Abstract: 413,724. Valve circuits for wireless reception. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, McAINSH, N. J., and SHARP, S., c/o General Electric Co., Stoke, Coventry. Jan. 16, 1933, No. 1401. [Class 40 (v).] In a superheterodyne receiver, the circuit L2, C2 in which the local oscillations are generated is inductively coupled both to an inductance L3, connected between the cathode of the detector valve and one end of the tuned input circuit L1, C1, and to an inductance L4 connected in series with a condenser C4 across the circuit L1, C1. The impedance of the inductance L3 is small compared with the grid-cathode impedance C3 of the valve. A resistance may be connected in series, or parallel with the condenser C4 to adjust the power factor of the circuit L4, C4. The values of L3, C3, L4, C4 are so chosen that these form a balanced-bridge, the input circuit, L1, C2 constituting a diagonal of the bridge thus preventing radiation of the local oscillations. Reference has been directed by the Comptroller to U.S.A. Specification 1,820,809.

A device for drawing parallel lines or hatching comprises a set-square 1 with a slot 3 therein parallel to the hypothenuse 2, a strip member 4 longitudinally slidable in the slot and biased towards one end by a spring 5 having at least one inclined ramp 4b and a depressible member carrying at least one roller 8 for engagement with the ramp on depressing the depressible member 7 to press the strip 4 into non-sliding contact with the surface being ruled and at the same time relieve the pressure on the set-square 1 to allow movement thereof relative to the strip member against the spring bias while the roller 8 moves down the ramp, release of the depressible member permitting the strip member 4 to return to its original position in the slot 3 under the action of the spring 5 in readiness for a further operation. As shown, the depressible member is in the form of a resilient bridge 7 longitudinally spanning the slot 3 and carries a pair of rollers 8 arranged on depression of the bridge to contact the two ramps 4b. In an alternative construction the depressible member may be a lever pivoted at one end to the set-square and carrying between its ends a roller for engagement with a ramp on the slide 4. An adjustable stop member 11, Fig. 1, is pivoted at 12 to the set-square 1 and is adapted to co-operate with an edge 10 formed on the strip member 4 at an angle to the longitudinal axis thereof, so as to limit the extent of movement of the strip 4 in the slot 3. The stop may be locked in position by a clamping screw 14 mounted on a block 15. The first Provisional Specification describes a modification in which the end of the slot is constructed as an adjustable stop comprising a wedgeshaped member with a wedge-side forming the end of the slot and co-operating with a guide so as to be slidable with the wedge side movable transversely of the slot. The roller or wheel is mounted on a vertical plunger suitably mounted in the bridge member, pressure being applied to the plunger through a pivotally mounted trigger member. The second Provisional Specification describes a modification in which one edge of the strip is recessed over a portion of its length and the adjacent edge of the slot carries projections which lie within the recessed portion and constitute stops for limiting the travel of the strip relative to the set-square. The recess of the strip member is formed at each of its ends with an inclined portion which when abutted by the corresponding stop projection causes the non-recessed edge of the strip member to be pressed against its adjacent longitudinal edge of the slot.
