Title: Mechanism for activating timing devices
IPC: G04F3/02
Filed: 1963-08-23
Abstract: 1,016,458. Retractive switches; retarding action of switches. ELASTIC STOP NUT CORPORATION OF AMERICA. Aug. 23, 1963 [Sept. 13, 1962], No. 33553/63. Heading H2B. A time-delay switch is provided with an operating mechanism which prevents interference with the operation of the switch, once initiated, until the preset delay interval has expired. The actuating member 16 of the switch unit (Fig. 1, not shown), when moved to the left initiates a timed interval during which it progressively returns to the position shown. When plunger 22 is pushed it engages and rotates a lever 34 pivoted on shaft 41 between two discs 40 (only one shown) which are mechanically connected together and also pivoted on shaft 41. Lever 34 is rotated against the action of a " rat-trap" spring 74 and tensions another " rat-trap spring 64 anchored on a drive-pin 52 secured between discs 40. Due to a latch-bar 86 engaging notches 107, discs 40 cannot rotate until surface 108 on lever 34 cams the latch 86 out of engagement, whereupon discs 40 quickly rotate and a cam 50 thereon urges follower 116 to the left in passing to the operated position (Fig. 13, not shown). Follower 116 is integral with collar member 30 which thus moves rod 16 to operate the switch unit (not shown) and initiate delayed retraction. The movement of shoulder 114 on member 30 allows a blade spring 104 to lift a latch 94 behind the face 79 of lever 34, thereby maintaining lever 34 and discs 40 in the operated position (Fig. 13, not shown) against the restoring force of spring 74. In this condition movement of plunger 22 is ineffective and can have no effect on the preset time delay. When member 30 is returned to its Fig. 6 position the shoulder 114 pivots latch 94 out of engagement with lever 34 which springs back, taking discs 40 with it by virtue of a pin 78 thereon. The cam 50 has no effect during this return rotation since it pivots - on pin 52 against a light spring 54, which then returns it to abut a pin 58 in readiness to initiate a new timing cycle.

Title: Improvements in or relating to the finishing of cellulosic textile materials
IPC: D06M10/10
Filed: 1961-09-20
Abstract: Yarns, fibres, threads, woven and knitted fabrics and goods made wholly or partly from natural or regenerated cellulose are treated with an aldehyde or a substance which can condense with itself to form a resinous condensate or with a mixture of two or more substances which may intercondense to form a resinous condensate to modify their properties and then irradiated with electromagnetic radiation, e.g. gamma rays and X rays, able to penetrate the textile material or accelerated electron irradiation able to penetrate the textile material and having a particle energy less than 1MeV at low dosage such that cross-linking between the carbon atoms of the cellulose molecules of the textile material is effected without causing substantial degradation of the cellulose molecules with a resultant substantial loss of fibre strength to improve the mechanical properties of the textile materials.  Radiation dosages of less than 107 rad and of at least 103 rad are used, suitable sources of gamma rays being Co60 and CS137 and suitable sources of accelerated electrons being cascade, Van de Graff and linear accelerators and radio-active sources, e.g. Sr90.  Suitable aldehydes and condensable substances are formaldehyde, adipic aldehyde, glyoxal, amino-aldehyde, resin precondenates, e.g. precondensates of formaldehyde with urea, thiourea, ethylene urea or homologues thereof, urone, acetylene-diureine or derivatives thereof, dicyandiamide or melamine, resin precondensates of formaldehyde with phenol or phenol derivatives, ketone-aldehyde resin precondensates, aziridinyl compounds, triazone derivatives and diglycide ethers. The textile material may be treated with the aldehyde in the swelled condition in the presence of an acid reacting substance, rinsed with water and then irradiated wet or dry or it may be treated with an aqueous solution of the aldehyde in the presence of a catalyst, dried and heated to a temperature above 100 DEG C. for a short time.  The textile materials may be treated with an aqueous solution or dispersion of the condensable substances, squeezed out, heated for a short time to a temperature above 100 DEG C., washed and then irradiated wet or dry.  The textile material may be treated with a solution or dispersion containing 1-5% by weight of a sensitizer, e.g. 1,4 diphenyl benzene, prior to irradiation.  During the process embossing effects, e.g. goffering, ripple, schreiner or moire effects, or calender effects with or without friction, may be imparted to fabrics.  Fine fabrics made from relatively high twisted yarns, e.g. voiles and marquisettes, may be treated.  The treated textile materials possess good crease resistance and dimensional stability, increased abrasion and tear resistance and a pleasant soft hand. Specifications 906,324, 917,151 and 917,437 are referred to.

Title: Improvements in or relating to vehicle wheels
IPC: B60B15/18
Filed: 1929-11-06
Abstract: 338,350. Athey, I. H. Nov. 6, 1929. Endless-track vehicles.-A portable track or vehicle wheel comprises a rigid inner load supporting wheel suspended within a flexible outer tread band having suspension members which co-operatively connect the load supporting wheel at points adjacent its periphery to the tread band. In the construction shown in Figs. 3 and 4, for drawn vehicles, the rigid inner wheel 35 is suspended by means of arms 38 from the upper portion of the flexible endless track 36, the arms being preferably formed integral with tread shoes 37 and carrying pins 39 which co-operate with inwardly-turned flanges 40 of the wheel 35. The shoes 37 are pivoted together as shown. Rubber or metal spring buffers 42 absorb shocks and limit the extent to which the arms can close together. The arrangement is such that the suspension pins 39 when symmetrically disposed would lie on a circle of smaller diameter than the flanges 40, so that when the wheel 35 is under load the parts take up the position shown in Fig. 3 with the wheel clear of the lower portion of the track but suspended from the upper portion. The inner ends of the suspension arms are connected together by a flexible band 43 so as to limit the separation of the inner ends of the arms. In a modification the band 43 is dispensed with. In the construction shown in Figs. 7 and 8, for either drawn or propelled vehicles, the rigid inner wheel 45 has inwardly-turned flanges 49 having notches 50 formed therein. Each shoe 47 of the track has an inwardlyprojecting suspension arm 47<1> provided with a buffer 52 and a hinge pin 54 for links 53. The links 53 of adjacent shoes are connected together by pins' 55 which extend beyond the links so as to lie within the peripheries of the notched flanges 49. The pins 55 seat themselves in the notches of the upper part of the wheel so as to take the load and also to limit relative rotation between the wheel and the track, thus transmitting the drive from the wheel to the track. In the example shown there are 26 shoes in the track and 53 notches in the wheel 45. Modifications are described in which (1) the inner ends of the suspension arms are connected by links to the periphery of the rigid inner wheel, (2) the inner ends are connected by slotted links to an endless chain of links the pivot pins of which engage in notches in the flanges of the rigid wheel, and (3) the track comprises a continuous spring band with a corrugated tread surface of rubber or other material, this band having suspension links pivoted thereto, the rigid inner wheel being a disc with radial slots for the inner ends of the links.

Title: Improvements in devices for measuring the speed of vehicles
IPC: G01P3/36
Filed: 1928-11-19
Abstract: 300,914. Waltman, J. M., and Sirks, J. F. Nov. 18, 1927, [Convention date]. Addition to 264,487. Telescope systems.-The invention described in the parent Specification is modified for use on a monocular telescope by mounting several prisms on a changing device whereby they may be brought in succession before the objective, and simultaneously actuating a stop watch. The angles of the prisms are selected so that the displacement of the two images by a definite amount, e.g. the width of the track, corresponds to a known distance of the .car from the observer for each prism and thus the speed of the car can be determined by means of the time between which coincidences take place in using successive prisms. The rotatable disc h carrying prisms f' - - f<4> is mounted on the objective cell of a monocular field glass by means of a clamping ring b. Spring catches are provided to ensure correct register of each prism in front of the objective. A stop watch r is carried in a casing q hinged to the lever p. The casing is shown in position for use, but may be folded for packing. For night use the distance between headlights is the basis of determination and involves the use of a different set of prisms. In a modification the watch is fixed to the casing and the prisms are changed by a projecting lever.

Abstract: 427,203. Weighing-apparatus. AVERY, Ltd., W. & T., and JACKSON, A. N., Soho Foundry, Birmingham. Dec. 4, 1933, No. 33972. [Class 143] Weighing-apparatus for the weighing of animals such as pigs comprises a cage 4 or weighing platform, a suspended automatic dial weighing mechanism 8, means for suspending the cage or weighing platform from the weighing mechanism, means for hoisting the cage or weighing platform from the ground when it is desired to carry out a weighing operation and a chart for the dial divided into zones z denoting the grade of the animal and bearing indications giving the corresponding carcass class and also the required length of feeding period to be given to an animal to fatten it to a carcass class. The platform may be raised by a hand lever 6 carrying the cage on its short arm and retained during weighing by a hook 5<a>. The hoisting lever may be situated between the weighing mechanism and the supporting frame 9. In a modification, instead of a hoisting lever, an eccentric pulley rotated by a crank handle may be used to lift the cage by means of a chain, the extent of rotation of the pulley being limited by a projecting tooth.
Patent GB-741712-A (GB)
Title: Improvements in or relating to the preparation of citrazinic acid and its amide
IPC: C07D213/81
Filed: 1953-12-07
Abstract: Citrazinic acid amide or citrazinic acid is prepared by a process which comprises heating a citric acid amide and/or a citric acid ester amide in one or more high boiling solvents and in presence of one or more basic reaction promoters at a temperature above 80 DEG C. (preferably 100-180 DEG  C.), whereafter, if desired, the citrazinic acid amide formed is hydrolysed to citrazinic acid.  The heating step is preferably conducted under substantially anhydrous conditions and subsequent hydrolysis of the amide may be effected by adding aqueous alkali to the reaction mixture when formation of the amide is substantially complete. Alternatively, water is added to a completed reaction mixture in which excess alkali is already present and the amide is saponified by heating.  Starting materials are preferably citric acid triamide or the reaction mixture obtained by the amidation of citric acid esters.  The solvent is preferably one or more high boiling mono- or polyhydric alcohols or functional derivatives thereof (e.g. ethylene, diethylene and propylene glycol, 1:2:4 - butanetriol, butanol, glycerol and butoxyethylene glycol); mono- or polyhydric phenols (e.g. phenol and resorcinol) or acid amides (e.g. acetamide and urea).  The basic reaction promoter may be one or more alkali metal hydroxides, alkali metal salts of weak acids (e.g. carbonates, bicarbonates or phosphates), alkali metal alcoholates or phenolates, alkaline earth metal oxides or hydroxides, or a volatile substance (e.g. amines and ammonia).

Patent GB-342771-A (GB)
Title: Improvements in the production of acetylene
IPC: C07C5/35
Filed: 1929-11-08
Abstract: Acetylene is produced by heating gaseous or vaporized hydrocarbons with a large excess of steam to a temperature exceeding 1000 DEG  C. for a short time; the treatment of methane alone or gases containing no other hydrocarbon is excluded. Preferably, the duration of heating does not exceed 2 seconds, and 5-20 volumes of steam are taken for each volume of hydrocarbon. According to the examples, (1) oil gas containing hydrogen 20, methane and ethane 36, and ethylene and propylene 44 per cent is mixed with 10 times its volume of steam and passed rapidly through an unpacked silica tube heated to 1250 DEG C., the outgoing gases being rapidly cooled; (2) a gas containing ethane 92 and methane 8 per cent is treated similarly, a product containing almost equal amounts of acetylene and ethylene being obtained; (3) the same gas as in example 1 is mixed with 20 times its volume of steam and passed rapidly through a retort packed with fireclay and heated to 1300 DEG  C.  The acetylene may be recovered from the gases by washing with solvents, in which connection Specifications 331,610 and 331,654, [both in Class 2 (i), Acetylene], are referred to; alternatively, the products may be used directly for the manufacture of acetaldehyde, as described in Specification 302,515, [Class 2 (iii), Dyes &c.].  Reference has been directed by the Comptroller to Specification 334,178, [Class 2 (i), Acetylene].

Patent GB-389922-A (GB)
Title: Circuit arrangement for manually operated telegraph exchange systems
IPC: H04L12/04
Filed: 1931-12-10
Abstract: 389,922. Telegraph-exchange systems. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 10, 1931, No. 34273. Convention date, Dec. 24, 1930. [Class 40 (iii).] In a manual telegraph-exchange system, a device is provided at the exchange for the production of a signal of a nature different from the calling or clearing signals and a subscriber or other exchange operator can bring the device into operation by an impulse transmission of a predetermined character. In establishing a connection, an answering plug ASt is inserted into the jack AK energizing the line relay C which at contact cII operates slowrelease relays X1, X2 in parallel. On extending the connection by inserting the calling plug VSt into the jack VK, test-relay P operates, if the required subscriber is free, and at p1 opens the circuit of windings I of relays X1, X2 which remain operated over their second windings since slow-release relays Y1, Y2 are arranged to operate before the contacts x1I, x2I fall off. The special signal at the exchange is produced by an impulse transmission constituted by the double actuation of the key which is normally operated to produce the clearing signal. When the key e1 is moved to its opposite contact, the relay Y1 is shortcircuited and opens the circuit of winding II of relay X1 which, at contact x1II prepares a circuit for the terminal signal lamp SL1 and at contact x1III prepares a circuit for a relay F1. When the contact e1 is returned to its left-hand position, relay Y1 again operates, and at contacts y1II, ylIII completes the prepared circuits for the lamp SL1 and for the relay F1. On the second actuation of the key contact e1, Y1 is de-energized, and closes through contacts y1I, f1I the circuit of winding II of relay X1. The operated contacts x1II, f1II close the circuit of a slowacting interrupter LV through the lamp SL1 to produce a signal constituted by a flickering light. The signal persists until the exchange operator answers the signalling subscriber and opens the circuit of the relay F1 by operating a key ML. When the normal clearing signal is transmitted, X1, Y1 fall off as described but the relay Y1 reoperates to close an uninterrupted circuit through the lamp SL1. The circuit of the flicker relay F1 which is energized on the transmission of the clearing signal is opened at contacts pI, pIII when the connection is broken down. At the exchange the special signal constituted by the flickering light may be replaced by an optical signal, such as a falling flap indicator, and supplemented by an acoustic signal.
