Title: Gripping fixture which can be attached to motor-driven appliances
Inventor: HAAS EBERHARD
IPC: B24B41/06
Filed: 1984-10-02
Abstract: The invention relates to a gripping fixture which can be attached to motor-driven appliances and is intended for gripping tools (11), in particular used in surface finishing, such as files, scrapers and whetstones. It contains a pincer-like clamping device (2) which has at least one fixed, flat bearing surface (3) and, opposite this surface, a flat gripping surface (4) of a displaceable gripping element (5). The gripping element (5) has a flat clamping surface (6) on its side (29) remote from the gripping surface (4). The clamping device (2) has an inoperative position on the one hand, in which a tool (11) can be inserted, and an operative position on the other hand, in which the clamping surface (6) of the gripping element (5) is supported relative to a second fixed, flat bearing surface (7) and presses the tool (11) to be gripped in the direction of the first bearing surface (3) via the gripping element (5). <IMAGE>
Patent DE-3438673-A1 (DE)
Title: Overload protection for share ploughs
Inventor: EGGENMUELLER ALFRED DR ING
IPC: A01B61/04
Filed: 1984-10-22
Abstract: Overload protections as a rule react only to extreme impact stresses on the plough body. Resilient arrangements between the plough body 1 or only the share 5 and the holder 2, such as, for example, sliding guides 10 and 11 supported by springs 8 and 9, are proposed in order also to absorb the lower and medium impact stresses. Since these devices measure the magnitude of the force by means of the spring excursion directly at the place where the peak stresses occur, this springing can be utilised in order to trigger overload protections. For this purpose, the linkage 18 transmits the springing to the bolt 17 of the support 12 for the plough body 1 attached to the holder 2 which is connected in an articulated manner to the plough frame 3. With the release, the rod 16 is freed, so that the plough body 1 can shift upwards. The spring 13 brings the plough body 1 into the working position again. <IMAGE>

Patent DE-3520562-A1 (DE)
Inventor: DINSE WILHELM
IPC: B23K9/28
Filed: 1985-06-07
Abstract: A safety stoppage or disconnection apparatus for mechanically moved tools, particularly automatic welding guns, having a swashplate and an assembly casing, between which are arranged one or more spring elements and a switch operated by the relative movement between the swashplate and assembly casing. It is necessary with such safety apparatuses to prevent other adverse rotary movement between the swashplate and assembly casing. This is brought about by two facing bolts, whose heads projecting beyond the outer wall of the swashplate are guided in slots, which run in the inner wall of the assembly casing in the intended swashplate movement direction. The bolts are spring-loaded and preferably spherical. The bolts with the spherical heads on the one hand reliably prevent a rotary movement between the swashplate and assembly casing and on the other hand do not prevent the relative movement and a slowing down movement necessary for the operation of the switch, even if the swashplate is tilted and tipped by the relatively large moment exerted by the tool against the swashplate. Following tool relief, the swashplate returns in an unimpeded manner to its initial position.

Title: Pushbutton coupling for the releasable connection of dental components
Inventor: HADER HELMUT
IPC: A61C13/265
Filed: 1985-06-25
Abstract: A pushbutton coupling for the releasable connection of dental components first of all has an anchor shaped like a male mould and having a constricted outer surface area. This anchor is releasably received with snap locking in an eyelet resembling a female mould, the inner surface area of which is formed of two mutually coaxial truncated conical surface areas which merge into one another in their planes of smallest diameter. The eyelet is made of a circular cylindrical tubular section in which the inner surface area, at most, is processed with removal of material, especially ground and/or polished, for the purpose of shaping. While being simple and precise to manufacture, the eyelet permits reversible arrangement in order to achieve a resilient or rigid seat of the anchor in the eyelet.
Patent DE-3527633-A1 (DE)
Title: Moulding recovering shape whilst maintaining its spatial extent
IPC: B29C61/10
Filed: 1985-08-01
Abstract: In a moulding, in particular a sleeve having the shape of a cylinder envelope and made of thermoplastic, with a shape memory produced by crosslinking, in particular for enveloping application, with the supply of heat, onto articles which are essentially round in cross section, for example cables or pipes, the moulding having a continuous longitudinally extending separation point, the aim is to provide a solution which, in the case of mouldings of this generic type, makes specific closure systems for the separating point unnecessary and makes possible an economic production process for the mouldings. This is achieved in that the use-shape or fitting-shape of the moulding (5) is formed from an original moulding (1) having the shape memory, in particular from an extruded, if appropriate slit and cross-linked tube, by subsequent change of shape, preferably with the supply of heat. <IMAGE>

Patent DE-3604365-A1 (DE)
Title: Lifting appliance, in particular rope-tackle device for lifting, lowering and pulling loads
Inventor: HABEGGER WILLY
IPC: B66D3/02
Filed: 1986-02-12
Abstract: A lifting appliance for lifting and lowering loads, on the housing of which a load hook is rotatably mounted. Furthermore, the load hook is pivotably mounted about two pivot axes disposed at right angles to its rotation axis and to one another. In this respect a universally movable load-suspension point with a rotatable load hook is realised. In addition, the rotation and pivot axes are acted upon by brake elements in such a way that the load hook is braked in all positions just to such an extent that it stops in each desired position. This makes it considerably easier to put the lifting appliance into a rope loop, for example, even if the rope loop has considerable rigidity, because the preselected load-hook position is not changed by putting the lifting appliance into the rope loop. The load hook or the lifting appliance is automatically set in the correct position only when loading occurs. <IMAGE>

Title: Optical distance, shape and position detection sensor
Inventor: BARTHEL EGBERT DIPL ING
IPC: G01B11/26
Filed: 1986-04-02
Abstract: The optical contactless sensing device permits both the distance, the position and/or the shape of the sensed measured object to be determined within a certain measuring range. The device does not require any mechanical moving components. The object is achieved in that a structure is imaged on the object to be sensed by means of an astigmatically imaging optical system. In a plane which is conjugated with respect to the structural plane, image sensors with point-by-point resolution are arranged behind a structure which corresponds to the object structure. The image which is modulated by the object to be sensed is detected by them. In the case of the output signal sequences being suitably processed, distance, shape, and position of the object to be sensed can be inferred from them.

Title: Device for selecting certain receiving channels in a receiving device of entertainment electronics which can be tuned to receiving channels
Inventor: DURST KLAUS DIPL ING
IPC: H04N5/46
Filed: 1986-08-16
Abstract: The device (1) according to the invention for selecting certain receiving channels is constructed for selecting receiving channels in a number of transmission standards (I, II, III). For this purpose, it contains a receiving-channel memory (9) in which a data group with the associated tuning and operational adjustment data is allocated to each channel (K1 to Kn) of each transmission standard (I, II, III) and a storage location (12, 12') selectable by a channel selector (10) is provided for each of these data groups. Having clock pulses (16) at a first clock input (T1) of the channel selector (10), the channel selector selects each storage location (12, 12') in accordance with a certain arrangement. With clock pulses (21) at a second clock input (T2), the channel selector (10) successively selects only the storage locations (12') of data groups (D11, D21...) of a single, particularly a preferred transmission standard (I). As a result, a simple and rapid selection of a desired receiving channel (K3) in a particular transmission standard (III) is achieved by means of an operating device (8) and in conjunction with a display device (11).

Title: Connection of extruded sections
Inventor: HENSELER PETER
IPC: B21D39/03
Filed: 1986-12-24
Abstract: In the case of a connection of aluminium extruded sections by spreading into dovetail-shaped grooves, soft alloys and relatively high pressing forces have to be used in order to fill the gaps, resulting due to high manufacturing tolerances, such that a permanent connection is obtained. If the connections are produced by fitting together under pressure, local deformations on both visible surfaces of the sections are unavoidable. In addition to detracting from the appearance, this also entails technical disadvantages, e.g. sharp-edged elevations. The object of the invention is to permit a permanent connection of extruded sections, at least one side of the section connection remaining smooth-surfaced. The two extruded sections (1, 5) are plugged one into the other by their longitudinal edges, via a groove-and-tongue system, such that the base surfaces (3, 6) of the sections (1, 5) are precisely in alignment on one side of the connection location. The groove-and-tongue system is configured such that a cavity (16) is formed in the region of the connection location when the sections (1, 5) are plugged together. Material of one or both sections is pressed into this cavity (16) on one side and in a locally restricted manner, with the result that a positively locking connection is obtained. In this arrangement, that side of the extruded-section connection on which the base surfaces (3, 6) butt against one another in alignment remains undeformed and smooth-surfaced. Connection of aluminium extruded sections. <IMAGE>
