Title: Improvements relating to methods and apparatus for curing vinyl resin foam
IPC: C08J9/04
Filed: 1956-04-09
Abstract: <PICT:0818418/IV (a)/1> <PICT:0818418/IV (a)/2> A plasticized vinyl resin foam is cured by simultaneously exposing the resin to a field of radio-frequency electrical energy for heating the resin from within and to a source of heat for heating the resin from a point without, the heat from the source being increased as the temperature of the foam increases due to heating from within to maintain the ambient temperatures surrounding the foam at the same level as the temperature of the foam, at least until the foam reaches a temperature above gelling temperature. It is preferred that after the foam reaches a temperature above gelling temperature but shortly before it reaches minimum fusion temperature, the rate of input of electrical energy is reduced, preferably stopped and the ambient temperature increased until the temperature of the outside of the body of the foam is at least equal to the inside temperature and then the exposure to a field of radio-frequency energy resumed so as to fuse the foam.  Vinyl chloride polymer or copolymer plastisols are the preferred resins. Referring to Fig. 3 the foam in mould 2 is heated between spaced electrodes 4 and 5, 4 being connected to a source of radio-frequency current 6 while electrode 5 is grounded. The ambient temperature is controlled by the series of coils 7, 8 through which a heat transfer fluid may be circulated.  These coils may be replaced or supplemented by radiant heat lamps 9 set in reflectors 10.  Referring to Fig. 5 for continuous operation grounded electrode 21 supports conveyer belt 22 carrying the foam below electrode 26, the heat transfer tubes being 27 and 28 while the third electrode 29 is set at an angle so as to reduce the effective voltage during the fusion stage.  Specifications 737,367 and 770,237 are referred to.

Abstract: 712,030. Projectiles. MILLER, T. W. Feb. 6, 1945 [June 5, 1944], No. 10756/44. Class 9(1) A mortar bomb of streamline form comprises a recess at the root of the tail to hold the primary cartridge 13 of the propelling charge. The cartridge is fired by a striking pin 12 slidable in the spine of the tail which is shaped to continue the streamline form of the bomb. The pin 12 forces the cartridge against a firing pin 16. Vents 23 allow the cartridge 13 to fire the secondary propelling charges which are tied with the aid of apertures 26 between the fins 10 of the tail, or slots 27 may be used which allows the cord to be blown off the tail and consequently does not impede the flight of the bomb. A safety pin 17 is withdrawn before firing. A crushable ballistic cap 3 is screwed on to and covers the percussion fuse 4 of the blasting explosive 25.

Title: Improvements in or relating to toy guns, and the like
IPC: F41C3/08
Filed: 1919-05-02
Abstract: 137,982. Owen, B. May 2, 1919. Guns firing caps; projectors.-A toy machine gun in which a long strip of paper caps is used has means for projecting a bullet, and the mechanism for feeding the caps and ejecting the bullet are operated by the rotation of a crank. The body 1 has near its lower end a chamber 2 for the strip of caps, which is fed upwards to the hammer 16. The feeding-device consists of a spring-controlled pawl 13, Fig. 2, pivoted on a vertically-sliding plate 8 which is moved upwards by a cam 12, Fig. 1, secured to one end of the crank-shaft 38. A cam 23, Fig. 3, secured to the other end of the crank-shaft operates a lever 19 which raises the hammer 16, a spring 20 returning the hammer to explode the cap. A spring 8<a> draws the plate 8 downwards when the strip of caps is returned by the hammer and the pawl slides over the strip. A spring-operated plunger 26, Fig. 1, in the barrel 24 ejects the projectile, and is connected to an arm 29 which slides in a slot 30 having a downward extension 31 at its inner end. The cam 12, in its rotation, strikes the lower end of a camplate 32, causing the upper end to lift. the arm in the slot 31, thus allowing the plunger 26 to eject the projectile.

Title: Improvements in and relating to Doffing Mechanism for Spinning Frames.
Inventor: BINNS WILLIAM
IPC: D01H9/04
Filed: 1918-07-04
Abstract: 135,879. Binns, W., and Mander, J. D. July 4, 1918. Doffing-arrangements; spindle apparatus.-In arrangements applicable to cap spinning-frames in which the devices for removing the full bobbins and replacing them by empty bobbins are pivoted on the frame, so that during spinning the devices lie below the spindles, and the devices adapted to receive the full bobbins and to carry the empty bobbins are rotatable about a subsidiary axis mounted on the dotling-mechanism, the mechanism comprises forks to engage the caps mounted on hinged arms adapted to move through 180 degrees, a series of bobbin clips and bobbin trays mounted on arms having a similar movement, and means to move the mechanism vertically to effect the necessary operations. The doffing-mechanism is carried by brackets 6, Fig. 1, mounted on a frame 4 secured to the spinning-frame. A rack 8 gearing with a pinion 7 in the bracket carries a shaft 9 on which is mounted arms 10<a>, 11<a>. The arm 10<a> carries a fork 12 to engage the cap 3. The arm 11<a> carries a subsidiary axis 16 carrying the clips 17 to engage the full bobbin and a tray 18 to carry the empty bobbin. The arms 10<a>, 11<a> are connected by a lost-motion arrangement, so that the arm 10<a>, when rotated, moves first independently and then carries the arm 11<a> with it. In doffing, the arms 10<a>, 11<a> are first swung about their shafts into the positions 10<b>, 11<b> to cause the clip 17 to engage the full bobbin and the fork 12 to engage the cap. The rack 8 is then raised to lift the arms into the positions 10<c>, 11<c>. The subsidiary axis 16 is then rotated to place the empty bobbins above the spindles, and the rack 8 then lowered. In a modified arrangement, the arm carrying the fork for engaging the cap is mounted on a shaft carried at the end of the arm carrying the full-bobbin clip and the tray for the empty bobbin. The former arm is operated by a lostmotion arrangement so that it moves with the latter arm through substantially 180 degrees and is then itself rotated through about 180 degrees. In a further modification, a bracket 40, Fig. 6, carries an arm 43 at the end of which is a spindle 45 carrying the clip 47 and tray 48. The arm 49 carrying the cap fork 50 is pivoted to the arm 43 at 51. The arm 43 is rotated by gearing 46, 42. To maintain the load on the shaft 41 constant, a spring cable 52 passes over a drum 53 moving about the axis of a shaft 54, from which the gear-wheel 55, which operates the shaft 41, is driven, The spindle rail may be moved horizontally before doffing, and the spindles may be lowered. An arm carrying full-bobbin clips and empty-bobbin trays mounted on a pivoted bracket, the arm being adapted to be swung through about 180 degrees, may be applied to a ring spinning- frame. The bobbins may be provided with driving-cheeks 61, 62, Fig. 10, which engage with the pins on the spindle.

The outlets for the main conditioning air are through holes at the top of vertical shafts 11 positioned on the wall of the compartment below the window 12. The supplementary air leaves by slots 13 on each side of the shaft 11 located under the seats. Thermostats are provided in the compartments and are connected in series so that as soon as the desired temperature has been reached in all compartments the heater 7 is switched off. The connections between the ducts 9 and the outlets 13 are controlled by rotary flaps 15 actuated by individual thermostats in the compartments through rotary magnets. A flap valve may be provided immediately downstream of the cooler 5 to enable cooled air to be sent through the supplementary duets 9, e.g. to cool a train that has been standing in the sun.
