Title: A time-recording lock
IPC: G07C1/32
Filed: 1958-08-25
Abstract: 845,915. Time-checking apparatus. OLDHAM, F., and OLDHAM, A. Aug. 25, 1958 [Sept. 11, 1957], No. 28597/57. Class 106 (4). [Also in Group XXV] Relates to time-recording locks suitable for locking receptacles and of the type comprising a rod adapted to be inserted through a plurality of eyelets or apertures and to be secured against removal therefrom. According to the invention the lock comprises a casing 10, 11 housing a clock and having a socket 24 adapted to receive one end of a headed rod 36, there being means whereby the rod 36 may be locked against removal from the socket and means operable by locking of the rod for starting the clock, so that the time at which the rod is secured can thereafter be ascertained from the clock. As shown, the rod 36 is formed with a slot 40 which is engageable with a pin 25 in the bore of the socket 24 and with a keyway 38 which is engageable with a tongue 27 of a spigot 26 which is rotatably mounted in the bore of the socket. A spring-loaded pawl 31 within the casing bears on an edge of a head portion 28 of the spigot, and a spring 34 engages with the balance wheel 35 of the clock. The arrangement is such that after the socket 24 has been passed through eyelets in the mouth of a bag, the rod is inserted into the bore of the socket 24 to engage the tongue 27, in which position the slot 40 in the rod is engaged by the pin 25, thus to permit the rod and the spigot to be rotated until the pawl 31 engages a notch 29 on the head portion 28. In this position the rod is locked against rotation and the spring 35 disengages from the balance wheel to automatically start the clock. The clock includes means such as a star-wheel visible through an aperture in the cover 10 of the clock casing for recording the number of days elapsed since the starting of the clock. The cover is secured by a. bayonet-type connection with the body 11 of the casing and a latch plate 20 rotatable by a key-operated cylinder lock. A cap 22 over the key-hole retains a paper seal. The cap is retained by a pin (not shown) integral therewith which extends through a stationary part of the lock and engages a resilient strip 23. When the bag is to be removed, the cover 10 is unlocked and removed, the pawl 31 isdisengaged from the catch 29 by a suitable key to stop the clock and the rod 36 rotated and withdrawn to free the bag.

Title: Improvements in textile fabric and method for producing the same
IPC: D04H13/00
Filed: 1949-11-08
Abstract: 703,345. Fibre coated fabrics. OAKLEY, J. L. D. (International Cellucotton Products Co.). Nov. 8, 1949, No. 28609/49. Class 140 A textile fabric comprises an open-mesh web formed of interlaced threads and adhesive, e.g. plasticized polyvinyl acetate, bonding some or all intersecting thread portions in the web, portions of some of the threads intermediate such intersections being substantially free of adhesive so as to preserve the normal softness of the intermediate thread portions whereby the normal softness of the web before stabilization thereof is preserved to a high degree. An applique of non-woven fibres may be adhesively attached to the open-mesh web. In the process illustrated in Fig. 2, a web 1 of open-mesh fabric is drawn from a supply roll 6 and guided by rolls 7-7 into contact with an adhesive applying roll 8 to the surface of which liquid adhesive supplied from a reservoir 9 is applied by a doctor blade 11 ; if a speed differential is maintained between the surface of the roll 8 and the moving web 1, the viscous adhesive is scraped off the roll by the projecting intersections of the threads in the vicinity of which adhesive tends to concentrate in blobs leaving intermediate portions relatively uncoated. The deposited adhesive is, according to its nature, allowed to set or dry or is set as by means of a hood 12 which may discharge cooled or hot air on the adhesive bearing surface of the web, and the web is wound into a roll as at 6a for subsequent use as at 6b; alternatively the adhesive may remain wet or partly set or dried and the web proceed directly to the next stage of operations. A non-woven bat of cotton or other fibres is fed towards a divellicating roll 13 whereby separated fibres are deposited as a refined bat 5c on a continuously travelling wire screen belt 14 under the control of a suction box 15: the bat 5c may be rolled on itself for future use or, as shown, fed to a defibering roll 16 whereby a light film of uniformly distributed fibres is deposited under the control of a suction box 17 on to the adhesive bearing surface of the web 1. The fibre-coated web is guided by rolls 18 around a portion of a calender roll 19 which has a compressible surface and is supported by - rigid roll 20 and co-operates with a heated roller 21 to press the fibre film and web tightly together and reactivate the adhesive or dry adhesive solution so that some fibres adhere to the web and others mutually engage. The divellicating rollers may be replaced by other equipment such as garnetting or carding machines for delivering opened fibres. The direct application of liquid adhesive may be avoided by employing a web having in some or all its threads and discontinuously distributed along the lengths thereof, fibres of a thermoplastic material suitable for reactivating by either heat or pressure alone, or solvents of the thermosplatic material may be used to render the material sticky.

Abstract: 1460886 Foundry moulding machine INVENTIO AG 8 July 1975 [10 July 1974 18 June 1975] 28663/75 Heading B3G A foundry moulding plant includes two units, each for producing a different part 1 or 2 of a mould, and a station IV where the parts are assembled. Each unit comprises a rotary carrier 11 or 12 rotatable about axes 15 or 16 conveying mould frames 7 or 8 to a station 4 or 5 where sand is introduced into the frames and compacted. Each unit has four mountings 13 each supporting a mould frame and carried by an arm 14 rotatable about its axis through at least 180 degrees; each arm extends from a plate 22, Fig. 5, movable vertically on rods 21 by piston and cylinder units 28. The mountings of the carrier 11 are located in a horizontal plane above that of the mountings of the carrier 12 so that at the assembly station the mould parts in one frame are located directly above the mould parts in the adjacent frame. At the assembly station a platform 38 is raised to receive the mould parts released from the superposed frames; alternatively the frames may be lowered to position the assembled mould on a conveyer belt. The carriers are moved through intervals of 90 degrees and, after the sand compaction stage, the frames move through core insertion stations II and III before reaching the assembly station. The stations 4 and 5 each include a pattern on to which the frames are lowered, in turn, and after sand compaction the frames are raised and rotated through 180 degrees for the core insertion stage. The mould frame may comprise plates 44, 45, Fig. 7, linked together with pins 46 slidably engaging bores 41 in its mounting. A piston and cylinder means 42, 43 expands or retracts the frame. In a modification mould boxes may be fed to the units by conveyers and received either by frames as in Fig. 7 or by grippers comprised by plates 44 only. Moulds comprising three or more parts may be produced by the plant.

Abstract: 1,215,788. 788. Automatic temperature control systems. LANDIS & GYR AG. June 6, 1969 [June 14, 1968], No.28818/69. Heading G3R. A three point regulator comprises two electromagnetic relays each having an operating winding A, B controlled by a transistor 1, 2 connected as one branch of a differential amplifier with a sensing resistor e.g. 8 connected directly in the base circuit of one of the transistors. The sensing resistor may form any branch of bridge network 6-9. As the amplifier is only responsive to the  difference between the bridge diagonal voltages it is insensitive to temperature change characteristics of the transistors. Resistor 8 may be responsive to temperature in a room and contacts a; b may control a reversing motor varying the supply of a heating of fluid or controlling a ventilating system. Variation of the sensed conditions above or below a determined value will result in either winding A or B being energized.  To render the operating point of transistors 1, 2 independent of the characteristics of the relays, these may be controlled by additional transistors (14, 15) Fig.3 (not shown) connected to the outputs of transistors 1, 2. A Zener diode (16) stabilizes the voltage supply to transistors 14, 15. A regenerative action may be provided by resistors (20, 22). In a further arrangement Fig.4 (not shown) above and below the determined value one relay operates during the discharge time of a capacitor (34 or 35) then releases while the appropriate capacitor is recharged in a cyclic manner.

Abstract: 1,159,311. Spinning yarns. L. B. (PLASTICS) Ltd. 25 Sept., 1967 [28 June, 1966], No. 28830/66. Headings DID, D1F and D1W. Thermoplastic thread or strip material e.g. a rod or tube of circular cross-section, ribbon or flat strip, twisted so that differently coloured surface portions give an appearance of two or more threads intentwisted, is produced by subjecting the material to a twisting action as it is drawn from a reel by advancing rollers and passing the twisted material successively through heating and cooling zones e.g. hot and cold water baths provided in elongated channels, so that the material is softened to relieve stresses due to twisting and then chilled and set to remove any tendency to untwist. The pairs of advancing rollers whereby the thread &c., is passed to the heating zone and withdrawn from the cooling zone are driven from the same source, through belt and pulley, chain and sprocket transmission and the speed thereof may be varied e.g. by an electric speed controller or cam mechanism, to cause variation in twist along the length of the thread &c. As shown, thermoplastic tube or rod material 26 is withdrawn from a rotating reel 25 through the tip of a nose portion 31 of a housing 30 normally weighted by arm 32 and rod 33 slidably carried in guide 34. Twist is imparted by the action of a flyer carrying the material by means of an eyelet 44 on a bracket 43 attached to a disc 38a which is rotatable, frictionally driven and downwardly urged by a spring 40, on a peg 37 carrying a bush 38 and fixed within a hole 36 in the reel spindle 20 by a set screw 39. In a woven fabric, the warp and/or weft may be formed wholly or partly of the twisted thread &c.

Title: Improvements in and relating to line scanning time base for television receivers
IPC: H04N3/18
Filed: 1954-10-13
Abstract: 797,517. Television. SAUTIER & JAEGER. Oct. 13, 1954 [Oct. 16, 1953], No. 29474/54. Class 40 (3). [Also in Group XL (c)] A television receiver employing an E.H.T. generator controlled by line fly-back signals is arranged to produce a constant raster size when receiving signals utilizing different scanning line frequencies. As shown in Fig. 3, the received line synchronizing signals are supplied to the control grid of a conventional thyratron sawtooth generator L1 and the resulting sawtooth wave fed to the control grid of a variable slope pentode L2, the cathode biasing resistor Rc, the control grid resistor Rg and the screen grid resistor Re of which are so adjusted that the input sawtooth wave, due to a high linescanning frequency and which (for a given set of circuit constants for L1) has a smaller amplitude than that produced by L1 due to a lower line-scanning frequency is amplified to a greater extent than a sawtooth wave due to a lower line-scanning frequency. In this manner a partial compensation is effected for the change in the amplitude of the scanning sawtooth waves when the line-scanning frequency is changed and a further compensation is effected by the change produced in the E.H.T. voltage (produced from the fly-back signals in the sawtooth waves supplied by L2 via auto-transformer AT and rectifier L3) due to the fact that the slope of the fly-back signals is greater for high line-scanning frequencies (and so produces a higher E.H.T.) than for low line-scanning frequencies. Additional compensation also results from the reduction in efficiency of the tube deflecting coils HL, designed for normal operation with a high line-scanning frequency, when low line-scanning frequencies are utilized and, in the case of the latter frequencies, the effect of any residual reduction in E.H.T. voltage on the brightness of the reproduced picture is compensated by the slower speed with which the fluorescent screen is scanned. In addition to providing the required compensation in scanning wave amplitude, the variation of the operating point on the gridvoltage/anode-current characteristic of valve L2 also effects a compensation for the difference in linearity between the high and low frequency sawtooth waves produced by L1.
