A container e.g. a beer barrel, comprises two cup-shaped end members 2, 4 compression moulded from a polyester resin mixture containing glass fibres lying at random, the end members being joined by means of adhesively. coated screw threads, either directly or indirectly through a tubular part 6. The screwthreaded parts may be tapered. As shown, the joints between the part 6 and its adjacent end member are surrounded by a nylon ring 10 under tension, to which is adhered a rubber ring 12. A ring 24 of metal is riveted to integral lugs 30 on the end member 4, and a metal plate riveted to the member 2. A clip 16 is bolted to the container interior as a seating for the lower end of a discharge pipe 22 held at its upper end by a fitting 14. The container interior may be coated with an epoxy-phenolic lacquer. Washing and filling.-Before filling, the container is inverted over a washing nozzle, the pipe 22 and associated fitting 20 having been removed. The container is filled through a pipe (not shown) having a bayonet connection with the fitting 20, the pipe pushing the tube 22 against a spring so that the lower end of the pipe engages a metal contact 40. An electric circuit is thereby established from the supply pipe via the members 22, 40 to a metal strip 42 forming part of the plate 36 which is in electrical contact with the filling-machine. A measured quantity of beer is thereby filled into the container.

Title: An improved method of indicating frequency changes, in alternating electric currents
IPC: G01R23/00
Filed: 1925-02-04
Abstract: 244,607. Western Electric Co., Ltd., (Western Electric Co., Inc.). Feb. 4, 1925. Frequency, measuring.-Small changes in the frequency generated by a source of alternating current are indicated by a system comprising a pair of networks supplied by a part of the energy generated by the source, one of the networks having a transmission characteristic such that a change in attenuation is effected by a change in frequency, while the attenuation of the other network is either independent of the frequency or is opposite to that of the :first, and an indicating device associated with both networks for comparing the potentials derived from the networks. As shown, one of the networks comprises a filter 9 which transmits frequencies below a critical value while sharply attenuating frequencies above this value, and is connected to bus-bars 5, 6 through a change-over switch 3 and resistance 8. The other network comprises an artificial line 10. A pair of rectifiers, such as detector valves 11, 13, or thermo-couples, are coupled to the networks by means of transformers 12, 14, and are connected in a balanced circuit including a sensitive galvanometer which indicates changes in the potentials, or the system shown, in which a light 19 is lit when the frequency is normal, or coloured lights 20, 21 when the frequency rises or falls. This system comprises equal batteries 22, 23, each capable of lighting a lamp to medium brightness. Resistances 24, 25 are in shunt with the lamps 20, 21. The circuits are controlled by a pair of triple winding relays 26, 27, wound as shown. In the position shown the lamp 19 is fully lit indicating that the frequency is normal. Variation of the frequency effects movement of one or other of the armatures and lights the lamps 20 or 21. An alternative circuit 4, similar to the artificial circuit 10, may replace the filter 9 when it is desired to renew the filter. The apparatus may be used for detecting variations in frequency in a wireless transmitting system. For this purpose, the antenna is connected to earth in series with the primary winding of a transformer, the secondary of which is connected to the input of a balanced modulator where the waves are combined with a carrier wave generated by a constant wave source in circuit with the third winding of the transformer. The output of the modulator is impressed upon an amplifier connected to the input circuits of two filters, or a filter and artificial line, in parallel.
