Title: Improvements in and relating to circuits for electric relays
IPC: H01J40/14
Filed: 1933-01-21
Abstract: 391,742. Valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Cockrell, W. D. ; 1, Rugby Road, Schenectady, and Juchter, P., 349, Glen Avenue, Scotia, both in New York, U.S.A.) Jan. 21, 1933. No. 2030. Convention date, Jan. 21, 1932. [Class 40 (v).] The output of a valve 8, whose plate circuit is energized by unrectified alternating current through the trans former 2, is con trolled by a photo electric cell or other rectifying resistance 7. Only when the latter is in the operative condition is the output relay 20 energized, and in order that this energization may be effected at an early phase in the " positive " half of the A.C. supply a resistance 12 of 10 or 20 megohms is inserted between the grid 17 and capacity 11 which may be 0À0002 mF. The " positive " half-cycle is that in which the plate 24 of valve 8 is positive. During the negative halfcycle, grid 17 is charged through point 21 and condenser 11, and grid current flows so as to charge the plate 11a negatively ; hence the valve 17 becomes blocked as long as the photoelectric cell 7 is dark. When the cell 7 is illuminated, however, the condenser 11 discharges through the cell and the now positive point 25, and the grid 17 becomes positive ; during the time when the plate 24 also is positive, but in order that the grid 17 may quickly acquire its positive charge in spite of the negative charge on the condenser, the high resistance 12 is inserted and the periods during which plate and grid are positive are thus caused to overlap to a greater extent. In a modification, Fig. 2 (not shown), the point 18 is connected to the middle point of winding 6. Where the leads 9, 10 have large inherent capacity 22, 23, the grid current has to be limited bv a resistance 19.

Title: A new or improved hose end fitting
Inventor: METSOM WALTER ARTHUR
IPC: F16L33/207
Filed: 1959-01-21
Abstract: 939,423. Hose end-fittings. OIL FEED ENGINEERING CO. Ltd. Nov. 5, 1959 [Jan. 21, 1959; Feb. 27, 1959], Nos. 2325/59 and 7039/59. Class 99(1). An end fitting applied to a flexible hose of rubber or like material comprises an insert H which can be fitted into the bore of the hose E and a ferrule G fitted over the outer surface of the hose. The insert H has a plurality of peripheral grooves C of rectangular cross-section the depths of which are more than one third of their width and into which the rubber of the hose is forced by contraction in the diameter of the ferrule e.g. by swaging so that the rubber constitutes a plurality of rings sealing against leakage along the meeting surfaces of the hose and the insert. As shown, the ferrule has near its outer end a groove F leaving a reduced thickness of metal which registers with a projection A on the insert: the ferrule is also counter bored at G<SP>a</SP> in line with a tapered part D of the insert. The outer covering of rubber is removed from the end of the hose to a point beyond the grooves C. When the ferrule is swaged down from the condition shown in the lower half of the drawing to that in the upper half, the inner layer of rubber will flow into the grooves C forming rectangular section sealing rings and the reduced thickness of the ferrule left by the groove F will wrap itself about the projection A and clamp the reinforcement. The projection A may be part circular cross-section or " square " on the left-hand side to lock the reinforcement behind the projection. The groove F in the ferrule may be in the internal surface. When the reinforcement is of a textile nature and it is undesirable to expose it the ferrule is reduced in diameter at a zone in register with the grooves and to a generous radius to avoid setting up a sharp bend in the reinforcement. This construction can also be used with a hose in which the outer layer of rubber can be removed. The latter is replaced by a sleeve of soft metal which, when the ferrule is reduced in diameter, will flow and embed itself into the reinforcement and peripheral grooves formed in the internal surface of the ferrule.

Filed: 1948-01-26
Abstract: 639,287. Magnetic amplifiers. ELLIOTT BROS. (LONDON), Ltd., and HAWKES, H. D. Jan. 26, 1948, No. 2343. [Class 40 (iv)] A magnetic amplifier for producing an alternating current in quadrature with an exciting potential but leading or lagging according to the polarity of a controlling D.C. potential comprises an input transformer 6 supplying A.C. to two parallel paths, one of which includes a variable choke 10 and the other a saturable reactor having a magnetizing coil 9, and a control winding 8. The choke 10 is adjusted so that with no control potential on the winding 8 the currents in the primaries 1, 2 of transformer 3 are equal and opposite. The application of a control potential on winding 8 either reduces or increases the magnetization of the reactor core resulting in an output current as above. In a modification, Fig. 2 (not shown), the choke 10 is replaced by a saturable reactor arranged so that its magnetization is conversely affected by the controlling potential. The harmonic content in the output may be reduced by tuning the secondary 11 of the output transformer. Specification 597,410, [Group XXXV], is referred to.

[Class 103 (i)] Vehicle brakes are arranged to be applied by two hand-levers disposed side by side on a common pivot and acting at different leverages upon a brake rod or the like through common floating lever or through a common chain and floating pulley or sprocket device. According to Fig. 1, hand-levers 20, 26 for normal and emergency application of the brakes, respectively, and mounted on a common shaft 27 are connected at their lower ends 25, 21<SP>1</SP> to a floating lever 22 through a link 21 in one case. The lever 22 is connected to a brake-operating rod 24 at a point 23 that is nearer the lower than the upper end of the lever and since the lower arm of lever 26 is shorter than that of lever 20 whereas the upper arms of these levers are equal, the lever 26 acts upon the rod 24 through a greater leverage than the lever 20. The brake may be applied by the lever 20 and the application be then increased by operation of the lever 26. A stop 48 may be provided on the lever 20 or other part to prevent initial application by the emergency lever. In a modification, Fig. 5, normal and emergency hand-levers 30, 31 mounted on a common pivot 32 are connected at their lower ends respectively to the ends of a chain 33 passing around a sprocket wheel 34 pivotted at 35 in a fork 36 on a rod 37 connected to the brakes and slidable in a guide 38. A suspension link for the sprocket may be substituted for the guides 38. The broken lines 34a, 34b indicate the position of the wheel 34 after operation first of the lever 30 and then of the lever 31 to the positions 30a, 30b respectively.
