Title: Improvements in or relating to the production of electrical resistors
IPC: H05K3/10
Filed: 1948-11-12
Abstract: An electrical circuit is printed on an insulating surface by applying a pattern in a finely divided conductive material substantially free from a permanent binder and then applying heat and pressure to at least the coated areas to cause the conducting particles to cohere together to form a conductive path which is partially embedded in the insulating material.  The printing is carried out by using a slurry containing the finely divided conductive material and a volatile diluent.  A small proportion of a less volatile organic solvent may also be present.  A circuit may be printed on polystyrene using the off-set printing method, the printing block being inked with a slurry containing 50 per cent silver, 20 per cent triethanol-amine alginate and 10 per cent ethylene glycol.  The print is sprinkled with finely divided silver, the surplus being brushed off before pressing at 150 DEG C and 500 lb./sq. in. for 0.5 sec.  The sheet is finally washed. A print may be made on a phenol formaldehyde laminate using the silk screen or stencil process.  The slurry in this case contains 70 per cent silver, 5 per cent monoethanolamine and 25 per cent methanol. The print is partially dried by infra-red heating and then pressed at 210 DEG C and 1000 lb./sq. in. for 4 secs. before washing.  The pattern may be applied to a silicone laminate coated with a copolymer of vinyl chloride.  After drying and pressing the whole is baked at 150 DEG C for 10 mins. to cure the copolymer. Conductors may also be stencilled on to an aniline-formaldehyde resin filled with paper fibres and coated with a urea-formaldehyde varnish.  After drying and pressing the whole is cured. Specifications 638,149, 672,255, [Group XXXVI], and 672,260 are referred to.

IPC: G01F25/00
Filed: 1972-06-21
Abstract: 1350345 Measuring fluid flow DART INDUSTRIES Inc 21 June 1972 [23 June 1971] 29108/72 Heading G1R To measure the flow rate of a liquid such as a catalyst slurry being pumped into a receiving vessel 28, valve means 16, 25 is first set by an actuator 40 into a first position in which it directs flow from the pump 5 to an opening 9 in a cylinder 7, containing a piston 8 adapted to reciprocate under the action of the liquid between openings 9 and 10, while simultaneously directing flow from the opening 10 to the vessel 28, a timer 15 is set to time a predetermined period during which the valve means remains in its first position and the piston is driven towards opening 10, the actuator 40, after the timer has timed out, switching the valve means 16, 25 to a second position in which flow is directed from the pump to the opening 10 while simultaneously directing the flow from the opening 9 to the vessel 28 to drive the piston back toward opening 9, and the displacement of the piston in the cylinder is measured. Preferably an extension 72 of the piston magnetically entrains a set of levers (75, 76, 83, 84, 85) mechanically coupled to a pointer 79 and pneumatically coupled via a line 81 to a chart recorder 12 calibrated to read mass flow rate. If the volume of the cylinder 7 is known, the distance moved by the piston in a predetermined time period is a measure of the liquid flow rate. The measuring cycle is continuously repeated and recorded. An electric switch 47 and relay 46 control the operation of the timer 15 and a solenoid coil 41 which operates the actuater 40 pneumatically controlling the valve means 16, 25. A further switch 55 is provided for safety, e.g. if the timer should fail to time out, and operates if the pneumatic signal on line 81 exceeds a set level to return the piston to its starting position.

Title: A variable speed gear or torque converter
IPC: F16H33/08
Filed: 1927-11-01
Abstract: 305,155. Democratis, A. J. Nov. 1, 1927. Variable-speed and reversing gearing comprises planetary centrifugal masses such as W<2>, Fig. 5, which shift bodily across a driven disc A<x> so that as the centrifugal force reverses, instead of being applied at C, it is applied at D. Its effect is thus added in driving the disc. An arrangement is shown in Fig. 9 having a single such mass e, the bearing block c of which moves in a cross slot b in driven disc. Torque is applied at d through a flexible driving-shaft. An impulse N has just been given to the disc at the foot of the slot acting towards the left. When mass e moves far enough for an eccentric boss i to pass a retainer g, the block c passes by centrifugal force to the top of slot b, and the mass e exerts an impulse to the right turning the disc in the same direction as before. A pair of masses such as W<1>, W<2>, Fig. 5, geared to rotate oppositely are preferably used as such a pair produces a reversing impulse along a straight line. Fig. 3 shows the scheme of the embodiment shown in Figs. 10, 12, and 13. Masses B<2>, B<2> rotate in opposite directions about point C which reciprocates in an arc about pivot C<2> as centre, which arc corresponds to the cross slot in Fig. 5. The inertia effect is to push link C' when C is raised and to pull that link when C is depressed. In Fig. 10 the revolving mass system is duplicated and each comprises a pair of masses 28 connected by a gear train 26, 27 so as to rotate in opposite directions. The system is journaled in a U- shaped oscillator 14 corresponding to link C<1> of Fig. 3 which is pivoted at 13 and 16 upon revoluble driven disc member or casing 3. Secured to driving-shaft 1 is a crank-shaft 6, Fig. 13, with a crank 6<a> connected by a double link 11, Fig. 10, to two cranks 9 which through gears 18, 19 drive the two pairs of masses. The oscillation of the U-members 14 is effected by eccentrics 36, 37, Fig. 12, which act through links 51 upon arms 52 of the oscillators 14. The eccentrics 36, 37 are connected to the driving- shaft in two opposite phases for forward and reverse driving respectively by means shown in Fig. 13. A clutch head 43, having a square sliding connection 42 with shaft 6 can be engaged alternatively with two opposite recesses 44, 45 when a rod 46 is displaced by a collar 49, Fig. 10, sliding on the driven shaft 5. The gear ratio varies automatically, and if the resistance is low enough, the gearing turns solid. The crank linkage 6a, 11, 9 may be replaced by toothed wheels.

Title: An improved electrical device and method of determining distances
IPC: G01S13/08
Filed: 1929-09-27
Abstract: 340,531. Measuring distances by reflected waves. THORNTON, A. A., 7, Essex Street, Strand, London.-(Radio Frequency Laboratories, Inc. ; Boonton, New Jersey, U.S.A.) Sept. 27, 1929, No. 29367. [Class 37.] The proximity of a surface or object is indicated electrically by constantly radiating waves from a transmitter and observing the effects produced by reflected waves on the radiating circuit. The distance between two stations, the height of aircraft, or the depth of submersible craft may be determined. As shown, for indicating the height of aircraft, a thermionic oscillator T is adjustably coupled to antenna on the craft by a coil L, a battery C being provided for grid bias and also in conjunction with a variable resistance R for balancing the normal steady anode current so that the meter M reads zero when the reflected energy is a minimum. The usual interference effects between radiated and reflected waves produce deflections in one direction or the other on the meter. The meter may be located in the grid circuit or it may be substituted by a radio-frequency thermocouple in the antenna. The oscillator may be enclosed within a screen S to which it may be capacity-coupled as at C<1> and directly connected as at 2.

Title: Heat resistant electrically conducting compositions, method of coating articles therewith and articles produced thereby
IPC: H01C17/065
Filed: 1961-08-16
Abstract: Electrically conductive compositions comprise a heat-resistant, thermosetting, electrically nonconductive binder and finely divided granular carbon, silver and iron in defined individual proportions between total pigment volume concentrations of 22 and 53%.  The coatings may be applied to insulating bases, e.g. to form heating panels or elements.  Suitable binders are phenolaldehyde resins, e.g. plasticized with tricresyl phosphate, or a silicone resin, or a mixture of at least 25% by weight of silicone resin with a phenol - aldehyde, urea - formaldehyde, polyacrylic ester, or silicone-alkyd copolymer.  The silicone resin may be an alkyl, aryl or alkylarylone, and may carry halogen-substituted radicles.  Optional ingredients of the compositions are antioxidants, e.g. butylated hydroxy toluene; a levelling agent, e.g. lecithin; a dryer, e.g. cobalt octoate; fillers or colouring matters. Solvents may be added to aid application.  A composition, typical of a number exemplified contains 16-52% graphite powder, 14-46% silver powder, 11.02% sponge iron powder, 34.5%, silicone resin, 0.6% cobalt octoate, 1.7% lecithin, 0.4% butylated hydroxytoluene and 20.8% xylene.ALSO:Electrically conducting coatings containing an insulating thermosetting resin as binder for a mixture of granular silver, carbon and iron is applied by spraying, brushing, roller coating or dipping to a base to form an electrical conductor, e.g. a heating panel.  If the base is electrically conducting, it must first be coated with an insulating composition.  Suitable bases are glass, plaster, asbestos, glass-reinforced plastics, ceramics, enamelled metals.  If desired, a non-pigmented undercoat may be applied even to a non-conducting base, and a nonpigmented resin coating may also be applied as overcoating to the conducting coating. In a number of the examples, specified coatings are applied to vitreous enamelled steel plates and cured by heating.

Abstract: 391,779. Shock-absorbers. LUCAS, Ltd., J. and PITT, H. W., Great King Street, Birmingham. Oct. 26, 1931, No. 29659. [Class 108 (iii).] A shock-absorber for motor vehicles includes a cylindrical body part a, a flexible reaction piece f adapted to form a fluid reservoir g in the body part and a vane d with which the reaction piece co-operates. The reaction piece f is made by bending a resilient metal strip or it is made from a pair of superimposed strips. In one form, the abutting ends of the strip are arranged over the vane and the gap k, Fig. 1, between them is closed by a thin cover strip l shaped, e.g. by the provision of gaps in its edges, so that the free movement of fluid within the reservoir is not impaired. Fluid passes from the reservoir g into working chambers h, i through non-return valves m and passage of fluid from either working chamber to the other by a restricted clearance between parts of the vane d and the reaction piece f which may be provided by making the piece f concave in the direction of the axis of the vane spindle and an additional small leakage may occur between the ends of the vane and the body part. The clearance between the parts f, d is regulated by a screw n which presses the parts together and which may also serve to close the filling aperture, washers o being provided to prevent leakage of oil. In a modification the strip l is dispensed with and the non-return valves consist of flaps r, Figs. 3 and 4, in a strip p coextensive with the piece f. In a further modification the piece f is formed integrally with the body part. The body part may be closed in the manner described in Specification 391,778.
