Title: The manufacture of phenylthioglycollic acids, containing halogen and alkylgroups in the nucleus
Filed: 1927-11-22
Abstract: 281,290. I. G. Farbenindustrie Akt.- Ges. Nov. 24, 1926, [Convention date]. Halogenalkylbenzene -sulphochlorides, mercaptans, and -thioglycollic acids.-Halogenalkylbenzenes are converted into sulphochlorides by treatment with chlorsulphonic acid at temperatures below 100‹ C.; a single sulphochloride is usually obtained the sulphochloride group entering in the p.position to a halogen atom. By reduction there are obtained the corresponding mercaptans which yield the corresponding thioglycollic acids on condensation with chloracetic acid. As parent materials trisubstituted benzenes contain two halogen atoms and one alkyl group, or one halogen atom and two alkyl groups are particularly suitable. According to examples, the following compounds are obtained :- (1) 1-methyl-5-chlorbenzene-2-sulphochloride, -2- mercaptan, and -2-thioglycollic acid from mchlortoluene ; (2) 1-methyl-2 : 4-dichlorbenzene- 5-sulphochloride, -5-mercaptan, and -5-thioglycollic acid from 1-methyl-2 : 4-dichlorbenzene : (3) 1-methyl-2 : 6-dichlorbenzene-3-sulphochloride, - 3-mercaptan, and -3-thioglycollic acid from 1-methyl-2 : 6-dichlorbenzene : (4) 1 : 4-dimethyl- 2 - chlorbenzene - 5-sulphochloride, -5-mercaptan, and -5-thioglycollic acid from 1: 4-dimethyl-2- chlorbenzene. Reduction of the sulphochlorides is effected by means of zinc dust and sulphuricacid and condensation of the mercaptans with sodium chloracetate in aqueous caustic soda solution, thioglycollic acids being isolated as free acids or as their sodium or calcium salts.

Title: Improvements in or relating to bowling pin spotting machines
IPC: A63D5/08
Filed: 1958-10-07
Abstract: 866,643. Skittle alleys. AMERICAN MACHINE & FOUNDRY CO. Oct. 7, 1958 [Dec. 6. 1957], No. 31975/58. Class 132(2). In bowling pin elevating mechanism in which pins are conveyed from the pit by an endless belt conveyer 24 into an annular trough 36 rotated by belt 40 and motor 46 about a horizontal axis, the pins being lifted thereby to a discharge station S2, the pins are retained in the trough at the upper part of its travel by a guide rail 82 fixed to the alley by brackets 84 and having at station S2 a discharge gate opened automatically if the spotting mechanism requires a supply of pins. As shown, pin-receiving pockets are defined in the trough by studs 70, 72 and the pins are guided into the trough by curved sloping side walls 28, 30. As the trough rotates in the direction of arrow A, the pins are engaged by a pivoted roller 78 which either seats them properly or ejects them so that they fall down wall 30 on to conveyer 24 again. The pins then pass into engagement with rail 82 and go round with the trough if the spotting mechanism is full. If, however, the spotting mechanism. needs pins, a solenoid 110 is energized and this withdraws a latch 119 from behind upwardly extending arm 112 of gate 88 pivoted to the rail 82 and forming a bridge between two spaced operative runs thereof. The weight of a pin then forces the gate open and the pin falls into member 95 whence it is withdrawn by conveyer 98. The gate then closes under the influence of gravity and a light spring and is held by the latch if no further pin is required. The roller 78 may be replaced by a sphere hanging freely on a shackle or by a coil spring finger. The first part of the rail 82 may be replaced by a number of spaced spring fingers mounted on an arc in front of the trough. A modified form of gate is described. The centre of the annular trough may be closed as shown or cut out to allow hand access to the pit from the rear. In the latter case, the central bearing 56, 58 of the trough may be omitted and the trough may run on rollers fixed to the alley around the periphery of the trough. U.S.A. Specifications 2,767,983 and 2,767,984 are referred to.
