Abstract: 669,433. Electric measuring systems. MORLE, C. W. (Graham-Mintel Instrument Co.). Oct. 11, 1949. No. 26075/49. Class 40 (i). In a gauging circuit wherein an alternating signal voltage is generated, whose magnitude and phase sense vary in accordance with the deviation of a gauged object from a standard, the signal voltage, after suitable amplification, is fed in anti-phase to the grids of two balanced triodes or their equivalent, the anodes of the two. triodes. being fed in like phase with a reference voltage in phase with the signal voltage on one of the grids of the two triodes, and a centre zero D.C. motor connected across the anodes indicates the signal voltage amplitude and phase sense. 'The core 18 of e.g. an E type transformer 10, is moved by the element being gauged to produce the signal voltage in the normally balanced opposed secondaries 14a, 15a. This signal is fed through transformer 20, and a tuned grid circuit to remove harmonics and other spurious signals, to the grids of a double triode 25 in antiphase. The .tubes 25, 30 give two stages of push-pull amplification with negative feed back for stability, the amplified version of the signal being fed in anti-phase'to the grids of a double triode 40 the anodes of which are fed in like phase from the same power transformer 50 that feeds the E type transformer through winding 52, so that the anode voltage is in phase with the voltage on one grid or the other. A centre zero D.C. meter M connected across the anodes then indicates the magnitude and phase sense of the signal and hence the magnitude and .sense of the deviation of 'the gauged element from the standard. The anodes of tube 40 are fed through a potentiometer P to permit zero adjustment of the meter and the amplification in stage 25 may be adjusted by a variable resistor shunted across the cathodes thereof or in other ways, Figs. 3, 4 (not shown). Specification.587,581, [Group XXXVI], is referred to.

Filed: 1928-09-14
Abstract: 297,122. Pintsch Akt.-Ges., J. Sept. 16, 1927, [Convention date]. Spray evaporators; hydrocarbons, distilling.- Liquids, e.g. oils, are distilled by direct contact with hot gases and the gaseous products remaining after separation of the condensible constituents are burnt with air in a regenerator which is used for initially heating the gases and is separate from the distillation chamber. A heating chamber 1 is surrounded by a regenerator divided into two chambers 2, 3. The gases are initially passed into the chamber 2 through a port 9 and when heated by contact with the hot brickwork pass into contact with the liquid admitted in drops through a port 5. The gases and the vapours produced are separated from undistilled liquid in a chamber 6 and pass through a condenser 15 where the vapours are condensed the gases being then pumped through a port 10 to the chamber 3 they are mixed with air admitted through a port 11 and burnt. The chamber 3 is thus heated and serves to heat fresh gases, the process being repeated continuously. Reference is made to Specification 295,717 [Class 55 (i), Coking &c.].

Title: Improvements in or relating to hoisting or lifting gear
IPC: B66D1/20
Filed: 1919-10-29
Abstract: 158,324. Reading, H. C. Oct. 29, 1919. Geared pulley-hoists; brakes; driving-gear; control-transmitting gear; stopping automatically at end of run.-In winding-apparatus driven by a disengageable friction gear, the friction elements are forced together with a pressure proportional to the load and the pressure of the brake is also proportional to the load. Means are fitted also for preventing overwinding. As shown, a coned friction member b is formed integrally with the hoisting drum shaft a<1>. A friction cone e slidably mounted on a power shaft f is forced into engagement with the memhers b, c by the upward movement of a wedge g over the fixed inclined surface h. The wedge g rests on, or is coupled to, the arm j of a three-armed lever i, the other arms of which are connected to the brake p and the hoisting-rope l. An actuating-rod depends from one extremity of an operating-arm fixed to the lever i, and the other extremity is counterweighted. With the parts in the position shown in Fig. 2, the wedge g forces the cone e into engagement with the surfaces b, c, and the pressure between the engaging surfaces is proportional to the load carried by the hook n. If the arm is now turned to move the lever in a clockwise direction, the wedge g is withdrawn, and the brake block r is applied to the conical surfaces of the members b, c with a pressure proportional to the load. Overwinding is prevented by the contact of a stop t on the rope l with the sheave m. When this occurs, the rope above the stop becomes slack and the lever i moves in the clockwise direction under the weight of the actuating- rod.

[Also in Division C6] A process for producing yeast cells or spores having improved resistance to dehydration and improved storage properties comprises dispersing mature vegetative cells or growth in an aqueous solution containing 0.1 to 0.5% wt./vol. acetic acid radicle (provided as acetic acid or potassium acetate) at a pH of 5.5 to 6.5, aerating the suspension and as the acetic acid is metabolized and the pH rises, continually feeding acetic acid to adjust the pH to approximately 4.8 to 6, for at least 10 hours. The yeast cells are preferably maintained in the acetic acid suspension until at least one-half of the cells have formed spores, after which the pH is adjusted to approximately 4.0 to 5.5 with sulphuric, hydrochloric or citric acid and sporulation is allowed to continue for a further 6 to 12 hours. The spores and spore-containing yeast cells are then separated from the medium, dehydrated to a low moisture content and stored at room temperature or under refrigeration in a dry atmosphere, e.g. in the presence of silica gel. The yeast cells may, however, be dehydrated before (or without) spore formation. High yeast cell densities of 100 to 250 million or more cells per ml. are used.
