Title: Process for purification of high boiling esters for removal of alcohols by plural stage distillation with steam or inert gas
IPC: C07C69/34
Filed: 1968-02-09
Abstract: The invention relates to a process of purifying high-boiling esters (boiling above 250 C.) obtained by esterifying an acid or acid anhydride with a molar excess of an alcohol having at least 4 carbon atoms followed by neutralizing and washing with water.

Thus, the process may comprise a first stripping effected under atmospheric or moderately raised pressure. a second stripping under moderate vacuum and a third stripping under high vacuum, or the second or third stripping may be omitted. Specified esters which may be treated include di-decyl phthalate, di-tridecyl phthalate, di-n-butyl phthalate, dihexyl phthalate, dioctyl phthalate and di-2-ethyl hexyl sebacate. Apparatus is described and examples are given. Specification 934,027 is referred to.

Title: Improvements in or relating to the continuous manufacture of extrusions
IPC: B29C48/30
Filed: 1968-05-22
Abstract: An extrusion moulding machine comprises a pressure-responsive device 27 adjacent the extrusion orifice and a valve 4 having a baffle 8 situated in the flow path of plasticized material and drivingly coupled to a diaphragm 20, forces on the diaphragm due to the baffle being counteracted by compressed gas delivered via conduit 23, an electrically controlled pressurecontrol system coupled with device 27 regulating the supply of compressed gas so as to tend to keep the sensed pressure constant. Baffle 8 is coupled to diaphragm 20 via a silicone grease plug which coacts with a piston 18 in a cylinder 17. In operation, device 27 converts pressure values into electrical signals which are conveyed to electromagnetic switches 30, Fig. 2, the sensing of a sufficiently high pressure creating an electric signal sufficient to operate the switches and to change the feed of compressed gas to conduit 23 from path a to path b. Valves 35, 36 are set at different values, valve 36 allowing a lower pressure to exist above diaphragm 20 which results in a rise of piston 18 and such movement is transmitted to baffle 8 by the silicone grease plug in conduit 10 to thereby reduce the flow of material to the extrusion orifice. Additionally a valve oscillator 24 is provided which maintains a relative high frequency, e.g. 30-60 c.p.m., but low amplitude gas pressure change, e.g. 0À1-0À2 atmos. above diaphragm 20. Such oscillation is transmitted to baffle 8 whose responsivity is thereby increased. Downstream of the die orifice is affixed, via a heat insulating ring 13, a cooling and sizing device 14, 15, Fig. 1. A grease gun 25, 26 communicates with conduit 10. The extrusion of one or more bars and sheets is mentioned with, in the case of a sheet, the possible use of a plurality of baffles 8. Polyamide resin is mentioned as an example of extrudable material.

Title: Ball valve having metal seat rings
IPC: F16K5/06
Filed: 1977-09-16
Abstract: This relates to a ball valve of the top entry non-spherical type. A soft metal coating is deposited on that portion of the seat ring which contacts the valve member or ball. The ball and seat assembly is inserted into a valve chamber such that the seat rings are in an unstressed condition.

Title: Method and circuit for producing measuring pulses in a particle analyzer
IPC: G01N15/12
Filed: 1978-07-18
Abstract: A method of, and circuit for, producing measuring pulses in a particle analyzer for the analysis of particles suspended in a liquid, especially blood cells, comprising a conductivity or measuring cell, whose impedance between two terminals of the conductivity cell changes upon passage of a particle through such conductivity cell. A controllable current supply powers the conductivity cell with a current regulated to maintain a reference value corresponding to a control value. A receiver functioning as a high-pass filter and having high input impedance serves for the essentially currentless removal of a potential between the terminals of the conductivity cell and for forming a receiver signal corresponding to such components of such potential whose frequency is above a threshold or cut-off frequency corresponding to the high-pass filter. The control value is formed from the sum of a predetermined reference value and the received signal. There is formed a measuring signal proportional to the difference of the control value and the reference value and whose timewise changes correspond to the measuring pulses.
