Abstract: 361,333. Gearing for stopping machinery. FORD MOTOR CO., Ltd., 88, Regent Street, London. May 12, 1930, No. 14602. Convention date, May 25, 1929. [Class 80 (ii).] An automatic machine for electrically welding spokes to a hub or rim is provided with means for stopping it when all the spokes are welded or at the will of the operator. At the moment when the welding current has been cut off after welding the last spoke and the electrodes withdrawn a projection 168, Fig. 8, fixed on a gear 160 on the driven shaft 24, comes exactly opposite the end of a spring- mounted slide 162 carried by a gear 161 rotated nine or eleven times by ten revolutions of the gear 160. The other end of the slide 162 strikes a lever 171, Fig. 7, and, acting through link 173, lever 174, link and lever 183, raises the detent 49 to allow a spring 47 to withdraw the clutch and stop the machine. If desired, the slide 162 may be arranged so that either end can be engaged by the projection 168, the gear 160 in this case making 20 revolutions to 9 or 11 of the gear 161. The lever 174 has an arm 176, engaged by a cam 177 on the shaft 181, which returns it and the detent 49 to its original position when the machine is restarted, this action also moving a sleeve 195 against the pressure of a spring 197 to the left where it is held by a detent 204. If it is desired to stop the machine manually the detent 204 is raised by pressing the button 198 and, when the cam 177 reaches the position shown, which corresponds to the work-released position, the spring 197 moves the lever 174 to the right and opens the clutch.

Title: Process for preparing a product having a high hypoglycemisant activity and product thereof
IPC: A61K36/06
Filed: 1957-05-09
Abstract: A hypoglycemisant extract is obtained from edible mushrooms, preferably Psalliota campestris and Cantharellus cibarius, by a plurality of extractions using conventional extraction solvents such as methyl, ethyl or butyl alcohol, acetone, ether, water and chloroform.  An example describes preparing an aqueous pulp of mushrooms which is then extracted with alcohol, the extract admixed with acetone and filtered, the resultant liquid being further extracted with ether and the ether extract removed and a further extraction made on the remaining part.  The combined extracts are then concentrated by heating to 40-50 DEG  C. under vacuum and the resulting residue extracted with alcoholic ether at least twice. These extracts are concentrated as before and their residue extracted with aqueous alcohol to give the final product.  Other examples describe many variations of this process.  The extracts may be mixed with insulin or sulphamides and conventional substances to form compositions for internal and external use.

IPC: B24B3/56
Filed: 1916-10-18
Abstract: 112,639. Wade, H., (Keenc, A.). Oct. 18, 1916. Disk apparatus.-The oppcsite sides of one edge of a metal strip that is drawn continuously through the machine are acted upon alternately by a pair of honing or grinding disks, which may be pressed against the strip by resilient means. The spindles 3 of the disks 4 are mounted in bearings in the brackets 2, which have a swivelling connexion with the stems of the members 9 that are pivoted at 11 on the support 10<a>; this construction allows the faces of the disks to be brought into the desired oblique plane to engage with the strip 5. The pulleys 6 are splined on the spindles, which are moved together, first to the right and then to the left, to bring first one disk and then the other into contact with the strip, by means of a crank on a spindle 20 provided with a driving-pulley 60 which engages a block 31 on a rod 21 mounted to slide in extensions of one of the brackets 2. This rod is coupled to a corresponding rod mounted in the other bracket by an intermediate rod and universal joints. Each rod has secured to it an arm 37, in which is secured a bearing for the outer end of the spindle 3, and between the bearing and a collar 45 secured to the shaft is interposed a spring 44. When the arm moves inwards, it acts upon the spindle and disk through the spring; on its return movement, it encounters a collar on the end of the spindle and carries it back. The strip may be drawn through the machine by a pair of friction rollers; it is supported in a guide formed of two side members held in a support 55 and provided with removable lining-strips. The guide and lining-strips are cut away to allow the disks to approach the strip. A number of machines may be grouped together and driven from a common shaft. The crank on the spindle 20 may be of adjustable throw and consist of a disk with a diametral T-groove, in which is fitted a slide carrying a cranli-pin, which itself carries a slide engaging in a guide-way in the block 31, which is clamped on the rod 21. The slide in the crankdisk is adjusted by a screw in threaded engagement with it, which is prevented from moving endways by a collar on its neck engaging a groove in a seat formed partly in the disk and partly in a cover-plate clamped thereto. The screw is formed with a knob whereby it may be turned. The crankdisk is secured on the spindle by means of a smaller disk, which screws on to a nipple on the end of the spindle and enters a circular recess in the crank-disk, to which it is secured by two screws. The sliding engagement between the pulley 6 and the spindle 3 may be effected by a lug fixed by a screw to a cap screwed on the end of pulley boss and formed with a projection to engage in a groove in the spindle.

Title: Improvements in or relating to a method for periodically removing incrustations on the parts of a crystallizer
IPC: C01D5/00
Filed: 1951-06-25
Abstract: Crystal crusts deposited on the cooling surfaces of crystallizers are removed by blasts of compressed air at room temperature from nozzles which may be permanently fitted in the apparatus or directed as required by hand.  When the blast has blown a small hole in the crust the whole crust on a surface detaches in large lumps.  The operation is preferably performed with liquid removed from the apparatus.  In an example a sodium sulphate solution obtained by evaporating a coagulation liquid for viscose rayon was cooled in a lead lined vessel containing a number of lead covered internally cooled discs rotating on a horizontal axis.  When a thick crust had built up on the discs the salt solution was discharged and the crusts removed by directing a jet of compressed air at 4 atmospheres pressure from a slit 5 mm. wide by 3 cm. long as necessary on to the crusts.  Jets of nitrogen and carbon dioxide are referred to as well as air jets.
