Abstract: 1476144 Pulse controlled shutter/diaphragm WEST ELECTRIC CO Ltd 29 Oct 1974 [15 Nov 1973 28 Dec 1973] 46755/74 Heading G2A A combined shutter/diaphragm is operated by a stepping motor, first to open to an aperture determined in accordance with ambient brightness and then to close after an interval determined by the pre-set aperture and ambient brightness. A pulse generator 39 feeds a counter 109 which gives a step-wise sequence of output voltages which are compared in differential amplifier 146 to the ambient-brightness dependent voltage determined by photo-resistor 105. Thus the number of pulses controlled by ambient brightness, are passed via amplifier 124 to step open the diaphragm/shutter blades by stepping motor 1. The diaphragm is thus pre-set in accordance with ambient light. The pulses are also counted by ring counter 128 which successively cuts out various resistors 136-8 by switching short-circuiting transistors 142-4. Thus the voltage at junction 134, 135 now represents the diaphragm opening and is used as one parameter in a CR timing circuit. The other parameter, ambient brightness is determined by photo-resistor 104 (R) through which C, capacitor 131, is charged. Capacitor 131 is shorted by transistor 130 until the latter is opencircuited at the beginning of the timing period by switch 102 linked to the "tape" button. The CR circuit described opens amplifier 149 after the appropriate time and this then feeds closing pulses to stepping motor 1. Two alternative shutter/diaphragms are disclosed. In Fig. 3 (not shown) a two bladed version has the aperture between a terminal pivot and the pre-end of each arm which carries a pin engaging a slot in a cam driven by the stepping motor. In Fig. 4 (not shown) there are three pivotted blades opened and closed by pairs engaging rotary slots and the stepping motor which is coaxial with the diaphragm/ shutter has an annular rotor through which taking light passes to the photographic emulsion.

Title: Separating poly(ª-monoolefines) from solutions of the same
Inventor: BILLET REINHARD
Filed: 1962-12-13
Abstract: Poly-(a -mono-olefines) are separated from solutions containing 1 to 20% by weight of the polyolefine dissolved therein by evaporating solvent from the solution at temperatures between 30 DEG  and 240 DEG C. and pressures between 1.1 and 40 atmospheres until the solution contains 50 to 80% of polyolefine, then reducing the pressure to between 760 and 10 mm. of mercury, with or without increase in temperature, and removing the solvent thereby vaporized. Preferably, if the initial solution contains 1 to 15% of poly-(a -mono-olefine), the solvent is evaporated in two or more evaporators up to a poly-(a -mono-olefine) content of 50 to 80% by weight.  In the first evaporator the solvent is preferably evaporated at temperatures of 10 DEG  to 20 DEG  C. above the solubility temperature of the poly-(a -mono-olefine) in the solvent used, and the boiling temperature in the second evaporator is preferably higher.  The solvents used are linear or branched aliphatic, cycloaliphatic or aromatic hydrocarbons having boiling points at standard pressure of 35 DEG  to 220 DEG  C. such as pentane, hexane, heptane, octane, nonane, gasoline fractions, cyclohexane, benzene, toluene and xylene.

A linkage for converting angular movement of an input shaft 12 to linear movement of an output rod 38 pivoted to an intermediate shaft 22 parallel to the input shaft 12 by an eccentric pin 36, comprises a bifurcated lever 12a rigid with the shaft 12 and movable between stops 40, 42 in a housing 10, a block 20 on a pin 18 pivoted to the lever 12a being slidable in a longitudinal channel 28 of a lever 22a rigid with the intermediate shaft 22, such that when the lever 12a is midway between stops 40, 42 the pin 18 is close to the shaft 22 axis. Initial movement of the lever 12a from the mid-position shown (Fig. 2) causes rapid movement of the lever 22a to a maximum displacement. Further movement of lever 12a causes reversal of lever 22a and a slow movement towards the midway position. Thus the full displacement of lever 22a, and hence of the rod 38, takes place in approximately the initial eighth of the lever 12a travel. The pin 18 extends through slots 30 in the sides of the lever 22a. The linkage is used in a feedback mechanism controlling a servo valve in an aircraft control surface actuating system.

Abstract: 1,007,806. Coiling. E. KUNZ. Dec. 4, 1963 [Dec. 4, 1962], No. 47949/63. Heading B3E. A spring coiling machine in which the spring wire to be coiled is fed by rollers against fingers disposed on rocking levers which bend the wire to the required radius and coil it helically, the rollers being driven by a crank drive and free wheel clutches is characterized in that two rotary movements advancing the spring wire are communicated to the feed rollers on each full revolution of the crank pin. The machine comprises a housing 1 on which is mounted a coiling head 2 having coiling tools on its two outer sides to produce left and righthand springs simultaneously. Feed rollers 3, 4 feed the wire against fingers 9, 10 mounted on rocking levers 6, 7 to coil wire in a known manner. The rollers are motor driven through chains 18, 19 and a worm gear 20 on a shaft 21 bearing a disc 22 on which a crank pin 24 is radially movable within a slide guide. The pin engages a block 26 secured horizontally to two parallel endless chains 29, running over wheels 27, 28, the former being fixed on a shaft 30 which bears two free wheel clutches 32 whose inner rings are connected to gears 33. Rotation of the disc 22 produces upward movement of the block 26 which drives the pairs of rollers 34 via chains 29, clutch 32, an intermediate gear 35 and a reversing gear 36 whilst downward movement drives the rollers 34 via chains 29, clutch 31 and gear 35 to impart two rotary movements to the rollers during one revolution of the crank. The wire feed is adjusted by varying the throw of the crank pin by rack and pinion means (not shown). The rocking levers 6, 7 are actuated by cam faces 44 of templates 43 disposed on a push rod 40 coupled via a guide 41 to a crank pin 42 disposed on the worm-wheel drive shaft. A disc 14 driven by a chain 45 actuates a locking lever 13 on which is disposed a cutter 12, co-operating with a central cutter 11 to sever the coiled spring. A control cam 14a causes the severing to take place at a dead centre position of the block 26, i.e. when the rollers 3, 4 are stationary. Pitch controllers 15, 16 are provided to determine the coil pitch.

Material to be separated is introduced into a vessel at a point between an upper vertical upward current classifying chamber 16 and a lower inclined chamber 15 of smaller cross-sections in which falling material accumulates to be scoured by the rising washing fluid. As shown in Fig. 1 the bottom chamber is defined by outer and inner conical walls 17, so material to be washed is introduced with carriage water into a cylinder 22 surrounding a clean water supply line 28. The material settles downwardly over a cone 41, the heavies with some entrained lights falling on to wall 17 of the lower chamber the lights being scoured back up into the upward current classifying chamber 16 by the higher velocity of washing water rising up from its inlet 51. A perforate screen 19 at the top of the upward current classifying chamber regulates and distributes the flow of washing water. The washing water and material may be supplied under pressure so that the water and heavies ejected from the bottom and the water and lights ejected from the top of the device each drive a cyclone to extract and recirculate the washing water, Fig. 2 not shown. Fig. 3 shows a version of the device in which the material to be separated is carried in the main stream of washing water taken from a mixing tank 38 and pumped at 45 to a cyclone 47 on the device. The cyclone 47 separates out a concentration of the material and delivers the separated water to the bottom of the device at 51 from where it rises as washing water. The top of the device may be open, Fig. 4 not shown, with the light fraction overflowing a weir and the material to be washed admitted into an open cylinder surrounding the water inlet pipe. In such an impressurized system the water is reclaimed by screening. A pneumatic version of the device is shown in Fig. 5 in which a hopper 56 receives the material to be cleaned, the material falling into a spreading cone. The lower chamber 15 has riffles 62, 63 to promote scouring of the accumulated heavies. The spreader cone and associated conical portion defining the lower chamber 15 may be streamlined along with the outer wall 17, Fig. 6 not shown. Instead of comprising bodies of revolution the device may comprise an upper cylindrical portion 16, Fig. 7, a deflected narrower portion 15 in which the heavies accumulate at 18, and an input shoot 12 at the junction to admit material to be separated.
