Filed: 1976-01-21
Abstract: 1533426 Radio obstacle detection LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 21 Jan 1976 [29 Jan 1975] 02377/76 Heading H4D With a Doppler effect obstacle detector mounted at the front of a vehicle, it is difficult, with r.f. frequencies and aerial dimensions in use, to confine detected 'obstacles' to those actually lying in the path of the vehicle. To effectively narrow the angular zone of detection, an inhibiting radar/direction finder is added, wherein microwave radiation is alternately radiated from small angularly offset printed circuit aerials 13, 14, Fig. 2, in respective beams 3 and 4, Fig. 1, which overlap in an angular region 6 lying along the axis of the vehicle. Echoes from an 'obstacle' are detected using a third small printed circuit aerial 20 with a reception lobe 5. With the line to the 'obstacle' outside the region 6, e.g. at P2, the detector (21) output is as S2, Fig. 3, i.e. no echoes due to radiation from beam 4. With the 'obstacle' at P3 however the output S3 at no time falls to zero. After removal of the D.C. component by capacitor C a threshold detector 22 produces an output from signal S3, which signal is used to enable the utilization of detection signals from the Doppler effect obstacle detector.

Title: Apparatus for cleaning, filling and sealing containers
IPC: B08B9/28
Filed: 1960-01-22
Abstract: Apparatus for cleaning, filling and sealing containers of glass, metal or plastics, particularly ampoules (see Division B8), comprises a drum 11 intermittently rotated by motor 8 and formed on its curved surface with guideways 12 for receiving magazines 14 of ampoules, the drum being enclosed in a housing 15. As the drum rotates, the magazines are moved successively past a number of cleaning and filling stations, and finally arrive at a sealing station 31 before being ejected from the housing. At the sealing station, there is provided for each ampoule in the magazine a burner 73 and a pair of gripper arms 63, 65, the former comprising a rod grooved to receive the ampoule stem, and the latter comprising a wire bent through approximately 90 degrees as its lower end. The members 63 are mounted on shafts 68, 70, whilst those 65 are mounted on shafts 67, 69, the four shafts being carried by a lever 76 which is pivotable about 74 by means of a Bowden cable 77. The burners are mounted on a separate lever 75, also pivotable about 74, and arranged to engage with a stop 78 provided on lever 76, so that the two levers 75, 76 move in synchronization. After the drum 11 has rotated to feed a fresh batch of ampoules to the sealing station, the Bowden cable 77 operates automatically to lower the gripper arms and burners into proximity with the ampoules, the gripper arms simultaneously depressing the cover-plate 57 of the magazine against the action of springs 58 to expose the ampoule stems, and a Bowden cable 66a operates to rotate shaft 67, which rotation is transmitted to shafts 68, 69, 70 via gearing, with the result that the gripper arms close upon the ampoule stems. After the stems have been heated to a plastic condition, the gripper arms are automatically raised to extrude and seal the stems, the stop 78 then becoming operative to raise the burners. Continued raising of the gripper arms then breaks the tops of the stems, the latter being released upon opening the grippers <PICT:0946220/C1/1> <PICT:0946220/C1/2> to fall via a shoot 79 into a container 80 (Fig. 1).

Title: Improvements in or relating to cartridge magazines for small arms
IPC: F41A9/70
Filed: 1931-01-27
Abstract: 363,869. Smallarm magazines. FROMMER, R. VON, 158, Soroksari Ut, Budapest. Jan. 27, 1931, No. 2640. [Class 119.] A cartridge magazine of the kind containing two vertical rows of cartridges is provided with two manually movable lips which are normally separated by a distance greater than the largest diameter of a cartridge. By this arrangement the cartridges may be inserted into the magazine without moving the lips, but by retracting the lips the cartridges will be ejected by the magazine spring and the magazine emptied. According to one construction, the lips 6, Figs. 2 and 4, are formed on levers 7 which are pivotally mounted, scissorswise, on a pin 8. The lips are normally in position to retain the cartridges 5 within the magazine 1 by a spring 9. The lower ends of the levers are separated to open the lips by the wedge-shaped nose 11 of a pushbutton 10. In a modification, the lower end of each lever is to the same side of the pin 8 vertically as the lip which it operates. In this case, the lower ends of the levers are moved together to separate the lips by a V-shaped slot in the pushbutton. In another modification, Fig. 11, the levers are arranged on separate pins 12 and have arms 15 which engage the wedge-shaped ends 17 of a vertically moving slide 16. The slide is moved by the arm 19 of a two-armed pivoted lever, the other arm of which carries the pushbutton. In another arrangement, the slide may be dispensed with and the lower ends of the levers are formed with pushbuttons which protrude through lateral openings in the gun. In a further modification, the ends 17 of the slide engage the lateral surfaces of the arms 15 so that a downward movement of the slide effects the opening of the lips. In a still further modification, Figs. 15 and 17, the levers are moved by the wedge-shaped ends 17 of a horizontal slide 16. Extensions 26 on the slide are formed with upturned portions 25 which normally engage with the lower ends of the levers to, prevent them from moving. Disengagement of this locking means is effected when the slide is moved. In another modification, the extensions 26 are dispensed with.

Title: Improvements in wedge acting brake or clutch
IPC: F16D17/00
Filed: 1922-01-30
Abstract: 196,987. Cole, W. H. Jan. 30, 1922. Clutches, friction.-Two or more wedge-shaped blocks are adapted to be forced between two cylindrical surfaces, eccentrically disposed with respect to each other, one having a limited rotational movement with respect to its shaft, the coupling mechanism by which the blocks are actuated being such that the blocks react on each other to equalize their action and to prevent jamming. As shown, the pair of blocks C are forced between the cylindrical surfaces or drums A, B by a cam and links D actuated by a lever G. The drum B may be the driven member and a limited floating movement is permitted thereto by the pin and slot H, I. By this movement and also by the fact that the frictional drag on the one block tends to withdraw the other block through the coupling D, the action of the blocks is equalized and jamming thereof is prevented. The blocks may be guided by pins and slots or by tension springs connected to the blocks. Specification 139,899 is referred to.

Abstract: 549,769. Wireless receiving apparatus. WHITE, S. Y. Feb. 28, 1941, No. 2754. Convention date, Feb. 29, 1940. [Class 40 (v)] A radio receiving system having a circuit tunable by a variable reactance employing a thermionic valve, is characterized in that for automatically and continuously tuning said circuit over a range of frequencies including a plurality of adjacent communication channels'said variable. reactance device is operated by potential' variations of a low frequency, a director device being arranged to render ineffective said potential variations in response to the reception of a carrier in one of said channels. Fig. 2 shows the invention applied to a superheterodyne receiver in which a part of the output from the I:F. amplifier is fed by lead 14 to a valve VT1 in the output of which are circuits TC1, TC2 tuned to frequencies on either side of the intermediate frequency so that the differential voltage from load resistors R1, R2 of diodes VT2 indicates both by sign and amplitude, departures from tuning. This voltage is fed by lead 11 to the grid of a valve VT4 arranged as a reactance in the circuit of a beat oscillator VT3 supplying. the mixer 3. and varies the oscillator frequency to correct departures from tuning. A low frequency scanning oscillator VT5, VT6 preferably of saw-tooth kind, also supplies to lead 11 a voltage which continuously sweeps the oscillator frequency over about 1 per cent of its range to facilitate finding a station. The scanning oscillator voltage is however small and is entirely swamped by the voltage from VT2 on receipt of a signal, and so the tuning remains fixed. On stoppage of the received carrier, however, the scanning is resumed. If desired, the scanning oscillator may be omitted, and a kind of random scanning. is performed by the variable noise component voltages from VT2. Specification 541,393 is referred to.
