Title: Apparatus for responding to radio interrogation signals
IPC: G01S13/78
Filed: 1945-03-05
Abstract: 588,777. Wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. March 5, 1945, No. 5513. Convention date, Oct. 26, 1943. [Class 40 (v)] A system for emitting a characteristic signal in response to an interrogating signal is arranged so that a power supply is connected to the transmitting portion of the set through a relay actuated by the interrogating signal. Fig. 1 shows an arrangement which is responsive to an interrogating signal 30 comprising two pulses 31, 32 separated by a given time interval t1. The output of the detector, which is fed by aerial 10, is applied to one grid 36 and through a delay device 34 to a second grid 37 of a gating valve 38. Unit 34 causes a delay t1, equal to the interval between pulses 31, 32, thus the interrogating signal 30 triggers the valve 38, which produces a pulse 43. This pulse 43 is applied to the grid of a gas-filled valve 54 and to signal generator 22. The signal generator 22, however, is not triggered by the pulse 43 until it is connected to the power supply unit 25 through relay contacts 50, 51. The winding 62 of the relay is connected in the anode circuit of valve 54, which strikes when pulse 43 is applied to its grid, causing contacts 50, 51 to close and connect the power supply unit 25 to the signal generator 22 and the oscillator 23. The relay 62 is preferably of the slow-release type, so that contacts 50, 51 remain closed as long as interrogating signals 30 are being received. After a heating period, signal generator 22 produces pulses characteristic of the particular station in answer to each received signal. The output of the signal generator 22 modulates the oscillator 23, producing reply signals for radiation from aerial 10. The output of oscillator 23 is preferably different in frequency or form from the interrogating signals. The signal generator 22 may be of the " flip-flop " type producing a square pulse, or of one of the forms described in Specification 601, 536 as open to inspection under Sect. 91. Instead of using a slow-release relay, the gas-filled valve 54 may be arranged to fire for a period longer than the interval between interrogating signals.

Title: Temperature of a moving man-made filament yarn
IPC: D01D10/04
Filed: 1974-02-07
Abstract: 1419473 Heating and cooling yarns ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 7 Feb 1974 [9 Feb 1973] 05620/74 Heading D1F In a method of heating a running continuous synthetic filament or yarn e.g. in a false-twist crimping machine, the filament passes in a linear or arcuate path axially through a well, in and extending the length of a heated block, from opposite walls of which 0.6 mm or less spent heat is transferred by conduction and radiation and convectively by fluid preheated in the well and flowing transversely to the direction of filament passage at a maximal speed of 3m per second where it contacts the filament, the temperature of the walls and the fluid being maintained below the melting point of the filament. The filament is oscillated as by means of driven cams or guides near the entry to and exit from the well, Fig. 1 (not shown). Fluid flow may be generated by injection into or withdrawal from the well of fluid e.g. ambient air. As shown, a block 2, within a housing 6 and heat insulation 5, comprises heat conductive e.g. metal, slats 10, 11, forming therebetween a well 3 having at least an operative part flattened as at A, a collecting space B from which fluid is withdrawn (together with waste products of the heat treatment) and an inlet space C which facilitates introduction of the filament and into which hot fluid is drawn or injected through pipe 9. A, B and C interconnect along at least part of their length, continuously or by spaced passages. The walls are hard chrome layered as at 13. One or two or a series of several pairs of wells may be formed in a recess between two slats (or by an inlet therebetween) removably. connected into the block or one or more slats may be arranged symmetrically in the recess of the other slat. Inclined grooves may guide fluid and waste into space C. The device may be used for cooling the yarns.

Title: Method of preserving egg-yolks, egg-whites, or both
IPC: A23B5/005
Filed: 1935-02-22
Abstract: Egg yolks or whites or both are preserved by insertion in a sterilized vessel into which carbon dioxide or equivalent gas is introduced before or simultaneously with the egg material, the vessel being hermetically sealed when all the air is excluded. When using small vessels, these are sterilized, dried and introduced into a large container to which carbon dioxide preferably under pressure and after being dried with calcium chloride is supplied, displacing the air.  The egg material is then added and the vessels are sealed.  The eggs are preferably sterilized before being shelled.  In large scale operation, the egg material is added to a sterilized and dried storage vessel simultaneously with the carbon dioxide with which it is mixed by mechanically heating it in a container with the gas or by introducing the gas into it under pressure.  The egg material may be pasteurized at a temperature up to about 63 DEG  C., after treatment with the gas and before the vessel is sealed.

Title: Method and device for the linear interpolation of fine divisions
IPC: G01D5/245
Filed: 1959-02-19
Abstract: 909,644. Electric selective signalling systems. BUDNICK, G. A. A. Feb. 19, 1959 [Feb. 24, 1958], No. 5755/59. Class 40 (1). In a system for measuring relative displacement using MoirÚ fringes produced by slightly inclined diffraction gratings extra pulses are interpolated between successive fringe patterns in order to give greater precision. In Fig. 1, three photo-cells 5, 6, 7 are arranged between a pair of adjacent fringe patterns in such a way that as the diffraction gratings are moved a grating width relative to each other one of the fringe patterns moves successively over the three cells, thereby producing three pulses and increasing the resolution normally obtained by a pair of diffraction gratings by a factor of three. Where the diffraction gratings are part of a system so designed that the gratings should be moving at a constant relative speed, the extra pulses can be inserted electronically. Thus by using pulses produced by sensing the fringe patterns with a single cell to trigger a sawtooth generator, Fig. 3, and then applying the resulting sawtooth to a circuit such as Fig. 5, which comprises a potential divider of equal resistors 19 and a number of diodes 17 joined to their connections, the resulting succession of pulses across a number of capacitors 21 as the diodes successively conduct upon the arrival of each sawtooth function as interpolated pulses and by being counted can be used to ensure that the relative speed is maintained constant.

Title: Improvements in or relating to pressure vessels
IPC: F22B37/10
Filed: 1943-04-15
Abstract: 564,931. Steam generators. BABCOCK & WILCOX, Ltd. April 15, 1943, No. 6045. Convention date, April 16, 1942. [Class 123 (ii)] [Also in Groups XXII and XXVIII] In attaching a tubular nipple round the opening in a pressure vessel, such as a drum or header of a steam generating unit, a nipple formed with an end terminating in an axial inner peripheral flange is positioned with the flange in the opening, the nipple is welded to the vessel by depositing metal round the outside of the nipple, and the nipple is then bound to eliminate the flange. When all the nipples have been welded, the header is stress relieved in the shop. To the ends of the nipples are welded in the field the steam generating wall tubes and riser tubes. Inspection openings have nipples similarly welded thereto to the ends of which cap closures are welded. An upper furnace side wall header 10 forged from a single billet and with a reduced neck 11 to which a cap 12 is welded has a series of openings 13 for the attachment of the tubes and a series of inspection openings 25. The nipples which may have a uniform inside diameter and a wall thickness gradually increasing towards the header end are externally bevelled at 19 at 45 degrees leaving at the outer end an unbevelled annular inner peripheral portion 21 and having on the inner end an axially projecting inner peripheral flange 22 which fits the header opening and acts as a welding ring or backing-up strip. The flange is pushed into the opening and the nipple fusion-welded in position by weld metal filling the space between the bevelled end and the circumferential surface of the header. The flanged end 22 is then eliminated by boring out to a diameter slightly greater than the outer diameter of the flange. The remaining unbevelled part of the end 21 is then bevelled at 10 degrees to meet the 45 degrees bevel. Stress relieving is then effected. The tubes 15 and semi-spherical end caps 30 are secured in the field to the nipples by bevelling their ends, placing a backing ring 23 in the 10 degrees recesses and then uniting by weld metal. If desired, the nipples may be made of uniform wall thickness from tubular stock or their ends may be formed with a flange 22b of reduced external-diameter so that only the inner end of the nipple need be bored out to receive the flange. The header may be received at 3 2 to provide pockets for additional weld metal. For inspection purposes the caps may be cut . away by acetylene blow-pipes and the plates subsequently reshaped and rebevelled until the nipple is too short, when it is replaced,

[Also in Group XXX] A relay operated by the approach of an iron mass has a magnetic circuit with two (or more) permanent magnets 1, 6 in series with an air gap 4, 5, the magnet 1 being the smaller of the two and being in a second magnetic circuit which includes an armature 7 biased away from the magnet 1 by a contact spring 8. Since the magnet 6, the majority of the flux from which normally passes across a gap 11, is much stronger than the magnet 1, a small increase in the flux in the gap 4, 5 will result in a greater change in the flux through the armature 7 allowing the contact spring to move it and change over the contacts. The magnet 6 may be replaced by two magnets 12, 13 (Fig. 3) in series and the normal flux in the secondary circuit 3<SP>1</SP> may be insufficient to restore the armature after operation, so a D.C. impulse is applied to a winding 19 to reset the armature. In Fig. 5 gaps 20, 21 are introduced into the first magnetic circuit and an electronic device 25 is energized by a winding 24 during rapid flux changes in the second magnetic circuit due either to the passing of a high-speed iron mass or to the armature movement on the passing of a slower iron mass.
