Patent GB-413628-A (GB)
Title: Improvements in the manufacture of plastic materials
IPC: C08G8/28
Filed: 1932-10-14
Abstract: Aromatic phenols such as cresol or phenol are condensed with aldehydes such as formaldehyde in the presence of condensing agents until after precipitation with acid, the plastic mass obtained is soluble in aqueous solutions of ammonia or its derivatives.  Suitable condensing-agents include alkali lyes or salts of strong bases with weak acids with or without the addition of sulphites, hyposulphites, or sulphoxylates.  The product, if desired with the addition of filling agents, polyhydric alcohols or compounds of ammonia or amines with formaldehyde may be hardened by heating.

Title: Improvements in hydraulic braking systems for vehicles
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/26
Filed: 1963-08-20
Abstract: 1,048,049. Hydraulic brakes; valves. GIRLING Ltd. July 23, 1964 [Aug. 20, 1963], No. 28825/63. Headings F2F and F2V. Means for controlling the hydraulic braking pressure supplied to different pairs or sets of vehicle wheels comprises a housing 10, an inlet 11 for connection to a master cylinder or other source of pressure, a first outlet 24 for connection to front wheel brakes, a second outlet 27 for connection to rear wheel brakes, a spring- loaded differential piston 13 working in a bore 12 of the housing between said inlet and first outlet adapted to raise the outlet pressure higher than the inlet pressure when the latter exceeds a predetermined value, and a plunger valve 29 adapted to cut-off communication between the inlet and second outlet when the inlet pressure exceeds another predetermined value. Normally, fluid passes from the inlet to the first outlet by way of an open valve 26 arranged in plunger working in a recess formed in the differential piston and to the second outlet by way of the unseated head 34 of the plunger valve and passage 28, the two outlet pressures being the same. At a predetermined inlet pressure, the differential piston is moved back against the bias of a spring 19 thereby allowing the valve 26 to close. The pressure supplied to the front brakes from the first outlet is then increased relative to the inlet pressure in proportion to the ratio of the areas of the working faces of the piston. At another predetermined inlet pressure, the plunger 29 is moved against the bias of a spring 31 and closes the communication between the inlet and second outlet, thereby preventing any further increase of fluid pressure supplied to the rear brakes. Though reference has been made to front and rear wheel brakes of a vehicle, the application is not limited to four-wheeled vehicles but may be applied to articulated lorries and other heavy vehicles.
