Abstract: 1288503 Rotary shaft seals USM CORP 7 Jan 1970 [9 Jan 1969] 815/70 Heading F2B Sealing means for a rotor shaft 8 of a mixer comprises a sealing ring 11 pressed into sealing contact with the shaft 8 by an hydraulically actuated pivoted yoke 12. The yoke is pivoted on a stud 14 and has pins 13 at one end that engage the ring 11. One end of an hydraulic cylinder 21 is screwed into the other end 15 of the yoke and the piston rod 19 extands through the yoke and abuts a button 17 on a rod 18 loaded by a spring 16. The ring 11 is sealed to an end plate 7 and has a facing 10 which sealingly co-operates with a flange 9 on the shaft. When there is no hydraulic pressure in the cylinder 21, the spring 16 may be uncompressed and substantially no sealing pressure is applied by the pins 13 or, alternatively, the spring may exert a small sealing pressure by virtue of a pin and slot connection 15a, 18a between the piston rod 19 and the yoke. When hydraulic pressure is supplied to the cylinder 21 through a pipe 22 the spring 18 is partly or fully compressed and the required sealing pressure is applied by pins 13 to the ring 11. In the embodiment desired the mixer has two rotor shafts and sealing means according to the invention is applied to each end of the shafts, the pipes 22 for each of the four hydraulic cylinders being connected to a common supply line (22a, Fig. 4).

Abstract: 1296072 Measuring personal movements, electrically TELESTRATOR INDUSTRIES Inc 18 Nov 1969 [18 Nov 1968] 56251/69 Heading G1N [Also in Divisions G5 and H4] An audio-visual teaching system comprises a magnetic tape recorder controlling the display of still pictures projected from 54 on to the screen 52 of an electrostatic storage tube 51, the tube also being capable of displaying line drawings either stored as changing X and Y co-ordinates on magnetic tape as part of the teaching program, or generated by a conductive pencil 13 when moved over a conductive light-transmitting film 11 on the tube surface. The pencil 13 is used to generate the signals for storage when compiling the teaching program, which is thus able to draw markers or diagrams on the pictures projected from film strip 54, as well as provide an audio commentary. The signals for X and Y deflection of the beam, for erase and blackout, and for advance of the film strip, are modulated on subvideo frequencies on the magnetic tape. At certain points in the lesson the student may be required to answer a question by ticking a box projected on the screen, and the tape is then stopped after signals representing the area of the box for the correct answer have been read off. These signals are then compared with those generated by the pencil and if coincidence is detected the tape is re-started. If the wrong answer is given a second tape recorder may be started to give supplementary information prompting a correct answer and a return to the basic program. An alternative display device in which the stored X and Y co-ordinates control motors moving a stylus over a powder-covered glass plate is described. The X and Y voltages are generated by pickoff by the pencil of a voltage with A.C. and D.C. components from a tin oxide layer fed with D. C. along the X-axis and A. C. along the Y-axis, these components being separated to give the X and Y signals. Specification 1294340 is referred to.

When a temperature differential is applied across the body a current is induced in the turn. As shown, Fig. 1, the anisotropic element is formed as a circular helix, the material having major crystalline axes X1, X2 along which it has different thermo-emf coefficients, and pairs of heat sources 2 and heat sinks 3 are arranged round the element on diameters forming an angle of 45 degrees with the axes X1, X2. The heat sources and heat sinks are insulated from the element by a layer 5 and the centre of the element is filled with an insulator 4 having the same thermal conductivity as the element. The structure is said to be capable of producing outputs of the order of one hundred volts. In a second embodiment, Fig. 2 (not shown), the anisotropic element has the form of a helix each turn of which is of a rectangular shape having long and short sides inclined to the major crystalline axes of the material. The temperature difference is applied by a heat source and a heat sink arranged inside and outside the turns of the helix respectively. The positions of the source and sink may be reversed. In a modification, the size of each successive turn of the helix is decreased to form a conical structure which may be utilized to receive radiant energy on its inner surface to form a pyrometer. Equations relating the EMF produced to the dimensions of the element, its thermoelectric properties, the number of turns and the temperature difference are given.
