Title: Improvements in or relating to location indicator for a train
Inventor: TYLER ELMER RAY
IPC: B61L3/00
Filed: 1969-05-08
Abstract: 1,208,876. Train location indicator. E. R. TYLER, C. P. BATTAILE and K. I. DYCHE. 8 May, 1969 [23 May, 1968], No. 23619/69. Heading B7N.  In a train location indicator, a tape or film driven at a speed which is a function of train movement and carrying a continuing pictorial representation of the track profile of the route, with associated crossings, speed information, gradient &c., is moved over a display area to present to a driver an indication of the route in advance with an adjustable length representation of the train superimposed thereon. The train representation is adjusted to the train length using the scale of the track profile. The usual speed and distance recorder 20 on the train is coupled to a speed controller unit 22 in which a switch-operated pulse generator is driven via an adjustable coupling from the distance measuring portion of the recorder. The generator supplies output pulses on line 88, each indicative of a set distance travelled by the train. The pulses energize a solenoid 98 which, in dependence on the direction of train can be pivoted about a support 106 to couple a drive pawl 128 mounted on its armature to one or other of the opposed runs 132 of an endless ladder drive chain 134. The chain is coupled to a film drive member 178 and to drive wheels 136, 140 one of which is clutched by a shifting member 162 into drive engagement with the spool which, depending on the direction of tape movement, forms the take-up spool. The shifting members 162 are operated by cam members 170 on the solenoid support as this is pivoted.  The tape which apart from the information carrying portions is transparent is driven across a display area having a translucent back panel 200 illuminated by lamps 236 and between the tape and the panel a second tape 212 adjustably mounted on spools 208, 210 is provided for indicating train length. This tape 212 has a clear portion and a coloured translucent portion and can be adjusted to provide over the display area a clear translucent portion indicative of train length and a coloured translucent portion showing the route ahead of the train.

Abstract: 1491663 Audio equalization system DOLBY LABORATORIES Inc 9 Dec 1974 [22 Dec 1973] 23685/76 Divided out of 1490970 Headings H4J and H4R In an audio equalization system, particularly for compensating for the change in effective frequency response of an audio system, due to the reverberative build-up of low frequencies in an auditorium, the signal is applied to a number of parallel channels, each of which includes a filter 50, to pass different frequency bands, a variable gain device 64, to provide control of the gain in the different channels, and a delay device 66, which delays the signals in the respective channels so that the channels having the greater gain are given a greater delay. The arrangement provides that the high frequencies are delayed so that they build up at the same rate as the low frequencies build up due to reverberation. To prevent discontinuities in the response characteristic due to phase differences at the edges of the pass bands of adjacent filters 50, the delays may be slowly reduced to zero after an "attack", or increase in level, in the sound signal.

Title: Method of and apparatus for displaying sets of measured values as curves
IPC: G09G1/16
Filed: 1971-04-19
Abstract: 1349792 Cathode-ray tube displays SIEMENS AG 19 April 1971 [10 March 1970] 23698/71 Addition to 1283706 Heading H4T [Also in Division G4] The apparatus of the parent Specification 1,283,706, in which a series of measured values fed from a store 4 are displayed as a curve on the screen of a display unit 1, the oldest measured value being erased when a new measured value arrives is modified in that a further store 4<SP>1</SP> holds desired values, these being simultaneously displayed on a screen for comparison with the measured values. As described measured values are displayed in the same line as associated desired values, the display of measured values starting as for example the centre of the screen, desired values for which no measured values exist being displayed in the upper half of the screen. In the embodiment of Fig. 2 (not shown) in which the store (4<SP>1</SP>) comprises a shift register (41) and input/output register (9) and the store 4 comprises shift registers (41<SP>1</SP>, 42) and input/ output registers (9<SP>1</SP>, 10) initially the stores (41, 41<SP>1</SP> and 42) are each filled with one hundred values. Then if one hundred new desired values are entered into register (41), the contents of register (41<SP>1</SP>) are simultaneously shifted into register (42) and the contents of register (42) lost. Alternatively the contents of this register may be shifted into register (411) the electron beam being blanked when the contents of register (41<SP>1</SP>) are shifted through the output register. In a further embodiment (Fig. 3, not shown) if for example 50 more desired values than measured values are available a shifting counter (19) is stepped to 50, the display of measured values commencing when a comparator (18) comparing the count in counter (19) with the count in a line counter 70 is triggered (that is at line 50). In order that the desired value curve does not start above the upper edge of the screen the shifting counter may be preset to for example 51 in which case the display of measured values would start at line 101. In the embodiment of Fig. 4 (not shown) for controlling the display of measured values, with a counter (19) preset to 51, a counter (27) is preset to 251 so that after the introduction of 100 desired values the first counter (19) is at 151 and a second counter (27) is at 37 (having been reset at 314). Consequently when the line counter (17) reaches a count of 151 a bi-stable (BK) is set and a first measured value is displayed. When the line counter reaches 37 the bi-stable is reset. The display of desired values is controlled by a single counter and two comparators switching a bi-stable at counts of 51 and 251. When dynamic shift registers constructed by the integrated MOS technique are used new measured values are written into the register when the line counter has reached the count corresponding to the address at which the newest measured value must be written.

Abstract: 709,411. Super-regenerative relay circuits IVES, T. H. Dec. 11, 1951 [Sept. 27, 1950], No. 23717/50. Classes 40 (5) and 40 (6) A super-regenerative receiver adapted to operate a relay comprises a control circuit which is pre-set such that in the absence of an incoming signal the radio frequency oscillations are at a low level. The circuit shown comprises an R.F. tuned circuit L1, L2, C1, a quench circuit L4, C4, L3 and an inductor L5 which is adjusted so that in the absence of received signals the amplitude of the R.F. oscillation is small and a large anode current flows. When signals are received a large reduction in anode current occurs thus permitting less sensitive anode relay R to be used. The inductor L5 may be wound with resistance wire and according to the Provisional Specification may be replaced by a resistance and supplemented by an H.F. choke in the lead between L1 and L3. Alternatively an absorption or rejection circuit could be inductively coupled to the R.F. circuit. In an alternative circuit, Fig. 2 (not shown), the quench tuned circuit is connected in series with the H.F. tuned circuit between grid and anode and the feedback inductor L3 is connected in series with L5 between the anode and a tap on the R.F. tuned inductor L1, L2.
