Patent DE-2802787-A1 (DE)
Inventor: VRIES HANS DE
IPC: G08C17/02
Filed: 1978-01-23
Abstract: Remote control signals which are transmitted non-line-conducted by means of radio-frequency waves are used for switching load objects on and off in a power system. For this purpose, radio waves of existing transmitters, for example broadcast transmitters operating in the medium-wave band (520-1560 kHz) can be used. The transmitter operating in amplitude modulation is modulated, also in amplitude modulation, with the remote control commands in a frequency range which is below the ordinary modulation band (10 to 30 Hz with an audio-frequency range from 50 to 10,000 Hz). For this extraordinary modulation, a reduced modulation percentage of 5% is provided so that no special measures need to be provided at the transmitter end. The receiver (1) for these remote control commands is designed in such a manner that it is capable of separating the weakly modulated pulses from the ordinary modulation so that the latter cannot trigger any faulty switching. For this reason, a low-frequency filter (12) is provided as essential component of the receiver in order to recover the coded remote control commands. The output of the filter (12) is conducted via a rectifier (15) to a level comparator (18) which only passes pulse sequences which reach a modulation percentage of approximately 5%. The switching member (2) for switching a load object (3) on or off is controlled via a following decoder (21). <IMAGE>

Title: Water or steam cooled slide tube for moving hearth furnaces - with ceramic shell segments fastened interchangeably to the backing
Inventor: MITTEREGGER HEINZ ING
IPC: F27D3/02
Filed: 1978-02-07
Abstract: Water or steam cooled slide-tube for impact or moving hearth furnaces is claimed to which a heat insulating cladding of prepared ceramic shell segments is anchored, flexibly and interchangeably in the region of the joint between adjacent shell segments is anchored, flexibly and interchangeably in the region of the joint between adjacent shell segments. Specifically, the anchors are fillets welded on either side of the slide bar on the two upper quadrants of the tube and parallel to its axis. The shell segments are half shells which on their upper axial edges, which have on their upper faces which contact the slide bar have a hydraulically binding cast material filling a joint, which in the attachment region of the anchor grooves are arranged on all sides and so that a bandage of Al2O3 or SiO2 fibre fleece can be wound immediately onto the slide tube. The design avoids the prior art need for U- and T-shaped slits and the need for subdividing the segments into three to allow stress free flexibility in the radial direction at the operating temp of the furnace.
Patent DE-2808313-A1 (DE)
Title: Centrally-controlled telephone PBX - keeps operator set connected to connection side until called station is free
Inventor: SEHR WERNER ING GRAD
IPC: H04Q3/62
Filed: 1978-02-27
Abstract: The telephone private branch exchange is designed to simplify the allocation of incoming calls at peak hours. The operator's set remains connected to its connection side whilst the dialling code is being entered and until the ringing/engaged tone is received from the wanted number. Only when the called number is not engaged does a through connection occur immediately. This allows the operator to switch a call through immediately/or to execute other switching operations depending on whether the wanted number is free or engaged.

Title: Tractor driven conical helix for splitting wood - has mitre gear and suspension on tractor hoist providing longitudinal position adjustment
Inventor: HAMMERSCHMIDT MARTIN
IPC: B27L7/00
Filed: 1978-04-03
Abstract: The spiral cone acts as a rotary wedge for the wood-splitter, with a geared drive from a tractor trunnion shaft. The transmission gear comprises a mitre gear (8) with downward-protruding secondary drive trunnions (10, 10a) for the spiral cone (13, 13a). For attachment to the tractor there is a three-point suspension unit, attachable to a hoisting unit (1) on the tractor so that vertical adjustment of this effects vertical parallel movement of the gear. This obviates the need to drive the tractor backwards and forwards, and provides an abutment to prevent the wood from being turned with the cone.

Title: Refrigerator or heat pump control system - taps refrigerant fluid at compressor outlet adjusting it to mean temp.
Inventor: KARLSSON KURT EVALD
IPC: F25B49/02
Filed: 1978-05-22
Abstract: The circulating heat exchange medium in the cooling, freezing or heat pump system has a control arrangement. The arrangement ensures efficient operating conditions under conditions changing over a wide range and on changeover between different modes of operation. At the outlet end of the compressor (7) a part of the heat exchanger fluid is tapped away from the circulation. This part of fluid is diverted to the low pressure end of the compressor so that this fluid will be at a mean temp. depending on the temp. at outlet and low pressure ends. The fluid is expanded and the ratio of the liquid and gas is controlled in the expansion vessel in relation to this mean temperature. The liquid is introduced or drawn from the circulation depending on this mean temp.

Patent DE-2847301-A1 (DE)
Title: Connecting printed circuit subjected to centrifugal forces - using flexible jumper between circuit board and electrical machine connections
Inventor: HOLWECK PETER DIPL ING
IPC: H05K7/02
Filed: 1978-10-28
Abstract: The connection method is applicable to circuit board assemblies mounted on the rotor of an electrical machine. Such boards may form part of a control system. The construction relieves the circuit board connection of centrifugal stress. An insulated base (1) with conductor strips (2) is mounted on the machine rotor. Machine to base connections are made at holes in the strip (2), e.g. by bolting. The base to circuit board (6) connection (4) is a flexible wire soldered to the base terminal (3) and circuit board terminal (5). The card is contained in a potted housing (7) supported by bolts (8). The centrifugal forces on the circuit card connector are thus minimal as no part of the machine connector interacts with the board.

Title: Analogue signal synthesis using digital process - retaining signal components in digital store and converting to analogue form for combination
Inventor: BEIS UWE DIPL ING
IPC: G06J1/00
Filed: 1978-12-15
Abstract: A complex signal generator uses the combination of data signals held in several different read-write memories. Address stages are used to access the contents of a number of read write digital memory stages. The address cycle is controlled by a separate cycle control unit that is directed by a programme held in a memory. The outputs of the memories holding signal values are converted to analogue form and are added together to generate the complex analogue signal waveform. A range of complex signal waveforms may be generated and the time base varied by loading the memories with different parameters.

Title: Versatile wood chipping machine - has scanner in short timber chamber checking discharge of excess length wood
Inventor: SYBERTZ FERDINAND
IPC: B27L11/02
Filed: 1979-03-19
Abstract: The wood feed device has a chamber collecting short timber. There is a second independent feed device operating as a stationary long-timber channel parallel to this chamber. There are devices for holding timber down near the end walling of the short-timber chamber, while the opposite end has a scanning device emitting a control signal if the timber length is exceeded. This limits discharge mechanism thrust, and causes the holding devices to be lowered onto the partially forwarded short timber. This system enables either long or short timber to be worked after a very brief changeover interval.
