Title: Glass bulb blowing apparatus
IPC: C03B9/40
Filed: 1967-05-16
Abstract: <PICT:1123856/C1/1> In order to properly align the feed rollers 20 of a glass blowing machine with the outlet O of the glass supply, the whole machine is mounted on rails 7 by wheels 9 and thus movably longitudinally. The rails are carried on a base 8 pivoted about point 2, remote from the rollers. The arcuate relative movement between the rollers and the outlet provides a substantially straight line motion at right angles to that afforded by the rails.  This latter movement is obtained by driving a chain 11 through a differential variable speed device by motor 15.  The arcuate adjustment is obtained by hand wheels 3, 4 (5, 6).

Filed: 1923-09-11
Abstract: 218,157. Florez, L. de. Sept. 11, 1923. Cases; turntables; tone-arm joints.-A portable gramophone has the tone-arm pivotally mounted on a freely hinged platform, the hinge, about which the tone-arm can move vertically during the playing, being situated between the vertical projections of the ends of the tone-arm, so that the effective pressure of the stylus on the record during playing is reduced. The hinged platform permits of the tone-arm being housed within the case by manipulation of the tone-arm itself. As shown in Figs. 1 and 2, the tone-arm 13<1> is pivoted by a yoke 15<1> and pivot 14<1> to a hinged platform 16<1>, the hinge 19<1> of which is on the side nearer the stylus 18<1>. When not in use, the tone-arm is housed in the sound-amplifying chamber which extends across the case, the tone arm being first turned on its pivot 14<1> and then turned down on the hinge 19<1>. A portion 22<1>, Fig. 4, of the soundamplifying chamber may be carried by the platform 16<1> to prevent variation in the size of the chamber, and consequent variation in tone, due to an untrue turntable. In a modification, Fig. 7, the tone arm is adapted to be housed in the space beneath the turn-table, which is mounted so that it can be moved out of the way for the purpose. The turntable spindle carries a transverse arm 30<1> at the end of which the turntable 6' is hinged. A spring catch 33<1> holds the turntable down in its operative position.

Title: Electromechanical telephone switching systems
IPC: H04Q3/00
Filed: 1923-09-12
Abstract: 225,939. Baron, H., (Aldendorff, F.). Sept. 12, 1923. Drawings to Specification. Automatic exchange systems; selectors.-In a system in which the initiation of a call on a line or trunk completes the starting circuit for a single preselected call-finder, the starting circuit being extended to the next idle finder immediately the started finder commences hunting so that a second finder can be started up to extend a second call whilst the first finder is still hunting, the second finder is prevented from being started up by the first call by means of an impulse sent back from the started finder, which impulse, either by operating an auxiliary line relay or by partially operating a marginal cut-off relay, disconnects the normal line relay and so dissociates the line or trunk from the common starting wire. The invention is described with reference to a system identical with a system described in Specification 203,724, in which both call-finders and connectors consist of switches the movement of which is controlled by the braking action produced when an electric current is passed between contacting, conducting and semi-conducting surfaces. Specification 201,679 is referred to.

Title: Improvements in or relating to bridge circuit arrangements especially for indicatingthe intensity of high frequency electric fields
Inventor: TAYLOR JOHN CHARLES EDWARD
IPC: G01R21/00
Filed: 1954-08-07
Abstract: 812,129. Power measurements; measuring bridges. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 5, 1955 [Ang. 7, 1954], No. 23009/54. Class 37. [Also in Group XXXVIII] A measuring circuit comprises a first electric bridge containing a temperature-sensitive first impedance responsive to a parameter producing a temperature change, and a second similar bridge containing a second temperature-sensitive impedance responsive to the ambient temperature of the first impedance but irresponsive to the parameter; the bridges being connected in series in an energizing circuit passing direct and oscillatory components of current and means being provided responsive to the latter for deriving a signal representing balance variations of the second bridge, together with means responsive to such signal for regulating the direct component so as to nullify such variations and stabilize the first bridge for ambient temperature changes. Power in a waveguide or coaxial line is wholly or in proportional part applied to heat a first thermistor connected at BD in a bridge 1 comprising fixed resistances 2, 3, 4 and unbalance meter 7 whose deflection is a measure of the power. A second bridge 10 energized in series with the first comprises fixed resistances 12, 13, variable resistance 14 adjustable for similarity to bridge 1, and across AC a second thermistor exposed to the same ambient temperature as the first but in which no power is dissipated. Excitation for the bridges is derived from a D.C. source in series with a triodeconnected pentode 22 whose control grid is energized by the adjustable 1 kc/s. output of Colpitts oscillator triode 26a so that the excitation current contains a 1 kc/s. component, and the unbalance output of bridge 10 (varying in amplitude and phase sense in accordance therewith) is coupled over windings 20, 21 to pentode amplifier 45, double triode balanced cathodecoupled phase splitter 56, and double diode tuned phase discriminator 93, 95 which is also supplied with a 1 kc/s. reference signal from oscillator 26a over triode amplifier 26b, capacitance 83, resistance 84, and the cathode circuit of the balanced phase splitter, so that variations of ambient temperature produce variations of balance of bridge 10 with consequent variations of phase sense and amplitude of its 1 kc/s. output, which are converted by the discriminator to corresponding variations of magnitude and sense of a direct voltage superimposed on the 1 kc/s. grid excitation of pentode 24, whereby the D.C. excitation of the bridges is varied until bridge 10 is rebalanced and bridge 1 is compensated for ambient temperature variations. The device is applicable to measurement of other parameters which produce temperature change of a thermistor or other temperature-sensitive resistive elements.

Title: Improvements in or relating to phototypesetting apparatus
IPC: B41B27/00
Filed: 1962-06-15
Abstract: 1,008,146. Photographic type-composing apparatus. HARRIS - INTERTYPE CORPORATION. June 15, 1962 [June 15, 1961], No. 23142/62. Heading B6W. Photographic type-composing apparatus comprises means for projecting character images of different width along a common path, mounting means for photo-sensitive record material movable stepwise along the composed line in relation to said common path, a stepping motor having an output member mechanically connected to the means for producing said stepwise movement, and means for producing digital character width or spacing information and applying it to the motor to cause digital stepping of said output member. Photo-sensitive film is fed from a spool comprising wheels 290, 294, Fig. 4, the latter being adjustable for width, between sprockets 312, 314 and wheels 303, the sprocket 314 and one wheel 303 being adjustable for width, downwards into a loop, upwards over stationary cross-members, and down between sprockets 30 and wheels 32, one sprocket and wheel being adjustable for width. The sprockets 30 are rotated for line spacing through a long gear 272 from a stepping motor 275 controlled by the end-of-line signal, or by special signals for producing vertical leads, super-script or sub-script. To keep the film loop of constant depth, a stepping motor 310 driving the sprockets 312, 314 is actuated by contacts on the gear 272. The sprockets 30 and wheels 32 are mounted on a lightweight carriage 35 slidable along rails 45, 46 and carrying a rack 65 by which it is driven stepwise for letter and word spacing by a stepping motor 70, thus moving that part of the film in the exposure position. The end-of-line signal releases a clutch 68 to allow a spring 258 to return the carriage under the control of an eddy current brake 262, 264. The motor 70 can be stepped backwards by using a reversing switch if desired. The characters are carried on a constantly rotating disc 10, Fig. 10, light passing from a source 12 activated at the requisite moments through the selected character and adjustable lenses 15 on to the film 20. A font selection reflector 107 is provided, also a refraction device which deflects the light through half a spacing increment, so as to halve the necessary speed of the motor 70. The refraction device is swung between two positions constantly by solenoids 250, 252. Selector circuits 82 are supplied with information from a code tape 85 and also from photo-cells 92 actuated by light from sources 93 to indicate the position of the disc. When the information from these two sources corresponds, signals are passed to controls 80, 95, to activate the light source 12 and also a gas discharge tube 96, whereby character width information is conveyed by means of code dot transparencies in the disc 10 and photo-cells 100 to a computer 110 and thence by means of circuits 125, 130 to the motor 70. Specifications 768,374 and 998,711 are referred to.

Title: Current limiting control for an electric power system
IPC: H02H7/085
Filed: 1972-05-17
Abstract: 1385239 Automatic control of speed GENERAL ELECTRIC CO 17 May 1972 [15 June 1971] 23179/72 Heading G3R An automatic speed control arrangement for a motor is provided with a current sensing circuit which, when the current exceeds a pre-set value, provides a signal to a converter supplying the motor, to over-ride the normal control signals and limit the motor current. In an embodiment, a three phase induction motor 10, fed from a D.C. source 14 through a variable frequency and voltage power converter 12 which may include SCR's or thyratrons, has its speed controlled by comparing one or more feedback signals eg from a motor driven tachogenerator 25 with a reference from source 20, any difference being used to vary the rate of firing pulses to the converter and thus regulate the motor speed. If the inphase component of motor current, as detected by current transformers 28, 30, 32 and detector 26, exceeds a predetermined value, e.g. 1.5 times rated, a fixed D.C. from overcurrent signal generator 22 is fed to control signal generator 18 to over-ride all other inputs, causing the motor current to fall below the predetermined value, by adjustment of the converter output frequency and voltage, whereupon the speed loop regains control. The polarity of the output from generator 22 may depend upon whether the motor is generating or motoring. The control signal generator 18 described with reference to Fig.2 (not shown) could include an operation amplifier (40) with diode clamping and an integrating amplifier (42). The overcurrent signal generator 22 also Fig.2 (not shown) may include transistor switches that switch on and off at different current levels. The induction motor 10 may be replaced by any A.C. or D.C. motor.

Title: Dual beam radiometer
IPC: G01J5/60
Filed: 1973-05-16
Abstract: 1422380 Measuring atmospheric temperature radiometrically E F FLINT 16 May 1973 23212/73 Heading G1A A radiometer is used to measure atmospheric temperature as an indication of the presence of clear air turbulence. Radiation from the atmos phere is focused by lens 13, which may be rotated for scanning if desired, on to detector 11 (thermistor bolometer). A two sector chopper disc 30 is rotated to allow the atmospheric radiation to reach detector 11 twice per cycle, the other quarter cycles, radiation from a black body source 25 being reflected on to the detector. Rotated in synchronism with disc 30 is a four sector filter disc 40. This can have two equal adjacent sectors having a 1.0 micron bandwidth peaked at 14.2 microns with the other two having a 0.5 micron bandwidth peaked at 13.8 (spectral bands on the edge of a CO 2  absorption band). In this way a four part signal is derived comprising detection of (a) atmospheric radiation at the first wavelength; (b) black body reference radiation at the first wavelength; (c) atmospheric radiation at the second wavelength; (d) black body radiation at the second wavelength. Alternatively, the two sectors corresponding to passage of black body radiation may be peaked at the same wavelength 13.0 microns which is however different from the two wavelengths for atmospheric radiation. To correct for altitude variation errors, an external probe 80 controls the black body source 25 and maintains a constant relationship with the outside temperature.

Title: Improvements in the manufacture of filaments, films and like articles comprising regenerated cellulose
IPC: D01F2/06
Filed: 1945-09-11
Abstract: Viscose is extruded or cast into an acid setting bath of pH less than 1, and the partially regenerated cellulose filament, film, or like article so formed is stored in a weakly acidic aqueous sodium salt solution so that the pH of the acid-laden article is raised to a value greater than 1 but less than 7, and the article is maintained in this storing solution until the time when it is desired to wash the article to remove the acid therefrom.  This treatment enables the article to be stored without hindering the process of regeneration from proceeding to completion and without risk of acid deterioration of the regenerated cellulose.  The operation of tashing the freshly formed articles may thus be deferred as required.  The pH value may be raised by spraying or immersing the filaments or other articles in an aqueous solution of sodium sulphate, phosphate, acetate or phthalate.  A solution containing 10-30 per cent of sodium sulphate may be used.  If desired, the aqueous sodium salt solution may serve as a plasticizing agent during stretching of the filaments and it may be applied to the material as it advances over the stretching reel or other stretching device of a continuous spinning system.  The solution may be at room temperature or at 60-10 DEG  C.
