Abstract: PROCESS FOR PURIFYING AND RECOVERING CONTAMINATED CATALYST SOLUTION OBTAINED IN THE CARBONYLATION OF METHYL ACETATE                 AND/OR DIMETHYLETHER       ABSTRACT OF THE DISCLOSURE The disclosure relates to a process for purifying and recovering a contaminated catalyst solution which is ob-tained in the carbonylation of methyl acetate and/or di-methylether, the catalyst solution containing carbonyl com-plexes of noble metals of group VIII of the Periodic System of the elements, quaternary heterocyclic aromatic nitrogen compounds or quaternary organophosphorus compounds as orga-nic promoters, undistillable organic contaminants as well as acetic acid, acetic anhydride and ethylidene diacetate. To this end, the disclosure provides for the catalyst solu-tion to be distillatively freed from its volatile consti-tuents and for the remaining solid distillation residue to be water-treated, the noble metal/carbonyl-complex being precipitated together with the organic contaminants and the organic promoter becoming dissolved; for the precipi-tated and contaminated noble metal/carbonyl-complex  to be removed by filtration and to be freed from the organic con-taminants by extraction with aliphatic ethers; for the organic promoter to be recovered by evaporating the water or extracting it with halogenated hydrocarbons and for these latter to be  evaporated; and for the purified noble metal/carbonyl-complex and the recovered organic promoter to be recycled into the carbonylation reaction.

Abstract: A B S T R A C T     This invention is an arrangement for driving a multi-phase switched reluctance motor from a two-point d.v. supply (11) in which capacitors (12) and (13) are provided across the supply with their common point (14) constituting a third power supply point.  The load windings W1, W3, W5 and W2, W4, W6 are connected in two different load circuits connected across the different capacitors, and arrangements including diodes D1 - D6 are provided for enabling a winding to return energy to the supply when it is not being used to provide driving torque. In order to prevent the voltage of the third point wandering because the currents in the two load circuits are not the same, voltage metering means (M3, M4 or M5, or N1, N2) are provided, and they tend to compensate for any variation in the potential of the common point.  Control means (21) can control the distribution of current between the various load windings by appropriate control of semi-conductor switches in the various load circuits.

Abstract: ABSTRACT       A movable inner cylindrical valve member is rigidly attached to the upper end of an air powered impact projectile designed for striking a target to produce an acoustic pulse.          By seating upwardly within the bore of a fixed outer valve member against spaced apart tapered valve faces, the cylindrical wall of the inner valve member covers intermediate air pressure ports in the bore wall.  In operation, the axial separating movement between the inner and outer valve members will instantly admit air pressure adjacent the closed end of the bore of the outer valve member in order to exert an accelerating force to drive the projectile.  At the same time, the operation of this valve can be made essentially pressure independent by proper selection and placement of the annular seals which contact the valve faces.

Abstract: ABSTRACT OF THE DISCLOSURE    A submersible pump electrical motor has 3 rotor that is divided  into sections, and a bearing located between each  of  the  sections for  maintaining  the  shaft of the rotor in axial alignment.  The bearing assembly includes a sleeve that is keyed to the shaft. A  bearing has an inner portion that  rotatably receives the sleeve.   The bearing has a  flange with a periphery that  frictionally  engages the  stator  to  prevent  the  bearing  from  rotating. The sleeve physically contacts the adjacent rotor sections and transmits forces between them.  Thrust washers are located between upper and lower edges of the bearing inner portion for supporting the bearing.  The thrust washers have inner diameters that receive the sleeve.

Abstract: SUPERMARKET ENVIRONMENTAL CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE     An air temperature regulating or conditioning control apparatus for use in a space having one or more refrigerated display fixtures.  The fixtures have an open refrigerated display zone separated from the conditioned room space by one or more planes (curtains) of refrigerated air substantially lower in temperature than the conditioned room space, which absorb energy from the room air adjacent these planes thereby causing it to be cooled.  The apparatus comprises a housing having a return air chamber and a make-up air chamber isolated from the return air chamber.  Each of these parallel chambers has an outlet connected to a mixing compartment  for mixing the conditioned air received from both chambers.  An air moving means is connected to the mixing compartment for displacing the mixed conditioned air through air flow convection ducts back into the space.  Each of the chambers further has an air intake or inlet, a filter section and  a cooling section.  The inlet of the return air chamber is supplied primarily with air cooled by the refri-gerated display fixtures.  The room space is maintained at a substantially constant temperature throughout unaffected by the refrigeration effect of the display fixtures upon the room space air.

A switch 16 selects input, output and fault modes.  The input mode causes those LEDs 12 corresponding to input channels where an input signal is present to be illuminated.  The output mode causes those LEDs 12 corresponding to output channels where an output signal is present to be illuminated.  The fault mode causes illumination of LEDs corresponding to input channels where an input is required by the current program step but no such input is present.

Abstract: Abstract of the Disclosure An acid alkylation process is controlled so as to maintain a desired ratio of isobutane to olefins in a fluid stream flowing to the alkylation reactor and to maintain a desired acid to hydrocarbon ratio in the  alkylation  reactor.   Also,  if  parallel  alkylation  reactors  are utilized, the flow rate of the olefin stream to one of the alkylation reactors  is manipulated so as  to maintain a balanced loading on the parallel alkylation reactors.  Such control results in improved quality of  the  alkylate  produced  and  also  improves  the  amount  of  alkylate produced from a particular amount of fluid to the alkylation reactor.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved electronic control system in a glassware forming machine is disclosed.  The machine has a plurality of individual glassware forming sections each having a plurality of glassware forming mechanisms.  The machine also has means for feeding and sequentially distributing gobs of molten glass to each of the individual sections in an ordered sequence over one machine cycle consisting of a fixed number of clock pulses to form the gobs into glassware articles by cycling the forming mechanisms in a predetermined sequence of forming steps.  Each individual section has an associated electronic control system responsive to each clock pulse for providing a load signal and a plurality of forming signals to actuate the forming mechanisms during the machine cycle.  Finally, the machine has a circuit for providing a gob load signal in response to a load signal from any one of the control systems and means responsive to the absence of a gob load signal for deflecting a gob to prevent it from being distributed to an individual section.  Each improved control system comprises means for providing an operation pulse each time the control system provides a plurality of forming signals to the forming mechanisms and means for providing a monitoring signal at a first binary state when a first one of the operation pulses is applied thereto and changing to the second binary state if no operation pulse occurs within a predetermined stall-period of time after the first operation pulse.  Each improved control system also comprises means for enabling the load signal and the forming signals when the monitoring signal is at the first binary state and for inhibiting the load signal and the forming signals when said monitoring signal is at the second binary state so that the gobs of molten glass will not be distributed to the individual sections and the forming mechanisms will. return to a safe condition.
