Abstract: In an adiabatic heat exchanger,    using the principle of kinetic cooling, a carrier gas is forced through a number of  narrow,  heat-conducting  pipes  wherein  its  velocity increases  and  its  temperature  drops.    Incoming  gas  is forced  to  pass  over  these  now  cold  pipes  causing precipitation of a portion of the gas and an increase in temperature of the remaining portion.   Such an arrangement permits  for example removal  of   a condensible gas e.g. water vapour from a non-condensible carrier gas without the necessity of using an additional cooling medium.

Abstract: 1310932 Windows W FRACH 20 Feb 1970 [20 Feb 1969] 5723/70 Heading E1J [Also in Division F2] A control device for hydraulically sealing or holding a window by pressure hoses 1, 2, 3 comprises two rotatably mounted pinion wheels cooperating with two displaceably mounted gear racks 9, 10 connected to moveable parts of two piston and cylinder arrangements 11, 12. In Fig. 2, shaft 19 is rotated in a clockwise direction to move rack 10 out of engagement with pinion wheel 4 by pressure of cam disk 13 on stop 17 and to move rack 9 into engagement with another pinion wheel behind wheel 4. Piston 12 is drawn towards the pinion wheels by rack 9, producing suction at the cylinder bore to empty hoses 3 and 1 (Fig. 1) which are connected by bores 7 and 8 into the cylinder bore. The window is thus unsealed on all sides except the lower horizontal and is free to tilt about horizontal axis 30. Anticlockwise rotation of the shaft from this position reverses the process to reseal the window until the position shown in Fig. 2 is reached. Continued anticlockwise rotation then releases pressure in hoses 2 and 3 to unseal the window and allow it to pivot about vertical axis 29.

Abstract: A novel family of crystalline, microporous aluminophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures of aluminophosphate gels containing a molecular structure-forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with uniform pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.

Patent NO-180700-C (NO)
Inventor: GRIFFIOEN WILLEM
IPC: G02B6/44
Filed: 1991-02-26
Abstract: The invention comprises an improved method for installing a cable (4) in a tubular cable conduit (6) with the aid of the drag forces of a flowing medium and a pulling plug which can be used in this method. Coupled to the foremost end (8) of the cable in the conduit is a partially leaky pulling plug (10) which is provided with a flow opening (12) for the flowing medium. Said flow opening (12) is so dimensioned that, on the one hand, no harm is done to the drag forces of the flowing medium along the cable (4) but, on the other hand, a small pressure difference is maintained across the pulling plug, with the result that the pulling plug (10) energised in this way exerts additional tensile forces on the foremost end (8) of the cable (4) which compensate at least at that point for compressive forces arising as a consequence of intrinsic curvatures. Said flow opening is preferably such that during the installation of a cable the flow velocity in the flow opening (12) is essentially equal to that of sound in the flowing medium (shock wave condition). The flow opening (12) can be chosen as constant, but may also be regulated in a pressure-dependent manner to maintain the said shock wave condition better. Three embodiments of such a partially leaky pulling plug (10) are described, namely one having a constant flow opening, one in which the size of the flow opening varies with an essentially constant pressure difference across the pulling plug and one in which the size of the flow opening varies with the pressure at the position of the pulling plug. The pulling plug preferably has a circumferential suction seal with the inside wall (11) of the conduit (6). Advantages are reduction of the risk of upsetting and buckling, generally greater installation lengths in one stroke, and a lower compressor power. <IMAGE>

Abstract: A recording and/or reproducing apparatus for recording and/or reproducing information signals with the use of a tape cassette is provided with a pair of reel shafts, each having an engaging member mounted with a bias towards the end of the supporting shaft, and a tape cassette transfer mechanism adapted for shifting the tape cassette inserted by way of the cassette inserting opening in a first direction normal to the reel shafts and guiding or loading the tape cassette for inserting and engaging the reel shafts with a pair of tape reels within the tape cassette.          When at least the tape cassette transfer mechanism is set at a position facing the cassette inserting opening, the tape cassette is moved by the tape cassette transfer mechanism towards the proximal side of reel shafts, to reduce the displacement in the second direction of the tape reel of the tape cassette by the tape cassette transfer mechanism to a value lesser than the thickness of the tape cassette to reduce the thickness of the apparatus.          After completion of the tape cassette loading by the tape cassette transfer mechanism, the tape cassette is partially exposed to the cassette inserting opening to prevent a second tape cassette from being introduced into the cassette inserting opening after completion of loading of the first-mentioned cassette.

Title: Die cut disposable grounding wrist strap
Inventor: KLEPEL DONALD EARL
IPC: H05F3/02
Filed: 1990-09-05
Granted: 2000-06-20
Abstract: An inexpensive grounding wrist strap and tether for draining excess electrostatic charge, which may be used once and then disposed. The strap and tether are formed integrally and include a conductive strip having a discrete resistance portion for safety considerations.      The discrete resistance portion is formed by making a zig-zag pattern of cuts in the conductive strip, thereby increasing the length of the current path through the discrete resistance portion. Due to the slight resistivity of the conductive strip, the lengthened current path results in a discrete resistance being built into the strip. The cuts may be made in the strip at the same time the strip is fashioned out of a sheet of the conductive material, such as carbon loaded polyethylene.
