Title: Improvements in linking machine
Inventor: BURD SAMUEL IRVING
IPC: D05B7/00
Filed: 1959-05-19
Abstract: 917,530. Sewing-machines. PRESTIGE Inc. May 19, 1959, No. 16977/59. Class 112. The invention relates to a method of and a machine for automatically loading knitted fabrics on to the point dial of a linking machine. In one embodiment (see Figs. 1 and 4) the loading arrangement comprises a rotatable loading dial 30 driven from the linking-machine and including a ring 66 to which loading points are clamped, in radial grooves therein, by a ring 72 having a depending flange 73 which secures the dependent ends 74 of the loading-point shanks. A guard 76 is provided on the dial 30 to cover the driving rack 64. The loading points are spaced around the periphery of the dial in groups A, B, C, D &c., each group comprising a leading end set 32, a trailing end set 34 and intermediate, shorter, sets 36, 37, 38. The points of the end sets are long enough to extend over and into grooves in the points 14 on the linking- machine dial when these points are opposite each other. The distance from the leading- point of set 32 to the trailing point of set 34 is greater than the distance between the vertical edges of the fabric when that fabric is unstretched, so that the operator stretches the fabric to align the three or four end stitches of the leading margin with, and then impale them on, the points of set 32 of any group, and then align the end stitches of the trailing margin with, and impales them on, the points of set 34 of the same group. Intermediate portions of the fabric are then indiscriminately impaled upon the sets 36, 37, 38 of short points. As the loading dial rotates and points 32 approach the points 14 the fabric is transferred on to the latter by the oscillation of fingers 84 carried on the arm 86 of a lever oscillated by a link 92 connected with the needle cam 96 of the linking machine. The linking machine is provided with a brush 20, a work-trimming knife 18 and a guide 16. In a second embodiment (Fig. 8) each group of loading points is carried on a clip 114 which moves along a track 115 and is supported by pins extending upwards from a chain passing around sprockets 110 journalled below a bed-plate 100. The clips are propelled past the linking points by gears 116, 118 which engage racks 108 attached to the clips. The finger 84<1> transferring fabric from the loading points on the clips to the linking points 141 of the dial 121 is oscillated about its pivot-pin 158 by a link 921 and is reciprocated along the pin 158 by the action of a cam 164 on the extension 160 of the lever, a spring 166 effecting return motion. This arrangement may also be used in the embodiment of Fig. 1. A guide 144 is provided to prevent the ravel margins of the fabric interfering with the impalement of the fabric stitches on the linking machine points.

Title: Improvements in electro-magnetically operated timing mechanisms
IPC: H03B1/00
Filed: 1943-10-18
Abstract: 579,659. Electromagnetically - operated timing mechanism for bomb dropping &c. KELK, W. H. H., and BURNS, D. O. Oct. 18, 1943, No. 17047. [Class 38 (ii)] [Also in Group XXXVII] A train of electrical pulses of a frequency that is a sub-multiple of a fundamental frequency is obtained by feeding the " fundamental " pulses successively to the contacts of a rotary uniselector switch T<2> that is operated step by step in time with the pulses and connecting, say, every second or every fifth or every tenth contact of the switch T<2> to an outgoing line a by means of a preselector switch X. In the form shown, pulses at the fundamental frequency are generated by two cross-connected relays AP, BP the timing of which is varied by adjusting the resistance BPR in series with an extra winding of the relay BP. These relays are first set in operation by momentarily closing a switch FS. This energizes a relay FR closing a maintaining circuit at FR and also completes the circuit to the relays AP, BP which alternately energize and de-energize each other. Each time the relay coil AP<3> is energized contacts AP<2> and AP<3> are also closed. The latter causes the energization of the magnet TS4 which steps round the uniselector switch having two banks of contacts T\ T<2>. The contacts T<1> bring into play another positive terminal so that, even if a " stop " switch Y is opened the uniselector switch will continue to step round till the left hand contact T<1> is again on contact 1. The switch AP<2> conveys current to the second bank of contacts T<2> and every fiftieth or twenty-fifth or tenth or fifth or second contact of this bank is connected to the line a by moving the preselector switch X to an appropriate position. The switch X consists of two contact arms x<1> and a contact disc x<1> which move together and engage fixed contacts indicated by arrows. Thus a selected submultiple frequency is delivered to the line a which may energize a relay OR and operate a switch OR at this submultiple frequency. The arrangement may be used for dropping bombs at selected time intervals. Specification 478,391, [Group XXXVII], is referred to.

Title: Improvements in or relating to fuel supply means for reversible multi-cylinder internal combustion engines
IPC: F01L13/00
Filed: 1946-06-05
Abstract: 644,122. Reversing. KROON, B. C. June 5, 1946, No. 17094. Convention date, March 4, 1943. [Classes 7 (iii) and 7(v)] In a reversible multi-cylinder engine in which individual fuel pumps for each cylinder are driven by opposite faces of the same cams and the fuel is diverted to different cylinder injectors for the two directions of rotation, that part of the pipe line which is inoperative when going ahead is shut off. The Fig. shows the arrangements for a five-cylinder engine in which fuel pumps 91, 93 supply injectors 101, 103 during forward rotation through grooves 161, 163 in piston valves 171, 173. For reverse running, the valves are moved simultaneously to the right so that pump 91 supplies injector 103 through the groove 161, a pipe 181 and a groove 203, and pump 93 supplies the injector of the fifth cylinder through a pipe 183. Fuel is supplied from a tank 31 by a pump 33 provided with a pressure control valve 34 and a filter 36. During forward running, the pipes 181, 183 are in one arrangement, entirely cut off but, as shown, these pipes are used to convey fuel to cooling chambers in the injectors, the fuel flowing through a pipe 433, and a groove 203, the pipe 181, a groove 371 and a pipe 391, and returning by branches 401, 403 and a pipe 41 to the tank 31. Further small grooves may be provided in the valves whereby leaking fuel may escape and thus prevent pressure remaining after injection. Grooved rotary cock valves are described in detail as alternatives to the piston valves. The Specification as open to inspection under Sect. 91 comprises also the subjectmatter of Specification 644,198 which does not appear in the Specification as accepted.
Patent GB-716498-A (GB)
Title: Improvements in or relating to the fractional distillation of high boiling liquid mixtures
Inventor: JONES HOWELL HENRY
IPC: B01D3/38
Filed: 1952-07-18
Abstract: <PICT:0716498/III/1> In a process for the fractional distillation under reduced pressure of a mixture of high boiling liquids such as fatty acids, wherein superheated steam is passed through the fractionating column and/or a subsequent stripping column, saturated steam is generated by a heat exchange step with the vapours withdrawn from the top of the fractionating column, and this saturated steam is then superheated and used in the fractionating column and/or stripping column.  A mixture of cotton seed fatty acids at 50 DEG C., contained in tank 1, is introduced through conduit 2 into dehydrator 3, which is connected to foam - separator 4 and vacuum producer 5. The pressure at the head of the dehydrator is maintained at 3 mm. Super-heated steam is injected into the dehydrator through line 25. Fatty acids entrained in the steam leaving the dehydrator are separated in foam-separator 4. Dehydrated fatty acids, withdrawn from the dehydrator and separator by means of conduits 6a and 6b respectively, are heated to 250 DEG C. in preheating system 7.  The preheated acids are introduced, through one of the inlets 9a to 9f, into the side of fractionating column 10, which is heated at the base by reboiler 16 and is connected at the top to evaporative-condenser 11.  The cooling side of the condenser contains water, boiling under a pressure of 65 p.s.i.g.  The head of column 10 is maintained at a pressure of 3mm.  Part of the fatty acid condensate from condenser 11 is returned to the column as reflux, the remainder being withdrawn as product through conduit 13.  Part of the bottoms withdrawn from the base of column 10 is passed through conduit 18 to steam stripping column 19, which is maintained at 3 mm., and is surmounted by water-cooled, evaporative-condenser 21, The fatty acid overhead product from column 19 is collected in receiver 23; and non-distilled residue is withdrawn from the base of the column into receiver 33. Hot water is supplied to condensers 11 and 21 from tank 24 by means of conduit 26.  The steam evolved in the condensers is passed through lines 27a and 27b to superheaters 28 and 29.  The superheated steam from superheater 28 is injected through conduit 30 into reboiler 16, from whence it passes into column 10 through conduit 17, together with the circulating bottoms.  Steam from superheater 29 is injected through conduit 31 into the base of stripping column 19.  The steam which is injected into columns 10 and 19 passes together with vaporized fatty acids into condensers 11 and 21 repectively, but does not condense therein on account of the high temperature and low pressure; the steam is withdrawn from the condensers and is led to dehydrator 3 through line 25.  This steam carries with it a trace of fatty acid in the form of mist, which is subsequently removed in foam-separator 4.  The single fractionating column 10 may be replaced by a number of fractionating columns arranged in series. Specification 716,497 is referred to.
