Title: Polyurea dispersions in organic isocyanates
Inventor: HUGHES JEFFREY
IPC: C08G18/78
Filed: 1983-08-23
Abstract: A dispersion of a polyurea in an aromatic polyisocyanate is prepared by mixing the polyisocyanate with one or more aliphatic diprimary diamines having (a) at least one amine group attached to a carbon atom having not more than one hydrogen atom attached thereto or (b) at least one amine group attached to a carbon atom which is itself attached to a carbon atom having not more than one hydrogen atom attached thereto, provided that both amine groups are not attached directly to separate rings of an alkylene-linked polycyclic aliphatic ring system. The reaction preferably takes place at a temperaure in the range 20°C to 60°C. The polyurea dispersion products are useful for manufacture of polyurethane foams and elastomers of superior physical properties.

Patent GB-2172125-A (GB)
Title: Opto hydraulic servo valve
Inventor: BREWSTER ARTHUR EDWARD
IPC: F15C1/04
Filed: 1985-03-07
Abstract: To operate a hydraulic valve in a dangerous environment, optical signals are conveyed to the valve via optical fibres (3, 4). At the receiving end, the optical signals are aimed at solar cells (1, 2), one of which responds to energize the valve's operating coil (2). Separate fibre- solar cell combinations are provided for opening and closing the valve. In an alternative where there is no magnet, the valve's control member is a flapper with a light-absorbent layer on each face. Each fibre, one for on and one for off, is aimed at one of the layers, so that the direction of movement of the flapper depends on which fibre delivers a signal. Such a signal when absorbed by one of the layers heats it and causes the flapper to bend to exert the desired control. The flapper co- operates with control nozzles to operate the valve. <IMAGE>

Title: Apparatus for orienting containers
Inventor: CLAYPOOL M P
IPC: B65G47/244
Filed: 1986-07-22
Abstract: A container orienting apparatus suitable for tasks and other non-cylindrical containers (12) comprises a pair of continuously moving counter-rotating parallel belts (80,90) for engaging opposite sides of the finish and/or neck of each container and for rotating each container a predetermined amount by changing the relative speeds of the belts for a predetermined time period. The amount of rotation necessary to rotate each container to a common orientation is determined by a programmable control means (24) responsive to orientation sensors (111) which determine which one of a number of natural preorientations each container has been brought to by preorienting means (106, 108) prior to engagement by the belts. User operated means allows a user to preprogramme the control means (24) to designate the rotations which are to correspond to particular output signals of the sensors (111). <IMAGE>

Title: Force detection assembly
Inventor: SIMPSON-DAVIS RAYMOND WILLIAM
IPC: G06F3/033
Filed: 1987-01-20
Abstract: A force detection assembly comprises a substantially rigid plate 1 mounted on a support (4) such that the plate is spaced from the support. An optical signal generator located centrally at 6 between the plate and the support injects optical signals into at least three and preferably four optical fibres 3 which extend beneath respective knife edges (2) or a mask coupled to the plate 1. The light transmission in the fibres changes in proportion to an applied load e.g. from a pen. Optical signal receivers (8) are positioned to receive light which has passed along the optical fibres 3 and to generate corresponding electrical signals. A force monitoring system to which the assembly is connected can determine the position and magnitude of an applied force on the plate from the signals generated by the optical signal receivers. The assembly may be used in a signature verification system for a cash dispenser. <IMAGE>

Title: Treating heat shrinkable material
Inventor: SCAPOLI TIZIANO
IPC: B29C61/02
Filed: 1987-02-10
Abstract: Control of the shrink potential of heat-shrinkable tubing is effected by inflating the tubing between a movable pair of pinch rolls (5) and a static pair of outlet pinch rolls (7), heating a shrink-controlling encircling collar (6a, 6b) disposed between the inlet and outlet pinch rolls (5 and 7) in order to control the degree of partial shrink of the film passing over the bubble, followed by cooling. Adjustment of the pressure in the bubble is effected by moving the pinch rolls (5) towards and away from the shrink-controlling circling members (6a, 6b), in response to the sensor (3) detecting changes in width of the flat-folded heat-shrinkable tubing (1) coming from a supply roll (2) to be partially shrunk. <IMAGE>
