Title: Washing and cleaning articles
IPC: B32B5/20
Filed: 1972-04-07
Abstract: 1390240 Laminates of cellulosic foam and fabrics NYLONGE CORP 7 April 1972 16144/72 Heading B5N [Also in Division C3] A water-absorbent product comprises a three-dimensional reticulated regenerated cellulose bonded fibre matrix, obtained by regenerating a foamed viscose having staple reinforcing fibres distributed therethrough, having at least one fibrous layer anchored in the face of the matrix. The matrix is preferably sandwiched between two fibrous layers. The product is made by depositing a foamed viscose whose alkalinity corresponds to a NaOH: dissolved cellulose ratio exceeding 0À9 (i.e. is greater than normal), on to a fibrous layer, depositing a second fibrous layer if required, and regenerating the cellulose. The matrix may contain at least 15 wt. per cent regenerated cellulose, and the dry product preferably contains 15-95 wt. per cent regenerated cellulose. The reinforcement fibres may be cellulose pulp fibres of length 1À5-4 mm. The fibrous layer may be a randomly oriented web or fleece of cotton or rayon or, less preferably, nylon, polyester or polyolefin, or may be a knitted, woven, mesh or open-pore fabric whose fibres are bonded at the points of intersection, cotton scrim and nylon netting being exemplified. The fibres of the outer layer(s) may be at least 10 mm. in length. The coating of each individual fibre preferably does not exceed 0À005 inch, The fibrous layer(s) preferably constitute 2-85 wt. per cent of the dry product with at least 20 wt. per cent of the total fibrous layers being embedded. In a preferred method of making the product, a first fibrous layer is deposited on a perforated belt or screen, the faomed viscose is deposited thereon and a second fibrous layer is deposited on the foam. The assembly is then compressed by belts or rollers and is coagulated, regenerated, washed, bleached and dried.

Numerous specific mixtures of tetra-alkyl lead compounds are given.  Of the monoto tetramethyl substituted benzenes those with higher degrees of substitution are preferred, although all possible compounds are specified.  The base fuels may be straight run, catalytically or thermally cracked, alkylates or isomerized materials, and may contain benzene and other aromatics, many of which are specified in the examples.  Other octane improving additives may be present, including methyl cyclopentadienyl manganese tricarbonyl, cyclopentadienyl nickel nitrosyl, manganese pentacarbonyl, iron carbonyl and dicyclopentadienyl iron.  Additional antiknock improvers referred to are carboxylic acid esters, e.g. tert.-butyl acetate, and amine salts of organic acids, e.g. isobutylamine isobutyrate, ethyl amine a -a -dimethyl propionate, and n-propyl amine propionate. Organohalide scavengers may also be used, those referred to being aliphatic and/or aromatic halohydrocarbons, haloalkyl ethers, and halohydrogen and halonitro compounds, specific mention being made of ethylene dibromide, ethylene dichloride, dibromotoluene, and 1,2,4-trichlorobenzene.

Title: Improvements in Change Speed Gearing.
Inventor: GRASSI FELIX AUGUSTE
IPC: F16H33/10
Filed: 1919-06-28
Abstract: 130,587. Grassi, F. A. July 27, 1918, [Convention date]. Variable-speed and reversing gearing comprisen a fly-wheel h subjected to two different oscillating motions adjustable in amount. A revoluble frame a secured to a driving-shaft M is attached so as to carry with it a frame c, the obliquity of which can be varied. The frame c is hollowed internally to act as a guide for the ends of the spindle f of the fly-wheel h. The spindle f, which is thus caused to oscillate like a pendulum, carries a bevel-gear j meshing with a gear i rigidly securerl to a frame fast upon a driven shaft R. The gear ; rolls to and fro on the gear i and imparts oscillatory rotary motion in addition to the flywheel h. Inertia resistances of the fly-wheel h cause the shaft R to be driven at a speed automatically variable with the load. Reversed driving can be obtained by additional gearing alternatively used. The device is applicable to motorvehicles.

Filed: 1937-06-15
Abstract: 497,332. Bending brake shoes &c. KELSEY - HAYES WHEEL CO. June 15, 1937, No. 16604. Convention date, July 22, 1936. [Classes 83 (ii) and 83 (iv)] In a machine for bending T-bar &c. to form brake-shoes &c., bending rolls angularly displaced about a master clamping roll are independently urged by fluid pressure means towards the master roll to effect bending and are tiltable to allow for variation in the thickness of the stock. The rolls are mounted in frames one of which is removable to allow of replacement of the rolls. The master roll 16 on a shaft 7 driven by an electromotor is split to form a clamp for the web of the stock and one part is forced axially to clamp the stock by an hydraulic cylinder unit carried on the shaft 7. The bending rolls 10, 11, 12, 13 are mounted on shafts in radial slides moved by pistons in hydraulic cylinders A fed by a pressure supply pipe 33. The pistons are formed with ball ends which contact with seats in crossheads carrying the shafts. The frame 4 is axially movable by operation of a screw 54. The rolls 10, 11, 12, 13 are driven by gearing from the shaft 7 through a ratchet which drives positively the shaft of the roll 10, but allows the shaft to rotate at a higher rate than the shaft 7. Cams on a shaft 43 driven by a chain 47 from the roll 7 move a stripper into the path of the finished brake band and operate the valve of the clamp cylinder to release the work piece.

Abstract: 1470334 Sulphuric acid RALPH M PARSONS CO 19 April 1974 [23 April 1973] 17280/74 Heading C1A [Also in Division F4] In a multiple contact/multiple absorption process for the manufacture of sulphuric acid, a positive flow of external heat is maintained into the ductwork leading from the absorption tower to the gas-to-gas heat exchanger by passing a fluid heating medium through an array of spaced tubes in contact with said ductwork, said tubes being surrounded by a reinforcing layer and an outside insulation to provide between said tubes a gas space heated by the flow of the fluid heating medium through said tubes, the flow of external heat into the ductwork being sufficient to maintain the gas stream above the dew point of sulphuric acid carried by the gas stream to maintain the acid in the vapour phase, thereby minimizing corrosion of the ductwork due to condensation of sulphuric acid on its surfaces. The gas-to-gas heat exchanger may contain a high temperature zone positioned at approximately the point of introduction of the gas stream from the ductwork, said zone being maintained at a temperature above the condensation temperature of sulphuric acid by the flow of gas from a conversion stage through said heat exchanger to prevent condensation of sulphuric acid on heat exchanger surfaces.
