Title: Self-guiding and target-homing missiles
IPC: F41G7/00
Filed: 1971-05-20
Abstract: 1341745 Acoustic direction-finding THOMSON CSF 20 May 1971 [29 May 1970 10 Oct 1970] 16148/71 Heading H4D [Also in Division F3]  A self-guided, anti-submarine missile having no self-propulsion means, comprises a homing device having two arcuate arrangements of hydrophones 4 and 5, Fig. 4, for detecting the target by means of the sounds emitted thereby, and inclined vanes 2 for rotating the missile as it moves forwardly, the hydrophones generating data which is characteristic of the rate of angular rotation of an imaginary straight line joining the missile and target, in accordance with the techniques of proportional navigation, and employing this data to control the vanes 2 such that the missile homes on to its target. The arcuate arrangements of hydrophones have different radii of curvature and the arrangements are separated by a distance greater than the wavelength of the sound waves picked up. The command signals to the means controlling the vanes 2 are azimuth and elevational correcting signals and are each respectively applied twice per missile revolution, the azimuth correction signal being applied when the plane of symmetry of the vanes coincides with the plane containing the axis of rotation of the missile and the straight line joining the missile and target, and the elevational correcting signals being applied when the plane of symmetry of the vanes is perpendicular to the same plane. The velocity of rotation of the missile is determined by an accelerometer located on the axis of the missile and is introduced into the calculation of elevational transfer. An absolute azimuth reference is furnished by means of a gyrometer associated with an integrator. In another embodiment, the signals from the hydrophones are fed into a gyrometer which is mounted independently of the rotation of the missile and produces a zero detected angular velocity signal, but when the target is found remains aligned in a reference plane containing the target. The electronic circuit for the self-guiding means is as shown in the block diagram of Fig. 5, The separate signals from the hydrophones 4 and 5 are processed in the circuit and are fed into an N.O.P. relay for controlling the vanes 2. The individual circuits for various components of the main circuit are illustrated in the following Figs. (not shown): the acoustic channels 7, 8, 9 and 10 (Fig. 6), the pulse generator 11 (Fig. 9), the azimuthal transfer computer 15 (Fig. 10), the processing circuit 12 (Fig. 11), the elevational transfer computer 18 (Fig. 12), the control generators 19 and 20 (Fig 13). The other embodiment comprising the independently mounted gyrometer is illustrated in Figs. 14 and 15 (not shown). The processing of the acoustic signals includes amplitude and phaseweighting for beam-shaping and is such that ambiguities due to beam side-lobes are avoided.

Title: Improvement in primary cells
IPC: H01M6/10
Filed: 1944-08-30
Abstract: 596,224. Batteries. MALLORY & CO., Inc., P. R. Aug. 30, 1944, No. 16523. Convention date, Dec. 10, 1943. [Class 53] One terminal of a dry cell consists of the metal container 17 with which one electrode is in contact, the other terminal consisting of an insulated metal closing member 18 in direct contact with the other electrode. In the construction shown in Fig. 3, the electrode in contact with the container 17, which is made of iron or steel, consists of a compressed layer 16 of graphite and mercuric oxide or cupric oxide, the bottom and lower parts of the inside wall of the container being painted with a graphite suspension to improve the contact. The electrode 10 in contact with the closing member 18 consists of a strip of corrugated zinc wound into a spiral with a strip of paper and enclosed in a sleeve 12 of polystyrene or other material The zinc strip projects beyond the paper strip at the upper end and the paper extends below the zinc at the lower end 11. The electrolyte is a solution of potassium hydroxide and is absorbed in the paper with which the zinc strip is rolled. Absorption of the electrolyte is carried out before the electrode is placed in the cell by standing it in a bath of electrolyte, the zinc being amalgamated at the same time by placing a quantity of mercury on the top of the roll. The top of the cell consists of an amalgamated zinc disc 18 fitted into a neoprene ring 20 which is held in position by the turned-over edge 21 of the container. A wire 23 is soldered to the disc 18. A porous ceramic disc may be placed between the depolarizer 16 and the lower end 11 of the paper separator. In a modification both electrodes are rolled into a spiral with an intervening insulating sheet. One electrode is of zinc the other consisting of a strip of plain steel or a steel mesh strip pasted with a depolarizing composition of mercuric oxide and graphite mixed with a binder. The pasted strip is baked and pressed between rollers. The rolled electrodes and separator are impregnated with electrolyte and placed in a steel container, the steel electrode extending below the zinc and separating sheet and making contact with the bottom of the container. The zinc projects at the top and makes contact with the closing disc as described in connection with Fig. 3. In another construction the zinc electrode is made by spraying zinc or zinc amalgam on to a strip of paper, cloth or regenerated cellulose. Specifications 579,849 and 596,225 are referred to.

Title: Improvements in and relating to resistance welding apparatus
IPC: B23K11/31
Filed: 1953-06-16
Abstract: 727,862. Welding by pressure. MALLORY METALLURGICAL PRODUCTS, Ltd. June 16, 1963 [June 24, 1952], No. 16577/53. Class 83(4). In a resistance welding electrode holder having a body portion and a sleeve-like member or adaptor nut, said member &c. has a portion engageable with one end of the body and an extension - portion, including an internal flange, for housing the flanged end of an electrode which in one position of the member &c. on the body engages one face of the electrode flange to force the opposite face into contact with the one end of the body and the member &c. being such that in another position thereof on the body the electrode can be bodily removed laterally therefrom. In one embodiment a copper alloy body 10 is threaded at one end to receive a nut 14. A shoulder 15 on the nut engages a shoulder 24 on an electrode 20 and holds an end face 23 of the electrode against an end face 12 of the body. The faces 12, 23 may be silver-plated. The nut 14 is provided with tangential slots spaced 180 degrees apart on the bore of the shoulder 15 and on the bore adjacent to it so that the electrode may be entered laterally into the nut, the shoulder 24 on the electrode passing through the tangential slots in the larger bore. The slots in the smaller bore are extended into the larger bore so that at this point the larger bore extends for more than 180 degrees, thus providing a portion for preventing lateral electrode movement. A nut 26 is secured at the other end of the body and a water connection 28 abuts the nut. An inlet 40 is in communication with a valve 32 secured in the connection and water therefrom flows through tube 32 and a tube 35 therein to a coolant hole 22 in the electrode. The water then flows rearwardly to a space between the tube 32 and a further tube 36, secured in the connection, to an outlet 41. To replace the electrode the nut 14 is slackened so that the shoulder 24 is opposite the 180 degree slot in the larger bore. The connection 28 is then pulled rearwardly, the tube 36 sliding in the nut 26, and the tube 35 is withdrawn from the hole 22 to allow the electrode to be laterally removed. Spring clips 45, 49 on the tube 36 co-operate with grooves in the nut 26 to prevent accidental withdrawal of the connection 28 or the complete assembly passing out through the nut 26. In a modification a spring is arranged in the body 10 so that its force has to be overcome when withdrawing the water connection.
