Title: Preparation of bis p-ethylbenzylidene sorbitol
Inventor: SASAGAWA KATSUYOSHI
IPC: C07D493/04
Filed: 1980-07-08
Abstract: PURPOSE: To obtain the titled compound useful as a clarifier for synthetic resins through a method with an easy separation of a reaction product in high purity and in high yield, by reacting sorbitol with an aldehyde in a specific ratio in an organic solvent, followed by removing the solvent through the azeotropic distillation of the solvent and water.  
     CONSTITUTION: 1 Mole sorbitol and 1.6W2.2mol P-ethylbenzaldehyde are condensed through dehydration in an organic solvent (e.g., benzene, cyclohexane, etc.) to be subjected to azeotropic distillation with water. The reaction is carried out in the presence of an acid catalyst, e.g., sulfuric acid, etc. under reflux by heating, and the formed condensed water is distilled away out of the reaction system. A slightly alkaline aqueous solution at pH 7.1W9.0 is added to the reaction solution, which is heated to distill away the organic solvent as an azeotropic mixture with water. Since just before the organic solvent is almost completely distilled away, the powdered solid material of the titled compound shown by the formula is floated, it can be separated from the reaction solution by an extremely simple method, e.g., filtration, etc.

Title: Turret tool rest
Inventor: ARII SEIJI
IPC: B23B29/32
Filed: 1985-05-01
Abstract: PURPOSE:To simplify the structure of a turret tool rest thereby making easier to mount tools thereon by mounting a turret indexed by rotation on the turret tool rest body through a coupling and positioning driving mechanisms outside the outer diameter of the coupling. CONSTITUTION:Each housing 45 for driving mechanism is fixed and a driving axis, i.e. a clutch axis 46 is equipped corresponding to each working position on a turret body 21. A tool-side clutch 48 is connected to or disconnected from a driving clutch 48 of the clutch axis 46. As couplings 30 and 31 couple each other and indexing finished, rotation of the clutch axis 46 becomes cutting rotation, and a preset cutting work starts. Since the driving mechanisms are positioned outside the outer diameter of the couplings 30, 31, it becomes easier to mount the tools to the turret tool rest.

Title: Oxygen detector and method of producing thereof
Inventor: EDOWAADO POORU HABUDASU
IPC: G01N27/407
Filed: 1980-07-09
Abstract: Oxygen sensor with a disc type solid electrolyte has the disc sealed in a shrinkable ceramic tube by the pressure which is developed and the surface glazing which takes place as the tube is fired. The tube is preferably formed of forsterite which can shrink about 25% during firing, thus causing the tube to become slightly bulged out in the region of the disc due to the interference fit produced by the shrinkage. The porous electrodes on the top and bottom surfaces of the disc are preferably omitted from a small region near one edge of the top and bottom surfaces but are continued as a stripe or band down the edge from a diametrically opposite portion of each surface, the stripes and unelectroded areas associated with the respective surfaces being spaced to prevent electrical shorting. The disc stripes are pressure bonded during firing of the tube to a pair of spaced lead stripes on the inside tube surface.
