Abstract: 609,627. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., ROCHE, A. H., and ELLIOTT, T. W. March 19, 1946, No. 8480. [Class 40 (vi)] In a high-frequency amplifier in which cathode feedback is provided between the input and output by means of a network common to the cathode circuits, the cathodes are connected to the corresponding winding of a transformer to one winding of which the feedback network is also connected. By this means it is made possible for the cathode currents of the valves to be individually monitored. The Figure shows a three-stage amplifier in which each stage comprises two valves in parallel. Local negative feedback is provided in stages 1 and 2 by means of the resistancecondenser combinations 31, 37 and 32, 38 and in the output stages by the resistance condenser combinations 35, 41 and 36, 42. In stages 3 and 4 no local negative feedback is provided, the condensers 39 and 40 being of very low impedance at the signal frequency. Resistances 33 and 34 have such a value that a standard voltage related to the D.C. cathode current of valves 3 and 4 can be measured between terminals 71, 72 and earth. The cathode circuits of valves 1, 2, 5 and 6 are coupled to each other and to the feedback network 52 by means of transformer 54 which has four equal tightly coupled windings wound in the same direction. Across the resistances 59, 60, 61 and 62 which are decoupled at signal frequencies by condensers 63, 64, 65 and 66, there appears a standard D.C. voltage which can be monitored at terminals 67, 68, 69 and 70. A standard voltage also appears across resistors 33 and 34. In the event of a failure of valve 6, network 52 is coupled into the cathode circuit of valve 5 by means of the condenser 73. If the windings of transformer 54 are connected in parallel aiding, then in order to maintain the correct phase relationship round the feedback loop an odd number of intermediate amplifier stages is required between the input.and output stages. If the windings associated with the output stage are connected in opposition to those associated with the input stage, an even number of intermediate amplifier stages is required. The provision of terminal 53 enables the characteristic of the feedback network 52 to be controlled if required by an external signal source. The input and output transformers may have associated with them equalizing networks 46 and 51 and the cathode feedback network may be connected to a fifth winding of the transformer 54 instead of to one of the other four windings.

Title: Improvements in and relating to apparatus for delivering liquids in definite volumes
IPC: B67D7/16
Filed: 1925-03-31
Abstract: 256,292. Japy, P. A. J. E. March 31, 1925. Vacuum apparatus.-Apparatus for delivering definite volumes of liquid and operated by vacuum or by gravity, comprises a chamber C<1> provided with an inlet C<3> for the liquid, an outlet valve c controlling the discharge from the chamber C' to a chamber C<2>, and atmospheric and suction ports 4, 3 controlled by a double valve 2, which is moved from one port to the other by floats F', F<2> through spring trip mechanism comprising trip lexers 8, 8<1> adapted to engage notches 5, 5<1> on a cam 6 secured to rocker arms 11, 11<1> loosely mounted on the spindle 1 of the valve 2. When the chamber C<1> is full, the float F<1> lifts the arm 8<1> by means of its rod 9 and releases the arm from the notch 5<1>. A spring r<1> then quickly throws over the rocker, cam and valve to close the suction port and open the chamber C<1> to atmosphere. The liquid then flows through the valve c to the chamber C which is open to atmosphere through a pipe t and is connected to the carburettor. As the level falls in chamber C<1>, the float F<2> descends and releases arm 8 from notch 5 by means of rods 10, 10<1>. The weight of the float F<1> then turns the rocker and cam in the direction of the arrow f<2>, and the valve in the same direction through a spring r<3>, thereby closing the atmospheric port and opening the chamber to suction. The apparatus may work by gravity if the source of liquid is arranged above the level of the chamber C<1>, the liquid being supplied through the port 3 controlled by the valve 2. The apparatus may be used as a meter by registering its pulsation. In another form, a single float operates the valve through the trigger mechanism.

Title: Electrically-conductive spigot and socket joints for pipes, couplings and fittings and gaskets therefor
IPC: F16L25/01
Filed: 1958-03-18
Abstract: 824,833. Joint-making packing. AMERICAN CAST IRON PIPE CO. March 18, 1958 [Oct. 7, 1957], No. 8623/58. Class 122 (3). [Also in Groups XXVIII and XXXVI] A gasket 13, Figs. 1 and 2, for a socket-andspigot-type pipe joint 12, 11 or other coupling is formed from a compressible electrically non- ductive material and is provided with at least one electrically-conductive member 35 extending through the gasket and having portions 36 adapted to make contact with the socket 12 and spigot 11 of the joint and so permit the flow of electric current between connected lengths of pipe. The gasket 13 may be of moulded rubber, preferably formed in two portions 13a, 13b of different degrees of hardness integrally connected on a plane 34. The outer peripheral surface of the portion 13a is formed with a locating shoulder 31 which, together with the remaining surfaces 29, 30, 32, 33 of the gasket, abut correspondingly-shaped surfaces formed in a cavity 14 provided in the socket 12, the cavity being of greater axial length than that of the gasket. The inner peripheral surfaces 27, 28 of both portions 13a, 13b are inclined, the surface 27 being at a steeper angle than the surface 28, and, when the spigot 11 is entered into the gasket, the rubber is compressed until, after the complete insertion of the spigot, the cavity 14 is completely filled. The external surfaces, especially the end face 25 and inclined surface 27, may be reinforced with fabric. In operation, fluid pressure in the pipes forces the softer portion 13b into contact with the spigot and socket surfaces and continued pressure is transmitted to the harder portion 13a thereby causing the tapered face 29 thereon to be forced into greater contact with its seating. In the modifications shown in Figs. 5 and 6 the gaskets 43, 57, which are both formed from uniform hardness rubber, have, respectively, substantially rounded body portions 45, 59 replacing the tapered portion 13b. The outer peripheral contours of the gaskets, which include locating shoulder portions 48, 61, mate with correspondingly-shaped surfaces formed in the cavity provided in the socket of their respective joints. A number of conductive members 50, 63 are spaced around the gaskets.

Title: Direction signaling systems
IPC: B60Q1/38
Filed: 1956-03-20
Abstract: 806,023. Electrically-released switches. HOLLINS, J. R. March 20, 1956, No. 8679/56. Class 38 (5). [Also in Group XXXVIII] A direction signalling system for vehicles comprises a selector switch with means to latch the switch in either operated position and electrically-energized release means effective after a predetermined period of energization to release said latch means, with an energizing circuit for said release means having one terminal connected to the electrical source only when said selector switch is in operated position, and the other terminal connected to ground via a load (e.g. stop lamps) which is connected to said source in the vehicle motion arresting position of a driver-operated control element (e.g. brake pedal), thereby shortcircuiting said energizing circuit to render it ineffective. A selector switch 10 comprises a dielectric base 11 carrying a dielectric disc 20 on a pivot 12 spring-loaded by springs 18 to the neutral position shown, from which it may be displaced by means of an operating lever 15. In the operated position a contact strip 21 on the disc 20 bridges contacts 19 and 23 or 24 on the base 11 to connect the flasher 27 to lefthand or right-hand front and rear signalling lamps LF, LR or RF, RR respectively. A pilot lamp PL flashes when the signalling lamps are thus in circuit. When the disc 20 is turned to an operated position a small button 31 on the end of a bimetallic strip 30 engages a depression 26 in a conductive segment 25 to latch the disc 20. At the same time the battery 16 is connected via the segment 25 and bimetallic strip 30 to a heating winding 35 whose circuit is completed via stop lamp 40. After a predetermined heating period strip 30 bows away from disc 20 to allow it to restore to the neutral position under action of a spring 17, thereby cancelling the direction signal. Should the vehicle be delayed in making a turn (e.g. by heavy traffic) the brake pedal 50 would be held depressed, operating switch 45 to light stop lamp 40. This effectively short-circuits the heating winding 35 during the waiting period and the heating interval does not commence till the brake is released for the vehicle to make the turn, and the signal is thus protected from premature cancellation. The provision of two bimetallic latching strips, one for each direction of turn, ensures that a turn signal shortly following one in the opposite sense is not restored too quickly owing to the latching strip still being warm.

Abstract: 609,872. Mine-chocks. OLD, R. B. March 21, 1946, No. 8716. [Class 20(ii)] A collapsable chockpiece for use in mines comprises an elongated base A formed at each end with hollow portions having downwardly inclined faces 1, 1a which mate with the faces 8 of hollow triangularshaped members B, B<1>. The faces 1, la, 8 are slotted to allow teeth 4a on pawl-like members 4, pivoted at 3 to the base A, to project therethrough and engage projections 9 depending from the top sides of the members B, B'. The pawls 4 are supported in this position by a slidable bar 5 resting on the bottom 6 of the base A and having projecting portions 5a engaging downwardly projecting teeth 4b on the pawls 4. On sliding the bar 5 either way by pulling or striking an extension 5c projecting through a slot 11a in the vertical side of one of the members B, B<1>, the abutments 5a move from under the teeth 4b and the pawls 4 drop allowing the members B, B' to slide down the faces 1, 1a and the part of the chock above the chock-piece to collapse. A projection 5b on the bar 5 limits its sliding movement either way.

Abstract: 1,010,598. Knitting; treating textiles. CELANESE CORPORATION OF AMERICA. March 7, 1962 [March 9, 1961], No. 8750/62. Headings D1K and D1P [Also in Division A5] A cover for a sanitary towel or wound dressing weighs less than one ounce per square yard and is warp knitted from multifilament yarns of less than 150 denier impregnated with a mineral oil-based conditioning agent to provide the fabric with a capillarity factor of from 6 to 9 and preferable 7 to 8. The capillarity factor is the number of centimetres that water will in 48 hours travel up a strip of fabric 3. 2 to 3. 8 cms wide with its lower end immersed in water. The fabric may be knitted on its lower end immersed in water. The fabric may be knitted on a two bar warp knitting machine, the yarns from one bar being knitted into chains while those of the other bar span several needles. The stitch pattern may be such as to form wales along which the fabric is readily splittable whereas other areas are non-splittable either because they are knitted in a different stitch or because they are bonded. The fabric may comprise yarn of 10 to 100 denier and yarn of 10 to 75 denier e.g. of cellulose acetate. The filament deniers are preferably less than 5 and the twist less than 10 and preferably less than 1 turn per inch. One bar of the warp knitting machine may be threaded 1 in 2 out and the stitch pattern may be 1-0, 0-1. The warps of the second bar may have a stitch pattern of (1-0, 3-4 x times), 1-0, 6-7 where x is an integer preferably 1. Other suitable patterns are 1-0, 6-7, 3-4, 6-7; or 1-0, 6-7, 3-4, 6-7, 1-0, 3-4. The second set of yarns may follow a 1-0, 3-4 pattern for about 18 inches and then for about an inch a stronger fabric is formed e.g. as shown in Fig. 1 or by forming stitch patterns 1-0, 3-4, 1-0 respectively on the two bars. Some of the warp threads, preferably some of the chains may be differently coloured to indicate the back of the towel. Alternatively, every 18 inches along the fabric an inch strip may be bonded either solidly or in a pattern of strips, circles or the like. Otherwise all the fabric may be bonded. Bonding of cellulose acetate may be effected by an adhesive, e.g. polyvinyl acetate latex, plasticizers e.g. glycerol triacetate, triethyl citrate di-methoxyethyl phthalate and methyl ethoxyethyl phthalate or aqueous acetone diluted solvent or heat. The conditioning agent may comprise a mineral oil, a partial ester of phosphoric acid with a long chain aliphatic alcohol and an alkylamino ester of a long chain aliphatic acid and an acetate of a polyvalent metal, e.g. aluminium acetate, and preferably includes a water-repellent wax, an emulsifying agent, an alkyl phenol and a lower alkanol. The conditioning agent may be applied by rollers to the yarn.
