Inventor: LUPTON WILLIAM GEORGE
IPC: E01C23/09
Filed: 1988-07-04
Abstract: The invention comprises a road cutting equipment for cutting grooves, or slots in road surfaces (40) and comprises an apparatus (18) attached to an end of a vehicle (10). When the apparatus (18) is not in use it is raised clear of the road surface (40) so that the vehicle (10) can travel over the road surface (40) in normal fashion. When the equipment (8) is to be used it is lowered relative to the vehicle (10) and the vehicle (16) is supported by the equipment (18) on legs (42, 44) of which the lower ends have rollers (52, 62). At the same time a cutter disc or drum (32) is driven and penetrates the road surface (40). The equipment (18) in this condition is driven forward, by a drive means (66) which directly drives one or more of said rollers (62).

Abstract: Field-effect transistor which comprises, apart from the source, gate and drain electrodes, an additional electrode. 
<??>In this device a semiconductor body (1) carries source (2), gate (3) and drain (4, 5) metallisations which define a main transistor. The metallisation of the drain is separated into two parts (4 and 5) which are separated by a channel on which is placed a metallisation (6) for a second gate, defining a secondary transistor (4 + 5 + 6). The two parts (4 and 5) of the drain are coupled by this secondary transistor whose channel is separated from the main channel. The secondary transistor (4 + 5 + 6) makes it possible to control the gain of the main transistor, or amplitude-modulate its signal or mix two frequencies addressed to the two gates (3, 6). 
<??>Application to signal processing, in particular in hyperfrequency.

Abstract: A particular branched chain polyalkylenepolyamine ("PAPA") having plural amine groups including a secondary amine group intermediate terminal free primary amine groups (that is, neither one is hindered), and having at least two C atoms between each group, may be selectively cyclized with a ketoform reaction to form a polysubstit­uted piperazinone ("PSP"), with specific directivity. Such PSPs are linked to a triazine nucleus to yield pip­erazinone-triazine ("PIP-T") compounds which are excel­lent stabilizers for polyolefins and other light-degrad­able polymers. Certain acyclic polyalkylenepolyamines may have a PIP-T substituent at each N atom forming pend­ant PIP-Ts ("P[PIP-T]" for brevity) which are also excel­lent stabilizers, and like some of the PIP-Ts, some P[PIP-T]s provide photostabilization without noticeably interfering with the color of films and fibers provided by even pastel-colored pigments and dyes.

The nickel plates, tungsten base alloy plate and metal shaft are brazed together by way of respective brazed joint layers (14, 15, 16) of the composition which does not include titanium. A metal sleeve (9) is installed on the shaft of the ceramic turbine wheel, metal shaft and the metal plates. The metal sleeve is brazed to the metal shaft by way of a brazed joint layer (30) of the composition including less than 1 wt% of titanium. The brazed joint layer for brazing the metal sleeve and metal shaft together is formed by the filler metals for forming the brazed joint layers for brazing the nickel plates, tungston alloy plate and metal shaft together.

Abstract: An output circuit of a semiconductor circuit has a reverse bias voltage generator which comprises a ring oscillating circuit, a reverse bias voltage generating circuit and a switching circuit. The output circuit is of the type having first and second output N-(P-)channel MOS transistors connected in series, an output terminal being provided at the intermediate position of the transistors. The ring oscillating circuit is activated for oscillation only when an output enabling signal is of a zero potential indicative of disabling outputting of an input data signal. The reverse bias voltage generating circuit generates a reverse bias voltage lower (higher) than the ground potential based on the oscillation output of the oscillating circuit. The switching circuit supplies a reverse bias voltage to the gate of the first output N-(P-)channel MOS transistor only when a bias instruction signal, i.e., a complementary signal of the output enabling signal, is of a positive (negative) potential, whereby the occurrence of ionization current in the first output N-(P-)channel MOS transistor can be effectively prevented even when a negative (positive) voltage is applied to the output terminal.

IPC: A61B5/03
Filed: 1989-10-06
Abstract: An intrauterine catheter tip pressure transducer is disclosed constructed as to have outside dimensions extremely minute and having a substantially uniform outside diameter throughout its entire length. The transducer comprises an electronic sensor (40) of the etched diaphragm type, comprising a piezoresistive die or chip having dimensions of about .080 inches square and which is mounted in the distal end (18) of the catheter (10). One side of the transducer diaphragm is acted upon by the pressure within the uterus and the other side of the diaphragm is placed at a known reference pressure, preferably atmospheric pressure. A passage (28) is provided within the interior of the catheter (10) for applying the reference pressure to the transducer. The sensor (40) is directly mounted to an annular frame (20) at the distal end and surrounded by a cylindrical sleeve (30) that is crimped to the catheter tubing (12). Wiring is provided directly to the sensor (40) by ribbon cable (50) passing within the catheter (10) from its proximal end (14) to free ends (52) within the distal end (18) where the free ends (52) are directly bonded, by gold wedge bonding (58), to the pads (56) of the electronic sensor (40), thereby eliminating larger printed circuit boards or conductive tape to make that connection. Thus the overall catheter (10) may have its distal end about 3.3mm in outer diameter with the catheter tubing of about 3.0mm. By the preferred construction, the overall dimensions can be reduced so as to be used with standard sized introducers presently used for intrauterine pressure determinations.

Abstract: A fusion basket (10) having an external, substantially continuous helical V-thread (12) by which it can be screwed into a bore after first forming in the bore mating female threads that bite into the cancellous regions.. Mating of the threads ensures that the fusion basket remains securely in place without compressing or splitting the recipient bone. Eventually, the ingrowth of bone through perforations (13) in the valley (14) of the thread forms a permanent interconnection between the two bony   structures. When used to create bone ingrowth between adjacent vertebrae, the V-thread fusion basket is implanted in pairs on opposite sides of the disc space.

Abstract: An ink jet print cartridge includes an ink reservoir (12), a print head (30) for ejecting ink from the reservoir and first and second pressure control mechanisms for limiting the reservoir underpressure. The first pressure control (36,38) mechanism limits reservoir underpressure by controllably introducing replacement fluid (i.e. air or ink) thereto. The second pressure (27) control mechanism limits reservoir underpressure by changing the volume thereof. The two pressure control mechanisms cooperate to regulate the underpressure in the reservoir at a desired value over a broad range of environmental excursions and permit use of a volumetrically efficient package.
