Title: Improvements in or relating to tipping skips and other bodies for use with cranes or other hoisting and lowering apparatus
IPC: B65D88/56
Filed: 1927-03-25
Abstract: 285,291. Beaton, E. B., and Barnard, D. J. March 25, 1927. Tip-boxes and tip-buckets. - Relates to tip. buckets &c. in which the pivotal connection with the bail moves automatically when the bucket, either upright or inverted, is set down, to a position below -the centre of gravity, so that the bucket tips automatically when again lifted. As shown in Fig. 1, a weighted double hook 27 cooperating with pins 21c, 21d on the bucket is pivoted on the trunnion 5 which is carried on a slide block 23 moving between stops 21<a>, 21b on a guide 21 on the bucket. The arrangement may be duplicated at the other side of the bucket. When the bucket is set down, the member 27 swings clear of the pin 21<c> and the bail is lowered until the lower hook of the member 27 passes beneath the pin 21d. On lifting, the bucket tips about the trunnion 5 and when the inverted bucket is set down the parts move in the same manner so that the bucket is self-righting. In a modification, Fig. 1, hooks 27 engage beneath the end stops 21a, 21b. In these arrangements, the hooked arms act as tension-members between the bail and the bucket. As shown in Fig. 5, arms 27 pivoted on the bucket act substantially vertically as struts between the bucket and the slideblock 23, the arms being weighted to take the position shown and the block passing down between them. In a modification, Fig. 7, the pivoted strut 27 acts against a stop 23c on an arm 23d pivoted on the bucket at 1<a> and moving between stops 21e, 21f. With this arrangement the bucket tips in one direction only.

Title: Improvements in or relating to television and like systems
IPC: H04N5/08
Filed: 1938-05-31
Abstract: 515,427. Television. FAUDELL, C. L. May 31, 1938, No. 16195. [Classes 40 (iii) and 40 (v)] A circuit for the amplitude separation of picture and synchronizing signals comprises an impedance effectively shunted by a unilateral conducting device biassed to be non-conducting during synchronizing pulse periods and so arranged that picture signals are substantially eliminated from the voltage set up across the impedance, which voltage controls a scanning generator. An impedance 4, Fig. 1, in the anode circuit of the valve 2, is shunted by a diode 12. When a picture signal is applied in a positive sense to the grid 1, the diode 12 is conducting, thus shorting impedance 4 so that the anode impedance is effectively impedance 3, the amplified picture signals being taken from terminal 5. When a synchronizing pulse is fed in a negative sense, the diode 12 is non-conducting, the effective anode impedance then being that of impedances 3 and 4 in series. Amplified synchronizing pulses are fed to the valve 7 which is biassed by its grid current to only conduct during synchronizing pulse periods, this having the effect of improving their shape. The frame pulses are taken from across condenser 14 and the line pulses from winding 15 which may be wound on the transformer of the blocking oscillator and is connected to the screen of valve 7. The effects of interference may be eliminated by connecting the anode of an additional diode to the cathode of diode 12 and suitably biassing its cathode, or by the grid current of valve 7 if the amplitude of the pulses applied to this valve are sufficiently great. If synchronizing signals are applied in a positive sense to the grid 1, it is necessary to reverse the connections of the diode 12. In a second embodiment, Fig. 2, a self-establishing D.C. amplifier of the type described in Specification 422,906 is used. Synchronizing signals are applied to the grid of pentode 16 in a positive sense. The anode of the diode 18; which is effectively in shunt with impedance 17, is connected to the anode of pentode 16 so that diode 18 is non-conducting when a synchronizing signal is applied. The voltage drop occurring at terminal 24 is applied to the line and frame deflecting circuits along leads 25, 26, these pulses being separated by circuits 30, 31. On reception of a picture signal diode 18 is conducting and no potential is applied to leads 25, 26. In further embodiments a gas discharge tube may be used as the unilateral conducting device.

Abstract: 515,582. Making emulsions. GOMM, A. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 7, 1938, No. 16892. [Class 1 (i)] [Also in Group IV] Dispersions of ethylene polymers or derivatives thereof, or ethylene interpolymers in aqueous media are made by dissolving the substances in a volatile organic solvent immiscible or sparingly miscible with water, emulsifying the solution in an aqueous medium in the presence of an emulsifying agent and/or in the presence of the components thereof, if desired in the presence of a protective colloid, and then removing the volatile solvent. Preferably the polymer is dissolved in hot or boiling solvent, the emulsifying agent or compounds added to the solution, and during agitation at an elevated temperature there'is added hot water or an aqueous solution containing an amount of the emulsifying agent or compounds thereof, or the initial solution may be. added to the hot water or aqueous solution. The emulsion is then maintained hot, e.g., about 60-80C., agitated and a current of gas, e.g., nitrogen or air is passed through or over the liquid. This gas'is preferably moist, to avoid undue loss of the aqueous phase. If desired, the emulsion may be homogenized or treated in a colloid mill. Violent agitation of the emulsion should be avoided, as tending to cause coagulation. Suitable solvents include benzene, toluene, xylene, petroleum ether, trichloroethylene or other halogenated hydrocarbons. Emulsifying agents include alkali, ammonium or amine salts, e.g., triethanolamine or cyclohexylamine, of aliphatic acids containing over 6 carbon atoms or mixtures obtained from animal fats or oils or from chinawood oil, castor oil, linseed oil or soya bean oil, e.g., stearic, oleic, and hydroxystearic or linseed oil acids. Mixtures of the potassium and triethanolamine salts may be used. Similar salts of sulphuric esters of aliphatic alcohols containing over 6 carbon atoms, e.g., sperm oil alcohols or dodecyl alcohol, or other sulphonated derivatives of aliphatic compounds, e.g., the sodium salt of oleyl-panisidine sulphonic acid may also be used.
