Title: Improvements in and relating to electric lighters for cigars and the like
IPC: F23Q7/00
Filed: 1921-04-26
Abstract: 162,296. Zecchini, A., (Assignee of Panza, I.). April 26, 1920, [Convention date]. Lighting cigars and the like by electric devices.- In an electric igniter for cigars &c., current is conveyed to a socket member adapted to receive a removable plug and provided with contacts for conveying the current to a resistance wire located in the bottom of the plug, a switch being provided at the top of the plug. The socket 7 is carried on a plate 2 screwed to the wall and has spring- plungers 5, 6 connected through contacts 5<1>, 6<1> to the source of current supply. The body 7 of the removable plug is screwed at the bottom to take a cap 10 enclosing a block of refractory material 9 in which the resistance wire 11 is located. The resistance wire is connected at one end to a rod 13 and at the other end to a metal ring 12 which contacts with the metal body of the plug which, when in position, makes contact with the plunger 6. The plunger 5 contacts with a metal ring 14 insulated from the body of the plug by bushings 14<1> but connected by a brush 19 to a rod 15 adapted to be depressed against a spring 17 by a push-button 16 so as to complete the circuit by contact with the rod 13. In operation, when the resistance wire 11 has been rendered incandescent by pressing the button 16, the plug is removed by means of its head 8 for lighting a cigar. In order to prevent short-circuit in removing the plug, the arrangement is such that before the plunger 5 contacts with the metal part 7 of the plug, the plunger 6 has already cleared this part.

Title: Production of shaped articles from thermosetting or thermoplastic material
IPC: B29B13/00
Filed: 1946-04-18
Abstract: 611,422. Moulding plastic material. COMMUNICATIONS PATENTS, Ltd., and STEPHENS, R. L. April 18, 1946, No. 12102. [Class 87(ii)] Uncured thermosetting material in rod, bar or strip form is moulded by feeding a length 8 of such stock material to a high frequency dielectric heater 10, 11 by a reciprocating device indicated at 9, feeding the heated terminal portion forward to overhang the cavity 12 of a heated mould 3, 4 and then bringing down the male part or plunger 3 of the mould to shear off the preheated portion of the material and mould it under heat and pressure. The remainder of the stock is withdrawn, after shearing, from the immediate vicinity of the mould and a fresh terminal. portion heated for the next shearing and moulding operation. Alternatively the sheared-off portion may be forced into a transfer cavity and from these through a small orifice to the mould. The method may be performed with a vertical movement of the material and longitudinal movement of the plunger instead of vice-versa as shown. The various operations may be carried out automatically in timed sequence. The stock material in rod &c. form may be formed immediately before the processing above described e.g. by an extrusion machine delivering on to the table 6 from which the material is fed to the heater and mould. The extruded rod &c. may be cooled if the material is in a sensitive chemical condition, while waiting to be fed to the heater and mould. The Provisional Specification states that thermoplastic materials, e.g. polyvinyl chloride and polyethylene, may be moulded by the same method, the moulding tool then being cooled. It is also stated that the moulding may be by extrusion or a combination of extrusion and compression moulding and that moulding may be carried out in two steps with or without intermediate heating.

Title: Improvements in diversity receiving systems
IPC: H04B7/10
Filed: 1942-08-28
Abstract: 557,648. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 28, 1942, No. 12174. Convention date, Aug. 30, 1941. [Class 40 (v)] A diversity reception system including at least two receiving channels and a common output circuit, is provided both with a carrier A.V.C. system to reduce the gain in both or all channels to a level determined by the strongest signal being received in any channel, and with a selective fading A.V.C. system which, when selective fading occurs in any channel, renders that channel inoperative for signal reception and prevents its carrier A.V.C. from contributing to the common carrier A.V.C. system. The Figure shows two superheterodyne receiving channels 5, 6 comprising respectively R.F. stages 10, 20, first I.F. stages 12, 22, second I.F. stages 13, 23, detector and A.F. stages 14, 24 feeding a common output stage 16 and loudspeaker 17. Carrier A.V.C. systems 30, 36 are fed from points 29, 35 after the second I.F. stages and the A.V.C. voltages are fed in common to control the first I.F. stages Channel 5 has a selective fading A.V.C. fed from a point 42 before the second I.F. stage and comprises a detector and A.F. stage 40 supplying a D.C. output and an A.F. output to a rectifier stage 43 which supplies a negative voltage dependent on a comparison of these values. When selective fading is present, the A.F. component exceeds the D.C. component and the negative voltage is sufficient. When applied to one or both of the I.F. stages, to block the channel and also to render the carrier A.V.C. 30 inoperative. A similar arrangement 50, 53 is provided for channel 6. Thus a channel in which selective fading is present is blocked even when that channel carries the strongest signal.

Filed: 1951-05-24
Abstract: Hard metal cemented carbide articles are made by casting into a mould a mixture of hard-metal-forming materials with an organic liquid comprising a portion which will polymerize and a portion which will not, polymerizing to an infusible gel, heating to remove the organic material and sintering.  The polymerizable material may comprise unsaturated polyesters of the maleic type, e.g. reaction products of a polyhydric alcohol and maleic acid or anhydride, or a tetrahydrofurfuryl alcohol-modified dipropylene glycol maleate, mixed with a vinyl derivative such as styrene or vinyl acetate and the catalyst, e.g. benzoyl peroxide or ditertiary butyl diperphthalate. Other suitable compositions are described in Specification 633,876. The non-polymerizable liquid, which should amount to 65 to 83 per cent of the whole of the organic liquid, preferably has a high boiling point but should be removable by evaporation below 150 DEG C. and miscible with the other materials, e.g. diethylene glycol mono-ethyl ether acetate, ethylene glycol mono-ethyl or methyl ether acetate, glycol diacetate with or without the admixture of diethylene glycol. Suitable casting mixtures have the following percentages by volume: .Hard metal carbide powdered. .materials .. .. ...38-41.5 .Polymerizable ingredients ...10-20 .Non-polymerizable liquid ...48-41-5 .Polymerization catalyst ...0.1-0.75 Polymerization is accelerated by heating to 80 DEG  C.  After removal from the mould the article is dried at 45-150 DEG C. for 2-5 days, and then heated in hydrogen at 450-800 DEG  C. for 1 hour to expel the polymer and then at 1350-1500 DEG C. for 1-2 hours to sinter.

Abstract: 185,458. Terrey, A. May 3, 1921. Driving printing-machines : rotary machines. -In rotary machines in which worm gearing is employed for driving the impression, plate, or inking cylinders, or other parts, the driving- worms are constructed of such an angle and pitch to permit of their being rotated by the wormwheels or spiral toothed or helical wheels with which they engage. On arresting the movement of the driving-element, the driven part is not suddenly arrested by the worm, but stops gradually, a resistance being offered through the worm, which thus acts as a brake to check the movement. As shown, worms f, g on a driven shaft e drive worm-wheels f<1>, g<1> on the spindles of an impression cylinder a, and plate cylinders b respectively. The wheel g<1> engages a worm i on a shaft h, which drives the shaft of an inking-roll c by means of a worm j and worm-wheel k. The shaft h may be the driven shaft.

A bi-prism focusing arrangement for cameras comprises four wedge prisms 10, 11, 12, 13, whose image intersection lines 19, 20, 21, 22 (i.e. the lines which divide the image of the subject being viewed) meet in a central point 23 Figs.4 and 4a, which is lower than the corner points 24, 25 but higher than the corner points 26, 27. Each image intersection line (e.g. lines 19 and 22 for prism 13) is bent at right angles at the point 23. Because this point is at the centre of symmetry, it is possible to use the device for focusing on horizontal and vertical lines or objects sumultaneously. Fig.4a shows the displayed positions F 1  and F 2  (as seen through the device) of a vertical object F 0 , and the displaced positions F 1  and F 2 ' of a horizontal object F o ' . Figs. (not shown) 5, 5a, 5b represent a similar arrangement in which there are differences in height in passing from one prism to the next. Figs. 6 and 6a show an arrangement having two wedge prisms only, 40 and 41, the image intersection line 42 being bent twice at points outside the centre of symmetry 43.

Filed: 1916-09-07
Abstract: 108,148. Dalton, W. July 18, 1916, [Convention date]. Projectile fuses.-Relates to percussion fuses provided with a centrifugal arming-device, and consists mainly in providing means whereby the centrifugal device is disengaged from the percussion pellet by the action of an inertia member at the instant of discharge, and whereby the fuse cannot remain armed unless the projectile rotates at a speed which is above a certain minimum. In the fuse shown, the pellet 7, which carries a percussion cap and has a powder core 7<e>, is normally locked by one or more arms 10 bearing upon a flange 7<S>, the hooked forward ends of the arms engaging in slots in an inertia sleeve 9 surrounding the pellet. When the projectile is discharged, the sleeve 9 sets back momentarily and positively moves the members 10 out of engagement with the pellet. They remain in this position, in which the fuse is armed, so long as the projectile rotates at or above a predetermined speed, but otherwise the sleeve 9, pushed forward by its spring 12, returns the arms to the locking position. The object of this is that the fuse is not rendered unsafe by accidental rotation, as for example by the projectile being rolled. In a modification the inertia pellet carries the firing- pin, and the percussion cap is fixed.
