Title: Improvements in hydraulic variable pitch propellers
Inventor: FAIRHURST LEONARD GASKELL
IPC: B64C11/38
Filed: 1955-05-05
Abstract: 783,910. Variable pitch propellers. ROTOL, Ltd. May 1, 1956 [May 5. 1955], No. 13106/55. Class 114. A variable pitch propeller of the kind actuated by a double acting hydraulic pitch change motor supplied through coarse and fine pitch conduits comprises a normally open pitch lock valve 5 in the coarse pitch conduit 4, closing means, such as flyweights 7 opposed by a spring 6, for closing the valve when the propeller speed exceeds a predetermined value, a non-return valve 10 in a conduit 9 by-passing the lock valve 5 and arranged to remain closed when the pressure on the motor side of it exceeds that on the other side, and adjusting means for the closing means for adjusting them to close the lock valve when the difference in pressure between that in the fire pressure conduit 3 and that in a drain 16 falls below a predetermined value. The adjusting means consists of a piston 11 in a cylinder 12, one end of which communicates with the fine pitch conduit 3 and the other with the drain 16, the piston having a rod 17 carrying a plate 18 engaging the spring 6 to add to the pressure thereof the above-mentioned differential pressure. If this latter pressure falls below a predetermined value the spring 6 displaces the plate 18 and piston 11 to the left and the flyweights 7 close the lock valve 5. The predetermined value is such that this occurs at a speed about 80 per cent of the normal speed. If the propeller is running at an overspeed, e.g. 8 per cent in excess of that called. for, the flyweights 7 close the lock valve and the motor is supplied through the conduit 9 until reduced speed permits the valve 5 to be opened and coarse pitch fluid to flow normally through it. A second piston 19 and cylinder 21 may be provided to co-operate with the piston 11. The cylinder 21 is connected at one end to the coarse pitch conduit and at the other to drain and the piston rod 20 enages the piston 11, the arrangement evening out transient pressure changes. Specification 737,745 is referred to.

Title: Improvements in or relating to the production of artificial filaments, yarns, straw and the like
IPC: D01F2/28
Filed: 1935-05-03
Abstract: Artificial filaments, yarns, straw, and the like are produced by spinning a solution containing an organic derivative of cellulose and finely divided agar-agar.  The materials so produced may have their lustre further reduced by treatment with hot aqueous media, e.g. at 60 to 80 DEG  C.  The amount of agar-agar incorporated is conveniently from 0,5 to 5 per cent of the weight of the cellulose derivative present.  The agar-agar may be ground dry and incorporated in the spinning solution, or it may first be ground in the presence of a dilute solution of a cellulose derivative.  Other materials such as pigments, fillers, dyes, lakes, fire retardants, plasticizers, sizes, and lubricants may be added to the spinning solution.  In an example, agar-agar is milled with a 6 to 10 per cent solution of cellulose acetate, and sufficient of the mixture is added to a solution of cellulose acetate in acetone to form a spinning solution containing 26 per cent of cellulose acetate and 3 per cent of agar-agar.  The fabric obtained by spinning and weaving is submitted to the action of an aqueous soap bath.

Title: Improvements in electro-magnetic vibrating systems
IPC: B06B3/00
Filed: 1935-05-03
Abstract: 456,339. Reciprocating motors; converting. WEYANDT, C. S., 3615, Superior Avenue, Cleveland, Ohio, U.S.A. May 3, 1935, No. 13213. Convention date, Dec. 20, 1934. [Classes 35 and 38 (ii)] [See also Group XXXVII] In a vibrating electric motor for screens &c. of the type in which alternate half-waves of an alternating current are suppressed by a thermionic valve means are provided for allowing the heating-current of the valve filament to flow for a certain time before the main platecircuit is closed. For this purpose the main circuit includes a mercury switch 57 mounted in a disc 49 which can be rotated by a motor (not shown). The valve filament 43 is heated by the current from the secondary of a transformer 30, the primary of which is in two sections which can be thrown into series or parallel by switches 24, 26 and which is controlled by a main switch 3. The switch 3 carries a bar 21 pivoted to which is a rod 22 passing through a hole in a bar 50 attached to the plate 49, so that when the switch is opened the plate is turned through an angle of about 30‹, but when the switch is closed the plate remains unmoved. When the plate is thus turned the switch 57 is opened and a mercury switch 55 in the circuit of the motor closed. The motor then rotates to bring the plate into the position shown, when the motor circuit is broken by the switch 55, and the plate circuit of the valve closed through the switch 57. The vibrator comprises an E-shaped core 59 with a winding 70 having a number of tappings connected to contacts 77 .. 80 over which moves a switch arm 83, so that different numbers of turns can be put in circuit. The armature 60 is mounted adjustably on a piece 61 held between springs 62, 63 the tension of which can be regulated by a screw 65. The disc 49 may carry two switches 57 controlling the circuits of two valves which may supply vibrations for a screen and a feeding device respectively. The two valves may be so connected that one passes one half-cycle of the current and the other, the other.
Patent GB-133021-A (GB)
IPC: B21K15/02
Abstract: 133,021. Dansk Staalbeholderfabrik Aktieselskab. Sept. 27, 1918, [Convention date]. Horseshoes. - In a machine for making horseshces, the work is retained against an anvil by an upwardly and downwardly movable presser-foot, while it is bent into shape and the calks and clips formed. The bar 18 is bent round a grooved former, the groove being formed by the raised part 13 of an anvil 12, and a presser foot 15, the part 13 being of shape corresponding to the inner face of and the presser foot the outer face of the horseshoe. The bending is effected by jaws 16 pivoted at 17 and connected by links 24 to a sliding head 25 operated by a lever 29, adjustable connecting-rod 30, and crank-pin 31 from a shaft 7 rotated by gearing 5, 6 from the driving shaft 4. The jaws are shaped so that the points of contact between the jaws and the bar move towards the ends of the bar. The forward ends of the jaws correspond in shape to the outer side of the horseshoe. The presser foot is carried by a rod 14 held in contact by a spring 43 with a cam 47 on a shaft 10 oscillated b y a pair of cranks 37, connecting-rods 36, and arms 35. The calks are formed, while the work is still held by the presser foot, by a roller 20 of double conical form carried by a rod 21 connected by a link 34 to the cam 47. Simultaneously with the formation of the calks, metal is pressed up to form the clip by a roller 23 in the forked part 38 of a rod pressed by a spring 41 into contact with a double crank-arm 32, shaped so that the first part of the upward motion is effected quickly but the latter part slowly to produce the clip. The lateral pressure exerted on the roll is received by two brackets 42 along which the fork slides. The blank may be formed originally with a scallop so that the clip may be produced without weakening the finished shoe. The finished shoe is removed from the machine, and is then provided with the nail groove and holes, being first, if required, subjected to a second pressing. The Specification in the original form as open to inspection under Sect. 91(3) (a) describes a modification in which the horseshoe is formed from a blank of uniform width, the bending and tapering being performed simultaneously by replacing the jaws 16 by pairs of rolls, one roll of each pair moving on a guiding-member arranged round the former and the other pressing the blank round the former and tapering the ends. This subject-matter does not appear in the Specification as accepted.
