Filed: 1939-02-08
Abstract: 524,828. Electric measurement of depth. BRITISH WESTERN UNION, Ltd. Feb. 8, 1939, No. 4152. Convention date, Feb. 19, 1938. [Class 40 (i)] [Also in Group XXXVI] A submarine cable-laying device of the kind described in Specifications 452,141 and 503,326, [both in Group XXXVI], is provided with means for transmitting to the cable laying ship towing the device or some other distant point, indications of the depth of the trench in which the cable is being laid. The transmitting means may comprise a weighted arm 45, Fig. 5, pivoted about a horizontal axis 40 to the framework D of the device, the lower end of the arm dragging over the sea bed adjacent the upper edge of the trench formed by the plough 30 as the device is towed, so that the arm takes up different angular positions in accordance with the depth of the trench framed. The upper end 47 of the arm is connected through a linkwork 50-53 to a spindle 54 attached to the moving arm 77, Fig. 4, of a rheostat 55, Figs. 4, 5 and 6 so that the arm 77 moves over the contacts of the resistance element 76 of the rheostat as the angular position of the weighted arm 45 alters. The contacts are arranged in two semicircular rows disposed side by side with the contacts of one row staggered relatively to those of the other row. The resistance element 76 and its contacts are contained in an oil filled casing 55a, the hydrostatic water pressure being communicated to the oil filling through bellows 80 so that the water is prevented from entering the casing through the gland 60 by which the spindle 54 passes into the casing. The rheostat controls the current flowing in a depth-indicating circuit, Fig. 4, comprising a battery 72, fuse 73, ballast resistance 74 depthindicating milliammeter 75, and rheostat 55, the resistance element of the latter being connected to the milliammeter (which together with the elements 72-74 is carried on the cable laying vessel) by a cable 70. The other side of the circuit from the battery to the rheostat is completed through the water in which the cable is being laid. The ballast resistance 74 permits initial adjustment of the resistance of the indicating circuit, for example to compensate for different lengths of cable 70. Buoys such as described in Specification 524,830, [Group XXXVI], may be attached to the cable 70 to prevent fouling thereof by the cable-laying device.

Title: Improvements in or relating to the repair of ships' hulls
IPC: B63B43/16
Filed: 1944-03-08
Abstract: 597,876. Stopping leakage. CHIPCHASE, R. S. March 8,1944, No. 4325. [Class 113 (i)] For temporarily sealing a hole in a ship's hull, shuttering is applied to the hole by means which do not involve pumping out the water, and concrete or cement is then applied to the shuttering to form a closure for the hole. As applied to a floating vessel holed in the bottom, as shown in Fig. 1, one or more wire nets 1 are secured over the hole by means of external anchorage wires 2 and supported by internal hanging wires 4. Each wire 4 may carry a screw anchorage device comprising a channelled body portion 12, Fig. 8, and a helical rigid rod 14 with a pointed offset end 14a which screws itself into the net 1 when the wire 4 is rotated. One or more tarpaulin collision mats 6 are secured outside the nets 1 by means of anchorage wires 7 and supported by girth wires 8. Bags 9 of cement or dry concrete mixture are dropped on to the nets 1 from inside the vessel and allowed to set under water. Mixed concrete 10 in the liquid state is poured over the bottom of the vessel in layers, each layer being allowed to set before the next is applied, reinforcing bars making this concrete selfsupporting. Distance shores 11 are placed between this concrete surface and the deck beams 5, and the water then pumped out of the vessel, additional shoring being added if necessary. If the vessel is aground and holed at the bottom, the mats 6, and then the nets 1, are placed over the hole from inside the vessel. The Specification also describes and illustrates the application of the invention to vessels, either afloat or aground, which are holed in the side, bilge and bottom, including the use of inside shuttering consisting of horizontal planks of wood slid down guide wires. This form of shuttering may be used on the outside instead of. the mats and nets. Each mat 6 is made of double tarpaulins 6a, Figs. 5 and 6, reinforced by edge wires 6b and cross-wires 6c, all these wires having extensions terminating in bracing eyes 6d. On one side of the mat and at a short distance from its edges there is provided rope thrumming 6e with a canvas backing 6f to form a seal around the hole in the hull. Each net 1 is slightly smaller than the mat 6 and is reinforced by stronger edge wires 1a, Fig. 7, and cross-wires 1c, some or all of which have extensions terminating in eyelets 1b. Two opposite edge wires 6b or 1a may be replaced by rigid stretcher bars. Reference has been directed by the Comptroller to Specification 563,977.

Title: Improvements in the manufacture of synthetic resins
IPC: C08G8/28
Filed: 1928-02-13
Abstract: 315,442. Morgan, G. T., and Drummond, A. A. Feb. 13, 1928. Phenol-formaldehyde condensation products.- Synthetic resins are prepared by heating a mixture comprising a phenol, a solid polymer of formaldehyde, a catalyst, and an organic solvent for the phenol which does not react so as to form part of the resin. A resin solution is so obtained which, after acidification (if the catalyst is one which forms a sparingly soluble salt with the phenol), may be washed with sodium thiosulphate solution and dried, preferably with anhydrous sodium sulphate The dried solution may then be used in known manner or evaporated A purer product may be obtained by mixing the washed and dried solution with benzene or toluene, whereupon the purer product is precipitated. The precipitation may be effected in the presence of an inert pulverulent material such as sodium sulphate, sand, sawdust, powdered glass, or sulphur, from which material, after filtering, the resin may be redissolved either as a whole or in fractions. According to the examples, (1) phenol. paraformaldehyde, and lime are boiled in alcohol and the solution is acidified, suitably by passing sulphur dioxide through it, and then washed and dried; it is then poured into benzene to precipitate a resin which becomes hard and insoluble when heated to 110‹ C., the residual solution containing a less reactive resin; (2) m-cresol, paraformaldehyde, and hydrochloric acid are boiled in alcohol, the bulk of which is finally removed by distillation; the residual solution is washed with hot water and the resin, which does not become insoluble when heated, is dried.

Title: Improvements in or relating to electronic data storage devices
Inventor: BIRD RAYMOND
IPC: G11C11/28
Filed: 1955-02-15
Abstract: 796,334. Electric digital-data-storage apparatus. BRITISH TABULATING MACHINE CO., Ltd. Feb. 15, 1955, No. 4478/55. Class 106(1). A gas-filled diode is connected in a circuit as shown in Fig. 1, lines 4, 11 and 13 being held at 200v, 90v, and 250v respectively, which is such that the voltage across the diode is always less than the striking voltage and greater than the extinguishing voltage except when contact 16 is closed and contact 17 is open when the voltage across the diode rises sufficiently to cause it to strike. Once the diode has struck it can be extinguished by opening the contact 18. The conductive state of the diode can be determined electrically by applying a pulse of very short duration to the cathode via a condenser 25 which will cause a change in potential across the anode load only if the diode is " on ". In a second embodiment, Fig. 2, a 4 Î 2 matrix of gas-filled diodes is used to store, in a binarydecimal code, data read from conventional record cards. The circuitary associated with each individual diode, say diode 21, is substantially the same as in Fig. 1, the contact 17 being replaced by a commutator 29 and brush 26, and being normally closed, and the contact 16 being replaced by a record card-sensing brush 27 and being normally open. Each column of the matrix is controlled by four brushes of the commutator in such a way that as each row of the record card is being sensed only those diodes representative in a " 1, 2, 4, 8 " code of the value of the row being sensed can strike. In this way each decimal digit of the card is transferred to an associated column of the matrix. For read out purposes each diode has associated with it a trigger circuit (only one being shown) which is set to represent the state of the associated diode by the application of a short negative pulse on a lead 25 to the cathode of each diode. In order to prevent these triggers being set during read-in each anode load, which is shown as a choke, but which could be a resistance, is by-passed by a diode 44 under control of a contact 39.

Abstract: 913,775. Copy-milling. ROLLS-ROYCE Ltd. Feb. 10, 1960 [Feb. 10, 1959], No. 4699/59. Class 38 (6). [Also in Group XXII] In a milling-machine for cutting cams (to be used as masters in a copying machine for making turbine blades), an electrically conductive drawing of the cam cross-section is followed by an arcuate spark gap follower which in turn controls an hydraulic ram moving the cutter. The drawing 13a, in metallic ink, and to an enlarged scale, is mounted on a faceplate 13 which rotates with the work-holder which carries the workpiece 12. An arcuate follower 27 having a series of conducting inserts 27a (or a continuous wire), all connected to an E.H.T. supply is mounted on a slide on the machine bed and is movable by an hydraulic ram 28, 29 under the control of an electromagnetic valve 46 so as to keep the spark voltage, and hence the distance between drawing and follower constant. The valve 46 is controlled by a pushpull amplifier, Figs. 5 and 6 (not shown). As the follower 27 moves, so it moves with it a wedge plate 30 and hence the spring-loaded piston of an hydraulic valve 31 which controls an hydraulic ram 21, 22 to adjust the position of the cutting tool 16. There is a mechanical follow-up linkage (Figs. 1 to 3, not shown), between the tool slide and the body of valve 31 to provide proportional control. The tool 16 is rotated by an hydraulic motor 17. The slope of the plate 30 corresponds to the scale ratio of the workpiece to the drawing. The tool 16 is the same radius as the cam-follower which will be used with the finished cam. The radius of the arcuate follower 27 is equal to the scale of the drawing divided by the cam ratio of the cam being produced.
