Title: High pressure cleaning appliance - uses high pressure cold water pump feeding spray gun through coil inside boiler
Inventor: MANN WILHELM DIPL ING
IPC: B08B3/02
Filed: 1979-05-17
Abstract: The high pressure cleaning appliance is equipped with a high-pressure pump which passes cold water from a feed tank to a heating coil in a boiler. The boiler firebox is heated by an oil or gas burner and the hot water produced by the boiler is taken to a hose with a spray gun. A bypass can be opened to direct cold water directly to the spray gun. The boiler includes a burner, a firebox and a re-entrant combustion chamber while the hot water system consists of the high-pressure coil, an expansion vessel and a safety valve. A high-pressure water pump for a pressure of 60-130 bar draws cold water from a float controlled feed tank which is connected to the water mains. The hot water is delivered to a spray gun and the bypass is controlled by a 3-way valve or solenoid valve to direct cold water straight to the spray gun.

Patent DE-2920671-A1 (DE)
Title: Breathing apparatus - with clockwork triggering starter for second oxygen generating cartridge after half time
Inventor: PASTERNACK ADALBERT DIPL ING D
IPC: A62B7/08
Filed: 1979-05-22
Abstract: A breathing apparatus regenerates the respiratory air by parallel cartridges with a chemical which absorbs CO2 from the respiratory air and produces O2. When a pull rod is pulled, it actuates a trigger for the chemical or pyrotechnical starter of the first cartridge. At the same time it starts a clockwork mechanism which withdraws a catch and releases a latch. This allows a spring to drive a trigger against the starter of the second cartridge when half the useful time has elapsed. This automatically actuates the second cartridge when the first is spent. The user can, however, delay the initiation of the second cartridge by pushing in the pull rod.

Title: Storage oscilloscope with digital signal generation facility - has stored oscilloscope display scanned at control rate to generate equivalent digital signal
Inventor: JAHNEL BENNO DIPL PHYS
IPC: G11C27/02
Filed: 1979-10-10
Abstract: The memory oscilloscope system with a facility for analogue signal display storage is also combined with a facility to generate an equivalent digital version that can be separately stored in memory. When an input pulse (1) triggers a signal generator (2), an analogue signal (3) is produced that is fed to the tube (4) of an oscilloscope. The signal is held for display in a layer of the CCD elements. Independently of the display storage, a separate tube (6) is used to scan the display on a line basis. The generated digital signal (7) may be processed by a computer (8) or held in memory for recall at a later point.

Title: Nuclear reactor penetration for cables esp. through pressure boundary - has cap with welded sleeves each for one cable
Inventor: NICKEL WALTER
IPC: G21C17/116
Filed: 1980-04-23
Abstract: A penetration for conductors, esp. instrumentation and supply cables, through a wall is intended particularly for the flow (pressure) boundary plate of a nuclear reactor. The penetration comprises a pipe (1) passing through the wall, and a cap (2) mounted on the pipe and containing a number of sleeves (3), each for one conductor (4). Pref. the cap is prevented from rotation by a transverse pin passing through it and the pipe. The individual sleeves (3) are pref. constructed as lengths of pipe, more specifically of stepped dia. the larger diameter being welded to the outside of the cap (7). Used esp. for pressure boundaries in nuclear reactor plants, where an unknown number of instrumentation or other cables have to pass through the boundary and provision must be made for installation in the future. The arrangement requires only one, fairly large penetration through the wall and then provides accommodation for a number of cables through the sleeves in this penetration. The penetration is intended esp. for regions of comparatively high temperature where the penetration is subjected to high temp. over long periods and personnel access is limited.

Title: Connector for electric installation wires - has shank with spring arm bent through 90 degrees from other shank in long slot region
Inventor: SCHOLTHOLT HANS
IPC: H01R4/24
Filed: 1980-06-27
Abstract: The connector is intended for wires of different diameters, which can be clamped in two clamping jaws for contacting. These jaws are formed by a clamping slot in a flat connector, where they are formed by folding back the free ends. At least one clamping jaw forms a sprung arm, extending transversely to the respective installation wire section. This arm is formed by the folded shank of the connector by a long slit whose length gives the required resilience. The shank (4) with the sprung arm (3) is in addition angled away through at least 90 deg. from the other shank (6) of the connector (1) in the region of the long slit (5). Pref. the sprung arm shank is folded back through about 180 deg. up to the lower shoulder of the clamping slot (2). The free end of the shank with the sprung arm may be formed as plug contact.
Patent DE-3024601-A1 (DE)
Title: Piezoelectric transducer with signal actuated function - uses electric control signal to switch fluidic pressure flow from one output to another one
Inventor: KLOCKE HARALD
IPC: F15C1/04
Filed: 1980-06-28
Abstract: An electric signal actuates a control member, in order to trigger a transducer switching function in relation to the appearance or quenching of a fluidic output signal. The pressurised fluidic flow is affected in an inlet zone by a fluidic interference magnitude, produced by the electric signal, in such a manner that the pressurised flow is switched from one transducer outlet to the other. The fluidic interference magnitude is pref. generated by an electrically energisable oscillation generator (8), comprising a diaphragm (9) closing a resonator chamber (15). The diaphragm surface is connected with an oscillator crystal (10), while a turbulence amplifier (1) is used as a fluidic element. The amplifier and the oscillator may form an integral unit, the amplifier having an inlet zone (4), through which flow the pressurised fluid from a connecting union (P).

Inventor: MEYER ERICH
IPC: B31B70/00
Filed: 1980-07-03
Abstract: Draw-string bags are produced from thermoplastic films which are bonded together along at least one longitudinal edge, those edges are folded over to take the draw-string and holes are punched out at intervals according to the width of bag produced; draw-strings are fed into the folds which are then welded, lengths of string are pulled out through the punched holes, pairs of strings are welded together at two points and separated, and the film is cross-welded into a bag. The draw-strings themselves are weldable and are welded together after their lengths have been pulled out from the folds. Low cost process which requires little space and few component parts, products can be mechanically handled.

Title: Safety circuit for motor-driVen side window of vehicle - switches motor off when end microswitch and safety switch are operated
Inventor: JEDECK HELMAR ING GRAD
IPC: E05F15/47
Filed: 1980-07-26
Abstract: The safety circuit has a safety switch that is actuated when an object is caught in the window. A microswitch (12) is operated by the upper edge of the side window (3) as it travels upwards. The motor (2) driving the window is stopped for a given time when both the safety switch (11) and the microswitch have been operated. The microswitch is located between the fully-closed position of the window and the position in which an object can no longer be trapped. A timing circuit defines the time for which the motor remains off. After this time has elapsed the motor remains off if the switches have not been released. The motor direction is reversed if only the safety switch is operated. The same arrangement may be used for car doors, boots etc.

Title: Concrete pump with hydraulic drive - has regulated non-return valves to prevent concrete pressure forcing pistons back when pump stops
Inventor: GRIESBACH ROLF ING GRAD
IPC: F04B15/02
Filed: 1980-08-08
Abstract: The pump has two pumping pistons (7,8) in cylinders. Each piston is connected by a rod (5,6) with a driving piston (3,4) in a driving cylinder (1,2). A pump (10) delivers hydraulic fluid to a delivery oipe (12) and a relief pipe (13) returns it to the tank (11). A changeover valve (15) connects the delivery and return pipes with each driving cylinder in turn and changes over on each stroke so that the pistons move out of phase with each other. Non-return valves (20,21) in the connections to the driving cylinders (1,2) are held open by an automatic control (22,23) when the pump is in operation and closed when it stops.
