Patent DE-2339158-A1 (DE)
Title: Submersible centrifugal pump with increased output efficiency - pressure balance is achieved via the pressure bearing and not the rotating blade wheel
Inventor: BARTELS HENNING G DR ING
IPC: F04D15/00
Filed: 1973-08-02
Abstract: Horizontal centrifugal pump unit has a displaceable blade wheel which ensures a degree of efficiency by allying pressure balance not to the blade wheel, but to the pressure bearing. The outer diameter of the pressure bearing corresponds approximately to the suction mouth of the blade wheel. The plate of the pressure bearing is fitted displaceably axially within a cylinder, but does not rotate and is fixed firmly to the housing. The vacuum required for the pressure balance is produced from the blade wheel input side by means of the hollow shaft of the pump and motor to the other end behind the pressure bearing. The plate of the pressure bearing rotates in a cylinder, which, including its terminal hollow space, is sealed against the pump body. The pressure thus produced, in that hollow space, means that the same pressure apertains as on the suction side of the pump. Since no essential enlargement of the rotating upper surface of the pump is required for this pressure bearing unloading, the degree of efficiency of this type of pipe-line pump is considerably increased.

Title: Translation invariant reading of alphanumerical symbols - involves coherent optical correlation and scanning by moving light beam
Inventor: DOUKLIAS NIKOLAOS DIPL PHYS
IPC: G06V10/88
Filed: 1973-11-26
Abstract: The symbols are in a binary code, and are scanned sequentially and in lines, and converted into electric signals in the form of a bit train. These signals are modulated on a carrier frequency fed into an ultrasonic light modulator and are correlated with masks behind the modulator. The correlation signals are then measured in a cylinder transformation lens focal plane by a photocell; the masks are transmission grids with analogue binary phase coding for each type of symbols. Additional detail filters with binary phase coding are used, detecting significant differences between symbols difficult to distinguish from each other; the masks are interdigital structures, and the ultrasonic light modulator is replaced by corresponding electroacoustical surface waveguide.

Patent DE-2366038-A1 (DE)
Title: Small pressure vessel - consits of tube and shell shaped convex base
IPC: B21C37/15
Filed: 1973-07-24
Abstract: This method is used for making components of spherical ended cylindrical pressurised fluid containing vessels. The pressure vessel is made by joining together the open end of two cylindrical open ended vessels which have spherical closed bottoms by electron beam welding, hence the pressure vessel has only one welded joint. A forged dished blank is turned to form a thin walled base. The upper part of the blank is turned to have a thick walled cylindrical section. The machined configuration is subjected to a metal spinning process to obtain a spherical end to a cylindrical body. The spinning is carried out by exerting pressure by a roller against the machine blank. This method eliminates extensive turning of components from solid or finished forging.

Title: Dish washer with safety cut-out for heating elements - includes suction pipe which admits air when water level drops thus reducing pressure
Inventor: WEIHING KURT
IPC: A47L15/42
Filed: 1974-03-14
Abstract: The dish washer includes a water circulating system and electrical heating systems and to ensure that the latter do not overheat or function when there is insufficient water suction pipe is inserted parallel to the connectng pipe between the liquid collecting basin and the circulating system. The inlet opening of this suction pipe is mounted in the collecting basin above the panel determined by the top heating element. Thus as the liquid level in the pump falls air is fed in before the water level drops below that of the heating element so that the air causes the pressure in the circulating system to drop rapidly which means that the heating circuit is broken by the pressure switch, which is the normal safety measure to prevent overheating.

Title: Percussive rock drill striker - free travelling linear motor rotor as striker, stator as vibration damper
Inventor: VONNEMANN GERHARD DIPL ING
IPC: E21B1/22
Filed: 1974-05-13
Abstract: Percussive rock drill striker mechanism consists of an electric motor to provide the striking force on the portable tool. To cut down on components and servicing, the impact mass is provided by the free travelling rotor component (1) of an electric linear motor, or else the rotor drives an impact member through a coupling. By connecting the stator (2) of the drive to the housing by a system of springs (9), the stator can be used to actively damp down the vibrations which result from the impact actions. The recoil should be absorbed by reversing the sense of the rotor movement with the aid of springs (6). Rotor and/or stator can be made to pump their own cooling air by the provision of suitable valves (e.g. 10) and supply this air through the tool bore to cool this and the hole face.

Title: Pressure monitor for dual circuit braking cylinder - which has piston balanced by two pressures to close off outlet to lower pressure
Inventor: BELART JUAN
IPC: B60T11/20
Filed: 1974-05-29
Abstract: The twin circuit braking system is provided with a master brake cylinder in which tw pistons are joined by a rigid rod. The output ducts from the two parts of the cylinder are joined by a special transverse duct in which a floating piston is held in the mid position between two springs. The relative pressures of the springs are similar so that the floating piston ensures equal pressures in the two outputs, irrespective of volume differences in the systems. If any one circuit fails in pressure then the floating piston is sufficiently displaced to cut off that duct and maintain the pressures in the two piston chambers. The braking characteristics then remain the same.
