Abstract: 621,028. Weighing-apparatus fitted to mixing-machines. BLAW KNOX, Ltd., WILSON, S., and WHEELER, F. C. July 5, 1945. [Class 143] A transportable mixing machine such as a concrete or macadam mixer wherein a skip is adapted to be swung up from a weighing position into a position to discharge its contents into the mixer is provided with a frame to support the skip and the weighing mechanism which transfers the weight of the skip and its contents to a weight indicator, said frame being supported on the ground during the weighing and discharging operations, and being pivoted to the machine and having combined with it means carried by the machine for swinging it up and down relatively to the machine so that in the raised position the frame with the skip and said weighing mechanism is folded close alongside the machine above the ground ready for transport. A pair of trapezoidal frames 4 span the main frame of the mixer and are joined by a shaft 5 carrying drums 6 for a cable 7 attached to a skip 12 mounted in the weighing apparatus frame comprising side tubes 8 pivoted at 9. and bridged by a member 10 having feet 11 for resting on the ground. By rotation of shaft 5, the frame can be folded from the operative position shown into a substantially vertical position against the mixing barrel 3. The weighing apparatus is of known form comprising links and levers 13, 14, the latter supporting the pouring end of the skip which has an abutment thereon. The front part of the skip is pivoted to allow oscillation into and away from the pouring position by fitting it with notched plates 18 which oscillate upon a cross rod fixed to the frame 8, 10. These plates move out of engagement when the skip is in the weighing position but on tilting the skip to discharge it or raise it to the folded position, the weight of the skip is taken by said cross rod. The weight indicator 17 is flexibly connected to the output lever 24 by a cable 22. When the skip is to be raised to the folded away position, it is braced upwardly by operation of a strut 28 having cranked ends pivoted at 29 to the members 13, which engages its base. A clamping bar 30 is secured across studs 32, and a spring clip carried by the adjacent member 8 is sprung over lever 24.

Title: Improvements in stereoscopic photography using a kinematograph camera
IPC: G03B35/00
Filed: 1947-07-03
Abstract: 631,410. Stereoscopic kinematography. WOOD, F. July 3, 1947, No. 17592. [Class 97 (i)] When photographing an object or scene with a kinematograph camera, the camera lens and either the camera body with the film gate therein or the film gate itself are moved slowly in front of the object or scene in parallel rectilinear paths in such a manner that the rate of travel of the lens is slightly less than that of the camera body or film gate, while the camera body or film gate are moved over a distance slightly greater than the average interocular distance through which the lens is moved so that decentring of the recorded images is avoided and a. stereoscopic effect is ensured when the recorded images are projected. In an apparatus for carrying out this method, the lens 2 of a kinematograph camera 1 is mounted for sliding movement in guides 4 on the camera front and the camera is mounted on a base 5, which is slidable along rails 6 on a fixed platform 8. The camera 1 is connected by a rod 15 to a crank-lever 9, which passes through an elongated slot at 17 in the rod and through a similar slot 23 in a rod 21 connected at 22 to the lens mount. Rotation of the crank 9 by an electric motor 13 and reduction gearing 14 thus causes reciprocating movements of the camera 1 and of the lens 2 thereof and the crank-lever is so designed that the lens moves through the average interocular distance, while the camera 1 moves over a slightly greater distance and at a slightly higher speed. The camera itself may be stationary, the rod 15 being connected to the film gate only. The positive film obtained after focusing the film used in the camera may be fed through the usual kinematograph projector or may be scanned by any television scanner for translation of the images into, and transmission of, television signals for reception and conversion into stereoscopic images on the screen of a television receiver.

Filed: 1917-11-28
Abstract: 122,667. Mansell, J. H., Carpmael, R. H., and Sotham, J. C. Nov. 28,1917. Disk, wheel, and roller apparatus; gauges. - In a device for gauging work being operated on by a tool, abrading-wheel, &c., the movements of the gauge are magnified by hydrostatic means, and are either indicated by an audible signal, dial, or coloured light, or caused to correct the position of the tool. In a lathe, the frame 6 supported by a pillar 4 from the saddle 1 carries a wheel 7 pressed up against the work 9 by an adjustable spring 5 and also a spindle 12 with a wheel 12 pressed down by a spring 17, Fig. 4. Movements of the spindle 12 relative to the frame force oil from either end of the cylinder 16 into the open end of either of the U- tubes 26, Fig. 6, containing mercury, which is thereby caused to make contact with one of the terminals 28. The electric current started thereby may drive a reversing motion in the direction required to correct the position of the tool automatically; or the current may pass through one of the solenoids 29, 30, Fig. 8, which withdraw a stop 33 allowing a weight 35 to fall and, by means of a pawl 45 and ratchet 38, rotate the tool-feeding screw in the desired direction. The weight is returned by hand. The position of the wheel 8 is adjusted, for different sizes of work, by a nut 13 having external graduations, and, for taper work, this nut may be automatically rotated during the traverse of the saddle. For this purpose, a spindle 46, Fig. 10, on the saddle has pinions engaging a fixed rack 45 and a gear 49, this having a pinion in constant engagement, with a gear 54 on an arm 55, which can be moved, by a lever 61 resting on stepped plates 62, so as to engage one of the speed gears 56, 57, 58, 59. These are on a spindle having a gear 60, which engages the teeth 18 on the nut 13. When great accuracy is not required, the roller 7 may be omitted.
