Patent DE-2838279-A1 (DE)
Title: Integrator system for communications circuits - uses charge coupled devices connected between de-multiplexer and multiplexer
Inventor: BOSOTTI LUCIANO
IPC: G06G7/184
Filed: 1978-09-01
Abstract: The integrator comprises a generator (GC) which delivers a continuous input current to a charge coupled device (CTD). The latter is in the form of a delay line with three electrodes (E1, 2, 3) driven from a clock generator (CK). An output stage (CU) detects the output voltage of the stored charge packets. The input stage (EO) acts as a gate which can have a high impedance condition or a low impedance condition which it adopts during the period of the integration interval ( ). The starting point is controlled by the clock. This also controls the electrodes so that the charge in the form of packets of minority carriers is successively stored and passed to the output. The output signal is proportional to the integral of the input. A number of identical integrators may be connected between a demultiplexer and a multiplexer.

Title: Injection moulding apparatus - in which a mould is moved from an injection station to a cooling and pressure applying station
Inventor: CHANG LONG FEI
IPC: B29C45/06
Filed: 1978-12-21
Abstract: Injection moulding appts. includes a mould carried by a turntable and indexable from an injection station to a station at which the injected material is cooled under pressure. The mould includes a wide sprue opening and injection is effected under relatively low pressure (5000 p.s.i). Pressure is applied during cooling by a hydraulically driven rod which is inserted into the sprue opening. By varying the pressure and temp. during cooling, close control over the degradation of the material can be achieved. A quoted working material is polyethylene terephthalate. High pressure injection gear is avoided and flashing during injection is reduced. Close control can be achieved over the physical properties of the injected article. The arrangement is of particular use in making parison to be later blown to shape.

Title: Separating system for conveyed workpieces - detects movements of flap by two or more stacked workpieces and actuating separating deflector
Inventor: PIETZSCH LUDWIG DIPL ING DR
IPC: B65G47/14
Filed: 1979-02-19
Abstract: The handling system separates workpieces and prevents them from becoming stacked during conveyance. A moving flap (4) is positioned such that it normally allows only one workpiece (5) to pass between it and the conveyor. A detector (6, 7) responds to any movement of the flap caused by more than one workpiece passing it simultaneously (e.g. one workpiece on top of another). The detector actuates a device that separates the second workpiece from the first. The detector may be a proximity switch (inductive or capacitive) and excites a solenoid (3) when the flap is moved. The solenoid moves a deflector plate that separates the workpieces.

Title: Switch-off mechanism for coffee or tea makers - has simple bell and hammer triggered by snap catch when machine switched off
Inventor: WAHNSCHAFFE K-DIETER ING GRAD
IPC: A47J31/52
Filed: 1979-03-22
Abstract: The switch-off mechanism includes a lever which is biased by a jug or pot on one side and a spring on the other and interacts with a snap catch (14) which in turn engages on a hammer (19) to cause it to strike the bell member (20) as the coffe maker is switched off. Thus when the predetermined full level has been reached the snap catch snaps out and into a recess of the lever so that a switch is opened and the coffee maker switched off. The bell (20) and hammer (19) can be arranged so that the head (19') of the hammer strikes the bell along the side so that it does not touch the bell in the rest position.

Title: Lead recovery from crushed battery scrap - where mixt. of scrap and water is fed into cyclone to separate dense and lightweight materials
Inventor: DREISSEN HUBERT HERMAN
IPC: H01M10/54
Filed: 1979-04-11
Abstract: The scrap has size is not >50 mm., and is free from both acid and ferromagnetic materials. It is mixed with water and fed into at least one hydrocyclone which has a cone with a sharp cone of 30-120 degrees. The cyclone separates the mixt. into two fractions (I, II).

Both fractions fall onto dewatering sieves. Each fraction pref. falls onto a first, curved sieve, and then travels onto a second sieve. Water recovered from the four sieves is pref. recirculated for remixing with crushed scrap.

Patent DE-2925130-A1 (DE)
Title: Pressure monitoring system for e.g. vehicle tyre - uses measurement of ultrasonic energy reflected by tyre wall or road surface to indicate loss of air
Inventor: STOLZ ALBERT DIPL ING
IPC: B60C23/06
Filed: 1979-06-22
Abstract: The tyre-pressure monitoring system produces a signal when the side wall of a tyre deforms outwardly beyond a given maximum limit to indicate loss of air in the tyre. The system (6) has an ultrasonic transmitter directing ultrasound waves onto the side wall of the tyre. An ultrasound receiver receives waves reflected from the tyre wall. The receiver output is a function of the time required by the waves to travel from the transmitter to the receiver and is a measure of how far the tyre wall is away from the receiver, i.e. the deformation of the wall. The receiver output is converted into an electrical signal suitable for displaying on the driver's instrument panel. Instead of the wall of the tyre, the ultrasonic waves may be reflected from the surface of the road to achieve the same result. Each tyre may have its own display or may share a display.

Title: Alignment of x=ray multiple image exposure - using microprocessor which displays possible sub-divisions and incompatibilities
Inventor: GANS-GREHL GUENTER
IPC: G03B42/02
Filed: 1979-09-01
Abstract: The correct alignment of the film cassette in an X-ray system is for taking multi-images and is controlled by a micro-processor which takes into account the cassette size and decides what, if any, sub-dividion of the available film is possible. Two sliding bars (12) at right angles with magnets (11) at one end which face reed switches (10) report the cassette size to the processor. The size is shown on a display (4) and a 3 x 3 matrix display (9) indicates the possible sub divisions of the film which may then be selected by a push button (2). Another button (3) enables the operation of a collimator (7). The subsequently reduced area of exposed film is monitored and an error message in the form of a blinking display is given if the dimensions are incompatible.
