Title: Improvements in or relating to the stiffening of boot or shoe parts
IPC: A43D95/12
Filed: 1936-11-12
Abstract: 486,956. Stiffening boot &c. uppers. BRITISH UNITED SHOE MACHINERY CO., Ltd., and BRAY, W. N. Nov. 12, 1936, No. 30851. [Classes 17 (i) and 17 (ii)] A shoe upper particularly a Veldtschoen sandal at the toe end is stiffened by a layer of cellulosecompound material such as celluloid, which after it has been softened is applied to the shoe upper and is then further treated with a liquid softener to cause it to adhere at the margins and through perforations in the stiffener to the flesh side of the upper. Apparatus for softening shoe stiffener blanks may comprise a casing 10 in which the level of solvent is maintained constant and a blank holder 38 carried on a shaft 34 provided with an offset weight 58 which tends to swing the framework outwardly through an opening 12 in the casing to loading and unloading position but which movement is prevented by a camplate 60 inside the casing which contacts with a roll 62 on the shaft 34 unless the shaft is in the fully raised position shown. A spring-closed member 14 closes the aperture 12 when the holder 38 is withdrawn to blank-softening position inside the casing by manual operation of the handle on the shaft 34 against the action of a spring 56 acting on one side of a lever 48 attached at one end to the shaft 34 and pivoted on the casing. A hydraulic check, set by an adjustable valve 66 which controls the return flow of liquid through a transfer duct 68 in the side of a cylinder 52 from below the piston 54 to above it, controls the speed of descent of the piston 54 and of rising of the shaft 34 when the handle thereon is released, to control the period of immersion of the blank in the solvent. An intermediate port 70 connecting the duct 68 to the cylinder permits free transfer of liquid during the last part of the rise of the shaft 34 to move the holder 38 quickly upwards after the blank has been lifted clear of the solvent in the trough 20 of the casing 10. As the shaft 34 and holder 38 reach their highest positions the weight 58 causes the holder to push open the cover 14 to present a softened blank for unloading. The holder 38 comprises a framework in upper and lower parts between which the blank is inserted and carries a plate 46 to close the aperture 12 in the casing 10 when the holder is in loading position. Specification 368,756 is referred to.

Title: Pitch controls for automatic landing
IPC: G05D1/06
Filed: 1962-08-14
Abstract: 997,707. Automatic control of aircraft. LEAR SIEGLER Inc. Aug. 14,1962 [Oct. 30,1961], No. 31083/62. Heading G3R. [Also in Division B7] In a system for automatically controlling the pitch of an aircraft during landing, electrical signals dependent on the rate of descent, pitch altitude and pitch rate are combined to oppose a signal dependent on vertical deviation from a radio beam and a further signal which is progressively modified after a predetermined altitude is reached. In Fig.1, prior to an aircraft commencing a radio glide path descent, a potentiometer unit 16 is manually set to produce a signal which is applied through a potentiometer 24, set at maximum, and a summation unit 35, to the pitch channel of an autopilot (not shown) to give an angle of descent equal to that of the glide path. Thereafter, vertical deviations from the centre of the glide path are detected by a radio receiver 10, signals from which are applied through a potentiometer 12, also at maximum, to control a servomotor 15 adjusting potentiometer 16 to restore the aircraft to the glide path. Rate feedback is provided by a tachometer generator 18 associated with motor 15 and feedback from potentiometer 16 is provided through a wash out filter unit 21. Damping is provided by the addition of signals from a rate of pitch gyro 40, signals from a pitch altitude detector 36 applied through a further wash-out filter 37, and signals from a barometric rate of descent detector 28 which are combined with signals from a vertical accelerometer 30 in such proportion as to compensate for phase shift due to a lag network 32. When the aircraft has descended to a predetermined altitude, e.g. 200 ft, a radar altimeter 27 commences to operate potentiometer 12 so that, during descent to a lower predetermined altitude, e.g. 50 ft, the signals from the glide-slope receiver 10 are progressively reduced to zero since they become unreliable. During the remainder of the descent, altimeter 27 progressively decreases potentiometer 24 to a 20% setting so that the descent is flattened out for landing. In a modification, amplication and Zener diode limiting is applied to the signals from the glide path receiver which are applied through potentiometer 12 directly to the autopilot instead of controlling potentiometer 16. Above 200 ft potentiometer 16 is controlled by signals from rate of descent detector 28 in readiness for switching into the control system at that altitude by altimeter 27.

N-type epitaxial layer 34 having graded impurity concentration may be chemically etched at the exposed regions prior to the anodic oxidation which is either a controlled one below the breakdown voltage of an anodic film initially formed and which results in preferred anodic oxidation, and thereby increased swelling, at the edges of openings in the dielectric layer 40 Fig. 10 (not shown), or is a rapid one caused by the application of a voltage high enough to break down the anodic film initially formed so as to convert the entire exposed region into a porous anodized material. The porous anodized material is hardened during subsequent heating steps involved in the diffusion of base and emitter regions 52, 54 respectively, which process step also results in the formation of an oxide film 64. P-type impurity may be diffused through the porous anodized silicon into the N-type epitaxial sub-layer (38) to form the regions 65 during the formation of the oxide film 64. Alternatively p-type impurity is introduced into the electrolyte during the anodization. Encapsulation of an integrated circuit comprising isolated transistors with individual external connections for the emitter, base and collector is described, Fig. 9 (not shown).
