Title: Preparation of phenol ether derivatives
Inventor: IPPOLITO ROBERT MAURICE
IPC: C07D263/06
Filed: 1987-02-25
Abstract: Phenol ethers of formula:   <IMAGE> wherein m is 2-5; n is 1-4; R is a C3-4 branched alkyl or C3-4 cycloalkyl, are prepared from p-hydroxyphenethyl alcohol by first reacting at the phenolic group, with epichlorohydrin followed by an appropriate amine,to prepare the required secondary amine-hydroxy side chain. Protection of the alcoholic group is not required during these steps. Then the secondary amine-alcohol group is protected by reaction with a suitable aldehyde such as benzaldehyde to form an oxazolidine ring protectant whilst the alcohol chain is elaborated. The oxazolidine ring protectant is removed by simple acid hydrolysis. The above ethers may be converted to any desired pharmaceutically acceptable salts. <IMAGE>

Title: Automatic retractable fluid delivery valve
Inventor: COURAGE JOHN BENJAMIN
IPC: B05B15/74
Filed: 1990-02-22
Abstract: A fluid delivery valve comprises a hollow needle attached to a spring-loaded piston slidable in a cylinder. The needle at one end extends through an aperture in the bottom of the cylinder and at the other end through an axial aperture in the piston. The spring-loading is such as to urge the piston towards the top of the cylinder. Oil is fed under pressure through an inlet orifice in the top end of the cylinder into the cylinder and forces the piston down against the spring-loading and the needle through the aperture in the bottom of the cylinder, simultaneously forcing oil through the bore in the needle. On cessation of the oil supply, the spring forces the piston up, retracts the needle. The inlet orifice may offset from the bore in the needle so that the orifice is closed off by the piston when the needle retracts. <IMAGE>

Patent GB-2248485-A (GB)
Title: Rotary valve.
Inventor: EMERY JAMES A
IPC: F16K31/04
Filed: 1990-10-04
Abstract: A sealed valve body housing a rotary valve rotated by a spindle. The spindle is connected to a disc mounted in a chamber in the valve body adjacent a valve body wall. Polyphase drive coils on the valve body wall induce a current in the disc, causing it to rotate. A pulse sensor mounted on the valve body detects the rotative position of the disc and a counter signals the power source to stop movement of the valve. The periphery of the disc is notched to permit the pulses to pass through the rotating disc and be counted. The torque of the disc can be increased through use of more sets of coils, more discs or gears interconnecting the spindle and the rotary valve.
