Title: Improvements in the locking of screw-threaded parts
Inventor: SALLIS JOHN GRAEME MATTHEW
IPC: F16B39/34
Filed: 1957-01-14
Abstract: In a method of locking together screw-threaded components, the threads of the separate components are each coated with one of the parts of a two-part reactive resin which, on assembly of the components, react together to form a nonreactive resin that adheres to the threads or sets to a flexible condition.  The resins are those based on an epoxide compound and a catalyst or curing agent therefor, e.g. an organic base, which on mixing with the compound causes it to set into a stable condition. Preferably, a reactive epoxide resin containing approximately two epoxy radicals per molecule is used. This may be made by reacting epichlorhydrin with a polyhydroxy compound such as bis-phenol. One part of the resin may then consist of the epoxide resin base in the reactive condition, not containing any catalyst.  Resins of a suitable viscosity may be obtained by mixing solid and liquid resins or by the addition of fillers, preferably thixotropic fillers such as silica or P.V.C.  The second part of the epoxide resin can be made by reacting a reactive epoxide resin base with an excess of an organic base catalyst, e.g. diethylene triamine or ethylene diamine.  The reaction produces an adduct of the resin base and the excess catalyst, the waste products being removed. The viscosity of the adduct is adjustable by adding fillers or resins prepared by reacting dimerized vegetable oils with aliphatic polyamines.  Alternatively, a resin of the latter kind, which acts as a catalyst for the epoxide resin, can be used alone as the second part of the resin.  The threads of the members may be coated by dipping, either in the respective molten resin or in solutions of the parts of suitable viscosity.  The members may be stored before assembly.  The Specification describes the preparation of the first and second parts using commercial chemicals; the solvent used is a toluene/butanol mixture. Specifications 691,543 and 779,566 are referred to.

Title: Improvements in or relating to hot-gas, refrigerating, or heat-pump reciprocating engines
IPC: F02G1/044
Filed: 1952-01-17
Abstract: 708,199. Refrigerating. NAAMLOOZE VENNOOTSCHAP GLOEILAMPENFABRIEKEN. Jan. 17, 1952 [Jan. 20, 1951], No. 1366/52. Class 29 [Also in Group XXVII] In a hot-gas, refrigerating, or heat-pump reciprocating engine having two or more closed cycles simultaneously performed and in which each heater comprises one or more elements, shown as tubes 15, Figs. 1 and 2, each opening at one end into a hot space 12 above a piston 11 in a cylinder 1 and at the other end into a space 5 containing a regenerator 9 and cooler 10, the cylinders being disposed substantially in the form of or forming a part of an annulus, the elements together form a wall for the exchange of heat energy: -and the areas of the wall surfaces of the elements associated with each cycle are all substantially equal. The cooler communicates with a cold space below a piston (not shown) in a cylinder 2 through a passage 25. Similarly hot spaces in cylinders 2, 3, 4 communicate respectively with spaces 6, 7, 8 similar to the spaces 5. The coolers in the spaces 6, 7, 8 communicate with cold spaces below the pistons in the other cylinders. Heat is supplied by a burner 26. In a modification, spaces 13, 14 between which the heater tubes are connected are dispensed with, and the hot spaces are connected directly to the regenerator spaces by tubes with helical portions. The tubes are surrounded by ring burners. In another modification, Figs. 5 and 6, regenerators 42 and coolers 43 surround the cold spaces. Each hot space is connected through tubes comprising the heaters, a regenerator and a cooler to the associated cold space in an adjacent cylinder. Thus the hot space 12 communicates through pipes 41 and a regenerator and cooler (not shown) with a cold space below the piston in the cylinder 4. The hot space of the cylinder 4 communicates through pipes 45, a regenerator 42 and a cooler 43 with the cold space 44 of the cylinder 3 and so on. All the pipes of each group preferably have substantially equal lengths. The driving gear may comprise a swash plate mechanism or a crankshaft. Instead of having four double acting cylinders as shown, the engine may comprise two, three, or more cylinders and may be either single acting or double acting. The tubes may be arranged close together or spaced apart. The cross-section of the elments may be circular, rectangular or oval.

Patent GB-443863-A (GB)
Title: A process for the preparation of amines
Filed: 1935-01-15
Abstract: Alkylaryl amines are obtained from a -arylamino- or a -alkylarylamino-aliphatic acids, containing more than nine carbon atoms in the acid residue and not more than two carbon atoms in the alkyl group, if present, by heating the acids in an inert solvent until carbon dioxide is no longer evolved.  An example is given in which a -anilinostearic acid is heated to above 200 DEG  C. in paraffin oil to yield heptadecylaniline. Reference is made also to the treatment of a -methylanilinolauric acid.  When a -alkylarylamino acids are treated, an alkyl ester of an a -arylamino acid is obtained as a by-product, by migration of the alkyl group to the carboxylic group; this ester may be saponified, and the a -arylamino acid so obtained may be decarboxylated as described.  The starting materials are obtainable by treating the corresponding a -halogen aliphatic acids with aryl amines or mono- or di-alkylaryl amines such as mono- or di-methylaniline.  Specification 7404/10, [Class 2 (iii)], is referred to.

Title: Improvements in and relating to the manufacture of synthetic rubber
IPC: C08F36/04
Filed: 1928-01-16
Abstract: 283,841. I. G. Farbenindustrie Akt.- Ges. Jan. 15, 1927, [Convention date]. Caoutchouc, synthetic.-Hydrocarbons suitable for the manufacture of synthetic rubber, such as butadiene, isoprene, and dimethylbutadiene, are polymerized by treatment with an alkali metal, such as sodium or potassium, in an atmosphere of hydrogen, nitrogen, or carbon dioxide and in the presence of an organic hydroxy compound or ether; the quantity of organic hydroxy compound employed should not be sufficient to react with all the alkali metal present. It is preferred to use an organic hydroxy compound or ether of high molecular weight, such as starch, cellulose, a cellulose ether, or superficially oxidized rubber. The reaction mixture may include an inorganic hydroxy compound, the presence of which in the mixture may be ensured by using superficially oxidized sodium or by treating the hydrocarbon in a moist state. The reaction mixture mav include also an inert solvent, such as a hydrocarbon, which may be removed from the product to any desired extent. The polymerization may be effected in the cold or at a raised temperature, and the mass may be in motion or at rest. According to the examples, (1) isoprene, glycerine, and sodium wire are agitated together at 60‹ C. in an atmosphere of carbon dioxide until a polymerized product is obtained; (2) dried isoprene is mixed with starch and sodium and the mixture is treated as in example 1; (3) isoprene previously saturated with hydrogen is mixed with ethyl cellulose and superficially oxidized sodium and is polymerized at 40-50‹ C. in an atmosphene of hydrogen; (4) imperfectly dried isoprene containing isoprene alcohol as an impurity is treated with sodium, solid caustic soda, and benzene, and, after the mixture has been saturated with carbon dioxide, is polymerized at 60-70‹ C. in an atmosphere of carbon dioxide.

Title: Improvements in envelope making machines
IPC: B31B19/00
Filed: 1928-01-20
Abstract: 285,053. Smithe Machine Co., Inc., F. L., (Assignees of Novick, A.). Feb. 10, 1927, [Convention date]. Envelopes, making.-In an envelopemaking machine a conveyer for a band of overlapping envelope blanks is provided with means for positively holding the blanks in spaced overlapping relation and the blanks are removed from the holding means and advanced into fully-spaced relation to one another by mechanism operating in timed relation to the conveyer-operating mechanism. Blanks 19 are fed in overlapping relation over a drum 22 by conveyer chains 20 provided with spring fingers which grip the rearward parts of the blanks. The chains 20 pass around small sprockets 54, over guide wheels 101 on a shaft 100 secured to the side frames 25 of the machine, under guide wheels 103, and over sprockets 53 on a shaft 52. The shaft 52 is geared to a shaft 48 driven through a chain 46 by a shaft 44. A shaft 40 at the opposite end of the machine drives the shaft 44 through a chain 42 and is itself driven by a main shaft 28 through chain gearing (not shown). The shaft 55 of the sprockets 54 is coupled to the shaft 52 by a chain 81. A wire 146 presses the rear flaps 83 of the blanks against the drum 22. Before reaching the shaft 55 the blanks pass beneath a roller 84, adapted to engage and hold back the rear flap of the blank next to the leading blank, and on to a table 88 where a mutilated feed roller 62 driven by the chain 42 at a greater surface speed than the conveyer co-operates with a lower feed roller 63 to draw the blank from the conveyer 20 and separate it completely from the remaining blanks. The operative sector of the roller 62 is adjustable. The separated blank is fed along the table 88 by conveyer chains 111 provided with pins 122 adapted to engage the blanks in the corners between the rear flaps 83 and side flaps 123 to centre them accurately for the scoring operation. The chains 111 pass over sprockets 112 on the shaft 65 of the roller 63 and sprockets 113 on a shaft 114 secured in brackets on a crossbar 91, the shaft 114 being geared to the shaft 40 through a shaft 117. Wires 137 keep the blanks in contact with the pins 122 and the chains are positioned by guiding channels 135 having one loosely-mounted spring-pressed side adapted to avoid jamming if a blank is caught in the chains. Retarding brushes 131, 132 ensure contact between the blanks and the pins 122. The blanks are fed to scoring mechanism rotating at a greater surface speed than their own and comprising longitudinal and transverse scorers 127, 130 mounted on the shaft 117. Specifications 282,649, and 284,259, [Class 100 (i), Feeding and delivering webs &c.], are referred to.

Abstract: 837,578. Pneumatic springs. FIRESTONE TIRE & RUBBER CO. Jan. 21, 1958 [Jan. 30, 1957; Jan. 31, 1957; Feb. 1, 1957], No. 2007/58. Class 108(3) An air-spring is made by forming a cylindrical body of rubber plies, expanding the ends into frusto-conical form and turning them back about metal bead rings to form beads. The spring is then moulded and vulcanized in its final shape. A drum 20, Fig. 1, over which the plies are laid is in two parts 21, 22. Chucks 33, 34 hold the bead rings and mandrels 31, 32 expand the ends of the plies. Sleeves 35, 36 turn the ends of the plies about the beads. To load the bead rings into chucks 33, 34 drum sections 21, 22 are moved apart and the chucks moved inwards. The drum sections are now moved together through the bead rings and the chucks moved outwards. The rubber plies are laid on the drum to form a cylindrical body 20. Next the bead ring chucks 33, 34 are positioned over the ends of the cylinder 20, with the bead rings aligned with circumferential ring engaging grooves in the drum sections. Fig. 5 shows the ends of cylinder 20 expanded by mandrels 31, 32 into engagement with bead rings 13, 14. One end of the cylinder 20 is turned back over the bead ring by a key-turning sleeve 35. The ends of the cylinder are stitched in position over the bead-rings Finally an outer cover of gum rubber is applied to the body of the air spring. Mandrels 31, 32 expand the plies at the ends of the air spring by forcing outwards segments which are pivoted in slots in the ends of the drum sections. Each chuck comprises radially movable grooved rollers 120, Fig. 18, mounted on pins 121 held by annular members 122, 123, Fig. 17. Rollers 120 are moved in and out to grip the bead ring by rotating member 128 with respect to members 122, 123 by moving arm 135, Fig. 18, up and down. This causes slots 129 in member 128 to act as cams and force pins 121 to slide radially in slots 124 moving rollers 120 with them. Specifications 807,535 and 819,728 are referred to.
