Title: Improved apparatus for spinning artificial slub yarn
IPC: H02P29/00
Filed: 1956-04-04
Abstract: <PICT:0816685/IV (a)/1> <PICT:0816685/IV (a)/2> In an apparatus for spinning artificial slub yarn comprising one or a number of spinning pumps, each of which feeds a spinneret, a low-and a high-speed drive being provided for driving the or each pump, each pump is connected by means of a freewheel or one-way clutch or by two of the three shafts of a differential gear to the low-speed drive and, via an abruptly-engaging and disengaging clutch, to the high-speed drive, the abruptly engaging and disengaging clutch being connected to the pump or to the third shaft of the differential gear and being actuated either directly or by a servo-mechanism by electronic control means (see Group XL (c)), the switching sequence of which is initiated by mechanical means, the arrangement of the freewheel or one-way clutch being such that, when the abruptly engaging and disengaging clutch is disengaged, the pump is driven by the low-speed drive, and when the abruptly engaging and disengaging clutch is engaged the pump is driven by the high-speed drive and the free-wheel or one-way clutch allows the pump to overrun the low-speed drive.  If a free-wheel or one-way clutch is used, the pump always produces the base denier when the low-speed drive is connected to the pump, and the high-speed drive, when connected to the pump, produces the base denier plus the extra required for the slub.  If a differential gear is used the pump is continuously driven by the low-speed drive, so that the pump always produces the base denier, whereas the high-speed drive needs only to provide for the smaller amount of material for the slub.  As shown in Figs. 2 and 3, the mechanical device for initiating the switching sequence of the control circuit comprises a wheel 11 which has peripheral teeth 12 and is attached to a shaft 15 journalled in a bearing 16 supported on a frame 13.  The shaft 15 is driven through the speed reduction gear 18 by means of an electric motor 17, and the rotation of the wheel 11 causes the teeth 12 to engage the roller member 14 of the micro-switch S1, forming part of the electronic control means, and thus to open and close the contacts of the switch.  The abruptly engaging and disengaging clutch may be an electromagnetic clutch repetitively energized and de-energized by means of the electronic control means.

Patent GB-105625-A (GB)
IPC: D03D41/00
Abstract: 105,625. Wielgolaski, F. H. A. April 20, 1916. Starting-arrangements. - In a loom for weaving fabrics with wooden laths &c. as weft material inserted while the loom is at rest, the inserted lath either acts upon a member which is moved to start the loom directly or indirectly through mechanical, electrical, or fluid transmission means, or is located in the path of a constantly moving member to transmit the movement to the starting-mechanism; the member moved by the lath may be so constructed and actuated that the laths are arranged in the fabric in zigzug fashion, as shown in Fig. 10. The lath 1, Fig. 1, introduced by hand in the direction of the arrow 2 may act upon a stop 4 resting on a support 5 to move a connected lever 7, pivoted at 8 to the frame 9, against the action of a spring 12, the motion of the lever 7 being transmitted directly by a link, wire, &c., or indirectly by closing an electric circuit or by gas or liquid transmission to the starting-mechanism. In other arrangements, the end of the lath enters between a roller and a guide, two rollers, or two jaws, the moved roller or jaw being secured to or forming part of a bell-crank lever. In automatic insertion, the lath 1, Fig. 6, is pushed from a magazine 16<1> by mechanism 17, 18 on to stop faces 13, which are depressed by a crank 19 and plunger 20 when the lath is fed, to move a lever 7 to start the loom. The lath may, alternatively, be placed by hand on the faces 13. Mechanical transmission of the movement of the lever 7 to the starting-mechanism may be effected by causing the lever 7 by a connexion to free a catch 22, Fig. 7, from a slide 23, which is thereupon moved by a spring 25 to cause a slide 26 to engage a groove in a disk 27 constantly rotated by a puliey 29, so that the slide 26 is moved upwards to start the loom. The slide 23 is restored to its engaged position by a cam-disk 33 and rod 34, and the spring 25 may be stretched constantly or just before the loom stops by a cam 31 and lever 30. In other arrangements, the catch 22 co-operates with a spring or weight actuated lever connected to the starting-mechanism, the spring, when used, being stretched at the proper time by a cam and lever. For producing the zigzag arrangement of the laths, a stop lever 53, Fig. 11, with two faces 51, 52 is pivoted to the lever 7 and is controlled by a cam acting on the end 54 to place the faces 51, 52 alternately in position to be struck by the lath 1. The lever 53 may, alternatively, be provided with projecttion or roller resting on a roller formed with grooves and recessed ribs which control the position of the lever, the grooved roller being rotated step by step by ratchet mechanism. In another arrangement, the stop faces are formed by the teeth 52, Fig. 14, and spaces 51 of a toothed wheel rotatablv mounted on the lever 7 and rotated intermittently by a skew ratchet-drum 68 and a fixed pawl 12, the lever 7 being mounted on the lay 14.

Title: Gas Turbine Power Units
Inventor: COLLEY ROWAN HERBERT
IPC: F02C7/277
Filed: 1967-03-07
Abstract: 1,150,815. Gas turbine plant. ROLLSROYCE Ltd. Feb. 8, 1968 [March 7, 1967], No.10563/67. Heading F1G. In order to reduce fire hazard in the enclosed space surrounding a gas turbine engine, the engine compressor 19 is rotated by a motor 22 after the fuel supply 27 has been cut off so as to blow cold air through the engine and thus effect rapid cooling of parts heated during engine operation, means 32 obturating the exhaust outlet 29 upon cessation of the rotation to prevent any fuel vapour which may have collected in the enclosed space from entering the exhaust duct 28 and igniting. The engine is mounted in an aircraft, Fig. 1 (not shown), as an auxiliary power unit for starting a main gas turbine engine (11) through shafting 16, (18) and a clutch (17). The motor 22, which may be electric or pneumatic, also acts as the starting motor for the auxiliary engine, driving the latter through a clutch 23 and shaft 16. The motor also drives an accessory unit 24. The obturating means 32 comprises a metal plate 33 hinged at 34 to the inner wall of the aircraft fuselage 10 and resiliently supporting a second plate 35 by springs 36. The plate 33 is actuated by a mechanism so that when motor 22 is switched on the plate pivots to the open position to allow the exhaust gas or air to flow through outlet 29 and aperture 30 in fuselage 10 to atmosphere. When motor 22 is shut off the mechanism pivots plate 33 so that plate 35 moves to the position dotted at 35a to shut off the outlet 29. Thermal insulation 31 reduces the risk of ignition of fuel vapour on contact with the exterior of the auxiliary engine.

Title: Improvements in or relating to the manufacture of double-walled glass articles
IPC: C03B23/13
Filed: 1925-04-23
Abstract: 243,230. Terrell, T. April 23, 1925. Forming vacuum flasks.-A machine for making vacuum flasks comprises means for positioning an inverted outer blank concentrically above an inverted inner blank, means for raising the inner blank into spaced relation with the outer blank, means for fusing the edges of the blanks together, and means for shaping the neck of the flask formed by the fusion of the edges of the blanks. Construction. The mechanism comprises two vertical shafts 19, 49, Fig. 1, which are journaled in bearings on a frame 1 and are rotated synchronously by a motor 2. The upper shaft 19, which is hollow, is connected at its upper end with a compressed air pipe 24, and at its lower end carries a chuck 30 which can be opened or closed by a lever 34. The lower shaft 49 is free to slide in its bearings and is lifted or lowered by a handle 56. A sleeve 61 slides on the shaft and is provided with a handle 62 by which it can be moved. A bracket 64, secured to the frame 1, supports a two-part mould 65 preferably made of graphite and provided with vent slots 65<1>. The mould supports slide horizontally on the bracket and can be moved by a lever 78 to a position where the mould closes around the neck of the flask. A core 84, supported by a. swinging bracket 97, can be moved below and raised into the neck of the flask. The core is made in two parts so that it can be caused to embrace the shaft 49. Gas burners are supported in such a position that their flames play on the neck of the flask. Operation. The method of making a flask is shown diagrammatically in Figs. 6-10. An outer blank A, which has the exhausting nipple 41 formed, is placed in the chuck 30, and an inner blank B is placed over the shaft 49 so that it rests on a cushion 49' secured to the shaft. The shaft is now raised so that it lifts the inner blank into the outer one, and is locked in position. The blanks are rotated synchronously by the motor, and flames from burners 82, 82' are adjusted to play on the outer blank. The glass softens and contracts and is drawn out by the weight of the lower portion of the blank, the separation of the excess glass being assisted by movement of the sleeve 61. The contracted portion of the outer blank meets and adheres to the lower end of the inner blank, thus forming the neck of the flask. The inner core 84 is then moved into the neck of the flask and the mould 65 is closed around the neck. Compressed air from the pipe 24, admitted to the chuck through the hollow shaft 19, passes through the nipple 41 on the flask into the space between the walls and forces the hot glass of the neck to take the shape of the mould. After removal of the mould and core, the neck is annealed by flames from the burners.

[Also in Group XIII] A switch for controlling heating apparatus, such as furnaces, stores, oil or gas heated boilers and the like, comprises a radiation absorbing member, a temperature compensating member,and a contactcarrying lever connected to said members at spaced points, differential expansion of the members causing the contact carried by the lever to engage a fixed contact. In one form, Fig. 1, the radiation absorbing member 1 and the compensating member 2 are supported in a block 3 and connected at 11 to the contact-carrying lever 10. The members 1, 2 are preferably of identical shape, size and material, and the former may have a black surface and the latter a reflecting surface, or may be screened by the member 1. The members are arranged opposite slits 32, 35 in a casing 31 which may be arranged opposite a hole in the wall of a furnace, Fig. 4 (not shown), so that the member 1 is exposed to radiation from the furnace. The arrangement is such that on ambient temperature increases, both members 1, 2 expand the same amount so that contacts 13, 14 remain open, whereas member 1 expands more than member 2 due to radiation, and the lever 10 is tilted to close the contacts. The latter are connected in series with a fixed contact 42 and a contact 41 carried by the pivoted cover 38 of an air inlet 37, which may be connected to the air supply for the furnace, the contacts 41, 42 closing when the air pressure is high enough. The air escaping through the slits 32 prevents entry of soot, &c. therethrough. In a modification, Fig. 2 (not shown), the members 1, 2 are helical, the lever 10 also being curved, and in a further modification, Fig. 3 (not shown), the lever is engaged at spaced points on opposite sides by two diaphragms.
