A new betaine salt corresponding to the formula is disclosed. It is obtained in pure crystalline form by preparing a starting aqueous solution containing the ions Na+ and Cl- whose composition, as illustrated in a ternary diagram of betaine-NaCl-water shown in the drawing, is situated in an area between two lines diverging from a common point T and passing through the points...

PURPOSE:To make the structure of a speed change gear to a compact size and to balance the right and left weights by supporting an intermediate shaft on an upper crank case and a crankshaft and a main shaft on a joining surface portion, respectively. CONSTITUTION:An intermediate shaft 4 is supported by an upper crank case 12, and a countershaft 7 is supported by a lower crank case 13. A crankshaft ...

PURPOSE:To prevent oil from being excessively agitated by the rotary part of a transmission gear and to prevent a rise in temperature and deterioration of oil and an increase in the fuel cost, by controlling the level of the transmission gear oil in an oil sump according to a car speed. CONSTITUTION:When a car speed is low, the governor pressure from a governor 34 is also low, thereby the spool 84...

The lace will have at least one portion in which the unitary elements from which it is made up are drawn together and adhere to one another. The unitary elements of the laces (8) are drawn together by means of the lace being pulled between the two pairs of rollers (11) and (12) and (9) and (10) and then being welded at least on the surface by means of hot air and, finally, being cut. The invention...

Chemical demolition is brought about by a water/powder product which is placed in pre-drilled holes, which dry product comprises burnt lime with slaking retarding agents, Portland cement and plasticizer. The expansion of the lime is retarded to such a degree, that at water addition the cement has time to stabilize to a solid body in the entire mixture, placed for example in a predrilled hole befor...

A series of 4''-deoxy-4''-amino-erythromycin A antibacterial agents and their preparation from erythromycin A via 4''-deoxy-4''-oxo-erythromycin A intermediates.

PURPOSE:To crush an empty can easily with weak force by a simple device, by relieving the structural stress in the end plate parts of the metallic empty can then crushing the cylindrical part. CONSTITUTION:End plate parts 1 of an empty can made of metal are first blanked round by cutting or pressing to relieve the structural stress that the parts 1 exert on a cylindrical part 2 in the stage of cru...

The invention relates to an arrangement for the compensation of thermally induced displacements of work spindles on processing and fabricating machines, in particular machine tools, as a result of thermal deformations at the sub-assemblies of the work-spindle bearings or at the headstocks. The aim of the invention is to achieve a high accuracy of the axial position of work spindles with little tec...

It is the aim of the invention to process all influencing variables acting on the sliding characteristic of guides by circuit means in such a manner that a long service life of the guides is made possible with uninterrupted multi-shift operation. According to the invention, a circuit arrangement is provided which detects the individual and/or total power dissipation of all or of selected elements ...

PURPOSE:To efficiently utilize a high temp. heat source by arranging metallic hydrides in the order of dropping hydrogen releasing temp. and heating them in the order to cause thermal decomposition. CONSTITUTION:MgNiH2, TiCoH2 and LaNi5H6 as metallic hydrides A, B, C are filled into divided chambers 1, 2, 3, respectively. A high temp. heat medium H is introduced into a divided chamber 4 from a lin...

PURPOSE:To aim at the improvement in reliability without use of any pressure source of hydraulic pressure, besides serving as a braking system to a rectilinear motion, by installing valves into a part of closed-loop passages, while making a slide so as to be effectively braked by blocking up these valves. CONSTITUTION:A piston 2 slides in a cylinder 1. One end of a rod 3 is hinged by the piston 2 ...
