Title: Improvements in or relating to clockwork-operated fuses for projectiles
IPC: F42C9/04
Filed: 1926-03-23
Abstract: 251,223. Schwob FrÞres et Cie, Soc. Anon., and Varaud, A., (Assignees of Tavannes Watch Co., Soc. Anon.). April 30, 1925, [Convention date]. Projectile fuzes. - Relates to clockwork fuzes of the kind in which a spring striker 10 is held by a detent 11 adapted under the combined action of centrifugal force and a spring to swing out and release the striker when a notch 16 in a crown wheel 15 of the clockwork mechanism comes opposite a toe 17 on the detent. The detent is unlocked by an inertia device on discharge and bears against the crown wheel during flight. According to the invention, friction on the clockwork is reduced by preventing the detent from bearing on the crown wheel until just before the appointed time. In Fig. 1, the detent 11, which is pivoted at 12, has a pin 13 which is held by a hook 19 pivoted on the striker 10 until the hook is deflected by a finger 21 on the crown wheel just before the notch 16 reaches the toe 17. In Figs. 3 and 6, the detent 11 is held by a spring bolt 23 until this is lifted out of the way by the finger 21 acting on an inclined face 23<11> on the bolt. Friction is further reduced by tapering the approach 15<1> of the notch 16.

Title: Wet vacuum pumping apparatus
IPC: F04D13/16
Filed: 1927-03-23
Abstract: 280,779. Marks, E. C. R., (Jennings, I. C.). March 23, 1927. Pumping-machines and apparatus. - In a wet vacuum pumping apparatus the liquid and gas pump D, C are secured to the side of the tank B and the driving motor M is also supported by the tank. The pumps are mounted on a common shaft E and are arranged in housings with passages communicating with the tank. A circular shoulder on the tank wall receives the flange 12 on the bracket 11 which carries a circular flange 14 supporting the motor. The pumps and the motor can thus be secured as a unit to the tank. The base A which supports the tank is formed as a drip pan 15 whith au outlet 16. A shaft 18 passes through a stuffing box 19 in the tank and through a lug 17 on the inside. It carries a yoke 20 to which is attached an arm 22 and float 23 operated by the water of condensation. The outer end of the shaft is provided with an arm carrying a yoke 25 sliding between nuts on a shaft 26 which controls the motor switch. Specification 192,365 is referred to.

Title: Improvements in collection of pyrogenic titanium dioxide pigments
IPC: B01D46/02
Filed: 1969-02-17
Abstract: 1,212,471. Ti02 pigments. CABOT CORP. .17 Feb., 1969 [16 Feb., 1968], No. 8512/69. Heading C1N. In a process for making TiO 2  by gas-phase oxidation of titanium tetrahalide, TiO 2  is separated from its resulting suspension in reaction by-product gases by cooling the suspension from above 1450 F. to below 600 F. introducing water into it while its temperature is below 600 F., but above 200 F.. and then passing the cooled suspension through a porous filter material. The amount of added water, liquid or steam, is at least 0.1% by wt. of TiO 2  in the suspension and is sufficient to hydrolyse all unreacted titanium'and other metal halides which may be present in the suspension. The dislodgment, mechanically or by reversed gas flow, of TiO 2  particles from the filter is facilitated and " blinding " of the filter, with consequent increase in pressure drop across it, is reduced. In an example, steam is injected into a TiO 2 - laden gas stream containing aluminium chlorides and cooled by recycling effluent gases and by heat-exchangers. The stream is then passed through bag filters constructed of felted polytetrafluorethylene fibres.

The oxygenation may be effected directly with a submerged culture of the specified fungi grown under aerobic conditions or alternatively by first separating the active enzymes from the corresponding aerobic cultures of the fungi and using them with the exclusion of the growing cultures. Specified starting compounds are cortexone, 9,11- or 11,12-dehydro-cortexone, 16a -hydroxy-cortexone, 18-oxo- and 18-hydroxy-cortexone, corticosterone, 11-epi-corticosterone, 11-dehydrocorticosterone, 18 - hydroxy - corticosterone, progesterone, 17a  - progesterone, 11 - ketoprogesterone, 11a  - or 11b  - hydroxy - progesterone, 9,11- or 11,12-dehydro-progesterone, 19 - oxo - progesterone, 19 - nor - progesterone, pregnenolone, 21 - hydroxypregnenolone and aldosterone.

D 1,4 - 3,11,20 - Triketo - 21 - hydroxypregnadiene is obtained by subjecting 11-dehydrocorticosterone to the action of Calonectria decora.  D 1,4 - 3,20 - Diketo - 11b ,21 - dihydroxypregnadiene is obtained in a similar manner from corticosterone.

Title: Power steering gear
IPC: B62D3/04
Filed: 1951-04-16
Abstract: 679,346. Fluid-pressure servomotor-control systems. ROSS GEAR & TOOL CO. April 16, 1951 [July 15, 1950], No. 8832/51. Class 135. A power-assisted steering gear comprises a manually-operable rotatable and axially movable cam acting on a lever connected to the steerable member, yielding means to centralise the cam in the axial direction, a control device consisting of two relativelv movable members of which the first moves in response to axial movements of the cam, means independent of the cam for adjusting the relative position of the two members of the control device, and a power motor responsive to the control device and connected to the lever. In an embodiment, rotation of the steering wheel rotates a shaft 45, Fig. 1, on which a helical cam 17 is slidably keyed. The cam is centred by helical springs or by spring washers 33, and it engages one end of a lever 18 carried by a rock shaft 12 connected to the dirigible wheels of the vehicle. Provided that the resistance to movement offered by the lever 18 is not greater than the resistance of springs 33, the rotation of the steering wheel will be communicated directly to the dirigible wheels. If, however, the lever 18 is relatively immovable, rotation of shaft 45 will cause axial movement of cam 17 and this movement will be communicated through a lever 68 to a piston valve 67 to connect the two ends of a piston and cylinder power device 53 to a hydraulic pressure supply and to exhaust respectively. The stem of piston 53 engages the upper end of lever 18 so that the movement of the piston consequent on the movement of valve 67 will rotate the rock shaft 12 and, at the same time, will slide cam 17 axially to re-centre the valve. The lands of the latter are narrower than the ports in the valve liner and this negative lap interconnects the two ends of the cylinder and allows a continual flow of fluid from supply to exhaust when the valve is in the neutral position. The housing for the device has aligned openings 49 and 39 at opposite sides thereof so that the power device and the shaft 45, respectively, can enter the housing on either side thereof. To alter the relative position of the valve piston and liner, an end cap 95, Fig. 3, is removed and the valve piston 67 is rotated by means of a slot 94 in the end thereof. The valve piston is thus advanced axially on a screwed shaft 70 at the opposite end thereof until it occupies the desired position in relation to the liner.
