Title: Improvements in or relating to electrical measuring circuits
IPC: G01R23/00
Filed: 1946-01-21
Abstract: 629,244. Frequency measurements. STANDARD TELEPHONES & CABLES, Ltd., DUNN, R. H., and McWHIRTER, E. M. S. Jan. 21, 1946, No. 1984. [Class 37] [Also in Group XXXVIII] An electrical measuring circuit comprises an input under control of a factor to be measured from which discrete charges of energy are applied to a condenser associated with a Miller integrator circuit, and an additional circuit associated with the condenser whereby the potential across the condenser may be reduced, and means for measuring the rate of reduction. Fig. 1 shows a circuit suitable. for measuring the total quantity represented by a number of operations, which need not all be of the same value. For each operation, the contacts IRI change over to connect a negatively-charged condenser CCI to the input terminal IT of the integrating circuit. Additional condensers CCI are provided for series of other operations, each series having a different but constant value represented by the amount of charge in the appropriate condenser CCI. The condensers CCI discharge into a main condenser C which forms part of a Miller integrating circuit comprising a pentode valve PV. A neon tube NT provides a constant voltage drop between the anode of valve. PV and the plate of condenser C. The arrangement is such that the point OT connected to condenser C, rises in potential, the amount of potential rise for each input impulse being independent of the voltage across condenser C, due to the effect of the Miller integrator circuit. The potential of the point IT remains substantially constant. The potential at the point OT thus represents the integral of the various input quantities. In order that the circuit may continue to operate indefinitely, means for periodically discharging condenser C are provided. When the potential at point OT reaches a predetermined level, a cold cathode tube CCT fires and operates relay A which operates a counter M, and also operates a slow release relay B. The contact b2 of relay B connects a positively-charged condenser C. Contact b1 of relay B disconnects relay A. The meter M thus measures the number of discharge operations, and indicates the integral of the input quantities. An alternative arrangement is shown'in Fig. 2, in which the discharge of condenser C is established by means of a steady leak circuit, instead of an intermittent discharge arrangement. The potential from point OP is passed through a long time 'constant network to the grid of a cathode follower tube CFT. The cathode circuit of tube CFT is connected through a high resistance CM to the input point IT. This arrangement results in a leakage discharge path for condenser C, the value of which is controlled by the potential of the point OP, and for a constant rate of input impulses, the circuit stabilizes itself so that the leakage between two impulses just equals the charge due to each impulse. The potential of the cathode of tube CFT is measured by a meter MCI, which thus provides a means of rate measurement.

Title: Improvements in or relating to the construction of barrels, casks and like articles
IPC: B27D1/08
Filed: 1936-01-24
Abstract: 465,372. Veneer casks &c. HALILA, Ltd. (Treistman, S.) Jan. 24, 1936, No. 2336. [Classes 145 (i) and 145 (ii)] [Also in Groups XVII and XVI] Bilged casks and like articles are made from a number of veneer shells shaped in a heated mould and subsequently united by adhesive in a press. A damp cylindrical veneer shell 4, Fig. 1, is held by advancing two male press-members 2 by a hydraulic ram 5 at each end, or by wrapping the sheet round the members 2, whereafter these male members and female members 3 are actuated by the presses 5 and pairs of presses 6 to bring the two halves of the press together so that projections 9 engage recesses 9a. The ends of the veneer are then engaged by flanged rings 2a carried on rods 10 and actuated by a handle 13, the rings being held in engagement with the veneer by pins engaging the rods 10 and plates 11 on the rams 5. The shaping takes place under the influence of heating piping 7. Removal of the female members 3 permits rapid cooling of the outer surface of the veneer while the inner surface is heated. The melting edges of the shell are tapered to give a scarfed joint, and three shells, with diagonally arranged grain, are nested to form a barrel, adhesive being placed between the shells. The consolidating press, shown in Fig. 5, comprises a fixed lower female member 14, and an upper female member 14 actuated by hydraulic rams 17, and a male member 18, 19, 20 movable by a hydraulic ram 24 and provided with a rubber &c. bag 27 through which hot water &c. under pressure can be circulated. The veneer shell damped on one side is placed within the lower member 14, the male member advanced upwardly and the second female member 14 moved downwardly till dowels 26 engage both female members. Hot water &c. is then circulated within the female members and within the rubber bag. Levers or other hand actuated mechanism may be substituted for the hydraulic apparatus. The heads may be in the form of plywood or other discs secured, e.g. by gluing or otherwise securing one head in position during the process of securing the shells together, and thereafter securing the other end by a metal ring fitting the barrel rim and bent beneath the head. In another form two part spherical discs are connected adjustably at their centres, so that these may be .drawn together by a screw &c. to cause the peripheries to enter the croze.

Title: Apparatus for evaluating the acoustic quality of an enclosure
IPC: G01H7/00
Filed: 1944-02-11
Abstract: 574,749. Sound measurement. WESTERN ELECTRIC CO., Inc. Feb. 11, 1944, No. 2560. Convention date, Nov. 17, 1942. [Class 118 (ii)] [Also in Group XXXIX] In an apparatus for evaluating the acoustic quality of an enclosure, the echoes of a sound pulse produced therein are received and indicated with relatively increasing effect as they fade. As shown, a condenser 11, charged by a battery 10 through a resistance 12, discharges at intervals through a Thyratron tube T1 and a potentiometer 13 and causes a short sound pulse to be emitted by a loudspeaker 20. A microphone 21 picks up this sound pulse and any echoes reflected from walls or other surfaces. The output from the microphone 21 is amplified and transmitted through the transformer 23, the weighting circuit 24, the transformer 25, the potentiometer 26 to the amplifying valve T2, the output from which after transmission through a rectifier 40 is indicated by an ammeter 50. The discharge of the tube T1 through the potentiometer 13 causes the anode current of a valve T3 to be sharply reduced and then gradually to increase and flow through the weighting circuit 24, the impedence of which is initially high but is gradually decreased to a value corresponding to the anode current of the valve T3. The initial pulse is, therefore, not transmitted to the meter 50 but successive echoes by the gradually restored transmission of the weighting circuit 24 contribute to the reading of the meter 50 and this effect, produced by each recurrence of a sound pulse, causes a steady reading of the meter 50.

In an arrangement in which a photo-conductive sheet is subjected to successive exposures each followed by an electrolytic development in a dye bath, a rinsing step to recover its dark adaptation and a drying step to restore its uniform photosensitivity, the sheet is carried both during exposure and its subsequent treatment on a fixed or movable platen. In one form Fig.7, (not shown), the platen is movable to submerge the sheet in developer baths which are each successively moved into the development position. As shown, a sheet 28 having a photo-conductive insulating coating on a conductive backing is retained by suction on a platen 14. The top of the sheet is secured by members 98 forming the cathode connection. After exposure to the projected colour separation image of a multi-colour negative, the appropriate developer bath, having a plate, strip or reticulated anode 74, is raised in cradle 32 by hydraulic cylinder 66. After development, bath 16 is lowered on to turn table 18 which is then free to align the next bath 16 with lifting cradle 32. As water collecting funnel is moved from 68B to 68A, a stream of water is spread over the coated face of the sheet by retractable water knife 20 and the platen is washed by spray 78. The washing water may be warmed to effect the dark adaptation of the sheet or, alternatively, it may be subsequently heated by infrared radiation or warm air. Air knives 22 are movable vertically by means of hydraulic cylinder 62 to dry both the sheet and platen. It is stated that either A. C. or D. C. may be used for development and that the developer may be poured on to the sheet through an orifice containing an anode wire.
