Abstract: ABSTRACT Coil material such as reels of steel become telescoped when they are shipped or handled and a very difficult problem is presented to move them back to the original desired condition.  Also, it is necessary to rewind coils of steel reels so that they are tightly wound.  The present invention provides means for changing the telescoped condition back to the original reeled condition and also for rewinding the reel so that it is tight in a simple and inexpensive manner.

Abstract: Abstract of the Disclosure A snap-action thermal relay in which a thin sheet of spring material having a central opening is mounted at one point along one edge and is crimped along an adjacent edge to distort the sheet into a slightly convex bowed shape.  A heater element in the form of a thin band of metal is anchored at either end to the normally convex surface of the sheet adjacent opposite edges of the sheet, with a bridging member inserted between the band and the sheet to put the band under tension.  A printed circuit heating element is applied to the band on the side opposite from the sheet.  The tension in the band holds the sheet in a concave bowed condition.  Heating of the bank reduces the tension in the band and allows the sheet to snap back to its normal convex bowed condition.  This action brings the band into direct thermal contact with the convex surface of the sheet over a substantial length of the band to provide good conductive transfer of heat from the hand and heater to the spring sheet.

Abstract: ABSTRACT           A hose clamp body is provided for use with a pair of bolts each having a shank and a head.  A surface on the body grips the hose and a first opening generally transverse to a first surface on the body receives the shank of one of the bolts.  The head of this one of the bolts is provided with a flat side surface laterally spaced a predetermined distance from the diametrically opposite side of the shank.          Provided on the body is a second surface which intersects the first surface and extends away therefrom to an upper edge to form an acute angle relative to the longitudinal axis of the opening.  The predetermined distance is less than the transverse distance between the upper edge and the diamet-rically opposite side of the first opening and greater than the transverse distance between the intersection and the diametrically opposite side of the first opening so that the flat side of the head of the above-mentioned one of the bolts engages the body second surface before this bolt head contacts the first surface to prevent this bolt from turning relative to the body.  The body also has a second opening on the other side of the gripping surface to receive the other of the bolts, the body having a third surface generally transverse of this second opening and a fourth surface intersecting the third surface and extending therefrom, and this fourth surface being slanted at an angle of greater than 45° relative to the longitudinal axis of the second opening.

Abstract: ABSTRACT OF THE DISCLOSURE             A novel polyester is provided which has been found to exhibit an anisotropic melt phase at a temperature which enables it readily to undergo melt processing  to form quality fibers, molded articles, etc.  The polyester of the present invention is different in character than polyesters of the prior art and includes as essential ingredients moieties derived from para-hydroxy benzoic acid, 1,2-bis(para-carboxy phenoxy)ethane, terephthalic acid, and substituted hydroqui-none in the proportions indicated.  The polyester of the present invention generally can be more enconomically produced than polyesters of the latter three moiesties (two of which are relatively expensive) while surprisingly yielding an aniso-tropic melt of relatively low viscosity at a desirable tem-perature for melt processing in spite of the substantial concentration of relatively stiff para-oxbenzoyl moieties which contribute to the overall nature of the resulting polyester. In a preferred embodiment the polyester is capable of under-going melt processing at a temperature below approximately 300°C., and in a particularly preferred embodiment at a temperature below approximately 290°C. (e.g., with standard equipment commonly used to melt process polyethylene terephthalate).

Abstract: ABSTRACT     This invention relates to a movable load carrying device for vehicles with cargo space. Such load carrying devices render possible loading and unloading operations from three sides and with suitable working positions of the operator, but on the other hand it was found, that the inward as well as the outward movement of known load carrying devices into and, respectively, out of the cargo space of a vehicle are troublesome and require; relatively great exertion and often even heavy lifting, which to some extent takes away the ad-vantages with respect to loading and unloading. In order to eliminate these and other disadvantages, according to the present invention a movable load carrying device is proposed the load table (4) of which is formed on its lower surface with guide grooves (8) for a pair of carrying rollers (9), which are mounted in the rear portion of the cargo space and capable together with the wheels (14) of the support legs to movably support the load table (4) as long as the centre of gravity of the load table is located outside the carrying rollers (9), and together with rollers (13) provided at the forward portion of the load table, seen in the inward movement direction, to movably support the load table as long as the centre of gravity of the table is located inside the carrying rollers (9).

Abstract: ABSTRACT OF THE DISCLOSURE           A cassette for measuring the torque output of the tape drive of a cassette recorder and/or player has a housing with two hubs, to which the ends of a tape are connected.  A slide is dis-placeable against the force of a spring and carries a tape-deflect-ing roller about which the tape is trained.  The slide carries several pointers for movement with it.  Several different exposed faces of the cassette housing have respective dials provided on or at them, and each pointer cooperates with one of these dials. Pull applied to the tape as a result of hub rotation by the tape drive of a machine being tested, causes the slide to be displaced from its rest position.  The degree of this displacement is a function of the applied torque which can be read off all of the several dials.          At least one of the dials will always be exposed for observation, irrespective of what particular type of cassette machine is being tested.  Various modifications are also described herein.

Abstract: ADJUSTABLE SURGE AND CAPACITY CONTROL SYSTEM          Abstract:      An adjustable surge and capacity control system for matching a capacity control system to an inverter-driven centrifugal compressor based liquid chiller having unknown surge characteristics.  The necessary adaptation of the capacity control circuit to a particular chiller is attained by the provision of two potentiometers (104,120) which are adjustable to develop a functional which avoids surge and operates the system in an efficient manner at all feasible operating point loads and heads.  The use of a circuit employing a pair of potentiometers permits the formation of the appropriate functional with two degrees of shaping flexibility.
