Title: Improvements in or relating to bearings
Inventor: BATTISTA ORLANDO ALOYSIUS
IPC: F16C33/04
Filed: 1963-04-23
Abstract: 1,015,493. Bearings. FMC CORPORATION. April 23, 1963, No. 16005/63. Heading F2A. A bearing element is composed of cellulose crystallite aggregates or water-insoluble and organic solvent-insoluble derivatives thereof, the aggregates or their derivatives being of a size and size distribution such that at least 1% by weight, have a particle size not exceeding 1 micron in their greatest dimension and being bonded together in the bearing element in a solid mass by the attractive forces between the aggregates or their derivatives. Cellulose crystallite aggregates are a product obtained by the acid hydrolysis of cellulose, there being formed an acid-soluble portion and an acidinsoluble portion. The cellulose crystallite aggregates are disintegrated to the required particle size either by pressure or by a highspeed cutting or shearing action in the presence of a liquid. Lubricant, in the form of a liquid or a paste or dissolved in a suitable liquid solvent, may be applied to the aggregates either before or while they are being disintegrated or it may be applied to the finished bearing. The Specification refers to a number of derivatives of the cellulose crystallite aggregates including, for example, oxidation derivatives containing one or more carbonyl linkages including aldehyde, carboxyl and mixed aldehyde-carboxyl derivatives. In an example, a quantity of cellulose crystallite aggregates was subjected to a high pressure in a bearing-shaped, mould and lubricating-oil was then applied to the compressed bearing-structure. In another example, a quantity of cellulose crystallite aggregates powder was mixed with lubricating-oil and the mixture was subjected to high pressure in a bearing-shaped mould. The Specification refers to a number of water-insoluble and/or organic solvent-insoluble cellulose crystallite derivatives, including carboxy methyl, hydroxy propyl and acetate derivatives.

Title: Improvements in and relating to means for withdrawing and delivering measured quantities of liquids, applicable for delivering quantities of re-agent solutions in water treating apparatus
IPC: C02F1/68
Filed: 1925-06-22
Abstract: 254,499. Froude, R. H., Boby, W. V., and Boby & Co., Ltd., W. June 22, 1925. Moving - chamber apparatus. - A dipping and tipping cup, adapted for withdrawing a measured quantity of re-agent solution in a water softening, hardening, or purifying apparatus, and for deliverying it to water discharged from a tipper, consists of a vessel a with a lid b to prevent the contents from being spilled. The tipper, in the usual construction, receives a charge of water, and falls over when full; by means of suitable connections, the tipper lowers the cup into the solution, and lifts it to a point at which the cup is tipped on its trunnions j<1> so as to discharge the solution. The cup a is of elongated form, and the cover b, secured by countersunk screws c, leaves the spout open to allow the solution to enter and leave. To facilitate this, holes or slots are made in the cover. In a modification, the lid, which is imperforate, is hinged at one side or the rear, and is lifted by the impact of liquid as it descends. The lift is controlled by a stop near the hinge. Washers m may be strung on a rod k to enable the capacity of the cup to be varied.

Title: Improvements relating to sound reproducing means
IPC: H04R1/42
Filed: 1928-06-01
Abstract: 318,564. Green, H., and Celebritone, Ltd. June 1, 1928. No Patent granted (Sealing fee not paid). Phonographic reproducers; magnetic instruments. - Acoustic vibrations, direct or after amplification, or vibrations produced from a sound record are transmited by a pneumatic transmission system and are reproduced directly or after amplification. The pneumatic system may be maintained at atmospheric pressure, or above or below this pressure and serves to amplify the vibrations. As shown in Fig. 1, vibrations imparted by a record 7 through a stylus 6 to the movable member 5 of a bellows 2 are transmitted through a flexible inexpansible conduit 1 to a bellows 8, the movable member 10 of which carries a coil 13 on a former 14 which is thereby vibrated in the field of a pot magnet 11 and reproduces the sound through an amplifier 15 in a loud speaker 16. The pressure in the conduit may be maintained above or below atmospheric by a valved pipe connection 17 to a suitable pressure supply means, and in this case the vibrations may be produced in the conduit by a reed 19, Fig. 2, vibrated opposite to the end of the conduit by the stylus 6 or by a magnet influenced by currents set up by a microphone, which currents may be amplified before reaching the magnet coil. Alternatively, the transmitting bellows may be influenced directly by sound waves, and, as shown in Fig. 2, the receiving bellows 20 may operate directly a loud-speaker unit 22. Reference has been directed by the Comptroller to Specification 6042/86; 20925/12, [Class 40 (ii), Phonographs &c.]; 16549/13; 6079/14, [Class 40 (ii), Phonographs &c.]; 198,799; and 270,238, [Class 40 (ii), Phonographs &c.].
