Title: Fluid control valves
Inventor: CRANG TERENCE FURSDON
IPC: F16K3/16
Filed: 1958-04-22
Abstract: 855,822. Valves. WHITE & CO. Ltd., J. S. April 14, 1959 [April 22, 1958], No. 12810/58. Class 135. A glandless valve controlling the flow of fluids in which even a small leakage is dangerous or undesirable, comprises a valve closure member movable in a valve chamber and a rotary hermetically sealed drive connected at its inner end to the valve closure member and passing through a valve chamber wall and a backing chamber in which is maintained a counterbalancing fluid pressure on the side of the hermetically sealed drive remote from the valve chamber. As shown in Fig. 1, a valve casing 10 formed with an extension 18 and housing a wedge-shaped gate 13 carried on a rotary screwed spindle 17 to control fluid flow between inlet and outlet ports 11, 12 is surmounted by a second casing 20 divided into upper and lower chambers 27, 26 by a flexible diaphragm 25. The diaphragm 25 clamped between upper and lower parts of the casing 20 is bonded to a driving pin 24 to seal the chamber .27 from the chamber 26. The pin 24 angularly disposed in bearing bushes on an extension of the spindle 17 and an extension of a coaxial operating spindle 21 passing sealingly out of the casing 20 through a rotary gland packing 28 constitutes a driving connection between the spindles; the pin on rotation of a hand wheel sweeping out a " double conical " path about a stationary mid-point on the common axis of the spindles. To reduce risk of rupture of the diaphragm 25, an auxiliary chamber 30 fitted on the side of the casing 20 houses a flexible bellows unit 31 whose interior communicates with the casing 10 and exterior with the chamber 27. The chamber 27 and auxiliary chamber 30 contain a cheap, innoxious fluid, e.g. oil or water, the pressure of which at least in part counterbalances the pressure of the controlled fluid. In the event of leakage from the chambers 27, 30 through the gland 28 or a gland 38 or increased pressure of the controlled fluid, the bellows unit 31 will expand to transfer oil or water from the chamber 30 to the chamber 27 to restore the pressure balance acting on the diaphragm 25. A piston head 32 on the bellows unit 31 carries a printer to indicate when the unit is fully expanded and a piston 41 may be screwed into a cylinder 40 to inject make-up oil or water into the chamber 30. A pressure gauge 43 communicating with the chamber 27 indicates whether the diaphragm 25 is ruptured or the bellows unit 31 is leaking or fractured.

Title: Improvements relating to methods of forming cement seals in oil wells
IPC: E21B33/134
Filed: 1953-05-11
Abstract: 721,101. Forming cement seals in oil wells. HALL, J. E. May 11, 1953, No. 13140/53. Class 85. To form a cement seal of predetermined length at a selected location in a well bore 10 there is mounted between stops on an open ended pipe 15 a number of abrading elements 18 which are rotated about and slidable along the pipe over a distance corresponding to the length of the seal. The pipe and the associated abrading elements are lowered into the bore to where the bottom of the seal is to be located, and the pipe is reciprocated to cause the abrading elements to clean both the bore wall and the exterior of the pipe whilst a fluid is pumped down the pipe to carry away, as it passes upwardly about the pipe, debris freed by the abrading elements. Then, whilst the pipe is still being reciprocated, the fluid is followed by cement slurry in an amount sufficient to form the required seal. After the slurry has been delivered to the selected location, a fluid is pumped downwardly about the pipe and withdrawn up through the pipe to clear it and the bore of any slurry not imposed upon the bore wall. Finally the pipe is withdrawn from the bore. When it is desired to form a solid plug in the bore, the pipe is raised after the cleaning and abrading operation until its end is just above the desired upper level of the plug. A back pressure valve 17 may be connected in the pipe 15 whilst it is being run into the bore, and removed after the introduction of the cement slurry to permit reverse circulation.

Title: Tempering of glass sheets
IPC: C03B27/04
Filed: 1963-04-03
Abstract: In the tempering of glass sheets by suddenly applying to the hot sheets a chilling fluid in a relatively cold atmosphere, the expected temperature of the glass is determined after a predetermined interval following the exposure to the cold atmosphere, the temperature of the treated glass is sensed and those sheets which have not been cooled to the requisite degree are rejected.  The sensing means operates a water spray to impinge on the over-hot sheets to fracture the sheets, the fragments falling into a pit below the conveyer, so that only the cooled sheets continue to an unloading station.  Specification 826,984 is referred to.

Title: Improvements relating to arrangements for determining distance by means of electromagnetic waves
IPC: G01S13/36
Filed: 1941-10-15
Abstract: 586,119. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and HOUGHTON, L. W. Oct. 15, 1941, No. 13279. [Class 40 (v)] In order to determine the distance of an object 'by the reflection of electromagnetic waves, the frequency of the transmitted wave is adjusted until a specified phase change occurs between the transmitted and received waves, the adjustment being effected automatically by means controlled by the phase difference between the directly received wave and the wave after reflection. The frequency of an adjustable frequency oscillator 1, Fig. 4, is indicated as a voltage by a frequency discriminator circuit 2 and indicator I. An arbitrary frequency from this oscillator is modulated in a balanced modulator 4 by a frequency from a constant-frequency oscillator 3. The resulting side bands are separated by filters 5, 6, the outputs being applied to modulate a transmitter T. After reflection at the object the waves are received on a collector antenna RA and fed to a receiver R. The two frequencies received are separated by filters 7, 8 and then passed to modulator units 9, 10. The outputs from these are added to the energies of their corresponding frequencies from the outputs of the filters 5, 6. The outputs from the modulators 9, 10 are rectified in rectifiers R1, R2 and applied to a differentiating circuit 11 to obtain a differential output which is applied to vary the frequency of the oscillator 1 until the outputs from the modulators 9, 10 are equal, the phase change between the transmitted and received waves then being 180 degrees. The frequency indicated on the instrument I is a measure of the required distance. In a modification, the indicating means comprises a cathode-ray oscillograph to one deflecting unit of which is applied the sum or difference frequency and to the other deflecting unit of which is applied the vectorial sum of the transmitted and received energies of the corresponding sum or difference frequency.

It is stated that the high extrusion pressure eliminates the need to draw the conductor 31 through the die head, from the die whereof the covering is cooled by passage through an unpressurized cooling device and coiled under zero tension. In the Fig. 2 embodiment (not printed) the insulating layer is applied directly to the conductor, but in the Fig. 3 embodiment the insulating layer is applied over a cross-linkable semi-conducting smoothing layer 33, e.g. of ethylene polymer filled with carbon black, which is applied to the conductor 31 in the same head and simultaneously cross-linked during passage through the die 20<SP>1</SP>. In the Fig. 4 embodiment (not printed) the semi-conducting and insulating layers are applied by passage through consecutive heads, in either the former or the latter whereof the cross-linking of the semi-conducting layer is completed. The extrusion surfaces of the head are covered with an adhesion preventing covering. The pressure effect of the elongated die 201 may be enhanced by the passage thereof tapering towards the outlet. The cross-linking prior to extrusion from the die and the high pressure therein prevents the formation of voids or bubbles in the insulation.
