Title: Axial fan impeller, especially for a cooling fan for water-cooled internal combustion engines
Inventor: HAUSER KURT DIPL ING
IPC: B01D53/00
Filed: 1983-02-09
Abstract: An axial fan impeller is described, which is used in particular for a cooling fan for water-cooled internal combustion engines of commercial vehicles and comprises a hub and fan blades attached to this. In the area of the outlet edge of the fan blades a disc is attached to the hub, the diameter of which disc is at least 30% greater that the hub diameter. This disc may be of tapered design and be part of the circumferential surface of a cone, the tip of which lies in front of the hub rear edge in the direction of flow. A further conical front ring may also be assigned to this annular disc. This design leads to a reduction in the ventilation losses. The characteristic curve thereby becomes essentially more even than conventional designs. The efficiency may also be improved.

Title: Height-adjustable rest for jump poles
Inventor: TOENJES HERMANN
IPC: E06C9/04
Filed: 1983-02-26
Abstract: The invention relates to a height-adjustable rest on jump stands for equestrian sports, having a horizontally disposed rest part for jump poles, and a rest-fastening part which is held in rest-receiving elements, arranged vertically on the jump stands and facing the jump poles, so as to be adjustable in height in holding openings distributed over the length of the receiving elements at predetermined intervals. Up to now, rests could only be removed with some difficulty from a rest-receiving element in order to reconstruct jumps. The underlying object of the invention is to provide a rest of the type described at the beginning which can easily be removed from the rest-receiving element. According to the invention, provision is made for the receiving element to be a hollow profile which has openings between ladder-type webs, for the fastening part to have two holding claws which project from the rest, extend horizontally with mutual spacing, can be inserted in an assigned opening and whose free ends grip behind assigned webs, and for at least one of the holding claws to be guided displaceably in a sliding guide of the fastening part to reduce the spacing from the other holding claw in the fastening part.
Patent DE-3307480-A1 (DE)
Title: Frequency synthesiser
Inventor: HELPERT HARALD
IPC: H03L7/193
Filed: 1983-03-03
Abstract: The patent application relates to a frequency synthesiser which can generate a multiplicity of crystal-stabilised frequencies which are a predefined distance apart from one another (channel spacing), and which synthesiser can preferably be used as a transmitter oscillator or an oscillator for heterodyne frequencies in a radio receiver. Its main application concerns its use in portable radio sets, where minimum space requirement and minimum power consumption are crucial. The frequency synthesiser is characterised by the use of a commercially available integrated circuit which contains all the essential parts of a frequency synthesiser, such as     - a reference frequency oscillator   - a reference frequency divider   - a programmable divider   - a phase comparator, where the data to control the output frequency must be entered digitally as data words, each comprising 4 bits, and in each case 8 data words must be entered in series. This could hitherto be achieved only by assigning a microprocessor, including a data multiplexer and a data memory, to perform this task.   The present frequency synthesiser needs neither a microprocessor nor a data multiplexer, but merely two binary counters and a programmable semiconductor memory (EPROM). To save power, the data are retrieved from the semiconductor memory only when required. Original abstract incomplete.

Title: Arrangement for fastening a magnetic head support in a magnetic tape apparatus
Inventor: RUDI GUTTORM
IPC: G11B5/55
Filed: 1983-05-16
Abstract: The fastening of a magnetic head support (2) by means of which a magnetic head (1) can be positioned on various tracks of a magnetic tape (24) is performed by a spindle (3) bearing the magnetic head support (2) being arranged fixedly at its one end and protruding at its other end through a bore of a bearing plate (9) which is fastened adjustably on the magnetic tape apparatus. The bearing plate (9) preferably consists of resilient material and, after adjusting, is firmly connected at its one end to the magnetic tape apparatus. At its other end, the bearing plate (9) is releasably connected to the magnetic tape apparatus. For exchanging the magnetic head support (2), only this connection is released and the spindle (3) of the magnetic head support (2) can be removed from the bore once the bearing plate (9) has been bent away. After fitting a new magnetic head support (2), all that is necessary is to reestablish the releasable connection (10), without it being necessary to readjust the bearing plate (9). <IMAGE>

Title: Pressing machine with a stationary pressing body
Inventor: OBERT PETER PROF DIPL ING
IPC: D06F67/08
Filed: 1983-06-11
Abstract: Commercially run pressing machines are conventionally heated by means of highly pressurised steam with the aid of a steam generator available in the factories. To achieve the necessary pressing temperature, a relatively high pressure is required. In the design of the pressing body, the safety provisions for pressure vessels are to be adhered to and a pressure test is to be carried out. If the operator provides for the use of another energy medium, a correspondingly designed pressing body is necessary for this. The pressing machine according to the invention is heated by a steam generator which is part of the machine and which can be operated with oil, gas, electrical energy or process steam. The steam generator is connected to the machine by way of a steam feedline and a condensate return line. The pressing machine can be produced without consideration being given to the various energy media. A working medium boiling at low pressure is used as working material, so that the pressing body is not exposed to any appreciable internal pressure (Fig. 1). <IMAGE>

Title: Electronic camouflage installation for pulse transmitter - has deception sender with several aerials at preset distance from protected pulse transmitter
Inventor: MOERTL GUENTHER DIPL ING
IPC: G01S7/38
Filed: 1983-11-12
Abstract: The installation searches by a passive sensor a space angle region for electromagnetic pulse signals by means of a flank scanning circuit, which contains a time gate for time signal discrimination determining a preset width. From the results, signals for target search deflection are derived by a signal processor coupled behind the sensor. The derivation uses a misleading transmitter, transmitting identical pulse transmit pulses into the space endangered by enemy aircraft such that an associated misleading transmit signal appears at the passive sensor location at each point of the endagered space, at each time point and for each transmitted pulse within the time gate width. ADVANTAGE - Low-cost mobile, rapid installation.

Title: Anatomically deformed auricle supports for an eyeglass frame (spectacles)
Inventor: MATULLA KONRAD ED
IPC: G02C11/06
Filed: 1984-01-11
Abstract: Anatomically deformed auricle supports for an eyeglass frame relate to the exact matching of material, as any other type of prosthesis is matched to bodily parts. This results in the achievement of the absolute matching seat of the spectacles, the usual painful pressure points being eliminated, the more so on the cartilaginous rear of the auricle. It therefore becomes imperative, on the other hand, for the spectacle seat also to acquire or maintain the matching seat in the same way on the root of the nose, thus preventing the usual process of sliding down, as a result of which safeguarding the visual faculty and its defects endure, in the first case, and do not even become possible in the second case, so that this type of spectacle prosthesis admits of no other alternatives.
