IPC: B41J25/20
Filed: 1922-06-26
Abstract: 191,699. Remington Typewriter Co., (Assignees of Seib, G. A.). Jan. 16, 1922, [Convention date]. Accenting - arrangements; ink-ribbon mechanism; letterspacing mechanism.- In arrangements comprising accenting-keys adapted to operate the ink-ribbon vibrator without operating the letterspacing mechanism, the vibrator --connections comprise a rock-shaft which is mounted on a case - shift frame and is operated by the accenting-keys only; preferably, the rocK-sM.ft is mounted on a universal bar which is mounted on the shift frame; the vibrator may be associated with multicolouradjustment devices. The invention is shown in Fig. 4 applied to a portable machine having ink-ribbon mechanism similar to that described in Specification 166,775 and comprising a vibrator connected to a rocking frame 74 which is coupled-by means of a wire 85 to a finger 86 on an arm 56 secured to the universal-bar frame 51, the throw of the vibrator being adjusted by moving the wire longitudinally to cause either the main part or an offset to engage the finger. The universal-bar frame consists of plates 51, 53 secured to rocking arms 42, the plate 53 having tongues 51, of the kind described in Specification 159,387, for engaging the key-levers 23. The escapement rocker 41 is formed with a finger 61 engaging a pin 60 on the arm 56. The above-described mechanism is mounted on the carriage-shift frame 31 and is operative in either shift position. According to the invention, a rook-shaft or wire 91 is mounted, in a bracket 87 on the universal-bar frame, and is formed with a bend 94 engaging the wire 85, and a bend 93 engaging one or more accenting-key levers 24, 25 at the side of the keyboard, the tongues 54 corresponding to the accenting-key levers being removed from the universal-bar frame. The normal key-levers 23 rock the universal-bar frame and thereby actuate the escapement rocker and the ink-ribbon vibrator, whilst the accenting-key levers rock the shaft 91 and thereby actuate only the ink-ribbon vibrator, the connections being operative in either shift position. The accenting-types may be offset in the manner described in Specification. 181,383. In a modification, a rock-shaft 95, Fig. 7, mounted on the universalbar frame and formed with a finger 98 engaging the wire 85, is provided with a comb 100 having teeth 101 in register with the key-levers, the teeth corresponding to the normal key-levers being broken off. The arrangement permits a typebar at any part of the basket to be employed for accenting.

Title: Improvements in and relating to seat ejection mechanisms for aircraft
IPC: B64D25/10
Filed: 1956-06-07
Abstract: 815,058. Aircraft ejection seat mechanism. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO. Ltd. May, 1, 1957 [June 7, 1956], No. 17596/56. Class 4. The firing mechanism of an aircraft ejection seat gun is restrained by two independent means releasable in either order, one of the means being released by displacement or jettisoning of a cover normally covering an opening in the aircraft through which the seat is to be ejected. The Fig. shows part of a fixed outer cylinder 3a and a movable inner cylinder 3 attached to the seat. The inner cylinder is screw threaded to receive the breech housing which is in two screw threaded parts 1a, 1, the latter receiving the cartridge 6 and being apertured at 4, 5 to admit pressure fluid from the cartridge to the cylinders. The firing mechanism comprises a tube 9 with a screw threaded base 11 apertured at 43 for passage of the firing pin, and with a crenulated end 14 for co-operation with a spanner. A firing pin carrier 17 is retained in tube 9 by a split ring 12, and has an axial bore containing the firing pin 16. The latter is spring urged to the firing position, but is restrained by a sear 42 passing through a slit in the firing pin and located between a pin 25 in the firing pin and rollers (not shown) on pins 62, 48 mounted in lugs 63, 49 on the carrier 17. The firing pin is also restrained by the engagement of pin 25 with cam surfaces 51 on a carrier 47a pivoted on pin 48, and normally held in the position shown by a plunger 52 secured to the cockpit canopy 53. Thus jettison of the canopy and manual withdrawal of sear 42 free the firing pin. A time delay is obtained by engagement of a rack (not shown) on the firing pin with a gear train terminating in a star wheel 39 and rocker 41. Movement of the firing pin after release is thus slowed down until the rack has disengaged from the gear train, whereupon the firing pin strikes home. Specifications 583,257, 652,131, 763,580, 763,581 and 815,059 are referred to.

Filed: 1936-06-25
Abstract: 480,672. Cathode-ray tubes. RADIOAKT.-GES. D. S. LOEWE. June 25, 1936, No. 17637. Convention date, June 25, 1935. [Class 39 (i)] In a television receiving tube an image of the cathode or of a cross-sectional plane adjacent the cathode other than an aperture in a diaphragm is produced on the screen by two collecting lenses, the first of which is too weak to produce an image. As shown, the gun comprises a cathode 2, an anode 3 and a Wehnelt cylinder 4. The first lens consists of two cylinders 5, 6, of which the former may be connected to the cathode and the latter to the anode 3. An image of the cathode just beyond the fluorescent screen 9 is produced, and the image is brought onto the screen by a second lens 8 set up by cylinders 6 and 10. The anode 3 may have a cylindrical portion extending towards the cylinder 5, and the Wehnelt cylinder may have a front extension. The dimensioning of the lens systems is discussed in detail. Specifications 442,511 and 442,724 are referred to.

Title: Improvements in timber and articles made therefrom
IPC: E04C2/12
Filed: 1934-06-14
Abstract: 425,809. Sheet-wood material. ELMENDORF, A., 38, Claremont Square, Pentonville, London. June 14, 1934, No. 17671. Convention date, June 14, 1933. [Class 145 (ii)] [See also Groups X and XVII] A thin wood sheet 1 is partly cut through along a number of parallel lines 2, Fig. 2, extending from end to end in the general direction of the grain ; the sheet is then stressed across the grain to rupture the web portions into strands. The stressing may be effected by bending, or the knives used may be wedgeshaped so as to rupture the webs concomitantly with the slitting. The sheet may then be expanded to form gaps 5, Fig. 4, across which extend the connecting strands 6. These gaps may be filled with elastic material by pressing the sheet down on to a mass of filling material which is thus forced up into the gaps. The filling material 12, Fig. 9, may comprise rubber latex having mixed therewith ground mica, talc, &c., which facilitates subsequent sanding. The filler may comprise a drying oil such as chinawood oil. The sheet may be covered with a flexible backing which may be of the same material as the filler, or may be waterproofed felt 14, Fig. 9. In the manufacture, the asphalted felt is sized and treated with casein glue which forms with the latex a bonding layer 20. The constructions so far described are stated to be particularly suitable for flooring. Wood slit and ruptured as described above, but not expanded to form gaps, may be backed with a sheet of tough paper, and is suitable for collapsable boxes. V-grooves are cut in the panel which is bent up to form a box, Fig. 12, the contacting edges being secured by tape 29. End frames comprise four cleats mitred together, each comprising a solid core 31, Fig. 13, enclosed on three sides by the panel material, and secured by staples 30. The end walls 32 comprise veneers faced on both sides with paper. The box is strengthened by straps 33. The material may be produced by a continuous process, in which veneers are glued edge to edge on paper unwound from a roll, a quick setting adhesive such as sodium silicate being employed ; the composite sheet is operated on to slit and rupture the wood, the paper preventing the formation of gaps, and the resultant material rolled up.

Abstract: 221,606. Hill, R. M., and Robinson, E. July 13, 1923. Shock absorbers, applications of; land-wheels. -In an aircraft undercarriage for absorbing both lateral and vertical shocks, the wheels are rotatably mounted on a common axle or on separate axles guided under the action of shock absorbing means, by vertical and horizontal guides. In the form shown in Fig. 1, each wheel 12 is mounted on a separate axle 6 which slides horizontally in a sleeve pivoted on a fulcrum pin 8 and acting as a horizontal guide for the axle. Rubber cord looped over spools 11 mounted on the undercarriage framework and spools 10 fixed to the inner end of the axle, absorb lateral shocks. The axle slides in a rigid vertical guide in the undercarriage framework 7. A known form of shock absorber 14 absorbs the vertical shocks when the axle moves about the fulcrum pin 8. A spring 13 between the sleeve and the axle end serves as a buffer on the return movement of the axle. According to a modification in which lateral shocks in two directions are absorbed, the axle 6, Fig. 3, is centralized by rubber rings 15, separated by metal washers 16, fitted on each side of the fulcrum pin 8. An internal or external oil dash-pot may also be fitted. As shown in Fig. 3, a dash-pot cylinder 17 is secured inside the axle, and a plunger 18, pierced with leak holes, is connected to the fulcrum pin 8. In another modification, the ends of the wheel axle, which is centralized by rubber rings 21, Fig. 4, slide horizontally in sockets 23 mounted upon vertical dash-pot struts 7. A dash-pot device similar to that shown in Fig. 3 may be combined with this arrangement to assist in absorbing lateral shocks.

Title: An apparatus for washing tumblers and like receptacles
IPC: A47L15/16
Filed: 1944-09-25
Abstract: 581,235. Washing tumblers &c. SMITH, R. M. Sept. 25, 1944, No. 18274. [Class 138 (i)] Tumblers &c. are washed while supported in an inverted position upon a holder 14 integral with a sleeve 13 which slides upon a water-supply pipe 6 fitted with apertures 12 for spraying the insides of tumblers, the outsides being at the same time sprayed by jets issuing from vertical pipes 8 and horizontal pipes 10a arranged in a casing 2. The supply of water is controlled by a valve which is opened automatically upon depression of the holder 14 and which closes automatically after a predetermined interval. The holder 14 is rotated so as to ensure that all parts are cleaned. A flange 17b on the sleeve 13 operates to close a mercury switch 35, which starts the driving-motor, by operating a counter-weighted lever 19, Fig. 6, which rotates a counterweighted lever 22 counter-clockwise in Fig. 9. This actuates a lever arm 24 fitted with a hooked trip member 25, and the member 25 releases a second trip member 26 from a stop 26a and moves a lever 27 counter-clockwise, causing an arm 30 on the shaft 27a of lever 27 to act upon an arm 31 of the mercury switch 35 and so start the motor. The lever 27 carries a flange 28 which normally holds an arm 46 of a pivoted catch 46a free of projections 43 on a freely mounted disc 42 which is driven by worm gearing when the motor starts. The catch 46a is carried by an upper disc 44 which is driven on engagement of the catch, and a cam 47 on the disc 44 actuates a lever 50 which opens the valve of the water supply. The motion of disc 44 is transmitted to the sleeve 13 by gears 52, 53, 54, the gear 53 having deep teeth so as to maintain the drive in all positions of the sleeve. At the end of a complete rotation of disc 44, cam disc 47 closes the valve, and projections 55, 56 on disc 44 actuate means to trip the latch 46a so as to cut-out the drive of the disc 44, and also an arm 38b moves the switch 35 to open position. The sleeve 13 is mounted so as to prevent escape of liquid to the casing 3 which encloses the operating devices, its upper end being connected to a short sleeve 15 having a fluid-tight connection 15a with the pipe 6, while a short sleeve 16 is secured to the base of casing 2 and encloses the sleeve 13 and is enclosed by an outer sleeve 17 making a fluidtight connection 17a with the sleeve 13. The valve may be hand-operated, and the means for holding tumblers may be replaced by a device in which a number of wine-glasses may be held in an annular member carried by a shorter holder connected to the sleeve 13.
