Abstract: The polymeric ingredient of the inventive-rubber composi­tion is an acrylic polymer modified with a mercapto-containing or­ganopolysiloxane by the emulsion polymerization of an acrylic monomer in an aqueous emulsion of the organopolysiloxane. Cha­racteristically, the acrylic monomer is copolymerized with another monomer having an active halogen atom or an epoxy group. By virtue of this unique formulation of the rubbery polymer, the in­ventive rubber composition prepared by compounding the rubbery polymer with a reinforcing filler and a curing agent can be vulcan­ized to give a vulcanizate having excellent mechanical properties, heat resistance, oil resistance and cold resistance as a combination of the features of silicone rubbers and acrylic rubbers.

Abstract: The specification discloses an apparatus for rapidly cooking meat products for a quick service restaurant which will simulate the appearance of an open flame broiled meat product. The meat product is clamped between a grill (13) and a series of raised crown portions (22) formed in a cooking pan (11). The cooking pan also includes rounded depressions (23) which alternate with the upraised crowns to serve as reservoirs for the collection of fat and other rendered meat juices. The clamping action between the grill and the pan flattens the meat product having a range of product weight to a uniform thickness while simultaneously assuring conductive heat transfer from the crowns to the meat. The grill is pre-coated with a carmelizing agent which leaves grill marks on the meat product during the cooking cycle. The grill, meat product and pan can be conveyed through an air impingement oven having a plurality of heated high velocity air jets (21) which impinge on the meat product, displace a food product boundary layer of cool air, and evenly heat the irregular surface of the meat product as it passes through the jets. Alternatively, the grill, meat product and pan are loaded into a convection oven having means for creating heated high velocity convecting air which contacts the meat product, displace a food product boundary layer of cool air, and evenly heat the irregular surface of the meat product as heated air passes over it.

Abstract: A phase comparator (11) has a switching circuit (12) controlled by a switch signal (SW) and a phase com­paring unit (13). The switching circuit (12) receives a reference pulse signal having a duty ratio of 50% and a reception data signal having a duty ratio of less than 50%. One of these signals is selected by the switching circuit (12) on the basis of control of the switch signal (SW). The selected signal and an output signal from a voltage-controlled oscillator are supplied to the phase comparing unit (13). The phase comparing unit (13) compares phases of the two signals. When the phase of the output signal from the voltage-controlled oscillator (16) lags behind the phase of the selected reference pulse signal or reception data signal, the phase comparing unit (13) outputs a first pulse signal (CS1), having a width corresponding to a phase dif­ference between the two signals, for advancing the phase of the output signal from the voltage-controlled oscillator (16). When the phase of the output signal from the voltage-controlled oscillator (16) leads ahead of the phase of the selected reference pulse signal or reception data signal, the phase comparator (13) outputs a second pulse signal (CS2), having a width corre­sponding to a phase difference between the two signals, for delaying the phase of the output signal from the voltage-controlled oscillator.

Abstract: An infusion pump includes a system for sensing the near end and end of syringe positions of a piston 6 in a syringe 12 by means of a permanent magnet 14 located in a disengagement head 8. The magnet 14 as it passes a switch 16 located adjacent the syringe 12 within the pump case, closes the switch 16 thereby transmitting a signal to a microprocessor 20. The signal when received by the microprocessor 20 causes the microprocessor 20 to store pulses coming from the infusion pump motor encoder 22. The sum of the pulses received from the encoder 22 is compared with a preset value which once reached causes an alarm to be operated thereby indicating a near end or end of syringe position of the syringe piston 6 relative to the syringe 12.
