The updating of candidatures commences with creation by the employing organisation of a computer file of selected candidates for preliminary consideration, with the surname and first name of candidates recorded in the file. A confidential code is then automatically attributed to each of the candidates, and the code is communicated to the applicant by post. The communication invites the candidate ...

The present invention relates to a bearing particularly for a floating spindle. Such a bearing includes several substantially straight supports (6, 7, 11), one of which, at least (11), can move in a substantially radial direction in proximity with the spindle held (1). Preferably, the supports circumscribe a circle of diameter slightly greater than that of the said spindle.

A polyolefin coating is produced on a substrate by (a) contacting the substrate with a liq. compsn. contg. a catalyst for olefin polymerisation, (b) sepg. the substrate and the compsn., and (c) polymerising an olefin in the gas phase in presence of the substrate. Also claimed are: (i) a component comprising a substrate and a coating obtd. by the above process; and (ii) the use of a component compr...

The appts. for determining specific characteristics of the skin includes an optical fibre (12) carrying light from a source (15) such as a xenon lamp combined with a monochromator to the skin surface. Two further optical fibres (13, 14) carrying light to a measuring device (16) which may comprise two photomultipliers linked to multi-channel digital voltmeter. The two output optical fibres receive ...

Such a high-voltage transformer has a multiplicity of part-windings (7) located in chambers (4) and diodes (3) located inbetween. It is the object to allow a multiplicity of diodes to be accommodated without the total space requirement for the transformer being significantly increased. Several diodes (3) distributed over the circumference are in each case arranged without mutual offset in the axia...

A device including means (13-16) for generating an alternating magnetic detection field in a detection space in order to repeatedly saturate and desaturate one or more targets (12), and means (17-21) for sensing the resulting harmonic disturbance of the alternating magnetic field. The device further includes means (22, 23, 24) for generating an essentially continuous magnetic inhibition field on t...

A method for the dynamic reconfiguration of a signal frame structure, wherein each frame is structured in at least one subchannel having a number, order and/or format capable of being altered under the control of a reallocation command, time interleaving on N frames being selectively performed for each subchannel. According to the method, in the transient state, and for the N frames following a re...

This invention deals with an improved adhesive additive, adhesion compositions, articles, and structures manufactured utilizing such adhesive compositions. More specifically, this invention deals with an adhesive additive which is a combination of cement, water, calcium chloride and a curable polymeric latex which when used to bond cementitous substrates, gives bonds with enhanced tensile strength...
