Abstract: A chemical reactor vessel (10) is provided with a plurality of tubes (14) filled with a heat exchange fluid. The tubes (14) are disposed in a heat exchange relationship to the reactor (10) contents and are coupled via rupture discs (18) and a header (20) to a reservoir (22). Upon overheating of the reactor contents, excess heat is ab­sorbed by the heat exchange fluid which boils off to the reservoir thereby maintaining the reactor contents at a preselected safe temperature.

Abstract: An air flow system in a sealed data recording disk file directs selected portions of the air flow from the periphery of the stack of rotating disks to specific heat generating components in the disk file. A converging duct (82) is attached to the disk file housing (12) and has its inlet (86) located in close proximity to the periphery of the rotating disks. The outlet (89) of the converging duct is located adjacent to the coil (56) of the voice coil motor (VCM) actuator and oriented such that the flow exiting the outlet is perpendicular to the linear path (58) of the VCM. The outlet of the duct has an area smaller than that of the inlet so that there is an increase in velocity of the exiting air, which increases the cooling rate of the VCM. The shield directs a second portion of the air flow from the periphery of the disks across the electronic read/ write modules (80) located on the arms (54) which support the read/ write heads (50).

Abstract: A polyester resin composition useful in preparing shaped, cured products having good impact strength and surface characteris­tics. The improved impact strength and surface characteristics result from the incorporation of a conjugated diolefin polymer wherein from 70 to 100 mole percent of the conjugated diolefin monomer incorporated therein is incorporated via 1,2-addition. The conjugated diolefin polymer may be a copolymer and is, preferably, a block copolymer containing at least one polymeric block contain­ing predominantly monoalkenyl aromatic hydrocarbon monomer units and at least one polymeric block containing predominantly con­jugated diolefin monomer units. Copolymers useful as modifiers in the polyester resin composition will contain at least about 35 weight percent conjugated diolefin monomer so as to ensure that the copolymer is an elastomer. The polyester resin composition may comprise thermosetting, unsaturated polyesters or thermoplastic saturated polyesters.

Abstract: A digitally operated printer, particularly a laser printer, has a control system which controls supply of operational signals to the printer from a signal source. The control system incorporates a converter (5) which converts groups of input signals into larger groups of operational signals. The operational signals are generated in correspondence with coded information carried by the input signals, e.g. by reference to a store (7) of predetermined operational signals. The larger groups of signals are fed at a faster rate than the input signals, so that the effect is to enhance the grey tones produced by the printer.

Abstract: By means of an operation process acting in the same direction, a sun shade is moved to different height positions without changing its closed position and opened and closed by drive reversal. In the tubular mast (1) a telescopic bar (3) is guided displaceably by means of an adjusting device (11, 12), the top end of which telescopic bar bears a bearing ring (8), on which the closing rods (15) are suspended. Its bottom end is closed by an end face (7), in the nut thread (6) of which a threaded spindle (9), which can be rotated by a crank (11), engages with automatic locking. A bearing ring (17) is guided so as to be adjustable in height on the tubular mast (1) and it can be fixed to the latter by a clutch (5). When the clutch is closed, the distance between the bearing rings (8, 17) is changed by the spindle (9), that is to say the sun shade is opened or closed. Even at the smallest opening angle of the canopy rods (15), the clutch (5) opens automatically. Then the sun shade can be raised and lowered without changing its closed position. Since the closing operation is also controlled automatically, a change cycle in the opening and lifting region can be controlled automatically by raising or lowering the first bearing ring (8), which simplifies the operation and increases the operational reliability. <IMAGE>
