Title: Improvements in or relating to combination selecting mechanisms of printing telegraph apparatus
IPC: H04L17/18
Filed: 1937-02-26
Abstract: 490,951. Type printing telegraphs. GRIFFITH, R. G. Feb. 26, 1937, No. 5900. [Class 40 (iii)] The case shift and other auxiliary mechanism of a printing telegraph receiver is operated by selecting means, separate from that used for type selection, in the form of a pack of combination plates. Pins 13 are fitted in extensions 19 of the selector members used for type selection and each may move laterally a corresponding one of a pack of plates, slidable in a casing 14. The plates, Fig. 2 (not shown), are provided with a number of holes certain of which, when a suitable signal is received, are moved into register with each other so allowing a projection 24b on an arm 24, pivoted at 25, to pass through them when, by means of an arm 28, it is lowered by a cam 1b rotating with a shaft 1. The plates are separated by thin washers threaded on pins and engaging the plates only at one side of the pins. The printing operation is effected by a lever 6 being struck by a pivoted arm 5 carried on a bell crank 2 operated by a cam 1a on the shaft 1. The printing mechanism is rendered inoperative when an auxiliary function is to be performed by a lug 31b depressing the arm 5 against the action of its spring 34 when the lever 31 follows the arm 24 downwards. The clockwise movement of the bell-crank 2, when moved by its cam la, is, however, communicated to the auxiliary mechanism by forcing the lug 31b to the right and so operating a link 26 to move about its pivot 25. Specification 441,090 is referred to.

Title: Improvements in processes and apparatus for forming squirrel-cage windings for induction motors
IPC: H02K15/00
Filed: 1925-03-04
Abstract: 243,950. Spencer, M. C. March 4, 1925. Casting-machines; moulds; patterns.-A process for 'casting the end-rings on squirrel-cage bars of induction motors consists in supporting the bars in vertical cylindrical relationship, supporting an open mould for an end-ring below the bars, pouring molten metal into the mould, and then by relative movement of the bar support and mould support, plunging the ends of the bars into the metal and holding the parts in position until the metal solidifies. Apparatus for this process comprises an open mould x supported on a table 14 carried on a column 15 which slides on a pedestal 16, the rotor core 19 carrying the squirrel-cage 20 and being mounted on a shaft 21 supported in a bush 17 secured to the pedestal. Relative movement of the supports is obtainable by a lever and cam 24, 22. The mould, Fig. 1, is formed by a flask 13 and block 12 between which sand is rammed on a follow board 10 carrying the pattern 11.

Abstract: 539,812. Indicating scales. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and NORWOOD, H. C. April 3, 1940, No. 6058. [Class 37] An indicating scale suitable for a wireless receiver comprises a set of co-axial members 1.. 6 corresponding to the wave ranges, each member being of rectangular cross section and made of a light transmitting material such as a synthetic resin. At one end of each scale member is a lamp, only one of which is shown, which is arranged to be selectively illuminated in accordance with the position of the wave range switch B. The light travels endwise round the selected scale member to illuminate it. To facilitate this the curved reflective surfaces of the scale members are highly polished and may be metallized. Also at the far ends of the scale members mirrors or further lamps may be provided. Scale markings may comprise light-interrupting incisions of rectangular cross-section in the members 1-6 or merely dark markings on the surface. A transparent cursor with a hair line D is geared to move with the tuning knob A. Rectilinear scale members may be employed.

Title: Improvements in or relating to the production of crepe yarns and fabrics made therefrom
Inventor: POTTER THOMAS HENRY
IPC: D02G1/00
Filed: 1953-03-05
Abstract: 730,498. Crepe yarns and woven fabrics. BRITISH NYLON SPINNERS, Ltd. Feb. 26, 1954 [March 5, 1953], No. 6119/53. Classes 120(3) and 142(4). A yarn of a synthetic linear fibre-forming polymer e.g. nylon, capable of creping on subsequent scouring or like finishing treatment, is produced by subjecting a continuous filament yarn to the successive treatments of inserting a low degree of twist i.e. less than half that finally attained ; setting the twist by an operation that also effects shrinkage of the yarn e.g. with steam at atmospheric pressure and temperatures of 190‹ F. dry bulb and 180‹ F. wet bulb after preheating for 20 minutes at 165‹ F.; sizing with a size containing a thermoplastic resinous material e.g. an aqueous solution of polyvinyl alcohol and boric acid ; inserting in the same direction as the original twist, a high twist i.e. 40-90 turns per inch ; heating sufficient to cause the size to hold the high twist but insufficient to set the twist on its own account, e.g. by steaming for 30 minutes at atmospheric pressure and temperatures of 190‹ F. dry bulb and 180‹ F. wet bulb. The yarn may be relaxed for periods of 12 and 24 hours under conditions of 50 per cent relative humidity between the first setting and sizing and after the final heating, and between sizing and high twisting, followed, in the latter case, by a period of 12 hours at 65 per cent relative humidity. When the yarns are incorporated in a fabric the size may be removed therefrom, as by an aqueous scouring treatment, to produce creped effects : in an example, a nylon crepe yarn is used in the weft of a woven fabric, the warp of which is of normal low-twist nylon yarn, two right-hand twist crepe yarns alternating with two left-hand crepe yarns ; the fabric is scoured to release the high twist and then set e.g. on a stenter.

Each pump piston assembly 33, 35 has an indicator rod 38. An initializing circuit 66 connects both actuating pistons 33 to drain ready for starting the system. Pump 50 has a pressure relief valve 65, and an accumulator circuit 215 for preventing pressure variations. Two pairs of pumps 31, 32 may be either operated alternatively at controlled rates, Fig. 6 (not shown), to provide required proportions of two liquids, or an electrically-controlled proportioning valve may be provided downstream of the two pairs of pumps, Fig. 6A (not shown).
