Abstract: ABSTRACT It is known to rapidly and almost completely remove solvents from protein material using direct steam.  This process subjects the protein to temperatures at which it becomes denatured, resulting in change of colouration and texture, and loss of coagulation and water retention properties.  These changes make the resulting material unusable in foodstuffs.  The present invention relates to a method of treating protein material with air, saturated with water, having a sufficient energy to evaporate the solvent while at the same time water condenses from the air replacing the evaporated solvent, thus overcoming the drawbacks of the prior methods.

Abstract: ABSTRACT OF THE DISCLOSURE          The radiation source frame of a gamma irradiating apparatus is moved into and out of its operative position by elevator means comprising block and tackle and an act-uating servo-motor, the servo-motor being operatively ass-ociated with the load or slow-motion and of the block and tackle, while the frame is operatively connected with the fast or force-end of the block and tackle.  The servo-motor is a pneumatic or hydraulic piston-cylinder motor, the supply line of which is arranged to be gradually throttled when the pis-ton of the motor reaches its end position corresponding to a screened position of the frame.  The arrangement thus pro-vides for a relatively rapid but still retarded downward movement of the frame in emergency cases, the movement being further retarded by the said throttling effect.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention provides a process for producing pure racemic acid and mesotartaric acid by reacting alkali maleates with aqueous hydrogen peroxide in the presence of alkali tungstate, in which the molar ratio of hydrogen peroxide to maleic acid is greater than 1, the alkali salts of the cis-epoxy succinic acid so obtained together with the alkali tungstate are converted into the free epoxy succinic acid and the free tungstate acid by passing them over a strongly acid cation exchanger and the free cis-epoxy succinic acid is hydrolysed to racemic acid and mesot-artaric acid in the absence of free tungstic acid which is removed with an anion exchanger prior to hydrolysis in the case of a catalyst-free hydrolysis or in the presence of free tungstic acid which is removed by an anion exchanger after the hydrolysis in the case of a catalyst-containing hydrolysis, the racemic acid is crystallized from the tungstic-acid-free hydrolysis mixture.          The mesotartaric acid remaining in the mother liquor is recovered therefrom either by crystallization or by evaporating to dryness and the anion exchanger changed with tungstic acid is regenerated with dilute alkali liquor.

Abstract: WATER MATTRESS AND METHOD OF MANUFACTURE                 Abstract of the Disclosure An improved water mattress can be fabricated by a method which involves folding a rectangular sheet of thermal plastic material into a smaller rectangular sheet to form a dual-layered sandwich having three open edges; thereafter lap-sealing these three open raw edges to form a flat closed envelope, open at its corners; subsequently cutting specific sized rectangular notches in each corner of the envelope whereby the several apexes of each notch can be separated to  form an overlapping slit which is reinforced with a sepa-rate piece of vinyl that is integrally bonded with the laps of the slit while it is in its stretched condition to com-pletely seal the mattress.  More specifically, sealing the open corners, after they are notched, is accomplished by stretching them over a small elongated oval die sufficient to cause the edges of the resulting slit to overlap slightly whereby an elongated reinforcing piece of vinyl can be lapped therewith and can be thermally welded with these overlapping edges to form a reinforced corner seam when all laps are welded simultaneously.  After the last corner is properly sealed, the small, oval-shaped or elongated die can be re-moved through a plastic valve incorporated in one of the sur-faces which is used to fill the resulting parallelepiped envelope forming the mattress.

Abstract: Abstract Of The Disclosure The switch includes a generally J-shaped, bimetallic switch arm having two, spaced, parallel legs, one of which is longer than the other.  The shorter leg is welded at its outer end to a metal boss, which is formed on the face of a mounting bracket, and thus supports the longer leg above the face of the bracket so that a first contact on the outer end of the longer leg overlies, and is normally engaged with, a second contact, which is mounted on said bracket to be insulated therefrom.  The high expansion side of the switch arm faces downwardly to confront the bracket, and since the shorter leg responds more rapidly to temperature changes than the longer leg, it tends to resist move-ment of the longer leg between open and closed positions and there-by prolongs the time the switch arm remains in either position.
