Patent DE-2915003-A1 (DE)
Title: Swarf remover taking cuttings from metal disc - by coiling swarf under constant tension inside suction chamber after passing between rollers with slip coupling
Inventor: LUETZKENDORF GUENTER DIPL ING
IPC: G11B3/00
Filed: 1979-04-12
Abstract: The swarf remover, for producing records or signal-recording discs, has a tube (4) connected at one end to a suction chamber (8) and lying with its other end near the cutting tool (1). The chamber is connected to a pump (7). Swarf (3) cut from the disc is sucked into the tube and wound up inside the chamber. The swarf passes along the tube and between two roller (6) inside the chamber. The rollers are connected via a slip coupling to a drive. The rollers are held together sandwiching the swarf between them by a spring (9). The Rollers are not driven at constant speed since the diameter of the groove being cut is always decreasing. The slip coupling ensures that the tension in the swarf remains constant despite this change in diameter.

Title: Expansion chamber for oil-filled cable - uses metal diaphragm between oil and gas which can stretch in two selected directions
Inventor: GOEHLICH LOTHAR ING GRAD
IPC: H02G15/26
Filed: 1979-07-27
Abstract: Expansion chambers are connected at intervals along an oil filled cable to allow the maintenance of a preset pressure during temp. variations caused by load and weather conditions. The pressure is kept sensibly constant by a gas in the expansion chamber, separated from the oil by a diaphragm. For the diaphragm to be proof against diffusion of gas through it and into the oil, it is pref. made of metal. To give the required flexibility the metal sheet is deformed such that it can expand in two preferred directions. This can be done by six sided indentations (21) in the diaphragm material (20). The diaphragm is pref. in the form of a hemisphere, fixed inside a container, with oil on one side and gas on the other.
Patent DE-2940387-A1 (DE)
Title: Low-temp. pyrolysis of oil shale - with indirect heat transfer from fluidised-bed combustion of pyrolysis residue
Inventor: NOACK ROLF DR ING
IPC: C10B53/06
Filed: 1979-10-05
Abstract: Process and appts. are claimed for the low-temp. carbonisation of oil shale. Shale pref. flows downwards in vertical channels, and obtains at least part of the required heat by indirect transfer, using gas or vapour heat carriers, from the combustion of carbonisation residues in a separate zone. Heat carrier may be the combustion gases from this latter zone, or it may be a material which is heated indirectly there and circulates between it and the carbonisation zone. Combustion zone may be a fluidised bed, which coils for the heat carrier material which abstracts sufficient heat to maintain the bed at 700-900 deg.C. Process utilises internally the energy content of the carbonisation residues more simply and reliably than in previous known methods, e.g. the mixing of the hot solids from combustion with fresh shale.

The regulator may have an additional cursor (2a) cooperating with a heating timer switch (11).

Title: Contact pressure sensor - with dielectric enclosed between two contact layers
Inventor: BETZ DIETER DIPL ING
IPC: G08B13/10
Filed: 1980-02-22
Abstract: Contact pressure sensor, for use e.g. as a burglar alarm, or for impact counting, consists of a dielectric which is enclosed between two electric feelers, one of them earthed and the other connected to an electronic circuit.

Title: Automatic answering machine for telephone subscriber's appts. - has digital memory supplying speech synthesiser accommodated in standard telephone case
Inventor: WEGENER SIEGFRIED
IPC: H04M1/64
Filed: 1980-03-18
Abstract: The principal application of the proposed instrument is to telephone subscribers appts. where the pre-recorded messages are short. A digital memory is incorporated in the telephone circuit in which several different messages can be recorded. The memory output is to a speech synthesiser which converts the digital message into analog signals for transmission. The instrument has a switch for selecting which message it is desired to transmit automatically. As the recorded messages are assumed to be short the memory space required can be incorporated in, or taken from, the facility for storing often used numbers. The instrument typically also incorporates a switch for blocking or unblocking the automatic answering facility. An instrument with push-button number selection is the most readily adaptable for incorporating the propsed answering facility.

Title: Heat regulator for central heating radiators - has rotor with calibrated openings, selectively operated to control flow through radial supply tubes
Inventor: HOLZMANN KARL
IPC: G05D23/02
Filed: 1980-05-13
Abstract: The method of controlling the flow of heating medium to central heating radiators, uses a rotary distributor valve. This has a circular body with a set of discharge tubes (12a to d) radiating outwards from it and a tangential inlet tube (11) at one side for the heating medium. Inside the body is a rotary sleeve with calibrated openings (13d) through it for connecting the heating medium supply to selected discharge tubes so as to control the quantity of heat supplied, the tubes being of different sizes. The rotor can be operated manually or by a press button control system, and can be thermostatically controlled, or by a timing system. An electric motor or electromagnetic drive may be used. A pressure or loading system can be included so that only a small force is required to operate it.
