Abstract: 447,157. Table games. COOLEY, H., 12, Crossway, Raynes Park, London. March 20, 1935, No. 8632. [Class 132 (ii)] In an apparatus for playing a game wherein a ball is projected up a board by means of a cue or by a spring-pressed plunger, means is provided whereby the ball, when returning after projection up the board is constrained to return only to its starting point, the said means however, permitting smaller balls used in the game to pass to other locations at the foot of the board. A supply of scoring balls are placed in an inclined shoot B the foremost ball resting in a retaining depression C to prevent the balls running running down to an exit K. A larger ball is placed in front of a spring plunger S. In playing the game the player starts a ball rolling down the shoot B and as it leaves the exit K projects the larger ball at it and endeavours to drive the smaller ball through one of the arches d into a scoring compartment E. An angular buffer F is arranged behind the compartments. The larger ball is too large to pass through the arches and returns by gravity to the spring plunger, being guided thereto by wire guides G, G1 arranged slightly above the board. If the smaller ball fails to enter an arch it runs beneath the guide G1 and enters one of the scoring pockets E1. If the player fails to hit the smaller ball as it issues from the exit K, the smaller ball passes into a receptacle E2.

Title: Improvements in or relating to the preparation of amido derivative of imidopolyphosphoric acids
IPC: C01B25/00
Filed: 1957-03-15
Abstract: An amide of an imido-polyphosphoric acid is produced by reacting dry hydrogen chloride with an amide of a phosphoric acid. At - 60 DEG  to + 10 DEG  C., with vigorous stirring, the triamide of ortho-phosphoric acid is converted to the tetramide of imido-diphosphoric acid, while a higher temperature, e.g. 30 DEG  C., gives the pentamide of diimido-tri-phosphoric acid, and at 180 DEG C. or more a mixture of amides of imido-polyphosphoric acids is formed.  The triamide of ortho-phosphoric acid may be subjected to the stream of dry HCl while suspended in ether, and the product is filtered, washed with dry ether, dried in vacuo over P2O5, washed with liquid ammonia to remove NH4Cl, and subjected to dry inert gas to remove excess NH3.

Abstract: 780,940. Annealing. ALLIS-CHALMERS MANUFACTURING CO. March 21, 1956 [March 23, 1955]. No. 8787/56. Class 72 [Also in Groups XXII and XXXI] A method of producing side bars for the track links of crawler tractors and the like comprises preforming the side bar as a steel body with a pair of transverse bores, through hardening said body in its entirety and tempering portions of said body surrounding said bores to render them more ductile than the remainder of the through hardened body. After forging, the side bar is normalized to a grain structure which is a ferrite with a pearlite matrix and then machined to final dimensions except for the pin and bushing bores 38 and 39. After machining, the bar is heated in a furnace to a temperature between 1300‹ to 2000‹ F. and then quenched in a water solution with 5 per cent caustic soda at a temperature of 120‹F. The side bar is then tempered between 600‹ and 850‹F. and allowed to cool in air. In order that the pin and bushing bores can be economically machined the portions of the side bar adjacent the bores are heated to a temperature above the previous tempering temperature by high frequency inductions coils 81, 82 (Fig. 10). to reduce the hardness in said portions. Some of the ductile bore portion remains after final machining and this facilitates press fitting over the bushing.
