Abstract: 405,244. Piston apparatus for distharging-receptacles. DOZO, J., 40, Rue Louis Hymans, Brussels. April 28, 1932, No. 12274. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 23, 1933]. [Class 102 (ii).] In a reservoir shaving brush, toilet cream tube, grease pump, or like dispensing device of the type in which the contents are delivered by means of a sliding piston co-operating with a screw-threaded spindle, the spindle may be disconnected from its actuating member when the piston reaches the end of its stroke, withdrawn from the container together with the piston, reversed and restored to the container, so that the device is then in a condition to be refilled. In the construction shown in Fig. 1, a piston 2 held against rotation by a rib 3 is engaged by a screw-threaded spindle 4 operated by a cap 6. The ends 4a, 4b of the spindle are similar, each being adapted for engagement in a boss 5 on the cap 6. The head of the brush is detachable to enable the spindle 4 to be withdrawn and reversed when the handle 1 requires refilling. If the handle is to be refilled from a tube of shaving cream, the tube may be fitted with a long nozzle adapted to reach to the bottom of the handle. Fig. 6 shows a grease pump the spindle 4 of which is similarly formed at each end for engagement by the boss 5 on the actuating handle 18. A device for dispensing soft soap is shown in Fig. 7, the soap being delivered through a goose-neck tube 21. The piston instead of forcing the soap downwardly may be adapted to compress it during its upward stroke, expelling it through an opening at the top of the container.

Abstract: 455,649. Wireless receivers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, and LINSELL, A. A., 80, Crystal Palace Park Road, Sydenham, both in London. April 26, 1935, No. 12558. [Class 40 (v)] A receiver operating over a short wave television range and as a sound broadcast receiver is provided with means on switching to television to broaden the frequency response of the sound broadcast receiving apparatus which is employed as an intermediate frequency amplifier so as to pass the relatively wide band of frequencies occupied by television signals and to fix the tuning of the broadcast receiver. The Figure shows a supersonic heterodyne broadcast receiver preceded by a short wave frequency changer 3 so that the signal frequency circuits of the broadcast receiver serve as the intermediate frequency amplifier on short waves. The broadcast receiver is tuned to the required frequency and its frequency response increased to pass the sideband frequencies required in television by switches 10, 10<1> which replace the variable tuning condensers by fixed condensers and insert damping resistances 12, 12<1> while the response in the intermediate frequency amplifier is increased by damping resistance 16. Instead of shunt resistances series resistances or combinations of resistance, inductance and capacity may be used to broaden the response band of the receiver, alternatively the grid bias may be adjusted to vary the valve damping. In a modification, Figs. 2 and 3 (not shown), the switch operation is conjoint with the tuning control being operated when this control is adjusted to a predetermined, e.g. minimum wavelength position. The fixed tuning capacities may be formed by the self capacity of the coils.

Filed: 1938-05-02
Abstract: 514,317. Multiplex transmission. SIEMENS BROS. & CO., Ltd., and REED, M. May 2, 1938, No. 13046. [Class 40 (iv)] In a multiplex system in which speech modulates a carrier frequency which is the same for all channels and one of the side-bands then modulates a carrier characteristic of the channel, the lower side-band being selected for transmission, corresponding demodulating arrangements being provided for reception, the second modulator of each channel acts as a frequency reducer and the first demodulator acts as a frequency raiser. The common carrier frequency supplied to the first modulators and second demodulators is greater than the highest transmitted frequency, and preferably greater than twice that frequency in order to avoid interaction between channels at the first demodulation stage. In the Figure, which shows the arrangements for two out of a number of channels, the first modulators FMA, FMR and second demodulators SDA, SDR are supplied with a carrier frequency p, while the second modulators SMA, SMR and first demodulators FDA, FDR are supplied with progressively increasing carrier frequencies such as p+s1, p+sr. For convenience in generating these frequencies, they may be all harmonics of a basic frequency w, which has a value slightly greater than the width of the speech band in order to secure proper separation of the channels. Crystal or other band-pass filters EBPA, EBPR, WBPA, WBPB are inserted between the modulators and demodulators to select the lower side-band, and the channels are coupled to the, transmission path through low-pass filters ELP. WLP having a cut-off frequency sn+w. Each of the filters ELP, WLP may be replaced by a number of band-pass filters each individual to a channel or to a small number of channels.
