Abstract: 1368716 α-Sulphoacylamino-cephalosporins TAKEDA YAKUHIN KOGYO KK 28 July 1972 [29 July 1971] 35475/72 Addition to 1300692 Heading C2A Novel α-sulphoacylamino-cephalosporins having the Formula (I) and salts thereof, wherein R<SP>1</SP> is hydrogen or an aliphatic, aromatic or heterocyclic group and R<SP>2</SP> is a heterocyclic group are prepared by either (a) reacting a corresponding α-sulphoacylaminocephalosporanic acid (or a derivative thereof wherein the acetoxy group in the 3-acetoxymethyl group is replaced by a group which is similarly capable of nucleophilic replacement by a heterocyclic thiol group) with a heterocyclic thiol of formula R<SP>2</SP>SH; or (b) acylating a corresponding 3 - heterocyclic - thiomethyl - 7- aminocephalosporanic acid with the appropriate α-sulphocarboxylic acid or an N-acylating derivative thereof. The group R<SP>2</SP> may be a 5- or 6- membered monocyclic or fused heterocycle containing one to three hetero atoms selected from N, S and O, e.g. a pyrimidine, pyridine, tetrazole, thiazole or thiadiazole ring, optionally substituted, e.g. by NO 2 , NH 2 , SH, Cl, Br, CH 3  or C 2 H 5 , and/or partly saturated. The nitrogen atom may be quaternary. The group R<SP>1</SP> may be C 1 -C 10  alkyl, phenyl or substituted (e.g. halo) phenyl, tolyl, naphthyl or thienyl. Groups capable of nucleophilic displacement at the 3- position include halogen, thiol, hydroxy, acyloxy and substituted acyloxy groups. The N- acylating derivatives of the acid are typically the halides, acid anhydrides, active esters and azides. Reaction (a) is preferably carried out in a polar solvent at alkaline pH in the presence of potassium thiocyanate. Acid reactants may be used in the form of their salts or easily decomposable esters.  Pharmaceutical compositions having antibiotic activity against Gram-positive and Gramnegative bacteria comprise a cephalosporin of Formula (I) or a non-toxic salt thereof and a pharmaceutically acceptable carrier or diluent.

Title: Improvements in and relating to brush shifting mechanism for dynamo electric machines
IPC: B65D41/04
Filed: 1930-11-25
Abstract: 368,320. Controlling alternating current commutator machines. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hull, J. I. ; 1338, Dean Street, Schenectady, New York, U.S.A.) Nov. 25, 1930, No. 35480. Convention date, Nov. 27, 1929. [Class 35.] Relates to shifting the brushes of a motor of the Schrage type, such as that described in Specification 25358/11, [Class 35, Dynamoelectric generators &c.], to regulate the speed and consists in keeping one brush stationary while the other is moved to a certain distance from it and then moving them in opposite directions with the same angular velocity ; it is stated that the power factor is thereby maintained at a value approaching its maximum over a considerable portion of the speed range. For this purpose the brushes 14, 15 are mounted on a rotating yoke 18 and the brushes 16, 17 on a yoke 19. The yokes 18, 19 are connected by links 22, 23 to a bolt 26 sliding in a slot C, D, E in a fixed plate 31. The portions C, E of the slot are radial and the portion D is approximately the arc of a circle. When the bolt 26 is in the middle of the portion D of the slot the pivot 24 of the link 22 is at the centre of this portion and the brushes are in position for synchronous running. As the bolt 27 moves through the portion D the brushes 14, 15 remain stationary and the brushes 16, 17 move ; as the bolt moves through the portions C and E of the slot the brushes move in opposite directions with the same angular velocity. To give an exceptionally high or low torque at starting the slot C, D, E is formed with an extension F, Fig. 8, at one end formed as the arc of a circle the centre of which is at one of the pivots 24 when the brushes are in the corresponding position, whereby one of the brushes is given a movement apart from the other. The handle 35 which operates the bolt 26 and links 22, 23 may also operate the starting switch 41 as shown. To the handle 35 may be pivoted a handle 34 arranged to engage with a rack 39 and connected to the handle 35 by a spring 37, so that when the handle 35 is released after the proper manipulation for starting it is automatically brought into the position appropriate to any desired speed.

Title: Improvements in or relating to automatic direction finders
IPC: G01S3/42
Filed: 1938-12-06
Abstract: 522,129. Automatic control systems. STANDARD TELEPHONES & CABLES, Ltd., and BRAENOLE, E. W. Dec. 6, 1938, No. 35527. [Class 38 (iv)] [Also in Group XL] Alignment.-A directional aerial is combined with a non-directionial aerial to produce a cardioid response, from which two vectors of opposite phase are utilized to rotate the directional aerial, or the search-coil of an associated radiogoniometer, into a position of equilibrium which varies with the direction of a distant transmitter. The voltages across the search-coil C of the radiogoniometer G of the. directive aerial system (not shown) is fed to two amplifiers V3, V4 in parallel. The voltage from the non- directional aerial AE is similarly fed to amplifiers V1, V2. The output from both sets of amplifiers is combined in the transformers T1, T2 (of which the primary winding Sl from amplifier V1 is reversely wound to the winding S2 from amplifier V2) and the resultant is applied in push-pull to amplifiers V5, V6. The output from the latter is applied to the windings A, B of an asynchronous disc-motor M of the kind described in Specification 522,130. The motor M is geared to the search-coil C and under the control of the coils A, B tends to rotate it into the position of maximum pick-up. This gives the bearing line, as indicated by a pointer on the shaft of the coil. " Sense" is determined by opening the switch SW, whereupon the pointer moves to a position corresponding to the " minimum" point of the cardioid curve. The motor M may be replaced by a differential relay for driving the coil C, and the aerial system or field-coils may be rotated instead of the searchcoil.

In one form, two self - heating electrodes 1, 2 are arranged close together in a pear-shaped envelope 6 which is enclosed in an evacuated or oxygen-filled container 9 carrying a cap 10 in which an inductance 7, serving to lengthen the arc 8, is mounted. The envelope 6 is mounted on a frame 11 supported by a band 12 on the pinch 13. The inductance may be arranged below the arc.

Either the chuck inner surface or the bit surface may be coated with material to increase friction. The means 57 may be a multi-strand spring, Fig. 4. When the handle is pushed down, a cam surface 36 opens a valve 32 admitting pressure to passages 27, 28 leading to beneath the piston 4. The piston rises, exhausting air above it through ports 38, jacket 40 and holes 41 when it passes the ports 38, pressure beneath the piston is released. Pressure builds up above the piston causing a valve ring 25 to rise and cut off communication between passages 27, 28, thus admitting pressure to the upper cylinder end via ports 26 to return the piston and deliver a blow to the bit. As the descending piston passes the ports 38, pressure builds up beneath it for cushioning and loss of pressure behind it enables to ring 25 to again close the ports 26.
