Title: Means for fitting circlips to shafts
Inventor: DUNCAN ANGUS WELLESLEY
IPC: B25B27/20
Filed: 1961-10-31
Abstract: 943,358. Fitting circlips to shafts. MINING ENGINEERING CO. Ltd. Oct. 26, 1962 [Oct. 31, 1961], No. 38836/61. Heading B4C. Means for fitting a circlip to a shaft comprises a table 10 having an opening 12 through which a shaft can be passed, a peg 13 fixed in the table to receive one end of the circlip and a peg 14 adapted to receive the other end of the circlip and carried by a member 16 which is movable in a direction to open the circlip by a compressed air actuated piston-and-cylinder device 24, 25, 26. The peg 13 is mounted in a block 15 secured to the table and the peg 14 to the member 16 in the form of a bar connected to a plate 22 via a pin-and-slot device 19, 21. The plate is slidable on the table and connected to the piston-rod 24, an opening being provided in the plate so that, in the inoperative position shown, a shaft may be withdrawn through the opening 12. The bar 16 is urged by a spring 17 against a distance piece 18 abutting the block 15, thereby accurately setting the distance between the holes in the ends of the circlip. In operation, a circlip is first located in the pegs 13, 14, compressed air then being admitted to the cylinder 26 so that the plate is moved to the right. During the initial movement of the plate, lugs 23 formed thereon move over the surface of the circlip thereby maintaining it flat, continued movement causing one end of the slot 21 to engage the pin 19 and thus move the bar 16 to expand the circlip. A shaft is then inserted through the opening 12 to rest on a support 31, the latter being adjusted to bring a groove formed in the shaft into alignment with the circlip. The supply of compressed air is then cut-off and the piston returned by a spring 28 to thereby allow the circlip to contract into the groove. The table 10 may be arranged in a vertical instead of a parallel plane.

Title: Process for the preparation of high purity terephthalic acid
IPC: C07C51/487
Filed: 1964-09-24
Abstract: Terephthalic acid, which has been obtained by oxidizing a p-dialkylbenzene with a gas containing molecular oxygen in a liquid medium in the presence of a cobaltic compound, is purified by separating the acid from the reaction medium and then treating it at 180-230 DEG  C. with a gas containing molecular oxygen in an aliphatic monocarboxylic acid of 2-4 carbon atoms or an aqueous solution thereof containing not more than 50% by weight of water, the proportion of terephthalic acid being 6-100 parts per 100 parts of aliphatic acid or aqueous solution thereof and the conditions being such that at least 50% of the terephthalic acid retains its solid form in the refining medium.  The process is effected at sufficient pressure to maintain a liquid phase and may be effected in the presence of a catalyst, e.g. cobalt, manganese, nickel, chromium or lead or a compound thereof.  Examples and experimental results are given.

Filed: 1971-08-20
Abstract: 1350492 Positioning transducers INTERNATIONAL BUSINESS MACHINES CORP 20 Aug 1971 [19 Sept 1970] 39167/71 Heading G5R In a method of bringing a transducer to a desired setting, an alternating flux is set up in the transducer air gap and the signal induced in one or both of two crossed conductors arranged above the air gap is sensed. In the arrangement shown, crossed conductors 4, 5 are connected to differential amplifiers 6, 7, and the desired setting with conductor 4 parallel to the air gap 2 and with the join-point over the gap centre is found by adjusting the relative positions until the voltage ratio U 2 /U 1  is greatest. In a second method (Fig. 2, not shown), conductor 4 is directly activated with voltage U 2  and the signal in conductor 5 is sensed as the relative positions are varied.

Filed: 1956-12-24
Abstract: 806,365. Woodworking. EXACTA MASCHINEN A.G. Dec. 24, 1956, No. 39199/56. Class 145. Small boards of pre-determined length for the manufacture of parquetry staves are produced by individually gripping a plurality of boards 5, Figs. 8 and 9, at one time at their ends, cutting off in succession a single small board 8 from each of the gripped ends, and then regripping the remaining portions of the larger boards in preparation for further cuts. The boards are clamped around the periphery of a drum 28 which is rotated so as to carry each board in turn through two circular saws 4 which cut off a small board 8 ; each board is secured on the drum by a jaw 3 acting against two reference stops 2. After a small board has been cut off, the remainder of a board is lowered mechanically or under gravity on to a reference stop 22 on a table 29 in readiness for the cutting of another small board when next the large board reaches the saws 4. The small boards 8 are transferred by a conveyer 17a to a combined planing and ripping machine 16, Fig. 11, which includes two axially-aligned and rotatable clamping plates 18, 19 having around their peripheries a number of clamping jaws for the boards. When clamped on the plate 18, the boards are brought successively between planing cutters 7, and they are then transferred to the clamping plate 19 which feeds them past ripping saws 13. On the plate 19, each board is clamped against two reference stops 12 which has the same spacing as the reference stops 2. The cut staves so formed drop onto a conveyer 17b for sorting. The setting of the reference stop, saws and cutters is adjustable.

Abstract: 1346540 Rock drills ATLAS COPCO AB 29 Aug 1972 [7 Sept 1971] 39980/72 Heading B3C [Also in Division F1] A rock drill is rotated by a pressure-gas rotary-vane-motor 1, and is fed by a rotary-vane motor, or a double acting ram 4, an unloading valve 7 connected to the fluid inlet 35 of motor 4 being arranged to connect the inlet to a low pressure supply when the pressure in motor 1 decreases to a predetermined pressure. In operation, pressure gas is supplied from a conduit 12, through valves 11, 10, and when the resistance to rotation of the drill connected to motor 1 increases, the speed of the motor decreases, whereupon a valve 9 connects conduits 16, 14, to atmosphere, until the pressure in these conduits equals that in conduit 15. When the pressure in conduit 14 reaches a low predetermined level which can be adjusted by spring 8, valve 7 is moved so as to connect inlet 35 of the motor to atmosphere and the feed rate is reduced. Simultaneously, conduit 5 is closed so as to prevent unnecessary discharge of gas. In a modification, a regulator (18), Fig. 2 (not shown), and a venting valve (19) are included in the circuit.

Abstract: 1,038,862. Electromagnetic relays. ENGLISH ELECTRIC CO. Ltd. Nov. 7, 1962 [Nov. 8, 1961], No. 39981/61. Heading H2B. The armature 6 of a polarized relay is biased against an adjustable spring stop 12 by a spring 11 and carries a contact blade 13, 14 which co-operates with a fixed contact blade 15, 16 provided with an adjustable back stop 20. During attraction of the armature 6 it is subjected to a spring bias which increases in steps. Initially armature 6 moves against spring 11 alone, then against the combined bias of spring 11 and contact blade 15, 16, the bias of blade 15, 16 being increased when it abuts the adjustable stop 20. The relay may be adjusted so that it is held closed by the flux of a permanent magnet 1 or released by the spring bias when coil 5 is de-energized. If the relay is retained closed by the permanent magnet it may be released manually, mechanically or by reverse excitation of the coil. An adjustable residual screw 10 co-operates with the armature. The coil 4 may be replaced by two coils energized by currents of opposite polarity so that the relay responds to the net effect of two or more signals. The contact springs are adjustable.
