Abstract: 556,451. Controlling motor-propelled invalid carriages. GREEVES, O. B., and COBB, D. PRESTON-. June 13, 1942, No. 8113. [Classes 79 (iii) and 79 (v)] [Also in Group XXIV] In an invalid carriage or like vehicle a controlling hand-lever 21 mounted on a vertical shaft 18 moves in a horizontal plane to steer the front wheel 11 and moves in a vertical plane about a pivot 20 to control the change-speed gear or other part. Other controlling members are also mounted on the lever 21 such as a twist grip 27 for controlling the throttle by a cable 28, a clutch-operating lever 29 provided with a pawl catch 30, a brake lever 31, a control for the engine compression-release valve, a horn-button 34 and a switch 35 for the direction indicator 36. The lever 21 is connected by a ball-jointed link 23 to the gear lever 26; the latter may be of the kind in which the gear in use corresponds to the incl:nation of this lever and therefore of the lever 21 also,but preferably the gear-change mechanism is of the kind in which the gear lever returns automatically to its normal position after each change of gear, the lever being moved downwards (say) to engage the next higher gear ratio and upwards to "change-down." Means may be provided for preventing the gear from being changed unless the clutch is first disengaged. In the construction shown in Figs. 1 and 2 the front wheel 11 is steered by the lever 21 through an arm 17 on the shaft 18, a link 16, and an arm. 15 on the front fork 14. The vehicle has two rear wheels 12 one of which is driven through the change-speed gear by an engine 13 located in front of it. A second brake is actuated by a lever 38, Fig. 4, provided with an arm rest 37 and normally held in the "off" position by a spring 40, the brake being applied by pressure of the arm on the rest. When the vehicle is left unattended this brake may be held on by means of a rack and pawl 43, the latter being normally held out of action by a loop 42. In the gear-changing modification shown in Fig. 5 the clutch is automatically disengaged each time the gear is changed, the gear lever 26 being located between two levers 47, 48 connected respectively to the wire 50 and the casing 51 of the Bowden cable controlling the clutch, so that each time the gear lever 26 is moved whether up or down to change the gear the clutch is disengaged.

Title: Improvements in or relating to the manufacture of articles of rubber-like material
IPC: C08L21/02
Filed: 1944-05-04
Abstract: Articles of rubber-like material are prepared by directly depositing in the desired shape the solids of an aqueous dispersion of a copolymer of butadiene and styrene containing a polyterpene hydrocarbon resin such as those known under the name of "Nypene" and "Piccolyte," and then drying and vulcanizing the solids so deposited. The articles may be directly deposited either onto a former by dipping or spraying or by spreading on a blanket in the case of sheet material.  In an example, 75 parts of butadiene and 25 parts of styrene are emulsion copolymerized in the presence of 5 parts of soap and the emulsion creamed by the addition of ammonium alginate solution followed by potassium hydroxide solution.  After standing, a vulcanizing paste containing sulphur, zinc oxide, zinc mercaptobenzothiazole and dibutyldithiocarbamate, and dispersing agents in water, is added to the cream, and the whole mixed with a dispersion obtained by treating a solution of 100 parts of the polyterpene in 100 parts of naphtha containing 10 parts of oleic acid, with a solution of 10 parts of 25 per cent dimethylaniline in 180 parts of water, the mixture then being spread and vulcanized.  In a second example, methyl isobutyl ketone is used as the solvent for the polyterpene. The resultant improvements in tensile strength and ultimate elongation is compared with the results obtained by similar mixes containing natural rubber.ALSO:Articles of rubber-like material are prepared by directly depositing in the desired shape the solids of an aqueous dispersion of a copolymer of butadiene and styrene containing a polyterpene hydrocarbon resin, such as those known under the name of "Nypene" and "Piccolyte," and then drying and vulcanising the solids so deposited.
