Title: Method of and means for panel beating
IPC: B21D1/12
Filed: 1955-10-14
Abstract: 840,881. Restoring shape of door panels. DOBSON, J. D., and OAKES, W. Oct. 9, 1956 [Oct. 14, 1955; Feb. 22, 1956], Nos. 29357/55 and 5547/56. Class 83 (4). A panel beater's anvil for use inside hollow structures such as door panels has a detachable shaft-like handle 6, Fig. 3, which can be inserted through a small hole in the wall opposite the point to be deformed and is then coupled to an anvil head 8 inserted through a larger opening elsewhere and is already present or cut for the purpose. The handle 6 has a ball-shaped head 7 insertable into a socket 10 and yieldably locked in position by a " U "-shaped spring clip 11. Alternative handles 5 may be curved or cranked and the ends may be screw-threaded for the attachment of an extension-piece (not shown) but during normal use the thread is protected by a screw-cap 18 having a shield 17 for the operator's hand when hammering. In a modification the handle may be screwthreaded and forced towards the work against pressure on a thrust-plate 20, Fig. 4, resting inside the opposite wall 1 of the panel. The thrust-plate 20 has a spherical seat which is engaged by a part-spherical nut 21 through which the shaft is screwed by a hand wheel 23. The nut 21 may be split for quick release and the assembly held together by a coil-spring 22.
Patent GB-1550847-A (GB)
Title: Knitting machine
IPC: D04B7/00
Filed: 1976-07-14
Abstract: The machine has knitting tools (5) which can be connected, according to the particular pattern, by means of coupling elements (16), controllable by a control device (33), to driving elements (12) which are driven by cam discs (10). For the purpose of substantially increasing the operating speed of such machines, irrespective of whether only a choice between knitting and not knitting or tucking is possible, the object of producing the drive of the knitting tools (5) without spring forces and of making sufficiently large time segments available for the selection of the knitting tools (5) is achieved in that the driving elements (12) and cam discs (10) are constantly coupled in the driving-out and drawing-off direction, whilst, during the drawing-off strokes, both the drawing-off parts (24) of the driving elements (12) bring about a drawing-off of the previously driven-out knitting tools (5) in each position of the coupling elements (16) and all the coupling elements (16) can be brought first into one of two specific positions and then out of this into the other specific position according to the particular pattern. The invention relates, in general terms, to the sector of knitting machines and can be put into practice, for example, on flat knitting machines having knitting tools (5) driven by eccentric discs. <IMAGE>

Abstract: 214,668. Nielsen, H., Laing, B., and Boocock, M. Oct. 27, 1922. Moulding fuel; endlesschain machines; shaking and jigging machines.- Pulverulent fuel material mixed with binder is fed on to an endless band conveyer and during transportation thereon is subjected to a combined jarring and compressing action. The material, which may have been introduced to a mixer Q whilst still hot from a retort, is fed through crushing rollers into a feed box R<1> provided at its forward end with a slide r' by adjusting which the thickness of the briquette may be varied. Trough or tray sections B of a conveyer A after being filled pass under pressure rollers H - - H<2>, then under an endless band J applying an increasing pressure from rollers I - - I<3> and finally under a finishing roller L. Vibration is simultaneously imparted to the underside of the conveyer by hammers M preferably positioned directly beneath the pressure rollers. The finished briquettes are conveyed to the discharging point, being retained within the tray sections by a curved plate N, and are there ejected on to the conveyer P by means of a pivoted lever o intermittently actuated by a tappet rod o<3>, to cause loose bottoms b<2>, Fig. 2, of the tray sections to turn about their pivots b<3>. A reciprocating knife may be employed at the discharge point to divide the consolidated material if transverse division plates are not used. The vibrators may be steam-driven, exhaust steam being used to melt and inject atomized binder into a steam-heated mixer. The conveyer may be intermittently driven and reciprocating plungers employed with or without pressure rollers and an endless pressure band. The conveyer may be constructed to make several rows of briquettes.

Title: Improvements connected with rotary bottle filling and like machines
IPC: B67C3/26
Filed: 1936-11-02
Abstract: 484,403. Bottling. CHIGNELL, J. Nov. 2, 1936, No. 29721. [Class 125 (ii)] The liquid-control valve 13 of a bottle-filling machine is carried by a diaphragm 12 on that side subject to the liquid pressure in the receiver 11 transmitted through a pipe 18, the valve being thereby held closed, and on the other side subjected under the control of a valve operated by the machine to a balancing gas pressure so as to permit at the appropriate moment the opening of the valve 13 and the delivery of liquid to the bottle. The control valve consists of a rotary member 22 held to the filling head by a stationary part 21 and provided with a number of arms 29 which co-operate at appropriate points in the rotation of the machine with suitably positioned stops ; the part 21 is connected to a source of vacuum with passage-way to the valve 22. The following is the sequence of operations : at filling of the receiver, the valve 22 puts the upper side of the diaphragm 12 in communication with the vacuum pump thereby closing the valve 13, and gas pressure is admitted to the receiver 11 which furthermore is filled with liquid under pressure to the working level ; in normal operation, the valve 22 is actuated to put the bottle to be filled under vacuum, thereafter on the further rotation of the machine, the bottle is put in communication with the gas pressure in the receiver 11 by further actuation of the valve 22, and the same pressure is transmitted to the upper side of the diaphragm 12, thereupon due in part to the spring 15 the valve 13 opens and liquid is freed by the slight preponderance of pressure into the siphon tube 21 ; further actuation of the valve 22 permits liquid to siphon freely from the receiver 11 into the bottle, gas under pressure passing back into the receiver; and finally the valve 22 is brought into a position in which a vacuum is created on the upper side of the diaphragm 12, the liquid-control valve 13 thereupon closing. Should a bottle burst during the filling operation, the valve 13 automatically closes to prevent the escape of liquid, and the gas pressure in the receiver 11 is sealed by a non- return valve 45.

Abstract: 727,695. Door-operating appliances; hinges. HOLDEN, C. F. July 3, 1953 [Nov. 25, 1952], No. 29750/52. Classes 65(1) and 65(2). [Also in Group X] A pivotal structure such as a window or a door comprises a hinge member having a channel or slot therein for the reception of an edge of one or more sheets of transparent, translucent or other rigid material, and resilient means for urging the sheet or sheets of material into the channel or slot so as to retain the sheet or sheets of material in position in the hinge member. The window shown in Fig. 1 has a hinge member 11 comprising a socket 13 rotatably supporting a rod 14 having a groove 16 which receives an edge of a pane of glass 10. The bottom edge of the pane 10 has a U-shaped channel member 21 and the pane is held in the groove 16 by a tension spring 19 whose ends are secured in tongues 18 and 22 respectively formed out of the socket 13 and the channel member 21. The socket 13 is secured to the upper member 12 of the window opening by screws 17. The socket may, as shown in Fig. 2, be formed as two plates 33 and 34, spot welded together and arranged to be secured by screws 35 to the front edge of a window opening. In a further modification (Fig. 4) the hinge member comprises two sockets 100, 101 secured to a sill 102 by screws 103 and which support a rod 104 about which may rotate a number of cylindrical elements 105. A channel 106 integral with or attached to the elements 105 receives the lower edges of two panes of glass 107 and 108 which are held in position by a spring 110 attached to tongues 109 and 112. In application to doors the glass panes are replaced by sheets of hardboards or other suitable material. The tension springs 19 and 110 described tend normally to hold the window in a closed position but this action may be avoided if desired by securing that end of the spring secured to the hinge member to a moving part of the hinge member.

Filed: 1963-07-29
Abstract: 990,003. Operating television camera tubes. FERNSEH G.m.b.H. July 29, 1963 [July 28 1962], No. 29905/63. Headings H4F and H4T. [Also in Division H1] In an image orthicon the target is flooded with slow electrons, during retrace times, to remove positive charges due to background illumination, the slow electrons being derived either from a separate flood gun within the tube (see Division H1) or from the photo-cathode 4 which is illuminated uniformly by a flash lamp 17, the intensity of the flood electrons being adjusted to correspond with the background illumination. The photo-cathode is keyed during the line retrace times from its normal high positive potential to a potential of a few volts negative to the scanning beam through a rectifier circuit 32, 37 including a clamping circuit 26 which is fed from the output electrode 21 of the image orthicon. The clamping pulses are obtained from the triode 23 via phase splitter 27. The line scan pulse generator 30 supplies positive blanking pulses to the photo-cathode and also trigger the flash lamp 17. By means of a switch 34 the magnitude of the pulse applied to the flash lamp may be controlled, the pulse amplitude on the photocathode remaining unchanged. In another embodiment, the amplitude of the keying pulses applied to the photo-cathode or to the flash lamp may be controlled by a photo-cell or photo-conductor illuminated by the scene and arranged in front of the camera.

Patent GB-683944-A (GB)
Title: An electric drive for the operation of devices such as valves and the like
IPC: F16K31/04
Filed: 1948-11-25
Abstract: 683,944. Control of motors. KRECAN, J., and MEOPTA. Nov. 25, 1948 [Nov. 20, 1947], No. 30149/48.. Class 38 (iii) [Also in Groups XXV, XXIX and XXX] In a mechanism for moving a member into contact with, and pressing it against, a rigid face, an electric motor rotates a screw which engages a non-rotatable nut so that the screw and the movable member carried thereby move rectilinearly; and, although the nut can move in the axial direction, such movement is normally prevented by springs which, when stressed beyond a certain amount, allow the nut to move axially so that a switch is operated to stop the motor. The invention is shown applied to the actuation of a valve 2 by an electric motor 5, the support 7, 8 for the latter being slidable relatively to the casing 1 of the valve, and springs 11 are interposed between the two to take up the excess pressure that would normally be communicated to the valve when the latter reaches one of its limiting positions or is stopped by an obstruction. The support platforms 7, 8 for the motor are spaced apart by bolts 9 and the lower platform slides on pillars 6 upstanding from the valve casing. Rotation of the motor moves the valve closure member longitudinally through gearing 12, 13 and a screw-and-nut connection 15 between the valve stem and platform 7. When the member 2 stops moving, the valve stem will continue rotating but the platforms will start to move upwards and an abutment 16 carried by one of the pillars 6 will be withdrawn to allow a switch 17 to open and break the motor circuit. In a modification, the pillars 6 carry further springs situated between platform 7 and the valve casing, and a further switch is provided on platform 8 so that the motor circuit is broken both when the valve is fully opened or fully closed.
Patent GB-847926-A (GB)
Title: Improvements in or relating to aircraft ejector seats
IPC: B64D25/10
Filed: 1956-10-04
Abstract: 847,926. Aircraft ejection seats. FOLLAND AIRCRAFT Ltd., and DAVIES, I. J. Jan. 3, 1958 [Oct. 4, 1956], No. 30162/56. Class 4. An aircraft ejection seat has restraining straps for the occupant's legs secured to anchorages on the aircraft structure, so that on ejection, the straps are pulled through non-return buckles, and thereby shortened, the other ends of the restraining straps from the anchorage means being held on the seat by lock means releasable by connection to means which also release the harness from the seat. Fig. 1 shows a side view of the seat, and Fig. 2, the lower face of the seat pan. Each of two straps 18 extends forwardly from a snap release fastening 14, passes through a slot in a snap hook 17, returns and passes through a non-return buckle 15 on the seat pan, and thence extends to an anchorage 19 on fixed structure. Each snap hook 17 is attached to a D-ring 16 sewn to the occupant's flying suit leg or to a band 35 surrounding the leg. Each buckle 15 is such that the strap 18 may be drawn through it freely in the direction to restrain the leg against the seat, but movement of the strap in the other direction is frictionally restrained, unless a release device on the buckle is operated. On ejection, initiated by pulling a face screen 34 on a headrest 33, the raising of the seat relative to the anchorage 19 draws the strap to pull the occupant's legs against the seat. When the tension in the strap reaches, say, 500 lbs., a weak point 20 breaks, the legs being still held by the frictional properties of buckles 15. The snap releases 14 are normally held closed by rods 23 connected to a rocker 24 and lever 25, the latter being connected with the ejection sequence mechanism which operates bolts 28 securing the body harness to the seat at 30 and also at the shoulders as in Specification 844,618, so that when in the ejection sequence the occupant's trunk is released from the seat, the snap releases 14 are released, and the straps 18 are free to feed through snap hooks 17, freeing the occupant's legs. For quick release without ejection, a handle 32 on the seat can pull a cable 26 attached to lever 25, thereby releasing the snap releases 14 and bolts 28. The rods 23 may be replaced by an equivalent system of tension wires.

Abstract: 747,434. Blow-moulding plastic pottles &c. AMIGO, A. Oct. 27, 1954 [Nov. 2, 1953], No. 30273/53. Class 87(2) Two or more initially tacky bands, strips, sections or profiles 1, 2 of organic plastic material are placed between the sections 14 of a divided mould (as shown, the bands are extruded between the sections) and are kept separate from one another by blowing a stream of gas between them. Then the mould sections are brought together to close the mould and weld the bands together at the edges of the mould, and the supply of gas is continued to the interior of the mould to expand the bands, &c., into contact with the walls of the mould to form the hollow article. As shown, the gas is supplied through a nozzle 5 on the extrusion nozzle 3. Mould parts 24, 34 shape the top and bottom of the body: first 24 close in, then 14 and finally 34. Members 24 and 34 may have means for severing the body from the bands and severing the waste portion at the bottom of the body. The closed mould sections may move longitudinally away from the extrusion nozzle to leave room for another set of mould sections to close in on the bands issuing from the extrusion nozzle. Two or more articles may be blown simultaneously. Fig. 6 shows an arrangement in which an air nozzle 25 extends horizontally below the extrusion nozzle 23, the air nozzle reciprocating in the direction of arrow D.
