Filed: 1931-05-06
Abstract: 368,135. Reversing-gear for boats. PORTER, F., Sandridge Works, Whetstone, London. May 6, 1931, No. 13354. [Class 114.] Reversing-gearing for motor-boat propulsion is controlled by a lever 19 which is pushed forward and aft to effect ahead and astern driving, respectively. The lever 19 is connected by a rod 14 to a cam quadrant 21 which disconnects the engine clutch 29 while a double dog clutch 10 is being shifted. A striker 12 for the clutch 10 is slidably carried on the rod 14 between two springs 15. The clutch 10 slides on a square part of a propeller shaft 1 and is moved forward to effect a direct drive from a clutch shaft-2. A countershaft 5 is connected by a spur pair 3, 4 to the shaft 2 and by a chain 7 to a sprocket 8 loose on the shaft 1. When clutch 10 is shifted aft, a reversed drive is effected through the gearing. This reversing- gear can be readily obtained by modifying a conventional vehicle gear-box. The clutch 10 preferably carries a disc 33 which can be braked when passing through neutral to facilitate dogclutch engagement. A brake 32 may be a fixed device engaged by the disc as it passes, or a band applied by the striker 12 in transition. A modified form of reverse gear is described in which the drive is taken from the parallel shaft 5 which carries the double clutch slidable between loose spur and chain gears 4, 6. The aligned shaft 1 is in that case secured permanently to the main clutch shaft 2.

IPC: A01B3/54
Abstract: 134,561. Wade, H., (Berliner Akt.-Ges. f³r Eisengiesserei und Maschinen-Fabrikation). Nov. 12, 1917. Ploughs.-Relates to motor.ploughs having a separate frame carrying the shares, and consists in means for automatically raising and lowering the share frame in ending and starting a furrow. The shares are carried by a triangular frame 14, 15, 16 having a roller 7 at each corner adapted to run in curved guide-brackets 6. A rod 9 fitted with a spring 8 is connected to the frame bar 14, and the spring is so arranged that, when the shares are out of work, it draws the rollers 7 up the curved guides 6 into the position shown at 7<1>, in which the shares are raised clear of the ground. When the leading furrow-wheel and driving-wheel 3 enter a furrow, the points of the shares come in contact with the ground, and the resistance thus encountered draws the frame backwards against the action of the spring 8, and the rollers 7 ride down the guide-brackets 6 into the position shown in Fig. 1, in which the shares are lowered into work. The reverse action takes place when the furrow-wheel and wheel 3 ride out of the furrow at the headland. The land-wheel 2 and furrowwheel 1 are independently adjustable vertically by means of screwed standards to regulate the depth of the ploughing.

Title: Improvements in or relating to porous metal bearing composition
IPC: F16C33/12
Filed: 1937-05-13
Abstract: In making porous metal bodies for bearing bushes, packing-rings, and the like by compressing and sintering spongy iron particles, the pressure may be exerted by filling into a hollow flexible cover which is exposed to hydraulic pressure. ALSO:Porous metal bodies for bearing bushes, packing-rings, and the like are made by compressing and sintering spongy iron particles of a size and porosity corresponding in a loosely poured state to a specific gravity of 1-1,5, without admixture of a bonding metal, the specific gravity of the pressed and sintered product being 4,5-5,5.  The size of the original particles may be 1/20 -3 mm., and they may be obtained by disintegrating spongy iron ingots by cutting or tearing without crushing.  The spongy iron may be produced from iron ore or by the reduction of waste iron oxide by means of a reducing gas, the reduced iron particles being sintered together under the action of their own weight.  The pressure may be exerted from several directions, e.g. by means of upper and lower punches moving into a die from opposite directions; or the particles may be filled into a hollow flexible cover which is exposed to hydraulic pressure.  Sintering may be effected at 1200 DEG  C. in a reducing or non-oxidizing atmosphere for up to 2 hours.  Pores on those parts of the surfaces not exposed to friction may be closed by solder, tin, copper oxide, powdered copper, metal precipitated from a salt solution, or artificial resin or other varnishes.

Class 39(iii) In furnaces having graphite electrodes traversing the furnace walls below the surface of the molten mass, a portion of each electrode is received as a close sliding fit in a member extending at least part way through the furnace wall from the outside, that portion of the member that is in contact with the electrode being wholly constituted of material having a coefficient of expansion close to that of graphite and a low coefficient of friction in relation to graphite. In Fig. 1, the member is a sleeve 4 surrounded by a casing or deposit 6 of metal or other material impermeable to air, such as silicates of high melting point. A cooling gas is passed through a box 7 surrounding the sheath 6. In Fig. 2, gaseous jets from a box 7 surrounding the electrode 3 cool the end of the sleeve 4. The sleeve 4 may be of carbon and, in particular, of graphite and is axially displaceable as is also the electrode 3. The sleeve 4 prevents air from contacting that region of the electrode which reaches a temperature at which the carbon or graphite will burn in air. The cooling means may be regulated such that the molten mass 2 contacting the sleeve 4 remains in a fluid condtion. The molten mass 2 may be glass.
Patent GB-601127-A (GB)
Title: Improvements in or relating to misalignment indicators for continuous following systems
IPC: G01S3/42
Filed: 1945-05-31
Abstract: 601,127. Cathode-ray oscillogaphs. TOMLIN, D. H., and OXFORD, A. J. H. May 3], 1945, No. 13748. [Class 37] [Also in Group XL (c)] Relates to means for measuring the relative amplitude of two signals on a cathode-ray oscilloscope. According to the invention, the oscilloscope beam is deflected in one direction according to the difference of the two signals and in a transverse direction under the control of a sweep voltage initiated by the mean signal so that the existence of signals is indicated by a line trace and the difference in signal amplitude by the lateral displacement of the line trace. The invention is described as applied to a radio direction-finding system (see Group XL (c)) in which the signals are those received by the overlapping lobes of the receiver aerial system and the signals applied to the oscilloscope are in the form of substantially D.C. voltages. As shown in Fig. 1, the two D.C. voltages are applied to terminals 1 and 2 and thence to the X plates of a cathode-ray tube and a voltage proportional to the mean of the D.C. voltages is applied to charge condenser C1. through a diode V1 which is shunted by the high resistance R5 so that the discharge time of C1 is high and the condenser voltage is not greatly affected by momentary interruptions of the signal. When the voltage across C1 is above a predetermined value, it unblocks the valve V2 and the 50 c/s. mains voltage which is applied to the suppressor grid then appears at the anode and is applied to the Y plates through a transformer T. The luminous spot on the oscilloscope screen is thus drawn out into a vertical line which is displaced horizontally from a central marked position by an amount proportional to the difference of the two signals. The bias potentiometer P3 is adjusted so that the length of the trace increases rapidly and thus remains substantially constant with increasing signal strength. In a modification, Fig. 1A, greater sensitivity is obtained by applying the two D.C. voltages to the deflecting plates X1, Y1 and X2, Y2 and the A.C. voltage to the transformer T such that the A.C. voltages applied to plates X1 and Y2 are of the same potential and opposite polarity to the A.C. voltages applied to the plates X2 and Y1. In a further modification, Fig. 2 (not shown), the condenser C1 is connected to the control grid of a transitron oscillator with a feed-back condenser connected between anode and control grid so that linear saw-tooth voltages are produced when a positive voltage is developed across C1 and these saw-tooth voltages are applied to produce the vertical line on the oscillograph screen.
