Abstract: 304,416. Graseby, R. C. Nov. 14. 1927. Electricity &c., supplying by meter; mechanism for prepaying rent of meter.-Prepayment meter mechanism with means whereby a, standing charge, such as rent, can be collected comprises controlling means, such as a switch, for the supply, prepayment or setting mechanism to operate the switch including an epicyclic gearing 2, Fig. 1, one sun wheel of which is connected to coin operated mechanism while the other sun wheel is connected through a second epicyclic gearing 27 to the meter driven mechanism 28 and to spring-driven motor mechanism, both of which act to return the setting mechanism to zero, the spring-driven motor mchanism being connected to the coin-operated mechanism so as to be wound when the prepayment mechanism is set after the insertion of a coin. A star wheel 1 actuated by a coin in a rotary drum sets forward a gapped, flanged disc 3 controlling a switch which is closed as described in Specification 1363/14. A spring 6 surrounding the spindle 7 of the disc 3 constitutes the driving means for returning the disc, its action being controlled by a flier 9 - - 12 as described in Specification 294,739, the barrel 11 being driven from a spring 20 through gearing 13 - - 17 controlled by an escapement 18, 19. The gear 15 comprises one member of the epicyclic gearing 27 the other member of which is directly connected to the meter driven wheel 28. The spring 20 is wound through gearing 22 - - 25 from the spindle 26 carrying the coin-operated star wheel 1. The spring 20 may be arranged to drive the disc 3 past zero position, after the supply is cut off, so that a coin must be inserted to return it to zero before any further supply can be obtained by the insertion of further coins. In this case the springs 6, 20 are arranged tn be in tension when the setting mechanism reaches zero. position.

Title: Improvements in or relating to control means for a motor vehicle tailgate
Inventor: HABGOOD GORDON ALFRED
IPC: B62D25/12
Filed: 1961-08-25
Abstract: 987,579. Window operating mechanism; latches. WILMOT-BREEDEN Ltd. Aug. 27, 1962 [Aug. 25, 1961], No. 30652/61. Headings E2A and E2M. A winding handle 36 for a window 2 in a motor vehicle tailgate can be folded up to a position in which the knob 38 faces inwardly relative to the tailgate and is aligned with release means for the tailgate latch so as to act as a pushbutton for latch release, interlock means being provided to prevent such release unless the handle is in the position corresponding to the lowered position of the window. The invention is particularly intended for use with a tailgate in which the window when raised engages guides fixed to the vehicle body. The tailgate carries at each side a latch member 15 adapted to engage a pin 16 fixed to the vehicle body and retained in either the latched or unlatched position by a pawl 22 to which it is connected by a spring 23. The latch members are released by a torsion bar 26 mounted in brackets 27 fixed to the outer panel 4 of the tailgate and having cranked end limbs 28 engaging the pawls 22 and a central cranked limb 42 for engagement by the knob 38. The handle 36 is pivoted at 37 to a handle mounting 30 and the handle shaft 32 is splined to a shaft 12 connected through a gear chain to the window lifting arms 9. When the window is fully lowered and the handle is folded about the pivot 37 the knob 38 enters the lower aperture 40 in a mounting plate 34 and displaces the limb 42 to the position 42a thereby releasing the latch members 15. The knob is held in the latch release position whilst the tailgate is lowered by a spring clip 44 so that the handle is not readily accessible for window operation; when the tailgate is subsequently closed the latch is tripped by engagement with the pins 16 and the resulting movement of the bar 26 ejects the handle from the clip. To ensure that the latch cannot be released when the window is raised a blocking plate 43 is riveted to the gear wheel 13 and is disposed behind the limb 42 to prevent movement of the latter. The plate 43 is clear of the limb only when the window is fully lowered.

Title: A regenerating arrangement for electrical pulses
IPC: H03K5/01
Filed: 1964-08-04
Abstract: 1,048,487 Transistor pulse circuits. TELEFONAKTIEBOLAGET L.M. ERICSSON. Aug. 4, 1964 [July 23, 1963], No. 30820/64. Heading H3J. In a circuit for regenerating bipolar signals and for re-inserting the direct current component, the signals are fed via a summation circuit S and then to a level stabilizer NS and limiting amplifier B, feedback being provided via a low-pass filter F. The level stabilizer has the secondary winding S3 of a transformer TR connected in series with the signal path and induces a pulse in the secondary winding under specified signal conditions. It is explained by means of waveforms (Fig. 5, not shown) that a positive-going step in the combined waveform from the summation circuit S turns on transistor T2, inducing a negative-going pulse in the secondary winding S3. A positive-going pulse is induced by transistor T1 on the occurrence of a negative-going step. The combined waveform U2 thus arranges that the output of the limiting amplifier B is reversed by pulse edges of only one polarity. Figs. 6, 7 (not shown) relate to a similar arrangement in which the pulse induced in the secondary winding S3 is of the same polarity as the step received from the summation circuit S.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/48
Filed: 1936-11-12
Abstract: 479,226. Cathode-ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Nov. 12, 1936, No. 30959. Convention date, Nov. 15, 1935. [Class 39 (i)] A cathode-ray tube of the cold cathode type is provided with a motor to change the active part of the emissive surface of the cathode. By this means the useful life of the tube may be increased, the emissive surface of the cathode being exposed progressively through the perforation in a screen, whereby the active surface is constantly changing. The cathode may be formed by a rotatable disc which is eccentrically mounted in relation to the slotted diaphragm and an apertured anode. Alternatively, the disc may be arranged behind a screening disc provided with a spiral slot, these two discs being rotatable and mounted coaxially with a second disc provided with a radial slot, so that, as rotation occurs, the emissive area of the cathode is displaced along a spiral over the cathode surface. In a modification, the cathode is a rotatablymounted cylinder 11 which is displaced relatively to an aperture 17 in a screen 16 by providing the cylinder 11 with a screw-threaded extension 18, which is engaged by a stationary screw 13, the movement being periodically reversed, when necessary. The rotation of the cathode may be produced by an inducing element 14, excited by polyphase windings to produce a rotating field which acts on the solid metal member to be driven ; alternatively, single-phase alternating current may be used to excite the inducing element, the driven member being magnetic and provided with peripheral teeth. Instead of a continuous rotary movement, an oscillation may take place, the inducing element then being an electromagnet and a small permanent magnet being fixed to the element to be driven. The cathode or a screen interposed between the cathode and anode may be driven by electrostatic means or may oscillate under the action of gravity, the oscillation being sustained by electrodynamic or electrostatic means. The supplementary screen 16 forms a secondary cathode and when this is of metal may form one electrode of an electron lens by the application of a suitable potential ; the primary emissive cathode may then constitute another electrode of the lens.
