Patent number: 4979645Abstract: A system for introducing a flowable additive (3) from a capsule (1) to paint (4), varnish, woodstain or the like in a closed (preferably lidded) container (2) (for example a paint container) modified by the provision of a relatively easily openable inlet (9) into the container. Preferably the inlet is located in a lid (6). The capsule comprises a chamber (23) which defines a volume which contains the additive. The system is provided with means (25 and 34) for creating an opening in the chamber which can communicate with the inlet and means (preferably a compressible chamber) for positively expelling additive through the opening by contracting the volume which contains the additive. The capsule and container are also provided with co-operable locating means (10 and 30 with 25) which can co-operate to assist in locating the opening created in the chamber in communication with the inlet. Also a capsule and a closed container for use in the system and a method of introducing additive using the system.Type: GrantFiled: January 3, 1989Date of Patent: December 25, 1990Inventors: Michael H. Groves, Digby R. Redshaw, Michael R. Cane

Patent number: 4842415Abstract: A paint shaker (1) for use in in-store paint tinting operations comprising a platform (2) and clamping member (4) for accommodating a paint container (3) which is to be shaken wherein the shaker is provided with means for sensing resistance to downwards movement of the clamping member (4a or 34) and clamping member detection means (34) which do not allow the shaking operation to start until the container is clamped and the clamping member is in a pre-selected position chosen because it is a position that the clamping member must occupy if it is to clamp a container properly either directly or via a capsule from which colorant has been expelled.Type: GrantFiled: November 14, 1988Date of Patent: June 27, 1989Assignee: Imperial Chemical Industries plcInventors: Michael R. Cane, Michael H. Groves

Patent number: 4798287Abstract: A system for introducing additive (3) from a capsule (1) into a closed (preferably lidded) container (2) (for example a paint container) modified by the provision of a relatively easily openable inlet (9) into the container (2). Preferably the inlet (9) is located in a lid (6). Capsule (1) comprises a chamber (23) which contains the additive (3). The system is provided with means (25 and 34) for creating an opening in chamber (23) which can communicate with inlet (9) and means (preferably a compressibe chamber (23)) for expelling additive 3 through the opening. Capsule (1) and container (2) are also provided with co-operable locating means (10 and 24) which can co-operate to assist in locating the opening created in chamber (23) in communication with inlet 9. Also a capsule (1), a closed container (2) for use in the system and a method of introducing additive (3) using the system. Use of the system reduces the risk of spillage and splasing and is more suitable for use by inexperienced people.Type: GrantFiled: June 12, 1987Date of Patent: January 17, 1989Assignee: Imperial Chemical Industries plcInventors: Michael H. Groves, Digby R. Redshaw, Michael R. Cane

Patent number: 4395630Abstract: A measuring rule has a coilable steel measuring blade extensible through an opening in a housing and is marked along its length with regularly spaced dark areas separated by light areas. Two pairs of light sensors are located near the rule each associated with a light emitter. Each sensor is 180.degree. out of phase with the other sensor of the pair and 90.degree. out of phase with the other two sensors. The outputs of each pair of sensors are used to produce a difference signal. The difference signals are used by a counter to measure the magnitude and direction of movement of the blade. Each sensor output signal is divided by voltage divider to give a divided signal and each sensor output signal is compared with the complementary divided signal at the instant the difference signal of the other pair of sensors changes state and a fault signal is generated if its minimum is larger than the maximum of the complementary divided signal.Type: GrantFiled: January 19, 1981Date of Patent: July 26, 1983Assignee: Stanley Tools LimitedInventors: Paul N. Ramsden, Michael H. Groves
