Patent EP-0017343-A1 (EP)
Inventor: O'BRIEN RICHARD ANTHONY
IPC: H03K3/30
Filed: 1980-03-04
Abstract: A radio frequency generator comprises a set of switching transistors (1 to 4) which drive a radio frequency filter (5,6) of which an inductor (6) is tightly coupled to a coil (15) which feeds a bridge rectifier (17). The rectifier (17) is biassed by the source of direct current and begins its rectifying action when the load current becomes excessive. The load current becomes excessive as a result for instance of mismatch of the antenna (7,8,9). The arrangement provides protection against high load currents and thereby protects the switching elements (1 to 4) from damage.

Abstract: A wiper for wiping the interior of drill pipe, for example, of drilling mud. The wiper has an elongate float (18) from the top of which extends a mandrel (16) carrying flexible pipe-wiping assemblies (48, 50). The mandrel flexes with respect to the float to allow the wiper to negotiate bends in the pipe. At the bottom of the float there is a passageway (102) which allows communication between the hollow float interior and the exterior for the purpose of pressure equalisation.

Abstract: An improved process for catalytically dewaxing a hydrocarbon oil is disclosed. In this process the waxy oil is contacted in the presence of hydrogen with a dense zeolitic dewaxing catalyst associated with a nickel-tungsten hydrogenation component. The dewaxed oil has unexpectedly good stability and a low bromine number compared with oils processed with prior art catalyst. The process may be used to dewax crude oil, fuel oil fractions and lubricating oils.

Abstract: An aluminium complex is disclosed of formula (II):
     where ―O― bridges two aluminium atoms, R is an alkyl group and X is a substituent derived from alcohols, phenols, enolates, carboxylic acids or esters thereof, hydroperoxy compounds or other monovalent radicals comprising an element other than carbon linked by an oxygen atom to aluminium. 
     The complex may be prepared by reacting an aluminium alkoxide with a compound containing the substituted X and then condensing the resulting substituted aluminium intermediate with a deficiency of water or carboxylic acid. The complexes form airdrying compositions with synthetic resins such as alkyd resins.

Abstract: The apparatus comprises a fixed head (3) mounted on a rotary head drum (1), and a movable head (5) supported on the head drum (1) so as to lag the fixed head (3) by a predetermined phase, and mounted on a bimorph plate (4) so that the position of the movable head (5) can be controlled transversely of a skew track on a magnetic tape (2). A delay circuit (24) matches the phases of the signals reproduced by the fixed and movable heads (3, 5), and in dependence on the levels of the reproduced signals the scanning path of the movable head (5) is adjusted relative to the scanning path of the fixed head (3) such that a reduction in one reproduced signal level causes an increase in the other reproduced signal level when the reproduced signals are phase-matched. The output is then complemented by at all times selecting the higher level reproduced signal with a selection switch (25).

Inventor: THOET REINHOLD DIPL-ING
IPC: H03K19/007
Filed: 1981-01-10
Abstract: Circuit arrangement for a fault-tolerant logic module. The circuit arrangement provides:   a) that the input signals are supplied to separate input transformers and are rectified in their secondary circuits by means of inserted rectifier arrangements,   b) that the rectified input signals form the individual control potentials for a subsequent transistor blocking oscillator circuit with feedback transformer,   c) that the pulse voltage of the blocking oscillator is supplied to the output via an amplifier stage inserted in the secondary circuit of the feedback transformer. For generating a programmed drop-out-delayed signal, a temperature-stabilised circuit arrangement is achieved by the fact that a fail-safe AND gate modified by a clock generator (G) at one input and a fail-safe OR gate are connected to one another in such a manner that the input of the AND gate, to which the input signal is applied, is connected to the input of the OR gate, that the output (A) of the OR gate is fed back to the input of the AND gate to which the clock generator (G) is connected, that the output of the AND gate is conducted to a rectifier circuit (GR), that the AND gate, like the OR gate, is in each case provided with a capacitor (CT1, CT2) for maintaining a time-limited control potential, and that the clock generator (G) contains a KUJT flip flop circuit. If component faults occur, the programmed drop-out delay time of the circuit should only be shortened or disappear. <IMAGE>

Date Oct. 14, 1982.A respirator device especially for the respiratory treatment of new-born and inmate infants and for their adaptation to natural breathing. The device comprises oxygen and air ducts, means for adjusting the composition, temperature, humidity, and other parameters of the gas mixture, a patient junction, and pressure adjusting valve means coupled to the junction shunting the gas flow in the junction in such a way that the gas pressure is positive both during expiration and inspiration. The respiration demand of the patient is sensed by a means responsive to pressure drops which controls a starting signal generator and a beat generator. The beat generator controls the valve means. The device can be adjusted to controlled respiration, controlled assisted respiration, inspected and assisted respiration, and continuous positive airway pressure modes, whereby it can be adapted to various respiratory diseases. In the inspecting modes a respiration stoppage detector senses the spontaneous inspirations and in response to a stoppage exceeding a predetermined waiting period, performs controlled respiration for a given period of time and starts an alarm.

Abstract: A plough beam 4 is coupled to a tractor chassis 1 by a three-point linkage having a top link 9 and two bottom links 3. The top link 9 is a double acting control ram 23 which has hydraulic couplings 26, 28, 25 and 27 which cross-couple the control ram 23 to a double acting sensor ram 21 so that expansion of one ram produces contraction of the other. The sensor ram 21 is coupled between a pivot 17 at the head of the lift rod 18 of a conventional lift mechanism for the plough, and a pivot 22 on the tractor chassis. Movement of the lift rod 18 due to height variation of the plough beam 4 actuates the sensor ram 21 to vary the length of the top link 9, so as to vary the pitch attitude of the plough. Good land profile following is achieved by a high rate of change of pitch at normal working depth. A lower rate of change is achieved as the plough is raised out of work.

Abstract: In a fluid control throttling valve assembly (13) for varying the throttling cross sectional area of flow as a function of valve shaft angle the valve includes a smoothly convergent surface (14) directly upstream of the throttling cross sectional area, an expansion chamber immediately downstream of the throttling cross sectional area to produce a fluid mechanically disruptive and very high expansion ratio sudden expansion directly downstream of the vena contracta of the flow so that the recirculating fluid (18) downstream of the throttling cross sectional area, with which the vena contracta flow interacts, is relatively low velocity and a downstream cusp face (17) curving so as to stabilize the recirculating flow whereby the merger of the convergent flow past said throttling cross sectional area of flow with the downstream entrained recirculating flow produces a substantially constant vena contracta area and thus a constant coefficient of discharge over the relevant operating Mach and Reynolds number range, of said throttling valve.

Abstract: A single-chip microcomputer device contains on-chip program storage in a read-only memory (17), and this program may be corrected or uptaded by patching. The ROM addresses are applied to an off-chip memory device (44) containing one bit for each potential ROM address, and each bit is set to mark the beginning address of code to be patched; an interrupt is signalled when one of these set bits is accessed by an address occurring during operation of the microcomputer. The interrupt causes the processor to branch to an off-chip program memory (40) to insert the patch code. The patch ends in a branch back to the on-chip ROM.
