Detection of the presence of an animal body, for instance a human, in a detection zone is achieved by generating a low power LF field (17) between antennae (12, 18), and by measuring the disturbance of this field by the body. An analyser (16) is used detect such disturbance by measuring changes in the phase of the received signal (19).

Coated solid bodies comprising a core of an active composition and having a water-soluble or dispersible micro-porous or net-coating. The coating improves the mechanical characteristics of the solid body and allows for good dissolution. The coated solid bodies preferably take the form of detergent tablets.

Shaped bodies, containing at least one shaped body with an unstressed three-dimensional inherent volume form that has at least one integrated curved part and can be displaced and/or partially or wholly transformed into another three-dimensional volume form by means of an active element connected to the shaped body, using a variable force of pressure/tensile force.

A method of manufacturing a body having channels extending through it and a body so formed. The method comprises the steps of working a single strip of material to provide corrugations the crests and valleys of which extend in a direction across the strip. The strip is then folded about an axis which lies at an angle to the crests of the corrugations in order to form layers each having the crests of the corrugations angled to, and lying across the crests of the corrugations of an adjacent layer ...

This invention relates generally to a novel method of manufacturing a composite body and to novel products made thereby. More particularly, the invention relates to a method of producing a self-supporting composite body comprising one or more boron-containing compounds, e.g., a boride or a boride and carbide, by reactive infiltration of molten parent metal into a bed or mass containing boron carbide, and, optionally, one or more inert fillers and permitting residual or excess parent metal to rem...

The present invention relates to the formation of a macrocomposite body by spontaneously infiltrating a permeable mass of filler material or a preform with molten matrix metal and bonding the spontaneously infiltrated material to at least one second material such as a ceramic or ceramic containing body and/or a metal or metal containing body. Particularly, an infiltration enhancer and/or infiltration enhancer precursor and/or infiltrating atmosphere are in communication with a filler material or...

The disclosure relates to a tube coupling body (13) of circular external cross-section having an internal throughway open at one end to receive a tube with a collet form tube locking device in the open end of the throughway to lock a tube in the coupling body. The coupling body has on its outer side an encircling groove spaced from said one end of the body and a grab ring mounted in the groove of V-shaped cross-section facing the axial direction of the ring towards said one end of the coupling b...

A method of shaping a body, suitable for use in the building or furnishing industry, including: engaging a surface region of the body with a tool having a predetermined profile; effecting relative movement between the body and the tool in a direction generally parallel with a surface of said region, the body being formed of a material which is sufficiently friable as it is engaged by the tool during the relative movement to be removed but sufficiently rigid for adjacent material to remain attach...

A vehicle body has a door aperture the door aperture being bounded along its lower edge by a sill section and by forward and rearward upstanding post sections, a door being located in the door aperture, the door being hinged to one post section and releasably engaging a catch on the other post section, a tie bar is provided adjacent the edge of the door remote from the sill section, clamping elements being provided for releasably clamping the tie bar with respect to both the forward and rearward...
