Patent GB-1011831-A (GB)
Title: Dictation apparatus
IPC: G11B25/06
Filed: 1964-05-08
Abstract: 1,011,831. Belt recorders. DICTAPHONE CORPORATION. May 8, 1964 [May 15, 1963], No. 19385/64. Heading G5R. Dictation apparatus of the belt record type is provided with means operable from outside the apparatus for controlling back and forward spacing. Spacing in either direction is initiated by a solenoid 28, Fig. 2, controlled by a footswitch (not shown), and the armature 30 of the solenoid is adapted to close two switches 32 and 34, of which one mutes the sound circuit and the other energizes a clutch (not shown) so that a cam 26 is driven from the main driving means. Movement of armature 30 causes the toe 52 of a pawl 46 to engage a notch 54 in a cam follower 36 so that a bell-crank 50, on which the pawl 46 is mounted, is rotated. The crank 50 is rigidly attached to a guide rod 14, and rotation of the guide rod causes a carriage (not shown) carrying the transducing head to be locked to the guide rod, as described in Specification 1,010,156, so that longitudinal movement of the rod will cause forward or back spacing. Rotation of crank 50 exerts pressure on two wire springs, of which one 76 is shown, which tend to lift their associated links, of which one 80 is shown. One of the two links is restrained by a selector tongue 94 of a solenoid 98 according to the condition of the solenoid, which thereby selects forward or backward spacing. When the backspacing link 80 is allowed to lift, the degree of lift is limited by engagement of a stop 134 with a stop plate 136 which can be set in one of three positions by means of a control button 150 to determine whether the back spacing shall correspond to two, four, or six grooves on the record. In accordance with the setting of stop plate 136, a tooth 124 on link 80 engages one of three steps on an actuator arm (not shown) carried by a cam follower (not shown) riding on the cam 26. Movement of link 80 by the actuator arm causes rotation of a cam 68 which causes longitudinal movement of guide rod 14 to achieve the desired back spacing. When the latter is completed the cam follower 36 allows the bell-crank 50 to return to its initial position, thereby releasing the carriage from the guide rod 14. The forward spacing mechanism is similar except that there is only one increment of forward spacing, for example six grooves.

Title: Dispensing nozzles
IPC: F16K21/20
Filed: 1975-05-08
Abstract: 1504039 Petrol dispensing nozzles SUN OIL CO OF PENNSYLVANIA 8 May 1975 [10 May 1974] 19393/75 Heading B8N A petrol dispensing nozzle with automatic shut-off when an inlet 25 is closed by rising petrol in the filling pipe 29 controlled by a diaphragm 6 has the chamber 23 on the reference side of the diaphragm subjected to the pressure in the petrol tank being filled. In one embodiment a pipe 38 leads from the chamber 23 to a vapour recovery pipe 37. In a second, more practical, embodiment, Fig. 4, the tank pressure is ducted 24 to the chamber 22 and through a check valve 45 in the diaphragm to the chamber 23. The nozzle is sealed to the filling pipe 29 by a magnetic disc 34. The automatic nozzle thus operates with the petrol tank pressure as the reference pressure rather than atmospheric pressure as in known dispensing nozzles.

Filed: 1951-09-06
Abstract: 741,649. Television pick-up tubes. PYE, Ltd. Sept. 8, 1952 [Sept. 6, 1951], No. 19476/54. Divided out of 741,592, [Group XL (b)]. Class 39 (1). Relates to a television pick-up tube of the image iconoscope type described in Specification 656,069 comprising a photo-cathode 6 and a target electrode 8 which is scanned by means of a beam of electrons released by a flying spot scanner 1 scanning the photo-cathode. According to the invention an electron multiplier 22 is provided facing the photo-cathode so as to be responsive to the electron emission therefrom. A second electron multiplier 21 faces the target electrode. The tube may be operated either as a conventional storage tube or as a photocell. For operation as a storage tube a scene 16 is projected on to the photo-cathode and the flying spot scanner is arranged to scan the same area as that occupied by the scene. The stored charges produced on the target 8 are discharged in turn by the scanning beam of electrons released by the flying spot scanner and the discharge current, which constitutes the image signal, is fed to the amplifier 14 through the electron multiplier 21. For operation as a photo-cell, a transparency, such as kinema film 17, is inserted in the light beam from the flying spot scanner 1 and the output signal is derived through amplifier 19 from the photo-emission received from the photo-cathode by electron multiplier 22. During such operation, coil 10 employed normally for focusing the electron image on the target 8 is preferably not energized. According to a further feature of the invention, the target 8 and its associated signal plate 9 are made semi-transparent, whereby light from an image may be projected on to the rear of the photo-cathode alternatively or simultaneously with the light from image 16. The electron multipliers may be constructed as described' in Specification 721,943. Apparatus incorporating the pick-up tube and arranged to be operated either as a flying- spot scanner or a storage-type pick-up device forms one subject of Specification 741,592, [Group XL (b)].
