Title: Improvements relating to machines for testing or forming gears
IPC: B23F23/06
Filed: 1954-07-22
Abstract: 778,291. Chucks. GLEASON WORKS. July 22, 1954 [Aug. 3, 1953], No. 34795/55. Divided out of 778,290, [Group XXIII]. Class 83 (3). A machine for forming or testing gears comprises chuck-means, including a draw-rod 88, extending through the spindle to secure a gear thereon, and a pair of elements 107, 108, movable as a unit axially of the spindle to engage abutments 99a, 105 connected to the spindle and rod to move the rod axially. The spindle 24 runs in bearings, the races 74, 75 of which are engaged by sleeves 77, 79 screwed together. The bearings can be preloaded by rotating an eccentric-pin 81 which turns the sleeve 79. The gear P is held against an arbor 84 by a rod 85 gripped in a collet 86 urged rearwardly by springs 92 within a pulley 99. To release the gear, the spring-pressure is relieved by rotation of a handle 93. The collet is adjusted axially by a screwed-bush 94 and the spring-pressure is adjusted by a bush 95. To prevent the force of the springs 92 being transmitted to the bearings, rotation of the handle 93 initially moves a sleeve 107 rearwardly against the force of a spring 114. When the sleeve has engaged a flange 99a on the spindle, continued rotation of the handle 93 presses a flange 111 against the pin 105 connected, by members 96, 94, to the rod 88 to move it forwardly. Rotation of the handle 93 to unclamping position is limited by engagement of dogs 115. A thermoplastic plunger 116 engages the rotatable clamping- parts to deaden vibration.

Title: Improvements in the condensation of aromatic compounds with olefinic compounds
IPC: C07C2/66
Filed: 1928-11-28
Abstract: 327,382. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 28, 1928. Hydrocarbons and heterocyclic compounds, and derivatives thereof.-Olefinic compounds are condensed with aromatic, or partly, or completely hydrogenated aromatic hydrocarbons or derivatives thereof, or aliphatic saturated compounds, in the presence of a catalyst containing a metal meta- or pyro-phosphate, -borate, or - arsenate which is difficultly reduced by hydrogen at the temperatures employed. Particularly suitable catalysts are salts, according to the above definition, of di- or tri-valent metals such as zinc, chromium, manganese, or earth metals such as cerium and aluminium, and these may contain a small amount of the free acid. The condensations are preferably carried out at superatmospheric pressure and at temperatures from about 200‹ to 500‹ C. In the examples in which cerium metaphosphate is used as catalyst, condensation is effected between (1) naphthalene and ethylene, (2) toluene and butylene, (3) dekahydronaphthalene and ethylene, (4) styrene and naphthalene, the pressure being maintained in this latter case by supplying nitrogen to the autoclave until a pressure of 30 atmospheres is obtained. In each of the above examples, the product is of an oily nature and may constitute a very viscous lubricating oil. Further examples are given in which the catalysts used are cerium aluminium metaphosphate, chromium metaphosphate, cerium metaborate, and aluminium meta- or pyroarsenate. Other examples are given in which (1) aniline is condensed with ethylene to give substituted anilines together with tertiary bases containing heterocyclically combined nitrogen, (2) p-chlorethylbenzene is obtained from monochlorbenzene and ethylene, (3) substituted phenols are obtained by condensing phenols with ethylene. In an example in which ethylene is condensed with stearic glyceride, the product contains low fatty acids due to the breaking down of the complex molecules produced by condensation. Specification 311,899 is referred to.

Title: Hydraulic devices
IPC: F15B11/22
Filed: 1972-07-28
Abstract: 1391126 Hydraulic reciprocating motors FABBRICA ITALIANA MAGNETI MARELLI SpA 28 July 1972 [31 July 1971] 35454/72 Heading F1A Pistons 12,72 of a device for oscillating vehicle windscreen wipers (not shown) are reciprocated in synchronism in cylinders 10,72 by liquid alternately supplied to working chambers M 1 ,M p2  by a distributor valve T, the changeover of the valve T being controlled by a device K responsive to the fall of pressure in the opposed working chambers M 2 ,M P1  which occurs when one or other of relief valves 22,84 is opened by a respective pin 26,88 at the end of each working stroke. In the position of the device shown, the pistons are completing their rightward strokes under the action of liquid directed by the valve T to the chamber M 1 , the liquid being supplied to the valve T from a source Ma via a stop valve R 1  and a throttling valve D. When the pin 88 opens the valve 84, liquid in the chambers M 2 ,MP 1  and a connecting conduit 104 are connected to an outlet Sc via passages 76,78,80 in the piston 72. The resulting fall in pressure in the conduit 104 is detected in a chamber K2 of the pressure responsive device K the chamber being partly defined by a diaphragm 124. A spring 126 thus moves the diaphragm and a rod 135, thereby to effect, via a toggle mechanism 138, 140 leftward movement of the valve T. This causes the pressurization of chamber M P2  and the exhaust, via a check valve V 1 , of chamber M 1 . A return stroke is therefore initiated provided a pin 28 is in the position shown. If, on the contrary, the pin 28 displaced to the left by moving a valve R 2  to a position in which liquid causes operation of an actuator piston 150, the consequentially increased opening of a relief valve 24 prevents pressure building up in the chamber M P2  and the pistons remain in their positions shown. In a second embodiment, Fig.1 (not shown), the pressure responsive device (B) controls a valve member (32) which operates in conjunction with a piston actuated commutator valve C to cause hydraulic changeover of the distributor valve T. Two by-pass passages around a valve (R 2 ) for stopping the device by cutting off the liquid supply are under the control, respectively, of a valve (34) operated by the pressure responsive device (B) and a valve land (42) of the commutator valve (C).
