Title: A propelling rudder
IPC: B63H25/38
Filed: 1923-01-18
Abstract: 212,037. Moss, B. Jan. 18, 1923. Propelling by vibrating rudders.-Relates to vibrating propelling blades carried by ships rudders such blades being spring controlled and adapted to be locked to the rudder frame. The blade 1 is supported in sockets 2 in the upper and lower arms 3, 4 of the rudder frames Two quadrants are carried by a pivot pin 6 on the blade and are locked bv a thumb screw 8. When the blade is to act as a rudder it is positioned as in Fig. 1, the part 7 of the quadrants being moved up into a slot in the arm 3 to lock the blade to the frame. When used as a propeller, the quadrant is freed from the frame, the blade is turned through 180‹ in its sockets to the position shown in Fig. 2, movement of the blade relative to the frame being limited by two springs 11 carried by the quadrants. Instead of reversing the blade it may be permanently carried on sockets placed one-third the width from the forward edge and oscillation of the blade may be produced separately from movement of the rudder stock. In one form the spindle for producing oscillations is coupled to locking clips pivoted on the rudder frame which are moved out of engagement with the blade by an upward movement of the spindle. In a modification, the blade is divided into two parts, a forward portion which is hinged to the rudder frame and is under spring constraint, and an after portion mounted on pivots. For use as the rudder the two parts are locked together and to the frames by side plates. For propulsion the whole frame is rocked on the supporting pins by ropes attached to a yoke on the rudder head.

Title: Improvements in or relating to the assessing of surface profiles
Inventor: STARR ARTHUR TISSO
IPC: G01B7/34
Filed: 1965-01-18
Abstract: 1,129,962. Evaluating surface roughness; photo-electric graph reading. RANK ORGANISATION Ltd. Jan.18, 1966 [Jan. 18,1965; Aug.26, 1965], Nos.2166/65and36673/65. Headings G1A and G1N. The surface roughness of a machined material is measured and analysed electrically to determine the average roughness. As shown (Fig. 6), the surface is scanned by a stylus A driven across the test surface by a motor M1 through rack and pinion 4a. The output from a transducer B is fed to a galvanometer 10, whose mirror 11 reflects the light from a lamp 12 on to a film strip 3 for recording the tracer signal. The film record, comprising a contour line separating dark and clear areas, is fixed in a tank 8, and assessed at station 9, light from lamp 12 is fed through that portion of the strip located between sprockets 5a and 18, firstly to a photo-cell 17, giving a signal corresponding to the original gauge signal, and so to a number of individual photo-cells 16, the light passing through a number of lenses 15 and a light filter 15a whose opacity varies along its length in accordance with a predetermined weighting function (Fig. 8) which is symmetrical about the value measured by photo-cell 17 and with alternating positive and negative parts of diminishing amplitude. The outputs from cells 16, some of which are negative, are algebraically added to determine the mean value, which may be added to the record on strip 3. The two signals may also be combined to estimate the roughness as the deviation from the mean value. In a modification, the weighting filter 15a is replaced by electrical weighting of the output of the photo-cell 16. The tracer output may be recorded on a magnetic tape, and the photo-cells replaced by reproducing heads in association with weighted electrical circuits. In another embodiment (Fig. 15), a lamp 51 produces a slit of light across a moving belt 50 through a transparent electrode 55 fed with the gauge signal. The belt 50 is coated with a photoconductive material which is charged by the light to a voltage determined by the signal voltage on electrode 55, located downstream along the belt are capacitor electrodes 56, 57, 58 shaped in accordance with the desired weighting function, which sum the surface charge over its areas, and add the pick-up voltages algebraically to give an output signal voltage which is the required mean value. The corresponding mid-ordinate value is measured by a narrow strip electrode 59. The mean value may be obtained by feeding the gauge signal through an integrating delay network whose characteristic incorporates the weighting function.

Abstract: 452,507. Thermionic cathodes. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, GABOR, D., 30, Falk Miksa ucca, Budapest, and FAIRBROTHER, J. A. V., 110, Eastlands Road, Rugby. Jan. 23, 1935, No. 2238. [Class 39 (i)] [See also Group X] A method of making good thermal contact between a metal surface and a surface composed of ceramic material such as magnesia or alumina, for use for example as an electrode for an electric discharge device, consists in providing a layer of metal powder mixed with a volatile binder between the two surfaces, pressing the surfaces together to fill any spaces between them, and finally heating to drive out the binder. In an example, a thin flat nickel disc coated on its upper side with electron-emissive material is attached to a ceramic disc-shaped body containing a heating-element by painting or coating the ceramic body with a layer consisting of powdered nickel or tungsten mixed with cellulose nitrate dissolved in amyl acetate, the metal disc being pressed into close contact with the coated surface and the whole then heated to reduce the binding-layer to pure nickel or tungsten. Alternatively, a metal oxide such as nickel oxide may be mixed with a volatile binder and pressed between the surfaces, after which they are heated in a hydrogen reducing-furnace to reduce the oxide mixture to metal.
