Novel compounds of the formula where R is a mono or dimethylamino group or a mono- or diethylamino group, and the ethanoanthracene is substituted in the 2- or 3-position by a chlorine atom, and salts thereof, are obtained from a compound of the formula which is substituted in the 2- or 3-position by a chlorine atom, and in which X represents a group corresponding to group of formula -CH 2 CH 2 CH 2 R in which at least one of the methylene groups vicinal to the nitrogen atom is replaced by a carbonyl group, by selective reduction of the carbonyl group to a methylene group, for example by means of LiAlH 4  or analogous amide reducing agent. A monomethylamino or monoethylamino group can be converted to dimethylamino or diethylamino by methylation or ethylation by use of a reactive ester or by reductive alkylation. #- [2 - Chloro - 9,10 - dihydro - 9,10 - ethano - (1,2) - anthryl - 9] - propionic acid dimethylamide is obtained by reducing 2-chloro-9-anthraldehyde with NaBH 4  to 2-chloro-9-hydroxymethylanthracene, reacting this with malonic acid diethylester using NaH to yield 1-(2-chloro- 9-anthryl) -ethane-2,2-dicarboxylic acid diethyl ester which is hydrolysed to give 1 -(2-chloro-9- anthryl) - ethane - 2,2 - dicarboxylic acid. This acid is heated to 220‹ C. to form #-(2-chloro-9- anthryl) - propionic acid which is reacted with ethylene to give #-[2-chloro-9,10-dihydro-9,10. ethano - (1,2) - anthryl - 9] - propionic acid. The acid is converted to the acid chloride and reacted with dimethylamine to give the required amide. Similarly #-(3-chloro-9-anthryl) propionic acid is reacted with ethylene to form # - [3 - chloro - 9,10 - dihydro - 9,10 - ethano - (1,2) - anthryl - 9] - propionic acid which is converted to the chloride and reacted with dimethylamine to form the dimethylamide. The monomethylamides of the 2-chloro and 3- chloro-acids are similarly obtained. Pharmaceutical and veterinary compositions comprise a compound of the first general formula above in admixture with a suitable carrier in forms suitable for oral or parenteral administration.

[Also in Division G4] In optical pattern-recognition apparatus, a plurality of series-connected photo-sensitive bodies are connected between electrodes feeding recognition logic. A plurality of photo-sensitive elements on to which a pattern is imaged are connected in series to increase the signal/noise (light current/dark current) ratio. The elements may be individual semi-conductor P-N junctions connected by wires in the sequence P-N, P-N, P-N .... Alternatively, a layer of P- type material may be provided on a rod of N- type material and each sort of material segmented into a series of separate regions by transverse insulating layers, the insulating layers for the P-type material occurring alternately with those of the N-type material, effectively providing P-N and N-P junctions alternately or a two-dimensional plane may replace the rod, with insulating layers running horizontally and vertically or diagonally. The elements may each be a piece of N-type material coated with P-type, the latter being segmented into two or four sections by insulating layers, and separate elements being bonded together by metallic solder or silver paste to form a linear or matrix array respectively. Such a linear array may be produced by cutting a bar of N-type material coated with P-type material. A plurality of series of photo-sensitive elements may be connected in parallel to form a matrix array, and cross-coupling between alternate junctions in adjacent rows may be provided. Connections within a matrix of elements may be diagonal. The elements may themselves be rod-like, the long dimension extending transverse to the direction in which they are connected in series. Two such series of elements may be connected in series, the P-N junctions in one series being oppositely oriented to those in the other so that by choosing the polarity of a bias voltage applied to all the junctions (in series), a selected one of the two series alone may be rendered responsive to light. A plurality of series as above may be arranged to form a matrix, circular or cross-shaped array to allow detection of the following features respectively: convexities (the matrix having electrodes suitably positioned on the edges), closed rings, branched or bent patterns. The pattern may be a character identified by logic means from the outputs of a plurality of series of photosensitive elements on to which the character is imaged. These outputs may also be provided optically using electroluminescent devices. Solar batteries and photo-transistors are also mentioned, as are the materials silicon, cadmium sulphide and cadmium selenide for the photosensitive elements.

The upper end of the spout is provided with upper and lower internal circumferential beads 14 and 15 of triangular and semi-circular cross-sectional shape, respectively, and the plug bead 25 lies below the bead 15 in the retracted secured position of the spout. The upper rims of the spout and plug are provided with flanges 12 and 24 and the lower portion 10 of the spout tapers from its free end towards the upper end for wedging engagement with the opening-defining web 6 on withdrawal of the spout, an end stop flange 11 being provided.

The plug bead initially moves past the lower spout bead and enters a depression 16 between the spout beads. Continued upward pulling raises the spout until stop flange 11 engages the edge of the opening. Further upward pulling on the finger grip removes the plug from the spout. Closure is effected by reversing the procedure.
