Patent GB-439559-A (GB)
Title: Improvements in methods and apparatus for recording sound
IPC: G11B11/18
Filed: 1934-03-06
Abstract: 439,559. Recording sound or like vibrations. SANTEAU, P., 19, Rue Dupont de l'Eure, Paris. March 6, 1934, No. 7182. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 7, 1934]. [Class 40 (ii)] Relates to the production on a band or film of sound or like records of the variablewidth type, mainly intended for optical reproduction, the records comprising a number of sound tracks recorded simultaneously and occupying the same space on the film as a sound track of normal width. Each elementary track may be bounded on one side by a sinuous line and on the other by a straight line, or on both sides by sinuous lines. Various methods of and devices for producing the record are as follows : (1) the sound tracks may be traced in ink by means of a set of pens with multiple nibs. Fig. 4 shows one such pen separately. The nibs 2, of various lengths, are arranged as shown in a holder 3 through which ink is supplied, each nib having a hollow blade and a grooved tip. The nibs are pressed elastically against the record band 1 which is vibrated towards and from the pen in accordance with the sound to be recorded. A number of such multiple-nib pens are arranged side by side, for example three pens may be so arranged as to be capable of producing a sound track having a maximum width of 6 m.m. (2) The record may be made mechanically on a film coated with an opaque layer by using a multiple-toothed vibratory engraving tool 3 as shown in Fig. 9, to form the sound track by removal of the coating. Reproduction from such a record may be effected photo-electrically, or by means of a blunt pick-up needle. The grooves or the film may be inked. Instead of using a coated film, the sound track may be engraved on a film by means of a tool having teeth which are perfectly rectilinear and polished. Reproduction is effected from such a record by light which is modulated by reflection from the walls of the groove. (3) The sound may be recorded photographically, using the device shown diagrammatically in Fig. 12. This apparatus comprises two identical oscillographs to the coils 8, 9 of which, connected in series, the sound-modulated currents are supplied. Concave mirrors 6, 7, thus vibrated, reflect light beams each passing from a separate source 2 or 3 through grids 4, 5 respectively, the reflected beams passing through a third grid 10 on to a film 1. With the arrangement shown, six elementary sound tracks, each bounded by a sinuous line, are formed side by side on the film. The light source 3, grid 5, and oscillograph 7, 9 may be replaced by a reflecting system. It is stated that " the invention is applicable without modification to non-juxtaposed sound tracks of which only one part is used." The advantages of the described methods of recording are fully explained.

Title: Drawer mechanisms for automatic banking units
IPC: G07D11/00
Filed: 1975-02-21
Abstract: 1488927 Banking equipment DIEBOLD Inc 21 Feb 1975 [25 Feb 1974] 7273/75 Heading G4X An automatic banking unit has a housing 1 and a rotary cash drawer 6, the drawer is movable between a "home" position as shown in Fig. 2, an "open" position as shown in Fig. 13 and a "dump" position, Fig. 14 (not shown). In the "home" position the drawer can receive currency from a currency supply and delivery mechanism 7. In the "open" position the currency can be removed from the drawer by an operator and receipts or the like placed in the drawer. In the "dump" position the drawer is inverted and anything in the drawer is deposited in tray 39. The sequence of movement of the drawer is from the "home" position to an "open" position and then from the "open" position to the "dump" position after a predetermined time interval or after a signal has been produced. Finally the drawer moves from the "dump" position to the "home" position. If the count of the delivery of the currency to the drawer is incorrect an operator cancels his transaction before the drawer moves to the open position, the drawer is moved direct from the "home" to the "dump" position. The drawer consists of a rotor 23 with a cylindrical wall 24 supported in frame members 9, 10 and end frame members 11 and 12. The rotor has a slot 36 and a liner 37 extending axially thereof to form a pocket 38. Partition walls 29, 30 form cavities 31, 32 at each end of the rotor, which cavities surround stub-axles 25, 26. Positioned in the cavities are counterweights (43) (44) Fig. 5 (not shown). Drive for the rotor is by motors 92, 95 dependent on the direction of rotation of the rotor. The motors are mounted on a plate 89 which is pivotally mouned at 90 to frame member 11 and is movable by solenoid 97. A gear wheel 94 is mounted on stub-axle 25. For clockwise rotation of the rotor, as viewed in Fig. 2, gear wheel 93 is engaged with gear wheel 94. For anti-clockwise rotation friction drive wheel 96 engages the outer surface of the rotor. The friction drive is used as a safeguard against an operator getting a hand stuck in the drawer, A ratchet wheel 102 and ratchet pawl 103 are operative only during friction drive of the rotor and prevent the rotor being forcibly moved against the action of the fraction drive. A stop pin 71 engages in opening 72 when the rotor is in the home position. When the rotor is in the open position electric eye bulbs 60a, 6Àb can project a light beam to photocell sensors 63, 64 via prisms 56 and 54, as shown in Fig. 6. Before removal of currency this beam is obscured. Removal of the currency allows the light beam to pass and a signal is thus produced to signal the start of the next phase of the operation. A rib 109 in the pocket tilts paper currency off the vertical. A switch plate 75 has light sensers thereon which are interrupted by fingers 82, 84 on a disc attached to stub-axle 26. The sensers denote the different positions of the rotor. The circuitry for operation of the unit is illustrated in Fig. 17 (not shown).

A D.C. amplifier comprises a pair of valves 40, 50 cathode-coupled by a resistor 60 and direct coupled to a pair of cathode-followers 70, 80. The input is applied via terminals 104, 108 to the grid of valve 40 and to line 103, which may be earthed by means of removable link 107. The valve 50 obtains grid bias from a fixed potentiometer 62, 63 in the common cathode circuit while that of valve 40 is obtained from potentiometer 61 which is adjustable for the purpose of balancing the amplifier. The current in the network 61, 62, 63 is in part determined by resistor 32 connecting it to the H.T.+ supply. Each of the cathode-followers 70, 80 is provided with a separate cathode resistor 71, 81 respectively, these resistors being of relatively low value so as to reduce the output impedance. The cathodes of the valves 70, 80 are brought to the necessary positive potential by means of a gas discharge tube 92 common to the two cathode circuits, and connected to the H.T.+ supply via a further discharge tube 34 which also serves, in conjunction with resistor 26, to stabilize the H.T. supply to the valves 40, 50.
