Filed: 1957-12-12
Abstract: 827,941. Grinding. WINKLER, R., and DUNNEBIER, K. Dec. 12, 1957 [Jan. 26, 1957], No. 38615/57. Class 60. A method of producing openings in paper or like material, such as the windows in window envelopes, consists in guiding the material over protruding edges of the size and shape of the opening and grinding away the material at the places in contact with the edges. In a machine for carrying out the method, the material, which may be in the form of blanks or a web, is fed from a roller B on to a rotatable cylinder A, against which it is pressed by resilient rollers F, G of rubber or other yieldable material disposed adjacent a grinding wheel C. The cylinder A comprises a hollow cylinder 6 on which is fitted a segmental portion 2 and a hollow or perforated block 8 disposed between guides 71 secured at each end of the cylinder 6. A thin steel band 1 or the like, which is approximately 0À1 nun. thick and corresponds in contour to the shape of the opening to be produced, projects edgewise from the portion 2 and is secured thereto by marginal strips 4, 5 and a core 3. The block 8 is disposed with its surface at the same radius as the surface of the guides 7<SP>1</SP> and strips 4, 5 and core 3 securing the band, and is connected to a suction conduit, whereby the drawn through orifices 8a, 8b in its surface assists in holding the envelope material against the cylinder. In operation, the material fed from the roller B is held against the cylinder A as it rotates to periodically bring the steel band into contact with the grinding wheel, which can be adjusted in a direction perpendicular to its axis by a screw 15 and nut 16 controlled through gearing 17 from a handwheel 18, so that the wheel grinds through the material where it contacts the steel band. The waste portions 19 inside the band are blown from the cylinder into a collector H by compressed air fed through orifices 13 to the space confined by the steel band, and the blanks or web of material are carried by a guide roller D to the next operating stage in the production of the envelopes.

Abstract: 844,194. Filtering and coalescing devices. BRITISH FILTERS Ltd. Oct. 8, 1958 [Dec. 13, 1957], No. 38849/57. Class 46. In the liquid separator 1 the cartridges 2 are formed from a filtering medium comprising a mixture of diatomaceous earth and fibrous material, the earth forming the major portion by weight, supported in a basket 13 and are capable of effecting both coalescing and separating operations when used to filter a hydrocarbon liquid containing entrained water. The contaminated liquid enters through the inlet pipe 9, the flow being distributed over the division plate 6 by a baffle 10, and a series of substantially horizontal settling trays 15, extending from the division plate 6 beyond the ends of the cartridges 2 to a drain pipe 16, serve to collect the separated water and transport it via the drain pipe 16 to a sump 17. The cleaned hydrocarbon passes through the perforated baffle plate 19 to the outlet 18. The horizontal extent of the trays 15 may be varied in accordance with the degree of separation efficiency required. The separation efficiency can also be increased by providing the cartridge material with a surface coating of a more hydrophilic character than the separator medium. Pressure gauges may be connected to the inlet and cartridge chambers for measuring the pressure drop. The separator can also act as an effective filter for solids. Specification 820,286 is referred to.

Abstract: 827,344. Electric measuring devices. SVENSKA FLYGMOTOR A.B. Dec. 23, 1957 [May 10, 1957], No. 39977/57. Class 40 (1). [Also in Group XIX] A pressure gauge comprises a hollow body capable of being set in vibratory motion; the impingement on the interior and exterior surfaces of the body of media whose pressures are to be compared varies the natural frequency of vibration of the body, which is measured to ascertain the differential pressure. As shown, a thin-walled hollow cylinder 1 of magnetic material, closed at one end, is mounted within a housing 5, and a solid coil frame 3, carrying two coils 10, 11, at right angles to one another, is fastened within the cylinder 1. The media, one of which may be at a reference pressure, are introduced into the spaces on either side of the cylinder through openings 8, 9. Coil 10, which has a soft iron core 12, is energized by D.C. with an A.C. component, the frequency of which is adjusted until the voltage induced by the vibration of the cylinder in coil 11, which has a permanent magnet core 13, attains a maximum value. Alternatively, the coils may be connected together via an amplifier so as to produce a self-vibrating system, a frequency meter being provided in the amplifier circuit. Temperature compensation may be obtained when a test pressure is applied to the external surface of the cylinder 1 by hermetically closing the space inside the cylinder; the variation of pressure within said space consequent on a change of ambient temperature is said to counteract the variation of elasticity in the material of the cylinder 1.
