Title: Mechanism for controlling pitch-indicators for the instruction of aircraft pilots
IPC: G09B9/16
Filed: 1932-06-25
Abstract: 396,539. Training aviators. AIR SERVICE TRAINING, Ltd., JENKINS, H. F. and BERLYN, R. C., Hamble, near Southampton. June 25, 1932, No. 17977. [Class 4.] Apparatus for ground flying instruction comprises a pitch indicator the movable element of which is under the control of a dummy control column and a dummy throttle lever. A pitch indicator 10 comprising liquid in a tube moving over a vertical scale is connected by a rubber tube 13 to a reservoir 15 which can be raised and lowered to vary the reading of the indicator by a cable 16 connected to a drum 18. The drum 18 has a smaller drum 19 around which several turns of a cable 20 are passed. This cable has a counterweight 21 at one end and is connected at its other end to a weighted pulley 22, which lies in a bight of a cable 23 connected to an instructor's control column 25 and a pupil's column 26 so that movement of either column effects the reading of the pitch indicator. A dummy throttle lever 31, under the pupil's control, is connected to a piston 30 in an air cylinder 29 which is connected to a container 28 having a flexible connection 27 to the reservoir 15. Rapid movements of the throttle lever cause variations of pressure in the reservoir 15 and the effect of rapid accelerations and decelerations are simulated, but an adjustable leak 33 ultimately equalizes the pressure and also ensures that slow movements of the throttle lever do not affect the indicator. The column 26 and lever 31 may be connected to the lever shown, the central point 34 of which may be connected to a device for acting on the compass as described in Specification 396,538. Specification 396,540 also is referred to.

Title: Process for anodically cleaning and coating metal substrates
Inventor: MATTHEWS CYRIL GEORGE
IPC: C25D11/38
Filed: 1968-04-16
Abstract: 1,221,677. Coated metal substrates. C. G. MATTHEWS and R. G. MATTHEWS. 16 April, 1968, No. 17986/68. Heading B2K. [Also in Division C7] A metal substrate is treated such that an adherent polymer coating can be applied thereto, e.g. to produce a coated wire for fabricating into hooks and eyes for garments. A metal substrate, such as a wire, strip or sheet, is anodically cleaned and has a film containing Cr and Cu deposited thereon as it passes through an aqueous bath of chromic acid containing not more than 2% by weight of sulphuric acid and having therein copper in solid form. During part of the substrate's passage through the bath it is connected as an anode and during a later part it has no potential applied thereto, the Cr/Cu film apparently being formed during this later part. Fig. 2 illustrates treatment wherein wire is drawn at 16, anodically cleaned and coated with Cr/Cu in tank 18, rinsed at 23 and coated with molten nylon at 32; Fig. 3 illustrates alternative treatment following rinse bath 23 of Fig. 2. The wire is non-electrolytically coated with metal as it passes through a compartmented tank 49 containing solutions of metal salts. Vertical notch apertures 48 may be provided with "wipe-backs" of plastic foam or sponge rubber to minimise mixing of successive solutions. Subsequently the wire is electroplated in a similar tank 56 and drawn through a die 64. The drawing die box 63 contains a lubricant or a polymer or monomer solution which coats the wire, e.g. the solution may contain caprolactam which becomes polymerized to some extent during the drawing. A heavy plastic film may be extruded over the coated wire. In the case of strip or sheet, rolls are used in place of drawing dies 16, 64. Specified materials. The substrate may be ferrous or non- ferrous, e.g. bare or galvanised steel wire or brass wire. Metals which may be deposited from solutions of their salts non-electrolytically are Sn, Pb, Ni, Mn, Al or Cu; or Al/Zn which may be followed by either Sn/Ni or Sn/Ni/Cu. Metals which may be deposited electrolytically are Al/Zn from a sulphate bath, Cu from a fluoborate bath using a Cu anode, Zn from a fluoborate bath using a Zn anode, and Cu/Zn from a fluoborate bath. Cu and Zn may be deposited one after the other, (Example V). Plastic coatings may be of nylon, epoxy resin, acrylics, polyethylene or polypropylene. Metallic particles, e.g. Al powder may be distributed throughout the external plastic coating.

The tape guide 52 includes lateral guide flanges 95-(97), Fig. 3 (not shown), and a magnetic shield 60. The transducing region 53 is formed by a concave recess in the tape guide 52. The head assembly 30 is mounted on a threaded shaft 50 whereby the assembly may be moved axially from track to track, or may be swivelled to an inactive position contacting a cleaning brush (47), Fig. 1 (not shown). The capstan 18 may be integral with a flywheel (70), Fig. 3 (not shown), which is rigidly fixed on the rotor shaft of the drive motor. Alternatively, Fig. 6 (not shown), the capstan (111a) may be integral with the rotor shaft (111). To tension the tape 15 across the transducing region 53 the tape is driven at slightly different speeds at the rollers 20, 21 by constructing one or both rollers, and possibly also the capstan 18, in sections of different diameters. One roller, e.g. (132), Fig. 7 (not shown), may be sufficiently resilient to engage the capstan on either side of the tape. Possible arrangements are given in Figs. 7, 11, 13-16 (not shown). Where a reversible capstan drive is provided a manual or automatic arrangement may then be provided for interchanging rollers upon reversal of the drive, Fig. 12 (not shown). The above arrangement may be employed with reel-to-reel tape, possibly in a cassette or with endless tape cartridges. In the latter case, the rollers and the transducer head are mounted on a movable carriage, to permit looping of thetape around the capstan, which may be inside (Figs. 5; 17, 18) or outside (Figs. 9, 10) the cartridge. The rollers are themselves mounted on pivoted arms. An auxiliary tape drive (240)- (246), Figs. 9, 10 (not shown) may be provided to drive the tape to its initial loading position upon retraction of the movable carriage (225 away from the capstan (220).
