Patent GB-940233-A (GB)
Title: Dynamo-electric machines
IPC: H02K19/06
Filed: 1961-02-27
Abstract: 940,233. Dynamo-electric machines. J. JARRET, and J. JARRET. Feb. 27, 1961 [Feb. 29, 1960], No. 7086/61. Heading H2A. In a dynamo-electric machine, for example an inductor alternator or a synchronous motor the rotor comprises alternate projecting laminµ 2 (Fig. 2) of high purity iron separated by silicon steel spacers 10, the projecting laminµ 2 being magnetically saturated in use at a value of magnetizing field much lower than that at which the other magnetic parts of the machine are saturated. The Specification alleges that since the maximum torque of a machine is dependent on the amplitude of the flux variation (from a maximum when the rotor and stator teeth are aligned to a minimum when they are out of register) the use of high purity iron projections reduces hysteresis losses, thus allowing a greater field excitation to be used and thus increasing the efficiency of the machine. The description explains with reference to a bipolar synchronous motor (Fig. 2, not shown) how to calculate the ratio of the thickness of the projecting laminµ to the thickness of the spacers. A 4-pole alternator (Fig. 3) embodying the principle of the invention has stator windings 14a, 14b, 14c, 14d interconnected to form an impedance bridge with a D.C. source 17 connected across one diagonal and an A.C. output taken across the other. The invention may also be applied to reciprocating machines.

Abstract: 155,493. Lowden, H. B. March 11, 1920. Drying-furnaces; charges, agitating; hearths.- Flotation concentrates obtained in the treatment of ores, and like materials, are dried upon a hearth arranged above a flue, being repeatedly cleaved in a vertical direction and gradually moved over the hearth by means of rabbles carried upon a rake having a rectangular motion in a vertical plane. As shown, the rake 4, Figs. 1 and 2, having rabbles 5 is connected by uprights 14, 14a, to bell-cranks 12, 13 fixed to rocking-shafts 11, the rocking-shafts being mounted in bearings 10 rigidly secured to the sliding bars 8. The rake is actuated from a shaft 15 through cranks 16, connecting-rods 17 and cross-heads 18. The cross-heads reciprocate in guides 9 rigidly secured to the sliding bars and have their strokes limited by means of adjustable set screws 20. Links 21, 22 connect the arms 13 of the bellcranks to the cross-heads and to one another. The uprights 14a are flexibly connected to the rake so as to allow for expansion, and balance weights 23 are secured to the rake mechanism. A deflector plate is fitted to the rake to prevent wet material falling upon the rabbles. The hearth may be formed in sections, allowance being made for longitudinal and transverse expansion by means of lap-joints and lugs 33 secured to the hearth and sliding in anchor-plates 34. In a modification, in which toggle gears are substituted for the bell-cranks, the rake is provided with uprights 14b, Fig. 4, slidably connected to vertical guide bars 26 which are rigidly secured to the sliding bars 8, the vertical bars and the uprights being connected by links 29 to the crosshead links 21.

Abstract: The process of making polymeric dimethyl silicones as described in the parent Specification is modified to produce polymers of low molecular weight, which process comprises hydrolysing dimethyldiethoxysilicone in the presence of an acid, distilling the hydrolysis product to recover the low polymers boiling below 250 DEG C. at 4 mms. pressure, treating the low polymers so obtained with an aqueous hydrochloric acid and fractionally distilling the product to separate the cyclical polymeric dimethyl silicones having up to 13 Si. atoms per molecule.  The hydrolysis product is preferably washed before distillation, as also is the oil resulting from the aqueous hydrochloric acid treatment.  The acids which are preferably used as catalysts are water-soluble acids such as hydrochloric, oxalic, acetic, and trichloracetic acids. Hydrolysis is preferably carried out at room temperature for about 18 hours.  Curves are included in the Specification to illustrate the fractional distillation, and also the vapour pressures of the polymers.

Abstract: 700,198. Fluid-pressure servomotor control systems. BORG-WARNER CORPORATION. April 10, 1951 [April 13, 1950], No. 8279/51. Class 135 A pressure relief valve comprises a main valve member 12 seated by spring and inlet pressures and opened by a piston 27 when pressure is applied to the lower side thereof under the control of a spring-loaded auxiliary valve member 17 seating on the piston and exposed to inlet pressure through a passage 15. The valve member 17 has an enlargement 34 which is engaged by a stem 36 against which bears an abutment 38 for the adjustable loading spring 32. The upper end of the stem 36 is situated in a chamber which is vented by a passage 63 to the main outlet 7, and the cross-sectional area of the stem 36 is made equal to that of the enlargement 34 less the area of the valve member 17 exposed to pressure in the passage 15 whereby the degree of opening of the valve member 17 is unaffected by pressure in the space below the piston 27. Alternatively, the areas of the stem and enlargement may be varied to obtain desired characteristics. As the piston 27 rises consequent upon opening of the valve member 17 the latter follows the movement of the piston so that the length of the spring 32 is substantially the same whether the main valve member be open or closed. A vent 65 enables the piston to descend when the valve member 17 closes.

Title: Improvements in or relating to ion-exchange and acid-removing materials
IPC: C08G12/08
Filed: 1936-03-20
Abstract: Insoluble resins suitable for use in the treatment of water by anion exchange are prepared by condensing m-phenylene diamine with a mono- or di-saccharide in the presence or absence of a non-sugar aldehyde such as formaldehyde.  The saccharide may be replaced by a polysaccharide which yields a saccharide on hydrolysis.  The diamine is used as its salt.  In examples: (1) m-phenylene diamine hydrochloride is condensed with glucose, l vulose, sucrose, or invert sugar and then with formaldehyde; (2) m-phenylenediamine hydrochloride is condensed with glucose or starch.  The resins, after an initial treatment with an alkaline solution will remove acids from solutions or, if saturated with one anion and then used for the treatment of a salt containing another anion will effect an exchange of anions.  The used resins may subsequently be regenerated.  The Provisional Specifications both refer to the condensation in general of bodies containing one or more amino groups.
