Title: Improvements in processes and apparatus for knotting pile threads in manufacturing carpets
IPC: D03D39/02
Filed: 1930-05-15
Abstract: 348,880. Pile fabric looms. EIBUSCHITZ, R. and SCHREIBER, H., 71, Hauptstrasse, Jõgerndorf, Czecho- Slovakia. May 15, 1930, No. 15014. Convention date, May 18, 1929. [Class 142 (ii).] In knotting pile threads into the warp of a carpet, the pile thread about to be knotted is coiled in one or more turns around a pair of warp threads shifted out of the plane of the warp and when thus coiled into a ring is seized by a pair of nippers passing between the two shifted warp threads whereupon the running pile thread is severed from the ring which is pulled through between the two warp threads and is cut through at the place seized by a head knife on the nippers. Displacers 8, 9 thrust forward a pair of warp threads 1x into a longitudinally slotted bush 5 rotatable in a beam 2, displaceable across the warp threads, by a rack 7 and pinion 6 on the bush when the rack is displaced in the beam 2. Pile threads 10 pass through guides 11 having hinged lower portions 16, and a selected thread is brought to the bush 5 by a lowering of the cord 14, by which its guide is connected to a plate of a Jacquard machine, and a forward movement of a slotted plate 17, the projecting end of the thread entering the longitudinal slot 3 of the bush and being gripped there by a spring clip 18 previously opened by a spreader 19. The bush 5 is now rotated to coil say three turns of the thread thereabout and so form a ring 10x, Fig. 4. A pair of pile thread nippers 20, 21 now advance beneath the bush 5 between the separated pair of warp threads and move upwards one jaw 24 passing through a slot 22 in the bush and entering the ring 10x and the other jaw 23 projecting through the longitudinal slot 3 to grip the ring. A slight movement of a frame 12 carrying the guides 11 or of the slotted guide 17 moves the end of the guide 11 away from the bush and permits weft cutters 25 to sever the thread whilst leaving a portion projecting from the end of the guide. The nippers now move downwards relatively to the bush and are withdrawn from the warp threads to pull the ring 10x into a Turkish knot, a knife edge 26 on the jaw 23 finally severing the thread to produce a tuft.

Title: Improvements in or relating to methods of applying a luminescent layer to the hollowside of a support having a rotation-symmetrical curved surface
IPC: H01J9/22
Filed: 1952-06-17
Abstract: A method of applying a luminescent layer to the concave side of a curved support having a rotation-symmetrical surface, particularly a surface in which a layer of photo-electrical material is subsequently applied to the luminescent layer for use in an X-ray image intensifier, by rapid rotation of the support about its axis of symmetry to distribute a quantity of a suspension of a luminescent substance in a suitable adhesive, applied to the support, in a layer of uniform thickness over the support, is characterized in that during rotation the support is heated, partial drying of the adhesive adhering to the grains of the luminescent substance taking place at a temperature lying between 45 DEG C. and 75 DEG C.  After settling of the luminescent substance from the suspension the speed of rotation and the temperature of the support is increased until the layer is dry and the adhesive hardens.  The speed of rotation may be so increased that some of the adhesive spills away leaving just sufficient to cover the luminescent substance.  After 2 or 3 hours the rotation is stopped and the screen is heated to a temperature of about 200 DEG C. at which temperature the adhesive, if for example a silicone, hardens completely in about 16 hours.  In an example a thin spherical aluminium plate, 160 mms. in diameter and having a radius of curvature of 200 mms., is secured to a horizontal rotatable disc in such manner that the axis of symmetry of the plate coincides with the axis of rotation of the disc and 12 c.cs. of a suspension of 240 grs. of a blue luminescent phosphor in 140 c.cs. of a silicone is used.

Filed: 1968-03-29
Abstract: 1,199,506. Revaporizing liquefied gases. AIR REDUCTION CO. Inc. 29 March, 1968 [29 March, 1967], No. 15233/68. Heading F4P. [Also in Division F1] Supply of liquefied gas e.g. oxygen to a vaporizing coil 16 delivering through a pressure regulating valve 14 to a consumer line 10 is provided by a group of series-arranged vacuum insulated cylinders 24, 25, 26 each cylinder except 26 having a dip pipe 28 connected by an ambient air heated flexible tube 36 to the gas space of the succeeding cylinder, whilst the dip tube 28 cylinder 26 is connected to the supply line 18 of coil 16, and each cylinder also has a bottom liquid withdrawal tube 42 leading to a vaporizing coil 44 having a shut off valve 34; the coil 44 of the last cylinder 24 being connected to the gas space of said cylinder 24 through open valve 34, a gas line 46 having open valves 56a, 58b and a pressure maintaining valve 48 which closes above 100 p.s.i. thereby maintaining gas pressure in cylinder 24 and also in cylinders 25, 26 by virtue of vaporization of a small flow of liquid through external ambient air heated flexible tubes 36 extending between cylinders 24, 25 and 26. In operation and assuming the liquid level in the first cylinder 26 to have fallen below the dip tube 28, the fall in gas pressure in cylinder 26 results in a relatively large intermittent flow of liquid from cylinder 25 to 26 until the level in 25 falls below the drip tube 28 whereon liquid flows from the last cylinder 24 to cylinder 25. When the last cylinder 24 is nearly empty and in order to continuously maintain liquid supply to coil 16 a connection 18a is made from a valved branch of the dip tube 28 of cylinder 24 to a line 181 leading to coil 16, a valve 32<SP>1</SP> in line 18<SP>1</SP> is opened and valve 32 in line 18 closed, the valve 34 in the connection 36 between cylinders 24, 25 is closed and the connections between cylinder 26 and line 18 and between cylinders 24, 25 and 26 are broken leaving cylinder 24 to maintain supply. New cylinders 51, 52 are then connected in series with cylinder 24 to form a second group of which cylinder 24 is the first and cylinder 51 the last, and the evaporator coil 44<SP>1</SP> of cylinder 51 is connected to the gas space thereof through a valve 56b, gas line 46 and valve 58a; valves 56a, 58b being closed. In the event of a pressure build-up in the gas line 46 downstream of valve 48 a valve 70 opens above 150 p.s.i. and relieves the pressure through coil 16. In a modification two groups of cylinders are arranged so as to supply the vaporizer coil alternately.

Title: Improvements in or relating to Gear Cutting Machines.
Inventor: BROWN PERCY
IPC: B23F5/14
Filed: 1917-10-23
Abstract: 129,331. Brown, P., and Bostock, F. J. Oct. 23, 1917. Gear-cutting. - Relates to machines of the rack-cutter type, and consists in indexing- mechanism which operates while the blank rotates and avoids the necessity for stopping the cutter at the end of the stroke. The tool slide 1, Fig. 2, is reciprocated in any usual way and carries the cutterblock, which is mounted on a spindle 22, as usual, so that it can be raised to clear the work during the return stroke. The cutter-block is moved slowly in one direction, and quickly in the other, by means of a screwed spindle 2, nut 3, and the differential and other gear shown. The spindle has keyed to it a helical wheel 14 in gear with a similar wheel 15 carried on a countershaft 16, Fig. 3, which is continuously rotated by the shaft 19. The wheel 15 can be driven by a friction clutch 20, or by a positive clutch put in gear when required. On the spindle 2 is loosely mounted a bevel-wheel 5 forming one member of a differential gear, the other members of which are a similar bevel-wheel 9 and a pair of pinions 11, carried on arms projecting from the spindle. The wheel 9 is carried on a sleeve 9<1> which rotates about an extension 10 of the spindle 2 and is locked and unlocked by the indexing-mechanism. Secured to the boss of the bevel-wheel 5 is a worm-wheel 6 continuously driven from the shaft 8. When the bevel-wheel 9 is locked, the spindle 2 is slowly rotated in one direction through the worm and differential gear, the friction clutch 20 slipping during such rotation ; but when the wheel 9 is free to rotate, the spindle 2 is driven rapidly in the other direction from the shaft 19 through the friction clutch and gear 14, 15.

Title: Improvements in or relating to sighting apparatus for use on aircraft and for like purposes
IPC: F41G3/22
Filed: 1938-05-24
Abstract: 559,939. Sights for use on aircraft. FAIREY AVIATION CO., Ltd., and HILTON, L. M. May 24, 1938, No. 15416. [Classes 9 (ii) and 92 (ii)] Relates to sights for use on aircraft for directing torpedoes or gun fire in which the line of sight is inclined to the line of fire to correct for movement of the target or the effect of wind on the projectile. According to the invention, two sighting devices are so coupled that the setting of one produces automatically a proportional setting of the other, such differential setting corresponding with the different angle of attack necessitated by avoidance movement of the target. In the form shown the normal sight bar 20 and the avoidance sight bar 19 are mounted coaxially on pivots 17, 16 on a circular frame 11 slidable transversely of the aircraft on bars 14, 15. The sight bars carry rollers 26, 25 respectively engaging in cam grooves 24, 23, Figs. 6 and 5 in a rail 22 mounted alongside the bar 15. The normal sight bar 20 is set to the required angular deflection for speed of target by moving the frame 11 along the guide bars and the sight bar 19 is thereby set to a smaller angle to allow for variation of the target position due to avoidance action.

Title: Loop-structured communication system
IPC: H04M9/02
Filed: 1974-04-08
Abstract: 1457058 Data transmission; looped systems INTERNATIONAL BUSINESS MACHINES CORP 8 April 1974 [30 May 1973] 15431/74 Heading H4P To reduce interruption time in a communication system arranged on a closed loop, which may comprise two channels, wherein signals normally circulate unidirectionally on the or each channel, switch units are arranged to terminate ends of selected loop sections and duplicate an incoming data stream which is transmitted bi-directionally at a first unit the two identical streams being monitored and synchronized by delaying the earlier stream at a second unit. The delay of the earlier stream is increased incrementally each sync. character arrival if the phase is less than one time unit difference, which is further adjusted successively by fractions of a time unit. A main loop and auxiliary loop may be separate wire pairs or separate time space channels. Normally data circulates unidirectionally on loop 11 to which interface units and terminals are connected, and oppositely on loop 13, the loops normally being independent but may be sectioned and loop ends mutually connected in fault conditions by units 21. Loop controller 19 generates a sequence of empty frames which can be seized and used for transmission by any terminal. If failures are recognized early, switch over can be made in controlled manner to avoid interruptions. Each switch unit 21 comprises sync. circuitry 23, receiver/transmitter 25, 27, and further circuitry (see Fig. 4, not shown) for connection or disconnection of power supply. Sync switching circuit 23 comprises switches S11, S12, S21, S22 by which main loop sections 29, 31 and auxiliary sections 33, 35 may be selectively connected and controlled by unit 39, which receives commands either via main loop and Rec/Trans 25 or auxiliary loop through Rec/Trans 27. Discriminator 41 detects time difference between frame arrivals on the loops and variable delays 43, 45 controlled by 39 incrementally vary the delay to provide near coincidence of the two streams. The discriminator is described with reference to Fig. 7 (not shown). The beginning of each frame has a sync. pattern for synchronizing purposes and clock signals are derived from the data stream by unit 39. For fine adjustment, monostable circuits 83, 85 and AND 87 are provided. When phase difference has been reduced to less than one bit period, loop controller shifts leading end of the frames on the auxiliary loop fractions, e.g. 1/10th bit period both positively and negatively so that time difference approximates to zero. Delay unit (Fig. 8, not shown) comprises a shift register (95) operating in conjunction with a control register which selects one of several output stages from register 95 and hence the delay.  The switch units may facilitate fault location but this aspect is not particularly described.
