Abstract: 723,746. Protective arrangements; selfcontained supply systems; modifying the reactive characteristics of circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 14, 1953 [June 10, 1952], No. 14594/52. Class 38 (4). In a fluorescent lighting installation, e.g. on a railway coach, wherein an electric motor 3 drives an alternator 2 to supply an alternating current circuit in which are connected the lamps 1 together with a capacitance 4 arranged in series between the alternator and the lamps so as to compensate wholly or partly the internal reactance of the alternator, and/or a power factor correction capacitances 5 parallel connected with the lamps, means responsive to the starting conditions of the motor armature circuit are provided to modify the alternating current circuit conditions, during running up of the motor-alternator set, in such manner that the alternating current circuit is not resonant in the starting speed range. As shown, the means comprise contactors 6, 7 whose contacts 6<SP>11</SP>, 7<SP>11</SP> respectively short- and open-circuit the capacitances 4, 5 when their coils 6<SP>1</SP>, 7<SP>1</SP> are energized by virtue of the high starting current which flows in a motor armature starting resistance 8. The contactors drop out to effectively reconnect their capacitances when normal running conditions obtain in the motor armature. In another embodiment (Fig. 7, not shown), a saturable reactor is arranged to virtually shortcircuit the alternator during starting. Instead of two contactors a single contactor having two sets of contacts may be used, and such contactor(s) or reactor alternatively may be responsive to conditions in a main field or an interpole field winding connected in series with the motor armature. Specification 614,519 is referred to.

Title: Improvements in or relating to compressor unloading apparatus
IPC: F04B39/02
Filed: 1956-05-12
Abstract: 798,802. Compressors. COLEMAN CO., Inc. May 12, 1956, No. 14859/56. Class 8(1). A compressor comprises compression chambers 3 and 4 in which work pistons 12 and 13 driven by a motor through a crank shaft 5 and connecting rods 9 and 10. Each chamber is provided with a valve unit 17 which comprises a cage 24, of hollow conical form having a tubular portion 25 extending downwardly from its base. The cage is riveted to a piston 44, in cylinder 46, supplied with oil from a gear pump 14 through conduit 16, past valve 52, and conduit 50, the gear pump being driven by the compressor motor through crank shaft 5 and chain 11. In operation when the pump is idle there is no oil pressure from the gear pump 14 and the cage 24 is raised off seat 26 by a spring 57. As the crank shaft 5 begins to rotate, gas enters through the inlet 20, on the suction stroke passes round the side of cage 24 and enters the chamber 4 around the serrated edges of a disc-shaped valve member 30 and on the compression stroke the gas passes back through the same passages and out of the inlet 20, until the gear pump 14 supplies oil at a sufficient pressure to seat the cage 24 on the seating 26 when, on the suction stroke gas enters through inlet 20 passes through ports 27 of the cage member to the chamber 4. On the delivery stroke the valve member 30 is forced against the lower face of the cage member to close the control passage and gas is delivered past a non-return valve 37 to the exhaust chamber 31 having outlet 35. The oil line 50 has a bleed line 54, of small diameter, to return oil to the sump. The control valve 52 may be used to prevent oil being delivered to the cylinders or starts the motor, until a predetermined condition exists for example when the driving means reaches a desired temperature and this valve may be operated manually or automatically. In a modified form the inlet valve cage 24 has its lower tubular portion 25 extending downwards to the -level of the chamber 4, in its closed position, a flexible leaf member is secured to the top of the chamber 4 across the cage opening and its width is less than the diameter of the opening but greater than the diameter of the central opening of the tubular portion so that the leaf acts as a non- return valve when the cage is seated but gas can enter and leave through the inlet 20 when the cage is lifted away from its seat 26. In this embodiment there is only one passageway for the gas namely through the holes 27 and the central opening of the tubular member.

Filed: 1950-06-16
Abstract: 680,375. Bookbinding. PLASTIC BINDING CORPORATION. June 16, 1950. No. 15157/50. Class 16. A bookbinding machine for uncurling resilient curled fingers of a binder, comprises a carriage plate movable towards and away from locating means for the binder and supporting a pair of slidably mounted superposed strips each having a plurality of hook members extending towards the locating means so as to be engageable between the curled fingers, and means coupled to at least one of said strips to move the hook members from a superposed to a spread position to engage behind the fingers as the carriage plate is advanced towards the locating means, so that the fingers are uncurled as the carriage returns. The base 20 carries a series of upright pins 84 which pass between the binder fingers, the backbone of the binder resting against the pins. A carriage plate 74 is slidable on the base, being reciprocated by blocks 70 guided in slots 72 in the base. The blocks are reciprocated by cranks 64 on a shaft 28 mounted between uprights supporting the base, and rotated between two positions by a handle 30. Clamped on to the rear part of the carriage plate are two steel strips, the upper strip being formed with hook portions 110 and the lower strip 104 with oppositely disposed hook portions. The carriage plate has projecting teeth aligned with the pins. The rearward position of the carriage plate is defined by adjustable stop members 86, 88, parts 94, 96 of which arrest the carriage plate motion. In this position, the hook portions and the teeth on the carriage plate are all aligned with the pins, projecting backwards between the fingers of the binder. On retraction of the carriage plates, almost at once nose portions 144, 146 of cam plates 124, 126 move clear of the members 86, 88, and springs 148 pivot the cam plates to shift the strips to right and left, whereupon the hook portions are spread and engage behind the fingers. Further retraction uncurls the fingers, when the sheets can be inserted. The forward position of the carriage plate is defined by a key 38 on a member 36 on the shaft 28, the key engaging a pin 60, a ball detent preventing rearward movement of the carriage plate under the tension of the uncurled fingers. According to the diameter of the fingers, the limits of the carriage plate stroke are adjustable by shifting the members 86, 88 and adjusting the member 36. During the last part of the rearward movement of the carriage plate, the hook members move into alignment with the pins and clear of the fingers. Specification 404,806 is referred to.

Title: Improvements in or relating to the colouration of textile materials containing cellulose esters
IPC: D06P5/12
Filed: 1935-05-24
Abstract: Cellulose esters, dyeing; printing.--Pattern effects are produced upon a textile fabric containing a cellulose ester by applying thereto in a pattern a colouring matter or a component convertible into a colouring matter, having little or no affinity for the cellulose ester but good affinity for cellulose, before or after saponifying the cellulose ester in a pattern coinciding in part only with the pattern in which the colouring matter is applied or the component is applied and developed.  The locally saponified fabric may be obtained by the local application of a saponifying agent thereto or by the use of intermittently saponified filaments or yarns therein.  As colouring matters or components may be used, for example, direct cotton dyestuffs, chrome mordant printing colours, e.g. Chromazurine DN or G, the sodium salts of enolic coupling components for azo dyes, such as b -naphthol, pyrazolones, arylides of 2 - 3-oxynaphthoic acid and diacylacetyl derivatives of aromatic diamines, and sulphuric or other esters of leuco vat dyes, e.g. those of the Indigosol series.  Dyestuffs having affinity for cellulose esters but not for cellulose may be incorporated in the colouring matter compositions.  Oxidizing agents, e.g. sodium nitrite or aluminium chlorate may be present in compositions containing the esters of leuco vat dyestuffs together with ammonia or alkali to prevent premature oxidation, in which case oxidation catalysts, e.g. a copper salt or a vanadate, may be preliminarily applied to the fabric.  Further effects may be obtained by preliminarily printing with a mechanical or other, e.g. a hydrosulphite, resist. The following examples are specified.  (1) A cellulose acetate woven fabric is printed in a bold design with an aqueous saponifying composition containing caustic soda, British gum and glycerol, dried, washed with dilute acid, washed free from acid, again dried, overprinted in a small design with an aqueous composition containing Indigosol yellow HCG, Indigosol printing blue IGG, thiodiglycol, ammonia, gum tragacanth and sodium nitrite, again dried, developed in dilute sulphuric acid at 60 DEG  C., washed, soaped, washed and dried; the saponified areas of the Indigosol print are deeply and the unsaponified areas faintly coloured; (2) A fabric having a weft of cellulose acetate and a warp of intermittently saponified cellulose acetate is impregnated with an aqueous solution containing ammonium vanadate and tartaric acid, dried, printed with an aqueous composition containing Indigosol golden yellow IGK, gum tragacanth, tartaric acid and aluminium chlorate, dried, hung in the air for about a day, washed and dried; the saponified and unsaponified areas of the print are coloured strongly and faintly respectively.
