Patent DE-3504376-A1 (DE)
Title: Internal combustion engine for motor vehicles
Inventor: SCHWAIGER ODILO
IPC: F02B3/06
Filed: 1985-02-08
Abstract: Two positive aspects, or contributions, to the evolution of passenger vehicle engines with far-reaching consequences: a) changes, which permit the omission of costly, energy-consuming cooling devices, b) with simultaneous gain by converting this amount of energy into work; they lie in the fact that the combustion chambers (piston at the top dead centre), which have the smallest possible surface areas, due to cylinder-head and piston-side (spherical) cup-shaped/boundaries, which on the piston side can be flatter or deeper in acordance with the process-dependent >> epsilon , are lined very effectively with thermal insulation, including a certain height of the cylinder wall, either by suitable ceramics (layered, porous), or by shell-like adapted vacuum chambers of thin-walled, corrosion-resistant sheet steel in various embodiments, with intermediate walls which, reflectively treated, are capable of reflecting the radiant heat (thermos flask effect), so that due to the keeping together of virtually the entire combustion heat, compared to an approximately 25% heat dissipation into the cooling water of conventional engines, for the same power the effective expansion potential (output) is produced by the combustion of a correspondingly smaller amount of fuel. The secondary consequence is the completely new design of cylinder head, pistons and cylinders, the latter of which may have (vertical) cooling fins on the stressed piston paths, ...

Patent DE-3532839-A1 (DE)
Inventor: BECKER GERT DIPL ING
IPC: B65B61/20
Filed: 1985-09-14
Abstract: When drinking straws are fastened to packs, it is particularly difficult to press the drinking straws precisely onto glue spots previously applied to the packs. For this purpose, it is proposed to determine the position of the packs on their conveyor and then actuate the glue applicator device or a press-on means for drinking straws when this point of the conveyor has been reached and consequently the pack has arrived in front of the glue applicator device or the straw press-on means. Alternatively, the control is determined by measuring the position and speed of the particular pack to be processed.

Title: Steering axle for tractors usable for agriculture, in particular for narrow-track tractors
Inventor: HONZEK ROBERT
IPC: B62D7/00
Filed: 1985-12-17
Abstract: A description is given of a steering axle for tractors usable for agriculture, in particular for narrow-track tractors, which steering axle comprises an axle support 1 bearing the wheels and an axle-core housing 2 arranged at least approximately centrally with respect to the axle support 1. In particular in the case of narrow-track tractors, the axle-core housing 2 forms an obstacle limiting the maximum steering angle  alpha  of the wheels 5 because of the small length of the axle support 1. In order to increase the maximum steering angle  alpha  the axle-core housing 2 has two lateral constrictions 17 in the region where the tyres 5a of the wheels 5 directly approach the axle-core housing 2, transversely to the longitudinal direction of the housing and corresponding to the desired maximum steering angle  alpha , the constrictions 17 being matched at least approximately in their position, size and shape to the outer contour of the tyres 5a.

Title: Luminaire
Inventor: EGLINSKI RAINER DIPL ING
IPC: F21V7/16
Filed: 1986-04-11
Abstract: In order to improve the emission characteristics of a luminaire having a line-shaped lamp, in particular a fluorescent lamp (18), use is made of a reflector (13) which is clamped in the housing between two grooves (16, 17). The distance of the grooves from one another is less than the distance of the terminal edges of the reflector in the relieved state. The reflector is constructed in this case as a specular, resilient and elastically bendable plate. In addition, the diffuser (enclosing bowl) is provided on its inside with a profile (20 to 26) which improves the transmission factor and whose profile shape depends on the light emitted by the lamp (18) and the reflector (13). <IMAGE>

Patent DE-3624462-A1 (DE)
Inventor: DOERR KARL HEINZ
IPC: C01B17/74
Filed: 1986-07-19
Abstract: Flue gases or other contaminated humid exhaust gases which contain SO3 are cooled by an indirect heat exchange in a heat exchanger to a temperature below the dew point temperature of sulfuric acid and are cooled further to a predetermined temperature in an SO3 condenser by means of dilute sulfuric acid, which is sprayed to flow in a countercurrent to the gas, whereby dilute sulfuric acid having a predetermined concentration is condensed. The gas leaving the SO3 condenser is scrubbed and cooled to a temperature from 40 DEG  to 55 DEG  C. in a fine scrubber by a treatment with a sprayed aqueous liquor. The exit gas is reheated to a predetermined temperature in a reheater by a treatment with sprayed dilute sulfuric acid from the SO3 and after the condensation of SO3 is passed through a filter. Dilute sulfuric acid from the reheater is sprayed into the SO3 condenser. The temperature of the gas in the reheater is so selected that the water which has been absorbed is not condensed but remains in the gaseous effluent. The exit temperature of the gas leaving the heat exchanger is approximately so selected that the temperature at which dilute sulfuric acid becomes available is approximately the same as the temperature of the gas in the reheater. The rate at which dilute sulfuric acid is sprayed is so adjusted that the dilute sulfuric acid withdrawn from the fine scrubber is at a temperature which is approximately the same as the required exit temperature of the gas leaving the SO3 condenser.

Patent DE-3642359-A1 (DE)
Title: Internal combustion engine
Inventor: RUETHER RAINER
IPC: F02B75/12
Filed: 1986-12-11
Abstract: A drum, which accommodates sixteen movable blades in guides running past the centre of rotation, rotates centrally in an oval capsule housing. Due to centrifugal force and the build-up of pressure inside the drum, the blades press against the inner wall of the capsule (blades pushing in increase the drum internal pressure, the expulsion tendency of the others is reinforced) and form sixteen chambers. The circulating air is compressed by lateral turbine wheels, passes by way of annular housing bays and inlet ports into the capsule housing and is further compressed during one quarter revolution. Following direct fuel injection a glow plug ignites the mixture; the expanding gases drive the shaft rigidly connected to the drum by way of the blades pushing outwards. The exhaust gases expelled during a further quarter revolution transmit their flow energy to the compressor turbine wheels by way of plates arranged on the inside and wash around the compression and combustion area to increase the operating temperature. The advantages of this compact engine are high power yield, vibration-free running characteristics, utilisation of exhaust gas flow/heat energy, turbine-like continuous mixture ignition, few moving parts due to the absence of inlet/exhaust valves, camshaft, combustion with low pollutant emissions.

Filed: 1986-12-22
Abstract: The invention relates to a device for raising an alternating stripper roller in printing machines, which device can be placed against the forme inking roller and/or the forme damping roller or against the varnishing roller. The object of the invention is to provide a device, which is linked to the machine control and can be switched selectively, for raising the stripper roller arranged between the inking and damping units, it also being possible for the damping unit to be used as a varnishing unit and, in the case of a stoppage, the stripper roller always being raised from the varnishing roller and being raised from the forme damping roller in the case of inks which are sensitive to damping medium. According to the invention, this is achieved in that a bar extending in the transverse direction is mounted on the lever which is pivotable about the centre-point of the ink distributing cylinder, and a bearing block receiving a double lever is attached to the side wall, one end of said bearing block being connected in an articulated manner via a coupler to an operating cylinder controlled by the machine and a ball bearing interacting with the bar being attached at the other end of said bearing block. The operating cylinder used is a pneumatic or hydraulic operating cylinder.
