Abstract: A die arrangement for pressing, sintering or stamping comprising: a die body with a cavity extending from an opening at a first end of said die body to an opening at a second end of said die body, and one or more moving parts arranged around the opening at said first end of said die body, wherein each moving part is displaceable between a first position and a second position. The die body may be configurable to receive a die plunger at said second end of said die body, said plunger being displaceable within the cavity.

Abstract: The device (9) has a pair of rounded triangular ends 8 mm thick (10) joined by a wooden handle (12). One side of each end is cut out to 3 mm, depth (13). This is the side of the end which rests on top of the ruler. The other side of each end is flat (14). The ends are connected by two strips (15, 16) 6 mm thick. Perpendicular to these strips are (2) reinforcing strips (17, 18) 6 mm thick. The strip (16) is affixed to the bottom of the flat side of each end to form a step (16). This is the strip which rests on the outside of the ruler. The strip (15) affixed to the bottom of the cut out side of each end. This is the strip which rests on top of the ruler. The underside of both strips have rubber feet affixed to them at 5-10 cm intervals. The handle (12) is 4.5 cm above the ruler (8) in order to enable visibility of the position of the fabric edge (7) and the ruler (8). The transparent quality of the device is a vital quality to the user.

Abstract: A thermal probe system has a Wollaston thermal sensor connected in one arm of a bridge. The other arms of the bridge are provided by resistors and a voltage is applied from a low-noise source via several op-amps. The output of the bridge is connected with a primary winding of a step-up transformer, the output of which connects with the input of an output amplifier, which, in turn, provides an output to a display.

Abstract: A puff tonometer includes two light sources located at diametrically opposite points, preferably equidistant from the optical axis of the objective lens assembly of the tonometer. The sources are arranged to direct light forwardly of the tonometer such that, in use, and when positioned close to a patient's eye under test, light from the two sources, after reflection by the anterior corneal surface of the eye under test, will be imaged by the objective lens assembly of the tonometer, to appear as two small areas of light in the field of view.

Abstract: The application discloses a fire protection cover for an electrical device recessed into a wall or ceiling, said, comprising one or more support layers coated with one or more layers of intumescent material. The device is especially useful for suspended ceilings or partition walls for preventing the passage of fire into or out of the ceiling or wall cavity. The cover may comprise one or more apertures to enable the cover to be ventilated and/or for access to cabling. In particular, the cover may be made of a mesh or perforated sheet. In the event of a fire, the intumescent material tumesces to block any holes within the cover or holes between the cover and wall or ceiling.
