Title: Multiple position linear actuator - has cylinder housing intermediate hollow piston in turn housing independent piston
IPC: F15B11/12
Filed: 1975-02-26
Abstract: An actuator where precise positioning is required e.g. to operate a linear or rotary door opening device, and which gives four distinct operating positions, has a standard cylinder inside which travels a piston which is hollow, and itself acts as a cylinder and encloses a further piston. This inner piston has a piston rod extending from the ends and projecting from the end caps of the outer cylinder. These piston rods are hollow and have connections for pressure medium to pass through and enter the chambers of the intermediate piston/cylinder. The end caps of the outer casing also have connections for pressure medium.

Title: Rust inhibiting coatings for steel - comprising cement and water with added plastic dried in air before setting, then set and hardened under water
IPC: C04B40/02
Filed: 1976-03-11
Abstract: Rust inhibiting coatings for steel surfaces which in service come into contact with moisture or are immersed in water, esp. drinking water pipes, are prepd. by use of a paste, applicable by spraying, centrifuging etc. the coating consisting of cement, water and opt. sand, by a process in which immediately after applicn. of the coating the process of hydration and hardening is interrupted by air drying, esp. with warm air and only continued when the duct is full of water and completed progressively in its normal term. A plastic matl. is mixed in with the cement to prevent the cement particles from being washed away by the flowing water after introducing the steel pipe into the pipeline. When used for a drinking water supply pipe a burst pipe must be fixed quickly, so that a pipe coated according to the invention can be installed and the water set flowing again quickly without washing away the unset cement.

Title: Purificn. of hydrocarbons with sulphuric acid - with addn. of soluble low mol. wt. polymer to assist sepn.
IPC: C10G17/06
Filed: 1977-06-17
Abstract: Purification of petroleum hydrocarbons comprises treatment with sulphuric acid, with addn. of a low mol. wt. organic polymer soluble in the hydrocarbon. The polymer is pref. dissolved before adding the acid. The process is used for treatment of oil fractions to removed resins, asphalt, N cpd. olefins etc., improve colour and smell, raise viscosity index, acid grade, emulsification resistance, etc. Impurities and foreign matter condense into small flakes and then to a sludge, which is readily sepd. by settling.

For a given quality level, amt. of acid used and amt. of alumina in subsequent purificn. can be reduced. The sludge contg. the polymer can be used after neutralisation as a prim. binder for asphalt, alumina, pyrophillite, etc.
