Patent SE-8106731-L (SE)
Inventor: WATES M J
IPC: F04C29/02
Filed: 1981-11-12
Abstract: A rotary compressor with forced displacement compresses a mixture of a gas and a cooling liquid which is intended to absorb heat generated by the compression working cycle. A cooling unit comprises separate heat exchangers for cooling of the compressed gas and the cooling liquid and a centrifugal fan which draws the cooling air through the heat exchangers. Due to the fact that the cooling air is drawn in through the heat exchangers a uniform air flow is achieved so that the heat exchangers can function with a high degree of efficiency and the centrifugal fan generates a pressure which is sufficient to deliver the heated cooling air to a point remote from the compressor. This release of the dissipated heat at a remote point increases the efficiency of the compressor because this prevents heated cooling air from mixing with the air drawn into the compressor. In addition it increases the efficiency of the heat exchangers. The waste heat can be recovered by leading it to a point where the heated cooling air can be used for room heating or process heating purposes.

Abstract: A vehicle wheel trim member, which may be a hub cap (18) or wheel cover, has a spring steel ring (36) on the inboard face thereof adapted to engage the wheel mounting nuts (20) or studs to releasably retain the trim member on the wheel, the ring being mounted on the trim member by means of portions of the ring radially movably located in slots (34) in the trim member such that the retention forces generated by the flexed ring are absorbed by the studs, and the trim member having circumferentially spaced abutments to engage the studs or nuts to prevent relative rotation between the trim member and wheel. As illustrated the trim member has tubular projections (28) which fit over the nuts to limit relative rotation, and the ring (36) passes though slots (34) in the inside face of the projections (28) to engage grooves (40) in the nuts. Alternatively the ring may engage the nuts from the radially outer side. The ends of the ring (36) may be fixed together or connected by means of a tensioning cam mechanism. <IMAGE>

Abstract: A borehole reservoir includes a plurality of vertical boreholes (5, 6) in each of which there is arranged pipes (9, 17) for feeding water to and returning water from the boreholes. In order to avoid sealing the boreholes (5, 6) so as to prevent leakage when the water-circulating circuit is placed under pressure, all connections between the boreholes have, in accordance with the invention, been placed at a level beneath the ground-water level (2). This is achieved by providing spoke-like, horizontal boreholes (3, 4) from the central shaft (1), these boreholes intersecting the vertical boreholes (5, 6) located along the spokes and serving as supply and return lines for the water to and from the vertical boreholes. Since the pressure of the water within the boreholes is the same as that of the water externally of the boreholes, there will be no leakage from the boreholes (5, 6).

Abstract: A rain water roof outlet for a building for conducting rain water from a roof as an airless flow, i.e. as a full water flow. The arrangement includes a vertical pipe which at its upper end is connected to a wider trough mounted at the level of the roof. In the trough, above the mouth of the vertical pipe, is mounted a lid, which by special formation of its shape or by means of additional elements is adapted to increase the friction against the water flowing towards the mouth of the vertical pipe. This friction counteracts the tendency of creating whirls in the water stream and thereby contributes to producing full water flow in the vertical pipe by preventing air entry. The lid is preferably a net.

Abstract: The invention relates to an apparatus for obtaining an enlarged image of a part of the field of view of an IR camera. A device (4,6) for horizontal deflection and a device (5,17) for vertical deflection deflect IR rays (7) incident on the camera towards detector elements (8). These sense the field of view along parallel scanning lines costituting bands, and generate video signals so that the lines can be presented on a display screen (3). In accordance with the invention the device (5,17) for vertical deflection forms a smaller portion in height of the field of view than normal height thereof. The bands partially overlap each other so that the scanning lines in one band fall in the space between scanning lines in a preceding band. The bands are individually noted in the reading order in separate memory (C, D, E). The data for the lines falling in the space will be noted at addresses which do not correspond to their true position in the field of view. This is corrected by a readout device (31,32) which adjusts the readout to the image screen (3) such that the readout alternates between respective memory parts in the sequential order of the image lines.

Abstract: The thin material (1) is formed into a roll (2) and apart from a pulse transmitter (5) coupled to a driving support roller (3), a unit (6) processes the transmitted pulses, where a specific number of pulses corresponds to a determined strip length (1a). A further pulse transmitter (13) is fitted on the roll axis to measure the number of revolutions (n) through which the roll has rotated with a further calculating unit used for multiplication, division and addition. For a specific number of winding revolutions, the rolled material length is measured, and a corresp. average dia. is calculated. Measurement is repeated continuously, so that at the next measurement sequence the same number of winding revolutions is used and a new rolled material length is measured, the resultant new average dia. being calculated. The difference between the average diameters is continuously formed, and the actual outer dia. of the roll and the material thickness are calculated. The remaining material length to bring the roll to the requisite external dia. is then calculated. (Provisional basic advised week 86/40)

Abstract: A fold-up chair solves the problem of the "wandering clothes" effect and a gentle downward movement by means of the fact that its backrest 1, when folded back to a rest position (broken line), is displaced with its lower edge in under the seat 2. This is achieved by the fact that the backrest 1 is coupled by means of an arm 16 to an eccentric disc 5 whose centre is mounted in the chair stand 3, and by the fact that a link arm 4 is connected rotatably to the backrest and the stand. One end of the link arm 4 is mounted at a point c at a distance from the lower edge of the backrest above the attachment for the arm 16. The other end of the link arm is rotatably mounted on a pivot d which is supported by the stand 3. The seat 2 can advantageously be mounted on the same pivot d, but it can also have a separate pivot 7. The gentle drop movement is achieved by the fact that a gas spring 6 known per se is supplemented by a helical spring 10 whose length is shorter than the stroke of the gas spring. By means of a displaceably mounted yoke 11, the position of activation of the helical spring can be changed to adapt to persons of different weight. <IMAGE>
