Abstract: A process for producing a foamed polymer, particularly a foamed polyofefin, of highly uniform low density. 
     A mixture of a polymer-forming material, a cross-linking agent, and a blowing agent is placed in a mould and reacted. This reaction product is cooled until the differential temperature between core and surface is below a predetermined maximum, and removed from the mould. 
     The cooled product is then subjected to dielectric heating, preferably by microwave irradiation, to cause uniform heating and highly uniform expansion to produce a foamed polymer of highly uniform low density. 
     The process of the invention enables production of relatively thick foamed polymers with a uniformity of density not possible with conventional foaming processes wherein high differential temperatures lead to non-uniform densities and distortions of the foamed product. The process of the invention also avoids the serious problems with excessive pressures encountered in attempting to produce highly foamed polymers in single-stage processes carried out entirely in closed moulds.

Abstract: Polyether polyols are produced by the oxyalkylation of a polyhydroxy compound by a method in which a salt of the polyhydroxy compound is initially prepared and the by-products of salt formation are substantially completely removed prior to reaction of the salt with an alkylene oxide. For preference, the salt formation reaction is effected by dissolving the polyhydroxy compound in a nitrogen containing heterocyclic solvent (most preferably N-methyl pyrrolidone) and reacting the polyhydroxy compound with an alkali metal alkoxide to form the salt. The by-product alcohol of this reaction is then removed by distillation or evaporation prior to reaction of the salt with the alkylene oxide.

Abstract: A novel timing control method is utilized in conjunction with an imaging lidar system of the type disclosed in U.S. Patent 4,862,257. This novel timing control is employed in applications wherein the lidar system is mounted on an airborne platform. The timing control method of this invention completely eliminates the glint detector with associated signal conditioner used in the system of U.S. Patent 4,862,257, and instead, relies upon a signal derived from the aircraft altimeter to continually provide platform altitude status. Since the entire system is under the control of a computer, the altimeter signal can be interpreted and used to adjust total delay so as to automatically track changing platform altitude. It is now possible to initiate all timing from the occurence of the laser "lamp fire" signal. The total delay to camera "gate on" is now the "lamp-to-laser" delay, plus round trip platform altitude delay (computed from the altimeter signal), plus desired water depth delay, less system delays.

Abstract: Safety circuit for gas or oil burners, having a solenoid valve which passes the fuel flow through and has a tripping and a holding winding and which can be cut in, together with an ignition unit, via a control switch, the pass-through of which is dependent on the burning of a flame detected by a flame-monitoring circuit. Connected in series with the control switch and in front of the solenoid valve is a fusible cut-out having a heating resistor, and located in front of the tripping winding is a monitoring switch which makes the tripping winding dead when there is a burning flame. The control switch receives a control voltage which is branched off from the tripping winding and which, if the flame does not burn, blocks the control switch after a short delay time, the heating resistor being rated in such a way that, in the event of a flow of the current flowing across the holding winding, it cannot cause the fusible cut-out to melt, but, in the event of a current flow across the tripping winding, trips the fusible cut-out by melting after a longer delay time. <IMAGE>

Abstract: A personal computer of this invention has a battery pack mounting section (31R) for detachably receiving battery packs having different current capacities. The personal computer also includes a switch mechanism (70, 304) for detecting whether a battery pack has a high or low capacity. Battery characteristic values consisting of charge and discharge voltage/current characteristics in units of batteries are prestored in a memory in a power control CPU (PC-CPU) (306). The PC-CPU (306) refers to the memory on the basis of capacity data from the switch mechanism and reads out the corresponding battery characteristic data. A power supply circuit (30) performs optimal charge control on the basis of this characteristic data. Two battery packs are prepared. When the PC-CPU (306) detects that the currently used battery pack is in a low-battery state, it selects the other battery pack to supply the operating power to the personal computer. At the same time the PC-CPU (306) performs optimal charge control of the battery in the low-battery state.

Abstract: The invention relates to singly cationic complexes of technetium which, as potential radiopharmaceuticals, preferentially accumulate in myocardial tissue. The intention of the invention is to bind singly positively charged lipophilic technetium complexes which preferentially accumulate in the myocardium and have a low accumulation rate in adjacent organs such as, for example, the liver. The object includes a process for the production of the complexes found. The object is achieved according to the invention with singly positively charged technetium complex compounds which enter the myocardium and have the general formula [TcL<1>nL<2>m]<+> in which the ligand L<1> is a polydentate sulphide or a polydentate ether, and the ligand L<2> is a monodentate, neutral or basic complexing agent which is either a halide or pseudohalide ion or an organic complexing agent. The combination of the polydentate and of the monodentate complexing agent is chosen so that the charge transferred by the total of the donor atoms to the metal is one unit less than the number of charges on the technetium. Concerning the process, the object is achieved by reacting the complexing agent L<1> with the second complexing agent L<2> either simultaneously in a mixture or in a subsequent reaction in acidic, aqueous or aqueous-alcoholic solution at room temperature with a technetium compound and with a reducing agent.

Abstract: Disclosed is an optical disk handling system (24), called an autochanger, having two control systems (150Y, l50Z) to provide the six motions necessary to move optical disk cartridges from storage holding cells to an optical drive. The system uses shaft encoders (62, 72) on two motors (60, 70) of the two control systems, and current or voltage feedback from the motors, for all positioning, and for detecting the location of the mechanisms during, and at the end of, moves. The shaft encoders (62, 72) are used to position a mechanism close to the eventual move location, then motor current or voltage feedback is used to determine the opposition to the movement of the mechanism, which tells the control system whether the mechanism has reached its destination. A human operator can enter a cartridge into the system through a mailslot (41), which is rotatable to properly receive or eject cartridges. The control systems use a flip assembly (49) in the autochanger to turn the cartridge over, allowing either side of the disk to be arranged for reading or writing by the optical drive. The control systems use a lateral displacement assembly (51) to move a cartridge from a cell in one of the two columns of the autochanger to a cell in the other column, or to move a cartridge between the optical drive, which is located in one of the columns, to a cell in the other column. The control systems use a cartridge engaging assembly (45) to attach to an exposed end portion of a cartridge positioned in a cell or the optical drive. A longitudinal displacement assembly (47) is used by the control systems to move the cartridge, after   attachment, out of the cell or optical drive. After positioning the cartridge vertically and laterally, the longitudinal displacement assembly (47) is then used to move the cartridge into a cell or the optical drive, where the engaging assembly (45) releases the cartridge. An important aspect of the invention is that the longitudinal displacement assembly (47), the flip assembly (49), the lateral displacement assembly (51), the engagement assembly (45), and the mailslot assembly (41) are operated by one of the two control systems. The other of the two control systems is used for vertical displacement of the cartridge.

Abstract: This invention is a technique for the substantially instantaneous self-healing of digital communications networks. Digital data streams from each of N nearby sources are combined and encoded to produce N+M coded data streams using a coding algorithm. The N+M coded data streams are then each transmitted over a separate long haul communications link to a decoder where any N of the N+M coded data streams can be decoded uniquely to produce the original N data steams. The original N data streams are then distributed to their respective separate end destinations. If any M or less of the N+M long haul communications links falls, i.e. as in a telephone line that gets cut or a long distance switch that fails, no rerouting of traffic need be done. Rather, the receiver detects loss of carrier on the failed link(s), and immediately supplies the missing data by decoding the data from the at least N remaining links. The technique overcomes a long felt problem of trying to reroute traffic by using sophisticated resource allocation techniques when a communications link fails.

Abstract: In a preferred embodiment of the invention, a process is disclosed for producing a compound aluminium alloy engine block casting (10) which comprises at least a piston-travel region (26) of a cylinder wall section (18) formed of a first alloy, preferably hyper-eutectic aluminium-silicon alloy, and a remainder including a crankcase section (12) and a water jacket wall (20) formed of a distinct second alloy, preferably hypo-eutectic aluminium-silicon alloy. The engine block casting (10) is made by a lost-foam process that employs an expendable pattern (32) formed of expanded polystyrene or the like. The pattern comprises a first runner system (50) for casting the first alloy to decompose and replace a portion of the pattern corresponding to the piston-travel region (26) of the casting, and a second runner system (60) for casting the second alloy to decompose and replace the remainder of the pattern (32). The first alloy and the second alloy are independently but concurrently cast into a single mould (30), such that the entire pattern (32) is duplicated, whereupon the alloys merge and fuse to form an integral casting (10). The preferred product engine block casting (10) advantageously combines the high wear-resistance of the hyper-eutectic aluminium alloy in the cylinder wall section (18) and the reduced porosity and improved machinability of the hypo-eutectic alloy throughout the balance of the casting (10).

Abstract: Apparatus and methods for measuring response of a chemical composition to light, as by frequency domain, phase angle, or modulation fluorometry and/or phosphorimetry. Pulsed light having a known fundamental frequency is applied to the composition thereby eliciting response light varying at the fundamental frequency and at harmonics thereof. The response light signal may be sampled according to a wave-skipping sampling scheme, and the sampled response signal may be transformed into a frequency domain representation, as by a digital fast Fourier transform technique. A reference signal derived from the excitation light may be similarly processed and the results used as a basis for comparison to derive properties of the chemical composition such as phase and modulation response of the composition to the fundamental and harmonic frequencies. The invention provides rapid monitoring and determination of luminescence characteristics. Multiple excitation frequencies may be applied simultaneously and the resulting response signals may be separated and separately sampled.
