The pumps are worked from a cam adjustable axially for regulating. The angles of the cams are set out in the Specification.
Patent GB-775369-A (GB)
Title: Improvements in and relating to the production of viscose
Inventor: ENTWISTLE DONALD
IPC: D01F2/08
Filed: 1954-06-15
Abstract: A process for ripening viscose comprises feeding viscose continuously to a ripening zone which is open to the atmosphere and which is maintained substantially full of viscose, continuously advancing the viscose through the zone while avoiding the formation of stagnant pockets of over-ripe viscose, filtering the ripened viscose, and then continuously de-aerating the viscose.  The process may, if desired, be carried out either a few degrees above or below the normal ripening temperature, preferably a few <PICT:0775369/IV(a)/1> degrees above.  If the ripening process is carried out at such a slightly elevated temperature the viscose should thereafter be cooled, and this may be done during the de-aeration step or in a heat exchanger. If desired, the ripened viscose may be de-aerated both before and after filtration.  A suitable apparatus comprises a series of open-topped tanks 20, 21, 22, 23, two linefilters 24, 25, and a continuous de-aerator 26, part of which only is shown. Each of the tanks has a supply pipe 27, 28, 29, 30 respectively, a discharge pipe 31, 32, 33, 34 respectively, and a gate-type stirrer 35 which may be rotated by a shaft 36.  Viscose is pumped from a mixer (not shown) to tank 20, whence it passes, impelled by pump 37, to tank 21, and thereafter to tank 22.  On leaving tank 22 the viscose passes through line filter 24 to tank 23, and thence through line filter 25 to de-aerator 26.  Tanks 20 and 21 are generally maintained substantially full, tank 22 about a third full, and tank 23 about two-thirds full.  The gate-stirrers are rotated to give lateral agitation of the viscose with a minimum of vertical mixing.  If desired, a second continuous de-aerator may be inserted between tank 22 and filter 24.  If the viscose has been ripened at a temperature above the normal, it may be cooled by passing the viscose leaving tank 23 through a heat exchanger, or by suitably adjusting conditions in the deaerator 26.  In another apparatus which is described, the viscose is made to pass from tank to tank by displacement.

Filed: 1966-04-22
Abstract: 1,116,752. Juke-boxes. WURLITZER CO. 22 April, 1966 [26 April, 1965], No. 17812/66. Heading G5R. [Also in Division F2] A two-speed phonograph drive is adjusted automatically according to whether a 45 r.p.m. record having a relatively large centre hole or a 33<SP>1</SP>/ 3  r.p.m. record having a smaller centre hole is put on the turntable. The gear com. prises a stepped shaft 114 of an electric motor 108 engaged by a rubber-tyred wheel 122 fast with a pulley 178 which is connected by two O-ring belts to a pulley 40 on the turntable shaft 46. The wheel 122 and pulley 178 are rotatably mounted on a stud carried on a bellcrank lever 160 which is spring-biased to a position in which the wheel 122 frictionally engages a step of the shaft 114. When the phonograph is inoperative a shaft 22 is turned to an anti-clockwise position in which a pin 196 actuates a lever 182a and link 188a to pivot the bell-crank lever 160 to lift the wheel 122 out of engagement with the shaft 114. On starting a playing cycle, the shaft 22 is turned clockwise to release the wheel 122 for engagement with the shaft 114. The wheel 122 is shifted axially to select the desired step of shaft 114 by a second bell-crank lever 142, Fig. 5, which shifts the bell-crank lever 160 axially along its pivot and is spring-biased to a position in which the wheel 122 engages the larger diameter step of the shaft 114 appropriate to 45 r.p.m. records. The turntable shaft 46 carries record clamping mechanism and is shifted axially by a facial cam on the shaft 22 acting through a lever 60 acting on the end of the shaft 46. A spindle 48 concentrically mounted within the shaft 46 operates record centring mechanism which enters the hole of a 45 r.p.m. record but not that of a 33<SP>1</SP>/ 3  r.p.m. record, the spindle 48 being shifted axially by a cam 34 on the shaft 22 acting on a lever 72, Figs. 2, 2a, to which is pivoted a second lever 73 bearing on the end of the spindle 48. The lever 73 is spring biased towards the lever 72, but if the spindle 48 engages the 33<SP>1</SP>/ 3  r.p.m. record the arms 72, 73 move apart to operate a switch of a relay 102 which energizes a solenoid 128 to pivot the second bell-crank lever 142 and thereby shift the first bell-crank lever 160 and the friction wheel 122 axially to register with the smaller diameter part of the motor spindle 114. At the end of a playing cycle the shaft 22 turns anticlockwise so that the pin 196 lifts the friction wheel clear of the motor shaft 114. The relay is held " on " by a catch which is released when the shaft 22 is turned anti-clockwise, so that the solenoid is de-energized at the end of the cycle and the wheel 122 is shifted to register with the larger diameter part of the motor shaft.

Abstract: 357,136. Microphotographs of books. TIPECSKA, G. and MACH, L., 2, Schraudolfstrasse, Munich, Germany. June 13, 1930, No. 18193. [Classes 97 (i), 98 (i), and 98 (ii).] A lantern slide 28, Fig. 10, having microscopic images of the pages of a book or other matter with marginal indexes on the sides is made by first making a negative on a reduced scale and reproducing this negative with further image reduction to microscopic proportions. A slide holder is described having key-controlled means for stepping the slide in two transverse directions and scales for approximately positioning any image in a central aperture for projection. Apparatus described for making the slide comprises a camera 1, Fig. 1, for making the negative. The sensitive plate 5 is slidably mounted in a second slide which is adjustable in a transverse direction. One or a group of pages are successively mounted on the holder 2. The negative so produced is further reduced to obtain the desired micro-images by a camera 14, Fig. 5, in which both the negative 5 and sensitive plate 13 are mounted to move in two directions relatively to the lens 19, synchronous movement being obtained by a pivoted arm 24. The microslide holder, Figs. 12 and 13, comprises a base 34 with a central aperture for projection, a frame 36 vertically movable on the base, and a slide-holder frame 37 transversely movable on the frame 36. The slide is held on the frame 37, by springs 39, against an angle-piece 40. The frame 36 is urged downwards by a spring head 42 and is stepped by a key S which controls a double pawl escapement engaging a fixed rack 43 on the base. The rack 43 also carries a scale 45 over which a scaled arm 46 on the slide holder 37 moves. The transverse movement of the slide carrier frame 37 on the frame 36 is obtained by a pinion 44 and rack movement, operated either from the key Z through a pawl and ratchet movement 49, 50, or by a hand knob 41 on the pinion shaft. The position of the slide 28 vertically and horizontally is determined by the scales 45, 46 which correspond to the co-ordinate marginal indexes on the slide.
