Title: Improvements in carding machines for textile fibres
Inventor: CLARK ERNEST
IPC: D01G15/80
Filed: 1950-11-30
Abstract: 684,370. Carding-engines. ABINGTON TEXTILE MACHINERY WORKS. Nov. 30, 1950, No. 29369/50. Class 120(i) In the operation of apparatus for stripping the main cylinder 3 and doffer 4 of a carding machine, stripping nozzles 19 and 22, connected to a suction box 18 carried on a carriage 17 slidably mounted on a traverse tube 8, are moved across the cylinders by the engagement of a pawl 30 with a traverse screw 29 which is continuously rotated by the doffer cylinder through a gear 15 and intermediate gearing (not shown). When the carriage nears the terminus of its movement a bevelled end portion 41x of a trip 41 passes beneath a flange 39 to raise a spring-constrained pin 36 out of engagement with an annular groove 35 and with the carriage thus held frictionally the screw 29 is forced to the right (as viewed in Fig. 4) so that the crowned end 60 of the screw swings a pivoted arm 59 of a rock shaft 57 which is thereby rotated to cause an arm 63 to raise a latch 54 out of engagement with a notch 53 on a disc 52 which is integral with an eccentric bearing 48 rotation of which is then caused by the descent of a counterweight 56 to move a pinion 50 into engagement with a gear 51 on the doffer shaft to rotate a countershaft 49 thereby resuming the lap-feeding operation: the longitudinal movement of the screw 29 is arrested by the engagement of a shoulder 47 with a fixed stop 45 whereupon the traverse movement of the carriage 17 is resumed until a shoulder on the trip 41 abuts a bracket 37 simultaneously with the freeing of the pawl 30 from the thread 29 by engagement of its arcuate arm 33 with a lever 34. When a further stripping is required the operator holds the pawl 30 disengaged from the thread 29 and slides the carriage 17 to the initial position: such movement releases the pin 36 which springs into the groove 35 if the screw 29 has been returned to the locking position by the weight of the arms 59 and 63 or otherwise it engages a subsidiary thread 42 and thereby the screw 29 is automatically returned to the locked position : the weight 63 is manually lifted to rock the latch 54, thus interrupting the lap-feed operation, before the pawl is engaged with the thread 29. Suction, applied to the nozzle 19, 20, via a flexible pipe 23 and conduits 24, 25, is controlled, as required to effect complete stripping, by a manually operated valve 27.

Title: Improvements in or relating to filling valves and the like
IPC: F16K1/38
Filed: 1952-11-21
Abstract: 728,169. Valves. RALSTON, J.D. Nov. 21, 1952, No. 29480/52. Class 135. A liquid-filling valve comprises a tapered closure member movable into sealing engagement with a resiliently walled member forming part of the flow passage under the influence of a force of sufficient strength to distort the resilient wall and then allow of its recovery so that the liquid in a small bore discharge tube is retracted into the tube on the closure of the valve. As shown in Fig. 1, a cylindrical casing 17, of non-magnetic material having an inlet 22 and a small bore discharge tube T houses a valve closure member C having a tapered end 10. The valve C which is of magnetic material is raised on the energization of an electromagnet E and on de-energization of the magnet falls under its own weight to distort the walls of a rubber seat member S which afterwards recover their initial shape to create a suction and so retract liquid into the tube T to prevent drip therefrom and ensure the dispensing of an accurate amount of liquid. In a modification, an electromagnet 30<SP>1</SP>, Fig. 4, independent of the electromagnet E surrounds the casing 17 and on energization closes the valve.. In this case, the liquid supply to the valve passes through a tubular member 38 which also secures the casing 17 to the magnet E, the liquid flowing through flutes 35. In another arrangement, the member S, Fig. 5, may be disposed in the drain outlet of a container and the valve member C1 guided vertically above it by a rod 43 which passes through the top of the container and is operated manually by a handle 45. To permit flow of liquid past the valve, the flutes in the parallel portion of the valve member may be of any shape or number, the parallel portion may be square or hexagonal or holes may be drilled therethrough. The seat member S may have grooves 68, Fig. 18, or be made from metal and shaped as in Figs. 19 or 20. The valve casing may be of glass, nickel-plated steel or other metallic or non-metallic materials which are readily cleaned and do not tarnish or react with the liquid which is being controlled.

Patent GB-411744-A (GB)
Title: Improvements in and relating to varnish compositions
Filed: 1933-10-25
Abstract: In varnishes consisting of a combination of an oil with a synthetic resin of the phenol-aldehyde or the polyhydric alcohol-polybasic acid type, the oil, which may be of vegetable, fish or animal origin, is treated with a metallic oxide or hydroxide to form a soap insoluble in the oil, a solvent for the soap, e.g. rosin or a fatty acid, being then added and the whole heated prior to combination with the resin which is rendered soluble by preparation in the presence of rosin or a fatty acid. Prior to uniting the oil and the resin, driers and glycerine may be added to the oil.  In a modification, the rosin treatment of the oil is omitted, the soap being brought into solution by the rosin in the synthetic resin.  Alternatively the oil is heated to produce a more viscous oil and a phenol and an aldehyde are added. In one of a number of examples, hydrated lime is added to tung oil and the mixture heated to 350 DEG  F., insoluble calcium soaps being formed.  Rosin is added and the temperature raised to 400 DEG  F. after which the mixture is cooled to 350 DEG  F., glycerine is added and the whole heated to 475 DEG  F.  Equal weights of the oil so treated and an oil soluble phenol-aldehyde resin are heated together at 400 to 450 DEG  F. and after cooling are thinned with an equal weight of solvent.

Title: Preparation of phthalic acids by oxidation
IPC: C07C51/265
Filed: 1959-09-01
Abstract: <PICT:0864106/IV (b)/1> An oxidation process for the production of phthalic acids and esters comprises continuously introducing a xylene and a lower alkyl toluate into the first of a series of oxidation zones, continuously oxidising said xylene and said alkyl toluate in said zone in the liquid phase by passing an oxygen-containing gas p therethrough, continuously withdrawing oxidate containing unreacted alkyl toluate from said first zone, passing said withdrawn oxidate to a second oxidation zone while simultaneously introducing additional xylene to said second zone, continuing the oxidation of said withdrawn oxidate in the presence of said additional xylene in said second oxidation zone in the liquid phase by passing an oxygen-containing gas therethrough and continuously withdrawing oxidate containing a monoalkyl phthalate and a phthalic acid from said second oxidation zone, the amount of xylene introduced into each oxidation zone being proportioned to provide approximately equal rates of oxidation in each zone, in terms of acid number increase per hour, and the total amount of xylene introduced being in excess of that stoichiometrically equivalent to the amount of lower alkyl toluate introduced in the process.  The terms "phthalic acid," "toluic acid" and "xylene" are intended to include all the various isomers and the term "lower alkyl" is defined as containing 1 to 4 carbon atoms. The oxidation may be carried out at 120-230 DEG C. and at elevated pressure in the presence of an oxidation catalyst e.g. cobalt toluate using air as the oxidising gas.  In a preferred embodiment illustrated in Fig. 2 alkyl toluate is introduced into oxidiser No. 1 through A, residue from previous oxidations e.g. partially oxidised xylenes and toluates, is introduced through B, catalyst is introduced through C and the off gases from oxidiser No. 2 containing both oxygen and xylene are introduced through E.  The oxidate is withdrawn from oxidiser No. 1 and passed to oxidiser No. 2 through D and additional xylene simultaneously introduced through F. The oxidate is withdrawn through G, unreacted xylene removed in the xylene stripper and the stripped oxidate esterified and then distilled to give an alkyl toluate which is recycled, a dialkyl phthalate and a high boiling residue.  In examples p-xylene and methyl p-toluate are oxidised and the stripped oxidate esterified with methanol.  Specification 809,730 is referred to.

Title: Broadband waveguide circulators
IPC: H01P1/39
Filed: 1972-06-27
Abstract: 1356884 Waveguide junction circulation WESTERN ELECTRIC CO Inc 27 June 1972 [29 June 1971] 30044/72 Addition to 1305006 Heading H1W The bandwidth of an H -plane waveguide junction-circulator is improved by providing two gyromagnetic elements of different (resonant) lengths. The invention is an improvement on that described in Specification 1,305,006 according to which an element (or elements) extends along the axis of symmetry of the junction and is proportioned such that the reflection coefficients for the two counter-rotating resonant modes and that of the in-phase mode are spaced by 120 degrees over a wide band. As shown in Fig. 4, two such elements 52, 54 of unequal size are separated by a dielectric gap and form quarter-wave resonant sections for the counter-rotating modes at two spaced frequencies whereby the operating bandwidth of the circulator is extended. In addition, the resonant frequencies of the in-phase modes of the two elements are determined by quarterwavelength conductive pins 44, 53 whereby further extension of the bandwidth is obtained. In a modification of this construction (Fig. 8, not shown) one of the gyromagnetic elements rests on a conductive disc which behaves as an impedance transformer and smooths the phase/ frequency characteristic determined by the various resonances. The operation of the construction of Fig. 5 is similar to that of Fig. 4 but, in this case, the two elements 55, 56 extend from a central conductive septum and are spaced from the walls 40, 41 of the junction by dielectric discs 58, 59. In the construction of Fig. 6, the elements 71, 72 are resonant in a halfwave mode and are terminated at both ends by dielectric spacers 73, 74, 75. In the construction of Fig. 7, the elements 84, 85 extend into cavities 82, 83 whose depths determine the resonant frequencies of the in-phase modes of the two elements. The resonant frequencies of the counter-rotating modes are determined by the total lengths of the elements.
