Title: Polymers of alpha, beta-unsaturated aldehydes and the process for their production
IPC: C08F246/00
Filed: 1945-07-30
Abstract: Polymers of an alpha, beta-unsaturated aldehyde are produced by reacting the aldehyde with a carboxylic acid anhydride or halide to form the corresponding diester, polymerizing the diester and then hydrolysing the polymer.  Suitable aldehydes include acrolein, substituted acroleins, crotonaldehyde and substituted crotonaldehydes, and compounds represented by the formul <FORM:0596620/IV/1> and <FORM:0596620/IV/2> The anhydrides may be of mono- or poly-carboxylic, cyclic or acyclic acids, acetic anhydride being preferred.  Suitable halides are acetyl chloride and bromide, propionyl chloride and bromide and their homologues.  The esterification may be carried out in the presence of a catalyst such as sulphuric or oxalic acid, stannous or stannic chloride and ferric chloride, at temperatures up to 20 DEG  C.  Polymerization may be effected with peroxide catalysts with or without diluents such as aliphatic or aromatic hydrocarbons.  Copolymers may be produced by hydrolysing the copolymers of two or more different diesters. Specified hydrolysing agents include strong mineral acids and strong bases. During the hydrolysis the polymer may be kept in solution in an alcohol, ketone, or an aliphatic or aromatic hydrocarbon.  High concentration of catalyst and heating will produce cross-linking. On standing or by the action of dilute acids or bases, the polymeric aldehydes can be converted to gels which can be infusibilized by heating with or without peroxides, acids, bases or salts.  One or more polymeric aldehydes may be condensed with one or more phenols or with amides such as urea or amines such as aniline.  These products are useful as coatings, moulding compositions, laminates and castings.  Acetals may be produced by reaction with one or more monohydric or polyhydric alcohols which may be saturated or unsaturated.  Polymeric allyl-type alcohols are produced by hydrogenation of the polymeric aldehydes, e.g. by treating with gaseous hydrogen at 150-250 DEG  C. under pressure in the presence of a nickel catalyst.

Title: An improved machine for folding fabric or the like
IPC: A41H43/00
Filed: 1939-07-05
Abstract: 531,559. Folding fabrics &c. BAKER (LEICESTER), Ltd., W., BAKER. C. M., and MOORE, A. A. July 5, 1939, No. 19583. [Class 42 (ii)] A fabric &c. F to be laid in folds for cutting-up &c. is fed by rolls 22a, 22b through guides 35a, 35b on to a table 11 which is reciprocated at a varying speed, e.g. by a crank-pin 18, quadrant 16, pinions 15, 14, and rack 13 and the rate of feed by the rolls 22a 22b varies with the speed of the table. As shown, this is effected by driving each of the intergeared rolls 22a, 22b by a chain 30a, 30b and a free wheel from a shaft 28 geared to the pinion 14. Between the free wheels and the shaft 28 there is some lost motion so that the feed is nil at each end of the stroke of the table. The guides 35a, 35b are raised as the folding proceeds by cords 37 and a shaft 38 which may be rotated by hand. Rollers 44a, 44b for smoothing the laid fabric are alternately raised from and lowered on to the folded fabric by cords 47a, 47b and a crank on the shaft 49. The throw of the crank-pin 18 is adjustable. When folding tubular knitted fabric a spreader is inserted before the feed rolls 22a, 22b.

Title: Improvements in or relating to envelope making machinery
Inventor: NOVICK ABRAHAM
IPC: B31B19/00
Filed: 1957-06-22
Abstract: 826,202. Making envelopes. SMITH MACHINE CO. Inc., F. L. June 22, 1957, No. 19721/57. Class 94(2). [Also in Group XVI] In a machine for making envelopes, blanks are fed lengthwise for the performance of certain operations thereon to a transfer station where they are fed lengthwise by continuously acting rotary means, depressed on to a support at a lower level by further rotary means, yieldingly fed lengthwise into engagement with stop means, engaged by lugs on continuously driven endless conveyers, while their original trailing edges are still engaged by the depressing means, and fed sideways by the lugs. A blank 10a, Figs. 1 and 2, with a side flap 14 already folded over the other side flap 12, is fed lengthwise to the left by a driven roller 18 and discs 20 and then by a driven roller 22 and discs 24, 26, the leading edge being held flat against fingers 99 by air blasts from a pipe 97. The blank is thus fed on to a table 30, 32, 34, beneath guide fingers 40, 42, 57 and a spring finger 50, and between a driven roller 48 and balls 54 resting by gravity thereon in tubes 56, whereby it is resiliently fed against a stop bar 36 and beneath a guide bar 58. In order to lower it on to the table, the blank is engaged by depressing means comprising a series of cam discs 86, 88, 90, 92, 94, 96 on a continuously rotating shaft 84, each disc being shaped as shown in Fig. 2, but with the low points angularly staggered from disc to disc. Alternatively, the shaft 84 may carry a solid body having each corresponding crosssection the same as that of the equivalent disc, with each such cross-section progressing smoothly into the next. Continuously driven endless conveyer chain 72, 73 each carry two equivalent lugs 74, 75 projecting on that upper run through slots between the table sections 34, 32 and 32, 30. Each blank is engaged by a pair of lugs 74, 75 while still held down by the depressing means and fed sideways (downwards in Fig. 1). The lug 75 reaches each cam disc just after the low part thereof moves into its path to allow it to pass, and the blank is fed to a feed couple comprising a lower driven roller 76 and two upper segments 78 having high and low portions and driven at two revolutions per cycle so that active and idle revolutions occur alternatley. The feed of the couple is faster than that of the lugs and the blank is thereby drawn clear of the lugs to allow the latter to run on to their lower runs. The blank then passes to a second couple comprising a lower driven roller and two complete upper discs and driven at the same speed as the first couple, and passes therefrom to stations for further operations to be performed on it.

Abstract: 668,651. Fuel supply; regulating; cooling. MARTIENSSEN, L. E. July 28, 1949, No. 19887/49. Classes 7(ii), 7(iii) and 7(vi) In an improved method for the production of combustible mixtures for internalcombustion engines, a low-octane fuel, such as paraffin, is admixed with the air supplied to the engine in proportions controlled by variations in the pressure of a head of engine exhaust gas in direct contact with the liquid body of the low-octane fuel; there is also provided apparatus comprising a low-octane fuel tank 27, Fig. 3, an automatic control device with a gas tight container 33 to the top of which an exhaust gas line 34 is connected, a valve 35 operated by a float 36 for regulating the flow of fuel to the container 33, a line 31 taking low-octane fuel from the container 33 to a carburetter 32, an adjustable valve 39 in the line and a tank 48 containing ordinary or higher grade petrol. The water from an air-tight tank 1, Fig. 1 is led by a pipe 3 to a jet 4 situated either in front of a choke 6 or in an air filter 7. Gas from the exhaust pipe 8 is introduced into a conduit 11 to both pressurize the tank 1 and operate a. spring-loaded diaphram 15 which, through a number of Bowden cables, conjointly controls a valve 21 in pipe 3, the diameter of jet 4, ignition advance and retard, an extra air valve in the inlet manifold, a bi-fuel control and a fuel proportion indicator, the last four members not being shown. Paraffin from the main fuel tank 27, Fig. 3, is pumped to an automatic control device 30 comprising the container 33 pressurized by exhaust gas entering the conduit 34. Upon an increase in engine output the increase in exhaust pressure forces paraffin through a coil 43 in a chamber 41 heated by the engine cooling water traversing pipes 44 and 45; the paraffin passes into the line 31 via the adjustable valve 39, which may be of the needle type, the line 31 opening into the float chamber of the engine carburetter 32 that also receives petrol from the auxiliary tank 48 under the control of a float controlled valve 47. The petrol feed may be effected by gravity or exhaust pressure. In a modification, the paraffin, which is heated, is contained in a exhaust pressurized auxiliary tank whilst the petrol is stored in the main vehicle tank and a fixed or adjustable needle valve operated as in Fig. 1 is placed in the paraffin line. Water is always added to the air-fuel mixture before it reaches the engine cylinder. The size of the carburetter float chamber may be reduced by the insertion of a lead or plastic coating. The high octane fuel may be gravity fed whilst the low octane fuel may be heated by the engine cooling water.
