Title: Hydraulically-operated tracer assembly for engine lathes
IPC: B23Q35/36
Filed: 1962-04-03
Abstract: 961,360. Copying lathes. TYDEMAN MACHINE WORKS Inc. April 3, 1962 [April 6, 1961], No. 12786/62. Headings B3B and B3T. A tracer unit for use on a lathe to control the movement of a lathe tool in accordance with the profile of a template comprises an hydraulic cylinder 28 with piston 100 and quill 26 reciprocably mounted therein, the end of the quill carrying cutting tool 24. The movement of the quill is controlled by an hydraulic valve unit 32 carrying a spring- biased stylus 34 which follows the form of the template 18. The template is adjustably supported on a bridge assembly 16 secured to the lathe bed 14, the adjusting means including transverse and longitudinal micrometer units 68 and 86 respectively to facilitate accurate positioning thereof. The control valve unit 32 is supplied with hydraulic fluid from a constant pressure pump 36 via feed and return lines 38 and 40 respectively. Fluid enters the valve via inlet port 216 and passes into bore 202 which houses a reciprocatable spool 204 which provides the operative connection between the stylus 34 and tool 24 such that the former controls the movements of the latter. Valve unit 32 is supported on a bridge 176 which is carried by members 152 and 154, and through which interconnecting fluid passages permit the fluid movement from the valve unit 32 to either side of the piston 100. The accuracy of the reproductive movement between stylus and tool is chiefly dependent on the dimensional accuracy of the spool 204. A hand-operated retraction assembly 206 is provided in the valve unit which permits the withdrawing of the spool valve so that fluid may be delivered to the front end of the cylinder 28 to withdraw the tool 24 from the workpiece 22. The cutting tool 24 is mounted in a cylindrical tool-holder 138 located in a cylindrically-shaped opening at the forward end of the quill 28 said opening encompassing about 270 degrees to permit side adjustment of the tool within an arc of about 90 degrees. Vertical adjustment of the tool is effected by a knurled ring 136 with an eccentric opening, to receive the tool holder and a stop pin 134 the height of which may be adjusted thereby adjusting the tool height. When the stylus following the template form moves to the left, from the inoperative position, as shown in Fig. 4, the movement is transmitted to the spool 204 which in moving to the left permits fluid under pressure to flow through annular cavity 244 to annular groove 236 to passage 184 and via interconnected passages in the bridge and support members to the right-hand side of the piston 100 which subsequently moves the cutting tool to the right in an identical movement of the stylus. Similar operation is effected for right-hand movement of the valve assembly.

The pointer 2 indicates increments of a 100 feet of altitude, further pointers 23, 30 driven from the shaft 3 by a gear wheel 19, pinion 20 gear wheel 21 and shaft 22 and by a gear wheel 25, pinion 26, gear wheel 27 and a shaft 28 respectively indicate increments of 1000 feet and 10000 feet. A hatched area 31 on dial 0 is fully exposed by a cut-out portion 32 in a disc 29 moved with the pointer 30 when the aircraft is at zero feet. Rotation of a knob 34 results in movement of a gear wheel 33 and consequently via gear mechanism 14, 15, 16 shaft 3 and hence pointer 2 so that the visual altitude reading will be changed to compensate for variations in barometric pressure without corresponding change in the encoder output. A dial 40 is also controlled by the knob 34, the reading on the dial being viewed via a slit 43 in dial O. Capsule drift is compensated for by adjustment of a screw (44), Fig. 2 (not shown) to vary the pressure exerted on the capsule by a spring (45). This results in the position of both the encoder disc 13 and a pointer 2 being adjusted. As described the disc 13 has opaque and non- opaque sections illuminated from a lamp assembly. Alignment marks on the disc facilitate relative positioning of photo-cells 49 and the tracks of the disc. An additional track compensates for variations of light intensity by varying the electronic reference level. A slide 46 is operated by a solenoid 51 in the event of failure in the lamp and encoding system.

Abstract: 684,234. Feeding webs; rollers, collapsable. SARGROVE ELECTRONICS, Ltd., SARGROVE, J. A., BLAISE, R. E., BUXTON, D. H., and PILLINER, B. J. Aug. 16, 1950 [May 16, 1949], No. 12994/49. Class 100 (i). [Also in Group XXXV] In a system for automatically controlling the feed of web material, the effective diameter of a feed roller is variable in accordance with the size of a loop in the web. In a web feeding device wherein the extent of a loop 10, Fig. 1, in the web fed to the machine 12 is maintained substantially constant, the size of the loop is detected by photo-electric apparatus 13, 14 which operates an associated amplifier 15 to control the effective diameter of a feed roll 16. As shown in Fig. 2 one form of feed roll comprises a pair of coned supports 20, 21 mounted on a shaft 23 and supporting a series of supports 24 for a cylindrical surface 25 of rubber or like material. A flanged ring 26 operated by an electromagnet, or hydraulic or pneumatic means under the control of amplifier 15 causes the supports 24 to move along the coned supports 20, 21 and thus vary the diameter of the roll. In a modification which provides only for two diameters of roll the coned surfaces may face in opposite directions and variation of the roll diameter be effected from within the roll by an electromagnet or a Bowden cable. In a further modification, the coned surfaces may be dispensed with and the members 24 operated by inflatable envelopes disposed within the roll. In another arrangement, a series of resilient members forming the roll are compressed axially to expand them diametrically.

Abstract: 559,515. Discharge converters. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Oct. 14, 1941, No. 13228. Drawings to Specification. [Class 39 (i)] The anodes of converters are treated to minimize back-ignition by subjecting them to a glow discharge in a gaseous medium under constant conditions of pressure and current density, until the occurrence of back ignition as indicated by a device responsive thereto has ceased for a time sufficient to ensure that further back ignitions are not to be expected under the conditions of the treatment. The current density and voltage conditions during the forming operation are in excess of those occurring in the normal working for which the converter is rated. The gas filling may be any of the rare gases, nitrogen, hydrogen, oxygen, or mercury vapour, or mixtures thereof. and the pressure not less than 0.3 m.m. of mercury. The anodes treated may be of graphite, or more homogeneous composition such as mixtures of carbon graphite or carbides which have been sintered or baked together with bonding agents such as clay or bituminous substances ; the treatment may also be applied to aluminium or carbonized nickel anodes. Alternating or direct current may be used, and the treatment may be applied in the envelope of the rectifier, or in a separate envelope. The gas pressure may be reduced by utilizing a magnetic field to lengthen the path of the electrons and so increase the degree of ionization and the intensity of the glow discharge current, as described in Specification 488,886. The glow discharge may be used simultaneously with an arc discharge. The subjectmatter is identical with that of Specification 601,870, [Group XL (a)].

Patent GB-654772-A (GB)
Title: A process for the production of alkyl pyridines
Filed: 1948-05-18
Abstract: Alkyl pyridines are made by reacting a straight-chain alpha-beta-unsaturated aliphatic aldehyde with ammonia at 200-500 DEG , preferably 300-400 DEG  C., in the presence of a compound of boron and phosphorus, preferably boron phosphate, as catalyst.  Preferably a molecular excess of ammonia is maintained, ratios quoted being 0.5-20, preferably 5-15.  Aldehydes specified are acrolein, crotonaldehyde, 2-pentene-al-1, 2-hexene-al-1 and 2-heptene-al-1. Diluents, e.g. nitrogen, steam and hydrocarbons such as methane and hexane may be present. Atmospheric or superatmospheric pressure may be used, and throughput rates quoted are 1-150, preferably 25-75, mols. of reactants per litre of catalyst per hour.  The catalysts may be on conventional supports which may themselves have some activity. They are preferably preconditioned by treatment with ammonia at 300-400 DEG , preferably 325-375 DEG  C., and may be reactivated by heating with a gas containing free molecular oxygen at 300-500 DEG C.  In examples: (1) acrolein and ammonia are reacted at 360 DEG  C. over a preconditioned boron phosphate catalyst to yield beta-picoline with some pyridine and high-boiling pyridine bases; and in (2) acrolein and ammonia are reacted in a series of runs in the presence of boron phosphate and conventional dehydration catalysts at temperatures varying from 350-385 DEG  C., and the effectiveness of boron phosphate illustrated in a table.  In the Specification as open to inspection under Sect. 91 the aldehydes are reacted with ammonia and/or primary amines.  Primary amines specified include, methyl-, isobutyl-, amyl-, methylcyclopentyl- and cyclohexylamine.  The hydrocarbon diluents may also be converted during the course of the reaction.  This subject-matter does not appear in the Specification as accepted.ALSO:Compounds containing both boron and phosphorus are catalysts in the production of alkyl pyridines from straight-chain alpha-beta - unsaturated aliphatic aldehydes and ammonia (see Group IV (b)). The catalyst may be mixed with conventional inert diluents or with substances such as absorptive siliceous and aluminous materials which themselves may possess catalytic activity.  Boron phosphate is made by treating powdered boric acid with 85 per cent phosphoric acid to give a gelatinous substance which after standing for 20 hours is dried at 110 DEG  C., baked for 4 hours at 350 DEG C., and then crushed and screened for use as catalyst.
