Title: Improvements in or relating to an automatic precision balance, with means for indicating and recording weight and price
IPC: G01G23/18
Filed: 1946-01-23
Abstract: 615,224. Weighing-apparatus. NICAISE, L. A. Jan. 23, 1946, No. 2278. Convention date, Aug. 27, 1945. [Class 143] An automatic balance for indicating and printing price, as well as weight, as determined by price rate keys t<1>-t<4>, comprises coaxial wheels 9, 51 for weight and price respectively, the weight wheel 9 being turned by an electric motor 8 to a position corresponding to that of the weight indicator dial 1 of the balance, whilst the price wheel 51 is turned by the weight wheel through the appropriate one of a series of gear trains (one shown at 64- 66) according to which of the price rate keys is depressed, each gear train having a clutch 57, 63 operable by a magnet e to bring it into gear upon actuation of a price key. The gear trains with their clutches and magnets are dispersed around the wheels 9 and 51, each clutch element 57 having teeth meshing with peripheral teeth 50 on the weight wheel 9, whilst the final wheel 66 of each train engages teeth 54 on the price wheel 51. Printing types 49, 53 are mounted on the wheel rims to print the weight and price on a ticket issued after each actuation. The price wheel also carries an indicator dial 52 concentric with the weight dial 45 of the balance. In operation, when the weight dial 45 has come to rest, the appropriate key t'-t', is depressed which energizes a magnet 5 to lock the dial and starts the motor 8 to drive the weight wheel 9, the motor circuit being broken by a magnet 11 when a contact 7 on the weight wheel catches up a contact 2 on the balance dial 1. The key t<1>-t<4> also energizes the corresponding magnet e to engage its gear train 61-64 so that the price wheel is driven by the weight wheel at a rate and to a position determined by the price key. The operator then presses a key 12 which energizes a motor 13 driving a wheel 14 provided with contact strips 15, 16 and 17 which act in succession, as the wheel turns, strip 15 to close the circuit of ticket printing magnets 18, 19, strip 16 to energize a reversing magnet 20 causing motor 8 to return the wheels 9 and 51 to zero, and strip 17 to stop motor 13 when the wheel 14 has completed one revolution. The circuit of magnet 20 is maintained at holding contacts until the wheels 9 and 51 have returned, when a cam 21 on wheel 9 rocks a switch 22 which energizes a magnet 23 to release a holding bar 28 for the keys. The depressed key is thus restored, and the main circuits are broken with all parts back to normal. A subsidiary key 25 is actuated instead of key 12 when a printed ticket is not required.

Abstract: 1,249,771. Sodium chloride. INTERNATIONAL SALT CO. 16 Jan., 1970 [25 Feb., 1969], No. 2318/70. Heading C1A. CaSO 4 -containing NaCl is purified by (1) forming a mother liquor consisting of NaClsaturated brine containing dissolved and undissolved CaSO 4 , and maintained at above 200‹ F.; (2) agglomerating undissolved CaSO 4  by adding a flocculant, and gravity-separating the agglomerate from the purified mother liquor; (3) cooling the purified mother liquor and separating recrystallized cubic NaCl therefrom. The residual liquor may be recycled to mix with source NaCl in forming the initial mother liquor. The purified mother liquor may be cooled by multi-effect evaporation, and hot vapours extracted at the various evaporation stages may be used to progressively heat the initial mother liquor. The flocculant may be used in an amount of 0À04-5À0 p.p.m. of brine. Apparatus is described, which enables the production of NaCl containing less than 1 p.p.m. CaSO 4 .

Title: Improvements in variable electric condensers
Filed: 1927-01-27
Abstract: 289,177. Lissen, Ltd., and Richardson, R. P. Jan. 27, 1927. Condensers of the type comprising two parallel metal plates 2, 8 with an interposed sheet of mica or other solid dielectric 4, and with a central threaded spindle 5 by rotation of which the plates are moved relatively to each other at right angles to their parallel surfaces against the action of a spring 9, one built in a case 1 of moulded insulation, the fixed electrode 2 being moulded into it. The case 1 may be of ebonite or bituminous composition and the foil plate 2 penetrates its wall at 3, the moving plate 8 being introduced in a heated condition so as to soften the insulation on which the sheet 2 beds and cause the sheet 2 and the insulation to conform to its shape. A bush 4, also moulded in the case, receives the spindle 5 which is threaded to engage the die cast moving plate. A dished spring 9, secured on studs 10 which are moulded in the case, has. arms 11 bearing in grooves 12 in the plate 8 to prevent it from rotating. The cover 13 is recessed at 19 to receive the end of the spindle, which is screwed and tapped and passes into a notched or serrated aperture in an arm 21 which is secured to the spindle by a screw 22. By slackening the screw 22 the split spindle contracts and the arm 21 can be turned one or more notches, thus altering the range of adjustment. The range is limited to just under a revolution by means of a pin 20 or moulded rib in the recess 19.

Abstract: 1376502 Moulding boxes AIRFIX INDUSTRIES Ltd 2 Jan 1973 [21 Jan 1972] 2992/72 Heading B5A [Also in Division B8] A container having inner and outer walls formed from a composite blank is made by inserting the blank into a mould 10, positioning a core tool 11 therein and joining the adjacent wall edges by injection moulding. The inner wall is then spaced from the outer wall by vacuum forming, blow moulding or a combination of both these methods. The blank is formed in a combined cutting and welding unit 6 in which the outer wall which may be paper, card or synthetic plastics foil and the inner wall which is of synthetic plastics sheet are fed from reels 7, 8 through guides 7a, 8a to the forming tool. When the tools 10, 11 are brought together material injected at 13, 14 seams together adjacent edges of the blank and a cavity 16 gives rise to a base rim on the container and a channel 19 forms a lip on the container mouth. A stripper plate 9 is provided. The inner wall is heated by the inherent heat of the tool or by heater elements therein either before, after and/or during the injection moulding operation. Formation of the inner wall occurs at a suitable moment either by injecting gas between the inner and outer walls through a hole at G formed by the cutting and welding unit 6 so that the inner wall conforms to the shape of the core tool or by applying a vacuum to passages 24 or by a combination of these methods. The material of the outer wall is chosen so that it withstands the heat necessary to form the inner wall.
