Title: Mixer head for mixing two or more flowable materials
IPC: B01F23/47
Filed: 1975-04-01
Abstract: 1484751 Mixing head DESMA-WERKE GmbH 1 April 1975 [5 April 1974] 13298/75 Heading B1C A mixer head for mixing two flowable materials, e.g. for polyurethane mouldings, comprises a housing having a transverse bore to provide a mixing chamber 13, the two materials entering into said chamber 13 through nozzle bores 23, 24, and wherein the mixing chamber is variable in its volume by adjusting the position of an ejector plunger 25, and the angle of the nozzle bores 23, 24 relative to the axis of the outflow 14 of mixed material is either 90 transverse to said outflow or directed contrarily to said outflow direction. The materials are supplied through inlets in the housing and enter into flow passages 17, 18 of valve plungers 15, 16 via openings 21, 22 in the housing and slots 19, 20 in the valve plungers. The nozzle bores 23, 24 lead from the flow passages 17, 18 into the chamber 13. At the end of a mixing stage, the valve plungers 15, 16 are moved in unison so that nozzle bores 23, 24 move out of alignment with the chamber 13 and into alignment with openings 28, 29 which lead to return conduits so that a recirculating flow takes place. At this extended position of the plungers 15, 16 cut-outs 30, 31 are aligned with the chamber 13 to allow the ejector plunger 25 to pass through the mixing chamber. Adjustable means 32-37 allow the flow through the nozzle bores 23, 24 to be controlled. Each nozzle bore 23, 24 may be screw threaded to produce a rotary motion to the flow therethrough.

Patent GB-659953-A (GB)
Title: Improvements in thiophosphates
IPC: C07F9/18
Filed: 1949-05-20
Abstract: Thiophosphates of the formula <FORM:0659953/IV (b)/1> where R and R1 are alkyl groups of 1-6 carbon atoms, are obtained by heating PSCl2 with ROH in benzene to give PSCl2(OR), reacting the latter with the alkali metal derivative of R2OH in the presence of a lower alkanol to form PSCl(OR) (OR1), adding to the reaction mixture an alkali metal p-nitrophenolate and heating to produce the desired thiophosphate. In the first step, there are preferably used 10-12 mols. of ROH per mol. of PSCl2; the excess of alkanol and benzene may be recovered by fractional distillation and used in subsequent runs.  The second step is preferably carried out at 0 DEG  C. or below, using equimolecular proportions of reactants.  The product is not isolated, but an equimolecular proportion of alkali nitrophenolate is added and the mixture refluxed; the excess of alkanol from step 2 is then distilled off, the thiophosphate extracted with benzene and the latter removed by distillation. The alkali nitrophenolate used is preferably anhydrous, since the recovered alkanol does not then have to be dried, but the commercial dihydrate may be used if desired.  Examples show the use as ROH of methanol, ethanol, n-propanol and n-butanol, followed by reaction with sodium methoxide and sodium ethoxide. Tables show the insecticidal activities of the various products. Specification 644,616 is referred to.
