Abstract: 1377284 Car-hire systems L M H SCHIMMELPENNINCK 29 Feb 1972 [4 March 1971] 9241/72 Heading G4T A number of car-hire stations, at any of which a car may be collected at the start of a journey or returned at the end of a journey, are all connected by communication links to a central control. A user of the system presents himself at his chosen starting station and, via the link from this station, informs the central control of his identity (e.g. by means of a personal punched card), and of his chosen destination station (e.g. by closing a corresponding one of a number of contacts). On the request being accepted by the central control, the latter may initiate the delivery of a car key to the user from a magazine of keys at the starting station. On arriving at the destination station, the user reports himself to the central control, e.g. by merely deliverying the car key to a device linked to the central control. The cars may be electrically driven, in which case their batteries may be automatically re-charged when the car is returned to the car stand at each station, contact with a charging means being automatically made when the car is positioned on the stand. If the central control senses a shortage of cars at a particular station, it may automatically couple one or more cars to a car from another station which is bound for the station suffering from the shortage. The duration of hire may be registered by the central control and a charge applied to the user's account.

Title: Improvements in or relating to the production of articles from synthetic resinous materials
Inventor: EVANS CYRIL GEORGE
IPC: C08J5/24
Filed: 1948-04-02
Abstract: Laminated or composite articles permeated with synthetic resins are produced by impregnating masses of permeable reinforcing material, e.g. asbestos, with synthetic resins, further impregnating one mass with a meta hydroxy phenol and another mass with an aldehyde, bringing the masses into contact so that the aldehyde and phenol will form a resin in both masses and curing the resin.  Phenol-, cresol-, and urea-aldehyde resins may be used as the initial impregnant.  In an example, two pieces of asbestos felt are impregnated with a partially condensed phenolformaldehyde resin and alcohol; one felt is also impregnated with resorcinol and the other with paraformaldehyde. After adjusting the flexibility by controlled evaporation of alcohol or by spraying with water the pieces of impregnated felt are heated to 100 DEG  C. while in contact under pressure.  Alternative meta-hydroxy phenols and aldehydes are phloroglucinol and pyrogallol, and furfural and crotonaldehyde respectively.
