Filed: 1943-11-01
Abstract: 802,650. Electrodes. VAUGHAN, F. H. M., GOLLOP, H., CRENNELL, J. T., and HILL, F. L. Nov. 1, 1944 [Nov. 1, 1943], No. 18070/43. Classes 37 and 53. Electrodes used in measuring differences of potential between points in a conducting fluid, e.g. sea-water, are made of silver impregnated with silver chloride and mounted within a protective casing of insulating material having apertures for entry of the fluid. Thus, a sheet of silver gauze A with a silver wire B welded along one of its shorter edges is rolled into the form of a cylinder with B as axis and impregnated with fused silver chloride. The electrode thus formed is mounted in an open-ended cylinder C of insulating material, e.g. that known under the Registered Trade Mark " Tufnol," provided with radial apertures D, and closed at the bottom by a disc E which has a hole in its centre to receive the protruding end of the wire B. The electrode is surrounded by glass wool I and a second disc F supports the other end of the wire B. A cable J is soldered to the wire B in the top half of the casing which is filled with pitch K and closed by a disc G. In a modification, the electrode is a composite member comprising a disc of silver with an upturned peripheral edge forming a shallow tray which if filled with a mixture of powdered silver and silver chloride, covered with a disc of silver gauze and the whole pressed together. The electrode is mounted in a circular tray-like member of insulating material and sealed as above.

Title: Improvements in or relating to circular knitting machines and the production of fabric thereon
IPC: D04B9/46
Filed: 1946-06-18
Abstract: 619,526. Knitting-machines. BROWN, L. June 18, 1946, No. 18217. [Class 74(ii)] In a machine in which the needle cylinder and loop measuring sinkers are movable vertically with respect to the stitch cam for varying the quality of the fabric, that portion of the stitch cam which engages a needle upon which a sinker loop is being measured is movable vertically with the needle cylinder. A constant relationship between the knitting yarn, the needles and the sinkers is thus maintained during the sinking of the loops. The invention is described in connection with a machine for knitting ladder resistant fabric as described in Specification 329,098, [Class 74(ii)]. The stitch cam is carried by a block 12 secured to the machine frame and is attached to a block 11 sliding within the block 12 and withdrawn from or advanced towards the needle cylinder by a lever mechanism connected by a rod 13 to the cam drum of the machine. A part 1 of the stitch cam is secured to a member 14 which slides vertically at one end 15 of the block 11. The part 1 has a horizontal surface 4 corresponding to the point at which the sinkers measure the loops around the needles. The member 14 is held against an adjustable stop 18 on a rod 17 by a spring 16 joining the rod 17 to the member 14. The rod 17 is secured to an arm 19 attached to the needle cylinder raising tube. Any adjustment of the cylinder raising tube causes corresponding movement of the cam part 1, the loops thus being measured always at substantially the same point in the length of the needles. Specification 422,779 also is referred to.

Abstract: 705,576. Valves. ELECTRAULIC PRESSES, Ltd. July 13, 1951 [July 24, 1950], No. 18369/50. Class 135 A valve controlling the admission and exhaust of pressure liquid to and from a hydraulic press comprises a valve body 1, Fig. 1, haying inlet, press and exhaust ports 8, 10, 14 respectively and housing independent spring-loaded non-return inlet and exhaust valves 3, 11 and a plunger control valve 15 operably connected to a handlever 40, Fig. 2. In the neutral position, Fig. 1, of the plunger 15 pressure liquid from a pump or accumulator passes through an inlet connection 24, body recesses 22, 21 and pipe 26 to the rear of a spring-loaded piston 5 to hold the inlet valve 3 closed. The exhaust valve 11 is held closed by its spring 13. To prevent surge in the exhaust main, the lever 40 is moved to, raise the plunger 15, whence radial ports 30 in the plunger are aligned with a body recess 23 to connect the press port 10 with the exhaust port 14 through a port 31, pipe 29, Fig. 2, recess 23, ports 30 and the plunger bore, prior to the opening of the exhaust valve 11 by the plunger. On movement of the lever 40 to lower the plunger from its neutral position radial ports 33 through the plunger are aligned with the recess 21 to connect the space behind the piston 5 to the exhaust port 14 and so permit the opening of the inlet valve 3 by inlet pressure. In a modification, surge in the exhaust main is prevented by employing a compound exhaust valve in lieu of the radial ports 30 and the plunger bore. In this arrangement, two exhaust valves 11, 35, Fig. 3, are arranged concentrically. the inner smaller valve 35 having a slightly longer stem so that it is opened first.

Abstract: 916,218. Sheet-delivery apparatus. PITNEYBOWES Ltd., and PARFETT, F. June 9, 1959 [June 9, 1958], No. 18389/58. Addition to 801,762. Class 100 (1). In a machine of the construction described in the parent Specification, means are provided for deriving a series of electrical pulses corresponding in number to the articles passing through the machine, these pulses being applied to an electronic counting unit which can be pre-set to transmit an output signal to electro-magnetic brake-actuating mechanism, on the receipt of any given number of pulses. The pulses are produced by a photo-electric cell 6 exposed to a light source 7 through successive slits round the periphery of a disc 1 driven in synchronism with the feed of the articles, and are applied to an electronic counting unit 8, pre-set by pushbuttons 10 on a control box, so that, on receipt of a predetermined number of impulses, an output pulse energizes a solenoid 11 to free a brake lever 14 from a latch 13. A spring then rotates the lever 14 counter-clockwise to apply the brake. A pulse from the unit 8 also illuminates a lamp 17, to distinguish between stoppage due to double-feeding and that due to the counting of a batch. Manual operation of a lever 24 clockwise acts on a microswitch 22 to extinguish the lamp, and also re-latches the lever 16. Specification 709,436 also is referred to.
Patent GB-596087-A (GB)
Title: Improvements in or relating to the manufacture of modified polyamides
IPC: C08G69/50
Filed: 1945-07-18
Abstract: In a process for producing N-alkoxymethyl polyamides by reacting together a high molecular weight synthetic linear polyamide, formaldehyde and an alcohol in presence of an oxygen-containing acid catalyst having an ionisation constant at least as great as 9.6 X 10-6 and an equivalent conductance measured at 25 DEG  C. in .01 N concentration no greater than 370 ohms-1 cm2, the polyamide, formaldehyde and alcohol are mixed and heated to reaction temperature before addition of the acid catalysts.  Suitable acid catalysts are phosphoric, p - toluenesulphonic, maleic, oxalic, acetic, formic, or hydroxyacetic.  The reaction may be performed at 50-200 DEG  C. and at pressures from atmospheric to 500 pounds per square inch.  It may be continued for 1 to 200 minutes after addition of the acid. Suitable alcohols are methanol, ethanol, propanol, isopropanol, butanol, olelyl alcohol, lacryl alcohol, benzyl alcohol, ethylene glycol, its methyl ether, methyl glycollate and allyl alcohol. Mixtures of alcohols may be used.  0.1 to 10 parts of formaldehyde are used per part of polyamide.  The molecular ratio of formaldehyde to alcohol is preferably between 1 and 1.5, but may vary from 0.1 to 2.0.  Paraformaldehyde, trioxane or formaldehyde-liberating substances such as methylal or hexamethylene-tetramine may be used. In an example, pulverized polyhexamethylene adipamide, paraformaldehyde, ethanol and water were mixed and heated to 120 DEG C.  A solution of phosphoric acid in ethanol was then forced into the mixture, the temperature was maintained for 20 minutes and the mixture extruded into aqueous ethanol containing ammonia to neutralize the catalyst.  The solution was filtered and poured into aqueous alkali to precipitate N-ethoxymethyl polyhexamethylene adipamide which had suffered relatively little degradation.  Other examples are given, using methanol or isobutanol in place of the ethanol.  The products may be used for wrapping, for coating fabric for leather substitutes, as adhesives as fibres, for moulding or as interlayers for safety glass.  Specifications 461,236 and 535,934 and U.S.A.  Specifications 2,071,250, 2,130,948, 2,321,890 and 2,321,891 are referred to.

Abstract: 757,302. Typewriters. LAMSON PARAGON, Ltd. Aug. 5, 1952 [Aug. 3, 1951], No. 18472/51. Class 100 (4). In an apparatus for feeding superposed record webs a relatively to interleaved carbon transfer webs b round the platen of a tabulator, typewriter or the like, two web feeding means are provided having feed pins 9 engageable with marginal apertures in the record webs, one feeding means 6 being mounted at the infeed side of the platen to push the webs in a straight line path to the platen, and the other, 5, mounted at the outfeed side to pull the webs away from the platen in a straight line path after they have been fed round the platen, both feeding means being simultaneously operated at the same speed and so positioned that the portion of the webs between the feed means is maintained in a relatively slack condition so that as they are fed round the platen they are sufficiently loosely disposed relatively to the platen and the transfer webs to permit their free feeding movement round the platen relatively to the transfer webs. The feed means may form an integral part of the machine, or may be supplied as a unit A to be detachably mounted on the machine. The webs a are normally fed large increments at each feed movement into imprinting position corresponding to a form length, but in order that the whole area of the transfer webs may be used the record webs are fed relatively to the transfer webs, thus the transfer webs, may remain stationary during several feed movements of webs a. The spaced pairs of endless tractors 5 and 6 are supported on rods extending between side plates 2, 3, and each tractor includes rotatable sprocket wheels 7 which drive endless chains 8 carrying the projecting feed pins 9. The tractors are driven from a gear 10, secured coaxially with platen 1 through gears 11, 12, 13 to pinions 15, 15a on shaft 14 extending transversely across the unit. Pinion 15 drives tractor 5, and pinion 15a through 16, 18, 19, 20 drives shaft 21 with the sprocket for tractor 6. The necessary slack is obtained by adjustment of one of the tractors, as by means of a coupling disc or sleeve keyed to shaft 14 and connected to pinion 15a by screws through slots 23, so that the pinion may be adjusted relatively to the shaft. Specifications 468,284 and 468,327 are referred to.

Abstract: 372,608. Insulators. THOMPSON, W. G., 6, Guildford Place, Newcastle-on-Tyne. June 29, 1931, No. 18715. [Class 36.] To prevent deposition of dirt on a multiunit insulator of the suspension or pedestal type, each unit is formed with upper and lower flanges connected by a waist portion, the flanges being so shaped that they respectively cooperate with flanges of adjacent units to provide an insulator in which the outer surfaces of the co-operating parts of adjacent units are substantially streamlined with respect to air currents flowing past these parts. The units are preferably formed so that the lower flange constitutes a rain shed. In the multiunit suspension insulator shown, in which each unit comprises a body A formed with an upper flange D, a bell-shaped rain shed B, and concentric internal petticoats C, C<1>, the units are connected together in such a way that the flanges D are disposed within the rain sheds B, as shown. The rain sheds B are formed with inwardly-turned rims B<1> which co-operate with curved lower faces D<2> on the flanges D to provide streamlined surfaces between adjacent units. Downwardly-inclined drainage channels D<1> may be provided in the upper faces of the flanges D. The units may be connected together by any suitable flexible or rigid means cemented or otherwise mounted on the ends of each unit. In the embodiment shown, the units are connected by caps E and pins F cemented in cavities A<1>, A<3> formed in the upper and lower faces respectively of each unit. A V-shaped annular ring A<2> may be arranged in the cavity A<1> to reduce the volume of cement required.

Abstract: 422,196. Coin-freed apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Automatic Musical Instrument Co. ; 1500, Union Avenue, Grand Rapids, Michigan, U.S.A.) July 3, 1933, No. 18783. [Class 27] Testing coins.-In coin-operated mechanism having means for conveying a coin from an insertion shoot to an operative position, a coin 6, Fig. 2, inserted through an opening 5 drops down a shoot 4 to a slot 7 in the flange 8 of a carrier disc 9 manually rotatable against the action of a return spring 63. Iron or steel discs are deflected away from the slot 7 by a magnet 53, and coins of too small a diameter fall through the slot. If a washer 6<2>, Fig. 6, with a central hole 58 is inserted, after a short rotation of the disc it becomes impaled on a pin 57 extending laterally from a spring lever arm 54 which initially bears against a cam portion 56, Fig. 7, on the disc, and is thus held away from engagement with a coin. In the case of a washer, continued rotation of the disc causes the rear edge of the slot 7 to force the washer, carried on the pin 57, upwardly out of the slot 7, the washer flexing a spring 60 in this movement, and the arm 54 pivoting against the action of a spring 62. The washer next engages an inclined groove 61 on the periphery of the disc which forces it off the pin 57 so that it drops down a shoot 64 to a return tray 66. Coin action, mechanical-connection.-A genuine coin is carried past a spring-pressed arm 20, which prevents its return, and rocks a lever 21 about a pivot 18. The lever 21 moves one side 23 of a bellows, expelling air through a valve 29, and the inclined end 30 of a spring 31 carried by the leaf 23 snaps over the lower end 32 of a spring switch arm 33 carrying an electric contact 44. The lever arm 21 is held in actuated position, after the coin drops from the disc 9, by its end 34 engaging ratchet teeth 35 on the end of an arm 36 pivoted at 37 and connected to the arm 21 by a spring 22. At the end of the movement of the disc 9, a projection 38 thereon engages a projection 39 on the arm 36 to depress this and allow the arm 21 to return to its initial position. The leaf 23 of the bellows opens slowly by the admission of air through a valve 51 and the hooked end 30 of the spring 31 by its shoulder 43 causes the contact 44 to engage a contact 45 on a spring arm 46. As the leaf 23 opens the arms 33, 46 flex and the contacts are maintained closed until the end 30 snaps off the end 32 whereupon the switch opens. The retarded opening of the switch allows time for a solenoid or like instrument in the electric circuit controlled by the switch to complete its operation.
