Title: Improvements in or relating to change speed gears
IPC: F16H3/08
Filed: 1932-10-13
Abstract: 392,818. Change-speed gearing; oneway clutches. JOUAN, F., 80, Rue St. Lazare, Paris. Oct..13, 1932, No. 28596. Convention date, Oct. 13, 1931. [Class 80 (ii).] In change-speed gearing for vehicles comprising aligned driving and driven shafts 2, 4, Fig. 1, and a parallel countershaft 3 which drives a gear 14 loose on the shaft 4, there is housed within the gear 14 a one-way clutch 62 which overruns on direct drive as well as on other speeds. The countershaft forward drives are effected by clutching loose gears 23, 24, 25 alternatively to the shaft 2 by dog clutches 36, 37, 38 respectively. To effect the direct drive, a dog clutch 39 splined on the shaft 2 is engaged with recesses 11 on the face of the gear 14, which is thus driven in direct drive as well as in countershaft drives. Between theinside of the gear 14 and a hub 10 fast on the shaft 4 is a one-way roller clutch 62 adapted to be locked by sliding a dog sleeve 40 splined on a sleeve 16 of the gear 14 into engagement with dogs 42 fast on the shaft 4. In changing speed, the accelerator is released, whereupon the shaft 2 slows down and the shaft 4 is automatically disengaged from the gearing. The one-way clutch 62 is engaged by an auxiliary one-way clutch 61. The main grip rollers 62, Fig. 2, are in slots 60, Fig. 8, in a cage 57 having an end flange with recesses 58 in which are balls 61. When the drive picks up, the balls 61 first jam, and, by means of the cage 57, carry the main rollers 62 of the clutch into gripping position. A modification is described in which on direct drive the toothed gearing is at rest. In this form the dog clutch 39, instead of engaging the toothed gear 14, engages a ring member 75, Fig. 5, within it which surrounds the one-way clutch 62 and is adapted to be unclutched from the gear 14 as the dogs 39 engage that gear.

Title: Improvements in or relating to apparatus for transporting piles of articles
IPC: B66C1/16
Filed: 1934-10-05
Abstract: 445,204. Lifting-cradles for articles in stack formation. WALKER, J. H., 21, Shooters Hill Road, Blackheath, London. Oct. 5, 1934, Nos. 28600/34 and 19227/35. [Class 78 (iv)] A cradle or sling for lifting a stack of articles formed with tunnels at the base, including the articles forming the side walls of the tunnels, comprises a series of separate bars inserted one in each tunnel and lifting- means adapted to engage and lift all the bars simultaneously. In the application to the lifting and setting- down of stacks of bricks without disturbing the formation of the stack and without necessitating the retention of any part of the cradle at the point of deposit, loose bars 3, Fig. 1, with hooked ends are pushed through the tunnels, while longitudinal bars 4, Fig. 16, engage the projecting hooked ends so that all can be lifted simultaneously by the sling or cradle shown in Fig. 16 and set down in a new position, after which the bars 3 can be withdrawn for further use. In one construction of cradle the loose bars are received in holes or bayonet-slots in side plates pivoted to a sheet-metal back plate. Various means are described for lifting the bricks forming the side walls of the tunnels along with the rest of the stock. Fig. 3 shows bent wire loops 6 linking the bricks 1 to the bricks 5<1> of the second layer. In another construction the bricks 1 are supported in the channels of a sheet-metal framing. Numerous forms are also described in which the lifting-bars 3 are made to expand sideways in the tunnels and grip the bricks of the bottom layer. For example, the forcing down of the hinge 9, Fig. 6, when the stack is lifted, causes pads 10 of resilient material to be forced outward into engagement with the bricks. In other constructions the gripping-effect is obtained by the relative movement of two linked bars of the parallel-ruler type. Fig. 10 shows a further construction in which a spring 16 is deformed to an elliptical section to give a side grip. In another example pads of rubber are deformed laterally by squeezing them at the ends. The bars 3 may also be formed as wedges to expand other wedges arranged in the tunnels on opposite sides of them. Fig. 17 shows a loose cover comprising four walls hinged at 39 on opposite corners and furnished at the other corners with mating flanges 40 for receiving locks or securing bolts. Specification 395,800 is referred to.

Title: Enteric gelatin capsule shell or envelope
IPC: A61K9/48
Filed: 1945-11-05
Abstract: Cellulose acetate hydrogen phthalate containing 5-25 per cent weight of free carboxyl is prepared by dissolving phthalic anhydride in pyridine, adding cellulose acetate containing 33 per cent acetyl and heating on a steam bath for 14-18 hours.  The reaction mixture is diluted with acetone, poured into 5 per cent hydrochloric acid and the resultant precipitate washed and dried. In the form of its water-soluble salts it may be incorporated in gelatin capsules which, after subsequent tanning in 1 per cent aqueous formaldehyde, to render them resistant to dissolution in the stomach, are thereby capable of rapid disintegration in the intestinal secretions.  The sodium, potassium, ammonium and lithium salts and salts of organic amines such as diethanolamine, ethylene diamine, diethylene triamine and triethylene tetramine are specified.ALSO:A medicinal capsule shell consists of a tanned gelatin envelope which contains in dispersed admixture with the gelatin, particles of a material resistant to dissolution in the stomach but capable of dissolving in the intestinal secretions.  Such materials are the water-soluble salts of cellulose acetate hydrogen phthalate containing 5-25 per cent free carboxyl and they may be used in the proportion of 5-10 per cent wt. of the shell.  Examples are the sodium, potassium, ammonium and lithium salts, and the salts of organic amides such as diethanolamine, ethylene diamine, diethylene triamine and triethylene tetramine.  In an example finely ground cellulose acetate hydrogen phthalate is mixed with sufficient sodium bicarbonate to neutralize the phthalate and the mixture dissolved in water Gelatin is soaked in aqueous glycerin, the phthalate mixture added and the product maintained at 600 DEG C. The phthalate should dissolve and the pH of the solution should not exceed 7-7.5.  This solution is suitable for preparing capsules which are subsequently tanned as, for example, by immersion in 1 per cent aqueous formaldehyde solution followed by washing and drying.
