Patent DE-3120611-A1 (DE)
Title: Device for radiating and for receiving focused ultrasonic waves
Inventor: LIERKE ERNST-GUENTER DIPL PHYS
IPC: G10K11/00
Filed: 1981-05-23
Abstract: In this device, a disc-shaped planar transducer (3) is coupled to a fluid chamber (1). In the fluid chamber (1), a second fluid enclosed between two elastic sound-transmitting diaphragms (6) is located, the velocity of sound of which differs from the velocity of sound in the fluid chamber (1). This forms a fluid lens (2), the focal length of which is variable by changing the fluid volume enclosed in it. Furthermore, the focus can be displaced in the focal plane, preferably by adjusting an optional angle of inclination of the planar transducer (3) with respect to the optical axis of the fluid lens (2). <IMAGE>

Title: Double-shell shoe
Inventor: ROMPPEL EDMUND
IPC: E04G17/00
Filed: 1981-05-29
Abstract: The invention relates to a double-shell shoe, usable primarily in one-sided formwork for concrete bottoms, but also suitable for smaller and medium lintel formwork. The article is illustrated in the drawing and consists of two box profiles which are welded against one another and have one or two open ends for inserting the jointly carrying wooden members. As a result of this type of pressure absorbtion, bracing is unnecessary. The storage is greatly simplified. The shoe is placed with the passage opening vertical, and a small stake is driven into the ground and wedged at the rear with a wooden wedge. A second wooden member is inserted horizontally from outside the building pit, which maintains the pressure. In the case of a hard subsoil, this can be carried out with a steel pin and wood. The building pit is thus free from braces and easily accessible. <IMAGE>

Patent DE-3127067-A1 (DE)
Title: Circle-arc bolt
Inventor: FRIESE PAUL
IPC: B60D1/02
Filed: 1981-07-09
Abstract: The invention relates to a development of coupling bolts in the known configuration with a securing pin for engaging behind tapered rings and similar configurations, in the arrangement of which the coupling bolt has a circular hand grip. In this arrangement, the securing pin is adapted to the circle arc of the hand grip in order to permit insertion into the hand grip during mounting. Special features are the circular configurations of the hand grip and of the securing pin, where, in dependence on the length of the hand grip, the circle arc is adapted to the angle required for engaging behind the tapered rings or similar configurations thereof. The circular configuration of the hand grip and its securing pin according to the invention provides, in a simple manner, a solution which does not hinder the attachments and the like on vehicles, without the securing of the coupling bolt losing its function. The circular configuration of the hand grip and its securing pin permits longer hand grips, it being possible for the end of the hand grip to be moved to desired spacings from, or positions with respect to, the bolt centre or beyond.

Patent DE-3221517-A1 (DE)
Title: Acoustic frightening device for preventing damage caused by game
Inventor: SCHMIDT REINHOLD
IPC: A01M29/16
Filed: 1982-06-07
Abstract: From the following description of the exemplary embodiments, the details of an invention emerge, with which wild animals are to be driven away or frightened away from agricultural cultivations by acoustically emitted signals. Fright sounds or warning cries of wild animals are to be recorded on an exchangeable sound carrier and emitted acoustically at continuously adjustable time intervals. The cough of a person or other sound frequencies recorded on the sound carrier could also be very effective. As damage caused by game occurs mainly at night, the device is to switch on and off automatically at preprogrammed times by means of a time switch, photocell or microprocessor. The necessary energy supply is to be carried out by a small accumulator. If it is called to mind that annual damage caused by game of a few thousand marks is not infrequent in many hunting areas, the importance can be recognised all the more of a reliable frightening device, as the usual scent-destroying means only provide a remedy for a short time, and pasture fences and other fencing-in systems are in most cases not possible and are moreover very expensive.
Patent DE-3221658-A1 (DE)
Title: Method and device for checking the tightening torque of screws and similar connecting elements
Inventor: SCHATZ JOHANN
IPC: B25B23/14
Filed: 1982-06-08
Abstract: In order to check the tightening torque of screws, the latter are turned further or loosened by means of a tool and the torque applied in the process is measured. According to the invention, an angle transmitter which is activated as a function of torque is used to detect the torsion arising, and the associated torques are then measured and stored in uniform angular increments. By representing the overall variation in torque and/or evaluation with the aid of a microprocessor, it is possible to obtain information on the tightening torque which is free from the random features of the breakaway torque. A device for carrying out the method comprises a screwing tool with a torque meter, an angle transmitter for detecting the angle of rotation relative to a fixed reference, and an evaluation and display unit with a memory for the angular increments and associated torques and for displaying the variation in torque or at least its minimum value following breakaway.

Title: Slide holder
Inventor: KIRCH OSKAR
IPC: G03B21/64
Filed: 1982-07-30
Abstract: Starting from a non-glass-mounted slide frame having two flat, corresponding plastic frame halves which accommodate between them a film section whose film surface is visible through a window, the frame halves being capable of being plugged together by means of integrally formed-on connecting elements and having limiting pins for fixing the position of the film section, the aim is to improve the said slide frame in the simplest way so that the film section is retained in an optimum flat position. For this purpose, connecting elements located opposite one another in pairs, symmetrically in each case, are arranged in the outer frame region and four cam-like elevations are provided in a position rotated by 45 DEG . This produces a convex sag of each frame half towards the middle, which sag resiliently clamps the film section in the two frame halves.

IPC: B01J19/30
Filed: 1982-12-04
Abstract: Spherical packings, stamped out from a thin, flat plate, for matter and heat exchange columns have strips running in a meridional fashion, which pass into a ring running along a circle of latitude. In order to achieve a stamped packing substantially conforming to the spherical shape, which still has favourable baffles within its shell, on the basis of the invention, the ring is located in the equator of the packing. The meridional strips proceed from this ring. At the pole, they are then curved inwards, where these bends can have tongues or similar additional deformations, in order to multiply the baffles within the sphere.
