Abstract: 710,609. Impedance measurements. COMPAGNIE GENERALE D'ELECTRICITE. June 30, 1952, No. 16398/52. Class 37. Apparatus for measuring the propagation constant of a transmission line 3 comprises a generator 1 calibrated at adjustable frequency connected between the two conductors of the line at one end, a voltage indicating device 4 connected between the two conductors at the other end, and a calibrated variable capacitive reactance connected between the two ends of each pair forming the line at 6. The indicator 4 is automatically tuned to the frequency of the generator 1 when this is varied. The apparatus 6 comprises two paths AB, A 1 B 1 , each composed of two condensers in parallel. The condensers C I   1 <SP>1</SP>, C 2   1 <SP>1</SP> are ganged so that their capacitances always remain equal, while the condensers C 1 1 <SP>2</SP>, C2  1 <SP>2</SP> are ganged so that their capacitances vary in opposite directions, starting from a common value. The condensers C1  1 2 '  C2  1 2 are adjusted to their common value and the frequency of the generator i and the capacitance of the condensers C1  1 1 ,  C2  1 1 are simultaneously adjusted until the indicator 4 gives a minimum reading. Balance is then perfected by adjustment of the condensers C1  1 2 ,  C 2 1 <SP>2</SP>. The propagation constant of the line can then be determined from the frequency of the generator and the capacitances of the condensers.

Rods, locking.-Relates to means for locking relatively slidable members, of the kind in which single or oppositely acting gripping elements, pivotally carried by one of the members, are formed with apertures through which the other member passes and, when tilted, grip such member to prevent relative movement in one or both directions, and comprises an arrangement in which the gripping element or elements are provided with round hardened steel cross-bars forming wearing surfaces in the apertures, and are formed with elongated channels or grooves providing the engaging means for the pivotal supports. In the form shown in Fig. 1, a box-like frame A slidably mounted on a stationary bar C carries a single gripping element B normally preventing movement in one direction. The round steel wearings bars 2 lining the aperture 8 may be inserted in transversely drilled holes or in recesses provided for them in casting or forging the gripping element. A groove or channel 3 provides the pivotal connection with a fulcrum pin 1. The gripping element may normally be tilted by a spring D, by gravity, or manually. Lugs 4, 5 provide for the attachment of parts to the frame A. Alternatively, the frame A may be provided with flanges for attachment to a fixed part and the bar C may constitute the slidable member. A pair of oppositely tilting gripping elements may be provided to prevent motion in both directions.

Title: Foundry mold material and method
IPC: B22C9/00
Filed: 1960-05-10
Abstract: 943,488. Moulding processes. MORRIS BEAN & CO. May 10, 1960 [May 11, 1959], No. 16490/60. Heading B3F. [Also in Division C1] A foundry moulding process comprises pouring on to a pattern a granular mould material which includes a dry gas-activatable binder and activating said binder by permeating the mould material with an activating gas. The mould mix constituents are mixed in a muller while heating to produce binder-coated grains which are poured on the pattern 15, settled if desired by directional vibration and jolting or both, and placed in a chamber 21 which is evacuated before the activating gas, e.g. CO 2 , HCl, SO 2  and other acid anhydride gases, ammonia gas, is supplied through a top plate 30 and a perforated or permeable diaphragm 33. Temperature rise during gassing may serve as an indication of the correct gassing time and also, by sampling during drying serves to determine the point to stop drying. Shrinking which occurs with a metasilicate binder may be minimised by gassing with CO 2  at a temperature below 68‹ F. or by chilling the sand during gassing to about - 15‹ C. but without freezing the water formed by reaction with the gas. To avoid overdrying during gassing, the gas may be bubbled through water before it reaches the sand. The moulds may be heated preferably in the range 150-250 F. by radiant, infra-red or dielectric heating after gassing. Mould and core materials.-Examples of binders about 3-10% are alkali metal silicates such as sodium meta-, ortho-, and sesquisilicates or mixtures thereof, or other silicates to which hydrated compounds such as barium hydroxide octahydrate, borax or hydrated crystalline silicates which release water when gassed may be added, sodium aluminate, barium hydroxide monohydrate ferric, nickel, and cobalt, chloride, sodium, potassium and calcium phosphate, boric acid, oxalic acid, anhydro formaldehyde aniline in saturated toluene solution. A small amount e.g. “-1% of a carbohydrate such as dextrin or corn flour or a urea material may be added to minimise shrinkage. Blown mica or fibrous material such as 2% asbestos, glass fibre cotton or bast fibre, slag wool or other light weight particles and certain kinds of clay may also be added. For casting magnesium inhibitors such as fluoborates or fluosilicates, sulphur may be added. Specification 749,813 is referred to.
