Title: Activated carbon mfr. from organic material - in dryer, carbonising and activation furnace with reactant gas counter flow
Inventor: BORST ADOLF H
IPC: C01B32/336
Filed: 1978-06-02
Abstract: Activated carbon is produced from organic material, esp. cellulose waste, by passing the feed through a dryer, a carbonising furnace and an activation furnace where steam is introduced. The reactant gases produced in the activation furnace are passed in counterflow to the material stream to the carbonising and drying furnaces. This requires only a simple, even mobile, plant which operates at low cost. The optimum utilisation of the heat energy reduces the necessary extraneous heat input to a minimum.

Title: Hydraulically operated access equipment - having control cable to maintain orientation of work bucket during raising or lowering of boom
Inventor: ASHWORTH DENIS HENRY
IPC: B66F11/04
Filed: 1979-04-27
Abstract: The work bucket (18) is pivoted to the free end of an articulated two part boom (14, 16), which in turn is pivoted to a frame (12).

Title: Door closer with fixed position setting - has solenoid valve stopping oil flow around piston to keep door open for given time
Inventor: METTENLEITER KARL
IPC: E05F3/22
Filed: 1979-07-07
Abstract: The door closer has a closing spring rotating a closing spindle coupled via a gear to a piston moving inside an oil-filled cylinder. A solenoid valve opens and closes an oil channel connecting opposite sides of the piston. When the valve is excited, it closes and prevents the piston moving further. A switch responds to oil pressure and is connected to the coil of the solenoid valve so that it interrupts the latter's current when a given pressure is present on the pressure side of the piston. The switch allows the current to return after a given time. The closer is especially useful with two-wing doors where one wing has to close before the other: the closer holds one wing back whilst the other closes.
Patent DE-2930288-A1 (DE)
Title: Multi-channel remote control system - employs single receiver discriminator which is switched by multiplexing to various frequencies
Inventor: TROUSSAS JOANNIS ING GRAD
IPC: G08C19/12
Filed: 1979-07-26
Abstract: The multi-channel remote control transmission system has transmission which may, for example, take the form of ultrasonic or infrared radiation suitably modulated. The receiver comprises a single frequency discriminator whose reference point is cyclically varied by a multiplexer. The variation may be achieved by connecting fixed frequencies to which one of the received frequencies will be matched at any one time. Alternatively the tuning of a filter may be cyclically adjusted. The proposed circuit employs a less number of expensive integrated circuits than the pulse code modulated method or a system employing continuous transmission on a number of frequencies. The latter requires a frequency discriminator for each channel. The proposed system employs one such discriminator. The remaining integrated circuits are of standard quantity production types.
Patent DE-2941365-A1 (DE)
Inventor: SCHOPP TRAUGOTT
IPC: E04D13/15
Filed: 1979-10-12
Abstract: In order to bridge over the joint, use is made of an expansion-joint element which can move inherently in the event of temperature changes and has a central strip (1), produced from synthetic rubber, and two sheet-metal border strips (3). Over the central strip (1) there is fitted, with the aid of a securing means, a continous sheet-metal covering (9), by means of which damage to the central strip (1) is avoided. It is to be possible for the expansion-joint element to be bent off, along with the sheet-metal covering (9), on the building site and for the sheet-metal covering (9) to be removed and refitted at any time for monitoring purposes. To this end, the securing means is formed by a sheet-metal intermediate strip (7) which is vulcanised onto the central strip (1). At individual points, the sheet-metal covering (9) is releasably connected to the sheet-metal intermediate strip (7). <IMAGE>

Title: Heat exchanger for enclosed rotating machine - has cooling tubes and heating rods using expansion for shrink-fitting onto stator
Inventor: BOEHM FRANZ ING GRAD
IPC: H02K9/18
Filed: 1979-12-21
Abstract: The heat exchanger (2) is made of aluminium or similar and fits in one piece over the laminar stator packet (1) by means of a shrinkage fit. The exchanger contains axially-parallel cooling tubes (3) and heating rods (4). The rods are near the inner surface of the exchanger and are used to heat the exchanger. The cooling tubes end in holes (5) in support rings (6,7) connected to bearing plates. A gap (9) for cooling is left between the outer casing (8) and the exchanger. External air flows through the cooling tubes. The heating rods can be connected to a current source so that the exchanger expands and can be readily fitted onto the stator.

Title: Automobile engine with cylinders selectively cut-out at low load - uses engine oil pressure to control sliding plate blocking valve stem and has electromagnets attached to plungers in switch circuit
Inventor: LEITERMANN WULFT DIPL ING
IPC: F01L13/00
Filed: 1979-12-22
Abstract: The cylinders are cut-out at low load by blocking the lifting valves operated by a cam shaft via a sliding pusher (8). This incorporates a plate (24) movable transverse to the direction of movement of the pusher (8) between two end positions. In one of these the plate (24) provides a stop face contacted by the valve stem and in the other end position it allows free movement of the valve stem. The sliding plate (24) acts as a piston moving between its two end positions in dependence on the pressure supplied to two chambers (28,31) on either side of it. These pressures are obtained in dependence on the engine oil pressure and hence the engine load. The two chambers (28,31) are each connected by an oil pressure cylinder (46) to plungers which actuate electromagnets (48,49) in circuit with a cam operated switch (54).

IPC: F24D11/02
Filed: 1979-12-28
Abstract: The heat collector for a solar heating system is connected by supply and return lines for a heat exchange medium to a circuit with a collector vessel, a pressure regulator and a compressor followed by a heat exchanger. This heat exchanger has a coil through which water is circulated to a room heater. The supply and return lines travel close together so that there is heat exchange between them. They are pref. embedded in the wall of the room, and the return line incorporates a drying unit and a thermal expansion valve. This valve is relatively near the compressor and heat exchanger but relatively far from the heat collector.
