Title: Improvements in or relating to coin-freed apparatus
IPC: G07F11/16
Filed: 1928-01-12
Abstract: 309,526. Thrissell Engineering Co., Ltd., (formerly Brecknell, Munro, & Rogers, Ltd.), and Dolman, H. J. Jan. 12, 1928. Delivery of articles stored in piles; coin action, with stationary coin forming abutment. - The bottom article of a pile is delivered by a drawer 1, Figs. 1, and 7, sliding in guides 4, 5 on a base plate 3 and having a screw 8 passing through a slot in the base plate. The drawer is formed with a front plate 12, back plate 11 and top 10 providing a recess 13 open at the bottom. It has a lower plate 14 integral with the wall 11 and a top plate 22 attached by screws to the plate 14. The drawer is normally prevented from being pulled out by a handle 2 by the nose 18 of a detent 16 engaging a fixed rack 20 located in the recess 13. The detent, pivoted at 15 to the plate 14, is pressed towards the rack by a spring 21 and is formed with ratchet teeth 17. A coin 36 inserted in a vertical shoot 29 forms an abutment for the tail of the detent 16 to hold the nose 18 away from the rack 20 as the drawer is pulled out. The teeth 17 prevent the drawer from being partly pulled out and then returned, as the coin interlocks with the teeth, when the movement of the drawer is reversed. The coin is supported by the side of the plate 14 and drops when the drawer is fully pulled out. The teeth of the rack ensure a full inward movement of the drawer which is completed by a spring 35 pressing a lever 33 against the screw 8. The coin presses aside a weighted pawl 30 which moves back over the coin and prevents it from rising in the shoot 29. A coin inserted in the shoot before the drawer is completely returned is prevented from falling into petition by a lug 27 on the top plate 22. Two drawers may be controlled from a single coin shoot as shown in Fig. 9. A member 39 sliding at right angles to the direction of movement of the drawers engages in one or other of two slots 40, 40<1> in the drawers to lock one drawer, when the other is pulled out.

Title: Polymeric mordanting agents for anionic compounds
IPC: G03C1/835
Filed: 1971-01-11
Abstract: 1381263 Guanidinium keto-imine polymers AGFA-GEVAERT 13 Dec 1971 [11 Jan 1971 10 Sept 1971] 1288/71 and 42381/71 Heading C3P [Also in Division G2] Polymers useful as mordants in photographic compositions comprise units of the formula where R 1  is hydrogen or methyl, A is methylene, optionally substituted by C 1 -C 5  alkyl, n is 0 or 1, R 2  is alkyl and X is an acid radical. They are prepared by condensing aminoguanidine or a salt thereof with polymers containing units of the formula  when the product will also contain unreacted ketone units, or with the corresponding ketone monomer prior to polymerization. In the latter case the condensation is quantitative; the condensation product can be polymerized in situ. The exemplified polymers are all derived from diacetone acrylamide (R 1  = H; A = C(CH 3 ) 2 ; n = 1; R 2  = CH 3 ). A homopolymer of this monomer and copolymers with acrylamide, acrylonitrile, methyl acrylate or N-t.- butylacrylamide are reacted with aminoguanidinium bicarbonate, and the resulting products are recovered in free base form, then dissolved in aqueous acetic acid. In other examples diacetone acrylamide is reacted with varying proportions of the bicarbonate, converted to the acetate form and polymerized. Reference has been directed by the Comptroller to Specification 1,297,324.

Title: Improvements in and relating to a process for the polymerisation of diolefins
IPC: C08F36/04
Filed: 1959-01-19
Abstract: A catalyst for use in polymerizing conjugated diolefines comprises titanium trichloride and a hydrocarbyl magnesium salt. The latter may be an alkyl, cycloalkyl, aryl or alkaryl magnesium chloride, bromide or iodide and is preferably present in minor amount, the mol. ratio of titanium to magnesium being 1.5-5 : 1.  Polymers of diolefines containing at least 80% 1,2-configuration and having a molecular weight of 2500-100,000 and prepared in the presence of the above catalyst are used for coating metal or wood. The polymer is used in a solvent or in solution as prepared and applied by dipping, painting or rolling and is cured at 100-200 DEG  C. for 10-30 minutes.  Cobalt driers may be added in amounts of 1-2% by weight.  Pigments such as titanium dioxide can be added to form enamels.  Metals coated with the polymer have good resistance to hot solder.  The polymers can also be epoxidized with an organic peracid and the products can be cured with amine curing agents in a solvent to form hard, insoluble, infusible coatings.ALSO:Conjugated diolefines are polymerized in the presence of titanium trichloride and a hydrocarbyl magnesium salt in an inert atmosphere and under anhydrous conditions; the polymers are liquids or solids generally of molecular weight of 2500-2,000,000 and having at least 80% 1,2-structure.  The diolefine may be butadiene, isoprene, dimethylbutadiene, piperylene or methyl pentadiene, preferably of at least 10% purity, and may be copolymerized with up to 30% by weight of monomers of styrene, alphamethylstyrene, divinylbenzene, vinylpyridine or 2-methyl-5-vinylpyridine.  The magnesium compound is preferably an alkyl, aryl, alkenyl, cycloalkyl or alkaryl magnesium chloride, bromide or iodide, preferably containing not more than 12 carbon atoms, e.g. phenyl-, cyclohexyl- or butyl-magnesium bromide, tolyl-, dodecyl-, or allyl-magnesium chloride and hexadecyl- or isopropyl-magnesium iodide.  Although either component of the catalyst may be used in excess the mol. ratio of titanium to magnesium is preferably 1.5-5:1.  The total amount of catalyst may be 0.01-1% by weight of monomer.  An ether or hydrocarbon diluent is preferably used, e.g. diethyl-, dibutyl-, diallyl-or diamyl-ether, tetrahydrofuran, dioxane, tetrahydropyrane, benzene, toluene, n-heptane, pentane or octane.  Temperatures of 0-100 DEG  C. can be used and times of 1/2 -10 hours.  The inert atmosphere may be provided by nitrogen, or methane or, if gaseous, the monomer.  The catalyst is destroyed by addition of alcohol or water.  Coatings formed from the polymers can be cured by heating to 100-200 DEG  C. for 10-30 minutes, with or without cobalt driers. The double bonds can be epoxidized by performic, peracetic, perbenzoic or monoperphthalic acid in the presence, if desired, of benzene, toluene or chloroform, at -20 DEG  to 100 DEG  C.  The epoxidized product can be cured to hard, insoluble, infusible coatings with amine curing agents.  The polymers may also be cross-linked with peroxides.

Title: Improvements relating to the operation of lift doors
IPC: B66B13/18
Filed: 1945-01-25
Abstract: 588,020. Door-operating appliances. HALL, Ltd., J. & E., and ELVY, S. T. Jan. 25, 1945, No. 2042. [Class 65 (i)] A lift door biassed to the closed position by means capable of closing it against normal resistance is opened by power-operated means which also acts to control the closing speed. In the arrangement shown in plan in the "dooropen" position, carried on the lift cage, a reversible worm-shaft 2 engages a nut 11 mounted between arms 18 on a carriage 14 which slides on guide-bars 15, 16 and'carries a pivoted arm 13 normally engaging with the nut 11 to prevent rotation thereof; the shaft 2 is driven by an electric motor (not shown) through a belt passing over a pulley. 10, the belt being tensioned by mounting the motor on a spring biassed hinged base. The carriage 14 has slidably mounted in it an arm 24 for engagement with the lift door and, if desired, the shaft door, this arm having at its inner end a roller engaging a cam track 26 whereby it is retracted jn the "door closed" position so that the .door is free for manual operation if the power fails; the outer end 29 of the arm 24, which engages on the left-hand side of a member on the door or doors, is spring-hinged to the arm so that it can be moved to the proper side of the door member if it happens to be on the wrong side, and has a pivoted tip 30 which can yield vertically if the cage is moved with the arm not fully retracted. The closing movement of the door or doors is produced by spring or weight means which is not strong enough to drive the shaft 2 by pushing the nut 11 along, so that the shaft has to be driven by the motor to allow the door or doors to close. A cam 39 carried by the inner end of the arm 24 actuates normallyclosed limit switches, and also closes other switches near the ends of the door movements so that when a door movement is initiated a solenoid 21 is energised to rotate the guidebar 16 through a small angle ; cams 19 on the guide-bar on to which the end of the arm 13 rides at each end of the door movement to free the nut 11 in order to avoid the need for accurate stopping of the motor, are thus lowered to permit the arm 13 to engage the nut for the door-operating movement. A circuit for controlling the motor by means of the liftcontrol switch, so that when the latter is off the doors open and when they close, subject to suitable interlocks with the lift motor circuit, is described and shown. According to the Provisional Specification, the switches controlling the solenoid 21 by movement of the door may be replaced by a time switch.
