Title: Improvements in or relating to venetian blind ladder webbing and the like
Inventor: FRENCH GEORGE FREDERICK
IPC: E06B9/382
Filed: 1951-05-25
Abstract: 728,385. Woven fabrics. FRENCH & SONS, Ltd., T. May 26, 1952 [May 25, 1951], No. 12262/51. Class 142(4). Venetian blind ladder webbing, having two body webs connected together by two rows of staggered cross straps in which the warp threads forming each cross strap are bound into one body web, then, after a short cross over subsequently to be severed, into the other body web, followed by a long cross over forming the cross strap before binding again into the first body web, is characterised by each cross strap being formed of two sets of warp threads which cross over at different short cross over positions so that at each end of a cross strap one set of threads crosses over immediately after binding-in while the other set continues to be woven with the first body web. In one embodiment the warp is shed so as to produce a ladder web having two body webs woven in twill and two rows of plain woven cross straps in parallel but symmetrically staggered relation. The weft threads A, B, C, D from the corresponding shuttles are shown as lines of dots and a warp thread of each set of threads for one row of cross straps is shown. From the left hand side up to line w-w warp threads f, e are woven with the top and bottom body webs respectively, warp threads h, g being woven with weft thread B to form a cross strap. Between lines w-w and x-x warps e, h, g are interwoven with wefts A, B for the binding-in of the cross strap. At line x-x warps h, e cross over into the top web, warps h, e being subsequently severed at this line. Between x-x and y-y warps e, f, hare woven with wefts B, D as part of the top body web, weft C meanwhile being used to weave a cross strap of the other row. As warps f, h are shed relative to weft C for an even number of picks, weft C is not interwoven by them. To the right of line y-y warps f, e are woven with weft B to make the intermediate cross straps of the first row. At the next binding-in the chart is the same as between w-w and x-x with warps f, e substituted for h, g and vice-versa.

IPC: B60G13/02
Filed: 1930-12-19
Abstract: 375,794. Hinges. CARWARDINE, G., 17, Macaulay Buildings, Bath. Dec. 19, 1930, No. 12418/32. Divided on 372,830. [Class 65 (ii).] In a joint for the connection of two members having a limited relative angular movement, such as in a vehicle suspension system, comprising a cylindrical surface on one member rolling on a plane surface on the other member, an elastic member, such as a spring, is provided adapted constantly to urge the surfaces into engagement with each other. The spring acts on the member having the plane surface to press it towards the cylindrical surface, and does not connect the two parts of the joint. In the form shown, a cylinder 4 is fixed to one member of the joint and a plate 3 is fixed to the other member 2 of the joint and bears against the cylinder ; a housing 9, also fixed to the member 2, surrounds the cylinder 4, the surface opposite the plate 3 having a slight clearance from the cylinder while the other two surfaces have substantial clearance. The first movement of the joint members causes rolling of the cylinder on the plate 3 until the cylinder comes into contact with one of the side parts of the housing ; subsequent movement causes slipping of the cylinder on the surfaces of the housing, and frictional resistance to this movement may be provided by lining the side parts of the housing with friction material 11. In order to hold the cylinder and plate constantly in engagement when the load on the joint does not perform this function, a spring 12 is provided between two parts of the member 2 to press the plate 3 against the cylinder. Specifications 263,925, [Class 108 (ii), Road vehicles, Undercarriage details &c. for], and 372,830, [Group XXXII], are referred to.

Title: Extraction of oil from nuts and seeds
Inventor: DUNNING JOHN WALCOTT
IPC: C11B1/04
Filed: 1950-05-18
Abstract: A process for extracting oil from nuts and seeds of high oil content by solvent extraction without production of a large amount of fines comprises mechanically expressing the material to reduce the oil content to about one-fourth the protein content, commnuting into fragments to pass half-inch openings, subjecting the fragments to the action of flaking rolls to convert into wide, thin flakes from .005 to .02 inches thick, and solvent extraction of the flakes.  The oil content is preferably reduced to from 8 to 18 per cent of the total weight of material after the mechanical expressing step, and the moisture content of the comminuted fragments adjusted by means of live steam and by heating to a temperature of from 145 DEG F. to 200 DEG F. to form 10 to 20 per cent of such weight.  The flakes may be extracted with hexane or with methanol.  In one test it was found that after violent agitation of the flakes with hexane, the supernatant solvent contained only one-quarter of the amount of fines occuring with unconditioned press cake.  Examples of the extraction of flax seed and of decorticated peanuts with hexane are given.

Abstract: 117,336. British Westinghouse Electric & Manufacturing Co., (Westing- house Electric & Manufacturing Co.). Aug. 30, 1917. Rotary converters; alternating-current commutator and induction machines; exciting.-Relates to rotary phase-converters, particularly of the T- connected type, having a primary stator winding 13 and a secondary stator winding 14, and consists in preventing unbalancing by impressing upon the rotor winding 15 electro-motive forces having double the frequency of the primary mains and derived from one or more exciting machines; these machines are driven either from the converter shaft or by an independent alternating-current or continuous-current motor so as to rotate in synchronism with the converter. Several arrangements are described in the Specification. Fig. 1 shows one arrangement in which the rotor of the phase-converter has a two-phase winding 15 connected through slip-rings 18 to the machines 11, 12 of the compensated series commutator type; a single machine 23, Fig. 3, having separate armature windings and adjustable field-magnet windings 26, 27 may be used, being driven by a repulsion motor 28. Exciting machines of the induction type having short-circuited commutator brushes, or polyphase slip-ring or commutator machines, Fig. 13, may be employed. The rotor of the converter may be provided with a Y-connected winding 47, Fig. 7, two of the branches being joined through an impedance 48; two branches are connected to a single-phase exciter 49. The rotor of the converter may carry, in addition, a squirrel-cage winding, and, to eliminate slip-rings, the rotors of the converter and exciter may be combined into an integral structure. To improve the power factor of the converter, a continuous-current excitation may be impressed directly or indirectly upon the rotor. As shown in Fig. 13, the armature of a commutator machine 82 excited by continuous-current may be connected in one of the leads joining the rotor winding 15 of the converter with its polyphase exciter 81; the field magnet of the machine 82 carries a short-circuited winding 85 to eliminate the action of the alternating cross-field. The machines 81, 82 may be combined in one structure. Continuous-current machines may be introduced into various parts of the alternating-current system, transformers being employed to neutralize the effects of alternating current in the continuouscurrent circuits. Fig. 25 shows an arrangement in which an auxiliary phase-converter 139 operating from the same source as the main converter 10 is employed to produce the exciting-current for the main converter. Adjustable resistance 146 and reactance 148 are provided in the secondary circuit 141 of the auxiliary converter to vary the compounding of the machine 10. The main and auxiliary converters may be combined, for example, as shown in Fig. 27.
