Patent DE-3214664-A1 (DE)
Title: Method of ensuring the stability of a movable working stage, and a movable elevating working stage
Inventor: KREMER ERWIN ING GRAD
IPC: B66F17/00
Filed: 1982-04-21
Abstract: There are movable elevating working stages with a working platform which is vertically movable on an articulated mast relative to the bearing surface of the elevating working stage. In this arrangement, the articulated mast consists of at least two arms which can be adjusted in inclination in planes vertical to the bearing plane and are connected to one another in an articulated manner. In such elevating working stages, the angle between the bearing plane of the elevating working stage and the ideal horizontal plane, insofar as it impairs the stability, is to be compensated for by limiting the motion space of the boom system. To this end, the resulting inclination range of the articulated mast arms is corrected by the angle between the bearing plane of the elevating working stage and the ideal horizontal plane.
Patent DE-3216343-A1 (DE)
Title: Delivery nozzle
Inventor: CERBONI RENZO
IPC: A23G3/20
Filed: 1982-05-03
Abstract: Delivery nozzle for casting sheets for shaping of chocolate, etc. in high productivity plants, with a strip-shaped nozzle housing (2) which is stationary relative to the rotor (3) of the distributor valve and has two semicircular recesses (9) to each receive a shaft (11), which shafts (11) are supported below by strut elements (12) which separate from one another the individual feed spaces (7) of the delivery nozzle. Each shaft (11) is provided within the delivery nozzles with a flat (15), by means of which pivotable lamellas (17) are supported. When pivoting in the closing sense, the lamellas (17) simultaneously enlarge the feed space (7) located above. A cutting action on the chocolate fed in, and also damage to any hard ingredients such as nuts, etc. there may be, is thus completely prevented. The gap width of the delivery nozzle (1) is selectively adjustable by means which effect the pivoting motion of the shafts (11). <IMAGE>
Patent DE-3218181-A1 (DE)
Title: Oscillating armature drive and a method for operating an oscillating armature drive
Inventor: KIENZLER GERHARD
IPC: H02K33/12
Filed: 1982-05-14
Abstract: An oscillating armature drive having two stator electromagnets (3) (Fig. 2) and a spring-neutralised oscillating armature (4) has a controller (16) for alternating driving the stator electromagnets with DC current. The controller (16) is formed by two diodes (6, 7) of opposite polarity, when the oscillating armature drive is supplied from an AC network, the two windings (8) of the stator electromagnets being connected in parallel and these diodes in each case being connected in one of the supply lines to a winding (8). This results in alternate switching-on and activation of the stator electromagnets and hence in unambiguous polarisation, as a result of which there is no need for a polarised permanent magnet in the oscillating armature (4). The oscillating armature (4) can thus be of simpler construction, since only one corresponding pole shoe (9), consisting of soft magnetic material, is now required as the opposing pole to the stator electromagnets. In consequence, production tolerances affecting the drive power, which otherwise exist and are caused by the permanent magnets, are avoided. <IMAGE>

Patent DE-3308525-A1 (DE)
Title: Stepped manual transmission, especially for motor vehicles
Inventor: KLAUE HERMANN DR ING
IPC: B60W30/18
Filed: 1983-03-10
Abstract: The invention relates to a stepped manual transmission, especially for motor vehicles with an electronically controlled shift stage synchronisation. The transmission components serving for synchronisation are an input friction clutch necessary for separation from the drive train, a synchronising brake arranged in the drive train, a synchronising clutch driven by the output train, and gear shift sleeves located between the output gears. These transmission parts are operated by compressed air, intake air or hydraulic oil. The operation is controlled by an electronic control unit, which obtains data on the driving conditions of the vehicle from various measuring sensors. In the case of geometric shift stepping a speed sensor is provided for detection of the synchronous speed of rotation of the shifted gear and the gear to be shifted, which sensor registers the speed of rotation of the drive train. If different individual graduations are used, the speeds of rotation of all shiftable gears of the output train are detected by speed sensors. The transmission is equipped in particular with one or more auxiliary shafts on which the synchronising brake and clutch are arranged. <IMAGE>
Patent DE-3314591-A1 (DE)
IPC: B23B31/00
Filed: 1983-04-22
Abstract: A receiver body (1) carries a holder shaft as needed and has on one end face an abutment face (4), extending at right angles to the axis of rotation, and a coaxial, conical receiving bore (5). A connection part (14), which is preferably embodied as a tool carrier, likewise has on one end face an abutment face (15, 15'), extending at right angles to the axis of rotation, as well as a coaxial, conical centering stub (16) fitting into the conical receiving bore. In order to assure a high degree of concentric accuracy, even in the event of strong forces exerted laterally upon the connection part, the inner cone (6) surface of the receiving bore (15) has a cone angle that is larger by a predetermined, small difference angle (27) than the outer cone surface (17) of the centering stub (16). This difference angle is such that upon the insertion of the centering stub into the receiving bore, the outer cone comes into engagement with the inner cone surface first in the vicinity of its smallest diameter. At least one of the two cones is elastically deformable so that the two cones engage one another over essentially their entire length and face and provide for matching engagement of the abutment faces (4, 15).

Title: Device for producing slots in a dish-shaped body made of wood or plastic
Inventor: ROETTGEN PETER
IPC: B23D55/04
Filed: 1983-04-27
Abstract: In a device having a vertically guided, driven saw blade for producing slots in a dish-shaped body which consists of wood or plastic and can be fixed between two rotatably mounted clamping jaws which are arranged with their bearing blocks on a rotatably mounted slide, there is no possibility of providing the device with a guide for the saw blade owing to the fact that a spindle is guided in the two bearing blocks in order to adjust one clamping jaw. This disadvantage is eliminated in that the bearing block of one clamping jaw is displaceable on the slide of the device and there is mounted in the bearing block a hollow-cylindrical, axially fixed shaft which is provided with an internal thread and in which a manually actuable spindle is guided which, at its end projecting out of the bearing block, has a tapered pin on which the one clamping jaw is rotatably mounted, and in that the one clamping jaw is longitudinally displaceably connected to the hollow-cylindrical shaft.

A clear increase in the upper cut-off frequency of the spatially sensitive detector can be achieved by the following features:   a) the spatially sensitive detector consists of a graduated filter (V) and a downstream photodetector (P1), b) the graduated filter (V) is at least approximately in the image plane of the lens (L), c) the transmittance of the graduated filter (V) is variable in the direction (x') of the spatial coordinate (x) to be detected.   <IMAGE>
Patent DE-3319803-A1 (DE)
Title: Applicator device for the application of foamed liquor
Inventor: MITTER MATHIAS
IPC: D06B19/00
Filed: 1983-06-01
Abstract: The applicator device consists of an applicator tube which can be closed preferably adjustably at the end and is made to be fillable at the end from the endface and which is equipped on one of its end faces with an inflow connection for the application medium. Inside the applicator tube is arranged at least one displacement body reducing the foam throughflow cross-section. The displacement body is at a distance from the inner cylindrical surface of the applicator tube, and it can consist of one or more parts, but is preferably made smooth-walled and leaves a uniform distance from the inner cylindrical surface of the applicator tube. The resistance of the displacement body makes it necessary to give the inflow connection a very much larger cross-section than the outlet connection, which can be closed adjustably. The inflow connection is to be approximately in the ratio of 2:1 to the outlet connection, preferably higher than lower in this ratio. The essential factor is that a uniform continuous flow of the foamed application medium be conveyed from one side of the applicator device to the other, the volume inside the applicator tube being reduced by the displacement body, in order to prevent a curing of the foam. <IMAGE>

Patent DE-3332708-A1 (DE)
Title: Crank drive for window lifters
Inventor: BENDER EBERHARD
IPC: E05F11/50
Filed: 1983-09-10
Abstract: What is described is a crank drive for window lifters in motor vehicles, which makes do without the brake spring necessary in previous devices of the same type. This brake spring serves for preventing the window pane from being pressed down. In the invented device, the blocking of this movement is brought about by a toothing on the crankpin and by a like toothing on the driven pin, for example on the cable reel, these toothings engaging in one another in the position of rest of the device. When the crankpin is rotated to one side or the other, the engagement of the toothings is first released during an idle rotation of this pin and only thereafter is the driven pin taken up in rotation by the crankpin.
