Title: Improvements in synchronised asynchronous machines
IPC: H02K17/26
Filed: 1925-10-26
Abstract: 251,587. Eclancher, J. V. May 1, 1925, [Convention date]. Drawings to Specification. Alternating-current induction machines; exciting.-For obtaining a distribution of magnetomotive force as nearly sinusoidal as possible in a self-excited or separately-excited synchronous machine started asynchronously, the secondary winding acts as field winding and is connected in delta for three-phase, but for two-phase, the phases are unequal and the larger alone is supplied with continuous current. In the case of a separately-excited machine, the starting rheostat is arranged to cut out all resistance before the field circuit of the exciter is closed. In the case of other polyphase secondary windings, the phases must be arranged in three or two groups. Secondary windings of the type employed in the known " G÷rges " motor may be employed in order to introduce the continuous-current, excitation only at the end of the starting-up operation and in this case a smaller starter or a shortcircuiting switch may replace the usual starter.

Title: Improvements in or relating to a blower valve arrangement for a rock drill
IPC: B25D9/14
Filed: 1950-11-06
Abstract: 683,043. Percussive drills. CHICAGO PNEUMATIC TOOL CO. Nov. 6, 1950 [Jan. 28, 1950], No. 27050/50. Class 124. A blowing valve arrangement for a pneumatically operated percussive drill having a distributing valve admitting live air to a reciprocating piston and a blowing arrangement for removing detritus from the drill hole comprises a blower valve adapted to be locked in a position in which the drill is inoperative but allows live air to be directed into the hole being drilled, and, on being unlocked to return automatically to the drilling position, and means to provide remote control of the blowing valve. As shown, with the blowing valve 45 in the blowing position, the live air enters through a stop valve 33 into a chamber 31, through bores 29 in a ratchet mechanism 18, through ports 40 into the distributing valve and through ports 23 in the front of the valve to the upper part of the cylinder, forcing the piston into the forward position. Part of the air passes through an exhaust port 47 to a slot 59 in the blowing valve 45, through a passage 44 and by pressing on the front face of a flange 37 of the distributing valve maintains the latter in the rearward position; the remainder of the air passes through a rifle nut 14 and a bore in the piston to the tool 72. On altering the valve 45 to the drilling position, Fig. 2 (not shown), the pressure on the front face of the flange 37 is momentarily cut off and pressure on the rear face is continued causing the sleeve 36 to move forward and start normal drilling. The valve 45, Fig. 5, comprises a barrel 50, having two slots 59 and 60, rotatable in a sleeve 49 having a slot 55. A handle 51, pivoted in a slot in the valve barrel, slides in a groove 56 and is urged into a slot by a torsion spring. Movement of the handle in a direction away from a washer 52 moves it out of the slot and the torsion spring 53 urges it along the groove 56 into the drilling position. A cord 68 attached to the handle provides remote control of the blowing valve. During drilling water or air may pass through a tube 48 to the drill bit. Specification 597,920, [Group XXVI], is referred to.

Abstract: 1,183,414. Process for peptides. E. R. SQUIBB & SONS Inc. 13 June, 1967 [22 June, 1966], No. 27176/67. Heading C2C. [Also in Division C3] In a process for preparing polypeptides by the '' solid phase " synthesis an insoluble bydroxymethyl substituted polymer is used to form the covalent ester bond between the polymer and the C-terminal amino acid of the projected peptide. The peptide is split off by hydrolysis with acid, NH 3  or N 2 H 4  according to whether a free acid or amide is desired. Esterification of the polymer is effected with the acid halide or the acid and a condensing agent, e.g. dicyclohexylcarbodiimide or carbonyl diimidazole. Suitable polymers are derived from styrene and divinylbenzene, cellulose, polyvinylalcohol and sulphonated polystyrene. An example describes the preparation of Z-Val-NH 2  and BOC-Val-OMe from a Z-Val-CO-polymer by reaction with methanolic-NH 3  (where Z is carbo-benzoxy).
