Title: Ejector Method of and Apparatus for Compressing Elastic Fluid.
Inventor: MELLERSH-JACKSON WILLIAM JOHN
IPC: F04F5/18
Filed: 1918-04-15
Abstract: 124,912. Jackson, W. J. Mellersh-, (Wheeler Manufacturing Co., C. H.). April 15, 1918. Aspirating-apparatus, ejector. - Relates to steam-operated vacuum-producing air ejectors of multi-stage type, and consists in so proportioning the total throat area of the nozzle or nozzles in the first stage to the like area in the second stage that in the first stage there will be consumed more than five per cent of the total motive fluid of both stages, from which results a ratio of compression in the first stage equal to, or greater than, the ratio in the second stage, provided the initial pressure of the fluid to be compressed remains within a certain range, which, in the example given in the Specification, is from 0 to 5 inches of mercury absolute, when the final pressure to be produced is 30 inches, for discharge to the atmosphere. Fig. 2 shows apparatus wherein the inducing-fluid, such as steam, enters by an opening e and, passing through a number of nozzles N each with throat T, draws air &c. from a suction inlet g and forces it through a diffuser h into a chamber i, which may contain a condenser for the steam. From this chamber, the fluid to be compressed passes on to the suction inlet and is compressed by means of the second-stage ejector, comprising nozzles N<1> with throats T<1>, diffusers h<1>, delivery k, and steam intake e<1>. The construction, of the ejector in either stage is not material to the invention, for instance a construction such as is described in Specifications 113,798 and 114,134 may be employed, or the arrangement of nozzles N in the first stage may be as shown in Fig. 4, wherein there are two circular series, and a central nozzle, all with throats T. Preferably, the first-stage nozzles increase in length towards the centre, whereby greater steadiness of suction-inlet pressure is obtained under varying load. In all cases, the proportion between the throat areas is subject to the above-mentioned limitation.

Title: Improvements relating to unit heaters having electrically driven fans
IPC: F24H3/04
Filed: 1947-03-10
Abstract: 622,064. Screw fans. MATHER & PLATT, Ltd., and BARCLAY, S. F. March 10, 1947, No. 6600. [Class 110(i)] An electrically driven fan comprises at least one thermostatic switch heated by a heating element connected in the circuit of the driving motor and mounted in the path of the air entering the fan so that it is normally cooled sufficiently to prevent its operating. If the motor fails to start, the thermostat operates to interrupt the motor current. For a three-phase motor, Fig. 2, a thermostat e and its heater element f are connected in series with each of two of the phases. If the motor is of the single phase type, one thermostat is sufficient. The thermostat comprises a bimetallic disc g, Fig. 3, which breaks the circuit with a snap action. The thermostat is subsequently re-set by hand. A radiator within the fan casing heats the air as it leaves.

Title: A device for protecting the fuse of bombs suspended from aircraft
IPC: F42C19/04
Filed: 1927-03-11
Abstract: 267,920. Remondy, L. E. March 19, 1926, [Convention date]. Projectile fuzes.-The percussion fuze A of a bomb intended to be dropped from aircraft is enclosed out of action by means of a casing in two longitudinal halves C, D provided with a flexible belt E with end lugs E' held between the jaws f of a claw F flexibly attached to the aircraft. If the claw F is left attached to the aircraft, it is pulled off the lugs E' when the bomb is dropped; the belt E then springs open and detaches the casing C, D from the fuze, which is then armed for action on impact. But if the claw F is disconnected from the aircraft, it drops with the bomb undetached from the lugs E<1>, and the fuze cannot act on impact. More over, the edge of the disc G carried by one of the halves of the casing C, D becomes bent by the impact, as shown in Fig. 2, and prevents and subsequent accidental opening of the casing in spite of the separation of the claw F on the shock of impact. Such accidental opening is further prevented by a rib c<1>, d' on the casing C, D, which is driven by the impact into the material of the fuze body B. In a modification, the front end of the casing C, D is extended to form a hook for the suspension of the bomb. Specifications 233,262 and 235,161 are referred to.

Title: Improved method of, and means for use in, welding by the electric arc process
IPC: B23K9/14
Filed: 1940-04-17
Abstract: 537,164. Uniting by fusion. PETERS & CO., Ltd., G. D., and NEEDHAM, R. April 17, 1940. Nos. 6922 and 7310. [Class 83 (iv)] In a method of electric arc welding a flux coated electrode is placed lengthwise in the space enclosed by the walls of the weld metal channel and also by the walls of a longitudinal groove in a backing bar of heat conductive non-welding material which lies against the work parts on either side of the channel and excludes air from the arc and permits escape of gas, the welding proceeding automatically as the welding rod is consumed by melting of its metal core by the arc. In butt welding parts 1, 2, the edges of the parts may be shaped to provide a V or semicircular channel 5 which may be closed or open at the base and a flux coated electrode 6 is placed in the channel and enclosed at its other side in a V-shaped groove in a copper backing bar 7. One end of the electrode is bared and is secured in clamping jaws 10 connected by a conductor 9 to one terminal of an electric circuit and secured to a peg 12 mounted in but insulated from, the bar 7. The arc is struck by a carbon electrode 14 mounted on a pivot 15 secured to, but insulated from, the bar 7. A switch may be provided which may operate to cut off the current automatically when the arc approaches the end of the electrode, being associated with a thermostatically actuated trip means responsive to rise of temperature resulting from proximity to the arc. In forming corner joints, lap joints or T joints, Fig., 8, between plates 1, 2, the bar 7 is substantially L-shaped to provide one side of the enclosed space, the other side being formed by the angle between the parts. Recesses of different sizes may be made in opposite comers of the bar. In another form the recess may formed with lips 16, Fig. 9, for retaining the electrode therein in which case the electrode may be passed through the recess before the bar is applied to the work. The outer surfaces of the bar may be longitudinally grooved or ribbed, filled or checkered &c. to dissipate the heat to the atmosphere and the surfaces which are in contact with the work may be grooved longitudinally to improve the gas seal between the bar and work. In butt welding operations a second heavy bar may be disposed beneath the joint to support or prevent the spread of metal at the underside of the joint and assist in dissipating heat therefrom. The backing bar and/or the underbar may be hollow and water cooled. When making a T- joint dislocation may be prevented by welding along both sides of the joint simultaneously the arcs travelling in the same or opposite directions. Tubes may be butt welded to each other by using curved backing bars and electrodes.

Abstract: 854,720. Code telegraphy. LENKURT ELECTRIC CO. Inc. March 3, 1959 [May 12, 1958], No. 7272/59. Class 40(3). [Also in Group XL(c)] In a diversity communication system the same signals are transmitted on at least two separate channels and a delay is introduced in one channel at the transmitter and a similar delay is introduced in another channel at the receiver, whereby the signals in the separate channels at the receiver are brought into time coincidence. In this way the system provides time diversity in addition to channel diversity. As shown a common input pulse signal is supplied at 11 to a pair of transmitters 12, 13, the transmitter 12 being connected direct to a transmission circuit 30 and the transmitter 13 being connected via a delay device 14. The circuit 30 may be a radio or cable link, and each transmitter transmits on a different carrier or sub-carrier frequency. Alternatively, the two carriers may be of the same frequency and other distinguishing characteristics used, e.g. one channel may be the upper sideband and the other channel the lower. At the receiving terminal the receiver 22 through a delay device 21 receives the modulated wave from the transmitter 12 and the receiver 23 receives the delayed modulated wave from the transmitter 13, the outputs of the two receivers being supplied to a known diversity combining circuit 24 which may combine the two signals or select the better one. The delay devices may consist of a magnetic tape recorder having the recording and reproducing heads spaced apart in the direction of tape movement. The transmission circuit may consist of two separate lines. The arrangement may be applied to a three-channel diversity system with different delays in each channel. The inclusion of the arrangement in a multiplex system is described, Fig. 4 (not shown).
