Title: Anti.lock brake control system
IPC: B60T8/70
Filed: 1972-02-17
Abstract: 1323539 Anti-lock brake control systems GENERAL MOTORS CORP 17 Feb 1972 [15 March 1971] 7335/72 Addition to 1231319 Heading F2F The present invention relates to an improvement of the invention set out in Specification 1,231,319. According to the present invention the "hold" mode of the braking pressure during an anti-lock cycle is effected by turning the on-off valve 44 for the brake pressure modualtor 52 on and off rapidly in alternating sequence. To this end the anti-lock brake control system is provided with a wheel speed recovery arrangement 74 which is responsive, in an anti-lock cycle, to a brake release signal and to the wheel acceleration signal to produce an oscillating signal when, in a brake-release condition of the system, the acceleration signal is within a predetermined range. The range is predetermined in the wheel speed recovery arrangement by a diode and a Zener diode and the oscillating output signal is produced by a multivibrator one input of which is connected to a reset flipflop (Fig. 2, not shown). The wheel acceleration, signal is also fed to a coefficient select circuit 66 which determines from the values of acceleration without skelding, obtained the coefficient of friction of the surface transversed by the wheel. The signal produced by the coefficient select circuit is fed to a threshold logic circuit 24 which is also fed with a signal from a wheel hop suppresion circuit 70. The threshold logic circuit 24 produces an input for a relative velocity intergrator 26. The threshold logic circuit provides a bias corresponding to threshold deceleration required during rotation of the wheel.

Title: Apparatus for feeding cores to a winding spindle in a cop winding machine
IPC: B65H54/14
Filed: 1956-03-09
Abstract: 790,814. Winding yarns; bobbins. OFFICINA MECCANICA BRUEGGER SOC. PER AZIONI. March 9, 1956 [March 10, 1955], No. 7385/56. Classes 120(2) and 120(3) Cop cones are fed to the winding spindle of a winding machine by apparatus comprising a magazine for a plurality of cones having means for feeding them one at a time to a receiver which is adapted to convey each core in turn to a supporting device which presents the core to the winding spindle and which is provided with magnetic means for retaining the core by the attraction of a magnetizable element secured to the core. A core A rotated by a spindle 12 is held by a magnetizable disc on its base on a magnet 26 in a socket 24 freely rotatable on bearings 25 in a bush 22 slidable under the action of a spring 37 in a sleeve 20 mounted on a carriage 10 slidable on rods 14. 16. When a cop has been completed, the spindle 12 is stopped and a shaft 44 rotated, e.g. bv a cam, thus rotating a lever 42 and arm 60 and bringing a stop 50 against the rod 16 to prevent movement of the carriage 10. A roller 40 on the lever 42 causes an arm 36 to pivot and through a pin and slot connection 38 34, rotate the bush 22 in the sleeve 20 and by abutment of the core A on the sleeve 20 release the core from the magnet 26. The movement of the arm 60 brings a receiver consisting of a shaped plate 66 and spring blade 70 and containing a fresh core A, from below a magazine 74 towards the sleeve 20. At the same time a feed lever 88 disengages from a lever 82 so that a trough 78 at the base of the magazine 74 is rotated by a spring 84 through half a turn so that a new core A falls into the trough 78. The spindle 12 is now caused to move away from the sleeve 20 and withdrawn from the cop B so that the cop falls for example into a collecting shoot. The shaft 44 now rotates further and causes the receiver to bring the fresh core A into alignment with the socket 24. The roller 40 moves along the arm 36 and runs off the end, when the spring 37 returns, the parts to the position illustrated and the new core A is attracted and held by the magnet 26. The shaft 44 now returns to its initial position, which removes the stop 50 and allows the carriage 10 to move under the action of a counterweight on a chain 18 towards the spindle 12. The lever 42 and arm 60 return to the position illustrated, and the lever 88 engages the lever 82 to invert the trough 78 and discharge the core A therein into the receiver. The core is engaged on the spindle 12 and winding recommences.

Abstract: 1416909 Stripping cables PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 Feb 1973 [18 Feb 1972] 7448/73 Heading H2C An arrangement of knives 11, 13 and blades 37, 39, 41 strips and profiles the end of a coaxial cable as shown. The cable end is first inserted into a bore 5 as far as a shoulder 83. A knife 11 cuts through the sheath and outer conductor at 85 and a knife 13 cuts through the sheath at 87. The stripped end is then inserted into a narrower bore 7, where one or more blades 37, 39, 41 profile the end of the dielectric. Handles 61 allow the device to be rotated to perform both cutting operations. The knives 11, 13 are adjustably mounted by screw sleeves 29 in a block 9 which can be retracted by a handle 15. The block 9 is held in the retracted or operative position by a spring- loaded pin 19 engaging a recess 23 or 21 respectively. The cutting edges 27 are eccentric to the knife bodies 25, so that as the cable is pulled out of the bore 5 the knives rotate and then make longitudinal cuts. The blades for profiling the dielectric are mounted on arms 43, 45 pivoting on a shaft 33 (Fig. 3). The arm 43 is spring-urged to a position set by an adjustable stop 55 and carries blades 41 and 39 for profiling sections 105 and 107 respectively. The arm 45 is initially locked to the arm 43 by a pin 47, and carries a blade 37 which partially removes the end section of the dielectric, beyond the section 107. The pin 47 is then withdrawn, the arm 45 pivots further to an extent limited by a finger 63 engaging the outside of the dielectric and the blade 37 removes the rest of the end section. Two cable ends prepared as above may be joined as described and claimed in Specification 1,415,897.

Abstract: 611,931. Magnetrons. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 12, 1946, No. 7746. Convention date, Feb. 6, 1945. [Class 39 (i)] [Also in Group XL (c)] Ultra-short waves transmitted by a waveguide are modulated by de-tuning a resonator coupled to the guide, the modulating-voltage being applied to a space-charge valve of the magnetron type, to vary the effective capacity in the resonator circuit. As shown, a wave generator E feeds a wave-guide G which is branched at Q to form two guides 1, 2 leading respectively to a radiating horn K and to an absorbing termination F1, R, P1. Coaxial-line resonators L1, L2 are coupled to the guides 1, 2 by condensers S, the outer ends being terminated by the cylindrical anodes and axial cathodes of magnetron valves M1, M2. Modulating voltage is applied in complementary or push-pull fashion to the condenser plates S and thus to the magnetron anodes. The magnetrons M1, M2 operate in a magnetic field of such strength that the space charge electrons resonate at a frequency close to that of the transmitted wave; under these conditions, the apparent capacity of the magnetrons varies rapidly with their anode potential, and in consequence of the de-tuning of the resonator L1, the wave transmission to the horn K is varied in the rhythm of the modulating voltage.
