIPE LEO A DR
IPC: G11B15/54
Filed: 1980-01-10
Abstract: A speed control system for a magnetic tape cassette recorder utilises photoelectric sensing to maintain a constant tape speed. The winding spool capstans carry two signal generating discs (2A, 3A) that are sensed by non contact photoelectric sensors (8) to produce signals proportional to speed. The signals are processed through a control stage (7) to generate a command to vary the speed of the motor (5) to maintain a constant tape speed, as the diameter of the tape spools change.

Title: Windscreen wiper speed control for vehicle - uses signal from moisture sensor to adjust operating interval and control on-off switching
Inventor: SCHMIDT DIETRICH
IPC: B60S1/08
Filed: 1980-01-17
Abstract: The control uses a moisture sensor (11) coupled to a regulator (12) for the drive motor (6) for the windscreen wipers. The regulator (12) is also coupled to a setting element (13) for the operating interval of the wipers and to an ON-OFF switch (14) for the wipers. The wiper blade (5) fits behind a cowling (8) extending adjacent the windscreen surface (21) in one end position with a vertical duct communicating with the channel defined by the cowling (8) and the windscreen (21) containing the moisture sensor. The control allows the windscreen to be kept clear when the rainfall is very heavy and when it is snowing and prevents operation of the wipers when the windscreen is dry.

Title: Drinking water filter - with filter element including acidulating and biocidal substances
Inventor: HENGST BERND ING GRAD
IPC: B01J49/60
Filed: 1980-01-18
Abstract: A filter, esp. for the purificn. of drinking water, has in the fluid path between an inlet and an outlet a filter chamber contg. a filtering material.

Title: Digitally controlled analogue signal generating system - generates analog signals of varying frequency from digital values by adjustment of fundamental and read out frequencies
Inventor: GERGES ANDRE DIPL ING
IPC: G06F1/03
Filed: 1980-03-17
Abstract: The appts. is used for the transmission of variable frequency signals over short wave communications links as digital signals and the generation of the appropriate analog. The appts. is used for storing and reading the individual values by means of a fixed time interval read out and a digital to analog converter. To generate analog signals (A) of frequency fn which are a multiple of a base frequency df, equidistant values are stored. The number of such values is proportional to the quotient of the read-out frequency (T) and the base frequency. The values are read out of the store (SP) sequentially. The reduction in required storage size is considerable, and is proportional to a factor dependent on the base frequency. For example, a reduction from 14400 places to 240 can be achieved.

Title: EM relay with lever arm riding around armature yoke - uses lever arm to close magnetic circuit and increase contact spring-set travel
Inventor: KEZNICKL EDUARD ING
IPC: H01H50/64
Filed: 1980-10-07
Abstract: Lever arm electromagnetic relay provides increased travel of the switch block operating end of the switch-bar. The coil (1) is located on a yoke (2) which has straight end sections (9,10) and a curved front (11,12) which acts as a fulcrum for the switch block (5,6,7) loaded (at 18) lever arm (13). The lever arm (13) pivots around the curved outer (12) of the front yoke piece (11) to make the magnetic circuit when the relay is energised (17 onto 8). The lever arm (13) travel (a) at this end is less than that (a') at the switch block operating end (18). Also the distances are adjusted as the lever arm (13) rolls around the yoke face (12). Such operation enables a greater spacing to be achieved between the contact (6,7) of the spring-set.
