Patent DE-3235149-A1 (DE)
Title: Instant picture camera
Inventor: MUELLER HANS MAX DIPL ING DR
IPC: G03B17/34
Filed: 1982-09-23
Abstract: In an instant picture folding camera, upon the pivoting-out of the lens carrier (3) into its position of use a scanning device (11, 13, 14) is controlled by means of a release slider (17) drivingly connected to the lens carrier, in such a manner that in the first instance a scanning lever (11) projecting into the cassette-receiving space (2f) pivots over the extraction slot (5c), which is covered in a lightproof manner, of a new cassette (5) and subsequently is pivoted back by means of a lever arrangement (13, 14) out of the region of the extraction slot (5c) and actuates a motor switch (18) situated in the pivot path. In order to extract the cassette-side cover sheet (5b) designed to be rigid, the slot cover foil (5d) is swung up. By means of the control pin (19a) of a revolving control disc, the scanning lever (11) is then again brought out of engagement with the switch (18). If the cassette (5) in the dark chamber of the camera is removed and is later reinserted, then upon the pivoting-out of the lens carrier (3) the scanning lever released by the release slider (17) pivots only as far as the slot cover foil (5d) which has been swung up, and is pivoted by means of the lever arrangement (12, 14) out of the extraction slot region again, but without actuating the motor switch (18). The motor is now energised upon the actuation of the camera release mechanism. <IMAGE>

Title: Hydraulically controllable shut-off valve, especially for securing a pipe fracture
Inventor: DISTLER JOSEF ING GRAD
IPC: F16K17/26
Filed: 1982-10-28
Abstract: A hydraulically controllable shut-off valve, especially for securing a pipe fracture, has a closing element (18) on which the force of a closing spring (19) acts and which monitors a pressure-medium passage (2, 11, 12, 20 to 23), and a control piston (3) which is arranged coaxially with respect to the closing element. In order to create a shut-off valve in which the closing element can be lifted off its valve seat only in a single through-flow direction of the pressure medium, the control piston is of hollow construction and holds the closing element in its cavity, at least in the region of its seating part (17), which cavity is part of the pressure-medium passage. Passage holes (11, 12 and 14 to 16) which are arranged at an axial distance from one another and on both sides of the valve seat (13) of the control piston, are provided in the outline of the control piston (Figure 1).

Title: Control apparatus for a crane attachment
Inventor: MAKINO KAZUHIRO
IPC: B66C13/08
Filed: 1982-11-09
Abstract: The control apparatus for a crane attachment has a winch which sits on a travelling crab of the crane, a multiplicity of first rope pulleys which are held on the travelling crab, and also a multiplicity of second rope pulleys which are held on the attachment. For movement, a movable block is arranged in the centre section of the attachment. Furthermore, a multiplicity of ropes for unwinding from the winch are provided. The ropes running off from the winch are first of all run over the second rope pulleys and then over the first rope pulleys and then, starting from there, are run to the movable block in such a way that, with regard to the crane, they are inclined to the front and rear as well as to the left and right. The apparatus is constructed in such a way that the pivoting movement of the attachment to the front and rear as well as to the left and right can be prevented by the ropes inclined in the manner described. At the same time, the position of the attachment during lifting can be varied by changing the tension equilibrium of the ropes on account of the movement of the movable block. <IMAGE>

Title: Multi-plate clutch
Inventor: RUEGGEN WERNER
IPC: F16D13/64
Filed: 1983-03-15
Abstract: A description is given of a multi-plate clutch which comprises two clutch halves which can be rotated relative to one another, each of which is rotationally connected to clutch plates and of which one is provided with a thrust ring which is axially displaceable relative to a stop ring, under spring force presses the associated areas of the clutch plates of both clutch halves against one another and, when subjected to pressure, releases the clutch. In this arrangement, the clutch plates are each firmly connected to their respective clutch half at a predetermined axial spacing matched to the thickness of the clutch plates of the other clutch half and they are designed as axially deformable diaphragm rings. This configuration brings with it the advantage that the clutch plates do not have to be guided in tooth systems. The backlash arising with toothed clutch plates is therefore avoided.

Title: Teeth model and method of producing dental prosthesis parts
Inventor: ZEISER MANFRED P DR
IPC: A61C9/00
Filed: 1983-04-29
Abstract: In a teeth model the intention is to fix individual part-regions of a block, on which tooth stumps made from a modelling material are fixed by pins, via retaining elements on a base in a defined and reproducible position. In such a model (saw model) a dental prosthesis part fixed on the tooth stumps can also be worked from the underside of the model because model sections including the associated block part-regions can be removed, but can subsequently be fixed again in the correct position on the base. This permits the dental prosthesis parts to be worked on the model with a spark erosion process using a wire electrode.

Title: Hanging device
Inventor: WANZL RUDOLF
IPC: A47F7/24
Filed: 1983-05-13
Abstract: In known hanging devices, a U-shaped hanger of the article bearer grips around the flat oval tube. The disadvantage of such hanging devices is seen in the fact that the article bearers can easily drop from the flat oval tube when they are jolted. The hanging device (1) proposed avoids this disadvantage in that the hanger (9) of the article bearer (7) grips around the flat oval tube (2) by more than 180 DEG  whilst utilising a flexible positive fit. <IMAGE>

Title: Regulated chimney-draft limiter
Inventor: WOLLANK GERHARD PROF DIPL PHYS
IPC: F23N3/04
Filed: 1984-02-27
Abstract: The method and the chimney-draft limiter operating in accordance with this method allow the chimney draft (p) to be held to an optimum, adjustable value by means of a motor-driven exhaust-gas flap (2) and to switch the furnace (1), especially a gas furnace, on and off. A measurement sensor and converter (3) detects the chimney draft (p) between the exhaust-gas flap (2) and the furnace (1) by means of a bridge circuit which contains two temperature-dependent resistors (11, 12). The one temperature-dependent resistor (11) is provided with a heat sink and is heated by the bridge current to a temperature of, for example, 120 DEG C. The other temperature-dependent resistor (12), which is heated in a corresponding manner, is cooled by flowing air which is drawn through a thin tube (15) containing this resistor (12) at a speed (v) which is dependent on the chimney draft (p). The exhaust-gas flap (2) is adjusted via an actuating motor (8) by a control and regulating device (7) in such a manner that the bridge is balanced. The desired value of the chimney draft can be adjusted by means of a screw (16) which extends into the tube (15). Furthermore, devices are provided in order not to switch the chimney-draft regulation on until the furnace (1) is fully in use and in order to switch the furnace off when the exhaust-gas flap (2) should be closed or the exhaust gases escape in the event of a defect. <IMAGE>
