Abstract: 1,180,113. Rolling. MORGARDSHAMMER A.B. 16 Feb., 1967 [16 Feb., 1966], No. 7545/67. Heading B3M. [Also in Division F2] In a rolling mill coupling wherein a spindle 1 is universally connected to an externally splined block 3 and an internally splined sleeve 5 connects the block 3 to an externally splined hub 7 on a roll journal 9, a pneumatic or hydraulic servo (24), Fig. 4 (not shown), moves the sleeve 5 axially to disengage the coupling. A tongue 10 on the end of the spindle 1 lies between slippers 2 journalled within a cylindrical bore in the block 3. Springs 16 press a lubricant retaining sealing ring 12 into engagement with a flange 11 on the spindle 1 and urge the spindle into engagement with a thrust pad 17 on the block. The ends of the bore in the block 3 are sealed by caps (13) Figs. 1 and 3 (not shown). The sleeve 5 is connected by a bearing 19 and ring 18 to an arm (20) vertically movable in a frame (21) which is moved axially by the servo (24). When the coupling is disengaged spring, pneumatic or hydraulic means supports the coupling and a projection (27) on the arm (20) engages a corresponding projection (28) on the roll chock to align the block 3 and hub 7 prior to engagement of the coupling.

Title: Improvements in or relating to magazines for rounds of ammunition
IPC: F41A9/64
Filed: 1945-04-03
Abstract: 592,714. Magazines for ammunition. HYDRAN PRODUCTS, Ltd., and MOTLEY, L. April 3, 1945, No. 8188. [Class 92 (ii)] A magazine for rounds of ammunition comprises a shoot in which the rounds are stacked and along which they are biassed towards the gun by a presser device, the latter being provided with wheels or rollers which run on trackways longitudinally of the shoot and beingurged along the shoot in the rear of the stack by a rotary prime mover. In one construction, Figs. 2 and 3, the magazine is applied to rocket-launching mechanism as in Specification 588,920, and comprises a shoot 4 mounted on a breech chamber 2 and containing rounds of ammunition 3. A carriage 5 formed of bent sheet metal is placed on the uppermost round, and on this carriage is mounted an electric motor 8 which through gearing as shown in Fig. 3 is adapted to drive a gear-wheel 24 loosely mounted on a shaft 25. A coiled spring 26 surrounds the shaft 25 and is connected at one end to the wheel 24 and at the other end to a collar 27 fast on the shaft. Both ends of the shaft have gears 28 meshing with gears 29, the latter being mounted on shafts carrying sprockets 6. These sprockets and also guiding blocks 14 and rollers 15, 18 of the carriage travel in channel pieces 16 and within these channels are fitted fixed chains 7 with which the sprockets engage. In operation, the motor 8 keeps the spring 26 continuously tightened and each time a round is fired the spring will rapidly relax to move the carriage down one step. A pawl and ratchet wheel are provided to prevent the motor moving in the reverse direction, and in use the motor is energized before firing to stress the spring 26. In a modification, Fig. 6, the rounds are moved downwards by pressers 32 connected to the adjacent runs of endless chains which pass around upper and lower sprockets in channel guides 45. A shaft 36 passes through these guides and carries the upper sprockets '34 and a collar 40, the latter having secured to it one end of a coiled spring 37 whose other end is fixed to a rotatably adjustable collar 51 also on the shaft. In use, when it is desired to load the shoot, a handle 41 is fixed to the shaft and rotated to raise the pressers above the normal position of the uppermost round, the spring being tensioned at the same time. A ratchet-wheel 42 and a co-operating pawl to prevent unwanted movement of shaft whilst loading, these being disengaged and the handle removed when the shoot is filled. In a further modification, Figs. 7 and 8 (not shown), mechanism substantially similar to that shown in Fig. 6 is employed, but incorporates an electric motor for stressing the spring. Specification 584,743 also is referred to.

Abstract: 492,757. Fluid-pressure servomotorcontrol systems. AKT.-GES. KUHNLE, KOPP, & KAUSCH. March 20, 1937, No. 8265. Convention date, April 7, 1936. [Class 135] A governing arrangement for power engines comprises a linkless flat spring governor 1 which actuates by means of a stirrup-shaped member 11 connected to the governor sleeve 2, a pilot valve 3 controlling a supply of pressure fluid to a piston 4 for actuating, a valve 5 controlling the supply of driving medium to the engine. A follow-up device between the power piston 4 and the pilot valve comprises an auxiliary piston 6 which on movement of the power piston 4 applies fluid-pressure to a piston 9 to adjust the spring loading 10 acting on the governor sleeve to return the pilot valve 3 to its neutral position. A leakage port 14 is provided in the piston 9 so that the pressure built up by movement of the power piston 4 falls away as the engine speed returns to normal. A further loading spring 15 is adjustable to control the governed speed of the engine. Reference has been directed by the Comptroller to Specifications 178,330, [Class 57], and 405,981.

Title: Improvements in or relating to the polymerization of hydro-carbons
Inventor: SHAPIRO ISADORE
IPC: B01J21/00
Filed: 1957-03-13
Abstract: Mono-olefins or acetylenes of two to four carbon atoms are polymerised at 10 DEG  C.-150 DEG  C. in the presence of an oxide of the gel type in which hydrogen atoms of the chemically bound hydroxyl groups of the gel structure have been replaced by -BH2 or -B(OH)2 groups to give a surface modified gel.  Suitable starting hydrocarbons are ethylene, propylene, isobutylene, acetylene and methyl acetylene.  Specified gels are alumina, silica, magnesia and mixtures thereof and they are modified after drying to remove all adsorbed water by reaction with diborane which reacts with -OH groups to give -OBH2 groups which may be reacted with water vapour to convert them to -OB(OH)2.  In examples a silica-alumina catalyst is reacted with diborane and used to polymerise acetylene to benzene, methyl acetylene to trimethyl benzene and ethylene to hexane and cyclohexane; alumina after reaction with diborane is used to polymerise acetylene to benzene.ALSO:Silica, alumina and magnesia gels or their mixtures are surface modified by replacing the hydrogen atoms of the chemically bound hydroxyl groups by -BH2 or -B(OH)2 groups.  After drying to remove adsorbed water the gel is reacted with diborane which converts -OH groups to -OBH2 groups which can then be reacted with water vapour to form -OB(OH)2 groups.  If desired the number of hydroxyl groups in the gel may first be reduced by heating at above 150 DEG C. thereby reducing the amount of bound boron in the product.  The modified gels are useful as catalysts in polymerizing olefins or acetylenes.

Title: A process for the production of aminoguanidine bicarbonate

Abstract: 1,218,209. Aminoguanidine bicarbonate. FARBENFABRIKEN BAYER A.G. 21 Feb., 1968 [24 Feb., 1967], No. 8385/68. Heading C2C. Aminoguanidine bicarbonate is prepared by a process which comprises reacting calcium cyanamide with monohydrazine sulphate or dihydrazine sulphate or hydrazine hydrate and sulphuric acid in an aqueous medium thereby obtaining aminoguanidine in dissolved form and precipitated calcium sulphate, removing the calcium sulphate sludge followed by precipitating and removing the aminoguanidine in the form of the substantially pure bicarbonate salt, the reaction between the finely divided calcium cyanamide and the hydrazine being carried out at a pH value of 7 to 9À5 and at a temperature in the range of 15 to 90 C. The pH value is preferably regulated by the addition of sulphuric acid. These may be precipitated by the addition of alkali metal bicarbonate, ammonium bicarbonate, carbon dioxide together with an alkali metal hydroxide or carbon dioxide together with ammonium hydroxide. Low cyanamide concentrations are preferably maintained for at least as long, as hydrazine amounts of more than 10 to 30% of the initial cencentration are present in the reaction mixture to avoid the formation of dicyandiamide which would otherwise occur in an alkaline medium. Iron impurities present in crude calcium cyanamide are not present in the product since they may be removed before the precipitation of aminoquanidine bicarbonate in the form of precipirated ferric hydroxide by the introduction of air at pH 7À5 to 8À5, or alternatively the precipitation may be prevented by adjusting the pH of the solution separated from the calcium sulphate sludge to 3 to 4.
