The pliable bearing material 44 is moulded to relieved surface areas 40, 42 on the bushes 34 and forms a circular surface.
Patent GB-273832-A (GB)
Abstract: 273,832. Ramage, A. S. April 13, 1926. Motor spirit.-Ozonides suitable for use as an addition to motor fuel are obtained by treating with ozone or ozonised air a liquid mixture boiling at 125-250‹ C. and containing, in addition to olefines, about 10 per cent of paraffins and a relatively small amount of terpenes and aromatic hydrocarbons. The mixture is run from a vessel 1 into a still 3, wherein it is heated to about 80‹ C. and treated with ozonized air admitted through a pipe 5. The vapours evolved from the still 3 are passed through a pipe 9 to a condenser 10, and the condensate is collected in a vessel 15. The initial material may be treated in batches or may be run into the still as the treatment proceeds.

Patent GB-1069162-A (GB)
Title: Improvements in or relating to the crimping of textile yarns
IPC: D02G1/02
Filed: 1964-07-02
Abstract: In a crimping process, two (or more) running yarns (or filaments or bundles thereof) are plied together along a length, heat-set and then pulled apart at the same speed in different directions.  The yarns are fed, before or after plying, through a guiding device, comprising fixed, pivotable or slidable rollers, pulleys or rods, which equalises the tensions of the respective yarns.  Thus, the device, under the action of a high yarn tension, moves transversely and to one side or the other of the extended axis of plying (and in the plane of the direction of yarn travel to and from the plied length) into a position such that (a) the high tension yarn is magnetically e.g. eddy current, and/or mechanically braked e.g. by sliding contact with porcelain cylindircal segments, and a low tension yarn is removed from a braking influence or (b) the high tension yarn is temporarily removed from engagement with a corresponding feed roller and the low tension yarn is restored thereto as by displacement of the yarns into and from a peripheral recess, or one of two such recesses, in one of a pair of feed rollers or (c) the yarn path between conical feed rollers, and therefor the yarn speeds, are correctively adjusted.

Patent GB-339009-A (GB)
Title: Improvements in delivery mechanism for use with printing machines
IPC: B65H31/08
Filed: 1929-09-11
Abstract: 339,009. Quick, C. G., and Whitehead, W. A. Sept. 11, 1929. Delivery apparatus. - In mechanism for delivering printing products in batches of predetermined number, the products are deposited in compartments formed by fingers 2 on an endless chain 3 which is moved slowly while each batch is being collected and then given a quick movement to present the next compartment to the delivered products by mechanism comprising a constant drive component and a variable superposed drive component. Each batch is deposited on endless tapes 28 which pass betweer the fingers 2 and are moved to carry the batch away during the time a fresh batch is being col lected but are at rest during the depositing of a batch thereon by the quick movement of the chain 3. The tapes 28 and chain 3 are actuated from a constantly rotating shaft 9. A worm 8 rotatable with but slidable on the shaft 9 gears with a wormwheel 7 on one of the carrying shafts 6 of the chain 3. A link 13 having a roller 12 engaging a grooved collar 11 fixed to the worm 8 is adjustably pivoted at 39 to a lever 14 having a roller 18 running in a grooved cam 19 on a shaft 21. The shaft 21 is driven from the shaft 9 through a worm-and-wormwheel coupling 23, 22. The worm 8 is thus reciprocated along the shaft 9 as well as rotated with it so that during the motion of the worm in one direction it decreases the speed of the shaft 6 and during its movement in the opposite direction it increases the speed of the shaft 6, so as to collect and deposit the batch of products. The shaft 26 of one of the guide rollers 25 of the tapes 28 is driven from the lever 14 and cam 19 by gearing 31, 30, 24, 27 similar to that driving the shaft 6. In this case, however, the drive of the shaft 26 due to the rotating of the worm 24 is completely neutralized by the drive due to the reciprocation of the worm 24 in one direction so that the tapes remain stationary to receive the completed batch. During the reverse movement of the worm, the reciprocating and rotary drives are additive, so that the batch is carried away. To adjust the movement of the chain 3 according to the thickness of the products, the bolt 39 connect the link 13 and the lever 14 can be moved along a slot in the lever 14.

Title: Improvements in and relating to shaft couplings
IPC: F16D3/10
Filed: 1924-11-19
Abstract: 246,613. British Thomson-Houston Co., Ltd., and Griffiths, L. Nov. 19, 1924. Centrifugal governors.- In shaft couplings for automatically adjusting the timing of intemal-combustion engine magnetos with change of speed, a ring 6, pivoted to a member 2 on the magneto shaft 3 by diametrically-opposed pins 7, is biassed by springs 8 to an inclined position and carries on a pin 9 a roller (not shown), which engages an inclined slot 11 in a sleeve 5 secured to a member on the engine timing-shaft (not shown), the sleeve 5 being also slotted to clear the pivots 7. When the speed rises above a predetermined value, the ring 6 turns' under centrifugal force about its pivots 7, and so effects relative angular adjustment of the shafts. A dustexcluding cover is provided. Specification 7758/15, [Class 7 (iv), Internal-combustion engines, Igniting in], is referred to.

Abstract: 303,231. Bethel, J. N., (Summers, K. E.). Oct. 18, 1027. Rotating-tool apparatus; round h@i@s, enlarging and trucing.- A lapping head for lapping the internal surfaces of cylinder walls, collars, bushings &c. comprises a lap-holder which is slidable with respect to its driving member to bring a lapexpanding device into operation. The support 10 is recessed to receive segmental holders 12 which have undercut recesses to accommodate lapping blocks 14, the latter being secured by clamping rings 15 and longitudinal bars 16. Each block holder is fitted with studs 20 projecting through openings in the member 10 and engaging conical surfaces of a slidable expanding-plunger 22. The expansion of the blocks is resisted by spring rings 25. The lap is driven by a member 30, connected to a driving shank 61 by a universal joint 60 and having a head 31 which is fitted with a stud 32 which passes through a slot in the member 10 and through a slot 39 in an adjustable sleeve 36. In order to expand the lap, the member 30 is pushed into the member 10, thus causing a spring 42 to move the plunger to the right. the parts being retained in this position by engaging the stud 32 with the transverse end portion 41 of the slot 39. The diameter of the lap is limited by means of a headed rod 52 which is adjusted by a nut operated by worm gearing 57. The lap-expanding pressure may be regulated by adjusting the sleeve 36 by means of nuts 37.

The camera itself may be used for this purpose when the analyzing pictures are projected by the taking lens on to a screen. Provision is made in the camera for setting the capping disc 15 with its slots in register with the transparent apertures in the scanning disc 13. The scanning disc 13 may be a photographically exposed glass plate and the capping disc 15 may be a thin apertured steel plate, while to prevent the capping disc from scraping the photographic plate P due to axial movements of the capping disc 15 during rotation the scanning disc carries a ring 60 having a turned-over flange 62 overlying the edge of the capping disc.
