Patent DE-3149500-A1 (DE)
Title: Four-stroke combustion engine
Inventor: VOIGT DIETER DIPL ING
IPC: F02B75/02
Filed: 1981-12-14
Abstract: In order to obtain strong swirling of the fresh gas at the start of combustion on four-stroke combustion engines, a tangentially arranged inlet opening with a control slide valve arranged in front of it and controlled by the piston is provided only in the cylinder. During the intake stroke the piston releases the inlet opening only once a high vacuum is formed in the cylinder before reaching the bottom piston reversal point, so that, owing to the now open control slide valve, fresh gas flows at high speed into the cylinder and causes strong swirling about the cylinder axis. During the compression stroke the fresh gas is preferably driven into a rotationally symmetrical, radially constricted combustion chamber with further increase in the swirling. Following ignition and combustion of the charge the inlet opening, freed again by the piston, is now inoperative, since the control slide valve arranged in front is now closed. The exhaust process occurs by way of the exhaust valve located in the cylinder head. Combustion engines designed in this way permit a very high compression ratio on spark ignition engines and complete combustion with emission of exhaust gases containing few pollutants on direct injection diesel engines. <IMAGE>

Title: Hot-air airship
Inventor: VOLKRODT WOLFGANG DR ING
IPC: B64B1/58
Filed: 1982-01-09
Abstract: A hot-air airship, consisting of an inflatable balloon envelope (1), a supporting and clamping framework (4), lateral and vertical control surfaces (5, 6) and a drive used for forwards propulsion, characterised in that internal-combustion engines are used for the forwards propulsion whose entire exhaust heat is used for generating the balloon lift by means of hot air, and the balloon envelope has an aerodynamically advantageous, droplet-shaped form in the forwards direction. When using conventional internal-combustion engines, a fan (17) is seated rigidly on its shaft and a propeller (12) is seated so that it can be engaged. The fan air which flows past the internal-combustion engine (16) and is thus heated is used, after being mixed with the hot exhaust gases (20), as the hot air for inflating the balloon. <IMAGE>
Patent DE-3207698-A1 (DE)
Title: Industrial robot with a device for increasing working accuracy
Inventor: WIDL GERHARD DR ING
IPC: B25J9/16
Filed: 1982-03-04
Abstract: In an industrial robot, the speed, working accuracy or loadability can be increased without strengthening the stability via the construction, if provision is made for measuring devices which detect the positional deviation of the free robot-arm end and correct this by controlling the corresponding axles. Even vibrations of the robot-arm end can be damped by a corresponding control of these axles. As a result, a situation is avoided where the greater masses resulting from increasing the stability by constructional measures increase the centrifugal forces or Coriolis forces and therefore the speed or the working accuracy can be only slightly improved.

Patent DE-3210097-A1 (DE)
Title: Panel-type heating conductor for flexible heat appliances
IPC: H05B3/34
Filed: 1982-03-19
Abstract: For the purpose of the present invention, panel-type heating conductors are composed of a compact flexible woven fabric made of plastic threads (preferably polyester) whose entire surface is coated with a compact, continuous metal (preferably nickel) layer. Said layer can be produced either by chemical reduction or by electrodeposition. Since the thickness of said metallic coating can be varied within certain limits employing both methods of production, resistance values can be produced, also within certain limits, which are matched to the electrical power consumption of the heating conductor for a given operating voltage. Good reproducibility of the desired resistance value can be achieved by appropriate measurement-controlled implementation of the coating method. The polyester woven fabric preferably used as carrier is composed of prestretched threads and is extremely resistant to mechanical loads, which result in only slight permanent deformation or none at all. Contact is made to such panel-type heating conductors preferably by means of metal gauze strips sewn in on two opposite sides.
Patent DE-3211182-A1 (DE)
Title: Method for controlling the torque of an asynchronous machine
Inventor: KAMPSCHULTE BURKHARD DR ING
IPC: H02P27/04
Filed: 1982-03-26
Abstract: In this method for controlling the torque of an asynchronous machine (1) which can be supplied via an invertor (2) or converter from a DC source (3) or AC source, the stator frequency (f1) is formed by addition of a fed-back rotation frequency actual value (fn) and a slip-frequency preset valve (f2v) corresponding to a predetermined torque (M). The feedback of the rotation frequency actual value (fn) is in this case delayed. In consequence, during rapid changes in the rotation frequency actual value (fn), the torque actual value (Mact) on the asynchronous machine (1) is reduced, which has a speed-stabilising effect. The method is used especially for controlling the drives of rail vehicles. <IMAGE>

Title: Roller apron for a continuous casting installation and a method for the dimensionally accurate installation of rollers in the roller apron
IPC: B22D11/128
Filed: 1982-04-01
Abstract: In a roller apron for a continuous casting installation with a roller apron track having rollers, each roller has a number of annular recesses to form cylindrical bearing journals which are mounted in bearings supported on a supporting construction, namely in a fixed-location bearing and at least one floating bearing. In order to avoid exposing the bearings of the rollers in the roller apron to excessive axial forces caused by axial displacement of the bearing or of the roller while ensuring that the roller apron is of as simple construction as possible, one or more of the floating bearings is designed as a cylindrical roller bearing with an inner race and an outer race inserted into a housing, the outer race being provided with a convex outer surface which is slidable relative to an inner surface of the housing to allow angled positions. <IMAGE>

Title: Process for hydrocracking heavy oil
Inventor: BELINKO KEITH
IPC: C10G47/06
Filed: 1982-06-09
Abstract: An improved process for hydrocracking heavy oil, such as oils extracted from oil sand, is described. In this case, the oil charge is passed in the presence of excess hydrogen through a tubular hydrocracking zone, and the liquid reaction product from the upper end of the zone is separated into a gas stream of material boiling within a wide range and into a liquid phase containing high-boiling hydrocarbons. The charge according to the invention consists of a suspension of heavy oil of hydrocarbons and finely dispersed pyrite. The presence of the pyrite in the charge has the effect of greatly reducing the formation of coke precursors and hence the formation of carbonaceous deposits in the reaction zone.

Title: Process for the production of products resembling printed matter, especially visiting cards, publicity cards and business cards
Inventor: KOLTAI STEPHAN
IPC: G03B15/00
Filed: 1982-10-07
Abstract: The production of visiting cards, business cards, publicity cards or the like, which contain by way of total image an image portion (1) and a text portion (2) is made simpler and cheaper in that a printable original e.g. a negative, is separately made both of the image portion (1) and also of the text portion (2). The originals are brought into the correct mutual register, which corresponds to the desired total image. The total original thus obtained is exposed onto a light-sensitive layer. By photochemical development of the exposed light-sensitive layer, the end product is then obtained. The latter is thus a copy obtained by photographic means. Since no printing process of the conventional type takes place, this end product may be produced more cheaply, more rapidly and with truer colours than the conventional printed products. <IMAGE>
