Title: Improvements in and relating to laundry folding machinery
IPC: D06F89/00
Filed: 1949-07-25
Abstract: 693,351. Folding fabrics. MANLOVE, ALLIOTT & CO., Ltd., and BOAM, H. June 9, 1950 [July 25, 1949], No. 19534/49. Class 42 (ii). Articles delivered by an ironing machine to a folding machine are conveyed by a feed conveyer to a main conveyer on which folding is effected and which is driven continuously in one direction so as to convey the articles away from the feed conveyer at a speed greater than that at which they are delivered by the ironing machine so that it is ensured that successive articles received by it are spaced from each other. The folding machine may include the feed conveyer, the latter being driven at a lower speed than the main conveyer, and means being provided for pulling the articles off the feed conveyer at a speed faster than that of the feed conveyer. As shown, articles are fed from an ironer 12 to the main conveyer 10 of a folding machine, of the type shown in Specification 651,340, by a feed conveyer 16 comprising belts 18, 20 which feed the articles forward and upward and then downward and backward and are driven at the same surface speed as the delivery speed of the ironer. Conveyer 10 is driven at a higher speed than conveyer 16. A roller 26 forms a nip with the receiving end of conveyer 10 so that an article reaching the nip is advanced at the speed of conveyer 10 and is thus moved forward relative to the following article. Roller 26 may be replaced by a belt running around two rollers. The total length of belts 18, 20 must at least equal the length of the longest article to be folded, e.g. a 7 foot sheet. The ironer and folder may be driven independently, conveyer 18 being preferably driven by the ironer motor.

Abstract: 500,950. Solid paraffin hydrocarbons. STUDIEN - UND VERWERTUNGS - GES. July 17, 1937, No. 19878. Convention date, Aug. 1, 1936. [Class 2 (iii)] Solid paraffins are obtained from carbon monoxide and hydrogen by passage at pressures which are a multiple of the atmospheric pressure and at temperatures below 250‹ C. over immovable solid cobalt catalysts which have been impregnated with paraffins solid at room temperature so that the spaces between the catalyst particles are not filled, and which are so disposed that the paraffin formed during the reaction can drip continuously from the catalyst. The catalyst may be impregnated before the reaction or during the beginning of the synthesis. Pressures of 4 to 10 or 20 atmospheres may be used and the ratio of carbon monoxide to hydrogen is preferably 1 : 2, although other ratios may be used and diluents may be present. The reaction may be carried out in vertical or obliquely disposed reaction chambers, or the catalyst may be arranged on' perforated shelves etc. Examples describe the reaction of carbon monoxide and hydrogen in the ratio of 1.: 2 using a granulated reduced catalyst of cobalt, thorium and kieselguhr at 190‹ C. and pressures of 4, 10 and 20 atmospheres. The yield of solid paraffin increases with the pressure and the amount insoluble in boiling ether and melting between 110-114‹ C. also increases. The waste gases contain ben zine. If the catalyst is extracted after a lengthy period of use, paraffins melting at 130‹ C. or over are obtained. Specifications 255,818, [Class 2 (iii)], and 471,595 are referred to.

Abstract: 597,124. Preventing formation of ice on windscreens. VICKERS - ARMSTRONGS, Ltd., PIERSON, R. K., and FIRMAN, R. A. Aug. 10, 1945, No. 20570. [Class 20(iii)] [Also in Groups XXVIII and XXXIII] Means for spraying de-icing fluid on to a windscreen or windscreen wiper of an aircraft comprise a pressure head mounted in the airstream and a duct connecting the head with a storage reservoir, the arrangement being such that when an aperture in the head is blocked by ice-formation fluid in the reservoir is raised to the head and discharged into the airstream by aerodynamic suction, a combination of suction and pressure or by venturi effect. In one form, Figs. 1 and 2, a storage reservoir 12 containing de-icing fluid 13 and provided with a vent pipe 16 is housed in the fuselage 10 in front of the windows 11 of the fore part of the cockpit. A pipe 14 is mounted in the reservoir so as to project into the airstream, and its upper end 141 is bent at right angles to form a pressure head. The end of the pipe is provided with a small leak aperture 142, subjected in flight to a positive external pressure, and with lateral apertures 143 located in positions where, in flight, there is a subatmospheric pressure. As long as the aperture 142 remains free, the apparatus is inoperative, but, if the aperture is blocked by ice-formation, the suction at apertures 143 draws fluid up the pipe 14 and expels it in the form of a mist which is carried by the airstream into contact with the windows 11. The fluid passing through the pipe 14 tends to dissolve the ice blocking the aperture 142 so that when icing conditions no longer exist the aperture is cleared and the apparatus ceases to function. In a modification, Fig. 3 (not shown), the lifting effect in the pipe 14 is augmented by an outer tube 15 having an inlet exposed to the dynamic pressure of the airstream. The inlet is kept free of ice by fluid discharged from the apertures 143.
