Title: Improvements in or relating to photographic type-composing apparatus
Inventor: SHELLEY MELVILLE LESLIE
IPC: B41B17/34
Filed: 1962-11-01
Abstract: 992,757. Photographic type-composing apparatus. COMMUNICATIONS PATENTS Ltd. Oct. 25, 1963 [Nov. 1, 1962], No. 41352/62. Heading B6W. Photographic type-composing apparatus comprises a demountable stack of matrix rings, the character matrices of which lie on a cylindrical surface, and an optical scanner which is rotatable relatively to the stack of character matrix rings, for viewing the characters of a single matrix ring selected and movable axially relatively to the stack to select any one of the stack of matrix rings. In the apparatus described, the stack of rings 25, 33 is stationary and the optical scanner is rotated continuously about the axis of the stack. Each character matrix, carried by a flanged tubular element 26, Fig. 3, is formed as a mirror surfaced representation of the character with a matt black background. The element 26 has a slot 35 which co-operates with a pin 35 in an aperture 36 of the matrix ring. When the elements 26 are mounted in the apertures 36 of a matrix ring, the pins 35<SP>1</SP> are so positioned that the normal vertical axis of each character is displaced with respect to that of one of the adjacent characters by an angle of # 2#/N radians, N being the number of apertures around the periphery of the matrix ring. Connected for rotation with the optical apparatus is a known binary digital disc 24 having photo-electric sensing means 20-23, which enables the angular rotation, and hence the character viewed, to be determined at any instant. When the required character is viewed, a short-duration flash of light from a source 38 is reflected by a prism 7 on to the character matrix, which in turn reflects an image of the character on to photographic film via the refleeting prisms 7 and 11, lenses 8 and 12, a particular point-size lens 15 in the turret 14 and justifying and spacing apparatus (not illustrated). The optical scanner is continuously rotated by an electric motor 30 which is itself mounted on three screw jacks 19 used to raise and lower the optical scanner to select a particular ring. The justifying and spacing apparatus (not illustrated) comprise a mirror displaceable about its vertical axis. The setting of the mirror determines the lateral position of character images in sequence across the image plane. The setting of the mirror for each character is determined by the point size of character, the width of the character, the interward spacing, if between words, and the " leading " required for line justification. An alternative embodiment may have the optical scanner fixed and the stack of matrix rings rotating.

Abstract: 1,187,461. Respiratory apparatus. P. J. O'KEEFFE. 14 Sept., 1967 [24 Oct., 1966], No. 41969/67. Heading A5T. [Also in Division F2] A valve for use in artificial respiration apparatus and operable in response to pressures at a gas supply inlet, a gas outlet to the patient and an exhaust outlet to atmosphere, to interconnect the gas outlet with the exhaust outlet and with the gas inlet alternatively, comprises a valve body having a large bore portion 47 communicating with the gas outlet 49 and exhaust openings 50 and a small bore portion 55 communicating with the gas inlet (45) and the outlet 49 in which bore portions a large diameter portion 69, 70 and a small diameter portion 72 of a piston are reciprocable, respectively, an expiration valve (58, 59) being located in the exhaust outlet and adjustable magnets 80, 88 co-operating with magnetic members 69, 73 at each end of the piston for urging the piston towards its extreme positions of movement. With the piston held in the position for interconnecting the inlet (45, Fig. 7) with the outlet 49 via a chamber 56 and the small bore portion 55, by interaction between one magnet 80 and a magnetic member 73, the large diameter portion of the piston prevents communication between the outlet duct 49 and exhalation apertures 50 and inhalation may be induced. As pressure builds up in the patients lungs and the outlet 49 the piston is moved so that the interaction between the other magnet 88 and magnetic member 69 is increased and the piston "snaps over" to its other extreme position so that the small diameter portion of the piston disconnects the gas inlet (45) from the outlet which is then put in communication with the exhalation apertures 50 thus permitting exhalation. Reduced pressure in the outlet (45) at the end of exhalation causes further reversal of the piston under the influence of magnet 80 and magnetic member 73 for commencement of the next inhalation. The distances between the magnets 80, 88 and their associated magnetic members 69, 73 are adjustable for predetermining the pressures at which inhalation and exhalation are terminated. The expiration valve comprises a fibre water valve element (58 Fig. 9) which may be adjustably spring loaded.-The respiratory valve may be combined with a pressure reducer (Figs. 2-5) and a nebuliser..(Figs. 11 and 12).

IPC: B60T8/175
Filed: 1960-12-19
Abstract: 919,786. Fluid-pressure brakes. CATERPILLAR TRACTOR CO. Dec. 19, 1960, No. 43589/60. Class 103 (1). [Also in Group XL (c)] In a vehicle, e.g. an agricultural tractor, having a pair of ground-engaging wheels driven through differential gearing, a control device is provided in conjunction with separately-actuable brakes on the wheels which in response to a predetermined difference of speed of the wheels applies the brake of the faster wheel, so that should a wheel tend to spin, e.g. when on loose or wet earth, driving torque is maintained to the other wheel as a result of the application of the brake on the spinning wheel. As shown, wheels 17, 18 of a tractor are driven through half-shafts 15, 16 and a differential 14, and are provided with brakes 19, 20 operated by separate compressed air cylinders 37, 38. Air is supplied to the cylinders for normal braking by a driver control via conduits 41, and is also supplied automatically by solenoid valves 32, 33 controlled in response to said difference of speeds of the wheels, exhausting of air from the cylinders being effected by a pressure-sensitive relief valve when either supply is cut off. The speedresponsive control is effected by generators 22 driven by the respective wheels and having their outputs balanced by potentiometers 25, 26, as a result of which the bases and emitters of two transistors 27, 28 are maintained at the same voltage so long as the wheels are rotating at the same speed, so that the transistors do not conduct. When the speed of one wheel increases relative to that of the other wheel the corresponding transistor is made conducting and current flows via its collector to the appropriate one of two relays having contacts 29, 30. When the difference in speed of the two wheels is more than a predetermined amount this current is sufficient to operate the relay, which thereupon closes its contacts to supply current from a battery 31 to the appropriate solenoid valve 32 or 33 which applies the brake of the faster wheel.
