Abstract: 1,113,483. Surface condensers. SOCIETE EUROPEENE D'EQUIPEMENT "EUREQUIP". 28 May, 1965 [28 May, 1964], No. 22895/65. Heading F4S. A turbo-alternator is mounted on a supporting block which incorporates a condenser for low pressure steam from the turbine, the block comprising a metal or plastics lined chamber formed from a series of pre-stressed or poststressed or reinforced concrete parallel frames 17 interconnected by cross members 15, the chamber having an open top and having the sides closed by partitions 18 and the ends closed by tube plates 13 between which extend straight or undulating condensing tubes 23, 24, additionally supported by intermediate plates 36, 37. The top of the chamber is sealed by means of a fluid tight joint 27 to the exhaust of the low pressure stage 25 of the turbine. The cooling water is supplied to and withdrawn from the condenser through integral concrete pipes 19, 22 opening into water boxes 12 having doors 31, the water passing through the tubes either in a single pass (Fig. 2, not shown) or a double pass (Fig. 5) wherein the tube plate may be in two halves 13a, 13b divided by a partition 18<SP>1</SP>. The steam condensate is collected in a tank 28 in the base of the condenser before being withdrawn through a pipe 30. The lining 33 which may be welded in the case of metal to T-pieces 35 embedded in the concrete, is slightly corrugated (Fig. 9, not shown) to allow for expansion, whilst to permit expansion of the intermediate plates 36, 37, also attached to the T-pieces, an expansion absorbing joint (50) (Fig. 7a, not shown) is interposed between the plate and the T-pipce. To accommodate expansion of the tubes 23, 24, the tube plates 13 are attached to the chamber (Fig. 11) by means of a sole plate 42 bearing on a slide 44, the fluid seal being maintained by a joint 46 and a flexible membrane 43. The axis of the chamber may either be parallel or transverse to that of the turbo-alternator group, whilst the whole assembly may be carried by supports 14 extending deep into the ground or any other foundation device appropriate to the nature of the soil.

Title: Improvements in electrical make-and-break contacts and method of making same
IPC: H01H1/021
Filed: 1932-08-16
Abstract: In the manufacture of metallic make-and-break contacts made of tungsten or molybdenum and adapted for ignition systems in motor vehicles, the material is treated so as to increase the size of the surface granules or to reduce the amount of amorphous material between the granules, such treatment consisting in heating the tungsten &c., with a compound of silicon, such as sodium silicate, which is reduced to oxide of silicon by the heat.  The metal is then mechanically worked to form a body having an interlocked grain structure.  In a preferred process a mixture of oxide of tungsten with 0.5 per cent of sodium silicate is fired in a silica crucible for about an hour at a temperature of 1100 DEG  C. and then re-heated for a longer period in a reducing atmosphere of hydrogen at a temperature increasing from about 400 DEG  C. to 900 DEG  C.  The mixture is removed from the reduction furnace and, after sieving, pressed into slugs under considerable pressure; the slugs are then baked in a non-oxidizing atmosphere for 15 minutes at about 1250 DEG C. and finally heated electrically in an atmosphere of hydrogen or equivalent to a temperature of 3000-3200 DEG  C., care being exercised to avoid equiaxing of the granules but to maintain the interlocked structure, while at the same time a considerable proportion of the silicon is volatilized.  After rapid cooling, the slugs are hot-swaged into rods, and the process of electrical heating to a temperature of about 2400 DEG  C. in hydrogen repeated.

Title: Improvements in or relating to acoustic devices such as loud speakers
IPC: H04R7/00
Filed: 1930-07-31
Abstract: 360,030. Loud-speakers. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Wegel, R. L. ; 30, 5th Avenue, New York, U.S.A.) July -31, 1930, No. 23160. Convention date, Aug. 17, 1929. [Class 40 (iv).] An acoustic device, such as a loud-speaker, comprises a diaphragm 10 composed of a plurality of highly stretched parallel wires 15 connected to one or more actuating devices. The wires, which may be of rectangular or square cross section, may be arranged so close together that leakage of air between them is reduced to a negligible amount or the diaphragm may be rendered continuous by a membrane consisting of a number of thin paper or fabric strips 28 interlaced with the wires. The diaphragm is mounted on a frame consisting of uprights 1 having horizontal channelled iron members 2, 3 embedded therein as shown in Fig. 2, the frame being supported by a number of channelled iron members 11 secured by angle plates 27 and bolts 9, 12 to the bracing upright 6 fixed to the cross members 2, 3. A turn-buckle 7 is provided between the uprights 1, 6. Each of the wires 15 has its lower end secured over a hook 16 in the member 3 and its upper end is then twisted about the looped portion of a corresponding hook 13 in member 2, the tension of each wire being adjusted by a nut 14. All the wires are preferably tensioned to the same degree and to such an extent that they will transmit acoustic vibrations impressed thereon with a velocity considerablv in excess of that of sound in air. The paper 28 is then interlaced with the wires and given a coating of a dilute lacquer solution which, upon drying, causes the elements of the diaphragm to adhere and introduces therein a small amount of lateral tension, the edges of the paper being secured by the lacquer to the frame 1. The paper is of such thickness, together with the coating of lacquer, that the finished diaphragm will propagate acoustic disturbances impressed thereon with a velocity comparable to that of sound waves in air. Further, the diaphragm is preferably of such a length that the energy of the waves is largely dissipated by radiation before the waves reach the supported ends, thus diminishing wave reflection. A rectangular tubular brass member 24 secured across one face of the diaptragm is connected by rods 23 with a number of electromagnetic actuating devices 23 mounted on a support 20 each end of which is fixed to a bracket 18 fastened to an upright 1. Alternatively, the drive may take the form described in Specification 290,239, [Class 40 (iv), Telephones &c.]. A bracket 25 secured to the upright 6 and a base member 11 gives the required rigidity to the frame structure.

Title: Improvements in walking toys
IPC: A63H15/02
Filed: 1947-07-18
Abstract: 645,863. Walking toys; race games. NICHOLLS, K. H. July 18, 1947, No. 23209/46. [Classes 132 (ii) and 132 (iii)] A walking toy figure comprises a body portion, a fixed limb member extending forwardly of the body portion, a freely mounted limb member pivotally attached to the body portion in such a position that when the figure is caused to rock on an inclined surface it progresses down it by rocking alternately on the two limb members, the freely mounted limb member swinging forwardly as the figure rocks forwardly on the fixed limb member, and the fixed limb member swinging forwardly as the figure rocks rearwardly on the freely mounted limb member, and means for interfering with the free oscillation of the figure, thus influencing the periodicity of the oscillation. As shown, Figs. 1 and 2, a grotesque figure is constructed from layers of wood, the central layer forming the fixed limb member 12 and the head portion 13, two outer layers 14 pegged to the central layer forming the body portion. The central layer is shaped to leave a recess in which a freely mounted limb member 18 is pivoted. Arm members 21 may also be provided. The limb members 12 and 18 are provided with base portions 22 and 23 extending transversely, the operative surfaces of these base portions being curved. The surface of base 22 may be covered with rubber 24 to prevent sliding. The fixed limb member is provided with an adjustable stop member 25 to interfere with the periodicity of the oscillation. A plurality of figures may be used in race games as shown in Figs. 6 and 8, in which the toy is shaped to simulate a horse and jockey 51, the fixed limb member 31 being formed with the forelegs and the freely mounted limb member 32 formed with the back legs. The body of the jockey 42 may be formed as an extension on the freely mounted limb member so that it oscillates relatively to the horse portion simulating the natural movements of a jockey. The figures are arranged for progression along separate tracks 52 provided with side guides and are started simultaneously by spring urged starting members 54. Quick release cams 56 mounted on a common shaft 58 bear against a projection 57 on the starting member. Rotation of the starting knob 59 in a clockwise direction releases the starting members causing the figures to rock. The finishing barrier 72 carries electric switches 74, one to each track, and thus serves by illumination of a lamp to indicate the winning figure. The operative surface of the track 52 may be provided with a slidable insert 77 coplanar with the track and formed with a series of indents 78 arranged irregularly along it. As the stop member or projection 79 registers with the indents the rate of progress is varied. The inserts 77 may be manually adjusted between fixed limits by means of knobs 81 thus introducing an element of skill into the game. Specification 645,927 is referred to.
