Title: Differential pressure switch - for controlling heating of fluids, measures pressure drop of flowing fluid
Inventor: AHLSWEDE HEINRICH
IPC: H01H35/40
Filed: 1973-08-02
Abstract: The technique is suitable for controlling the heating applied to flowing fluids, and hence the viscosity of these fluids. The pressure exerted by the flowing fluid is compared with a known pressure and accordingly the heating element is switched 'ON' or 'OFF'. Pressure comparison is made by connecting a rod between a chamber, containing the known pressure, and a second-chamber where the fluid to be measured is contained. The rod is allowed to move, and it will therefore adjust itself by moving axially so that the force exerted at each end of the rod will be equal. The rod controls the heating switch, to which it is coupled directly.

Title: Expansible rubber-sleeved distal end stopper for endoscope - giving smooth contour from stopper-end to body-tube with no ridge in between
IPC: A61B1/00
Filed: 1974-04-19
Abstract: The stopper on end-piece on a cleft metal tube covered by a rubber sleeve is passed on its rod through the body-tube of the endoscope. Turning the rod draws in a screw, thrusting the cleft metal tube over a conical wedge and so expanding it and its rubber sleeve covering up to the full diameter of the endoscope and eliminating any possible ridge at this point. Turning the rod back again allows the metal tube and its rubber sleeve to return to its original size, and permits the stopper to be withdrawn through the endoscope tube. In instruments requiring a twist action to secure the stopper to the body tube of the endoscope, the rotation of the rod would be incorporated with the twist into a single movement.

Title: Polyimides prodn by single-stage catalystic condensn - from diamines and tetra carboxylic acid dianhydrides
Inventor: KORSCHAK WASILIJ WLADIMIROWITS
IPC: C08G73/10
Filed: 1974-12-24
Abstract: Prepn. of polyimides by a single stage high temp. poly-condensn. at 100-200 degrees C of diamines and tetracarboxylic acid dianhydrides in an inert, immiscible with H2O, polar organic solvent, and in presence of a carboxylic acid catalyst, used in the ratio 0.25-10 pref. 0.8-2.5 - COOH gps. per polyimide member. As carboxylic acid catalyst an acid of the general formula: R(COOH)n is used, esp. acetic or benzoic or a tetracarboxylic acid; R is an aliphatic, aromatic or heterocyclic radical and n = 1-4. Polycondensation of diamines with 3, 31, 4, 41-benzophenonetetra-carboxylic acid dianhydride (I) occurs at 120 degrees - 140 degrees C; with 1,4,5,8-naphthalene tetracarboxylic acid dianhydride (II) reaction is carried out at 190-220 degrees C. As organic solvents, nitroaromatic hydrocarbons, aliphatic and aromatic chlor-hydrocarbons, or aromatic nitriles are useD. The advantage of the catalytic method used is an increase in reaction velocity thus allowing high mol. wt. polyimides to be prepd. at a lower temp. i.e., 100 degrees C, or to shorten reaction time to egg., 1 hr. Only the catalytic procedure allows linear, fusible, soluble and hardenable polyamides on the basis of (I) to be prepd., which are converted to an infusible, insoluble condition at 200-300 degrees C. A single stage process without catalyst results in a three dimensional insoluble prodt. High mol. wt. film forming polyimides using less reactive dianhydrides with 6 membered rings e.g., (II) can be prepd. (having a viscosity index = 1-2 dl./g.). Such polyimides e.g., polypyromellitic imides have significant heat and hydrolytic resistance. Polyimides prepd. by the catalytic process have mean mol. wT. = 50.103-200.103; viscosity index = 0.7-2.0 dl./g.; glass transition temp. 320 degrees - 520 degrees C; decompsn. begins at 450 degrees - 500 degrees C. They possess film and fibre forming props.
