Patent DE-3101094-A1 (DE)
Title: Lining of a grinding or polishing drum and processes for producing and using a lining of this type
Inventor: BALZ GUNTHER W
IPC: B24B31/02
Filed: 1981-01-15
Abstract: A grinding-drum or polishing-drum lining, particularly suitable for use in grinding machines used in industry or trade, has a compressible elastomeric substrate in which particulate, insoluble abrasion material is uniformly distributed. This lining has an outer or working surface, that is to say a gripping surface through which abrasion-medium particles are dispersed and which can regenerate of its own accord as a consequence of wear which occurs during use. The abrasion-medium particles uniformly distributed in the lining material have an average particle size of between 1 and 100  mu m and have a hardness of at least 1 on the Mohs' hardness scale. Furthermore, this abrasion material is insoluble in the elastomeric substrate and in the starting materials, reaction partners and/or solvents used for its production. This special grinding-drum or polishing-drum lining increases the working action within the drum and decreases the number of inactive, collapsed or "dead" locations within the drum when a mass of loose polishing elements and the workpieces to be treated is circulated therein. The invention further discloses grinding or polishing drums provided with this lining, grinding machines equipped with drums of this type and processes for producing and using said lining.

Patent DE-3113012-A1 (DE)
Title: Covering device for covering the nozzles and the nozzle surface on an ink jet print head
Inventor: SCHULZ HARTMUT ING GRAD
IPC: B41J2/165
Filed: 1981-04-01
Abstract: The covering device serves for the secure closure of the nozzles and nozzle surface in non-printing times, during storage and transportation. On the one hand, the ink jet print head (14) moved into the edge position comes with its nozzle surface (31) into contact with the surface (20) of the covering pad (21) mounted in the covering device and, on the other hand, a tensioning region (34) on the covering device engages on the rear side (38) facing away from the nozzle surface. The tensioning region (34), the centre of the nozzles emerging from the nozzle surface (31) and the centre-point (17) of the rotary core for the covering pad (21) form a straight line (36) in the drawing. The ink jet print head (14) can be moved by a small amount beyond said region so that the tensioning forces built up as a result of the ink jet print head being moved into the covering position are slightly decreased along the straight line (36) when the ink jet print head has passed over the latter, thus resulting in a self-retaining effect. <IMAGE>

Patent DE-3131832-A1 (DE)
Title: Electrical switch
Inventor: MUTSCHLER ERICH
IPC: H01H13/02
Filed: 1981-08-12
Abstract: In the case of a known electrical switch having a housing, having two operating devices to which in each case one switching element is allocated, via which a contact link can be moved, having function illumination which includes a light element from which light passes to the outside when one or other of the operating devices has been correspondingly operated, and having a plurality of stationary contacts of which in each case two are connected to one another by the two contact links in the functional position, the incandescent lamp which is used as the light element is permanently switched on. Its light is passed through to an indicating window or is covered depending on the position of the shutter which can be displaced via the two operating devices. In order to avoid moving parts for controlling the light from the light element, a power supply contact plate for the light element is, according to the invention, fixed in the housing of the switch and can be acted on by the contact links in the functional position. In the case of such a structure, the light element in each case illuminates only when at least one contact link assumes its functional position. The power supply contact plate, which is separated from the stationary contacts, ensures that, when only one contact link is switched on, no current flows via the power supply contact plate, and possibly via further parts of the illumination device, to the second, switched-off contact link.

Title: Method of analysing gas/air mixtures and device for carrying out the same
Inventor: ZAZIGIN ALEKSANDR SERGEEVIC
IPC: G01M3/22
Filed: 1982-01-05
Abstract: The device for analysing gas/air mixtures which makes possible a method of analysing gas/air mixtures comprises a working chamber (2) which is connected to a gas/air mixture sampler (1) and a vacuum pump (7). An infrared radiation source (9) is sited relatively to the inlet opening (8) of the chamber (2) in such a way that a radiation switch (10) and a modulator (11) are situated one behind the other in the direction of radiation in the infrared radiation path between the radiation source (9) and the inlet opening (8). Mounted in the path of the radiation which has passed through the chamber (2) containing the gas/air mixture is an infrared radiation receiver (12) which is connected electrically to the inputs of a comparison circuit (16) which is connected to an indicating unit (17). Electric valves (5, 6) are mounted in the immediate vicinity of the input and of the output of the working chamber (2), and situated at the input of the chamber (2) there is also a pressure pump (4) which is used to feed the gas/air mixture with the valve (6) closed until the mixture pressure exceeds the atmospheric pressure, and this pressure is kept constant with valves (5, 6) closed at least for three cycles of the modulations occurring after the absorption bands of the test gas. The effect of the infrared radiation sets in from that moment on when the pressure of the gas/air mixture exceeds the atmospheric pressure. <IMAGE>

Title: Logical stereometric toy
Inventor: ROHRBACH KARL
IPC: A63F9/08
Filed: 1982-02-24
Abstract: A logical stereometric toy is assembled from a plurality of suspension elements (3) and play elements (10; 11; 12) to form a unit which has the basic shape of an octahedron (1). The suspension and play elements (3; 10; 11; 12) each belong to a set (5; 6; 7; 8) within which they are mutually identical. The play elements (10; 11; 12) are so designed that they are suspended with the suspension elements (3) on a central body (2) located in the geometrical centre of the octahedron. The octahedron (1) can be twisted in twelve layers (66; 67) on eight twisting surfaces (55) about four axes (49; 50; 51; 52), these axes forming a three-dimensional axis intersection. As a result of the sequence of different twists, the positions of the individual play elements (10; 11; 12) within all groups (6; 7; 8) can be exchanged, so that a very great number of variations exists. <IMAGE>

Patent DE-3211844-A1 (DE)
Title: Quick-acting clamping device for rotating, disc-shaped tools, such as cutting-off wheels, grinding wheels and circular saws
Inventor: NIGGEMANN JOHANNES
IPC: B24B45/00
Filed: 1982-03-31
Abstract: The invention relates to the field of power tools and stationary machine tools wherever rotating, high-speed tools are used, in particular portable grinding machines and portable circular saws. The clamping device is to clamp tools quickly and reliably, such as, for example, a cutting-off wheel, which has to be exchanged frequently. During this tool-clamping operation, which as far as possible is a simple operation for the machine operator, the use of further tools such as open-ended spanners or ring-nut keys is to be dispensed with. The idea behind the invention is to use the rotary energy in the machine tool to firmly and reliably clamp the tool for the duration of its use. The object is achieved in that a small portion of the rotating working energy is converted into centrifugal force and is transmitted by a linkage to a nut which acts in the direction of the clamping force. <IMAGE>
Patent DE-3212480-A1 (DE)
Title: Method and arrangement for recovering the clock signal in digital data transmission and digital data recording
Inventor: FIEDLER UDO DIPL ING
IPC: G11B20/14
Filed: 1982-04-03
Abstract: A problem in digital data transmission and digital data recording lies in the regeneration of the clock signal, with the correct frequency and phase, from the received or read data. In particular, the regenerated clock should enable temporal evaluation of the data string in the symbol mid-point (bit mid-point); misinterpretation of the data is then least likely in the case of jitter-affected data edges. The object is solved here with a phase-locked loop (PLL) which is characterised by the mode of operation of its phase detector; in each case the time interval ( DELTA T) between one data edge and the following reference edge (= evaluation time) of the regenerated clock is compared with a reference time interval ( tau R) and an output signal proportional to ( DELTA T &boxdr&  tau R) is formed. A circuit arrangement to implement this phase comparison is shown in Figure 6; evaluation times are ensured without adjustment in the symbol mid-point through the use of the half period duration of the regenerated clock signal as a reference time interval ( tau R). For the phase-locked loop, the sawtooth characteristic of the phase detector extending over 2 pi  is effective after each data edge only; when identical signals follow one another in the data signal, the phase detector disconnects the phase-locked loop until the next data edge arrives. <IMAGE>
Patent DE-3214448-A1 (DE)
Title: Two-wheeled trailer for bicycles and mopeds
Inventor: MALWITZ EBERHARD
IPC: B62K27/00
Filed: 1982-04-20
Abstract: The invention relates to a trailer and a handcart with a removable superstructure and shaft attached laterally to the frame in a vertically adjustable fashion. The known bicycle trailers are unsuitable for fast racing bikes. They are often too heavy, have inadequate suspension and bad driving properties. No trailer is known which is also suitable for example as a shopping trolley with a removable and lockable superstructure (shopping bag) and vertically adjustable shaft. Likewise, it is not possible in any known trailer to store the complete chassis with wheels in its superstructure (e.g. travel bag). The object of the invention is to provide a sporty, light-weight multi-purpose trailer or handcart which does not have the previously mentioned disadvantages. This object is achieved as follows: the design of the frame structure as a bending and torsioned spring, the coupling of the shaft in the vicinity of the rear wheel axle of the bicycle and the use of a light-weight construction ensure good driving properties. By means of collapsible frame halves and the rearwardly swivelable shaft, the complete chassis with wheels can be stored in the superstructure of the trailer whose height is smaller than the diameter of the wheel and whose width is smaller than the width of the frame. By means of the vertical adjustability of the shaft, the individual use for different bicycles and as a handcart is possible. The trailer superstructure which is constructed as a travel bag can be locked and unlocked simply and quickly by means of catch locks on the frame.

Title: Method of converting an offset litho into a positive gravure screen
Inventor: BIEHL KARL MARIA
IPC: G03F5/20
Filed: 1982-05-21
Abstract: The novel method of converting an offset litho into a positive gravure screen improves the so-called conversion method hitherto practised quite substantially since the positive gravure screen produced in accordance with the invention has the substantial advantage of producing a quality gravure which is superior in its brilliancy and simple technique to all previous gravure methods. The novel method produces a true positive gravure cell wall in the approximately 50-100% areas and round dots of different size in the approximately 50-5% areas which result in the brilliancy and the desired gradation of a true gravure.
