Patent GB-979977-A (GB)
Title: Basic lead salts of aromatic polycarboxylic acids and vinylhalide resin compositions containing such salts
IPC: C07C63/313
Filed: 1962-03-01
Abstract: The invention comprises basic lead salts of aromatic carboxylic acids having 3-6 carboxyl groups on the aromatic ring.  They may be prepared by forming a mixture of litharge, the aromatic polycarboxylic acid and an aqueous medium, the litharge being present in excess of the stoichiometric amount necessary to produce the normal salt, milling the mixture until the pH value remains constant, and then filtering and drying the product. Preferably an acidic catalyst such as acetic or nitric acid is added to the reaction slurry, e.g. 0.1-0.15 pounds of catalyst per 100 pounds of litharge used.  The basic lead salts may be incorporated as stabilizers in polyvinyl halide compositions.  The aromatic polybasic acid may be trimellitic, trimesic, hemimellitic, pyromellitic, mellophanic, prehnitic, benzene pentacarboxylic, or mellitic acid and the lead salt formed may be monobasic, dibasic, tri-, tetra-, or penta-basic. Examples of the preparation of basic lead salts of mellitic, hemimellitic, trimellitic, 5-hydroxy trimellitic, trimesic, and benzene pentacarboxylic acids are given. Specification 494,742 is referred to.ALSO:Basic lead salts of aromatic polycarboxylic acids having 3 to 6 carboxyl groups present in the ring are used as stabilizing agents in vinyl halide resins. The incorporation of these basic lead salts in the resin provides a good degree of heat stabilization with substantially no impairment of the inherent electrical resistivity of the resin, and, moreover, these salts stabilize the resin, after degradation has begun, in such a fashion that the resistivity of the composition remains at a high level. Vinyl halide resins specified are polyvinyl halides, co-polymers of vinyl halides with vinyl esters, co-polymers of vinyl halides with acrylic compounds, vinylidene halide resins and vinyl-vinylidene halide copolymers. The basic lead aromatic polycarboxylates may be used as the only stabilizing agents in the resin or in admixture with other stabilizing agents, and the total concentration of stabilizing agents present in the resin should preferably be in the range of 0.05-20% by weight of the resin. It is preferable to add the stabilizing agents at the initial mixing or milling stage of the resin. Examples are given illustrating the use of monobasic lead trimellitate; dibasic, tribasic and tetrabasic lead trimellitates, tetrabasic lead trimesate, tribasic lead benzene-tetracarboxylate, tribasic lead hemimellitate, and the basic lead salts of benzene pentacarboxylic acid and of mellitic acid as stabilizing agents in polyvinyl chloride compositions. Specification 494,742 is referred to.

Abstract: 704,503. Grater for soap &c. RITTER, E. April 1, 1952 [April 4, 1951], No. 8218/52. Class 28(2) In apparatus for grating soap, cheese &c. by a rotated grating disc 12 against which the soap in a cylindrical container 4 is fed by a screw-actuated pusher 10 when the hand-wheel 16 is rotated, the soap is in the form of a block 5 with a central bore for the screw 9 and with side grooves 7 to accommodate the inwardly projecting ribs 6 of the container, which ribs prevent the pusher plate 10 from rotating and so allow it to be fed down by the screw 9. The disc 12 is formed with scrapers 13 and with radial discharge slots 14 from which the shavings fall through a discharge opening 19 in the hand-wheel 16. The screw 9 has saw tooth or interrupted threads to prevent clogging. To insert soap &c. the handwheel 16 (and attached grater and screw 9 and pusher 10) is pulled downwards after removal of a set-screw 20 gripping a resilient ring 18 so that the soap can be placed on the screw 9, the whole then being pushed up inside the container 4. To avoid the need for unscrewing upwards the pusher for replenishment of a soap block, the pusher may be made in halves, separable by finger pieces and drawn together by springs.

Patent GB-587121-A (GB)
Title: Improvements in bulk evaporators
IPC: C13B25/06
Filed: 1944-05-02
Abstract: <PICT:0587121/III/1> The rate of delivery of heat to an evaporator of the sealed downtake type is controlled according to fluctuations in the liquor level in the evaporator.  Feed liquor from tank 27 passes through tube 2 into evaporator 1.  It rises through the tubes of calandria 3 and is heated therein by steam supplied through pipe 8. Sufficient vapour is formed at some distance up the tubes to lift the liquor to the top of the tubes and this distance defines the liquor level.  The concentrated liquor leaves the evaporator through downtake 4 and pipe 5 from which a bye-pass 6 leads through a hydrometer 7 or other device responsive to variations in density. The evaporator is connected above and below the calandria to a float chamber 12 of adjustable height which contains a float connected by linkage 13 to the steam control valve 9, either directly or indirectly through relay or servomotor means, so that an alteration in liquor level, due to fluctuations in feed rate, causes valves 9 to open or close in such a way as to arrest the change in liquor level. An independent control is obtained by connecting the displaceable element of densimeter 7 to valve 9 through linkage 25; this makes it possible to maintain the concentrated liquor at constant density. The vapour from the vapour space 10 may either pass freely to atmosphere through pipe 11 or be utilized in associated processes connected to pipe 11.  If, in the latter case, more vapour is required than can be supplied while yet maintaining a desired density of concentrated liquor, then extra water is added to the liquor supply tank 27 through pipe 26, the valve 28 in line 26 being regulated by control 12 so that the addition of water becomes effective when the liquor level in the evaporator falls below a predetermined level.  Should the demand for process vapour, however, be less than the rate of evaporation, then the excess is released to atmosphere through pipe 29 governed by valve 30 which is connected by linkage 31 to thermostat 32 disposed in the vapour space of the evaporator.  The invention is also described in regard to a quadruple effect evaporator to which heat is supplied in the form of steam at two different pressures, exhaust steam and live steam.  The admission of live steam is governed by a valve which is operated by a servo motor which is controlled by the liquor level in the first effect. The vapour pressure in the first effect may be limited by a thermostat disposed in vapour space of the effect, this thermostat being connected to the servomotor which operates the live steam valve. Specification 587,122 is referred to.

[Class 94 (i).] In order to facilitate access to the mechanism for applying adhesive to the wrappers in a machine for wrapping newspapers &c., the applying mechanism is arranged at the rear of the machine and the path of the wrappers is arranged accordingly. The paper is fed from a web 1 by rollers 2, 3 to a cutting knife 4 and the wrappers are received by rollers 5, 6, around which belts 7, 8 pass. The belts, with the wrappers between them, pass rollers 9, 10 and present the wrappers to a printing device 11, and thence pass rollers 12, 14, 15, 17<a>, 17b, 17 and 18. Between the rollers 15, 17<a>, the wrappers are brought over the applying device. The device comprises a table 24 mounted on a spindle 20 and carrying a container 16<a> in which a roller 16 rotates and transfers gum 16 to a roller 16b. The device is oscillated by a cam-operated bell-crank lever and link 33 so that the adhesive is applied to the wrappers at intervals. The gummed wrappers are delivered to the wrapping mechanism after passing the rollers 17, 18, where the tapes separate and return by separate paths. The tape 8 returns around rollers 22, 23 to the roller 6, and the tape 7 passes a roller 19 on its way back to the roller 5. Specification 107,238, [Class 94 (i)], is referred to.
