Title: Improvement in a method of machining materials
IPC: G05B19/04
Filed: 1927-09-28
Abstract: 278,364. Schenker, M. Oct. 1, 1926, [Convention date]. Turning.-In a method of performing machining operations such as turning, planing, milling, grinding, drilling, and the like, the movements of the tool relative to the work are automatically controlled by means of an exchangeable key or templet which is provided with perforations located in accordance with the dimensions of the particular workpiece to be produced. In the application to a turning-lathe, the driving pulley 4 is connected through gearing 9 and countershaft 11 to a shaft 12 which is adapted to be driven in opposite directions by wheels 13, 16 respectively on the countershaft. The direction of rotation of the shaft 12 is controlled by electromagnet clutches 19, 20. The shaft 12 drives through worm gearing 21, cross shaft 22, electromagnet clutch 24, and spur gearing 26, the rack and pinion gearing 27 operating the traversing feed of the saddle 6, while further gearing 31 from the shaft 22 is controlled by an electromagnetic clutch 29 to operate the screw-and-nut mechanism 33 for the surfacing feed. The controlling key or templet 39 is mounted on a table 38 which is moved longitudinally by a gear train 34 - - 37 driven from the wheel 18 on the shaft 12. The templet is provided with slots coacting with a series of levers 41 - - 44, whose upper ends actuate contact pieces 45 - - 48, the arrangement being such that when one of the levers drops into a slot, the circuits of selected electromagnetic clutches are completed so as to start the required feed motion, the feed continuing until the end of the slot is reached. The gearing may be so arranged that the length of the feed is the same as the length of the corresponding slot in the templet. By increasing the number of levers and clutches change-speed motions or turret tool-boxes may be controlled. For producing different work-pieces the key 39 is exchanged for another key having a different combination of slots. Preferably the edge of the tool 51 is first set beneath a reference mark 63 on the machine, the position of this mark with respect to the lathe centre being accurately known. The tool displacements required to commence operations on a work piece Wand to turn up a number of portions to required diameters may then be determined and the size and location of the slots which must be cut in the templet can thus be found. In a modification the feed clutches may be controlled mechanically instead of electromagnetically. The Specification as open to inspection under Sect. 91 (3) (a) states also that the invention is applicable to the machining of stone. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,141,584. Automatic control of rolling. GOSUDARSTVENNY PROEKTNY INSTITUT TYAZHRPOMELEK-TROPROEKT. June 6, 1967, No. 26040/ 67. Heading G3R. The pressure between the rolls of the last stand of a multi-stand strip metal rolling mill is maintained constant by automatic control of roll speed at the last stand tension in the metal prior to its passage through the last stand being maintained between limits by automatically controlling screwdown at an earlier stand at intervals, and the gain of the roll speed control system being automatically reduced when tension approaches either limit. As shown, a signal derived from a pressure transducer 7 associated with rolls 3, 4 of the final stand 1 of a continuous hot strip rolling mill is compared with a reference signal from a source 8 and any error is eliminated by applying the difference to adjust a speed controller 9 for a roll driving motor 5. This varies the tension in the strip between stands 1 and 6 and deviations beyond predetermined limits are detected by a tension transducer 10 which restores tension between the limits by operating a screwdown motor 12 associated with stand 6 at intervals sufficient to allow passage of the strip from stand 6 to stand 1 between adjustments. When tension approaches either limit, the signal from tension transducer 10 also reduces the gain of speed controller 9, to zero at the limit, until tension is restored between limits again, thereby avoiding excessive variations of speed.

Title: Resol resins
Inventor: FRASER DONALD ALEXANDER
IPC: C08G8/08
Filed: 1954-09-10
Abstract: A resol resin is made by condensing a molar excess of phenolic material with formaldehyde in the presence of a salt of a divalent electropositive metal with an organic acid, said salt being at least partially soluble in the reaction mixture, at a pH of from 4 to 7 to produce a non-heat-hardenable novolak resin which is reacted with formaldehyde in the liquid phase, in the presence of alkali at a pH greater than 7, and stopping the condensation before the resol resin becomes insoluble.  The molar ratio of condensed formaldehyde to phenolic material in the final produce exceeds 1 : 1.  The phenolic material comprises phenol, meta-cresol, metaethyl phenol and mixtures thereof with or without other phenolic compounds.  Specified metal salts comprise the benzoates, formates, acetates and lactates of barium, strontium, calcium, manganese, magnesium, zinc, cadmium, cobaltous cobalt and lead.  Specified alkalies are the alkali metal hydroxides and carbonates, alkaline earth metal oxides and hydroxides, ammonia and organic bases.  In the examples: (1) and (2) excess of phenol is refluxed with formalin in presence of zinc acetate, excess phenol being distilled off, the resultant novolak being condensed with formalin in the presence of sodium hydroxide; (3) excess of mixed cresols is refluxed with formalin and zinc acetate, excess cresol being distilled off and the resultant novolak condensed with formalin in the presence of ammonia.

Abstract: 1351185 Radio navigation DYNELL ELECTRONICS CORP 19 April 1971 [7 May 1970 (2)] 26307/71 Heading H4D In a receiver, responsive to a plurality of received signals of predetermined frequency each of which is transmitted from a different location for a discrete period of time, there is generated a signal, an output representing the phase difference between each received signal and the generated signal is produced and a register means controlled by that output stores an indication commensurate with the magnitude of each phase difference, the register means operating on a time-sharing basis and registering a particular indication only during reception of the relevant received signal. The description is an omega system receiver in which there are transmitted sequentially from stations A, B, C, D, Fig. 3, carriers on 10-2 kHz-hatched rectangles-and 13À6 kHz (for lane identification) timed as shown. General operation, Fig. 4.-A synchronizer 4-12 generates internal reference signals, is controlled by unit 4-13 for synchronizing reference signals with received signals, and produces "on-time" gates, Fig. 9 (not shown), having durations corresponding to those of the received signals and visually compared therewith. A single phase tracker 4-21 is multiplexed to all the received signals. If a detector 4-14 shows that a signal is present it is employed, after pulse width measurement 4-15, to permit fine synchronization of an internal "clock" in conjunction with early and late gates generated within synchronizer 4-12. The description pertains to the 10À2 kHz signals; automatic phase tracking is performed on the 13À6 kHz signals in an analogous manner. Synchronizing.-A crystal oscillator output is divided down to 10À2 kHz and converted to binary-coded-decimal (B.C.D.) form, and further division and conversion to B.C.D. form is employed, Fig. 5 (not shown). Synchronization with received signals is effected by modification of a division ratio. Display and control.-Juxtaposed rows of lights are respectively energized by the "ontime" gates and under the control of the received signals; the division ratio is manually adjusted until the rows are in synchronism and this, "coarse", synchronization may be sufficient. "Fine" synchronization is indicated by a further visual system. The synchronization has no direct effect on the phase measurement but enables maximum available time to be devoted to it. Phase measurement.-A digital phase tracking arrangement is provided, time-multiplexed for each transmitting station's received signals, and phase numbers for each 10À2 kHz received signal are compared to give the corresponding lines of position, Figs. 7 to 14 (none shown). A visual digital display of lane and lane fraction is afforded, and may be written on a chart recorder, Fig. 1 (not shown).
