Title: Improvements in or relating to a method of making an expanded material and the product resulting therefrom
IPC: C08J9/30
Filed: 1948-07-28
Abstract: Expanded material is made by forming dispersed bubbles in a solution of polyvinyl alcohol containing less than 10 per cent residual hydrolysable material in the molecule, and reacting in a mould the alcohol with formaldehyde in the presence of an acid catalyst having a dissociation constant of at least 10-2, e.g. sulphuric, p-toluene sulphonic, hydrochloric, phosphoric, nitric and hydrobromic acids. Bubbles are formed in the solution by beating to a froth or by including chemical agents, e.g. calcium carbonate, sodium bicarbonate, or finely divided magnesium or zinc, which react with the acid catalyst to produce a gas.  The formaldehyde may be added as a gas, in aqueous solution, or as paraformaldehyde, hexamethylene tetramine or methylal, and wetting agents, e.g. sorbitan monolaurate, polyoxyalkylene derivatives of sorbitan monolaurate, stearate or oleate, sodium lauryl sulphate, alkali metal salts of alkyl-aryl sulphonates, e.g. di-isobutyl or di-isopropyl naphthalene sulphonate, and the polyethylene ethers of a long chain aliphatic acid may be present. Dyes, e.g. phthalocyanin, pigments, e.g. iron or chromic oxide, and fillers, e.g. wood flour, glass wool, kieselguhr or an abrasive such as pumice may be added.  Sheets may be moulded directly or formed by slicing and heat pressing.  Specifications 246,817, [Class 2 (iii)], 377,678, 494,769 and 573,966 are referred to.

Title: An improved method of controlling a straight-bar knitting machine and means therefor
IPC: D04B15/66
Filed: 1958-06-25
Abstract: 865,364. Knitting-machines. MONK (SUTTON IN ASHFIELD) Ltd., S. A., and MONK, S. A. Sept. 17, 1959 [June 25, 1958; Jan. 22, 1959], Nos 20286/58 and 2333/59. Class 74 (2). Control mechanism for a straight-bar machine comprises a series of course counters 1 ... 10 each of which controls the fashioning or otherwise operations during the production of a fashioned garment. For example, as illustrated, after transfer of an initial rib portion B the course counter 1 counts the courses of an initial portion of fabric C during which fashioning is not performed and results in straight selvedges. On completion of this initial portion the counter trips a switch which energizes a solenoid coupling two control switches 1a, 1b the positions of which have been pre-selected to determine by the switch 1a whether widening by one or two needles or narrowing by one or two needles is to be effected in a course, and by the switch 1b the frequency at which the widening or narrowing operations are to be performed. The switches 1a and 1b are mutually effective by the switch 1b removing a stop controlling an appropriate cam which operates a switch in the circuit of the other switch 1a. Consequently, every so many courses as determined by the switch 1b, the fashioning points narrow or widen the fabric one or two needles as determined by the switch 1a. In the illustration, the fabric is widened as indicated at D. Simultaneously, the solenoid operated by the counter 1 also couples into the control circuit a second counter 2, which during production of the portion D, counts the number of courses and on completion of the portion as predetermined by the setting of the counter 2 operates a further switch controlling a solenoid which promptly couples two succeeding switches 2a, 2b into the circuit, and also the next counter 3. In similar fashion, therefore, the whole garment is completed and on completion the last counter trips a switch to stop the machine.

Title: Improvements in or relating to rotary brushes
IPC: A46B13/00
Filed: 1947-07-28
Abstract: 655,263. Stocks; rotary brushes. OSBORN MANUFACTURING CO. July 28, 1947, No. 20365. Convention date, Feb. 12, 1941. [Class 19] An annular brush section is mounted on a disc-like adapter provided with outwardly projecting inclined arms having axially extending portions by seating the section on said portions and then moving the arms . so as to decrease their inclination to the plane of the adapter, said portions being thereby moved outwardly to seat the section more firmly. In the drawings the adapter 1 has a central opening for mounting it on an arbor or mandrel and arms 3 extend radially and then axially to seat the section and finally radially to embrace one side of the section. Alternating with such arms are other arms 4 formed of deformable, preferably resilient material and these are inclined toward the side embraced by the arms 3, then bent back axially to seat the section and then radially to embrace the other side of the section. The brush section comprises an annular channel form back 5, the sides of which are formed into alternate flat depressed areas. 8 and raised somewhat flaring lands 9. When the section is mounted on the adapter the arms 4 embrace the lands and the arms 3 embrace the depressed areas, or when two sections are to be clamped together, Fig. 6, the arms 4 also engage depressed areas. When sealing a single section on the adapter the section is first engaged with the portions 10 of arms 3 (see Fig. 2), and seated on the axial portions 11 of arms 4, these portions being then tensioned, i.e. pulled to the left, Fig. 7, to more firmly seat the section. The ends 12 are then turned radially to embrace the lands 9. When a plurality of sections are assembled they are placed land to land and depressed area to depressed area to provide ventilating openings. The depressed areas of one side are staggered relative to such areas of the other side and the portions 11 of arms 4 pass through the openings 13 between the arms of adjacent adapters and additionally embrace one or more adjacent sections. Specification 655.262 is referred to.

Title: Device for adjusting the count, thickness or cross-section of a sliver in textile spinning machines
IPC: D01H5/40
Filed: 1955-07-14
Abstract: 778,831. Regulating thickness of textile slivers. CALZONE, F. July 14, 1955 [July 22, 1954], No. 20444/55. Class 120 (2). A device for adjusting sliver thickness in spinning machines includes a pair of measuring rollers interposed between feed and delivery rollers and which act, as a result of variations in thickness of the sliver, to vary the speed of the feed rollers through hydraulic mechanism. Variations in thickness of the sliver N cause a beam 16 to oscillate thereby inducing fluid to flow between a chamber 19 and a cylinder 21. Corresponding movements of a plunger 22 occur, which are transmitted through a pivot 24 to a rod 8 that is reciprocated by a cam 5 which is fixed to the shaft of the lower delivery roller and oscillates an arm 10 to drive the lower feed roller 2 through ratchet mechanism 12. Downward movement of the plunger 22 results in an increase in the effective length of the arm 10. The control mechanism is duplicated on each side of the rollers. Instead of the ratchet mechanism 12, a friction clutch may be employed.
Patent GB-695337-A (GB)
Title: Improvements in or relating to the alkylation of isobutane
IPC: C07C2/60
Filed: 1951-08-30
Abstract: In the alkylation of isobutane with ethylene in the presence of an active aluminium chloride catalyst to form an alkylate comprising a hexanes fraction which is substantially 2,3-dimethylbutane, aluminium chloride is continually added to the reaction zone in an amount of 0.15-0.20 lb. per U.S. gallon of alkylate sufficient to convert at least 95 per cent of the ethylene and to maintain the 2,3-dimethylbutane content of the hexanes fraction above about 95 per cent, the rate of addition of aluminium chloride being increased when the ethylene conversion falls below 95 per cent and decreased when the 2,3-dimethylbutane content falls below about 95 per cent.  The reaction is started by adding aluminium chloride within the stated range to give substantially 100 per cent ethylene conversion but less than 95 per cent 2,3-dimethylbutane in the hexanes fraction, and thereafter varying the rate of addition.  Reaction temperature is about 45-140 DEG  F. and pressure sufficient to maintain the liquid phase.  The isobutane feed may be split, one part passing via a heater and an aluminium chloride saturator to the reaction zone to which the remaining isobutane and ethylene are also fed.  At least part of the alkylate is freed from catalyst and fractionated to give ethane and lighter overhead, a side-stream of butanes, and the desired alkylate as bottoms.  Part of the overhead and of the bottoms are passed to continuous analyzers, e.g. of the infra-red type, where absorption of light by the samples causes electric impulses which control valves to vary the rate of flow of isobutane through the heater or the heat input thereto and therefore control the amount of aluminium chloride carried to the reactor.  In an example, the molar ratio of isobutane to ethylene is 5 : 1, temperature is 115 DEG  F., and hydrogen chloride equivalent to 75 mole. per cent of the aluminium chloride is used as promoter.  The liquid space velocity of the feed should be not less than 1 vol./vol. catalyst/hour.

Pleating. - A pleating - machine comprises a heated bed 30, an interchangeable plate 23 bevelled at its edge to co-operate with knives 22, bars 3, and grippers 10. The knives are notched at 34 to form the folds which are gripped by the grippers 10. There are a series of grippers, bars and knives arranged in a comb-like formation, the grippers being arranged between adjacent bars. The grippers are carried by a head 9 connected by links 6 to a roller on a cam 13" mounted on a shaft s which also carries an eccentric 13<1> operating a rod 29 and a cam 13 operating a roller 13<a>. The roller 13<a> is carried by a lever 11 which is also provided with a roller 28<a> engaging a. slotted link 21, which communicates the movement to the shaft 16, to raise the knives clear of the fabric. The road 29 transmits motion to a lever 15 which is provided with a bifurcated end in which the shaft 16 is carried. The movement is obtained through the medium of a roller on the rod 29 engaging a slot 15a in the lever 15. The lever 15 is pivoted at 27 and when oscillated by the rod 29 moves the knives horizontally. The fabric is fed over a series of transverse bars 14. The position of the roller 28a in its slot determines the height the knives are raised above the fabric and the position of the roller 15<a> in its slot determines the reciprocating movement of the knives.

Title: Improvements in or relating to splash guard attachments for road vehicles
IPC: B62D25/18
Filed: 1923-08-13
Abstract: 225,909. Graveley, H. V. N. Aug. 13, 1923. Lateral-splash guards.-A splash guard for vehicle wheels is raised by a spring when it encounters an obstruction, and is returned to operative position by power-driven mechanism. Movement of the guard b by an obstruction causes a spring-controlled hemispherical member f, Fig. 3, to raise a rod g which disengages a pawl h and allows a movable frame a carrying the guard to be raised in a fixed frame d by a spring j and a bell-crank lever k. For damping the action of the spring just before the completion of the lift of the frame a, a dash-pot j<5> is used. On the guard reaching its uppermost position a pin l engages a spring-controlled lever m, causing it to turn and bring a wheel o into engagement with a wheel o<1> on the road wheel hub, thus rotating a pulley n and winding thereon a cord n<1> connected to the movable frame. A spring-controlled detent p engaging the lever m holds the wheel o in gear and is held in position by a feather on the rod g, travelling between studs on the detent until the guard approaches its lowermost position, when the gearing is released by an adjustable finger q. The feather also serves to move the detent p and thus the gearing to the disengaged position, when the guard is prevented from reaching its lowest position by an obstruction. When the guard is moved upwardly in relation to the movable frame, owing to the engagement of a pin with a spiral groove f<5> in a sleeve f<4>, the rod g is caused to turn slightly, and the feather of the rod acts on the studs upon the detent to remove it from the end of the lever m. The other end of the guard is also supported by a member f and a pin r. The guard b and a rear casing u of sheet metal are fixed on bridge-pieces t<1> and pins t<2>. The gearing is provided with a silent gripping pawl which is thrown out by centrifugal force. The gearing may be operated from the motor &c. The cord n<1> and the pulley may be replaced by a rack and pinion. The rod g may be resilient and flexed to act upon the detent. Spring attachments may be used between the various parts, and the guard may be secured in its uppermost position. The guard attachment is mounted on a supporting-frame fixed to the axle.
