Title: Improvements in or relating to merocyanine dyestuffs
Inventor: KENDALL JOHN DAVID
IPC: C09B23/10
Filed: 1947-06-04

Title: Improvements in automatic feed water regulators
IPC: F22D5/14
Filed: 1921-05-28
Abstract: .180,211. Dubois, M. May 28, 1921. Feed-water, supplying and controlling. - In automatic feedwater-regulators of the type in which the expansion and contraction of an horizontally-disposed thermostatic tube in communication at one end only with the interior of the steam-generator at the normal water-level is used to actuate the feed-valve, the thermostatic tube is provided with ribs or fins of a material different from that of the tube, to facilitate radiation and to accentuate the variation in temperature by rapid cooling when the tube becomes filled with water. The effects of variation in steam pressure (and temperature) on the valveactuating mechanism are neutralized by one or more tubes to which one end of the thermostatic tube is attached. Assuming the valves 5 and 9 to be closed and the water-level to fall below normal, the brass thermostatic tube 23 becomes filled with steam by the communicating pipe 24, which dips into the generator at the normal level, and expands. One end of the tube 23 is attached by a cross-piece 28 to compensating tubes 26 in communication at one end with the steam space of the boiler and attached at the other end to a wall 11 of a box 12 containing the valve-actuating mechanism. The resultant push on the lever 17, which is thus unaffected by variations in steam pressure in the generator, is then utilized to open the spring-controlled auxiliary valve 9 and admit feed-water by a pipe 8 from the feed supply side of the fed-valve E to the right of a piston valve-member 3 sliding loosely in a sleeve 4 in the casing and always under generator pressure, and so open the spring- controlled valve 5 and admit feed-water to the generator. When the level of the water in the generator rises above the mouth of the tube 24, the steam in the thermostatic tube 23, and tube 24 will condense and the tubes will become filled with water. The temperature of this water will rapidly fall owing to the large amount of radiating surface on the thermostatic tube 23 provided by the shrunk-on steel fins 23<a>. As the tube 23 contracts, the valve 9 closes and the equilibrium of pressure resulting, as the water to the right of piston valve-member 3 flows to the opposite side through the loose fitting sleeve 4, allows the valve 5 to close, cutting off the feed supply, whereupon the cycle may be repeated. This apparatus is suitable for pumps of the ordinary plunger, duplex, geared, and direct-acting types feeding one or several boilers. When a pump of the duplex type is used to supply but a single boiler, or when the feed-water is supplied by means of an automatic injector or a turbine, a modified form of regulator in which the expansion of the thermostatic tube is made to open a balanced double-beat valve, is employed.

IPC: G11B3/20
Filed: 1928-05-24
Abstract: 315,951. Electramonic Co., Ltd., Tyrrell, S. J., Sayers, D. W., and Tyrrell, L. N. May 24, 1928. Electric pick-ups and the like, supporting.-An electric gramophone pick-up or like reproducer or recorder is connected to a supporting arm by means of a plug and socket having interfitting electrical contacts. The socket may be provided on the end of the arm, and the plug on the pickup, or vice versa. In each of the various constructions shown, the pick-up 8 is provided with a plug 11 which projects from the casing of the pick-up and engages in a socket member secured in the end of the supporting arm 1. Contacts of various form may be provided in the socket, the number, form, and arrangement of the contacts being suited to the particular construction of plug employed on the pick-up. For example, in the socket shown in Fig. 1, a metal sleeve 19 and a spring-pressed plunger 20 are provided in an insulating block 18. The sleeve 19 is connected to a lead 23 running through the supporting-arm 1, and when the plug is inserted therein it makes direct contact with the plug, to which one end of the winding of the pick-up is connected. The other end of the winding is connected to the casing of the pick-up which, when the plug is in the socket, makes contact with an end plate 21 on the supporting arm. Figs. 8 and 9 show examples of sockets for use with a plug made in two separate insulated parts, each of which is connected to one end of the pick-up winding. The parts 12, 13 of the plug contact respectively either with the blades 32, 32<1>, Fig. 8, or with the plunger 20 and sleeve 19, Fig. 9. For retaining the pick-up in either the operative position or rotatably displaced for needle-changing, a spring-pressed ball catch 29 may be provided in the end plate of the socket member, to engage in recesses in the pick-up casing. The supporting arm 1, Fig. 1, is a hollow bar of channel section, pivoted at 2 on a rotatable post 3. A blade spring 38 fixed to the post 3 serves partially to counterbalance the weight of the arm and pickup. Specification 314,648, [Class 40 (iv), Telephones &c.], is referred to.

Abstract: 842,120. Welding by pressure. COMBUSTION ENGINEERING Inc. May 16, 1957 [June 22, 1956], No. 15558/57. Class 83 (4). In butt - welding elongated aligned and abutted metal members by heat and pressure, the members are tied together by tie means applied at two anchor-points on the members at points spaced from the abutting ends and either allowing the heated ends of the members to expand between the anchor points due to the welding heat alone to urge the abutted ends together or applying supplementary heat to the end portion of at least one of the members to cause additional expansion thereof or applying heat to the tie means to expand them before and during the time when they are applied to the anchor points and allowing the tie means to cool and contract to additionally urge the ends together. Tube ends A, B, e.g. of carbon or chromium steel, are machined clean and provided with cardboard baffles 24 before being mounted with their ends spaced in clamps 10, 12 engaging welded projections on the tubes, the clamp 10 being fixed to the base 15 and clamp 12 being slidable on rods 16 and tie-bolts 34, 36 being provided between the clamps. A hollow water-cooled induction coil C in separable halves is placed about the spaced ends and a two-part housing 26 connected to a source of inert or other protective gas is provided to enclose the coil. Gas is supplied to the housing, the ends are abutted by tightening nuts 37 on the bolts and thereafter current at 3-10,000 kc. per sec. is supplied to the coil C to heat the ends. To obtain the welding pressure the heat conducted from the heated ends may be used to expand the tubes or electrical heating windings 38, 40 of insulated resistance wire about the tubes are energized to heat and additionally expand the tubes. One of the windings may be omitted. In another method electrical heating windings 44, 46 about the tie-bars are energized to heat and expand the bolts before the clamp nuts 37 are tightened to abut the tube ends and the bolts are cooled and contracted by blowing air thereover or by passing water therethrough if they are hollow. The heat supplied by the inductor is continued for minutes after the weld has been made. Bars may also be welded and tube end heating other than by induction may be employed and gas jets may replace the coils 38, 40. U.S.A. Specification 2,542,393 is referred to.
