Title: Improvements in or relating to apparatus for combining signals
Inventor: BENNETT ARTHUR JAMES
IPC: H03H7/46
Filed: 1965-11-19
Abstract: 1,122,742. Multiplex radio signalling. PYE Ltd. 19 Nov., 1965 [19 Nov., 1964], No. 49217/65. Heading H4L. [Also in Division H1] A circulator is used to combine two signals having different radio frequencies. In the example shown, the sound-modulated carrier of a television signal is applied to port 2 of a three-port circulator 1 which passes the signal to port 4. A rejection circuit for the sound signal is inserted in the coaxial lead 5 of the port 4. This consists of a length of coaxial line 7 having a characteristic impedance less than that of the line 5 and of such a length (less than #/4) that it exhibits an inductive reactance, the inductance being tuned to series resonance by a capacitor 6. A further capacitor 9 tunes the combination 6, 7 to parallel resonance at the frequency of a visioncarrier signal from source 8, whereby this signal, together with the reflected soundcarrier, is transmitted to the port 4. Both signals are passed by the circulator 1 to port 10 and hence, by a further circulator 12, to load 11. Reflections from load 11 are passed by the circulator 12 to a dissipative load 16. In a modification, the two three-port circulators 1, 12 are replaced by a single four-port circulator 17 (Fig. 5, not shown).

Bolts 24 which are threaded into annular element 27 serve to hold it fixed relative to rotor 21 against sleeves 25, the sleeves also serving as bearing surfaces for the pivoted blades 24. Additional support is provided by the annular element being bolted to the rotor at positions along its circumference midway between each blade. A frusto-conical ring 30 is held in position between the lower surface of the rotor 21 and a groove 28 on the inner edge 27A of annular element 27 and acts to deflect outwardly any material which has passed behind the blades. The rotor is driven via a vertical shaft 1 which is fixed to, and concentric with a drum 2 whilst one or more vertical ribs 19, mounted rotatably on the drum serve as deflectors for the cut crop. A dish shaped ground engaging member 36 supports the cutter and minimises the accumulation of foreign material in the space beneath the rotor. The ring 30 may be replaced by a plurality of struts, each of which is welded at one end to the underside of rotor 21 and at the other end to the inner edge of annular element 27, making it unnecessary for the latter to be threaded to the bolts 24. In an alternative embodiment, the annular element takes the form of a tubular ring of circular cross-section.

Abstract: 1,194,358. Valves for surgical use. D. C. MEARS. 22 Nov., 1967, No. 53123/67. Heading A5R. [Also in Division F2] A valve, which is adapted for use in industry or as a medical appliance, namely for the purpose of urinary bladder control, and which permits the insertion therethrough of cystoscopes, fibre glass viewing tubes and other instruments, comprises an annular housing 1 having disposed within it a fixed plate 2 and a movable plate 3, each plate having embedded therein a permanent magnet 4, 5 respectively, which extends diametrically across it, and having a semi-circular aperture formed to one side of the respective magnet. Relative rotation of the plates, for example to effect closure of the valve by moving the aperture of plate 3 out of alignment with that of plate 2, is achieved by suitable manipulation of a permanent magnet disposed outside the valve, the nature of the manipulation determining whether simple relative rotation between the plates is effected or whether plate 3 is firstly moved longitudinally out of contact with plate 2 and is then rotated relative to plate 3. Removal of the external magnetic field results in the plates returning to the position shown by virtue of the interaction of the two magnets 4 and 5. Moreover, when the valve is in its closed position, it can be opened by longitudinal displacement of plate 3 relative to plate 2, upon the force of pressure at the inlet exceeding the force of attraction of the two magnets 4 and 5. The component parts of the valve can be made from polytetrafluorethylene, polypropylene, polycarbonate, high density polyethylen, ceramics, pure titanium, titanium alloys or cobolt-chromium surgical alloys and the housing exterior can ,be given a covering which permits tissue encapsulation. The magnets are made of ferrous or cobaltplatinum alloy and are sealed in position, by P.T.F.E. plugs (4a, 5a, Figs. 4 and 6, not shown). In alternative embodiment the external controlling magnetic field may be derived from an electromagnet. Furthermore, the valve may have more than one inlet and outlet, as well as more than one movable plate.

The target device 2 has an electrical sensor sensitive to said radiation and may be a resistor 10 which is connected to the electrical radiation emitting means by an electrical lead 16, via control means. The gun is provided with a switch 6, a trigger 7 for actuating the switch 6, via a hammer 9, and a socket 8 for the electrical lead 16. The target 2 has an opening 11 in alignment with the resistor 10, a switch 13, a thyristor 14, a socket 15 for the lead 16, and contains a battery therein. In use the operating of the trigger 7 closes the switch 13 and light emits from the gun. When a hit is made the light passes through the opening 11 of the target 2 and on to the resistor 10, thus causing the thyristor 14 to apply a shunt across the battery 12 and lower the light intensity. Alternatively, the light may be switched off. The thyristor can be re-set, the beam having been removed from the resistor 10, by opening the switch 13. A combat game is played by two persons, each carrying a target device and a gun. A pulse of light radiation may be obtained by the momentary closing of the switch 13, using mechanical means, or the pulse may be produced by electronic means. The electric light bulb may be replaced by a flash unit.
