Abstract: 149,225. Ihlenfeldt, R., and Scheib, G. Dec. 18, 1918, [Convention date]. Addition to 149,222. Corpses &c., treatment of.-In the process for preserving meat, carcases, corpses, &c. by injecting preservative liquids or gases, described in the parent Specification, in which the material treated is subjected to external fluid pressure about equal to that at which the preservative is injected, thus allowing higher pressures to be used than has been customary in such processes, the preservative is injected at any desired point instead of being passed through the circulatory system. Fig. 2 shows in plan an apparatus for carrying out the process. Liquid is drawn from a reservoir a by a pump b and forced through an air reservoir c to two pipes h, i communicating respectively with nozzles m for injecting the liquid into the material and a closed vessel d for containing the material. A pressure-regulating valve n keeps the pressure in the pipe i about 10 per cent below that in the pine h. Safety-valves o, p in the pipes h, i return excess liquid through pipes s, t to the reservoir a. In a modification, separate pumps are used for supplying liquid to the injection nozzles and the chamber d, so that the variations of pressure due to the strokes of the pumps can be made to differ in phase as desired. Suitable gases are stated to be carbon dioxide and nitrogen; suitable liquids for treating meat for food, hydrochloric acid and hydrogen peroxide; and suitable liquids for other purposes solutions of arsenic, boric acid, glycerine and formalin.

Abstract: 670,618. Voltage measurement. ALLING- HAM, R. A., and JEFFREE, A. F. Aug. 11, 1948, No. 21153/48. Class 37. [Also in Group XL (c)] A measuring instrument comprises a circuit (see Group XL (c)) including a pair of valves V2, V3 (Fig. 3), having a common impedance Z2 connecting the cathodes to earth, an equal impedance Z1 connected between the grid of one valve and the cathodes and a connection between the grid of the other valve and earth, the input to be measured being applied across the two impedances in series to produce currents in the two valves 180 degrees out of phase with each other. In addition since the impedances are equal the anode currents due to the input are equal in amplitude and produce equal and opposite voltages across the cathode resistor. The input may be obtained from a cathode follower valve V1 or by direct connection to the anode of a pre-amplifier valve. Demodulation may be effected by biasing both valves to cut-off and obtaining the output from a common anode load (Fig. 9), in which case a meter Z16 may be connected to the anode load and the D.C. component of the output may be backed off by a potentiometer Z13, Z14, Z15.

Title: Improvements in or relating to the production of sand cores
IPC: B22C1/24
Filed: 1939-07-21
Abstract: 533,851. Sand cores. TENNANT, W. J. (Armour & Co.). July 21, 1939, No. 21222. [Class 91] [Also in Group XXII] Sand cores are made by mixing sand with a core oil composed of a marine oil fatty acid composition containing at least 40 per cent of C 22  fatty acid radicals and a substantially smaller amount of fatty acids of lower molecular weight than C 22  than that contained in a hydrolysed marine oil, forming the sand and oil into the desired shape and baking the mixture. The core oil which is used to make the sand cores of the present invention is derived from marine oils by first partially splitting the oils by hydrolysis and then fractionally distilling the product so obtained. The low molecular weight fatty acids are removed, and the undistilled material comprising the bulk of the C 22  acids together with the unsplit oil is used as the core oil for the present invention. The amount of unsplit oil which is allowed to be present depends on the final characteristics which are desired in the core oil, but if the total quantity of C 22  acids is less than 40 per cent an amount of such acids is added to make the total up to this amount. It is preferred when such acids are added, that the addition should be of esterified form. It is also preferred that the free fatty acid content should not be above 70 per cent., and when this is the case, a portion of the free fatty acids is re-esterified to convert them into the corresponding tri-glyceride. Various modifying agents may be added to the core oil before mixing with the sand, such as volatile hydrocarbons and synthetic resins. Antioxidants such as diphenylamine and driers may also be added to the core oil. A suitable core oil for use in the process of the invention is produced by the process of the example in Specification 533,852.

Abstract: 154,981. Hussander, A. F. Sept. 2, 1919. Motor power plant.-Comprises transmission systems such as for motor vehicles, boats, and aeroplanes, in which two or more prime movers in pairs connected by differential gearing, drive a common propeller shaft. When four engines are used, as shown, each of the engines 72, 73 drives a sun-wheel of a differential 31a, the planet carrier of which drives a shaft 87 through gearing 85. Similarly the engines 74, 75 drive a shaft 88 through another differential gear 31b, while the two shafts 87, 88 drive the propeller shaft 96 through a third differential gear 36, a friction clutch and flywheel 45, and change speed gearing 42. Each sun-wheel shaft of the various differential gears is prevented from running backwards by the friction ratchet device shown in Fig. 4, so that if any engine stops the drive from the rest is still transmitted through the differential gears. The sun-wheel carries pivoted blocks 63 pressed outwards by springs 67 so that they tend to contact with a fixed rim 55. The normal direction of rotation is such that the blocks slip over the rim, but when the rotation is reversed they bind the rim and stop the shaft. One engine of a pair may be started by speeding up the other to store energy in the flywheel 45 and then slowing the other down when the flywheel will cause the stationary engine shaft to rotate. In a modification, shown in Fig. 8, the differential gear can be locked by a friction clutch 105, to enable one engine to start the other.
