Abstract: 692,403. Variable-pitch propellers. LIAAEN, N. J. Nov. 16, 1951. [Nov. 16, 1950] No. 27005/51. Class 114. In a variable-pitch marine propeller in which the propeller hub is lubricated by oil supplied thereto under pressure which also acts to reduce the ingress of sea water, the intake of the return flow passage 7 for the oil is located at or near the wall of the hub where the distance of the wall from the axis of the hub is a maximum. Any sea water which may enter the hub will thus be removed therefrom by centrifugal action. The oil is supplied to the hub from a reservoir 17 by a pump 16 through passages 25, 29, 30, 31, 33, and the annular space between a tube 20 and a pitchchange rod 4. The oil is returned through passage 7, an annular passage 5<SP>1</SP> surrounding the tube 20, and passages 21, 22, 17<SP>1</SP>. The blades are adjusted through the rod 4 by a servomotor piston 45. The propeller shaft bearing liners 10, 11 are supplied with lubricant from a tank 35. In another embodiment the tube 20 is omitted and the return passages are provided by axial passages or grooves in the bearing liners. A tank is also inserted in the return line for separating out any sea water which may be present in the oil. Alternatively, the oil may be conveyed to or from the hub through a bore in the rod 4.

The spraying apparatus which is the subject of Specification 993,277 is applied to inlet gases to a dust collector in a dry type of rotary cement oven. The conductivity of the gases admitted to the dust collector is regulated within optimum limits by feeding a minimum quantity of water in a spray the droplet size of which ensures that none of the water reaches the walls of the inlet humidifying chamber before evaporation. A shown in Fig. 2, exhaust gases from the oven pass into a humidifying chamber with spray nozzles 9 fed with water and compressed air. Precipitation in the humidifying chamber is collected in hoppers 17 and evacuated by screw 18. Deposit on the walls of the chamber and hoppers is removed by shock vibrators 16. Such a vibrator may also be attached to the nozzles. The humidifying chamber may be vertical with a downflow of gases.

Abstract: 709,268. Brake control systems. BRITISH THOMSON-HOUSTON CO., Ltd., and SIMONS, D. S. Nov. 7, 1951 [Nov. 7, 1950], No. 27209/50. Class 103(1) [Also in Group XXXVII] In a brake system of the kind described in Specification 461,444, [Group XXXVII], wherein the weight W or spring acting upon a brake lever arm F is opposed by an electro hydraulic device T so arranged that the brakes are automatically applied upon failure of the power unit of the electro hydraulic device, the power is so controlled that there is a linear relation between the braking torque and the degree of control action applied. As shown in Fig. 1, the brake lever F has an applying weight W which is raised to release the brake by one or more hydraulic thrusfors T. A control circuit for operating two such thrustors, T 1 , T 2 , which may be designed to give the desired relation between control lever movement and braking torque is shown in Fig. 2. The two thrustors T 1 , T 2  are connected in series with a source of constant potential and also with the second device S of a twin unit induction regulator R. By restricting the movement of the control lever, which adjusts the induction regulator, to 83 per cent of the full range, a linear control of voltage with lever movement may be obtained. Alternative methods of control suggested are a saturable reactor unit or a three phase potentiometer or rheostat. Reference is made to the brake system described in Specification 268,621, [Class 103(i)].

Abstract: 483,019. Centrifugal switches. HOOVER HOLDING CO., Ltd. (Conley, B. L.) Oct. 9, 1936, No. 27430. [Class 38 (v)] In a centrifugal switch each weight G is carried on a pin F2 which also serves as the pivotal connection between two arms F, G<1> ; the other end of the arm F pivots about a fixed point E<3> and the other end of the arm Gl is pivoted to a member H<1> forming part of a sleeve H slidable on the shaft. The arrangement is such that the weights swing outwards with increasing speed, even though the speed of rotation of the shaft does not increase, and the contacts are opened with a rapid and certain action. The axial force on the sleeve H first increases and then decreases as the weights fly outwardly. The pivot pins E<3> form part of a frame E fixed to the shaft A. Springs G2 tend to hold the weights in the position shown, but when the speed reaches a certain value the weights fly out and move the sleeve to the right. In the form shown, a spring J<1> is arranged between the member H<1> and a loosely-mounted collar J which is normally pressed by the spring against the contact arm D<1> holding this in engagement with a fixed contact C. The members D<1>, C are mounted on a stationary part A<1>. When the sleeve H moves to the right, the spring J<1> expands till a rim H<2> on the sleeve engages the collar J and moves this rapidly to the right and allowing the contact arm D<1> to move away from the contact C. In a modification, Figs. 8-11 (not shown), the sleeve H has fixed to it a collar J which presses against a disc connected by springs and with lost.motion to the contact arm.

Abstract: 533,534. Lubricating fittings made of phenol formaldehyde resins. BENDIX, Ltd., and IRVING, J. S. Oct. 9, 1939, No. 27487. [Class 2 (iii)] [Also in Group XXIV] A lubricating fitting for the conduit of a flexible cable comprises a fitting made of a plastic moulding material, such as a phenol-formaldehyde condensation product, moulded directly on to the conduit. In moulding the fitting a on to the conduit b, the material is forced into the helical groove c formed between the convolutions of the flanged strip from which the conduit is made, thus effectively keying the fitting to the conduit. A circular boss d on the upper part of the fitting has an annular upstanding wall e around an annular recess f in the centre of which is a nipple-like projection gadapted to receive a grease gun or the like. A hole is drilled in the conduit opposite the bore h. In a modification, the nipple g instead of being integral with the body a, is a separate member of metal moulded into the fitting. Where a number of conduits require lubricants of different types or grades, the fittings moulded on these conduits may be of plastic moulding materials of different colours corresponding to the grade of lubricant.
