Title: Improvements in method and means for controlling the supply of lubricant, or lubricant and abrasive, in polishing glass and the like substances
IPC: B24B57/00
Filed: 1922-03-16
Abstract: 198,472. Taylor, W., and Kapella, Ltd. March 16, 1922. Addition to 126,489. Supplying abrading-materials and fluids.-The apparatus described in the parent Specification is modified so that it operates under conditions which sometimes arise with polishers made of felt &c., when the friction between the polisher and work increases as the supply of liquid or liquid and abrasive is increased. The air-pipe connectin the dynamometer to the cylinder, which operates the needle-valve controlling the supply cf lubricant &c., is transposed to the opposite end of this cylinder and thus produces the reverse effect upon the piston. The apparatus can be fur. ther modified, to give a warning to an attendant, for example by connecting the air-pipe to a pneumatic indicator instead of to the cylinder. Instead of a pneumatic indicator, an electric bell or lamp may be used, the circuit thereof containing a contact or the dynamometer. Upon the receipt of the signal the operator may control the supply of lubricant &c. by means of a valve inserted in a pipe conveying compressed air to the cylinder, which operates the aforesaid needle-valve. Alter natively, or in addition, a pencil may be attached to the dynamometer, to trace a graph of the variations of friction, and so to give an indication of the necessity or otherwise, for fresh lubricant. The apparatus can be modified still further by utilizing the variations of load upon the electric motor driving the polishing-machine to operate a switch controlling an auxiliary circuit. Such auxiliary circuit is used either to control the supply of liquid &c. or to operate a warning signal.

Abstract: 543,736. Kaolin product; purifying air and oils; dentifrice. WELLS, A. B., WELLS, C. M., WELLS, J. C., COZZENS. C. O., SPENCER, jun., C. E., MOSHER, I., SHELDEN, C. N., WELLS, jun., C. M., WELLS, G. B., WELLS, J. M., WELLS, A. T., and WILLIAMS, E. E., (constituting AMERICAN OPTICAL CO.), April 30, 1940, No. 7767. Convention date, May 1, 1939. [Classes 1 (iii) and 91] [Also in Groups VI and XXVIII] A material, primarily intended as a rouge substitute is obtained by subjecting kaolinic clay to a heat treatment for a sufficient time' to permit the individual particles of clay to reach a temperature of 1000-2100'F. without causing an appreciable portion of the clay to sinter during the removal of the water of hydration and also during the subsequent heat treatment. A fine grained non-toxic non-staining material is obtained after grinding, which is suitable for polishing glass but also as a pumice substitute in toothpaste, as a dust filter, a solid adsorbent or catalyst. It may also be used in purifying oils. In order to find the best temperature for treating the kaolin, a test is made in which the course of calcination is followed by means of thermo-couples, one being freely exposed in the furnace and the other embedded in the kaolin. In the case of the kaolin examined, the best temperature, confirmed by actual polishing of glass, is a point somewhat lower than the temperature at which the re-action becomes exothermic.

Patent GB-1047913-A (GB)
Title: Process for manufacturing a urea-formaldehyde fertilizer
IPC: C05C9/02
Filed: 1965-02-24
Abstract: A urea formaldehyde fertilizer is prepared by subjecting one molar proportion of urea to partial condensation with from 3-6 molar proportions of HCHO under alkaline conditions whilst the reacting mixture is simultaneously evaporated to give a concentrate containing more than 50% by weight of solids, mixing urea with the concentrate to provide the urea to HCHO molar ratio desired in the fertilizer, further condensing the mixture by the addition of acid and subsequently terminating the condensation rapidly by the addition of alkali, e.g. NaOH.  The product may be granulated and thereafter dried.  The initial condensation may be performed with 4-5 mols of HCHO per mol of urea.  The further condensation of the urea formaldehyde solution after acidification may be effected in an evaporator provided with a feed screw into which evaporator the alkali is fed to neutralize and interrupt the reaction after the desired degree of condensation has been obtained.  Alternatively the further condensation may be effected on a conveyer, from which the mixture is passed to a kneader together with the alkali. The final product may be granulated.

Title: Improvements in stamps or hammers
IPC: B21J7/24
Filed: 1955-03-19
Abstract: 798,748. Power hammers. MASSEY, Ltd., B. & S., PICKWORTH, P. C. N., and BAINBRIDGE, F. March 19, 1956 [March 19, 1955], No. 8081/55. Class 83 (4). A drop stamp or hammer has its tup 10a raised by hydraulic fluid supplied continuously beneath a piston 12a and this fluid is also admitted above the piston to effect the downstroke. A pump 15a, preferably of constant delivery, driven by an electric motor draws liquid from a tank 14a and delivers it through pipe 18a to the space below piston 12a which space communicates with an air cushion accumulator 16a. For raising the tup an exhaust valve 22a is opened whereby the liquid above the piston is returned to the tank through pipe 23a. Near the end of the upstroke the exhaust valve is closed and an inlet valve 21a is opened to admit pressure liquid from pipe 20a and thereby cushion the end of the stroke. Inlet valve 21a may then be closed to retain the tup at its top position or it may remain open whereby the differential pressure on the piston assists gravity in performing a further blow or blows. The inlet valve is closed and exhaust valve opened at the end of the downstroke or earlier if lighter blows are required. Variation of the blows may alternatively be effected by shortening the stroke- or by throttling the liquid supply through the inlet valve 21a. A by-pass or unloading device for the pump is operated in response to the accumulator pressure. The inlet and exhaust valves 21a, 22a may be operated manually or automatically by the tup movement or changes in fluid pressure. For performing slow downstrokes during setting, pressure liquid is supplied above the piston through a pipe 28a controlled by a small hand valve 29a. A second hand valve 30a permits exhaust for slow raising of the tup. In another embodiment the extension rod 26 above the piston is omitted.

Abstract: 1427301 Testing pulse code modulation transmission equipment COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 27 Feb 1974 [27 Feb 1973] 8837/74 Heading H3H A pulse code modulation encoder 2 is tested by applying a low frequency alternating voltage 4 to one of the channels V 1 -V 30  of amplitude corresponding to the maximum coding level (1111111) and checking that the number of times this maximum code occurs in the output of the encoder during a test interval of 1 second exceeds a predetermined minimum (e.g. 99), reducing the amplitude of the alternating voltage by 1 dB and checking that no maximum code occurs in the output during a further test interval of 1 second. Occurence of the maximum code is detected by AND gate 8 connected to a shift register 7 into which the output of the coder 2 is fed. Positive or negative maxima may be detected, selected by S + and S - signals, AND gates 10, 11 and a sign bit from register 7. AND gate 9 is enabled at the appropriate clock instants when complete output codes for the tested channel are in the register 7, under the control of clock 3, counters 31, 32 and channel selector 33. The test interval is determined by a monoflop 14 and AND gate 13, the detected maxima being counted in a two decade counter 16. When the counter fills (i.e. at 99) AND gate 17 inhibits AND gate 13 to retain the count of 99 for display at 19.
