Title: Process and circuit arrangement for retrieving binary signals recorded on a magnetic information carrier
Inventor: BAUER NORBERT DIPL ING
IPC: G11B20/10
Filed: 1981-12-19
Abstract: In the case of a process for retrieving binary signals recorded on a magnetic information carrier by way of determining the zero crossing of the magnetisation between successive track elements of the information carrier, the read signal E(t) of the information carrier is used to derive signals E(t- tau ) and E(t- tau /2), delayed by a time period  tau  and  tau /2 respectively. By multiplication of E(t) by E(t- tau ), the product P(t) = E(t) . E(t- tau ) is formed. E(t- tau /2) is compared with the value zero and, for the purpose of determining the zero crossing, the result of this comparison is only brought into effect if P(t) reaches a predetermined threshold value S1.

Title: Cooking valve
Inventor: HORN WALTER DIPL ING
IPC: A47J27/09
Filed: 1982-01-14
Abstract: The invention relates to a cooking valve for a pressure cooker, having a valve cap and an indicating pin guided therein which is displaced by the internal pressure in the pot and in dependence on said internal pressure from its position of rest counter to the force of an indicating spring, the position of the indicating pin serving as a pressure indication in that the indicating pin has at least two bearing orientation marks in the portion emerging from the valve cap on build up of pressure. In order to make the individual phases of the cooking process more clearly recognisable in such a cooking valve, provision is made according to the invention for indicating regions of visibly different surface structure to be provided on the outer surface of the indicating pin, said indicating regions being directly adjacent to one another or separated from one another only by a separating line or joint of comparatively small width. <IMAGE>
Patent DE-3201588-A1 (DE)
Title: Safety device for containers and conveying systems
Inventor: ISLIKER ALWIN
IPC: B65G53/66
Filed: 1982-01-20
Abstract: The safety device for containers and conveying systems is primarily connected to a connection piece on a tank car and preferably also to a connection line on the silo to be filled and is influenced via a pressure sensor arranged on the silo not only when there is a critical overpressure, but also when the conveying pressure is too small, so that the conveyance of the dusty or granular medium from the tank car is interrupted by a pressure sensor-controlled blocking by the safety device if the conveying pressure exceeds a predetermined critical pressure or if, for example due to the conveying line bursting, the medium being conveyed does not reach the silo, in which event a defined conveying pressure in the silo is certainly not achieved.
Patent DE-3204236-A1 (DE)
Title: Steam power plant with superheater and feedback of the exhaust steam including the heat of compression into the steam cycle
IPC: F01K21/00
Filed: 1982-02-08
Abstract: A steam cycle is proposed which is operated between the unsaturated, superheated state and the saturated to dry saturated state of a hot or cold steam, and thus avoids the continuous heating and evaporation of the feed liquid via the boiler or evaporator. It is therefore possible to carry out the compression and thus the feedback of the working substance by means of a turbocompressor, spiral compressor or positive displacement compressor virtually without any problem. In consequence, it is theoretically possible to use 100% of the primary heat transmitted to the cycle as mechanical work, without contradicting the entropy theorem in so doing. In the case of use of cold steams (chlorofluorohydrocarbons) as working substances, it is also possible to use low-temperature heat sources (e.g. water heat, air heat or geothermal heat; with or without temperature differences with respect to the environment) and thus to develop a new regenerative energy source with a relatively high energy density (approx. 20-40% of today's thermal power stations). Given multiple intermediate superheating, it is possible to achieve a high useful work ratio (expansion work/compression work) both with high-temperature and with low-temperature heat sources.
Patent DE-3211160-A1 (DE)
Title: Yarn disc brake
Inventor: KUEPPER WILHELM
IPC: B65H59/22
Filed: 1982-03-26
Abstract: The yarn disc brake (1) has a pneumatic loading device (8) which can be subjected to a pressure differing from atmospheric pressure and is centrally adjustable for a plurality of yarn disc brakes. In order, when many yarn disc brakes operate in parallel, for example in a creel, to obtain a desired uniform yarn braking of all the yarns of the yarn set, and in order to ensure that, even in the event of a central change of the loading pressure of the pneumatic loading device, no unforeseeable variations and irregularities of the braking effect of the individual yarn disc brakes occur, the individual yarn disc brake (1) acquires an adjustable mechanical loading device (20) interacting with a pneumatic loading device (8). <IMAGE>
Patent DE-3211657-A1 (DE)
Title: Safety valve with a lifting device
Inventor: SCHWARTZ WILLI
IPC: F16K17/168
Filed: 1982-03-30
Abstract: Safety valves are adjusted for a final pressure. If this final pressure is exceeded, they blow off. They have a lifting device for functional checking. Using this device, the valve can be opened directly and the medium hence released to blow off. The lifting device according to the invention limits the lifting movement for the closing devices and hence, during lifting, the corresponding blowing-off pressure and the quantity of gas lost. The valve spindle for raising the valve closing devices is bounded in its movement via a screwed-on threaded bush by an upper and a lower flange. It is a simple structure with no increase in the space requirement.

Title: Plastic tube placement rod
Inventor: KAUTZ GUENTER DR MED
IPC: A61B90/00
Filed: 1982-05-06
Abstract: For implantation of a tube in order to facilitate natural ingestion of food in patients with stenosing inoperable tumours of the upper digestive tract, the centrally perforated plastic tube placement rod is divided into three parts: 1. the placement tip which is 90 mm long and increases in diameter from 4 to 8 mm over a distance of 30 mm (Fig. 1a, b, c) which prevents abrupt dilation of the tumour-induced stenosis to the outer diameter of the tube to be implanted, provides reliable guidance through the tumour-induced stenosis and hence reduces the risk of perforation; 2. the tube guiding shaft which is about 160 mm long (Fig. 1 d) and has an outer diameter of 11 mm; and 3. the placement rod pushing shaft (Fig. 1 e) which is 650 mm long and has an outer diameter of 18 mm. The centrally perforated plastic tube placement rod, onto the tube guide shaft of which the tube is pushed, can be securely advanced through the tumour-induced stenosis over a steel guiding wire which has previously been introduced with an endoscope through the tumour-induced stenosis and bring the tube into the desired position. For implantation of a tube in patients with tumour-induced stenosis in the distal stomach, a second exemplary embodiment which is 100 cm long (Fig. 2a, b, c, d, e) was designed, whose tube guide shaft is 220 mm long and which additionally has, while retaining the other structural features, a plastic retaining ring for adaptation of the holding point to the particular tube length required (Fig. 2f). <IMAGE>
Patent DE-3220080-A1 (DE)
Title: Device for the contactless measurement of surface roughness
Inventor: LEONHARDT KLAUS DR ING
IPC: G01B11/30
Filed: 1982-05-28
Abstract: The invention relates to a device for the contactless measurement of surface roughness, which further develops and improves a device disclosed in German Offenlegungsschrift 3,020,044. In addition to the vertical surface roughness parameters, the correlation length representing a horizontal surface roughness parameter is determined. This is made possible due to the fact that the mirror (9) in Fig. 1 is divided and has different reflection factors, and that the detector (15) is constructed as a pair (15a, 15b) of detectors. It is preferable for one mirror half to be reflective, while the other mirror half is non-reflective. In this case, it can be advantageous for the reflective mirror half to be made from the same material as the surface to be tested. The effects of the steady radiation superimposed by the mirrors (9a, 9b) can also be generated by superimposition of corresponding direct currents relative to the detector currents, or by adding corresponding computed values in the evaluation computer. <IMAGE>

Patent DE-3244360-A1 (DE)
Title: Conveyor apparatus for supplying a dryer
Inventor: NEUMANN RAINER
IPC: B65G33/18
Filed: 1982-12-01
Abstract: The invention relates to a conveyor apparatus for supplying a dryer, in particular a rotary kiln for drying moist titanium dioxide. Hitherto, rotary kilns could not be charged with pre-dried titanium dioxide with a dry matter fraction of about 60-70%, since the pre-dried mass compresses and cakes together during conveying and hence the conveyor devices clog. To be able to feed rotary kilns with pre-dried titanium dioxide, it is provided that two parallel screws are arranged in a feed pipe opening into a rotary kiln, with their screw flights mutually engaging. The mutually engaging screw flights automatically clean themselves, so that a mass which cakes together during conveying has no possibility of depositing itself on the screw flights and their interspaces.

Title: Method and device for manufacturing ready-to-work mortar
Inventor: BADUM GEORG
IPC: B28C7/04
Filed: 1983-01-28
Abstract: In a method for manufacturing ready-to-work mortar by mixing sand, binder and possibly additives with water, it is envisaged, to simplify the stocking of the individual components and to achieve a constant mixing ratio and thus a good mortar quality, that the components are held available on the building site in a closed, portable container (1) which is divided in the vertical direction, are removed simultaneously and dry as required from the container (1) on its lower side in the required mixing ratio and only then added to water and mixed. To implement this method, use is made of a device with a portable, silo-like container (1) with a division (5 or 29, 30) which is vertical in the operating state and produces at least two mutually separated part containers (6, 7, 8 or 23, 24), and a removal and dispensing device (4 or 28) arranged below outlet openings (10, 11, 12 or 26, 27) of the part containers (6, 7, 8 or 23, 24). <IMAGE>

Title: Special key case for flat patent keys of the magnet and spring version
Inventor: STAHL HEINRICH
IPC: A45C11/32
Filed: 1983-03-02
Abstract: The special key case made of plastic and/or metallic material achieves the object of keeping keys in a protected and ordered manner and of bringing them into the locking position and the safekeeping position without any sorting operation. This is achieved by means of magnetic or spring force with the aid of a separate unmistakeable surface-marked structurally different slide for each key. It has room for one, two or four keys; if there are three keys, one slide is detained. The case is mainly intended for car keys. The keys can be tilted by 90% in the locking position to prevent knee injuries. However, the construction does not exclude the possibility of even wider use. The case not only safeguards keys, but makes it considerably easier to find particular keys, even in the dark. The respective key can be brought into the locking position without visual contact (as early as in the trouser pocket). The device appeals to the sense of play.

Patent DE-3311414-A1 (DE)
Title: Process and apparatus for producing a fibre/binder board, and fibre/binder board
Inventor: KOBER HARALD ING GRAD
IPC: D21J1/00
Filed: 1983-03-29
Abstract: In fibre/binder boards produced on board machines (endless-wire machines and cylinder machines), the nonwoven plies frequently only inadequately adhere to one another. The cause is the difference in weight between light fibres and binder. The heavier binder is drawn off with the excess production water. The binder content in the boards is so low that the desired strength is not reached. According to the invention, the charge mixture is now separated at a screen drum before it is charged to the felt. A fibre layer revolves with the screen drum. It is fixed below the felt to the surface thereof, on the one hand by the pressure of the screen drum and on the other hand by a pressure which is below atmospheric pressure. A water/binder mixture flows through the screen drum and drops like rain upon the precompacted fibre layer. The latter acts as a filter and prevents entrainment of binder with production water. This gives a compact nonwoven ply of a fibre layer and a binder layer. On winding up on a winding drum, fibre layers are intimately joined to binder layers of different nonwoven plies. Ply separations and surface damage are avoided. <IMAGE>
