Title: Improvements in protective control equipments for electrical apparatus
IPC: H02H7/00
Filed: 1937-06-10
Abstract: 493,797. Protective cut-out arrangements. HESKETH, H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 10, 1937, No. 16158: [Class 38 (v)] A protective control equipment, suitable for mining apparatus, and of the kind in which a circuit interrupter for the apparatus is remotely controlled through a pilot circuit from a control switch which may be located at or adjacent the apparatus, whereas the interrupter is elsewhere, comprises the combination with the control switch, of a timedelay device having contacts. included in the pilot circuit in series with the control switch and mechanically associated therewith so as to be opened mechanically by or under control thereof after a time delay when that switch is operated from the open or off to a closed or running position and to be mechanically closed or released for closure by the switch when the latter is moved to off position, to gether with a relay having normally-open contacts in a parallel circuit round the contacts of the time-delay device, the relay coil being in or connected with the power circuit so as to cause the relay to close its contacts in response to energization of the power circuit. The drawing shows the application of the invention to a system of the character disclosed in Specification 378,180, in which discrimination between operation by the control switch and fault conditions in the pilot circuit is obtained by means of rectifiers, one of which is shown. Movement of the reversing control switch to either running position F or R first connects the stator to the lines, and then at contacts 18 connects the pilot lead P to the earth sheathing E to close the main circuit interrupter at the gate end. Just prior to closure of 18, the control switch by means of the connection diagrammatically shown at 25, releases the spring 24 of the time delay device 23 which, after a given time, due to a mechanical escapement, opens contacts 22, but meanwhile the lines have been energized, shunt or (as shown) series winding 15 becomes energized, and the parallel contacts 14 are closed and are effective to produce tripping of the main circuit-interrupter if the supply fails. To restore the connections after restoration of the supply, the control switch must be opened to cause reclosure of contacts 22. The invention may have the modified arrangement of gate-end relays 52, 53 disclosed in Specification 419,822. Specification 343,667 also is referred to.

Helical springs; dash-pots. - In a spring suspension for vehicles and of the kind described in Specification 137,040, in which an arm 7 bears against a piston 13 controlled by a spring 8 and a dashpot, the coils of the helical spring 8 are of variable crosssection so that the spring has variable flexibility and the arm 7 is provided with a pin 14 working in guide-grooves 15 in the piston. The middle coils 8<b> of the spring 8 are preferably of greater cross-section than the end coils 8a, the spring shown being formed of an ordinary helical spring with coils primarily of uniform rectangular section, and the spring being turned interiorly to give its coils the desired varying cross-section. The piston 10 is partly filled with glycerine in which the bottom 19 of the piston is always immersed, and an annular valve 17 confined between the bottom of the piston and a plate 20 thereon co-operates with ports 16 in the piston to cause slow downward movement of the piston, regulated by the size of holes 18 in the valve, and faster upward movement.

Title: Improvement in or relating to safety or pressure-relieving devices for pressure vessels
Inventor: WRIGHT HARRY RICHARD
IPC: F16K17/16
Filed: 1957-05-22
Abstract: 861,289. Pressure-relieving devices for fluids. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 4, 1958 [May 22, 1957], No. 16229/57. Class 135. A pressure-relieving device for a pressure vessel comprises a pair of spaced apart bursting discs 6 of, e.g. aluminium sheet, clamped one on each end of a stainless steel flanged member 1 by pressure rings 7. The device, connected at one end to the pressure vessel and at its other end open to the atmosphere, is provided between the discs with a lateral connection (not shown) to a vacuum pump. To prevent parting of the discs in processes where the pressure vessel is evacuated before each operation, the space between the discs is evacuated to a higher degree than the vessel to ensure that at all times the discs are deflected toward each other. When it is necessary that the two discs should rupture substantially simultaneously, the outer disc is made less strong to take account of the lesser pressure difference across the outer disc, i.e. between atmosphere and the pressure in the interspace after the rupture of the inner disc as compared with that across the inner disc.

Title: Improvements relating to the production of ammonium sulphate
IPC: C01C1/242
Filed: 1932-06-10
Abstract: <PICT:0397271/III/1> In the production of ammonium sulphate from sulphuric acid and ammonia, a substantially neutral solution is preparedina neutralizer and is then subjected in a separate vessel to auto-evaporation under vacuum to cayse crystallization in large crystals, the cooled mother-liquors being returned to the upper part of the neutralizer in order to prevent precipitation of salt in the neutralizer.  The vacuum evaporation is due mainly to the heat of reaction developed.  A neutralizer 1 is fed with sulphuric acid through a conduit 3, ammonia through a conduit 5 and cooled mother liquors through a conduit 4.  The neutralized liquor accumulates in a reservoir 2 and passes into an evaporator 6 in which a vacuum is maintained by a pump 14 and associated condenser 13.  The crystallized salt collects on a sieve 8 and cooled mother liquors are returned by a pump 10 to the neutralizer.  According to a modification, an externally heated auxiliary evaporator is added in circulation with the evaporator 6.  According to another modification, a supplementary evaporator with an attached externally heated auxiliary evaporator is provided which receives excess of mother-liquors from the main evaporator.  The attached auxiliary evaporator is heated by means of the steam arising from the main evaporator.
