IPC: C21C7/00
Filed: 1935-06-20
Abstract: In a process for controlling regularly the grain size of steel or alloy steels, the slag covering a bath of molten steel &c. is removed, a protective synthetic slag poor in iron oxide immediately added to the bath to cover the same, one or more deoxidizing agents being or having been added to the ball in one or more stages and then causing to act on the steel &c. such an amount, which is predetermined by control tests made with steel &c. of the same analysis produced by the same process and under the same conditions which in the limiting case may be zero, of a substance such as aluminium, titanium or vanadium which has a strong influence on grain size, that the desired grain size is regularly obtained.  The deoxizing agents may comprise silicon or manganese or alloys of these elements in the solid or liquid state and may be added to the bath after the initial slag has been separated therefrom and before the protective slag is added.  The protective slag may be brought into contact with the bath by the methods described in Specifications 404,300, 405,456, 405,633, 423,584, 423,731, and 423,732.  The grain influencing substances may be added in the pure state or in the form of alloys containing one or more of these elements in known quantity as well as if desired other ingredients such as silicon manganese and iron.  The protective slag or its elements may be charged in the solid state in the bath and are easily fusible so that they rapidly cover the bath with a layer of liquid slag.  The grain-influencing substance may be introduced into the molten steel &c. after the latter has been poured into the ingot moulds. The treatment of a particular low carbon steel, a mild nickel-chromium steel, a mild nickel steel, and a chromium molybdenum steel is referred to. Specifications 408,253 and 436,450 also are referred to.

Title: Improvements in or relating to travelling wave tubes
Inventor: ROGERS DOUGLAS CECIL
IPC: H01J23/065
Filed: 1954-06-21
Abstract: 787,181. Travelling wave tubes. STANDARD TELEPHONES & CABLES, Ltd. June 17, 1955 [June 21,1954], No. 18181/54. Class 39(1). In a travelling wave tube provided with noise reducing means comprising at least two successive accelerating gaps in the gun followed by a field free " drift tube " connected between the final anode and helix, the magnetic focusing field is made divergent in the gun region so as to reduce the noise space charge waves still further. The divergent magnetic field is obtained by reversing the position of the magnetic pole piece 28 so that it projects forwardly instead of backwardly from the magnetic end plate 16, and the cathode is placed inside the pole piece tunnel one inch from the left hand end. The axial field is zero in the plane of the end plate due to the shielding effect of the pole piece and increases to a maximum at the right hand end of the pole piece tunnel, thereafter decreasing to a constant value along the helix. The magnetic field will therefore diverge from behind the cathode and become parallel at the right hand end of the pole piece. Alternatively the current in the first solenoid coil 17 can be made greater than in the remaining coils. The accelerating gaps are formed between cathode and anodes C, A 1 , A 2 , A 3 , Fig. 1, at D.C. potentials of 0, 55, 115 and 950 volts respectively, anode As being connected to one end of drift tube 7 which is of such length that its end adjacent the helix is a point of A.C. noise velocity minimum. 3 is a cathode shield electrode. The spacing between A 1  and A 2  is twice that between the cathode and A 1  but equal to the spacing between A 2  and A 3 . The probe 9, connected between " drift tube " 7 and helix 8, and about one turn of the helix, lie within input wave-guide 10. Focusing coils 17- 22 are clamped by tie bars 23 of magnetic material between magnetic end plates 14, 16. The magnetic field may vary from 600 gauss ¢ inch behind the cathode to 320-330 gauss 3 inches in front of the cathode, and the spacings of A1, A2 and A3 from the cathode are respectively 0À053 inch, 0À170 inch and 0À320 inch. A prior art arrangement is referred to in which the gun has two accelerating gaps to reduce noise as in the present invention but in which the magnetic field is uniform ; the potentials of the gun electrodes and beam current may be so adjusted that the beam diverges between the cathode and first anode, and this is stated to further reduce the noise by 2dB.

Title: Light pencils
IPC: G06K19/06
Filed: 1974-04-25
Abstract: 1428932 Light pens NIXDORF COMPUTER AG 25 April 1974 [25 April 1973] 18184/74 Heading G1A The sensing tip of a light pen is constituted by the end of a spring-biased light conducting element coupled by two lengths of flexible light conductor to a source and a detector mounted in the pen. As shown, Fig. 2, the pen comprises a body member 10 on which is detachably mounted a front cap 2. A light conductor comprising a glass rod 19 protected by a metal sleeve 18 is slidably mounted in the cap 2 with the tip 16 of rod 19 projecting. A recess 21 in the sleeve 18 receives a coupling member 20 mounted on the end of a tube 22 the rearward end of which forms a head 48 carrying two plates 50, 52 providing mountings for a light source 44 and a detector 46. Optical fibres 36, 38 extend from the source and detector to the coupling member 20, within which they are embedded and extend to the centre of the forward face which is ground and polished to provide a good optical coupling to rod 19. The tube 22 and the head assembly are slidably mounted within the pen and are biased towards the tip by a spring 24. The source and detector are coupled to a signal handling circuit by flexible cables 62, 4, 6, 8. A tab 60 bent down at the end of a sleeve 13 lining the body 10 forms a stop to limit the forward movement of the sliding assembly, a suitable recess being provided in the head 48 to allow rearward movement. Excessive pressure applied to tip 16 overcomes the spring bias allowing the tip to retract within the cap 2 where it is protected from damage. If the tip 16 is damaged the cap 2 can be removed and a replacement light conducting rod and sleeve unit inserted. An image conductor or an optical fibre cone may be used in place of glass rod 19. The pen may include a translucent or transparent ring 28 which can be selectively illuminated by lamps 32 to provide a signal from the processing circuitry to the operator as in Specification 1420726.

Abstract: 516,432. Wire strainers. GREBERT, E. C. L. June 21. 1938, No. 18454. [Class 45] [Also in Group XVII] A machine for binding packages with metal ties comprises means for feeding. the binding material so that it can be passed around the package and means for clamping the forward end of the material and 'for reversing the feed so as to tighten the tie. The binding strip F is. fed from a reel 1 by rollers 2, 3. 4 which may be driven in either direction by pulleys 5, 6 alternatively coupled to a driving shaft 22 by clutches 23, 26 and 24, 27. In operation, a pedal 34 is depressed to start the feed by engaging the clutch 23, 26 and the leading end of the strip is taken through the slot A in the table, around the package and between an anvil 7 and sliding bolt 8. The pedal is released, and the bolt is moved to clamp the tie by a handle 9, which also by means of a lever 37 shifts a link 33 along a slot 36 so that further depression of the pedal 34 engages the clutch 24, 27 to reverse the feed and tighten the tie. The axes of the rollers 4, 3 are disposed in a horizontal-slot 54 and a vertical slot 55 respectively to enable a strong pull to be obtained. The actuation of a handle 42 withdraws a stop 43 to release a spring-controlled pawl 59 carried by a crank plate 44 loose on the shaft 22, so that a boss 56 on the pawl falls into a notch 58 and clutches the crank plate to the shaft for one revolution until the pawl again strikes the stop 43. A sliding cam 45 which is thereby reciprocated lifts a pair of clamps 14, 17 which hold the sealing strip S and the binding strip F while knives 15, 16 operate to cut the strips. The length thus cut from the sealing strip is lifted and pressed around the overflapping ends of the tie by a pair of sliding members operated by the continued movement of the cam 45. The return of the cam 45 controls a pawl 52 to feed forward the sealing strip S in readiness for the next sealing operation. As the crank plate completes its rotation, a cam 41 strikes the lever 37 and returns the link 33 to its normal position.
