Solar collectors using the photovoltaic system are in widespread use. A more simple alternative is to obtain hot water using a black-coated absorber. Hitherto, known constructions were unsuitable for use in the damp air of islands or coastal regions because, in such cases, the solar radiation is disrupted by the formation of condensed water. The object of the invention is to provide a solar collec...

PURPOSE:To reduce pressing down force of an inching pedal by providing a pressure chamber pressing a plunger between a step of the outer periphery of the plunger and a valve body, and communicating this pressure chamber with a pressure chamber pressing a spool forward. CONSTITUTION:Under the release conditions of an inching pedal 5, a plunger 2 is pushed rightward by a return spring 7 while a spoo...

In an electromagnetic operating mechanism for a gas exchange valve of an internal combustion engine wherein two control magnets are arranged in spaced relationship above the valve and an armature is axially movably disposed between the control magnets and and actuator rod extends from the armature through one of the control magnets to engage the valve, two compression springs are arranged outside ...

Yarn 21 is passed over a yarn guide 17 spaced from a bobbin 20 and through a passageway (14) through the interior of the bobbin holder.

The mechanism secures a curved flexible item (10) on the cylinder (2) of the printing press. It has a spindle turning in a groove in the cylinder parallel to the axis of the cylinder. The spindle is in several sections (14.2), each with teeth (17) at the periphery and by which it meshes with a spring-loaded (24) transverse rack (19). The latter is slid in opposition to the spring by an actuator (4...

The invention relates to a method and system for controlling the functions of a mammography apparatus, in which control method the mammography apparatus is used to make radiographic exposures in different projections from breasts (M) to be examined. The method uses a control system (10) having a memory (16) into which, prior to the exposure, projection parameter information is stored. On the basis...

An improved x-ray image sensor system and method enables the use of an uncooled or only slightly cooled CCD array (18a) within a standard size x-ray film cassette (10). The sensor system enables the provision of a number of advanced functions such as remote diagnostic capability, variable image resolution, real-time exposure control, automatic x-ray detection, a low-power "sleep" mode, and automat...

The apparatus is for holding the stator of the rotatating vessel of a centrifuge in a way allowing for an easy and rapid handling. It includes: a pivotable swing arm (50) having a first end (52) and a second end (54), the second end (54) having an engagement portion (56) configured to engage the stator of the rotating vessel; a shaft (70) connected to the first end (52) of the swing arm (50) for s...

For controlling the compression output power of an exhaust turbocharger, irrespective of the charge pressure produced by the compressor of the turbocharger, a separate control pressure source for an adjusting device (5) of a valve (7) in a bypass line (8) to the turbine (10) of the exhaust turbocharger is provided in the form of a compressed air pump (1) which, controlled by a control device, supp...

Microporous battery separators made of polyolefins and fillers, for lead/sulphuric acid accumulators, are characterized by the fact that the polyolefin component has an average molecular weight of over 5,000,000, and that the content of extractable oil in the finished separator is less than 1 %.

The invention relates to a method of manufacturing a replication master tooling article suitable for manufacturing replicated articles by machining a substrate surface with laser energy to produce a plurality of geometric structures in the substrate, the geometric structures having side surfaces extending from the surface of the substrate into the substrate.

A torque distribution control system for a four-wheel drive vehicle has an engine output controller (22) which controls the output of the engine of the vehicle, a braking controller (25) which separately controls the braking forces applied to the left wheels and the right wheels and/or the braking forces applied to the front wheels and the rear wheels. A torque distribution changing system (26) de...

The invention relates to films of linear polyester containing glass spheres having a certain particle size distribution and in a certain amount. The addition of the glass spheres improves, inter alia, the dynamic coefficient of friction of the film. Preferably, a second film additive, fumed silica, of a controlled particle size distribution and weight is added to the film. The addition of the fume...

Because of inherent delay in magnetic flux propagation in the magnetic circuit, the transient opening magnetic force on the armature does not build as rapidly as the injector driver circuit may be capable of commanding. This transient force is augmented without increasing the package size of the magnetic circuit. A fuel injector has a novel solenoid actuator magnetic circuit that has slots, convol...
