Abstract: 424,772. Puzzles; game apparatus. COCKS, T. W., 59, Canadian Avenue, Catford, London. Aug. 18, 1933, No. 23126. [Classes 132 (ii) and 132 (iii)] A jig-saw puzzle has one or more representations A, B, C, D, E, F, the parts 3, 4, 5, 6 of one representation being interchangeable with similarly shaped parts, for example, of other representations to form different representations, such as F, having distorted features. For playing a game the parts of the puzzle are provided with inscriptions, pictures, words and/or letters, and a die is provided certain of the facets of which bear corresponding inscriptions, &c. The representations A, B, C, D, E, are photographs or prints of a flat or semi-flat tone without shadow effects and may be mounted on a base of cardboard, wood, thick paper, rubber or metal. Parts of the puzzle can be removed from position by a suction device or resilient cup or by a magnet when the puzzle is made of tin, steel or other metal. The background may or may not be out in the manner of a jig-saw puzzle and the parts of the puzzle may or may not be arranged to interlock. The background of the puzzle may be cut so that pieces are shaped to represent different animals or the background may include representations of eyes, noses and mouths which can be interchanged with the equivalent parts of the representations A, B, C, D, E, and F. Interchangeable parts may be provided separately for substitution in the puzzle. Each representation may be of circular, rectangular or octagonal shape. The representations may be in relief and the rear side of the puzzle may have a further set of representations or another jig-saw puzzle. In the example shown the centres of the eyelid openings in one representation correspond in position with the centres of the eyelids openings in the other representations. This is accomplished by utilizing a mask or screen, Fig. 2, of ground glass and by re-photographing the original photographs with a focusing camera, the eyelid openings being arranged to be coincident with a transverse line 7 on the screen. Alternatively the screen may comprise a sheet of glass or transparent paper and the photograph may be projected on to a screen.

Title: Method and apparatus for producing Tapered Metal Tubing
Inventor: HINSHAW JOHN WESLEY
IPC: B21C1/26
Filed: 1967-05-18
Abstract: 1,189,135. Drawing. BATTELLE DEVELOPMENT CORP. 18 May, 1967, No. 23221/67. Heading B3P. A metal tube is tapered by forcing a tube and tapered mandrel through a deformable drawing die or forcing the die over the tube and mandrel so as to cause the die to deform and the tube to be drawn on to the mandrel. In one embodiment, Fig. 3, one of two plate members 24, 26 is moved relative to the stationary other to draw the tubing 20 through a brass die 34 containing 80-90% Cu against-a tapered mandrel 10 without any reduction in the wall thickness. The die 34 and mandrel 10 may be rotated relative to each other. The die 34 is held between a pair of semi-circular segments 36, 38 resiliently biased together by a spring loop 40, and may be notched at its trailing end (Fig. 7, not shown) to reduce the amount of die material when a tube having a large amount of taper is to be produced. A tube also having a tapering wall thickness may be formed by first drawing a tube over a slightly tapered mandrel through a conventional die of fixed internal dimensions to apply a taper to the wall thickness, after which the tube is tapered without any further change in the wall thickness using the apparatus of Fig. 3. At least a portion of the mandrel 10 may be non- circular, e.g. square, hexagonal or the mandrel 10 may have stepped, tapered portions. Two tubes may be laminated together. In a further embodiment, Fig. 11, a tube tapered inwardly and then outwardly is formed by positioning a die 80 between a back-up plate 72 and a split die 84. The latter is moved towards the former to cause the front end of the die 80 to be cammed inwardly so that the tube 20 is drawn over the mandrel portion 68. When the tube 20 has been drawn completely over the mandrel portion 68, the die halves 86, 88 of the split die 84 are separated and the drawing of the tube 20 over the mandrel portion 70 is carried out using the die 80 only. The mandrel section 68 may be omitted and the sequence of the two tapering operations repeated along a length of tubing. The tubing may be of copper, brass, aluminium, nickel or stainless steel.

Filed: 1922-08-29
Abstract: 210,473. Hadfield, Sir R. A., and Clerke, A. B. H. Aug. 29, 1022. Springs.-In apparatus for bending and quenching spring blades for laminated springs, of the type in which a number of pairs of relatively adjustable bending and holding dies are carried by frames on a horizontal rotatable shaft arranged over a quenching tank into which they are in turn immersed, and in which the shaft is temporarily retained by holding means in a horizontal position to admit of removal of the finished blade and the insertion of a fresh strip, the shaft, on release of the holding means, is automatically rotated to bring the frames in turn into the required position. The shaping surfaces a<1>, b<1>, Fig. 1, of the dies a, b are serrated or provided with projections of pyramidal, conical or other shape to allow the quenching liquid to come into contact, with the surface of the blade A after bending. A series of pairs of bending-dies are mounted on frames i secured to spiders n' carried by an intermittently-rotated shaft n so that they may be immersed in a tank o containing quenching liquid, which may be circulated therethrough to maintain it at the desired temperature. The dies a are rigidly fixed to the frames by pin and slot connection j and the dies b are moved forward thereon to bell crank levers m, connected by a link m<4> to a hand lever m<2>. to bend and hold the blade, being guided by slots k<1>. One of the frames is arranged in a horizontal position during bending by a spring-pressed stop s engaging underneath a lug i<1> on the frame arm, and having a weighted and pivoted detent a engaging the upper surface thereof. The stop is retracted by a lever t so as to allow the frames to rotate so as to bring the dies with bent blade on to the quenching tank, and to bring the succeeding pair into the bending position. The rotation of the frames is effected by pumping water from a second tank 1 through a pipe 3 in turn into a series of receptacles x carried by arms on the shaft n, corresponding in number to the frames, the water being discharged from the receptacles when they reach the lower portion of the tank. In a modified form of bending-dies, a series of feathered rods e, Fig. 4, with wedge-shaped heads e<1>, Fig. 6, are adjustably mounted in their holders and secured in position by screws f. They may be pressed forward by springs g when the screws are released and may be set by a template or by a previously shaped blade. The blade may belocated by a pin h passing through the hole made therein to accommodate the centre bolt, or by substituting an end stop for one of the rods e. When bending short blades, two blades may be bent simultaneously by the rods on the right and left portions of the holder respectively.

Title: Improvements in and relating to varnish and paint constituents
Inventor: KING CHARLES WILLIAM HENRY
Filed: 1948-09-06
Abstract: A paint or varnish constituent consists of tall oil esterified with pentaerythritol in the presence of dehydrated castor oil. Paints or varnishes prepared with this material do not remain tacky after drying as is stated to be the case with paints &c. made from tall oil esterified with pentaerythritol and subsequently mixed with dehydrated castor oil.  Preferably an excess of 10 to 30 per cent in the amount of pentaerythritol theoretically required to reduce the acid value of the tall oil to the desired extent is used.  In an example, Swedish tall oil is heated with dehydrated castor oil and pentaerythritol in the presence of zinc oxide as catalyst to 265 DEG C. for four hours in an atmosphere of carbon dioxide.  The pale viscous product is dissolved in white spirit to form a varnish. Other varnish oils such as linseed, stand oil, tung oil, and oiticica oil, may be added to the reaction mixture together with additional resins such as glycerine ester gum, pentaerythritol ester gum, copal glycerine ester, or a rosin-modified phenolic resin.  A paint is described containing zinc oxide, varnish constituent as above, white spirit, cobalt-linoleate and lead naphthenate.ALSO:A paint or varnish constituent consists of tall oil esterified with pentaerythritol in the presence of dehydrated castor oil.
