Title: Improvements in electrical testing equipment
IPC: G01R19/155
Filed: 1940-03-29
Abstract: 536,360. Detecting faults. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and SAVILLE, W. March, 29, 1940, No. 5661. [Class 37] In a portable testing set for testing the intrinsically safe character of electrical equipment installed in fiery mines the voltage produced by interrupting the current flow from a given source through the equipment under test is operative on a voltage responsive device. An "intrinsically safe" apparatus such as a bell or relay is protected by a safety shunt across its terminals, and the purpose of the test is to determine whether the safety shunt connections are intact. A standard "safe" coil S, of high inductance and protected by a safety shunt, and a standard "unsafe" coil US, of low inductance and unshunted, are connected through switches A, B1, B2, C1, C2 to a battery BT and a neon lamp N connected across the tapping on a potentiometer P. The keys A, B1, B2 are operated to connect the coil US to the battery BT, and when saturation has taken place the key A is released so that the inductive potential generated by the coil US is applied across the potentiometer P. The potentiometer is adjusted so that the neon lamp just strikes. This adjustment is checked by manipulating the keys A, C1, C2, when the neon lamp should not glow. The equipment to be tested is then connected to terminals T1, T2 and the key A is momentarily operated, when a glow should not be produced. The calibrating coils US, S may be separate from the testing box, and the "unsafe" coil US may be energized from the low voltage test box battery BT while the "safe" coil S is energized from a higher potential such as 30 volts. Instead of the two coils US, S, a single coil normally unsafe may be provided with a safety shunt which can be connected across its terminals by a key. In order to test the neon tube an additional key may be provided for altering the potentiometer tapping so as to produce a flash on the neon tube from the equipment under test.

Title: Manufacture of thermally-insulating refractory articles
IPC: C04B35/66
Filed: 1973-02-06
Abstract: 1468796 Moulding compositions D A J PATTERSON and T A WILLIAMS 5 Feb 1974 5813/73 Heading C3N A moulding composition for use in the manufacture of thermally-insulating refractory articles has the consistency of a "plastic solid" and contains water and/or other liquid, 1-20% by weight of paper fibres and/or cardboard fibres and 60-95% by weight particulate refractory material, the percentages being based on the dry solids content of the composition. A "plastics solid" is defined as having a consistency such that when a shovelful of the composition is deposited on a flat surface it merely slumps without showing any further tendency to flow out over the surface after the initial slump. The moulding composition has a consistency similar to that of brick-laying mortar and generally has an apparent viscosity of at least 200,000 centipoises (254). The particulate refractory material may be crushed fire-brick with a particle size not exceeding 10 mesh (B.S.S.). The composition may also include a binder and/or sintering agent, e.g. ball clay, a filler having a substantially lower density than the refractory filler, or an inorganic fibrous material. The moulding composition may be produced by three different methods. The first method comprises mixing paper and/or cardboard together with liquid in a mixture, subjecting the mixture to mechanical agitation until a fibrous pulp is formed, and then mixing in the particulate refractory material. In the second method the paper and/or cardboard, particulate refractory material and liquid are mixed simultaneously. The third method comprises introducing paper and/or cardboard and liquid into pulping equipment, mixing the mixture in the pulping equipment into a thick liquid pulp, and then adding the particulate refractory material. In the examples plastic solids are formed from water, newspaper, crushed fibrebrick and phenol formaldehyde novolak resin as binder (1); paper, crushed fire-brick, calcined alumina, ball clay, dextrine and water (2); and cardboard, water, alumino-silicate refractory powder, calcined alumina, alumino-silicate fibres and phenol formaldehyde novolak resin.

Title: Extraction of somatotropin-containing fraction from human placenta
Inventor: BUTTI ADRIANO
IPC: A61K38/22
Filed: 1965-02-11
Abstract: A process for the preparation of a somatotropin-containing extract from human placenta comprises extracting human placenta with an aqueous alkaline solution of pH 9.5-10.5, adjusting the pH of the extract 4.0-4.2, and subjecting the extract to differential reprecipitation with sodium chloride or ammonium sulphate to give a somatotropin-rich precipitate which is dissolved in water and freeze-dried.  In an example, human placenta is ground at -15 DEG C, homogenised with acetone, and the homogenisate is filtered to give an acetone-dry powder which is extracted with lime water.  The lime water extract is half saturated with ammonium sulphate, the precipitate obtained being dissolved in water and dialysed.  The pH of the dialysate is adjusted to 4-4.2 and the solution is 1/5th saturated with ammonium sulphate to yield an initial precipitate which is removed followed by 2/5th saturation with ammonium sulphate to yield a precipitate which is recovered and dissolved in water, the solution being dialysed and lyophilised to give a fraction rich in somatotropin.
