Title: Improvements in or relating to optical projection apparatus
IPC: H04N5/74
Filed: 1944-02-19
Abstract: 589,961. Optical-projection apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 19, 1944, No. 3122. Convention date, Feb. 19, 1943. [Class 97 (i)] In a system comprising a concave spherical mirror and a figured correcting plate the curvatures of a surface of the plate are exaggerated to overcorrect for spherical aberration and the surface is placed in contact with a readily deformable optical medium, such as a liquid, having a refractive index between that of the correcting plate and air so that the plate functions in the same manner as a lens having a figured surface of unexaggerated curvatures in contact with air. The effect of small variations of contour of the correcting plate due to errors in moulding or otherwise forming the plate is thereby reduced. As shown in Fig. 4, a concave mirror 54, mounted between flanges 57 of a liquid-tight casing 56 is separated by liquid 52, such as glycerin or a viscous colloidal suspension, from a correcting plate 53, having a figured surface 63 of exaggerated curvatures which is cemented to flanges 59 on the casing. The plate 53 may be formed as of synthetic resin by moulding or casting and has a refractive index greater than that of liquid 52. Passing centrally through this plate is a cathode ray tube 51, the face 55 of which emits light which, after refraction at the mirror 54, is refracted by the plate 53 on to an external screen 66. In another form the casing 56 is extended to the surface of the projection. screen which is translucent so that the liquid 52 extends from mirror to screen and the tube 51 and lens 53 are wholly immersed in it. In a further embodiment the external projection screen 66 of Fig. 4 is translucent and forms the outer face of a cell having an inner parallel transparent face and the cell enclosing a liquid so that the product of the dispersive power of the liquid in the cell and the width of the cell equals the product of the dispersive power of liquid 52 and the distance from the correcting plate 53 to the cell. Synthetic resins which may be used for the lens 53 are methyl methacrylate and polystyrene. Specifications 537,738, 559,065 and 560,150 are referred to.

A feed device for an automatic packing machine is of the type in which the articles to be packed are moved forward step by step, the articles being advanced in contact with one another along a first guide 1 on the entrance side and advanced regularly spaced apart along a second guide 2 on the exit side of the device, the guides being placed so that the one directly prolongs and forms a continuation of the other so that the articles to be packed pass from the first guide to the second without any change in the direction of their step-by-step movement. Figs. 1, 2. The articles are advanced step-bystep by driving member 5 along flat guides I until in turn they strike stop 15 and fall over step 3 in between projections 14<SP>1</SP> formed on lower guides 2 along which they are again advanced. During their movement along and between guides 1, the articles are conveyed on the flat right-hand portion of said driving member, the articles sliding backwards to the right at the end of the movement under the pressure from stop 15 because the stroke is greater than the article width, whereas during their movement along guides 2 they are conveyed between projections 16 formed on the left-hand portion of the driving member, each movement of the articles being equal to the stroke of the driving member. The driving member describes a rectangular path of which the upward movement is derived from driving rod 7 through parallel linkage 6, 8, 6<SP>1</SP> and the longitudinal movement is derived from driving rod 12 through parallel linkage 11, 6, 8, 6<SP>1</SP>; the connection between links 6 and 6<SP>1</SP> and said member 5 being by pin and slot 9, 10 and 9<SP>1</SP>, 10<SP>1</SP> respectively.

Title: Improvements in automatic steering apparatus of automobiles
IPC: B62D1/26
Filed: 1929-01-30
Abstract: 317,292. Takehara, T. Jan. 30, 1929. Automatic steering-control comprises a member adapted, when a steering road wheel drops into a rut, to engage the ground surface so as to be moved relatively to the vehicle, this movement being transmitted through linkage to the steering- gear and causing the steering wheels to be swivelled so as to steer them out of the rut. In the construction shown in Figs. 1 and 2 an arm 5, carrying a wheel and a projection at its lower end, is pivoted at 6 to the frame and is connected by a link 8 to one end of a bell-crank lever 9 the other end of which engages a slot in the track-rod 2. The arm 5 is normally held in a raised position by a spring 7, but when a road wheel drops into a rut the lower end of the arm engages the ground and the arm is moved, as the car moves forwardly, from the position shown in full lines to that shown in broken lines and the steering gear is actuated to steer the wheels out of the rut. The slot in the track rod allows the steering gear to be actuated in the usual manner without affecting the arm. In a modification instead of the arm 5 a cam is mounted on the vehicle; when a wheel drops into a rut the cam engages the ground and is caused to rotate, this rotation being used to actuate the steering-gear.
