Title: Web formation
IPC: D04H1/74
Filed: 1962-06-07
Abstract: 1,006,569. Web formation. ESTABLISSEMENTS REGINIER. June 7, 1962 [June 9, 1961; May 24,1962], No. 22085/62. Heading D1N. A web or sliver from a carding machine 9 is guided in an alternating to-and-fro motion parallel to the longitudinal axis of a receiving band 1, with the machine 9 being displaced normal to the to-andfro motion so that there is laid down on band 1 a strip of zig-zag superimposed formation. The carder 9 etc. and the lapping means are mounted on a carriage 3 which reciprocates along rails 6. The web, on leaving the doffer 12, passes up between conveyor belts 16,16a-which have tension adjusting means 21, 21a-on to a feeding belt 22 and between belts 25, and 25a which are oscillated to-and-fro by chain 37. As the carriage reciprocates and the belt 1 moves forward, a lap, Fig. 4 (not shown), of partly overlapping strips is formed with the fibres aligned almost parallel to the axis of the belt. At each edge of the lap there is a tapering "fall" which can be cut off and returned pneumatically to the carder, or preferably the apparatus is modified by the zig-zag strip being first laid down longitudinally on another conveyer belt 71, Fig. 6(not shown), which is situated transversely above band 1 and which feeds the strip on to belt 1 to form the lap. Rollers press the web on the belts 71 and 1 while further rollers strip the web from the belt 71. Chain 37 also drives through gearing which converts the oscillatory motion of the chain into unidirectional motion, all the rollers and belts of the lapping means-except belts 1 and 16,16a-so that the speed of the rollers and belts vary with the speed of the oscillatory motion of the lapping means.

IPC: A23G3/02
Filed: 1963-06-04
Abstract: 1,024,378. Measuring device. BENZ & HILGERS G.m.b.H. June 4, 1963 [June 9, 1962], No. 22136/63. Heading B5A. [Also in Division F1] A measuring and delivery device for plastic material such as butter comprises a rotating cylinder 4 having a duct 7 perpendicular to the axis of rotation which registers with filling and delivery openings 12 and 13 in a casing 3 surrounding the cylinder, the duct having a piston 8 therein reciprocated by the movement of a follower member connected to the piston over a stationary cam, independent means being provided for adjustably limiting the piston stroke. The follower member comprises a bar 17 connected to a control pin 16 engaging a guide pin 20 which is resiliently mounted in a slot 11 in the piston. The resilient mounting allows for the piston stroke to vary depending on the pressure of the plastic material above the piston whereby quantities of material of equal weight are delivered. In operation, when the duct registers with the openings material is drawn through the filling opening and material is ejected through the delivery opening as the piston moves down to the position in Fig. 2 (not shown) when the piston stroke is completed.

Title: Circular multi-feed hosiery knitting machine
IPC: D04B9/20
Filed: 1952-09-04
Abstract: 722,473. Knitting-machines. SCOTT & WILLIAMS, Inc. Sept. 4, 1952 [Sept. 8, 1951], No. 22259/52. Class 74 (2). To prevent fracture of yarns during reciprocatory knitting on a circular hosiery machine when two or more courses are knitted at each knitting stroke, the needles have thickened shank portions which are opposite the sinker nebs when the needles are raised to idling position, and the sinkers at the second or other non- leading feed are so actuated that the nebs of the sinkers are at no time allowed to clear the circle formed by the thickened shanks of the idling needles. The thickening of the necessary part of the needle shank may be replaced by providing a shank bent outwardly at that part. Varying size of stitches.-The second feed stitch cam can be adjusted so that the needles at the second feed draw stitches of different length in the rotary direction during reciprocatory knitting from those drawn during rotary knitting whereby " washboard " effects in the heel and toe are avoided. This cam may also be adjusted while making the welt so that every other course in the welt will be loose. The height of the stitch cam 360 at the trailing feed in the rotary direction is adjustable by cams 501-504 on the main pattern drum 120 which through a system of levers rock cams 1-4 which each have a single high point engageable with screws 19-22 in a lever connected to cam 360. Screws 19-22 enable the lengths of the stitches drawn to be adjusted independently for rotary and reciprocatory knitting. Specifications 12722/13, 102,711, [both in Class 74 (ii)], and 704,843 are referred to.

Title: Improvements in and relating to electric resistance welding apparatus
IPC: B23K11/26
Filed: 1951-09-24
Abstract: 703,110. Control systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 24, 1951 [Sept. 29, 1950], No. 22298/51. Class 38 (4) To ensure close co-ordination between the closure of the welding jaws and the initiation of the sequence of timing operations involved in resistance welding, the primary winding of the welding transformer is energized when the jaws are open, through an impedance and the voltage charge at the primary winding consequent upon closure of the jaws is utilized to initiate flow of welding current and triggering of the timing circuit controlling the welding time. In the system shown in Fig. 3, the welding transformer 2, 3 is supplied over normally non-conducting ignitrons 4, 5 shunted by a control resistor 55. A solenoid 11, controlled through normally non- conducting thyratrons 12, 13 operates the jawclosing-and-releasing gear. Sequencing and timing valves 18-22 are dependent upon a valve 63 controlled in accordance with the condition of the welding jaws. When these are open, a rectifier 57 (energized from both the primary of the welding transformer and a phase shift circuit 64, 65 associated with another transformer 59) maintains hold-off bias on valve 63, but upon closure of the jaws the reduction of voltage across the primary winding 3 allows transformer 59 to trigger the valve, which through transformer 54, 61 passes triggering impulse to initiate operation of the sequence and timing valves. To effect a weld, a switch 42 is closed; a tube 17, in consequence, conducts (subject to a possible delay by an "off ".timing circuit 44, 45) and a transformer 31, 35, 46, 47 in its anode circuit passes firing pulses to thyratrons 12, 13 previously held "off" by transformer 23-25. Solenoid 11 is consequently energized and the welding jaws closed. Tube 19, which was previously conducting, is now held " off " by transformer winding 31 and simultaneously tube 16 becomes conducting as a consequence of de-energization of a transformer 29, 37 and thus renders firing of the thyratrons independent of the condition of switch 42. Tubes 20, 21 are fired by transformer 54, 61 when the jaws close, tube 20 energizing relay 50 to complete the firing circuit of the ignitrons and so initiate flow of welding current, whilst tube 21 initiates discharge of the weld timing condenser 84, which is a source of " hold-off " bias voltage for tube 18. This tube eventually conducts and, through transformer 79, 88 cuts off tube 20 to terminate flow of welding current, whilst simultaneously initiating discharge of a " hold " timing condenser 87 controlling tube 22. This tube eventually conducts and, through transformer 38, 81, cuts off tube 16. De-energization of transformer winding 35 and consequent release of'the jaws and re-conduction by tube 19 follow, unless switch 42 is maintained closed, in which case timing condenser 45 imposes an " off " time. In a modified system, a separate high frequency current, controlled by the closure of the welding jaws, is employed to control the firing of tubes 20, 21.

Title: Automatic core loaders
IPC: B65H19/30
Filed: 1974-05-20
Abstract: 1468431 Automatic core loaders; shoots J P GERHART 20 May 1974 [6 June 1973] 22354/74 Headings B8R and B8S An automatic core loader for disposing a plurality of spaced cores 12, Fig. 2, on a mandrel 14, comprises a core box 18 provided with spaced semicircular grooves 26 for the cores 12 and movable longitudinally by a rack and pinion drive 152, 154, Fig. 6, past a discharge of a shoot 16, Fig. 1, whose other end is connected to a hopper 54. The cores 12 in the hopper are discharged into the shoot 16 by a rotary brush 14 and moved downwardly along the shoot by further rotary brushes 84, 86, 88, Fig. 1. At the beginning of core loading which is controlled by a rotary circuit (Fig. 9) an interposer pin 401 at the end of armature of a solenoid 402 is retracted and the cores are loaded into the box 18. At some time during its travel the mandrel 14 is caused to enter the core box and the cores are disposed about it. When the core box 18 has reached its end of travel by striking a stop 34 and disconnecting the drive 152, 154 a mandrel inflating head 202 is moved into one end of the mandrel 14 which is clamped by a pneumatically operable clamp. Following inflation and from clamping of the cores 12 on the mandrel the latter is lifted out of the core box 18 by a driven ejector arm 350, Fig. 13, and discharged on to a table 370. The mandrels 14 are supplied from a table, provided with an interposer 306, using the arm 350, which is carried by a support 336 and reciprocated between end position indicated by switches 700, 708 by an endless chain drive 300. The core loader is stopped if the cores 12 fail to be deposited in the grooves 26. This condition is detected by a switch 530 which stops a motor 24 of the drive 152, 154. Regular deposition of cores 12 in grooves 26 of the core box 18, causes advancement of the box 18 to its right-most position at which a reflected light control 32, Fig. 6, causes motor 24 to be de-energized to stop advancement of the box 18 which however continues under its momentum until a foot 33 engages a stop 34 on a pneumatic device 38.

Title: Improvements in or relating to separation of alcohols
IPC: C07C29/82
Filed: 1951-10-01
Abstract: <PICT:0695766/IV (b)/1> C2 and higher alcohols are separated from mixtures with other organic materials having boiling points in the same temperature range by treating the mixture with trimethyl borate to esterify the alcohols, separating a more volatile methyl alcohol-trimethyl borate fraction from the less volatile residual mixture, separating the more volatile organic material from the less volatile borate esters in the residual mixture, treating the alcohol borate esters with methanol to convert the esters to alcohols, and separating the more volatile methanol-trimethyl borate fraction from the less volatile alcohols.  The separation is particularly effective for alcohols in the C7 to C30 range especially for those prepared by the "Oxo" process.  In the Figure a mixture of C16-C20 "Oxo" alcohols with hydrocarbon is fed through 1 at a temperature of about 70-90 DEG C. into distillation tower 2 into which vaporous trimethyl borate enters through 3.  Methanol-trimethyl borate azeotrope passes through 4 to distillation tower 5 and the "Oxo" alcohol borate esters and the hydrocarbons are withdrawn through 6 to distillation tower 7.  A reduced pressure distillation takes place in tower 7, the hydrocarbons being taken overhead through 8 and the "Oxo" alcohol borate ester being withdrawn through 9 to distillation tower 10. Methanol vapour enters the distillation tower 10 through 11 and contacts the "Oxo" alcohol borate ester.  The methyl alcohol-trimethyl borate azeotrope is taken overhead to pressure distillation tower 5 which is operated at superatmospheric pressure. Under these conditions a fraction rich in methanol is taken overhead and may be recycled back to distillation tower 10.  The methyl borate withdrawn from 5 is recycled to distillation tower 2.  Separated "Oxo" alcohol product is withdrawn from the tower 10.  Excess methyl borate is used in the esterification reaction and an excess of alcohol is preferably used in the final methanolysis tower.  In the example a C12-C20 crude "Oxo" alcohol cut containing aliphatic hydrocarbons as impurities is treated with trimethyl borate and the alcohol borate esters are treated with methanol to give the free alcohols.

Filed: 1951-10-01
Abstract: 736,994. Conveyers. KING, D. M. Sept. 25, 1952 [Oct. 1, 1951], No. 22866/51. Class 78 (1). In a conveyer system of the kind wherein load carriers are supported and moved along by a moving endless belt, band, or chain on rollers attached to the belt or to the carrier so that relative movement between the belt and carrier is possible, a stop device is provided normally to prevent movement of load carriers beyond a predetermined point, together with means adapted, when the number of carriers held reaches a predetermined number, to effect removal of the stop device and to allow passage of one or more of the carriers. As shown in Fig. 1, the oncoming carriers 10 are held by a stop 21, each carrier on halting operating one of a series of switches 12-16. The stop 21 is withdrawn by the action of a solenoid controlled so as to operate only when a number of switches corresponding to the predetermined number of carriers to be held has been closed. The number of carriers which is then released is governed by the location of a secondary stop device 22, which is operative when stop 21 is inoperative and vice versa. Stops 21, 22 are mechanically linked, e.g. by means of a connecting bar in such a manner that the distance between them may be varied. The switch 11 is placed so as to restore stops 21, 22 to an operative and inoperative position respectively as soon as the required number of carriers have been allowed to pass the lowered stop 21. Loads may be suspended from the load carrier by means of a depending arm carrying a hook, the arm having a member adapted to abut against a stop in its operative position, and being movable according as to whether it is loaded or unloaded so that the abutting member is in a position to engage or not to engage with an operative stop. In another embodiment the depending arm 44, Fig. 13, has a member 42 adapted to co-operate with an operative stop, the member 42 being pivoted on the arm 44 and two loading hooks are provided, one 41 on the pivoted member 42 and the other 43 on the extremity of the arm 44. If work is loaded on the hook 43, the load carrier is subject to the system of stops provided, but if loaded on to the hook 41, the co-operating member 42 is pivoted out of the path of action of the stop system and the load carrier has then an unimpeded run. Specifications 701,610, 722,996 and 736,587 are referred to.
