Abstract: 636,698. Roller skates. WAGNER, F. J. Aug. 8, 1947, No. 21949. [Class 132 (i)] A roller skate suitable for figure skating comprises a shoe support mounted on a bar in turn mounted on a pair of castings each carrying an axle for a pair of wheels and each connected to the bar by two pins, namely a first pin fixed to the casting and connected by a universal joint to the bar, and a  second pin fixed to the bar and engaging the casting through resilient means interposed between the second pin and the casting, the arrangement being such that the casting is free to rock about the universal joint against a restoring force provided by the resilient means. In Figs. 1-4, the roller skate comprises heel plate 1. and front plate 2 mounted on bar 3 which in turn is mounted on a pair of castings 11. The rear casting 11 carries axle 7 and wheels 9, while the front casting 11 carries axle 8 and wheels 10.

Patent GB-219937-A (GB)
Abstract: 219,937. Felt & Tarrant Manufacturing Co., (Assignees of Turck, J. A. V.). July 31, 1923, [Convention date]. Zeroizing mechanism.-In machines in which the resetting to zero of the numeral wheels of the totalizer is effected by springs during the detraining of the transmission pinions, locking levers are provided for preventing such resetting movement except during a zeroizing operation. The invention is shown applied to the machine described in Specification 219,923, the totalizer and zeroizing mechanism being mounted on a laterally movable carriage in which is also arranged a revolutions-counting mechanism adapted to be zeroized concurrently with the numeral wheels of the totalizer. The differentialactuating sectors 33, controlled by the keys as described in the above-mentioned Specification, engage pinions 111 associated with the usual ratchet mechanism 112, 113 and transmission pinions 114. Each pinion 114 meshes with a gear 131 which is associated, as described in Specification 219,938, with a gear 130 that transmits the movement of the pinion 114, through gearing 127, 128, to the totalizer numeral wheels 124. The gear 130 is secured to one end of the transfer-effecting spring 147 the other end of which is attached to the shaft 135 of the next higher pair of epicyclic pinions 141, 142, as described in the last-mentioned Specification. The carriage is pivotally and slidably mounted on a rod 120 and is adapted to be held in its set position by a rocking arm 123 engaging a corresponding notch in a fixed bar 121. To prevent the return to zero of the numeral wheel, by the unwinding of the springs 147 each time the carriage is raised for a lateral shaft, spring- controlled locking levers 163 are provided which have detents 165 adapted to move into engagement with the gears 130 when the arms 166 thereof are freed from engagement with the ledge of the bar 121. The zeroizing of the numeral wheels is effected when the carriage is raised by rotating a shaft 184 which by means of notches therein causes spring-controlled release levers 187 to be rocked and by their free ends effect the disengagement of the locking levers 163 so as to permit the springs 147 to return the numeral wheels backwardly to zero position; the wheels are arrested in this position by zero stops 190 coacting with detents on the corresponding stop levers 192. At the same time the revolutionscounting wheels 168 are reset by means of the stop levers 192 the extensions 193 of which are adapted to engage projections on the tail ends of the retaining pawls 173 to free them from the ratchet wheels 172 to permit the numeral wheels to return to zero under the action of the springs 175 attached at one end to the numeral wheels and at the other end to the frame. The wheels are arrested in the zero position by a stop pin 194<b> on the ratchet wheel 172 contacting with a loose arm 194<a> adapted to be arrested by a fixed stop 195. Specifications 13094/04, 26772/12, and 16036/13 are also referred to.

Abstract: 220,676. Nielsen, H., and Laing, B. March 21, 1923. Hydrogen.-In the manufacture of gas bv the distillation of carbonaceous material in which water gas is passed unburnt through the retorts during the coking the blow-gas produced in the water-gas generator is used for reduction of the iron oxide in the iron-steam process for the manufacture of hydrogen, which is then added to the distillation gases. Residual reducing gas issuing from the reduction apparatus is admitted together with secondary air to chequer-work chambers and the heat generated is used to superheat the steam before passage over the reduced iron. The carbonaceous material used in the water-gas generator is that resulting from the coking process.

Abstract: 251,229. Soc. Chimique des Usines du Rhone. April 27, 1925, [Convention date]. Phosphoric esters of carbohydrates and polyvalent alcohols are prepared by treating the latter with phosphoric anhydride in the presence of an anhydrous tertiary base, such as pyridine and its homologues, or mixtures thereof ; an inert diluent may also be present. The products are isolated in the form of their calcium salts. According to the examples, a suspension of phosphoric anhydride in pyridine is added to pyridine solution of glucose or laevulose and the mixture heated; after distilling off the excess of pyridine, water is added and the solution neutralized with calcium carbonate or hydroxide; after filtration and concentration in vacuo, the calcium glucose or laevulose monophosphate is precipitated with alcohol. In the same way are prepared calcium saccharose monophosphate and calcium lactose monophosphate, whilst by using the requisite proportions of' phosphoric anhydride, calcium mannite mono- and di-phosphates are similarly obtained.
