Title: Process for effecting the addition of bisulphites to epoxy compounds
IPC: C07C309/08
Filed: 1963-11-26
Abstract: In a process for preparing hydroxysulphonic compounds by reacting bisulphites (including metabisulphites) with an epoxy (i.e. oxirane) compound, at least part of the bisulphite is used in the form of an adduct with an oxo compound; alternatively a hydroxysulphonic acid salt which could have been obtained from a bisulphite and an oxo compound may be used although prepared by a different method.  The adducts may be prepared in situ by the separate addition of a bisulphite and an oxo compound but are preferably preformed. Preferred oxo compounds are saturated aliphatic aldehydes of at most 7 carbon atoms and saturated aliphatic ketones of at most 7 carbon atoms having no functional groups other than the carbonyl group or possibly one hydroxyl group.  Preferably the molar ratio of adduct to epoxy compound is 2:1 to 8:1.  A solvent or dispersant may be used, preferably an aqueous C1-4 alcohol. Temperatures of from 40 to 150 DEG  C. are mentioned. In a preferred embodiment, the reactants are first heated together in a medium containing less than 10% by weight of water, and water is later added and heating continued.  Examples describe the reaction of glycidyl esters of C9-11 or C15-19 carboxylic acids with acetone-sodium bisulphite adduct.  Other suitable epoxy compounds preferably have at least 7 carbon atoms and include epoxidized hydrocarbons and epoxybutyl or glycidyl alkyl ethers or esters of aliphatic or araliphatic saturated monocarboxylic acids such as those of formula R1R2R3CCOOH, where R1 and R2 are alkyl and R3 is alkyl or hydrogen (see Specification 974,124).  The glycidyl esters of C9-11 or C15-19 carboxylic acids used in examples are prepared by reacting C8-10 or C14-18 olefin fractions (from cracking paraffins) with carbon monoxide and water in the presence of a complex of phosphoric acid, boron trifluoride and water, forming an aqueous solution of the sodium salts of the resulting C9-11 or C15-19 acids and adding this to epichlorhydrin with azeotropic removal of water.

Filed: 1973-10-10
Abstract: 1402390 Braking hand propelled vehicles; brake hand-levers A MANNS 10 Oct 1973 47335/73 Heading F2E In a luggage transport truck comprising a basic frame for receiving the goods to be transported, a frame including two uprights at one end of the basic frame, a pushing or pulling handle associated with the upper ends of the uprights, and a braking device which is actuatable by rods or tubes running inside the uprights, the pushing or pulling handle itself serves as the actuation element for the braking device and for this purpose is articulated to the uprights, the braking rods being coupled to the handle in such a way that when the truck is at rest the rods are located in their operative position, but the rods are moved to release the brakes at least when the handle is depressed, but preferably when it is depressed or raised. Fig. 1 (not shown) depicts an arrangement where the brakes are released only when the handle is depressed. As shown in Figs. 2 and 3, pushing a part of handle 3 (not illustrated), to push the truck, results in clockwise pivoting of the end 3a of the handle about a stop 13 whereby a hollow braking rod 4 is raised by a pin connection 10 with the handle end against the pressure of a spring 16 to release the brake (not illustrated) from a rear wheel of the truck. Similarly, when the handle is pulled, counter-clockwise pivoting occurs, this time about a stop 12, whereby the brake rod 4 is again raised to release the brake. Spring 16 is pre-stressed, and the braking force may be changed by changing the prestressing. Alternatively the braking force may be changed by changing the effective length of braking rod 4 in the manner shown in Figs. 5a, 5b. An extra tubular piece 20 is interposed between rod 4 and the upright 1, and it is piece 20 which has holes corresponding in size to pin 10, while rod 4 is slotted at 25. Tubular piece 20 is now raised or lowered by action of handle end 3a, while the vertical position of rod 4 relative thereto is pre-selected by manipulation of a bolt and nut connection 24, 23. A brake shoe is located at the lower end of each braking rod 4, the shoe, on application, acting in a wedge-like manner with increasing force against the side of the rim or tyre as the wheel rotates.

Title: Improved fibre mat at least partly formed from glass fibres
IPC: D04H3/03
Filed: 1964-11-23
Abstract: A fibre mat composed partly of glass fibres comprises a band of fibres laid in zig-zag form from one side of the mat to the other successively in the direction of the length of the mat, the band comprising a plurality of parallel strips each formed of a strand of fibres arranged along the band in substantially flat overlying loops, the mat comprising strands of at least two different degrees of fineness.  Continuous glass filaments 23 are drawn through the orifices of bushings 21 depending from glass melting tanks (not shown) and size is applied thereto by applicators 25, Fig. 2 (not shown).  The filaments from each bushing are then grouped together to form sets of strands individually segregated as they travel within grooves in gathering shoes 27, 27b, varying numbers of filaments being grouped together to form strands of varying degrees of fineness.  The sets of strands 28, 29 pass under grooved aligning shoes 31, around idler wheels 33 and around pull wheels 35, 36 driven by motors 38.  The wheels 35, 36 each carry on an independently mounted oscillating back plate 42 a spoke wheel 39 to project the strands tangentially therefrom, Figs. 3 and 4 (not shown).  The groups 58 of strands from each wheel 35, 36 are accumulated in a mat 60 on a conveyer 61 of carbon steel chain construction.  Adjustable shields 63 define the edges of the mat 60.  The pull wheels 35, 36 are formed with slots through which the fingers of the spoke wheels 39 successively project.  The size applied by the applicators 25 may be water or may be a primary binder and a powdered synthetic resin may be subsequently applied.  The mat 60 passes from conveyer 61 to a further conveyer and thence through an oven for curing the binder, Fig. 1 (not shown).  The varying degrees of fineness of the strands may be achieved by employing coarse glass fibre strands and finer strands of wool, cotton, rayonacrylics, vinylics, nylon, aluminium silicate, asbestos or glass.  A composite mat may be thus formed with a plurality of bands, each comprising strands of one degree of fineness, or sets of strands of varying degrees of fineness.  The mat may comprise distinct layers with various sizes or weights of strands in different layers but also in combination in the same layer.  The ratio of finer to coarser strands in the mat preferably increases from the central plane outwards.
