Title: Improvements in and relating to magnetrons
IPC: H01J25/587
Filed: 1948-02-24
Abstract: 650,575. Magnetrons. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 24,1948, No. 5481. Convention date, June 4, 1946. [Class 39 (i)] A magnetron comprising an anode, a cathode and means for forming a cylindrical rotating space charge, has a plurality of resonant cavities with openings juxtaposed to an end surface of the space charge, formed in an auxiliary electrode or resonator member so that the high-frequency field and that of the anode may be independently adjusted. As shown, Fig. 3, a cylindrical anode 25 surrounds a central cathode 28, and adjacent each end is a block 23, 24 having radially extending slot-andhole resonant cavities. 35. The cavities in the block 23 are angularly displaced relatively to the cavities 35 in the block 24. The output load may be taken from both blocks 23, 24 by coupling loops 33, 34, or one loop may be used for the output, and the other may be free of load to act as a stabilizer for the operating frequency. Where the magnetron is used as an amplifier one loop may be used as an input and the other as an output. The cavity blocks form part of the magnetic circuit. In another embodiment the cavity blocks have radial rectangular cavity slots 65, Fig. 5, and alternate sector portions such as 66 or 68 are interconnected by straps 67, 69 located in a recess 70. The inner conductor of an input or output transmission line is connected to a hole 77 provided in one of the sectors. The lead to the central anode is hollow for the circulation of a cooling fluid. The resonant cavities may be formed by radially extending vanes and may be distributed asymmetrically about the central axis of the magnetron. The magnetron may be operated as a reactance device. Specifications 423,897, 424,746, [both in Group XXII], and 635,479 are referred to.

Title: Improvements relating to towing and release mechanism
IPC: B64D3/00
Filed: 1943-04-06
Abstract: 572,780. Rope fastening and releasing devices. MALCOLM, Ltd., R., and LOBELLE, M. J. O. April 6, 1943, No. 5506. [Class 44] [Also in Group XXXIII] A towing and release device, particularly for aircraft towed initially by two tug craft one of which is disconnected when the aircraft has become airborne, comprises a coupling device in the towing cable which passes through a plug member h on a junction member d, connected to the aircraft to be towed, a relaxation of the pull by one of the tug craft causing the cable to be drawn through the junction member by the other tug until the member h engages and releases the coupling, further movement through the junction member of the cable attached to the remaining tug craft being prevented by an enlargement on the cable which engages the end of the plug member. The device may be used in towing marine vessels when it is desired to release one tug at short notice. In one form, the coupling comprises a casing 20, Fig. 5, attached to the cable from the auxiliary tug craft, and adapted to receive a spigot u attached to a cable g which passes around a sheave v, Fig. 8, in a junction member d connected to the towed aircraft by a forked bridle. This cable is connected at its other end to the main tug craft. A plug member h through which the cable passes is pivoted to the member d. Normally an enlargement 24 on the spigot u is engaged by two pivoted and statically balanced pawls 21 urged into engagement with the enlargement 24 by springs 23. To release the auxiliary tug craft it is throttled down, whereupon the main tug draws the cable g around the sheave v until the plug member h enters the lower end of the casing 20 and forces apart the pawls 21. The casing 20 then falls away and the spigot u remains in contact with the member h. A stop on the other leg of the cable prevents it from being drawn too far over the sheave v in the other direction. Terminals 14, 15, the latter insulated enable electrical connections to be effected across the coupling. The ends of the cables attached to the two tug craft are readily releasable as also is the bridle connected to the towed aircraft. In another form, Fig. 10, the casing of the coupling is in two hinged parts having ledges 33 for retaining a disc 34 secured to the end of the cable g, and grooved projections 36 for engagement by the undercut head of a member 37 This member has a sliding thimble 40 urged by a spring 41 against the undersides of the projections 36. When the plug member h engages the lower end of the member 37 the latter is moved out of engagement with the projections 36 and the hinged halves of the casing are forced apart to release the disc 34. Simultaneously the thimble 40 is moved by the spring 41 to close the undercut surface of the head 37 to prevent the projections 36 from re-engaging the head 37 as the casing falls away.

Abstract: 513,899. Cements, mortars &c. WALLACE, N. E., LEFEBURE, V., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 22, 1938, No. 5507. [Class 22] The strength and hardness of cements comprising blast furnace slag, calcium sulphate and Portland cement clinker are improved by allowing the cement to set in the presence of additional lime derived from a liquid medium in contact with the setting cement or from a limecontaining or lime-producing substance other than lime itself or Portland cement clinker, added to the mix. The fineness of the cement is preferable such that at least 60 per cent. by weight of the slag, at least 50 per cent. of the Portland cement clinker and at least 60 per cent. of the final cement comprises particles not exceeding 30 microns in diameter, as described in Specification 513,897. The lime may be added by curing the setting cement in lime water, or by adding crushed sand-lime bricks or crushed calcium sulphate (plaster of Paris), containing 10-20 per cent. of lime to the cement.

Filed: 1940-03-27
Abstract: 542,210. Knitting - machines. JACQUARD KNITTING MACHINE CO., Inc. March 27, 1840, No. 5534. Convention date, May 23, 1939. [Class 74 (ii)] Continuous jacquard paper rolls supported on co-axial drums 14, 14a are disposed in groups around the stationary needle cylinder of a knitting machine. Each group corresponds to a single old-style jacquard roll with its operating mechanism. The framework structure of each unit comprises a radial bracket 30 integral with a pad or base 31. Preferably, a shaft 32 extending through the bracket 30 carries two independently rotatable drums 14, 14a. Enlargements 33 and screws and washers 34 prevent the drums from slipping off the ends of the shaft 32. The drums are driven by a single shaft 35, through spur and Geneva wheel gear. Adjacent shafts 35 are driven one from another by bevel gears 35a. To render the pattern mechanism operative or inoperative at will, the pin wheels 38, 39 for driving the Geneva wheels 36, 37 are mounted so they can be pushed along their common shaft 40 into or out of engagement with the wheels 36, 37. To keep the pin wheels properly timed, the faces of their driving gears 41 are made long enough to drive them in all positions. Each pattern strip of paper serves a group of couplers 11 and is perforated to permit feelers on the couplers passing into slots 15 of the drum. When feelers are engaged, the corresponding couplers 11 are carried forward into the path of revolving cams 16. Their inner ends are thus depressed while corresponding jacks are raised to select the corresponding needles.
