Filed: 1971-06-21
Abstract: 1393677 Gas cutting BRITISH OXYGEN CO Ltd 21 June 1972 [21 June 1971] 28987/71 Heading B3V An electrical control circuit in a gas fuelled cutting machine includes a first relay RLC/2 for controlling the supply of cutting oxygen to the cutting nozzles of the machine and a second relay RLB/2 for controlling the supply of high intensity preheat gases, a contact RLC1 of the first relay RLC/2 in its unenergized state being in circuit with a contact RLB1 of the second relay RLB/2 whereby when the cutting oxygen relay RLC/2 is energized the high intensity preheat gas relay RLB/2 is de-energized if previously energized. The cutting of a workpiece is initiated by depressing a switch S1 to bridge contacts 12 and energize a relay RLH/2 causing its contacts RLH1 and RLH2 to be actuated, the latter actuating solenoids 18, 20 for supplying low intensity preheat gases to the cutting nozzles. The contacts of the relay are of the type that remain closed when the switch S1 is released. The preheating of the workpiece is increased by pressing a switch S3 to energize the relay RLB/2 and close its contacts RLB1 and RLB2, the latter actuating solenoids 14 and 16 for supplying high intensity preheat gases to the nozzles. When the workpiece is preheated, a switch 52 is depressed to energize a relay RLC/2 and actuate its contacts RLC and RLC2, the latter actuating a solenoid 24 for supplying cutting oxygen to the nozzles. Upon actuation of contact RLC1, the circuit to contact RLB1 is broken causing the relay RLB/2 to be deenergized and the solenoids 14 and 16 to be deactuated. The high intensity preheat gases can be turned on at any time by pressing the switch S3 to override the relays. The supply of cutting oxygen or high intensity preheat gases is stopped by depressing the switch S1 which deenergizes the relay RLC/2 or RLB/2. The supply of all preheat gases and cutting oxygen is stopped by depressing a switch S4 which causes de-energization of all the relays and actuation of solenoids 22 and 26 for venting the fuel gases and oxygen from the nozzles.

Abstract: 167,704. Denny, M. E. Oct. 16, 1920. Door holders; operating doors by toothed-gear mechanism. - Bulkhead and like sliding doors are held in the open position by a collapsable linkage in the form of toggle levers forming a strut and engaging a detent on the door or associated with the door-opening mechanism, the linkage being movable either locally or from a distant control into a position in which it collapses under the weight of the door, which then closes. In the arrangement shown, the bulkhead A is opened by a rack and pinion B, C through bevel-gearing D<1>, E<1> rotated by the shaft E. In this position, a detent lever F<1> being pivoted at G<1> to a link G supported by rollers G<3> on a track H. As shown in Fig. 3, the links have been set by hand into a locking position, the link G contacting with stops J, J<1> and the parts being maintained in this position by the thrust transmitted by the weight of the door, and by springs K<1>, G<4>. To release the door, the link G is moved along the track H into a position in which the link members collapse by the weight of the door. The detent wheel D<2> is then free to rotate and the door to fall into its closed position, the links taking up the position indicated by chain lines, and being stabilized in this position by the spring G<4>. In repositioning the link G, the pin J<1> acts as a fulcrum about which the link moves during the initial part of its travel.

Abstract: The process of the parent Specification which comprises contacting an alkali metal silicate solution having a silica to alkali metal ratio of 3 : 1 to 3,4 : 1 with sulphuric acid in an amount sufficient to form a silica hydrogel, commingling with the resulting mass an aluminous slurry containing Al2(SO4)3 and unreacted Al(OH)3 in which the mol ratio of SO4 to Al2O3 is less than 3 : 1 in an amount sufficient to provide up to 50% active Al2O3 in the final catalyst, adding a basic precipitant to the slurry to complete precipitation of the Al2O3, and purifying and drying the resultant product, is modified in that at any stage during the process prior to drying clay is added in a proportion constituting at most 50% by weight of the final product.  Preferably the alkali metal silicate is Na2SiO3 and the clay is Kaolin.  The aluminous slurry may be formed by either reacting Al(OH)3 with less than the equivalent quantity of H2SO4 or by adding Al(OH)3 to a N/1 Al2(SO4)3 solution.  In a modification of the process the mol ratio of SO4 to Al2O3 is decreased below 3 : 1 by the addition of part of the Al(OH)3 at any stage in the process prior to drying.  Comparative examples are given.
