Title: Warhead
IPC: F42B3/00
Filed: 1974-07-19
Abstract: 1469665 Shells; missiles; land mines; sea mines MESSERSCHMITT BOLKOW BLOHM GmbH 19 July 1974 [25 July 1973] 32154/74 Heading F3A A warhead for an anti-aircraft artillery shell, a rocket propelled missile, a land mine or a sea mine comprises an oxygen-carrying substance which by the effect of heat and pressure on the detonation of an explosive gives off free oxygen to facilitate combustion of combustible material carried by the target. The oxygen carrying substance comprises sodium nitrate, potassium nitrate, potassium chlorate, potassium perchlorate and potassium permangate alone or in admixture. In one embodiment, Fig. 4, a shell comprises an explosive K4 which in the proximity of, or on impact with the target, is detonated to scatter pre-shaped splinters SK4 in a hemispherical configuration. After a delay to allow for fuel to escape from ruptured pipes and tanks &c in the target a further explosive RH4 is detonated and this scatters further pre-sized splinters S4 and particles of an oxygen-carrying substance RA4 in the same direction as the splinters SK4. The latter, as a result of the heat occurring and owing to reaction with the released oxygen, become incandescent and ignite the mixture of fuel and oxygen. To ensure ignition of the fuel/oxygen mixture a further explosive charge K4 is detonated after a delay to scatter particles of an oxygen-carrying substance R14 and particles E4 of iron, aluminium, magnesium, zirconium or thermo-aluminic mixture whose surface temperature is such as to ignite the fuel/oxygen mixture if not already burning. The material of the particles E4 can be used to form the casing or parts of the casing of the shell. In another embodiment, Fig. 3, the shell is provided with hollow charges HZ3 and HU3, the explosive RA3 of which is detonated from the rear by a charge ZA3 that communicates with a nose Z3 through a channel ZL3.

IPC: C04B41/45
Filed: 1921-12-01
Abstract: 173,738. Tetlow, T. Jan. 3, 1921, [Convention date]. Composite bricks, blocks, and slabs.-Objects resembling stone are obtained by sprinkling fragments of natural stone upon the surface of a mould of foundry sand by means of sieves, pouring in a backing of cement mortar, and filling up the mould with a coarser mortar or concrete. The larger pieces of stone are first distributed in the mould and are followed by progressively finer grades, concluding with sand either mixed or not with cement. Part of the fragmentary material may be first distributed upon a sheet of paper or like substance coated with adhesive, and transferred from this to the surface of the mould, the facing layer being then completed as before by means of sieves. The fragments may be arranged in the form of a design or inscription upon the paper. The Specification as open to inspection under Sect. 91 (3) (a) describes also the casting of cement compositions in moulds of foundry sand without special preparation, the facing layer, if required, being applied after casting. The use of stencil plates, &c. to protect, during the sprinkling operation, parts of the mould to be afterwards coated with fragments of a different nature is also described. This subject-matter does not appear in the Specification as accepted.

Filed: 1922-11-24
Abstract: 195,574. Garrett & Sons, Ltd., R., and Luiggi, M. L. Nov. 24, 1922. Couplings for tractors, road vehicles, and trains. -In tractor and trailer combinations in which the front wheels of the trailer are deflected from the straight ahead position for steering purposes through a smaller angle than the drawbar, this result is attained by a simple linkage without the use of reduction gearing. In the construction shown in Figs. 1 and 2, the front wheels 4 of the trailer are steered from the draw bar 7 by an intermediate lever 10 pivoted at 11 to the tractor frame and by transverse links 14. The drawbar 7 is pivoted at 8 to the trailer and actuates the intermediate lever 10 through a sliding joint 9. The proportions of the several elements of the linkage are such as to ensure smaller angular movement of the wheels than of the drawbar 7. In a modification, the intermediate lever 10 is dispensed with.

Title: Improvements in weighing apparatus for use with concrete mixing apparatus
IPC: B28C7/04
Filed: 1926-12-20
Abstract: 263,797. Ahlers, J. G. Dec. 26, 1925, [Convention date]. Automatic-feed weighers. - An apparatus for weighing cement and water in the requisite proportions for delivery to a concrete-mixer comprises receptacles respectively for cement and water operatively associated with a balancing mechanism, a valve-controlled conduit for supplying water to the water receptacle, means controlled by the balancing mechanism for closing the valve when the receptacles reach a balanced relationship providing any desired predetermined ratio of water to cement, means for adjusting the balancing mechanism so as to vary the ratio of water to cement, and means for discharging the contents of the receptacles into the concrete mixing apparatus. The cement is placed in a receptacle 19 pivoted upon one arm of a balance beam 14 fulcrumed on a support 13 and carrying on the other arm the liquid receptacle 24. The receptacle 24 may be adjusted along the arm by means of a screw 25 and a hand wheel 26. A lock 47 may be applied to the hand wheel after adjustment. The water is admitted to the receptacle 24 through a pipe 27 valve 29 and spout 30 by turning a weighted arm 32 from the vertical position to the horizontal position shown. A hook 34 attached to the spindle of the arm 32 is, at the same time, brought into engagement with, and retained by, a latch pin 37 carried by a spring- pressed member 36 pivoted upon the balance beam. When the requite quantity of water has entered the receptacle 24 the consequent depression of the balance beam liberates the hook 34 and the weighted arm 32 falls and cuts off the supply. The cement is then tipped into the concrete mixer by means of a handle 23 and the water is allowed to run out of its receptacle and down a conduit 44 by raising a valve 41 by means of a hand lever 42. Instead of providing automatic means for cutting off the supply of water, the apparatus may be arranged to cut off the supply nf dry cement.

Abstract: 428,019. Locks &c. REINER, T., 7, Klenzestrasse, Munich, Germany. Nov. 9, 1934, No. 32249. Addition to 385,902. [Class 44] The fastening described in the parent Specification is modified by providing two sliding bolts 2, 3 instead of one, for co-operation with the fixed and movable keepers 8, 10. Both bolts are retracted from outside by a key which rotates a lug 30 to lift a tumbler 7 pivoted on the bolt 2 and then engage a heel 2b on the bolt. The lifting of the tumbler brings its lower end 33 into line with a lug 34 on the bolt 3, so that movement of the bolt 2 and tumbler retracts the bolt 3. A pawl 15 pivoted in the lock casing at 14 has a lug 16 which engages a pin 17 on the bolt 3 when the latter is retracted. A sliding member 18, urged towards the slot 13 in which the keeper 10 works, is pressed back by the inclined side of the keeper when the door is closed, so that a cam 21 thereon lifts the pawl 15 and releases the bolt 3, which then enters the keeper slot 29. When the door is moved to the ajar position, a lug 22 on the bolt 3 engages a lug 23 on the keeper to prevent retraction. Both bolts may be retracted from the inside by a handle 28 on the bolt 3, a lug 4 on the latter engaging the bolt 2 during retraction. The bolt 2 may be separately retracted by an inside handle carrying a link engaging a pin 27 on the bolt.

Abstract: 924,682. Supply systems for high-pressure gasfilled discharge lamps. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 22, 1959 [Sept. 25, 1958], No. 32251/59. Class 38 (4). [Also in Group XX] A device such as a high-pressure discharge lamp in a motion film projector comprises means whereby the lamp is caused to emit a light flash during each frame of the film whilst during the intervals between the frames the lamp is energized to a degree insufficient to cause it to emit light. Closure of a switch 14 prepares a relay 8 to close contact 13 and a switch linked to the switch 14 switches on the projector motor 15 which drives a pulse generator 17. When the motor 15 is up to speed the output of the generator 17 by way of a rectifier 22 overcomes the bias produced by a winding 21 on a transformer 12 whereupon valves 10, 11 become conductive, relay 8 is energized to close contact 13 and the discharge lamp 1 is then energized from a stand-by source 16 which does not cause the lamp to emit light. The pulses developed by the generator 17 are applied to a gas-filled valve 2 by way of a transformer 18 to cause the valve 2 to become intermittently, conductive during which periods a capacitor 5 charged from a D.C. source 3, discharges through the lamp 1 causing it to emit a light flash having a short duration. Should the valve 2 remain conducting for an abnormal period the potential developed across a resistor 9 causes the valves 10, 11 to cut off, so de-energizing relay 8 and opening switch 13 to isolate the lamp 1.
