Title: Separating out mixed thermoplastic polymers from waste - by passing mix through extruder with different temperature zones and outlets
Inventor: HAEBERLE WILHELM
IPC: B29C48/03
Filed: 1978-08-29
Abstract: Thermoplastics are sepd. out and recovered from waste by feeding the waste by an extruder or similar conveying method to a separator which is divided into zones at different temps., so that the polymer with appropriate property is sepd. out in each zone. Simple low-cost system with low energy consumption is provided. Specifically washed/dried waste is fed into the hopper of an extruder, the barrel of which is divided into zones at different temps. Suitable pigment is also fed into the same hopper. Each zone has its own degassing vent and outlet, producing the series of extrusions which are cooled and granulated.

Title: Venetian blind swivelling slats - have light absorbing as well as light reflecting side
Inventor: HALOUSKA FRANZ
IPC: E06B9/36
Filed: 1978-10-05
Abstract: For controlling the amount of sunlight entering the interior, the venetian blind to be fitted behind windows has a series of slats set close together, adjustable about their longitudinal axis, forming a closed window cover when fully closed. These are light-reflecting on one side. The other flat side (26) of the slats (14) is light-absorbing. Both flat sides (26, 28) can be alternately set in position in front of the window pane. The slats pref. extend vertically, and are in the form of elongated hollow units, open at least at the top and bottom; or they may be solid. This enables the blind to contribute to temp. control as well as to darkening the interior.

Title: Circular knitter fabric thickness control - uses analogue circuits to give axial adjustment to needle cylinder
Inventor: BUCEK PAVEL DIPL ING
IPC: D04B9/02
Filed: 1979-03-07
Abstract: The system to control the thickness of the fabric produced by a circular knitter has an analogue control to adjust the axial positioning of the needle cylinder. This is formed by a proportional controller with >=2 inputs to provide data through an analogue position indicator for the needle cylinder and a digital/analogue converter. A digital control computer provides the input for the converter through a store. The proportional controller is connected through a store. The proportional controller is connected to the input of a power amplifier, with its output voltage linked through a kinematic chain to a servo-motor connected to the needle cylinder. The use of analogue switching circuits gives a simpler mechanism than a digital switching circuit system, so that a simple position indicator can be used, such as a potentiometer without requiring any additional logic circuits.

Title: Vehicle engine performance control - matches ignition timing fuel injection and fuel ratio to engine loading
Inventor: SCHROEER AXEL DR ING
IPC: F02D41/34
Filed: 1979-07-27
Abstract: The engine performance control controls the air/fuel ratio supplied to the engine cylinder dependent on the air intake pressure and interrupts the fuel mixture supply dependent on the engine loading. The fuel ratio is strengthened when the engine is again put under load, after idling, relative to the normal fuel ratio. Each engine cylinder has a fuel injection valve receiving a pulse for initiating the fuel injection supplied by a pulse generator responsive to the angular position of the crankshaft. The pulses are sequentially blocked in a pattern corresponding to the engine loading. A timing pulse generator provides pulses determining the opening duration of the injection valve and uses a counter controlled by an engine operating parameter and a multivibrator which can be switched between different time constants via a logic circuit.

Title: Copy lifting aid for photocopier - has double wire corona electrode to remove residual charge
Inventor: DENGLER LUDWIG
IPC: G03G15/00
Filed: 1979-07-28
Abstract: A copy lifting aid for a photocopier has a double wire corona electrode (35) behind the copy transfer electrode (21) to drag the copy off the process drum. The double electrode provide an attractive field over a set distance and replace mechanical, or air blast separators.

The double wire electrode has its wires at the same distance from the drum and mounted in a common housing. Both wires are at the same potential. A spacer (44) at the trailing edge of the electrode housing prevents the copy from touching the electrodes, while the separationcont rol prevents smearing of the toner copy prior to fixing.

Title: Control system for cooking meat - uses ultrasonic and radiation measuring systems to determine size and surface temp. to control heat
Inventor: HEYWANG HERMANN DIPL PHYS
IPC: G01K13/00
Filed: 1979-09-26
Abstract: The method of measuring the temperature of a piece of meat being roasted or grilled in an oven uses a contactless system. The temperature on the surface of the meat is measured by a suitable device, and the size of the piece of meat is measured by a second device. The measured values are entered into a calculator, and the output signals are used to control the roasting or cooking process. Where a flat piece of meat is being cooked, only its thickness is measured, using the distance between two carrier grids. The size can be measured by an ultrasonic echo system, and the surface temperature determined by infra red radiation.

Patent DE-3009504-A1 (DE)
Inventor: WEISS DIPL-MASCH-ING DR
IPC: H01H33/915
Filed: 1980-03-12
Abstract: An arc contact (19) which is arranged fixedly in a housing (11) can be engaged with, and disengaged from, a moving arc contact (31). One of these arc contacts is surrounded by a blasting nozzle (30) whose inlet (29) is connected to a pressure space containing an extinguishing gas. The outlet of the blasting nozzle is connected via a cooling device to an expansion space (112) which is provided in the housing. In order to ensure that the flow resistance opposing the extinguishing gas flowing out of the blasting nozzle is a minimum, with the cooling being equally efficient, and in order to prevent the cooled extinguishing gas striking the inside of the housing directly, the other arc contact (19) is surrounded by a blast tube (16) through which gas flowing out of the blasting nozzle can be blasted axially. At an axial distance from its end facing the blasting nozzle, the blast tube has radial passages (32), which are bounded by deflection rings (33) (which are shaped like guide vanes) and deflect at least a portion of the gas flowing out of the blasting nozzle (30) into an enveloping flow, which flows along the outside of the blast tube (16). The cooling device has cooling surfaces (36) which are essentially parallel to the switch axis (37) and are arranged in an enveloping space (35) between the outside of the blast tube (16) and a screening cylinder (34) which is coaxial thereto and extends at least as far as the passages (32). <IMAGE>

Inventor: PORTMANN HUBERT
IPC: G04G5/04
Filed: 1980-03-27
Abstract: A multistage counter 3, 5, 7, 10 normally counts seconds pulses from a frequency divider 2. Counters 5 and 7 are units and tens minutes counters and are set by shifting a counter 21 by button B to provide a "1" on output 21d. When a button A is then held down the seconds pulses pass through gates 17 and 22 and count the units counter 5 up to the numeral 0. A flip-flop 19, 26 is then set to disable gate 22 and enable gate 23 so that the units counter stays at the numeral 0 and the tens counter advances to the desired value, when button A is released, which resets the flip-flop. Button A is pressed again to count the units counter from the numeral 0 to the desired value. The invention in one embodiment simplifies the setting of a digital watch and reduces the time (number of pulses) needed to preset the units and tens of minutes counters. The invention can be extended to more than two counters and used for counters other than in clocks and watches.
