Abstract: 1504626 Continuous casting VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE-ALPINE MONTAN AG 2 May 1975 [12 June 1974] 18595/75 Heading B3F [Also in Division F2] A variable-throw crank in a reciprocating drive for moulds in continuous casting plants is steplessly adjustable to infinitely variably adjust the reciprocating stroke of a rod 6, Fig. 1, connected between the crank-pin 18, Fig. 2, and one end of a beam structure 8, 8<SP>1</SP>, which beam structure 8, 8<SP>1</SP>, is pivoted at 9, 10 and is connected at its other end to a suspension member 11 of a continuous casting mould (not shown) for variable-stroke reciprocating movement thereof. As shown, a motor 1 drives through an infinitely-variable reducing gear 2 (for varying the stroke frequency of crank-pin 18) and coupling 3 to a pinion 13, Fig. 2, which meshes a toothed wheel 14 in a common housing 12. The toothed wheel 14 is rotatable on its axis 25 and carries, journalled therein, a crank-shaft 16 rotatable on an axis 26 spaced from and parallel with axis 25, the crank-shaft 16 having a crank arm 17 formed with the crank-pin 18 the throw of which from the crank-shaft 16 is equal to the distance between the axes 25, 26. The crank-shaft 16 is integrally formed with a helically-toothed segment 19 which meshes with a further helically-toothed segment 27 axially slidably mounted on a guide pin 23 fixed in the toothed wheel 14 with its axis 24 parallel to axes 25, 26. The segment 27 is connected to a plate 22 which via a pin 28 is journalled at 29 in a bell housing 30 connected to an axially movable spindle 31, this unit forming the crank-throw adjuster unit that is driven by a motor 5 or by hand. In operation, downward movement of the spindle 31 downwardly moves the helicallytoothed segment 27 which via its teeth turns the helically-toothed segment 19 to turn the crank arm 17 and hence move the crank-pin 18 from a position shown in full in Fig. 3, in which the stroke amplitude is zero, to the position shown chain-dotted therein wherein the stroke amplitude is h, the amplitude being steplessly variable as the crank-pin 18 moves from its zero stroke position. In any stroke-adjusted position, the frequency of stroke is steplessly controlled by the steplessly variable drive 2.

Title: Improvements in and relating to the manufacture of straw pulp
IPC: D21C5/00
Filed: 1948-07-13
Abstract: Straw from barley, wheat, rye and oats, &c. is shredded longitudinally into fine strands, chemically treated at about 100 DEG C., e.g. for 8 to 12 hours, and agitated to produce high-quality pulp.  The straw is shredded preferably in a moist condition, containing, e.g. 20 per cent by weight of water.  The shreds may first be soaked with an aqueous solution or fine suspension of the chemical and then cooked by applying low-pressure steam for 3-5 hours.  The pulp may be washed with water before being agitated.  The chemical may be an alkali such as caustic soda, lime, sodium carbonate, potassium carbonate or mixture thereof or sodium sulphite, bisulphite or sulphide.  A solution containing 1000-1300 gallons water and 200-250 lb. caustic soda or 150 lb. caustic soda and 100 lb. lime may be used for each ton of straw. The straw may be shredded into strands not more than 2 inches long in a machine having two or more rotatable spiked drums surrounded by a casing carrying spikes which intermesh with those on the drums.  The pulp may be agitated in a similar machine having only one drum.  The Provisional Specification also describes kneading of the pulp in a machine having two longitudinally-channelled rollers which mesh loosely and are mounted in a helically-ribbed casing.

G.; 306, Cooper Street, Camden, New Jersey, U.S.A.) July 2, 1935, No. 18948. Convention date, July 2, 1934. [Classes 39 (i) and 40 (v)] In a transmitter, receiver, or oscillator system for microwaves down to wavelengths of a few mm., the electron discharge device has a split anode system formed by opposite end faces 31, Fig. 1, of a segment of a metal ring 17 forming a short resonant path. The filament 7 is supported between the faces 31 from a pinch 9 and the ring 17 is supported by spaced parallel leads 4. A magnetic field is applied along the filament 7 ; the field is at a slight angle to the filament 7 unless plates which may be biassed are arranged at the ends of the discharge space bounded by the faces 31. An antenna 5 is mounted outside the envelope 1 or inside a pear-shaped enlargement at the top of the envelope and is connected to the anode supply 12 through a choke 14 and a transformer T used for modulation in a transmitter and for the output of demodulated signal in a detector. The Specification as open to inspection under Sect. 91 comprises also a Barkhausen- Kurz oscillator, Fig. 1 (Cancelled), with a positive grid 35 receiving modulating signals from a transformer T and with a split plate 3 maintained at a low potential through parallel leads 4, an antenna 5 and a choke 14. A bar 6 is welded across the leads 4 close to the plate 3 to form a resonant loop determining the oscillation frequency. The electrode system may be provided with end plates. In a modified magnetron, the halves of a dipole antenna extend in opposite directions from the halves of the anode and are connected to the anode supply through halves of a choke within the envelope. In another modification, the coil supplying the magnetic field surrounds a cylindrical part of the envelope and the electrode system is axially arranged in this part. The antenna may be inside or outside the bulb in all modifications. This subject-matter does not appear in the Specification as accepted.
