Abstract: 554,390. Administering anaesthetics. BRITISH OXYGEN CO., Ltd., EDMONDSON, W., and JONES, W. Feb. 14,1942, No. 1996. [Class 81 (ii)] [Also in Group XII] In a vaporizing device for inhalation or for entrainment of a volatile flux in a stream of gas used in the fusion joining of metal parts, the surface of the body of the liquid from which the vapour is to be derived is divided into a number of zones and the gas stream which is to be impregnated with the vapour is constrained to move downwards and impinge on the surface of the liquid in each zone in succession, the gas stream after impingement on the surface of the liquid passing upwards from one zone to the next without bubbling through the liquid. As shown the device consists of a container 10 of high heat conductivity metal, provided with baffles 18, 26, 28 which divide the surface of the liquid to be vaporized into zones which are acted on in succession by a stream of gas admitted from a conduit 21 through a central tubular partition 22. Other partitions 23, 24 and 25 in th: form of concentric bells extend from the conduit 21 to a common level, which is slightly above the surface of the liquid at its highest level and the vapour passes through apertures 27 in the baffles to the outlet conduit 20

Title: Improvements in or relating to circuit arrangements for producing a sawtooth current in an inductance
IPC: H03K4/62
Filed: 1964-01-16
Abstract: 1,016,480. Transistor sawtooth currentgenerating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 16, 1964 [Jan. 18, 1963], No. 2005/64. Heading H3T. In a circuit for producing a sawtooth current waveform in an inductance, e.g. for horizontal deflection in a television receiver, comprising a plurality of transistors having their emittercollector paths connected in series with each other and with the primary winding of a transformer between the positive and negative terminals of a supply source, the primary winding is divided into a plurality of equal winding sections, equal in number to the number of transistors, and the tapping points between the sections are each connected to a respective junction point between two transistors through the series combination of a capacitor and a resistor. In the circuit shown in Fig. 1, the transistors are cut-off during the fly-back by means of pulses 16 applied thereto through transformer 18. Due to charge storage in transistors 13, 14 cut-off does not take place immediately upon application of a pulse 16 but with delays which differ for different transistors. Hence, if capacitor 24 and resistor 25 were not present, there would be a short period after cut-off of one transistor and before cut-off of the other in which said one transistor would have the full voltage of the fly-back pulse applied thereto instead of the voltage being divided between the two transistors. In the circuit illustrated, the capacitor 24 is of large value and a substantially steady voltage of E12 is maintained across it. Current flow takes place from capacitor 24 through whichever of the transistors remains conducting to maintain the voltage across the primary winding substantially at E so that a largevoltage is not applied to the non-conducting transistor. However, the current through the conducting transistor, if a capacitor alone is employed, doubles substantially instantaneously. To prevent consequent. damage to the conducting transistor, a resistor 25 which limits the current flow is inserted in series with the capacitor. The modified circuit of Fig. 2 employs two transistors of opposite conductivity types; this permits the collectors of both transistors to be connected to supply conductors whereby dissipation of heat produced in the collectors is facilitated. The diode 9 is replaced by two diodes 26, 27; since transistors themselves may be operated as bidirectional switches, the diodes may be omitted, but in this case the switching pulses 16 must terminate at the precisely correct moment and preferably transistors of symmetrical design are used.

Title: Improvements in and relating to the production of records for phonographs, gramophones and the like
IPC: G03B31/00
Filed: 1925-01-23
Abstract: 237,857. British Thomson-Houston Co., Ltd., (Assignees of Hoxie, C. A.). July 29, 1924, [Convention date]. Optical apparatus; records, duplicating.-Relates to a method and apparatus for making records, particularly master records, whereby the record need not be cut at the same time and place as the production of the sound, and inertia effects in the recording apparatus is minimized. A photographic record of the voice, music, &c. is first made at any convenient place and time on a film 1, Fig. 1, which is moved behind a slit 21 in a screen 20 whilst a beam of light reflected from a mirror 26 connected with a diaphragm 23 influenced by the sound is directed on to one end of the slit, as described in Specification 180,296. The driving drum 3 for the film 1 is driven by a belt 7 from a countershaft 10 which may be driven directly from a motor 11 or through belts 16, 17 and a governor-controlled friction clutch on a shaft 13. This photographic record is then used in cutting the record by traversing it between a photoelectric cell 45, Fig.- 3, and a screen 48 with a slit 47 on to which a beam of light from a suitable source 49 is directed. The light passing to the cell is varied in accordance with the film record 30 and produces a fluctuating electric current in the cell circuit, which current is amplified by a thermionic valve and controls the cutting action of a recording tool 56 on a record blank 57 driven by a motor 58. The blank may be of disc, cylinder, or other form and the recorder may cut a zig-zag or hill-and-dale trace. The photoelectric cell 45 may be arranged inside a driving drum over which the film passes, and the drum may ba driven as in Fig. 1, but to reduce the inertia effects of the recording mechanism the film drum and the blank are driven at a considerably less speed, for example one quarter of the speed of the film in making the photographic record.

Filed: 1926-01-25
Abstract: 271,536. Marks, E. C. R., (Wico Electric Co.). Jan. 25, 1926. Inductor machines; reciprocating machines. - An ignition generator comprises two magnetic circuits each having a generating winding, reciprocating armature flux-changing means for varying the reluctance of each magnetic circuit and means for timing the production of the E-M-F's so that two E-M-F's are produced simultaneously in the windings un each stroke of the reciprocating means. Fig. 1 shows a unit comprising permanent magnets 11, laminated cores 10 carrying high and low tension windings 17, 13 and a reciprocating armature or inductor 12, and parallel thereto is a similar unit as shown in end view in Fig. 2. Between the -cores 10, 10<1> of the two units is mounted a further set of laminations 33 and magnets. The windings are preferably connected as in Fig. 6 s) that the circuits of both of the low tension windings 17, 17' are opened when either interrupter 19, 20 or 19', 20<1> is operated. The opening of the circuits is timed to occur when one inductor has just seated on its poles and the other has moved away from its poles to a predetermined distance. The interrupter comprises a fixed contact 19 and a movable contact 20 carried by a rod 22 which passes loosely through a bracket 23 on the inductor and has lost motion relatively thereto so that the inductor moves through a predetermined distance before the circuit is opened. The inductor is carried by a bracket 41 loosely mounted on a rod 40 above which is arranged the drive shaft 39, The drive shaft carries a cam which effects the movement of the inductor against the action of a spring 53. For normal speeds, the cam acts on a separately pivoted lever 46 which engages a lug 44 on the bracket 41 and effects the downward movement of the inductor. For slow speeds, springs may be arranged to give a rapid movement of inductor after it has left the armature poles.

Abstract: 943,315. Hydraulic apparatus. ELEKTRO-MECHANIK-G.m.b.H. Jan. 23, 1962 [Jan. 23, 1961], No. 2398/62. Heading F1P. In an electro-mechanical regulating device comprising in co-axial arrangement an electric drive motor 11, a pump 16 secured to the motor shaft 14, a regulating piston 17 and a piston rod 18 in a housing consisting essentially of a motor section 11 and a cylinder section 10, drive motors of different power are adapted for installation in the motor section, the motor section is adapted to be combined through a fitting 26 with cylinder sections of different length, the pump comprises one or more stages 16, 35, 36 connected in series, which number of stages increases as the rated power of the drive motor increases, and parts of the pump compartment which are free when a small number of stages is used is compensated for by filling members and/or varying the depth of penetration of the motor section and cylinder section one inside the other. The drive motor may be varied by increasing or decreasing the number of laminations which are disposed against a shoulder 32 in a sleeve 33 and retained therein by a ring 34, the sleeve being accommodated in the motor section 11 of the housing. The shaft 14 of the motor is guided in a bearing 27 in the fitting 26 and carries in the arrangement shown in Fig. 1, a single pump impeller 16 for pumping fluid in a chamber 24 connected by a sleeve 25, which is extended by the filling member 46, through passages 43 in the filling member to move the piston 17 which is joined by a bridge 19 to the rod 18. The stroke of the device can be varied by exchanging the cylinder section 10 of the housing, the sleeve 25, the piston 17, bridge 19 and rod 18 with others of greater length. When a motor of greater rated power is used, one or more additional pump impellers 35, 36, Fig. 3, may be fitted to the motor shaft and the filling member 46 replaced by one or more members 37, 38 having passages 39, 40 and vanes 41, 42 for guiding the fluid through the stages of the pump and passages 43, 44 for guiding the fluid from the pump to the piston, the depth of penetration of the motor section 11 into the pump section also accommodating the increased number of impellers. The movement of the piston may be effected against a spring 63 and a shock absorber comprising cup-shaped members separated by springs may be fitted between the piston and rod. A seal 28 prevents fluid reaching the motor and pressure above the seal is relieved by a passage 45 leading to the space 24.

Title: Printing machine
IPC: B41F17/00
Filed: 1962-01-23
Abstract: 990,385. Rotary printing machines. J. G. ROE. Jan. 23, 1962, No. 2468/62. Heading B6C. A flexible steel measuring tape is printed by a machine in which the inch and foot graduation marks are applied during the passage of the tape between printing and impression drums 40, 38 whilst the associated numerals, which may be printed in a different colour, are applied as the tape moves over the impression drum 38 and in contact with an endless band printing surface 44 travelling between rollers 46, 48 (not shown). The blank steel tape 12 is fed from a roll 14 adjustably braked by an electromagnetic clutch 32 controlled from a rheostat 34. Variation of the rheostat controls the tension in the tape and thus the resulting distances between the graduations printed thereon. The machine is driven by a motor unit 56, a chain 54 transmitting the drive to the drum 38. Through a spur gear 58 on the drum shaft 39, idler gears 60, a spur gear 62 on the impression drum 41, idler gears 68 (Fig. 2, not shown), and a spur gear 66 on the shaft 64 of the lower pulley 46, the machine is driven in synchronism, the inking mechanisms 114, 116, for the printing drum 40 and band 44, respectively, being actuated by belt drives from respective shafts 41 and 64. An adjustable resiliently mounted roller 50 urges the band 44 against the tape 12 and the drum 38. The band 44 is equal to the length of the required measuring tape, which, on leaving the machine, is checked against a gauge 26. The positions of the numerals printed on the tape by the band 44 relative to the graduations printed by the type 42 carried by the drum 40 are adjustable through the actuation of a knob 88 which, on being rotated, effects the axial displacement of a collar 80, Fig. 5, and thus a slotted plate 78 carried thereon. The hub 70 of pulley 46 is adjustably mounted on the shaft 64 and a pin 74 projects from the hub to ride in a slot 76 formed in the plate 78. By manually controlling the axial position of this plate the angular position of the pulley 46 relative to the shaft 64 is determined. To compensate for variation in the height of the type projecting from the band 44 make-ready strips of cellophane tape 108, 110, Fig. 3, are used, shallow grooves being formed in the rims of the pulleys 46, 48 (not shown), to accommodate the strips as they pass with the band over the pulleys.

Abstract: 588,162. Resistance measurements; current and voltage measurements by low-pressure discharge apparatus. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., SAVILLE, W., and WILLIAMS, M. O. Feb. 1, 1945, No. 2535. [Class 37] A high resistance R to be measured is connected between the cathode C and starter electrode S of a three-electrode coldcathode gas-discharge tube CCT and the resistance value is obtained from a previously prepared calibration curve in accordance with the voltage which has to be applied between the anode A and cathode C to cause the tube just to strike. The operating potential, which may be derived from a dry battery giving from 90 to 220 volts, is applied between terminals 10, 11 in series with a limiting resistance LR, the resistance R to be measured being connected to terminals 12, 13 which may be in the form of testing probes. By adjusting the voltage across the terminals 10, 11 to a value corresponding to the predetermined resistance value, the tube flashes or not according as the resistance R is less or greater than this value. The source of supply may be either D.C. or A.C. If D.C. is used, the tube remains lighted until the potential is disconnected, whilst if A.C. is used, the tube flashes intermittently. To obtain a numerical value of the resistance R, the applied voltage is gradually reduced until the tube just fails to strike, the resistance value being obtained from the calibration curve. Alternatively, a voltmeter may be connected across the terminals 10, 11 and calibrated in terms of resistance. If D.C. is used, the circuit is opened with each change of voltage in order to extinguish the tube. In order to give an alarm if the insulation resistance of a piece of equipment falls below a predetermined value, a permanent connection is made to the terminals 12, 13 and the voltage applied to the terminals 10, 11 is adjusted to correspond to the predetermined resistance value. If the insulation resistance falls below this value, the tube strikes and indicates the condition by its glow. A relay may be employed in place of the resistance LR so as to operate when the tube strikes and close an alarm circuit. The relay may be double wound and arranged on operation to interrupt its own circuit so that a tone is generated in its second winding. The anode A and cathode C may be bridged by a capacitor of such value that when the tube strikes relaxation oscillations are set up and by means of a transformer in the anode-cathode circuit are transmitted over a line as an audible tone.
