Title: New printing inks for uncoated paper stock
IPC: C09D11/02
Filed: 1964-06-19
Abstract: Typographic printing inks comprise pigment dispersed in a non-aqueous medium comprising ethylene glycol, a dissolved water-insoluble acidic resin of acid number at least 100, and urea.  In the preparation of the medium a resin of high acid number may be used and the medium heated to effect a 10 to 50% reduction thereof before adding the pigment.  The ink may contain a water-soluble C3-8 glycol, a polyglycol, or a mono-alkyl ether thereof as co-solvent and various surfactants. Specified resins are various rosins and modified rosins and terpene and alkyd resins.  They may be imine modified, e.g. with C2 or C3 alkylene imines or trialkylene phosphoramide or thiophosphoramide, or partially amidated with diamines or C2 or C3 alkanolamines.ALSO:Typographic printing inks comprise pigment dispersed in a non-aqueous medium comprising ethylene glycol, a dissolved water-insoluble acidic resin of acid number at least 100, and urea.

[Also in Division C3] Electrotype printing plates are produced by bonding a metal electrotype shell, at 250 to 525 F. and 10 to 80 p.s.i. pressure, to a resin composition comprising: (1) 60 to 90 parts by weight of a thermoplastic polyhydroxyether [-D-O-E-O-] n  wherein D is the residue of a dihydric phenol, E is an hydroxyl-containing residue of an epoxide, and n is at least 30; (2) 5 to 30 parts by weight of an elastomer; and (3) 5 to 30 parts by weight of a primary plasticizer which is a dialkyl phthalate, a dialkyl ester of a dibasic aliphatic acid of 6 to 10 carbon atoms a triaryl phosphate, an alkaryl phosphate or a trialkyl phosphate. The polyhydroxy ether is preferably formed from epichlorhydrin and 2,2 bis-(4-hydroxyphenyl)propane; the elastomer is preferably a polyurethane formed as a block copolymer from bis-(4-isocyanatophenyl)methane and poly (1,4-butyleneadipate)hydroxyl-terminated with 1,4-butanediol, although other polyurethanes and butadiene rubbers are also specified. The preferred plasticizer is dibutyl phthalate. The resin composition is generally applied to a surface-oxidized copper electrotype shell, and the thus completed plate may be laminated to an aluminium printing press saddle.

[Also in Division H2] A push-pull oscillator or switching circuit, particularly for providing power for an A.C. motor, is provided with means for protection against both switching devices becoming conductive simultaneously. As shown in Fig. 1 (not shown), an A.C. motor has a main stator winding 14, a rotor winding 20, a starting winding 16 and a feedback winding 28 arranged so as to permit electronic switches such as transistors or semi-conductor controlled rectifiers 10, 12 to act as a self-oscillating circuit. Switches 10, 12 become conductive alternately so as to connect the D.C. supply 34 alternately to points A, C of the stator winding 14. In the event of excess load on the motor causing both switches 10, 12 to become simultaneously conductive, relay R becomes energized, disconnecting the supply 34 for a period depending on the discharge time of capacitor 48. In Fig. 2, switches 10, 12 are driven by an external oscillator.

Abstract: 169,382. Ireland, A. J. T. Sept. 9, 1920. Screw propellers.-Relates to the blades of propellers, windmills, fans, &c. which are pivotally and adjustably secured to the hub, and consists in attaching the blades by pins which lie parallel to the hub axis, the pins passing through holes in lugs on the hub and in lugs on the blade roots or attachments thereto, the blades being further held by dogs, teeth, &c. in a casing on or attached to the hub. The hub, Fig. 1, has lugs or collars 4 connected by an anchoring nin 9 with lugs 8 in a cap 7 which passes around the blade socket 5 and has a spigot 13 which passes through blade base 19. The cap is secured to the socket by a bridge-piece 18 held by the nut 14. The outer casing is in two parts 11, 12 secured to the hub by ring nuts 22, 24, the flanges being held together by bolts 26. Each half casing is enlarged at 25 to take the blade sockets, the enlargements being reinforced by webs 28 and flanges 27. In a modification, a simple bifurcated eye-bolt may be used and the blade root guided by an internal ring on the casing parallel to the flanges 27. When no pitch adjustment is desired. the bifurcated lugs may be attached directly to the blade root. When the casing is in one piece, openings 30 are provided for giving access to the anchoring-pin. The inner walls of the casing sockets are serrated or toothed at 31 to engage corresponding parts 32 on the blade roots for the purposing of maintaining or setting the blades at the desired pitch. For altering the pitch, the two-part casing may be separated, or the blades withdrawn radially, and in the latter method this can be effected without disconnecting the anchoring pin if a spring is fitted between the blade root and the anchoring- pin.

Title: Improvements in and relating to crimping apparatus
IPC: B21F15/00
Filed: 1969-05-27
Abstract: 1,211,666. Making electrical components; jointing by stamping. AMP Inc. 27 May, 1969 [19 June, 1968], No. 26650/69. Headings B3A and B3Q. Apparatus for crimping electrical connectors 14 to the ends of wires, each connector, prior to crimping, being secured to a carrier belt 2, comprises a pair of crimping dies 186, 188 and 176, 178 relatively movable from a first open position to a second closed crimping position, means 74 for feeding the carrier belt 2 intermittently along a predetermined path to position successive leading connectors secured to the belt 2 between the dies when in their first open position, and means for moving the carrier belt laterally of the feed path when the dies are in their second closed crimping position after crimping the leading connector to a wire end, to separate the crimped connector 10 from the carrier belt 2. A feed support block 72 is slidably mounted on a fixed block 160 and is moved to the right as seen in Fig. 5 by means of a connecting rod 148 which is pivotally mounted between ears 144 on a bracket 146 and which extends through an opening in a frame section 24. The right hand end of the connecting rod 148 is pivotally connected at 150 to a lever 152 which extends upwardly and is pivoted to a bracket 153 fixed to the frame. The upper end of the lever 152 has a cam roller 154 which is engaged by a cam plate 156 mounted on the periphery of an eccentric plate 48 secured to a shaft 50. Thus during each complete revolution of the shaft 50, the cam plate 156 will cause, via the lever 152 and connecting rod 148, the feed mechanism support block 72 to move to the right as seen in Fig. 5. A retaining plate 138 is mounted on the support block 72 and is also moved to the right. In operation, the stripped end 16 of a wire is inserted into the terminal 10 and a clutch 52 engaged to drive plate 48 through a single revolution. During the initial portion of the stroke, the ram 32 moves relatively downwards until lost motion between the ram and a die holding block 192 is taken out. Thereafter the ram 32 moves a further portion of its downward stroke to crimp the terminal 10 on to the wire. During this interval, and while the crimped terminal is being held between the dies, the connecting rod 148 is moved to the right as described above thus pulling the belt 2 away from the terminal 10. The block 72 then returns to its starting position and the ram 32 moves upwardly. An ejector arm 228 then ejects the completed terminal from the crimping zone and the belt feed mechanism is actuated by connecting rod 104 to advance the belt 2 and position an uncrimped terminal between the dies. During the final portion of the cycle, the ram descends partially until the dies surround the uncrimped terminal.
