Abstract: 584,968. Submarine mines. MIDGLEY, A. H., and HUSKINSON, P. May 11, 1940, No. 8536. [Class 9 (ii)] A floating mine, particularly for use in shallow waters, is secured to a sinker which is releasable in two stages, means being provided for automatically releasing the first-stage connection on impact with the water whereby the mine and sinker become spaced by a short distance, delay-action means being then operative to release the second-stage connection to increase the spacing between the mine and sinker. As shown, the sinker a is connected to the mine by a short cable b, and by a longer length, not shown. The short cable b is looped around a screw m in the head of a spring-loaded plunger c which is normally held retracted by connection to a gelatine or like soluble disc e, with or without additional soluble discs g according to the delay desired, a backing of cotton wool h and a perforated plate i being secured by a threaded thimble k. On release of the plunger c, the mine rises to the extent of the second (longer) cable. It is stated that the invention is applicable to mines of the kind described in Specification 583,788 and that the sinker may be normally attached to the mine by means such as described in Specification 584,967.

In one arrangement, members 502, 504 are moved in the opposite direction to member 503 by turning a cam 511. The three members are assembled to a body 501 by hollow, headed-members 505 secured by circlips 509, and cam 511 is biased by a spring 521 to close said openings. The body has end-grooves 528 ... 531 for engagement by arms 410, Fig. 1, on a magazine 411 for moving the carrier, with its component 401, from a holder 409 on a turret 412 to some other apparatus. Rods 420 hold the arms apart while member 408 is lowered to engage, with pins 418, the members 505, and in so doing depress the pins 417 into the holder. The ends of the arms 410 have points 419 which engage the vertical end-grooves 530, 531 to centralize the carrier on the arms. In another arrangement, gripping-members 605, 606, Fig. 5, are oppositely-movable between end-plates 601, 602 by a cam 623, and are guided by pegs 608, 610, respectively, engaging slots 609, 611 in the plates.

Abstract: 1294236 Anti-skid devices USTAV PRO VYZKUM MOTOROVYCH VOZIDEL 25 Feb 1970 [27 Feb 1969] 8998/70 Heading F2F A device for preventing wheel locking, in a motor vehicle, comprises a sensor sensitive to the angular lag of a wheel or wheels, and a servo-device and a two-way pneumatic valve 18 actuable by the servo-device and operatively effective on at least one wheel brake in dependence on impulses received from the sensor, the latter comprising two relatively movable parts 7, 8 hinged together by a rod 9. As shown, a shaft 5 carries a wheel 6 which, by means of a friction or toothed gear, is driven by rotation of the vehicle wheels or another member the speed of which is proportional to the speed of the wheels or the speed of the vehicle propeller or axle shaft, the shaft 5 mounting a plate 7 carrying a flywheel 8 rotatable about and axially movable along the shaft 5 and connected to the plate by a rod 9; the flywheel is also provided with a pin 10 which abuts a leaf spring 11. An extension 12 of the flywheel is engageable with the seating of a hole 13 leading to a chamber 4 divided by a diaphragm 14 and connected to a main brake valve via a calibrated hole 15. Upon the diaphragm is a plate 16 having an extension 17 for actuation of the pneumatic valve 18 having an inlet A for supply of pressure air from the main brake, an outlet for supply of the air to the brake cylinders, and an outlet C for exhausting air to atmosphere. In operation when the vehicle wheels tend to become locked resulting in braking of the plate 7, the flywheel continues to rotate with respect to the plate through a distance defined by a pin 19 and recessed plate 20 and the hinged connection by rod 9 between the plate and ' flywheel causes the latter to move longitudinally through a distance b whereby the hole 13 is closed resulting in the pressure in the chamber 4 lifting the diaphragm 14 to actuate by the rod 17 of the valve 18 which closes the air supply to the brake cylinders and connects the latter to atmosphere. The flywheel returns to the initial position thereof under pressure of the spring 11 to open hole 13 and permit the chamber 4 to be vented to atmosphere, the valve being returned to a position whereby air is again applied to the wheel brakes.
