Title: Gear case for turn-and-tilt fittings
Inventor: HOELZL MANFRED
IPC: E05D15/52
Filed: 1982-09-23
Abstract: To simplify the production of a gear case for turn-and-tilt fittings, especially connecting-rod gears for rotary-handle actuation, comprising two case half-shells having bores for fastening the rotary handle, and nevertheless to allow a screw connection with the rotary handle, at least one of the bores of one housing half-shell possesses a thread over one half of a sleeve which is divided in two longitudinally and is in one piece with the housing half-shell and the other half of which is part of the opposite bore of the other housing half-shell. A thread can also be injection-moulded in one sleeve half without particular difficulty, since an appropriate tool having a thread on its end face can be pushed in laterally and be withdrawn again. The housing half-shell therefore already comes equipped with a thread from the injection-moulding machine.

Title: Track laying vehicle with hydraulic tensioning device
Inventor: NEYMANS HELMUT
IPC: B62D55/30
Filed: 1982-12-14
Abstract: The track laying vehicle has a hydraulic tensioning device for the crawlers (1). The tensioning device contains a valve arrangement (21, 27, 36) which keeps the hydraulic pressure in the tensioning cylinder (10) between a lower pretensioning pressure (po) and an admissible pressure. The respective admissible pressure is higher than the pretensioning pressure (po) by a fixed value during forward travel (V). During reverse travel (R) the admissible pressure is respectively higher than the pressure caused by the drive moment (Md) of the tumbler (2) in each case by a fixed pressure. For this purpose, the signal (Ep) originating from a pressure signal generator (40) connected during reverse travel (R) to the pressure line (19) of the hydraulic motor (16) is amplified as a function of the respective expulsion volume (Vg) of the hydraulic motor (16) and supplied to the precontrol part of the pressure limiting valve (36). <IMAGE>

Title: Threshing appliance for the processing of crops, especially maize
Inventor: GSCHWIND PETER
IPC: A01F12/24
Filed: 1983-02-02
Abstract: The invention relates to a threshing appliance, consisting of a threshing drum and of a threshing basket, with threshing-basket strips or threshing-basket round strips, extending transversely relative to the direction of throughflow, for the threshing of seed maize and corncob mix. With only one threshing basket, seed maize, such as corncob mix, can, in the shortest possible conversion time, be harvested selectively with low or high and with comminuted or coarse cob fractions, but also without the husk leaves surrounding the maize ear. All cobs can be harvested, without any loss, by means of this threshing appliance. The threshing appliance consists of a threshing drum, driven in the anti-clockwise direction, and of a threshing basket. Between the basket cheeks forming the lateral limitation of the threshing basket are inserted threshing-basket strips or threshing-basket round strips which extend transversely relative to the direction of throughflow of the maize crop. In the rear region of the threshing basket, one or more threshing-basket strips or threshing-basket round strips can be drawn out of the basket cheeks. The spacing between the individual threshing-basket strips/threshing-basket round strips is thereby increased, so that in the harvesting of corncob mix, as required, a few or all cobs necessary for obtaining a high-quality animal fodder can fall through these gaps. For the threshing of seed maize, in which the cobs are not also to be harvested, the threshing-basket strips/threshing-basket round strips can ... Original abstract incomplete.

Title: Hydraulic loop for extraction of urinary calculi in the ureter
Inventor: SCHLAMMINGER LUDWIG ING GRAD
IPC: A61B17/00
Filed: 1983-03-14
Abstract: Instrumental loop extraction of movable concrements in any ureteral deposits is conducted with a hydraulically characterized transport method free of complications. The radial "ventilation" of the ureter is externally preselected with an aseptic pressurized liquid both for passage of the catheter for loop formation and for manual transportation. Controllable liquid surges independent of the loop traction automatically assist transportation of the concrements, so that the usual risk of injury is prevented, the residence time of the catheter in the ureter is reduced and, finally, the individual traction load on the ureter by the physician can be physically controlled at any time to the advantage of the patient.

Title: Compact, miniaturised, optical spectrum analyser as a monitor for semiconductor laser light sources
Inventor: KIST RAINER DIPL PHYS DR
IPC: G02F1/03
Filed: 1983-03-31
Abstract: The device consists of a miniaturised Fabry-Perot resonator which is produced either from a monomode fibre or from an integrated optical waveguide. The resonator mirrors are directly applied. The tuning of the resonator is performed either via the temperature or - in the event of the use of electrooptical materials - via electric fields. This Fabry-Perot resonator serves for monitoring spectra of semiconductor laser diodes. For this purpose, e.g. the light signal emitted by the Fabry-Perot resonator is converted via a photodetector into an electrical signal and controlled via a suitable control loop of the injection current of the semiconductor laser. Different resolutions can be achieved and matched to the particular task by appropriate selection of the dimensions of the Fabry-Perot resonator.

Title: Hydraulic antilock brake system for vehicles
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/40
Filed: 1983-05-19
Abstract: The antilock brake system permits the repeated operation of a wheel brake (1) of a vehicle in a rapid first stage, which is followed by a slower second stage. This is achieved by a control piston arrangement (6) with a first piston (7) and a second piston (8) of larger effective surface than that of the first piston (7). The two pistons (7 and 8) move together as one unit during the second stage, but in the first stage the first piston (7) moves relative to the second piston (8). The movement of the pistons (7 and 8) is determined in the second stage by the difference between the effective surfaces of the two pistons (7 and 8) and by the magnitude of a throttle opening (27) which damps the return movement of the piston arrangement (6). <IMAGE>

Title: Method and device for shooting simulation
Inventor: FRANCKE ERWIN
IPC: F41G3/26
Filed: 1983-08-17
Abstract: What is described is a shooting-simulation method for training in shooting, especially for tank gunners, which allows an exact evaluation of the respective shot including its prehistory, permits an exact judgement of the hit location and, even under manoeuvre conditions, guarantees simple assessment. Care is taken, at the same time, to ensure that each target emits a characteristic radiation which, together with the target image, is recorded by means of a television camera and transmitted to a central station. The signals received also contain the codeable characteristics for identifying the vehicle supplying the target image, so that, when the cross hairs are located on the target at the moment of firing, a hit recognition can take place and, if appropriate, a smoke charge can be ignited at the target by means of a coded radio command.

Title: Method and circuit arrangement for determining the remaining distance which can be covered by a battery-driven electric vehicle
Inventor: BOETTGER KLAUS DR ING
IPC: B60L11/18
Filed: 1983-09-17
Abstract: In order to determine, at a particular instance, the remaining distance which can still be covered by an electric vehicle driven by an accumulator battery (6) assuming drive power and speed remain the same, on the one hand a variable which is proportional to the respective remaining discharge time of the battery still available and on the other hand a variable which is proportional to the instantaneous speed of the electric vehicle are formed, in a manner known per se, on the basis of the respective battery current (IB) and the preceding charge and/or discharge of the battery (6). The two variables are multiplied together in a multiplier (11). A display device (12) which indicates the remaining distance which can be covered is connected to the output of the multiplier (11). The additional influencing variables of the battery which are important during travel mode, namely the temperature, age and self-discharging of the battery, are taken into account additively during the determination of the remaining discharge time. <IMAGE>

Title: Apparatus for the treatment of liquid manure stored in an annular channel
Inventor: ZEISLER HANS
IPC: A01C3/02
Filed: 1983-10-24
Abstract: Liquid manure collected and stored in an annular channel underneath a stable floor has to be circulated and aerated at more or less regular time intervals, a comminution of solid fractions taking place at the same time in order to prevent the formation of surface scum. To make it possible to install an apparatus for the treatment of liquid manure even when the annular channel is filled and, in particular, to simplify the removal and installation of the apparatus during the elimination of operating faults, for example caused by clogging, it is proposed that the connecting line between the circulating and aerating pump and the ejection nozzle be shifted upwards at least approximately level with the plane of the stable floor and can be made separable in a simple way, and that, furthermore, the ejection nozzle be inserted into the orifice of a bulkhead wall shutting off the annular channel.

Title: Air distributing element in the form of a so-called nozzle crown, especially for arrangement on downward-directed blow-in pipes in poultry farm buildings or the like
Inventor: FRANDSEN HENNING
IPC: F24F6/14
Filed: 1983-11-30
Abstract: The nozzle crown for poultry farm buildings and similar locations has the upper edges (12) of nozzle openings, running obliquely outwards and also obliquely downwards, stamped from nozzle channels, open upwards and projecting from inner nozzle openings (12). The upper edges (20) of the side walls are mutually connected together in the triangular-shaped interspace between each two adjacent nozzle channels by an upper plate (22) which also runs obliquely outwards and obliquely downwards. Air streams blown out from nozzle openings (12) influence the room air of the triangular-shaped spaces above the upper plates (22) for effective entrainment from these regions, so that not only are powerful streams blown out from the nozzles (12,18), but more weaker streams are also emitted into the interspaces between the strong streams. A suitable uniformity of air distribution can be achieved over the whole floor surface lying below. <IMAGE>
Patent DE-3344707-A1 (DE)
Title: Passenger seat with a downwardly swivellable arm rest
Inventor: GALLITZENDOERFER JOSEPH PROF
IPC: B60N2/75
Filed: 1983-12-10
Abstract: A passenger seat is provided with a swivellable arm rest which is held in an articulated fashion by an arm rest carrier which bounds the seat laterally. In order to move the arm rest into the out-of-use position, the arm rest is initially raised, the ratchet of a ratchet-type locking mechanism leaving an associated engagement recess and remaining in the deflected position by means of an over dead-centre position spring. During the subsequent swivelling down of the arm rest, the ratchet moves over the engagement recess and before reaching the out-of-use position strikes a stop which reverses the ratchet, the latter being pushed into a lower engagement recess by means of the over dead-centre position spring which becomes effective in its other direction of action, which recess is less deep than the other engagement recess so that during a renewed upward movement of the arm rest the ratchet is not reversed on leaving the lower ratchet.

Title: Casting machine for producing an insulating element
Inventor: SCHMIDT MOGENS FALCK
IPC: B28B23/00
Filed: 1983-12-10
Abstract: A casting machine for producing an insulating element, in particular a construction board consisting of an adhesive compound, for example cement or gypsum, surrounding hollow polymer grains of low weight by volume in a coherent phase, consists of a mould which is orthogonal and is held with one edge downwards and with the side edges at an inclination of preferably approximately 45 DEG  to the horizontal. The mould is filled with adhesive compound from the lower part of the mould cavity. Since the mould consists of two parts which are separable from the lower edge of the mould up to its upper edge along an essentially diagonal plane, and the upper mould part is pivotable at the upper edge about a horizontal axis, problems in sealing the mould are avoided, the demoulding of the cast element being simple.
