Filed: 1916-10-30
Abstract: 110,041. Voorhout, A. W. C. van. Oct. 30, 1916. Phenol-aldehyde condensation products.-In the manufacture of hard insoluble infusible products from a phenol and formaldehyde, the phenol and formaldehyde are heated with a small quantity of basic catalyst until all the solvent water and about half of the water formed by the condensation reaction is driven off, after which a neutral liquid other than water is added to prevent too great a rise in temperature and the final stages of the process are effected slowly at a moderate temperature without employing pressure. According to examples :-Pure phenol or cresol, formaldehyde solution, and a small quantity of caustic potash are heated and stirred until all the water originally present and about half the water formed is distilled off, ethyl or methyl alcohol is then added, the heating continued until half the alcohol is distilled off, the mass is then run into open moulds and dried slowly in a current of air at a temperature rising from 60‹ C. to 115-120‹ C.; instead of alcohol, a mixture of oil of turpentine and glycerine, with or without vaseline, and colouring-matters, is used.

Filed: 1930-05-21
Abstract: 346,211. Inlaid linoleum. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A.- (Assignees of Wiley, J. E. ; Lancaster, Pennsylvania, U.S.A.) May 21, 1930, No. 1566]. Convention date, May 24, 1929. [Class 140.] To obtain a pattern of greater repeat length, a die roll 3 of a rotary inlaying machine is arranged so that certain strippers 16a, 16a<1>, 16a<11> actuated by the same elenent, e.g. by the pin Sa on the scrap roll 8, discharge pieces of different size or shape. As shown, the strippers 16a<1>, 16a<11> have square heads which discharge square pieces of scrap to form gaps at X, X, Fig. 5A, and squares S<1>, S<11> are laid adjacent to these by the pattern roll 18. The stripper 16a has a similar square head but discharges a piece of scrap of twice the size, to form an oblong gap SX, and the part S of this gap is not illed by the pattern roll 18. The pattern may be completed by a further die roll or rolls, leaving squares S to be filled in by hand, as at 22, as the material passes over an inspection table. Thus the general pattern formed by the knives is repeatec. three times in the circumference of the die roll, the pattern as a whole repeats only once, and a die roll of this kind may be used with others of norma. repeat length to give a wide varietv of effects. In the machine described the roll, Fig. 2, is the second of three die rolls. The first die roll lays the pattern D<1>, Fig. 5A, with three repeats d<1>, the roll, Fig. 2, adds pattern elements including S<1>, S<11>, to form the pattern D<2> with repeat length D<2>, and the third roll completes the pattern except for the squares S. In a modification, the oblong SX lies along the circumference of the die roll instead of transversely. To facilitate the cutting and rejection of pieces of scrap larger than the head of the stripper, the cutting of the mix is completed after leaving the platen 7 by a stiff brush 7a pressing it down between the knives, and a brush 19 engages the edges of the scrap as it is pushed out by the strippers.

Filed: 1966-07-27
Abstract: 1,198,625. Rotary internal combustion engines; motor power plant. J.W. MARSHALL. July 21, 1967 [July 27, 1966; April 6, 1967 (2)], Nos. 33702/66, 15779/67 and 15780/67. Headings F1F and F1Q. A rotary internal combustion engine comprises a casing 4, Fig. 1, having intersecting parallel bores within which is respectively mounted for rotation in opposite directions a male rotor 1 having as shown, cycloidal lobes 5 four in number, involute lobes and any number of lobes may be employed, and a female rotor 2 having twice as many cavities 28 as the male rotor has lobes with the rotors having close running clearance with respect to each other and to the bores to provide friction less running without lubrication. Ports 6<SP>1</SP>, 6<SP>11</SP>, in the casing end-walls 18, Fig. 3, admit air to both bores. The air admitted through the ports 6<SP>1</SP> being compressed with and mixed with fuel admitted through an injector 10 on rotation of the rotors in the direction of the arrows 29. This air also together with the air admitted through the ports 6<SP>11</SP> scavenges the bores. The compressed gaseous fuel/air mixture is ignited by glow-plugs 9, 9<SP>1</SP> in combustion chambers 69, 70 formed in a combustion chamber body 85 mounted with clearance for insulation purposes in the casing end-walls 18. The expanding gases rotate the rotors and finally exhaust through peripheral casing ports 7, 7<SP>1</SP>. The exhaust gases which leave the ports 7, 7<SP>1</SP> at high velocity and appreciable pressure may be used to drive a turbine coupled to the shaft mounting the male rotor 2 to give added torque or drive a super-charger and at the same time suppress engine noise. Instead of glow-plugs ignition may be by means of spark-plugs or the chambers may be sufficiently hot to ignite the gases in which case the glow-plugs would cut in and out automatically as required. The rotors are made of material having a low co-efficient of thermal expansion, e.g., high nickel/iron alloy known under the Registered Trade Mark, "Invar". Cooling air circulates through cavities 83 to cool the casing and excess scavenge air passes through bores 61, 84 to cool the rotors. Water may be injected into the scavenage air to assist cooling. Alternatively the bores 61, 84 may be plugged at their ends and cooling oil or other liquid coolant then passes through axial and radial holes in the rotors into and out of the bores 61, 84 and bores 90 at the tips of the female rotor 2. Labyrinth grooves at the rotor tips assist sealing of the rotors with respect to each other and the bores.
