Abstract: 530,519. Television ; cathode-ray tubes; delay devices. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and PLATSTOWE, D. L. June 9. 1939, No. 17014. [Classes 39 (i), 40 (iii) and 40 (v)] A controllable delay device, particularly for television synchronizing signals in systems in which the camera is some distance from the transmitter, comprises an electron beam valve having two anodes P3, P4, the controlling signal, which may be a saw-tooth potential applied via C1, R1 to the deflecting plate P1, deflecting the ray from P3 to P4 after an interval determined by the initial position of the ray i.e. by the biasing potential applied to a second deflecting plate P2 by a potentiometer R2. Saw-tooth potentials applied to P1 produce rectangular pulses on the anode P4 with a delay determined by the adjustment of R2 and a duration inversely dependent on the amplitude of the saw-tooth potentials. The rectangular pulses may control a saw-tooth generator. The beam is suppressed during the fly-back period by negative pulses Q2 applied to the Wehnelt cylinder W. The anode P3 has a central aperture or slot through which the ray, when deflected, passes to the anode P4.

U 1m .. .U n1 ... U nm  a holding store HS1 ... HS n  is provided for each row (or each column) and, when a crosspoint connection between a row and a column is required, the binary coded address of the particular crosspoint is recorded in the store assigned to the particular row (or column), the output from each store being connected to a respective decoder DK1 ...DK n , the outputs of which are connected individually to control inputs of the switching elements at the crosspoints of the row (or column) to which the store is assigned. If a call is received on an input line, Z 1  say, a control circuit ST searches for a free output line, S, say, and writes its address in store HS1. Decoder DK1 then provides an output which enables F.E.T. AND gate U1 so that data from input Z1 will pass via AND gate U11 and OR gate O1 to output S1. The addresses of operative switches may be stored in marker stores MS1 ... MSm assigned to the columns if the holding stores are assigned to the rows, or vice versa. If subsequently a particular connection is disestablished, the relevant switching element may then be left switched through. When required for another connection, the address stored in the marker store provides an instruction to erase the previously stored address in the holding store. Alternatively the holding stores may be checked by a comparator which erases the contents of the holding store which are identical with the address of the new connection. The holding stores are connected to the rows or columns, whichever are lower in number.

Abstract: 1534076 Rotating fuel nozzles in carburetters AUTOELEKTRONIC AG 28 April 1976 [9 May 1975 28 July 1975] 17340/76 Heading F1B A carburetter for an I.C. engine comprises a rotor 2 to a fuel compartment 6 of which fuel is supplied through a conduit 1, the rotor 2 being rotated in use by an impeller wheel (16), Fig. 2 (not shown) by air-flow through the carburetter to cause ejection of fuel from the rotor 2 to a mixing compartment through lateral nozzles 10, the rotor having a fuel distribution compartment 7 to which opens an annular air inlet opening 8. The compartment 7 may communicate with the compartment 6 either directly as in Fig. 8 or Figs. 6, 9 (not shown) or via an annular gap 5 or 5a as in Fig. 1 or Figs. 2, 3, 4 (not shown). Fuel which would be of a depth shown by line N when the rotor is stationary is caused by rotation to assume the position shown shaded in Fig. 1 to be forced through the nozzles 10. In the embodiment of Figs. 4 and 4a (not shown) fuel channels (17) which may have nozzles (17a), (17d) at the upstream and downstream ends lead from a frustoconical recess (6a) of fuel compartment 6 so as to supply fuel to the carburetter mixing compartment at low air-flow rates and therefore low fuel chamber rotation rates. To provide enriched mixture during idling the impeller wheel may be acted on by a weak eddy current brake, the braking effect being greater at high rotational speeds than at low. The air inlet opening may be provided by an opening 11 of a ball-bearing 3 if insert member 9 is omitted. Additional air may be mixed with the fuel before atomization via a passage (20) Fig. 5 (not shown). In Fig. 8 fuel passes from compartment 6 via channel 17 to nozzle 10 downstream of which is an atomizer device in the form of a spray edge which may be a ring 35 formed integrally with the impeller wheel 16. An end section 17g of the channel 17 is dimensioned so that the fuel flow-rate through the nozzle 10 is approximately proportional to the square root of the fuel excess pressure in the channel. Figs. 9 and 10 (not shown) relate to embodiments having more than one fuel channel 17, (17') leading to nozzles 10, (10') which may be axially spaced from each other and may be angularly spaced by 180 degrees or by a smaller angle.

Abstract: 195,034. Alma, M., and Alma, C. E. March 18, 1922, [Convention date]. Combined buffer and draw-gear.-In combined buffing and draw-gear for railway and like vehicles of the kind comprising two draw-rod halves or parts displaceably connected at the centre of the vehicle and subjected to spring action, the springs are disposed between sleeves displaceable in fixed bearings and connected with the draw-rod. The buffing and draw-rods b are each carried in fixed bearings e, f, and r, and are connected at the centre by a muff coupling d to which they are slidably connected by cotters o working in longitudinal slots p, q in the coupling. Sleeves g, h slide in bearings e, f and are fixed to the rod b by cotters i, j, respectively. A buffing and draw spring m is mounted between the bearings e, f and is acted upon by the sleeves through plates k, l. In buffing, the rods b com press the springs m against the bearings f until the cotter i contacts with the bearing e or the coupling head a with the headstock c, or both, the end of the rod b sliding in the muff coupling d. When buffing from both ends the ends of the rods b in the muff coupling contact before the springs m are fully compressed. In draught the spring m is forced against the bearing i and compressed until the cotter j contacts with the bearing f, the cotter o sliding in the slot in the muff coupling; the amount the draw-rods can move apart from each other upon the occurrence of a draw or pull, is determined by the lengths of the slots p, q in the muff coupling d. This amount is preferably smaller than the sum total of the amounts of play of both springs m.
