Title: A range determining device
Inventor: FREELAND STANLEY RALPH
IPC: G03B3/00
Filed: 1969-07-24
Abstract: 1,215,677. Focusing arrangements. BELL & HOWELL CO. July 24, 1969 [Aug.28,1968], No.37270/69. Heading G2A. In a camera of the type disclosed in Specification 1,208,388, in which the position taken up by a freely swinging pendulous member when the camera is pointed at the foot of an object to be photographed adjusts the focus accordingly Fig.1 (not shown), the pendulous member can also be positioned manually. As shown, the pendulous member 34 swings freely under gravity on an axle 36 as the camera is tilted, and its lower end is shaped as a pointer 38 which reads over a distance scale (42), Fig.1 (not shown). The lens barrel 20, which can move axially for focusing adjustment, has a pin 28 extending radially from it. Pin 28 engages in a cut-out 58 in an actuator member 52, pivoted at 54 and urged clockwise by a spring 60. Thus pin 28 is urged against the cam surface 66 of member 34, the said surface being computed so that the lens is in focus when pin 28 is in contact with it (e.g. in any inclined attitude, as in Fig.1). If it is desired to focus the camera manually, an external knob (70), Fig.3 (not shown) is provided for the purpose. The knob turns a coupler plate 74 which also pivots on axle 36, the plate carrying a stud 72. In the position of Fig.2, stud 72 rests in a pocket 94 of an arm 88, the arm being pivoted on at support 90, and urged anti-clockwise (i.e. into contact with stud 72) by a spring 92. To condition the arrangement from automatic to manual focusing, the knob (70), and hence plate 74, is rotated anti-clockwise. Stud 72 moves out of pocket 94, and rides up the inclined end 96 of arm 88 as this arm is moved downwards by spring 92, until a tongue 98 extending from arm 88 engages an upper edge 100 of member 34 (Fig. 5). Further rotation of the knob (70), and hence plate 74, brings stud 72 into contact with the other upper edge 104 of member 34. Still further rotation of plate 74 causes stud 72 to push member 34 anti-clockwise, so forcing arm 88 upwards again against its spring 92, Fig.6 (not shown). Member 34 is thus being moved under control of pressure on it in both  directions. The knob is turned until pointer 38 indicates the previously determined distance on the scale (42).

Abstract: 1,134,482. Manipulating apparatus. SCHLOEMANN A.G. 24 Aug., 1966 [3 Sept., 1965], No. 37930/66. Heading B3M. Manipulating and straightening apparatus for rolled stock includes a pair of beams 3 and 4 which are adjustable transversely of a roller table 1 to align stock with a rolling mill and to straighten the stock. The beam 3 is mounted on supports 6 which extend beneath the beam 4 and its supporting bars 11. Rotation of toothed wheels 8, which co-operate with racks 9 on the supports 6, shifts the beam 3 together with the beam 4 laterally. The beam 4 is moved relative to the beam 3 and supports 6 by hydraulic cylinders 10 which are mounted on a crosshead 14 and act against a bar 11. A mechanical linkage, which includes pivots 23 and 23a on the bars 11, equalizes any pressure difference suffered by the ends of the beam 4. In operation, after appropriately positioning the beam 3 by the wheels 8, the beam 4 is moved under low hydraulic pressure towards the beam 3, and is then urged under high pressure against the rolled stock to straighten it. Pivoted tilting arms 15 can then be operated by a cylinder 19 to turn the stock into the correct position for further rolling.

Abstract: 862,314. Finishing yarns; twist-tubes. HEBERLEIN & CO. A. G. Nov. 26, 1958 [Dec. 6, 1957], No. 38146/58. Classes 120(2) and 120(3) A bulked yarn is produced, without the use of heat, by leading a pretwisted yarn of continuous filaments e.g. of polyamides, polyesters, vinyl- or acrylic-polymers, regenerated cellulose, cellulose acetate or mixed filaments thereof, through a false-twisting apparatus having a rotating part on which false-twisting is effected and the yarn is thus, at least temporarily, back-twisted: the frictional contact of the yarn on the rotating part and/or air vortex effects created by the rotation cause simultaneous loop formation and filament distortion. As shown, yarn is led from rollers FR to a false-twist shaft FT at an acute or obtuse angle B to the axis thereof so that the yarn is frictionally engaged by the shaft edge and, after looping around a shackle D, the yarn is withdrawn by rollers TR the peripheral speed of which is less than that of rollers FR. The yarn is backtwisted, or even reverse-twisted by 5-20% of its residual twist, between B and shackle D and its residual twist is restored thereafter. The shaft HS may have, attached to its yarn intake end, a propeller fan for producing air vortices, Fig. 4 (not shown) in which case yarn may be fed to the shaft axially thereof, i.e. loop formation is caused entirely by the vortices.
Patent GB-382321-A (GB)
Abstract: 382,321. Controlling motor vehicles. HAYES, F. A., Middletown, New Jersey, U.S.A. July 27, 1931, No. 21412. Convention date, Aug. 2, 1930. [Class 79 (v).] Automatic control means for motor vehicles comprises a centrifugal governor 22, Fig. 1, the hunting action of which is prevented by causing it to move a balanced valve 25 serving to direct pressure fluid to move a member 30 controlling the variable-speed gearing, not shown. There is also means for holding the control member 30 in the high-speed position notwithstanding subsequent reduction in the speed of the vehicle, and the maximum speed of the vehicle is not limited as it would be if the governor acted on the throttle. The gearing may be as described in Specification 254,341, [Class 79 (v), Motor vehicles &c., Steering &c.]. An auxiliary shaft 10 of the engine or transmission drives a pump 13 sucking oil up a pipe 15 and delivering it through a duct 16 to a cylinder space 35 between two valve pistons 17, 18 whence it normally escapes to the lubricating system through a pipe 19 with a relief valve. The valve 25 is keyed to revolve with the shaft 10 thereby minimizing frictional resistance to the governor 22, which acts against a spring 26 set as required. As the load eases or the vehicle accelerates from the low-speed position of Fig. 1, the valve 25 is pulled by the governor to the position of Fig. 2. Oil passes by a pipe 31 to a speed-control cylinder 29 and moves a piston 28 and speed-control rod 30 to the right, thereby increasing the speed of the vehicle until the increased load effects a balance on the engine. When the load falls sufficiently, the piston 28 moves far enough to uncover the end of a pipe 36 down which oil passes to a space 44 on the right of valve piston 18. The effect of this is to lock the control valve 25 and the governor resiliently in the high-speed position, preventing hunting. Further dashpot action may be obtained by constricting the pipe 36. An arrangement is described by which the automatic action may be overcome at the will of a driver comprising a push-rod under resilient manual control passing through the valve casing at 40, Fig. 2, and acting on the centre of the piston 18. The pipe 36 is dispensed with in a modification shown in Fig. 4. A small hole 43 is provided through the piston 18 by which oil pressure develops in the chamber 44 counteracting the governor spring 26. This chamber 44 communicates with a sump in the governor casing 33 past an adjustable needle valve 48.
