Patent GB-934685-A (GB)
Title: Improvements in or relating to 2-alkylmercapto-thiaxanthenes
IPC: C07D409/04
Filed: 1961-01-13
Abstract: The invention comprises compounds of the general formula: <FORM:0934685/IV(a)/1> and their acid addition salts wherein R1, R2 and R3 represents an alkyl group containing at most 4 carbon atoms, R4 represents a hydrogen atom and R3 and R4 together represent the ethylene group with the proviso that R1, R2 and R3 need not be dissimilar, the preparation thereof by reacting a thiaxanthone of the formula <FORM:0934685/IV(a)/2> with an organo-metal compound of the general formula <FORM:0934685/IV(a)/3> and pharmaceutical compositions containing them.  2-Alkylmercapto-thioxanthones, in particular 2-methylmercapto-thioxanthone, are prepared by reacting an S-alkyl-p-bromothiophenol, especially p-bromothioanisole, with thiosalicylic acid and the product cyclised with thionyl chloride/aluminium chloride or with thiosalicyclic acid ester and the product cyclised with phosphorus oxychloride.  Pharmaceutical compositions comprise compounds of the invention together with an inert carrier.  The compounds show a narcosis-potentiating effect, furthermore 2-methylmercapto-9-(g -dimethyl-amino-propylidene)-thiaxanthene has an adrenolytic sedative, antipyretic and hypothermal effect, whereas 2-methylmercapto-9-(N-methylpiperidylidene-41)-thiaxanthene shows a strong anti-histaminic effect.

Title: Improvements relating to chlorination processes
Inventor: GROVES JAMES DENNIS
IPC: C22B1/08
Filed: 1957-01-16
Abstract: In the chlorination of a ferro titaniferous material in a static or fluidized bed by passing chlorine upwardly into a hot bed containing the material and a reducing agent, the hot reaction products are quenched by the injection of a vaporisable or gaseous coolant into the hot reaction products, in an amount such that the reaction product gas temperature is reduced from between 900 and 1000 to below 700 DEG C. and preferably from 300 to 400 DEG C. Chlorides of impurities such as zirconium, aluminium, magnesium, manganese, nobium and silicon and in particular ferrous chloride condense to the solid phase and are carried out in suspension with the gaseous reaction products.  Chilling is preferably effected by spraying the gases with a liquid coolant such <PICT:0872865/III/1> as titanium silicon, or tin tetrachloride or other liquid halides which may contain a sublimable solid, such as ferric chloride, in suspension. Alternatively or additionally cool gases such as carbon dioxide and carbon monoxide, which may be recycled from a later stage in the process, may be employed as coolant.  As shown in the Figure, a shaft furnace contains a bed of titaniferous ore and carbon maintained at 800-1000 DEG C.  Temperature control in the bed may be effected by withdrawing a portion of the bed cooling and recycling, cooling by the injection of an inert gas or a vaporizable liquid, or heating by the injection of an oxygen-containing gas which burns part of the carbon content of the bed.  Chlorine is injected through a pipe 4 and distributed by block 3 and the hot gaseous reaction products are exposed to liquid sprays 11, preferably of titanium tetrachloride which vaporize before they reach the walls 12 or the top of the fluidized bed.  Reaction products containing contaminant chlorides in finely divided solid form leave through line 13 at 300-400 DEG C. and are subjected to conventional cooling and collecting operations. Specifications 724,193, 762,583, 792,151, 794,666 and 813,489 are referred to.

Title: Piezoelectric phonograph pickup

Abstract: 863,889. Stereophonic pick-ups. CLEVITE CORPORATION. Jan. 19, 1959 [Jan. 20, 1958], No. 1841/59. Class 40 (4). A phonograph pick-up comprises two piezoelectric transducers linked with a single coupling member and a single stylus. As seen in Fig. 3, the transducers 27 and 28 are mounted in a block of rubber 26 at one end and are attached to a flat spring wire coupling member 29 which may be sheathed in plastic material. A notched portion 23 in the coupling member engages a compliant stylus arm 31 mounted as shown in Fig. 4 outside a casing 25, portion 23 of the coupling member 29 projecting out of the casing through slot 21. The transducers 27 and 28 are preferably set at right angles to each other and at 45 degrees to the vertical, but may alternatively lie in a common horizontal plane. The transducers are preferably of polarized ceramic material or a piezo-electric crystalline material such as Rochelle salt. The transducers may be connected in parallel to reproduce laterally cut recordings. As shown in Fig. 7, the transducers, here numbered 40 and 41, are of opposite polarization and may be mounted in rubber between electrodes 47, 50 and 51, which provide a parallel connection. If the transducers lie in the same horizontal plane and the top electrode of one is connected to the bottom electrode of the other (see Fig. 8, not shown), effects due to record warpage and turntable rumble cancel out.

Abstract: 210,762. Mulford Co., H. K., (Assignees of Reichel, J., and Huntoon, F. M.). Feb. 1, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Immunizing and like serums.-Bacterial antibodies are separated from antibacterial serum by adding living or dead bacteria to form with the antibodies a combination which is separated from the serum and then treated to recover the antibodies. A polyvalent antibody for pneumococci is prepared by injecting horses with pneumococci of three different types, obtaining the serum after antibodies have developed, and adding thereto an emulsion of living bacteria of the same types. The mixture is kept at a temperature of 37‹ C. for one hour, or at 20‹ C. for twelve hours, and then centrifuged. The sediment obtained is washed with salt solution, emulsified with salt solution containing 0.25 per cent sodium bicarbonate, and heated to 55‹ C. for thirty minutes to one hour to split off the antibody from the bacteria. The mixture is centrifuged and the liquid obtained is cooled, again centrifuged, and filtered through a filter candle. The solution of antibody is stated to be prophylactic and curative. A suspension of the antibody in distilled water is also referred to.

Abstract: 859,210. Snap-action switches. CLANG Ltd., AUSTEN, H. E., and HARWOOD, C. D. Dec. 31, 1958 [Jan. 21, 1958], No. 1994/58. Class 38 (5). A pull-operated ceiling switch has two actuators 30 co-operating with snap-action contact members (Fig. 6) similar to those described in Specification 803,314. As shown in Fig. 6, the rockable contact has a turned-up portion 13A to act as a stop, but this may be omitted if an additional contact is provided for two-way switching. The actuators 30 are secured to a spindle 28 by the flattened part 29 which also carries a cam-plate 33 having a cam portion 35. Two stirrup members 23, interconnected by a pillar 38, are attached to a pull-chain 19 by means of a link 18 and pin 22. When chain 19 is pulled the piston 17 is moved downwardly against spring 21 and the pillar 38 engages one face of cam 35, tilting the stirrup members 23 until the pillar 38 seats in the part 36 of the cam-plate 33 (Fig. 7, not shown). Further movement of chain 19 causes the plate 33 to rotate spindle 29 and thus the actuators 30 and operates the switch. On release the stirrup members 23 revert to the position shown but the plate 33 remains tipped to the opposite side. Link 18 engages one of the notches 34 to lock the plate 33 in position until chain 19 is again pulled and pillar 38 rocks plate 33 and actuators 30 once again to the position shown.

The structure may be secured to the ceiling joists 15 or suspended therefrom by strips 16. The lighting elements 33 and reflectors 30 are carried by members 28 supported by bars 18 which close the undersides of the bracing members 11. The light diffusing means C consists of a front panel 37 and a rear panel having dished parts 36 which register with the openings of the reflectors 30 and is held in place by a rod 23 having at the lower end a finger piece 52 and at the upper end a cross piece 54 which passes through a slot in the member 18 and when turned through a right angle holds the diffusing means in contact with the reflectors 30. A chain 26 sliding on rod 23 is anchored to the member 18 to limit the downward movement of the diffusing means C. In a modified form, the mounting structure comprises a grid of intersecting inverted T- bars suspended from the rafters and carrying an inverted pan 69, Fig. 11, supporting reflectors 68 and lamps 84, the reflectors being closed on the underside by light diffusing covers 72. A flanged front panel 91 is united to the covers 72 by curved panels 73 and is supported from the mounting member by fasteners H.
