Abstract: 1,225,590. Digestion of titanium ores. TITAN G.m.b.H. 28 April, 1969 [11 May, 1968], No. 21629/69. Headings C1A and C1N. Digestion of titanium ores with HCI of at least 35% strength is effected in stages in a continuous flow system of 2 or more seriesconnected reactors of high mixing intensity by passing ore and HCI co-currently (ore/HCl mixture temperature 25-60‹C.) into a first reactor, and thence into succeeding reactors at higher temperatures, the overall temperature range in the reactors being 65-105‹ C., and then withdrawing the digestion solution together with solid residue, from the last reactor. The reactors may be a cascade of stirred kettles and total dwell time is not more than 4 hours. The initial ore/HC1 mixture may be heated to 25-60‹ C. by passing it through a heat-exchanger which may be heated by digestion solution from the final reactor. The heat in each reactor derives from the exothermic TiCl 4-  forming reaction, and the temperatures in the reactor system are stabilized by adjusting flow of reactants. The digestion solution is further processed by removal of solids and by precipitation of FeCl 2 .4H 2 O before hydrolysis to TiO 2 .

Abstract: 1,228,712. Ticket issuing machine; totalizators. BELL PUNCH CO. Ltd. 5 June, 1968 [7 June, 1967], No. 26243/67. Headings G4A and G4T. A totalizator includes a central processor and a plurality of ticket issuing machines, each ticket issuing machine having a keyboard to make a first and second selection, a printing mechanism for printing the two selections, means for storing the first selection, and means for delaying completion of the printing until the selections have been recorded in the central processor, and the central processor having means to scan the ticket issuing machines sequentially, means to record the selections from a scanned machine, and means for checking the validity of the two selections and controlling the recording means of the central processor and the completion of printing in the ticket issuing machine. When a key 30 of the ticket machine is depressed a corresponding switch 32 is opened and a signal, corresponding to one of the selections 1-30, F, is sent along binary code lines 33 and also a parity check binary circuit line 33b if an even number of line connections from the key is made to the code line 33. The signals on lines 33 energize associated relays 34(1)-34(16) closing hold-on contacts 36(1)-36(16) and contacts 37(1)-37(16) in first transmission lines 38. As the key switch 31 is closed, a switch 40a is also closed to activate a start magnet 44 controlling motor 47 to initiate a first printing cycle recording the first selection. The printing mechanism closes a microswitch 41 to energize a relay 42 changing over contacts 33a, 35(1)- 35 (16) and 43. A relay 46 is activated via switches 40a, 43 to close contacts 46(1)-46(3). A signal passed through contact 46 (2) requests access to a central equipment. When the central equipment is ready to receive information a signal is transmitted via contact 46(1) and returned to the central equipment along the appropriate lines 38 to record the first selection. A second selection is now entered on the keyboard and transmitted to the control equipment via a second set of transmission lines 39. After acceptance of the first and second selections, the central equipment applies a signal on line 27 to energize relay 48 and close contacts 48(1), 48(2) and open contact 48(3) to deactivate relay 46. Contacts 40a, 48(2) complete a circuit to a start magnet 44 which energizes motor 47 to print the second selection. A parity check circuit (Figs. 5, 6, not shown) is used to detect faults in the code lines and has switches operated by relays 34(1-16) and the relays in lines 39. If a non-runner selection is made relay 52 is activatedto connect switch 40a to relay 50 via contacts 52(3). At the start of a race relay 53, opposed to relay 54, is activated. If a late selection is made the relay 53 is connected to relay 50 via a void key 55 which is depressed to issue the void ticket. Also if a key jams, a relay 60 will be operated to open contacts 60(1), 60(2) and connect it to the void key. A sensing switch may be used to detect when more paper is required for tickets.

Abstract: 1,238,978. Valves. AMERICAN STANDARD Inc. 11 Nov., 1969 [3 Feb., 1969], No. 55060/69. Heading F2V. A mixing valve cartridge 35, which is adapted to be incorporated in a faucet comprises a base 49, a two-piece cover 51, 53, a valve seat 151, a slidable valve member 175, and an operating mechanism 39, 93. Formed in the end face 139 of base 49 are three ports of which two, the inlet ports, are of identical size and have disposed therewithin sealing rings 140, and of which the third, the outlet port, is larger than the first two and has disposed therewithin a sealing ring 149, all sealing rings project beyond the end face 139 and into recesses formed circumadjacent corresponding ports in the seat 151. Selective communication between the inlet ports and the outlet port is achieved by an annular channel 177 formed in the esat-contacting face of valve member 175, such channel having in the vicinity of the inlet ports a stepped side wall which serves to gradually change the flow direction and hence to minimize noise. The operating mechanism is formed by a bush 93 which is allowed a limited degree of rotation between members 51 and 53 as a result of the provision of mutually engaging lugs (103, 117, Fig. 8, not shown), and of a member 39 which is allowed a limited degree of rocking within the bush by virtue of the provision of stops 135, 137. The valve member is also restricted in its motion by the provision of a tail section 185 which at all times is at least partially disposed between a pair of guides 191, 193. A lubricant containing plastics material layer 199 is provided on the cover-contacting surface of valve member 175. In use, rocking of member 39 from the vertical (fully closed) position places recess 177 in communication with the inlet ports in the seat and also increases its degree of communication with the outlet port. Variation of the ratios of liquids entering the outlet port from each of the two inlet ports is effected by turning bush 93 about its axis, maximum variation being obtained when the valve member has been moved to the position shown in Fig. 11. When mounted in a faucet, the cartridge sealing rings 140, 149 egnage a manifold (21, Fig. 3, not shown), and the assembly is completed by a decorative spout and escutcheon (23 and 37 respectively, Fig. 1, not shown), a single operating lever (41, Fig. 1 ) being mounted on member 39.

A brake pressure control valve 7 for a vehicle for regulating pressure between an hydraulic pressure supply line 6, a brake line 9 and a return line 8 has a first stage pilot valve 16 responsive to a signal from an antiskid detector, the pilot valve output pressure via lines 32, 33 controlling a driving piston 35 of a second stage valve 17, piston 35 actuating a pressure regulator piston 18 through a rod 38 sliding within a bore 37, piston 18 having lands 44, 45 which control hydraulic pressure to the brakes by opening or closing conduits 28, 31, 30 leading from cylinder 19 to conduits 6, 9, 8 respectively. Fluid from inlet 6 passes into cylinder 19 via conduit 28, pressure at the outside faces of lands 44, 45 being equalized by provision of bores 47, 48 formed therein, the pressure being further transmitted to a third cylinder 39, housing a return piston 40, via bore 49 and also a conduit 50. A skid signal actuates a coil 23 to move a flapper 22 of valve 16 supplied with fluid from inlet 6 through a filter 27, conduit 26, orifices 24, 25 and nozzles 20, 21 to increase pressure in conduit 32, thereby moving pistons 35, 18, 40 rightwardly land 44 sealing a groove 51 of inlet 6, thus decreasing pressure supplied to the brakes through conduit 9. If the vehicle wheels still skid, a further signal moves the flapper 22 to increase conduit 32 pressure to move the pistons further rightwardly, land 45 uncovering groove 52 to release the brake line pressure to the return line 8 via cylinder 19. In another embodiment there are only two cylinders housing a driving control piston and a driven pressure regulating piston, and in a further embodiment the regulator piston communicates directly with the pilot valve and drives a second piston similar to piston 40 of the first embodiment.
