Abstract: 1,167,065. Luminescent screens. TEKTRONIX Inc. 22 May, 1967 [31 May, 1966], No. 23619/67. Heading H1D. A combined, direct viewing storage target and fluorescent screen 10 comprises a support 12, a conducting layer 14 and an array of alternate phosphor regions 16, 18 capable of bi-stable storage and non-storage respectively. The target comprises storage dots 16 arranged in holes in a phosphor layer 18, on a light transparent support 12. A stored pattern in the dots and a trace in layer 18 is produced by a high-velocity electron gun 22 and a flood electron gun 24 when a suitable D.C. voltage is applied to the layer 14. This voltage can be varied for erasing or non-storage operation and the layer can be divided into separate areas to which different voltages can be applied. The layer 14 may be replaced by a light reflecting Al or Ag layer on layer 18 with perforations corresponding to the holes. The screen may comprise a phosphor layer sufficiently thin to be capable of storage covered with dots of the same or another phosphor, the greater thickness of the dot and layer preventing storage; alternatively the layer may be covered with a perforated light-reflecting layer which prevents flood electrons reaching the phosphor and hence storage, except beneath the perforations. The support may be covered with storage and non-storage phosphor dots between which extends the conducting layer.

Title: Circular knitting machine
IPC: D04B9/02
Filed: 1972-05-23
Abstract: 1349692 Knitting-machines ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 23 May 1972 [18 June 1971] 24068/72 Heading D1C In a circular knitting machine quality control is achieved by raising and lowering the needle cylinder 27 by the action of a cam surface 33 on a drum 22 which acts through a lever 35 the drum being racked by a pawl 29. The pawl 29 is pivoted at 28 on a lever 24a which is fast on a pivot pin 23 along with a pin 24. A lever 20 having a pin 19 is free to rotate about pin 23. When a command from a pattern chain causes a Bowden cable 5 to move a lever 11, a spring 30 moves the pawl into contact with the teeth 32 and at this point the, lever 24a begins to rotate on the pin 23 causing the pin 24 to move pin 19 into slot 18 on lever 11 and cam follower 25 into contact with the cam 26 on the needle cylinder. As the needle cylinder rotates cam 26 and spring 30 cause upward and downward motion on the pawl 29. If it is desired to stop rotation of the drum 22 whilst still moving the pawl then a tooth may be omitted from the rack 32. A further stud on the chain controlling the cable 5 causes it to move a further increment, the pin 19 to move into the notch 38 and the pawl to move down below the point at which the tooth is omitted and hence the drive to be continued. A segment 21 on the drum 22 causes the lever 20 to move to reset the mechanism to its original position when the cable 5 is released.

Abstract: 415,592. Winding-bobbins in machines for twisting at delivery. HOUCK, W. C., 18, Belsitostrasse, Zurich, Switzerland. Sept. 8, 1933, No. 24900. Convention date, Sept. 9, 1932. [Class 120 (ii).] A driving-device for the winding-bobbins of machines twisting at delivery in which, for the purpose of maintaining the thread speed constant, besides compensating gears which diminish automatically the number of revolutions of the bobbins, driven without the use of friction rollers, and of the traverse guide cam with increasing diameter of the bobbin and are adapted at the same time to diminish the stroke of the traverse guides, there is provided also a gear train for varying periodically the revolutions of the traverse guide cam and of the bobbin in the laying of each layer, an element of this gear train being adjustable proportionately with the alteration of the ratio of maximum to minimum diameter of the winding which accompanies increasing diameter of the bobbin. The machine is driven by belt or motor through an infinitely variable speed gear 1, gears 2, shaft 3, slotted disc coupling 5 6, shaft 4 and gear train 13-16. The traverse cam 10 is driven through a gear train 7-9 from shaft 4. A shaft 18, carrying a bevel wheel 21, is driven by adjustable ratchet gearing V, one element of which incorporates a sun-and-planet reduction gearing with a high reduction ratio. The bevel wheel 21 drives bevels 22, 23, 24, which operate, respectively, through screwed spindles 25, 26 and shaft 27 to control the reduction in stroke of the traverse mechanism, the degree of alignment of the coupling 5, 6 and the variation of the infinitely variable speed gear 1. With the three devices enumerated, conical bobbins with convergent ends 17 are stated to be formed at uniform thread speed. To produce bobbins as shown in Figs. 7 or 8, it is necessary, respectively, to interrupt the action of the screwed spindle 25, or to place the coupling 5, 6 into alignment ; while to produce cylindrical bobbins these conditions are observed together. On breakage of the yarn, a lever 46, governed by another lever 52 over the end of which the tensioned yarn passes, moves to disconnect a driving- clutch 45 while at the same time the unwinding- bobbin 49 is lifted by a lever system 47, 48 from its driving-cone 50.
