Patent DE-3151921-A1 (DE)
Title: Displaceable cutting wheel for edge-trimming machines
Inventor: ELLMANN MANFRED DIPL ING
IPC: B26D7/26
Filed: 1981-12-30
Abstract: To trim the edges of a sheet-like cutting material (for example, paper, foils, etc.), rotating cutting wheels have to run along fixed cutting edges and execute a drawing cut. In order to make it possible in a single operation to trim three or more edges of the cutting material simultaneously (synchronously), the cutting wheels must be guided with pinpoint accuracy from a catch location situated outside the cutting region up to the cutting-edge corners formed by the intersecting cutting lines. This takes place, according to the invention (see the drawing), in that the cutting wheel pressed axially towards the cutting edge by a compression spring is advanced exactly to the cutting-edge corner by means of a crown wheel arranged on the same shaft and running along an adjustable guide strip. <IMAGE>

Patent DE-3208233-A1 (DE)
Title: Device for pointwise determination of the give of upholstered seats and backrests subjected to loading by a person
Inventor: KALKBRENNER ERNST DR ING
IPC: G01B5/207
Filed: 1982-03-06
Abstract: The essential point of the invention is the use of push rods which transmit the deformation to a measuring scale. The required number of push rods are stuck through the upholstered seat and inserted into the seat until the flat push-rod head terminates with the seat surface. The pointed end of the push rod projects on the seat underside (or rear of the rest) into a cylindrical sleeve which is constructed to enable a relatively large longitudinal displacement of the push rod in the sleeve. A spring between the push rod and sleeve is set such that the dead weight of the sleeve is just insufficient for a displacement. A marking on the push rod and a millimetre scale on the sleeve enable the position of the push rod to be read off to the nearest millimetre, and thus enable the give of the seat to be measured.

Title: Device for connecting two butt-jointed reinforcing bars by means of a sleeve
IPC: B21D39/04
Filed: 1982-09-11
Abstract: The device is used to press the sleeve onto the ends of two reinforcing bars by way of an axial relative movement between an upper and a lower machine part to form a drawing die (13) arranged on a lower machine part. The lower machine part has a baseplate which is constructed in the shape of a fork at its front and is provided with a recess for inserting the drawing die (13). The drawing die (13) consists of two parts (13', 13'') of different arc length, of which the shorter inner part (13'') is connected to the baseplate (1) and the longer outer part (13') can be inserted into the recess (12) in the baseplate (1). On the underside, the outer part (13') has a shoulder (16), by which it bears on corresponding abutment surfaces (17) at the front ends of the limbs (8 and 9) of the baseplate (1). As a result, the reaction force from the deformation of the drawing die is absorbed by force components acting in the longitudinal direction of the limbs, so that the limbs are kept substantially free from bending stresses. <IMAGE>

Patent DE-3237025-A1 (DE)
Title: Structural member and process for its production
Inventor: KIRCHNER-CARL ANGELIKA
IPC: E04C2/284
Filed: 1982-10-06
Abstract: The invention relates to a structural member which comprises a frame and a lining of the frame interior. Known structural members of this type previously had to be made and fitted together to order, which made their production more expensive and also undesirably increased the amount of work involved. There were therefore efforts to obtain a universal structural member which can be produced more simply and inexpensively than the known members. This is achieved by the fact that the lining of the frame is a shrunk plastic film enclosing the frame crossbeams, embodiments of the invention also being distinguished by the fact that the frame has transverse and longitudinal struts, and that the inside of the film is provided with a flexible filling which is under compressive prestressing.

Title: Peristaltic pump
Inventor: GULDENER HANS JAKOB
IPC: F04B43/12
Filed: 1983-07-25
Abstract: In a housing (1, 2), a plurality of tube-constricting rollers (3) are guided movably along a circular trajectory. A tube support member (7) serves to support a tube in contact with the perimeters of the rollers (3) on a section of the circular trajectory. The tube support member (7) is arranged movably in the housing (1, 2) and held by a bolt (10) which engages, by means of an eccentric section (10a), a slot in the tube support member (7). In operation, the tube support member (7) can pivot around the bolt (10) and is capable of limited movement relative to said bolt. By means of this resilience of the tube support member (7), the tube is preserved. By rotating the bolt (10) it is possible to adjust, via the eccentric section (10a), the gap between the tube support member (7) and the trajectory of the rollers (3), and to adapt said gap to the wall thickness of the tube used in a particular case. <IMAGE>

Title: Circuit arrangement for evaluating a pilot carrier in multi-channel sound operation
Inventor: MOSCHNER JOERG
IPC: H04N5/60
Filed: 1983-08-31
Abstract: In the multi-channel sound process, an evaluation of the received transmitter must be performed in the television receiver to detect and process one of the possible operating modes of mono, stereo and two-tone. A critical phase in this is the switching-over when changing channels. Although the evaluation circuits can be used to avoid clicking noises while switching over, misidentifications are often caused by switching-over, with the consequence that the associated operating mode is not correctly detected for the channel received after switching-over. The invention remedies this by automatically switching the evaluation circuit to mono identification for a selectable period of time during switching-over. In the case of an evaluation circuit which, for detecting the respective operating mode, requires the line fly-back pulse, which is fed to a reference frequency input, this can be achieved by simple means by muting the reference frequency input during switching-over. This muting automatically leads to a mono identification, so that misidentifications are avoided during the selectable period of time and no clicking noises occur.
