Title: Improvements in or relating to centrifugal compressors and blowers and the like and methods of regulating the same
IPC: F04D27/02
Filed: 1926-08-03
Abstract: 256,278. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Aug. 3, 1925, [Convention date]. Regulating or controlling. - Centrifugal compressors or blowers working at a constant speed are regulated for practically constant pressure between the points ED on the characteristic diagram, the point D being near the pump limit; between the point D and the point C on the pump limit curve the pressure varies in accordance with the pressure volume curve. The suction conduit b of the compressor a has a throttle valve c operated by an oil motor m controlled by a pilot valve l; the pressure conduit e has a non-return valve f and a bye-pass conduit g with a nozzle h for the prevention of pumping when the valve f is closed. The pipe i connects a diaphragm pressure regulator k to the pressure conduit and its piston is connected to the oil valve l and the operating rod of the throttle valve. When working the pump between the points DE a diminishing load causes an increase of pressure and this raises the diaphragm of the regulator k, thus causing the throttle valve c to be moved towards its closed position. The throttle is only responsive to the regulator until the diaphragm reaches the stop p, which can be set by means of the hand-wheel o; from this point the compressor works on the pressure volume curve y corresponding to the position of the throttle valve. When the machine is working at the point C the valve f closes and air returns through the nozzle h, the bye-pass conduit g and the compressor and the pressure falls until the point D is again reached. Then with falling air pressure the throttle valve again becomes responsive to the regulator k, the compressor delivers into the system and the return flow is stopped. The pressure of the spring n of the diaphragm regulator can be varied by means of the hand-wheel q.

Abstract: 1,254,092. Preparing N 2 -dichlorophosphoryl creatinine. UGINE KUHLMANN. 23 April, 1970 [23 April, 1969], No. 19413/70. Heading C2P. N 2 -Dichloro-phosphoryl creatinine is obtained by phosphorylating creatinine with POCl 3  at a temperature below 105‹ C. The phosphorylation may be carried out in the presence of an inert organic liquid, e.g. 1,2- dichloroethane. The insoluble creatinine hydrochloride formed may be recovered either by filtration of the reaction mass or by first evaporating the reaction mass, extracting the N 2  - dichlorophosphoryl creatinine from the evaporation residue with a solvent, e.g. 1,2- dichloroethane, and then filtering the residue. The recovered creatinine hydrochloride may be treated with a concentrated solution of ammonia to recover its creatinine content. The N 2 - dichlorophosphoryl creatinine which may be recovered either in solid form or in solution in the solvent may be converted into the disodium salt of phosphocreatinine by treatment with NaOH. The disodium salt is useful as an antifatigue agent or for feeding livestock to stimulate the growth of animals.

IPC: B60B30/06
Filed: 1960-06-01
Abstract: 927,467. Tyre mounting equipment. J. BROCKHOUSE & CO. Ltd. May 26, 1961 [June 1, 1960], No. 19433/60. Class 144 (1). In a tyre mounting and dismounting apparatus the wheel 8 is supported horizontally on a flanged inverted conical member 6, carried by a vertical fulcrum port 2, by means of an inverted conical clamping member 13 slidably received on the port 2 and held against axial displacement away from the wheel by an adjusting member 17 which is also slidably received on the post 2 and held against axial movement away from the member 13 by means of a pin 20 engaged in the appropriate one of a series of transverse holes 19 through the post 2, the members 13, 17 having co-operating helical cam surfaces 15, 16 whereby rotation of the adjusting member 17 effects final clamping of the wheel on the member 6 by the member 13. As shown, the post 2 comprises a tube 3 welded to a base-plate 1 and extended by a solid post 4 pinned within its upper end by a pin 5. The wheel-supporting member 6 is sleeved on to the post 4 and is radially ribbed at 10 for strength, a slot 9 being provided therein to receive a pin 11 carried by the clamping member 13 and engaged through a hole in the wheel body to prevent rotation of the wheel on the support. The cam surface 15 is formed on the end of a boss upstanding from the lower end of the clamping member 13 and lying wholly therewithin, and the adjusting member 17 is radially winged to facilitate manual rotation thereof. For use with wheels having non- standard wheel centres, an adaptor plate 23 may be pinned to the flange 7 of the support 6. A bead-breaking tool 34, Fig. 5, for use with the apparatus comprises a lever 35 with a hook 36 at one end for engagement in one of a series of holes 37 in the tube 3, and a handle 42 at the other end, a pair of spade-carrying bars 39 being pivoted to the lever towards the hook end thereof whereby, with a tyred wheel located by a stud 41 on the base-plate 1 and the lever hook engaged in a suitable hole 37, the spade 40 depends into engagement with the tyre bead for bead-breaking operation by the lever 35, as shown in Fig. 7. Loops 43, 44 welded to the tube 3 serve to support the bead-breaking tool 34, and also the conventional tyre manipulating tool 26, Fig. 2, when not in use.

Washing, processes for.-In washing or cleaning wool, in an installation in which the wool travels continuously through a succession of baths each followed by squeezing-rollers or other liquidextracting means and a steady circulation of liquid is maintained without periodical stoppages for cleaning the baths, losses of concentrated suint liquor are diminished, and unavoidably lost suint liquor is recovered and re-utilized to such an extent that the concentration of suint liquor in one or more baths is maintained substantially high and constant solely by means of the suint supplied to the installation by the wool under treatment. Impurities are removed from the baths with a minimum loss of liquid by the methods described in Specifications 221,521 and 234,055, the impurities then being in the form of solid mud and slightly moist wool grease. Liquid containing little or no suint is passed through the raw wool, and after purification and concentration, for example by evaporating or by circulation through the system, is utilized in the concentrated bath. Liquids poor in suint in the subsequent baths are not run into the concentrated bath, but are run out of the set. Two or more concentrated baths containing successively cleaner liquors may be used. Specifications 240,477, 240,482, 240,499, and 243,360 are referred to.

A bracket 29 is welded to the closed end of the tube 19 and is formed with an arcuate slot 28. A link 27 connects the bracket 29 and a pivoted arm 20, rotation of which operates a pointer (not shown). A second arcuate slot 30 is formed in the arm 20 and the link 27 can pivot about pins R, Q, which are adjustably mounted in the slots. In setting up the instrument, the pins R, Q are placed at the mid-points of their adjustments, in which position R, Q are the centres of curvature of the slots 30, 28, respectively, and the pressure difference acting on the tube is reduced to zero. The pointer is then adjusted to read zero. The pressure difference is then increased to its maximum value and the position of the pin Q adjusted until the pointer reads this value correctly. The pressure difference is then reduced to half the full-scale deflection and the pin R adjusted. If necessary, the procedure may be repeated. The arcuate slots may be replaced by straight slots in each of which travels a nut moved axially by a captive screw. The linkage may be applied to other apparatus with condition responsive elements, such as a bellows, a diaphragm or a bimetallic strip.
