Title: Engraving- and copying machine
IPC: B44B3/00
Filed: 1951-01-30
Abstract: 683,737. Copy-milling. DECKEL, H., and DECKEL, F. W. Jan. 30, 1951 [Feb. 9, 1950], No. 2300/51. Class 83 (iii). An engraving and copying machine comprises a slide 24 which carries a tool spindle 34 and a copying stylus 32 and is mounted on a bar 20 to be movable in two directions parallel to the planes of work and pattern tables 38, 48, the bar 20 being movable with the slide 24 also in two directions transverse to the sliding direction of the slide and parallel to the said planes. The machine is characterised by means 37 removably attached to the machine and co-operating with the slide or the bar to prevent its movement, or to prevent its movement beyond a position intermediate of its extreme positions, in at least one of the directions of movement parallel to the plane of the tables. The bar 20 is supported by a parallelogram linkage 16, 18 on a vertically movable slide 14. The cutter is belt-driven by a motor (not shown). The work 44 and pattern 46 are carried respectively by the tables 38, 48 rigidly linked at 50, 52. The table 38 is adjusted by nut and screw mechanisms actuated either by handles 56, 58 or by ratchet levers 72. In operation, the slide 38, and with it the slide 48, are adjusted by known means to the correct height and the cutter and work positioned to cut a line " a." The linkage 16, 18, the weight of which may if desired be counterbalanced in known manner, is then locked by the link 37. The ratchet device 72 for the screw 62 is set by a graduated dial to give the required advance, i.e. the distance between successive lines " a," " b," &c. and the cutter is then rotated while the slide 24 is reciprocated. The work and pattern are advanced after each line has been cut, the total advance being indicated by a second graduated dial. Should undue resistance be encountered in the movement of the slide, a spring clutch, between the slide and its feedscrew, slips. In a modification, the link 37 may be attached to the members 20, 14 or may be in the form of an adjustable abutment 166, Fig. 6. Movement may, alternatively, be prevented in a direction at right-angles to the previous examples by a rail 168, Fig. 7, contacted by a roller 170 attached to the toolholder. If the pattern and work-tables are not linked together, separate feeding means are provided for each slide.

Title: New catalyst of high mechanical strength
IPC: B01J37/00
Filed: 1937-01-28
Abstract: Catalysts of high mechanical strength are obtained by forming into pieces a catalytic compound under a pressure of at least 500 atmospheres, and subsequently heating the material to a temperature of at least 850 DEG  C., preferably at least 920 DEG  C., the said temperature being substantially below the melting-point of the material.  The product may be crushed and again compressed and heated as before, and may finally be reduced if desired.  The material may consist of a mixture of substances which react during the heating to produce a compound having a melting-point above the temperature employed.  Suitable mixtures consist of basic oxides and difficultly reducible acidic or amphoteric oxides, e.g. a mixture of an alkali or alkaline earth oxide with an oxide of a metal of groups 3 to 8, or a mixture of an iron group metal or compound thereof with one or more of the oxides of aluminium, magnesium, chromium, tungsten, silicon, and uranium with a small addition of boric or phosphoric acid. According to a typical example a mixture of nickel nitrate and magnesium oxide with a little boric acid is dried, ignited, and screened, and is then compressed into tablets under a pressure of 700 kg. per sq. cm. The tablets are heated to 920-1090 DEG  C. for 36 hours, and then reduced in hydrogen.  Other examples relate to mixtures of chromium oxide with alumina or magnesia.  Catalysts according to the invention are suitable for the dehydrogenation of hydrocarbons, the destructive hydrogenation of carbonaceous materials, and the syntheses of methanol and of liquid hydrocarbons from oxides of carbon and hydrogen.

Abstract: 717,343. Stabilizing and steering ships DOULGHURIDIS, A. M. Feb. 4, 1952 [Feb. 10, 1951], No. 2899/52. Classes 113(1) and 114 The rolling of a ship is neutralized by creating uninterruptedly on board a strong fluid current or stream and directing said stream in the direction of roll of the ship against the ambient medium, the direction of the current being automatically and instantaneously changed with every change in direction of roll thereby setting up a reaction force in a direction opposite to that of the roll, the intensity of the reaction force being varied automatically proportionately to the amplitude of the roll by a pendulum device (Fig. 4) having a series of electric contacts 24 having retarded interruption, the intensity of the reaction force remaining the same during the whole of the roll of the ship in one direction. In the embodiment of Fig. 1 the current is produced by a propeller 7 on a mast 2. When the ship rolls the mast traces the arc 3-4 and viceversa, the change in direction of the current is obtained by reversing the pitch of the propeller blades. In the embodiment of Fig. 2 the current is directed through a tube 8 and out of one or other of the opposed discharge ducts 8a, 8b, dependent upon the position of the valve 8c. In the embodiment of Fig. 2a a rotary tube 8e has its upper end laterally curved, the change in direction of the current being obtained by half rotations of the tube, which rotations are made towards the stern so that the forward movement of the ship is not impeded. If two of the above described devices are placed at each end of the ship. one directing current to the left and the other to the right, they can be used to turn the ship. In another embodiment the current reacts below the water line.

Patent GB-574354-A (GB)
Title: Method of forming sheets and articles of glass or other thermoplastic material or metal
IPC: C03B11/08
Filed: 1943-03-01
Abstract: <PICT:0574354/IV/1> A smooth surface is formed upon a mass of heated plastic material by vibrating towards and from the material a solid cool surface, the frequency of the vibrations being so great that the plastic material cannot follow them and a thin gaseous layer being admitted or interposed between the solid surface and the plastic material.  Fig. 1 shows apparatus for casting a sheet of glass on a smooth polished metal table 14, the glass being initially sheeted by rollers 12, 13.  The table is supported on flexible members 18 and is vibrated, through an amplitude of a few thousandths of an inch, by a solenoid 16, which may be connected to a frequency-changing apparatus.  The direction of vibration has a component towards the left, whereby the sheet is urged to the left, and a vertical component.  The speed of descent of the table is greater than the speed at which the glass will follow it under the influence of gravity, the result being that air is sucked in between <PICT:0574354/IV/2> the table and the glass and the sheet is supported on a film of air which is alternately compressed and expanded.  The finish of the glass is thus like that of a surface hardened in contact with air only.  Jets of air may be introduced between the table and the sheet, to compensate for air ejected, the table being grooved for this purpose.  The table is in three hollow sections 14a, 14b, 14c through which sections cooling medium may be passed.  Air nozzles 24 cool the upper surface of the sheet.  The rollers 12, 13 may be replaced by two sheeting rollers which act successively on the mass, or by a vibrating presser foot.  Fig. 6 shows an apparatus for forming lenses, a gob of glass G being held in shape, while it cools, by air trapped between it and two mating dies 30, 32 which are vibrated by solenoids 34, 36.

Abstract: 556,124. Shock-absorbers. LUCAS, Ltd., J., and DOUGLAS, P.March 17,1942, No. 3526. [Class 108 (iii)] In the hydraulic shock absorber of the sliding piston type used on road vehicles, means is provided whereby on each action stroke the piston meets relatively low resistance within a predetermined range and the full normal resistance only when that range of stroke is exceeded. In the double piston opposed construction shown in Fig. 1, in which the two main pistons a are reciprocated together by the arm e, the outer end of each piston forms a cylinder in which works a sub-piston k, the movement of which is limited by a shoulder at one end and a spring ring m at the other. A one way-valve h with a throttling orifice q ensure free return of the main piston. After the play of the sub-piston is taken up, main piston movement is resisted by throttling passages r, s with pin t while excessive resistance exerted through passage q lifts spring plate p. A spring may resist movement of the sub-piston. A plate with valves similar to the sub-piston may be arranged at the rivet end of the cylindrical recess to provide hydraulic resistance to the movement of the sub-piston. In a modification two parallel main pistons each with its sub-piston are each forced by spring into contact with a twoarm operating lever. A single main piston with subpiston may be used.
