Abstract: 288,851. Zaidan Hojin Rikagaku Kenkyujo, Okochi, M., and Ebihara, K. June 8, 1927. Dynamometers. -. Relates to apparatus for measuring piston ring pressures upon the cylinder wall by means of a piezo-electric effect as described in Specification 280,295 and comprises a particular construction for testing rings of different diameters. The mother body 1 provided with a shallow cylindrical cup 2 is fixed to a foundation. A cylinder 3 for receiving the ring to be tested is flanged to fit the cup 2 and is arranged coaxial with the axis x-x<1> of the mother body. The rod 4 of the piston 17 is guided along the axis of the body 1. The guide cylinder 6 for the piezo pressure device is clamped to an arm 5 on the body 1. A piece 10 made of the same material as the cylinder and projecting through the cylinder wall is curved on the inner surface to a radius equal to that of the largest ring to be tested. The outer surface of the piece 10 engages the inner of two or more quartz blocks the outer of which engages an abutment 13 in a cylindrical block 13<1> which may be adjusted in the cylinder 6 by a screw 14. In use, a standard cylinder, carefully bored to the same diameter as that for which the ring is intended, is secured in the cup 2. A standard ring is then secured between the plates 19, 20 of the piston and the quartz blocks and piece 10 advanced by the screw 14 until the piece 10 touches the ring. The block 13<1> is then clamped. The ring to be tested is next substituted for the standard, and any deflection in the reading of the electrometer indicating the piezo electric charge noted. The piston is then raised to the top of the cylinder and turned through an angle together with a graduated ring 21 located in a recess at the top of the cylinder and the test repeated. This is done until the whole circumference of the ring has been covered. The pressure device may be calibrated by known pressure given by weights acting through a pivoted two-armed lever 22.

Title: Improvements relating to the stereoscopic presentation of pictures
Filed: 1943-09-20
Abstract: 571,061. Projecting stereoscopic images. MATTHEWS, F. W. M. Sept. 20, 1943, No. 15422. [Class 97 (i)] [Also in Group XL] Apparatus for projecting stereoscopic images comprises a projector with means for dividing the right and left eye images into narrow vertical strips and a shutter which renders visible in succession single pairs of these strips, each pair being formed of one right eye and one left eye image strip, together with a projection screen having a waved surface formed of narrow vertical elements inclined alternately in opposite directions to the general plane of the screen, the right and left eye image strips being projected on to screen elements facing respectively to the right and left of the spectator ; whereby, it is stated, each eye has a greater appreciation of the picture elements appropriate to it than of the others, so producing a stereoscopic effect. In the projector shown diagrammatically in Fig. 1 a line screen 5 mounted in the film gate divides the left and right eye images L, R on the film 4 into strip elements, and a shutter 3 is provided with slots 11, 12 which uncover a single pair of elements, one from each image, at a time. The shutter is reciprocated one or more times during the projection of the pair of images so that all the strip elements are projected in pairs in succession on to a screen of the zig-zag form in horizontal section shown in Fig. 8, with or without baffle strips 33. The right-eye strips are projected in succession on the portions A, C, E and the corresponding left-eye strips are similarly projected on the portions B, D, the projection of each pair of strips ceasing before that of the next pair commences owing to the passage of the slots 11, 12 in the shutter over the lines of the screen 5. An adjustable prism system 7, 8, 9, 10 in front of the objective 6 is provided for projecting the right and left eye strips from laterally-spaced points. A television system is referred to in which the right and left eye images are formed on the screen of a television camera in front of which is a line screen corresponding to the screen 5. The two images are simultaneously vertically scanned by two cathode rays spaced apart to correspond with the slots 11, 12 in the shutter 3. The strip image elements of each pair as they are scanned are reconstituted separately on the image screens of two corresponding projection cathode ray tubes and their images are separately projected on to a screen of the same form as that shown in Fig. S.

Title: Improvements relating to the production of flexible films, filaments and the like
IPC: D01F9/00
Filed: 1942-11-12
Abstract: Coherent, self-supporting films, filaments and coatings made from colloidal dispersions of inorganic silicates or hydrous oxides such as bentonite or vanadium pentoxide as described in Specification 535,850, are given improved electrical properties and water-resistance by treating with a solution of a salt, the cation of which has an ionic diameter at least equal to that of divalent lead and the anion of which is an anion of an organic acid capable of polymerization, and subjecting the treated film &c. to further treatment to bring about polymerization to form a hydrophobic product insoluble in water.  Suitable cations for the treating salt are the divalent cations of lead and barium and the monovalent cations of potassium, rubidium, caesium, thallium, gold, ammonium, ethylamine, ethylene diamine, or diethylene triamine.  Suitable anions are those of polymerizable olefinic carboxylic acids such as acrylic, methyl acrylic, vinyl acetic, or vinyl acrylic acid.  The film &c. is treated with a saturated or nearly saturated solution of the salt at a temperature of about 70 DEG  C. and dried.  Polymerization occurs on storing, but is accelerated by heating, e.g. up to 175 DEG  C. The treatment of bentonite films with aqueous solutions of lead acrylate, lead methacrylate, barium acrylate and diethylene triamine acrylate, is described.  Barium acrylate is made by dissolving barium carbonate in a concentrated aqueous solution of monomeric acrylic acid and crystallised by evaporation.  Diethylene triamine acrylate is made by adding aqueous acrylic acid to aqueous diethylene triamine until neutral, the temperature being kept below 70 DEG  C. by adding the acid slowly.  The solution is filtered after adding carbon black. Specification 573,759, [Group VIII], also is referred to.

Patent GB-449716-A (GB)
Title: Improvements in and relating to animated display devices
IPC: G09F11/23
Filed: 1935-06-06
Abstract: 449,716. Moving signs. AIRD, H., 1326, Burrard Street, Vancouver, Canada. June 6, 1935, No. 16511. [Class 3 (i)] A display device shows the apparent lighting of a cigarette, its intermittent glowing during smoking, the gradual shortening of the cigarette, and light effects simulating spirals of smoke rising from both ends of the cigarette. The device is bounded bv a cabinet 1 the front of which comprises a translucent screen 6 having a transparent window 7 and bearing a painted representation of a face the lips of which are disposed at one end of the window. The cigarette 33 is carried by a frame 31 actuated by a rack 23 to reciprocate the cigarette. At the end of its outward movement a lamp 59 is lit and when it reaches this lamp a glow lamp 34 in the cigarette end is illuminated together with a lamp 60. The cigarette is then slowly withdrawn, a spring contact 40 moving over a rack switch 41 to give intermittent glow to the lamps 34 and 60. The effect of rising smoke is produced by the shadows of two wire spirals 49, 50 rotated between the lamp 60 and the screen 6. The spirals may be covered with fluffed cotton batting and a second shaded or coloured diffusing screen may be introduced between the wires 49, 50 and the screen 6 to improve the effect. The wire 50, representing smoke issuing from the mouth of the figure, is carried by a sheave 47 carried by a fixed standard 48, while the wire 49 is carried by a sheave 38 mounted on the cigarette-carrying frame to travel to and fro with the cigarette. The sheaves 38, 47 are rotated by an endless belt 45 passing also round a stationary sheave 44 on a motor driven shaft 12 and a sheave 46 carried by a spring- retracted arm to tension the belt. The rack 23 is moved toward the face 8 by a pinion 22 driven by a wheel 17 from the motor 15 through a clutch 20, and is returned rapidly outward by a spring 28 pulling a cord 27 wound round a pulley 25 connected to a pinion 26 gearing with the rack, when the clutch 20 is released. The release of the clutch 20 is effected by a ramp 51 bearing against a fork lever 21, and is held in this open position during outward movement of the cigarette by the attraction of an electromagnet 58 for an armature 57 carried by the lever 21. A switch 55 actuated by abutments 53, 54 on the frame 31 controls the magnet 58. The lamp 59 is momentarily lit by a contact switch 63 when the frame 31 reaches its outermost position, and the rapidity of the outward motion prevents the rack switch 41 from effectively lighting the lamp 34 during said movement.
