PURPOSE:To reduce the heat generation at an operated part, to dispense with a cutting piece 3 and to cause a bone conglutination to be satisfactory by providing an engrave-shave blade to receive an impact with the collision of a piston sliding in an air room. CONSTITUTION:A compressed air passes an air tube 5, flows into an air room 4, works a shoulder part 6 and causes a piston 2 to retreat. When...

PURPOSE:To press the bleeding blood vessel of a bone cutting edge and to block a blood vessel internal cavity by composing a working part of an impact hitting tool. CONSTITUTION:An impact hitting tool 1 is provided to a main body 3 having a piston 2 to slide in an air room 4. A compressed air passes an air tube 5, flows into the air room 4, works to a shoulder part 6 and causes the piston 2 to ret...

PURPOSE:To almost uniformize the depth of a hardened layer on the upper and lower sides of a part of a crankshaft to be heated by applying more current to the lower side than to the upper side by the amt. corresponding to the heat loss from the mass on the lower side. CONSTITUTION:When the pin 12 of a crankshaft 10 is at its highest position, the center 21 is situated at point C, and the shaft 10 ...

A temperature control system for dispensing installations in maintaining different types of liquids at different temperatures includes feeding from container to dispenser each different type of liquid through pipe bundles (14, 16) insulated from each other. Each bundle (14, 16) has a cold water pipe (18) passing therethrough. The cold water pipes (18) are in circuit with a cold water supply. Tempe...

A stereophonic sound reproduction system is aimed at synthesizing at a multiplicity of points (L) in the listening space. An auditory effect obtaining at corresponding points (K) in the recording space, to compensate for crosstalk (C21, C12) between the loudspeakers, the acoustic response of the listening space, and imperfections in the frequency response of the speaker channels. Each speaker chan...

The present invention relates to an arrangement for suspension of a baking furnace (19) for continuous production of carbon electrodes in direct connection with the smelting furnace (2) wherein the electrodes are consumed. The baking furnace is suspended from a baking furnace frame (15) by means of at least three rails (16), said rails (16) being connected to the baking furnace frame (15) at their...

Determn. of two or more analytes in a liq. sample is effected by: (a) loading ligands specific for each analyte onto a support in discrete locations such that each location has not more than 0.1 V/K moles of ligand, where V (litres) is the vol. of the sample and K (l/mole) is the equilibrium constant of the ligand for the analyte; (b) contacting the support with the sample; and (c) measuring the a...
