Title: Improvements in or relating to braking control systems for vehicles
IPC: F16D65/14
Filed: 1957-03-07
Abstract: 811,812. Hydraulic brakes. FRANCAISE DU FERODO S.A. March 7, 1957 [March 8, 1956], No. 7675/57. Class 103 (1). In an hydraulic brake system the primary and secondary pressure lines 48 and 23 extend between the master cylinder 10 and the wheel cylinders 52, the primary lines being pressurized from four chambers between the end of the master cylinder and four separate pistons 36, the secondary lines extending from a connection 22 above a valve 24, 25, past which the pressure created in a chamber 16 produced by an initial movement of piston 11 is transmitted. The primary lines 48 connect the master cylinder to the primary space 50 in the wheel cylinder 52, Fig. 3, between the partition 60 and piston 58, and the secondary lines 23 connect to the space 51 between partition 60 and piston 59. In operation, initial movement of the master cylinder piston 11 in sliding over piston 13 pressurizes the liquid therebetween, which pressure is transmitted past valves 24, 25, thereby energizing the secondary pressure line 23. On further movement of the pistons 11, 13, valve joints 44 seat upon the inner ends of pistons 36 so that the four primary lines 48 are then sealed off from one another, the movement of such pistons 36 then pressurizing the primary lines to the four wheel cylinders. With a direction of drum rotation, according to the arrow F in Fig. 3, the drum friction acts to assist the hydraulic pressure in chamber 50, so that the shoes 55 and 56 are carried round thereby and a reaction pressure is created in chamber 51 and the secondary pressure line behind piston 59. The counter pressure forces piston 13 to move forward, liberating the " tail " 25 of valve 24 which closes abruptly under the action of the pressures above. In Fig. 5, an alternative arrangement is shown in which only the front wheel brakes of a vehicle are operated according to the invention. In another arrangement the secondary line 23 operates the rear wheel brake cylinders, the front wheel brake cylinders being operated in accordance with the invention. Fig. 12 shows the invention applied in principle to a disc brake. Primary fluid pressure is applied to span 124 by pipe 133 to engage friction linings 121 against the disc 120, the subsequent tangential movement of the support member causing movement of the piston 129 in its slidable mounting to react agairst the secondary line pressure applied at connection 23.

In one form, Fig. 1, two forme-inking rollers 2, 4 and a distributing-roller 6 are mounted in a sliding frame 7 and co-operate with a pair of distributing-cylinders 3, 5 mounted in fixed positions. The frame 7 may be moved from the normal position shown to a position in which the rollers 2, 4 are out of contact with the forme cylinder but still in contact with the cylinders 3, 5, and also a position in which all the rollers are separated from one another. In another form, Fig. 8, a single forme-inking roller 2 and a distributing-roller 4 are mounted on a pair of swinging side frames 7 and co-operate with a single cylinder 3 mounted in a fixed position. A damping- roller 12 and co-acting cleaning-roller 13 are mounted in slots 11 in the frames 7. Handlevers 19 pivoted to the frames 7 are connected by pins 20 to links 23 mounted on fixed pivots 22 and the levers 19 co-operate with notches 15 - - 18 in the frames 7 to hold the frame in four different positions. In the normal position shown, the levers 19 engage the notches 15. In the second position, the roller 2 is out of contact with the forme roller 1, but the rollers 2, 4 are still in contact with the cylinder 3 and the roller 12 with the forme roller. In the third position, the roller 12 is moved out of contact with the roller 1, but the rollers 2, 3, 4 are still in contact with one another. In the fourth position the rollers 2, 4 are separated from the cylinder 3. The links 23 are formed as flat springs and are perforated to receive the pins 20, so that by pressing back these links the frames 7 can be entirely removed by lifting them from their pivots 10.

Abstract: 1,261,446. Cathode-ray tube displays. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Feb., 1969 [16 Feb., 1968], No. 7912/69. Heading H4T. [Also in Division G1] Each of a plurality of N signals respectively representative of different physiological measurements is successively applied as a short duration beam brightening pulse to a line raster scanned cathode-ray display tube for the duration of I/N line scans in a cycle which repeats at the frame scan rate. As shown in Fig. 1, each of a group of six signals 13 derived from different physiological measurements is fed via switch means, operated in sequence, to an amplitude comparator 8 to which a sawtooth wave from the vertical (line) scanning generator 12 is also supplied. On amplitude correspondence between the two input signals a short duration output pulse is produced and this is fed via amplifier 11 to the beam intensity control electrode of the display tube 2. The switch means, which may comprise magnetic reed switches or electronic switches, are operated in sequence each for the duration of one sixth of the period of the horizontal (frame) scan by means of a time division scanner 16 supplied from the horizontal time base 18. The display produced thus consists of a horizontal trace having six steps each occupying one sixth of the width of the screen the vertical position of each step being a measure of the magnitude of the corresponding input signal. Further groups of signals 14, 15 specifying, respectively, upper and lower permissible limits for corresponding ones of the signals in group 13 are connected via respective switch means, operated synchronously with the switch means of group 13, to respective amplitude comparators 9, 10 also supplied with the vertical scanning sawtooth from generator 12 and providing outputs which are compared with the output from comparator 8 in a circuit 19 which, in addition to producing an indication on the display screen of the upper and lower limits in the form of respective luminous regions adjoining and extending away from the limits in opposite directions, also produces an "alarm field" in the form of a luminous region on the screen and may also operate an acoustic alarm signal. The circuit is so arranged that a "dynamic" signal such as an electrocardiogram or pulse waveform supplied at input 3 via amplitude comparator 7 is displayed at the upper portion of the screen whilst the other signals specifying blood pressure, temperature, respiration etc. are displayed on the remainder of the screen. A mask 20 (Fig. 2) provided with openings for the display and carrying six transparent vertical scale portions 21 is positioned in front of the screen.
