Title: Improvements in and relating to the manufacture of glues, gelatines, and the like
IPC: C09H3/02
Filed: 1929-03-07
Abstract: 324,461. Jahn, A. R. March 7, 1929. Glue; starch; gums, carbohydrate and like.- Glue is bleached by treating a glue liquor concentrated to 15-45 per cent with sodium hydrosulphite, with or without ammonium carbonate and/or borax. The treatment is effected by churning at a comparatively low temperature such as from jellying-point up to about 60‹ C. The gases liberated are. preferably retained in the body of the glue liquor whereby a glue of cellular or porous structure is obtained. By churning in an open vessel at a higher temperature e.g. 90‹ C., the gases may be largely eliminated to form glue of ordinary cake form. The process is applicable to liquid vegetable glues such as may be obtained from roasted starch products

Abstract: 936,241. Toy pistols. ADRIAN & RODE G.m.b.H. Oct. 13, 1959 [Dec. 16, 1958], No. 34703/59. Class 132 (3). A toy pistol for explosive corks comprises a revolver disc 6, Fig. 1, mounted on a spindle 5 so as to rotate in front of the barrel muzzle to bring the corks in turn and stepwise into firing position in front of a striker 9. The disc 6 is rotated by a trigger-operated slidable driver 40 engaging a toothed wheel 42, Fig. 3, on the spindle 5. On squeezing the trigger, the driver slides forward and a sloping surface 41 at its forward end acts on one of the teeth to rotate the spindle 5 and bring a cork into firing position. In this position, a spring-loaded lever 12, Fig. 7, acting on an arrestment wheel 10, also mounted on the spindle 5, tends to rotate the spindle further but this is prevented until the driver is withdrawn from between the teeth 43, Fig. 6, on the feed wheel since the driver is so shaped that it substantially fills the space between two adjacent teeth. During rotation of the disc 6 to bring a cork into line with the striker, the striker itself is being put under spring tension by a lug 46 linked with the trigger compressing a spring 27, the striker being retained by a detent arrangement 33, 34. On continued squeezing of the trigger, a pin 36<SP>1</SP> on the lug 46 bears on an inclined surface 47 to raise the striker and release it from its detent for firing. Forward movement of the striker is limited by an abutment 38. The striker 9 and driver 40 are returned to their initial positions by springs 35 and 45. When, on releasing the trigger, the driver is retracted from between the teeth 43 of wheel 42, Fig. 6, the spring- loaded lever 12, Fig. 7, bearing on the arrestment wheel 10 acts to complete a rotation of the spindle 5 through 90 degrees in preparation for further operation of the pistol.
