Title: Improvements in Folding Umbrellas.
Inventor: ERICKSON ALBERT JOHN
IPC: A45B19/10
Filed: 1916-08-15
Abstract: 108,830. Erickson, A. J. Aug. 15, 1916. Folding and telescopic umbrellas; ribs and strctchers.-The ribs 20 each consist of two sections 47, 48 pivoted together and to a stretcher 37 by a common pivot 38, the stretcher being formed with an opening 55. The sections 47 are each secured in extended position by a spring catch 50, which is attached to a reinforcement 49 on the section 47 and is formed with a loop 52 adapted to snap over the end of the section 48. The loops prevent the joint pads 54 arranged over the pivots from being caught when the ribs are folded. The loops pass into the openings 55 when the umbrella is closed. To prevent the sections 48 from passing through the openings 55, and thus unlocking the catches 52, when the umbrella is closed, the ends of the sections 48 are provided with enlargements which hold the stretchers slightly out of line with the ribs. The rib sections and the stretchers are of channel shape and nest together when the umbrella is collapsed. The staff is preferably constructed as described in Specification 107,687, and comprises telescopic sections 14, 15 and a telescopic tip section 16 provided with a spring catch 30 for confining a spring collar 40 which engages the runner 36 internally. To collapse the umbrella, it is first closed and the rib sections 47 are folded. The runner is then lifted to re-engage the collar 40 and the staff is telescoped, the section 14 entering the runner and disengaging the catch 30. Further telescoping moves the collar 40 against the top notch 19 and the runner is then lifted to engage the collar, and the tip section 16 is telescoped after releasing a catch 23. Covers.-The cover 21 is attached to the sections 48 by loose threads 60, Fig. 9, which are arranged to permit the sections 47 to fold into the sections 48 and to prevent the threads from rubbing on the stretchers on closing the umbrella. The threads 60 pass through the seams 58 and apertures 57 in the sections 48 and are tied underneath, the only parts of threads that are exposed passing into the openings 55.

Title: High molecular weight polymer detergent compounds and method of making the same
Inventor: LUNSTED LESTER GORDON
IPC: C11D1/722
Filed: 1952-03-10
Abstract: Propylene oxide chains are attached by polymerization to a compound with one or more reactive hydrogen atoms to produce a polymer with an average molecular weight of 900 which is then reacted with ethylene oxide to produce a product having detergent properties and with 20-90 per cent of its weight as oxyethylene groups.  The preferred starting material having reactive hydrogen atoms is propylene glycol.  Others mentioned are glycerol, pentaerythritol, sucrose, ethylene diamine and acetamide.  In a typical example, propylene oxide was introduced as fast as it would react into a solution of sodium hydroxide in propylene glycol heated to 120 DEG  C. with an atmosphere of nitrogen.  After cooling, neutralization of the soda and filtering a product was obtained with an average molecular weight of 1620 determined by hydroxyl member or by acetylation.  Sodium hydroxide was added to this product which was then similarly reacted with ethylene oxide to produce a product of average molecular weight of 2680.  A number of similar examples are described employing varying proportions of the two oxides and comparisons are made of their properties of cleaning and whitening cloth.  Specification 443,559 is referred to.

Two plate members 38 are attached to each beam at third intervals and the arrangement is such that essentially all stress in the bars 45 is longitudinal stress and during expansion and contraction of the shell, the magnitude of the longitudinal stress in said bars 45 and the magnitude of the stress in said ring member 31 fluctuate but without decreasing to zero stress and undergoing reversal of direction of stress. Additional smaller radial gussets (40, 41, Figs. 2 and 4) are welded to the shell and to the top of the ring 31. On either side of a gusset 39 these have lateral stiffeners (42) welded to the upper ends of all three gussets. Other lateral gussets (43, Fig. 2) are welded to the outer edges of all the gussets and to the ring 31 forming an octagonal ring around the shell. Each gusset 39, 40, 41 is associated with a further gusset 39a extending inwardly of the shell into the refractory lining and formed with openings 49.  An auxiliary frame is formed by an octagonal ring member 51, Fig. 5, welded to the top flanges of beams 32. Tie rods 53, 54 with associated turnbuckles 57, 64 extend between this frame and members 55, 61 welded to the shell, adjacent tie rods crossing one another as shown. The legs 26, Fig. 11, are initially supported off centre and moved outwardly to prestress them. A strong steel flange 71 welded to the lower end of each leg carries a hemi-spherical ball portion 74 on a base-plate 75, its axis Y being displaced by a predetermined distance Z towards the furnace axis. During erection the ball portion 74 of each leg seats in a mating socket (76) in a temporary adjustable base 77 comprising a slide block 80 formed with the socket (76) disposed within a base formed with side walls and end walls 86, 87. The base 82 stands on adjustable legs 91 in a recess 79 in a permanent concrete base 27 and after positioning therein is grouted in by concrete 94. Once the lower portions of legs 26 have been moved to the desired prestressing position nuts 97 on anchor bolts 73 extending through the flange 71 are partially tightened and the space 98 below the flange is filled with concrete. When this hardens the nuts 97 are fully tightened. The legs may be wholly or partly filled with a non-shrink concrete. The furnace is provided with conventional cooling elements 48.

Title: Improvements in or relating to the manufacture of artificial threads strips or bandsfrom protein solutions
IPC: C21D9/00
Filed: 1939-02-27
Abstract: 525,738. Artificial filaments &c. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGSINSTITUUT RESEARCH. Feb. 27, 1939, No. 6462. Convention date, March 29, 1938. [Class 2 (ii)] Artificial threads, strips, or bands are produced from an alkaline protein solution by extruding the solution into an acid spinning bath, and the freshly formed threads or other products are subjected to a continuous operation comprising a treatment with one or more hot salt solutions and a stretching by means of driven rollers or godets, the peripheral 'speed of each roller being greater than that of the preceding roller in the series. Stretching of the thread takes place while it is in contact with the hot salt solution. The thread is subsequently hardened with formaldehyde while it is in an untensioned state. When more than one salt solution is used these may be of different concentrations and at different temperatures. Salt solutions used include sodium sulphate, magnesium sulphate, zinc sulphate, aluminium sulphate, and sodium acetate. The thread may be cut to staple fibres before the formaldehyde treatment. In an example, a solution of casein in caustic soda solution is spun into a warm bath of dilute sulphuric acid, magnesium sulphate and sodium sulphate. The thread obtained is passed over a series of rollers rotating at increasing peripheral speeds, each roller being immersed in a hot solution of sodium sulphate. The thread is cut to staple fibre and treated with formaldehyde. If the temperature of the salt bath is sufficiently high the thread becomes stabilized so that it does not shrink during the subsequent hardening process. If the temperature of the salt bath. is below 80‹C., the bundle of filaments may be stabilized by passing it after the stretching treatment through another bath by means of rollers having the same speed as the last of the stretching rollers.
