The starting winding of a single-phase asynchronous motor is connected to supply by a capacitor having a negative temperature coefficient of capacitance such that as the dielectric warms up the capacitance drops from a value suitable for starting to one suitable for running. The capacitor may be heated by the current passing through it (Fig. 1, not shown), by radiation from the motor, or by a separate heater (11, Fig. 2, not shown), in series with the main winding of the motor. The capacitor may be insulated against heat dissipation.

Abstract: 1516198 Particle size analysis by scattering BAYER AG 19 Aug 1975 [23 Aug 1974] 34397/75 Heading G1A A process for particle size analysis comprises the measurement of the frequency spectrum of scattered laser light for each of a plurality of scattering angles #, generating from each spectrum a plurality of physical representations of particle diameter d i  from which parameters of average particle diameter d and the width of the band of particle size distribution # are generated using a logarithmic normal distribution of the representations using the method of least squares. Apparatus for this comprises a spectrometer with a measuring vessel 1 or 8, photo-detector 11 for coherent demodulation of the scattered light, a frequency analyzer 13 comprising a plurality of fixed frequency filters in parallel with their outputs scanned by scanner 14 and digitized and transmitted to computer 15 for determining d and #, operating in real time and controlling the measuring process. Vessel 1 has tube 3 for sucking off the measuring liquid 5 and introducing washing liquids. Black glass tube 2 absorbs the primary beam 4 from HeNe laser 6, Fig. 6, (# 0  = 0À6328 Ám). The aperture is reduced by double shutter 10 so that the effective area of photo-multiplier 11 is one coherence surface. The homodyne beat frequencies of its output pass via amplifier 12 to analogue or digital analyzer 13 whose scanned output is stored in computer 15, which calculates the diameter d, of each particle corresponding to #v 1  and K and from these values of d 1  calculates #v, d and # by adjusting a logarithmic normal distribution of values by the method of least squares. The computer output is recorded by printer 16 and the operating dialogue by operating unit 17. The computer closes diaphragm 9 to find the noise level, adjusts # 1 , optimizes the amplification of amplifier 12, adjusts the integration time of filter 13, and the number, frequency and sequence of scans, and monitors for overloading.

[Class 29] [See also Group XXIX] Cream &c. is frozen in a vessel 17 having a refrigerant evaporator jacket 15 to which liquid refrigerant from the reservoir 6 of an absorption machine is admitted through a valve 10 connected with the vapour outlet valve 11 of the jacket so that when either valve is opened the other is closed. Upon closure of the valve 10 vaporization takes place in the jacket until the cream reaches a desired plasticity whereupon the valve 11 is closed and relatively warm liquid refrigerant admitted to the jacket through the valve 10. The operation of the valves may be controlled automatically through linkage 35, Fig. 2, connected to the armature 38 of a solenoid 39 in the circuit of an ammeter 40 through which current is supplied to the motor 21 of a rotary stirrer 20 in the freezing vessel 17. When the resistance to the stirrer becomes excessive, the pointer of the ammeter contacts with the stop 41 and completes the circuit through the solenoid and thus effects opening of the valve 10 and closure of the valve 11. The absorption refrigerating-machine comprises a generator-absorber 1, condenser 4, and reservoir 6 provided with a gauge 7. By opening the valves 10, 11, 13, 44, solvent may be drained from the evaporator jacket to the generator-absorber.

A central roller d bears against all of the rollers e and supports them against the thrust of the material being extruded. The ring a may rotate on a axis disposed otherwise than vertically, but, as shown, the axis is vertical and the drive is effected by a gear wheel i which is meshed with an internally toothed wheel h connected to the bottom plate c. The rollers e are carried on shafts e<1> journalled in eccentric bushes x in the fixed cover k, the eccentric bushes x permitting the replacement of worn rollers e by oversized rollers, the central roller d then being replaced by a corresponding smaller roller. The central roller d is arranged to float between the rollers e, being supported on a rounded projection on a shaft g which carries the ring die a, and being held down by a peg u.

[Class 80 (iv)] The guard according to the parent Specification is modified in that one only of the guard bars reciprocates, the other being stationary; also in that two reciprocating bars may be actuated by a rock shaft, or carried on an endless chain. In the device shown in Fig. 1, the stationary bar 10 is secured at the lower ends of side bars 12 which hang down from a shaft 13, and the moving bar 11 is,guided on the bars 12 by shoes 16. In a modified construction the stationary bar connects the bars 12 immediately above a slot in the bars in which the moving bar reciprocates.
