Patent DE-3120641-A1 (DE)
Title: Indirect extrusion press
Inventor: ASARI AKIRA
IPC: B21C35/04
Filed: 1981-05-23
Abstract: A description is given of an indirect extrusion press with a press frame having a "frame" structure. The press frame consists of a press plate and a frame plate for the main cylinder, which are rigidly connected. A receiver for blanks is arranged movably between the press plate and the frame plate. A fixed die ram extends from the press plate towards the blank receiver, while an extrusion ram projects from the frame plate towards the blank receiver. Hydraulic cylinders are provided on the press plate for the purpose of moving the receiver backwards and forwards along the central longitudinal axis of the extrusion press. Hydraulic coupling cylinders are furthermore provided on the cross head from which the extrusion ram projects. The relative position of the receiver and of the extrusion ram is held constant during a stroke of the extrusion press, so that the force exerted for the displacement of the receiver is added to the extrusion force. An effective release of the receiver from the blank on completion of the extrusion process can be achieved by using not only the cylinders provided for the displacement of the receiver but also by the use of the coupling cylinders. An intermediate frame displaceable on the die ram can also be provided. The force for the displacement of the intermediate frame can likewise be added to the extrusion force or to the force required for the release process. The additional extrusion force is taken up by the receiver and the moving parts associated with it, thereby eliminating the need to reinforce the press frame. As a result, it is possible to reduce the number of components and the weight of the extrusion press, the construction of which can thus be simplified.

Title: Paper strip feeder of a line printer
Inventor: KUGYELA ATTILA
IPC: G07G1/06
Filed: 1981-09-04
Abstract: A paper strip feeder of a line printer, in particular in electronic till machines, in which a toothed segment wheel having two toothed segments is provided for selectively carrying out a double-line feed of the paper strip running around the feed roller and the single-line feed thereof, the one toothed segment interacting directly with the driving gear of the feed roller, and the other toothed segment interacting with a reversing wheel which meshes with the driving gear and is held selectively in the rotary path of the toothed segment assigned to it or can be moved away out of the rotary path thereof. In the former case, during each circulation of the toothed segment wheel, the paper strip is moved back by one line spacing, being driven by the toothed segment and the reversing wheel, then being moved forwards again by two line spacings, driven by the toothed segment, so that, as a result, it is advanced by one line spacing. In the latter case, in contrast, the toothed segment interacting with the reversing wheel passes freely by the latter so that the return movement of the paper strip by one line spacing is omitted and only its advancing movement by two line spacings takes place.
Patent DE-3135181-A1 (DE)
Title: Liquid lens
Inventor: PLADDIES RUDOLF
IPC: G02B3/12
Filed: 1981-09-05
Abstract: The liquid lens, consisting of two plastic shells, a retaining ring or retaining tube with filling stubs, and a liquid is intended to have possibilities of use chiefly in research and teaching. It can be produced easily and quickly to any size, shape or thickness. The aim is for it to permit the detection of unknown or known (eg. neutrino) rays by means of metallic liquids (eg. boron, borax or perborates). With other fillings, its use as a "gravitation antenna" for waves (eg. gravity waves) is conceivable. It can probably be used, filled with air or other gases, as a large optical lens in space. When making use, filled with water, of solar energy, it would render tracking of the sun superfluous when used in large numbers arranged in the shape of a semicircle. Its use in glass fibre optics can play a new role: appropriately enlarged and by contrast with the procedure in the known glass fibre luminaire, which guides the light to the end points of hundreds of glass fibres, it becomes highly centralised. Further possibilities of light concentration are offered by the arrangement of lenses and "glass cables", as well as their incorporation into laser technology. <IMAGE>

Title: Device for detecting the formation of ice and/or hoar frost
Inventor: POPP HANNS-PETER PROF DR
IPC: G01W1/00
Filed: 1982-02-12
Abstract: Since the devices used hitherto, operating with temperature sensors, for detecting the formation of ice and/or hoar frost occasionally signal the formation of ice or hoar frost at negative temperatures although the former are not yet actually present, or indicate no icing although it has already occurred at positive temperatures, the invention provides a device which despite a relatively simple design always reliably detects and quantitatively measures formation of ice or hoar frost. The device consists of a light source (3) which directs a beam of polarised light onto the surface (1) of a body (2) coated with a layer (S) of ice or hoar frost. The reflected light passes to a light-receiving device (13), and if the polarised light is depolarised by the layer (S) of ice or hoar frost it passes through a single-tuned filter (23) onto a photodiode (24), so that, for example, a threshold-value detector (26) emits a signal characteristic of the formation of ice or hoar frost. <IMAGE>

Title: Method for suppressing interfering radiators for a missile guidance method
Inventor: SCHMIDT HELMUT
IPC: G01S3/786
Filed: 1982-03-27
Abstract: In order to suppress interfering radiators for an optical missile guidance method which is carried out using a VDU and a monitor, an electronic gate downstream of the VDU is used to pass only image pulses having a prescribed pulse width which decreases as a function of the distance of the missile from the VDU. For this purpose, either the start and/or the duration of the pass phase of the electronic gate can be controlled periodically with the image frequency of the VDU by means of a programmer, or only the start of the pass phase of the electronic gate is prescribed periodically with the image frequency of the VDU by means of the instantaneous horizontal and/or vertical deflecting voltages associated with the image pulse of the missile radiator. It is ensured in this way that only the radiator at the rear of the missile is located and only the corresponding deviation values of this radiator from the line of sight are used to form guidance signals. <IMAGE>

Title: Starting aid and mixture preparation support principally for cold starting of spark-ignition engines
Inventor: REITZ JOHANNES
IPC: F02M27/08
Filed: 1982-09-15
Abstract: The state of the art is the starting aid for supporting the mixture preparation principally when cold starting spark-ignition engines by electrical resistance heating. This is necessary by reason of the exhaust emissions legislation. Processes exist which owing to an enlarged surface are more efficient in getting fuel particles to evaporate, principally in the starting phase (MTZ December 1982 Report: The new 55kW engine as largest engine size for the VW Polo Coupe p.561 et seq). The energy requirement is very high, up to approx. 700 watts depending on the temperature. The starting aid and support for mixture preparation according to the invention, principally for cold starting of spark-ignition engines, utilises ultrasonic atomisation and requires less than 1/10th to 1/100th of the energy of resistance heating. No heating-up time is required and considerably more energy is available for the starter than hitherto.
