Title: Apparatus for sensing signal tape records
IPC: H04L17/14
Filed: 1951-10-09
Abstract: 689,763. Photo-electric record sensing apparatus. TELETYPE CORPORATION. Oct. 9, 1951 [Oct. 14, 1950], No. 23465/51. Class 40 (iii). In sensing a record tape on which information is impressed in the form of lidded apertures the apertures are opened to allow light to pass through them for photo-electric sensing. In a first embodiment (Fig. 1) the tape 10 passes over nozzles 26 from each of which issues a jet of air supplied by a fan or air compressor 23. These jets lift the lids of the apertures and light from a source 18 is then passed through each aperture to a photo-cell 20 associated with that aperture. A light conductive rod 19 is provided between each cell and its aperture. In the embodiment of Fig. 4, the strip is caused to bend over a light conducting rod 53 at the end of which is situated a light source 18. The bending causes the apertures to open and light passes through to photo-cells 20 situated above the strip. A rod 54 closes the apertures and enables the strip to be returned to its original path. The embodiment of Fig. 3 (not shown) differs only in that the light source is situated above the strip; the light passes through the aperture and the light rod around which the strip is bent to a row of cells below. In the embodiment of Fig. 5 (not shown), the strip bends over a narrow opaque rod so that light is able to pass through the aperture behind the rod and to the associated light cell, a light guide being provided for each cell. The strip is advanced a step at a time by an electromagnetically-operated ratchet-and-pawl mechanism operated by a cam-closed contact, this cam being driven in synchronism with a distributer arm which transmits the output of each photo-cell in turn for one row of apertures, the cam then moving the next row on the strip to the sensing position.

Title: Improvements in or relating to radio-frequency oscillation generators
IPC: G01S7/28
Filed: 1945-09-13
Abstract: 599,114. Radiolocation. SOLLEY, A. E. Sept. 13, 1945, No. 23690. [Class 40 (v)] A radar system which employs the Doppler effect to distinguish between moving and stationary targets, incorporates a mechanical vibrator C responsive to excitation by electrical oscillations, e.g. a piezo-electric crystal, and a mechanical delay line DL, so as to derive a series of contiguous pulses, each comprising a carrier wave oscillation bearing a fixed phase relationship to the inititating oscillation. Pulses received direct from the transmitter are converted into mechanical oscillations and passed down the delay line, the ends of which are mismatched so that a succession of reflected pulses is produced. The length of the delay line is such that each successive pulse is delayed from the previous one by the pulse width so that when the reflected pulses are reconverted into electrical oscillations by the device C, a substantially continuous electrical oscillation is produced which is used as the reference frequency for the production of Doppler beat frequencies. In the system illustrated, the pulses received direct from the transmitter T are mixed with the output of a local oscillator 02 in mixer M2, the intermediate frequency oscillation produced then being converted to a mechanical oscillation in the piezo-electric vibrator C and applied to the delay line DL which may be of the type described in Specification 593,539. The reflected pulses are converted into a substantially continuous electrical oscillation the frequency of which is changed by the mixer M2 to the original transmitted frequency. This signal is mixed with the incoming echo signals, these being applied together to the radar receiver comprising radio frequency stages R, mixer M1, local oscillator O1 intermediate frequency amplifier A and second detector D at the output of which echo pulses from moving objects will bear an amplitude modulation due to the Doppler effect. In an alternative embodiment, Fig. 3 (not shown), the intermediate frequency output from the mixer M1 is converted directly into mechanical oscillations and used to produce the continuous reference oscillation which is thus injected into the intermediate frequency stages of the receiver.

Abstract: 788,097. Transporting solids in a liquid stream. COAL INDUSTRY (PATENTS), Ltd. Nov. 26, 1954 [Aug. 27, 1953], No. 23702/53. Class 102(2). [Also in Group XXXV] In a system for transporting coal in a stream of water, the speed of the water pump is automatically varied to maintain the concentration of coal in the stream constant, and if the pump reaches maximum output the coal input is reduced to prevent choking. The coal is carried from a feeder 19, Fig. 1, to a separator 13 along a duct 10 by water circulated by an electric pump 17. The concentration of coal is detected at 32 by comparing the rate of flow in the duct with the pressure in the duct. An equation for the relationship between the three factors is given. The rate of flow is measured, Fig. 2 (not shown) by a differential diaphragm responsive to the pressure change across a venturi tube included in a vertical section of the duct 10, the diaphragm actuating the slider of a rheostat and the pressure in the duct is similarly detected. The two rheostats control the speeds of a pair of motors which adjust a cam which actuates a rheostat providing an output signal corresponding to the concentration. This signal is applied to an undisclosed device 28 which controls the speed of the electric pump 17. The output of the pump is detected by its motor current and when this reaches a predetermined maximum a signal is sent by undisclosed apparatus to an undisclosed unit 23 which reduces the speed of the motor 20 driving the coal feeder.
