Title: Improved apparatus for reading timing indicia from moving record media
IPC: H04L17/12
Filed: 1962-01-24
Abstract: 922,329. Sensing record tapes. NATIONAL CASH REGISTER CO. Jan. 24, 1962 [May 15, 1961], No. 2632/62. Class 106 (1). Timing pulses are derived from the sprocket holes of a moving record tape by using two sensing devices producing relatively displaced overlapping sensing signals and means for generating a timing pulse when both signals are present. A single sprocket hole in the tape 1, Fig. 1, is sensed by photo diodes 2, 3 connected to amplifiers 4 and 5 having triggers to produce square waves A and B, Fig. 2. A data signal will be as illustrated at D. The timing pulses are to be controlled by control signals which are applied on leads 6, 7, 8, through OR gate 9 to give a signal C. Signals A, B and C are applied to AND gate 13 and the output inverted to generate signal 0<SP>f</SP>. Signals A and B combined in And gate 12 give signal l<SP>f</SP>. A flip-flop 10 is set or reset by these signals to give a signal F and this triggers a monostable circuit 11 to obtain the timing pulse K. The tape 20, Fig. 4, passes over a block 22 containing the photo-cells 25, 26 for reading the rows of data holes and photocells 31, 32 for sensing adjacent sprocket holes. As shown in Fig. 3, the photo-cell 31, is slightly offset from the line of data-reading photocells and the photo-cell 32 is correspondingly offset in the other direction with respect to the next line of data holes. In the form of Fig. 5, two photo-cells sense the same sprocket hole 24. Plate 44 has two apertures 45 and 46 beneath which are two photo-diodes 49 enclosed in a transparent envelope. Each photo-diode consists of a layer of light-sensitive " p " material sandwiched between two layers of " n " material. Light passing through the two apertures 45, 46 may pass to two separate photo-diodes via the internal reflecting surfaces of a prism, via two mirrors placed at an angle or via curved light guides. In a further modification there may be a single opening communicating with diverging bores in the photo-diode housing each leading to a photodiode.

Abstract: 606,424. Aerials; radio direction-finding. STANDARD TELEPHONES & CABLES, Ltd. Feb. 6, 1945, No. 3048. Convention date, Nov. 27, 1943..[Class 40 (vii)] In a direction-finding aerial system cbmprising a single-turn untuned loop aerial and an associated sensing aerial arrangement comprising a sensing aerial and a counterpoise, the sensing aerial arrangement is coupled to its transmission feed line through a dummy loop directly connected to the conductors of the line and having an impedance substantially equal to the terminal impedance of the loop aerial. The invention is described with reference to an aerial structure similar to that described in Specification 592,350 comprising a pair of perpendicular loop aerials 10, 11, Fig. 1, with a sensing aerial 15 and counterpoise elements 16 mounted above them. The dummy loop as shown in Fig. 1 comprises two shielded conductor lines 29, 30 connected at their lower ends to the conductors 25, 26 of the transmission feed line 24, and at their other ends to a coil 31 loosely coupled to a coil 21 connected over leads 17, 18 to the sensing aerial and counterpoise. The conductors 29, 30 preferably have the same characteristic impedance as the conductors forming the loop aerials and are of length equal to half the perimeter of each loop. Balancing condensers 22, 23 and decoupling impedances 19, 20 (resistances or inductances) may be converted as shown. If the loop aerials have series resistances to give wide-band frequency characteristics as described in Specification 592,350, the dummy loop has similar resistances 32, 33. In a modified arrangement, Fig. 2, the dummy loop comprises hollow tubular members 45, 46 coupled to the sensing aerial arrangement by an elongated coil 41. The members 45, 46 may be replaced by a simple shielded loop, Fig. 3 (not shown). In other arrangements, Figs. 4, 5 (not shown), a resistance coupling is provided between the dummy loop and the sensing antenna arrangement, and series resistances such as 19, 20, Fig. 1, are shunted by tuning condensers.
