Title: Improvements in the manufacture of artificial silk from viscose
IPC: D01F2/12
Filed: 1929-05-06
Abstract: 312,687. I. G. Farbenindustrie Akt.- Ges. May 31, 1928, [Convention date]. Cellulose xanthates.-Viscose silk having a matt silk-like lustre is prepared by emulsifying in the viscose one or more organic bases, other than aniline, which are more or less insoluble in water and are converted in the acid spinning bath into compounds more or less soluble in water, so that they are removed more or less completely from the spun threads. Suitable bases are, for example, quinoline, ethylaniline, dimethylaniline, or toluidine. Crude fractions may be used instead of the pure bases. The base or bases may be added at any suitable stage in the manufacture of the viscose, for example they may be added to the carbon bisulphide or the cellulose xanthate or to the viscose before it is spun. An emulsifying agent may be used and any suitable mixing device to obtain a uniform distribution of the added substance. The proportion of the organic base added may be varied within wide limits according to the degree of diminished lustre required, but must not be less than about 0.5 per cent of the viscose; for example, there may be added 1.5 per cent of quinoline or 1-2 per cent of commercial ethylaniline. Specification 2149/12 is referred to.

Title: Improvements in or relating to ticket machines
IPC: G07F17/42
Filed: 1959-04-24
Abstract: 889,392. Coin-freed ticket issuing machines. CAUSER, S. C. July 25, 1960 [April 24, 1959], No. 14080/59. Class 27. A coin-freed machine for issuing tickets for vehicle parking or the hire of deck chairs comprises a pawl 26 which is normally held disengaged from a ratchet disc 34 by a stop lever 29 but, on insertion of a coin, a lever 32 is moved to withdraw the lever 29, thus allowing the pawl and ratchet to engage and couple a customer-operated knob 12 to ticket printing and feeding mechanism. Tickets from a reel are fed above clockwork-operated time and data drums by a slipper 9 having horns 15 engaging holes in the ticket strip, the slipper being carried by a lever 16 which is moved backwards by a nose on a cam 18 rotated by the knob 12 and disc 34. As the lever 16 moves back, the horns 15 sliding over the ticket strip, a cam surface 37 on the disc 34 engages a member 38 on a lever 39 and lowers a hammer 8 so that the ticket is pressed against the time and date drums. At the end of the backward stroke, a spring 17 returns the lever and the horns 15 move the strip forward and push the ticket through a slot 13 to the customer. A spring- loaded guillotine has meanwhile been raised and held by a pivoted stop which is pushed back by the slipper 9 as it reaches its foremost position, thus releasing the guillotine and chopping off the ticket. The operation of the knob preferably also winds the clock or springs for operating bells or flags or operates a dynamo for charging batteries for lighting or other auxiliary devices. The tickets bear parking or other regulations which may be printed on the strip or impressed as the ticket is timed and dated and identification of the tickets may be facilitated by colour or coloured overprinting which may be varied from time to time. Each ticket may be gummed on the printed or the reverse side and may be gummed on issue or prior to loading; the gum may be covered by a tearoff strip. An inked ribbon may be used for inking the type face and may be moved progressively by the member 12. Coin slot closing.-A spring-loaded plate is moved over the coin slot each time the knob 12 is operated and when the ticket reel is exhausted a feeler causes a rod to slide and prevent the plate from being spring-returned to unblock the slot.

Abstract: 701,487. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 11, 1952 [June 14, 1951], No. 14714/52. Class 98(1) A support for an X-ray tube and an image intensifier combined with an optical instrument for viewing the image screen is characterized in that the X-ray tube and the image intensifier are rigidly mounted on a carrier rotatable about a horizontal axis disposed perpendicular to the principal ray and located at that end of the image intensifier which is remote from the X-ray tube and at a distance from the eyepiece of the image intensifier such that the displacement of the eyepiece of the optical instrument resulting from the rotation of the tube about the axis can be followed by the eye of the observer merely by slightly bending at most the upper part of his body. As shown, a chair 1 for the observer has a rotatable vertical support 3 on a base 4. A carrier 12 for an X-ray tube 14 and an image intensifier 13 is pivoted at 11 to the end of a column 10 fixed to the chair. Springs 26 connected between an arm 27 on carrier. 12 and an arm 28 on column 10 counterbalance the weight of the movable parts. The carrier is connected by a link 21 to a bar 22 which can be rocked about a pivot 25 on the base. by a pedal 24. The arrangement is such that the axis of pivot 11 passes through the eye of the observer seated in the chair. The observer can rock carrier 12 by pedal 24, and can also to some extent rotate the chair 1 and the parts supported thereby, so as to view the image of any part of a patient or object placed between the X-ray tube 14 and the image intensifier 13 through an eyepiece 20, which lies near the axis of pivot 11, so that for small movements of the tube 14 the observer need not move his head. For greater tube movements the axis of pivot 11 is arranged to pass through the pivot of the observer's head, so that movements of the head only are required. Still greater movements require also a slight bending of the upper part of the body.

Title: Means for making small linear measurements
IPC: G01R1/20
Filed: 1923-06-07
Abstract: 219,452. Shakespear, G. A. June 7, 1923. Variable resistances.-In a. device for making small linear measurements, an electrical conductor the resistance of which is susceptible to variations of temperature, is caused to be varied in form by a feeler in the gauge, and the required measurement is deduced from the variation of resistance following upon the altered rate of cooling. In one arrangement, the conductor takes the form of two spirals c connected in series and heated by a current led through insulated conductors g. The adjacent ends of the spirals are fixed to a rigid stem d, and the outer ends are secured to a feeler b, the sliding movement of which in the, block a is resisted by a light spring h. When the feeler is displaced in the gauging operation, one spiral c is contracted and the other is extended. By arranging the spirals as arms in a Wheatstone bridge, and connecting the terminal c to the galvanometer of the bridge, the variations in the resistance may be measured, and the movement of the feeler deduced. The cuter ends of the spirals may be fixed to insulators in the casing, and the adjacent ends attached to a member which is moved axially or transversely by the feeler. A single spiral or a deformable loop of wire may be used, or a pair of wires may be arranged close together so that the distance be tween them can be increased or diminished. The wires may be arranged in vacuo or surrounded by a liquid. Movement may be imparted to the feeler by the body being measured either directly or after mechanical magnification.

Abstract: 401,381. Making hollow-drill steels &c. BEDFORD, R. A., Grange Farm, Stumperlowe, Sheffield. May 26, 1932, No. 14996. [Classes 83 (ii) and 83 (iv).] Cased forms; destructible cores; working at specified temperatures.-Hollow drill steels or other hollow bars are made by providing a pre-formed hollow billet with a tubular lining of rustless or stainless steel or other metal or alloy as a close sliding fit in the bore of the billet, rolling, forging or otherwise reducing the compound blank on a core of a ductile metal or alloy having a coefficient of expansion higher than that of the blank and then removing the core, the lining remaining as a tight fit in the hollow bar but not welded, soldered or intimately allied thereto. The core may consist of copper or of a ductile copper alloy. A hollow blank may be formed by boring a solid billet or by casting a hollow billet and smoothing the wall by machining. The tube may be first inserted into the billet and the compound blank then heated to from 900‹ to 1100‹ C. A cold core, which may be coated with graphite or other lubricant, may be inserted while the billet is hot and reducing effected after it has attained the requisite reducing temperature, or the core may be inserted after the blank has cooled. The core may be inserted into the tube prior to its introduction into the billet. The ends of the blank may be sealed by welding, plugging &c. prior to reduction. The core may be removed by fracturing or cutting off the ends of the bar to expose the ends of the core which may then be drawn out. The core, prior to insertion into the blank may be weakened at intermediate portions by nicking &c. and filling up to preserve the contour, so that it may be withdrawn in separate lengths from opposite ends of the bar. According to the Provisional Specification the liner may be inserted into the blank as a fairly loose or close sliding fit.
