Title: Means for regulating the temperature of superheated vapour
IPC: F22G5/12
Filed: 1946-10-02
Abstract: 617,463. Steam superheaters. BABCOCK & WILCOX, Ltd., and SPARKS, C. H. Oct. 2, 1946, No. 29364. [Class 123(iii)] The temperature of superheated steam, &c., from a steam boiler, &c., is regulated by interposing a condenser 6 between the outlet 4 of the boiler steam-and-water drum 1 and the steam pipe 23 leading to the superheater 24, the resultant condensate being discharged back into the steam through a drain 25 and a pipe 26 leading to a Venturi section 22 in said pipe 23. The condenser is preferably cooled by U-shaped tubes 11 the respective ends of which communicate with water inlet and outlet headers 13, 15 connected by pipes 16, 18 to the inlet and outlet headers of the normally-fitted economizer, not shown, and the flow of water therethrough is preferably regulated automatically by control of a valve 20 in the pipe 18 in dependence on means responsive to the temperature at the superheater outlet. A second or emergency drain 31 is provided on the condenser for discharging excess condensate to the drum 1. Specification 249,052, [Class 123(iii)], is referred to.

Title: Hydraulic well boring arrangement for rotary jumper method of boring
IPC: E21B4/14
Filed: 1949-11-18
Abstract: 675,988. Borehole apparatus. RINGLER, M. Nov. 18, 1949. No: 29546/49. Class 85. [Also in Group XXIII] In a hydraulically - operated well boring bit in which there is imposed on the bit 1 an intermittent rotary and percussive movement, the hydraulic motor 42 is connected to the drill pipe by a connector 48, bush 61 and connecting pipe 57 and is so positioned by the bush concentrically within a sleeve 6 so as to leave an annular passage between the cylinder 42 and the sleeve 6. Normally, hydraulic fluid passes from the drill pipe down pipe 57 through ports on a double cone valve 51, down pipes 46 and 70 to valve control apparatus 33 and out through ports 35 to act on the underside of piston 43 so causing the bit to be raised. This movement moves the control sleeve 30 relative to the member 33 to shut off the supply of fluid to the underside of the piston 43 and to permit this pressure fluid to escape through parts 34 and channel 21 to the vicinity of the bit which drops, and the cycle is repeated. The double cone valve 51 is threaded onto the pipe 57 but is prevented from rotating when this pipe is rotated because it engages with abutments in the bush 61 so that rotation of the pipe causes axial movement to regulate, as desired, all or part of the pressure fluid down the pipe 46 and through ports 54 to bypass the motor and escape via the annular passage between the cylinder 42 and the sleeve 6. A pin on the cylinder casing engages an inclined slot in the drill bit and so, in conjunction with a ratchet unit, vertical movement of the bit causes it to rotate.

Title: An improved metal section for use in the construction of motor vehicle bodies and other purposes
IPC: B62D27/02
Filed: 1937-10-29
Abstract: 504,933. Vehicle bodies; aircraft structures; furniture frames; making profile bars. MELTZ, M. Oct. 29, 1937, No. 29604. [Class 108 (i)] [Also in Groups XIV, XXII, and XXXIII] A metal section for use in the construction of motor-vehicle bodies, aircraft, furniture, &c. is of I-form and built up of two sheet-metal channels, having outwardly-projecting flanges, the head and foot of the section being constituted by sheetmetal strips having edges bent to engage the flanges of the channels which are relativelyslidable at least to one of the head and foot members to facilitate flexure of the section. After bending the parts are united, e.g. by spot-welding to provide the necessary rigidity. In a modification the channels are replaced by two - sets of separated connecting elements. As shown in Figs. 1, 2 one part constitutes the left-hand side and the head and the other constitutes the right-hand side and foot of the I-shaped section which has a core of compressed paper, millboard, or the like constituting a tacking strip 10. Each part consists of two portions comprising a flanged metal channel 11 fixed by one of its flanges 12 to an upper or lower flat metal strip 13 or 14, the other flange 17 being slidable in the bent-over edge of the adjacent strip 14 or 13. Bending is further facilitated by the provision in the channels of transverse slits 18 which extend throughout the width of one of the flanges and inwardly into the web and terminate in apertures 19 for receiving tacks for fastening fabric to the tacking strip. In modifications in which the tacking strip is omitted (1) the channels 11 lie in close proximity to each other, and (2) the two channels and upper strip form one sliding unit and the lower metal strip 14 forms the other unit. Figs. 6, 7 show a section built up of two channels 20, 21 and upper and lower strips 22, 23 there being a sliding connection between the webs of both channels and between both channels and the strips. Instead of slits for facilitating bending transverse corrugations 30, 31 are punched out in each web, and slots 40 and, if desired, lightening holes 50, provided as shown. In the construction shown in Figs. 9, 11 the channels are replaced by two sets of elements 62 each formed from an elliptical piece of steel having its ends turned up for engagement with the respective bent-over edges 61 of a pair of metal strips 60.
