Title: Improvements in or relating to shaft seals
Inventor: BARRETT TERENCE
IPC: F16J15/40
Filed: 1957-02-04
Abstract: 827,015. Stuffing-box substitutes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 3, 1958 [Feb. 4, 1957], No. 3841/57. Class 122 (5). A shaft seal for effecting a seal against gas under pressure by means of oil or other liquid comprises two relatively - rotatable smooth-surfaced members arranged face-to-face, and two series of viscosity grooves separated by a continuous ungrooved surface formed in the surface of one of the members for generating a pressure in the sealing liquid upon relative rotation of the members, the arrangement being such that a greater liquid pressure is generated in the series of grooves on the gas pressure side than in the other series. The two members may be in the form of annular plates and the Figure shows a portion of the grooved surface of one plate which is mounted on the casing of the device and urged, by a spring, into contact with the smooth surface of the other plate which is driven by the shaft. The grooves 4, 5, of opposite hand, are formed in concentric bands 1, 3 and separated by the ungrooved band 2, the width of the bands or the dimensions of the grooves being so proportioned that when, during operation, liquid such as oil is fed through holes 7 formed in the grooves 4, an oil/ gas interface 8 is formed in the grooves 5; the interface may be arranged close to the band 2 in a position of minimum friction between the plates. When the device is stationary, the seal is formed by the contact of the ungrooved band 2 with the surface of the mating plate but, during operation, a small working clearance, which may be varied by adjusting the spring pressure, is formed between the plates. To overcome this pressure on starting, oil may be pumped through a number of holes 6 formed in the ungrooved band 2 in order to jack the plates apart. Alternatively, the spring loading may be relieved. The seal may also be applied to a cylindrical-type seal.

Title: Improvements relating to phase sensitive electric circuits
Inventor: MANSFIELD GERALD ROLAND
IPC: F41G7/24
Filed: 1954-03-09
Abstract: 825,280. Phase-sensitive circuits. FAIREY AVIATION CO. Ltd. June 9, 1955 [March 9, 1954], No. 3859/54. Class 38 (4). In an electric circuit for deriving a function of a signal wave in a given phase relationship with a reference wave, switching-valves 2, 3 are controlled by the reference wave input R so that in each half cycle one valve conducts and the other is cut off and an output is obtained at 5 that is propor. tional to the signal input S but in the same sense as the reference wave at any instant. Valve 2 is controlled directly by the reference wave and in turn controls valve 3, there being a feed-back from the screen of 3 to the control grid of 2 which increases the speed of switching of valve 2. Fig. 3 illustrates the use of reference-wave amplifying valves 33, 34 which produce sufficient voltage (e.g. R2) swing to ensure correct switching of valves 2, 3 by swamping the signal wave S. In this embodiment the output is taken from the anodes at 30 and the earthed centre tap of a resistor 28 as shown or of a secondary winding energized by S. Fig. 4 (not shown), illustrates a modification with improved stability and with the cathode of 2 connected to the anode of 3. In further modifications, Fig. 5 (not shown), and Fig. 7, the signal wave is amplified by valves 44, 45, with or without cathode followers 71. Outputs corresponding to the sine and cosine of the phase angle between the reference wave and the signal wave are obtained by applying the reference wave to one phase-sensitive circuit with a small phase correction and to a duplicate circuit through a phase-shifting circuit as shown in Fig. 6.

Abstract: 1508073 Switching circuits DAINI SEIKOSHA KK 3 Feb 1976 [10 Feb 1975] 04200/76 Heading H3P  A circuit in which the condition of a plurality of outputs 32, 33 is determined by the sequence in which mechanical switches 18, 19 are operated includes at least one memory circuit. Assuming both bistables 29, 30 are in the reset state, then if switch 19 closes first bistable 29 is set to provide a "1" at one input of AND gate 26 and a "0" at one input of AND gate 24. When switch 18 closes, it is inhibited from setting bistable 30, but provides a second "1" input to AND gate 26, giving a "1" output at 32, and a "1" at one input of AND gate 23, via OR gate 31. When both switches 18, 19 are open, NOR gate 21 provides a second "1" input to AND gate 23, and the resulting "1" output resets bistable 29. If switch 18 closes first, a similar sequence of events energizes bistable 30 resulting in a "1" output on line 33. The arrangement may be used for setting time and date in a timepiece.

Filed: 1926-02-17
Abstract: 248,726. Bakelite Ges. March 6, 1925, [Convention date]. Addition to 247,956. Phenol-aldehyde condensation products.-The process for purifying phenol-aldehyde condensation products described in the parent Specification is modified by using, instead of caustic alkalies, other metallic oxides or hydroxides capable of reacting with or combining with phenols. The oxides or hydroxides of calcium, barium, strontium, magnesium, aluminium, copper, zinc or nickel may be used, either alone or in admixture, or in combination with alkalies, e.g. as sodium aluminate, potassium zincate, or sodium zincate. The molecular or additive compounds of the oxides or hydroxides with sugars, alcohols, or the like may also be used, as well as the ammonia double compounds or amino compounds. The molecular or chemical compounds of the metallic hydroxides with alkalies, ammonia, or organic bases, e.g. pyridine, may also be formed during the reaction by adding alkalies, followed by addition of the metallic hydroxides, or by adding the hydroxides, ammonia or organic bases, separately. Any excess of oxides or hydroxides may be separated by filtration or other means, or may be allowed to remain to act as a filling ingredient. Organic solvents, e.g. alcohol, methyl alcohol, acetone, or ether or mixtures thereof, may also be added. The purified resin is precipitated by adding water or an aqueous solution of a hydrotropic substance, e.g, sodium salicylate or an alkali or ammonia soap, including soaps of the various fatty acids, resinic acids, wax acids, sulphonated or halogenated fatty acids, or hydroxy fatty acids, either alone. or in mixture. The process may be carried out in the presence of filling ingredients, e.g. wood meal, glass powder, asbestos fibre or powder, cotton, wool, or silk. In an example, phenol-formaldehyde resin, in lumps, is treated, in a ball mill or stirring apparatus, with milk of lime. The resin is reduced to a powder, which is filtered off and washed with water or aqueous liquids. The first filtrate is treated with hydrochloric acid, to recover the phenol extracted from the crude resin.
