Title: Method and apparatus for holding and inflating tires
IPC: B29D30/06
Filed: 1958-03-07
Abstract: 841,499. Moulding tyres. McNEIL MACHINE & ENGINEERING CO. March 7, 1958 [July 5, 1957], No. 7384/58. Class 87(2). In the moulding of tyres having nylon plies, the tyre is moved from the curing press into engagement with closure plates which are moved to form an airtight seal, and the tyre is inflated until the end of the cooling period. As shown, the tyre is cured in a diaphragm press.5 and when the vulcanising period is over, the press opens automatically and the tyre is removed from the press by stripping arms 16, 17 on to a conveyer 25. The tyre moves along the conveyer until it is over a lower plate 46, where it is stopped by rods 95. The plate 46 is then moved upwardly by a toggle linkage 70, 71 which is operated in timed relation with the press through an adjustable link 80 which is pivoted to a pin 11 on the press operating gear. When the tyre is seated between the plates 45, 46, a valve 53 is opened to admit air to the tyre. After cooling, the valve 53 is operated by the press timer to allow the air to be exhausted from the tyre, and the rods 95 are moved out of the way of the tyre by a cylinder 98, the rods being moved to such a position (as shown in Fig. 2) that the bars 90 strike the tyre and forcibly strip it from the plate 45. The plate 46 is withdrawn beneath the conveyer 25 to forcibly strip the tyre from the plate 46. The position of the upper plate 45 may be adjusted by rotation of a shaft 55. The plate is also mounted so that it can have a limited movement which allows it to move upwardly from the position shown in Fig. 7 to the position shown in Fig. 8 when the tyre is inflated.

Title: Process for making elongated cellular articles from thermoplastic polymers
IPC: C08J9/12
Filed: 1953-03-20
Abstract: <PICT:0738779/IV (a)/1> A mobile gel comprising a resinous thermoplastic polymer or copolymer of a monovinyl aromatic compound and a normally gaseous agent dissolved therein is extruded under pressure at a temperature of 60 DEG  to 130 DEG  C. into a zone of lower pressure in an open chamber at substantially atmospheric pressure, the gaseous agent vaporizing and expanding the polymer freely within the said zone but out of restraining contact with the inner walls of the chamber to form a cellular product, the zone of lower pressure being maintained between 50 DEG  and 150 DEG  C., and the product being withdrawn from the chamber.  Suitable apparatus comprises a vessel 1 in which the polymer and gas from a pipe 5 are made into a gel which is extruded through a valved orifice 9 (which may be 1/2 inch in diameter) into a chamber 10 (which may be 4 inches in diameter) in which it expands to form a log 14 the smallest dimension of which may be 2 inches.  The log issues from a chamber on guide rolls 13 which may be driven by an electric motor through variable speed gearing.  The orifice 9 and chamber 10 may be circular, square or rectangular.  The chamber has a jacket 11 for heating or cooling.  Air, nitrogen, carbon dioxide or helium may be blown into the chamber through pipes 12 to displace the vapours of the gas escaping from the expanding gel, and the air &c. may be heated to prevent cooling of the gel, in which case the jacket 11 may be omitted.  The vapours may be recovered.  The material may be a polymer of styrene, vinyltoluene, vinylxylene, ethylvinyl-benzene, para - chlorostyrene, meta - chloro-styrene, para - isopropylstyrene, para - bromostyrene or ethylvinyltoluene or a copolymer of two or more of such compounds, or a copolymer of styrene and alpha-methylstyrene.  The normally gaseous agent may be methyl chloride, methyl ether, propylene, butylene or dichlorodifluoromethane, and may constitute 6 to 25 per cent by weight of the resinous material.  Specification 661,002 is referred to.

Patent GB-644649-A (GB)
Title: Improvements in the milling of fabric and in apparatus therefor
IPC: D06C29/00
Filed: 1948-03-16
Abstract: 644,649. Milling fabrics ; measuring continuous lengths. BATES, E. B. March 16, 1948, No. 7855. [Classes 42 (i) and 42 (ii)] In the milling of fabric, in which the fabric in the form of an endless band is passed repeatedly through the milling machine, there is obtained at each of successive passes of the band through the machine a measurement which is representative of the length of the band at that pass, and the milling process is halted when the said measurement drops to a predetermined value, the reduction of length of the fabric being taken as an indication of the increase in weight per unit area produced during milling. As shown, the lower squeezing roller 3 of a rotary milling machine 1 is connected through worm gearing 8 to a lengthindicating device 9 having two indicating fingers 10, 11 movable over a dial 12. The upper squeezing roller 2 is spring-mounted at 4 so as to lift at each pass of the seam 7 in the band F of fabric. Each time roller 2 lifts it raises a plunger 15 which acts through a spring 16 to raise a rack 18 and thereby rotate a pinion 20 which drives a cam-shaft 21 clockwise through 120 degrees through pawl-andratchet mechanism 22. At the first pass of seam 7, cam-shaft 21 moves to the position shown and finger 10, together with an attached ratchet wheel 28, commences to move clockwise. At the second pass of the seam, shaft 21 is rotated to a position where a cam 23 moves a, lever 34 to disengage a clutch in the drive to finger 10, thus halting the finger at a reading indicative of the length of the band F. At the third pass of the seam the clutch remains disengaged and a cam 24 disengages a pawl 25 from ratchet wheel 28, allowing finger 10 to be returned to the zero position under spring influence. At the next pass of the seam the mechanism reverts to the position shown, pawl 25 and the clutch are re-engaged, and finger 10 again commences forward movement. Finger 11 is pushed forward by finger 10 and remains to indicate the maximum reading when finger 10 returns to zero. As the fabric shrinks in length, finger 10 will indicate progressively decreasing lengths which can be readily compared with the original length indicated by finger 11. If the machine is run with no fabric in it, fingers 10 and 11 are driven round until they engage and shift a stop 36, causing lever 34 to be swung to the clutch-disengaging position. When the speed of operation of the machine is constant, the length measurement may be replaced by a time measurement, successive lifts of roller 2 being utilized to start, stop and re-set a stop watch.

Title: Apparatus for measuring temperature or determining colour difference
IPC: G01J5/60
Filed: 1959-03-06
Abstract: 911,645. Photo-electric temperature measurement. SHAW INSTRUMENT CORPORATION. March 6, 1959 [April 1, 1958], No. 7905/59. Class 40 (3). [Also in Group XXXVI] A photo-electric temperature measuring device and colour comparator which functions by determining the ratio of the energy radiated by the source in two separate narrow frequency bands is arranged so that changes in distance, reflectivity, and overall light intensity are cancelled out over a wide range of values. The device consists of a light-sensitive element such as the photo-multiplier tube 7 which views the source through a rotatable filter 3 and a small window. The filter comprises a major colour band part 3a, typically of red plastic or glass, and a smaller part 4 which may be of blue plastic or glass. It is arranged that when the filter is rotated the major colour band filter is in the radiation path for approximately ninetenths of the time. The speed of rotation of the filter disc is made high; in a typical case it is 3,600 r.p.m. The tube 7 is supplied by a rectifier circuit 10, 11 and its anode connected through resistor 18 to a reference voltage source 19. When the radiation falling on the tube is strong enough to provide an output voltage across load resistor 16 sufficient to overcome the bias, or reference, voltage of battery 19 it controls the current flow through amplifier 21. This current flow affects control valve 25 to alter conditions in the rectifier circuit in such a way that the potential across load resistor 16 is returned to its normal value. There is a time lag in the correcting circuit and the effect of the feedback arrangement is such that above a threshold level there is no change in output potential on line 30 for variations in radiation intensity falling on the detector 7 unless such changes are very rapid. Rapid changes are produced when the filter 4 moves across the field of view and each passage of the filter produces in the output line 30 a square waveform of an amplitude proportional to the intensity variation between the radiation passed by the two filters. These square pulses are superimposed on a steady potential blocked by capacitor 30a but themselves pass to a peak reading voltmeter circuit based on double triode valve 34 and diodes 31 and 52. The indicator 9 in this circuit gives an indication dependant on the temperature of the radiating source having regard to Wien's law and the pass bands of the filters employed; it may conveniently be calibrated directly with a temperature scale. It is stated that the apparatus may also be used for comparing a sample colour with a standard colour. For greater accuracy the detector 7 may be placed in an enclosure maintained at a constant temperature by a thermostatically-controlled electric heater (Fig. 6, not shown).
