Title: Apparatus for cleaning sheet material
IPC: B08B3/12
Filed: 1957-04-29
Abstract: 826,702. Cleaning transparent sheets. LIBBEY-OWENS-FORD GLASS CO. April 29, 1957 [May 15, 1956No. 13504/57. Class 138(1). An apparatus for cleaning sheet material, in particular glass, by passing it through a tank of liquid in which its top surface is subjected to vibration from transducers and its bottom surface is vibrated by reflection from reflector plates below the sheet. A glass plate 20 passes through the washer 23 which consists of three successive sections :- a thickness gauge section 24, a transducer section 25 and a rinse section 26. A roller conveyer 27 comprising rolls 34 rests on piers 28 and is powered by motor 29 through chains 32. Squeegee rolls 41 and 42 advance the sheet 20 into the gauging section where a pivoted roll 57 moves levers 51 about bearings 52 and controls the swtiches 50 which are capable of stopping the motors if a thick or buckled sheet should reach this point. The transducer section, Fig. 6, has vibrating surfaces 66 opposed by reflecting surface 67 placed between rolls 34. The transducers are cooled by coolant flowing from pipes 69 and out of spouts 68. Any liquid, including such solvents as detergents, acids, or kerosene may be used in the tank. Brushes 73, in the rinsing section are kept in contact with the glass sheet by rolls 74. To reduce wear the transducers are rendered inoperative when there is no sheet between them by switches positioned at the entrance and exit of the transducer section. The presence of a sheet closes one or both of these switches, energises a relay and sets the transducers into operation.

Title: Process and apparatus for lining the inside of a tube
IPC: F16L55/165
Filed: 1965-03-30
Abstract: 1,044,645. Lining pipes. E. J. L. NELVA. March 30, 1965, No. 13516/65. Heading F2P. A process for lining a metal pipe (Fig. 1, not shown), disposed in the ground consists in passing under pressure from the inlet of the said pipe to its outlet a sheath of which the leading open end is turned back and secured at the inlet end of the pipe, the pressure in the sheath being such as to apply it to the internal surface of the pipe and to ensure its adherence there by adhesive. The interior of the pipe is first derusted, and washed in known manner and may be coated with an adhesive. The sheath is a plastic tube which is reeled flat off a drum (Fig. 1, not shown), over rollers 22 and between an adjustable roller nip 18-18 into a sealed pressure chamber 8. The front end of the chamber 8 is sealingly connected to the end of a flexible tubular junction member 6 by a collar 9. The end of the sheath is turned inside out at C 2  and its open end clamped around the end of the member 6 by the collar 9. The member 6 is relatively short and its other end is connected to the pipe to be lined by another collar similar to that at 9. A pocket of adhesive may be formed inside the sheath at 21 which serves to introduce more adhesive on to the outer surface of the sheath at C 2 . The chamber 8 has an inlet (not shown) for air-pressure which produces forces F on the sheath, causing it to be drawn, first through the member 6 and then through the pipe and adhered to their inner walls. When half the sheath has been drawn into the pipe so that it is all wound off the reel, a cable is attached to its rear end to control the speed at which its front end moves forward and turns inside out.

IPC: B23H7/22
Filed: 1968-03-20
Abstract: 1,223,302. Making electrodes and aerofoil section blades; spark erosion. ROLLS-ROYCE Ltd. 20 March, 1968, No. 13580/68. Headings B3A and B3V. [Also in Division C7] A passage 15, 16, 17 is provided in a blank formed by two mating parts 11, 12 from which an aerofoil section blade is subsequently produced by making a former having a surface with at least one raised portion, electrodepositing a metal layer on to said surface of the former, separating the metal deposit from the former, and using the raised surface of the deposit as a spark erosion or electrochemical machining electrode to form a groove or grooves in each part of the blank so as to provide the passage in the blank when the two mating parts are assembled. As described, a former 20, Fig. 1, is produced by casting a wax or a low-melting point alloy into a steel master electrode similar in form to the working electrode shown from its non-working rear face 23 in Fig. 2. Six of these formers are jigged together and coated with an epoxy resin varnish on the side and rear surfaces on which electroplating is not to occur and are then immersed in a cyanide copper-plating bath at 50‹ C. containing 162 g/l copper cyanide. Periodic reverse plating is commenced at 5 ASF for 30 minutes and when a smooth surface coating is obtained the current density is raised to 20 ASF and plating is continued at a deposition rate of 0À002 inch/hour until a deposit of thickness 0À080 to 0À100 inch is obtained. The assembly is then removed, washed and dried and the electrodeposit freed from the former, this being facilitated if a release coating of colloidal graphite or molybdenum disulphide has been applied to the former before plating. Release of the deposit is effected either by cutting through the epoxy varnish into the former and immersing former and deposit in boiling water or by blasting the former with steam to remove most of it and then freeing the deposit by a short immersion in saturated copper nitrate solution, followed by a quick dip in cold nitric acid. The freed electrodeposit is then washed in water, degreased in acetone and machined to shape. A reinforcing backing of solder, sprayed copper or brazing wire may then be applied. The electroformed electrode is then used to form depressions 15, 16, 17 in the mating non- cylindrical surfaces 13 of the blank parts 11, 12, these parts thereafter being brazed together to form a composite blank from which is machined a gas-turbine engine blade with a passage through it. Instead of a low-melting point former, the former may be injectionmoulded from a plastic and prior to electroforming rendered conductive by silver lacquering, silver-mirroring or by vacuum deposition. Reference is made to producing nickel instead of copper electrodes.

Title: Improvements in telephone systems
IPC: H04Q3/00
Filed: 1926-05-28
Abstract: 276,442. Standard Telephones & Cables, Ltd., (Deakin, G.). May 28, 1926. Automatic and semiautomatic exchange systems.-A group of numerical switches are provided with common controlling relays, a, set uf which are associated with an individual switch over a hunting switch only during the setting of the switch. A system employing group selectors of the trip spindle type is described, with 5 sets of controlling relay for 50 group selectors, each set having a 50- point finder switch for association with the selectors. Upon seizure of the group selector, relay AR energizes, locks, connects up start relay GSR and puts selectable potential on terminal p. Relay GSR connects up the magnets PC of the finders and when one of the finders reaches the seized selector, test relay CTIR operates, energizing relay CT2R, which connects in the low resistance winding of relav CTIR. Relay CT2R also completes the fundamental circuit fiom the register-controller over terminal q to line relay CLR, which pulls up and energizes relay COR. The trip-spindle magnet P2 operates, revertive impluses being sent back until tha fundamental circuit is opened at the registercontroller. Line relay CLR falls back, and cannot re-energize since relay COR remains locked up. The wiper magnet P1 now operates, and when an idle line is found, test relay CT3R energizes over terminal r. and connects up its low resistance winding in series with relay CT4R. The latter energizes switching relay BR, which locks over the test wire and releases relay AR, which frees the common controlling apparatus. Relay BR completes restoring circuits' for theselector upon release.

Title: Apparatus for determining a magnetic field for the magnetic compass adjustment
IPC: G01C17/38
Filed: 1924-06-13
Abstract: 239,914. Shimizu, S. June 13, 1924. Magnetic tests.-The horizontal and vertical components of a magnetic field are determined for compass adjustment by the use of a coil carrying a current. For determining the horizontal component a coil C, Fig. 1, is vertically supported by a gimbal in the binnacle from which the compass bowl is removed, and within the coil is situated a small compass having a counterpoise W to keep it horizontal. The coil C is adjusted vertically by a rack and pinion H and is rotatable about a vertical axis perpendicular to the centre of the compass card, being fixed in any position by a set screw. The coil C is connected in series with a reversing- switch, battery, regulating-resistance and ammeter. A current is passed through the coil C, which is then rotated until its plane is brought into coincidence with the magnetic needle, and the value of the current is read, the angular position of the coil C being read by a pointer F'. The strength of the horizontal component of the field is determined by the principle of the sine galvanometer, the constant of the instrument being determined from a test in a known magnetic field. The ordinary magnetic compass may be employed, the coil C being made of rectangular or other shape corresponding to the compass bowl. For measuring the vertical component a coil C, Fig. 6, is supported horizontally by nuts F and pivots S1, S1<SP>1> on the gimbal, from which the compass bowl is removed, levels L, L<1> being provided. A small cylindrical case B containing a magnetic needle movable in a vertical plane is mounted on a support A so that the plane of rotation of the needle is parallel to the magnetic meridian. A current is passed through the coil C and adjusted until the needle is horizontal. The strength of the vertical component is then determined by equating the magnetic and mechanical moments acting on the needle, the constant being determined by a test in a known field.
