Abstract: 793,836. Indicating direction of revolution. ATELIERS DES CHARMILLES SOC. ANON. March 12, 1956 [March 12, 1955], No. 7727/56. Class 106 (3). [Also in Group XXXV] Means for indicating the direction of rotation of an electric pump, Fig. 1, having its rotor 1 immersed in a liquid to be pumped and its stator 6 protected by a water-tight casing 2, comprises one or more permanent magnets 7 on the rotor 1 and means 9, 10, Fig. 2, outside the casing 2, responsive to movement by the magnets 7. As shown, 9 is a disc of conductive metal such as aluminium and 10 is a disc of magnetic metal, said discs being mounted on a shaft 11 carrying a pointer 12 and biased to a central position by a spring 13. The pointer 12 is viewed through an opening 20 against a scale 21 and the whole is enclosed in a casing 8. The disc 10 of magnetic material prevents too great a dispersion of the magnetic field and also sets up a torque, due to hysteresis, enabling very slow rotations to be checked. To increase the torque set up, the disc 9 is preferably formed with radial slots, bars of magnetic material filling these slots being either part of the disc 10 or separate members extending into corresponding slots through both the discs 9 and 10. Releasable means may engage the slots to hold the discs stationary when readings are not required. The distance between the discs 9 and 10 may be adjustable to vary the sensitivity of the device. In a modified form the magnetic disc 10 is not present, the remaining disc being permitted to turn continuously, or stopped by a lever or spring.

Abstract: 1,138,286. Automatic gun feeding mechanism. BOFORS A.B. 22 Feb., 1966 [10 March, 1965]. No. 7779/66. Heading F3C. A feeding mechanism is provided for a gun having at least one magazine mounted to one side of the barrel and comprising a plurality of vertical round compartments arranged sideby-side and each holding a stack of rounds (Figs. 1, 2, not shown). The feeding mechanism includes a stationary baseplate 4 on which is reciprocatably mounted a round feeder carrier 5. The carrier 5 is provided adjacent its longitudinal sides with two sets of feeder pawls 9 spring loaded by springs 11 to their raised position and connected together by shafts 10 and an axially displaceable rod 13. The carrier 5 is urged towards its discharging position, i.e. to the right in Fig. 3, by a feeder spring unit 15, the carrier being driven against this spring unit towards its rest position by an assembly consisting of a reciprocating cam slot bar 20 coupled to the recoiling mass of the gun and a link 21 pivoted at one end to the base-plate and carrying rollers 23, 25 co-operating with the carrier 5 and the cam bar respectively. The feeding mechanism is also provided with two rows 40, 40<SP>1</SP> of check pawls. Each row consists of a set of rearwardly facing check pawls 42 and forwardly facing check pawls 41 pivoted in the base-plate 4 and projecting downwardly from their pivots to co-operate with actuating bars 45, 44 respectively. The bar 44 is spring- loaded such that in the feeding of the rounds, the check pawls 41 are depressed against the spring loading. The rounds may thus be fed along the carrier 5, the pawls 41 reverting to their raised positions after the passage of a round such that a fed round cannot travel back with the carrier 5. The other check pawls 42 prevent the feeding of rounds until they are depressed and this is effected by a spring and lever assembly, the lever co-operating with part of the feeder spring unit 15 (Fig. 4, not shown). The feeder spring unit 15 may be actuated manually (Fig. 6, not shown). Further the feeder pawls 9 may be de-activated by a cam surface 67. The feeder mechanism is further provided with a plurality of guide levers 64 which co-operate with the rounds in the feeding operation. Each round compartment has a locking flap adjacent its lower end such that a round cannot leave a compartment until a space occurs between the open end of the compartment and the carrier 5 (Figs. 1, 2, not shown). The rounds are fed to a waiting position on a pair of flaps 6 and then fed downwardly on to a loading tray by means of a downfeeding mechanism such as that disclosed in Specification 1,073,613.

Title: Material applicator for planographic printing machines
IPC: B41F31/14
Filed: 1939-03-13
Abstract: 526,324. Printing-machines. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. March 13, 1939, No. 8051. Convention date, Sept. 10, 1938. Addition to 506,692. [Class 100 (ii)] In a printing-machine as described in the parent Specification the mechanism for oscillating the rollers 35, 55 for supplying an ink repellent and ink to the forme rollers 34, 62 respectively is modified by employing cams having concentric portions which permit a dwell to be given to these rollers when in contact with a fountain roller 32 and an ink-transfer roller 54, while the operating mechanism continues to move in order to actuate the means for rotating the fountain rollers 32, 51. As in the parent Specification a lever 106, Fig. 2, effects the oscillation of the yokes 38, 59, in which the rollers 35, 55 are mounted, and the lever 106 is fitted with a cam 107 having a concentric surface 112 and a depressed nose portion which engages an adjustably mounted roller 108 carried by the yoke 38. At the commencement of the movement of the lever 106 in a counter clockwise direction the cam 107 moves the roller 35 into contact with the roller 32. The roller 108 then rides on the concentric surface 112 while the arm 106 moves further to operate the ratchet mechanism for rotating the roller 32. The lever 106 simultaneously operates via a link 130 a lever 131 pivoted to the shaft of the ink fountain roller. The lever 131 is fitted with a pawl 137 for operating the fountain roller, and the pawl 137 clicks idly over the ratchet teeth while the cam 132 first moves the roller 55 into engagement with the roller 54, and then the concentric part of it moves past the roller 135 without causing further movement of the roller 55. The pawl continues to move after the roller 55 engages roller 54. When the movement of link 130 is reversed the pawl rotates the duct roller 51, and the roller 55 returns under spring action into contact with the duct. The roller 35 is mounted in a centrally pivoted yoke 37 with capacity of easy detachment. One end of the roller is received in an aperture in the yoke, and the other end in a slot in which it is held by a pivoted clip 140. Fig. 5, normally held in position by a spring 142.

Title: Manufacture of lactones of the cyclopentanopoly-hydrophenanthrene series
IPC: C07J75/00
Filed: 1942-06-15
Abstract: Lactones of the cyclopentanopolyhydrophenanthrene series are prepared by condensing in the manner of the Claisen reaction an ester amide or nitrile of an a  : b -unsaturated acid of this series which contains the side chain in the 17-position and at least one methyl or methylene group in g -position to the substituted carboxyl group with an ester, nitrile or amide of formic or oxalic acid, and subjecting the reaction product to the action of a hydrolysing, lactonising or re-esterifying agent. The condensation is carried out in the presence of alkali metals, their alcoholates or amides as condensing agents. After the condensation, the products are in the form of enol salts which must be lactonised.  The product may, if desired, be decarboxylated and/or reduced.  In examples: (1) An ether solution of D 5 : 6, 20 : 22-3-acetoxynorcholadienic acid methyl ester and oxalic ester is mixed with fresh potassium methylate. The product, treated with glacial acetic acid and extracted with ether gives after chromatographic purification D 5 : 6, 20 : 22-3-acetoxy-21-oxymethylene - norcholadienic acid lactone. Alternative starting materials mentioned are an ester of D 20 : 22 - 3 : 7 : 12 - triacetoxy - nor - chloric acid, of D 5 : 6, 20 : 22-3-acetoxy-21 : 22-dimethyl - norcholadienic acid, of D 20 : 21-3-acetoxy-21-methyl bisnorallocholenic acid.  (2) An ether solution of D 5 : 6, 25 : 26-3-acetoxy-26-methyl-cholestadiene-26-carboxylic acid ester is added to an ether solution of potassium ethylate and the whole mixed with amyl formate.  There is thus obtained a 1-methyl-b 1-[D 5 : 6-3-acetoxy-cholenyl-(24)]-pentadienolid together with a 1 : b 1-dimethyl - g  - [D 5 : 6 - 3-acetoxy - norcholenyl - (23)] - pentadienolid.  If an ester of D 5 : 6, 21 : 22-3-acetoxy-21-methyl bisnorcholadienic acid is used as parent material there is obtained in corresponding manner a 1-[D 5-3-acetoxy-etiocholenyl-(17)] pentadienolid.  D 20 : 22-3 : 7 : 12-triacetoxy norcholenic acid ethyl ester is prepared by treating 3 : 7 : 12-triacetoxy-pregnanone-(2) with bromacetic acid ester.  D 5 : 6, 20 : 22 - 3 - acetoxy - norcholadienic acid ethyl ester is prepared by treating D 5 : 6-pregnenolone acetate with bromacetic acid ester.  D 5, 6, 20 : 22 - 3 - acetoxy - 21 : 22 - dimethyl - norcholadienic acid nitrile is obtained by reacting 21-methyl pregnenolone acetate with the nitrile of a -bromo-propionic acid.  D 20 : 21 - 3 - acetoxy - 21 - methyl - bisnorallocholenic acid is prepared by reacting 3-acetoxy-21-methyl-allopregnone-20-one with hydrogen cyanide, splitting off water, and hydrolysing to form the acid.
