Abstract: 644,714. Knitting - machines. HACKETT, G. A. April 22, 1948, No. 11159. Convention date, May 23, 1947. [Class 74 (ii)] A device for detecting faults in a fabric knitted on a warp machine comprises a finger 3 pivoted to a lever 5 which itself is pivoted to the frame 2 of a casing 1. A weight 7 is carried by the lever 5 and urges a pin 8, carried by the finger 3, through a slot in the casing 1 into contact with the fabric F. Two fingers 3 and two levers 7, and associated parts, are mounted in each casing 1 and the fingers extend in opposite directions so that when the casing is reciprocated beneath and across the fabric, for the width or part of the width of the fabric, the finger inclined in the direction of movement detects a gap in the fabric by the pin 8 extending through the gap. Continued movement of the casing causes the finger 3 to swing about its pivot so that its lower end 10 makes contact with a spring 11, incorporated in an electric circuit, to operate a relay which actuates an alarm and stops the machine. Alternatively the alarm may be operated without stopping the machine. The casing 1 is reciprocated by means of a double threaded shaft engaged by a tumbler in a block mounted on the shaft, the block being connected to the casing 1. A cover strip 36 may be associated with each slot to render the device inoperative. A number of devices may be connected together so that each reciprocates across a portion only of the width of the fabric.
Patent GB-422906-A (GB)
Title: Improvements in and relating to signalling systems, such for example as television systems
IPC: H04N5/16
Filed: 1933-04-13
Abstract: 422,906. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and WILLANS, P. W., 18, Park Hill Road, Hampstead, London. April 13, 1933, No. 11204. [Classes 40 (iii) and 40 (v)] The direct - current components of a television signal which are lost in an amplifier, are re-inserted by the operation of recurrent maximum or minimum signals, for example, synchronizing signals. The positive synchronizing signals on the grid of a valve 6 cause grid current to flow to give a charge to a condenser 7 which leaks away through a resistance 8. The grid potential thus becomes such that grid current just flows in response to the synchronizing signals. The picture signals are more negative and do not affect the average charge on the condenser. The time constant of the condenser and resistance is short compared with that of the circuits of the preceding amplifier. Since some loss of the direct-current components is inevitable, the anode resistance 9 is shunted by a circuit 34, 35 to attenuate the upper frequencies. According to modifications : the synchronizing signals are negative and a diode rectifying valve is used, Figs. 10 and 12 (not shown) ; the output of a high-impedance amplifier works into a shunt inductance across which are connected a rectifier and a low resistance in series, Fig. 11 (not shown).

Title: Improvements in or relating to a mechanical assist device
IPC: G05G7/04
Filed: 1962-03-23
Abstract: 997,046. Clutch control; spring power-storing mechanism. DANCE CORPORATION. March 23, 1962 [Jan. 5, 1961], No. 11287/62. Headings F2C, F2L and F2S. A device assisting a vehicle operator in rotating a lever to disengage a normally engaged spring-loaded clutch, acts upon the lever after the lever has undergone an initial, predetermined movement. The device shown in Fig. 4 is for use with the double clutch arrangement shown in Fig. 3 and having clutches which are selectively disengageable by movement of a lever 92 to either side of a central (clutch engaged) position. Movement of a throw-out collar 82 to the left acts through a lever 77 to release a clutch 74, and movement to the right acts through a lever 75 to release a clutch 76. The device comprises a fixed casing 25 and an axially slidable rod 41 connected to the clutch lever at 104. In the clutch engaged position (shown), a compression spring 50 is held preloaded be tween a bushing 38 reacting against balls 86- which are retained by a groove 88 in the casing, and a bushing 42 held against balls 54 which are retained by a groove 56. During declutching a groove 90 or 60 in the rod 41 is aligned with the balls 86 or 54, which are thereupon cammed into this groove and out of the groove 88 or 56, so that further declutching movement is assisted by the spring 50. In a modification of this device for use in a single clutch arrangement, the bushing 38 reacts against a fixed flange of the casing. In another modification, the device forms part of a conventionally operated hydraulic slave cylinder, the bushing 42 being dispensed with, the spring reacting against the end of the casing, and the rod 41 to the left of the balls 86 being formed with a piston. In the modification shown in Fig. 9, a return spring 192 is provided to assist clutch engagement after the balls 54 have re-entered the casing groove, the rod 41 being returned to its fully engaged position by the spring 192 which presses against a pin 194 passing through slots in the rod and reacting against the bushing 42. In the embodiment of Fig. 6, a tension spring 140 is connected by a link 150 to a cam follower 146 which extends through an L-shaped slot 144 in a hand-operated clutch lever 142. In the clutch engaged position of the lever the cam follower 146 is disposed in a circumferentially extending leg 145 of the slot in lever 142 and is retained in a notch in a stationary member 154. On moving the lever 142 anti-clockwise, a radially extending leg of the slot 144 is brought into line with the follower 146 which is then cammed out of the notch and acts to aid the anti-clockwise movement. In the modification of Fig. 8, a roller 168 is loaded by a spring 140 and co-operates with a clutch pedal 164. In the engaged position of the pedal the roller is received in a detent 170 in an adjustable stationary member 172. Clockwise movement of the pedal to declutch cams the roller into a detent 182 in the pedal and thereafter the spring assists the declutching movement.

Title: Casting steel ingots
IPC: B22D35/04
Filed: 1975-03-14
Abstract: 1482088 Casting steel ingots BRITISH STEEL CORP 14 March 1975 [15 March 1974] 11643/74 Heading B3F Steel ingots are cast with a low content of non-metallic inclusions by introducing a gas into the runner system together with the molten steel when the runner supplies steel to the mould from an upwardly facing exit into the bottom of the mould. The gas may be inert, i.e. Ar, N or reactive to form a flux with the steel constituents. The steel may be fluxed during or after casting, the flux containing at least one of Ca tetraborate, Ca borate, Na carbonate, Ca fluoride, hydroboracite, lime or magnesia. An ingot mould 10 rests on a recessed upper plate 11 on a base plate 12. A refractory lined -runner 14, 15, 16 is machined in plates 11 and 12. A gas conduit 17 enters vertical runner 14 just below the top of the vertical portion of runner 14 before it enters recess 13. In use, molten steel 20 is poured into runner 16, passing through cross runner 15 into runner 14 and into the recess 13 thence into mould 10. During the pouring or as soon as the pouring ceases, a gas is passed from supply 18 into conduit 17, so that bubbles of gas enter the runner and then ascend into molten ingot. The gas bubbles tend to follow the pattern indicated by the arrows, and then exert a scrubbing effect on the solidifying metal. The gas flow rate and pressure are adjusted to give visible signs of agitation in the ingot, and the input tube is of such a size to give generally coarse bubbles. Since runner 14 is centrally located in the mould, the action of the gas is relatively uniform over the whole ingot area. The process, apart from scavenging the ingot, also produces a reduction in oxygen content when an inert gas is used. In a modification, the gas-flow may be started prior to casting to flush the runner of oxidizing gases, and in a further modification, recess B may be omitted, and cross runner 15 may be recessed into the upper surface of the base plate 12.
