Title: Improvements in and relating to weighing apparatus
IPC: G01G1/26
Filed: 1921-04-02
Abstract: 161,178. Salters, J. B. M. April 3, 1920, [Convention date]. Computing-apparatus; loose-weight apparatus. -Relates to computing weighing-scales of the kind wherein the weight of the goods is automatically indicated on a computing dial and in which the capacity of the machine may be increased by the addition of weights to the weights pan. The invention consists in moving the weights and their supports into the weighing position in any desired number without relative movement between the weights and their supports so that the requisite weights may be picked up by the machine. The weights 10 are carried on four sectors 8<a>, 8<b>, 8<c>, 8<d> separately pivoted upon a rotary spindle 5 which carries a cap 14 bearing two spring catches 15<a>, 15<b>. The spring catches are pressed into engagement with the sectors by a cam ring 17. The spindle 5 is rotated by means of a handle 20 and a pinion 18, but before rotation is permitted, it is necessary to depress the handle out of the slot shown in Fig. 3, this depression causing an arm 33 to depress the weight-pan end of the usual weighbeam 21. The rotation of the handle then causes. the catch 15<a> to move the sector 8<a> into a position above the weight pan 28<a> the catch then releasing the sector. If the handle is then allowed to rise the first weight will be picked up by the pan 28<a>. If the rotation of the handle is continued the second catch 15<b> will move the sector 8b over the pan 28b and a second weight may be picked up and so on for the remaining weights. The weights picked up are indicated on number plates operated from the spindle 5 through a bell-crank lever 30.

Title: Improvements in or relating to diol perfluoro esters and diols therefrom
Inventor: FENSKE MERRELL ROBERT
IPC: C07C69/28
Filed: 1955-04-05
Abstract: The invention comprises esters having the general formula: <FORM:0789388/IV (b)/1> wherein R and R1 represent hydrogen or alkyl radicals having from 1 to 3 carbon atoms and n is an integer from 1 to 3, except that R and R1 do not both represent the methyl radical when n = 3, and a method for the preparation of these and other glycol di-esters of aliphatic perfluoro carboxylic acids comprising reacting a saturated epoxide with an anhydride of an aliphatic per-fluoro carboxylic acid at a temperature in the range 25 DEG  to 200 DEG  C. at which the epoxide ring opens.  The reaction is preferably effected in the presence of an esterification catalyst such as zinc chloride, aluminium chloride, sulphuric acid, acetic acid or, desirably, a per-fluoro carboxylic acid corresponding to the acid anhydride reactant.  Normally, at least one mol. of anhydride per mol. of epoxide is used.  Inert solvents may be present and elevated pressure may be used.  The epoxides preferably have a tetra- or pentamethylene ring and include those having the formula: <FORM:0789388/IV (b)/2> wherein n is 2 or 3 and wherein one or more of the hydrogen atoms may be replaced by C1-15 alkyl groups, chlorine, bromine or carboxylic acid or carbalkoxy radicals and numerous examples are given.  There may also be used ethylene oxide, 1 : 2-epoxy butane, 2 : 3-epoxy butane, trimethylene oxide, 2-ethyl-1 : 3-epoxy propane, 2 : 4-epoxy octane and 2 : 4-epoxy pentane. The perfluoro acid anhydrides are preferably those from monobasic acids, e.g. perfluoro acetic, propionic and butyric acids; anhydrides of dibasic acids, e.g. tetrafluoro succinic acid anhydride, are said to tend to yield polymeric compounds.  The glycol diesters may be treated to yield the corresponding glycols by saponification or preferably by alcoholysis with a C1-3 alkanol, if desired in the presence of a catalyst which may be an acid but is preferably an alkali metal alcoholate, a quaternary ammonium base or a basic ionexchange resin; in some cases, simple hydrolysis may be used.  In examples: (1) trifluoro acetic anhydride, obtained by refluxing trifluoro acetic acid with P2O5, is heated with 2 : 5-dimethyl tetrahydrofuran and trifluoracetic acid as catalyst in a glass pressure flask at 95 DEG  C. and the products are worked up to isolate the resulting hexane-2 : 5-diol di-trifluoro acetate and a small amount of hexene-5-ol trifluoroacetate; the di-ester is alcoholysed with methanol to give the free diol; (2) the catalyst used in (1) is replaced by zinc chloride; (3) the epoxide and anhydride of (1) are refluxed at atmospheric pressure in the presence of zinc chloride catalyst and then further heated in a closed vessel at 95 DEG  C.; the resulting di-ester is then alcoholysed with methanol in aqueous hydrochloric acid; (4) the method of (2) is repeated and the di-ester containing product, without isolation, is alcoholysed as in (3) yielding the free diol and some hexenol.

Title: Rna ribozyme restriction endoribonucleases and methods
Inventor: CECH THOMAS R
IPC: C12N15/10
Filed: 1995-12-14
Abstract: RNA enzymes or ribozymes can act as endoribonucleases, catalyzing the cleavage of RNA molecules with a sequence specificity of cleavage greater than that of known ribonucleases and approaching that of the DNA restriction endonucleases, thus serving as RNA sequence specific endoribonucleases. An example is a shortened form of the self-splicing ribosomal RNA intervening sequence of Tetrahymena (L-19 IVS RNA). Site-specific mutagenesis of the enzyme active site of the L-19 IVS RNA alters the substrate sequence specificity in a predictable manner, allowing a set of sequence-specific endoribonucleases to be synthesized. Varying conditions allow the ribozyme to act as a polymerase (nucleotidyltransferase), a dephosphorylase (acid phosphatase or phosphotransferase) or a sequence-specific endoribonuclease.
