Filed: 1948-02-26
Abstract: 641,751. Electromagnetic switches. PRINTER'S PLANT, Ltd., and UFFINDELL, R. H. Feb. 26, 1948, No. 5730. [Class 38(v)] In a solenoid controlled switch, a solenoid is pivotally mounted on a horizontal axis normal to the solenoid axis so that the latter may be tilted one way or the other by movement of an armature slidably associated therewith, the solenoid being so wound that on energization, the armature is drawn to one end or the other to tilt the solenoid and operate a switch. Fig. 1 shows one embodiment wherein a brass tube 4A carrying two solenoid coils 7A, 8A, is pivotally mounted at 2A. The solid iron armature 1A is slidable to either end of the tube according to which coil is energized, the tube on tilting operating a mercury switch 10A. The coils may be arranged differentially as a single winding one part being of higher impedance than the other and the whole winding being normally energized. The armature is therefore maintained at the higher impedance end and is drawn to the other end to tilt the tube by shorting out said part of higher impedance. Alternatively a single centre-tapped winding may be employed.

Title: Polymerisation process
Inventor: WALL JAMES ESTILL
IPC: C08G2/10
Filed: 1965-02-10
Abstract: An oxymethylene polymer is produced from formaldehyde with intermediate formation of trioxane and its polymerization or copolymerization with another monomer by polymerizing the formaldehyde in an aqueous acid medium to trioxane, extracting the trioxane from the aqueous mixture containing unreacted formaldehyde by means of a water-immiscible organic solvent, polymerizing the trioxane dissolved in this solvent and recovering the polymer from the organic solvent which is recycled together with unreacted trioxane contained therein to an appropriate part of the system. The trioxane produced in the aqueous acid medium may be vaporized therefrom together with water and unreacted formaldehyde, the vapours fractionally condensed to give an aqueous solution of formaldehyde which is returned to the aqueous acid medium and a vaporous mixture of trioxane, water and formaldehyde which is subjected to treatment with the organic solvent to form a liquid trioxane-containing extract for polymerization. The organic solvent may be benzene, while sulphuric acid may be the formaldehyde trimerization catalyst and form trifluoride or its complexes.  The polymerization catalyst or specified comonomers are ethylene oxide and 1,3-dioxolane.  The polymerization catalyst may be neutralized, e.g. with n-butylamine.

Abstract: 1389005 Controlling fluid pressure brakes HOPE TECHNICAL DEVELOPMENTS Ltd 26 May 1972 [5 March 1971] 6102/71 Heading F2F A brake control device for use for example with an anti-jack knife device such as that disclosed in Specification 1,075,802 comprises a housing 10 containing a regulator valve 18 having its outlet connected to the inlet of a control valve 14 the outlet of which is connected to the anti-jack knife device, the inlet of the control valve 14 receiving working fluid with the pressure at the outlet being dependent on the control signal applied to the device so that during operation a residual pressure prevails in the control valve inlet in the absence of a control signal such pressure being less than the maximum pressure of the working fluid but being sufficient to operate the anti-jack knife device. A double piston 12 disposed in a cylinder 11 has a rod 13 forming a spool valve 14 biased by a spring 30 and a second double piston 20 in a cylinder 15 is separated from a piston 16 by a spring 17 the piston 16 receiving the end of a plunger 47 operating valve 18. Each cylinder has an inlet channel 19, 19<SP>1</SP> which can receive a pneumatic auxiliary pressure signal and an inlet 21, 21<SP>1</SP> which can receive a pneumatic service pressure signal. A further inlet channel 22 constantly exposed to compressed air at about 120 p.s.i. extends into the inlet of valve 18, the arrangement being such that leakage air passes through the valve and pressurized air at about 40 p.s.i. enters the chamber 80 and acts against the inner face of piston 16. A further channel 24 extends from chamber 80 to an inlet 70 of valve 14. When valve 18 is nominally closed there is thus a residual pressure of about 40 p.s.i. in the channel 24 which can be applied to the anti-jack knife device.
