Title: Improvements in or relating to locks for the doors of safes, strong rooms, and the like
Inventor: RATCLIFF CHARLES MILNER
IPC: E05B65/00
Filed: 1953-03-11
Abstract: 770,431. Safes. RATNER SAFE CO., Ltd. March 8, 1954 [March 11, 1953], No. 6738/53. Class 44. Auxiliary locking means for the doors of safes, or strong rooms, comprises a spring-urged sliding bolt positioned to engage, or be released for engagement with, the main looking means of the door on the violent disturbance of the door or the main locking means, the sliding bolt also being locked when engaged with the main locking means. In Fig. 2 the auxiliary locking means comprises a housing 10 with a sliding bolt 9 biased by a spring 11 and restrained by tie rod 13 or thrust rod 16. In its fully shot position bolt 9 is locked by a spring-pressed plunger 18 entering a recess 20 in the housing 10. Various arrangements of these bolts are shown in Fig. 4 which shows a safe door with four main locks 40, 41, 42, 43, controlling bolts 44 on the bolt bar 45. The tail 69 of bolt 67 of lock 40 supports the auxiliary bolt 65 by rod 68 and the two bolts normally slide together, bolt 65 being held above its locking position ; but should lock 40 or rod 68 be removed by a violent disturbance bolt 65 is shot into its locking position blocking bolt tail 70. Similarly auxiliary bolt 66 is restrained by tie-rod 71 and lever 72 engaging projections 74 on the lock case 40 and breaking or removal of any of these parts causes bolt 66 to lock bolt tail 75. Should lock 41 be maltreated the supporting bracket 63 may be damaged, thereby releasing rod 62 and auxiliary bolt 61: Similarly lock 42 has bolts 54 and 55 dependent on its look case while lock 43 is closely bridged by a fragile member 48, see Fig. 5, retaining auxiliary bolt 51. Auxiliary bolt 78 is restrained by a tie-rod 83 extending the length of the door and should this be cut the bolt is released to block bolt tail 53. Similarly bolt 77 depends on tie-rods 79 and 81 connected to fulcrum plate 80 so that any attempt to cut bolt tail 82 releases bolt 77 to block bolt tail 47. Auxiliary bolts may also be arranged in opposition with a common tierod between them (see Fig. 3, not shown). Any of the members restraining the auxiliary bolts may be of a fragile or readily frangible material breaking readily under mechanical stress or melting readily on the application of heat.

In tea-making apparatus wherein water is automatically delivered on boiling, the boiling vessel is mounted on a lamp housing at least partly constructed of light transmitting material. As shown, Fig. 1, the lamp 7 is mounted centrally in a translucent sleeve of synthetic plastic, e.g. polymethyl methacrylate disposed between the kettle 2 and the base 3, the whole being bolted together. Alternatively, the housing may be of metal with windows. The kettle lid is secured by a bayonet fitting and has a vent hole 22. The kettle heating element 16 is controlled by a switch 13 actuated by a spring-loaded member 23, 24 which forms one of the base feet so that switch 13 is closed when the kettle is filled. An audible alarm 15 is provided which is shorted when switch 13 is closed. In operation, with a manual switch 14 off, the kettle 2 is filled with water. When the tea is required, switch 14 is closed and the water is heated until it boils when the pressure syphons it through spout 26 into a tea-pot containing tea leaves placed at the side of the apparatus. The apparatus is then rocked forward as switch 13 opens, buzzer 15 sounds and the circuit to lamp 7 is closed. When switch 14 is turned off, buzzer 15 stops but lamp 7 stays on until the kettle is refilled. In a modification, Fig. 4 (not shown), a vessel consisting of two compartments forming the kettle and a tea-pot is mounted on the translucent sleeve. In a further modification, a separate kettle and tea-pot are joined together and mounted on the translucent sleeve.

Title: Clarification of aqueous organic suspensions
IPC: C02F1/54
Filed: 1957-03-01
Abstract: Aqueous suspensions of finely divided organic solids are clarified by incorporating in the suspension at least 0,01 pound (per short ton of suspended solids) of a water-soluble sulphonate (i.e. a sulphonic acid or salt thereof) derived from a high molecular weight poly (vinyl-aromatic) compound of the benzene series to increase the rate of sedimentation of the suspended solids.  The aqueous suspension may be a waste water which must be clarified before discarding or reuse, and may be derived from a cannery, a sugar refinery or coal-washing plant.  The sulphonates may be derived from polymers of stryrene, alpha-methyl styrene, vinyl toluene or vinyl xylene, or from linear copolymers of such materials with one another or with acrylic monomers (i.e. acrylonitrile, methacrylonitrile or the lower alkyl-esters of acrylic or methacrylic acid.  Ammonium, lithium sodium, potassium and calcium salts of the sulphonic acids are mentioned.  The sulphonates may be added to the aqueous suspensions in the form of aqueous solutions or they may be introduced as a finely divided solid in admixture with a finely divided inert solid. Before the sulphonate treatment, lime (in the form of finely divided calcium hydroxide or oxide, milk of lime or calcium hydroxide solution) may be added to the aqueous suspension.  In the examples, (a) an aqueous slurry of coal fines from a coal crushing and cleaning milk, or a limed aqueous waste slurry of pea soup solids from a soup cannery, is treated with the sodium salt of the sulphonic acid derived from polyvinyltoluene or vinyl-toluene/acrylonitrile copolymer, (b) the aqueous slurry of coal fines is treated with free polyvinyltoluene sulphonic acid and (c) waste water from a beet sugar refinery is limed and treated with the sodium salt of polyvinyltoluene sulphonic acid or the potassium salt of polystyrene sulphonic acid.
