Abstract: 1503850 Energy storage employing metal hydrides UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINSTRATION 23 July 1976 [19 Aug 1975] 30848/76 Heading C1A [Also in Divisions C7 and F4] A method for storing energy comprises: (a) heating a first "metal" hydride 16 to an "effective decomposition temperature", said hydride having a decomposition pressure of 100 to 2280 mm of Hg at temperatures of from 100‹ to 300‹ C. and a standard heat of formation of 12 to 17 kilocalories per mole of hydrogen, whereby said hydride absorbs thermal energy and decomposes to form a first hydridable "metal" and hydrogen gas; (b) contacting the hydrogen gas with a second hydridable "metal" 22 while maintaining said second metal at a temperature below the "effective decomposition temperature" of the "metal" hydride being formed, thereby forming a second "metal" hydride, said second hydride having a decomposition pressure of from 760 to 2280 mm Hg at a temperature of 0‹ to 25‹ C. and a standard heat of formation of from 25 to 75% that of said first "metal" hydride per mole of hydrogen, whereby thermal energy is released as said hydride is formed; and (c) recovering said thermal energy. The stored energy may be released by: (d) cooling the first hydridable "metal" to a temperature below the "effective decomposition temperature" of the first "metal" hydride; (e) supplying heat to the second "metal" hydride to maintain said hydride at an "effective decomposition temperature" whereby said "metal" hydride absorbs thermal energy and decomposes to form a second hydridable "metal" and hydrogen gas; (f) contacting the hydrogen gas with the first hydridable "metal" while maintaining the first "metal" at a temperature below the "effective decomposition temperature" of the hydride being formed, thereby forming a "metal" hydride and releasing thermal energy; and (g) recovering said thermal energy. The term "metal" pertains not only to single metals but also to suitable alloys. The "effective decomposition temperature" is the temperature at which the "metal" hydride to be decomposed releases hydrogen gas at a usable rate. The first metal hydride may be heated indirectly using a solar energy collector 10 and a heat transfer loop 12, or directly either in a sealed container acting as a flat plate collector irradiated by sunlight, or by residual heat in stack gases. The first "metal" hydride may be MgNiH 4 . The second "metal" hydride may be LaNi 5 H 6-7 , SmCo 5 H 2À5  or FeTiH 1À95 .

Title: Automatic brake adjusting means
IPC: F16D65/18
Filed: 1966-07-08
Abstract: 1,141,212. Automatic wear adjustment device for brakes; hydraulic brakes; ratchet clutches. SOC. ANON. D.B.A. 8 July, 1966 [12 July, 1965], No. 30880/66. Headings F2C, F2E and F2F. In an automatic wear adjusting device, particularly for a disc brake, a screw - and - nut adjustment provided by a screw 74 and a threaded sleeve 72 is effected through a oneway clutch unit provided by a cage 86 located in the end of the sleeve 72, the cage 86 comprising slots 90 provided with inclined ramps in which are located balls 88 such that when the cage is moved in a direction corresponding to the direction f under the action of a torsion spring 102, the balls 88 and slots 90 define a freewheel connection between the cage 86 and the sleeve 72, the return force of the torsion spring being opposed by a one-way driving connection in the form of a stud 96 and fixed to a plate 68 which is actuated when the brake is applied by fluid under pressure being supplied between a diaphragm 62 and the chamber 46. As shown in Fig. 2, when fluid under pressure is introduced through a port 40 into the chamber 46, the caliper housing 26 is moved by reaction to the right, as shown in the drawings, to apply a friction pad 50 solid with the floating caliper housing against one face of a rotatable brake disc 16, the other friction pad 52 being applied directly by means of the diaphragm 62, urging plate 68 towards the brake disc, to urge the threaded sleeve 72 and the screw 74 in a similar direction to apply an axial projection 78 on a collar 76 against a pressure plate 60 to urge the other friction pad 52 against the rotatable brake disc 16. As stated above, the stud 96 fixed to the plate 68 moves towards the interior of a slot 94 in the cage 86 of the freewheel to cause the cage 86 to move in a direction opposite to the direction indicated by the arrow f to de-clutch the freewheel. When the brake is moved to its release position the frictional effect between the screw 74 and 72 is reduced and the stud 96 is disengaged from the slot 94 such that the torsion spring 102 which has been biased or loaded upon the application of the brake urges the cage 86 in the direction indicated by the arrow f to clutch the freewheel. The sleeve 72 then rotates to unscrew from the screw 74 to adjust for wear of the friction pads. Provision is made for application of the brake by means of a hand brake mechanism connected to an annular member 108 through ball and inclined ramp mechanisms. A flexible boot 126 protects the hand brake ball and ramp mechanisms from extraneous dirt (Fig. 5).

Abstract: 633,555. Moulding concrete articles. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. Oct. 18, 1946, No. 31072. Convention date, Nov. 6, 1945. [Class 87 (ii)] Concrete articles such as railway sleepers and beams which have to be shaped accurately are first moulded in any manner and then, after being removed from the mould before the concrete has completely hardened are subjected to compressive stress to modify and correct their shape, pressure being maintained until the concrete has completely hardened. Thus, in a concrete bracket 1 (for a railway sleeper) the angular disposition x of the face 6 and the distance b between a sole plate 2 and the face are to be reproduced with accuracy. To apply the required stress a plate 8 is fixed in the 'correct angular position (i.e. x = 90 degrees) to a rod 7 which is passed through a hole 5 in the bracket and carries a nut 10 and washer 9 at its opposite end. The nut is tightened until the distance b is correct. In the hollow beam 11, Fig. 2, the length l and the angular disposition of the faces 12, 13 are corrected by means of plates 16, 18 fixed respectively to a tube 15 and a rod 17 telescopically engaged. Nut 19 is tightened until the tube 15, which acts as a gauge, abuts the plate 18. The plates 8, 16, 18 conform to the desired contours of the faces they lie against, which are not necessarily flat.

Abstract: 1347827 Measuring absorption photoelectrically MILTON RAY CO 5 July 1972 [29 Nov 1971] 31441/72 Heading G1A [Also in Division G2] In an apparatus for the simultaneous measurement of the optical properties of at least two materials, e.g. liquids flowing through respective cells 50, 52, in which both materials are irradicated by at least two radiation sources 64, 66, each radiating in a different wavelength region, a mirror 72 directs radiation from the materials to form a plurality of images at 76, 80, one for each wavelength, whose intensities are compared to derive a measure of the optical properties. Radiation from a Hg vapour lamp 60 illuminates a diffusing screen 62 having a phosphor coating 66. This coating converts the 2, 540  Hg resonance wavelength to 2, 800 , and hence the screen acts as two sources of different wavelength. Lenses 68, 74 and mirror 72 are so placed in the optical path that photo-cell pair 76a, b receives only 2, 800 A that has passed through both samples, whereas photo-cells 80a, b receive only 2, 540 from the samples. Filters 78, 82 are provided. Each photo-cell pair is arranged in a bridge circuit, Fig. 5 (not shown) whose out-of-balance current comprises the measurement signal and is recorded. The difference between the measurement signals at the two wavelengths is also recorded. A feedback loop maintains a constant light source intensity. Typically, the apparatus is used for monitoring the output of a chromatographic column, but it may also be used for investigating solids.

Abstract: 1,193,226. Cam-operated switches. EASTMAN KODAK CO. 3 July, 1968 [7 July, 1967], No. 31649/68. Heading H1N. [Also in Divisions F2 and G2] A cam mechanism, particularly for operating a switch controlling film or paper free loop feed or take-up in a photographic printer, comprises a reciprocatory, sliding, face, or, as shown, radially acting cam 34 having successive surfaces 47, 54, 55, and a switch member 37 biased towards the cam by its resilient support arm 35 and carrying, respectively fixed and pivotable thereon against a spring bias, sliding or, as shown, roller followers 38, 40. In operation, when the cam is rotated clockwise from the broken line position shown in Fig. 2, the follower 40 is deflected by the surface 55 into an inoperative position and the member 37 remains in its lower position shown in Fig. 2 until the surface 47 engages the follower 38 to raise the member 37 to close a switch 51, 52 and to allow the follower 40 to be sprung into a position normal to the surface 54. When the cam is thereafter rotated anti-clockwise, the follower 40 is maintained in its spring held Fig. 3 position so as to prop the member 37 in its switch closing position despite the withdrawal of the surface 47 from the follower 38, the member 37 only returning to its lower, switch opening, position when the follower 40 engages the surface 55. In the photographic printer shown in Fig. 1, a web 11 of film or paper extending between supply and take-up reels 12, 13 is frictionally intermittently advanced by a capstan 15 past an exposure area in a web portion 14. First and second free loops 17, 18 are provided to maintain the portion 14 under slight constant tension and to eliminate inertial influences. In respect of the loop 17, a sensing arm 19 carries a roller 22 bearing on the loop inner surface under the load of a weak spring 23 so that the size of the loop determines the position of the arm 19 and hence the position of the cam 34 fast with the arm. The switch 51, 52 is in series with a motor 25 intermittently driving a loop controlling capstan 24. When the loop decreases to move the arm 19 to the broken line position shown, the switch 51, 52 is closed to energize the motor 25, the switch then remaining closed as the loop enlarges until the arm returns to the solid-line position shown when the switch is opened. A similar cam/switch arrangement is provided for the loop 18.

Abstract: 535,124. Automatic volume control. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and TERRONI, T. B. D. Dec. 11, 1939, No. 31923. [Class 40 (iv)] In a carrier signalling system the level of a pilot current is investigated periodically and controls the setting of two attenuation adjusting switches in turn, each switch being ineffective while it is being set and taking over from the other at the completion of the setting operation. As shown the level of the pilot is shown in decibels on a meter RM which, as described in Specifications 441,881, 441,999, [both in Group XXXVIII], and 460,187, [ Group XXXVI], controls the number of teeth of a comb member to be scanned by a light beam and therefore the number of impulses to be given with the aid of a photo-electric cell to a relay IMP. Assuming both switches to be in their normal positions, the impulses of the first scanning operation are delivered to magnet AM of switch A. At the end of the train relay P which pulled up at the first operation of A energizes COA to make the setting of A effective in adjusting the attenuation of the line and to switch the impulse circuit to magnet BM of switch B. It also energizes COY which is followed by RB. The next impulse series steps switch B in a similar way, Q remaining held during the train and then falling back to energize COB. This shunts out COA to make switch B effective in controlling the attenuation, sends switch A home and releases COY. When A reaches normal, COX pulls up energizing RA to remove the shunt from COA in readiness for the third series.
