Patent ZA-853618-B (ZA)
Title: Method and device for press-forming sheet metal
Inventor: SMET GABRIEL DE
IPC: B21D24/04
Filed: 1985-05-14
Abstract: A sheet of metal of given thickness is press-formed to provide a part having a substantially constant thickness on a double action press. The sheet to be formed is disposed on a support. A first outer slide, or blank holder is applied on the peripheral portion of the sheet. A second central slide is applied on the central portion of the sheet. The peripheral portion of the sheet is formed while allowing it to slide under the blank holder, by displacing relative to said support at least one active part of the outer slide so as to compensate, in certain regions of the finished part, for excess areas of the sheet, for the given thickness of said sheet, relative to the volume of metal to be formed, and displacing simultaneously with the displacement of the part the central slide so as to shape angular volumes of the central portion of the sheet by application of the sheet against the surfaces of the central part of the support.
Patent ZA-856712-B (ZA)
Title: Viability test device
Inventor: HEMMES PAUL
IPC: C12Q1/00
Filed: 1985-09-02
Abstract: A viability test device wherein the viability of a test composition for the determination of an analyte of interest can be determined by simply wetting the device with ordinary water. The viability device can be prepared in three formats: a control or calibrator device, an internal control device and a self indicating device. Unreacted analyte, or an analog thereof, can be incorporated in a limited defined portion of a dried carrier matrix incorporated with a test composition to provide an internal control test device. When wetted with water, a positive optical response, usually color, indicates the test composition can provide a viable test for the analyte. The internal control test device is particularly advantageously used by diabetics in their own homes where a negative test response could be due to the desired control of the user's condition or due to deterioration of a test composition because of unfavourable storage conditions.

The air is exhausted, and the liquid in question comes to occupy the space included between the module (1) and the walls of the case. A small quantity of air contained under the diaphragm (19) expands under the effect of the negative pressure and causes this diaphragm to swell, which gives a compensating volume allowing thereafter the thermal expansion of the liquid within the case and without subjecting the walls of the latter to stresses.

Title: Method for textile product against of searching in luminous and infrared range and the textile product
Inventor: DR GERI ISTVAN
IPC: D06P3/87
Filed: 1995-11-02
Abstract: A terrain-coloured textile fabric for protection against military reconnaissance has properties effectively camouflaging against recognition in the visible and infrared electromagnetic spectrum range. It has, in particular, a printed-on camouflage patterning which consists of colour spots and which is applied to a textile material, if appropriate after a precolouring of a natural-coloured textile material has been carried out. The reflection (reflectance) of the colour spots of the camouflage patterning is in each case within prescribed percentage values in precisely defined spectrum ranges for the differently coloured spots of the textile material. By the method according to the invention, the colours of the colour spots forming the camouflage patterning are in each case selected as a function of the emission spectrum of the surroundings of the object to be camouflaged from a combination of colours in which the reflection (reflectance) of the individual colour spots of the camouflage patterning is within the prescribed percentage ranges.
