Patent DE-3219698-A1 (DE)
Title: Drive motor for space vehicles
Inventor: MORITZ RICHARD
IPC: B64D27/24
Filed: 1982-05-26
Abstract: The drive is used especially for accelerating space vehicles. The drive motor consists of a plurality of drive motors according to Patent Application P 3100032.0-22, which are operated via a common controller. The masses (3) which are mounted on the mass supports (1) in each case generate the thrust forces. The angle monitoring apparatuses (5) which are fitted to the axes of the mass supports (1) determine the respective position of the masses (3) and report to the controller. This compares them with the respective program and carries out the necessary corrections in order to achieve an ideal curve shape. The individual drives can describe both a complete circular movement (at different speeds) as well as a partial circular movement. They can thus accelerate, for example, from -90 DEG  at V=0 to 0 DEG  at V=max., and decelerate again back to V=0 from 0 DEG  to +90 DEG . In the next phase, the movement takes place in the reverse direction. In the case of a circular movement, at least three individual drives must be connected together in order to compensate for the force components acting in the opposite direction. The initial speed V0 must be greater than 0. The individual drives must be shifted with respect to one another in their response by in each case tg/3. This also applies for partial circular movements of more than 180 DEG . In the case of partial circular movements of less than 180 DEG , two individual drives are sufficient, whose masses must be displaced with respect to one another in their response by in each case half the partial circle. <IMAGE>

Title: Strip steel cutter
Inventor: KARBACH HELMUT
IPC: B26D7/18
Filed: 1982-06-11
Abstract: The invention relates to a strip steel cutter, comprising a wooden board and a strip blade, which is provided with a novel ejector device. As ejector, resiliently mounted ejector pins are used, which are individually driven into the wooden board, since they are designed as nails on one side. They have the advantage that they are very cheap, can be rapidly assembled and for the punching out of parts made of deep-drawn thermoplastics films, there is no danger of these parts being damaged. The invention is characteristically illustrated by Figure 1. <IMAGE>

Title: Apparatus for cleaning bottles
Inventor: HEIDENREICH ERNST
IPC: B08B9/30
Filed: 1982-06-19
Abstract: The invention relates to an apparatus for cleaning bottles (1) which pass through a lye bath (20) in their transport containers (2) and are then turned through 180 DEG  by a guideway (6) and guided, upside-down, through cleaning stations (16) and, if necessary, through drying stations in such a way that the bottles (1) slip out of their transport containers (2) only up to a point where the bottle openings (111) rest on frustoconical fixing rings (7) and are centred in these conical fixing rings (7) in a simple way. These fixing rings (7) are fastened to transverse bars (18) between the transport chains (3) so as to be able to pivot in pivot bearings (17) in such a way that both precise centring of the bottles (1) in the cleaning stations (16) and problem-free release of the cleaned bottles (1) at the end of the cleaning apparatus, which works trouble-free and preserves the bottles, is ensured. <IMAGE>

Title: Clamping device on two suction pipes which can slide one inside the other
Inventor: STETTNER GERHARD DIPL ING
IPC: A47L9/24
Filed: 1982-07-24
Abstract: A clamping device for two suction pipes which can slide one inside the other has a clamping ring (10) which is fitted tightly onto the outer surface of the inner suction pipe (2), is rotatable thereon and can be screwed with a counter-threaded piece (6) into a correspondingly widened end, provided with a threaded piece (3), of the outer suction pipe. In order that no auxiliary air flow which can lead to contamination can be sucked in through the threaded connection, a cylindrical pipe continuation (11) is moulded onto the screw-threaded piece (3) towards the free end, the inside diameter of which pipe continuation is greater than the thread diameter. Additionally, an annular groove (12), in which an O-ring seal (13) is placed, is arranged in the clamping ring (10) adjoining the threaded piece (6) in the overlapping region of the pipe continuation (11). When the threaded connection has been screwed together, the O-ring seal (13) comes into sealing contact with the inside diameter of the pipe continuation (11). <IMAGE>

Title: Air heating system
Inventor: UNKEL DIETER
IPC: F24D11/00
Filed: 1982-08-14
Abstract: An air heating system has, as a heat source, a heat exchanger which is acted on by the surplus heat withdrawn from an adjacent room, and is especially suited to the heating of living quarters in agricultural establishments since the stables of such establishments must be constantly ventilated and the resulting exhaust air has a sufficiently high temperature to be able to be used in the heat exchanger.
Patent DE-3232243-A1 (DE)
Title: Circuit arrangement for assisted positive end-expiratory pressure ventilation
Inventor: JEHMLICH KLAUS DIPL ING DR RER
IPC: A61M16/00
Filed: 1982-08-30
Abstract: The invention relates to a circuit arrangement for assisted positive end-expiratory pressure ventilation (PEEPV) which implements response to small differential pressures in the respiratory system and thus permits an optimum intrinsic breathing rhythm with regard to frequency and breathing time quotient and minute ventilation. The circuit arrangement implements assisted positive end-expiratory pressure ventilation as a necessary transitional stage via intermittent forced ventilation to spontaneous breathing of the patient. This object is achieved, according to the invention, in that the circuit arrangement for assisted PEEPV has a delay circuit which is connected, on the one hand, with the control of the respirator and, has, on the other hand, a connection to a differential pressure transducer and the respiratory system of the patient.

Patent DE-3238220-A1 (DE)
Title: Device for changing the heat content of a fluid
Inventor: ALTMANN UWE
IPC: F01P3/20
Filed: 1982-10-15
Abstract: The device for heating and cooling an operating medium, for example the cooling fluid of an internal combustion engine, has a housing (15), in which a precontrolled pressure-limiting valve (22) and a slide valve (77) are arranged. A displacement pump (10) driven by the internal combustion engine (11) supplies operating medium to the device, where the medium, as long as it is still cool, is heated at the precontrolled pressure-limiting valve (22). When the desired temperature is reached, the pressure-limiting valve is put out of operation. The cooling fluid flows to a hydraulic motor (64) which drives a ventilator (65). This interacts with a heat exchanger (66), through which the cooling fluid flows. If the latter heats up to a fixed temperature, a second expansion-material element (68) then switches the slide valve (77) into such a position that all cooling fluid delivered by the displacement pump flows to the hydraulic motor so that the latter cools the fluid to a greater extent. <IMAGE>
Patent DE-3243552-A1 (DE)
Title: Thermostatically controlled setting device for heating valves
Inventor: KASPRIK MANFRED
IPC: G05D23/02
Filed: 1982-11-25
Abstract: The device has a sleeve-shaped lower portion which can be screwed to the valve, with an inner thread in the lower end for screwing to the valve and inserted above it an axially fixed but rotatable ring which has an internal polygon cooperating with the external polygon of the valve. A cap is externally pushed over the lower portion in a press fit, so that a given torque is transmitted by the cap to the lower portion. After the lower portion has been screwed onto the valve and the internal polygon has engaged over the external polygon of the valve, the lower portion is clamped against rotation with the ring. The torque produced by the press fit between the lower portion and the cap is large enough for the lower portion to be securely screwed onto the valve, but smaller than the torque produced by the clamping between the lower portion and the ring.
Patent DE-3247161-A1 (DE)
Title: Ski stick having a shock-absorbing arrangement
Inventor: LENHART KLAUS
IPC: A63C11/22
Filed: 1982-12-21
Abstract: In a ski stick, in the interior of the handle (19), the upper tube end (11) is axially displaceable, to be precise counter to the force of a compression spring (14) arranged in the handle (19). Stick (10) and handle (19) are thus longitudinally displaceable relative to one another, but they are prevented from rotating with respect to one another in that there is fastened non-rotatably on the handle (19) a hexagon-head screw (27, 28) which projects, with its head (18), into a cutout (16) which is located in the upper stick portion (11) and has a hexagonal cross-section. Said hexagon head (28) thus serves as a means for preventing rotation and, at the same time, as an axial stop. <IMAGE>
Patent DE-3248257-A1 (DE)
Title: Pressure control valve
Inventor: SCHLOTT WALTER ING GRAD
IPC: F02M69/54
Filed: 1982-12-28
Abstract: A pressure control valve (42) is proposed, which serves as part of a fuel injection system for influencing the fuel-air mixture of an internal combustion engine. The pressure control valve (42) has a movable valve part (45), on which a spring force (46), which can be influenced by a bimetal spring (50) of rectangular cross section, acts in the closing direction towards a fixed valve seat (44). The bimetal spring (50) is designed so that a natural frequency of the bimetal spring (50) results, which lies in a frequency range in which the lowest possible acceleration forces act when the internal combustion engine is running. <IMAGE>

Patent DE-3309518-A1 (DE)
Title: Separator for the separation of fine-grained and/or pulverulent particles from a gaseous medium
Inventor: AHLBERG WERNER
IPC: B07B9/02
Filed: 1983-03-17
Abstract: The name of the invention is CENTROSEPARATOR. It represents a construction based on centrifugal separation, for the separation of fine-grained and/or pulverulent particles from a gaseous medium. The advantage of the invention is that it replaces the cyclones which are used in many fields, and whose placement causes problems because of their size. The space otherwise required for a cyclone with the same output of medium is reduced to 1/3 by the compact design of the invention. The concept of the invention is to treat large quantities of medium in a smaller space according to the above features, and offer considerable advantages for installation, as well as to obtain a higher degree of separation than with a cyclone loaded with the same quantity of medium. The fields of use of the invention are all those in which large quantities of media have to be separated from particles of the above kind, such as, for example, over grate units (at 340 DEG C) or cooling units in the coffee industry, pellet coolers in the concentrated feed industry, or units for the cleaning or drying of cereal grains.

Patent DE-3317568-A1 (DE)
Title: Root-crop topper, especially beet topper
Inventor: RASMUSSEN HANS CARSTEN
IPC: A01D33/06
Filed: 1983-05-13
Abstract: On known beet toppers, the rotors have the same direction of rotation and the blower is attached to one side of the topper. For this reason, it is impossible to couple a truck, for receiving the beet tops, to the topper. The invention proposes a beet topper which can top two to six beet rows at a time, a truck being towed on the side of the topper on which the beet is already harvested. This ensures that the throw-blade rotors (1) for throwing the beet tops towards the middle of the topper where the blower (2) is attached have opposite directions of rotation. <IMAGE>
Patent DE-3319102-A1 (DE)
Title: Method for identifying objects, in particular fuel rods of a nuclear reactor, and device for carrying out the method
Inventor: HOELLER PAUL PROF DR PHIL
IPC: G21C17/06
Filed: 1983-05-26
Abstract: In order to identify fuel rods of a nuclear reactor, use is made of ultrasonic seals which consist of a polycrystalline material whose grain boundaries act, during exposure to ultrasound, as scattering centres, and effect reproducible scattering interference structures. By detecting and comparing the scattering interference structures of the high-frequency ultrasonic backscattered signals, it is possible to reidentify fuel rods which have been previously detected in the course of a zero recording of the reflectogram and provided with an ultrasonic seal. <IMAGE>
Patent DE-3320184-A1 (DE)
Title: Connecting element, in particular for the invisible connection of panel parts in furniture and method of producing the connecting element
Inventor: FISCHER WALTER
IPC: F16B12/04
Filed: 1983-06-03
Abstract: The connecting element according to the invention is introduced into cylindrical bores in the parts to be connected, so-called pearls of glue having previously been inserted in these bores. The connecting element consists of wood or of another statically stable expandable material and has a smaller diameter relative to the diameter of the bore holes. When the connecting element is pressed into the bores, the covering of the pearls of glue is destroyed by the tips arranged at the front and the adhesive released is distributed over the longitudinal grooves located on the outside of the connecting element, the adhesive surrounding the entire outer surface of the connecting element. During production, the cylindrical blank of the connecting element is compressed by a predetermined amount and, during this process, the profiles on the outside are simultaneously pressed in. The connecting element introduced into the bores absorbs some of the moisture of the adhesive and, in doing so, expands above the original dimension prior to compression, as a result of which an additional press-fit is achieved in the bore hole.
