A screen, e.g. that of a C.R.T. or an electroluminescent device, is divided into discrete areas or elements, each of which is associated with a corresponding magnetic core in a core matrix or counter. A number of windings are threaded through the core matrix or counter, each winding being coupled only to those cores which are associated with the elements which are required to glow to produce a corresponding character display. In one embodiment, the cores are switched over in turn, and one of the windings is selected to apply the appropriate pulse train to the display device as the elements are scanned in synchronism with the cores. In another embodiment, a pulse is applied to a selected one of the windings to switch over only those cores corresponding to the character to be displayed, and the cores are then scanned so that only those cores which are switched back to their original state induce pulses in the windings for application to the display device.

Title: Gamma-hydroxy quaternary ammonium compounds
IPC: C07D295/084
Filed: 1952-05-06
Abstract: The invention comprises compounds of the formula <FORM:0733357/IV (b)/1> in which R is an alkyl (having up to 10 carbon atoms), cycloaliphatic, aralkyl or aryl radical, R1 is an alkyl (having up to 10 carbon atoms), aralkyl, allyl or cinnamyl radical, NA is a secondary amine residue and X is an anion.  Such compounds are obtained by reacting a g -hydroxy-tertiary amine with a quaternizing agent of the formula R1X in which R1 has the meaning heretofore described and X is for example halide or methylsulphate.  A quaternary ammonium bromide or iodide may be converted to the corresponding hydroxide by treatment in aqueous solution with silver oxide.  The hydroxide may then be neutralized with another acid, e.g. phosphoric, to give a product with the corresponding radical at X. Anions derived from inorganic acids, carboxylic acids and sulphonic acids are preferred.  In an example (1) 1-phenyl-1-isopropyl-4-dimethylamino-2-butanol is converted to 3-hydroxy-5-methyl - 4 - phenylhexyltrimethylammonium iodide. This product is converted to the corresponding quaternary ammonium hydroxide, portions of which are neutralized with phosphoric, acetic, sulphuric, p-toluenesulphonic and benzoic acids respectively. Similarly prepared are (2) 1-(3-hydroxy-5-methyl-4-phenylhexyl) - 1 - methylpiperidinium iodide; (3) 4 - cyclohexyl - 3 - hydroxy - 4 - phenylbutyl - trimethyl - ammonium iodide; (4) 3-hydroxy - 4,5 - diphenylamyltrimethyl - ammonium iodide; (5) 3 - hydroxy - 4 - phenylhexyltrimethylammonium iodide; (6) 1-methyl - 1 - (3 - hydroxy - 4,4 - diphenylbutyl)-piperidinium iodide; (7) 1 - (4,5 - diphenyl - 3-hydroxyamyl) - 1 - methyl - piperidinium iodide; (8) 1 - ethyl - 1 - (3 - hydroxy - 5-methyl - 4 - phenylhexyl) - piperidinium iodide; (9) 1 - benzyl - 1 - (3 - hydroxy - 5 - methyl - 4-phenylhexyl) - piperidinium bromide; (10) 3-hydroxy - 5 - methyl - 4 - phenylhexyltrimethylammonium methylsulphate; (11) 3 - hydroxy4 - phenylheptyltrimethylammonium methylsulphate; (12) 1 - (3 - hydroxy - 5 - methyl - 4-phenylhexyl) - 1 - cinnamylpiperidinium bromide; (13) 1 - (3 - hydroxy - 5 - methyl - 4-phenylhexyl) - 1 - allylpiperidinium bromide.  1 - Isopropyl - 1 - phenyl - 4 - (1 - piperidyl)-2-butanol used as starting material in example (2) is obtained by reduction with a platinum oxide catalyst of 1-isopropyl-1-phenyl-4-(1-piperidyl) - 2 - butanone hydrochloride (prepared by the Mannich reaction from 3-phenyl-4-methyl - 2 - pentanone, paraformaldehyde and piperidine hydrochloride).

Abstract: 796,303. Stud and socket fastenings; locking bolt.like pins. PALNUT, C. April 16, 1956, No. 11546/56. Classes 44 and 89(1) [Also in Groups XXIV and XXXIV] A metal push-on fastener for attachment over the end of a stud, shaft or the like comprises a sleeve having an integral flange extending radially of one end, a number of teeth being formed from the sleeve and having their roots integral with the flange, the teeth being relatively inflexible and extending inwardly of the sleeve at an acute angle thereto, slits being formed in the flange extending laterally from each side of the base of each tooth and so arranged that outward displacement of the free ends of the teeth causes the portion of the flange adjacent the slits to twist. As shown, the fastener is used to retain a wheel 21 on a doll's pram and comprises a cup-like body 10, an end-wall 12 and a flange 14. A pair of fingers 15, 15 is struck from the body 10 and a slit 17 is formed in the flange at each side of the root of each finger. The arrangement is such that when the fastener is applied over the end of a wheel-carrying shaft 19, the fastener is retained by the gripping action of the fingers on the shaft due to slight twisting or dishing of those parts of the flange extending between the extremities of the slits 17. End-pressure by the wheel &c. 21 causes the fingers 15 to bite into the material of the shaft 19. Any movement of the wheel-hub towards the end of the shaft tends to flatten the dishedportion of the flange, which increases the gripping-action of the fingers 15, without any substantial distortion thereof. The fastener functions also as a hub-cap and the flange 14 serves as a shock-absorbing thrustwasher. The end wall 12 may be omitted and the fastener may be applied to retain a rotary or reciprocating member, (other than a vehicle wheel), on a shaft (see Group XXIV).

Abstract: 907,580. Electromagnetic relays. ENGLISH ELECTRIC CO. Ltd. April 7, 1959 [April 11, 1958], No. 11555/58. Class 38 (5). [Also in Group XXXV] A relay device has a first or energizing electric circuit, a separate second electric circuit comprising a normally open contact system controlled by the first circuit, and capacitive circuit means associated with said second circuit for supplementing the contact closing force following initial contact closure. In Fig. 1, the rectified difference-current from two signals e1 e2 energizes a polarized relay coil 10a to close contacts 10b completing a trip circuit 11 and causing a capacitor 15 to discharge through the primary of a transformer 14 to increase the current in the winding 10a and hence the contact pressure. When contacts 10b open, the capacitor recharges and creates an impulse in the coil 10a assisting the opening force. In Fig. 2, the contacts 16c are closed by the energization of a first winding 16a and the capacitor 15 discharges through a second winding 16b which assists the first.

Water sampling apparatus for taking from a flowing stream a sample of volume proportional to the volume flow of the stream comprises mechanism controlling a sampling device 1, the mechanism comprising (a) a drum 17 rotatable at constant speed having opaque and transparent areas A, B bounded by a curve representing the functional dependence of the rate of flow of the stream upon its depth, (b) a helically-threaded screw rotatable by a pulley 22 and a cable 23 inter-connecting a float 24 and counterweight 25 so as to displace a nut 26 parallel to the axis of the drum 17 in proportion to the depth of the stream and (c) a fixed light source inside the drum 17 and a photo-electric cell 16 carried by the nut 26 and in circuit with a relay to control actuation of the sampling device 1. The drum 17 is driven by a constant speed motor and the sampling device 1 may be a peristaltic pump comprising a motor for driving a transverse arm 3 supporting rollers 4, 5 cooperating with a flexible pipe 6 one end 7 of which is immersed in the liquid to be sampled, its other end discharging into a collecting flask 9. Two modes of operation are suggested: (a) in a single continuous revolution of the drum 17 the cell 16 scans the opaque area once to switch the pump on for a period depending on the longitudinal position of the cell which position is determined by the depth sensed by the float 24 so that the period is proportional to the volume flow and (b) in a predetermined number of reversals in the direction of rotation of the motor 18 (arranged to occur each time the relay 13 is energized) the opaque area is repeatedly scanned, controlling the pump to operate for a period proportional to the volume flow. Given the co-efficient of proportionality between the volume of a sample and the volume flow of the stream the total quantities of materials carried in suspension and in solution can be calculated after analyzing the samples.
