Title: Straight-bar knitting machines
IPC: D04B11/06
Filed: 1971-05-05
Abstract: 1326312 Knitting-machines SCHUBERT & SALZER MASCHINENFABRIK AG 5 May 1971 [29 May 1970] 13118/71 Heading D1C A straight-bar machine has a needle selection device controlling loop transfer or needle pressing controlled by independent pattern and selvedge controls. The selection device includes jacks 81, Fig. 2, raisable for pressing the needles, or preventing selvedge or lace points engaging the needles. The jacks are controlled by draw hooks 10. The hooks are movable by draw bars 30, 300, Figs. 2, 3 respectively, with which they can be engaged by a pattern control M. A selvedge control K overrides the action of the pattern control on the hooks. Figures 1, 2. The pattern control M includes a punched tape PM turned by an indexed pattern drum 60. Sensing pins 20, 20' lower the hooks 10, 10' selectively onto the bars. A bluffing plate 603 covers the tape when the selvedge control is in action. In the selvedge control K, a punched tape PK, which also controls general operation of the machine, is sensed by pins 2, 2'. Pivoted elements 5, 5' are thereby selectively moved out of the path of a raised part 6' of bar 6. Draw hooks 1 are thus selected to engage or miss the draw bar 3. The hooks operate bluffers 14 for a pawl 13 which turns screw 11 of the yarn carrier stops. A second screw 110 driving the frame 180 of the selvedge selector 7 is driven from screw 11. The selector acts on the hooks 10, 10' via elements 71 when the frame is rocked. A similar selector 9 is provided to ensure the margins of the fabric are pattern free when fashioning is not carried out. Hooks 10, 10' of the selector device W may be lowered by the pattern control, or raised by the selvedge control to engage the draw bars 30 below or above respectively. The hooks, acting via wires 40, slide lifting jacks 80 in a pivoted bed 800, and which in turn raise or lower jacks 81. Operation: If a jack 80 is moved by pattern control so that jack 81 drops off butt 806 the needles are mat pressed and form a tuck loop in the knitting cycle; during a fashioning cycle the lace points are free to make a transfer. Selector 9 may be in operation at the margins. During fashioning the selector 7 is rocked by follower lever 72 so that the hooks are raised to engage the draw bars so that they and jack 80 are pulled left. The selvedge points are thus free to pick up and transfer loops. Figure 3. The pattern control M is similar to that shown in Figs. 1-2. The selvedge control comprises combs 70, 90 carried on a frame 181 and engaging selector elements 74. The frame is rocked by arms 185 on a shaft 186 oscillated by levers (700, 903, Fig. 4, not shown) engaging a pin wheel (188) fixed to the shaft. The selectors are attached by wires 744 to one end of levers 741 which act on the wires 40 of the selector device. The operation of the device is similar to that of the first embodiment, the selector device transmitting movement to a jack (83, Fig. 5) having two working butts (806, 830). The jacks 83 may be moved at the dictates of controls by electromagnets having two working strokes.

Title: Improvements in or relating to photo-electric cells
IPC: H01J40/06
Filed: 1927-05-16
Abstract: 271,116. Westinghouse Electric & Manufacturing Co., (Assignees of Zworykin, V K.). May 15, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Vacuum tubes.-Photo-electric cells are provided with light-sensitive metal by immersing the glass envelope 5 of the cell, freed from oxygen and containing a heated cathode 8, in a fused salt 3 maintained at a positive electric potential relatively to the cathode 8, metal ions from the salt 3 replacing corresponding metal ions in the glass and these latter ions being liberated as the metal in the container 5. The glass and salt are chosen so that the ions from the salt do not alter the structural homogeneity of the glass when they replace the ions in the glass : in introducing potassium, fused potassium nitrate and a glass containing potassium, less than 1 per cent of lead, and no sodium are used. whilst in introducing caesium or rubidium, the glass is preferably such that these metals are the only metals replaced by electrolysis. The salt 3 such as anhydrous potassium nitrate is fused in an iron crucible 1 heated by a coil 4 in heat-insulating material 2 or by a Bunsen burner. The envelope 5 is supported by a clamp 11 pivotally adjustable on a verticallyadjustable horizontal arm 12 and is evacuated by a pump to a pressure of 10<-5> mm. or filled with inert gas such as argon. The cathode 8 is heated to incandescence to emit electrons by current from a battery 24 or a transformer supplied from the source of current for the coil 4. The salt 3 is maintained at a temperature of 335‹ C., and a battery 25 in series with a current meter 27 for determining the amount of potassium produced maintains the crucible 1 positive. Alternating current may be used instead of the battery 25, the cathode 8 acting as a rectifier. Potassium ions reaching the inner surface of the envelope 5 are neutralized by electrons from the filament 8 and the potassium vaporizes and may be condensed by a cooling coil 21 to form a sensitive deposit 22 in contact with a lead-in wire 6. The deposit 22 may be activated with hydrogen to form the hydride. A prior publication of a similar method of introducing sodium into thermionic tubes is referred to.
