Abstract: 1,240,588. Radio communication system. JAPANESE NATIONAL RAILWAYS, MITSUBISHI DENKI K.K., and SUMITOMO ELECTRIC INDUSTRIES Ltd. 17 July, 1969 [30 July, 1968], No. 36078/69. Heading H4L. A system is described for communication between a central fixed station 1, Fig. 3, and a plurality of trains moving along a railway track. The information to be communicated may be divided into two categories:- (1) Information which is to be received by all the trains, e.g. common train control, telephone, television, radio; (2) Information which is to be received by those trains on a selected track section only, e.g. anti-collision data. A leaky transmission line 2, e.g. Fig. 2, is run along the track from the central station and is interrupted at the beginning of each track section by a frequency selection and conversion means 30 1 , 30 2  .... Information in category 1 is modulated on to a high-frequency carrier F 3 , which is passed unchanged by all the means 30 and is radiated by the leaky transmission line along all its length to all the trains. Information in category 2 for trains on the 1st, 2nd and 3rd track sections for example are modulated on low frequency carriers f 1 , f 2 , f 3  respectively. Means 30 selects carrier f 1  and converts it to a high-frequency carrier F 1  which radiates from the transmission line to the required train. The means 30 2  does not let the carrier F 1  pass to the next section. Likewise, means 30 2  converts carrier f 2  to carrier F 1  for radiation to the required train. The trains may communicate with the central station 1, Fig. 5, by coupling into the transmission line on a common high frequency F 2 . Means 30 1 , 30 2 , 30 3  convert this down to f<SP>1</SP> 1 , f<SP>1</SP> 2 , f<SP>1</SP> 3  respectively for passage to the central station and stop the passage of carrier F 2  from its initial section to the next. Ground stations 31, Fig. 6, may be connected to the means 30 1  &c. and may communicate with the central station 1 using common highfrequency carriers F<SP>1</SP> 3 , F<SP>1</SP> 4  (category 1, outward and inward) and F<SP>1</SP> 1 , F<SP>1</SP> 2  (category 2, outward and inward) and individual section low frequencies f<SP>11</SP> 1 , f<SP>11</SP> 2  ... f<SP>11</SP> n  (outward) and f<SP>111</SP> 1 , f<SP>111</SP> 2  ... f<SP>111</SP> n  (inward), in the same manner as described.

Abstract: 1,082,952. Slide rules. DOWTY GROUP SERVICES Ltd. Sept. 14, 1964 [Sept. 16, 1963], No. 36394/63. Heading G4B. A slide rule is used for determining the number of items to be bought at one time in order to minimize total cost. The various scales may represent the following variables: Q, the quantity to be ordered; M, the number used in a given period; Cs, the cost of purchasing a batch of items; C, the cost of each item; I, the percentage of the cost of an item for storage and interest; It is stated that for a minimal total cost, and the configuration shown is designed to find the value of Q. The stock of the slide rule has logarithmic scales representing M and K, increasing in opposite directions, with the scale of K twice that of the scale M. The cursor carries a logarithmic scale representing C, and an oblique logarithmic scale on the slide represents Q. In use, the slide is set so that a mark A is against the required value on the K scale and the hair-line on the cursor is set against the appropriate point on the M scale. The value of Q is then read from the intersection of the Q scale with the C scale on the cursor. In another embodiment a second slide is carried by the stock, this having an I scale and co-operating with a Cs scale on the stock. By this means the value of K is computed by the slide rule before it is used to find the value of Q. In a further embodiment two slides are used bearing scales M and C and co-operating with scales K and Q. In this example, the cursor has no markings apart from a hair line. The reverse of the slide rule may be provided with similar scales, one of the factors having a different range. The scales may also be applied to a cylindrical or disc-type slide rule.

The system may include counters recording the number of cars entering and leaving the car park whereby the computer is arranged to take account of cars remaining in the car park outside normal operating hours. A car detection device is provided in the entrance and exit of the car park and consists of three normally-open switches P1-P3 operated in turn by the front and back wheels of a car to place a signal on line S1. The switches may be replaced by photo-electric detectors. The timing device consists of three sections D1-D3. Each section comprises a collector ring of alternate conductive and insulating strips L and F driven at a constant speed by a motor. The ring contacts a stationary brush b1 energized by the signal on line S1. Each conductive strip is connected to a corresponding ring to supplying lines f 0 -f 9 . The sections are geared together in the ratio 10 : 1 whereby the signal on line S1 generates a three-digit time signal on the lines f 0 -f 9 . The signals on lines f 0 -f 9  operate corresponding relays K to electromagnetically operate the appropriate keys in the units, tens, and hundreds banks E1-E3 of a calculating machine. Operation of the car detection device in the entrance sets the calculating machine for subtraction. The signal on line 51 also automatically opens and closes a barrier, actuates a ticket printing mechanism, steps a car counter, and operates a visible or audible signal. In a modification, Fig. 4 (not shown), the switch P1 in the car detection device or a manually operable switch (Q) is operated when a car enters the car park to disconnect the timing device from the calculating machine and the signals from the collector rings passed through banks of two-way switches (M) to energize corresponding relays controlling a ticket printing and issuing machine.
