Title: Differential drive apparatus
IPC: D21F7/02
Filed: 1957-09-17
Abstract: 814,701. Drive of paper-making machines. BLACK-CLAWSON CO. Sept. 17, 1957 [Sept. 17, 1956], No. 29239/57. Class 96. [Also in Group XXIV] The shaft 80 of the calender or drier section of a paper-making machine is maintained at a constant speed differential with respect to a main driving shaft 15 of the machine by means of an epicyclic train comprising a driving sun 60 adapted to be coupled to the shaft 15 through bevel gearing 30, 32, pneumatically operated clutch 40, 42 and shaft 50, a driven sun 77 on shaft 80 and planets 67, 68 carried by a cage 72. The cage 72 is adapted to be driven in either direction by a reversible hydraulic motor 85 to vary the speed differential required by variation of the output of a reversible displacement pump which may be separately driven or driven off the main shaft 15. Changes in the speed differential between shafts 15 and 80 is sensed by changes in pressure between a tachometer pump 95 geared to shaft 15 and a feedback tachometer motor 90 driven thereby and geared to the cage 72. Such changes act to regulate the output of the pump supplying motor 85 so that the cage is driven faster or slower to compensate for any speed changes. The output of the tachometer pump 95 is variable by a control 97 operated by a reversible electric motor 98 to provide a variable reference pressure corresponding to the desired speed differential required between shafts 15 and 80. The gearing maintains the speed differential of a section over a main drive shaft and/or over an adjacent section to provide the necessary " draw " which can be regulated by adjustment of the tachometer pump 95. Also, slack in the web, following a breakage therein, for example, can be quickly taken up by operating a valve shortcircuiting the pump 95 to drop the output pressure thereof and thereby increase the output to pump 85 to drive the cage 72 at an increased speed until the slack is taken up. The gearing may also be utilized for " inching " forwards or in reverse by releasing the clutch 40, 42, applying a pneumatic brake 53, 55 to the shaft 50 and sun 60 and operating valves to supply pressure fluid in one direction or the other to motor 85 to drive the cage 72 and shaft 80 at a slow speed.

Title: Compound integrating meter for measuring quantities of gas delivered
Inventor: STICH EDWARD OSWALD
IPC: G01F1/36
Filed: 1952-11-21
Abstract: 716,474. Gas meters. BRITISH OXYGEN CO., Ltd. Oct. 9, 1953 [Nov. 21, 1952], No. 29467/52. Class 54 A compound integrating gas meter comprises high and low range flow tubes 10, 11, provided with orifice plates 12, 13 and separate indicating and integrating meters 19, 22, a tandem valve 32 to simultaneously close one tube and open the other, and electromagnetic means for operating the valve whenever the flow crosses from one range to the other. The pointers of both meters are provided with electrical contacts which cooperate with contacts at the maximum and minimum readings of the low range and high range meters respectively. The minimum contacts on the high range meter act through a relay to energize an electromagnet 33 and hence lift the valve 32 so that the gas flow passes through the low range tube only until it reaches the maximum value of the low range meter when the contacts thereon close to reverse the relay, de-energize the electromagnet 33 and hence permit the valve 32 to drop so that gas passes through the high range tube only. To prevent hunting, an overlap of about 2 per cent is provided between the two ranges, a zero contact on the low range meter arranged in series with the minimum contacts of the high range meter prevents both meters from energizing the relay simultaneously. The electromagnet is supplied by a rectifier from an A.C. source. In order to check that the set pressure at which the instrument is required to function has been maintained throughout its operation, a pressure gauge 41 is mounted on the high range meter 19.

Filed: 1938-10-12
Abstract: 519,277. Sterol iodides. HELFERICH, B. Oct. 12, 1938, No. 29604. Convention date. Oct. 12, 1937. Samples furnished. [Class 2 (iii)] Iodo derivatives of steroid components are prepared by the treatment of hydroxy steroid compounds or enols of steroids in the form of their organic sulphonic acid esters with sodium iodide according to the equation R.SO<2>.O.St. + Na I =St.I + R.SO2.O Na where R indicates an organic residue such as alkyl or aryl and St. indicates a steroid residue. The reaction takes place preferably in organic solvents such as acetone, and at elevated temperatures such as 50‹-130‹ C. The sulphonic acid salt which is formed in the reaction can be employed again for the manufacture of new esters such as by way of the sulphonic acid chloride. In examples (1) cholesterol is treated With methane sulphonic acid chloride in pyridine solution and the methane sulphonic acid ester of cholesterol so produced is treated with anhydrous sodium iodide in acetone at about 60‹ C. The reaction products crystallise, and the cholesteryl iodide is separated from sodium methyl sulphonate by washing with water. (2) p-toluene sulphonic acid ester of cholesterol is heated with sodium iodide in acetone at 60‹C. to give cholesteryl iodide. (3), Ergosterol is heated in pyridine with methane sulphonic acid to give methane sulphonyl ergosterol which is then heated with anhydroussodium iodide in acetone at 60‹- 65‹ C. for 30 hours. The sodium methyl sulphonate crystallises on cooling. This is filtered, the acetone evaporated, and the ergosteryl iodide extracted with ether. Samples have been furnished under Sect. 2 (5) of (1) Sitosterol iodide prepared from methane sulphonyl-sitosterol (which itself is prepared from methane sulphonic acid chloride as' described in example (1) ) by the action of sodium iodide in boiling methanol vapour. (2) Stigmasteryl iodide prepared from methane sulphonyl stigmasterol in the same manner as the cholesterol compound.

Filed: 1926-11-30
Abstract: 280,720. Clark, D'A. M., (Bendix Brake Co.). Nov. 30, 1926. Shoes acting on drums; compensating for wear.-In an internal expanding brake mechanism for vehicles of the kind in which the clearance of one or more of the brake shoes is determined by means of a self-adjusting stop co-operating with a frictional clamping-device, an angularly movable forked blade 52 mounted on the barking plate 12 is arranged to embrace a part movable with one or more of the brake shoes, e.g. the pivot pin 20 between two shoes 14, 16, one arm 50 of the fork being engaged by the part 20 when the brake is applied and the other arm 50 being engaged, after a short lost motion, when the brake is released. In the construction shown, the stop or fork 52 is pivoted on a stem 54, Fig. 4, and frictionally clamped to the plate 12 by a nut 56. When the brake is applied the pin 20 engages one arm of the fork and moves it forwardly until the full braking pressure is exerted; when the brake. is released, the pin 20, after a short lost motion, engages the opposite arm of the fork and is held thereby, as the return springs 26, 30 are unable to overcome the frictional resistance provided by the nut 56. The space between the arms 50 exceeds the diameter of the pin 20 so that the amount of lost motion permitted determines the clearance of the shoe 16 in the released position. In order to allow the operating cam 28 automatically to centre itself, the cam spindle passes through a shiftable bracket 36, Fig. 2, secured to the plate 12 by two bolts 39, 42, one, 39, of which is fixed to the plate 12 and passes through an enlarged hole 39a in the bracket 36, while the other, 42, is fixed to the bracket 36 and passes through an elongated slot 44 in the plate 12.
