Patent DE-2947214-A1 (DE)
Title: Motion picture automatic mixing console - has control signal recorded on main recorder tape track to initiate sound-effect admixing via mixer-amplifier stages
Inventor: GIGGE REINHARD
IPC: H04H60/04
Filed: 1979-11-23
Abstract: A sound, moving picture film, records a series or admixed sound effects onto tape. A console handles the mixing of the add-on sound effects in the desired decibel proportions. A separate sound track is provided on the main recorder tape on which a control signal is recorded. The latter replaces the manual console as it contains all the control elements for mixing the desired add-on sound effects synchronous with the main sound and film progression. If a spare track is not available the control signals may be superimposed on an active track, for example at a 25Hz basic frequency which may subsequently be filtered in a filter gate. The control action on the mixer amplifiers is proportional to the amplitude, phase or frequency modulation of the control signal and may comprise several control functions for producing various sound add-on effects simultaneously.

Patent DE-3038909-A1 (DE)
Title: Projections for resistance welding - produced without deforming outside workpiece surfaces
Inventor: TESCH BERNHARD
IPC: B23K11/14
Filed: 1980-10-15
Abstract: A method of joining metal parts by electric resistance welding, resembling the projection welding system, produces in at least one of the metal parts a line of projections without deforming the surface which will be the outside surface after completion of the weld. The projections are produced by applying either a pressure or a file cut which has a concentric action and raises the centre to a boss, leaving a groove around. This leaves the outer surfaces entirely unmarked and absorbs the molten projections in the groove, thus effecting a well-sealed joint.

Title: Method for the gas-tight sealing of ceramic flasks for storing radioactive materials, and flasks sealed according to this method
Inventor: BIENEK HEINZ ING GRAD
IPC: G21F5/12
Filed: 1981-02-27
Abstract: In a method for the gas-tight sealing of flasks for storing radioactive materials, the flask (18) is sealed by a cover (22), the flask and cover consisting at least in the joint region of a ceramic material, and thereafter the gap between the flask and cover is sealed. In order to be able to work at joining temperatures which are not damaging to the packed radioactive materials or, as the case may be, the flasks, and at atmospheric pressure, a joining glass (21, 24) is inserted into the gap between the flask and cover and heated to at least the melting temperature. The coefficient of thermal expansion of said glass is matched to that of the materials for the cover and flask in such a way that in the event of a change in temperature no impermissible thermal strains occur. The shapes of the cover and of the flask are matched to the method. <IMAGE>

Title: Process for the covalent immobilisation of biological detoxification systems on artificial surfaces
Inventor: KNAUP GERHARD DIPL BIOL DR
IPC: A61M1/36
Filed: 1981-03-11
Abstract: The invention relates to a process for the immobilisation of biological detoxification systems on surfaces that are used for the detoxification of blood and blood constituents. The three following steps are characteristic:   a) the surface is initially loaded with a layer of human serum albumin, preferably by adsorption, b) this layer of human serum albumin is then activated and crosslinked with bifunctional reagents, and finally c) the detoxification systems are covalently attached to the sites activated in this way. Biological detoxification systems for the purpose of the invention are enzymes or a combination of various cooperating enzymes, e.g. a combination of the three enzymes urease (E.C 3.5.15), alanine dehydrogenase (E.C 1.4.11) and glucose dehydrogenase (E.C 1.1.1.47) or a cell organelle. The biological detoxification system can be a multienzyme system enclosed by a natural and/or artifical membrane or be a live body cell and/or bacterial cell.

Title: Method for erecting hollow-arch supporting frameworks, especially arched bridges
Inventor: AIGNER FRANZ DIPL ING
IPC: E01D21/00
Filed: 1981-03-20
Abstract: Method for erecting hollow-arch supporting frameworks, especially arched bridges, by the use of falsework formed from a plurality of trusses which are arranged next to one another and which consist of booms arranged one above the other, spaced from one another by diagonal struts and connected to one another by tie rods. The falsework is constructed with a shuttering for the bottom plate of the hollow-arch supporting framework, whereupon parts of the bottom plate of the hollow-arch supporting framework, vertical webs and the cover plates of the hollow-arch supporting framework are produced. Sections of the bottom plate which are located above the trusses of the falsework are produced first, and these are connected in a shear-resistant manner to the uppermost boom of the respective truss located underneath. <IMAGE>
Patent DE-3124326-A1 (DE)
Title: Servo-control device for controlling reduce pressure in an reduce pressure-line system, in particular for milking machines
Inventor: HAMMERSTEIN ALBERT DIPL ING
IPC: G05D16/10
Filed: 1981-06-20
Abstract: The subject of the present invention is a servo-controlled control valve which keeps the reduce pressure, which is required for milking (or for other purposes), constant within very narrow limits and independently of the air requirement of the loads. The control valve consists essentially of a reduce pressure chamber (10) with an actuation spring (15), a control housing (24) with a control piston (1), a servo chamber (7) with diaphragm (11) and a working valve (12) with spring (14) in accordance with the attached drawing. The most important aspect of this invention is that a stable intersection point between the dynamic force-path characteristic of the pneumatic and mechanical forces (spring 14) acting downwards on the working piston (12) and the, also dynamic, force-path characteristic of the pneumatic forces acting upwards on the diaphragms (11) is obtained. This is achieved by means of a suitable selection of the spring constants of the springs (14) and (15) by means of a diabolo-shaped turned groove in the control piston (1) and by means of the damping piston (17) which terminates the damping chamber (18) with a small degree of running play. This running play ensures that, on average, atmospheric pressure prevails in the damping chamber (18), which is absolutely necessary to control a reduce pressure which is constant within very narrow limits. The working valve (12) can be constructed as a conical valve or as a slide valve. <IMAGE>

Abstract: The connecting terminal, which accommodates wires in the form of braids, has a clamping body with an orifice. A wire protection device is inserted into the orifice. This wire protection device is in the form of a strip and has a V-shaped bend in its centre region. In this case, the wire protection device has a tapered strip width in the region of the tip of the V-shaped bend, the tip engaging in a perforation in the clamping body. In the case of the method for producing a connecting terminal having a wire protection device which is arranged in an orifice in a clamping body, is in the form of a strip and has a V-shaped bend in the centre, the two limbs of the bend are moved with respect to one another until the tip of the bend comes to rest in a perforation in the clamping body.
