Abstract: 520,074. Distributing music &c. WIRED RADIO, Inc. Aug. 10 1938, No. 23565. Convention date, Aug. 28, 1937. [Class 40 (iv)] [Also in Group XL] In a system for distributing a number of programmes over an existing network, e.g., the power network of a building, employing single side-band carrier transmission, the signal currents are fed from a common output circuit through a transformer 93 and a coupling network 28 which are designed so that the distribution network presents a uniform resistance at representative frequencies in the several programme channels. The various turn ratios of the transformer 93 are determined in accordance with the measured values of the conductance of the distribution network at the representative frequencies, e.g., the carrier frequencies. while the inductances 100 and capacities 105 are chosen so that they balance the measured reactances at those frequencies. The carrier frequencies are supplied by a harmonic generator,. and after modulation the lower side-band of each channel is fed through amplifiers to a composite filter network 31, which comprises individual sections 60, 61 and a common twoterminal section 62 which balances the reactances of the channels. The signal currents are applied at the output of the coupling network 28 to the power bus wires of a building, and these feed through control panels a number of vertical cables, each of which supplies a section of the building comprising a similar partial area on a number of floors. The Specification gives in a numerical example suitable values for the elements of the filter network 31 and coupling network 28 and for the turn ratios of the transformer 93 for supplying to a given distribution network five programmes on carriers of 26, 39, 52, 65 and 78 kilocycles.

Abstract: 1,271,895. Antiskid braking systems. GENERAL MOTORS-HOLDEN'S PTY. Ltd. 21 May, 1970 [9 June, 1969], No. 24592/70. Head- F2F. [Also in Division F1] An hydraulic braking system for road vehicles for preventing wheel lock has a cam 3 driven by a rotary shaft of the drive system and which is dependent upon the rotational velocity of the vehicle wheels and actuates a piston 9 engaging a diaphragm 8 to pump liquid from a pumping chamber 7 via a one way valve 13 to a pressure chamber 14 of an hydraulic pressure modulator 33 the pressure in which controls the movement of a spring-biased piston 23 engaging a member 28 carrying a valve 22 which controls hydraulic pressure from a master cylinder through a pipe 19 to wheel cylinders through a pipe 21. The force exerted by a spring 29 on piston 23 is sufficient in normal braking to hold valve 22 open but when the wheel speed decreases beyond a predetermined valve the pressure in chamber 14 which forms a closed circuit with chamber 7 by way of orifice 16, passage 17 and one-way valve 12, chamber 7 being in communication with a reservoir 18 through an orifice 34, descreases and master cylinder pressure causes valve 22 to seat thereby closing off communication with the wheel cylinders. Further reduction in wheel speed results in piston 23 being retracted further to increase the volume of a chamber 14a and decrease the wheel cylinder pressure. The modulator system may be applied to all, or the rear wheels only and cam 3 may be driven off of a wheel axle or propeller shaft. Modulator 33 may be provided as a single unit for all wheels or a single modulator provided for each wheel.
