Patent GB-1371173-A (GB)
Title: Coordinate measuring apparatus
IPC: F41J5/06
Filed: 1973-01-19
Abstract: 1371173 Acoustic position-finder M S INSTRUMENTS Ltd 19 Jan 1973 [19 Jan 1972] 2477/72 Heading H4D [Also in Division F3] Apparatus for determining the co-ordinates of a pressure-wave-emitting object (e.g. a bullet) in a plane includes two elongated members arranged in the plane and with a given angle between them, a pair of transducers on each member, the transducers of each pair being spaced along the member and responsive to a vibration travelling along the member and initiated at a point on the member by a pressurewave from the object, and a circuit for timing the interval between the arrival of the vibration at the two transducers of each pair. In the target embodiment shown in Fig. 1, transducers 3, 4, 5, 6 are on orthogonal rods 1, 2 and detect rod vibrations induced by impingement of a bullet's circular shock-front on the rods. If the impingement point is displaced from the rod centre the vibration arrival time difference for transducer pair 3, 4 or 5, 6 is measured digitally by a respective timing circuit 8 or 9 which also gives an indication of which of the two associated transducers first received the vibration. The measurement is compensated for vibration velocity changes with temperature (sensed at 10, 11), and may be recorded on an XY plotter. Each transducer is coupled to the (remote) timing circuit through a similar processing circuit, detailed in Fig. 2. Thus the output of transducer 3 is fed via a high-pass (>10kHz) amplifier 13 and threshold detector 17 to trigger a monostable 22 whose output is converted at 31 to positive and negative versions for driving a transmission line. The line receiver (not shown) receives these versions in a differential amplifier whose output pulse is steered by a logic circuit to either the start or stop input, as appropriate, of the timing circuit 8. The use of dual-polarity versions enables in-phase noise pick-up on the line to be rejected. To prevent re-triggering of monostable 22 while the rod vibration is decaying, a lock-out monostable 26 is provided. A calibration facility comprises a push-button 47 operating a pulse generator 44 for energizing transducers 3 and 6 as transmitters, resulting vibrations being received by transducers 4 and 5 and their propagation times along the rods being registered by the circuits 8, 9. In modifications rods 1 and 2 may cross each other, and a third rod othogonal to the plane may be added, together with associated transducers and timing circuitry, for obtaining a three-dimensional measure of the bullet's path. If several targets are in use, the output of a transducer associated with a particular firearm can be used to enable the apparatus of a particular target only when that firearm is fired.

Title: Improvements in and relating to the drying of soap and the manufacture of soap powder, flakes or the like
IPC: C11D13/26
Filed: 1945-11-30
Abstract: <PICT:0581203/III/1> Moisture is removed from liquid soap, which has been preformed, which is free of glycerine or fillers, and which contains about 70 per cent. of soap and about 30 per cent. of water, by spraying the liquid soap into a chamber maintained under such conditions of temperature and high vacuum that the temperature of the soap falls below its solidifying point immediately on entering the chamber, the dried or partially dried soap deposited from the spray being agitated.  The liquid soap may be continuously sprayed into the chamber and the soap deposited from the spray continuously removed from the chamber, or alternatively a batch of liquid soap may be sprayed into the chamber, the water extracted being collected and the soap deposited from the spray being removed from the chamber only when the desired amount of water has been extracted.  The heat necessary for the process may be provided by superheating the liquid soap prior to its entry to the chamber or by heating the chamber by means of a steam jacket or by means of a heating coil within the chamber, or by a combination of these means.  The alkalinity of the product may be controlled by introducing into the liquid soap spray nozzle supply conduit, or into the chamber direct, during the process, carbon dioxide or a fatty acid.  If the temperatures employed and degree of vacuum used is sufficient to deprive the liquid soap of all but about 5 per cent. of the moisture, a soap powder may be produced within the chamber, while if the process is carried out to leave larger proportions of moisture in the product a plastic solid may be produced.  The plastic solid may leave the apparatus through an outlet provided with a die plate so that the soap is extruded in ribbon or bar form, and the ribbon can then be disintegrated into flakes or chips.  In the drawing liquid soap is sprayed through nozzles e1 into a chamber f provided with an outlet conduit h through which water vapours and gases may be drawn away by steam ejectors or any suitable vacuum or pressure-reducing pump and with a helical agitating blade k mounted to revolve on a horizontal axis.

Abstract: 365,333. Folding chairs. LLOYD, H. A., 284, Seven Sisters Road, Finsbury Park, London, and WRIGHT, F. A., 62, St. Georges Park Avenue, Westcliff-on-Sea. Jan. 26, 1931, No. 2545. [Class 52 (ii).] A chair frame comprising two frames pivotally mounted one within the other by a pivot arranged i n t e r - mediate of their ends, and a strut frame pivoted to one frame and engaging notches in the other, has a seat frame pivoted to the same frame as the strut frame, the outer end of said seat frame being adapted to be supported on the notched frame on the side of its pivotal connection to the frame carrying the strut frame opposite to that on which the strut frame engages the notches. An inner frame b, strut frame c, and seat frame / are pivotally connected to the outer frame a at d, e, and g respectively. By rotation of the frame f about the pivots g to the position shown in broken lines, the seat frame bears upon the frame b and can support a load. A fabric seat is attached at one end to the front bar k of the seat frame and, at the other, ot a spring roller i within a casing h on the frame a. When not in use, the fabric is rolled up within the casing, the bar k assuming the position shown in full lines. Too rapid movement of the seat frame is prevented by providing a dashpot comprising a cylinder l, connected to a side member of the seat frame, and piston-rod pivoted to the outer frame at p. The cylinder or piston is provided with the usual aperture, which may have means for adjusting the rate of flow of liquid or air therethrough. Distancepieces q may be interposed between the frames where the pivots pass, so that risk of injury when the chair is folded is diminished. The pivots d may be formed at the ends of a tie bar. The disposition of the frames may be varied, for example the frames, a and b may be the inner and outer frames, respectively.

Title: Improvements in or relating to voltage comparison circuit
IPC: G06K9/00
Filed: 1960-01-25
Abstract: 888,718. Electric tests. BURROUGHS CORPORATION. Jan. 25, 1960 [Jan. 29, 1959], No. 2685/60. Class 37. [Also in Group XIX] A voltage comparing circuit, e.g. for use in character recognition apparatus of the kind in which a waveform derived from the sensing of a character is sampled in a tapped delay-line and the samples applied to resistive correlation circuits one for each character, comprises an amplifier 18, Fig. 1, which produces a feed-back signal which is equal to a predetermined proportion of the highest signal from any correlation circuit and opposite to it, the feed-back signal being subtracted from the signals from all the correlation circuits and the highest difference is used as input to the amplifier 18. Only one of the lines, that relating to the sensed character, should then have a positive signal and if more than one is positive an error or reject signal is generated. The error signal is therefore produced if any of the voltages being compared exceeds a predetermined proportion of the highest. In a simple form, Fig. 1, showing only three correlation circuit output lines 11, 12 and 13 are the outputs from the correlation circuits and have voltages say 10 v., 8 v. and 9.5 volts respectively. If it is desired to produce an error signal when any signal exceeds 9/10ths of the highest, a feedback voltage of 9 volts is required from amplifier 18. Points 22, 25 and 26 are connected to lines 11, 12 and 13 through resistors 20, 27 and 29 and to the feed-back line through equal resistors 21, 28 and 30. These points are therefore at a potential mid-way between the input on lines 11, 12, 13 and the feed-back voltage. Since the latter is negative this potential is half the difference between the input and feed-back signals. Amplifiers 24, 31 and 32 having a unity gain apply these differences to a mixer 34 consisting of a diode OR gate so that point 33 has the potential of  half the highest difference. These differences are +0.5 v., - 1 v. and +0.25 v. so that the input to the amplifier 18 is +0.5 v. The amplification factor is- 18, producing the feed-back voltage of - 9 v. Where any output from the amplifiers 24, 31 and 32 are positive corresponding lamps 14, 15 and 16 light. In this case the correct lamp 14, lights and also lamp 16 since the signal on line 13 exceeds 9/10ths of the highest signal and this produces an error signal to reject the character. Gates between the amplifiers 24, 31 and 32 are opened by a sampling pulse signal when the waveform is properly positioned in the delay-line.

Filed: 1947-01-29
Abstract: 626,919. Sorting coins. JONES, R. G. Jan. 29, 1947, No. 2749. [Class 27] Mixed coins or the like in a hopper 10 are delivered by an endless belt 11 to a curved deflecting plate 14 which turns them through approximately 180 degrees and deposits them onto a transversely and longitudinally inclined sorting table 15 having a turned up edge 16 for supporting the coins as they roll down it. The sorting table has a series of tapered apertures, e.g. 20, 21 and 22, of progressively increasing height in the downward direction of the table, so that the coins fall through an aperture appropriate to their diameter and are passed to collecting tubes 24-29 for the different denominations. In the case of coins, such as shillings, which are close in diameter to the next larger coin, the sorting table aperture is bulged upwardly somewhat to ensure the passage of the coin through the aperture'whilst discriminating against the larger coin. The several sorting apertures may be replaced by a continuous tapering slot extending lengthwise of the table. A roller 32 ensures the coins passing singly up the belt 11. A plurality of units as above may be combined in the one apparatus, in which case a single wide belt may be used in place of separate belts 11. ------

Title: Memory system

Filed: 1970-01-21
Abstract: 1280772 Buffer memory system RCA CORPORATION 21 Jan 1970 [22 Jan 1969] 2876/70 Heading G4C The invention relates to a buffer memory system for use in communication between a main memory and a data processor. In one embodiment (Fig. 1) a memory address from a processor is applied to address register 12, 14 and consists of two portions, an address subset k defining a location in a memory and an h subset. Several buffer memories may be addressed and each stores a word composed of two portions, a data word portion and an address word portion. The k address subset is applied to a decoder 16, 18 and accesses a word having an address portion. The h subset is applied to a comparator 36, 38 which also receives the address word portion from the memory and in the event of agreement the comparator enables a gate 32, 34 allowing words to pass to the processor. For a word to be entered in the memory an address is applied to the address registers and supplied to the memories. The memory having the correct address word as determined by the comparator receives a word from the processor via an AND gate 44, 46. A processor may communicate with a plurality of buffers to increase the speed of access or a plurality of processors may communicate via a plurality of buffers with a main memory. In the latter case the address of data in the main memory is the address applied to the address register and to the buffer registers with the least significant digits of the main memory address defining locations in the buffer memories and the most significant digits of the address being stored in the buffer memories as address words. The buffer may comprise a content addressable memory (Fig. 4) with a separate comparator for each location arranged to enable word select logic in the event of an inequality to provide to the address decoder an address at which a new data word is to be stored. When an address word is supplied by the processor it is compared to the address word part of every stored word in the buffer memory and in the event of equality the data part of the word is transmitted to the processor via OR gate 48. If the address is not found the address is transmitted to the main memory to cause read out of the required word which is transmitted to the processor and also stored in the buffer memory at a location specified by the word select logic. Further buffers memory systems are described wherein address words are unequally divided to form the k and h subsets and wherein a k address can access two words only one of which can contain the correct h subset.
