Filed: 1924-09-25
Abstract: 225,184. Sulzer FrÞres Soc. Anon. Nov. 19, 1923, [Convention date]. Valve gear.-A spraying valve c, which is pressed on to its seating by a spring m acting through a bell-crank lever l, is surrounded by a yielding piston f loaded by a spring c, which normally assists to maintain the valve c or its seating, when a valve g on the upper end of the piston f is in contact with a collar on the valve c. Fuel is supplied by a pump through the passage a and lifts the piston f against the pressure of the spring e until the pressure of the spring m is removed from the valve c by the action of a cam h. When this occurs, the valve opens and ejection takes place under the pressure of the spring e, until the member g on the upper portion of the piston f engages the collar on the valve c and thus closes the valve. The cam h is so shaped that the pressure of the spring m is not operative until the valve has been closed by the spring e.

Abstract: 351,290. Drum controllers; electromagnetic switches. PEDRAZZO, G., 3 bis, Via Cernaia, Biella, Italy.. July 28, 1930, No. 22679. Convention date, July 27, 1929. [Classes 38 (iii) and 38 (v).] A controller such as for multiple power electrical machines as described in Specifications 313,501, [Class 38 (iii), Electric motor control systems &c.], and 344,371, comprises an armature g, Fig. 1, secured to the controller shaft e and attracted to various positions by electromagnets E, only one of which can be energized at a time, and a device is provided to de-energize the attracting electromagnet as the armature is displaced theretowards. The control circuits are shown in Fig. 4. Relays D are traversed by current proportional to that in the machine windings 1 .. 15, but only one relay is free to move the others being held in their midpositions by a cam ring S, Fig. 6, secured to the shaft e. Change of current through the relay that is free to move causes it to engage contact o or p and thereby energize one or other of the electromagnets on either side of the position occupied by the armature g. As the armature moves towards the adjacent electromagnet, the cam ring S centres the relay that initiated the action and frees an adjacent relay. Each relay serves for two powers by means of a distributer W which selects which of two diametrically opposite electromagnets shall be energized by the relay. The distributer also, by engaging contacts X in the first four positions of the controller, short circuits resistance in series with the windings of the relays D and so alters their sensitivity, thus adapting the device for star-delta grouping of the windings of the machine. The relays are provided with dashpots and dead-centre spring contacts. The distributer is designed to prevent energization of electromagnet EI, when the armature is opposite electromagnet EVIII and vice versa, so as to obviate the controller being moved from one extreme position to the other without passing through all the intermediate positions.

Filed: 1920-08-03
Abstract: 149,917. Squier, G. O. Aug. 3, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Aerials; duplex wireless signalling; directive wireless signalling.-With a suitable counterpoise, capacity, living vegetable organisms, such as trees &c., are used as aerials for the transmission or reception of wireless oscillations. Such an aerial ssytem may be used for directive reception and for the simultaneous transmission or reception of a plurality or messages, consisting of damped or undamped waves. In the direc. tive receiving system shown in Fig. 1, the tuned circuit 6 is connected in series with a metallic nail 4 driven into a tree at a point approximately two-thirds of the height of the tree above the ground, and with a counterpoise 10, consisting of one or more insulated wires 11, extending rectilinearly in the direction of the transmitting station. Preferably a number of counterpoises are employed radiating in different directions, with a switching-device for connecting the circuit 6 with the counterpoise most closely parallel to the desired direction. The circuit 6 is coupled to another tuned circuit comprising two rotating parallel loops 30, 31, detector 3, condenser 2, and a switch 18 for reversing the direction of the loops 30, 31 with respect to one another. When the loops 30, 31 are rotated to lie in the plane of the transmitting-station, by means of the switch 18, currents in them may be made to oppose and neutralize one another or to augment one another for detection and amplification by the apparatus 3. Fig. 2 shows the invention applied to the simultaneous reception of a plurality of messages. The nail 4 is connected to a conductor 38, which is provided with individual switches 39, 40, 41, leading to the receiving sets. The counterpoise 11 is connected to another bar 42 connected to the receiving sets. By means of the switches any or all of the receiving sets may be brought into operation. In Fig. 2, two receivers for damped waves 50, 62, and one for undamped waves 63 are shown, the switches being arranged for the reception of damped and undamped oscillations. The resistance of a tree serving as an aerial is greater than a metallic antenna, and to obtain best results it is desirable to modify the resistance or alter the design of the receivers. In applying the invention to the simultaneous transmission of a plurality of messages, a similar arrangement is used, the receiving sets 50, 62, 63 being replaced by transmitters of damped and undamped oscillations.

Abstract: 782,020. Reservoir pens. MABIE, TODD & CO.. Ltd. Nov. 4, 1955 [Aug. 6, 1954], No. 22952/54. Class 146(3) In a reservoir pen, the barrel is provided with a panel 3 hinged longitudinally in the wall thereof, whereby access may be gained to the interior of the barrel, e.g. for operation of a presser-bar. As shown, the barrel 1, Fig. 2, has a reduced portion 9 carrying a threaded part 10 which receives a sleeve 2, the mating ends of the barrel and sleeve being chamfered at 11 and 12 respectvely. An opening 13 in the barrel 1 receives the panel 3 having lugs 15 which co-operate with a lug 14 on the barrel 1 and a pin 4 to form a hinge. The panel 3 is locked in the closed position by a chamfer 11a engaging the chamfer 12, the panel being unlocked by unscrewing the sleeve 2 to permit opening by a tension spring 5. A presser-bar 7 having frictional engagement with the rear end of the barrel is exposed for actuation when the panel 3 is opened. Alternatively, the presser-bar may be a flat metal strip attached to the sac and dependent on the resiliency of the sac for its return movement. In a modification; the rear end of the presser bar is held between a screw 8 and a spring, not shown, may be positional between the screw head and the barrel end. In this case, the threaded connection between the barrel and sleeve is dispensed with to perinit rearward sliding of the sleeve which causes release of the panel. In a further modification, a groove in the barrel receives a ring of wire which forms a hinge pin for the panel, the end of the wire being bent to act as a spring for opening the panel. In another construction, the panel is attached by a spring and catch to a metal liner extending the whole or part of the length of the barrel, the panel having a synthetic plastic cover similar to the barrel. In a further construction, the panel 3, Fig. 12, has a flange 8 engaging a lug 16 on the presser-bar 7 to form a latch. The presser-bar 7 engages a screw 10 screwed in a cap 2. When the cap 2 is unscrewed the presser-bar is moved rearwardly against a spring 11 to release the panel 3. The panel 3 may be extended in length to permit insertion of an ink cartridge or ball-point pen refill, the presser-bar being dispensed with in this case.
