Title: Process for the production of resins soluble in oil
IPC: C09F1/00
Filed: 1932-04-09
Abstract: Resinous compositions are prepared by introducing a resin insoluble in oil in finely divided form or dissolved in a solvent such as phenol, cresol or glycerine into a molten resin soluble in oil such as colophony or dammar and heating to dissolve the insoluble resin, solvents, if used, being eliminated.  The product may be esterified with glycerine or neutralized with a metal oxide.  The insoluble resin may be an oil-insoluble artificial resin such as a condensation product of aldehydes with phenols. In examples, (1) Congo copal in a finely divided form is blended with colophony and the product esterfied with glycerin.  (3) Finely divided Congo copal is blended with dammar resin and the product esterified with glycerine or neutralized with calcium hydroxide.  (4) Colophony is blended with a condensation product of cresol and formaldehyde made in the presence of a catalyst such as phthalic anhydride and salicylic acid and containing excess of cresol; the product may be esterified with glycerine.  (5) Cresol dissolved in glycerine is condensed with formaldehyde in the presence of a catalyst and blended with rosin.ALSO:Resinous compositions, soluble in oil, and useful for making varnishes are prepared by introducing a resin insoluble in oil in finely divided form into a molten resin soluble in oil, and heating at 260-320 DEG  C. until the insoluble resin is dissolved. Copal resins such as Congo copal, condensation products of aldehydes with phenols such as cresol-formaldehyde resin, or other natural or artificial oil-insoluble resins may be used, and the oil-soluble resin may be colophony or dammar.  Alternatively, the resin insoluble in oil may be introduced into the molten colophony or dammar as a solution in, for example, phenol, cresol or glycerine, which may be obtained in the case of phenol aldehyde resins by using excess of phenols in the condensation process; the solvent is distilled or eliminated, and the mass heated.  The acid number of the product may be lowered by heating, by esterification with a polyhydric alcohol such as glycerine, or by neutralization with a metal oxide such as lime.  Specification 367,001 is referred to.

IPC: F01L13/00
Abstract: 105,575. Thornycroft, T., and Thorny croft & Co., J. I. Jan. 20, 1916. Regulating; valves.-The invention comprises mechanism which is preferably integral and worked by the movement of a single hand-lever and will supply to the cylinders of a two-stroke-cycle engine high pressure air for starting ahead or astern, or low-pressure air for scavenging and increasing the weight of the charge or it will open communication between the two stages of the air pump so that the high pressure reservoir becomes charged. A rotary distributing-valve t controls the flow of air to the pipes y leading respectively to the head of each of the engine cylinders. The seating s of the valve is adjusted by the hand-wheel o, and it has four longitudinal passages v at angles of 90 degrees to each other leading to annular grooves w opposite the pipes y. For starting, the seating is adjusted so that a passage v is opened at the beginning of each outstroke and the valve 6 in the passage 8 from the high pressure reservoir is at the same time opened by a cam 10 on the handwheel spindle. For working with a charge of low pressure air which scavenges the combustion chamber, the seating is adjusted so as to admit these charges during the instrokes and at the same time the valve 7 in the low pressure air passage is opened by a cam 11. In another position of the wheel a cam 14 turns a bell-crank lever by which a valve is opened between the low-pressure air reservoir and the high-pressure end of the pumps.

Title: A method of and apparatus for making electrical leads
IPC: H01R43/052
Filed: 1969-02-28
Abstract: 1,207,920. Crimping electrical connectors; shearing. AMP Inc. 28 Feb., 1969 [14 March, 1968], No. 10884/69. Headings B3A, B3Q and B3W. A method of making electrical leads comprises repeatedly carrying out the steps of leading a length of wire W between open crimping dies to locate a portion of the wire for reception in a pair of axially aligned substantially U-section ferrules, crimping the ferrules to the wire portion so as to make electrical contact between the ferrules and the wire portion and concomitantly severing the wire at a position between the ferrules. The wire W is taken from a supply, via a detector 104 and guide tube 116, to pneumatically operated jaws 170 (172) mounted on a carriage 150, Fig. 8 (not shown). A strip 2 of connectors 8 is advanced by a feed finger 90 as the carriage is driven towards an adjustable stop 176. The carriage is driven along a track 12 by a piston and cylinder unit 140 until it abuts the stop 176, the location of which determines the length of wire, and actuates a micro-switch 182. Air is then supplied to a cylinder 96 to move a head 100 downwardly thereby driving the wire W against a block 102 so that a portion is positioned between the side walls 10 of a pair of connectors 8 which will form plug members. A one-shot clutch actuates a ram 26 through a working cycle and at the bottom of its stroke dies 28, 32 crimp the two connectors which are on anvils 40, 42 to the wire, a shear blade 34 severing the wire W between the two connectors and shearing a slug 16 from between the two connectors. Also, as the ram descends, the head 60 of a bolt 58 strikes shear blocks 62 and depresses them against springs 66, so that in co-operation with a shear plate 75 carrier strips 4, 6 are removed from the connectors immediately preceding the connectors on the anvils 40, 42. The shear blocks 62 and plate 75 are shaped to shear along lines A, B and to sever a connecting slug 16 along lines C. As the ram 26 is moved upwardly, the crimped connectors 8 are freed from the dies 28, 32 by stripper plates 52, 54 and the head 100 is also moved to free the wire W. The jaws on the carriage 150 are opened and the wire, which now has a connector at either end, is freed therefrom by a portion 204 of a spring- loaded plate 200, the wire falling into a receptacle 136. The unit 140 is then actuated to return the carriage 150 and at the end of the stroke, a flange 208 on the plate 200 engages a cam bar 210 to disengage the portion 204 from the jaws, Fig. 9. The carriage also actuates a micro-switch 186 to repeat the operating cycle. Should no wire be present in the detector 104, then the apparatus is automatically stopped. In an alternative embodiment when crimping spade or ring terminals an additional shear blade (218) is provided on either side of the shear blade (34a) to trim the wire adjacent the ferrules, so that loose ends of wire do not obstruct the terminal, Fig. 10 (not shown).
