Title: A new or improved imprinting attachment for labelling machines applicable also to gumming the labels
IPC: B65C9/46
Filed: 1923-10-17
Abstract: 227,524. Webster, R. W. Oct. 17, 1923. Labelling.-A device for attachment to bottle - labelling machines for gumming the centre portion of the labels not touched by the usual gummed pickers, comprises a slide block reciprocated along a slide bar and having a projecting arm carrying a gumming - element, the slide bar being turned at the end of each stroke of the slide block to lift the gummer into contact with a level when in forward position, and with the gumming-pad when in rearward position. The gumming device is carried by a slide block h, which is guided along a square slide bar f supported by brackets e, g depending from a frame d fixed to one of the side frames a of the labelling machine, and is reciprocated by a connecting rod o and oscillating lever q. At the end of each stroke of the block h, the slide bar f is rocked to lift the holder m carrying the gummer n alternately into contact with a label in the holder 6 and with the gumming-pad 7 by means of a lever r connected by a rod s, lever t, and link u to a lever v on a shaft w. The shaft w carries a lever y having a roller z running on a cam drum 2 with cam projections 4, 5 adapted to raise the lever against the action of a spring 3. The slide block h is permitted the necessary dwell at the ends of its travel by interposing springs p at its point of connection with the connecting-rod o. When a gumming-roller is employed in place of the block n, the cam projections 4, 5 are made longer so as to keep it in contact with the label and gumming-pad during the end parts of the stroke of the lever q. The gumming-pad is preferably supplied from a separate container 8.

Title: Electrolytic Gas-Generating Cell
Inventor: LITTLEWOOD ANTHONY BLAIR
IPC: C25B9/19
Filed: 1965-06-21
Abstract: 1,153,631. Electrolytic gas-generating cell. W.A. WISEMAN. May 31, 1966 [June 21, 1965], No.26086/65. Heading C7B. An electrolytic gas-generating cell (e.g. for producing O 2 , H 2  or Cl 2 ) comprises a body of porous inert insulating material 2 and two metal electrodes 1, 3 in close contact therewith surrounding a central space 4 into which gas liberated at the inner electrode 1 can flow. A gas inlet 5, for a different gas from that liberated, leads to the space 4 so that liberated gas can be scavenged and a gas outlet 6 leads from the space, the space being of an unconstricted and unencumbered nature. The inner electrode 1 is permeable and, as shown, comprises a coil but may be a gauze or be manufactured from metal powder. The porous inert material may be sintered synthetic plastic, sintered ceramic material or filter paper. Fig. 1 (and Fig. 2 not shown) illustrate a Pt wire coil anode 1, a tight roll of porous polyvinyl chloride 2, e.g. impregnated with H 2  SO 4  solution, and an Ag gauze cathode 3. Oxygen produced at the anode passes into a scavenging gas stream entering at 5 and leaving at 6. Fig. 3 (not shown) illustrates a modified cell wherein the inner electrode is a Pt gauze (7) held in contact with the insulating material 2 by Pt spacers (8). As water is electrolyzed from the electrolyte it can be replaced in the porous material by a wick. A depolarizing system can be used around the cell to prevent evolution of hydrogen at the cathode. The cell may be used in the reaction coulometer system of Specification 1,112,771.

Title: Safety harness device
IPC: B60R22/38
Filed: 1956-08-27
Abstract: 805,358. Safety harness brake devices. PACIFIC SCIENTIFIC AEROPRODUCTS. Aug. 27, 1956 [Sept. 6, 1955], No. 26190/56. Class 103 (1). An inertia operated safety harness device adapted to automatically lock persons in aircraft and other moving vehicles in their seats during crashes and similar occurrences, as disclosed in Specification 761,518, [Group XXXIII], include two tension members or harness straps 12 and 13, which pass over the shoulders of a pilot or passenger, such harness straps being anchored to a spool or drum 1 in a manner, as shown in Fig. 4, by a self-tightening pin 15 and set-screw 17. The spool 1 is acted upon by a coil spring 21 in a central axial space therein so as to wind or unwind the straps in response to movements of the pilot's body, an inertia weight 23 in the form of a ring being rotatable with one end of the spool. If the webs 12 and 13 are fed out at less than a predetermined acceleration, the inertia member 23 rotates with the spool, but when the pull exceeds such value of acceleration, the inertia member tends to remain stationary as the spool rotates, thus causing link 28 to pivot and tip the drum shaft 32 which, in turn, pivots arm 35 to trigger the sear 38 and release pawl 39. Pawl 39, tensioned by the pawl spring 56, pivots to engage the ratchet teeth 41 located in the periphery of the inertia member. The spool is thus restrained from further rotation in the unwind direction but the pawl will ratchet over the ratchet teeth to permit the spool to rotate in the wind-up direction. Means for providing a positive internal stop for the spool in the windup direction is shown in Fig. 2, in which the device is shown in the fully wound-up condition in which a pin 45 embedded in the inertia member 23 forces the arm 44 of a fly-stop 43 freely rotatable on the bearing 3 against a fixed stop 46 on the casing 4. When the webbing is unwound the pin 45 can rotate so as to engage the back face of arm 44 and then make almost another three quarters of a revolution before the arm 44 strikes the stop 46 again on its other face.

Abstract: 632,657. Sheathing electric cables. STANDARD TELEPHONES & CABLES, Ltd., and PHEAZEY, J. R. Aug. 30, 1946, No. 26208. [Classes 83 (ii) and 83 (iv)] [Also in Group XXXVI] Uniting by fusion; brazing.-A flexible sheath for an electric cable of circular, oval, rectangular, polygonal or asymmetrical cross-section is made by continuously wrapping, strip, tape or braid about the cable or an equivalent mandrel and passing it through a high-frequency heating device to unite the strip into a continuous sheath. The strip 1, Fig. 1, is helically wound with lap or butt edges and is united by fusing the tape &c. if of metal or a solder or braze coating thereon. The processes may be carried out in air, vacuum or special atmosphere, and the solder is applied by plating, painting, spraying or in paste, strip or wire form, with or without flux. The tape may be coated by electro-plating, hot-dipping, &c., and soldercoated aluminium and its alloys may be used. Two tapes 1, 5, Fig. 2, may be consecutively applied with the same or opposite hands and united singly or simultaneously. More than two layers preferably are heated separately. The strips may have special mating or interlocking edges and be fluted or corrugated, or may be bent around the cable to form a longitudinal butt or lap joint (Figs. 4 and 5, not shown). In a modification, non-metallic strip is used, e.g. paper, polystyrene, polyvinylchloride, &c. metallized on both surfaces or on one surface or at the edges for butt and lapped joints or on one surface for inwardly or outwardly-flanged joints 6, Fig. 6, which are subsequently flattened down, 7, to the sheath surface. In a further modification, the sheath may be stationary and the induction means is moved relatively to it. In another form, a plain tube may be finished through a drawing die or may be corrugated after jointing. In another modification, metallic plastic tapes are interleaved or covered ' with metal layers. According to the Provisional Specification the process is applicable for making tubes, the strip is wound under tension, and a combination of layers with longitudinal and helical joints is used. Also, plastic or paper tube may be extruded and then sprayed with metal which is induction heated to form an impermeable tube. Powder metallurgy.-Further, a pair of concentric metallic or non-metallic tubes may have the interspace filled with metal powder induction heated to fuse and form a joint or an impermeable layer.

Title: Improvements in or relating to cathode ray tube display arrangements
IPC: G01S7/22
Filed: 1959-07-31
Abstract: 863,110. Cathode-ray oscilloscopes; radar; valve pulse circuits. TELEFUNKEN G.m.b.H. July 31, 1959 [Aug. 13, 1958; April 24, 1959], No. 26363/59. Classes 40(6) and 40(7) An arrangement for intensity modulation of a part of each line of a raster (or part thereof) in order to display a locus on a cathode-ray (C.R.) tube screen includes means whereby the modulated portions of the raster lines which make an acute angle with the locus are progressively increased in length as that angle decreases, whereby the locus is a substantially uninterrupted line. The invention is described as applied to the display of a glide path on a radar groundcontrolled approach range-elevation display; the possibility of mistaking the longer-range parts of the displayed marker for echoes is thus reduced without increasing the number of lines in the raster, Fig. 2. In the first embodiment known marker intensity-modulation pulses are fed to valve 1 which produces a sawtooth output pulse consequent upon the discharge of capacitor 3 through the valve followed by its re-charge via resistor 2. Positive rectangular pulses each of which begins at the start of a raster line and ends at its termination are applied to valve 4 input and each pulse produces by the action of relatively large capacitor 6 a linearly-falling voltage which is combined with the above sawtooth waveform, the combined wave being passed via biased diode 7, limiter 10 and cathodefollower 12 to intensity modulate the C.R. tube by pulses whose durations are proportional to the time delay between the input to valve 1 and the leading edge of the input to valve 4. To afford uniform brightness along the marker line the intensity-modulation pulses may be of amplitudes inversely proportional to their durations, or the output of cathode-follower 12 may be fed via a free-running blocking oscillator so that each "dash" of the marker line is composed of short pulses of equal amplitude, Fig. 4 (not shown).

Abstract: 281,829. Jones & Shipman, Ltd., A. A., and Shipman, F. Oct. 23, 1926. Drilling. - In drilling- machines of the high-speed sensitive type having a balanced spindle, a rod or stud is provided mounted on and parallel to the drill spindle, or the usual sliding bearing therefor, and acted upon by resilient means to balance the spindle during and return it after its operative movement. In one form the bearing 4 movable with the spindle 2 carries a clip or bracket 3 to which is attached a plunger 1 acting through a head 7 on a compression spring 5 located within a tubular housing 9 attached to the arm 6 through which the spindle slides, the compression of the spring being adjustable at 10. The spring may be replaced by pneumatic means, the plunger then acting as a piston so as to compress air on one side and create a vacuum on the other side or perform either function. The clip 3 may be arranged above the arm 6, the plunger then extending downwards and the spring may act on a lug instead of being located in a recess. In a modified form two or more resilient means are arranged to act telescopically so as to provide a longer stroke of the spindle. According to an example of this form the spring 5 acts on the closed lower end of the housing 9 and the latter is provided with an external flange at the top which acts on a surrounding spring located within a recess in the arm 6 and bearing against a flange secured against the bottom of the recess. In another form the resilient means take the form of a rubber &c. tube filled with air whose pressure is controlled by a pump and valve. this form being stated to be particularly useful for small machines.

Abstract: 1455012 Cathode-ray tubes AGFA-GEVAERT 8 May 1974 [4 June 1973] 26582/73 Heading H1D A charged particle emission pattern in an hermetically sealed envelope, and produced, for example, by the incidence of an X-ray, ultra-violet, visible, or infra-red image on a photocathode, is recorded as an electrostatic charge pattern on an electrically insulating surface of a charge receiving material disposed within the envelope, and is subsequently transferred through a pin matrix portion of the envelope on to another insulating charge receiving material removably positioned at the outer surface of the envelope. In Fig. 1 the endless belt 10 has rigid insulating plates secured thereto, or is formed by a plurality of such plates hinged together, the belt passing over the conductive guide plates 12 and 13 which permit the production of suitable electric fields above the belt, the image from the photocathode 8 being received upon one of the belt plates which is hereafter moved by rotation of rollers 11 to contact the inner surface of the pin matrix 5 to transfer the charge pattern to the outer belt 1 of charge-receiving material, the inner belt being of photoconductive material to permit its discharge for re-use by a radiation source 14. The photocathode is spaced 0À3 to 3 mm. from the belt 10, and may be provided with a microchannel plate to remove electrons diverging at too great an angle from the normal to the photocathode surface. To increase the speed of image formation, the envelope 15 is either gas-filled-e.g. with a mixture of argon and monobromo-trifluoromethane at a few torr above atmospheric pressure-to produce avalanching, or is evacuated and incorporates a channel electron multiplier, which may have its channels tilted with respect to the normal to the photocathode surface, and which may be supported from the cathode by an insulating microchannel plate the channels of which are larger than, but register with, those of the channel electron multiplier. A further embodiment, of which Fig. 4 represents only that part beneath the photocathode 61, employs both the above methods, 66 being a channel electron multiplier mounted in an evacuated portion 62 of the tube, the resulting electron image passing through a second microchannel plate 72, which may or may not be secondary electron emissive, and a window 73 of aluminium, nickel, or alumina, into the remaining portion of the tube which is gas-filled and contains the continuous belt 77. Reference is made to the use, instead of a photocathode, for producing the charged particle stream image, of either an information modulated electron beam scanning a secondary electron emissive source, or-for an incident X-ray image-a gas filling of atomic number greater than 36, e.g. xenon.
