Abstract: 548,531. Compound sheet materials. BRITISH CELLOPHANE, Ltd., HEAVEN, G. S., HEAVEN, Z., [Representative of HEAVEN, H. S.] and OSWIN, C. R. March 12, 1941, No. 3391. [Class 140] Water-sensitive non-fibrous sheets or films are laminated by coating one sheet with a cold aqueous adhesive and laminating it to the second sheet within the period of imbibition of the first sheet, the quantity of adhesive used being insufficient to raise the moisture content of the laminated product to the critical value, so that no permanent shrinkage, i.e. less than 0.3 per cent., of the sheet occurs, and then drying the product. The sheet may be of regenerated cellulose, methyl, ethyl or glycol cellulose, partlyacetylated cellulose, cellulose ether-esters, gelatine and organic materials. Suitable adhesives are gelatine-calcium chloride, gelatineacetic acid, gelatine-zinc chloride, " Cellofas " (R.T.M.) with or without glycerine, starch, dextrine, and gum arabic. The time of imbibition may be increased by using sized sheets, e.g. those described in Specification 386,775, [Group IV]. Sheets coated on one side with paint, oil or moisture-proofing compositions such as those described 'in Specification 283,109, [Class 140], may be used. The process may be carried out by coating a web by a rotating roller dipping in a bath of adhesive and removing excess by a doctor knife or by a transfer roller, and effecting lamination by passing the two webs together between nip rollers. The product may be formed into bags, envelopes, seamed sheaths or tubes. Methods of measuring the permanent shrinkage and the time of imbibition are described.

Title: Improvements in or relating to control systems for vapour generating installations

IPC: F01K13/02
Filed: 1964-01-27
Abstract: 1,072,051. Steam turbine plant. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 26, 1965 [Jan. 27, 1964], No. 3411/64. Heading F1T. In a method of controlling the starting up of a vapour generating and superheating unit arranged to supply vapour to a turbine, the temperature of superheated vapour flowing to the turbine is regulated in such a manner that the difference in temperature between the vapour and the turbine casing is maintained at a predetermined value. In the embodiment shown the steam generator comprises steam generating tubes disposed around the furnace 3, a primary superheater 11 and a secondary superheater 13, also a first and secondary steam reheater 15 and a primary steam reheater 17. A steam attemperator 35 is disposed between the primary superheater 11 and the secondary superheater 13. The steam discharging from the secondary reheater 15 passes through an attemperator 41, the attemperator 41, also attemperator 35 being in the form of water spray devices. Superheated steam from the superheater 13 passes through line 37 to the inlet 23 of the high pressure steam turbine 21, the steam from which passes through line 39 to the reheaters 17, 15 then through line 43 to the inlet 27 of the low pressure turbine 31, the steam discharging from the turbine through outlet 29. The temperature of the superheated steam in line 37 is measured at 45 and a signal indicative of this temperature is transmitted to the comparator 53. The temperature of the high pressure turbine casing 21 is measured at 49 and this temperature is also transmitted to the comparator. In the event of these temperatures differing by more than a predetermined amount a signal is transmitted to the valve 63 which controls the rate of flow of water to the attemperator 35 whereby the temperature of the steam passing to the line 37 is reduced. Similarly the temperature of the steam in the reheat steam line 43 is measured at 47 and the temperature of the low pressure turbine casing 31 is measured at 51 and signals indicative of these temperatures are transmitted to the comparator 55. Should the temperatures differ by more than a predetermined value the regulating valve 65 is actuated so as to increase the flow of water to the attemperator 41 so reducing the temperature of the steam passing through reheat line 43. The values of the predetermined temperature differences are controlled by a digital computer 57 and the values may vary during the start-up operation.

An abrasive cutting tool comprises a body 11 of flexible sheet material having a circular peripheral edge, an abrasive coating 15 bonded to the edge, flanges 17 of the coating extending radially along the sides of the body, and peripherally-separated segments 18 of abrasive coating spread around the rim at preselected intervals and extending radially from the flanges, the segments forming a discontinuous radial extension of the flanges and having portions 19 of the body mounted to the flanges for entry of coolant and escape of chips during an abrasive cutting operation. As described, the abrasive coating is provided on the inner rim of the body which may be of stainless steel or phosphor bronze and have a thickness between 0À002 and 0À008 inch, the body being gripped at its outer periphery during use so as to be tensioned. The abrasive which may be diamond dust, overlaps the rim of the body for a distance of 0À003 to 0À002 inch to form the flanges and the segments extend from the flanges several times the width of the flanges, the flanges and segments being 0À002 to 0À004 inch thick. The notches 19 between the segments have less width than the segments. The tool may be used for cutting off thin slices of semi-conductor material.

The fixed core is made concave at its lower end, the movable core being correspondingly convex; projections v of non-magnetic material are carried by the movable core. Sparking contacts 2, z are provided for the main switch. The movable main switch contacts are connected by a flexible lead 4 to a post 5, a latch 8 connecting this post to a terminal 6. The switch has the usual shunt and series coils and may have a further coil in series with the lamp load. A coil 15 placed on the outside of the case b is used as a shunt to the series coil, so that heavy lighting current may be supplied without using thick wire in the coil. A leaking resistance 17 is connected from the main terminal 6 to the fixed switch contacts, to ensure excitation of the generator field at all times. By opening the latch 8, the movable core may be worked by hand to test its condition. The switch is mounted in a box having a lid 19, Fig. 5, held on to a base 18 by wing nuts on the end of 'a rod 25, which passes along the back of the base and has projecting screwed parts 26.

[Also in Divisions B8, E2, F2 and G3] A timing device comprises a bellows which receives atmospheric air at a rate determined by a porous plug and when expanded to a particular extent operates a trigger mechanism. The porous plug may comprise a silicate compound or a natural or synthetic fibrous material. In one example, Figs. 8 and 9, the timing device controls the actuating hammer 91 of an electric switch. The hammer 91 which controls the contact strip 106 engages a helical cam groove in an actuating plunger which is rotatable to vary the interval between depression of the bellows 82 and tripping of the hammer 91. If the plunger 89 is rotated until a pin 99 which extends therefrom engages a pin 102 the hammer 91 is retained out of engagement with the contact strip 106. Several electric timer switches each controlling the succeeding one may be used to control an electric oven.
