Title: Evaporative counterflow heat exchange
Inventor: SCHINNER E
IPC: F28D5/00
Filed: 1979-07-05
Abstract: A counterflow evaporative heat exchanger comprises a vertical conduit (10) in which a coil assembly (16) is positioned. A fluid to be cooled or condensed passes through the coil assembly (16) while water is sprayed downwardly over it and air is blown upwardly through it. The coil assembly (16) comprises a plurality of tubes (66) which at each level in the assembly are spaced apart from each other in the horizontal direction by an amount greater than the diameter of the tubes. This has been found to improve heat transfer in comparison to counterflow evaporative heat exchangers using closely packed coil assemblies.

Title: Insert for ball nose end mill
Inventor: VOGEL SCOTT WILLIAM
IPC: B23C5/10
Filed: 1996-02-13
Abstract: An insert for use in a ball nose end mill is provided that includes an insert body having a top wall, a bottom wall, and at least one arcuate side wall. An arcuate cutting edge is defined at an intersection between the top and side walls that includes a plurality of sinusoidal undulations for reducing cutting forces, and vibration, and enhancing the breaking and removal of chips removed from a workpiece during a cutting operation. An end portion of the insert crosses the axis of rotation when the insert is mounted in the seat of an end mill body, and the undulations reduce the considerable shear forces applied to the cutting edge at this location. The cutting edge has a profile which follows the contour of a sphere to permit machining a rounded cut. The side wall of the insert body includes an upper relief portion disposed directly under the cutting edge, with a relief angle for preventing the undulations from making unwanted striations or tool marks in the sidewalls of the rounded cut.

Inventor: HASHIMOTO YUKIO
IPC: G04F5/06
Filed: 1974-10-24
Abstract: In addition to an oscillating circuit constructed as a clock pulse generator (91) and having a temperature frequency response as low as possible, the time-measuring instrument has a further oscillating circuit (92) which has a temperature frequency response deviating therefrom and preferably higher. A counter (98) counts the pulses of this further oscillating circuit and a temperature-dependent signal is formed by arranging for the counter results to be stored in a memory during a period which is essentially determined by a time counter (912) driven essentially by the clock pulse generator (91). Said signal is transmitted periodically to a frequency converter (91) whose output signal is used to correct the signal transmitted by the clock pulse generator to a reduction mechanism (911) which drives the time counter (912). At least some of the said circuit parts consist of CMOS integrated circuits. <IMAGE>

Abstract: A process is described for making sterically stabilised non-aqueous dispersions of composite polymer microparticles, in which (1) monomers including at least one crosslinking monomer are polymerised in an aqueous medium at a temperature at least 10° higher than the glass transition temperature of the polymer to be formed, in the presence of a block or graft copolymer stabilising agent, under conditions such that there is at no time present a separate monomer phase, (2) further monomers, not including any crosslinking monomer, are polymerised in the dispersion thus obtained, the presence of a separate monomer phase again being avoided, and (3) the microparticles are transferred from the resulting dispersion into a non-aqueous medium which is a solvent for the non-cross- linked polymer generated in (2). The microparticles are of value for incorporation into coating compositions the main film-forming constituent of which is compatible with the non-cross- linked component of the particles.
