Title: Induction and pressure continuous piston pump for manual operation
Inventor: DULGER VIKTOR
IPC: F04B9/14
Filed: 1981-07-28
Abstract: In the case of an induction-pressure continuous piston pump for manual operation two shut-off valves (9, 10) for an end-face induction or pressure connection (19, 119) are arranged, one on one end of a cylinder (1) and the other on the other end of a piston (4) having an axial duct (5). Each shut-off valve has a valve seat (27, 127) connected to its valve housing (13, 113) and a sealing part (23, 123) interacting with this. It can be operated by handles (11, 12) displaceable relative to the cylinder or piston. The end-face induction or pressure connection (19, 119) is firmly connected to the cylinder (1) or piston (4) by way of the respective valve housing (13, 113). A carrier (22, 122) which passes through radial holes (20, 21, 121, 120) in the valve housing forming a seal connects the respective sealing part (23, 123) to the associated handle (11, 12) carried on the valve housing (13, 113). <IMAGE>

Title: Process for producing tape material from flexible plastic with porous-structured surface and covering for appliance handles
Inventor: FLETCHER HERBERT EDSON
IPC: B29C44/00
Filed: 1981-07-30
Abstract: A process is described for producing tape material from flexible plastic with a porous-structured surface and in particular the production of a polyurethane handle material (90) for appliances to be guided by hand. The material is a polyurethane tape material (10) with an adhesive lower layer. The polyurethane tape material is provided with a multiplicity of small surface pores (70, 80). The pores are formed by precipitating salt in distributed form on the surface of the still-soft starting material. The tape material is then cured and abraded, with emery if appropriate, on one surface to expose and remove some salt grains. A multiplicity of small pores (70) are exposed after removal of the salt grains. The pores (70) act as suction cups and increase the grip of the surface of the handle material (90). <IMAGE>

Title: Method for artificially generating bearing signals for simulating arbitrary angles of incidence and phase angles
Inventor: WOLF FRANZ DIPL ING
IPC: G01S3/02
Filed: 1981-08-13
Abstract: According to the invention, angle transmitters and phase shifters can be used for purposes of simulation of bearing signals within a wide frequency range due to the fact that the angle transmitter and phase shifter are only operated at a fixed frequency and the dependence of frequency on errors of these systems can not have any effect. The signals supplied by the angle transmitter and by the phase shifter are only subsequently converted to the output frequency desired for the bearing signal simulation by mixing them with the output voltage of a variable-frequency alternating-voltage source.

Title: Process and equipment for electrostatically separating a mixture containing minerals
Inventor: KLEFFMANN GERD
IPC: B03C7/12
Filed: 1981-12-31
Abstract: A process and equipment for electrostatically separating a mixture containing minerals, in particular a mixture of coal and rock, is proposed. In this case, the mixture is charged by means of corona discharge electrodes (20) and passed through a transversely directed electrostatic field between deflection electrodes within a housing (12). Corresponding to the particular charge and mass of the mixture particles, they deposit sooner or later on the plate-shaped deflection electrodes (18). Collecting funnels (22a to 22c) located one behind the other underneath the deflection electrodes (18) therefore intercept part fractions of the mixture of different composition. The equipment (10) is particularly suitable for the utilisation of rock material still containing coal, which is obtained in conventional dressing of coal in jigging machines or heavy-medium separators. This rock material is ground and passed through the equipment (10) by means of an appropriate air stream. The coal particles thereby deposit first on the deflection electrodes (18) and can be intercepted by the rear collecting funnels (22a and 22c). <IMAGE>

Title: Device for removing scales from fish
Inventor: WRUCK SIEGBERT
IPC: A22C25/02
Filed: 1982-02-06
Abstract: The invention relates to fish-processing technology, in particular the descaling of freshwater fish which are difficult to descale. The aim of the invention is to make it possible to use these fish types for immediate consumption as fresh fish. In this connection, the object is to descale the side surfaces and the dorsal parts. According to the invention, in a processing machine with conveying means engaging on the side surfaces of the fish, the conveying means are, for rectilinear horizontal transport, formed by a number of transport belts rotating in horizontal planes above one another on both sides of the transport path of the fish. In the individual planes, in each case two or more transport belts are arranged one behind another in the direction of movement leaving intermediate spaces and, in the intermediate spaces and above between the upper transport belts, descaling tools are arranged which rotate in the same direction as the transport belts and with 5 to 10 times the peripheral speed. The invention can be used in fish-processing technology.

Title: Method and device for the fast addition of binary coded information
Inventor: SCHMITT WOLFGANG ING GRAD
IPC: G06F7/509
Filed: 1982-04-30
Abstract: The problem of cyclically adding together sums having any number of bits per word occurs for the buffer storage of the binary coded information, particularly in the case of ultrasonic sector image display. The summation should be as fast as possible in this connection and the control outlay should be kept low in the associated device. According to the invention, the number of bits per word of the sums to be added is taken into consideration in a once-only lead computing time and otherwise the cyclically occurring values are added together independently of the number of bits per word of the summand. In the associated device, in each case several digital adders (1 to 3) are connected in parallel for in each case a predetermined quantity of bits (word length) and are in each case connected to a flip flop (4, 5) for buffer storage of the carry, the output line of each adder (1 to 3) exhibiting at least one register (12, 22, 32) into which an initial value of the summation can be input and fed back to the summation input of the adders (1 to 3). <IMAGE>

Title: Methods and devices for measuring the biologically active sludge content in aqueous solutions, e.g. activated sludge
Inventor: SIEPMANN FRIEDRICH WILHELM DIP
IPC: C12M1/34
Filed: 1982-06-11
Abstract: A part-stream of the activated sludge to be investigated in sewage treatment plants is removed, aerated with oxygen and continuously passed through a reaction tank, and the oxygen content before entry into the reaction tank and its residual oxygen content after leaving the tank are measured. The part-stream is diluted so that the measured difference in the oxygen content remains essentially constant. The degree of dilution then serves to indicate the biologically active sludge content. In a second variant of the method, the dilution ratio is altered stepwise when the measured oxygen difference is above or below a limiting value. With a regionally constant dilution, the measured difference in the oxygen content then serves to indicate the biologically active sludge content.

Title: Feed device on injection-moulding machines
IPC: B29C48/03
Filed: 1982-10-09
Abstract: The feed device comprises a piston-cylinder unit, into which the material to be processed, in particular polyester compositions, is introduced through a filling opening in the cylinder and fed to the plasticising cylinder of the injection-moulding machine. Above the filling opening there is an automatic loading device, which is formed by an endless, driven conveyor chain. Pivotably connected to the conveyor chain are a plurality of receiving dishes, which are filled with moulding composition and, for emptying into the cylinder, can swivel through about 180 DEG  about a horizontal axis, lying transversely to the conveying direction, in the region of the filling opening. The swivelling of the receiving dishes takes place forcibly and is controlled by the advancement of the conveyor chain. Due to the automatic filling of the feed device with raw material, time is saved and the moulding composition is to a great extent kept from coming into contact with the operating personnel and parts of the machine.
Patent DE-3239799-A1 (DE)
Title: Knife folding device
Inventor: FISCHER HERMANN DIPL ING
IPC: B65H45/18
Filed: 1982-10-27
Abstract: Tilted rotating brush cylinders are used in a knife folding device in the alignment of folded items when the second longitudinal fold is made. If a folded item is placed at an angle, so that only one side of the front edge abuts against the stops used to arrest it, the two tilted rolls push against the rear edge of the folded item. The pressure exerted in this way straightens the folded item placed at an angle, in such a way that the full width of the front edge abuts against the stops. When alignment has been completed, the knife moves in the way already known from the prior art to produce the second longitudinal fold, i.e. it moves between the pair of folding rolls to produce a second longitudinal fold parallel to the first one.
