Title: Improvements in or relating to flushing cisterns
IPC: E03D1/14
Filed: 1948-03-25
Abstract: 647,092. Syphon-discharge water-waste-pre venters. MAGUIRE, F. C. March 25, 1948, No. 8741. [Class 26] In a flushing cistern of the kind having two handles. one producing full flush and the other partial flush, and having a valve-controlled air inlet in the syphon operated by the appropriate external handle, the air admission valve is maintained closed by a weighted lever movable by a handle to permit opening of the valve. As shown, applied to a low level cistern, the upward leg 33 of a syphon has an air inlet 41, above the normal water level, closed by a valve mounted on a leg on a float 43. The float 43 is mounted on an arm 47 pivoted at 48 and carrying at its other end a bucket 50 having a lateral flange 51 and normally below the water level. Operation of the full-flush lever 25 causes complete discharge of the cistern, the valve being kept closed by the weight of the full bucket 50 acting through the arm 47. On operation of the partial flush lever 35, the bucket 50 is raised, by the action of an arm 40 and pin 52, above the water level and emptied; at the same time syphonic action is started. When the water level has reached a predetermined value the upthrust on the float is insufficient to maintain the valve in the closed position, the syphon is broken and the discharge stopped. The partial flush lever may be mounted on a shaft co-axial with the full flush lever and weighted to be normally in a different angular position from that of the full flush lever. The bucket may be arranged to be filled slowly on being water-borne. The air inlet may be below the normal water level and the partial flush lever operate first to open the valve and then to initiate flush. When applied to high level cisterns, two crank arms may be fitted, the partial flush handle slipping over the chain or rod of the full flush handle. The partial discharge handle may carry a counter weight to operate only when the handle is manipulated with sufficient energy to operate the syphon. The Provisional Specification also states that in the case of a low level cistern the bucket may be so designed that its inner side wall becomes horizontal after the rocking lever has moved through about 45 degrees.

Patent GB-734050-A (GB)
Title: Process for the production of amino alcohols
IPC: C07C213/00
Filed: 1953-03-31
Abstract: Amino alcohols are prepared by hydrolysing a chlorinated alkyl amine hydrochloride by heating in water whilst maintaining an acid reaction.  The hydrolysis may be effected by heating under reflux or under pressure with 5 to 100 times the quantity of water. Reaction temperature may lie between 50 DEG  and 200 DEG  C. and reaction times of 1 to 20 hours are required.  The free amino alcohols are recovered by addition of a strong base such as caustic soda, caustic potash or lime water followed by distillation which may be carried out under vacuum, or the hydrochloric acid formed may be distilled off before adding the strong base.  Small amounts of alkenyl amines and amines containing two hydroxyl groups or a keto group, are formed as by-products.  The amino alcohols may be used for the production of alkyd resins or other polymerization products.  In examples: (1) n-butylamine was neutralized with hydrochloric acid and chlorinated whilst being irradiated with ultra-violet light.  The hydrochloric acid formed was distilled off and the residue hydrolysed with water at 150 DEG  C.  The free base was obtained by addition of caustic soda and 4-amino-butanol was recovered by distillation; (2) n-pentylamine in carbon tetrachloride solution was neutralized with hydrogen chloride, then chlorinated while using actinic light.  The solvent was distilled off and the residue hydrolysed and worked up as in (1). The product was 5-amino-pentanol; (3) n-hexylamine was converted to hydrochloride and chlorinated as in (2) and the residue refluxed with water.  The product after neutralization and distillation was 6-amino-hexanol; (4) 5-chlor - 1 - amino - pentane hydrochloride was hydrolysed with water at 150 DEG  C.  The residue was worked up as in (1) and the product was 5-amino-pentanol.

Patent GB-292092-A (GB)
IPC: G07F17/38
Filed: 1928-03-26
Abstract: 292,092. Walzer, A. M., and Lagaard, A. S. T. June 13, 1927, [Convention date]. Table games.-A game apparatus comprises a field member with a surface sloping towards a common point remote from a plurality of holes, a striking manikin for propelling a ball on the field member and means for varying the direction in which the striking manikin operates to cause the ball to be propelled selectively in the direction of any hole. Enclosed within a glazed casing is a field B, Fig. 1, simulating a golf course with a tee 33, three greens 34, 35, 36, bunkers 48 and a lake 53. A manikin C, representing a golf player, may be actuated by means of external handles 46, 47 so as to strike miniature balls into holes 37, 38, 39, 54. In commencing a game, a coin is inserted into a slot 142 whence it descends into a coin holder 135, Fig. 4, secured to a slidable rod 44 manipulated by an external knob 134. On pressing-in the knob the coin presses against the end of a rod 138 and moves the same longitudinally. The rod 138, operating through a bar 145, rotates a curved plunger 162 working in a curved receptacle 122 within which the balls, previously projected through the holes in the greens, have accumulated. The balls are thus raised to a depressed portion 121 when they run down a shoot and accumulate in a pocket 45, Fig. 1. Balls projected into the hole 54 in the lake run directly into the pocket 45. The knob 134 is retracted by a spring and during the rearward movement the pressure of the coin against the rod 138 is relaxed thus allowing the coin to fall through the coin holder into a receptacLe 144. Owing to a hole 141 in the coin holder opposite the rod 138, the absence of a coin prevents further operation of the ball-issuing mechanism. The balls in the pocket 54 may be pushed out one at a time as required so as to roll on to the tee 33, by pressing in the knob 134 thus causing the rod 44 to push back a lever 155 and raise a hooked finger 151 behind the foremost ball. The manikin C is secured to a revoluble platform 57, Fig. 5, and is recessed at the back and front to receive a vertical rod 69, and a cranked rod 64 terminating in a golf-club portion 43. The rod 69 is normally retained in the lower position shown by a spring 103. When the player depresses the handle 47, a link 100 connected thereto actuates a bellcrank lever 106, 104 and raises the rod 69 to produce a striking movement of the club 43. The direction of the stroke is controlled by the handle 46 which has a link connection 89, 90 with the revoluble platform 57.
