Patent DE-3113387-A1 (DE)
Inventor: WIEDERMANN ROLF DR
IPC: C08G18/32
Filed: 1981-04-02
Abstract: Light foams containing urea and urethane groups and having a density of at most 0.025 g/cc are produced by reacting a polyisocyanate with at least one equivalent of water in which mono- and/or oligo-saccharides have been dissolved (as blowing agent) in the presence of organic compounds containing at least two hydroxyl groups and having an OH number of from 30 to 250, a catalyst and a flameproofing agent. Chain extending agents having a molecular weight of from 32 to 62 and other known auxiliaries and additives may also be used. The foams thus produced are nonflammable and are particularly useful in insulation applications.
Patent DE-3123333-A1 (DE)
Title: Switch in which a sliding contact is made
Inventor: HORN HANS-JOACHIM
IPC: H01H1/44
Filed: 1981-06-12
Abstract: There are switches in which sliding contact is made between a fixed-position contact element (2) and a moving contact element (7) which is seated at one end of a switching arm (4) and around whose other end the moving contact element can be pivoted from a null position over the fixed-position contact element and back again. In this case, a switch is desired which is more suitable for electronic circuits in that a contact resistance in the supply lead to the switching arm is avoided and the number of individual parts is reduced. This is achieved if the other end of the switching arm (4) is supported (5) rigidly such that it cannot move, the connection of the power supply lead (6) to the switching arm has no contact resistance, and the switching arm (4) is constructed as a spring which also forms the springing (which produces the contact pressure), and an actuating element (8) engages on the switching arm spring (4) at a distance from the support (mounting) (5), the switching arm spring being stressed not only in the direction of the contact pressure but also transversely thereto, subject to bending, and being constructed as a wire. Since the switching arm (4) support is rigid and does not move, it is constructed as a spring, the contact pressure being produced by this spring. This is achieved by bending of the switching arm spring in two mutually perpendicular directions, and corresponding construction of the switching arm spring with a method of construction which uses few components. <IMAGE>

Title: Process for producing acid curd cheese in relatively large pieces
Inventor: MASCHER LUDWIG
IPC: A23C19/068
Filed: 1981-06-26
Abstract: In a process for producing acid curd cheese in relatively large pieces (hitherto up to 150 g), acid curd is comminuted, receives an addition of ripening salts, is moulded and stored for ripening. The limited piece size (piece weight) demands a considerable expenditure in the production process, in that each individual piece must be handled and treated. For the production of relatively large pieces, the acid curd, after ripening salts are added, is ripened by storage in a non-moulded state, the raw material generated in this manner is comminuted a second time and intimately mixed together, and only after this does the moulding into the relatively large piece size take place. An acid curd cheese - even in a cake shape - can thus be produced which is evenly ripened through over the cross-section and from which relatively small portions can be separated off.
Patent DE-3126213-A1 (DE)
Title: Shut-off fitting for gas lines in particular
Inventor: MUELLERS JOSEF
IPC: F16K31/68
Filed: 1981-07-03
Abstract: The invention relates to a shut-off fitting for gas lines in particular, consisting of a fitting housing (1) with gas inlet pipe piece (2) and gas outlet pipe piece (3) and with a valve seat (4) between gas inlet pipe piece (2) and gas outlet pipe piece (3) as well as of a valve-closing body (5) which is guided towards the valve seat (4), is held in the open position by means of a restoring spring (6) and can be transferred into the closed position against spring action by means of an actuating device (7) and is movable in the closing direction independently of the actuating device (7). In order to bring about automatic shutting off of the respective gas line in the case of the effect of fire as a consequence of the temperature increase resulting therefrom, an expanding-material cartridge (12) is arranged between the valve-closing body (5) and the actuating device (7). This expanding-material cartridge (12) has an axially movable expanding bolt (13) which works coaxially on the valve-closing body (5) and which is actuated by the expanding material (18) in the expanding-material cartridge (12), which expands at a predetermined temperature. <IMAGE>
Patent DE-3126853-A1 (DE)
Title: Compaction drawer for a device for cutting plant materials, in particular tobacco
Inventor: SAGEMUELLER FRANZ ING GRAD
IPC: A24B7/14
Filed: 1981-07-08
Abstract: The invention relates to a compaction drawer for a device for cutting plant materials, in particular tobacco, with conveyor elements which lie opposite one another and which enclose between them a passage which narrows in a funnel formation in the direction in which the cutting material is conveyed, with a charging hopper arranged in the intake area of the conveyor elements and with a mouthpiece arranged in the outlet area of the conveyor elements, it being possible for cutting elements to be guided past the mouthpiece. In order to minimise different bulk densities, which result in an irregular compaction of the cutting material emerging from the mouthpiece, it is proposed, in a compaction drawer according to the invention, to arrange between the outlet side of the charging hopper and the intake area of their conveyor elements a pre-compaction drawer which likewise has two conveyor elements situated opposite one another. The drive mechanism of the conveyor elements of the pre-compaction drawer is coupled to an automatic device which compensates for different bulk densities by increasing or decreasing the delivery rate of the conveyor elements.

Patent DE-3129589-A1 (DE)
Title: Reinforcement element for a permanent soil anchor
IPC: E21D20/00
Filed: 1981-07-28
Abstract: The reinforcement element consists of a steel bar (1) with hot-rolled, helical ribs (2) which are arranged on two opposite sides of the bar and form a partial thread. Starting at an at least essentially circular core cross-section (3), the steel bar (1) has waist-shaped reduced sections (5) between the ends of the ribs (2). Injection and/or vent lines (6) are laid in the areas defined by these reduced sections (5) and the envelope line (7) of the core cross-section (3). The injection and/or vent lines (6) are thus protected to the greatest extent from mechanical damage when the steel bar is inserted into a borehole and they do not impede the screwing-on of a connecting or anchoring body. <IMAGE>

Patent DE-3132011-A1 (DE)
Title: Arrangement for simultaneous transmission of data via a plurality of common-wave transmitters and for equalising amplitude and phase distortions affecting the data on modulation feeders
Inventor: BITZER EBERHARD DR ING
IPC: H04B3/14
Filed: 1981-08-13
Abstract: Amplitude and phase distortions and also transit time differences occur on the modulation feeders in common-wave radio networks. Equaliser networks are described with a transverse filter structure for automatic adaptation to the respective modulation feeder. The filter coefficients are set with the aid of a digital test signal which is transmitted by the central station. The distorted test signal on the modulation feeder is compared for this purpose in the common-wave transmitters with an undistorted test signal which is stored there. The start of the adaptation process determines the overall system transit time. For simultaneous transmission of all common-wave transmitters, a pulse string, which in each case determines the start of the transmission of the digital test signal and the start of the adaptation process, can be derived, e.g. from the reception of a time signal transmitter.

Title: Method of centrally fastening an annular body on a shaft
Inventor: PFITZNER JUERGEN
IPC: F16B11/00
Filed: 1981-09-24
Abstract: The invention relates to a method of centrally fastening an annular body on a shaft, in particular an annular permanent magnet on a motor shaft, in which the annular body and the shaft are brought into a central position with respect to each other by means of a holding device and, after that, the gap between shaft and annular body, or an intermediate body connected to the shaft, is filled by a slowly setting adhesive. According to the invention, the slowly setting adhesive is applied at first zones of the gap, evenly distributed around the circumference, and a quickly setting adhesive is applied at second zones of the gap. After setting of the quickly setting adhesive, the holding device is removed, meaning that the setting of the slowly setting adhesive takes place outside the holding device. <IMAGE>

Title: Dowel with a seating force indicator
Inventor: LIEBIG HEINRICH
IPC: F16B13/00
Filed: 1981-10-26
Abstract: A force-fitting and positively locking dowel (14; 40; 86), which can be inserted in a drilled hole (18; 84) in bedrock and has a washer (38; 52; 88) which indicates the seating force. The washer, which is essentially domed in the shape of a spherical section and is arranged under a screw head (50) or a nut (34) on the outer end of a threaded bolt (30; 48; 80) engaging in the anchoring part of the dowel is dimensioned in terms of its deformation resistance such that, when the predetermined magnitude of the seating force of the dowel (14; 40; 86) is reached, it just deforms into a flat-surfaced disc. A section (90) is cut away at one point from the edge region of the washer (38; 52; 88), which otherwise has a circular boundary. A small quantity of a plastically deformable compound (94) can be applied to the side of the washer which is domed in a concave manner, which compound emerges in the region of the cut-away edge section (90) on reaching the flat-surfaced shape of the disc. <IMAGE>

Patent DE-3200038-A1 (DE)
Title: Microscope having a freely preselectable focal range
Inventor: DIETRICH KLAUS DR
IPC: G02B21/00
Filed: 1982-01-04
Abstract: The invention "microscope having a freely preselectable focal range" describes the following method (cf. Fig. 1): An object P is projected, e.g. translucently with the aid of the light source (LQ) and the condenser (K) and the lens (MO) onto an incoherent/coherent image modulator (BM) (e.g. a liquid crystal light valve by Hughes USA), and read out using coherent light (PCL) via the beam splitter (ST). This image is subjected to Fourier transformation by the lens (F1), high pass filtered in a narrow band fashion in the Fourier plane, and transformed back into the image plane (BE) by the lens (F2). By moving the object (P) in the direction of the optical axis, respectively varying focal ranges are sharply projected onto the image modulator, and appear in the image plane (BE) after the second Fourier transformation. The details projected unsharply on the image modulator are filtered out in the Fourier plane, so that when the object moves rapidly in the plane (BE) only the contours of all the details appear sharply over the focal range of the amplitude of movement. <IMAGE>

Title: Fixed window for thin-walled supporting structures
Inventor: KROLL HERBERT ING GRAD
IPC: B60J10/30
Filed: 1982-03-20
Abstract: The window can be used, for example, in vehicle building. Here, the body consisting of sheet metal merges in the region of the window aperture into a holding flange which is directed towards the inside of the supporting structure which forms a window reveal narrowing conically inwards. The sealing frame surrounding the window pane and consisting of elastically flexible material, preferably rubber, is matched, in the region of its groove receiving the holding flange, to the inclination of the holding flange and can be pushed from outside into the window reveal, specifically until it bears sealingly against this and the leg wall of said groove located on the push-in side and shifting backwards towards the frame interior springs back into its original position, when the free flange end is reached, and engages behind the holding flange, with the result that the intended interlock between the sealing frame equipped with the window frame and the supporting structure is brought about.
