Patent DE-3012749-A1 (DE)
Title: Rectifier bridge with motor or generator load - has bridge arms formed by thyristors sequentially fired by quenching thyristors across bridge
Inventor: BEZOLD KARL-HEINZ
IPC: H02M7/162
Filed: 1980-03-28
Abstract: The rectifier bridge with a motor as a load, which can also act as a generator, has an input which can be the secondary winding of a mains transformer. This forms part of a rectifier bridge with a thyristor in each of its four arms. The motor is connected across the bridge in series with a choke coil. In parallel with the bridge are two quenching thyristors in series with two quenching capacitors. In parallel with the two capacitors are two charging diodes in series with a charging resistance. For feedback, the bridge is fully controlled, with two thyristors in diagonally opposite branches first fired. The other thyristor of one of the pairs of thyristors is excited after a time which can vary, to form an additional main branch of a free running circuit. With the ignition of a quenching thyristor the parallel branch is cut off, and the remaining thyristor is fired to form the second diagonal of the bridge for the next half wave.

Title: Logic control system for data processing installation - is contained in VDU to control data insertion or removal, or transfer between peripherals and memory
Inventor: RYAN JOSEPH L
IPC: G09G5/22
Filed: 1980-04-28
Abstract: Video line information is stored in a memory in a predetermined order. A logic control system controls memory allocation so that the information may be accessed withtou reconstruction of the original inforamtion. This allows lines of data to be inserted or removed. A visual display unit contains a synchronisation and control unit which generates the timing signals for a data bus address bus, and the control bus. The synchronisation is divided into an address and a data phase. Direct memory access cycles allow communication between peripherals and a memory and during CPU cycles the CPU operates. A screen controller operates during the direct memory access cycles to produce addressing signals for the memory. This allows information from the memory to be displayed which is continuously regenerated.

Title: Parent-satellite exchange channel processor interconnection - has dual secure PCM channels to interconnect shared facility parent exchange processor
Inventor: PALSA HELMUT
IPC: H04M7/06
Filed: 1980-04-29
Abstract: Transmission channels are used to connect parent and satellite telephone exchanges so that a data transfer between the common control equipment of the two exchanges can be used for control purposes, especially those of an energy saving nature. Registers in the parent exchange can be accessed by subscribers on both the parent and satellite exchange for signalling purposes. The objective is to make greater use of the common exchange equipment by providing greater access to it for subscribers on the parent and satellite exchanges. Each subscriber (T11,T12,T1m) on the parent exchange is connected via a line unit (Ta11) to the switch block (K) and the common control (AST). Multifrequency receivers (W1...Wx) are also connected to the switch block and the common control; both using a common data bus (P) for control purposes. A 2 Mbit/s 30 channel PCM path connects the parent and satellite exchanges. For security two 30 channel systems (G1,G2,G11,G12,g1,g2) carry 29 transmission channels and the 30th channel in each is used for a duplicated signalling path.

Title: Pile for reinforcing sub-soil - formed of coarse aggregate and binder hardening to open-pore cellular structure
Inventor: HELMDACH GUENTER
IPC: E02D5/46
Filed: 1980-09-08
Abstract: Subsoil is improved by means of piles, pillars or stays formed by introduction of a coarse material, e.g. sand, gravel or crushed rock, into holes in the ground, and addn. of a liq. binder which hardens to an open-pored cell structure. The binder is pref. a polyurethane, esp. a 2-component polyurethane consisting of a polyol and a diisocyanate. The vol. increase on foaming is 1:3-5, and the reaction time at 20 deg.C is not more than 30 mins. Final hardening takes 1-2 hrs. Catalysts may be added to shorten these times. The binder and aggregate may be put separately into the hole, or may be fed alternately in layers which are not too thick to allow mixing of the components. The aggregate may be vibrated and subjected to air pressure while the binder is being introduced. The coarse material may be pre-wetted with the binder, but must then be filled into the hole within 20 mins. Foundations with higher pressure and flexing strength are obtd. The cellular structure gives drainage. The structures are resistant to soil bacteria and to soft water. The binder penetrates partly into the soil, increasing the friction and reducing the danger of sinking.

Title: Internal combustion engine with exhaust gas recirculation and mixture control
Inventor: GOTOH OSAMU
IPC: F02M7/133
Filed: 1981-01-30
Abstract: An internal combustion engine for a motor vehicle has an exhaust gas recirculation system for returning exhaust gases into the intake port. The carburettor system comprises a fuel enrichment valve (6). Sensors for different speeds of travel and engine operating states actuate control valves, the action of which is modified by a sensor (Sa) for atmospheric pressure. In this way the fuel enrichment valve (6) and a valve (16) in the exhaust gas recirculation duct are controlled so that the fuel enrichment and the exhaust gas recirculation can both be reduced when the vehicle is operated at high altitude at low atmospheric pressure. <IMAGE>

Title: Hydraulic brake device for a tractor vehicle with trailer
Inventor: ZIRPS WILHELM
IPC: B60T13/58
Filed: 1981-03-19
Abstract: A hydraulic brake device (10) for a tractor vehicle (11) with trailer (12) is proposed, in which after braking of the accidentally separated trailer by means of pressure medium from an energy storage device (27) situated on the trailer side, the brake cylinders (24) of the trailer can be released again. A control element (39), loaded by a spring (49) in a reversing valve (21) actuated by a safety line (26) accommodates a pilot-controlled first non-return valve (54) and defines a pressure chamber (48), which can be connected by way of a second non-return valve (61) to the energy storage device (27). By way of a tappet (34) and a lever (69) the control element (39) can be driven as delivery piston of a pump (73), in order to deliver pressure medium from the brake cylinders (24) of the trailer (12) into the energy storage device (27) following emergency braking. When a trailer (12) is coupled up to the tractor vehicle (11) the tappet (34) holds the control element (39) in an operating position joining the two connections (19, 22), as a result of which a partial flow limited by a restrictor (59) flows by way of both non-return valves (52, 61) to the energy storage device (27) when braking and keeps the latter ready for operation. <IMAGE>

Patent DE-3121302-A1 (DE)
Title: Combustion engine
Inventor: DROESCHEL HELMUT
IPC: F02B75/02
Filed: 1981-05-29
Abstract: In the V engine two cylinders (1, 2) of small diameter (d) are here arranged on one side. On the other side is a cylinder (3) with large diameter (D) offset by 90 DEG  in relation to these, which comes into use only for high outputs. When idling or under partial load the right-hand carburettor (16) functions, the left-hand one (17) remains closed. Consequently only the two small pistons (13, 14) generate the output. The large piston (15) is idling. (If such a device is fitted its valves (19) are thereby also correspondingly transposed). From half throttle to full throttle the left-hand carburettor (17) also opens. The large, left-hand piston (15) now delivers power. At full throttle approximately 60% of the power is produced by the large piston (15) owing to the high performance characteristic of the valve control. Lower fuel consumption under partial load because the two small pistons are (almost) completely full and only 1 piston is unloaded. Compact, simple construction. Good balancing of masses and true running. Good idling due to regular ignition sequence 360 DEG  - 360 DEG . Idling adjustment necessary only on one of the two carburettors. Short intake distances. <IMAGE>

Patent DE-3138984-A1 (DE)
Title: Milling tool for shaping workpieces made of wood
Inventor: SCHMIDT ERICH ING
IPC: B27G13/08
Filed: 1981-09-30
Abstract: The invention relates to a milling tool for shaping workpieces made of wood, which is arranged on a drive shaft parallel to the axis of rotation of the workpiece and has a multiplicity of cutting teeth of at least one tooth shape, having main cutting edges cutting the circumferential face of the workpiece and/or secondary cutting edges cutting the end face of the workpiece, and is movable relative to the workpiece in the axial and radial feed direction. The invention is to provide a milling tool which, when shaping workpieces made of wood, permits an increase in the relative cutting speed and hence an improvement in the surface quality of the processed workpiece, without increased heat generation at the tool and at the workpiece occurring at the same time. In addition, the life of the tool should not be disadvantageously affected thereby. This is achieved by the fact that, as a result of a slight inclination of the drive shaft of the milling tool with respect to the axis of rotation of the workpiece in two planes situated vertically one on top of the other, a resulting rotational plane of the milling tool is adjustable in such a way that the cutting teeth recede from the cut surface after engagement on the workpiece.

Patent DE-3147042-A1 (DE)
Title: Bushing
IPC: G21C13/036
Filed: 1981-11-27
Abstract: Lines which pass through walls or building components which penetrate each other or are only in contact, must not be rigidly joined to one another for reasons of mobility. This applies in power stations, nuclear plants and chemical plants, where rooms have to be sealed from one another in a pressure-resistant, heat-resistant, fire-resistant, dust-resistant and radiation-tight manner which also allows decontamination. According to the invention, this is a bushing which employs thermal-physical or/and thermal-chemical means in order to guarantee permanent high heat resistance with good pressure resistance and dimensional stability, roughly analogously to DIN 4102, up to far beyond F 180. The multi-layer elements of flexible soft material making a seal between the wall and a process pipe consist of layers, which react in part thermally, in part physically and in part chemically, in the form of films of plastics, ceramic fibre fabrics, metal foils and metal fabrics and/or substances of the nature of resins or foams, which are interposed and at an upper limit temperature react at least partially and remove heat from the surroundings, for example heat of fusion, heat of vaporisation, and the like. Radioactive substances, chemically toxic substances and flue gases are retained by filter materials which are accommodated in cavities.
