Filed: 1964-10-05
Abstract: 1,120,112. Microphones. STANDARD TELEPHONES & CABLES Ltd. 1 Oct., 1965 [5 Oct., 1964], No. 40408/64. Heading H4J. In apparatus for filling the carbon chambers of carbon granule transmitters, a transmitter 15 (Fig. 1), is mounted on a flexible strip 11 with its major axis vertical. The drive 14 of a vibration generator 13 is connected to the strip 11 to vibrate the transmitter 15 in a vertical direction. Carbon granules 18 are fed from a bottle 17 to an opening in the carbon chamber by free fall while the transmitter 15 is vibrating vertically. The bottle 17 is connected by flexible tubing 19 to a nozzle 20 having a rotary tap 21 over the transmitter filling hole. A recess for mounting the transmitter 15 is provided in a platform 10 which also carries a spring clip 22 for clamping the nozzle 20. After filling the carbon chamber, settlement of the carbon is assisted by lightly tapping the transmitter 15 with the gong hammer of a telephone set ringer. In an alternative apparatus (Figs. 2, 3, not shown), a platform (35) has a recess which extends forwards so that a transmitter may be slid into position from the front of the apparatus. The transmitter is clamped in position by a compression spring (43) surrounding a rigid tube (39) and pressing on to a hollow cylindrical member (42). A key (45) in a channel of an upper bridge-piece (38) connects with the tube (39) and can be moved to lift the tube (39) and member (42) to permit a transmitter to be inserted, after which the key (45) can be moved down and looked to clamp the transmitter. The lower ends of the tube (39) and member (42) mate with the transmitter. A rotary tap (47) in the tube (39) extends through a hole in the member (42). The tap (47) has an arm (48) to which a cable (49) is attached. Two solenoids (50, 51) can move the cable (49) to open and close the tap (47). A second vibrator (55) comprising a modified uniselector, when switched on, imparts a horizontal vibration to the transmitter. In operation, an empty transmitter is slid in and clamped to the platform (35). Vibrator (31) is switched on. Tap (47) is opened and subsequently closed by the solenoids (50, 51). Vibrator (31) is then switched off and the vibrator (55) is switched on for the required time. The transmitter is finally unclamped and removed. The switching operations may be automatically controlled by a motor associated with cams which successively operate microswitches.

Abstract: 1,199,201. Magnetic data stores; trackchanging. POTTER INSTRUMENT CO. Inc. 5 Sept., 1967 [23 Sept., 1966], No. 40438/67. Heading G5R. [Also in Division H3] A magnetic storage system employing a plurality of magnetic transducers movable to different tracks selected by an address register includes means to produce a signal upon receipt of an address to indicate whether transducer movement to the addressed track is necessary. The signal is used to enable transducing immediately if no movement is necessary, or to disable the transducer until movement is complete. As described, a bar (13, Fig. 1, not shown) carrying transducers co-operable with endless tapes (11) is moved by a whiffle tree linkage (19) operated by five rotary solenoids (15) to give 32 possible positions. The register 21 selects the appropriate transducer and energizes the appropriate driving circuits 23 to position the head bar (13). Each circuit 23 provides a signal to OR-gate 25 if its solenoid is actuated according to the address, and the gated output is fed to AND-gate 27 enabled by a strobe pulse a few microseconds after receipt of the address. The output from gate 27 is sensed by stop circuit 31 to disable the transducers 24 if movement is imminent and enables them once the transducer bar (13) is properly positioned, the latter being determined by the circuit 31 and by contacts on the solenoid armatures. A monostable 27 controls the circuits 23 and the controlling circuits 23, 31 employ semiconductor circuits (Figs. 3-5, not shown, see Division H3).

Abstract: 1,115,171. Measuring aircraft height electrically. RIPPER ROBOTS Ltd. Jan. 4, 1966 [Oct. 5, 1964], No. 40600/64. Heading G1N. A feeler gauge for measuring the height of a low-flying aircraft above the terrain comprises a spring-loaded arm 10 (Fig. 1) attached to a skid 15, the limiting positions of the arm being sensed by switches 20, 22, and intermediate positions by a potentiometer 21. The skid 15 is pivoted to the arm 10 at 17, and the arm 10 is pivoted to the aircraft body 11 at 12, the first axes being transverse to the direction of travel F. The skid and arm are spring-biased. The lower end of the skid may be fitted with a wheel or float. When the aircraft is too high, the skid 15 is in its extreme clockwise position, closing switch 20 and lighting a first warning lamp. When the lower end of skid 15 trails on the terrain it is displaced anti-clockwise about pivot 17, carrying with it the slider of a potentiometer 21, which thus gives a height signal. Excessive displacement of skid 15 is transmitted through a stop to the arm 10 and closes switch 22, lighting a second warning lamp. The signals may be used for automatic control of the aircraft. In modifications, the potentiometer may be fitted to pivot 12 instead of pivot 17, and the position of pivot 12 may be manually or automatically adjusted in accordance with the pitch of the aircraft. The assembly may be supported on a vertical shaft associated with a horizontal ring potentiometer to give an indication of lateral drift of the aircraft.

Abstract: 1426005 Dual wavelength photometers BAXTER LABORATORIES Inc 5 Sept 1973 [21 Sept 1972] 41725/73 Heading G1A Absorption analysis of a component of a sample is effected by passing two adjacent wavelengths of light through the sample in sequence to a common detector, one wavelength being such that it is absorbed by the component investigated and the other wavelength being largely unaffected by the component. The wavelengths are close enough to be equally absorbed or scattered by the other components of the sample, so that the difference of their absorption represents the component under test. Fig. 3 shows the invention applied to measuring the oxygenation characteristics of blood. The blood is placed in a titration cuvette 11 where it is titrated with H 2 O 2  while it is analyzed by light passing from source 19 to photo-multiplier 22. A filter disc 23 carries filters to select the two adjacent wavelengths, which for blood may be 439 nm and 448 nm. The photo-multiplier output is gated by transistors 32, 33 &c. to a log amplifier 31, and the output of this is gated into track and hold circuits 36, 37 &c. The difference of the outputs of pairs of the track and hold circuits is found at amplifiers 38 to form the final output indicative of the oxygenation. The filter disc has six filters arranged in three pairs, an apertured disc 51 serving to provide, with source 52, diode 53 and monostables D-M, synchronizing gating pulses so that each amplifier 38 has an output representing the difference between the absorption for a respective pair of filters. If it is desired, a manually operated multipole switch can be provided to allow the use of only two track and hold circuits and only one amplifier 38. Before use the response of the system at the two different wavelengths is made equal by attenuators such as 41; a partially transmitting screen carried by a disc 6 associated with the filter disc can be moved to a position where one of each pair of filters has its path obstructed a known amount by the screen Figs. 8, 11, 12 (not shown) and the attenuators 39 connected to amplifiers 38 are set so that the output meter 40 gives the correct reading for this known attenuation. The high voltage supply for the photo-multiplier is automatically adjusted during use to keep its sensitivity constant.
