Abstract: 532,532. Synthetic resin compositions. INTERCHEMICAL CORPORATION. July 24, 1939, Nos. 21466 and 21467. Convention dates, April 12 and July 11. [Class 2 (iii)] A heat-convertible synthetic resin composition which does not discolour at high temperatures comprises a urea-formaldehyde resin soluble in organic solvents and a heat-convertible alkyd resin consisting of the reaction product of a polyhydric alcohol, phthalic acid and one or more of lauric, myristic and palmitic acids, which acids are substantially free from unsaturated fatty compounds and containing less than 10 per cent. of other saturated acid. The fatty acid constitutes 20-60 per cent. of the alkyd resin and the ratio of alkyd to urea resin is between 1:5 and 5:1. Phthalic acid may be replaced by other dibasic acids up to a few per cent. To avoid discoloration, the urea resin should be prepared from formaldehyde and urea or urea derivatives other than thiourea and other discolouring derivatives, and the finished composition should be substantially free from non-volatile fatty acid compounds. Examples are given of the preparation of (1) a urea resin by heating together formaldehyde and phosphoric acid, adding urea in stages at 60-65‹C., then raising the temperature to 85-90‹C. and, after a time adding n-butanol and mildly refluxing at 90-95‹C. and finally distilling off water and butanol and adjusting the solution to a 50 per cent. non-volatile content; (2)-(6) alkyd resins from phthalic anhydride, glycerine and lauric (2 and 3), myristic (4 and 5) and palmitic (6) acids by heating to 450‹F. in an aluminium kettle in an atmosphere of carbon dioxide ; (7) a coating composition by mixing the urea resin solution of (1) with a xylol solution of (2) and titanium oxide, which composition may be sprayed on metal and baked for 30 minutes at 250 F. or 10 minutes at 350 F., and (8) and (9) moulding compositions by blending the urea resin, preferably with some of the solvent removed, with the solid alkyd resin on a two-roller mill to produce a powder which can be moulded at 350‹F. under a pressure of 2,000 lb. per sq. inch for 10 minutes.

Filed: 1962-06-05
Abstract: 964,457. Foundry plant. HERMAN PNEUMATIC MACHINE CO. June 5, 1962 [June 19, 1961; Aug. 11, 1961 (2)], No. 21630/62. Heading B3F. Moulds are formed in flasks at one station of a foundry apparatus and are then fed alternately one at a time or in batteries to at least two casting stations, the casting steps at the respective casting stations being staggered in time so that flasks with moulds and castings therein are delivered at approximately uniform intervals alternately from the respective casting stations. Flasks for pipe moulds are gravity fed into a holder 17 at station A which supports a battery of four flasks at a time. The holder is rotatable so that the flasks may be up-ended over vertically movable formers 20 which form elongated cavities in moulding material introduced into the flasks, as described in Application 21628/62. At station B, if desired, the flasks are lowered on to driven rolls 33 which rotate them while the sand is further compacted by mandrels 36 introduced into the moulds, as described in Specification 650,683, which is referred to. At station C, if necessary, cores are introduced into the moulds. Station D is a transfer zone, at which the batteries of flasks are received on a transversely movable car 54 which directs them alternately to the casting stations X, Y which lie on opposite sides of the centre line of the apparatus, each having centrifuging rolls 64, Fig. 3, for the centrifugal casting of metal supplied through funnels 67. From the casting machines the batteries of flasks are fed alternately to a transversely movable car 70 at station F which transports them to the centreline of the apparatus to rails 69, from which they travel to station G, whereat the castings are ejected by rams 74. From the stripper station the flasks roll to an elevator 79 which lifts them to a top conveyer run 84 which carries them to an elevator 4 which lowers them for feeding them into the moulding station A for another cycle. The flasks are moved between the stations B, C, D and F and G by reciprocating trucks 42, 43, coupled together on central rails 41 and having fingers 50, 50<SP>1</SP> which are movable to positions to engage the flasks, and inoperative positions during return strokes. Similar trucks 61, Fig. 3, move the flasks from the car 54 to the casting machines and from the casting machines on to the car 70.

Title: Production of shaped elastomeric articles from polyurethane reaction products
Inventor: JONES FREDERICK ARTHUR
IPC: C08G18/42
Filed: 1955-07-28
Abstract: Shaped elastomeric products are obtained from a mixture of a solid comminuted reaction product of a polyether, polyester or polyesteramide with an organic polyisocyanate or polyisothiocyanate, together with a plastic reaction product of the same kind in which solidification has been retarded by incorporation of an acid stabilizing agent, by neutralizing the stabilizing agent, shaping the mixture and converting it to the elastomeric state.  The solid and plastic reaction products may be mixed on conventional rubber-processing machinery.  Suitable acid stabilizing agents are organic acid chlorides; acid esters of phosphorus-containing acids and oxyacids of phosphorus (see Specifications 790,543, 791,956 and 831,301).  Preferably, the two reaction products are milled together if desired with additional diisocyanate.  Fillers, e.g. carbon black, silica may also be added at this stage.  The stabilizer is then neutralized by addition of a base, preferably in solid form, e.g. diphenylamine, p-phenylenediamine, guanidine, aniline, aminopyridine, 2,2-dipyridylamine, 2 - amino - 4,6 - dimethylpyridine, urea, hexamethylene tetramine, hydrazine hydrate, magnesium oxide, calcium hydroxide or ammonium carbonate.  The product is shaped, e.g. by pressing and then moulded under pressure.  In Example (1) polyethylene glycol adipate (M.W. about 2000) was reacted with naphthalene 1,5-diisocyanate and a little water to produce a coarse dry crumb which is mechanically disintegrated.  The product was milled into the reaction product of polyethylene glycol adipate, naphthalene 1,5-diisocyanate and a little butane 1,4-diol, stabilized with p-nitro-benzoylchloride.  Diphenylamine was added during milling and the sheet separated into two parts, one which was moulded alone while the other was moulded after admixture with carbon black. Alternative stabilizing agents are stearoyl chloride, butyl acid phosphate, o-nitrobenzenesulphenyl chloride, and orthophosphoric acid.

Title: Torque nut runner with motor brake
IPC: B25B23/145
Filed: 1967-05-11
Abstract: 1,136,810. Nut-runners. CHICAGO PNEUMATIC TOOL CO. 11 May, 1967 [16 Aug., 1966], No. 21969/67. Heading B3N. A nut-runner comprises a slidable-vane pneumatic motor 11, Figs. 1, 1A, which drives an output spindle 24 through a reduction gearing 12 and a clutch 14, 15, a reversing valve 30, a shut-off valve 45 and a control valve 56, being provided for braking the motor, and driving it in the reverse direction sufficiently to re-engage the clutch, when a predetermined tightening torque is reached. Clutch 14, 15 comprises rollers 16 carried by member 14 which co-operate with pockets on the face of member 15, and the latter is urged to engage the rollers by a spring 21. A stationary bushing 27 has ports 28, 32 which connect through passages 29 and 33 with the motor chamber 31, and a port 34 which connects with venting passsages. Valve 30 is slidable in bushing 27 and is urged upwardly by a spring 42. Shut-off valve 45 is slidable in valve 30 which carries a valve seat 46, and it is connected to rods, 52 and 48. Control valve 56 is slidable on rod 48 and co-operates with a seat 43. In operation, air enters an inlet 25 and flows into valve 30 but is prevented from flowing through a port 47 leading to the motor chamber by valve 45. Air also flows around valve 30 through port 28 and passages 29, to the motor chamber, causing the motor to rotate. Torque is transmitted to the work until a predetermined value is reached, whereupon rollers 16 ride up out of the pockets in member 15 which is moved downwardly, thus allowing a spring 45 to move rods 52, 48 and shut off valve 45 in the same direction. Valve 45 engages valve 56 which opens and vents a counter balancing chamber 58. Valve 30 moves downwardly, ports 28 and 34 are connected, and port 28 is blocked off from inlet chamber 26. The latter is placed in communication, through the interiors of valves 30 and 45, with a port 47 connected through port 32 and passages 33 with the motor chamber, so that a torque in the reverse direction is applied to the motor which is thus momentarily braked. Clutch spring 21 re-engages the clutch members so that rollers 16 move back into the pockets on the face of member 15 and a brief reverse rotation is imparted to the motor. Rods 48, 52 are moved upwardly and the valves are returned to their previous positions, ready for the next cycle.

As described a polygonal roller 1 is rotatably mounted on a frame 2, pivoted at 3 and adapted to be oscillated towards and away from the pressing member 22 by a piston-rod 4. The frame 2 supports a slidable rod 10 having at one end a roller 11 engaged in a cam track 12. A pawl 13 on the rod 10 engages pins 15 on the roller 1 to rotate the latter, and a pawl 14 on the rod 10 engages a lever 16 carrying the knife 18 to cause it to enter one of a number of slots 6 in the roller 1 to sever the tape. In operation tape 21 is fed over a roller 20 and held against the surface of roller 1 by suction. As the piston-rod 4 is advanced the rod 10 slides to the right to cause the knife 18 to cut the tape, and then a cut length of tape is pressed against the web 23. The rod 4 is then retracted to cause rotation of the roller 1 by the pawl 13 and thus drawing forward of a further tape length. The pressing member 22 or the roller 1 may be provided with a heat-sealing element, e.g. a resistance heater tape. The roller may be circular, the pressing member in this case having an arcuate surface.
