Patent DE-3103534-A1 (DE)
Title: Plastic battery housing
Inventor: KOEDER ROBERT
IPC: H01M6/46
Filed: 1981-02-03
Abstract: A battery housing, which is produced as an integral injection-moulded part, for accommodating galvanic elements, which can be stacked in the form of a column, especially button cells, is formed from two half shells which can be folded together and are connected to one another via a flexible film hinge. A contact spring which is guided over the outer wall of one half shell allows two columns which are arranged in parallel to be connected in series, while further contact elements connect the first and last cell in the overall fit of cells to the positive terminal and negative terminal at the ends of the battery housing. When they are folded together, the half shells are closed by means of a self-locking snap closure, in that the closure elements (14, 15, cf. Figure) engage in the closure opening (18) and lock the barbs (17). <IMAGE>

Patent DE-3122601-A1 (DE)
Title: Machine for producing and/or processing rubber and plastic compounds
Inventor: THUROW GERHARD
IPC: B29B7/58
Filed: 1981-06-06
Abstract: Compounding roll mills or internal mixers such as are used for producing rubber and plastic compounds contain rolls or rotors which are driven counter-rotating with respect to one another via intermeshing radial gearwheels and whose circumferential sections facing one another delimit a gap of variable width. According to the invention, the gap width is influenced by radial adjustment, in the same direction, of the radial gearwheels on their spindles with the centre clearance of the rotors remaining uniform. For roll mills, this leads to changes in the friction with virtually the same effect.
Patent DE-3124725-A1 (DE)
Title: Process for sterilising and homogenising and melting a cheese composition, in the production of cheese spread, without using pressure
Inventor: ZIMMERMANN FRIEDRICH
IPC: A23C19/08
Filed: 1981-06-24
Abstract: The object underlying this process is to combine the multiplicity of apparatuses which are used at present in one technological sequence and to simplify them. This object is achieved according to the invention in that the steam inlet nozzles are replaced by a new one by means of which we can simultaneously melt, sterilise and homogenise, but not under pressure. This nozzle provides the steam entering at 5.5 atmospheres above atmospheric pressure with a velocity of 660 m/s, and a temperature of approximately 140-150 DEG C directly at the outlet. By virtue of the temperature and twice the velocity of sound, a deep effect in the colloidal system is achieved, the effect of which has a destructive action across the entire microbiological spectrum, but simultaneously homogenises the cheese spread. Since this does not take place under pressure, the cheese composition has a temperature of approximately 90-95 DEG C. The nozzles can be installed in any melting equipment. They require no maintenance. No cooling water is required. No post-creaming equipment and no homogenisation units are required. This results in lower costs and at the same time saving in labour. A sterile and homogenised final product is ensured.

Title: Device for indicating filter exchange and for adjusting and maintaining constant the wall thicknesses in the extrusion of pipes, films and profiles
Inventor: BECK ERICH
IPC: B29C48/09
Filed: 1981-08-08
Abstract: Device for indicating the filter exchange and for adjusting and maintaining constant the wall thicknesses in the extrusion of pipes, films and profiles with screws fed from below. By feeding the extruder from below using an accurate metering unit, the throughput accuracy through the metering unit is determined and maintained at least until there is back pressure in the extruder intake. This back pressure is used to signal the filter exchange. The accurate knowledge of the throughput or of the charged portion makes possible the preselection of the profile wall thicknesses by a calculated preselection of the take-off rate or of the length in running metres per charged portion from the relationship: throughput = take-off rate x cross-section or    charged portion = length x cross-section.

Patent DE-3132876-A1 (DE)
Title: >>Regenerator for digital, in particular quaternary, signals<<
Inventor: ROEDER HORST DR ING
IPC: H04L25/49
Filed: 1981-08-20
Abstract: In a regenerator for digital, in particular quaternary, signals with an amplitude discriminator, a downstream time discriminator and a connected feedback network, spectral components, even of a higher order, are intended to be compensated for. A correspondingly complex higher-order feedback network would be required for this purpose. According to the invention, this higher-order feedback network is replaced by a plurality of simple parallel-connected networks. In one embodiment of a second-order network, the output signal of the non-linear arm (1) of the regenerator is connected to both a low-pass filter (2) to compensate for the first-order signal components missing from the signal following transmission and to a high-pass/low-pass (filter) series circuit (4, 3) to compensate for second-order signal components missing from the signal following transmission. The sum of the signals U1(t) + U2(t) occurring on the two sub-networks is then added at the discriminator point to the signal U(t). <IMAGE>

Title: CO2 sporting weapon
Inventor: ALTENBURGER JOERG ING GRAD
IPC: F41B11/723
Filed: 1981-08-28
Abstract: A CO2 sporting weapon (sports weapon), especially a CO2 pistol, having a CO2 cartridge (5) which can be released from the weapon, is used as a supply container and has a spring-loaded valve (70) which is opened automatically during attachment to the weapon, and having a seal (58) which, when the weapon is ready to fire, prevents CO2 emerging at the junction point of the CO2 cartridge and the weapon, is characterised in that a further valve (35) is arranged on the weapon, at the connection point for the CO2 cartridge, which further valve (35) is opened when the cartridge is attached and releases the path for the CO2 to a firing valve (10) which initiates the shot, and in that the arrangement is designed such that the seal (58) is already sealed during attachment of the CO2 cartridge (5) to the weapon if the valve (70) and the further valve (35) are still closed, and, during removal of the CO2 cartridge from the weapon, is not opened until the said valves are closed. This prevents CO2 being lost and noise being produced during replacement of the CO2 cartridge. <IMAGE>

Inventor: BROCKHAUS RUDOLF DR
IPC: C07C57/04
Filed: 1981-10-27
Abstract: To produce methacrylic acid, firstly, isobutyraldehyde is acetalized. The resultant acetal is cleaved into the isobutenyl ether and alcohol. The isobutenyl ether is oxidized with molecular oxygen or an oxygen-containing gaseous mixture in the presence of an alkaline solution at temperatures of 30 DEG -70 DEG  C. to obtain the epoxide. This epoxide is hydrolyzed to the  alpha -hydroxyisobutyraldehyde. The latter is then oxidized with concentrated or fuming nitric acid at temperatures of 20 DEG -110 DEG  C. to produce  alpha -hydroxyisobutyric acid, and methacrylic acid is obtained therefrom by splitting off water.

Title: Process for producing reinforced concrete slabs and reinforced concrete slab produced by the process
Inventor: HAEUSSLER ERNST DR ING
IPC: E04C2/04
Filed: 1981-12-30
Abstract: Process for producing reinforced concrete slabs, namely especially reinforced concrete slabs of storey height and large size, with an architectural outer layer, reinforcements of reinforcing steel, for example steel wire reinforcement, and concrete containing coarse and fine aggregates. First the outer layer and in addition the reinforcement and the concrete are introduced in one or more layers into formwork. The concrete is compacted by a vibrating step. A top layer of coarse light aggregates, supporting each other in dense packing, is arranged in the concrete. Due to the coarse top layer, the outer layer and hence the reinforced concrete slab as a whole is kept flat during setting of the concrete. In general, the coarse light aggregates will be mixed into a conventional heavy concrete which, according to the thickness of the reinforced concrete slab, is introduced in a uniform layer into the formwork, the coarse light aggregates which have been mixed in collecting in the top layer as a result of the vibrating step. <IMAGE>

Title: Information sign, particular for installation in the open
Inventor: RITSCHEL WALTER
IPC: G09F13/16
Filed: 1982-03-12
Abstract: In the case of an information sign, in particular for information in the open, for example road signs having a retroreflecting information-bearing surface, obscuring by a covering of dew or frost is prevented or at least largely reduced by backing the actual information carrier, in the form of a layer, with an essentially insulating layer. Plastic layers are particularly suitable as insulating layers. If the material of the insulating layer is sensitive to light, in particular UV radiation, the insulating layer can be covered on the front and rear side with a layer which is impermeable to UV radiation, for example a correspondingly coloured or pigmented plastic layer. If the information-bearing layer contains a metal foil, merely covering the rear side of the insulating layer with a layer which is impermeable to UV radiation suffices. For extreme conditions (for example areas susceptible to snow), the insulating layer can be additionally equipped with a heating device.

Patent DE-3213318-A1 (DE)
Title: Flow divider
Inventor: BRUNNER RUDOLF
IPC: F15B13/02
Filed: 1982-04-08
Abstract: The invention relates to a flow divider for dividing a hydraulic flow independently of load or for combining two partial flows independently of load, with a hollow control-piston arrangement arranged in an inner bore and having radial orifice openings which form with consumer-connection openings two adjustable control orifices, the mutual pressure drop of which controls the displacement movements of the control-piston arrangement. It is found in practice that the control orifice in which precisely the weaker pressure prevails actually always dominates. It is a disadvantage here that the dominating control orifice "over-compensates", as a result of which a consumer attached to it leads or lags in relation to the consumer attached to the other control orifice. According to the invention this disadvantage is removed owing to the fact that in each case an additional flow connection by-passing the control orifices is provided from the inner bore to each consumer connection. These flow connections compensate the "over-compensation effect" in a certain volumetric delivery range, as a result of which synchronous loading of the two consumers takes place, specifically during the inflow and the outflow.

Title: Absorbent material and method for its production
Inventor: PIENIAK HEINZ ALFRED
IPC: A61F13/15
Filed: 1982-04-19
Abstract: An absorbent material having a covering layer and an absorbent layer is specified, in which the covering layer consists of a nonwoven textile material and is essentially water-repellent and in which at least some fibres of the absorbent layer extend into the covering layer and are integrated in this. For the production of the absorbent material, an absorbent layer is formed by air-laying of absorbent fibres on the covering layer, a reduced pressure being generated on the side of the covering layer which faces away from the absorbent layer. Specific examples of use of the absorbent material are disposable nappies, sanitary towels and incontinence pads. The absorbent material has the advantage that a strongly water-repellent covering layer can be used, as a result of which a liquid is rapidly drawn off into the absorbent layer. <IMAGE>

Title: Wind wheel with wind wedge and double rotor as screw or savonius rotor
Inventor: BORRECK HERBERT
IPC: F03D3/02
Filed: 1982-05-12
Abstract: The upstream wind wedge in front of the rotors of the wind wheel serves to improve the air stream flowing onto the rotors and significantly extends the working range of the rotors whilst at the same time shielding the parts of the rotors turning in the wind shadow of the wind triangle. In addition the mechanical stressing of the entire wind wheel system has been reduced by the wind wedge and this contributes to the reduction in the wind noise. By means of these improvements the efficiency of the wind wheel is considerably improved.
