Abstract: C-Chloro derivatives of amino acids, the Cl being attached to a carbon not containing an amino group, are obtained by intimately contacting an amino acid containing a chain of at least 3 carbon atoms, or an N-(C1- 5 alkyl), N,N-di-(C1- 5 alkyl), N-acyl, N,N-diacyl, N-(C1- 5 alkyl)-N-acyl, ester, acid halide, amide or cyclic anhydride of such an amino acid, with free chlorine atoms under the influence of a free radical initiating means and in a strongly acidic reaction medium containing at least one mole of acid per mole of amino acid.  The invention also comprises the compounds g -chloro-L-glutamine, g -chloro-L-glutamic acid hydrochloride, b -chloro-L-glutamic acid, g -chloro-L-lysine and g -chloro-DL-ornithine.  The chlorination may be effected with chlorine gas or an N-chloro-imide, and the free radical initiating means may be chemical, e.g. of the azo type, or may be ultra-violet or fluorescent light or X-rays.  The products may be hydrolysed to produce hydroxy amino acids.  The N,N1-dibenzoyl derivatives of the lactones of g -hydroxy-L-lysine and g -hydroxyornithine are obtained by reacting the hydroxy amino acid with benzoyl chloride, and heating the isolated product in solution in toluene.  The lactones of a -amino-g -hydroxybutyric acid and g -hydroxyvaline are obtained by refluxing the hydroxy amino acids with aqueous HBr.

Abstract: Acetone-soluble, fusible, ternary interpolymers are made by heating in the presence of peroxide catalysts a mixture of (a) styrene or p-chloro- or p-methyl-styrene; (b) diallyl or dimethallyl fumarate and (c) allyl or methallyl alcohol and halting the reaction by cooling, if desired adding an inhibitor such as hydroquinone, before gelation occurs.  The proportion of the alcohol is at least 10 per cent of the fumarate.  Excess of the alcohol may be used as a solvent.  Catalysts specified are acetyl, benzoyl, acetyl-benzoyl and succinyl peroxides and tert-butyl hydrogen peroxide.  Modifiers such as carbon tetrachloride may be present.  The product may be purified by solution in acetone and precipitation with gasoline.  The interpolymers may be modified by reaction with alkyl, allyl and acyl halides and dihalides, organic acids and anhydrides, e.g. polycarboxylic acids and chloracetic anhydride, aldehydes or organic isocyanates, isothiocyanates and diisocyanates.  Dyes, pigments, e.g. titanium dioxide, fillers, plasticisers and solvents, e.g. acetone, cyclohexanone, carbitol acetate and xylene may be incorporated into the product, which may be further heated, if desired with addition of catalyst, to the insoluble, infusible stage.  The product may also be dissolved in methyl or allyl acrylates, vinyl acetate or diallyl fumarate and further polymerized.

[Also in Division F1] A piston burette comprises a reservoir with a small discharge opening adapted to be filled with the liquid to be dispensed, a movably mounted rod having means projecting axially into the reservoir to displace liquid through said discharge opening, a micrometer assembly including a micrometer screw for moving said rod a predetermined axial distance for each revolution of the micrometer screw, a wire-like element having both ends attached to the rod and being at least partially wound on the rod, measurement indicator means including a rotatable control pulley engaging an intermediate portion of said wire-like element for indicating the linear movement thereof, and spring takeup means for continuously applying tension to the wire to maintain the same in actuating contact with said control pulley. The burette is a modification of that disclosed in Specification 811,838, and operates in a similar manner. As shown in Fig. 6, tube 16 contains rod 22 connected at one end to micrometer 12 and protruding at the other end into reservoir 26 having delivery nozzle 67. The wire or wirelike element 18 is secured at both ends to the rod, and an intermediate portion 18-1 passes from the rod portion 62 over pulley 60 which controls a dial indicator 21. Portion 18-2 passes from pulley 60 to pulley 61, and portion 18-3 passes back to the rod. Pulley 61 is rotatably mounted on shaft 64 and is spring-pressed by spring 66. The wire may be of steel, or for example of nylon or silk. The end of tube 16 is sealed as shown in Fig. 7 to prevent liquid penetrating therein. A first sealing means is formed by conical member 80 and the conical opening 83 of sleeve 70, the slope of the former being less than the slope of the latter so that a live contact is made therebetween. Sleeve 70 has in its inner surface annular recesses 71 and 72 containing respectively 0-rings 73 and 74 held in place by washer 76 and forming a second sealing means.

Title: Coin testing apparatus
Inventor: DORT KLAAS PIETER VAN
IPC: G07D5/02
Filed: 1985-10-03
Abstract: A coin testing apparatus (10) comprises a coin passageway, a coin track (13) along which coins pass on their edges through the coin passageway and an inductor (16) adjacent the coin passageway. The inductor is connected in an oscillating circuit (40) so that the inductor (16) produces an oscillating magnetic field in the coin passageway. The frequency of the oscillating circuit is measured using a counter (41). A number representative of the idle frequency is stored in register (44). When a coin passes the inductor (16), the apparatus (10) detects whether the resulting frequency shift corresponds to the shift for an acceptable coin by comparing the difference between the number stored in register (44) and the number stored in counter (41) with a number previously stored in memory (48). The inductor (16) is oblong and has its major axis perpendicular to the track so that the arrangement is sensitive to variations in diameter over a large range of diameters.
