Title: An improved construction of game apparatus
IPC: A63F7/02
Filed: 1925-04-18
Abstract: 238,493. Wells, C. H. April 18, 1925. Table games.-Apparatus for playing a bagatelle game comprises a board 1 divided into a number of spaces 2 by guide strips 3 into any one of which a ball may be directed by a series of pins 5. Hinged flaps 14 disposed in the spaces 2 have upward projections 15 marked with numbers representing score-values, said projections being lifted through a slot in the cover board and thereby made visible by the passing of the ball. The board is arranged in a sloping position and the ball is projected from its lower end by a spring plunger 7 to the upper end, from which it returns by gravity. The individual scores are totalized by a disc 21 provided with radial projections 24 towards which the ball 4 is directed by rows of pins 17, the disc being turned thereby through an arc corresponding to the score-value. A pointer mounted in the spindle 23 of the disc registers with a graduated circle marked on the surface of the cover board. The disc is prevented from rotating too far by the ball itself, which comes in contact with a block 20 on the plunger and acts as a stop. One or more pivoted flaps 8 carrying a figure 9 may be arranged in the path of the ball, which in passing causes the figures to project through apertures in the cover board.

Title: Process for the polymerization of conjugated dienes
IPC: C08F36/04
Filed: 1963-03-14
Abstract: Conjugated dienes e.g. butadiene or isoprene are polymerized in the presence of a catalyst which consists of a Co and/or Ni compound with AlX3 (where X is a halogen) and a Si compound of general formula SiHxY(4-x) where x=1, 2 or 3 and Y is a hydrocarbon radical or a group SiRzH(3-z) in which R is a hydrocarbon radical and z=0, 1, 2 or 3.  Polymerization is preferably effected in the presence of a hydrocarbon solvent e.g. benzene or isooctane. When butadiene is polymerized according to the above procedure the result is almost entirely 1:4 polymerizations.  Isoprene produces a little 3:4 polymerization in addition to 1:4. Examples are given. Specifications 904,404 and 946,179 are referred to.ALSO:A polymerization catalyst consists of a Co and/or Ni compound with AlX3 (where X is a halogen) and a Si compound of general formula SiHxY(4-x) where x=1, 2 or 3 and Y is a hydrocarbon radical or a group SiRzH(3-z) in which R is a hydrocarbon radical and z=0, 1, 2 or 3.  Preferably the Co and/or Ni compound is a salt of an organic acid, e.g. nickel naphthenate.  Alternatively Co and/or Ni halides may be used as complexes with amines, alcohols or ketones.  The preferred aluminium halide is AlCl3, but AlBr3 may also be used. Specified Si components include silicon trimethyl hydride, silicon triethyl hydride, silicon diethyl dihydride, silicon tributyl hydride, silicon diphenyl dihydride, pentaethyl disilane and 1 : 1 dimethyl silane.  Examples are given.  Specifications 904,404 and 946,179 are referred to.

Patent GB-631135-A (GB)
Title: Improvements in and relating to screen printing apparatus
IPC: B41M1/12
Filed: 1947-04-16
Abstract: 631,135. Stencilling-apparatus. WALKER, D., and EVANS & CO., Ltd., D. April 16, 1947, No. 10148. [Class 100 (ii)] A screen printing-apparatus comprises mechanical lifting means for raising a screensupporting frame diagonally from a support cornerwise and progressively to break the adhesion between the screen and the materials being printed after a printing impression has been made, without undesired disturbance of the material on the support. As shown, the screen and framework 2, 3, 4 are attached to a rear channelshaped member 80 forming a carriage having a pair of grooved rollers 85 which travel along a table rail 86 and form a hinge about which the whole carriage may be raised, the location of the carriage along the rails into each pivoting position being determined by a stop 109 and a pair of sockets 113. The stops and sockets are adjustably secured to the rails 86. The mechanical lifting of the carriage is effected by moving roller-carrying levers 81- 82, Fig. 5, about pivots 83, 84 by means of small links 105, 106a and 105, 106 respectively, which are operated by rods 104, Fig. 1, extending from the front of the machine where they are connected by a pair of parallel levers to an operating-handle 102. Downward pressure on the handle 102 will thereupon immediately cause the rear right-hand corner of the stencil to rise, but due to the lost motion of a slotted connection 107, the lifting of the left-hand corner is delayed. The carriage is locked in the raised position by a catch 119, Fig. 7, engaging a recess 115 in a block 89 forming a coupling between the two levers 81, 82. Block 89 has a pin 93 rising through the carriage to form part of a spring assembly which gives a cushioning to the carriage when a pin 90 depending from the block 89 drops into a locating slot 108 in the stop 109. After the initial raising and sideways travel of the carriage, the higher corner of the carriage is lowered to bring it level by the engagement of a lever 130 with an end part 133 of the stop 109. Lever 130 has a slot 128 through which projects a pin 127 mounted on an eccentric boss 125 forming the bearing 84 of the lever 82. An elongated bearing hole 124 for the boss 125 is provided in the lever 82 so that when the lever 130 is rotated by engagement with a stop 109 the anticlockwise movement imparted to the pin and boss permits the carriage to fall relative to the lever 82. When the next printing position is approached, a lever mechanism 134, 120 having been lowered by the action of lever 130, engages the next stop 109 releasing the block 89 and the pin 90 slides down a slope 135 until finally located in the slot 108. During the reverse travel of the carriage, lever 134 and lever 130 are ineffective since clockwise movement of the former will not actuate the catch 119 and similar movement of lever 130 will not rotate the eccentric disc since the pin 127 rides freely in a slot 128 in the lever. The construction and operation of the squeegee is described in Specification 625,108.

Title: Improvements in or relating to nut or screw connections
IPC: F16B39/36
Filed: 1929-04-02
Abstract: 312,632. Ryck van der Gracht, F. M. P. de. May 29, 1928, [Convention date]. Locking nuts. - A lock-nut is formed in two parts with a conical engaging surface between them so that the inner portion is forced to grip the threads of the bolt firmly when the nut is screwed up. The inner portion 1 is made resilient bv a longitudinal split 3, and closely fits the conical bore of the external hexagonal nut 2. Relative rotation between these parts is prevented by the pin 5 sliding in longitudinal grooves which are formed at a short angular distance from the split 3. When the nut is screwed up to its work, the conical shape of the part 1 causes the threads on its inner surface to grip the bolt firmly whilst any rotary motion in the direction of unscrewing is prevented by the pawl-like action of the longer arcuate portion of the part 1, i.e. from the split 3 to the pin 5, in the direction of unscrewing.

Title: Improvements in or relating to braking systems for aircraft
Inventor: TREVASKIS HENRY WILLIAM
IPC: B60T8/74
Filed: 1950-04-29
Abstract: 683,490. Fluid-pressure brakes. DUNLOP RUBBER CO., Ltd. April 25, 1951 [April 29, 1950], No. 10597/50. Class 103 (i). A device for preventing the application of fluid-operated wheel brakes for aircraft before the landing-wheels rotate on touching down, comprises a bracket 101, Fig. 1, secured to a non-rotatable portion of a wheel and brake assembly, a fly-wheel 102 provided with tyres 15 adapted to contact the inner periphery of a landing-wheel rim, and centrifugal arcuate-shaped members 47 pivoted at their ends to the fly-wheel, Fig. 8, provided with light springs 48, and adapted to release a spring-loaded rod 45 operating inlet and exhaust slide valves 64, 76, Figs. 4, 5, controlling the fluid flow to the brakes via conduit 60. When the aircraft comes in to land the undercarriage is operated by fluid jacks (not shown). Pressure-fluid flows into the extension side of the jack and also into the cylinder formed in the nozzle 81, forcing the plunger 84 upwardly against compression spring 86 to turn a ratchet-wheel 87. An arm 54 in a chamber 44 of the valve body 58 is thus caused to rock, and move also an arm 62 in a separate chamber 56. The rocking of the arm 62 closes the inlet valve 64 and opens the exhaust valve 76 to the brakes. A leaf-spring 89, Fig. 1, ensures that the ratchet-wheel 87 will rotate in one direction only. The pivoting of the arm 54 also moves the operating rod 45 against the spring 50 to the left from the Fig. 1 position, causing the annular head member 46 to force the pegs 47 outwardly against springs 48. As the member 46 moves past the pegs they are returned inwardly to hold the rod 45 in the " cocked " position with the brake inlet valve 64 held closed. As the aircraft touches down the wheels rotate the fly-wheel 102, causing the centrifugal releases 47 pivoted thereto to move outwardly against the springs 48, thus allowing the members 46, 45 to move back under the action of spring 50 and open the inlet valve and close the exhaust valve so that brake pressure may be applied by the pilot. For static testing of the brakes the rod 45 may be moved manually by a rod 93 attached to a plunger 90 abutting the rod 45. The device described above may be used in conjunction with the automatic brake control described in Specification 676,708 which is referred to.

Sheets of paper or cardboard impregnated or coated with macrocrystalline paraffin wax are united by introducing a layer of microcrystalline paraffin wax between the sheets at the place where the sheets are to be united and pressing the sheets together while they are hot. The microcrystalline wax can be introduced by inserting a sheet or strip of paper coated or impregnated with the wax between the sheets to be united, or by spraying a layer of the microcrystalline wax on to at least one of the surfaces to be united. The sheets to be united may be coated with macrocrystalline wax on the inner surfaces only. The term " impregnated " includes saturated with liquid wax or having wax, e.g. in emulsion form, added to the fibrous mass from which the paper or cardboard is formed. Preferably, the ratio of the weight of microcrystalline wax per unit area of surface to be united to the total weight of macrocrystalline wax on a corresponding area of both sheets to be united lies between 0.5 and 2. The method may be applied to the manufacture of waxed paper bags, the microcrystalline wax being applied only to the places where the paper layers are to be united. The Specification also describes strips of paper coated, for test purposes, either with macrocrystalline wax or microcrystalline wax alone or with a mixture of the two kinds of wax in various proportions.
