Title: Improvements in or relating to telegraph systems
IPC: H04L15/18
Filed: 1924-10-16
Abstract: 245,532. Automatic Telephone Manufacturing Co., Ltd., and Harrison, H. H. Oct. 16, 1924. Automatic telegraphs. - In automatic transmission by means of a perforated strip controlling a transmitting relay, a polarized differential relay is used and its two windings are successively energized bv the successive engagement of the peckers with the perforations, so that each pecker is effective for the duration of the corresponding signal element. The Figure shows an arrangement for use with a strip perforated according to the land line Morse code. The shaft of the star wheel S driving the strip carries a metallic disc D provided with a corresponding number of teeth separated by insulating segments of the same size as the teeth. Brushes B<1>, B <2> bearing on the periphery of the disc at a distance apart equal to half the distance between two adjacent teeth are connected one through each winding of the relay PR to the contacts controlled by the peckers P<2>, P<1> respectively, and a brush B<3> connects the disc to one pole of a battery B of which the other pole is connected to the contactclosing arms C1 and C<2>. When the pecker P<1> enters a perforation the arm C<1> closes its contact to complete a circuit through the brush B<2> and one winding of the relay thus sending an impulse to line. If a dot is to be transmitted the pecker P<2> enters a perforation and the arm C<2> closes its contact to complete a circuit through the brush B<1> and the other winding of the relay, thus operating the relay to send spacing current to line after an interval corresponding to the duration of a dot. If a dash is to be transmitted this action does not occur until the brush B<1> has reached the succeeding tooth of the disc D, i.e. after an interval corresponding to three times the duration of a dot. The invention is applicable to the multiplex system described in Specification 207,354. Synchronous movements. - When there is no strip in the transmitter the relay PR is controlled by the disc D to send + and - impulses alternately to line and these may be used to maintain synchronism.

Title: Improvements relating to door operating mechanism for hopper wagons
IPC: B61D7/26
Filed: 1931-09-05
Abstract: 382,985. Locking levers. METRO. POLITANCAMMELL CARRIAGE WAGON & FINANCE CO., Ltd. and REEN, J. P., Metropolitan Works, Saltley, Birmingham. Sept. 5, 1931, No. 24964. [Class 80 (iii).] In door-operating mechanism for hopper wagons of the kind in which the operating handlever is free on the operating shaft and sets that shaft in motion through a clutch device, a clutch disc or quadrant is fixed on the shaft and has a lateral abutment for engagement by the hand-lever, and a pawl, independent of the lever, is provided to latch the disc or quadrant in the open and closed positions ; trip means are arranged between the hand-lever and the pawl to release the latter from the holding-open position automatically as the hand-lever is returned. The invention is shown applied to doors operated by toggle linkage, in which the doors open under the weight of the load when the toggle joint is broken and close under their own weight when released after discharge of the load. In the form of linkage shown in Fig. 1, the door a is connected to one end of a toggle lever pair b pivoted at the other end to the wagon frame, and the joint of the toggle levers is connected by a link g to a crank f on the operating shaft e. The shaft e is turned by a hand-lever h, Fig. 2, which is free to rotate on the boss of a clutch quadrant j fast on the shaft ; the lever engages an abutment n on the side of the quadrant j. The doors are normally held closed by a notched pawl p pivoted on the wagon frame, engaging a projection o on the quadrant j. To open the doors, the pawl is lifted and the hand-lever moved to the right, carrying the quadrant and operating shaft with it until the toggle joint is broken, when the load will force the doors open and the shaft and quadrant will run on, leaving the hand-lever free to follow without being loaded. When the doors are open, they are held in that position by a projection s on the quadrant j engaging the pawl p. To close the doors, the lever is brought back from its righthand position, and in this movement an abutment u on the lever engages a lug t on the pawl p to lift the latter clear of the projection s, thus allowing the doors to close, rotating the quadrant until it is locked in the closed position by the projection o engaging the pawl.

The distance between a probe 12 and a conducting workpiece 11 with which it forms a capacitor is measured by applying an RF signal from an oscillator 13 to the workpiece or probe, and applying the signal at the probe through an amplifier 14 and a detector 17 to a comparator 18 to which a reference signal from a generator 19 is also applied, the difference signal from the comparator being fed back to obtain a linear response. The probe may be formed by the end of a piece of insulated wire surrounded by a metal tube which serves as a guard ring. The feedback signal may be applied as indicated to a variable gain amplifier 15 following the amplifier 14, see also Fig. 2 (not shown), and in this case the distance may be indicated by a milliammeter 20 in the feedback circuit, or it may be applied to a variable gain amplifier arranged between the oscillator 13 and the workpiece, Fig. 3 (not shown), in which case the signal at the workpiece corresponds to the distance and may be measured by a valve voltmeter. In a modification of the latter embodiment, Figs. 4 and 5 (not shown), the workpiece is earthed and the signal is applied to the probe through a tuned circuit which, together with the probe electrode, is screened from earth by a screen connected to the signal-carrying lead. The signal to be fed through the amplifier 14 to the detector 17 and comparator 18 is then derived from a screened loop coupled with the inductive element of the tuned circuit.

Title: Improvements in carburetters for explosion motors
IPC: F02M7/11
Filed: 1919-10-18
Abstract: 152,206. Biquet, J., and Brut, G. F. Oct. 18, 1919. Spray carburettors.-The regulation of the primary air which draws the fuel from its container is also utilized to regulate the pressure in the fuel-container so that the delivery of fuel can be varied without interfering with the main supply of secondary air. In the form shown in Fig. 1, the nozzle g is disposed in an enlarged part of a small primary-air passage d which is connected to the top of the fuel-container by a pipe j and is provided at its lower end with a valve f. The passage d opens into the induction pipe a open to the air at b and provided with a throttle valve c. Operation of the valve f does not materially alter the depression at the restriction around the top of the nozzle g, but, as the valve is closed, the depression at the point l, and hence in the fuelcontainer, increases, and the fuel supply is therefore gradually reduced to zero. When the valve f is completely closed, the air supplied through the open end b of the induction pipe may be used for braking the engine. In the modification shown in Fig. 2, the primary air passage d<3> opens axially into the induction pipe a' and is supplied with fuel through a gap d<4> communicating with a fuel duct o fed from the float chamber i<1> through an orifice n. The passage d<3> is connected to the air space above the fuel by a tube j<1>. The supply of primary air through the passage d<3> is controlled by valves f<1>, f<2>, of which f<1> is used for regulating the air supply and f<2> for cutting off the primary air supply completely, when it is desired to use the secondary air drawn in through b' for braking purposes.
