Abstract: 941,124. Electric selective signalling systems. THERMAL SYNDICATE Ltd. July 6, 1962 [July 7, 1961], No. 24611/61. Heading G4H. A dimension of an object 2 is measured by viewing the object with a television camera 1 and using the signals derived from one line scan or one frame scan to obtain a count representing the desired measurement. In the embodiment shown, one line scan is selected by gate 4 and pulses from a source 6 are fed to a counter 7 through gate 5 over the period in which the selected line scan is 100% "white". The actual position at which the measurement is performed may be indicated on receiver 3 by suppressing the signal from camera 1 during the appropriate line scan. In another embodiment, one line scan is selected as above, but radio-frequency pulses are obtained directly from camera 1 over the period in which the object 2 is being scanned. In a further embodiment, the object 2 is measured in a direction which is perpendicular to the line scans, and the number of "white" line scans in one frame scan is counted.

Title: Improvements in and relating to self dischargers with a bottom which can be tilted to both sides
IPC: B61D7/10
Filed: 1921-09-17
Abstract: 171,672. Krupp Akt.-Ges., F. Nov. 15, 1920, [Convention date]. Hopper wagons.-Relates to a self-discharger such as a railway wagon having a bottom which can be tilted to either side and which is in a force closure pivotal connection with the side walls, which connection is automatically released on the tilting movement of the bottom on the discharge side, while on the opposite side the connection is maintained and transmits the movement of the bottom to the side wall which is situated on this side and is movable relatively to the bottom. Fig. 1 shows in transverse section a wagon ready for loading, and Fig. 2 a corresponding section when discharging to the right. Each side wall E is connected to the bottom C by a separate gearing H, G, G<1>, J, k', k<3>, M, b<2>, b<1>, D, which, when the tilting movement of the bottom takes place to one side produces between the bottom and the side discharge wall E a positive connection acting in the direction of an outward movement of the side wall and, when the tilting takes place toward the other side, leaves the same side wall unacted upon. Each side wall E is connected at the top by a link F pivoted to the end wall A<1> of the vehicle and in the loading position rests in a bearing a<4>. The lower end e<1> of the wall is in a force closure pivotal connection with the edge c<2> of the floor by means of the link H which is connected to a bell crank lever G, G', pivoted to the floor C. Two longitudinal shafts K, situated on opposite sides of the centre line of the vehicle, each have opposite cranks k<1>, k<3> connected to them which are operated by a hand-wheel k<2>. Two brackets on opposite sides of the longitudinal centre line each carry opposed cranks b<1>, b<2> on a pivot B, their movement being limited by a stop a<3>. When the left hand-wheel k<2>, as shown in Fig. 2, is turned, it operates, through crank k<3>, the link M, opposed cranks b<2>, b<1>, and the link D which is pivoted to the right-hand side of the floor and can only move inwardly away from the stop c<1>. The floor tilts to the right about the pivot of the left-hand links D and b<1>, the right-hand side wall opening outwards by means of the link H, whilst the left-hand side wall remains in contact with the floor, as the axis of the pivot of the right-hand links G<1> and J coincides with the axis of the pivot of the left-hand links D and b<1> so that the left-hand link H does not move relatively to the floor. If the right-hand wheel k<2> is operated, the load is discharged to the left in a corresponding manner.

Title: Improvements in power actuators or servomotors
IPC: B60T13/24
Filed: 1926-10-07
Abstract: 260,967. Bragg, C. S., and Kliesrath, V. W. Nov. 5, 1925, [Convention date]. Pneumatic relays.-A vacuum servomotor described as operating a brake has a vacuum maintained on both sides of the piston and is connected to the suction pipe by reduced passages of less cross-sectional area than the air or other pressure pipes. A check valve is arranged in the suction pipe connection. The servomotor 1 is connected by a pipe 62 to the intake manifold of an internal-combustion engine, the spring-controlled brake lever 88 being connected to a central valve shaft 20. The piston 3 has valve chambers 11, 12 with oppositely disposed valve seats 13, 14, 15, 16 respectively, and with ports 34, 36 communicating with opposite sides of the piston. A central suction chamber 17 is provided between the chambers 11, 12. The piston rod 5 has an aperture 31 in a cap 8 which permits air to pass to ports 24<a> in the valve shaft, and rod 5<a> has air apertures 31<a>. Conical valves 40 - - 43 . preferably of moulded rubber, which engage and are pressed towards the seats 13 - - 16 by spring washers, are mounted between collars on the shaft 20 which has a central partition 23. The left-hand end of shaft 20 is connected to suction pipe 62. An adjustable collar 21 and the collars 41<a>, 42<a> are so set as to hold the valves 41, 42 slightly off their seats in the end position of the piston, Fig. 3, so as to ensure the presence of a vacuum on both sides of the piston. After the brake has been operated, the slight opening thus provided prevents the delivery of air to the intake manifold of the engine in such quantity as to interfere with the running of the engine. A check valve 65 is arranged on the manifold connection to prevent the throttle 64 affecting the servomotor. On operating the lever 88, valve 42 is closed and valve 41 opened, and air is freely supplied to the right-hand side of the piston to effect its movement. When the operator stops, the piston continues its motion and brings the valves 41, 42 to their slightly-open position. When the brake lever is released and is moved back. wards by the spring 89, the piston is returned by the load on the brake without the admission of air to the left of the piston. When the operator removes his foot from the lever 88, the valveshaft moves faster than the piston, closes valves 41, 53 and opens valve 40 thereby admitting air to return the piston and brake to the off position. The valves again take up the position shown in Fig. 3. Lost motion between the collar 25 on the valve shaft 20 and the cap 8 and collar 26 on rod 5 enables the operator to add his physical force to that of the servomotor, or to operate the brake directly in case of failure of power. In a modification, a valve-like element similar to valve 40 is always closed so that air is never admitted to the left-hand side of the piston. Tn this construction the collar 21 is dispensed with, and the collar and the end of the shaft 20 engage the cap 8 when both inner valves are slightly open. Specification 226,514 is referred to.
