Abstract: 938,976. Automatic brake adjusters. BENDIX CORPORATION. May 23, 1961 [May 24, 1960; Sept. 22, 1960], No. 18603/61. Class 103 (1). [Also in Group XXIV] A brake-actuating, fluid pressure motor includes a piston 14 movable in a cylinder 12, and an automatic adjuster 20 comprising abutment means 36 against which the piston is normally biased by a return spring 48 and which is resiliently yieldable to permit the piston to move backwards beyond the normal position in which it is biased by the return spring. As shown, the adjuster 20 includes a stem 22, the boss 23 of which is held against the cylinder end wall by a washer 24, and a piston-positioning sleeve 28 having a flange 30 resiliently forced by a spring 34 against the boss 32 of the stem. The sleeve 28 is coupled to the piston by a split friction ring 36 which grips the sleeve and is maintained against the wall 39 of the piston by a tubular member 40 coaxial with and movable with respect to the sleeve. A thrust washer 46 is secured to the piston and the distance j between the confronting end surfaces of the washer and the member 40 provides a lost motion for the piston. A pin 50 projects into the slot of the split ring 36. Fluid pressure delivered to the chamber 18 moves the piston 14 together with the washer 46 and the spring 48 is compressed so that the washer then engages the member 40 and on continued movement of the piston the member moves against the frictional resistance of the ring 36, the latter being pushed along the sleeve 28 to a position corresponding to the engagement of the friction pad 16 with the brake disc. Release of the pressure in the chamber 18 allows the spring 48 to return the piston until the ring 36 re-engagss the wall 39. Specification 861,648 is referred to.

Title: Improvements in and relating to the chlorination of organic compounds
IPC: C07C17/12
Filed: 1925-07-22
Abstract: 259,329. Silberrad, O., and Boake, Roberts & Co., Ltd., A. July 22, 1925. Chloro compounds.-The chlorination of organic compounds is carried out by means of sulphuryl chloride in the presence of one or more of the following catalysts :-The chlorides of phosphorus, manganese, arsenic, selenium, tellurium. antimony, bismuth, molybdenum, bromine and, except in the manufacture of monochlorobenzene, the chlorides of iron, sulphur and aluminium (anhydrous), the last mentioned being used only with such aromatic compounds as can undergo the Friedel-Crafts' reaction and only under conditions conducive to chlorination, i.e., in the warm and preferably at or near the boiling point of the sulphuryl chloride under atmospheric pressure. The joint use of sulphur and aluminium chlorides in the manner described in Specification 193,200 is excluded. The catalysts may be added as the anhydrous chlorides, or the metals that form chlorides under the conditions of the reaction may be added as elements. The chlorides of antimony, bismuth, iron, molybdenum, aluminium, tellurium and selenium are especially valuable in effecting substitution in the ring. Phosphorus. and to a less extent manganese, arsenic, and bromine favour side chain substitution. Sulphur accelerates both types of substitution. The chlorination is preferably carried out under the influence of sunshine or some other actinic light and preferably at or near the boiling point of the mixture. Compounds such as acetic acid, benzoic acid, methylanthraquinone, dichlororesorcinol, chloroindanthrone and dichloroindigo, which are difficultly chlorinated by sulphuryl chloride alone may be chlorinated by the addition of these catalysts. Examples are given of the preparation of xylyl chloride using phosphorus pentachloride ; chlorotoluene or pentachlorotoluene using antimony trichloride; monochloracetic acid using tellurium. In the last example acetic anhydride is also produced, and can be separated by distillation.

Title: Screen printing machines
IPC: B41F15/08
Filed: 1968-04-24
Abstract: 1,209,993. Screen printing machines. SIEBDRUCKGERATE VON HOLZSCHUHER K.G. 24 April, 1968 [28 April, 1967], No. 19390/68. Heading B6C. A screen printing machine comprises a baseplate for carrying material to be printed, the base-plate being reciprocal in its longitudinal direction between first and second limit positions, and a screen carrier mounted on the base-plate so as to be longitudinally immovable relative thereto. As shown in Fig. 1 a device 1 for clamping a screen 7 in position for printing is connected to a base-plate 2 which is mounted for longitudinal movement in a table. The base-plate is reciprocated having a stroke of length H. In starting position I, Fig. 1, the plate 2 the material 8 to be printed is disposed thereon. The material 8 is brought to position II when the plate is advanced and the material in so doing passes under a longitudinally immovable but vertically reciprocable bridge unit 3 carried on the table of the machine so to span the base-plate 2. The unit 3 is then lowered a transverse member 9<SP>1</SP> acting as a stop barrier for the material 8 to prevent it being entrained when the plate 2 returns to its starting position. As the material 8 is held on the plate it moves with it towards the screen 7 thus taking up position III. A similar movement causes the material 8 to be advanced from position III to position IV and so on to position VII. Between each of the positions I-VII there is a forward or return stroke in the direction of the arrows indicated in Fig. 1. The unit 3 is twice the length of the stroke H and has two further members 9 in addition to member 9<SP>1</SP>. In position V the material 8 has been advanced so that it lies below the screen 7 which is fixed to the device 1. When the plate 2 moves forward from V, that is from right to left of Fig. 1, printing ink is applied to the screen and then the material by a longitudinally immovable squeegee assembly 4 which is controlled by a cam which lowers it for printing at the desired time. Slip between the plate 2 and the material 8 is prevented by vacuum applied through a chamber 10 below the screen. Magnetic means may be used instead of suction means. After the printing process the material 8 is moved to position VII and then removed from the plate 2. To accommodate materials of different thicknesses the device 1, unit 3 and squeegee 4 are mounted so as to be vertically adjustable. Material triangular in cross-section may be printed by the machine of this invention.
