Title: Improvements in or relating to sprinkler heads for automatic sprinkler systems
Inventor: ALLEN GEORGE
IPC: A62C37/12
Filed: 1961-05-01
Abstract: 948,099. Sprinkler heads. MATTHEW HALL & CO. Ltd. July 19, 1962 [May 1, 1961], No. 15748/61. Heading A5A. A sprinkler head of the type in which a water outlet bore is closed by a valve member supported by a fusible strut which releases the valve member on a rise in ambient air temperature, includes in conjunction with the valve member a sealing member of synthetic thermoplastic material, e.g. polythene, polyvinyl chloride, nylon, polytetrafluoroethylene &c. The bore 4 is closed by a boss 12 projecting from a valve member 10 and the sealing member 6 is held in position by a washer 8 which, through a spring washer 9, bears on a shoulder 13 of the valve member 10. The closure means is held in position by a fusible strut 11 arranged between the valve member 10 and yoke arms 2. A rise in ambient temperature will operate the fusible strut 11, whereon the water pressure in the bore will force out the valve assembly, the ejection being facilitated by a slight divergence 5 at the outlet of the bore. As the sealing member 6 is made of a synthetic plastic it is possible for the force on the fusible strut 11 to be reduced.

Abstract: 1,068,882. Photo-sensitive materials. MINNESOTA MINING & MANUFACTURING CO. April 21, 1964, No.16571/64. Heading G2C. A photo-sensitive composition comprises (1) a photo-sensitive heavy metal salt which can be reduced to the free metal by exposure to radiation of wavelengths less than 1 micron and (2) a non-photo-sensitive oxidation-reduction combination consisting of an organic silver salt and an organic reducing agent which is capable of being initiated by the free metal to produce a visible change on self-initiation or by water, an ionisable organic solvent or by heat at a temperature at. which the combination alone does not react, the metal salt being present as a minor amount. Specified metal salts are those of copper, chromium, cobalt, platinum, gold and silver and preferably a silver halide, silver sulphinate or a metal diazosulphonate. The organic silver salt of the combination may be silver saccharin, silver 5-chloro- or 5-nitrosalicylaldoxime or silver behenate.

Filed: 1962-05-01
Abstract: 971,722. Dispensing articles on conveyers. PORT OF LONDON AUTHORITY. July 25, 1963 [May 1, 1962], No. 16716/62. Apparatus for sorting and tallying mixed cargo discharged from a ship at a quay 10 comprises a conveyer system 12 having a row of closed loop sections 16 which may be fed from hoppers 14. The individual sections 16 are interconnected by conveyers 17, and each section has diverting means, e.g. a guide located as at positions 18, for diverting items of cargo to receiving stations. The diverting guides are remotely actuated, from positions alongside the conveyer loops, by an automatic control panel. Alternatively, by operating one of a number of parallel connected button switches, a guide is moved into the diverting position. Each button is identified with a specific type of item of the cargo by an interchangeable label and has an associated counting mechanism. This mechanism has a locking device which prevents further actuation of the button after a predetermined number of operations appropriate to the number of items represented by that button required to make up a load. Before unloading starts each control panel is prepared so that the desired composition of cargo will be directed to each receiving station. An operator depresses the appropriate button as each desired type of item approaches the diverting guide controlled by his panel. A light signifies completion of the load and a tally of the number and type of items is printed by actuation of a further control panel button. In Fig. 3, the apparatus comprises a sorting conveyer 110 and discharge shoots 111, each shoot being associated with a punched card controlled diverting mechanism 114, a registering station 115 and a monitoring device 116. The conveyer 110 is a series of linked trays identified by colour into repeating groups of four, e.g. successive trays are coloured red, yellow, blue, white, red &c. The registering station 115 comprises four similar panels 121 with a series of buttons, each button producing distinctive electrical pulses which are fed into the monitoring device 116. The different pulses form coded representations of the different items of cargo, each item being coded by pressing of the appropriate buttons, and recorded in a central bank. Each diverting mechanism 114, when activated, ejects the cargo from the tray just passing into its shoot 111. The diverting mechanism is activated by a punched card controlled machine. A consignee has his requirement transposed on to a punched card which is fed into the machine at a vacant shoot. Thereafter, such items as are required are diverted into the shoot until the consignment is made up. A counting mechanism in the punched card machine stops operation of the machine when the desired load is made up.
