Patent GB-652609-A (GB)
Title: Lamp sealing apparatus
IPC: H01J9/40
Filed: 1947-08-07
Abstract: 652,609. Making electric lamps; gas burners. SYLVANIA ELECTRIC PRODUCTS, Inc. Aug. 7, 1947, No. 21694. Convention date, June 28, 1940. [Classes 39(ii) and 75(i)] In apparatus for sealing off a vertically arranged exhaust tube of an electric lamp having means to impart a reciprocating horizontal stroke to a pair of centrally notched semi-conical burner shields and to a pair of sealing-off burners which direct a flame into the shields, variations in the location of the exhaust tube in the direction of the stroke are accommodated by automatic variation of the length of the stroke, e.g. by means of a lost-motion connection and a spring centring means. As applied to an exhausting machine wherein the exhaust tube 2 of an electric discharge lamp is pushed upwardly into a rubber connection 23, the lamp being indexed through suitable exhausting stages to the sealing station shown, a pair of spring- closed splayed end jaws 4 are provided, each carrying a burner 16 or 17 and a semiconical shield 18 or 19, and pivoted at 57 to a plate 13 mounted on a pin 29 in a saddle 28 integral with a member 59 rotatable on a stud 5 projecting from a slide 45. Cam actuation of a rod 40, connected by a link 44 and a spring-loaded slotted lever 43 to the slide, projects the whole assembly towards the exhaust tube 2, an upper slotted baffle plate 3 engaging the tube 2 and serving to adjust the plate 13 about the stud 5, while horizontal slots engaged by the pin 29 in the saddle 28 allow the notches 8 in the shields to adjust themselves in the direction of projection, on to the tube 2; a fork 25 on the slide 45 serves with the spring 26 to steady the lamp body. Cam actuation of a rod 41 then lowers the assembly (the slot in the lever 43 now being vertical), so that the shields 18, 19 enter the lamp stem flare, slight rotation of the plate 13 about the pin 29 being allowed within the limits of stops 24, 54. When the flames from the burners 16, 17 have softened the tube 2, cam actuation of the rod 41 lowers the assembly further so that the jaws 4 press the lamp down to seal and sever the tube 2 within the flared lamp stem, the grip of the chuck 27 being not so strong as to prevent this. The rod 41 is then moved upwards slightly so that the flames from the burners 16, 17 may anneal the tip of the tube 2. Further cam actuation of the rods 40, 41 returns the assembly to starting position with the stud 12 against the stop spring 51, and the machine is indexed.

Title: Improvements in and relating to the manufacture of razor blade strip
IPC: C23C8/22
Filed: 1945-08-27
Abstract: In a method of manufacturing high-carbon steel strip, low-carbon steel is rolled to strip form and then gas-carburised to the desired high-carbon content.  The invention is desdribed as applied to the manufacture of strip for the production of razor-blades.  Mild or low-carbon steel having a carbon content of the order of 0.15 per cent, and preferably fully de-oxidised is rolled down to a thickness of 0.005 inch and width of about six inches.  It is then cut into strips 0.882 inches wide and passed through a furnace through which a carburising gas is passed continuously in the opposite direction and carburisation is continued until the difference in carbon content of the metal at the surface and at the centre of the strip is less than 0.3 per cent if there is little or no chromium present or up to 0.6 per cent if chromium is present up to 20 per cent.  If desired, the middle portion of the strip may be protected from the carburisation by covering it with a coating of copper.  The carburising takes from two to fifteen minutes at a temperature of from 900 DEG  C. to 1000 DEG  C., after which the strip is rapidly cooled to below the transformation temperature of about 700 DEG  C. in a controlled atmosphere.  The strip may then be blanked, hardened, tempered, honed and lacquered and cut up into blades.

Title: Method and means for determining absolute direction of propagation of electromagnetic waves
IPC: G01S3/14
Filed: 1938-09-13
Abstract: 519,462. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. Sept. 13, 1938, No. 21997/39. Convention date, Sept. 17, 1937. Divided out of 509,731. [Class 40 (v)] The absolute direction of propagation of a wireless wave is determined (a) by measuring the angle between the electric and magnetic fields in a given plane, and (b) by finding the ratio of the strengths of these fields in a plane at rightangles to the first plane. From these quantities; the absolute direction can be calculated, free from night effect " or " aeroplane error." The electrostatic pick-up from the two horizontal dipole aerials 21, 22, set at right-angles to each other, is applied to the two pairs of deflecting plates of a cathode-ray tube 45, whilst the electromagnetic pick-up from the two stationary and angularly-disposed frame aerials 10, 11 is similarly and alternately applied to the same deflecting plates, all under the control of switchover contacts 46 - - - 49. The trace on the screen of the tube gives the required angle of intersection. The ratio of the field-strengths of the magnetic and electrostatic fields is separately measured by a meter 50, which is fed from the vertical dipole 20 and horizontal frame 12.

Abstract: 1,132,906. Branch fittings. CABOT CORP. 18 May, 1966 [20 May, 1965], No. 22067/66. Heading F2G. [Also in Division B5] Compositions comprising a cured polymeric material and between 20 parts and 500 parts per 100 parts by weight of the material of an electrically conductive filler are welded by localized heating of the surfaces to be welded to above the softening temperatures thereof, interposing between said surfaces an adhesive composition comprising a thermally activatable curing agent, bringing said surfaces into direct proximity with each other with only the adhesive composition therebetween, and flow sufficient electric current through the cured compositions and the adhesive to activate the adhesive. The cured or "cross-linked" polymeric composition may be a cured polymer or copolymer of a lower α-mono-olefinic hydrocarbon, e.g. polyethylene, polypropylene, ethylene/butene-1 copolymers, ethylene/propylene copolymers and mixtures thereof. The filler material is preferably a carbon black such as thermal black, acetylene black, oil furnace black, gas furnace black, channel black or a mixture thereof. Alternatively, the filler material may be a finely-divided or powdered metal or-metal alloy, such as copper, iron, nickel, chrome/nickel, aluminium or iron/nickel. Curing may be effected by gamma or ultra-violet irradiation of the composition or by thermal activation of a suitable curing agent, e.g. an organic peroxide, dispersed therein. The adhesive comprises a curing agent which may be an organic peroxide, such as di-α-cumyl peroxide, tert.-butyl-α-cumyl peroxide, tert.-butyltriphenyl methyl peroxide, decanoyl peroxide, caprylyl peroxide, or benzoyl peroxide, or may be a quinone oxime or a quinone oxime derivative. Preferably, the adhesive interlayer comprises an essentially uncured polymer containing at least 20 parts, e.g. 50-120 parts, per 100 parts by weight of the polymer of an electrically conductive filler and between 0À5 and 10 parts per 100 parts of a curing agent of one of the types specified above. Preferably, a curing agent is chosen which has an active curing temperature range at least slightly above the softening temperature of the adhesive composition. The adhesive composition may be applied to the surfaces in a finely granular or powdered form, as a solution or as a sheet or film. Prior to application of the adhesive the surfaces are heated above the softening temperature thereof to a depth of between <SP>1</SP>/ 16  inch and ¢ inch by flame impingement or by a hot iron contoured to the shape of the surfaces. In the embodiment shown, to form a "T" pipe joint, surfaces 3, 4 of pipe portions 1, 2 to be joined are heated, an adhesive film 5 is placed between the surfaces 3, 4 and the portions 1, 2 are brought together. An air powered ram is lowered on to a surface 14 and an electric current is passed between the electrodes 6, 9 to earth to effect the welding. Thermocouples 10, 11, 12, 13 are inserted into the portions 1, 2 to measure the temperatures thereof during welding.

Title: Method and apparatus for fabricating a screw and captive washer assembly
IPC: F16B39/26
Filed: 1975-05-22
Abstract: 1464191 Rolling screw threads ILLINOIS TOOL WORKS Inc 22 May 1975 [30 May 1974] 22224/75 Heading B3M A washer is retained on a screw by placing the washer on the shank of an unthreaded screw blank between the blank ends, swaging the shank between the washer and the head to a required form, moving the washer towards the head, and then swaging the shank on the side of the washer away from the head to form a screw thread of crest diameter greater than the diameter of the washer aperture. Fig. 1 shows one of a pair of dies used to roll the screw thread on a blank 10 shown at four successive positions. At A, the blank is about to enter the dies, an axially compressible washer 30 entering a slot 34 and being supported on a ledge 36. Upper parts 32 of a first section of each die from a screw thread on portion 18 of the blank, the crest diameter being less than the diameter of the washer aperture, so that as the blank progresses from B to C, the washer rides up the ramp 42 to seat against the head of the blank. The thread on portion 20 of the blank is initially rolled by the lower parts 38 of the first section, and subsequently by portion 40, which extends the thread to merge with that on portion 18. In this way, when the screw is threaded into a tapped hole (e.g. one threaded by a thread cutting formation on the screw), all parts of the shank can enter the hole, and the washer can be fully compressed. Fig. 5 shows a modified screw in which a portion 26 of lesser diameter than the initial blank has been rolled, and a shoulder 28 formed over which the washer has to be sprung in its travel up the shank. In a modified version of the dies, the slot 34 has no level portion but is inclined to form a ramp from the entry end of the die, Fig. 6 (not shown), and in another modification, Fig. 7, the slot 34b is cut back at the entry end of one die to assist entry of the washer, the ramp 42b is curved, each die is relieved in a transition area 70 so that rolling commences there more gradually, and the upper face 72 of the slot 34b extends parallel to the die grooves.

Class 120(1) Cams at the ends of faller driving screws in hackling frames and intersecting gill boxes are shaped to give smooth acceleration and deceleration to the vertical movements of the gill bars by merging tangentially into the screw spindles against which curved cam follower surfaces of the gill bars bear. Cams on working and return screws work in association to maintain the gill bars under control throughout the vertical movements. When a gill bar comes to the end of a horizontal stroke. the bar end 3 moves from contact with the screw spindle 1<SP>1</SP> into contact with the edge of the cam I and, at the same time, the edge of the cam II moves into contact with the under side of the end 3 and descends under control into contact with the screw spindle 2<SP>1</SP>. The cams I, II may be formed with laterally inset surfaces at 4 to facilitate changes from horizontal to vertical motion without shock. In order that the gill bars may readily be removed from the machine and replaced, one of the rails along which the gill bars slide during their working stroke may be movable.

Title: Improvements in apparatus for applying closures to containers
IPC: B67B3/14
Filed: 1947-08-13
Abstract: 649,328. Bottling. CROWN CORK & SEAL CO., Inc. Aug. 13, No. 22537. Convention date, Jan. 24, 1947. [Class 125(ii)] In an apparatus for applying closures to containers, the intermittent relative approach of a capping head and successive containers results in closure caps being detached from the magazine 80 and advanced to the applying position beneath a capbottom of a stack in a ping throat 34 by a slide 129 reciprocating in a slideway formed in a platform 99 having a rear surface 132 which in the advanced position receives and supports a detached closure. Figs 3 and 4 show the apparatus in the rest position in which the stack is supported by portions 68 of magazine fingers which in swinging counterclockwise to the position shown in Fig. 4, detached the lowermost cap with a wedging action so that it was deposited on the rear surface of the slide. If a cap 20, of the type described in Specification 637,745, is assumed to be supported through its flanges 23 on ledges 135, 136 formed by spaced-apart forward extensions 133, 134 of the slide and centred relative to the capping throat by a wall 139 and slide advance limit stops 141, 142 with its top surface spaced below a presser foot 35 a distance slightly greater than the thickness of the stops, then movement of a bottle into engagement with the cap 20 will lift the latter against the pressure foot 35 so that its flange will be above the stops. As the rise of the bottle continues, a throat carrier 31 is lifted, thereby swinging bell crank levers 87 and 88 to retract the slide and also, through a link 150, swing a ring segment 74 thus swivelling the magazine fingers so that the portions 68 move from the supporting position of the stack which drops thereon. As the slide retraction continues, the cap on the slide surface 132 is held against movement therewith by the full-depth portion 58 of a sleeve 46 and as the slide moves to its outer limit the detached cap falls on to the forward supporting ledges of the slide. The upward movement of the throat carrier is arrested by abutment with a bracket 25, the throat 34 is projected somewhat downwardly against the action of a spring 36 and thereafter the presser foot spring yields and the cap is applied. Then the bottle is lowered thus permitting the throat carrier to lower and the parts to resume the rest position.
