Title: Improvements in or relating to absorption refrigerating machines
IPC: F25B15/00
Filed: 1927-05-11
Abstract: 272,868. Sulzer FrÞres Soc. Anon. June 17, 1926, [Convention date]. Refrigerating, absorption machines for.- The refrigerant is absorbed, generated and condensed in two or more stages and the heat liberated during condensation in the higher-pressure stages and absorption at the higher temperatures is utilized for generation in the lower-pressure stages. The refrigerant vapour passes from the gas heated high-pressure generator 1, Fig. 7, through a pipe 3 to the condenser 4 in the lowpressure generator 5 and thence through the pipe 6, tank 9 and the pipe 7 to the condenser 8 from which it returns to the tank. From the tank, the refrigerant passes through a float-controlled valve to the condenser 11 which also receives the vapour from the low-pressure generator 5 through the pipe 12. The liquid refrigerant passes through the expansion valves 13 to the evaporator 14, whence the vapour passes to the pipe 17 and there meets solvents flowing upwardly from the coil 18 in the high pressure generator through a float valve and a tank 19. The refrigerant vapour and the solvent flow through the absorber 20 in the low-pressure generator to the absorber 22 and the tank 23, from which the strong-liquor is forced by the pump 24 through the heat interchanger 25 to the generator 5. The liquor thence flows through the pipe 27 to the tank 28 from which it is withdrawn by the pump 31 and returned to the high-pressure generator. In a modification, the generation is effected in three stages and the liquor is pumped directly into the high-pressure generator, its passage through the other parts of the apparatus being automatically governed by float-controlled valves. In this case, heat interchangers are disposed between the generators on the strong-liquor side of the apparatus.

Title: Transmission of frequency modulated valves
IPC: H03C3/06
Filed: 1939-04-28
Abstract: 528,152. Frequency modulation. STANDARD TELEPHONES & CABLES, Ltd. April 28, 1939, No. 12788. Convention date, May 21, 1938. [Class 40 (v)'] Frequency-modulated signals are received by combining them with locally-generated waves in phase-quadrature, and thereafter utilizing any component resulting from lack of frequency and phase-quadrature agreement to maintain the phase-quadrature relation, and at the same time to produce a demodulated current. Incoming signals are fed from a transformer 5 to balanced detectors 7, 8. The parallel input winding 9 is coupled to the output circuit of a variablefrequency oscillator 12, the back-coupled grid circuit of which includes a winding 14, with a magnetic core, and a control winding 16. The latter is in series with a coil 20 which is coupled to a network 19, tuned to the carrier-frequency and shunted across the signal input. Normally the oscillator 12 supplies a carrier-frequency oscillation to the coil 9 in phase-quadrature with the signals. This leaves the series coils 16, 20 unaffected. The arrival of a frequency-modulated signal, however, increases the spac:e-current say through detector 7, at the expense of detector 8, and so produces a control voltage across the resistances 22, 23. This alters the biasing current through the coil 16 and causes the tuning of the circuit 13 to keep in step with the changing frequency of the incoming signals, thus automatically maintaining the locally-generated oscillations in the required phase-quadrature. At the same time, voltages corresponding with the original signal appear across the series resistance 26. The band-pass action of the circuit 19 also automatically keeps in step with the shifting frequency of the incoming signals.

Abstract: 475,035. Moulding lenses &c. WILLIAMS, W. E. May 7, 1936, No. 12870. [Class 87 (ii)] [Also in Group XX] In forming lenses, mirrors and other optical devices, particularly lenses of large aperture ratio, from plastic material such as synthetic resin by hot - pressing at moderate temperature between optically polished dies, the die is formed with a truly spherical surface, one or more preliminary lenses are moulded therewith, the departure of such lenses, on cooling, from the required spherical surface is assessed by interferometrical tests and the die is locally polished in accordance with the assessment and used to produce a resultant lens having the required truly spherical shape. Unequal cooling of parts of the lens and consequent distortion are thus corrected for. Alternatively, an aspherical lens may be moulded by forming the die initially with approximately the required aspherical surface and determining the correction required for local polishing from a preliminary lens in the same manner. For a plano-convex lens 1, the die 2 may have a truly spherical surface and the blackened portions 4 may be removed so as to give it an aspherical surface whereby the surface of the resultant lens is spherical. Or the die may be such as to produce a resultant aspherical surface. The amount of polishing can be determined by use of an interferometer such as described in Specification 474,809, [Group XX]. Specification 416,398, [Group XX], also is referred to.
