Abstract: ABSTRACT OF THE DISCLOSURE        An electrostatic coating machine comprises a coating machine main body having a rotary atomizing head and a cleaning shroud, a plurality of color change valve mechanisms for feeding paints and cleaning fluids to the rotary atomizing head, a first change-over valve provided at a position close to the rotary atomizing head, paint feed passages respectively connected to each of the color change valve mechanisms and selectively communicating with the rotary atomizing head by way of the first change-over valve, a drain passage for recovering the drainage from the cleaning shroud and the first change-over valve, a discharging section for forcively discharging the drainage from the drain passage, and a second change-over valve provided in the midway of the drain passage communicating from the cleaning shroud to the discharging section. The cleaning shroud, the first and second change-over valves are disposed in a high voltage section that takes the same potential as that for the rotary atomizing head when a high voltage is applied to the rotary atomizing head, whereas each of color change valve mechanisms and the discharging section are disposed on the side of the ground.  The method of changing color of paints using the foregoing electrostatic coating machine is also disclosed.

Abstract: METHOD FOR CONVERTING ONE FORM OF ENERGY INTO ANOTHER FORM OF ENERGY          Abstract of the Disclosure Method for converting one form of energy into another form of energy by isobarically heating a gas, adiabatically expanding the gas while converting the heat energy of the gas into the kinetic energy of a moving body, converting the kinetic energy of the mov-ing body into another form of energy, and approximately isothermally compressing the gas to a higher pressure. Improved efficiency is achieved by virtue of the fact that this system employs approximately isothermal com-pression, which is preferably achieved by injecting liquid into an adiabatically-expanded gas, thereby ef-fecting a thermodynamic cycle which more closely ap-proximates the efficiency of a Carnot cycle.

Abstract: ABSTRACT: Arrangement for correcting pulse distortion in homochronous data transmission".           In the duplex transmission of data signals over two-wire transmission paths the phenomenon of echo-signals is encountered, while simultaneously intersymbol inter-ference occurs between the data symbols themselves. In order to reduce the influence of both the echo signals and the intersymbol interference, the arrangement comprises a random access memory (16) which produces a correction value(c(i)) at each sampling instant to correct the received data signal. The memory is addressed from registers (13, 14) and a counter (15), the contents of the registers being determined by the data symbols transmitted last and the data symbols received last, respectively. A D-A converter (19) converts the correction value into a correction signal (c(t)), which in a diffe-rence producer (20) is subtracted from the received dats signal A sampling arrangement (21) samples the corrected received data signal. After D-A conversion (22) and multiplication (17) by a predetermined factor .alpha. each sample furnishes a number by which the correction value is changed to match it to the value of the pulse distortion at the sampling instant.

Abstract: Abstract In one form of stripline antenna, the strip turns through successive right-angle corners to form successive multi-cornered cells in which the lengths of the longitudinal and transverse strip sections are such that the summed radiation from each cell radiates in the same direction and with the same polarisation direction, eg as described in Canadian Patent Application No. 331,541 Filed July 10, 1979.  In the present disclosure, the distribution of radiated power along the array is varied, eg to maximise it at the centre, by varying the absolute lengths of these strip sections as between cells while maintaining their required relationships, eg by progressively increasing these lengths towards the centre of the array in order to increase the radiated power accordingly. This compares with the previously known method, viz varying the strip width.

Abstract: ABSTRACT OF THE DISCLOSURE             A vending or dispensing machine is disposable in modes for triple depth dispensing, double depth dispensing, and single depth dispensing.  Upper and lower gating members or rockers are used to selectively release cylindrical articles such as cans or bottles from a storage compartment containing staggered tandem columns into a consumer accessible dispensing zone.  The upper and lower rockers are moved by a drive plate which causes reciproca-tion of the rockers by way of drive pins.  Removable retaining members are used for preventing premature release of center column cans and also provide an anti-theft feature.  A removable gating piece is used to prevent the premature release of a rear column can.  A freely swinging anti-theft bar has a stepped portion which keeps a can from being axially slid in the escrow zone disposed between the storage compartment and the dispensing zone, thereby preventing the unauthorized removal of the can.  A timer cam which is programmed by adjustable cover plates is used for changing the mode for different depth operations.

Abstract: OIL COOLING APPARATUS FOR REFRIGERATION SCREW COMPRESSOR               Abstract of the Disclosure The invention relates to improvements in a refrigeration system having an oil cooled screw compressor from which mixed oil and compressed refrigerant issues to an oil separator via a discharge duct, and wherein a re-frigerant pump draws liquid refrigerant from the high pressure receiver and delivers it to the discharge duct to cool the oil and desuperheat the refrigerant.  The refrigerant pump and a hydraulic motor that drives it are in a single sealed housing.  The hydraulic motor is ener-gized with pressure oil from the oil pump whereby oil is returned to the compressor from the oil separator.  Oil flow to the hydraulic motor is throttled in accordance with output from a temperature sensor at the discharge duct, to maintain a constant temperature of oil-refrigerant mixture passing to the oil separator.  A standpipe arrange-ment prevents cavitation at the refrigerant pump.
