Title: Improvements relating to automatic uncoupling for model railway stock
Inventor: FERNEE LEONARD ARTHUR
IPC: A63H19/18
Filed: 1960-03-09
Abstract: 910,196. Toys. WRENN Ltd., G. &. R. June 5, 1961 [March 9, 1960], No. 8229/60. Class 132 (3). Method of automatically uncoupling the vehicles of model railway rolling stock which consists in inserting in the rail track at requisite positions therealong between the rails a track unit for creating a magnetic field whereby the fingers of automatic couplings comprising two interengaging hook-like members pivoting in a plane parallel to the track and having a downwardly depending finger are attracted to a position which moves the couplings into disengagement when the coupling tension is relieved. The track unit comprises an elongated permanent magnet 5 mounted upon a strip 6 of insulating material secured to the track by fixing screws or the like. If the track has a central conducting rail, which is cut away to insert the magnet, copper terminal-pieces 7 are inserted between the magnet 5 and strip 6 for joining the ends of the rail. Further packing 11 may be inserted below the strip. The projecting nose of the coupling hook-like projection 1 operates between a pair of stops to prevent swinging movement of the coupling device. An electromagnet may be used which may be controlled by a switch.

Title: Improvements relating to automatic weighing machines
IPC: G01G13/00
Filed: 1922-03-22
Abstract: 200,877. Garratt, C. F. March 22, 1922. Automatic-feed weighers. - In an automatic weighing-machine employing horizontally movable main and dribble feed valves, a vertical main shaft beneath the valves is provided at its upper end with means for opening and closing the main valve, and an automatic clutch is provided for engaging and disengaging the valve-operating shaft to and from a continuously rotating source of motion, means actuated from the dribble feed valve being provided for controlling the clutch and the discharge door of the weigh pan. An electric motor 3 drives a shaft 4 passing through the vertical valve-operating shaft p which is driven by the engagement of a toothed clutch member 5 on the shaft 4 with a pivoted catch 7 on the shaft p. Assuming the catch 7 to be in engagement with the clutch member 5, the shaft p rotates, and bv means of an arm q draws back the main valve h into the open position shown. The dribble feed valve l slides in guides beneath the main valve and is carried back when the main valve opens. The material from the hopper b runs freely into the weigh pan d until the continued rotation of the arm q moves the main valve again into the closed position. The size of the feed orifice j is adjustable to regulate the quantity of material thus delivered. At the end of the closing movement of the main valve the catch 7 comes in contact with a lever 8 and is thus liberated from the clutch member 5, and the shaft p is consequently arrested. Material flows through a dribble aperture k, the dribble valve l being retained by a catch t. When the weight has been made up the weigh beam c tips and closes the circuit of an electromagnet w which releases the catch t and allows the dribble valve to close under spring action. A projection 13 on the dribble valve rocks a lever 9 and (1) opens the discharge gate e of the weigh pan by means of a rod 14 and spring- controlled striker 16, (2) withdraws the lever 8 so as to allow the clutch parts 5, 7 to re-engage and again rotate the shaft p to commence another cycle of operations. The discharge gate e automatically closes under its counterweight. To prevent tilting of the beam as the main feed is delivered, a projection on the main feed gate engages an abutment on the rear of the beam. A stop 28 limits the return movement of the beam. Stirring devices. A uniform flow from the supply hopper is maintained by. a stirrer 18 driven by bevel wheels from the shaft 4. A change-speed gear 20 may be provided to vary the speed to suit different requirements. An additional stirrer 25 may be provided within the hopper.

Abstract: 704,618. Weighing apparatus. LINDARS, H. April 7, 1952 [April 11, 1951], No. 8430/51. Class 143 [Also in Group XXXVIII] For dispensing measured quantities a switch 129 or 130 at a remote point is closed to drive a motor 121 in the appropriate sense. The motor, through a Selsyn system 133, 134, drives a weight indicator 122 at the remote point, the operated switch 129 or 130 being opened to stop the motor when the desired weight to be dispensed is indicated. The motor will at the same time, (see Group XXXVIII), have driven the counterpoise trolley 22 through the endless chain 30 to a corresponding position along the weighbeam 17 and rocked the latter to close contacts 118 to light a signal lamp 199 indicating that dispensing may commence. A switch 115 is now closed manually to energize a magnet 110 thereby opening a spring-biased shutter 109 in the feed from the hopper 107 and a series lamp 116 lights to indicate that dispensing is in operation. When the load dispensed reaches the value indicated, the weighbeam first rocks to neutral, thereby opening contacts 118 to extinguish lamp 119 and then opens contacts 114 to de-energize magnet 110 to cut off the feed. The operator now releases switch 115 and when the scale pan 106 is emptied the consequential closing of the contacts 114, 118 and lighting of lamp 119 indicates that a further quantity may be dispensed.

Title: Manufacture of tetra-(carboxymethyl)-1:2-diamino-cyclohexanes
IPC: D06P1/647
Filed: 1948-03-23
Abstract: 1 : 2-Diaminocyclohexyl derivatives of formula <FORM:0651990/IV (b)/1> where A is cyclohexyl or an alkyl substitution derivative thereof, or their alkali metal salts, are prepared by treating a cyclohexyl-1 : 2-diamino compound with at least 4 molecular proportions of an acetic acid derivative containing a reactive substituent in the a -position and a free carboxylic or a modified carboxylic group which may be converted to a carboxylic group, e.g. an ester, amide, nitrile, or a salt group, or alternatively the cyanohydrin of formaldehyde.  When present, the modified carboxylic group is subsequently hydrolysed by acid or alkaline hydrolysis.  The cyclohexyl ring may be substituted, for example, by methyl, n-propyl, dimethyl or n-butyl groups.  The diamines are prepared from anthranilic acid alkyl esters by reduction with sodium to 1-aminocyclohexyl-2-carboxylic acid esters, the amides of which are prepared by the usual methods and subjected to the Hofmann degradation to give the amines.  In the examples: (1) chloracetic acid in excess caustic soda solution is warmed with 1 : 2-diaminocyclohexane to give after acidification, 1 : 2-diaminocyclohexane-N,N1-tetra-acetic acid; (2) and (3) the cyanohydrin of formaldehyde (formed in situ) is used in place of chloroacetic acid as in (1) to give 1 : 2-diaminocyclohexane tetra - acetonitrile, which is hydrolysed in alkaline solution to the salt of the tetra-acid.

Title: Method and apparatus for the separation or fractionation of material dissolved or suspended in a liquid
IPC: D21D5/02
Filed: 1966-02-28
Abstract: 1,144,243. Treating water. AXEL JOHNSON INSTITUTET FOR INDUSTRIFORSKNING. 28 Feb., 1966 [1 March, 1965], No. 8627/66. Heading C1C. [Also in Division B2] A method of separating or fractionating material(s) suspended or dissolved in a liquid comprises flowing a charge of the liquid, preceded and followed by a gas, through a channel whereby a concentration effect is obtained in the liquid as a consequence of the relative movement between the liquid and the channel, and progressively collecting the charge of liquid as it issues from the channel as two or more separate fractions. The method is applicable to the separation or fractionation of material(s) when suspended in a liquid; the separation of material from a liquid in which the material is suspended or dissolved; and the fractionation of a suspension or solution of material(s) in a liquid. In Fig. 1 a liquid suspension is introduced into an inlet chamber 1 and passes through a nest 2 of inclined tubes 14 in which fractionation takes place, the different fractions being collected in a collec - tor 3. The tubes are mounted in an end plate 2<SP>1</SP> and in an end wall 13 of the chamber 1. The chamber 1, the end plate 2<SP>1</SP> and the tubes rotate with a shaft 4 rotatably supported in bearings in brackets 9, 10. The collector 3 is stationary and is urged by a spring 6 against a flange of the end plate 2<SP>1</SP>. The collector, Fig. 4, is divided internally into a number of compartments 15 by adjustable walls or scraper elements 16. In operation, the suspension to be treated enters the chamber 1 via an opening 12 and is maintained at a certain level therein so that there is space above the suspension for a gas, e.g. air. During rotation, the tubes become filled with plugs of suspension separated by the gas. As the plugs flow down the pipes, the concentration of material in suspension increases in the forward portion of each plug and gradually diminishes towards the trailing portion. Fractions of different concentrations delivered from the tubes are collected in the various compartments 15 and are discharged through pipes 19. Instead of the inclined arrangement, the shaft 4 and the tubes 14 may be horizontal and the inlet chamber 1 may be internally pressurized to give forced flow of liquid suspension through the tubes 14. In another embodiment, Fig. 5, a helical tube 32 is mounted on a rotatable inclined shaft 35, the lower end 33 of the tube at each revolution dipping into suspension contained in a vessel so that each turn of the helical tube becomes filled partly with air and partly with suspension. A collector is arranged at the upper end 34 of the helical tube for collecting the different fractions.
