Title: Improvements in apparatus for separating sheets in sheet metal packs
IPC: B21B39/00
Filed: 1925-10-26
Abstract: 253,407. MeCrery, H. E. Oct. 26, 1925. Separating sheets in pack rolling.-The sheets of a pack are separated by opening one corner of the pack and projecting the individual sheet corners through a series of stationary bars where the corners are gripped by fingers of a moving carriage which drags the sheets through the bars to separate them. A carriage 74 moved by driven endless chains 54, and provided with gripping fingers 100, grips the corners of the sheets and drags them through a curved row of bars 37 provided with loose sleeve collars 45. The bars 37 are spring mounted at their ends to distribute any extra stress. The series of fingers 100 are forced together automatically to grip the sheets, by blocks 93, Fig. 14, on the chain engaging with the cam faces of levers 146, while the whole carriage is momentarily held locked. Further movement of the block 93 releases the locking device so that the carriage proceeds to drag the sheets through the bars 37. When the carriage arrives at the end of its travel with the separated sheets it contacts with a shock absorber while the blocks 93 on the chain pass down round the sprockets and release the grip of the fingers on the sheets, which are then removed by hand. A crank and sliding crosshead permit the carriage to slide up and then back on the rails while the chains travel on their sprockets. A spring link in the gripping device permits more or less spacing between the fingers to grip thicker or thinner sheets.

Filed: 1937-10-05
Abstract: 492,424. Gas-blast switches. MASCHINENFABRIK OERLIKON. Oct. 5. 1937, No. 26981. Convention date, Oct. 8, 1936. [Class 38 (v)] A gas-blast switch in which both contacts are in the form of hollow contacts through which the quenching medium flows in opposite directions, is arranged so that the medium flows through one contact into a space which is in communication with the atmosphere, and through the other contact into a completely closed chamber, wherein a pressure not substantially exceeding atmospheric obtains prior to separation of the contacts. The quenching medium, after cessation of the supply, flows back from this chamber through the hollow contacts and the space communicating with atmospheres, The fixed nozzle-contact has a reservoir 4 communicating with atmosphere over either a small hole, Fig. 1 (not shown), or a filter comprising, for example, pipe sections or metal clips 14 closed by a grid 13. The movable contact 10 leads by way of aperture 11 into a closed reservoir 16, substantially at atmospheric pressure. A sealed-off part 19 of the reservoir 16 accommodates the operating mechanism, and the blast-inlet 1 to the chamber 2 is by way of the supporting insulator 24. When the supply of quenching medium ceases, the reservoir 16 exhausts to atmosphere by way of contacts 10, 3 and reservoir 4.

Title: Improvements in or relating to electric circuit interrupters
IPC: H01H31/28
Filed: 1935-10-02
Abstract: 453,468. High tension switches. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburgh, U.S.A.- (Assignees of Crabbs, H. J. ; 513, Hill Avenue, Wilkinsburgh, Pennsylvania, U.S.A.) Oct. 2, 1935, No. 27190. Convention date, Oct. 11, 1934. [Class 38 (v)] Contacts.-A circuit interrupter comprises movable blade members adapted to bridge contact devices carried by spaced insulators, and actuating means for moving the blade members to open and closed position and adapted to effect a relative longitudinal movement between the blade members after the latter have been moved to closed position. The actuating means include means for positively controlling the movements of the blade members at all times during the opening and closing operations. An insulator 7 rotatable in a bearing 9 carries a crank member 15 having sets of lugs 57, 59 in which are pins 65, 67 by which the member 15 is coupled through universal joints 69 and links 61, 63, with the movable contact structure 17. The latter comprises a pair of tubular members 33, 35, of which 33 is pivoted by means of a pin 49 and Y-shaped member 47 to a bracket 19 on a fixed insulator 5, whereas 35 is pivoted by means of a Y-shaped member 51 and a pin 53, to a pair of levers 39 also pivoted at 49. Member 47 is formed with a pair of lugs 55 for connection to the link 63. The members 33, 35 are pivotally interconnected by links 37 in the vicinity of the fixed jaw contact 13. The latter comprises a jaw 23 having an arcuate surface 27 for making line contact with a flat surface 45 on member 35, and a jaw 23 having a toothed surface 25 for engaging a similar surface 43 on member 33. The insulator 5 carries a plate 71 which is apertured to receive and provide a bearing surface for the base 73 of crank 15. In the closed position, Fig. 2, the link 61 and crank 57 are at the dead-centre position, whereas link 63 and crank 59 are over-centre. Thus when rotating 7 anticlockwise to open the switch, no movement of 33 occurs as the parts 63, 59 move to the dead-centre position, but the parts 61, 57 at once exert a pull on member 35, causing the surface 45 to disengage surface 27 with a wiping action, and at the same time releasing the pressure between 43, 25. On continued movement of 7, the structure 17 moves outwards from the Fig. 1 position. The reverse process takes place in closing the switch. A pair of lugs similar to 59 are provided at 79, so that by connecting 63 to 79 opening of the switch may be effected by clockwise rotation of 7.
Patent GB-814276-A (GB)
Title: 3-sulphanilamido-5-methylisoxazole and a process for its preparation
Filed: 1957-08-29
Abstract: The invention comprises 3-sulphanilamido-5-methyl-isoxazole and its preparation by condensing 3-amino-5-methylisoxazole with a p-aminobenzenesulphonyl halide or ester, or with a benzenesulphonyl halide or ester p-substituted by a group convertible to an amino group by reduction or hydrolysis and subsequently so converting the p-substituent.  Suitably the p-substituent may be an acylamino or carbalkoxyamino group which is converted by hydrolysis, or a nitro group which is converted by reduction.  The condensation is preferably carried out in an inert solvent or in a basic or basified solvent such as pyridine, picoline or acetone-sodium bicarbonate.  In an example acetyl-sulphanilyl chloride is condensed with 3-amino-5-methylisoxazole and the resulting 3 - acetylsulphanilamido - 5 - methylisoxazole is saponified with aqueous sodium hydroxide to 3-sulphanilamido-5-methylisoxazole.  3-Amino-5-methylisoxazole is made by hydrolysing ethyl (or benzyl) 5-methylisoxazole-3-carbamate. Specification 595,775, [Group IV], is referred to.
