A fuel tank stores fuel gas. A catalytic burning section is connected to the fuel tank for generating heat based on an oxidative reaction between the fuel supplied from the fuel tank and air. The fuel tank and the catalytic burning section are assembled as a catalytic heat generating apparatus. The catalytic heat generating apparatus is detachably installed in a housing of a heater section. The heater section has both ends provided with a pair of belt portions wound around a user's body.

The invention relates to a brush suitable for taking a smear from the endocervical canal, comprising an elongated handle and a brush head placed on the handle, which brush head comprises a mandrel lying in line with the handle and brush hairs which run substantially parallel placed on the mandrel.

This wire stock is made of a microalloyed steel having a carbon content of between 0.2% and 0.6% by weight and furthermore containing at least one alloying element selected from the group consisting of vanadium, molybdenum and chromium, in a proportion, by weight, of at least 0.05% and at most 0.5% of said alloying element or of the combination of said alloying elements. Such wire stocks are manufactured in order to produce, by deformation and heat treatment, a ready-to-use wire which is used, f...

A powder toner composition includes a particulate synthetic thermoplastic material, refractory metal oxides, and a powder lubricant. The particulate synthetic thermoplastic material is surface coated with a blend of the refractory metal oxides and the powder lubricant. At least one of the refractory metal oxides is surface-treated. The powder compositions exhibit fluid properties when subjected to mechanical agitation or aeration, and settle as compacted solids when agitation/aeration ceases. Th...

A ventilator includes a gas flow generator for generating a gas with an adjustable pressure and/or flow rate, an inspiratory line with a proximal end, connected to the gas flow generator and a distal end, devised for connection to a patient, an expiratory valve connected to the inspiratory line at a specific distance from the distal end of the inspiratory line to evacuate gas exhaled by the patient, a pressure gauge and/or a flow meter arranged to measure pressure and/or the rate of gas flow in ...

A trigger arrangement suitable for use in oscilloscopes which include a cathode-ray tube as a change display device, a trigger output signal (10) is displayed from a trigger input signal (6) after the trigger arrangement is released by a release signal (8). Use is made of a series-combination of three bistable elements (2,4,16). The trigger input signal is applied in parallel to the bistable elements and the trigger output signal is obtained after the output of each bistable element has successi...
