[Class 83 (iv)] In arc-welding two parts of a structure such as two plates or a plate to a stiffener behind it, particularly in ship construction, the parts, then immovable, are held with their surfaces in contact and overlapping, but not pressed together and an arc is struck by an electrode, the arc passing through the two parts where their surfaces are in contact, the electrode then being moved over the surface of the adjacent part to form a trench of molten metal of such depth as to extend through one part and into the other part behind it, the trench following a straight or curved line and being filled by additional weld metal as the electrode is moved along the work. The trench is at a distance from the edges of the parts, one run of weld thus replacing the two runs required in fillet welding. The lapped parts A, B, which are held with their surfaces in contact without applying more pressure than is necessary to maintain them in correct position may thus be welded by an arc struck through the two plates to form a crater C which is filled with molten weld metal D, the arc being moved along to form a trench filled with weld metal. A plate G may be similarly welded at L to a stiffener with a single lateral flange H<1> or With a thickened edge portion. According to the Provisional Specification, the joint may consist of a series of separate craters filled with weld metal. Referenee has been directed by the Comptroller to U.S.A.

Abstract: 1,048,622. Concentric tube heat-exchangers; hot water boilers. P. LECLERCQ. May 10, 1963 [May 11, 1962; Feb. 25, 1963], No. 18530/63. Headings F4A and F4S. A heat-exchanger comprises a plurality of coaxial cylinders O, adjacent pairs of which enclose annular spaces 1-11, at either end of which are fluid-distribution chambers each divided into first and second chambers containing inlet and outlet ports, such that a heating fluid flows through alternate annular spaces and a fluid to be heated flows through the other spaces. In the embodiment shown in Fig. 1, the cylinders O engage with circular grooves 12 provided in two perforate plates 13 and 14. Externally of these plates are cylinders 15, 16 which similarly engage the plates 13, 14 and also endplates 17, 18; the lower part of the latter containing fluid inlets 19, 20 and the upper part, fluid outlets 21, 22. Opposite the inlets 19, 20 are fixed deflectors 45, 46 on the partitions 13, 14 respectively. The spaces between the plates 13 and 17, and 14 and 18 constitute the distribution chambers. The cylinders 15, 16 are circumferentially interrupted, alternate annular spaces being blocked from the inlet 19 and outlet 21; and the other annular spaces being blocked from the inlet 20 and the outlet 22 by radial partitions 23, 24 (Fig. 2, not shown). The annular spaces contain helical dividers 49, 50. The cylinders 0 have annular rings 60 welded to them (Fig. 4, not shown) which provide a seating for packings 61 between these rings and ridges 13a on the plate 13. Sealing is similarly effected with the plate 14 and between the cylinders 15, 16 and plates 13, 17 and 14, 18, respectively. The end plates are constrained towards one another by means of a tie-rod 36 and nuts 37, 38, 39. A frusto-conical cap 106 may be placed between the end plates and the outer nut (Fig. 3, not shown). The invention may be used as a vertical boiler (Fig. 5, not shown). The burner is positioned at the top of the central cylinder down which the combustion gases pass to a smoke box 204, lined with refractory material or water-jacketed, from which gases are deflected upwards through alternate spaces. The water inlet being at the lower end of the boiler, both the water and the exhaust gas outlets are positioned in the upper distribution chamber. The single connecting rod is replaced in this embodiment by four rods passing through the innermost annular space through which water flows. In another embodiment (Fig. 6, not shown) the longitudinal dimension of the coaxial cylinders increases towards the axis of the heat-exchanger, the ends of the cylinders abutting on to a frusto-conical shaped plate 63 comprising rings 64-68 which contain vents 71-75 respectively. The vents provide passages for the fluids between the inlets and outlets and the annular spaces, adjacent vents being offset 180 degrees on opposite sides of two radial partitions 76-77 (Fig. 8, not shown). Sealing between the cylinders and the frusto-conical plate 63 is effected in similar manner to that described above.

Title: Improvements in integrated mica and method of making the same
IPC: H01B3/04
Filed: 1946-06-20
Abstract: 615,489. Mica. HEYMAN, M. D. June 20, 1946. No. 18610. [Class 70] Sheets of mica are prepared by splitting pieces of mica into thin laminae while immersed in a medium such as methyl alcohol or distilled water which prevents contamination of the surfaces, and forming the laminae into a stratified sheet while still immersed in the medium. The mica is fed from a hopper 10a to a screen 12a where loose pieces and dirt are removed and thence to a cleaner 13a comprising a rapidly-reciprocating rubber-faced plunger 36 and a metal-faced platen supported on a rubber block 34 through which pins 33 project, so that the mica is subjected to rapid compression and release and flexure to cause removal of stones and other foreign matter. After passing over a screen 14a, the mica is washed and dried and fed to a disintegrator 17a having a series of vertically-communicating chambers of diminishing size and of ellipsoidal shape. Jets are arranged in the walls, in staggered relationship on opposite sides, and act to drive the mica around the walls and to split it. The jets are preferably supplied with pulsating liquid under the control of pumps 19a. The mica gradually floats upward and is finally delivered to a flotation tank 61 where any remaining foreign matter is deposited in the sump 62 and any large pieces of mica fall into a sump 64 whence they are returned to the disintegrator 17a. The liquid carrying the mica flakes passes over a magnetic roll 22 which acts to remove iron-contaminated flakes and the remainder passes to rotating screens 23, 24 where the flakes are graded and separated from the liquid which is recirculated. The flakes are passed into rotating fine-mesh screens wherein they are formed into cylinders by centrifugal action. The cylinders are cut, flattened in a press 27, preferably by vacuum, in an extractor 28 and, if desired, impregnated in a tank 29 and ground on a surface finisher 30.

Title: Fluid bearings
IPC: F16C32/06
Filed: 1950-07-26
Abstract: 676,925. Fluid bearings. GERARD, P. L. J., and GENDRON FRERES SOC. ANON. July 26, 1950 [Jan. 24, 1950], No. 18694/50. Class 12 (i). In a fluid bearing comprising two concentric members, the pressure fluid (e.g. compressed air) is distributed to circumferentially spaced pressure zones between the two members through suitable nozzles or throttlings, the pressure zones each having a separate inlet, a system of grooves of small cross-section to facilitate distribution of the pressure fluid and outlet channels separating them from their neighbours. A groove system suitable for distributing the pressure fluid comprises an inlet nozzle 14, Fig. 9, grooves 15, 15a and outlet channels at each side. In modifications of the groove form, Figs. 11 to 15, not shown, the system is constituted by (a) crosses, (b) a cross having the ends of its two grooves joined by further grooves, and (c) a rectangle with two of its opposing sides joined by a mid-groove. A bearing according to the invention comprises peripheral feeding zones 2A ... 2E, Figs. 16, 17, 18, feeding ducts 3, longitudinal outlet channels 4a, an inlet 5 for the pressure fluid, an annular supply chamber 6 and a filter 7. A series of annular chambers I ... IV surround the bearing, groove II communicating directly with the chamber 6. The feeding zones are connected to the chambers I ... IV, the lower feeding zones 2A, 2B being connected in parallel with the annular groove II which is fed direct from the chamber 6; zones 2A, 2B are thus fed at a high pressure, in order to overcome the effect of gravity. The other feeding zones are fed in series with zones 2A, 2B, the pressure fluid evacuated from zone 2A through the channels c, d feeding zones 2C, 2D respectively via chambers I, III; similarly zone 2B feeds to zones 2D, 2E, and so on, until the pressure fluid is finally evacuated through passages a, b which open directly outside at 18, 19. A flange 23 on the shaft is prevented from coming in contact with the bearing by the leakage of fluid from the opening 19. In a modification, the invention is applied to a thrust and pivot bearing adapted to carry a vertical rotor. In a further modification, a shaft is supported by a bearing surface, containing pressure zones according to the invention, which covers only a portion of its periphery. A form of pressure zone constituted by jets alone, viz. with neither pressure chambers nor groove systems, also is described. A further form of pressure fluid bearing is disclosed similar to that of Specification 642,891.

To prevent the transmission of forces from the road wheels to the steering wheel of a vehicle employing rack and pinion steering gear, a frictional brake is responsive to the relation between the direction of rotation of the pinion and the direction of the tooth pressure between the rack and pinion. The pinion spindle d is sup-, ported by a single bearing e remote from the rack b and the lateral thrust is resisted by one of two fixed friction pads k<SP>1</SP>, k<SP>2</SP>, Fig. 2, which are parallel with the two possible lines of tooth, pressure. The pads are engageable respectively with two collars g loosely mounted on the spindle d between two collars f which are splined to the spindle and abut respectively the pinion c and a sleeve m, contacting the bearing e. Adjacent faces of the collars g are provided with tapering grooves containing balls j, or other wedging means, and the collars are urged apart by a torsion .spring. When the pinion c rotates, in either direction, to drive the rack b the tooth pressure is in such a, direction that the appropriate friction pad is engaged to hold stationary that collar g causing contraction of the pair of collars. When, however, the rack drives the pinion, the two directions of tooth pressure corresponding to the two directions of rotation are interchanged, so that the pair of collars g is expanded to bear on the collars f and brake the spindle d. Specification 615,096 is referred to.
