Title: High sensitivity miniature electromagnetic relay
Inventor: ELDRIDGE PETER GORDON
IPC: H01H50/18
Filed: 1984-11-07
Abstract: A miniature electromagnetic relay has an energising winding (1 ), an armature (2) extending through the winding (1), and a yoke arrangement (3, 4 and 5) which extends through the winding (3 and 4) and along the outside of the winding (5) and provides a pair of opposite polarity pole faces (4A and 5A) cooperating with one end (2A) of the armature and a second pair of opposite-polarity polefaces (3A, 5B) cooperating with the other end (2B) of the armature. One energisation of the winding the polefaces (3A, 4A) against which the armature is normally biassed in its rest position by a bias spring will have poles induced in them which are the same polarity as those induced by the adjacent ends of the armature, thus repelling the armature over its initial phase of movement. As the armature travels across towards the other pole face under magnetic attraction the repulsive force will weaken and the attractive force will become greater. However at any point over the travel of the armature, there will be a significant force on the armature, and this enables greater sensitivity and higher contact forces to be achieved. In the preferred embodiment the relay has four sets of changeover contacts. The relay has a low profile and a DIL footprint. <IMAGE>

Title: Intraocular implant
Inventor: RICHARD ALBERT R
IPC: A61F2/16
Filed: 1985-04-17
Abstract: An intraocular implant of the type having a lens (12) and one or more flexible lens retaining legs (16) extending therefrom for seating in an eye chamber, in which the free end of at least one of the legs (16) has means for latching engagement with a co-operating latching portion (30) on the periphery (14) of the lens, which is so positioned circumferentially on the peripheral portion that when the end of the leg is latched therein, the leg is flexed around the edge of the peripheral portion so that the lateral dimension of the implant is substantially no greater than that of the lens and peripheral portion alone thereby facilitating insertion of the implant through an incision into the eye. Preferably the peripheral portion of the lens body has an upwardly projecting leg support member against which the leg bears when it is flexed around the lens body, which controls the amount of bending of the leg and distributes the bending throughout a substantial portion of the length of the leg. <IMAGE>

Patent GB-2203964-A (GB)
Title: Ion exchange process
Inventor: GONZALEZ MANUEL OLIVO
IPC: B01J47/10
Filed: 1988-03-17
Abstract: A process for obtaining dissolved salts and acids from other available ones, by means of ion exchanging resins, is done in two stages, placing the changing resin in columns 10, 20. In the first stage the resin 10 is charged with the cation corresponding to the salt which it is desired to obtain by passing a solution of a suitable salt through the resin. The resin thus charged is cyclically extracted from the column 10 at the same time that it is replaced by regenerated resin from the second stage of the process. Before making the resin used in the first stage 10 pass to the second 20, it is released from the salt solution with which it was charged (at 14), by means of draining and washing with water, or by shifting with another solution. In the second stage of the process, the resin 20 is regenerated by having it pass through a solution of a salt or an acid, the anion of which is the one corresponding to the salt which it is desired to obtain. <IMAGE>

Patent GB-2220454-A (GB)
Title: Blind rivet
Inventor: LACEY RAYMOND DENNIS
IPC: F16B19/10
Filed: 1988-05-27
Abstract: A blind rivet able to be anchored in material such as softwood, without the need to break through the blind face (36) of the material, comprises a tubular shell (14) and a stem (15) which extends through the shell. The shell (14) has a preformed head (18) at one end of a shank (17). An end portion (19) of the shank remote from the head (18) has a thinner wall (21) than the main, next adjacent, portion of the shank, and is thus weakened and made more easily expandible. The stem (15) has a plugging portion (28) having an expander head (29) adjacent the thin-walled end portion 19) of the shell, a breakneck (27), and a pulling portion (26) which projects from the head end of the shell. The expander head (29) increases in diameter away from the pulling portion (26), and presents a plurality of longitudinal cutting elements (24) generally towards the weakened end portion (19) of the shell. On gripping the pulling portion (26) and pulling the stem (15), the cutting elements split the end portion (19) of the shell into a plurality of legs (37), while the expander head (29) enters into the end portion (19) and forces the legs (37) outwardly. The main part of the shank (17) has a smaller diameter bore (20) than the weakened end portion (19), and resists entry of the expander head (29).

IPC: B29C48/475
Filed: 1988-07-14
Abstract: A method of controlling the wall thickness of a parison for a blow-moulding operation, during the extrusion of the parison, employs a die 10 having a movable plug 15 controllable to adjust the die gap.
