Abstract: A method of removing and reclaiming a double metal cyanide (DMC) catalyst from a polyol is disclosed. A polymeric acid that is soluble in the polyol is introduced into the polyol during or after the polymerization reaction. The polymeric acid reacts with the double metal cyanide catalyst thereby causing the double metal cyanide catalyst and the polymeric acid to form an agglomeration in the polyol. The agglomeration is easily separated from the polyol via filtration, for example. The recovered agglomerated DMC catalyst can then be reconstituted using an acid solution.

Abstract: Disclosed are improved handles (200) applicable to a wide variety of apparatuses, equipment and devices found in industry, commerce, in the home, or for exercise or recreational purposes. The improved handle (200) may be fashioned integrally with the apparatus or as a retrofit attachment therefor. In using the handle (200), the person's hand is inserted through an opening (204) and into a chamber (203) formed between the inner and outer walls (201,202) of the handle (200). The palm of the person's hand substantially rests on the convex inner surface (206) of an inner wall (201) of the handle (200), while the back of the person's hand substantially confronts the concave inner surface (207) of the outer wall (202). With this arrangement, the user's hand is maintained substantially in a curved natural "at rest" position, rather than being tightly closed, so that a forceful grip is no longer necessary. As a result, the human effort and energy required to manipulate or control the associated apparatus, equipment or device is substantially reduced, thereby substantially reducing the fatigue normally associated therewith. Moreover, in certain applications (such as portable power tools (246)) the handles (200) provide an enhanced safety feature.

Abstract: For cleaning at least one of the sides of the essentially vertical heat-transmitting walls (4) between two fluids in a heat exchanger (1), solid particles are introduced into a stream (14) of fluid, which particles are smaller than the distance between opposite walls defining the flow of fluid, said fluid with particles being introduced (by 16) into part of a collection or distribution space (11) above said walls (4) and said particles being collected below said vertical walls and discharged from the heat exchanger. The particles are so heavy that they move downwards in the fluid even if this has an upward direction of flow between the walls. The particles are introduced above only part of the transverse plane above the vertical walls (4) and switch means (15) allow switching of said introduction to other parts of said transverse plane periodically. Thereby, the normal operation of the heat exchanger can continue with hardly any pressure loss during cleaning. <IMAGE>

Abstract: A dual-chamber AV sequential pacemaker with the capability of automatically adjusting right heart AV interval to optimize left heart AV interval by compensating for pacing-induced inter-atrial and inter-ventricular conduction delays. Depending on the pacing and sensing action, as determined by the patient's native rate, the predetermined threshold rate and intrinsic AV interval, the pacemaker selects the AV interval. Right heart AV interval is adjusted to compensate for the heart's inter-atrial and inter-ventricular delays. Threshold values are previously estimated, using mean values measured using non-invasive techniques. The pacemaker has a dual phase operating mechanism consisting of an analysis phase followed by a pacing phase. The P wave rate is sensed and compared to a predetermined base rate. If the sensed P wave rate is above the baseline, atrial depolarizations will be sensed by the pacemaker and small number (default = 4) of consecutive native AV intervals will be averaged. If this average is less than a predetermined threshold value, the system will continue in the demand mode, sensing P and R waves. If the average is greater than said value, then the ventricle is paced for n number of times the analysis phase (default = 100 cycles), each followed by a short AV delay (Default = 50 ms) that is intended to compensate for the delay introduced in the onset of left ventricular depolarization after pacing the right ventricular apex. When P wave rate is below the predetermined rate, atrial pacing will occur. During the initial analysis phase, the pacemaker AV interval may be extended to a higher value, say 250 ms, to allow measurement of the native AV interval. At least four AV intervals will be averaged to compensate for possible Wenckebach phenomenon. If averaged AV is greater than, say 220 ms, sequential pacing with AV of 160 ms will take place for 100 cardiac cycles. If averaged native AV intervals are less than 220 ms, atrial pacing with ventricular sensing will be continued with the AV interval set at 250 ms for the next 100 cycles. At the end of either 100 cycle period, another 4-beat analyzing phase is started. Both pacemaker phases (analysis and pacing) are programmable. The 4/100 cycle sequence allows rapid pacing mode corrections under situations such as intermittent block due to exercise or other causes. <IMAGE>

Abstract: Lead frames for microchips and other integrated circuit dies are produced by a continuous manufacturing method and apparatus in which silver spot plating is done prior to etching away unwanted portions of the lead frame substrate. A flexible substrate of a metal alloy is fed continuously from a reel, then spot plated with silver, coated with a photosensitive material, and exposed to intensive light in an exposure chamber using a photoresist or masking tool of predetermined design. The exposed photosensitive material is developed chemically, etched in acid, and placed in a chemical solution to remove any remaining unwanted material. The strip is then dried, cut to predetermined lengths and boxed for shipment. If necessary, the strip is downset and taped before packaging. In a presently preferred process, the metal alloy substrate is 42 alloy (Fe + Ni), and the selective spot plating is silver 100 to 150 microinches (2.5 to 3.8 mucrons) thick. The silver does not dissolve in the etchants and therefore has to be removed from exposed areas, preferably by "reverse" plating techniques. <IMAGE>
