[Also in Division A2] In making a transparent, edible film, e.g. for wrapping and packaging foods, an aqueous solution containing 2 to 50%, by weight of gelatine, casein or albumin is mixed, at a temperature between 25 degrees and 60‹ C., with 5 to 70% of an innocuous plasticizer, such as glycerol, sorbitol or xylitol, and with 0.01 to 20% of dialdehyde starch, based on the dry weight of gelatine, casein or albumin. Reticulation of the gelatine, casein or albumin occurs due to reaction between its amino groups and the aldehydic groups of the dialdehyde starch. The resulting mixture is cooled to a temperature between 20‹ and 35‹ C. and spread on a supporting surface to form a film, which is dried at room temperature and then at 40‹ to 100‹ C., e.g. in hot air, and finally detached from the supporting surface.

[Class 59] In a jet pulverizer in which material is projected onto a fixed impact member by gaseous fluid issuing from a nozzle in which substantially the entire transformation of potential energy into kinetic energy takes place, the narrowest cross section of the nozzle is varied by a body or pin, preferably conical, which is adjustable in the axial direction of the nozzle. In Fig. 3 air enters at orifice 7 and after passing through a nozzle 2 picks up coal, fed in through orifice 11, and projects it through mixing pipe 8 onto an impact block 10, the fines being carried out through orifice 13. The flow of air or gas through the nozzle 2 is controlled by a member 3 movable by hand wheel 6. The member may be attached to a piston 23, Fig. 4, in a cylinder 24, the movement of the plug being controlled by the differential pressure produced by an adjustable spring 25 and a steam pressure admitted at 26, the steam being tapped off, for example, from the nozzle chamber of a steam turbine which drives the air compressor. In Fig. 5 the nozzle 30 is controlled by a member 31 attached to a solenoid 34, the current through which varies with the current to the motor driving the pulverizer compressor. The mixing tube 35 is connected by pivoted lever 37, link 38 and pivoted lever 39 with the member 31 to control the flow of coal to the nozzle. The member 31 may be actuated by a thermostat located in the furnace, or by a relay or servomotor.

Title: Improvements in or relating to glues and the application thereof
IPC: C09J7/21
Filed: 1932-09-05
Abstract: A dry flexible adhesive film consists of bone glue or a mixture of bone and hide glues.  Small quantities of potato starch may be added. The film may be made by milling a viscous glue composition between rollers.  The adhesive film may be reinforced with paper or fabric by immersing the latter in the liquid glue composition and subsequently drying.  In uniting pieces of wood, for example in veneering, heat and pressure are used to transform the film into a viscous mass which sets on cooling.  Glycerine, glucose and potassium lactate may be added to the composition to promote the change to a viscous state.

Abstract: 336,043. Avery, Ltd., W. & T., and Benton, W. A. Aug. 14, 1929. Addition to 320,416. Specific - gravity estimating-apparatus. - Apparatus for determining the specific-gravity of solids or liquids comprises a weighing resistant, such as a spring, provided with an index, a straight-line indicator also having an index, means for bringing the two said indices into register for indicating the weight in air position, a slidable member having an index adapted to be set to the weight in water position and an adjustable member adapted to intersect the straight line indicator for equating to unity the difference between the weights in air and in water, and for indicating specific gravity in terms of length on the straight line indicator. In the form shown in Fig. 1, which is particularly intended for determining the specific gravity of liquids, the solid body 6 is suspended from the spring 7 carrying the index 8 and the graduated straight line indicator 10 having the index 10<a> is adjusted to the position determined by the weight in air of the body 6, the indices 8, 10<a> being then brought into register by turning the adjusting-screw 7a. The body 6 is then immersed in water in the vessel 12 and the slide 15 carrying the pivoted member 14 is adjusted vertically by the knob 11 until the index 14a thereon registers with the new position of the index 8. The member 14 is then adjusted about its pivot 14b until its upper edge intersects the scale 10 at the graduation 1.0, and is clamped to the member 15. The body 6 is then immersed in the liquid of which the specificgravity is required and the slide 15 is adjusted vertically until the index 14a registers with the new position of the index 8. The intersection of the upper edge of the member 14 with the scale 10 then shows the; specific-gravity of the liquid. Another form for measuring the specific-gravity of solids heavier than water is described in which the scale arm 10 is horizontal. A third form is also described for measuring the specific-gravity of solids lighter than water. In this form the adjustable slide 15 is provided with an additional vertical bar carrying an index mark.
