Abstract: 550,349. Internal expanding brakes. KIRKSTALL FORGE, Ltd., and COWELL, F. R. Sept. 4, 1941, No. 11321. [Class 103 (i)] Automatic adjusting means for brakes in which shoes are applied to a drum by a pair of shoe-carriers the shoes being capable of circumferential movement on the carriers so that the leading ends of the shoes abut on stops or on the ends of adjacent shoes, comprises a spring-urged wedges or snail cams adapted to increase the effective length of the stops or to be interposed between the adjacent ends of the shoes. A single shoe may be mounted on each carrier but the brakes shown are those described in Specification 550,348, comprising carriers 10 pivoted at one end 18 on an adjuster 12 secured to the back plate and movable apart at the other end by an expander 17, which and an adjuster 12 are such as described in Specification 542,112. Pairs of shoes 19, 19a are applied by the carriers through rollers 23 pivoted on the carriers and assuming the drum to be rotating in the direction of the arrow the shoes 19 abut on the stops 27 and the shoes 19a on the shoes 19. To reduce excessive clearance between the abutting ends 29, 29a of the shoes and between the shoes and the stops as the linings wear and which would otherwise occasion shock when the brake is applied. A stepped wedge-member 30 is slidably mounted in a casing 35 integral with each stop 27 and is urged towards the adjacent end 21 of each shoe 19a by a spring 32. When with the brake applied suffcient wear has occurred, a step of the wedge moves beneath the shoe end to take up the excess of clearance, the recess 131 formed in each step permitting the desired normal clearance when the brake is released. The wedge may instead be arranged between the abutting ends 29, 29a of the shoes but is then arranged to float circumferentially. In a modification, Fig. 5, each stop' comprises a snail cam 36 urged to turn counterclockwise on a pivot 37 by a spring 38 to engage a leaf-spring 125 on the end of each shoe 19a. The spring 125 ensures the slight normal clearance to be maintained since the spring 38 is unable to deflect it while .the shoe return springs are strong enough to do so when the brake is released. The ends of the shoes 19, abut on squared parts 50 mounted.on the pivots 37.

Title: Energy absorbing device for stopping a moving body
IPC: B64D1/14
Filed: 1955-04-21
Abstract: 793,541. Energy-absorbing elements. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU NORD. April 21, 1955 [July 24, 1954], No. 11549/55. Class 103 (1). In a mechanical device for absorbing, without restoring, the kinetic energy of a moving body, by causing a predetermined deceleration of the body, one or other of male and female members, movable relative one to the other, has an uneven surface while the other has a protrusion which is of sufficient strength and rigidity to deform or displace the protruding parts of the uneven surface when one is moved relative to the other by the impact against an obstacle. In the embodiment illustrated in Fig. 1, the male portion 1, consisting of a rod provided externally with a helical thread 2, is placed in a female portion 3 which comprises a hardened restricted portion 4. The female portion 3 is integral with the moving body so that when the latter reaches an obstacle the male portion 1 receives the force of impact in the direction 5 and deforming or displacing of the helical thread 2 by the restricted portion 4 occurs as shown at 6, thus absorbing the kinetic energy of the moving body. An alternative construction is shown in Fig. 2 wherein in the enlarged portion section 10 on the male portion 9 acts as the projecting member to act against an inner helical thread 8 formed in the female portion 7. An application of the embodiment illustrated in Fig. 1 is shown in Figs. 4 and 5 wherein a war missile 24 is attached to a parachute 25 and a device 26 similar to that shown in Fig. 1 is fixed to the lower end of missile 24. By suitable design of the profile of the helical threads or fluting, a uniform or variable deceleration of the body may be achieved. It is stated that the invention may also be applied to buffers on railway vehicles, car-bumpers, safety stops, deck landing arresting hook for carrier-based planes, parachutes and the recoil of a firearm.

Filed: 1970-03-11
Abstract: 1282332 Gloss sensing unit FAIRCHILD CAMERA & INSTRUMENT CORP 11 March 1970 [1 April 1969] 11690/70 Heading G1A A gloss sensing unit, Fig.1, is rendered independent of environmental contamination by using three separate radiation paths 10, 20, 30 formed by a common infrared source 21 together with three collimating lenses 11, 21, 31 and three sensing units 12, 22, 32, each including a focusing lens and a photo-diode, path 30 including a reflection by a gloss reference standard 2 in an enclosed chamber, and path 20 providing information for a measure of environmental contamination. Radiation in path 10 is directed via window 13 on to the moving surface 4 of the material (e.g. paper) whose gloss is being measured and thence via window 14 to sensing unit 12. Radiation paths 10 and 20 are exposed to the environment of the material 4 and so dust will eventually coat windows 13, 23, 14, 24. The signals from sensing units 22, 32, are fed into a differential amplifier A 1 , Fig. 5, and the signals from sensing unit 12 and from a tuning potentiometer are fed into a different amplifier A 2 ; the outputs of each amplifier being fed to a further differential amplifier A 3 . Initially the signal from unit 22 is adjusted by means of iris 25 till it equals the signal from unit 32, and initially potentiometer R22 is adjusted until it provides a signal equal to the signal from unit 12 (when a test sample is used in place of material 4). Variable resistor R25 is then adjusted until the output of A 3  is zero. When the gloss sensing unit is applied to the moving material 4 only signals proportional to variations of the gloss are processed; any signal variations due to environmental contaminants from units 22 and 12 cancel out one another at the differential amplifier A 3  stage.

A machine for grinding thin sections, such as rock samples for microscopic examination, comprises a frame 1 having a bearer plate 2 to which is fixed a section-holding system consisting of a section-holding plate 7 on a shaft 6 rotated by a motor 10, and a grindstone-holding system consisting of a shaft 11 which is parallel to the shaft 6 and has a grindstone 18 at its end, the shaft 11 being rotated by a second motor 19 and axially displaceable by a fine feed mechanism 16 controlling a nut and screw system 17 acting on the shaft to move the grindstone relative to the section-holder plate. The shaft 6 of the section-holder plate is mounted in bearings beneath the plate 2 which is inclined at an angle of approximately 10 degrees from the horizontal, the shaft being connected by a chain 9 to reduction gearing and a motor 10. The shaft 11 of the grindstone, which is driven by belts 22 from the motor 19, is mounted in bearings in a support movable along guides 14 on the under surface of the plate 2. The slide is displaceable to move the grindstone towards or away from the sectionholder plate 7 by the screw-and-nut 17 controlled by the fine feed mechanism 16. The mechanism 16 is operated by a connecting rod 23 which is, at one end, adjustably connected to a bush 24 on the shaft 6 of the section-holder plate, and, at the other end, formed with a slot 27 receiving a pin 28 on a lever 29 having a pawl 30 engaging a ratchet 31 connected to the fine-feed mechanism 16. The end of the rod 23 has a hook-shaped member 32 which, when retained in the position shown by a finger 34, transmits movement from the rod to the lever 29 to feed the grindstone towards the section-holder plate. The length of the finger is adjustable by a knob 36 so that the finger, which moves with the grindstone support, is retracted from the member 32 when the sections are of the desired thickness, the member swinging away from the pin 28 which then slides in the slot without moving the lever 29. During grinding, the sections are sprayed with water or petroleum through nozzles 42, 43 connected to a pump 41 and settling tank 40. The sections to be ground are first rough-cut with a saw and then stuck to glass plates which are adhered to the glass surface of the section-holder plate 7; suction may be applied to assist in holding the sections on the plate. The plate may have a transparent recess and a source of polarised light provided behind the plate so that a microscope can be used to assess the colour transmitted by the sections and determine their thickness.
