Title: Coating sheet material
Filed: 1939-12-08
Abstract: 537,919. Coating webs. DYKES, W. U. (Warren Co., S.D.). Dec. 8, 1939, No. 31795. [Class 140] In coating flexible webs of fabric, felt, paper, rubber, resinous material, regenerated cellulose or cellulose esters or ethers, the coating composition is smoothed by a rigid surface towards which the web is urged by means of an air jet. As shown in Fig. 1 a web 1 passes over guide and tensioning rolls 3, 3, and is coated on side A by roll 4, the coating being smoothed by air jet 11. This coating may be omitted. A roll 7 acts as a backing roll and supports the web during this smoothing. Coating composition is applied also to roll 7 from roll 8 and is smoothed by a second air jet 10, or alternatively, by a scraper or another roll. Roll 7 rotates in a direction opposite to that of travel of web 1 or in the same direction at a peripheral speed different from the linear speed of the web and so coats and smooths side B of the web. The double coated web is then dried in a drier 12. In the modification shown in Fig: 2 the web 1 is coated on side A by a roll 16 and on side B by a pipe 19 co-operating with a roll 18 and the coatings are smoothed by an air jet 20 co-operating with a rigid scraper 21.

Abstract: 1392706 Ticket systems NATIONAL RESEARCH DEVELOPMENT CORP 9 Oct 1972 [8 July 1971] 32052/71 Heading G4T In a ticket system, e.g. a public transport system or, as described, a car-parking system, a user of the system purchases a magazine 10 containing a coil of strip ticket material proportional in length to the purchase price, when beginning his use of the system the user plugs his magazine into a first apparatus, Fig. 3 (not shown), which marks the strip at a position spaced from its free end by a distance representative of the beginning of such user, and on finishing his use of the system the use plugs his magazine into a second apparatus, Fig. 4, which senses the marks representative of the beginning of the use and severs from the strip a length representative of such use. The first apparatus (Fig. 3), includes a latch 22 (as in Fig. 4), for holding the plugged in magazine, rolls 19 for withdrawing the strip from the magazine, rolls 24 for folding longitudinally folding the strip into V-section and a stop 25, which halts the withdrawal of the strip when abutted by the leading end thereof. A notching device (2) whose position relative to the stop is representative of time, then severs from one side of the V-section a terminal portion whose length is representative of the time. The strip is then fed back into the magazine, which is then freed by the latch. The second apparatus, Fig. 4, differs from the first in that the notching device (27) is replaced by a cutting device 37, whose position is also representative of time but whose distance increment for one hour is larger than that of the notching device, and in that there is provided a device 35 for sensing the length of the notch and for moving device 37 towards stop 25 through a corresponding number of increments, so that the length of strip cut-off is representative of the time interval between use of the first and second apparatuses. The strip may be of plastics material having a thin longitudinally central portion to assist folding. The notching device may leave a particular shape on the free end of the side of the strip, from which the terminal portion is severed and sensor 35 may activate an alarm if this shape is not present. The notching device may sever from the strip two portions, the lengths of which represent respectively tens and units of time or distance units. The strip may be magnetically marked (rather than notched) in the first apparatus.

Title: Valve-actuating mechanism having torque overload preventing means
IPC: F16H35/10
Filed: 1976-08-03
Abstract: 1505973 Rotary overload preventing means PHILADELPHIA GEAR CORP 3 Aug 1976 [23 Jan 1976] 32254/76 Heading B3N [Also in Division F2] A drive device for closing a valve V, comprising a closure element 12 with a threaded stem 30 and a valve seat 10, by rotating the stem 30 in a valve nut 15, incorporates an overload protection mechanism to prevent overtightening due to drive motor overrun after switch-off. Driven worm 20 drives a worm gear 21 fixed on a drive sleeve 22 rotatable in housing H. Sleeve 22 drives by means of internal keys or splines 23 a torque sleeve 24 which can therefore slide axially inside the sleeve 22. Sleeve 24 is internally threaded and, in turn, drives an externally threaded member 25 which embraces the square end 31 of valve stem 30 and drives the valve closure element 12 into the closed position, Figs. 1 and 2. When fully seated, the reaction torque exerted by closure element 12 actuates a torque sensing device, not shown, to switch off the motor, not shown, and stops or tends to stop rotating of member 25. Over-run of the motor, however, still applies torque to sleeves 22, 24 the latter of which rides along the threads of member 25 and up against the pre-load of Belleville springs 50 mounted between thrust washers 54, 53 on a member 40 fixed to and forming an extension of valve stem 30, Fig. 3, and the over-run energy is absorbed. On reverse, valve-opening, rotation, the mechanism re-positions itself.

Title: Improvements in induction motor systems
Inventor: HUSKINS DAVID JERVIS
IPC: H02P23/00
Filed: 1961-09-08
Abstract: 1,034,443. Control of A.C. motors. BAILEY METERS & CONTROLS Ltd. Sept. 7, 1962 [Sept. 8, 1961], No. 32267/61. Heading H2J. One of the stator windings of an induction motor is duplicated by an opposed winding, these windings being selectively energizable through respective poles of a double-pole semi-conductor switch, which is also operable to disconnect the two windings from the supply. In another arrangement, a stator winding is connected to the centre secondary tap of a supply transformer, which may be an auto transformer, and is also connected selectively to either end of the secondary winding. A threephase motor has delta-wound stator windings which are connected through the switch to a supply transformer having a double-delta wound secondary winding. Alternatively, the stator windings may be double-delta wound, the sets of windings being arranged in reverse phase sequence and having a common winding. The pairs of ends of the windings remote from the common winding are connected to respective poles of the two-pole switch. This switch may comprise four silicon-controlled rectifiers, arranged in pairs, each pair defining a pole of the switch and the rectifiers of each pair being arranged in parallel opposition. As shown, each controlled rectifier 40 is protected against reverse current by diode 41 and is fed with triggering pulses from transistor pulse generator 44 coupled to protective circuit 46. Zener diode 52 limits positive excursions of the trigger pulse, diodes 50, 52, prevent negative pulses being applied to control electrode 51, and the elements 54, 53, 52 are arranged to limit the trigger voltage at terminal 51 to zero when the anode of the controlled rectifier is negative. The generator 44 may provide pulses in response to an error voltage indicating the displacement of a motor-driven element from a set position. When the rectifier 40 conducts, the generator 44 ceases to supply pulses.

Title: Improvements in or relating to the manufacture of carbon black pigments or compositions containing the same
IPC: C09C1/56
Filed: 1925-12-22
Abstract: 267,625. Whatmough, W. H. Dec. 22, 1925. Carbon papers and ink ribbons.-Composite pigments in a form in which they can be collected as a solid are made by precipitating one or more coloured pigments or dyes in an aqueous suspension of black carbon pigment. The aqueous suspension may contain oleaginous material such as glyceride or hydrocarbon oil, fats, or waxes, in which case the oleaginous matter is precipitated with the coloured pigment and carbon to form a paste or the like. Mineral blues such as Prussian blue or Turnbull's blue or coloured lakes are particularly suitable for modifying the carbon pigment, or aniline dyes, such as crystal violet may be precipitated on the carbon with or without fixing agents such as tartar emetic and tannic acid. The dispersions may include small amounts of dispersing agents such as alkalies or soaps. The pigments may be dispersed in water, water and wax or oil dispersions, or oil such as linseed oil, and may be used for making typewriter carbons or ribbons &c. In example, (1) carbon black is dispersed in water, a solution of potassium ferrocyanide is added, and the solution acidified with hydrochloric acid. The addition of ferric chloride solution produces a homogeneous pigment comprising Prussian blue or carbon particles. (2) Carbon black is dispersed in a dispersion of carnauba wax and water. Prussian blue is precipitated in the solution as before and produces a soft solid pigment useful for carbon papers, ribbons, &c. It can be easily dispersed in an carnauba wax and water suspension. Softer pastes may be made by substituting beeswax or castor oil for the carnauba wax. (3) Carbon black is suspended in water, crystal violet is added, and the mixture heated and agitated. Tartar emetic, tannin, and sodium carbonate in solution are added and the heating and agitation is continued. A purplish-black pigment is produced. Castor oil, carnauba wax, or beeswax may be contained in the original suspension if an oleaginous material is required. Specification 267,207 is referred to.
