Filed: 1964-05-26
Abstract: 997,941. Paper-making. ESCHER WYSS G.m.b.H. July 11, 1961 [July 14, 1960], No. 25084/61. Heading D2A. [Also in Division B2] Fibrous material, particularly for paper making, is treated by passing it between two discs which rotate relatively to one another. Each disc has concentrically spaced rings of teeth, with the tooth-rings of one disc projecting into the spaces between the tooth-rings of the other. The fibrous material flows from a central opening in one disc outwards through the tooth-rings of the two discs and is delivered peripherally. The feed-stock of film material has a consistency of less than 15% of dry solids, and is advanced to the disc opening along a path in which it is concentrated by the progressive removal of liquid, so that when it arrives at the disc opening it has a consistency of at least 15%. As shown, material at a pumpable stuff density of 5 to 6% solids is fed into the inlet 16. It encounters an agitator arm 17 and then a worm 18 rotating in a perforated casing 19. This concentrates the material to 20 to 25% stuff weight, the separated water flowing out at 22. The worm press discharges into the orifice 11 of a housing 8 which has a stator 9 bearing two concentric rings of teeth mounted upon it. A rotor 6 mounted within the housing also has two concentric rings of teeth 7. As the material flows to the perimeter of the housing 8 it passes alternately between the teeth mounted on the rotor and stator. The water emerging from the outlet 22 is then pumped back into the material at 23. In a modification, not shown, the axis of the apparatus is vertical with concentration path above the discs. In this case, the pump 25 is not needed.

Abstract: 570,292. Engines using solid fuel. KRYGSMAN, D. Dec. 24, 1943, No. 21674. [Class 7 (ii)] In an opposed piston engine, finely divided solid fuel is injected at or about the commencement of the compression stroke. Fuel delivered to a passage 17 in the cylinder wall when the piston 12 is at or near the beginning of its compression stroke, traverses a radial passage 16 in the piston head and issues from an axial orifice in a semi - spherical hollow 13 in the piston head. The hollow 13 is bounded by a rim 14 adapted to telescope into a rim 15 surrounding a similar hollow 13 in the other piston 11 when the pistons approach their innermost positions, the hollows forming a spherical combustion chamber which persists over about 30 degrees of crank movement as one piston is given a corresponding lead over the other. In each piston, a space 20 between adjacent piston rings may be fed with compressed air delivered through pipes 23, 22 when the fuel injection occurs, or be connected by internal passages to the space between the pistons to avoid seepage of the fuel between the piston and cylinder wall. Lubricant may be supplied with the compressed air. The fuel may be injected through a porcelain nozzle member fitted in the hemispherical recess 13.

Abstract: 316,261. Associated Telephone & Telegraph Co. July 26, 1928, [Convention date]. Automatic exchange coin-freed apparatus; wall sets. - All the apparatus at a pre-payment substation is carried by a casing 11 which is locked to a base plate 51, connection with the terminals 48 on the latter being made by blade springs 47 so that the removal of the casing does not disturb any viring. The coin box 16 is padlocked to the casing. When the receiver is removed, a pin 31 adjustably carried by the hook lever engages the coin 50 and swings the shoot about its pivot 27 to change over the spring set 20 and so prepare the circuits for dialling. A shutter 45 on the hook lever covers the coin aperture 24. If no coin has been inserted the pin 31 passes idly through a slot in the shoot. When the called party replies, the push 28 is operated to remove the stop 29 from the. path of the coin and, by engagement of the pin 30 with the inclined projection 53 on the shoot, to free the coin from the pin 31 and allow it to slide into the box 16. The shoot then returns to its normal position and the springs 20 are restored to the talking condition If the line is busy the receiver is hung up to release the connection and allow the shoot to rise so that when the push 28 is operated the coin slides into the refund shoot 17. In this case the pin 30 moves clear of the member 53 but if an attempt is made to hold a connection and get the coin refunded by operating the button 28 without fully restoring the hook lever, the pin 30 engages the member 53 and swings the shoot downwards and the coin is collected.

After storing the form letter and form envelope code sequences, printing of the original of the form letter is started, blocks of variable data being stored as need for them becomes apparent from the form letter code sequence. Printing occurs from the form letter and variable data code sequences alternately, switching from one to the other under control of "switch" codes in both. "Skip" codes in the form letter code sequence causes the next field in the variable data code sequence to be skipped, with printing continuing from the form letter code sequence. Copies of the letter can be printed next, followed by the envelope, in a similar way. Thus some parts of the variable data can be used for letter without being used for envelope, and conversely. A code can cause further variable data to be stored automatically for further letters/envelopes. The memory is addressed by an incrementable and resettable address counter which can also load and be loaded by any of three address registers.
