Title: Improvements in fluid circulating apparatus for knitting machines
IPC: D04B11/00
Filed: 1944-07-04
Abstract: 593,465. Cooling systems for knitting-machines. DEHN, F. B. (Textile Machine Works). July 4, 1944, No. 12726. [Class 64 (iii)] [Also in Groups VIII and XXVIII] A pulsating flow of fluid through a closed circuit, temperature modifying system including a hollow reciprocating rod 16 [the friction rod of a full-fashioned knitting machine; see Group VIII] is produced by imparting motion to the fluid in the rod upon movement of the rod in one direction, reversing the direction of travel of the rod as the momentum of the fluid in the first direction effects displacement of the fluid relative to the rod, and preventing reverse flow of the fluid in the rod, as by a one-way valve 84, Fig. 1. The fluid is supplied from a reservoir 70, and is taken to and from the rod by stationary pipes 74, 72 and hoses 76, 75, this part of the circuit acting as a radiator in the case of a cooling circuit. The valve 84 is provided with a manual control. A second valve 83 facilitates replenishment of the circuit with fluid. In a modification, Fig. 7, two check valves 97, 103, are provided and the return pipe ends in a gooseneck in an elevated reservoir 90. A reservoir having a glass level tube may be used; and the fluid may be drawn off from the reservoir by a siphon which dips to such a point that surface scum and sediment are both avoided. Specification 423,836, [Group VIII], is referred to.

Title: Desulphurisation of petroleum fractions
Inventor: MCLEAN DONALD HENRY
IPC: C10G29/20
Filed: 1952-05-20
Abstract: The elemental sulphur content of a petroleum white spirit is reduced by heating a mixture of a major proportion of the white spirit with a minor proportion of a terpene or mixtures of terpenes.  Terpenes specified are monocyclic terpenes, e.g. dipentene.  The terpene reacts with the sulphur present and this reaction may be accelerated by adding catalyst for example rubber accelerators such as mercaptobenzthiazol and diphenyl guanidine. The mixture may be heated to 150-200 DEG C.  The mixture after heating may be washed with a caustic or alkali such as caustic soda.  The white spirit may be one that has been sweetened by treatment with sodium hypochlorite.  The process is compared with a number of conventional processes.  The Provisional Specification refers to the treatment of petroleum fractions in general.

Title: Improvements in or relating to helicopters
IPC: B64C1/00
Filed: 1944-07-07
Abstract: 601,014. Helicopters. ATREX MANUFAC TURING CO., Inc. July 7, 1944, No. 13018. Convention date, May 3, 1943. [Class4] In a helicopterrotor in which the bladesare moumted for pitch-change and free flapping movement on a blade-carrying member universally connected to a rotatable support, the rotor is stabilized against tilting, e.g. while hovering, by control means connected between the blades and the support which vary the angle of the blades when there is an angular displacement between the axes of rotation of the support and member so as to increase the lift of the depressed blade and decrease the lift of the elevated blade. As shown, Figs. 3 and 4, applied to a helicopter having two pairs of counter-rotating blades, the drive to the lower rotor comprises a sleeve 23, hub 31 and yoke 32, the latter being pivoted by pins 44, 45 to a gimbal ring 46 pivoted by pins 47, 48 to a housing 49 carrying a collar 51 in which the blades are mounted for pitch-change movement. The blade mounting includes a flexible joint 62 to permit the blade to flap within desired limits. The blades are connected by tubes 65, 66, having bifurcated lower ends, slidable shafts 67, 68 and universal joints 70, 72 to studs 69, 71 which are threaded in arcuate flanges formed on the gimbal ring 66, and are adjustable axially by means of lock nuts. Tilting of the rotor about the axis of pins 47, 48 thus effects a differential adjustment of the pitch angle of the blades, the amplitude of which depends on the adjustment of the studs 69, 71. Tilting about the axis of pins 44, 45 has no effect on the blades. The upper rotor is mounted on a bell housing 78 driven by a shaft 24 through an arm 98 pivoted by pins 94, 95 to a gimbal ring 91 pivoted by pins 87, 88 to a skirt 83 secured to the housing. The blades are connected by gearing 130, 128 and 131, 129 to the bifurcated upper ends of tubes 146, 147 which enclose shafts 114, 115 connected by universal joints 116, 117 to studs 110, 111 threaded in an annular neck 109 of the gimbal rings 91, the studs being adjustable axially by means of lock nuts. A ball-race 107 is provided between the two rotor assemblies, and a spring 134 prevents angular displacement when idling. A plurality of circumferentially spaced holes are provided in the flange and neck of gimbal rings 46 and 91 respectively so that by choosing the appropriate pair of holes for studs 69, 71 and 110, 111, and adjusting the positions of the collar 51 on the housing 49 and the housing 78 on the skirt 83, the angular setting of the rotors relative to their gimbal rings may be varied as required. The rotors are driven through gearing and an over-running clutch.

In a rake-wheel for a side-delivery rake each of the peripheral tines has a leg-portion and a relatively cranked foot-portion, the tine being turnable about the point of connection of the leg-portion and the wheel whereby the foot can be displaced with a movement having a component radial to the wheel axis ; when the tine is so turned, the foot becomes displaced from the point of connection in a direction parallel to the rake-wheel axis, the foot remaining parallel to its original position during the displacement. In one form shown, Fig. 1, the tines are formed in pairs from pieces of wire which are bent at 9 around the spokes 3 of a wheel 1 and have divergent legs 7 terminating in feet 6, the junction of each foot and leg having a loop 10 through which passes an undulating endless resilient wire 11 serving to mantain all the tines in position. The legs 7 extend backwardly from the wheel-rim 4 and the feet 6 lie in a common vertical plane parallel to the wheel-plane, Projections 5 extend forwardly from the rim 4 to engage the mass of the crop. In Fig. 3 the wheel is mounted on an axle 21 extending from a frame-member 23 and supported by an adjustable castor 22. The wheel hub 20 is connected to the rim 26 by spokes 25 and to a disc 28 on the axle by rods 27. The leg 34 of each tine is mounted on a coil-spring 32 on the rim and is attached to the foot 39 through an eyelet 35 engaging a loop 38 in the foot, which extends inwardly to form a guide-member 36 passing through an aperture in the disc 28 ; the guide 36 is cranked at 37 to prevent its removal from the aperture. Projections 29 extend forwardly from the rim 26. In Fig. 4 two types of tine are shown, each type having a spoke-portion 45 or 59 within the rim and being bent twice outside the rim to form the legs 48, 62 and the feet 49, 62 respectively, the second bend being a loop 50, 64 through which is passed an undulating endless wire 51, 65. In the type shown in the upper half of the Figure, the spokes pass through non-collinear apertures in three concentric members 58, 57, 44 the members being united by spokes 56, and the inner ends 61 of the spokes are bent-over inside the innermost member 58 so that the tines can turn about their spokeportions. In the type shown in the lower part of Fig. 4, the tines are made in pairs having bends secured to a disc 43 by bolts 46, the portions 45 between the bolts and the rim 44 constituting spokes which support the rim. In Fig. 9, the tines 83, 84, 85 are similar to the last type shown but the rim 82 is preceded by a second rim 86 through which spokes 88 protrude to form short tines 87, both rims being carried by a disc 81 on the hub 80. Specification 802.363 and 802,365 are referred to.
