Abstract: 1486808 Radio receiving circuits; tone control of amplifiers SONY CORP 27 Nov 1974 [30 Nov 1973] 51419/74 Heading H3T In a radio receiver a diode detector provides the demodulated signal and also signals for controlling in accordance with the received signal level the gain of frequency changes and IF stages and the pass band of a filter located between the detector and audio preamplifier. In Fig. 3 the level of the higher audio frequencies is reduced as the signal level falls by using a control signal derived from detector D to render conducting a transistor Q5 connected in series with a filter capacitor 17. (In Fig. 1, not shown, Q5 is also connected in series with the shunt capacitor of a further filter stage.) Another transistor Q6 controls an FET Q8 to simultaneously reduce the low frequency response and a transistor Q7 increases the gain of the preamplifier stage Q4 to provide volume compensation. In Fig. 4 (not shown) a variable capacitor diode is also connected between its crystal IF filters to narrow the bandwidth for low level signals to remove interfering signals.

Title: Mode interferometer squinting radar antenna
IPC: H01Q3/26
Filed: 1972-11-08
Abstract: 1362926 Aerials UNITED AIRCRAFT CORP 8 Nov 1972 [21 Jan 1972] 51528/72 Heading H4A Apparatus for coupling electromagnetic waves between waveguides and a reflector comprises a first section of a pair of waveguides having means for providing a variable relative phase shift between waves therein, a second section of a pair of waveguides having means for providing a relative phase shift between waves therein. All the waveguides have the same primary dimensions and the two sections are coupled together by, for example, a short slot coupler. A fifth waveguide having a primary dimension which is substantially twice that of the corresponding primary dimension of the other waveguides is connected at one end to the said second section, and has a radiating aperture at its other end. As described, electromagnetic waves enter a complex waveguide assembly 21, Fig. 8, through openings 33, 34 and propagate along a section A in two separate similar waveguides, i.e., of rectangular cross-section, supporting the TE 10  mode. The waveguides continue into a section B, where a variable phase shifter 44 is disposed. This comprises a ferrite section 46 with electrical winding 48, and with matching sections 50, 52 at its ends. The current in the winding 48 is determined by a squint control circuit 54, which may be manually operated or may be automatically operated by a beam steering computer. In a further section C a short slot coupler is provided, such that half of the wave energy in each waveguide spills into the other, with a 90 degree phase lag. The waves continue along a section D in separate waveguides in one of which is a second phase shifter 61 with a winding 62 carrying a current from a source 64, which provides a constant phase shift of 90 degrees. The last section E is a single waveguide, having twice the width of the other waveguide sections, within which the two TE 10  mode waves from the section D combine to produce single TE 10  and TE 20  mode waves across the entire width of the section E (Figs. 1 to 4, not shown). A tuning screw 68 is provided to further the development of the TE 10  mode the section E. The phase centre of the resultant waves emanating from the open end 63 of the section E may be moved transversely by adjustment of the squint control circuit 54, thus providing scanning when the assembly is used as a feed for a parabolic reflector (Figs. 5 to 7, not shown).

The top edge of one 1a of the narrow sides is lower than the top edges of the other sides to provide a belt outlet opening 8. The magazine further comprises a sliding lid 2 having one end 2a bent downwardly, the other end 2c of the lid being optionally introducable from either narrow side of the case 1. In one of its positions the bent end 2a of the lid 2 rests tightly against the lower top edge of the narrow side 1a to close the belt outlet opening. The case 1 and lid 2 are provided with indentations 11, 10 for strengthening purposes. The upper ends of the major sides of the case 1 are provided with stamped patterns to facilitate the handling of the magazine. Guide grooves 14 for the lid pass through the stamped patterns.

Abstract: 1,180,455. Vehicle manoeuvering devices. ANDRE CITROEN S.A. 17 Nov., 1967 [16 Dec., 1966], No. 52512/67 Heading B7D. A vehicle manoeuvering device, for use with a vehicle equipped with an hydraulic pressure fluid distribution system i.e. a hydropneumatic suspension system, comprises a piston and cylinder 21, 1 which is stored in the vehicle boot, the piston having at its free end a wheel 22 such that when the piston is extended the rear end of the vehicle is raised from the ground and is supported by the wheel, the piston and cylinder being operated from a manual lever 7 which controls a fluid supply valve 4 and the wheel 24. being rotatable to move the rear end of the vehicle in either lateral direction by a reversible electric motor 25 driving through reduction gearing 26. A lock associated with valve 4 only allows the rear end of the vehicle to be raised when the front road wheels AV are stationary, thereby closing contact 12, and when the gear lever 14 is in neutral, thereby closing contact 13. A look 15 holds the gear lever in its neutral position until the piston is completely withdrawn in its cylinder thereby breaking contacts 18, 19. The motor 25 is operated by a manual lever 28 having three positions and the motor will only operate when the hand and foot brakes 36, 37 are in their off positions thereby closing contacts 34, 35. A contact 33 indicating that the rear road wheels are free of the ground must also be closed. A probe 31 cuts off motor 25 when the vehicle is in close proximity to the kerb 38. Piston 21 may alternatively be pneumatically or electrically controlled and motor 25 alternatively replaced by a pneumatic or hydraulic motor.
