Abstract: 793,170. Electric analogue calculating systems. GENERAL ELECTRIC CO., Ltd., and KIRKNESS, R. H. July 29, 1953 [July 24, 1952], No. 18823/52. Drawings to Specification. Class 37. Voltages corresponding to the co-ordinates of a point in a first set of Cartesian co-ordinates are applied to a thermionic circuit from which are derived voltages corresponding to the coordinates of the point with respect to a second set of Cartesian co-ordinates rotated an angle # from the first. In the Figure, not shown, A.C. voltages proportional to the X and Y co-ordinates of the first Cartesian system are supplied to separate balanced modulators each of which are supplied with a second A.C. voltage from an oscillator of frequency f, the two latter voltages being in quadrature. The modulated outputs are proportional to X sin 2# feet and # cos 2# feet respectively and are added and passed through a filter to attenuate frequencies above f, the resultant signal being proportional to (X sin 2# feet + # cos 2# feet). The latter is applied to two gating devices operated from a pulse generator, the phase of the output of which is a function of #. The output of the gating devices may be passed through low-pass filters to provide D.C. voltages representing the new co-ordinates.

Title: Improvements in or relating to apparatus for indicating leakages in the tubes of heat exchanger systems
Inventor: HAYWARD MICHAEL STANLEY
IPC: G01M3/00
Filed: 1959-06-02
Abstract: 874,626. Indicating leakages in tubes. SIMON-CARVES Ltd., and GENERAL ELECTRIC CO. Ltd. June 2, 1960 [June 2, 1959], No. 18824/59. Class 99(2). In a method of indicating leakages in a heat exchanger system which is leaking and which is of the kind having a bank of tubes 2 arranged to be surrounded by a heat transfer fluid and communicating with a tubular header 1 at the each end of the system a purge gas is introduced into any of the tubes of the system and the gas emerging from the tube is sampled whereby the presence in the emerging purge gas of any of the fluid surrounding the tubes of the system provides an indication of a leak in the tube. As shown in Fig. 1, a traversing probe 3 consisting of a central rod 4, on which is mounted a pneumatically operated piston-and-cylinder device 5, Fig. 2, and two cruciform spiders 6 adapted to support the rod 4 on the axis of the header, introduces the purge gas into a tube 2. The portion 7 of the rod 4 is drilled to receive the cylinder 8 of the device 5 which is adjustably positioned by a bracket 9. A spring-loaded piston 15, to which is attached a rubber nozzle 16, is movable in the cylinder 8 by means of compressed air from supply pipe 12. The nozzle 16 incorporates a small bore tube 18 connected by a pipe 19 to a supply of purging gas. The spiders 6 comprise legs 20, screwed into collars 21 rigid with rod 4, on which are attached spring-biased feet 22. By adjusting the bracket 9 and interchanging the legs 20 the probe 3 can be adapted for varying diameters of headers. The probe 3 is movable axially and angularly and is positioned in these respects by a grub screw (not shown), and a screw 27 in one of the circumferentially arranged holes 28. The probe 3 is therefore moved to a position so that the nozzle 16 is in alignment with a particular tube 2 and, after the nozzle 16 has been urged into the end of the tube by compressed-air, purge gas is introduced into the tube. A second similar traversing probe with a different nozzle 30, Fig. 4, is fitted into the header of the heat exchanger remote from header 1 to sample the gas emerging from the tube 2 under test. The tube 31 is connected to an infra-red continuous gas analyser and the drillings 32 ensure a small positive pressure inside the tube 2 under test besides eliminating any " in-leakage " of air around the nozzle 16. Several tubes 2 may be tested simultaneously by providing several piston and cylinder devices 5 on one probe. According to the Provisional Specification the apparatus may be used with a heat exchanger which is not pressurised externally. The inside of the tubes 2 and one of the headers are evacuated and the increase in flow into the evacuated header when pumping from a leaking tube 2 is noted, the other end of the tubes 2 being blocked off.

[Also in Division A3] A method of shaping a shoe upper 1 includes the steps of locating the upper up to its feather edge 2A in a female mould 6, closing the mould 6 by a closure plate 13 which, with the mouth of the mould 6, conforms to the contour of the feather edge 2A and forming the upper to the shape of the mould 6 by the expansion of an elastic bag 5 arranged within the upper 1 in the mould 6. The closure plate 13 and bag 5 are mounted on a stem which can move heightwise to allow loading and unloading of the upper and the stem may include inlet means for supplying pressure fluid to the bag 5. The pressure fluid and/or the mould 6 may be heated. The upper 1 may be moistened before moulding and the mould 6 may be permeable to allow moisture to escape when the upper 1 is heated. The upper 1 may be positioned in the mould 6 and/or over the closure plate 13 by means of pins 22 (Fig. 10) passing through holes 3 in the margin 2 of the upper 1, the pins 22 also preventing the margin 2 from being drawn into the mould 6 when the bag 5 is expanded. Alternatively, the upper may be positioned by clips, straps or projections on the upper 1. The method can be applied to uppers of various styles, e.g. conventional styles, sling back shoes and sandals, and various upper materials, e.g. leather, P.V.C., imitation leather and plastics coated fabrics. After shaping the upper 1 and removal of the pins 22, a sole mould 10 may be placed over the mould 6 and a sole moulded on to the upper, e.g. by injection of material through duct 12. The sole is bonded to the margin 2, the bonding being improved by the holes 3 in the margin 2. Suitable materials for the sole are polyurethanes, natural and synthetic rubbers, and other plastics materials, such as P.V.C. and polybutadiene. The sole may be moulded by injection or vulcanization or alternatively a pre-formed sole may be adhered to the margin 2.

These gaps may be short-circuited when not required by transverse conductors 25 carried in a bar slidable in the casing. Individual plugs may be short-circuited by depressing one of a series of plungers 9, the reduced inner portions 8 of which put the distributor leads 3 into connection with the plate 6 and earthed wire 4. The stems 8 pass through openings 31 in a second slidable bar 27 which also has transverse connectors 28, 29, 30 so that by sliding the bar 27 all the distributing leads are connected to the plate 6 and earth lead 4. In this position the bar may be locked, a key being provided for releasing the bolt 33 from the slot 36. In one arrangement a pattern of key is employed which may be removed only when the bar is locked in the short-circuiting position. More effective operation is obtained by providing ventilating openings and spaces 60, 56, 55 and 59. the opening 60 being sufficiently elongated to permit the insertion of a wiper for the windows of the casing. Surface leakage over the insulation between the conductors 28 and plungers 8 is avoided by leaving a clearance above the bar 27. Disconnection of the primary circuit in the inner locked position of the bar 27 may be caused by arrangement that a conducting piece on the bar shall break contact with one of a pair of contacts, the conducting piece and contact forming part of the primary circuit.
