Patent DE-2925123-A1 (DE)
Title: Yarn-ribbon processing drum - has carrier bands to moved coiled material across drum width
Inventor: BERGELT KARL
IPC: F26B13/00
Filed: 1979-06-22
Abstract: As the yarn or ribbon material is wound round the processing drum--for immersion, washing, drying and/or cooling -- it is supported by the continuous carrier bands which are placed parallel to each other round the surface running across the width of the drum. As the carrier bands are moved, so the yarn or ribbon material is carried in a direction across the drum width. The design allows a continuous yarn/ribbon treatment process, where the untreated material is fed in at the same speed as the rate at which the treated material is passed out of the process.

Title: Flame cutting machine for continuously cast billets - where oscillating pendulum burners cut billet transversely
Inventor: HENNECKE FRANZ
IPC: B22D11/126
Filed: 1979-06-30
Abstract: The billet travels along a roller track, and may have a round, square, or rectangular cross-section; in the last case, it stands on edge on the track. Above the track is a mobile flame cutting machine travelling together with the billet, and fitted with a traverse provided with pivots for one or more burners. The spaces between the rollers forming the roller track are designed so the rollers are not exposed to the burner flames. Tbe pivot mountings for tbe burners are pref. high above the track so the jets of flame can meet at the middle of the billet. Used e.g. for cutting billets up to 800 mm wide.

Title: Animal fodder prepn. - by adding liq. preservative spray to vortex in separator between grinder and mixer
Inventor: BARTHEL WALTER
IPC: A23K30/00
Filed: 1979-07-19
Abstract: Fodder which is to be treated during the crushing operation by a preservative such as Ca propionate is passed from a grinding mechanism to a separator in the form of a vertical cylinder with a conical bottom which separates the air and directs the ground prod. to a mixer. The preservation is sprayed in metered quantities through a nozzle which is pref. directed from the separator wall radially towards the centre of the vortex inside the conical part. This ensures an excellent wetting of the entire surface of the ground particles and prevents wastage of materials.

Title: Switching signal generating system - uses pressure or underpressure on suitable layer with conductive and non-conductive parts
Inventor: STRAUB HARTWIG
IPC: H01H35/00
Filed: 1980-01-09
Abstract: The signal switching system is intended for a universal switch, e.g. for warning or tripping purposes. If the switch is fitted with a cavity, the latter can be filled with a gas or liquid, or another suitable material, which results in a precision switching point. The switching signal is produced by applying a pressure, or underpressure, on a suitable layer. The layer of non-conductive material may include a conductive layer, suitable for contacting. The switching point may be changed by the applied material change of parameters. The non-conductive layer may have a cavity filled with a gas or a liquid under defined pressure. The layer material may be porous and thus permit suitable diffusion for attaining the required switching point. If the cavity is filled with a fusible material, it may have a defined melting point for switching signal tripping.

Title: Package container for e.g. tooth-paste or shoe polish - has rotatable cap and leadscrew moving piston inward to dispense contents through metering openings
Inventor: SCHNEIDER HILMAR
IPC: B65D83/00
Filed: 1980-08-06
Abstract: The package container for materials with the viscosity of toothpaste or shoe polish has a cap which carries inside the container a hollow leadscrew. A piston is threaded to the leadscrew. A piston is threaded to the leadscrew at the open end of the cylindrical container and is urged inside the cylinder by turning the cap.

Title: Silicon carbide mouldings - made from silicon carbide grains mixed with rice husks which form sec. silicon carbide binder during baking of mouldings
IPC: C04B35/565
Filed: 1980-08-21
Abstract: The mouldings consist of SiC grains which are bonded together by SiC formed during the mfr. of the mouldings. A mixt. is made contg. SiC grains, and milled or unmilled rice husks or substances contg. similar amts. of Si and C. The mixt. is then moulded and baked in the usual way. The rice husks are pref. coked at min. 300 deg.C., esp. at min. 900 deg.C, before being added to the SiC. Up to 50 wt.% of rice husks prior to coking are pref. used in the mixt. and have a max. size of 2 mm. After coking, the husks pref. have a max. size of 0.5 mm. The uncoked or coked husks are pref. made into a suspension in a temporary moulding agent before being mixed with the SiC grains. The mouldings are pref. baked above 1290, and esp. above 1350 deg.C. Conventional SiC mouldings are made by mixing SiC and C, and then exposing the moulding to Si vapour so sec. SiC is formed and functions as the binder. This expensive process is eliminated by the invention, which only requires simple baking.

Title: Flat pressed wound foil capacitors prodn. - by pressing into flat form with greater pressure at centre than in terminal zones
Inventor: OSSNER ANTON
IPC: H01G4/32
Filed: 1980-10-13
Abstract: Flat-pressed wound foil capacitors are produced, having welded or soldered terminal components (8,9) symmetrical about the longitudinal central plane, by pressing initially cylindrically wound capacitors under heat and then fixing them. During this flat pressing process, a non-uniform pressure (10) is applied to compensate for tolerance deviations in the diameter of the initially round object and/or different internal strengths of the coil. Pref. a greater pressure is applied at the centre than in the terminal regions, resulting in the slight "dumbell-shaped" form illustrated. Pref. the capacitors have a dielectric foil of polyolefin, esp. polypropylene. The pressure may be applied by a cushion-like pad. Process results in a considerably reduced scatter of the capacitance values of the capacitors.

Title: Control arrangement for a metal rolling-mill and method of impact-loading compensation
Inventor: FAPIANO DONALD JOHN
IPC: B21B37/46
Filed: 1981-07-04
Abstract: A speed-control arrangement for a motor drive which is used for driving a working roller (14) of a metal rolling-mill, in which a metal workpiece (10) is guided through between two working rollers (12, 14) in order to form the workpiece, contains a first and a second return path, which supply signals which are proportional to the roller speed or to the motor current and linked with one another in order to ensure a basic speed control of the motor (20). Speed changes as a result of abrupt changes of the loading of the rollers (12, 14) which are caused by inconsistencies in the workpiece (10) which enters between the rollers are compensated by generating a compensation signal which is linked with the basic speed signal in order to generate a final control signal for the motor. The compensation signal is generated depending upon the force which is required, as a result of the presence of the workpiece (10) between the working rollers (12, 14), to separate the rollers. <IMAGE>

Title: Boiler for burning solid fuels
Inventor: HOEFELD GUENTER
IPC: F24B13/04
Filed: 1981-10-21
Abstract: In a boiler for burning solid fuels with a fuel supply in a hopper (2) above the grate region (1), there is a risk, as a result of the underpressure arising, that infiltrated air reaches the fuel through the hopper (2). This can lead to hopper fires. Hopper fires can be excluded by a closure member (3) which seals the hopper (2) upwardly in an airtight manner. Safe closing is guaranteed by a pneumatically operated drive element which is actuated in the event of power failure by a currentlessly opening solenoid valve in a pressure line (6). <IMAGE>

Title: Adjustable belt pulley
IPC: F16H55/56
Filed: 1981-12-02
Abstract: An adjustable belt pulley with two pulley discs which are seated on a hub, revolve about its axis, accommodate a belt between them and can be displaced axially relative to one another by an adjusting device, springs or the like, should be economical to manufacture and the forces which occur are to be kept as small as possible and distributed over areas of in each case varying size. This is achieved here by virtue of the fact that, to transmit the torque to the hub (1) at least one of the pulley discs (2, 3) has coupling members (6, 7) outside the hub surface on the side facing away from the belt (4) and these coupling members engage in axially displaceable fashion in corresponding mating coupling members (9) arranged in torsionally rigid fashion on the hub (1) and extending beyond the surface of the latter. <IMAGE>
