Title: Improvements in and relating to wobbler type piston pump
IPC: F04B1/29
Filed: 1956-10-19
Abstract: 801,952. Swash-plate pumps. BUDZICH, T. Oct. 19, 1956 [Oct. 28, 1955], No. 31854/56. Class 102(1). ). [Also in Groups XXVI and XXIX] The wobbler member 26 of a swash-plate pump comprises a plate portion 27 having one side 46 in rolling contact with the end plate 47 of the pump housing and the other side connected to a plurality of pistons 25 working in axial cylinders 24, the plate being prevented from rotating by a stud 44. The stem of the wobbler member has an end member 30 which is movable in a radial slot of the driven rotating member 36. The rotating member 36 causes the end member 30 to move in a circular path to impart a wobble action to the plate portion which reciprocates the pistons 25. The member 30 is in contact with a lever 128 pivoted at 127 and carrying weights 125 so that radial movement of the member 30 in the rotating member 36 causes an equal and opposite movement of the weights 125 which reduces the out of balance forces acting on the pump. In operation liquid enters through inlet 51 to the space 22 and passes through conduits 53 in the pistons and non-return valves 48 on the suction stroke and is delivered past non-return valves 50 to the collector ring 54 where it passes through outlet 55. The collector ring 54 is connected through conduit 141 to cylinder ring 142 so that just before the end of the suction stroke high pressure liquid is admitted to the working cylinder 24. This has the effect of closing the valve 48, taking some of the load off the end member 30, and ensuring that the wobbler member 26 remains slightly inclined to the axis of the pump when the pump delivery is zero. The angle of the wobbler member is altered to vary the length of stroke of the pistons by a control stem 29, movable axially, having a ball element 28 engaging bearing 43 fixed to the wobbler. The axial position of the control stem 29 is controlled by two servo-motors (see Group XXIX), one, having a control valve 56, being operable under varying delivery and the other, having control valve 104, being controlled by an hydraulic speed governor 90 (see Group XXVI) driven by gear 88 on the rotating member 36, the two servo-motors being operable separately or together to produce the desired output of the pump.

As shown the cartons are inserted into magazine 21 and pressed towards the left by pressing pawls 65 urged by cables 62 and weights 64. The foremost carton is also pressed against frame 90 by suction admitted at 101, and it is discharged by a lug 23 positioned on and between endless chains 24. The discharge aperture is controlled by arms 122 pivoted at 120 and influenced by cam 134 carried by driving shaft 136. When a lug has engaged a carton, arms 122 are displaced upwards by cam 134 so that the carton passes thereunder and is gripped by rollers 26, 27 and so discharged to machine 18, the latter providing the drive for shaft 136 and for the driving shaft 79 of the chain conveyer. Rollers 26 are thus driven by shaft 136, and rollers 27 are pivoted at 143 and urged at 146 towards rollers 26. Guide frame 90 is pivotally mounted at 79 and adjusted relative to magazine 21 by stud 94.

Abstract: 1466689 EPR spectrometer micro-wave cavities VARIAN ASSOCIATES 18 July 1974 [19 July 1973] 31931/74 Heading G1N An EPR spectrometer has a resonant microwave cavity 11, Fig. 1, provided with a relatively large waveguide 31 through which a sample can be placed in the cavity. The waveguide is so dimensioned that its cut-off frequency is lower than the resonant frequency of the cavity; to prevent energy loss the waveguide is positioned so that its fundamental mode cannot be excited by the currents in the cavity, and it is also removably connected to a smaller hollow waveguide 34 whose cut-off is above the resonant frequency. Small samples can be inserted through the waveguide 34, while larger ones necessitate its removal. To irradiate the sample with light, a set of closely spaced apertures 40-44 are provided, this being suitable for use with a parallel sided beam, e.g. from a laser. The cavity shown is cylindrical, but a similar arrangement of waveguides and light inlets can be used with a rectangular cavity, Fig. 6 (not shown). A second waveguide 31 and smaller waveguide 31 may be provided opposite those shown in Fig. 1.

Title: Method for the preparation of oestradiol from urine of mares
Filed: 1936-11-24
Abstract: Oestradiol and its 3-benzoate is prepared from the urine of mares by a process which comprises subjecting a hydrolyzed extract of urine of mares which has been freed from its ketonic constituents, to the action of benzoyl chloride in the presence of aqueous alkali for a short time at low temperature, followed by esterification of the free hydroxyl group with monochloracetic acid, then formation of the quaternary ammonium salts of these esters by means of tertiary bases, and separation of these salts from other phenolic compounds by fractional crystallization from aqueous solution, and finally isolating the free oestradiol or its 3-benzoate by partial or complete saponification.  In examples, (1) a hydrolyzed extract of the urine of mares which has been freed from its ketonic constituents by means of hydrazo-carboxymethyltrimethylammonium chloride is treated in dioxane solution at room temperature with normal caustic potash solution, and is then shaken for ten minutes with a twice normal solution of benzoyl chloride in dioxane solution.  The alkaline solution is extracted with ether, and the oily residue after the removal of the ether is treated in dioxane solution with monochloracetic anhydride.  The mixed ester thus produced is converted into a quaternary ammonium salt by treatment with trimethylamine in benzene solution.  Water is added and from the aqueous layer the 3-monobenzoate of oestradiol is isolated by fractional crystallization and saponification; (2) the ketone free phenolic portion obtained as in example (1) is benzoylated as before, and then esterified by boiling with monochloracetic acid in toluene. The toluene solution after being freed from excess of monochloracetic acid with bicarbonate is treated with pyridine and worked up as in example (1); (3) the same procedure as example (1) is followed except that monochloracetic chloride is used for the esterification. Specification 431,165 is referred to.

Title: Improvements in recording sound on films

Filed: 1936-11-25
Abstract: 486,117. Electro - optical soundrecording. FIDELITY FILMS, Ltd., and CROWTHER, F. K. Nov. 25, 1936, No. 32281. [Class 40 (ii)] A variable density sound track is recorded at approximately constant amplitude and variations in width are used to indicate volume changes with the exception of sudden changes. A tetrode V1 incorporated in the amplifier is subject to automatic volume control as follows. Transformer T is connected in parallel with the amplifier and when an increasing current flows through rectifier V3 the potential change across R2 reduces the impedance of triode V2 so causing a fall in potential of the screening grid of V1 with a consequent decrease in amplification. The output of the amplifier is connected to the light source used for recording purposes. Variations in width of sound track to represent volume changes are effected by passing the varying anode current of V2 through an electromagnetic device K operating a movable shutter M such that an increase in current increases the width of the recording beam. The inertia of the shutter M renders it unable to follow very sudden changes in volume and by making the time-constant of the A.V.C. system of suitable magnitude these are recorded as changes in density. Thus the variations in width only follow the envelope of the changes in volume.
