Title: Improvements in acoustic signal producing devices for toys
IPC: A63H17/32
Filed: 1945-09-10
Abstract: 598,788. Sound-producing toys. HUARD, G. G., and ROGER, R. J. E. Sept. 10, 1945, No. 23278. Convention date, April 6. [Class 132 (iii)] An acoustic signal device for mechanical toys moving on a plane surface comprises a rapidly rotating component which drives a clapper normally rotating at a distance from a co-operating gong and a slowly rotating component which acts at each rotation (by one or several cams) on the gong or on the clapper support to cause the clapper to strike the gong for an instant. Fixed on to the winding spindle 1, Fig. 1, of the driving spring 2 of the clockwork motor is a large cogged plate 4 which, by means of pinions 5, 6, 7, 8 drives the axle 3 of the rolling wheels of the vehicle. A further series of step-up gears 13, 14, 15 drives the rotating clapper 11, which may act as a governor, and comprises two parallel bars 11<1> and 11", Fig. 3 A washer 16 is placed between the bars at one end so that it can play freely on its axis and serves as a bob to unbalance the clapper. The gong 17 is borne freely on the casing of the toy by a plate 18 ending in a hook 24 which, at each rotation of the wheel 4 is contacted by the cam 25 and is pulled along by it from the position 17<1> to 17, in which position it is struck by the washer 16 on the clapper 11. As soon as the cam 25 has escaped from the hook 24 a blade spring 26, fixed by one end 27 to the bottom of the casing and projecting through a hole 28 in the plate 18 returns the gong to the position of rest 17<1>. An alternative construction, in which the clapper support is moved by a camshaped projection on the wheel 4 to strike a stationary gong is also described. If it is not necessary to employ an unbalanced clapper, it may be balanced by fixing a washer at each end. Several cams may be placed on the wheel 4 to give a corresponding number of signals. The device may be incorporated in a toy driven by any motor other than clockwork, for instance an electric motor, or the device may also be driven by a separate motor distinct from that controlling the vehicle.

Title: Speed responsive switch
IPC: H01H35/10
Filed: 1953-08-24
Abstract: 734,822. Actuation of switches. GAYLORD PRODUCTS, Inc. Aug. 24, 1953 [Sept. 5, 1952], No. 23306/53. Class 38 (5). A speed-responsive switch, which may be arranged between the speedometer of a vehicle and its driving cable, comprises a contact blade 42 pivotally suspended from a rotary member 25 and dipping into a non-conductive liquid 49, the arrangement being such that the blade 42 engages a fixed contact 45 or a pool of mercury lying just above it when the member 25 is stationary, but moves upwards out of engagement with it when the member 25 rotates about its axis 23 due to the friction between the blade and the liquid 49. The member 25 is bevelled at 25 and driven either frictionally or otherwise by a bevelled member 28 on the rotary shaft 12 which is connected to the driving cable of the speedometer.

Patent GB-751573-A (GB)
Title: A polyene dialdehyde and process for the manufacture thereof
Filed: 1954-08-12
Abstract: The invention comprises 2,6,11,15-tetramethyl - hexadecahexen - (2,4,6,10,12,14) - ine-(8) - dial - (1,16) and a process for its preparation by acetalizing 4,9-dimethyl-dodecatetraen-(2,4,8,10) - ine - (6) - dial - (1,12), condensing the diacetal so obtained with a propenyl ether in the presence of an acidic condensing agent and treating the resulting 3,14-dietherified 2,6,11,15 - tetramethyl - hexadecatetraen-(4,6,10,12) - ine - (8) - diacetal - (1,16) with an acid agent to effect hydrolysis of the acetal groups and elimination of alcohol from between positions 2 and 3, and 14 and 15.  Specified acid condensing agents are boron trifluoride-ether complex, zinc chloride, aluminium chloride, and the tetrachlorides of titanium and tin, whilst the acid agent used for the hydrolysis of the acetal groups is a water-soluble non-volatile organic or inorganic acid, e.g. p-toluene sulphonic, acetic, propionic, sulphuric or phosphoric acids, or a water-soluble salt having an acid reaction, e.g. zinc chloride or sodium hydrogen sulphate.  In an example 4,9-dimethyl-dodecatetraen - (2,4,8,10) - ine - (6) - dial (1,12) in ethyl orthoformate is heated with ethanolic ammonium nitrate to yield the corresponding di(diethyl acetal)-(1,12), which is treated with ethyl propenyl ether and boron trifluoride-ether complex to produce 3,14-diethoxy-2,6,11, 15 - tetramethyl - hexadecatetraen - (4,6,10,12)-ine - (8) - di(diethyl acetal) - (1,16).  Hydrolysis with phosphoric acid in aqueous dioxan containing a trace of hydroquinone yields 2,6,11,15 - tetramethyl - hexadecahexen-(2,4,6,10,12,14)-ine-(8)-dial-(1,16).  The Specification also refers to the formation of dehydro-methyl bixin, dehydro-crocetin and dehydro-bixin dialdehyde from the novel compound of the invention.  4,9 - Dimethyl - dodecatetraen - (2,4,8,10) - ine-(6) - dial - (1,12) is prepared by acetalizing 2,7 - dimethyl - octadien - (2,6) - ine - (4) - dial-(1,8) with ethyl-ortho-formate in the presence of ammonium nitrate, condensing the product with ethyl vinyl ether and hydrolysing the 3,10-dietherified - 4,9 - dimethyl - dodecadien - (4,8)-ine - (6) - diacetal - (1,12) with aqueous phosphoric acid.

Title: Apparatus for drying webs
IPC: B41F23/04
Filed: 1947-08-25
Abstract: 636,767. Drying and cooling paper. OFFEN, B. Aug. 25, 1947, No. 23442. [Class 96] [Also in Groups XIII and XVI] In a two-stage drying machine for textile or paper webs the drying burners are automatically deflected and cold air introduced on interruption of the web feed to permit instantaneous stopping without scorching. The web 5, after passing under gas burners 12 is subjected to hot air blasts through nozzles 33. Automatic means actuated by stoppage of the web-producing or processing machine energize devices, such as pneumatic rams 16, 23, to move the burners away from the web (and optionally to stop the gas supply to the burners) and also start a fan 54 delivering cold air through pipe 53 to the first drying stage 3 and open dampers 39, thus permitting cool air to flow into the second stage 4. Shield members in the form of steam- or water-cooled pipes may be interposed between the burners and web when the former are deflected. At the exit the web passes over a chilling roller 11 and past an air-blast from pipe 51 to prevent condensation.

Title: Improvements in and relating to the production of hydraulic cement
IPC: C04B7/02
Filed: 1931-08-26
Abstract: A hydraulic cement comprises a clinker derived from burning a mixture of calcareous, siliceous and argillaceous material (i.e. of the type of Portland cement) and ground to British Portland cement fineness standard in admixture with calcium carbonate ground to a fineness such as to leave no appreciable residue on a 76 mesh sieve, and preferably of a fineness not greater than that of the cement.  The amount of calcium carbonate is selected so as to be about 7 1/2 or 8 times that of the calcium oxide set free during hydration of the clinker, although in certain cases, e.g. for plastering, the amount may be increased, the excess carbonate then acting as aggregate.  To delay setting retarders such as potassium dichromate, boric acid, borax, or sodium or potassium or calcium sulphate may be added to the mixture. Aggregate such as sand, small stones, fibre, &c. may be added.  In examples are specified: 100 parts of clinker containing 12 per cent of free lime and 88 parts of calcium carbonate, 100 parts ground Portland cement clinker and 62.4 parts of calcium carbonate, 100 parts clinker containing 10 per cent of free lime and 80 parts of calcium carbonate; 100 parts clinker containing 6 per cent of free lime and 44 parts calcium carbonate; and for plastering a mixture including about 85 per cent of the total of calcium carbonate.
