IPC: H02J3/42
Filed: 1950-08-21
Abstract: 692,939. Synchronizing. ELECTRIC CONSTRUCTION CO., Ltd. Aug. 15, 1951 [Aug. 21, 1950], No. 20688/50. Class 38 (iv). An automatic paralleling system for A.C. systems 1, 2 comprises a paralleling switch 3, 4 controlled by the contact 6 of a relay having a winding 7 shunted by a condenser 15 and energized over rectifier 14 by the difference between nominally equal voltages 12, 13 derived respectively from the two systems. When the beat frequency between the systems is relatively high, condenser 15 maintains the relay energized and so prevents energization of the switch coil 4, but as the beat frequency is reduced the cyclic voltage variations (at beat frequency) of the condenser become progressively greater and upon the beat frequency falling to a predetermined value, determined by a variable resistor 16, the condenser voltage falls to a value insufficient to maintain the relay operated. The paralleling switch is thus caused to close at a point in the heat cycle favourable for synchronizing. Specification 692,989 is referred to.

Title: Machine for making paper and like cups or trays for holding or wrapping confectionery
IPC: B31B45/00
Filed: 1920-07-12
Abstract: 169,840. Henderson, C. July 12, 1920. Cupping.-Relates to machines for making crimped paper cups or trays for holding confectionery of the type in which a corrugated inverted conical disc such as 12. Fig. 3, is mounted loosely on the end of a reciprocating rod 13 carrying a corrugated plunger 10, with a spring 20, Fig. 1, between the rod and the die. The die 12 is thereby caused to descend and force a number of blanks carried in apertures 8 in a revolving table 6 on to a counterpart die 4, after which the plunger 10 descends relatively to the die 12 and forces the blanks through a cylindrical part 5 of the counterpart 4. The invention consists in forming the apertures 8 by stepped rings so that different sizes of dies and counterparts may be used. The rod 13 is reciprocated by a crank 17 rotated by a spur-wheel 17<a> from one of two pulleys 18, 19. The die 12 is slidably connected to the rod 13 by a keyway 15 and screw 14 so as to be easily exchangeable, and the plunger 10 slides inside the die 12 and enters a recess in the end of the rod 13. The counterpart 4 is fitted in a stepped aperture 3 in the base 2 of the machine. A number of stepped rings 8 are fitted in apertures in the table 6 which is given a step-by-step rotation by means of bevel wheels 22, 23 operated by a. ratchet wheel 24 from a pawl oscillated by a crank 28 and connecting-rod 27. The finished cups are delivered into a drawer 21. In place of the crank 17, pressure may be imparted to the rod 13 by a screw and bandwheel.
Patent GB-209068-A (GB)
Abstract: 209,068. Brandenberger, H. Dec. 23, 1922, [Convention date]. Gear-cutting. - In shaping bevel-wheels with curved teeth by a machine wherein the longitudinal tooth-form is produced by reciprocating the cutters in a straight line and rotating the blank continuously on its axis, the blank and the imaginary crown gear of which the cutters form one tooth, are rolled together to generate the tooth profile, and the movement of the cutting tools round their driving-mechanism is compensated bv an additional rotary movement of the cutter head or of the work, or by modification of the cutter reciprocating-mechanism. The driving- shaft 2 drives through worm-gearing 4 a crankshaft 6 the crank-pin 7 of which is connected to a cross-head 9 which operates the tool-rams 10, 10<1> provided with slides and holders for the cutters 14, 14'. A bevel-wheel 15 on the shaft 2 drives through bevel and spur gearing a wheel 20 which through a differential gear drives a shaft 23 connected through further gearing to drive a worm wheel 36 on the blank spindle 37 to impart continuous rotation to the blank. The rolling generating movement is imparted to the cutter-head 45 through worm gearing 38 driven through spur gearing 41 from the shaft 2. Corresponding rolling movement is superposed on the continuous rotation of the blank by means of worm gearing 50 driven from the worm 38 through change gears 47 and actuating the planet-wheel casing 51 of the differential gear. In this form the compensating movement for the rotation of the cutter-head about the crank shaft 6 is imparted to the blank and is obtained by making the necessary correction in calculating the change gears 47. In a modification, the correction may be imparted to the rotation of the cutter-head 45. In a further modification, the cutter reciprocating-mechanism is arranged as shown in Fig. 5. The wheel d carrying the crank-pin from which the tools are driven is mounted on the cutter-head the centre of which is at O and is geared through wheels c, b with a driving gear wheel a on a fixed axis A. It is shown that the required compensation for the rotation of the cutter-head about the centre O will be effected provided the gears are chosen so that d<1> = a<1> + b<1> where d<1>, a<1>, b<1> are the pitch circle diameters of the gears d, a, b respectively.

Title: Improvements in or relating to processes and apparatuses for forming absorbent tampons
IPC: A61F13/20
Filed: 1947-08-02
Abstract: 630,104. Shaping-apparatus. RABELL, W. H. Aug. 2, 1947, No. 21127. Convention date, June 2, 1942. [Class 100 (ii)] [Also in Group VI] A process of producing a tampon from flat pieces of sheet-like absorbent material comprises pursing and forcing together the material which surrounds the central portion of the pieces, heating the material and applying pressure directly to portions of the pieces in radial directions inside of the outer surface of the pursed material and pressure directly to the said outer surface to radially indent and compress the marginal portions of the material sufficiently to impart a cylindrical to tapered form thereto and to render the product substantially shape-retaining in character. As shown in Figs. 3, 4 and 7, sheet material pursed up to the shape described in Specification 630,105, [Group VI], is fed to a machine provided with sectors 44 which, upon downward movement of plunger 78, apply radial force to the material. Disposed between adjacent sectors 44 are blades 50 held in slidable members 52 (Fig. 7) having lugs 65 which engage cam slots 64 in a movable cam ring 62. Movement of the cam ring by means of arm 66 causes the blades 50 to engage the sides of the tampon and produce longitudinal folds 31 therein as shown in Fig. 3. The sectors 44 and blades 50 are shaped to form a conical tampon and in a modification the blades may be formed integral with the sectors. In a further modification (Figs. 11, 13, 14, 15), the material is forced through a tube 124, the folds 31 of the tampon being produced by discs 127 extending through slots 126 in the tube. The tampon is then forced through a die 131 having ribs 133 which register with the folds 31 of the tampon. An indentation at the base of the tampon is formed by a member 138 and the conical apex by a member 140: tampons may be made by a continuous process, being moved continuously through the tube 124 and die 131 and being separated from each other by a combined top and bottom-shaping member consisting of a member 140 with a member 138 secured to the top thereof. Heating of the material during forming is effected by an element 137 (Fig. 13) and by a similar element (not shown) in the construction according to Fig. 4.

Abstract: 1,201,732. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. LIMITED. 24 April, 1969 [3 May, 1968], No. 21140/68. Addition to 1,182,820. Heading H1K. A semi-conductor wafer 1, Fig. 5, is provided with a first PN junction 6 parallel to its major faces and a plurality of PN junction portions 7, each of which comprises a central part parallel to the junction 6 and a peripheral part extending towards the major surface 2 of the wafer, and is then cut into discrete elements by an array of sloping-sided criss-cross cuts positioned such that the peripheral portions of the junction portions 7 emerge on the side walls of the separated elements. The cutting method is as disclosed in Specification 1,182,820. In the process illustrated by Fig. 5 the junction portions 7 are formed by selective diffusion or alloying through a mask into the surface 2. The separated elements may comprise diodes, but a three-electrode PNPN device may be formed by alloying Au/Sb to the upper surface 2 to form a further junction, apertures being left in the alloy material to allow control electrodes to be applied to the zones 31. Fig. 3 illustrates an alternative method of forming the junction portions 7. In this case the first treatment on the wafer comprises selective etching of the upper surface to form an array of recesses 4. The entire surface of the wafer is then subjected to a non-selective diffusion or alloying process to define the flat junction 6 and the junction portions 7, which line the recesses 4. A plug 10 of Au/Sb having therethrough a bore 11 is then placed in each recess and alloyed to the wafer to define a third junction 13 adjacent each recess 4. Separation is then carried out as previously and each element is provided with electrodes.

Abstract: 320,693. Holloway, S. P. April 8,1929. Vehicle lamps.-A vehicle lamp comprises an electric lamp bulb L having its filament approximateJy coincident with the proximate focus f<1> of a substantially hemiellipsoidal reflector R, and one or more relatively small concave lenses D disposed between the conjugate focus f<2> and the bulb, the arrangement being such that rays of light from all parts of the filament pass through the lens after a single reflection without traversing the glass of the bulb a second time. The lamp-holder H is shown passing through an aperture at the apex of the reflector, but it may be arranged inclined or at right angles to the longitudinal axis of the reflector. The portion r of the reflector between its apex and latus rectum may approach, in a continuous curve or in steps, nearer to the focus f<1> than the truly elliptical form y, so that rays of light reflected by the portion r pass through the lens in zones nearer to its margin. The centre of the lens may then be obscured or partly obscured as at 0 with negligible loss. Also, the bulb L may be silvered or otherwise obscured as at 0<1>. The transverse section of the retlector may be progressively modified from the top and bottom towards the sides into an elliptical or other form to cause lateral rays of light to pass through the lens nearer to its centre. With such a reflector a narrow helical coil filament could be arranged vertically and the lens more strongly curved in a horizontal plane passing through its centre, without causing undue divergence. The lens could also be of elliptical, rectangular, or other non-circular shape, or it may be circular and provided with a stop or diaphragm of the desired shape. It may have one or both surfaces spherically or cylindrically concave, or it may be of meniscus, toric, of other figured form, and it may be irregularly roughened on one surface to avoid striations. It may be supported by a screen S provided with a window W through which some of the unreflected light can pass to illuminate the foreground.
