Abstract: 572,468. Gun carriages. SMITH, W. H. June 24, 1940, Nos. 10828 and 12617. [Class 92 (i)] A field carriage is so constructed that, when the gun is in firing position, one wheel lies flat on the ground, the opposite wheel standing above the gunner and being preferably of disc form to serve as a shield. In the form shown, the carriage with conical wheels is shown turned on its side into the firing position, one wheel A resting flat on the ground to form a training base, the other Q forming a shield above the gun. The axle-tree D, formed of assembled metal plates, supports the elevation trunnions E of the gun F. To lock the gun in training, conical plates G, H are pressed against the wheel A by a screw-device operated by a handle N. The gun is locked in elevation by a clamp V engaging the arcuate portion of a vertical plate extending from the axle-tree D and supporting a front shield Y. Handles a, or an eye d attached to the gun muzzle, form draught means in the travelling position. The plates forming the axle-tree may be connected by tubes forming receptacles for ammunition. Specification 527,342 is referred to.

Title: Improvements in coiling mechanism, for use more particularly with metal rolling mills
IPC: B65H54/40
Filed: 1924-05-03
Abstract: 237,367. Ratcliff, F. G. May 3, 1924. Winding and reeling.-In a coiling mechanism, for use particularly with rolling mills, for reeling strip metal as it leaves the rolls, the reeling drum is driven through a pair of friction members which grip between them a chain wheel &c., one of the members of which is provided with a number of pins &c. projecting through the other member and carrying springs and adjusting nuts &c. for varying the friction in accordance with the size of strip. The shaft 1 of the drum 2 is provided with fixed and loose friction members 3, 6 which are pressed together by springs 8 adjustable by nuts on the connecting-pins 7. A chain wheel is rotatably mounted on a projecting boss on the member 3 and is driven by a chain 6a from a shaft rotated from the rolling mill or other source of power. The shaft 1 is driven unloaded at a peripheral speed greater than that of the rolls, the friction clutch causing the strip to be reeled at a speed corresponding with the delivery of the strip from the roll whilst exerting a pull thereon. In order that the power transmitted to the friction drive shall not exceed a predetermined maximum, the chain wheel 9 is loosely mounted between members 11, 12 on the driving shaft and is connected thereto by grooved pin 10, which will break when a predetermined shearing force is applied, as when delivery of the strip stops during rotation of the reeling shaft. The drive may also be disconnected by removing the pin. A forward and reverse drive for the drum may be used for slacking the reeled metal &c. This may be effected by belts or by bevel wheels and clutch, which may also be moved into a neutral position.

Title: Discriminator circuit for pulse amplitude analysis

Filed: 1963-03-20
Abstract: 1,032,801. Semi-conductor pulse discriminating circuits. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT m.b.H. March 20, 1963 [March 24, 1962], No. 11038/63. Heading H3T. A pulse amplitude discriminator circuit comprises a tunnel diode connected to a bias current source and a signal current source, the signal and bias currents being in opposition, such that when the signal current overcomes the bias current, the diode switches from a low voltage state to a high voltage state. As described, a pair of series-connected tunnel diodes T u1 , T u2  are biased from variable bias circuits T 2 , R 18 , R 16  and T 3 , R 17 , R 15  so that T u1  will switch when an input pulse at E exceeds the lower limit and T u2  will switch when the input at E exceeds the upper limit. If the signal lies between the two limits T u1 switches and the resulting output pulse from it is fed via amplifier T 4 , T 5  to a differentiating circuit R 1 , C 2 . The negativegoing pulse derived from the differentiated trailing edge is then fed to switch tunnel diode T u4  and produce an output signal at OV. If the input signal exceeds the upper limit diode T u2  also switches and the output from T 5  is of sufficient amplitude to switch on a normally non-conducting transistor T 7 , the collector current of which is sufficient to switch tunnel diode T u3  to its high voltage state. This change in voltage renders transistor T 6  also conducting and the collector current of this transistor is sufficient to prevent diode T u4  being switched by the output from R 1 C 2 , so that no output signal is produced. In order to reset diode T u3 , the next output pulse from T 5  is differentiated and the pulse from the leading edge is fed via diode G on to the cathode of T u3 . In a modification, Fig. 2 (not shown), the outputs from T 5 are taken from a delay line instead of from differentiating circuits. Multilevel discrimination may be obtained by using more than the two diodes T u1 , T u2  in the input circuit.

Title: Concentration of plutonium
IPC: C01G56/00
Filed: 1946-04-10
Abstract: 835,212. Concentration of plutonium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 10, 1946 [April 12, 1945], No. 11079/46. Class 39(4). An aqueous solution containing plutonium is concentrated by contacting with columbic oxide which adsorbs plutonium, removing and dissolving the columbic oxide, and contacting the resulting aqueous solution with an insoluble lanthanum compound which removes plutonium from the solution. The cycle of operations may be repeated to effect further purification. In the process described, a solution of plutonium is freed from fission products by a bismuth phosphate precipitation; the precipitate is dissolved in nitric acid and a precipitate of lanthanum fluoride produced by adding lanthanum nitrate and hydrofluoric acid; the precipitate carrying the plutonium is washed with dilute alkali and then reacted with strong alkali to form lanthanum hydroxide, which is washed and dissolved in concentrated nitric acid, zirconium ions being added to assist solution. Columbic oxide is added with agitation to carry down plutonium and is washed and dissolved in hydrofluoric acid, oxalic acid or alkali metal hydroxide. Addition of lanthanum ions produces a precipitate of lanthanum fluoride, oxalate, or hydroxide which carries the plutonium. The precipitate is redissolved and the plutonium further purified by precipitation as peroxide or iodate. Specification 798,685 is referred to.

When the channel is free, the location is used to monitor the channel for signalling characters and to return exchange generated signalling characters to subscribers or trunk path served which situation is shown in Fig. 2. The individual word locations in the time switching cord CQ are read cyclically and synchronously with the appearance on t.d.m. 64 Kb/s highways and cord control logic CCL carries out various functions dependent upon the information held in location read. Each cord location e.g. CLX, includes four fields A-D of information storage; the station status field A stores information byte indicating the state of the channel in the last frame. Each time location CLX is read field A information is compared by COM with any incoming signalling character and any change of state is signalled over lead SCL to control (SPCC), Fig. 1 (not shown). COM is also used to update station status code, field A. The channel served by a cord location within a 64-bit multi-plex may be varied in accordance with information programmed in the field B, the highway cross-point address - as shown H02/H12, consequently each time CLX is read, cross-points X21, X20 will be activated. By this arrangement the incoming character on H12 is fed to comparator COM while information in field D is fed to outgoing H02. To indicate when local subscribers are free, field D is programmed with a clear signal together with an indication in field A that B should be retained. Each input channel therefore will be routed to a time switching cord each time it makes its appearance on an incoming highway, but the cord which serves its particular channel may be changed by a cross-point address reprogramming under the control of (SPCC). The switching function is simplified if the two cord locations for connection of a call are located within the same cord which necessitates the inclusion in the network control algorithm of a facility for dynamic relocation of channels between cords of the same data rate. Figs. 3 and 4 (not shown) illustrate diagrammatically the operations performed in exchange highway time slots X, Y, respectively, in interconnecting subscriber's stations XX and NY.
