Title: Improvements in primer locks for breech loading guns
IPC: F41A19/57
Filed: 1925-12-29
Abstract: 268,053. Armstrong, Whitworth, & Co., Ltd., Sir W. G., and Forster, G. Dec. 29, 1925. Ordnance breech mechanism. - A self-feeding primer lock of the kind having a removable magazine, comprises a magazine mounted on a slide adapted to move to bring a tube into line with the vent, a lock-slide separate irom the magazine slide, and a detent operated by the lock-slide ior preventing the magazine from moving to the loading position until the spent tube has been extracted. As shown, the drum magazine 1 is rotatably mounted on a sleeve 2 keyed to a spindle 3 projecting from a slide 11. The slide is mounted in a guideway on the box-slide 15 and is pressed towards the vent chamber by a spring 12. A lock-slide 16 carrying the lock mechanism is mounted in the same guideway. The slide 11 is held in its outer position by a lever 20, one end 23 of which engages a projection 22 on the sleeve 2. The other end carries a pin 25 adapted to be engaged by a projection 24 on the lock-slide towards the end of the opening stroke, the magazine slide being thereby released to move to the loading position after the extractor 18 has been operated. The magazine slide is returned to its initial position by the direct action of the lock-slide. During each reciprocation, the magazine is rotated one step by a spring pawl 27 engaging ratchet teeth 26, reverse rotation being prevented by the projecting end 6 of the spring catch 5 which retains the sleeve 2 on the spindle 1. During hand loading, with the magazine removed, a. projection 29 on the slide 11 acts as a tube retainer.

Abstract: 669,026. Luminescent materials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 8, 1946 [Oct. 24, 1945], No. 33190. Class 39 (i). Method of forming a phosphor comprises heating in vacuo a phosphor base material and an activator so as to produce vapours thereof at substantially the same vapour pressure and condensing said vapours on to a common support. The phosphor material can be a fluoride, preferably zinc fluoride, and the activator can be manganese obtained from manganese fluoride, the ratio preferably being ZnF 2  : 0.006 Mn. The heating can be effected in an enclosure evacuated to a pressure of the order of 2 Î 10<SP>-5</SP> mm. of mercury, e.g. in a cathode-ray tube envelope, the phosphor base material and activator being condensed on to the target end of the envelope to form a luminescent screen. The thickness of the deposited material can be from 0.24 to 2.7 microns. The base material and activator are preferably condensed on to a support of " Pyrex " (Registered Trade Mark), although ordinary glass may be used if first coated with a transparent layer not attacked by fluorides, e.g. a layer of nickel or platinium about 0.05 microns thick. Part of the zinc fluoride may be substituted by magnesium or cadmium fluoride, it then being necessary to evaporate more of the base material or activator, whichever has the smaller vapour pressure, than is actually required in the condensate, in order to obtain the desired ratio of base material and activator. Specification 380,256, [Group XX], is referred to.

A semi-crystalline ceramic is made from a composition of which at least 95% consists of 30-48% SiO 2 , 34-54% Ca 2 P 2 O 7  and 15-21% Al 2 O 3 , the weight ratio of Ca 2 P 2 O 7  to Al 2 O 3  being not less than 1À85. This composition is melted to form a homogeneous glass which is shaped to form an article which is then reheated to about 1050‹C., at a rate not exceeding 5‹C. per minute between 850‹C. and 1050‹C., until, as a result of conversion to semi-crystalline form its linear thermal coefficient between 0‹ and 300‹C. exceeds 90 x 10<SP>-7</SP> per ‹C. Preferably the article is held for two hours at 950‹C. and ¢ hour at 1000‹C. the components may be derived from batch materials such as bone ash, feldspar or clay or from purified materials such as sand, lime, phosphoric salts, and alumina. A fining agent is not necessary but 0À1 to 1À0% of ASzOs may be added. Oxidising agents such as AS 2 O 5 , Ca(NO 3 ) 2  or Al 2 (NO 3 ) 3  may be added to neutralise reducing conditions which might reduce the phosphate. Constituents other than those already quoted should not exceed 5%. Thus there may be up to 5% of CaF 2 , MgO, ZnO, PbO, 2% of K 2 O, NazO, or LizO, 3% ZrOz.

Abstract: 986,002. Substation circuits. POSTMASTERGENERAL. Aug. 1, 1962 [Sept. 21, 1961], No. 33865/61. Heading H4K. A subscriber's tone sounder comprises a capacitor C2 arranged to be charged by D.C. over the line and a control device VT arranged on alternate half-cycles of tone current to discharge the condenser through a circuit L2, C3 resonant to current of prescribed frequency; the resonant circuit containing a further coil L3 having a saturable core, and a transducer TD being coupled to said coil. Only when the coil current is sufficient to drive the core from one state of saturation to the other, is the voltage across it adequate to drive the transducer. Thus in a party line system, different tone frequencies can be used, and only in the case where L2, C3 is tuned to the correct frequency will the sounder respond. Moreover, if the line is looped by a talking party the resistance drop over R1, R2 reduces the amount by which C2 is changed to such an extent that response is impossible. In an improvement, Fig. 4, the transistor V1 is provided with negative feed-back over R3 and positive feedback at the response frequency by coil L2W coupled to L2. In addition a circuit L4C4, resonant at the maximum response frequency of TD, is provided together with a threshold device D1, D2 for eliminating weak signals.
