Title: Improvements in or relating to variable-speed friction gearing
IPC: F16H15/08
Filed: 1921-08-22
Abstract: 182,027. Caubergh, C. P. L. van. Aug. 22, 1921. Variable-speed friction gearing, suitable for motor vehicles, of the type in which a jointed driven shaft is tiltable to traverse an annular flange carried thereby across the driving-disc, comprises a driving-disc a, Fig. 1, having an annular 'depression generated by an arc struck from the pivotal point z, which is eccentric to the driven shaft d. The face of the driven ring e has a corresponding curvature, and has also a bevelled edge f operative in reverse. The shaft d has a universal connection g with a shaft h, for instance the propeller-shaft of a motor-vehicle, and runs in a slidable casing n which transmits to the driven disc c the pull of a spring i, Fig. 6, so acting through the variable leverage of camlevers l, fulcrumed on trunnions m, that the engaging-force on studs o on the casing increases with speed-ratio reduction. The sleeve n is tilted by a hand-lever t and lifting-levers r engaging a slot w. When the ring e reaches the neutral zone of the disc a, as shown in Fig. 6, notches in extensions x of the levers r engage the ends of a bar k connecting the levers l and put the spring i out of action, so that a spring p disengages the gear. Upon further movement, the levers l are again freed, and the bevelled edge f engages the disc a beyond its centre. The gear may be disengaged at any time by a pedal &c. acting on the cam-levers l.

Title: Improvements in or relating to the control of automatic selector switches for telephone or other remotely controlled systems
IPC: H04Q3/42
Filed: 1930-07-24
Abstract: 359,542. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, London.-(Hatton, W. ; 46, Avenue de Breteuil, Paris.) July 24, 1930, No. 22324. [Class 40 (iv).] A uniselector is set in response to a code transmitted from a register which has been set in accordance with the wanted subscriber's number. The code is received by a relay group, common to a plurality of switches, which marks the wanted line or group of lines in the banks of an associated selector switch. When a call originates the registor, Fig. 1 is seized in the manner described in Specification 318,945 [Class 40 (iv), Telephones &c.], and the first digit sets register SW1. When the first impulse train is completed I releases, J operates, and G pulls up. K operates before G energizes completing a circuit over wire a to energize HE (Fig. 2). FS operates stepping brushes 1 . . 5 in search of the calling link, whereupon BC pulls up over 3, breaking the stepping circuit and energizing J1, FC, and FC1. Relay J1 switches the incoming a and b wires to relays SA .. SD, the earth over SD, SB being extended over b to PP, Fig. 1. P1 energizes and Q pulls up connecting the a and b wires to brushes d and e of SW1 - Relays SA and SB are polarized, whilst SC and SD are marginal and a combination of these relays is operated depending on the positions of the brushes and e of SW1. Relay Q closes a circuit for S which in turn allows M to pull up. K falls away and PP, P1, and Q de-energize, relay Q disconnecting d and c of SW1 from the relays SA .. SD. This relay chain ensures that Q is energized for a time sufficient for the relay set to operate. The release of Q energizes R which completes a homing circuit for SW1 which in turn connects the line circuit to SW2. In the control circuit a combination of the relays SA . . SD have been energized and corresponding relays AA . . AD energize to mark bank E of the switch PJ. When relay Q released the energized code relays SA . . SD fall back, but the operated relays AA .. AD lock in series with EE Which pulls up, when the code relays release, disconnecting the a and b wires and connecting earth to the b wire. EE also completes a circuit for PJM to step PJ in search of the contact marked by earth on HC through contacts of the marking relays. When the marked line is reached battery over c of PJ, 5 of FS, I of FS, and e of PJ operates HC and SS, HC opens the circuit of PJM and SS energizes J2 switching the call through and releasing the control circuit. The second, third, and fourth digits operate succeeding selectors in a similar manner.

Abstract: 1,102,137. Fuel elements. HITACHI Ltd. 23 May, 1966 [24 May, 1965; 11 June, 1965], No. 22964/66. Heading G6C. A fuel element for a nuclear superheat reactor comprises fuel material and a process tube surrounding and spaced from the fuel material to provide a coolant passage, the process tube being made at least in part from a fertile material and/or a burnable poison whose fissile material content is lower than that of the fuel material, the process tube providing thermal insulation between water vapour coolant passing through the passage and a moderator. The fertile material may be depleted uranium oxide or natural uranium oxide or their mixtures, while the burnable poison may be boron carbide, europium or dysprosium. The addition of a very small amount of burnable poison to the process tube is sufficient to compensate for the fuel burn-up, whereas the addition of fertile material is never fully sufficient for this purpose. However, process tubes containing fertile material in producing fissile material are highly useful from the viewpoint of neutron economy.

Class 98(1) In a camera film-winding mechanism, a film take-up spool is adapted to be rotated, through gears, by a winding knob mounted with its axis parallel to - but displaced from - the axis of the take up spool, the winding knob being slidably mounted on a spindle so as to be movable into any of three positions; a first position in which the knob is sunk into a recess in the camera wall and linked with the spool, a second position in which the knob is still linked with the spool but sufficiently withdrawn for manual winding, and a third position in which the knob is fully withdrawn from the recess and unlinked from the spool, a dog which engaged the spool during linkage being withdrawn in the third position to permit removal thereof, and release of the knob from its first position being effected by pressure on, and slight rotation of, a knurled face of the knob. As shown, an axially displaceable pin 4 is secured at its upper end to a bearing part 3 and at the lower end carries an axially slidable spool engaging dog 5 which may be brought into and out of engagement with a spool 6 in a cassette 7. The dog 5 has a gear pinion 8 which engages a further pinion 11 having a bush 13 turnable about the pin 12. A film winding knob 14 has a cylindrical extension coaxial with the bush 13, and in the position shown is held within a recess 15 in the wall 7 of the camera by means of a coupling pin 16 engaging a short horizontal extension of a longitudinal bayonet lock 17. Rotation of the knob brings the pin 16 into the vertical part of slot 17, and the spring 20 urges the knob upwards to position for winding the spool; further manual lifting of the knob 14 lifts the dog 5 clear of the spool by co-operation of pinion 11 with the plates 9 and 10 which further cooperate with spring 22 to lock the mechanism in the uncoupled position. In a further embodiment, the driving mechanism is coupled with automatic driving means.
