Abstract: 1383450 Crystallizing apparatus INSTITUT FRANCAIS DU PETROLE 28 March 1973 [31 March 1972] 14872/73 Heading B1G A crystallizing apparatus comprises a substantially vertical elongated enclosure of which part is divided into adjacent compartments by plates integral with the walls of the enclosure. The plates have cut-out parts from centre to sides less in area than half of the area of a horizontal half-section of the enclosure and through these cut-out parts a vertical rotatable shaft passes. In each compartment are at least two blades attached to the shaft and rotatable therewith, and another blade located between these two rotatable and fixed to the wall of the enclosure. The apparatus also includes means for supplying and withdrawing liquids to and from the enclosure. The Figure shown is a three dimensional view of the compartments where 1 is a cylindrical enclosure, 3 is a rotatable vertical shaft, 5 are the blades attached to the vertical shaft passing through compartments formed by plates 2, and 4 are the blades attached to the walls 1, but staggered through 180‹ between adjacent compartments. In use crystallization is carried out in the apparatus by cooling a liquid mixture of at least two components by direct heat exchange with an immiscible liquid coolant of different density to the solution by circulating it counter-current to the mixture. Two forms of apparatus are described wherein the crystals formed are either heavier than the liquid mixture or lighter than the latter. The specification includes two examples of separating para-xylene from a mixture consisting of para-, ortho-, and meta-xylene, and ethylbenzene using as the liquid coolant an aqueous solution of lithium chloride.

Title: Improvements in apparatus for delivering molten glass and shaping and separating thesame
IPC: C03B7/02
Filed: 1921-05-30
Abstract: 175,949. Owens Bottle Co., (Assignees of Cramer, A. N.). Feb. 23, 1921, [Convention date]. Delivering molten metal.- In apparatus of the reciprocating-plunger type for delivering molten glass from an orifice, means are provided for manually adjusting the movements of the plunger during operation, for shearing the extended metal, and for timing and adjusting the shearing mechanism both simultaneously with the plunger and also independently. The plunger 37, Fig. 1, works in a boot 26 extending from the wall of the furnace and is carried by a yoke reciprocated by a lever 48 and cam 47. The mean position of reciprocation can be adjusted during working by raising or lowering an arm 52, Figs. 1 and 22, bv means of a handwheel 59 connected by a universal joint 60 to a screwed rod 55. The length of the stroke can be adjusted by varying the position of the fulcrum 49 of the lever 48, and the character of the stroke can be varied by the cam 47, Figs. 1 and 17, which is formed with three relatively adjustable parts 61. 62, 63. The portion 61 effects an initial rapid upward movement of the plunger, which is succeeded by a pause due to a rest portion 65 and by a slower upward movement due to the portion 62.- A second rest portion 66 allows the plunger to pause at the top of its stroke, and the final portion 63 allows the plunger to descend under its own weight. The cam 47 is rotated from driving shafts 111, 116, Figs. 1 and 10, through the intermediary of a worm-wheel 117, 118 and a chain drive 119, 120. The shearing mechanism comprises pneumatically-operated shears 82, Figs. 18 and 19, mounted beneath the boot and having cutting-edges 109, 110 adapted to grip the metal at four points simultaneously. A frame 86, upon which the shearing mechanism is mounted, is pivotally connected to the boot so that the mechanism can be swung down to permit the shears to be changed or adjustments made. The operation of the piston 88 driving the shearing mechanism is controlled by a distributing-valve within a casing 93, Figs. 9 and 10, which is actuated through a lever 96 from an adjustable cam on the shaft 100. The sprocket-wheel 119 on the ends of the shaft 100 is slightly adjustable by means of screws 147 so that an earlier or later operation of the plunger relative to the operation of the shears may be effected. To permit of adjustment of the timing of the plunger and shears relatively to the moulds 112, Fig. 1, which are carried on a table 113 revolving in fixed relationship with the shaft 111, an adjusting-screw 133, Fig. 1, is provided by means of which the shaft 116 can be rotationally adjusted relatively to the shaft 111. The flow of metal to the boot is controlled by a valve 72, Fig. 1, and an equalization of the temperature of the glass round the plunger 37 is secured by an island or dividing wall 80 in the boot.

Title: Improvements in and relating to mechanism for closing the open tubular end of the wrapper of a package
IPC: B65B19/02
Filed: 1941-02-20
Abstract: 550,066. Packeting. AMERICAN MACHINE & FOUNDRY CO: Feb. 20, 1941, No. 15135/42. Convention date, Feb. 20, 1940. Divided out of 550,042.[Class 94 (i)] Mechanism for closing the open end of a filled paper packet comprises a pair of members between which the packet. is positioned, and folders that rotate about axes coinciding with the ends of the member. The mechanism is especially suitable for use with a machine of the kind described in Specifioation 328,310, [Class 94 (i)], in which a wrapper is formed into a packet on an open ended hollow mandrel, one end of the packet is closed, and a batch of cigarettes is thrust through the mandrel into the packet which is stripped off the mandrel by the filling movement. The filled packet is received in a pocket formed by parallel plates 261, 262, Fig. 7, and by a pusher plate 225, Fig. 8, and a stationary guide plate 263, which together form the rear wall of the pocket. At the front of the pocket is a movable guiding and folding plate 264 which co-operates with the plate 263 to guide a packet from the mandrel into the pocket. The open end of the packet is closed by folders or tuckers 241, Fig. 7, which rotate about axes that coincide with the lines of folding 262a and thus ensure a sharp fold. These folders make the end folds and leave side flaps F, G, Fig. 8. The flap F is folded down by a reciprocating folder 239 which moves through an opening 273 in the guide 263. The flap G is folded by the movement of the package past the rounded edge 264b of the plate 264 as the package is moved by the pusher 225 into a delivery guideway or shoot 231, 232. Adhesive paste may be applied to the inner side of the flap G by a device composed of a number of nozzles 258 which also move through the opening 273. The nozzles 258 are normally closed by valves 290, Fig. 11, the ends of which project through the nozzles to enable the valves to be unseated. The nozzles may be formed in a casing 257 which is connected by a .pipe with a paste reservoir and as the valves are unseated by contact between the ends and the flaps of the packets, paste passes through the nozzles on to the inner faces of the flaps. The guide plate 264, Fig. 8, is formed with a groove 294 which prevents the valves of the paster from being operated, and paste ejected, if a package is not present. A lifting-plunger may be provided on to which the package is delivered before entering the guideways 231, 232. The plunger may be associated with a known form of detector which causes it to lift a defective package toward another guideway. Specification 550,042 is referred to.

Title: Improvements in Wrist-actuating Mechanism for Artificial Arms.
Inventor: DILWORTH OTTO LEGRAND
IPC: A61F2/58
Filed: 1918-02-25
Abstract: 124,149. Dilworth, O. Le G. Feb. 25, 1918. Limbs, artificial. - A wrist-turning mechanism for arm is arranged so that a movement of the opposite shoulder, or of the stump of the arm away from the body, unlocks the wrist, and a subsequent bending of the fore-arm first couples the wrist shaft to an actuator and subsequently rotates it to any desired extent, in which new position it may be locked by a repetition of the shoulder movement while the arm is still bent. The hand is mounted on a loose wrist-pin 37 which carries a spring-pivoted pawl 52 at its inner end. This pawl engages a ring of teeth on the casing to lock the pin in any angular position. The movement of the shoulder produces tension in a cord 46, which operates through pawl and ratchet gear to swing the pivoted forked lever 40 and move the collar 39 axially to disengage the pawl 52 and unlock the wrist. The mechanism is retained in the unlocked position,- after the movement of the shoulder is finished, by the shape of the teeth of the member engaging the lever 40. This member 41, Fig. 3, has deep spaces between the teeth into which the lever 40 fits when the wrist is locked, and shallow depressions 50 in the tops of the teeth which prevent the lever from returning to the locking position unless forcibly displaced by further actuation of the cord 46. After the wrist has been unlocked, the forearm is bent, which produces tension in a second cord 56 and rotates the collar 39. The collar moves round freely until a notch in its end registers with and is engaged by the pawl 52. Further bending of the arm and consequent rotation of the collar then rotates the hand through the medium of the pawl 52. When the head has reached any desired position, a further shoulder movement will release the lever 40 and allow the collar to slide back until the pawl re-engages the teeth on the casing to lock the hand in the new position. The hand may also be locked against bending movement about its pivot 66 by a pivoted lever 137 having a detent at its lower end that can be moved from one side into the path of teeth on the hand.

IPC: G04B21/10
Filed: 1932-05-30
Abstract: 388,972. Clocks. STOCKBURGER, S., St. Georgen, Schwarzwald, Germany. May 30, 1932, No. 15331. [Class 139.] Chimes.-Means for releasing and locking the chiming-mechanism of clocks consists of a lever 4 which is also adapted to move the chiming-barrel 16 axially so that a different set of chimes coacts with the hammers H. Lever 4 is pivoted at 3 to the front movement plate 1 and carries a wedge-shaped face cam 6 which moves a shaft 8 axially against its spring 12. This shaft is mounted in the front and rear movement plates 1, 2a and carries a member 15 which in turn moves axially the shaft 17 of the barrel 16 against a spring 18. Lever 4 has an arm 9 for locking the escape lever 10 of the chiming-mechanism. A spring bolt 13 on lever 4 moves in a slot 2 in plate 1 and a positioning pin 14 on lever 4 coacts with notches 11, 11a in the plate 1. With pin 14 in notch 11a the chiming-mechanism is locked by arm 9 against operation. With pin 14 in one or other of notches 11 the cam 6 moves the shaft 8 different amounts axially so that a different set of chimes is in use.

Title: Digital differential pulse code modulation
IPC: H03M7/32
Filed: 1971-05-18
Abstract: 1327667 Selective signalling COMMUNICATIONS SATELLITE CORP 18 May 1971 [20 May 1971] 15450/71 Heading G4H A first signal comprising successive digital code groups is converted into a second digital signal representative of the same information by generating a digital difference signal representative of the difference between a code group of the first signal and a stored reference digital signal, the stored reference digital signal being varied according to the difference signal. At a ttansmitter, the first signal is obtained by repeated sampling and digitizing of an analogue waveform (e.g. TV video), each n-bit code group resulting having subtracted from it the current value of the reference signal, the n-bit difference being reduced to n-2 bits in logic (by removing two high-order bits and if the difference signal was more positive than a positive threshold or more negative than a negative threshold replacing the n-2 bits by all ones or all zeroes respectively). The n-2 bits are multiplexed and transmitted, and are also (in the transmitter) expanded to n-bits by logic (which inserts the inverse of the highestorder bit twice between the highest-order bit and the next-to-highest-order bit) the result being added to the reference signal. At the receiver, the n-2 bits are demultiplexed then expanded to n-bits by logic similar to that in the transmitter and added to the previous contents of a register the sum being loaded into the register and converted back to analogue form. A second embodiment differs in providing a log or square-law compander, performing reduction from n-2 to n-4 bits, immediately after the transmitter logic which reduced from n-bits to n-2, bits and providing a non-linear to linear quantizer just prior to the other logic mentioned in the transmitter and in the receiver to increase the n-4 bits back to n-2, so the transmission uses n-4 bits.

Abstract: 827,137. Gun balancing gear. BOFORS A.B. May 14, 1958 [May 31, 1957], No. 15459/58. Class 92. A gun balancing gear has a spring 18 so connected to an elevatable mass 1-2 and to a mounting 4 that the spring force and the arm of its applied torque are continuously changed to balance the barrel 1 during movements in elevation and recoil; the spring being connected by slide means which are movable away from and towards trunnions 3 of the elevating mass 1-2 and which are guided by one arm of a bell-crank lever 5 mounted on a non- recoiling part 2 of the mass 1-2 and moved at its other end by a recoiling part of the mass 1-2. The lever 5 is pivoted at 6 on the breech casing 2 and has at one end a roller 7 between guides 9 on the gun 1 and at the other a roller 8 between guides 9 on the slideway 11. A line 14 passes over a pulley 15 to connect a follower 12 in the slide way 11 to the spring 18 in its casing 17 on the mounting 4. A tangent from the trunnions 3 to the wheel 15 makes a right-angle with the line of the slideway 11 when the gun is horizontal. Fig. 2 (not shown) illustrates an alternative using a rod 21 in place of the line 14 and pulley 15.

Abstract: 404,202. Shearing. SCHMIDT, W., 14, Burgstrasse, Erfurt, Germany. May 29, 1933, No. 15501. [Classes 83 (iii) and 83 (iv).] Reproducing.-In a machine for shearing the edge of a plate 2 clamped to a stationary table 1a, rotary cutters 13, 14 are mounted on a carriage moved to effect the cut. The cutters are mounted on shafts 45 driven by an electromotor, a slip clutch 48 on the lower shaft equalising the speeds of cutting disks of unequal diameter. The cutters are carried in a frame 16 adjustable about the cutting point by a rack 22 to vary the bevel angle of the cut. The end of the carriage is guided in rails 30, shaped according to the cut required, by rollers 10 on eccentric pins. By adjusting the pins the plane of the cutters is slewed relatively the line of the cut. In a modification a similar adjustment is made by mounting the bearings for the cutters shafts with slack in the direction of travel, Fig. 12, not shown. The upper blade shaft may be adjustable about trunnions and the bottom shaft may be adjusted in the vertical and horizontal directions.

Title: New and improved method of recovering olefin oxides from gaseous mixtures and hydrolyzing to form corresponding glycols
IPC: C07D301/32
Filed: 1938-05-25
Abstract: <PICT:0498119/IV/1> Glycols are produced by treating gases containing olefine oxides with a liquid absorbent which may contain a hydrating agent, heating to convert the oxide to glycol, and re-cycling the liquid to increase the concentration of the glycol.  The absorbent may be water containing a small quantity of sulphuric, hydrochloric, phosphoric or other mineral acid or other hydrating agent whether acid, alkaline or neutral, or water alone.  Preferably the heating of the liquid is effected under pressure.  The gases may be scrubbed in a tower 5 which may be packed, the gases entering at 7 in countercurrent to the liquid which is withdrawn at 10 and passed by a pump 11 (which produces the pressure employed in the heating) to a heat - exchanger 13 and a heater 14 for the hydration.  From the heater 14 the liquid passes through the heat-exchanger 13 back to the tower 5.  Alternatively the gases may be simply passed into the tower at a high temperature.  Glycol solution is withdrawn at 19 and fresh liquid is supplied at 21.

Filed: 1927-06-11
Abstract: 274,434. McCormick, F. July 16, 1926, [Convention date]. Void [Published under Sect, 91 of the Acts]. Type-printing telegraphs. - The telegraph described in Specification 262,805 is modified so that the colourchanging mechanism and also a caseshifting mechanism can be set for operation either by a special signal or by the printing of a period or other sentence-terminating character; in the latter case alternate sentences are printed in different colours or different cases of type. The mechanism described and shown is similar to that described and shown in Specification 262,805 with the following modifications. Case-shift mechanism. The typewheel 48, Fig. 4, has two rows of type and is axially slidable on the shaft 46, with which it rotates. The wheel is axially positioned by lever 96 under the control of the cam 89, which is rotated one step bythe ratchet 92 after each energization of the type-shift magnet 94. Circuits of type-shift, colour-shift and printing magnets. The type-shift magnet 94 is controlled by a commutator disc 100, Figs. 3 and 4. which rotates with the type wheel. When the type shift is to be controlled by means of a special signal the switch 102 is turned down, and when, therefore, the type-wheel is caused to stop in a position corresponding to the type-shift signal, a circuit is completed through the type-shift magnet 94, brush 133, contact 132, and armature 104 or 105, one or other of these armatures being closed as described in Specification 262,805. The circuit of the printing magnet 49 is interrupted, however, at 110 so that the tape feed is idle. When, on the other hand, alternate sentences are to be printed in different type, the switch 102 is turned up and the circuit of the type-shift magnet 94 is closed through brush 124 and contact 121, 122 or 123 whenever the type wheel stops in a position corresponding to a period or other sentence-terminating character. In this case the circuit of the printing-magnet 49 is closed through brush 110 and ring 109, and the tape-feed is actuated simultaneously with the release of the printing-hammer. The circuits of the colour-shift magnet 69 and its controlling disc 99 are similar to those of the type-shift magnet 94 and disc 100.
