Abstract: 1339148 Radiography RAYTHEON CO 29 Sept 1971 [2 Oct 1970] 45431/71 Heading H4D [Also in Division G2] Distribution of particle radiation, e.g. from a tracer fed thyroid gland 21, Fig. 1, is given a spatial coding, e.g. by a mask 30, Fig. 3, having a rectangular matrix of holes decreasing in sizes by rows and columns from the top left hand corner such that radiation from a single point source is detected (via scintillator 36, by an array of detectors 40, similar to those in the "Anger" camera) as a two dimensional array of varying intensity sources, horizontal or vertical scanning of which gives a frequency sliding signal, which when processed in a manner similar to that of "chirp" returns in pulse compression radar, produces a single point source indication with high resolution. In the arrangement of Fig. 2, the detectors' outputs are displayed in a first storage tube and the display horizontally scanned. The resulting "chirp" pulse trains are compressed in an electro acoustic dispersive delay line 62, Fig. 5, 6 (not shown) to give a display at second storage tube 90 resolved in the horizontal direction. The procedure is repeated for a vertical scan to give a fully resolved display at. 28. The array of detectors 40 and storage tube 52 can be replaced by a film on which the two dimensional array of sources is developed Fig. 7 (not shown). The resulting picture then being horizontally and then vertically scanned as before. The spatial coding of radiation may alternatively be produced by a two dimension array of discrete radiation sources Fig. 9, varying in size in the same manner as the holes in the mask.  With such a source 152, Fig. 10, producing X- rays and using a film 154 to carry the visible image of the two dimensioned spatially coded X-ray picture of object 158, the image can be optically decoded (analysed) by a spatial filter system 166 comprising lenses 168, 170, spatial filter 172 and screen 174. The two dimensional mask 30 can be replaced by one having a single column of changing size holes Fig. 11 (not shown) the vertically held mask being mechanically scanned horizontally in front of the object 34 to produce the horizontal dimension.

Title: Improvements in or relating to work study recording systems

IPC: A45C5/02
Filed: 1967-10-07
Abstract: 1,147,503. Work study analysis. ROLLSROYCE Ltd. 7 Oct., 1967, No. 45982/67. Heading G4D. Apparatus for compiling a work study analysis comprising a tape recorder and a playback system for printing coded information. The analyst can record spoken information through a microphone 56 and circuit 58 which filters out frequencies of 5 kc/s. Having estimated the time for part of a process he closes one of a set of switches A1, B1, C1 ... associated with a counter 42 and momentarily operates a push-button 14. A 10c/s. oscillator 18 then delivers bursts of 5 kc/s. pulses from an oscillator 55 to a tape recorder input 60 until the counter 42 has counted up to the selected switch. The accumulated recordings are played back through a filter 65, Fig. 2, which passes 5 kc/s. pulses. Each sequence of bursts of pulses passes at 69 to a rate counter. The first burst enables a circuit 62 after a delay long enough for the rate counter to complete its operation. This circuit includes a clock pulse generator 76 which continuously cycles a decimal counter 79 to operate a timing counter via 107. The first time the counter cycles after the rate counter has been operated an amplifier 105 is energized to print from the rate counter and the timing counter. Immediately afterwards an amplifier 106 energizes to reset the rate and timing counters.

Abstract: 1442373 Control of A.C. motors DANFOSS AS 4 Oct 1973 [4 Oct 1972] 46389/73 Heading H2J A single phase asynchronous motor 1 having main and starting windings 2, 3 is controlled by a starting device comprising thermal switches 7, 9 and a resistor 8, each switch being of the type responsive to either the current flowing through it when closed or the glow discharge across it when open, switch 7 being normally-closed, switch 9 normally-open and the value of resistor 8 being chosen so that during starting the following sequence of operations occur: (1) Closure of main switch 4 causes a low current to pass through members 3, 7, 8. (2) The resultant glow discharge produced by resistor 8 across switch 9 causes it to close after a time delay T 1  and produce full starting current through the winding 3. (3) This full current causes a bimetal element 10 to open switch 7 after a tune delay T 2  to reduce the current to another low value (dependent on the glow discharge ecross switch 7). (4) Switch 9, which has been kept closed by a bimetal 11 during the passage of full current, opens after a time delay following the opening of switch 7, thus further reducing the current and terminating the starting action, since the resultant voltage across resistor 8 is insufficient to produce further glow discharge across and closure of switch 9, and the switch 7 is maintained open by its glow discharge until the switch 4 is opened to de-energize the motor. Typical characteristics are discussed relating the voltage, current and condition of members 3, 7, 8 and 9 to time, Fig. 2 (not shown), and comparison is made with the starting device described in Specification 1,086,968.

During playback the head 8 picks up signals from track 14, but these are of low frequency (60, 240 or 480 cycles/second when recorded by head 13 and about 7 kc./s. when played back by head 8) and are eliminated by passing the signals through an amplifier or filter which cuts out frequencies below about 200 kc./s. Local circuits.-Signals from head 5 pass to an amplifier 24, Fig. 6, and signals from head 8 pass to an amplifier 25 which is similar except that some component values are altered to give a low-frequency cut-off. Amplifier 24 may cover the range 200 kc./s. to 6 mc./s. and amplifier 25 the range 500 kc./s. to 6 mc./s. A gain control 47<SP>1</SP> and an attenuator 56 may be provided to reduce the amplitude of the output from amplifier 25 to between one half and one fifth of that from amplifier 24; this reduces noies during the periods when the signals overlap. The outputs of the two amplifiers pass to a mixer 26 and a frequency demodulator 27. Specifications 959,623 and 990,534 are referred to.
