Title: Improvements in and relating to automatic and semi-automatic telephone systems
IPC: H04M7/06
Filed: 1928-05-10
Abstract: 317,120. Standard Telephones & Cables, Ltd., Wright, E. P. G., Baker, J. H. E., and Cameron, A. H. May 10, 1928. Automatic exchange systems.-A single-motion group selector controlled by a common marking switch has access to a number of groups in excess of ten. In the embodiment described, the selector has two sets of wipers and has access to 19 groups, 9 of which are marked by the control switch in response to a first digit other than 2, and the remaining 10 are marked in response to the first digit 2 followed by a second digit, the first digit 2 merely serving to connect up an alternative marking bank of the control switch. The set of wipers of the selector to be used is determined by whether the first digit other than 2 or the second digit if the first digit is 2 is odd or even. Operation when first digit is other than 2. When the selector is taken into use, relay KA energizes in series with relay D in the marking switch, and associates the common marking switch with the selector, extending the loop to the impulse relay A. Relay D removes its lower lowresistance winding from the test circuit to mark busy all the selectors associated with the marking switch. Relay A locks relay D and connects up relay C, and repeats dialled impulses to magnet SCDM, while as soon as the marking switch moves off-normal, a circuit is closed for the selector magnet SDM. Stopping relay H is connected to the control wipers CA, CB so that the selector cannot get ahead of the marking switch. At the end of the impulses, relay C (which was held at back contact 3 of A) relapses and shortcircuits contact 1 of H to allow hunting over the marked group. Relay H energizes when the marked group is reached, and when an idle line is found, test relay HA or HB (according as the dialled digit was odd or even) energizes and switches through. Relay KA falls back and the marking switch is restored to normal. Upon release, relay HA or HB relapses and completes the restoring circuit for magnet SDM. Operation when first digit is 2. In this case, relay F energizes over bank SC2 of the marking switch and locks when relay C falls back, and the selector continues to step until the normal position is reached, when relays H, I energize in series over wipers CA, CB in parallel. A restoring circuit is also closed for magnet SCDM, and in the normal position relay B energizes, locks and releases relays F, H, I. The marking ground is now connected to bank SC5, and in response to a second digit one of the remaining ten groups is marked as described above. Permanent loop. After a certain time, relays E, G become energized over a periodically earthed lead TP, and relay HA operates, releasing the marking switch and lighting an alarm lamp. The selector is released by means of key PGK. All trunks busy. If no idle line is found in the wanted group, the selector continues to step until the normal position is reached, when relays H, I energize in series, and busy tone is connected up.

Filed: 1967-03-23
Abstract: 1,170,547. Reels. SPARTON CORP. 23 March, 1967 [25 April, 1966], No. 13790/67. Heading B8M. [Also in Divisions F2 and G4] A sono buoy has a lower submersible part attached to an upper floating part by a length of nylon cord 12 joined to a lower length of rubber rod 16 which cord and rod are stored on aluminium or nylon spool 35 and in a plastics lined spool 25 respectively. After the sono buoy hits the water a plate (14) (Fig. 13, not shown) held in place by a spring (70a) in a groove (70) becomes detached and allows the submersible part (11) to move away from the upper floating part (10) during which movement nylon cord 12 unwraps itself from reel 35, followed by the extrusion of the rubber rod through the central aperture in the reel 35. Simultaneously signal cable 13 unwraps itself from the outside of reel 28 to form a helix about the extended cord and rod. The nylon cord is retained on spool 35 by a polyurethane foam ring. Polyurethane foam centring strips 26 separate aluminium spacer strips 27 from the signal cable reel 28. The signal cable is retained on spool 28 by a soluble paper strip or by sprayed silastic material. The lower end of the rubber rod is secured by nylon cord 44 to a fixed grommet 42 to which is attached a lower length of rubber rod 16 on the end of which are mounted the hydrophones. Signal cable 13 connects the latter to the submersible part. The hydrophones fall away from the latter after the plate (14) has been detached. Due to the connection of the floating and submersible parts by the rubber rod the hydrophones substantially remain at the same depth as the floating part moves vertically on the waves. In a modification, Fig. 7, wherein nylon cord is deployed after the rubber rod two widths of the rod pass through the central aperture in the plastic insert of spool 35 around which the nylon cord 12 is wrapped. The end of the rod 16 is initially held by a spring 90 which is removed as the two sono buoy parts separate.

Title: Process for the preparation of radioactive iodine-marked compounds
IPC: G21G4/04
Filed: 1965-04-02
Abstract: A radioactive iodine-marked compound is prepared by irradiating in a nuclear reactor a mixture of iodine 131 and an inactive halogen compound having a halogen atom in the position in which it is desired to attach the iodine 131 atom.  For example, a halobenzene is mixed with a solution of carrier-free iodine 131 (as iodide) in aqueous sodium thiosulphate, and the mixture is oxidized with sodium nitrite and sulphuric acid to convert the iodide to iodine. Iodine 131 dissolves in the halobenzene which is frozen in vacuo to remove oxygen before irradiation. Residual iodine 131 is removed by passing a benzene solution of the product through an alumina adsorption column.  If the inactive halogen compound is other than an iodo-compound, the marked compound in a carrier-free state may be separated from the halogen compound by distillation.

In an hydromechanical split-torque transmission an hydraulic coupling 1, 3 is combined with a three-element epicyclic gear comprising an annulus 7, sun 13 and planets 9, and a centrifugal friction clutch 19 so that as the speed increases the coupling slip decreases and a larger proportion of the torque is thereby transmitted directly to the gear output shaft. As shown the outer portion of the coupling runner 3 is connected to the annulus 7 through the clutch 19, and the hub portion is connected directly to the sun-wheel 13. Clutch 19 is actuated by centrifugal masses 39 on spindles 37 passing through the annulus 7, each spindle carrying a sector with teeth 35 meshing with internal teeth 33 on the pressure plate 27, which is moved axially by balls 29 located in conical recesses in the pressure plate 27 and the coupling easing 5, such movement being assisted, if desired, by forming teeth 33, 35 helically. At a predetermined speed clutch 19 is effective to lock the planetary gear for direct drive to output shaft 11. Annulus 7 may have twice the number of teeth of sunwheel 13, so that the hydraulic coupling or the clutch, when engaged, carries about one-third of the total torque transmitted.

Title: Process for the production of sponge rubber from aqueous rubber dispersions
IPC: C08J9/30
Filed: 1935-05-13
Abstract: Sponge rubber is made by adding oxygen-furnishing substances such as hydrogen peroxide, sodium perborate, sodium or potassium peroxide, to aqueous rubber dispersions, with or without the addition of oxygen liberating catalysts such as salts of iron or haemoglobin, causing the liberation of gas, and solidifying the foam thus produced, after moulding if desired.  The dispersion may have additions such as alkali silicofluoride or zinc oxide and ammonium salts, which cause it to gel on standing or heating. Powdered ungelatinized starch also renders the dispersion sensitive to heat.  Formaldehyde, in the presence of the oxygen-liberating substances is converted to formic acid and effects coagulation.  The set foam may be vulcanized in hot air, or in hot water or steam to produce additional micropores. Vulcanized latex may be employed, and the usual additions of fillers, colouring matter &c. may be made.
