Title: Improvements in or relating to electrical transformers
IPC: H01F19/02
Filed: 1922-12-08
Abstract: 208,895. M.-L. Magneto Syndicate, Ltd., and Morris, D. K. Dec. 8, 1922. Transformers. - An intervalve or other transformer for use in radio and other telegraphic and telephonic systems comprises two similar co-axial units B, B<2>, each consisting of primary and secondary turns, the units being separate and face-to-face but having their respective windings electrically connected together. In the form shown, the two units are wound on a cone A built up from H-shaped stampings, the magnetic circuit being completed by ring stampings A<2>. The inner ends B<5> of the primary windings B<3> are connected to the core, the outer ends being brought to terminals C<2>. The inner ends B<7> of the secondary windings B<4> are connected together and the outer ends B<8> of these windings are connected to terminals D<2>. Adjacent layers of the winding are spaced apart by corrugated insulating-material C, Fig. 4, the corrugations extending at rightangles to the conductors. Successive layers are progressively diminished in width, so that the coils comprising each unit are of elliptical form in cross-section. The separation of successive layers may be varied by using curved strips of corrugated paper, which, when pulled straight, are thinner along one edge than the other, the thinner edges being placed at the commencement of each layer, where the inter-layer voltage is nil. The separation of the layers may be increased in the parts of the windings outside the core. The transformer is enclosed in a two-part casing comprising an aluminium or iron casting E and a moulded insulating cap F, the parts of the casing being clamped together, with the core stampings between them, by bolts G<3>, G<4>, which are insulated from the stampings by sleeves G<5>. An outer cover J of metal may be secured to the insulating cap F by a screw J<2>. Auto-transformer connections may be obtained by connecting the inner ends of the secondary windings to the primary terminals, instead of to each other. In a modification, a rectangular core, with a central limb carrying the windings, is employed.

Title: Improvements in fiber boards and process for making same
IPC: D21J1/00
Filed: 1920-12-01
Abstract: 177,834. Muench, C. G. Dec. 1, 1920. Boards. - Fibre boards are made from the bark discarded in the manufacture of wood pulp for paper. The bark together with a large amount of water is brought by a pipe 1 to a separator 2 where a proportion of the water is removed by a pipe 3. The bark and remaining water are passed to a device 5 which chops up the bark into small pieces. It then passes to a disintegrator 7 and a screen 10, additional water being added through a pipe 9. Pieces which do not pass through the screen are returned by a pipe 11 to the disintegrator. A separator 13 removes some of the water leaving a mixture of about 4 per cent material and 96 per cent water which passes through a beater 19 and stock pump 21 to a felting machine. The product of the felting machine is cut into pieces and dried preferably by a moist air drier. The boards may be waterproofed or fire-proofed, or the materials may be so treated while in the felting-machine. The boards are made up a number of classes of fibrous pieces, large pieces about # in. wide and ¢ in. long, fibres 1-32 in. in diameter and ¢ in. to 1 in. long, finer fibres 1-100 in. in diameter and 1 in. to 2 in. long, and small fibres such as are used in paper-making. A proportion of wood pulp fibres up to 35 per cent or 40 per cent may be added to lighten the colour of the board.

Title: Valves for pneumatic anti-skid braking systems
Inventor: PERUGLIA M
IPC: B60T8/00
Filed: 1972-07-20
Abstract: 1345852 Valves; anti-skid braking systems FIAT SpA 20 July 1972 [2 Sept 1971] 33988/72 Headings F2V and F2F A valve for throttling the flow of fluid to a brake during skidding has an inlet 12 connected to an outlet 14 by a flow restrictor 22 and a passageway 18 which is closable by a valve member 24 responsive to the pressure in a control chamber 44 connected to the inlet 12 by a restrictor 50. In use when pneumatic braking pressure is applied to the inlet by a distributer valve the valve member allows unrestricted communication between the inlet and outlet and pressure gradually builds-up in the control chamber 44. When an anti-skid system releases the brakes and reduces outlet pressure, control chamber pressure moves the valve member 24 to close passage 18 so that when the anti-skid system reapplies the brakes the braking pressure in the outlet is built-up again only via restrictor 22, the valve member 24 remaining closed. The valve member can open again only on normal release of the brakes via the distributer valve. The valve member 24 is made of rubber and has a metal backing plate 28 secured thereto and formed with two perpendicularly disposed grooves 30, 32 which allow communication of the control chamber 44 with the inlet when the valve member is fully open against stop surface 46.

Title: Improvements in carburettors whose throttling member is provided with a braking device
Inventor: MENNESSON ANDRE LOUIS
IPC: F02M19/12
Filed: 1958-10-24
Abstract: 843,336. Carburetters. SOLEX. Oct. 24, 1958, No. 34200/58. Class 7(3). In a carburetter whose throttling member is provided with a braking device for slowing down the closing movement of the member when the latter is approaching the slow running position, a mechanism adapted to be displaced between two end-of-travel abutments transmits to the mobile element of the braking device, the closing movements of the throttling member and the conventional regulating device serving to determine the degree of minimum opening of the throttling member is interposed between the throttling member and the mechanism. Fig. 1 shows the parts in the slow running position. The butterfly valve 2 is held shut by its restoring spring (not shown). The degree by which the butterfly valve is shut is determined by the contact of the screw 12 with the plate 13 and the arm 10b with the abutment 24. When the butterfly valve control is released, the valve being open, the valve is repelled towards its slow running position by its restoring spring moving freely until the screw 12 comes into contact with the plate 13 of the lever 10. Thereafter the piston 7 is driven downwardly and the closing movement of the throttle is braked since petrol can flow out from beneath the piston only through the annular space between the piston and the inner wall of the cylinder 6. The pipe 1, chamber 4, cylinder 6 and duct 17 can all be cast together and the cover 5 and masking cover 18 can also be cast in one piece. The lever may comprise two separate arms 10a and 10b keyed on a shaft 11 or may be made in one piece.
