Title: Improvements in or relating to television and like systems
IPC: H04N5/067
Filed: 1934-06-01
Abstract: 443,699. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Campbell, R. L. ; 56, Ridgeway Avenue, Oaklyn, New Jersey, U.S.A.) June 1, 1934, No. 16422. Convention date, June 1, 1933. [Class 40 (iii)] Interference between frame-synchronizing signals and line-synchronizing signals, transmitted over the same channel as described in Specification 428,168, is prevented by suppressing the former during the occurrence of the latter. The invention is particularly applicable to the systems of interlaced scanning described in Specification 420,391, wherein the timing of the line-synchronizing signals 84 is related to that of the framing signals 86 as shown in Fig. 2 for odd-numbered frames and as shown in Fig. 3 for even-numbered frames. In the arrangement shown in Fig. 1, which is not claimed, both line and framesynchronizing impulses are generated by a generator 46, which may be of the kind described in Specification 395,499. After being amplified at 52 the line and frame impulses separate and the line impulses control the saw-tooth generator 20 feeding the deflection coils 18. Impulses of the form 70, Fig. 1, are derived from the coils through the path 72 and, after amplification by valves 60, 58, are fed as positive impulses to the amplifier B through a coupling resistance 66 which also receives frame-synchronizing impulses derived from deflecting-coils 22 through the connection 78 and valves 64, 62. Alternatively the impulses may be derived directly from the saw-tooth generators 20, 24 through connections 72a, 78a, instead of from the coils. Impulses from the amplifier B are sent on through the wireless transmitter 44 and for this purpose are fed to the amplifier 40 through the conductor 98 at such a stage and at such strength as to produce flat-topped synchronizing signals free from extraneous signals. A different stage of the amplifier 40 is controlled through the connection 94 so that undesirable signals are blocked out while deflecting fields for the scanning ray 16 are passing through their return period. Impulses are also applied through connection 90 to cut off the scanning ray 16 during these return periods. The width and amplitude of the impulses can be regulated by means of the potentiometer 102, resistance 104, condenser 106, or grid bias of valves 60, 64. In the arrangement shown in Fig. 1, which is not claimed, the line impulses are suppressed during transmission of the frame impulses, and for this purpose impulses derived from the frame-frequency amplifier 64 are passed through amplifiers 110, 114 to a suppressor grid 120 so as to disable the line-frequency valve 58 at the required times. According to the invention those parts of the frame impulses 86 which coincide with the line impulses 84 are suppressed as shown for odd-numbered and even-numbered frames respectively in Figs. 5 and 6, the valve circuits being arranged for this purpose in the manner indicated in Fig. 4 (not shown).

Title: Water-dispensing apparatus particularly for concrete mixers
Inventor: HAYWARD JOHN
IPC: B28C7/12
Filed: 1954-06-04
Abstract: 776,978. Water-waste-preventing cisterns. WINGET, Ltd. May 13, 1955 [June 4, 1954], No. 16625/54. Class 26. [Also in Groups XVIII and XXIX] A water-dispensing apparatus comprises a main chamber 4, Fig. 1, and a float chamber 5 connected by a conduit 6, a float-controlled inlet valve 8, an outlet valve 11, means 19 controlling the level of the liquid which is fed into the main chamber 4, and means arranged externally of the apparatus for varying the operative position of the means 19. The latter consists of a pipe which communicates with a vertical extension pipe open to atmosphere and is adapted to be angularly adjusted with the aid of a scale and locked by a wing nut (not shown). Water admitted by the valve 8 from the supply flows into the chamber 4 by way of the conduit 6 until the lower end of the pipe 19 is covered when the air trapped in the chamber 4 prevents any further rise in the level of the water within the chamber. Water then continues to rise in the pipe 19 and the conduit 6 until it lifts a float 7 to close the valve 8. To allow the water to discharge, the valve 11 is lifted by a lever 13 and a rod 12, the latter carrying an abutment 25 to keep the valve 8 closed while the valve 11 is open. Fig. 5 shows a modification wherein two chambers 27, 28 are connected by transfer pipes 29, 30 and 32. When a valve 60A is lifted to allow the water to discharge, a rod 61 forming part of the valve-operating mechanism lifts a lever 53 carrying a cam 55 so that the latter may be rotated clock-wise by the descent of a float 60 to which it is connected. Closure of the valve 60A causes the cam 55 to engage a trip lever 50 and thus lift a pilot valve 44 which causes a diaphragm valve 38 to open and admit water from an inlet 33 to the chambers 27, 28 until the float 60 has rotated the cam 55 far enough to release the trip lever 50 and hence allow the valve 44 to close. The valve 44 controls the flow through a bleed orifice connecting the inlet 33 to the chamber 28, the pressure drop through the orifice causing the valve 38 to open.

Title: Improvements in and relating to a diaphragm for a photographic camera
IPC: G03B9/08
Filed: 1961-05-08
Abstract: 906,362. Photo-electric exposure control. AGFA A.G. May 8, 1961 [May 11, 1960], No. 16689/61. Class 40 (3). [Also in Group XX] A diaphragm for a photographic camera includes two relatively movable leaves having congruent cut-out areas, the arrangement being such that the maximum diaphragm aperture is set when the said areas are in maximum register, movement of the leaves in the same relative direction increasing the aperture to the maximum and reducing it again and movement in the opposite direction achieving the same effective result, thus providing for two different aperture ranges, one on each side of the maximum aperture, and the diaphragm being adapted for operation by two independent means, each arranged for reciprocal relative movement of the leaves in a different one of the said two ranges, one of said means being an automatic exposure regulating means and the other of said means being a manual setting means, a semi-automatic exposure regulating means or an automatic exposure regulating means, the latter corresponding to a different exposure programme from the other said automatic exposure regulating means. As shown, diaphragm leaves 6, 7 are both pivoted at 8 and have exposure aperture defining areas 9, 10 respectively cut-out therefrom. For automatic setting of the diaphragm, manual setting means 16 is positioned at the end of a slot 2a-as in Fig. 1-and the leaves are set by means of a member 15 which bears two cam portions 15b, 15a engaged respectively under spring loading (not shown) by pins 11, 13 on the respective leaves and which is coupled-in known manner-to a scanner 4 for an exposure meter pointer 3. For manual setting of the diaphragm, member 16 is rotated in the clockwise direction from the position of Fig. 1, whereupon cam 16b, 16a thereon respectively engage pins 12, 13 on the two leaves and pivot them through their maximum aperture defining positions to the said second range. Areas 9, 10 may be in the shape of quadrilaterals (as shown), polygons, elipses, or approximate elipses. In modifications the positions of the co-operating pins and cams may be interchanged, each blade 9 and 10 may be provided with only one pin and the cams may be in the form of slots. The blades 9 and 10 may be provided with separate pivot points. In further modification, the member 16 may be coupled to a follow-up pointer or may be coupled to a second automatic exposure regulating means.

Title: Adaptor for electronic flash lamps
IPC: G03B15/03
Filed: 1973-04-06
Abstract: 1424067 Flash adapter device FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 6 April 1973 [24 May 1972 8 June 1972] 16695/73 Heading G2X An adapter for connecting electronic flashlamps to a camera having provision for the firing of percussion-ignitable flash-lamps has a firing switch in the electronic flash circuit which is closed when the percussion device is actuated. As shown, the camera housing 1 has a flash-lamp socket 2 and an adapter housing 14, the housing having rotatably mounted therein a foot 3. The foot 3 has four apertures 6, 90 degrees apart, and through these apertures pass crosspieces of a locking element 4 which is urged downwards by a spring 9. Element 4 has a handle 7 by means of which it can be withdrawn, against the spring, as far as a stop 11 in housing 14. Foot 3 is provided with four apertures 12 through which an element 5, coupled with the percussion ignition device 5a of the camera, can pass. Via a switch 21 the element 5 actuates a contact 8 which is part of the circuit of the ignition device 31 of the electronic flash-lamp 30. This lamp has a foot 32 which fits into an accessory shoe 10 formed in the adapter housing 14. The shoe 10 carries contacts 23, 24 which connect with contacts 33, 34 in the foot of the flash-lamp. Thus the closing of contact 8 by element 5 causes the flash-lamp 30 to fire. Since with percussion-ignited flash-lamps there is a longer delay between ignition and light emission, a delay circuit is provided so that the electronic flash does not occur before the shutter is fully open. Figs. (not shown) 2a, 2b, and 2c are examples of various delay circuits which can be used.

Abstract: 334,257. Automatic Telephone Manufacturing Co., Ltd., Gillings, C., and Paulett, W. H. May 31, 1929. Automatic exchange systems. - In a hunting type switch in which hunting is controlled by the interaction of a magnet and an interrupter relay, the interrupter relay is held operated in series with the test relay when a free circuit has been reached until the test relay has opened another point in the circuit of the stepping magnet. The invention is described as applied to a bi-directional call finder with two sets of wipers, only one set being used at a time, which is directly connected to a selector switch. Specification 334,218 is referred to. When a call is made LR operates replacing the normal earth on the wiper P by battery through CO and operating the start relay A. The calling level is marked in the bank wiped by VW. D operates to connect up the upper wiper set and relays A and B of the selector pull up to guard the line. Magnet V energizes to step the switch one vertical step and relay G pulls up over contacts V. Relay G and magnet V inter-act until the level required is reached when G remains operated in series with T to earth over the test wiper. Relay T locks.up, breaking the circuit of V, releasing G and changing over to the rotary magnet R. Relay G and magnet R then inter-act until the calling line is found when G holds up in series with H. Relay H locks to the test conductor, breads the driving magnet circuit, and switches the speaking circuit through. The first digit train is repeated by A to the vertical magnet of the selector and the switch steps to the required level. When C falls back at the end of the train magnet R operates and relay G and magnet R interact stepping the wipers until a free circuit is reached when G remains operated, in series with switching relay H. to battery over the test wire. If the finder fails to find the calling line, the finder cam springs S operate on the eleventh rotary step locking up G and H. Relay T releases and G and H fall away releasing the switch. If the selector fails to find a free outlet, the selector cam springs S operate and busy tone is returned to the calling line.
