Abstract: 1328326 Reciprocating pumps SOC TECHNIQUE DE PULVERISATION 3 Aug 1972 [19 Aug 1971] 36255/72 Heading F1A A spray pump comprises a piston 7 reciprocable by a tube 8 with a spray head 16, and a valve 9 which is opened on initial depression of tube 8 which on further depression moves piston 7 downwardly to pressurise liquid in cylinder 4, reduced thickness portions 7c of piston 7 uncovering tube parts 14 when the pressure has risen sufficiently to produce correct atomisation, and axial ridges being provided in the cylinder to deform the piston towards the end of its downward stroke to form clearances permitting escape of air from the cylinder for priming. Container 2 is vented via port 13 during pump operation, the vent passage being closed by piston portion 7d in the rest position shown. In Fig.4 (not shown), the tube ports are permanently open, and tube 8 engages the piston via a spring which prevents opening of the valve 9 until a sufficient discharge pressure has been developed.

Abstract: 322,647. Broadhurst, T. H. Dec. 10, 1928. Fourdrinier paper-machines; wire-cloths.-The endless wire 20 of a Fourdrinier paper-making machine can be more easily replaced by moving the whole table frame sideways, clear of the space between the suction roll 19 and the breast roll 16 by gearwheels 34 moving racks 28 secured on the cross frames of the table. The gear wheels 34 are driven by chains 37 from a shaft driven by an electric motor 21 or in case of breakdown a handle slipped on the end shaft 47 may be used. To support the overhang of the table during displacement, hinged arms 29 are secured to the side frames 12 which when opened out align with the cross beams 26 and support the weight until the table itself travels out to rest on support rollers 32, Fig. 3, when the arms 29 are free to be hinged back alongside the frame sides, leaving a clear space for placing the endless wire 20 in position. The wire is temporarily held in position by suspending rods; the arms 29 are then hinged out again and the table is traversed back to working position. The wire suspending rods are then withdrawn and the wire adjusted.

Abstract: 1,158,784. Textile treating apparatus. C. DUCKWORTH. 18 Aug., 1966 [27 Aug., 1965], No. 36851/65. Heading D1L. Apparatus for the fluid treatment of textile material comprises a rotatable impellor having an asymmetrical peripheral surface constituted by crests and hollows defining channels extending parallel to the impellor axis to subject material in contact or near contact with the impellor to a fluid centrifugal force. The peripheral surface of the impeller is preferably of saw-toothed configuration with the tip of each tooth rounded. The impellor may be hollow and fluid is then fed to the interior of the impellor and leaves via perforations in the surface. The impellor may alternatively, comprise angularly-spaced curved blades mounted on radial spiders extending from a central shaft. The impellors are preferably employed in apparatus comprising a liquid trough 21, a plurality of the impellers 22 rotatably immersed in the liquid, and a plurality of guide rollers 24 arranged so that the material 27 follows a sinuous path through the apparatus. Rubber covered dance rollers 25 may be provided between adjacent guide rollers 24. Pipes 31 may be provided to inject steam or air into the space above the liquid level in the trough, a cover being provided over the top of the trough to prevent escape of steam or air. A mangle 26 is provided at the exit end of the trough to remove excess liquid from the material before it passes to further processing apparatus. The mangle 26 serves to draw the material through the apparatus, and in addition, the impellors and guide rollers may be positively driven or may be driven by material contact. Several such apparatus may be arranged in series with a conveyor belt, J-box or the like therebetween. Partitions 23 are preferably provided between adjacent impellors and are attached to the side walls of the trough at opposite ends, so that liquid fed concurrently or countercurrently with respect to the material follows a sinuous path. The base of the trough may comprise heat exchange panels to effect heating of the liquid. The level of liquid in the trough is controlled by means of an overflow 29.

Title: Cable winch
Inventor: TURNQUIST EDWIN W
IPC: B66D1/74
Filed: 1961-10-18
Abstract: 981,526. Multiple drum winches. NAUTEC CORPORATION. Oct. 18, 1961, No. 37336/61. Heading B8B. A winch comprises two peripherally grooved hauling drums 13, 14 which are driven to move the load and a storage drum 17 which feeds cable to and from the hauling drums. The grooves in each of the hauling drums are progressively reduced in diameter over at least the first two turns reckoned from the end where the loaded cable C leaves them, i.e. from the left in Fig. 2. The end turn 13g of the groove on one of the drum 13 stands a little proud of the corresponding end turn of the other drum 14. This turn 13g is formed in an overrun pulley 28 on the same shaft as the remainder of drum 13, the pulley being driven with the drum in one direction of rotation thereof but not in the other. The winch is driven by a worm drive contained in housing 12 and directly coupled to the twin drums 13, 14. To keep the cable between the hauling drums and the storage drums taut during winding the worm drive is also coupled to storage drum 17 through gearing causing it to rotate somewhat faster than the hauling drum but incorporating a frictional clutch. The drum 17 and overrun pulley 28 of drum 13 are both driven when the winch is winding but are not driven when it is unwinding. The unidirectional coupling of the drive to these members is achieved in each case by the use of a clutch such as is shown in Fig. 7. When the drive shaft 45 of this clutch is rotated in the direction indicated a cam member 44a carried thereby simply pushes rollers 66 in a circular path along the interior of annular cage 67 without rotating the latter. When the drive shaft 45 is reversed however the rollers 66 are wedged between cam 44a and cage 67 so that the latter is driven. To ensure even laying of cable on storage drum 17, the winch may incorporate a swinging guide 69, Fig. 2.

Title: Polyurethane pressure-sensitive adhesives
Inventor: WELLER BRION
IPC: C08G18/32
Filed: 1964-09-18
Abstract: A pressure-sensitive adhesive is made by reacting one or more polyols having at least 3 OH groups per molecule, with or without one or more diols and/or one or more mono-ols, and the stoichiometrical amount of an organic polyisocyanate, the OH-containing compounds being in sufficient proportions dependent on their molecular weights to produce a fully cross-linked reaction product with the isocyanate, the reaction product having an average chain length of from 130 to 285 chain-atoms.  Reactants specified are: polyols-sorbitol, arabitol, pentaerythritol, glycerol, and reaction products of these with propylene oxide and/or ethylene oxide; diols-polyethylene glycol and polypropylene glycol; mono-ols-methyloxitol and n-butanol; polyisocyanates-4,41-diisocyanato-diphenylmethane, 2,4- and 2,6-tolylene diisocyanates, hexamethylene diisocyanate, triphenylmethanetriisocyanate, 2,4,41 - triisocyanato-diphenylether, and polymethylenepolyphenylisocyanate. Usually an accelerator, e.g. dibutyltin dilaurate or stannous octoate, is added to the reaction mixture prior to curing. Antioxidants may also be added.  The method of calculating the chain length in terms of numbers of atoms is described.  In a typical Example (1) various triols were individually mixed with 4,41-diisocyanatodiphenylmethane, in the presence of dibutyltin dilaurate, and cured at various temperatures to yield pressure-sensitive adhesives.  The reactants are preferably applied in liquid form to a substrate, such as a paper or cloth fabric or a thin plastic sheet, whereon they react to form the adhesive.ALSO:A pressure-sensitive adhesive polyurethane, having an average chain-length of from 130 to 285 chain-atoms, is formed in situ by applying the reactants, viz one or more polyols containing at least 3 OH groups per molecule, with or without diols and/ monools, and organic polyisocyanates.  (see Division C3), in liquid form to a substrate, such as a paper or cloth fabric or a thin plastics sheet, whereon they react at room or elevated temperature to form the desired adhesive.
