Title: Electrical insulation system
IPC: H05K3/28
Filed: 1973-12-21
Abstract: 1452337 Printed Circuits XEROX CORP 21 Dec 1973 59534/73 Heading H1R Substantially closed cell foam or microcellular material 14, inert to ozone, is mounted in close proximity to points of potential discharge such as at the ends of the connections I 1A, 12A of components 11 and 12 on the printed circuit board 10. The material 14 may be of neoprene, polyethylene, a polyvinyl chloride. Such material is said to be more efficient in suppressing corona discharge than the non-resilient and generally open-cell plastics material which has been previously suggested for reducing damage due to vibration, and also prevents egress of water vapour to the electrical connections.

Title: Method of and system for attenuating multiple seismic signals in the determination of in-line and cross dips employing cross steered seismic data
Inventor: JUDSON ROGER D
IPC: G01V1/28
Filed: 1969-12-30
Abstract: 1,270,590. Seismic exploration. CHEVRON RESEARCH CO. 30 Dec., 1969 [30 Dec., 1968], No. 63388/69. Heading H4D. In a system for the collection and processing of seismic data to obtain a good primary-tomultiple reflection signal ratio and enable both the "in-line dip" and "cross-dip" (relative to a survey line) of subsurface strata to be determined, seismic energy is generated in turn at source points spaced along a first line and records are made of the outputs of detectors spaced along a second line oblique to the first line. One of the lines is substantially parallel to the survey line; the other line is one of a series of oblique lines at a common oblique angle to the survey line. The source points and detector locations are such that (a) the centre points, each midway between the source and detector locations associated with a respective recorded trace, form a two-dimensional grid and (b) corrected traces produced by applying static and dynamic corrections to the recorded traces contain cross sets of traces associated with centre point alignments substantially perpendicular to the survey line, at least two traces of a cross set having been obtained using appreciably different source-detector spacings. A "beam-steering" process is then applied to each cross set of traces by differentially delaying the traces to produce traces which are "directional" and in which multiple reflections are attenuated. The system, including the processing and display of the recorded signals, is similar to that of Specification 1,245,041 except for details of the field procedure involving oblique sourcepoint and detector arrays. In the Fig. 1 example the source is at points S1-S6 in turn, then S1<SP>1</SP>-S6<SP>1</SP> in turn etc. on lines 13, 14 etc. to one side of survey line 11 and a "roll-along" data collection method may be used with a 36- geophone array on line 11, thereby defining centre points C1 &c. In other examples the source point lines extend both sides of survey line 11 (Fig. 13, not shown) or to one side and the other in alternating sequence (Fig. 14, not shown).
Patent GB-773046-A (GB)
Abstract: 773,046. Dampers. AKTIESELSKABET C. M. HESS' FABRIKKER. Oct. 11. 1955 [July 11, 1955], No. 28937/55. Addition to 725,059. Class 126 The air supply to a solid fuel stove is controlled by two thermostats, one mounted in the lower part of the stove and influenced only by the temperature of the air flowing into the stove from the room and the other influenced by the temperature of the smoke, both controlling a single damper which is normally biased'towards its closed position, and the thermostat influenced by the temperature of the air in the room is connected to the damper by a non-return connection. As in the parent Specification a coiled bimetallic strip 34 is mounted in the lower part of the outer casing of the stove below the ash space 14 and a straight bimetallic strip .46 is mounted in a recess 44 extending into the stove above the fireplace. A radial arm 32 on the lower bimetallic strip 34, Fig. 2 engages the lower arm of a lever 24, carrying dampers 20 and supported on a knifeedge 26 so that the dampers 20 tend to close under gravity. The upper end of the lever 24 carries a pin 48 moving freely in a slot 50 in a bracket carried by the upper straighf bimetallic strip 46. The length of the slot 50 is such that the upper thermostat operates only to close the damper 20 if the stove becomes over-heated, or to open the dampers if the rate of combustion falls excessively. Two air inlet apertures 18 in the air inlet box 16 are controlled by twin dampers 20 which are pressed in opposite directions by the incoming air stream so as to prevent chattering.

Title: Sets of golf clubs
IPC: A63B53/00
Filed: 1978-09-22
Abstract: In a matched set of golf clubs the mass of each club head is so distributed as to establish a generally oval shaped "sweet area" on the striking face wherein impact with the ball at a predetermined head velocity results in a carry of at least 90% of that obtained when impact at the same head velocity is made with the "sweet spot", namely the point on the striking face which on impact with the ball will propel it for the maximum distance for any given head velocity, the major axis of the "sweet area" being horizontal or upwardly inclined from the heel towards the toe at an angle of not more than 7 DEG . Empirical methods of ascertaining and adjusting the "sweet area" in prototype clubs are described.

Title: Bubble blowing gun
IPC: A63H33/28
Filed: 1979-02-28
Abstract: A bubble blowing toy comprising a casing 2 in the shape of a gun or pistol, a nozzle 6 adapted to be dipped into bubble liquid and thereby retain a film of liquid across a detachable ring 20, and a bellows in gas flow connection with the nozzle. The bellows are contained inside the casing and a lever is provided, a trigger part 4 of which projects from the casing. When the trigger is pressed the lever acts on the bellows via an axial guided sliding rod and compresses them, producing a puff of air through the nozzle 6. This puff of air causes bubbles to be fired from the ring 20 on the nozzle 6 of the gun. Fins 20 on the ring retain liquid and allow for several bubbles to be blown without recharging with liquid. <IMAGE>

Abstract: In a method of dyeing cellulosic fibrous material a compatible polymer precursor, preferably polymerisable within the material and containing basic groups such as urea-formaldehyde and melamine- formaldehyde precursors of resins particularly hexamethoxymethyl melamine, with which at least one acid dyestuff is substantive, is incorporated in a liquid phase so as to be in at least a potentially fast and evenly distributed relationship with the structure of the material and the dyestuff and the liquid then dried off. The incorporation of the precursor and the dyestuff may be carried out as parts of the same step or successively and cross linking of the polymer and structure may be effected or completed in an appropriate after treatment.

Patent GB-2063538-A (GB)
Title: Presence detector apparatus
IPC: G08G1/042
Filed: 1979-10-17
Abstract: A presence detector apparatus, particularly for vehicles, has an inductive sensing loop (12) connected in an oscillator circuit (10). Discriminator circuitry (18) provides an error output representing the time difference between a certain number of oscillator cycles and the delay afforded by a time delay device (20) such as a monostable activated by the oscillator output. The error signal is applied in a negative feed- back loop, preferably including an integrator, that controls the delay of the time delay device (Fig. 1) or the oscillator frequency (Fig. 5) so as to act to hold the discriminator operative at a fixed point of its characteristic. The discriminator has a characteristic providing a rapid change of error signal with changes of oscillator frequency due to movement of a vehicle in the vicinity of the sensing loop. Detect circuitry (22, 34) is responsive to the error signal to signal the presence of a vehicle at the sensing loop. <IMAGE>

Title: Reducing i.c. engine intake manifold vacuum at overrunning
IPC: F02M23/06
Filed: 1980-06-09
Abstract: A non-explosive gas (e.g. air) is supplied to the inlet manifold (2) under the control of a valve (13) which is normally closed and is operated by an electrical actuator (16) energized through a circuit including a first switch (19) which closes when the engine speed rises above idling speed and a second switch (20) which closes when the accelerator control moves to its non-operated position. When both switches are closed the valve (13) is opened to admit gas to the manifold, causing the partial vacuum to collapse and thereby preventing fuel from the carburettor (3) reaching the combustion chambers. A further switch (22) may be included in the circuit for protecting a vacuum- braking system by opening when the brake vacuum is below a predetermined value. <IMAGE>
