Abstract: The process for the production of a decorative glass article involves feeding a heat-softened glass material to a mould (5), the decorative effect of the glass article being achieved, at least in part, by means of coloured sections. The surface of the mould (5) which is to come into contact with the glass material is coated, at least partly (at 13 and 14), with a dye before the glass material is fed in. After the glass material has been fed in, it is pressed against the mould (5) by means of a suitable instrument (8) in order to form a blank (15) with the desired shape from the glass material. After slight cooling, this blank is separated from the mould (5). At least the coloured parts of the surface of the blank (15) are subjected to heat treatment, the temperature being significantly higher than the temperature at which the blank (15) was moulded. <IMAGE>

Abstract: In an optical scanning device in which the active scanning means comprises a rotating polygon provided with a plurality of reflecting facets, the so-called optical invariant   <IMAGE>   wherein  phi  is the aperture of the scanning device,  alpha  is the field angle of the scan, the NETD is the so-called Noise Equivalent Difference Temperature, is increased by passing the beam path against the polygon so as to be reflected therefrom a multiple of times, and therein with substantially complete tracking of the facets while substantially filling the same completely over the full extension of the facets, with the exception of that facet located nearest the beam detector. This is effected with the aid of stationary beam-deflecting optical means which cause the mutual reproductions between facets with reflection of substantially full extension in the rotary direction of the polygon to take place against diametrically opposed facets at a magnification of approximately -1.

Abstract: An air current is produced and conducted through the strip (18) with its flow speed measured. The pressure drop over the strip is also measured, and from these measured values a formula is used to calculate the air flow speed at a selected pressure drop, thus to determine the material permeability. In the formula, the air current flowing speed at a specific reference pressure drop over the material strip equals the measured speed multiplied by the quotient of the reference pressure drop divided by the measured pressure drop to the power of a typical constant for the strip. - The equipment used comprises a component to produce an air flow through the material, an air flow meter (14), a movable measurement head (15) which conducts air flow through the strip (18) and which is connected to a pressure gauge. The gauge measures the pressure of the air flow, and an electronic unit, starting from the measured values of air flow speed and pressure drop, calculates a reference value for the strip permeability.

Abstract: Power plant comprising a bed vessel housing a fluidizable bed (14) of particulate material and comprising a cleaning plant for separating solid particles from the combustion gases leaving the bed vessel. A gas outlet from the bed vessel (11) is formed as a centrifugal separator (20) intended to primarily separate coarse material containing unburnt fuel leaving the bed (11) together with the combustion gases. Suitably the separator (20) extends into the bed vessel (11), and separated material is returned to the bed (14) through a return conduit (34), which is preferably located close to the bed vessel wall. This conduit (34) opens into the bed vessel (11), near the bottom (12) thereof. For the return transport an ejector (35) may be used to overcome the pressure difference existing between the separator (20) and the orifice of the conveying conduit (34). The propellant gas may consist of combustion air from the space (16). If the pressure difference between the space (16) and the orifice of the return tube (34) is insufficient to obtain the necessary driving power, a booster compressor (36) may be used to increase the pressure of the propellant gas.

Abstract: A brushless AC motor, which has a rotor (17) and a stator (18), drives two oil pumps (20,21) one of which (20) drains the engine oil sump, whilst the other (21) feeds lubricant to the requisite points. The feed pump (21) sucks oil from the bottom of a storage tank (23) through an inlet (26) and feeds it under pressure through conduits and channels (27,28,29) to the engine (10). Lubricant then finds its way back to a collection area (11) in the form of a sump, from which it is pumped back to a space (35) between a filter (24) and the wall of the storage tank (23). The drain pump has a higher capacity than that for feed to obviate accumulation of lubricant in the sump. - The two pumps are driven by a three-phase brushless AC motor fed with variable voltage at variable frequency from an inverter comprising six transistor switches (51-56), and driven from the vehicle battery (45). A delay circuit (47) is arranged parallel to the ignition switch to operate the pumps at a predetermined time after the ignition switch is opened. The system has a coil (48) and a capacitor (49), forming together a low pass filter to damp transients. Pressure in the feed conduit (29) for lubricant is monitored by a pressure current switch (41) and a pressure converter (42).
