[Class 105] [Also in Group XXXIV] To prevent false operation of a track relay by rail current induced by magnetic-brake shoes each brake shoe has a number of poles la, 2a, Fig. 5, arranged so as to set up opposite fluxes whereby the induction of any rail current is practically eliminated, or the brake shoes are provided with collector shoes 7, Fig. 3, interconnected by one or more electrical conductors of low resistance so as to form, with the portions of the rails on which the brake shoes bear, one or more closed circuits of low resistance thereby to short-circuit the induced current. The collector shoe 7 is pivoted at 9 and in addition to a spring 9a has a member 10 of magnetic material so that on energization of the brake shoe such member 10 will cause the collector shoe to bear firmly on the rail. Fig. 4 shows collector shoes 3 which are pressed on the rails by solenoids 11a energized simultaneously with the brake shoe 4. Collecting shoes on the same or different rails may be interconnected. Brakes shoes with magnetic plates moving into contact with the rail may also have conductor plates moving into contact with the rail.

Patent GB-697980-A (GB)
Title: Concentration process
IPC: C07B35/04
Filed: 1950-11-03
Abstract: Hydrocarbons containing more than one carbon atom or a mixture of such hydrocarbons are subjected to partial oxidation in the vapour phase with gaseous oxygen at elevated phase with gaseous oxygen at elevated temperature, the products are rapidly cooled to stop oxidation by an aqueous quenching medium, the temperature of which is raised during quenching to an extent such that most of the oxygen-containing compounds initially absorbed flash off and leave a formaldehyde solution containing minor quantities of other oxygen-containing compounds, the flashed-off compounds are absorbed in water, and the oxygen-containing compounds are separated from both the formaldehyde solution and the absorption p  product by distillations conducted while maintaining the pH of the contents of the distillation columns at not less than 4.0. Preferably, the quenching medium is circulated between the quenching zone and a cooling zone, and a side-stream is removed for distillation and replaced by an equal quantity of water, the pH of the returned quenching medium being adjusted to not less than 4.0, e.g. by caustic soda solution (cf. Specifications 668,931 and 697,906).  The pH of the formaldehyde solution and the absorption product are adjusted during distillation by adding to the reflux to the columns employed a solution of e.g. sodium acetate, phosphate, or phthalate, or potassium borate.  An example describes the oxidation of isobutane as above, and refers to a series of pressure and flush distillations of the formaldehyde solution and absorption during which the pH of the contents of the columns is adjusted with sodium acetate solution. Products specified besides formaldehyde are acetaldehyde and acrolein, formic acid, acetone, methyl ethyl ketone, methanol, butylene oxides, propylene oxide, tetrahydrofurane.
