Abstract: A high efficient gas fired frying apparatus for deep frying food is disclosed. The gas fired frying apparatus is comprised of a supply system for air and fuel gas, a compression system, a burner system, a combustion chamber, a heat exchanger and an exhaust system. The air and fuel gas are mixed and pressurized prior to being introduced to the burner system. The burner system works in conjunction with the combustion chamber to support combustion by balancing the premixture velocity with the flame velocity such that smooth and complete combustion occurs. The high velocity components of combustion are directed through a heat exchanger which transfers the heat to the cooking oil. The exhaust system recovers additional energy from the products of combustion and a catalytic converter may be added for removal of unwanted pollutants. Both the combustion chamber and the heat exchanger are removably disposed within the frypot to facilitate cleaning and oil replacement.

Abstract: A sheave structure adapted to prevent the build-up of soil and other foreign materials in the v-grooves of sheaves utilized with ground engaging implements such as rotary tillers is provided.  The sheave is constructed of mating halves, which when joined form a sheave with a v-groove that includes circumferentially spaced apart openings in the v-groove apex, below the belt contact area of the flanges. The openings are provided adjacent to, but below the belt contact area so that the  belt pushes against any materials that collect in the v-groove. In this way, the belt serves to break apart the materials and push them through the openings.  With this structure, accumulations of materials in the sheave are minimized, belt contact with the sheave flanges is improved and power transmission is enhanced.

Abstract: Reservoir flow or surge control systems frequently have large installed lifting or pumping capacity to deal with variations in either inflow or outflow, or both, and may form a part of a larger system of many such reservoirs (20, 120).  Taken together these reservoirs may have significant storage capacity.  In operation such systems are large consumers of electricity.  Electricity is often priced differently at different times of day. This invention employs this storage capacity to permit energy consumption to be shifted, at least in part, from periods of high electricity prices to periods of low electricity prices.  This is done by permitting a greater amount of material to collect during periods of expensive electricity, and then removing the material to a lower level during periods of less expensive electricity, or the reverse, depending on the nature of the system and the material in question.  Either an 'On - Off' or flow rate control method of pump control may be used.  The invention is illustrated by application to a wastewater pumping system (10).  In this case a control unit (70) works in conjunction with a pulse-echo acoustic level sensor (40) to control the operation of a battery of wastewater pumps (32-35) at wastewater pumping stations in an urban sewage system.

Abstract: The aim of the intention is to provide a method which makes it possible to mount an external potential-control device in place on an individual bar before the bar is impregnated with high-electric resin. The method is used in the manufacture of bars, fitted with a potential-control device, for bar-wound high voltage windings for a rotating electric machine, the method calling for the bar (5) to be covered with insulation (1) and provided with a conducting layer. The part of the bar (5) which fits into the bar-mounting groove is wrapped with a strip (3) having a known, low resistance, and the coil-end projection is wrapped with a strip having a resistance which is dependent on the voltage. This bar (5) is inserted in a calibrated mould for impregnation and subsequent curing, the part of the bar (5) which fits into the mounting groove being covered by protective foil (4). The invention makes it possible for the first time to impregnate the potential-control device with the insulation, thus integrating it with the insulation. This ensures an extremely high resistance to wear in addition to good electrical conductivity. Furthermore, it is possible to examine individual bars closely before they are mounted in place and also to record the potential-control measured values.

Abstract: A method and apparatus for generating ultrashort optical pulses.   The apparatus comprises a source for producing pulses in a first band, a compensating optical fibre, and a span of dispersion-shifted optical fibre.  The compensating optical fibre receives the pulses generated by the source and has a minimum dispersion in a second band different   from   the   first   band   and  dispersion characteristics for compensating phase distortion due to chirp of the pulses.  The dispersion-shifted optical fibre is coupled in series to the compensating optical fibre and has a dispersion minimum in the first band for adjusting the peak power level of the pulses emitted by the source to produce self-phase modulation in the dispersion-shifted fibre.  Pulse peak power is selected so as to coincide with the vertex of the parabola plotting the square of the duration of the outgoing pulse versus the peak power of the incoming signal.
