Filed: 1954-12-29
Abstract: 771,015. Electric toasters. MORPHYRICHARDS, Ltd. Dec. 19, 1955 [Dec. 29, 1954], No. 37547/54. Class 28(1) In an electric toaster having a bread holder movable from a delivery position, where it is shielded from the heating elements to a toasting position, means are provided for preventing the holder from moving to the toasting position until the heating elements and their associated parts have reached a predetermined temperature. As shown, framework 1 forms two toasting chambers each with two vertically disposed heating elements, rests on feet 18 and is enclosed by a casing 17 apertured to permit bread carriage 5 to move to and from its toasting position. Bread carriage 5 comprises two L-shaped members each consisting of arms 7 connected by wires secured to a shaft 9 rotatably supported in framework 1. One end of shaft 9 engages rotatably in a sleeve 14 projecting outside casing 17 and carrying a hand operating knob 15. An actuating arm 12 secured to sleeve 14 carries a cross pin 19 whose ends are adapted to engage respectively a lever 10 secured to shaft 9 and an arm 8 supported on sleeve 14. A helical wire spring 11 is engaged between parts 12 and 10 and a second spring 13 is engaged between arm 8 and framework 1. Adjustable timing mechanism 4 engages and retains arm 8 in the position 8a. The upper end of a lever 6 secured to shaft 9 engages a shoulder on arm 2 pivoted to framework 1. Arm 2 is spring biased upwardly clear of lever 6 but movement is limited by a bimetallic strip 3. To initiate toasting, knob 15 is turned through a right angle (clockwise, Fig. 1) thereby rotating sleeve 14 and arm 12 to load spring 11 and moving arm 8 to position 8a, where it is held by timer 4, thus stressing spring 13. Movement of the bread carriage is prevented by the engagement of lever 6 by arm 2 held by bimetal 3. When the toast chambers have reached a predetermined temperature, lever 6 is released and spring 11 rotates the toasting carriage into position, the timing mechanism being started at this point. After a predetermined time, timer 4 releases arm 8 which with the bread carriage, is returned by spring 13 to its original position

Title: Process for removing sodium chloride from aqueous caustic soda solutions
IPC: C01D1/38
Filed: 1957-12-04
Abstract: Sodium chloride is removed from aqueous caustic soda solution by osmosis employing as the membrane a synthetic resin in gel form swellable but insoluble in aqueous and alkaline media which resin contains polar groups; the opposite side of the membrane is in contact with water or a weaker pure caustic soda solution.  Resins referred to are condensation products of phenol or phenol sulphonic acid with aldhehydes and polar groups referred to are sulphonic acid, hydroxyl and carboxylic acid groups.  The artificial resins may be reinforced by inert synthetic resins or by asbestos or glass. According to an example, a phenol sulphonic acid is dissolved in a formaldehyde solution and the resulting solution employed to impregnate a polyvinyl chloride fabric, after which condensation is effected at 85 DEG C. in an atmosphere saturated with water vapour or by passage over steam heated rolls. The membrane is employed to purify industrial caustic soda.

Title: Improved process for recovering monomer fractions in the condensation of amino acids and other polyamide forming reactants
IPC: C08G69/04
Filed: 1956-12-18
Abstract: <PICT:0823735/IV (a)/1> In a process for making polyamides in which an aqueous solution or suspension of the monomer is subjected to vigorous heating, preferably in finely-divided form, causing a a rapid evolution of steam which entrains part of the monomer, and at the same time forming fused low polymer of which the condensation is completed in known manner, the monomer entrained by the steam is recovered by passing a current of said steam through a plurality of tortuous paths in a recovering space, keeping the steam at a temperature higher than the melting-point of the monomer, a major proportion of the monomer being retained in said space and recycled while the treated steam is discharged.  Stabilizers, e.g. ammonium stearate and pigments, e.g. titanium dioxide may be present in the starting materials.  In one embodiment of the invention, aminoundecanoic acid paste or hexamethylene diammonium adipate is charged into the mixing vessel 10 by aperture 12, water being added through 13 and stirring effected using the agitator 14 to produce a suspension or solution which is fed to the evaporator 20 and atomized by the rotating diffuser 24 which projects the resultant particles against the heating bodies 25 to produce a low polymer which is fed to the polymerization chamber 28 and further polymerized, the steam developed in the evaporator 20 being passed into the vessel 32 packed with Rasching rings retained on a grid or screen, the entrained monomer flowing down the rings and being returned to the evaporator 20.

Title: Improvements in and relating to cartons for cigarettes and the like
IPC: B65D85/10
Filed: 1929-12-17
Abstract: 347,201. Cigarette cartons. ROBINSON, H. G., Cote, Westbury-on-Trym, and ROBINSON, Ltd., E. S. & A., 1, Redcliffe Street, both in Bristol. Dec. 17, 1929, Nos. 38680/29 and 2112/30. [Class 18.] A carton of the slide and shell type comprising an open-ended shell for enclosing a plurality of rows of cigarettes or the like, one row in front of another. and having means sliding therein adapted to raise one row independently of another row is provided with a partition device for separating the rows of cigarettes, which device forms a part of the means for raising one row independently of another. The slide may be folded up from a single blank of material as shown in Fig. 1, to the form shown in Fig. 2. The portions 17, 18 are adapted to be folded together to form the partition between the rows of cigarettes, and if desired they may be secured together by adhesive. The part 16 must be left separate from the part 18. In operation both rows of cigarettes are pushed up from the bottom until the flap 10 projects from the top of the carton. Then by lightly gripping the sides of the carton and pulling on the flap 10, the bottom 15 of the rear compartment slides into line with the rear wall 13 of the slide, and the part 16 takes the place of the part 15 as the bottom of the rear compartment so that the rear row of cigarettes is caused to project beyond the front row. The top part 12 of the rear wall of the slide is not connected to the lateral wings 14, 14<1>, so that it may be bent back to allow both sides of the cigarettes to be gripped. Several modified forms of the blank are ;shown in which the wings 14, 141 and 21, 21<1> are connected to different parts of the blank and in some of which the wings 21, 21<1> are wide enough to extend right across the shell while in others they only extend half way across. In some cases the lateral wings 14, 14<1> may be dispensed with. If desired the blank may be severed across the hinge line between the sections 17, 18 so that the front and rear compartments are separate from one another. The two containers may be arranged back to back in the shell, their ends being secured to the inside of the shell. In this case each container has one of the wings 14, 14<1> extended to project out of the top of the container to form tabs. By pulling the appropriate tab the cigarettes in either row may be caused to project beyond those in the other row. In a further modification the two compartments are formed from separate blanks and are nested inside the shell and the inner container is raised by pulling on a separate flap with which it is provided. The partition forms a part of the inner container in this form.
