Abstract: 1, 054, 082. Turn-sensitive devices. CSF. - COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 13, 1964 [April 19, 1963], No. 15275/64. Heading G1C. A turn-sensitive device for measuring the velocity of rotation of a platform 4 about a predetermined axis comprises a support 12, an elongated member 10 carrying further members 20, 30 symmetrically positioned in Fig. 2 (not shown), coils 30, 31 for causing vibration in members 20, 30 and means for measuring the torsional vibrations of the elongated member. The rod 10 is supported by a ring 11 and has at one end a metal tongue 14 movable between coils 15, 16 carried by a bracket 17 connected to the support 4. In operation, as the platform 4 rotates about the OX axis with angular velocity W couples V 21 -V 22  and V 31 -V 32  are applied to prongs 20 and 30 to cause them to vibrate, and simultaneously torsional couples V 23 -V 24  and V 33 -V 34  are applied to the prongs. This results in a torsion of rod 10 at the vibration frequency of the prongs the amplitude of the vibration being proportional to W and is determined by the coils 15, 16.

Movements of the piston 16 of a tube-withina-tube type hydraulic shock absorber are only lightly damped when the piston is oscillating about a minimum load position I, but are more heavily damped when the piston is oscillating about a loaded position, e.g. II. When the piston is in position II, the valves in the piston alone effect the damping, but when the piston is in position I a fluid by-pass groove 60 in the inner tube 10 modifies the damping. The groove may be replaced by a pair of axially spaced ports (not shown) in the inner tube, thus providing a fluid by-pass from one side of the piston to the other through conduits in the reservoir 14. Alternatively, the inner tube may have a portion of increased diameter.

Abstract: 1,239,094. Continuous strip-heating furnaces. MICHIGAN OVEN CO. 30 June, 1969, No. 33033/69. Headings F4B and F4G. An oven in which a vertical heated chamber has upper and lower openings which allow the passage of strip material therethrough, has a pressure seal system including a blower which maintains a pressure drop across the upper opening sufficient to inhibit gas flow therethrough and a thermal sensor therein to vary the speed of the blower via a control means in response to temperature changes to prevent gas entering or leaving the chamber. In an oven 10 for drying and curing a coating on a continuous foil 17, Fig. 1, the upper opening 19 of the heated chamber 21 is surrounded by a pressure-box 41 into which air from a blower 43 is introduced. The chamber 21 is heated by air from a blower 24 passing over a burner 26, the air passes up the chamber 21 and is exhausted through ducts 32. The thermo-couple or mercury expansion element 48 senses the temperature in the upper opening 19 and is linked to a control circuit 49 which increases the speed of the blower 43 if the temperature rises and vice versa. The control system is designed to allow substantial variation from the normal working temperature before adjustment of the speed is made in order to ignore short-term thermal effects. In a second embodiment, Fig. 3, the pressure seal comprises a Venturi nozzle 152 which produces a lowpressure point in the upper opening 119. Air is drawn into the lower half 101 of the oven 100 by a heater fan 124 and is directed on to the surface of an insulation coated wire 117. The hot air passes up the vertical chamber 121 into the upper half 102. Radiant heater panels 130 also serve to aid the drying of the insulating coating. In the upper half 102 the air is circulated by blower 148 over two sets of catalytic combustion elements 143, 144 and through a Venturi nozzle 152. The air then comes into contact with the wire 117 again before being mixed with the air coming up from the lower half 101 and then recirculated. A thermal sensor 161, control circuit 162 and variable-speed drive 163 control the speed of the blower 148 as before.

Deflection of the light beam may occur by way of normal Bragg diffraction, in which the polarization of the incident and deflected light is identical, or via abnormal Bragg diffraction, which occurs for birefringent materials and in which the polarization of the deflected light is changed (see IEEE, J. Quantum Mechanics, QE-3, 1967, page 88), measurements of figures of merit M and M<SP>1</SP> are given for different acoustic and optical directions. L-mode acoustic waves have a relatively large velocity and therefore are useful for a rapid deflection system, whereas the S-mode wave in the [110] direction has a greater value of M and thus of deflection efficiency with a much reduced velocity. The S-wave in particular directions e.g. [1À38, 1, 0] has a zero temperature coefficient of velocity so that temperature variations do not affect the deflection angle. For two dimensional deflections, two deflectors may be arranged in tandem with mutually orthogonal acoustic propagation directions, or two transducers may be disposed on the same crystal to supply orthogonal waves thereto. In the former case a half wave plate may need to be inserted between the two devices. The use of differing types of acoustic absorbing materials is discussed, chalcogenide glasses such as arsenic selenide and sulphide being formed.
