Title: A process for polymerising vinyl chloride
IPC: C08F267/04
Filed: 1954-08-12
Abstract: Porous granular polyvinyl chloride is made by the suspension polymerization of vinyl chloride in an aqueous solution of a heteropolymer of vinyl acetate and maleic acid or its anhydride, in the presence of a polymerization catalyst and a small amount of an alkylene oxide condensation product of a monoester of a saturated fatty acid having 12 to 24 carbon atoms in the molecular and a polyhydric alcohol having not more than four alcoholic groups, at least two being primary alcoholic groups, and the alkylene oxide having not more than four carbon atoms in the molecule.  The polymerizable mixture may also contain a small amount of an uncondensed mono-ester of a saturated fatty acid having 12 to 24 carbon atoms in the molecule and a polyhydric alcohol having not more than three carbon atoms in the molecule, e.g. glycerol monostearate, pentaerythritol monostearate, ethylene glycol or diethylene glycol monostearate.  Fatty acids mentioned are lauric, tridecylic, myristic, palmitic, margaric, stearic, nondecylic, archidic, and lignoceric.  The polyhydric alcohol may be ethylene, diethylene or triethylene glycol, pentaerythritol, glycerol or erythritol. Suitable alkylene oxides are ethylene, propylene, and butylene oxides.  Specified catalysts are lauroyl, benzoyl, di-t-acetyl, propionyl, butyl and toluyl peroxides and mixtures.  The porous polyvinyl chloride can be blended rapidly with plasticizers, e.g. dioctyl phthalate, and the blend may include a stabilizer such as glycerol mono-oleate.

Title: Improvements in and relating to vapour generators
IPC: F22G5/04
Filed: 1953-08-25
Abstract: 729,990. Water-tube steam boilers; steam superheaters. FOSTER WHEELER, Ltd. Aug. 25, 1953 [Aug. 27, 1952], No. 23436/53. Classes 123 (2) and 123 (3). In a steam generator comprising a furnace 10 fired by oil burners 12, the combustion gases leave the furnace through a top outlet 32 or a bottom outlet 28, the latter leading to a vertical passage 26 separated from the furnace by a partition 24 lined with steam generating tubes 38 and housing a superheater 34. Gases flowing upwardly in the passage meet the gases from outlet 32, the combined gas stream then flowing to and fro between partitions 22a, 22b, 22c to heat steam generating tubes 16a, 16b, and 16c and finally discharging through an outlet 14. The tubes 16a, 16b, 16c and lining tubes 38 extend respectively from water drum 20 and header 40 to a steam and water drum 18 from which steam passes to the superheater 34. The relative dimensions of the outlet from passage 26 and the furnace outlet 32 are such that a major part of the furnace gases normally enter the passage 26. The degree of superheat is controlled by reducing this flow of gas by forming a screen of high velocity gas across furnace outlet 28 for which purpose furnace gases and air are withdrawn through outlets 50 and 60 respectively by a blower 72 which discharges the mixed gases through nozzles 47 and 68 disposed above and below the outlet. The effectiveness of the screen in restricting the gas flow and hence the final superheat temperature is determined by the settings of dampers 52 and 62 in outlets 50 and 60 respectively and of dampers 56 and 66 in the inlet ducts to the nozzles. Instead of flue gas, air or steam may be used to form the screen.

Title: Improvements in and relating to photo-mechanical printing
IPC: G03F7/14
Filed: 1922-09-08
Abstract: 202,601. John, R. Aug. 16, 1922, [Convention date]. Photo-mechanical printing surfaces.-In making a gelatin or colloid printing-surface, more especially for litho or offset work, the colloid film. is sensitized with a chromic salt, exposed and immediately subjected to the action of a selective hardening agent consisting of alcohol and/or ether. The colloid film may also be hardened after removal of the chromic acid salt by alcohol or by heating, and the colloid film may also be hardened, as by formaldehyde, before sensitizing- the film. The printing-plate can be damped with water only, no glycerin or other agent being necessary, and the necessity for periodic gumming is avoided. The plate can be sensitized after coating it with colloid, or :he sensitizing salt can be added to the gelatin coiting solution provided the temperature is kept below 130‹ F. A thin sheet of metal, celluloid or other material may be used. The metal plate is grained or roughened to facilitate, adhesion of the coating, but not for reticulating the printing-surface. A gelatin coating consists of 2250 grains of hard gelatin in 32 ounces of water, the gelatin being soaked in cold water and brought into solution by heating to 120‹ F. The plate is coated at this temperature to a thickness of .088 to .0012 inches, and dried. The gelatin is next hardened in a bath of alcohol (32 ounces) and 40 per cent formaldehyde (1 ounce), dried, washed in running water, and again dried. The sensitizing solution contains ammonium bichromate (450 grains), alcohol (32 ounces), and water (16 ounces), to which a light-restraining agent (e.g. 90 grains of erythrosine) may be added. Exposure, is effected as soon as possible. A half-tone, negative with a very fine screen or grain may be used. After exposure, the plate is treated before washing out the bichromate in a bath of grain alcohol of high proof (95 per cent or higher), or of ether, or ether and alcohol, in order to increase selectively the hardening action in the exposed parts without hardening the unexposed parts, and leave the film in a dry state. After washing to remove the soluble bichromate remaining, the plate may again be treated with alcohol to further harden the hardened portions. The plate is then heated in an oven to 400‹ F which completes the hardening of the exposed parts, gives a permanent printing-surface., toughens the unhardened parts without affecting their water receptivity, and increases the adhesion of the gelatin and the grained plate.

Title: Method of producing the corner joints of cycle frames
IPC: B23K11/00
Filed: 1926-09-22
Abstract: 269,059. Koln-Lindenthaler Metallwerke Akt.-Ges. June 29, 1926, [Convention date]. Tubes. - The joints between the tubular frame members and connecting socket members of cycle frames are made by tightly fitting the frame member into the connecting sockets and then completing the joint by electric spot welding. In constructing the upper corner joint of the steering head, Fig. 1, the socket member 2, for the reception of the upper frame tube 3, only is completed, the main socket 1 for the steering head tube being left as shown in Fig. 2, so as to enable an electrode 4 to be inserted in the tube 3 for the purpose of cooperating with a second electrode 5 to effect the welding 6. The walls of the socket 1 are then bent to cylindrical shape and the adjacent edges thereof welded together, after which the steering head tube 9 is inserted in the socket formed thereby and connected to it by spot welding. The other joints of the frame are constructed in a similar manner with the exception of the connections of the tubes 23 to the crank bearing-box 17, Fig. 11, in which case the inner electrode 4 is bent at right-angles and is provided at the bead with lateral welding projections 22

Title: Improvements in extending tables
IPC: A47B1/02
Filed: 1937-08-30
Abstract: 501,526. Extending tables. TARR, R. J. C. Aug. 30, 1937, Nos. 23650/37 and 18835/38. [Class 52 (iii)] In extending tables having an extension leaf e adapted to be raised into position of use by the -outward movement of a sliding table top member t, the sliding top member is provided with a manually operated lever d movable into engagement with a member f associated with the support p of the extension leaf to initiate its downward movement, whereby the extension leat is lowered by pulling out the sliding top member and pushing it in again while operating the lever d. As shown in Fig. 4, the extension leaf e rests upon a, platform p carried by parallel links l and during the outward movement of the sliding leaf t when extending the table a block b fixed under the leaf t engages a pull-rod r connected to the platform p to raise the extension leaf into position for use, the leaf being guided by a headed screw s working in a slot in the partition or back rail n. To 'close the table the sliding leaf t is pulled out slightly to the position shown in Fig. 4, the lever d operated to bring its nose into the path of a rod f rigidly fixed to the platform p, and the leaf pushed in so that the lever strikes the rod f to start the downward movement of the platform. There may be two extension leaves and two sliding leaves separately actuated, or a single extension leaf and two interconnected end leaves. Instead of resting directly upon the platform p the extension leaf may be linked to it by further parallel links :and have depending guides. Fig. 9 shows a modification in which the rod f carries a wheel j adapted to be engaged by a block m fixed beneath the sliding leaf t so that when this leaf is pulled out the rod ,f rides up the slope n<2> formed above the table rail o. A spring v keeps the rod f seated upon the slope n<2 >and out of the path of the lever d in its normal position. Fig. 11 shows two sliding leaves t interconnected for simultaneous operation by cords u passing over pulleys y and a single extension leaf e resting on two platforms p pivoted to links l connected by a lever b<1> so that when one platform p is lowered by the lever d operating the rod f the other platform is correspondingly lowered. In this form the pull-rods r are replaced by chains a. The sliding leaves may be interconnected by levers pivoted to the table underframe. Fig. 1'.7 shows a modified method of raising the extension leaf e by wire cranks m<1> loosely pivoted to the platform p and resting upon the runners q of the sliding leaves t. A block n<1> fixed to the runner catches the crank m during the e outward movement to raise the platform. A block q<1> on the extension leaf contacts with the table rail p<1> to retain the leaf in the raised position. The cranks m<1> may be replaced by bevel blocks fixed to the side of each runner q and contacting with a,bevel on the end of the platform p.

Abstract: 964,928. Exciting dynamo-electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 5, 1963 [June 20, 1962], No. 23780/62. Heading H2A. The power output of a D.C. traction generator is made to closely approach the ideal constant power characteristic by having two field windings 8, 9 with one, 8, separately excited and the other, 9, connected in shunt with the generator and in series with an auxiliary voltage source. The auxiliary voltage source comprises a resistor supplied from the rectified output of inductor alternator 2. Tapping points on the resistor are connected through diodes A, B, C to one side of field winding 9 and diode A is connected in the opposite sense to the other. At low current requirements, e.g. at starting, diode A conducts and the field produced by winding 9 bucks that of winding 8 to reduce the effective field in the machine. As the motors accelerate a higher voltage is required and the current passing through diode A decreases and diodes B, C become successively conducting. The inductor alternator also supplies the auxiliaries at T3, T4 and the energization for field 8.
