Patent DE-3243334-A1 (DE)
Title: Bushing for measuring electrodes in high-pressure containers
Inventor: BECKER PETER DR RER NAT
IPC: G01N27/28
Filed: 1982-11-19
Abstract: The bushings for measuring electrodes used to carry out investigations, i.e. both individual measurements and continuous monitoring of the properties of aqueous solutions or gases under high pressure (up to about 1000 bar = 1000 MPa and above) and high temperatures (around approximately 300 DEG C) have to be specially designed. The type of insulation must be such as to prevent any potential equalisation between electrode and container and the electrically insulating material must also be resistant to the effect of temperature and chemicals. Finally, it is not only important that the detachably interconnected individual parts ensure a pressure-tight seal. A bead-type body, which is securely attached to the electrode and is clamped in the receiving bore, prevents, in particular, the possibility that the electrode might be pushed out through the bushing as a result of the high pressure.

Patent DE-3247235-A1 (DE)
Title: Electronic heat meter
Inventor: RITTER HERMANN ING
IPC: G01K17/12
Filed: 1982-12-21
Abstract: The invention relates to an electronic heat meter, which operates according to the dual-slope principle and has one PTC thermistor in each of the feed and return lines of a heating system (solution). After a preselected quantity of heat transfer medium has passed, a flow (flow-rate) meter emits a pulse which sets a memory, as a result of which an analog circuit and a clock-pulse generator are connected to the supply voltage. The clock-pulse generator is connected to a digital circuit which controls four electronic analog switches in the analog circuit, of which two are simultaneously controllable four-stage analog switches to which the reference resistors and PTC thermistors are connected. The analog circuit consists of an integrator, which can optionally be bridged by the electronic analog switch, and a downstream comparator. The great advantage of this circuit is the low power consumption and the elimination of the offset voltage adjustment (balancing).

Title: Arrangement for the combustion of high-viscosity heating oils in multi-stage pressure-atomising burner plants
Inventor: FRUENKE STEFAN
IPC: F23K5/04
Filed: 1983-03-11
Abstract: The invention relates to an arrangement which makes it possible to burn high-viscosity heating oils with a pour-point greater than the ambient temperature in pressure-atomising burner plants with multi-stage operation. The aim of the invention is to combine together tuyeres which are known per se to result in sufficient preheating of the components through which the heating oil reaches the nozzle. The object is achieved in that the additional tuyeres and the tuyere with a pressure-adjustable valve have preheated heating oil flowing through them successively or simultaneously in either parallel or series arrangement in a preheating circuit, the inlet connection and outlet bores or overflow bores being arranged in such a way that an optimum heat transfer is achieved.

Title: Circuit arrangement for switching electrical loads on and off and monitoring them
Inventor: HAUBNER GEORG
IPC: H02H3/087
Filed: 1983-10-26
Abstract: A circuit arrangement is proposed which has the object of both switching loads on and off and also monitoring them, by means of a high-power field-effect transistor (28). The voltage drop on the field-effect transistor (28), which voltage drop is dependent on the load current, is for this purpose supplied to a threshold switch (33) whose switching state is sensed at two predetermined times during the switching-on process of the load, and whose switching threshold is set such that it is exceeded by the switching-on current at the first sensing time when the load is intact, and such that it exceeds the normal operating current at the second sensing time. In this case, the monitoring circuit (13) emits a signal as a function of the sensed switching states of the threshold switch, which signal indicates an interruption, an overload or a short-circuit, as well as an intact load circuit. The circuit arrangement can be used for monitoring loads having an increased switching-on current, preferably for incandescent lamps, motors and magnet coils (Figure 2). <IMAGE>

Patent DE-3344361-A1 (DE)
Title: Screwing or inserting tool with universal handle for various bits
Inventor: SCHWARZ RALF
IPC: B25B13/46
Filed: 1983-12-08
Abstract: A screwing or inserting tool of the universal-handle type with interchangeable inserts, e.g. hexagon sleeves, square sleeves, extensions, screwdrivers or the like, provides for a roller or ball overriding clutch - instead of the known ratchets - as a drive element in the rotatably mounted location head. This ensures that any stroke movement is converted into an effective working stroke upon actuation. The force is introduced centrally and is symmetrically distributed. Serving to reverse the rotary movement (effective clockwise or anticlockwise rotation) are adjusting fingers which are mounted outside the chambers and, depending on the direction of thrust, displace the clutch elements from their working position. A further development provides for a single working direction, in which case tools can be slipped on on each end face of the clutch body. Clockwise or anticlockwise effectiveness is obtained by transposing the respective tool.

Title: Adjusting device for the swivel axis of a throttle valve
Inventor: SAUSNER ANDREAS
IPC: F02D9/02
Filed: 1984-02-03
Abstract: In an adjusting device for the throttle valve (3) in a throttle valve housing (1) a return spring (8) acts by means of a bowden cable (9) on a cable sheave (7), the radius of which decreases as the opening angle of the throttle valve (3) increases. As the opening angle widens, the spring tension thereby increases less than in the case of a small opening angle of the throttle valve (3). The result of this is that the counterforces on the accelerator pedal (4) do not increase to an undesirable extent even when a linear return spring (8) is used. <IMAGE>
