Patent GB-2157957-A (GB)
Title: Stretcher
Inventor: SHICKLE MARK
IPC: A61G1/01
Filed: 1984-04-17
Abstract: Stretchers, especially Neil Robertson stretchers, comprise a main canvas body (10) stiffened by slats (12) so as to act as a splint for the whole body and straps (14) either sewn or otherwise attached to each other to form a unitary harness are provided on the stretcher to strap the canvas body (10) around the casualty. These straps may comprise a main strap (14a) extending the full length of the stretcher and secured by sewing or other means to the canvas. The other straps may extend across this main strap like ribs or arms and are securely sewn to the main strap where they cross it. The straps therefore form a unitary harness with the result that their length is independent of their attachment to the canvas. <IMAGE>

Title: Image analyser
Inventor: WHITE COLIN ANDREW
IPC: G06T7/60
Filed: 1984-05-18
Abstract: An image analysis system (eg for determining fat in meat or cell analysis) has a T.V. camera 12 whose output is coupled to one input of a fast comparator 18. When the T.V. camera output exceeds the threshold value of the comparator, a clock is started whose pulses are counted at 26 until the output of the camera falls below the threshold value, in order to avoid the previous necessity of providing additional comparators when more than one threshold level is required analysis of the image, the other input of the comparator 18 is connected to the output of a digital to analog converter 20 whereby the threshold value of the single comparator is changed by the D/A converter under the control of a microprocessor at least once during an analysis cycle. With a monochrome image different threshold are used for alternate scans, and with a colour image the three colour signals are switched to the comparator on successive scans using different threshold levels. <IMAGE>

Title: Expelling contents of collapsible containers
Inventor: KNIERIEM GUNTHER
IPC: B05C17/005
Filed: 1984-09-13
Abstract: A collapsible container 10, containing a pasty material and having a nozzle 11 at its front end and closed rear end, is received in a reception means which consists of a rigid tubular body 8 open at both ends and enclosing an axially displaceable piston 9, which substantially fills the inside cross-sectional surface of the tubular body. The reception means with container inserted therein is removably received in a reception shell 4 of a dispenser gun. The gun piston 3 on the rod 2 bears on the displaceable piston 9 in the tubular reception means compressing the peripheral wall of the container 10 in concertina like manner and thus expelling the pasty material out through nozzle. By receiving the container in the tubular reception means 8 the peripheral wall of the container is prevented from moving laterally as it is compressed. The piston 9 is prevented from falling out of the tubular body 8 by reducing the diameter of the ends of the body 8, eg. by squeezing the ends. <IMAGE>

Title: Measuring the area of crista cutis
Inventor: ABE TAKEHIKO
IPC: A61B5/103
Filed: 1984-09-18
Abstract: By measuring the area of crista cutis the aging degree and condition of the skin may be judged. Utilizing a video camera 1 the skin surface is magnified 10-100 times and is projected on a monitor TV set 7, and video signals are also dual-valued by a video pattern sensor 11 to be projected on a monitor TV set 8 exclusively for the resulting black and white dual-valued video. The threshold is adjusted to show the crista cutis as white polygons surrounded by black lines of sulcus cutis, and as in this condition, crista cutis and sulcus cutis may not be entirely clear, the video is amended by the light pen (10) so as to accurately define the area of crista cutis. A computer 9 then calculates the area of crista cutis, taking into account the magnification. A fibre scope 5 provided with a light source may be attached to the camera 1. <IMAGE>

Title: Temperature sensors
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G01K5/18
Filed: 1985-02-23
Abstract: An optical fibre (3) extends through a capillary tube (1) coupled to a reservoir (2) containing a temperature responsive fluid (5) which extends along a length of the capillary tube predetermined by the temperature of the fluid. Optical power (6) is input to one fibre end and the amount of optical power output from the other fibre end is related to the fluid temperature. If the fibre is unclad and the fluid is mercury the transmitted power will increase with temperature increase, owing to the expansion of the mercury and the increased area of the reflective coating provided thereby for the fibre. <IMAGE>
