Patent DE-3100117-A1 (DE)
Title: Process and apparatus for obtaining shale oil
Inventor: CHIARAMONTE GERALD
IPC: C10G1/02
Filed: 1981-01-05
Abstract: In the pyrolysis of oil shale, porous, brittle waste shale is formed in kerogen-rich shale particles owing to the decomposition of the kerogen which is present as a binder in the crude oil shale. By pulverising the formerly kerogen-rich, porous waste shale in a fluidised bed which operates with a gas surface velocity of 2.1 to 42 m/s, the porous material is comminuted so that it can be discharged with the waste gas. The remaining larger particles are based on shale having a low kerogen content and therefore do not have the large surface area and corresponding strong absorptivity which could adversely affect the yield in the pyrolysis. These coarser particles can therefore be used as effective heat media and can be transported back into the pyrolysis zone. <IMAGE>
Patent DE-3102509-A1 (DE)
Title: Gear machine (pump or motor)
Inventor: DWORAK WILHELM
IPC: F04C2/08
Filed: 1981-01-27
Abstract: In the case of hydraulic gear machines according to Figure 1 it is essential that the leakage gaps be kept as small as possible. These can form not only between the lateral faces of the gear wheels and the adjacent casing walls, but in particular also on the front faces of the gear wheels. In order to reduce such leakage gaps, the gear wheels (14, 15), after the machine has been assembled, are allowed, by suitable measures, to bed in slightly into the casing recess (13) accommodating them. This bedding-in takes place in sealing zones (A, B) on the high-pressure side of the machine. The suitable measures consist either in displacing the central casing section (10) towards the gear wheels or, in the case that they are supported in radially movable bearing bodies (36), in displacing the latter towards the high-pressure side. Displacement of said parts is effected in an assembly state in which the screws holding together the casing sections are not yet fully tightened. Only after the gear wheels have run in into the sealing regions, are the screws fully tightened. <IMAGE>

Title: Device for restraining children on motor vehicle seats equipped with passive safety belts
Inventor: SCHWANT WILFRIED
IPC: B60R22/04
Filed: 1981-02-28
Abstract: A device for restraining children on motor vehicle seats equipped with passive safety belts which are automatically put on when the adjacent door is closed, especially with a passive inclined shoulder belt, has an interception body which is arranged in front of the body of the child, is held by at least one holding belt anchored to the vehicle, and takes the form of a small table made of a semi-elastic material. So that this interception body can be integrated into the passive safety belt system more effectively, one end of the holding belt for the interception body is to be fastenable to that end of the passive safety belt which is wound on a winding device, fastening to take place at a point which, in the depositing position of the safety belt, is situated immediately in front of the point at which the belt runs onto the winding device. The other end of the holding belt is to be fastened to the vehicle body, advantageously to a guide element which is held in a longitudinally adjustable fashion on a seat rail and can be connected to one leg of the vehicle seat.

Title: Method for operating a hybrid vehicle
Inventor: SEIFFERT ULRICH DR
IPC: B60L50/15
Filed: 1981-03-30
Abstract: The invention relates to a method for operating a hybrid vehicle with a combustion engine and an electric motor which can be fed from an electric energy accumulator, the electric motor acting in a lower performance range or speed range as the drive unit and the internal combustion engine acting in an adjacent upper performance range or speed range as the drive unit. In order to optimise consumption, switching over from the electric motor to the internal combustion engine is performed as a function of the daily expected distance covered by the hybrid vehicle with a power value and speed value which are lower for a relatively large daily distance than for a relatively short daily distance, specifically in such a way that on the one hand the electric energy accumulator is at least virtually discharged at the end of the daily distance covered and, on the other hand, the discharging is distributed at least virtually over the entire daily distance covered.

Title: Connecting terminal
Inventor: MACK GERHARD
IPC: H01R4/30
Filed: 1981-04-08
Abstract: The invention relates to a connecting terminal for electrically conductive round rods. The terminal in this case consists of a clamping body, which is bent from sheet metal and has a clamping groove (1) which is constructed for accommodating the end (8) of the rod, an end wall (6) which is provided with a threaded hole (9) for screwing in a terminal screw (10) parallel to the rod axis, and a force transmission device, which is adjustable by means of the terminal screw (10), for clamping in the end (8) of the rod. In order to design the terminal to be as simple and cheap as possible for mass production as a structural unit, the force transmission device is in this case formed by an end wall (5), which is bent up at the insertion end of the clamping groove (1) and has a through-hole (7), which is proud of the groove base (2), for insertion of the round rod (8). The terminal screw (10) is guided closely over the end (8) of the rod and its length is dimensioned such that the rod end (8) is tilted in the through-hole (7) when the screw tip (12) presses against the rear end wall (5) of the end (8) of the rod. <IMAGE>

Title: Sail and reefing system for commercial shipping
Inventor: FUHRMEISTER PETER
IPC: B63H9/10
Filed: 1981-05-21
Abstract: The total sail area is split up into a rigid portion, the rotatable profiled masts without stays, and semi-rigid, e.g. canvas, sails. The semi-rigid sails are held via end discs - the curvature is preset - fastened to the profiled mast or via booms - the curvature of the sail is adjustable - rotatably mounted on the mast. The reefing or setting of the semi-rigid sail area portion can be infinitely varied in each case via a reefing device arranged in the profiled mast. The reefing and setting of the semi-rigid sail area portion, the setting of the total sail area and the slewing of the booms can be effected automatically, i.e. automatic operation of the sails can be realised. Very high efficiency of the sails on all courses to the wind as well as a high degree of security and operational readiness distinguish the developed sail and reefing system. Depending on the requirements, it can be used as an auxiliary or main drive.
Patent DE-3120845-A1 (DE)
Title: Metal-cutting circular saw
Inventor: STURSBERG BERND
IPC: B23D45/14
Filed: 1981-05-26
Abstract: The novel metal-cutting circular saw provides for a fixed stop construction for workpieces to be cut, opposite which the machine frame can be set with a linear guide of the saw blade to various mitre-cut angles and for this purpose is pivotable. The likewise fixed work table of known embodiments is replaced by plates which are connected to the machine frame, penetrate into a gap in the stop construction and are movable in this gap with the machine frame so that the plates permit full support of even short workpiece sections in a parallel and tight arrangement on both sides of the cutting line of the saw blade. By a central hydraulic device, for the purpose of fixing the machine frame relative to the stop construction, the force applied by the pressure fluid can be transmitted to a concentric sliding ring, but constructed with substantially larger diameter than the hydraulic device, as a clamping force to a plate of the machine frame and can thus be used especially effectively for the purpose of clamping.

Title: Method for forming sheet-metal parts as well as device for implementing the method
Inventor: BECK WERNER
IPC: B21D26/02
Filed: 1981-06-27
Abstract: The invention relates to a method for forming sheet-metal parts, which consist of materials with a great dependency of the yield stress on the forming speed, by means of acting upon them with pressure. It also relates to a device for implementing this method. In this method, the workpiece to be formed is clamped in a forming chamber which is as a result divided into two spaces. While one, the working space, is connected to a pressure-medium container, the other, the forming space, forms a hollow shape which is connected to an aerating system. During the forming process, the working pressure set up in the working space is constantly adapted to the actual degree of deformation of the workpiece, by the gas displaced from the forming space by the workpiece being deformed being detected and measured and this measurement value being supplied as input signal to a control device which sets the respective working pressure. As measuring device, a flow meter can be used, in which the gas bubbles rising in a liquid column are recorded.
Patent DE-3127600-A1 (DE)
Inventor: RATHGEBER MAY
IPC: H04B14/04
Filed: 1981-07-13
Abstract: A process, and a device for carrying out the process, is provided for coding pulse-amplitude modulated signals into PCM signals in accordance with an approximated logarithmic characteristic curve. In the process, a partial coding characteristic curve which possesses a substantially reduced dynamic scope is first produced in a known manner. In accordance with the invention, a second pre-decision is carried out which subdivides the dynamic region of the partial coding characteristic curve into two sub-regions in such a manner that the coding of the lower and upper sub-regions is effected with the same number of weighting steps. This saves one weighting step with respect to prior processes.

Title: Process and apparatus for covering flat bar structures on both sides with plastic films
Inventor: CARL HEINZ ING GRAD
IPC: B29C65/00
Filed: 1981-09-28
Abstract: The invention relates to a process and an apparatus for covering bar structures, such as frames, with heat-shrinkable film of plastic. Bar structures covered on both sides are subjected at opposite points to a stream of hot gas, the kinetic energy of which presses the film, which has been transformed into a viscous state, together in the region of the windows between the bars of the bar structure, so that an integral bond is obtained. This allows permanent sheathings of bar structures with plastic film to be produced. The invention envisages in particular the processing of frame-like bar structures in a continuous process, the latter taking along an endless film web which is drawn off two film supply rolls arranged on both sides of bar structures conveyed away. After this, they are subjected to the streams of hot gas on both sides and, following cooling, during further conveyance, the welded-together film webs can be cut between two bar structures in each case and the bar structures can then be further conveyed individually.
