IPC: E05B63/24
Filed: 1944-11-27
Abstract: 583,602. Automatic catches. WHITE & CO., Ltd., J. S., and SPILLER, H. O. Nov. 27, 1944, No. 23597. [Class 44] Two relatively movable parts are detachably connected together by a fastener comprising a headed projection mounted on one part which is engaged at a neck or reduced portion behind the head by two hook-like pivoted locking members mounted on the other part, provision being made for release by means of a pin-shaped member which is free to slide within the headed projection and can be protruded beyond the head of the latter to press the locking members apart. Two locking members J, Fig. 1, pivotally mounted at J<1> to a side wall H of a cupboard are urged together by a spring K to abut at surfaces J<4>, J<5>. When the cupboard door A is closed, tooth-like projections J<2> engage an annular recess B<2> behind the head B<1> of a projection B carried by the door. A spindle F free to slide within the projection B carries at its outer end a button F<1> which when depressed against the action of a spring G causes a boss F<2> to protrude from the head B<1> and open the locking members clear of engagement with the recess B<2>. The projection B is secured to the door A by being screwed into a handle D, and a bush C of rubber or other resilient material serves as a shock absorber. In Figs. 5 and 7, the members J are carried between plates L, L<1>. Plate L carries at its inner side two lateral projections L<2> serving as stops to limit inward movement of the members J. The projection B may be in the form of a sheet metal pressing B<4>, Fig. 9, the sliding boss F<6> being stamped from flat strip. The release button may be mounted at a distance from the sliding boss and connected thereto by a lever.

Abstract: 748,188. Sliding bolts. HOLDEN & CO. (B'HAM), Ltd., E., and HOLDEN, E. J. Aug. 27, 1954 [Aug. 27, 1953], No. 23656/53. Class 44. A lever action bolt fastening comprises an actuating lever 14, one arm 141 of which has a sliding and pivotal association with a slidable bolt actuating means 11 in a manner such that movement of the lever 14 from one or other of its extreme positions to the opposite extreme position effects a positive shooting or withdrawal of the bolt (not shown) according to the direction of movement imparted to the actuating lever and spring means 16 which acts directly on the actuating lever in a manner such that the said spring means is stressed whenever the actuating lever is moved from one or other of its extreme positions to the opposite extreme position whereby after the actuating lever has passed the deadcentre position the energy stored in the spring means due to the previous movement of the actuating lever is released to urge the actuating lever towards and subsequently to tend to retain the actuating lever in the extreme position to which it has been moved and additional spring means 17 which tends at all times to maintain the bolt actuating means 11 in sliding relationship relatively to a mounting 10 therefor and which is associated with the directly acting spring means 16 in a manner such that the additional spring means 17 also is stressed whenever the actuating lever is moved and the energy thereby generated and stored utilised on release to supplement the action of the directly acting spring means 16. The bolt is attached by a rod 111 to the actuating means 11 which is slidably mounted between the sides of a housing 102 forming part of the mounting 10. The lever 14 is fulcrummed in the sides of the housing by screws 13 and projects through a slot 101 in the mounting 10. The arm 141 of the lever 14 is bifurcated to embrace the means 11 and it is connected to the means 11 by a pin 15 which joins the jaws of the bifurcated arm and which pivotally and slidably engages a slot 113 in a boss 114 on the means 11. The spring means 16 is trapped between the end of the arm 141 and projections 115 on the end of the boss 114. One end of the spring means 17 is fixed to the mounting 10 and the free end engages the means 11 and is maintained in contact with it by a pin 18 on the mounting 10. An intermediate position of the spring means 17 engages the boss 114.

Filed: 1927-09-08
Abstract: 299,152. Imperial Chemical Industries, Ltd., Pope, R. W., and Wyler, M. Sept. 8, 1927. Azine and sulphuretted dyes.-Oxy-phenazines, naphthophenazines and dinaphthazines are treated with an alkali bicarbonate, or with carbon dioxide in the presence of alkali. Oxycarboxyazines are produced which on thionation yield sulphur dyestuffs. In one example, the sodium salt of an azine having the formula is heated with aqueous sodium bicarbonate under pressure. The resulting oxycarboxyazine, on treatment with sodium polysulphide in the presence of copper sulphate gives a reddish brown sulphide vat dye. According to a further example, the sodium salt of the oxyazine used in the first example is freed from water by heating in vacuo and is then treated with carbon dioxide under pressure. The product, on thionation, yields a similar sulphuretted dyestuff.

Title: Production of finely divided titanium dioxide
IPC: C01G23/07
Filed: 1950-10-06
Abstract: Pigmentary rutile titanium dioxide is produced by decomposing at 1000-1600 DEG C vaporized titanium chloride with gases containing free oxygen in the presence of a volatile silicon compound and a volatile aluminium compound in amounts sufficient to yield a product containing 0.01-5 per cent silica and 0.01-5 per cent alumina produced by decomposition.  The ratio alumina/silica should be in the range 3-1 : 1.  Suitable aluminium compounds are the halides or trimethyl aluminium.  Silicon compounds are silicon-tetra-or-hexachloride, -tetrabromide, -chloroform, or -tetraethylester, chloro-methylsilicane, dimethylsilicane, tetramethyl silicane, silicon hydride &c.  The aluminium and silicon compounds may be added to the liquid titanium chloride to be vaporized, e.g. by bubbling oxygen therethrough; alternatively, aluminium chloride may be separately sublimed, e.g. by passing chlorine, with or without diluent gas, over aluminium shavings or a mixture of alumina and carbon, or carbon monoxide and chlorine, or phosgene, over alumina, the vapours being added to the titanium chloride vapours.  The titanium chloride should be mixed with at least 50 per cent, up to a surplus, of oxygen for its decomposition. Inert gas may be present.  The reaction mixture should be heated above 135 DEG C, up to 500 DEG C.  The feed rate should be 1-50 metres/sec.  Decomposition is effected in the presence of an auxiliary flame produced by burning methane, acetylene, hydrogen &c., or, preferably, carbon monoxide.  Examples disclose burners consisting of concentric tubes, the titanium chloride mixture supply tube being surrounded by, and in some cases also surrounding, the supply tubes for the auxiliary flame-producing gases.  The product may be subjected to evacuation to remove chlorine and hydrochloric acid, and neutralized with a small amount of lime.  Specifications 567,093, 661,685, 673,782, 686,568 and 686,570 are referred to.

The shank piece carries sewing lips at the waist and a metal inset at the heel to prevent heel nails coming through. A recessed press tool is provided in which the shaped elements can be pressed and cemented together preferably by a celluloid solution. An insole 1, Fig. 8, has a sewing rib 7 attached thereto by a waterproof cement. The sewing rib may be of various forms and may consist of a thick leather strip 6, Fig. 5, split at the base and cemented to the insole 1, or the rib may be L-shaped or two L-shaped pieces may be placed back to back. When the insole is channelled as in Fig. 3, a lip 2 is reinforced by a cemented strip 3, the top edge of which may be afterwards curled over to cover stitching. The strips may be in one or more pieces. Combined with the insole is. a shank piece 12. Figs. 8 and 9, channelled at 15 to provide a sewing lip. The edge 14 of the shank piece is set back at the waist to form a recess for the reception of the upper. Before the shank piece is cemented to the insole a horse-shoe shaped metal strip 13 is connected to it so positioned that heel nails will be clenched against it and prevented from penetrating the insole. In a modification, Fig. 13, the edges of the shank piece are sloped and sewing lips 17 are cemented thereto. The edge of the insole may be channelled at the waist and an edge turned up and cemented down again to cover nailing. The insole can also be shaped to the foot by triangular sticks cemented to either side of the insole, presenting a concave supporting surface to the foot. Triangular strips 8, Fig. 14, may be cemented to the insole 1 inside the sewing lips after the attachment of the upper. In a modification, a similar strip 10, Fig. 15, may be cemented to the top side of the insole. These strips 10 are cemented in position after the attachment of the outer side so as to cover the fastening means. The attachment of the sewing lips and shank piece is by means of a press tool, Fig. 19, capable of fixing the elements in their relative position. The tool consists of a block 18 recessed at 20 to take the shank piece and insole and grooved at 19 to receive the sewing lips. The parts are placed in position and cemented with celluloid solution and pressed with a cover. The tool may. be made adjustable in known manner by longitudinal division with screw-adjusting means.

Abstract: 936,645. Electric selective signalling systems] AMP Inc. June 27, 1962 [July 6, 1961], No. 24646/62. Class 40 (1). [Also in Group XXXIX. A decoding tree using magnetic cores transfers the set state of core 30 to the one of cores 32 and 34 corresponding to the first binary digit of an input signal and then to the one of cores 36, 38, 40 and 42 which corresponds to the two bit input signal. In the embodiment of Fig. 2, core 30 is first set by source 44. The first bit of a signal from source 112 then sets phase sensitive amplifier 106 or 110 depending on the binary digit and also causes timing circuit 114 to set odd to even transfer source 92. If the first bit is " 1 " amplifier 110 is set, sending a current through transfer control cores 58, 74 and 66. On the passage of the pulse from source 92 an output signal is produced in windings 52 and 56. The signal in winding 52 sets control core 54 and then has insufficient strength. to set core 32. Because of the signal in winding 108 core 58 is not set by the output signal in winding 56 and the set state of core 30 is transferred to core 34. The second digit of the output signal sets source 96 which transfers the state of core 34 to core 40 or 42 depending on which of amplifiers 106, 110 is set. Source 92 may then be used to transfer information to output circuits 78, 82, 86, 90. The cores are primed at each stage either by the clearing current flowing to ground through winding 100 or, in the case of core 32 after being set by source 44, by source 102 which also clears the transfer control cores 54, 58, 64, 66, 72 and 74. In the embodiments of Figs. 3 and 4 (not shown), inhibit windings are used instead of the transfer control cores.
