Abstract: 731,483. Racquets. ARMALINES, Ltd. April 12, 1954 [May 1, 1953], No. 12170/53. Class 132(2). A toy tennis or badminton racquet comprises a handle 2, a frame 3 attached to it and a moulded lattice work 4 of rubber or synthetic, coloured rubberlike material fixed at its margins to the frame. The frame, handle and lattice wotk, may be moulded in one piece with reinforcement by a wire loop 1 having two parallel projections extending into the handle. The moulded portion 5 between the wire in the handle is thinner than the reinforced marginal parts but a portion 6 at the base of the handle and a part 7 between the handle and the latticework are of the same thickness. In a modification (not shown), the one piece moulded frame and lattice-work is reinforced by a wire having two parallel projections for attachment of a handle.

[Class 40 (v)] The output electrode of one valve of an amplifier is coupled to the input electrode of the next valve by a tuned circuit comprising a variable inductor 14 having two shunt capaci- - tive arms, the first comprising a capacitor 18 connecting a high potential point of the inductor with the output electrode 12, and in series with the output capacitance 19 of the valve, and the second comprising a capacitor 21 connecting the high potential point of the inductor with the input electrode 13 and in series with the input capacitance 20, the value of the capacitors being such that the reduction of the L/C ratio of the circuit caused by the input and output capacitances is reduced. The circuit diagram shows the H.F. and mixer stages of a receiver, the two tuned circuits of which are permeability tuned. Capacitors 18 and 21 are of the same order as the output and input capacitances, respectively, of the valves.

Abstract: 1,001,866. Fuel injection pumps; regulating. C. A. V. Ltd. April 4, 1962 [April 7, 1961], No. 12520/61. Heading F1A and F1B. The maximum delivery stroke limiting means 21, Fig. 1, of a pump comprising plungers 13 actuated by a cam 15 is adjusted in accordance with the density and/or viscosity of the fuel by a piston 23, Fig. 2, operated by fluid pressure which is controlled by a valve 33 actuated by a float 34 in a chamber 35 to which fuel is continuously supplied. In an injection pump having a feed pump 8, Fig. 1, and a rotary block 12 carrying radial pistons 13 operated by the cam 15 through follower rollers 14, the stroke limiting stop is formed by a pair of rings 21 which have recesses co-operating with the recesses in cam 15 so that angular adjustment of the rings varies the maximum outward movement of the pistons 13. The rings 21 are adjusted by the spring-loaded piston 23, Fig. 2, subjected to the feed pressure of pump 8 through a passage 28. When petrol is used the float 34 sinks to close valve 33 and when diesel oil is used it floats to open valve 33, whereupon pressure is applied to the piston to adjust the stops 21. In a modification, the fuel is supplied to chamber 35 through a restricted passage and escapes therefrom through a wider passage so that when petrol is used the fuel level in chamber 35 is high and the float closes valve 33 whilst when diesel oil is used the fuel escapes from chamber 35 at a faster rate than it enters so that the fuel level therein is low and the float opens valve 33.

Title: Improvements in on-load changers for regulating transformers
Inventor: HENRIKSEN EGIL
IPC: B23K9/028
Filed: 1971-04-30
Abstract: 1300860 Transformers NATIONAL INDUSTRI AS 30 April 1971 [30 April 1970] 12562/71 Heading HIT An on-load top changer for a regulating transformer comprises a power transfer switch having fixed main contacts H1, H2 and respective auxiliary contacts M1, M2 and a thyristor circuit connected between each main contact and its auxiliary which is capable of conducting in either direction between the two. Resistors R3, R4 in parallel with fuses S1, S2 are connected in series with the thyristor circuits such that, if the circuits do simultaneously conduct resulting in large circulating currents being developed, the fuses S1 and S2 will blow connecting the resistors R3 and R4 in circuit such that they act as conventional transfer resistors. Supply units P1 and P2 are connected between the contacts and a control unit St for the purpose of supplying ignition currents to the thyristors Q1 and Q2 or Q3 and Q4 at the required stages of the top changing operation. This operation, described in detail in the Specification, is such that the thyristor circuits connected across the respective contacts do not simultaneously conduct, therefore preventing circulating alternating currents from being set up when both the contacts M1 and M2 are closed. Other suitable electronic devices may be used in place of the thyristors.

Divided out of 455,436. [Classes 51 (i) and 51 (ii)] A furnace chamber is heated externally by the partial combustion of charcoal in a producer, and internally by the combustion with air of the gas produced, the supply of air being controlled to give the desired neutral or reducing atmosphere for the goods under treatment. In the construction shown in Fig. 2, gas from the producer A passes through the perforated collector C to the combustion chamber C<1>, where it meets a supply of secondary air from the pipe c, the products of combustion passing through a work chamber D, and thence either directly, or through a second work chamber D<1>, to the exhaust flue D<2>. The fuel may be'dried in the hopper B<1> by the heat of the waste gases, or in the container B by the heat of the producer, the gas being allowed to escape during the drying period through a valve in the air-tight cover b. The secondary air may be heated by passing the supply pipe c through the exhaust flue and both primary and secondary air supplies may be dried if an atmosphere free from hydrogen or water vapour is desired. In a modification, Figs. 4-6 (not shown), two producers are arranged beneath the floor of the firing-zone of a tunnel furnace, into which the gas passes through side ports where it meets the secondary air supply. In another modification, Fig. 7, in which the producer is at one side of the furnace N, bottom heat is supplied by the hot gas in the flues n, and top heat by the combustion of this gas with air supplied by the pipe n<2>. The constitution of the furnace atmosphere may be automatically controlled as described in Specification 455,436.
