Title: Ultrasonic impulse apparatus comprising transmitting and receiving components for measuring small impulse travel times
IPC: G01N29/34
Filed: 1955-04-14
Abstract: 796,600. Ultrasonic gauging. SIEMENSREINIGER-WERKE AKT.-GES. April 14. 1955 [April 14, 1954], No. 10816/55. Class 118(2). Ultrasonic impulse apparatus for the measurement of small impulse travel times by the impulse echo technique, particularly for determining the thickness of workpieces smaller than half the spatial length of an impulse, comprises a transmitter, a receiver, a transducer and an indicator with means disposed between the transducer and the indicator for varying the means frequency of the frequency spectrum to be utilized, whereby multiple echo impulses may be separated to appear on a cathode-ray tube as illustrated in Fig. 5 instead of the unseparated trace normally obtained as in Fig. 4. Two embodiments are described. It is stated that if the receiver 3 is equipped with a variable bandpass filter 10 (Fig. 6) the passed frequencies combine to form an oscillation which is effectively the transmitted ultrasonic frequency amplitude-modulated by the sequence frequency of multiple echo pulses and this appears on a cathode-ray tube as in Fig. 5. A synchronizing device 1 controls the relative timing of a transmitter 2, a receiver 3, time base 4 for the sweep of cathode-ray tube 5 and the calibrating mark signal generator 6. Ultrasonic pulses transmitted from transducer 8 into workpiece 9 are reflected and reconverted into electric impulses which are fed to receiver 3 via adjustable band-pass filter 10, and thence to the cathode-ray tube 5. Alternatively the separation of multiple-echo impulses may be obtained by giving the receiver a narrow pass range which may be adjusted to the desired part of the frequency range (Fig. 3, not shown). This may be performed by using a superheterodyne amplifier with a variable-frequency local oscillator (Fig. 7, not shown). Specifications 569,858, [Group XL], 569,872, 569,874, 633,827, [Group XXXVI], and 641,095 are referred to.

Filed: 1970-03-09
Abstract: 1310689 Photographic developing apparatus CANON KK 9 March 1970 [8 March 1969(3)] 11166/70 Headings G2A and G2H A photographic sheet P is conveyed through a bath 4 of developer liquid by a drum 3, means being provided for the drum to attract and hold the paper sheet against its surface. As shown, the drum 3 has a perforated surface, and is completely immersed in the liquid as it rotates in direction a. The liquid is circulated by being pumped out of the centre of the drum through a pipe 5, as shown by the arrows in Fig. 2, and re-enters the bath 1 below an arcuate perforated plate 10. The liquid passes first of all through the perforations 9 in plate 10, which impart an agitating motion to the liquid, so enhancing uniform development. The liquid pumped out through pipe 5 causes a suction effect which draws in further liquid through the perforations 2 in drum 3. This suction effect holds the sheet P firmly against the surface of the drum as it passes round. A take-off blade 11 separates the sheet from the drum, and guides it out through rollers 12. If the apparatus is for developing an electrophotographic sheet, the plate 10 may act as an electrode, to prevent peripheral effects arising. In the modification of Figs. 3 and 4 (not shown), a shield is used to block off the perforations not covered by the sheet, to reduce the suction. In the further modification of Figs. 5 and 6 (not shown), the tube 5 passing along the axis of the drum is divided into two compartments which communicate with the interior of the drum, itself divided by a partition (15) into two corresponding compartments. One compartment acts as a liquid inlet, and the other as an outlet.

Abstract: 1,005,567. Magnetic drum stores; electric selective signalling. ULTRONIC SYSTEMS CORPORATION. March 23, 1962 [April 13, 1961], No. 11281/62. Headings G4C and G4H. A data storage system includes a cyclic storage device having means for identifying a plurality of categories of data, means for storing signals representative of data associated with said categories, and operator controlled means for selecting and reading out data, said operator controlled means including a plurality of separate consoles, enabled in turn and individually operable by an operator to select data. The system is applicable to indicating stock prices in a plurality of stockbrokers' offices. As described, a magnetic drum 10 is divided notionally into ten axial sections: (1) a bit timing track 40, (2) a word (equal to 4 bits) timing track 42, (3) a revolution timing track 44 (4) a stock identification code section 12, (5) a " high price " section 16, (6) a " low price " section 20, (7) a " last price " section 22, (8) a " volume of sales " section 24, (9) a " bid price " section 26, (10) an " ask price " section 28. Data in sections (4)-(10) is stored in binary coded decimal form, there being 3 decimal digits in sections (5)-(10) and 5 decimal digits in section (4). The drum 10 is associated with eight consoles, only two of which 50, 52 are shown, the arrangement of console 50, which is typical, being shown in more detail in Fig. 2. The various consoles are enabled in turn by signals applied in turn to lines C 1 -C 8  by a commutator 48 (Fig. 10, not shown) responsive to revolution timing pulses derived from timing track 44. The various stocks are identified by means of a code using four alphabetic characters of 5 binary bits each. In operation, for obtaining information at console No. 1 regarding a particular stock, the stock identification code is set up on a keyboard (not shown) thereby operating a corresponding combination of twenty single-pole double-throw switches 92, Fig. 2. The particular information required (e.g. " high," " low " price &c.) in respect of the selected stock is selected by operating an appropriate one of switches 120. When the commutation signal C1 for console No. 1 occurs, it permits successive repetitions during bit timing periods G1-G4 of the twenty stock identification signals to be gated via gates 110, 112, 114, 116, 118 to a coincidence circuit 64, Fig. 1, to which are also applied signals from the stock identification section 12 of the drum 10. When coincidence is achieved in the circuit 64, an output SL consisting of four shift pulses is obtained which is effective to gate the required information from the selected track section via gates 136, 138, 140 and shift it along shift registers 130, 132, 140, Fig. 2, to twelve relays 142, 144 &c. which are thus energized combinationally to represent the required information. The states of the relays 142 144, &c. are decoded in a relay tree (Fig. 3, not shown) to light corresponding output lamps so that the requested information is displayed in the form of three decimal numbers.
