Title: Improved reflecting telescope
IPC: G02B23/00
Filed: 1963-12-31
Abstract: 1,104,297. Reflecting objectives. A.H. HALE. Dec.2, 1964 [Dec.31, 1963 ], No.51265/63. Heading G2J.  In a reflecting telescope having a concave primary reflector and a co-operating viewing means, the primary reflector is only a segment of that used in the corresponding primary reflector of a normal telescope. As shown applied to a Gregorian telescope, Fig. 2, the primary reflector is cut across a diameter and the two segments A, B are separated by a distance D s <SP>+</SP> which is slightly greater than the diameter of the secondary reflector. The latter is also cut across a diameter and each half a, b, is moved in the same direction, and by the same amount, as the primary segment with which it co-operates. Consequently the severed edges 11a, 12b of the secondary segments lie outside the uncut edges. The images formed at Fa' and Fb' may be combined for monocular  viewing through an eyepiece, or separate eyepieces may be used so that binocular viewing is provided. The telescope is shielded from extraneous light by providing an enclosure having a central partition extending along the central plane of symmetry and sidewalls which extend between the cut surfaces 11 and 11a and between 12 and 12b respectively, with small apertures in the regions of the primary foci F A , F B . The telescope may consist of only one of the two systems A, B. As applied to a Newtonian system, Fig. 10 (not shown), the inclined viewing reflector may be made smaller than normal and placed nearer to the focus of the concave reflector so that obstruction of the incoming rays is avoided. A pair of such systems may be combined for monocular or binocular viewing. As applied to a Herschelian system, Fig. 15 (not shown), the inclination of the concave reflector may be less than normal so that distortion is less than when a full normal reflector is used.

Filed: 1965-12-03
Abstract: 1,173,141. Measuring weight, electrically C.D. BOADLE, R.A. ATKIN [trading as WESTERN PRECISION EQUIPMENT] . Dec. 5, 1966 [Dec. 3, 1965], No. 51450/ 65. Heading G1N. In a weighing apparatus wherein a load representative signal voltage from a resistance strain gauge load cell circuit is automatically balanced by a voltage signal from a servomotor driven potentiometer coupled to an indicator, and wherein the load cell and potentiometer output characteristics do not correspond, e.g. wherein the output characteristic of the potentiometer is linear over the applied load measuring range, while that of the load cell is non-linear Fig. 1 (not shown), the output characteristic of the potentiometer is continuously varied so that it conforms to the load cell characteristic and thus the inidcator accurately represents the applied load. The variation is achieved by angular movement of the potentiometer body, thereby moving the balance point position physically relative to the potentiometer wiper, while the wiper is also being moved by the servomotor until the system is balanced. The wiper is directly coupled to the servomotor and the potentiometer body is moved by a radius arm 22, Fig. 2 , fixed thereto and having adjustable follower 20, 21 for zero adjustment, which rides on a cam 16 on a spindle 18 driven by the servomotor via reduction gears 17, 19. The geometry of the cam surface determines the configuration of the potentiometer output characteristic and is arranged to provide the same configuration as that of the load cell output. The weight measurement may be recorded.

Abstract: 1402929 Change-speed control FORD MOTOR CO Ltd 9 Nov 1972 [12 Nov 1971] 51720/72 Heading F2D In an automatic transmission on a motor vehicle, shown as a torque-converter-driven Simpson planetary gear set providing two reduced ratios, direct drive and one reverse, established by friction clutches 30, 32 and brakes engaged by fluid pressure controlled by shift valves actuated by opposing fluid pressures responsive to output speed and engine torque, the engine torque signal is derived mechanically by a cam-and-ball series connection 118, 120 between the converter turbine shaft 56 and the input member 106 of the gear, such connection actuating a valve 132, 134, which regulates a torque-responsive fluid pressure acting on the right face 110 of a piston 112 providing the feed-back reaction for the camball connection and also the torque signal pressure. The series connection is provided by the balls 118 connecting a grooved inner member 124, splined ta 80 to the turbine shaft 56, to the grooved outer skirt 114 of the piston 112, which is, in turn connected by the balls 120 to a grooved member 128 secured to the gear input member 106, which is the common input drum of the forward and driect-reverse clutches 30, 32 of the gear. The grooves for the balls 118 are plain axial, whilst those for the balls 120 are helically inclined to produce a rightward torque thrust on the piston 112 in forward drive which applies a torque responsive relative turning movement between the members 106, 124 and a relative axial movement between the member 124 and the piston 112. The former movement actuates a rotary valve formed by a central extension 134 and a sleeve 132 on the respective members 106, 124, the extension 134 having a diametral port 236. Line pressure in all forward ratios is supplied to a passage 140 communicating with the forward clutch-engage cylinder 106 through passages 138, 136, 156, and 154. The rotary valve port 236, under torque loading, is turned out of register with ports 146, 148, leading to exhaust through a passage 131, and into register with ports 142, 144, leading to the line pressure passage 136, the valve port 236 also leading through a passage 150 to the right face of the reaction piston 110, to provide a reaction feed back to the torque load and thereby regulate a torque responsive pressure, which is used as a torque signal for control of the transmission shift valves. In Figs. 5 and 6, not shown, additional pressure chambers are provided for the piston 112 to balance centrifugal liquid pressure.

Title: Improvements in or relating to regenerative furnaces
IPC: F28D17/00
Filed: 1967-11-14
Abstract: 1,243,185. Thermal regenerators. PILKING- TON BROS. Ltd., J. E. HALL, W. CHARLTON, H. C. WYNNE, and L. A. NEVARD. 8 Nov., 1968 [14 Nov., 1967; 6 Nov., 1968], Nos. 51778/67 and 52576/68. Heading F4K. In a regenerator 20 comprising a fluid-pervious bed 25 of rubble through which the heat exchanging fluids pass alternately, a method of operation consists in continually removing rubble from the lower region of the bed, sieving said rubble to remove fine material therefrom, and then returning said rubble to the upper end of the bed. The glass making furnace shown has two of the regenerators 20 fluid flow through which is controlled in the conventional manner by reversing valves 19. In each regenerator the bed is supported on grate portions 23, 24 disposed so as to provide an opening 26 sufficiently large to permit rubble to gravitate therethrough towards an opening 30 when periodically a door 32 is opened and a shaker 35 manually operated. Fine material in the rubble falls through perforations in the grate portion 23 to the bottom of the regenerator chamber whence it is sub sequently removed through a door 36. The fine material may, for example, be carry-over from the furnace gases or small pieces of rubble produced by abrasion. The withdrawn rubble is returned by a conveyer (not shown) to the top of the bed via an opening 38. An alternative form of grate (Figs. 3, 4) consists of parallel bars (52) of circular or non- circular cross-section linked together so that they can be simultaneously and continuously oscillated by an hydraulic piston (57) to cause a steady flow of rubble through the grate on to a sieve (60) sloping towards the outlet opening 30 from which the rubble is removed, fine materials from the rubble passing through the sieve as in the first embodiment. In a further embodiment (Fig. 5) also having oscillating grate bars, these are arranged in two groups (87, 88) at different levels above a chamber (94) with perforate walls (196) for sieving the rubble. Sieved rubble from the chamber (94) is reintroduced into the bed through a hopper (80) at the upper end of the regenerator to one side thereof whereby the incoming rubble forms an inclined surface (97) opposite the exhaust gas inlet (82) to the regenerator and so protects the regenerator wall against erosion by the hot gases. In this arrangement the rubble is to some extent preheated in the hopper before re-entering the bed so reducing thermal shock.
