Patent GB-2286628-A (GB)
Title: Oven door latches
Inventor: BRETHERICK ALAN HAROLD
IPC: E05C3/14
Filed: 1995-01-20
Abstract: An oven door, for example for or of a continuously fired oven, has a latch member (17) which is sprung to an operative position for engagement with a keeper (15). The spring loading is preferably provided by a coiled spring (27), in the illustrated embodiment a sear spring, which is located about a pivot pin (18) of the latch member and has one end acting on the door and the other on the latch member, conveniently at a projection (20) on its member which engages with stop means (25) at the door to limit the pivotal movement of the latch member. The keeper may be variably set for co-operation with the latch member. The provision of the spring-urged latch member avoids the usual need for the oven door to have loose hinges and to be bodily lifted or tilted to engage and release the latch member from the keeper. <IMAGE>

Title: Yarn brake means
Inventor: HORVATH ATTILA
IPC: B65H59/16
Filed: 1995-03-17
Abstract: A yarn brake (8) has two brake disks (9), supported rotably and with axial play in a bearing means (20), which are retained against one another via resiliently yielding means, such as permanent magnets (29) or springs. Via an oscillatory motion generating means, such as an electromagnet (33, 35), mechanical or other means, the bearing means is set into mechanical oscillation that is essentially axial to the brake disks. The brake disks are carried along only slightly or not at all by the oscillating bearing means oscillatory motion generating means but the oscillation not only overcomes the static friction between the brake disks and the bearing means but also averts contamination of the contact faces between the brake disks and the bearing means. The bearing means may comprise one or two pins (24) engaging the disks externally while a yarn deflection pin (26) penetrates their central openings. A single bearing pin, with or without a separate deflection pin, may alternatively pass through the openings. <IMAGE>

Title: Method of separating a solute from other solutes
Inventor: WATKINSON JOANNE LOUISE
IPC: B01D61/04
Filed: 1995-05-04
Abstract: A method of separating a solute from one or more other solutes in a solution comprises insolubilising the solute to be separated from the solution, and passing the insolubilised solute and the remaining solution in contact with a membrane. The insoluble particles cannot pass through the membrane filter but the solute(s) remaining in solution pass through the membrane filter and are thus separated from the insoluble particles. This method is particularly suitable in the manufacture of N-acyl taurate derivatives, and especially in the manufacture of sodium N-cocoyl, N-methyl taurate.

Title: Moving filter with elongate flow channel
Inventor: KEEPING SEAN
IPC: B01D63/16
Filed: 1997-10-09
Abstract: A filter assembly 10 arranged to reduce the effects of clogging comprises a filter element 14 in contact with a contaminated source on one side and in contact with a filter holder 12 on the other to define an elongate flow channel 16, motion of the assembly moving the filtered fluid along the flow channel towards a collection chamber 26. The elongate channel may be in the form of a spiral or helix (fig 3), and the filter holder may be disc shaped, and capable of rotation. The assembly may be used to obtain liquid samples from waste water heavily contaminated with suspended solid material, the filter disc being immersed in the waste water at a depth sufficient to cause filtration due to hydrodynamic effect. Rotation of the filter assembly then causes the filtered fluid to move along the elongate flow channel towards the centre of the disc, and into the collection chamber. Periodically fluid accumulated within the collection chamber is withdrawn through a collection tube (28, fig 2) connected to a pump. Alternatively, the filter holder may be cylindrical, with the flow channel in the form of a helical groove on the cylinder surface.
