Title: Disabling means for reaction motor propelled missiles
IPC: F42B15/36
Filed: 1972-06-22
Abstract: 1440753 Self-propelled missiles DEFENCE SECRETARY OF STATE FOR 1 Aug 1973 [22 June 1972] 29318/72 Heading F3E A reaction-motor propelled missile has a motor with a fuel-containing portion 12 and a venturi portion 14, the missile having disabling means which includes an energy storage means, whereby separation of the portions 12, 14 is effected so that substantially no thrust is generated by the motor, the energy in said energy storage means being sufficient for disabling of the missile and the disabling means also being able to render inoperative starting means for the motor. In an embodiment the portions 12, 14 are located within a casing 10 and an explosive charge 16 is fixed circumferntially around the junction between said portions and can be fired from a control device 18, through electrical conductors 20. When the missile is in flight and under power from the missile motor, the device 18 is continuously in receipt of a radio signal, for example, from the launching site, which inhibits firing of the charge 16. If control of the missile is lost, the signal to the device can be interrupted, this causing the charge 16 to fire and the separation of the portions 12, 14 to be effected. The force of the charge 16 is sufficient to rupture a casing 13 and thus allow the separation of the portions 12, 14 but does not rupture the casing 10. The firing of the charge 16 breaks the starting means circuitry. This is a safety precaution to prevent the charge 16 being accidentally fired prior to the launching of the missile. In a modification the portions 12, 14 are joined by flanges 22, 24, Fig. 2, and a sealing ring 26 which are held together by latches 28, 30, hinged at 32, 34 respectively. The latches 28, 30 are actuated by piston and cylinder devices 36, 38 respectively which are connected to a cylinder 44 containing compressed gas, via a pipe 40 and a valve 42. Starting means contacts (not shown) are opened by the operation of the piston and cylinder. In another modification the cylinder 44 is replaced by a cylinder 46, Fig. 3, having a piston 48 with a piston-rod 40, the latter having a latch 52 formed at one end thereof and having a spring 56 thereon. The latch 52 engages a detent 54 carried by the armature of a solenoid 58, connected to a battery 60 through the control device 18 which, when actuated, causes the detent 54 to release the piston-rod 50 and allow the piston 48 to be driven by the spring 56 so as to compress gas in the cylinder 46, the compressed gas being passed through the pipe 40 to the devices 36, 38, Fig. 2. The latch 52, Fig. 3, also engages an electrical switch 64 which, when the latch is moved by the spring 56, is opened, thus making starting means 62 inoperative.

Abstract: 1,079,558. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 12, 1965 [July 25, 1964], No. 29384/65. Heading B6F. Hammer mechanism.-In a printer having a hammer in each character position along a printing line, the hammers 11 are each resiliently mounted upon a pair of leaf-springs 12, 13 and cocked by an electromagnet coil 21 common to magnets in all character positions, actuation of selected hammers 11 being effected by energization of individual opposing electromagnet windings 24, 25 which thus allows these hammers to operate by spring tension. The cocking by the electromagnets is effected in conjunction with a cam which cyclicly moves all the magnets away from the platen and the magnets flexing all the hammers. The magnets are H-shape, the base of the H being directed to the platen while the top is adjustably secured on to mounting block 37. Pairs of clamps 39, Fig. 7 (not shown) secure the magnets in pairs on to the block and by means of an elliptical key 43 the jaws of the lamps may be opened for adjustment of the position of the electromagnets. Anti-rebound device.-A resilient stop member 66, Fig. 9, is attached to a momentum absorbing mass 63 of the same weight as the hammer 11. The mass 63 is attached by a rubber layer 64 to a bar 65. When the hammers are to be operated the stop members are raised from behind 4 shoulders 67 on the hammers 11 by a pivoting action of the bar 65 mounted on the top of a pivoted lever 71, Fig. 2 rocked by a follower and cam early in a print cycle. After the hammers are cocked the stops rest under the influence of weights 77 on the tops 76 of projections 67 on the hammers. Rebound is prevented by the stops falling behind the shoulders 67 after impression.

Title: Improvements relating to the manufacture of condensation products from aliphatic organic compounds
IPC: C07C29/00
Filed: 1931-10-26
Abstract: Higher alcohols, esters, and other condensation products are produced from oxygen derivatives of paraffin hydrocarbons (other than ethyl alcohol and mixtures of ethyl and methyl alcohols) and hydrogen (but without carbon monoxide) by the action of a mixed catalyst consisting of one or more of the following feebly basic oxides, viz., alumina, uranium oxide and thoria, in admixture with copper, silver, nickel or chromium or a mixture thereof, preferably in quantity not exceeding 10 per cent, and if desired with the addition of a basic oxide such as calcium, barium, strontium, magnesium or lithium oxides.  The quantity of the basic oxide is preferably less than half the catalyst except when the initial oxygen materials contain a substantial proportion of a higher alcohol such as butyl alcohol, when it is preferable to employ a larger proportion.  The temperature may be 150-400 DEG  C. and the pressure from atmospheric to but not exceeding 50 atmospheres.  For the production of high yields of higher alcohols the proportion of the hydrogenating metal should be reduced, but for high yields of higher esters the proportion of hydrogenating metal is increased.  In examples (1) to (3) butaldehyde and hydrogen are passed through an electrically heated aluminium tube containing a catalyst containing 100 parts alumina, 6 parts lime, baryta or magnesia, and 1.5 parts copper, the products being butyl acetate and butyrate, butyl alcohol and higher alcohols; (4) a mixture of methyl and butyl alcohols and hydrogen is passed over a catalyst consisting of 89 parts of magnesia, 8 parts of alumina and 3 parts of copper at 350 DEG  C. and 30 atmospheres pressure, the products being methyl ethyl carbin-carbinol, hexyl, heptyl and higher alcohols; (5) as in (4) but replacing methyl by ethyl alcohol, the products being hexyl, octyl and higher alcohols, including decyl alcohol, and higher ethers.  Specifications 254,819, 337,014, [both in Class 2 (iii), Dyes &c.], and 364,134 are referred to.

Four-stroke-cycle engines.-In Diesel engines which draw air into the cylinder during the first part of the suction stroke, pre-compressed air being admitted towards the end of this stroke, a single slide valve J is used to control the connection of the cylinder to the atmosphere and to the pressure supply The valve moves in the suction conduit 11 and is worked through the lever K from the cam L. The lower part of the conduit 11 is surrounded by a box divided by a partition n<1> into two chambers n<2>, n<3>. The upper position of the corresponds to the first part of the suction stroke and air enters the cylinder through the lower chamber n<3>; towards the end of the stroke the valve moves down and air under pressure enters the conduit II from the chamber n<2> through ports h<1>. The amount of supercharge is determined by the time the valve is in its lower position. At the end of the exhaust stroke the air trapped in the conduit H between the valve J and the cylinder admission valve F is used to scavenge the last part of the exhaust gases; if desired the valve J may be held open slightly at this period to permit air from the pressure chamber n<2> to effect this scavenging. The Specification as open to public inspection also states that in a multi-cylinder engine a single valve such as J may be used for the control of air to two adjacent cylinders.
