Title: Improvements in or relating to the Measurement of the Shape and Flatness of Sheet or Strip Material
Inventor: PEARSON WILLIAM KENNETH JAMIES
IPC: B21B38/02
Filed: 1965-07-09
Abstract: 1,160,112. Straightening; rolling. BRITISH ALUMINIUM CO. Ltd. 7 July, 1966 [9 July, 1965], No. 29224/65. Headings B3E and B3M. [Also in Divisions F2, G1 and G3] The surface flatness of sheet or strip material particularly that emerging from a rolling mill, is measured (and may be automatically controlled) by moving the strip relative to at least two rollers which are pressed against it by fluid pressure so as to reduce tension inequalities in and locally deflect the strip, and deriving a measure of the fluid pressure. In one embodiment, a stationary shaft 50 below the strip carries a number of rollers 10 mounted on air or liquidpressure bearings side-by-side across the width of the strip. Each roller 10 has six equi-spaced sets of jets round its inner periphery, each set of jets comprising two supply jets 53 and a pressure measuring jet 54. The displacement of each roller as it follows the strip contour is measured by the pressure difference across the bearing detected by a transducer (of unspecified type) which measures fluid pressure electrically. In a modification, Fig. 4 (not shown), the pressures applied to the two halves of the bearing are automatically controlled to re-centralize the bearing, and the change in pressure to effect this is measured electrically. Instead of measuring the pressures across the bearing, the bearing clearances may be measured by capacitative transducers, Fig.s 6 and 7 (not shown). The electrical outputs from the transducers across the strip are scanned sequentially, Figs. 8 and 9 (not shown), and their instantaneous outputs are compared with the average of the preceding scan to provide an indication of the profile of the strip and also to control (in an undisclosed manner) roll force, roll bending, strip tension and oil coolant flow in such sense as to improve the profile of the strip.

Title: Improvements in conveying devices, more particularly for glass annealing furnaces
IPC: C03B25/06
Filed: 1936-10-29
Abstract: 461,553. Step - by step conveyers. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT BEHEER EN EXPLOITATIE VAN OCTROOIEN. Oct. 29, 1936, No. 29440. Convention date, Nov. 1, 1935. [Class 78 (i)] In a conveyer, particularly for passing glass articles through an annealing furnace, wherein a series of moving longitudinal bars alternate with a series of stationary bars, the path wherein the moving bars travel is arranged so that its rising and descending portions are not parallel to one another and the level of the stationary bars is made adjustable whereby the lengths of the moving paths cut thereby may be varied so as to alter the dwell and moving periods of the articles and so vary their rate of progress through the furnace. In the example shown in Fig. 3, each point on the movable bars traverses a circle C clockwise, whereby, with the stationary bars B at the level indicated, an article G is conveyed from P to P<1> through a horizontal distance w and rests on the stationary bars for the time taken by the movable bars to complete their movment from P<1> to P. By raising the bars B to the position B<1>, Fig. 3a, the distance w<1> advanced by the articles for each movement of the movable bars is decreased and the time of the dwell period P<1> to P is increased. In other examples the paths of the points of the movable bars may be in the form of triangles. To provide for the passage of articles requiring different lengths of treatment the conveyer may be divided longitudinally into portions having the stationary bars of one portion set higher or lower than those of another portion. In another form the conveyer may be divided laterally into portions wherein the stationary bars in one portion are at a different level to those in another portion, those in an intermediate portion being inclined so as to permit the uninterrupted passage of the articles from one portion to another at a progressively increasing or decreasing rate. Alternatively, the conveyer may be divided both longitudinally and transversely into portions. The heights of the stationary bars may be adjusted by any ordinary means and the motion of the movable bars may be derived from cranks and connecting rods.

Title: Improvements in or relating to piezo-electric crystals
IPC: H03H9/19
Filed: 1936-11-02
Abstract: 474,701. Piezo -electric crystals. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 2, 1936, No. 29770. Convention date, Oct. 31, 1935. [Class 40 (v)] A crystal is so cut as to be capable of vibrating at two predetermined fundamental frequencies in the direction of its thickness. A section 3, 5, Fig. 3, normal to the optic axis Z is first cut from the mother crystal and a portion 5, Fig. 4, is taken from this. Sections 9, 7 having their thicknesses perpendicular to a mechanical or crystallographic axis Y and an electric axis X, respectively, have two different natural frequencies for vibrations in planes parallel to their thicknesses, but an intermediate section 11 exhibits two natural frequencies simultaneously. The ratio of the latter two frequencies bears a linear relation, Fig. 1 (not shown), to the angle between the faces m, n and the plane normal to the axis X. Plates 11 whose faces m, n are inclined at less than 1‹ to the planes normal to the axes X and Y respectively will not vibrate satisfactorily. Plates 11 whose faces are inclined at an angle of cut lying between 8¢‹ to 29‹ to the plane normal to the axis X can be used for generating oscillations at both frequencies, but plates 11 for which this angle is less than 8¢‹ will oscillate only if they are driven. The invention consists in (1) choosing the angle of cut by the aid of the graph in Fig. 1 (not shown) so that the two frequencies shall bear a predetermined ratio to one another, and (2) choosing the thickness of the crystal, by the aid of the graph in Fig. 2 (not shown), so that one of the frequencies may have a predetermined value. The value of the other frequency then conforms.

Abstract: 339,709. Bull, J. A. Oct. 3, 1929. Torpedoes, locomotive ; launching.-A torpedo to be dropped from an aircraft is provided at its tail with a resistance body which checks the speed of the torpedo on entering water and then becomes disconnected, the engine of the torpedo being started after the speed of the torpedo has been reduced. The resistance body may be a cylinder M with screw ribs V and a screw stem S screwing into a nut K on an arm B hinged to the tail of the torpedo T on a pin C. When the torpedo enters the water, the speed is reduced by the resistance of the body M which is rotated by the action of the water on the ribs V. After a given time, the stem S becomes detached from the nut K, and acting on a ring R pulls the engine starting lever J through a line L. In a modification, the stem S of the resistance body screws into the tail end of the inner hollow propeller shaft, and a universal joint is provided in the stem. The stem is unscrewed by the rotation of the propeller shafts caused by the flow of water past the propellers.

In apparatus regulating the outlet temperature of medium flowing through a heat exchanger, an element influencing the medium entry temperature is controlled by a regulator responsive to outlet temperature and having at least an integral characteristic, the element receiving a preliminary impulse from a regulator responsive to the medium temperature intermediate entry and outlet but without an integral characteristic. Working fluid passes an injector 7 to a heat-exchanger, i.e. superheater 1, the temperature at the inlet, at an intermediate point and at the outlet being detected at 17, 21 and 19 to transmit negative pressure signals above piston 25 and positive below piston valve 28 and below piston 25, respectively, to move valve 28, servo-piston 11 and valve 9 controlling the supply of working fluid at 8 to injector 7 to regulate the outlet temperature, the signal from 19 having a proportional-integral effect by acting on the end of manually set piston valve 31 controlling pressure across piston 29 via restrictions 35 and also across spring-centred piston 38. The signal from 21 may provide a proportionalderivative effect. Flow, detected at 10 in line 8 or upstream of injector 7 sends a pressure signal to the upper end of piston valve 28 for maintaining a constant flow. The intermediate part of the superheater for detector 21 is protected from the furnace. The regulation may be effected electrically.
