Filed: 1974-03-26
Abstract: 1418243 Fuel cell batteries SIEMENS AG 26 March 1974 [30 March 1973] 13456/74 Addition to 1302814 Heading H1B The batteries disclosed in the parent Specification 1,302,814 are modified in respect of the asbestos diaphragms to prevent shear forces acting thereon when the battery is in operation and thus minimize damage to the diaphragms. In the operating condition, the pressure in the gas compartment on one side of the diaphragm is greater than the pressure in the electrolyte compartment on the other side of the diaphragm and if the electrodes in the respective compartments do not press against the entire surface of the diaphragm exposed to the compartments but leave gaps at the edge due to manufacturing tolerances, shear forces are generated. Fig. 10 shows a cross-section through a cell having an asbestos diaphragm 100 pressed on one side by an oxidant electrode 105 in a gas chamber and on the other side by an electrode 104 in an electrolyte chamber, the electrolyte including fuel dissolved therein. The diaphragm 100 comprises three layers 101, 102, 103 bonded together so that the peripheral zone is thicker than the central portion which separates the compartments. In accordance with the invention the width 106 of gasket 102 is less than the width 107 of gasket 103 and the electrode 104 extends beyond the edge 108 of the gas compartment. The detail of Fig. 10 relates to an oxygen-hydrazine battery described with reference to Figs. 1-4 (not shown). The invention may also be applied to an oxygen-hydrogen battery described with reference to Figs. 5-9 (not shown).

IPC: C08B5/10
Abstract: 136,141. Carlsson, O., and Thall, E. Dec. 6, 1918, [Convention date]. Cellulose nitrate solutions; cellulose carboxylate solutions.-The viscosity of solutions of nitrocellulose, celluloid, &c. in the usual solvents, such as ether-acohol, amyl or ethyl acetate, and acetone, is permanently reduced by heating the solutions, while preventing the escape of solvent, to a temperature between 60‹ C. and the temperature at which the solution becomes brown in colour owing to the nitrous products arising from the decomposition of the ester. The temperature to which the solution is heated and the duration of the heating are correlated; the longer the heating and the higher the temperature, the more is the viscosity reduced. The Specification as open to inspection under Sect. 91 (3) (a) includes also the application of the process to solutions of cellulose acetate and other cellulose esters. This subject-matter does not appear in the Specification as accepted.

Filed: 1926-06-03
Abstract: 278,050. Macbeth, C. June 3, 1926. Balling-machines.-In a machine for winding golf-ball cores and in like machines the pressure which locates the work on its driving devices is periodically automatically reduced to enable the work to change its axis of rotation. The ball core 1 is supported on a back roller 2 and a shuttle roller 3, Fig. 1, and is held by pressing rollers 9<A>, 9<B> loose on pins 8, Fig. 3, carried on an arm 9 pivoted at 10 and weighted at 13, the rollers remaining tangential to the surface of the core as it is wound. The pressure of the rollers 9A, 9s is automatically relieved at intervals by a cam 19, Fig. 6, the spindle 17 of which is driven by gearing and a ratchet-and-pawl 35, 35A from the back roller 2. The cam 19 gradually lifts a slide 20 carrying a lever 24 weighted at 26 and having jaws 28 bearing under a slide 30 connected by the link 12 to the arm 9. On the slide 20 being released by the cam 19 it drops into contact with an adjustable bush 21 and the inertia of the weight 26 momentarily raises the slide 30 thereby reducing the pressure of the rollers 9A, 9B. In a modification, the pressing weight 13A, Fig. 8, is suspended from a beam 98 supported by links 96, 109 from the arm 9 and rocker-arm 99, the cam 100 allowing the system to drop periodically on to a stop 103 to relieve the pressure of the rollers 7. The roller 3 is rotated and reciprocated by means of the inclined pinion 4B, Fig. 2, having a ring 4c, cooperating with a pinion 4A and groove 4D on the spindle 4.
