Title: Measuring device
IPC: G01B7/02
Filed: 1953-01-19
Abstract: 724,911. Dimension measuring device. THORNTON, A. A. [Cleveland Instrument Co.]. Jan. 19, 1953, No. 1493/53. Class 40 (1) The movable member 70 of an electromechanical transducer is carried by springs 55 with slots 62, 67 and stiffening ribs 60, as shown in Fig. 8, which ensure that the resistance to axial movement is slight whereas the member is stiffly supported radially. The transducer illustrated is of the E-cored differential transformer type and the movable member 70 is formed by a magnetic member 72 threaded with non-magnetic spacers 73, 74 on a non-magnetic bolt passing through the springs, the whole assembly being held together by a non-magnetic nut 77. The pick-up is completed by a casing 100, one end of which houses a hollow stud 92 in which is seated a spring 94 bearing against the end of the movable member. Adjustment of zero position of the member is made by movement of the threaded hollow stud. The transducer is shown applied to the comparison of the size of articles with a pre-set standard and for this purpose is mounted for fine adjustment by a differential screw 35 on a platform, the position of which is adjustable on the base of an L-shaped frame. The vertical arm of this frame carries an anvil 15, the test pieces being inserted between this anvil and the movable member of the transducer. Heat insulating pads 20 and 22 prevent changes of dimensions due to heat conducted from the operator's hand. Specification 669,433 is referred to.

Title: Loudspeaking intercommunication system
IPC: H04M9/00
Filed: 1960-01-15
Abstract: 911,165. Transistor amplifier circuits. STANDARD TELEPHONES & CABLES Ltd. Jan. 15, 1960 [Jan. 20, 1959], No. 1494/60. Class 40 (6). [Also in Group XXXIX] In a loud-speaker telecommunication system substation the microphone and loud-speakers are provided with transistor amplifiers. The microphone is shown in Fig. 2 at 130 and is connected to two stages of amplification comprised by transistors 119 and 106 and to a third push-pull stage comprised by transistors 89 and 90. The output transformer 85 has a secondary winding 131 which provides a rectified voltage applied for automatic gain control to the base of the firststage transistor 119. In Fig. 1, the loud-speaker amplifier is shown in which speech from the line is amplified by a first transistor stage 11, the collector circuit of which has a band-pass filter over which the second transistor stage 12 is fed. Transistors 49, 50 comprise the third and output stage feeding the parallel connected loud-speakers 62. The balanced input transformer of this stage is connected to a potential divider one limb of which is shunted by the negative temperature resistor 53 which stabilizes collector currents in transistors 49, 50. Negative feed-back is taken from the output over the RC combination 64, 65 to the base of the second stage 12. Across resistors 33 in the emitter circuits of stages 11 and 12 capacitors 36 and transistors 35 are shunted. Each transistor 35 is held normally conducting, so that the negative feed-back of resistors 33 is inhibited, by the small voltage produced by forward conduction in a Zener diode 44. Rectified voltages from 143 and 144, obtained from the line signal over transistor 69 tend to cut transistors 35 back so as to decrease the shunt across feed-back resistors 33 and hence decrease the gain of the amplifier.

Title: Improvements in and relating to electrical methods of measuring molecular impuritiesin gases
IPC: G01N27/70
Filed: 1951-01-19
Abstract: 677,880. Measuring impurities in gases. BRITISH THOMSON-HOUSTON CO., Ltd. Jan.19, 1951 [Jan. 20, 1950], No. 1503/51. Class 37. The concentration of a gaseous molecular impurity in a mixture of an inert gas with the impurity is measured by introducing a sample of the mixture at a low pressure into an evacuated envelope containing a pair of electrodes and a small quantity of mercury, transmitting through the sample a constant current of predetermined value slightly in excess of that required to produce a flashing discharge, and measuring the voltage drop between the electrodes to determine the concentration of the impurity. The tube 1, Fig. 1, may be identical with those used for 40-watt fluorescent lamps, i.e. about 4 feet long and 1¢ inches in diameter. The tube is provided with an anode 2 and a thermionic electrode 3, which may be a coil of tungsten wire coated with barium or strontium oxide. The tube contains the inert gas wherein the concentration of a molecular impurity is to be determined, and also a small quantity of mercury which fills the tube with its vapour pressure at the temperature of operation, normally room temperature. The secondary voltage of an adjustable transformer 4 is supplied to a rectifier 6 connected to a filter comprising a pair of shunt condensers 7, 8 and a series inductance 9. A pair of bleeder resistances 10, 11 are connected in parallel with the condensers 7, 8 to stabilize the unidirectional output voltage at terminals 12, 12<SP>1</SP>. A current limiting resistance 13 is inserted as shown. A voltmeter 15 and ammeter 16 measure the voltage drop across the tube 1 and the discharge current therethrough. The current through the tube 1 should be low enough in value to ensure a high ratio of destruction of metastable mercury atoms by the impurity as against destruction by other causes, a suitable value for the size of tube stated being 0.65 milliamperes. Curves 21, 22, Fig. 2, illustrate calibration curves obtained with nitrogen and carbon monoxide as impurities in argon. The dotted line from curve 22 indicates the onset of flashing discharge when the voltage across the tube suddenly falls to about 40 per cent less than its original value. The nature of the molecular impurity may be determined by the fact that if the impurity is such that the voltage across the tube for a discharge current of 0.65 milliamperes lies between 300 and 450 volts, the tube has a positive resistance characteristic when the impurity is nitrogen, and a negative characteristic when the impurity is carbon monoxide. The method is applicable for measuring impurities in any of the rare gases. Specification 695,481, [Group XL (a)], is referred to.

Title: Improvements in or relating to delivery stop motions for textile spinning frames
IPC: D01H13/16
Filed: 1951-01-19
Abstract: 699,110. Delivery stopping arrangements for textile spinning frames. SAUNDERS, E. F., and DRYSDALE, D. Jan. 19, 1951 [Feb. 3, 1950], No. 1526/51. Classes 120(i), 120 (ii) and 120 (iii) A delivery stop motion for a spinning frame including separate detecting means for each spindle responsive to broken ends and separate interrupting means for each roving located in front of the drawing rollers has each detecting means provided with a sensing member and an associated member carrying a further movable member engaged by either the sensing member or the associated member when an end breaks, either of the last two members being subjected to periodic reciprocatory movements. In one form of apparatus, a detector wire 66 is pivoted on pedestals 65 fixed to a plate 58 pivoted at 57 for movement within a box 51 under the influence of bellows for raising the plate and a spring 60 for lowering the plate. Mechanism is arranged to supply the bellows with air intermittently so that the detector wire 66 is periodically moved forwards towards the yarn R<SP>1</SP>. When yarn is present, the contacting portion of the detector wire 66 is drawn downwardly so that the rear end is raised above the end 80 of a lever 78. When yarn is not present, the rear end of the detector wire 66 slides along the top of the box 51 until it hooks upon the end. 80 and the continued forward movement of the wire 66 under the influence of the bellows draws the lever 78 forwards until it closes a switch 87 to operate the roving interrupting device and a switch 95 to light a signal lamp 96. As an alternative indicating device a buzzer may be employed. Closure of the switch 87 energizes a solenoid 150 to remove an arm 149 from a detent 147 on a riser 142 urged upwardly by a spring 144. Upon being released, the riser 142 lifts a cutter bar 130 provided with a serrated edge 131 and a shelf 133 to hold broken ends of roving. The cutter bar 130 is located.on the delivery side of a trumpet 40 immediately in front of the drawing rollers. Other forms of cutting device described include upwardly and downwardly swinging pivoted cutter bars. The cutter bars may be actuated by pneumatic means. Instead of a detector member actuated by pneumatic means, the feeler may be cam operated to swing forwards against the yarn. The feeler member may be adjusted to press upon the yarn with different pressures depending on whether a single or double roving is being spun, so that if one component of a double roving breaks the yarn being spun will be broken by the feeler member.
