Title: Improved process for producing hydrogen and phosphoric acid
IPC: C01B3/06
Filed: 1927-02-24
Abstract: 278,578. Urbain, E. Dec. 7, 1926, [Convention date]. Hydrogen.-The temperature at which the reaction 4P+10H2O= 2 P2O5+10H2 is carried out is lowered below 500‹ C and to about 350‹ C. by carrying it out in the presence of absorptive carbonaceous material, such as charcoal, and of hydrochloric, hydrobromic or hydriodic acids which act as catalysts. Phosphorus vapours are mixed with hydrochloric acid gas and steam and passed over carbonaceous material maintained at about 350‹. Alternatively phosphorus may be first absorbed by the carbonaceous material and then subjected to the action of hydrochloric acid and steam. Phosphoric acid is obtained by washing the carbonaceous material.

Title: Improvements in or relating to sorting, grading or recording apparatus
IPC: B07C5/30
Filed: 1934-02-19
Abstract: 425,721. Weighing-apparatus. BEST, C., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. Feb. 19, 1934, No. 5427. [Class 143] Relates to a weighing-mechanism of the type wherein the weighbeam carries an element adapted to be thrust by a pressure member against members which actuate counting, registering or sorting devices and consists in providing the beam element and the pressure member with sharp deflecting projections, one at least of the co-operating projections being pointed, the object being to avoid actuation of two adjacent counter &c. members by the same operation. As shown, the cigarettes in a hopper 2 are delivered one at a time to a scale pan 4 suspended from a weighbeam 5 as described in Specification 425,722. A flexible arm 6 carried by the weighbeam is thus moved over the lower ends 18-22 of counter-operating levers 13-17 according to the weight (correct, over or under) of the cigarette. A rockable member 23 is then operated by a cam 41 to press the arm 6 against the opposed counteractuating lever and thus actuate the relevant counter 8-12. In order to prevent the arm 6 from operating two counters during the same stroke a series of knife-edges 26-29 are mounted on the rockable member 23 opposite the gaps between the ends 18-22, and the arm 6 is provided with a needle or sharp-edged element, the arrangement being such that upon an actuating movement of the rockable member one of the knife-edges may engage the needle and thrust the arm 6 to one side or the other to ensure its impact with one only of the ends of the levers 13-17. To ensure that the lateral movement of the arm 6 takes place before the arm engages the ends of the levers, a restraining bar is resiliently supported between the arm and the levers. The knife-edges 26-29 are preferably formed as triangular prisms mounted on horizontal slides by means of vertical screwthreaded stems. By rotating the prisms a fresh knife-edge or a fresh portion of a knifeedge may be brought into operation. Sorting by weighing.-The weighed cigarettes may fall out of the scale pan 4 into one of five movable receptacles, the appropriate receptacle being automatically moved to receive the cigarette according to which of the counteroperating levers 13-17 is operated. Specification 261,957, [Class 143], also is referred to.

Title: Improvement in resolution of racemic ª‡-hydroxy-ª‰ú¼ª‰-dimethyl-gamma-butyrolactone
Filed: 1941-04-29
Abstract: 552,705. Resolution of α(-hydroxy-##-dimethyl-γ-butyrolactone. MERCK & CO., Inc. April 29, 1941, No. 5524. Convention date, July 3, 1940. [Class 2 (iii)] α - Hydroxy - ## - dimethyl - y - butyrolactone is resolved into its stereo-isomers by formation of an alkaloidal salt of the racemic αγ-dihydroxy ##-dimethyl butyric acid followed by fractional crystallization. The formation of the alkaloidal salt may be carried out by forming a solution containing equivalent quantities of an alkaloidal salt and a metal salt of the racemic acid, or if desired the sodium salt of the racemic acid may be treated with one-half equivalent of the alkaloid salt to form the insoluble alkaloid salt of one isomer leaving the sodium salt of the other isomer in solution. If desired a solution composed of a preponderance of one stereo-isomer together with an amount of a racemic salt may be crystallized whereby the preponderant stereomer crystallizes. Alkaloids mentioned include quinine, quinidine, cinchonine, cinchonidine, strychnine and brucine. Examples are given of the separation in which (1) quinine sulphate is added to a solution of the barium salt of αγ- dihydroxy-## dimethylbutyric acid and the quinine salt crystallized, and (2) quinine hydrochloride is added to a solution of the sodium salt of the acid and the separation effected.

Patent GB-498564-A (GB)
Title: Improvements in or relating to automatic clutches
IPC: F16D47/00
Filed: 1938-02-22
Abstract: 498,564. Change-speed gearing; friction clutches. HENRIOD, C. E. Feb. 22, 1938, No. 5637. Convention date, Feb. 22, 1937. [Class 80 (ii)] In an automatic clutch of which the driving and driven elements are engaged with one another by centrifugal masses acting against opposing means, the masses are of U-shape with their legs straddling the rotating assembly formed by the elements and at least one ball is interposed between each ball of the U-shaped masses and the adjacent face of the assembly in a groove radially inclined to the axis of rotation of the assembly so that radial movement of the centrifugal masses under increasing centrifugal force causes an engaging movement of the clutch. A driving member comprising a fly-wheel 3 and disc 1 rotates a plate 7 in unison therewith through U-shaped members 10, the legs of which are provided with tapered inclined recesses 15 for balls 14, 16, the members 10 being displaceable under centrifugal force to move radially in apertures 56, 57 in the disc 1 and plate 7 respectively, to draw together the plate and disc, against the action of springs 9, on to friction surfaces 6 on a driven plate 521. The clutch is shown combined with an automatic variable three-speed gear, the plate 52<1> being connected through a sleeve 20 with a low speed-gear train 21, 22 including a freewheel clutch 21<1>. The train wheel 22 drives, through a sleeve 24, a resilient disc 52<2> carrying a plate 25 operatively connected by balls 26, housed similarly to the balls 14, 16, to an annulus 27, itself similarly connected through balls 28 with an annulus 29 turning with the driven shaft 5. As the speed of the shaft 5 increases, a clutch 31 associated with a gear train 23, 23<1>, 22 for the second speed is engaged by the centrifugal action of U-shaped masses 36, mounted on the plate 25 in the same way as the masses 10 on the plate 1, this action bringing together the plate 25 and annulus 27. Further increase in the speed of the shaft 5 closes the disc 29 on to the annulus 27 through the action of similar centrifugal masses 46 on the annulus 27, the annulus 29 being carried by a resilient plate 52<3> to permit its displacement relatively to the shaft 5. Specification 484,198 is referred to. The Specification as open to inspection under Sect. 91 describes a construction in which the disc 1, Fig. 1 (Cancelled), carries studs 8 which project through the plate 7 and on each stud is mounted a disc 12 opposite a similar disc 11 on the plate 1. Recesses having inclined bottoms are formed in the inner surfaces of the discs to house the balls 14, 16 which support a centrifugal mass 10, the centrifugal force tending to separate the discs. The disc 7 is rotated solely by the action of the balls 14, 16 and the driving torque assists the separation of the discs. This separation moves the plate 1 and disc 7 towards one another and into engagement with friction surfaces 6 on both sides of a disc 4 corresponding to the plate 52<1>, Fig. 1. This subject-matter does not appear in the Specification as accepted.
Patent GB-684380-A (GB)
Title: Improvements in mechanism for steering a tractor
IPC: B62D15/00
Filed: 1951-03-09
Abstract: 684,380. Steering motor vehicles. DUFOUR, L. March 9, 1951 [March 29, 1950], No. 5718/51. Classes 79 (ii) and 79 (v) A tractor is steered from a hand steering wheel which actuates a known steering linkage to cause deviation of the front wheel or wheels and which also operates, through a resilient connection, one or other of the rear wheel brakes. The arrangement is such that preliminary movement of the steering wheel causes deviation of the front wheels only, continued movement thereto also applies the inside rear brake and further movement thereof moves the front wheels only whilst the resilient brake connection accommodates the further movement of the brake operating members. As shown in Figs. 1 and 3, 'the steering wheel 4 actuates through worm and worm wheel 5, 6 a cross shaft 7 to which is keyed a drop arm 13 connected to drag link 14 and a known steering linkage 15. To the ends of cross shaft 7 are keyed brake actuating levers 8, 8<SP>1</SP>. Lever 8 abuts against one end of a compression spring 10 whose other end is fixed to rod 9; rod 9 passes freely through lever 8 and brake lever 11, and has an abutment 16 which can engage the end of brake lever 11. Upon actuation of the steering wheel and hence rotation of lever 8, preliminary movement. merely takes up the lost motion between stop 16 and brake lever 11. Further movement applies the brake to lock the inside wheel, whereas final movement merely compresses the spring 10 until the front wheels reach full lock, the brake being left on. To achieve this result, the spring 10 is made stronger than the springs within the brakes. The other brake is actuated similarly by lever 8<SP>1</SP>. In a modification, Fig. 8, the lost motion effect in the brake operating mechanism is obtained differently. Each lever 8 is pivoted freely on the cross shaft 7 and is moved by a curved finger 18 which is keyed to the shaft 7 and whose outer end engages the lever 8 after a certain amount of free movement. With this arrangement there is no lost motion connection between the rod 9 and brake lever 11. In a further modification, Figs. 11 and 12, the steering wheel 20 actuates the front wheels as above, but the steering shaft 21 drives through gears 24, 25 a secondary shaft 26 to which is keyed a finger 27 and on which are freely mounted two brakeactuating levers 28, 28<SP>1</SP> which normally rest against stops 29, 29'. On turning the steering wheel the front wheels only are affected until the finger 27 abuts against one of the levers 28, 28<SP>1</SP>. Further movement applies the appropriate brake and further movement still brings the front wheels to full lock and compresses the appropriate spring 10.
