Title: Improvements in or relating to fuse mechanism for aeroplane bombs and the like
IPC: F42C1/08
Filed: 1929-02-14
Abstract: 306,486. Wahrdstrom, J. W., (Assignees of Utter, E.). Feb. 21, 1928, [Convention date]. Protectile fuzes.-A fuze mechanism for an aeroplane bomb is provided with a removable nose pin 21, Fig. 2, adapted when in place to make direct contact with the target and thereby to produce insta.neous firing by bearing directly against a hammer 3, Fig. 1, and driving it on to a detonator, whereas when the pin is removed, the hammer moves forward against a spring 6 on impact, and when retardation is over is driven back by the spring thereby firing the detonator after a short delay. As shown, the hammer 3 is normally locked by centrifugal bolts 2 which move outwards when the bomb rotates during its fall and the detonator 9 is held away from the hammer by a spring 19 and by a distance sleeve 8 which is locked in place by the bolts 2. The hammer 3 is itself held in by the spring 6. When the bolts 2 move outwards during the fall of the bomb, they release both the hammer 3 and the sleeve 8, and this sleeve falls down into the space 25 and prevents any return of the bolts 2 to the locking position. On impact, the detonator 9 compresses the spring 19 and the hammer 3 compresses the spring 6, and firing is delayed and occurs when these parts rebound. When instantaneous action is desiredi, a plug 23 is unscrewed from a nose-piece 20, the pin 21 is inserted through this nose-piece, and the plug 23 unscrewed to the outer end of the pin 21. When the bomb fitted with this appendage strikes the ground, a wire 24 is sheared and the pin 21 is driven in and forces the hammer 3 on to the detonator 9 at once, without delay. The detonator 9 contains a charge of tetryl 14, a primary detonator 12 secured to the ferrule 11 by a nut 13, and a percussion cap 10, and is loose in a tube 15 screwed at 16 to the head-piece 1 of the bomb. The recess in the explosive charge of the bomb for the accommodation of the detonator is lined with a sheet metal tube 17 with a flange 17<a>, and this liner is held in place by a screwed disc 18 formed with perforations 18a. For safety during storage and transit, the detonator is withdrawn, the parts 20, 21, 23 are kept in the space thus left vacant, and a set-screw 26, Fig. 3, is screwed into a tapped hole 7 in the hammer 3, which then grips the bolts 2 by friction and thus prevents accidental unlocking.

Title: Hydraulic mechanism
IPC: B60T11/224
Filed: 1930-02-15
Abstract: 348,691. Fluid-pressure brakes. LLOYD, H. J., Thorpe Lodge, Thorpe-le- Soken, Essex, and RICHARDS, S. H., 10, Patten Road, Wandsworth Common, London. Feb. 15, 1930, Nos. 5131 and 7360. [Class 103 (i).] Hydraulic brake mechanism, in which some free movement of the parts takes place before the full power is applied comprises two pumps 7, 3, Fig. 1, of different diameters and operated by the same member, the piston 6 of the larger pump being operated through a spring 8 or the like which is at all times held compressed without the pressure being transmitted to the piston in the off position. During the first part of the movement of the pedal 5, the pressure of the comparatively large quantity of liquid displaced by the piston 6 acts through pipes 18, 19 on the pistons 21 attached to the shoes, and quickly moves them against the brake drum 31. When the liquid pressure rises to a certain point, a differential valve 23, previously held open by a spring 24 is closed, and further movement of the pedal compresses the spring 8, while the piston 2 of the small pump applies further pressure to the shoe pistons 21. In a modification, the piston 6, Fig. 2, of the large pump surrounds the smaller pump, and the differential valve is dispensed with. The lever 5 acts on the piston 6 through the smaller piston 2 and a spring 8, which is compressed when the liquid pressure produced by the larger pump rises above a certain point, and allows the smaller piston to move in its cylinder 3.

Title: Temperature controlling circuit

Filed: 1963-02-08
Abstract: 958,193. Transistor switching circuits. STANDARD TELEPHONES & CABLES Ltd. Feb. 8, 1963 [Feb. 15, 1962], No. 5240/63. Heading H3T. [Also in Division G3] Temperature of an object is stabilized by controlling an electric heater H z  by a transistor circuit which includes a negative temperature coefficient resistor R1 as a temperature detector and a Zener diode Z1 to determine the switching condition of transistors T2 and T3. If temperature falls, the collector current of T1 through R3 falls also until the potential at point 1 is sufficiently negative for Z1 to conduct; this unblocks T2 and T3 causing Hz to restore the temperature, when the reverse action takes place. In a practical arrangement (Fig. 2, not shown) the supply, from a bridge rectifier, is smoothed by a diode and capacitor, and the voltage across R1, R2 stabilized by a second Zener diode. A resistor (R7) is chosen to compensate for voltage variations across T1 and Z1 and a second negative temperature coefficient resistor is connected across R4 to compensate for the effect of ambient temperature on T2 and T3. R2 is subdivided so that a suitable value can be selected.

Title: Improvements in or relating to the preparation of alcohols
Inventor: FIELDING JOHN COLIN
IPC: C07C29/54
Filed: 1964-02-07
Abstract: Alcohols are prepared by hydrolysing in a continuous or batchwise process an alkoxide or an aralkoxide of a Group II or III metal using an aqueous solution of sulphuric acid with a strength not greater than 30% by weight in the presence of a surface-active agent.  If the process is continuous the strength of the acid used may be increased to 35%.  The preferred starting materials are the alkoxides and aralkoxides of aluminium, particularly those alkoxides containing 6-40 carbon atoms.  A particularly suitable alkoxide is one prepared from a metal alkyl derived from an olefin obtained by the thermal or catalytic cracking of hydrocarbon feedstock such as that produced in the refining of crude petroleum oils.  The metal alkoxides and aralkoxides used as starting materials may be obtained by reacting the corresponding metal alkyl or aralkyl with oxygen.  Before hydrolysis the alkoxide or aralkoxide may be dissolved in a solvent, for example an ether or a hydrocarbon.  Suitable surface-active agents may be anionic, cationic or nonionic. Particularly suitable surface active agents are condensation products of an alkylene oxide with a phenol or an alcohol, salts of alkyl aryl sulphonic acid, primary, secondary and tertiary amine salts, quaternary ammonium compounds and other nitrogenous bases such as guanidine and thiuronium salts.  The preferred amount of surface active agent used is from 0.01 to 0.3% by weight based on the total quantity of aqueous acid.  Specifications 763,081, 763,824, 770,707, 794,359 and 804,355 also are referred to.

[Class 100 (iv)] Paper supports.-The tape-roll holder 8 of a teleprinter is mounted at the rear of the machine on a supporting member 9 readily removable from and replaceable in position. As shown applied to a combined keyboard transmitter and teleprinter, an angle member 2 stiffened by a quadrant 4 is fixed to the rear of the machine, the members 2, 4 having inturned edges 3 so forming a groove to receive the edge of a plate 9 carrying the tape holder secured by a clip 10. A vertical strip 6 fixed to the member 2 has a transverse arm 7 which engages a channel member 12 on the plate 9 when the latter is in operative position. In this position the plate is secured by the engagement of a notch 11 thereon with a struck-up tongue 5 in the groove. The inner edge of the plate bears against and is held by a clip 13 on a vertical rail 14 which together with the member 2 and side plates 15 form a receptacle for messages. The tape is guided by rollers 17, a roller mounted in a part 18 of a lever 19, and a roller 22 to paper feeding mechanism described in Specification 582,528. The lever 19 pivots about the axis of the upper roller 17 and carries a block 20 pressed against the rim of the tape-holder 8 by the action of a spring 21 on the lever 19. During its feed, the tape under tension and by its action on the roller at 18, causes the block 20 to be moved away from the holder 8. Plates 25, 26 which are grasped by the operator to remove the plate 9, prevent damage to the tape.
