Title: Improved steam heating system for buildings and apparatus therefor
IPC: F24D1/00
Filed: 1928-09-03
Abstract: 323,503. Jackson, L. Mellersh-, (Warren, Webster, & Co.). Sept. 3, 1928. Heating buildings.-Steam is supplied from a boiler 10 to a horizontal main 11 having vertical branches 12 each supplying groups of radiators 14. The main steam supply is controlled by a valve 16 and an apertured disc 17, so that the quantity of steam is less than sufficient to fill all the radiators under medium temperature conditions. A similar apertured disc is arranged in a fitting 26 in a pipe supplying the branch 12, the aperture being of such size as to compensate for the drop of pressure due to the distance of each branch 12 from the main control 17. A similar apertured disc is also arranged at the inlet of each radiator, the aperture being of such size as to compensate also for the decrease in atmospheric pressure due to altitude, and the decrease in pressure of steam due to the height of the column. The discs are readily interchangeable. The valve 16 is regulated manually according to the total steam requirement due to weather conditions, and the consumption of the various parts of the system is then automatically proportioned by the apertured discs. The adjustment is arranged to be correct at about half load, and is approximate at other loads. The main adjustment may be by regulating the valve 16 to control the pressure in the chamber 18, or by employing a disc with a variable aperture controlled by a slider. Two forms of apertured disc fittings are shown in Figs. 2 and 3, and Fig. 4 illustrates an apertured disc 86 with an elongated rectangular opening 77 controlled by a slider 88. Reference has been directed by the Comptroller to Specifications 13516/85, 21898/04, 15163/12, and 14181/14.

Abstract: 732,457. Making heat exchangers. VICKERS, W. C., and RUSTON & HORNSBY, Ltd. Oct. 7, 1953 [Oct. 9, 1952], No. 25317/52. Classes 83 (2) and 83 (4). Stamping.-A method of making hollow metal elements in the form of flattened pods for heatexchangers comprises joining two similar flat metal sheets or the two similar parts of a single flat metal sheet folded about a centre line, along their or its edges by welding or brazing, heating the element thus formed to the plasticizing temperature between rigid flat or suitably shaped limiting plates and inflating the element with gas, e.g. nitrogen under pressure. Apparatus comprises a frame 10 on which is fixed a lower limiting plate 11 carrying spacer blocks 14. An upper limiting plate 12 is hinged to the plate 11 at 13 and is clamped against the spacer blocks by bolts 15 and wedges 17 carried on a sliding plate 18 actuated by a lever 19. The opposed faces of the plates 11 and 12 are faced with heat and electrical insulating material 20 and 21 respectively. An element 47 welded along its edges and along seams 48, 48a, 48b (Fig. 4), is placed between the plates and the end portions 50 are clamped between fixed lower clamping blocks 22, 23 and movable upper clamping bars 24, 25 mounted on side arms 26 pivoted to the frame. The arms 26 have extensions 30 carrying contact members 31 for establishing electrical connection between the blocks 22, 23 and bars 24, 25. For heating the element current is supplied from a transformer 32 whose upper terminal plate 33 is connected to the lower clamping block 23 and whose lower terminal plate 34 is connected to copper bars 37 resting on rollers 38 supported by the frame so as to accommodate expansion of the element. After heating, the element is inflated by compressed gas supplied to a pipe 41 inserted in the element. After withdrawing the formed element from the clamping plates it is cooled and the closures 49a of the inlet and outlet portions 49 and the inflation tube 41 are cut off, the hole left by the tube being plugged. The seam welds 48b may be replaced wholly or in part by spot-welds.

Abstract: 1,045,393. Fluid memory devices. SPERRY RAND CORPORATION. June 16, 1965 [June 29, 1964], No. 25365/65. Heading G4B. A dimple 18 (Fig. 1, not shown), may be switched from one state representing for example a binary " 0 " to a second state representing a binary "1" by fluid pressure from an orifice 12 in a tube 11. The state of the dimple may be read out by applying pressure to a similar tube 13, the orifice 14 being restricted when the dimple is adjacent the tube to give a high reading on a manometer 16 whilst when the dimple 18 is in the position shown there is no restriction and a low reading is obtained on the manometer. The tube 13 may also be used for returning the dimple 18 to its original state. In the embodiment described, a plurality of such dimples are arranged in a three-bythree matrix to form a memory, each row representing a word of three bits. AND gates A-I (Fig. 3), are each associated with a dimple so that when there is an input on each of the lines 23, 24 to an AND gate the associated dimple changes from its " 0 "state to its " 1 " state. Each word may be read out by applying a pulse to one of the lines 38, 39, 41, high output pulses on the lines 42, 43, 44 representing a binary "1" and low output pulses representing a binary " 0."

Title: Improvement in manufacture of threaded containers
IPC: B65D35/08
Filed: 1939-09-07
Abstract: 532,567. Moulding threaded containers. MONSANTO CHEMICAL CO. Sept. 7, 1939, No. 25367. Convention date. Sept. 16. 1938. [Class 87 (ii)] Moulded containers such as thin-walled collapsable tubes, of organic plastic materials, having screwthreaded portions, are formed with internal lugs L to be engaged by a suitable tool for unscrewing the container from the mould in which it is formed. The lugs may extend down the internal sides of the container, and the moulding plunger may be used as the unscrewing tool, though a separate tool, used after withdrawal of the plunger, is preferable. In the case of a bottle of uniform internal diameter, outside threads can be moulded around the mouth and the lugs can be formed by grooves or projections in the bottom. Specified moulding materials are cellulose esters, e.g. cellulose acetate, and vinyl, urea-formaldehyde and phenol-formaldehyde resins.

Title: Improvements in or relating to valves for controlling the flow of fluids
IPC: F16K1/12
Filed: 1958-08-07
Abstract: 923,023. Valves. FLIGHT REFUELLING Ltd., and P. S. MACGREGOR. July 28, 1959 [Aug. 7, 1958], No. 25395/58. Class 135. A valve plunger 12, Fig. 1, is urged on to a seat 7 by a spring 13 and fluid pressure from the inlet 10 which leaks past the plunger 12 to a chamber 14; a disc closure 19 is also urged by a spring 30 to close a port 16 through a transverse wall 15 in the plunger. Upon energizing a solenoid coil 5 the armature 6 thereof moves rightwardly whereupon the frustoconical part 26 of an associated thrust rod 18 forces balls 27 outwardly into wedging engagement with a frusto-conical surface 24 on a head 23 so unseating the closure 19 and relieving the pressure in chamber 14. The closure 19 is further opened when the rod 18 abuts the end of a bore 25 in the stem 20 of the closure 19. Upon the head 23 engaging a spider 22 in the plunger 12 the latter is readily unseated since opening of the closure 19 equalizes the pressures across the plunger. When the coil 5 is de-energized springs 13, 30, 28 restore the parts to the positions shown. The plunger 12 may also be manuallyoperated through a cam 31, sleeve 38, spring 39, cap 41 and a plunger 43 abutting the armature 6; the cam 31 provides for a longer stroke than is required to open the valve, the excess movement being absorbed by the spring 39 which allows the lost-motion of the sleeve 38 relative to the plunger 43. The plunger 12 may control a main shut-off valve by controlling the connection between a control chamber in the latter and the downstream side of the main valve, the control chamber being connected through a restricted passage to the upstream side of the valve.

Title: Gyromagnetic resonance methods and apparatus
IPC: G01R33/46
Filed: 1957-08-14
Abstract: 867,843. Gyromagnetic resonance apparatus. VARIAN ASSOCIATES. Aug. 14, 1957 [Aug. 29, 1956], No. 25696/57. Class 37. In apparatus for measuring the gyromagnetic resonance frequency of a set of gyromagnetic bodies 8 the alternating magnetic field applied to the transmitter coil 9 is derived from a further set of gyromagnetic bodies 4 in order to compensate for fluctuations in the common polarizing field H o . The receiver and transmitter coils 5, 7 of the set of gyromagnetic bodies 4 are coupled to the input and output, respectively, of an amplifier 6, the combination acting as a regenerative oscillator circuit. The gyroresonance spectrum may be swept by varying the polarizing field of the set of gyromagnetic bodies 8 by means of modulating coils 12, or by varying the frequency of the alternating magnetic field, e.g. by modulating the polarizing field of the set of gyromagnetic bodies 4 or by heterodyning a reference frequency against a cyclically variable low frequency signal, filtering out the desired sideband and applying this sideband to the set of bodies being swept. A modulating magnetic field may be applied to both sets of gyromagnetic bodies, but in opposite phase. The sets of gyromagnetic bodies 4 and 8 may be rotated to average out small inhomogeneities in the polarizing magnetic field. Instead of utilizing crossed-coil nuclear magnetic resonance systems, the invention may utilize single coil twin T-bridge or other single coil absorption systems. A free precession technique may be utilized for exciting gyromagnetic resonance instead of utilizing an R.F. source.
