IPC: H01R9/26
Filed: 1960-07-19
Abstract: 961,035. Terminal blocks. G. GLASEL. July 19, 1960, No. 25098/60. Heading H2E. A rail-mounting electrical connector consists of a narrow slab-like unitary body 2 of insulating material containing inlet and outlet terminals 4, 5 connected by a fuse 10 mounted inside the body and protected from accidental contact through the narrow edges of the body. In use, several of the connectors are clipped side by side on to the rail 1 and held by their retaining pins 3. Apertures in the main faces (sides) of a connector are thus shielded by adjacent connectors, those in the end connectors of the row being closed by auxiliary end plates. The fuse 10 is held against connecting strip 7 by a cap 9 which screws into the other connecting strip 6 and which has an inspection window 12 in it and may be colour coded to show the fuserating. Circuit information may be displayed on the bevelled edges of the connector body. In other embodiments, Figs. 3 and 4 (not shown), strip or blade fuses are used and are held within the connector body by spring clips. All the embodiments particularly described have clamping bushes for the inlet and outlet terminals but the Specification states that soldering lugs or sockets or squeezing or crimping lugs may be used.

Abstract: 615,962. Chains. GREGORY, A. H. Aug. 23, 1946, No. 25297. [Class 24] [Also in Group XVIII] The level of liquid in a tank A is indicated by a float D which is suspended from one end of a chain E which extends over a rotatable sprocket F coupled to a drum graduated in accordance with the capacity of the tank. The free end of the chain, which acts as a counterweight, depends into an open-topped tubular casing J. The chain is of such length that, when the tank is empty the free end of the chain is just clear of the bottom of the casing J, and the links thereof, preferably of diamond or rhomboidal form, are so dimensioned that, when they rest one upon another at the bottom of the casing, the vertical distance between their midpoints is one-half of that which exists between these points when the chain is in its extended position. The pivot pins K of the links may be provided with rollers L for engagement with the wall of the casing J during folding and unfolding of the chain end.

Patent GB-413522-A (GB)
Title: Manufacture of barbituric acids
Filed: 1933-09-18
Abstract: In the preparation of barbituric acids by condensation of malonic acid esters with urea in the presence of alkali alcoholates, the esters and alcoholates employed are those derived from alcohols containing more than three carbon atoms.  Provided, however, that an alcohol containing more than three carbon atoms is present in the free state, the ester or the alcoholate may be derived from an alcohol containing a smaller number of carbon atoms, particularly ethyl alcohol, for an exchange of alcohol radicles is then effected. According to the examples, (1) barbituric acid is obtained by heating malonic acid dibutyl ester with urea in the presence of sodium butylate, or by heating malonic acid diethyl ester with urea in the presence of amyl alcohol containing sodium amylate; (2) diethylbarbituric acid is prepared by interaction of diethylmalonic acid dibutyl ester in the presence of sodium butylate. Diethylmalonic acid dibutyl ester is obtained by treatment of malonic acid dibutyl ester in two stages with sodium and ethyl bromide.
