Title: Improvements in or relating to aircraft instruments
IPC: G01F9/02
Filed: 1953-11-10
Abstract: 747,358. Aircraft indicating instruments. KUZYK, W., and WHITTLEY, D. C. Nov. 10, 1953 [Dec. 16,1952], No. 31185/53. Class 4. An instrument unit to facilitate the economical operation of jet-propelled aircraft comprises a standard altimeter 10 and Machmeter 11 mounted on a panel 12. The altimeter has a needle 10a indicating altitude on a circular scale 10b and the Machmeter has a needle 11a indicating Mach number on a circular scale 11b, both scales being on the panel 12 and both instruments are connected by a pipe 13 to a static head (not shown) and the Machmeter is connected by a pipe 14 to a pitot head (not shown). A transparent disc 15, having a pointer 21 inscribed thereon, is mounted in front of the scale 10b by a bezel ring 16 which is enclosed by an annular rim 17 formed with a peripheral flange 17b carrying a scale 22 graduated in pounds representing the weight of the aircraft. The inner face of the ring 16 has bevel teeth meshing with a pinion 19 driven by a computer 23 which is electrically connected to a fuel-flow meter 24 and a counting device 25 responsive to the expenditure of ammunition or other disposable load. The Machmeter has a rim 30 and a bezel ring 29 similar to the elements 17 and 16 of the altimeter. The peripheral flange of rim 30 has a scale graduated in units of w/p. (weight of aircraft in pounds to atmospheric pressure in 1b/sq. inch) indicated by a pointer 27 on a transparent disc 28 secured in the bezel ring 29 and rotated by a computer 32. Knobs 26 and 33 are provided whereby the initial settings of the pointers 21 and 27 may be manually adjusted before flight. Although the Machmeter has been described as indicating on a single scale required variation of Mach number with w/p. it may be inscribed with a plurality of scales. To effect flight to obtain maximum range, the pilot sets pointer 21 to indicate on scale 22 the initial gross weight of the aircraft and the pointer 27 to indicate on scale 31 the value of w/p. obtained by dividing the initial gross weight of the aircraft by the atmospheric pressure at the airport. The pilot must then climb as rapidly as possible to cruising altitude and then fly the aircraft so that the altimeter needle 10a coincides with the pointer 21 and the Machmeter needle 11a coincides with the pointer 27. The flight path then takes the form of a gradual climb as the fuel is consumed. An alternative flight plan is described for flight at constant altitude. An alternative embodiment is described in which the scales and pointers of the Machmeter and altimeter are represented by two pairs of superimposed cross-lines which have to be maintained in coincidence.

Title: Improvements in or relating to hoists
IPC: B66B5/20
Filed: 1937-11-13
Abstract: 505,636. Catch - gear for platformhoists. PARKER, Ltd., F., PARKER, F. W., and THORNE, N. A. L. Nov. 13, 1937, No. 31240. [Class 78 (iii)] The guided platform of a hoist is locked to the guides automatically if the suspension rope breaks and can .be locked thereto by hand, for loading and unloading, by the same mechanism. When the suspension rope 10 breaks the sliding member 8a. and the levers 23 no longer support the pivoted levers 13 so that the springs 25 swing these levers clockwise and cause their cam shaped ends 19 to co-operate with the pivoted shoes 17 to bind against the guides 3. To apply the catches by hand to fix the platform for loading, a lever 31 is used which is pivoted to the levers 13 at 21 and connected to the levers 23 at 32. Movement of the lever 31 counterclockwise about the pivot 21 causes the point 32 to be moved correspondingly and thus swings the notched levers 23 counterclockwise until the notch 24 is clear of the pin 21. This releases the levers 13 from. the suspension gear, following which they are pulled down by the spring 25 to apply the cams and shoes to the guides. To re-set the mechanism, the lever 31 is restored and the hoisting-rope slackened until the notch 24 again passes over the pin 21. Rehoisting will then unlock the platform.

IPC: C25F3/04
Filed: 1959-09-21
Abstract: 907,264. Electrolytically increasing the surface area of metals. PLESSEY CO. Ltd. Sept. 19, 1960 [Sept. 21, 1959], No. 32012/59. Class 41. In electrolytically etching aluminium or other metal foils to increase their surface area a bi-directional current is used having a voltage wave cycle by far the greater portion of which is positive-going but which is such that successive positive-going portions are separated by short negative-going portions of considerably less amplitude than the positive-going, e.g. a cycle as shown in Fig. 1. At a given frequency there is an optimum value for the minimum voltage in a cycle. The etching may be carried out in a single step by passing the aluminium foil through an electrolytic cell in which it forms the anode, the cathode or cathodes of which is a plate or plates of aluminium. Possible electrolytes are HCl with dissolved A1 at pH 3.5; AlCl 3  solution with water added until the density is 1.005 g/ml.; the AlCl 3  solution with added HNO 3 . The aluminium, after being etched, is formed and aged at 500 volts D.C. in a solution of boric acid. It is stated that the method of etching is believed to be applicable to tantalum subject to the choice of a suitable electrolyte.
