Patent GB-838669-A (GB)
Title: Synthetic polyesters
Inventor: ROBERTS JOHN FRANCIS LLOYD
IPC: C08J3/14
Filed: 1957-10-30
Abstract: A finely-divided polyester, especially a polyethylene terephthalate, is made by dissolving the polyester in a halogenated lower fatty acid or an aqueous solution thereof containing at least 80% of halogenated fatty acid, and precipitating the polyester in finely-divided form by adding to the solution an aqueous solution of a halogenated lower fatty acid containing not more than 50% by weight of the halogenated fatty acid.  In the examples, the precipitated polyester is washed with water.  The halogenated fatty acid may be di- or trichloroacetic acid, trifluoroacetic acid, dichloropropionic acid or mixtures obtained by chlorinating acetic acid which may contain some free acetic acid.  The finely-divided polyester may be used as a moulding powder, or may be incorporated with a pigment, preferably before drying, to provide pigment mixtures suitable for the coloration of polyamides or polyesters (e.g. polyethylene terephthalate) or for the preparation of coating compositions for application to paper or textiles.

Title: Improvements in or relating to the control of the supply of liquid fuel to the air charge of internal combustion engines
IPC: F02D1/00
Filed: 1932-11-30
Abstract: 411,117. Regulating. RICARDO, H. R., 21, Suffolk Street, Pall Mall, London. Nov. 30, 1932, No. 33872. [Class 7 (vi).] In engines operating with spark ignition and wherein the liquid fuel is delivered by a metering pump into the air charge in each cylinder or in the inlet passage thereto, means are provided for controlling the quantity of fuel delivered in accordance with variations of pressure in the induction passage, and also for admitting some of the exhaust gases to the induction pipe when, for example in motor vehicles, the vehicle is overrunning the engine, so as to reduce the depression in the induction pipe and prevent an over-rich mixture from being supplied to the engine. Further, in order to provide a richer mixture when accelerating or hill-climbing, the hand control of the air throttle is so arranged that, in its final movement to open the throttle fully, it causes an enriching adjustment of the fuel pump. Fig. 1 shows the induction pipe B<1> connected to the cylinders by passages B, to which fuel is supplied by a pump F controlled by a piston H in a cylinder H<1> connected at H<2> to the induction pipe, the other side of the piston being open to the atmosphere. Springs J<1> normally maintain the piston H in the position shown, but its position is varied by alterations of induction-pipe pressure produced by adjustment of the air throttle C. The hand control C<1> of the throttle contacts with an extension K from the piston H when the throttle is fully open. The exhaust manifold D is connected by a pipe D<1> having a restriction D<2>, to the induction pipe, so that when overrunning occurs, some of the exhaust is drawn into the induction pipe. Alternatively, the supply of exhaust products to the induction pipe may be obtained by adjustment of the valve operation so that the inlet valve opens a little before the exhaust valve closes. Also the adjustment of the fuel pump by the throttle control at its fully open position may be effected by causing the latter to adjust the fulcrum of a lever which controls the pump. In a modification, the cylinder H<1> is connected with a Venturi contraction in the induction pipe, so that the fuel control is dependent on the rate of flow of air, as well as the pressure.
