Title: Improvements in and relating to the production and/or modulation of electric currents
IPC: H03B13/00
Filed: 1930-07-22
Abstract: 366,053. Producing, rectifying, or modulating alternating currents. HARRIES, J. H. 0., Shirley, Old Road, Frinton-on-Sea. July 22, 1930, No. 22055. Addition to 328,680, [Class 39 (i), Electric lamps, Arc &c.]. [Classes 39 (i) and 40 (v).] A cathode-ray tube is made to act as a modulator, amplifier, rectifier or generator of electric currents. According to the parent Specification a cathode ray is caused by the input currents to oscillate in one or two dimensions while impinging on a " record " so constructed as to vary the current in the output circuit, which includes the electron stream. The record may constitute either an electrode, which may be fluorescent, or a screen. According to the present invention the record is of a non-periodic character. The jet, which is " saturated" and may be of circular or strip-shaped cross section, may impinge on an electrode 8, Fig. 2b, after passing through a screen 9 having a triangular aperture, the current being varied by movement of the cathode jet relative to the screen. The screen may consist of thin nickel sheet and may have a rectangular or circular aperture or present a straight edge (Figs. 2a, c, d, not shown). Alternatively the jet may impinge on and move in relation to a resistance member 42 or 43, Fig. 5, which may consist of a sputtered metal film and may have a centre tapping as at 14 (Figs. 2e, f, not shown). This member may have lateral extensions 20, Fig. 2g, to permit of double variation of current strength by movement of the jet in two dimensions ; or a straight-edge screen 18, Fig. 2h, may be used in conjunction with a resistance member 42 for the same purpose. Inductance or capacity may be used instead of resistance. In Fig. 5 the first cathode-ray tube 30 acts as an amplifier, bv variation of the fraction of resistance 42 included in circuit with the cathode ray. Tube 31 acts as a rectifier, the ends of resistance 43 being connected together so that the output voltage depends on the distance from the centre-tapping 14 at which the jet 36 impinges on the resistance 43. The input and output circuits may be arranged to produce a negative-resistance effect. For modulation, the jet may be caused to move over a twodimensional " record by means of two pairs of deflecting electrodes arranged at rightangles to one another, the carrier oscillations being applied to one pair and the modulating oscillations to the other. The tubes may have internal metallic deposit on their walls, internal collector electrodes, electrostatic screens, or fluorescent screens, and may contain more than one cathode jet.

Title: Improvements in extrusion presses for moulding tubular articles from plastic materials
IPC: B28B21/54
Filed: 1931-08-04
Abstract: 391,505. Extruding pipes from clay &c. WATKINS, G. L., Heathfield, Lake Road North, Cardiff. Aug. 4, 1931, No. 22074. [Class 87 (ii).] In extrusion presses for moulding tubular articles, the core 5, or mouthpiece 4, or core-holder 8, or any combination thereof is constructed to give an elongated scarfed or partly scarfed joint to the sectors of plastic material divided by the arms 7 and pressed through the holder 8. Each or any of the members 4, 5, 8 is or are formed with helically twisted members so as to give a helical twist to the material. For this purpose, the arms 7 may be twisted, Fig. 7, and of S or ogee shape, the mouthpiece 4 may have inclined or helical vanes 6, or the core similar vanes 13. The core is of conical shape with a cylindrical end 11 forming an annular orifice 12 with a die ring 9. The vanes 13 are deepest near the holder and merge into the surface near the end 11. With vanes on either the mouthpiece or the core, a partly scarfed joint is produced ; if on both, the joint is completely scarfed. If the inclinations of the vanes on the mouthpiece and core are opposed, a long V-joint is formed. The vanes may be single or two-part and may be integral with the members 4, 5 or detachably secured thereto by studs passing through or into the walls. The press may comprise a rotary consolidating knife 2, an extrusion worm 1 and also dropping rings 10 if socketed ends are required. Specification 391,181 is referred to.
Patent GB-724632-A (GB)
Title: Pneumatically operated control apparatus
IPC: G05B11/50
Filed: 1953-08-11
Abstract: 724,632. Fluid-pressure servomotor-control systems. FOXBORO CO. Aug. 11, 1953 [Aug. 21, 1952], No. 22154/53. Class 135. Control apparatus for maintaining a variable condition at a desired value comprises a fluidtight casing 62, Fig. 2, which contains two opposed nozzles, one, 90, communicating with the atmosphere and the other, 96, with a fluidpressure source, a baffle 76 mounted between the nozzles, opposing bellows 72, 74 acting on the baffle and each in restricted communication with the interior of the casing, the resistance of one restriction being greater than that of the other, and means to exert on the baffle a force proportional to the departure of the condition from the desired value, the arrangement being such that a fluid pressure that is a predetermined function of the value of the condition is established in the casing. In an application of the invention, the fluid flowing in a line 10, Fig. 1, is passed through an orifice plate 12 and the pressures on the two sides of the plate are applied to a controller 18 which produces in line 22 a pneumatic pressure corresponding to the flow. This output pressure is recorded by a pen 40 and is also applied to the interior of a bellows 68, Fig. 2, which acts on baffle 76, the latter being supported on a spring arm 80. Bellows 68 is opposed in its action on baffle 76 by a similar bellows 70, the interior of which is subject to a datum pressure set by adjustment of an indicating arm 54, and any movement of baffle 76 due to a difference in the pressures in bellows 68, 70 will correspond to a variation in the flow in line 10 away from the set value. The pressure developed in casing 62 is applied to a pneumatic motor 32 which actuates a throttle valve 34 to keep the flow in line 10 at the set value. Bellows 72 communicate with the interior of the casing through an orifice 142 and bellows 74, through a capillary tube 144, the restrictive effect of orifice 142 being less than that of capillary tube 144. Bellows 72 imparts a derivative action to the controller and bellows 74, an integral action. On actuation of a selector lever 58, pressure fluid is applied to a diaphragm-actuated valve in the block 67 attached to casing 62 to shut off the passage leading from the interior of casing 62 to motor 32 and thus hold valve 34 in its adjusted position. Further actuation of lever 58 connects the line leading to bellows 70 to motor 32 so that the latter can be controlled manually from the datum-setting arm 54. When block 67 is removed from the casing, a spring-pressed valve closes off the end of capillary tube 144 to prevent loss of air from the motor.

Title: An explosion-relief cover for containers, pipelines and the like
Inventor: WIEMER JEAN
IPC: B01J3/00
Filed: 1971-04-19
Abstract: 1275388 Explosion relief cover MATELLGESELLSCHAFT AG 19 April 1971 [3 March 1970] 22285/71 Heading F2P The increase in pressure resulting from an explosion in a vessel is relieved by a cover 3 over a flanged aperture 2 which opens and encounters successively damping devices 9, 10, 11, of varying damping strengths, mounted on a carrier ring 5, at least one of the devices 9 being fixed to the cover 3 so as to determine the minimum internal pressure at which the cover opens. As shown, the damping devices may comprise spring-loaded telescoping tubes 9, 10, 11 arranged circumferentially on the ring 5 which is fixedly spaced from the flange 2 by bolts 4. The differing damping characteristics between each size of telescoping tube are achieved by springs 6 (7, 8) (Fig. 1, not shown) of differing compressive stress responses (Fig. 3, not shown) so that as the cover 3 encounters successive tubes equal increments in pressure build-up result in smaller displacements of the cover to prevent violent opening against stop members. The products of the explosion escape from the annular gap between the open cover and aperture flange 2. After relief of the internal pressure, rapid and possibly damaging closure of the cover is prevented by a central shock absorbing piston and cylinder assembly 13, 14 mounted on a transom (12) (Fig. 5, not shown), the rate of closure being adjustable by means of valves 21. In an alternative embodiment, the spring- loaded tubes are replaced by piston and cylinder dampers (15-18) (Fig. 6, not shown) in which the cover 3 successively encounters piston extension rods and the cylinders are mounted on the carrier ring 5. A further arrangement comprises a combination of piston and cylinder assemblies and spring-loaded telescoping tubes (Fig. 7, not shown).

Title: Improvements in or relating to taximeters
IPC: G04C1/06
Filed: 1962-06-08
Abstract: 942,977. Clockwork mechanism. KIENZLE APPARATE G. m. b. H. June 8,1962 [June 9, 1961], No. 22318/62. Heading G3T. [Also in Division G4] A clock spring in a taximeter having both time and distance drives is maintained wound up between two variable limits by an electric motor which also rotates a cam control shaft for the meter. A spring housing 35, containing a coil spring wound up through a predetermined number of turns and maintained in this condition by a pawl 47, a cooperating stop 49 on the housing and a pin 44 on an arm 45 attached to the spring core, is inserted in the apparatus and a lever 28 is moved to the right as indicated in Fig. 2 to close an electrical contact pair 30A. This operates an electrical motor 2 to drive a shaft 5 which terminates in a gear 7. A carrier, formed by a disc 12, spindles 10, 11 and 16 and a gear 9, is free to rotate relative to the shaft 5 and when held stationary by a nose 27 on the lever 28 engaging one of two recesses 25, 26 in the disc 12, causes by way of idler gears 13,14 a control shaft 17 and its terminating gear 15 to rotate in a direction opposite to the shaft 5. As rotation of the shaft 17 is resisted by a follower roller 22 spring-pressed into recesses 20 in a locking disc 19 when the lever 28 is moved to the right the carrier will rotate in a direction opposite to that of the shaft 5. This rotates the spring core and the arm 45 through one revolution (clockwise as shown in Fig. 2) by way of gears 9, 31 and 34. The pin 44 allows the pawl 47 to pivot under the action of a spring 48 so that its end 47<SP>1</SP> disengages the arm 28. On completion of this revolution the nose 27 enters the other of the two recesses 25, 26 allowing the contacts 30A to open and stop the motor which has an automatic brake. The housing 35 begins to rotate in this clockwise direction so as to commence to unwind the spring. This rotates through gears 36, 37, 39 a ratchet wheel 42 the speed of rotation being controlled by a governor 40. The ratchet wheel 42 and a ratchet wheel 43 together form a mixed time and distance drive for a lifting wheel shaft 1 to rotate a price counter in the usual manner.

Patent GB-424264-A (GB)
Title: Improvements in or relating to the production of tricarbocyanine dyes
IPC: C09B23/08
Filed: 1933-08-12
Abstract: Tricarbocyanine dyes are prepared by reactting a m -halogenated oxazole with pyridine and with a quaternary cyclic ammonium salt containing a reactive methyl group.  Or the m -halogenated oxazole is first reacted with pyridine to produce a pyridinium salt and this is reacted with a quaternary cyclic ammonium salt containing a reactive methyl group.  In either case the pyridinium salt formed by reaction with the halogenated oxazole easily undergoes fissure in the pyridine ring, thus enabling the formation of a tricarbocyanine dye to take place and yielding a m -amino-oxazole as bye-product.  Suitable oxazoles are 1-chloro- or -bromobenzoxazole or 1-chloro-naphthoxazole. Suitable quaternary cyclic ammonium salts are those derived from thiazoles, thiazolines, oxazoles, oxazolines, selenazoles, selenazolines, quinolines, indolenines, pyridines, and analogous polycyclic compounds; in such compounds the carbocyclic rings may be substituted, for example, by hydroxy, alkoxy, halogen, alkyl, aralkyl, aryl, amino, substituted amino.  A diluent such as alcohol and an acid-binding agent such as sodium, sodium acetate, piperidine, trimethylamine are preferably present.  In examples, 1-chlorbenzoxazole is reacted with pyridine and the resulting pyridine-benzoxazolyl chloride reacted with 1-methylbenzthiazole allylbromide, 1-methylbenzthiazole ethiodide and lepidine methiodide in alcohol in presence of sodium alcoholate, and with 2.3.3-trimethylindolenine methiodide in presence of acetic anhydride and sodium acetate.  In a further example quinaldine ethiodide, 1-chlorbenzoxazole and pyridine are reacted together in alcohol containing sodium alcoholate.  The Provisional Specification also relates to the use of substituted pyridines in the foregoing processes whereby dyes substituted in the tricarbocyanine chain are derived.  Specification 351,555 is referred to.

Title: Improvements in or relating to phonographs
IPC: G11B17/00
Filed: 1931-02-24
Abstract: 383,939. Magazine gramophones. SPARKSWITHINGTON CO., Jackson, Michigan, U.S.A.-(Assignees of Winchell, A. B. ; 906, Oakridge Drive, Jackson, Michigan, U.S.A.) Feb. 24, 1931, No. 22689/32. Convention date, April 26, 1930. Divided on 383,640. [Class 40 (ii).] In a magazine gramophone of the kind described in Specifications 383,640 and 383,940, wherein the motor driving the turntable operates through a clutch to effect the recordchanging operation involving a falling and rising movement of the turntable during delivery of a played record and feed of a fresh record thereto, provision is made for increasing the torque of the motor during record changing by changing the connection of its field coils from parallel to series, and the switch connections can also be controlled manually for changing a record at any time. The circuit is shown with the field coils 178, 173 of the motor 1 connected in series, for record changing, through a press-button controlled switch 79<1>, adjustable speed regulating resistance 174 and a switch 31<1> controlled by a member 29<1> on the recordchanging clutch mechanism. To start the machine from rest, or initiate a record change, a press button 79 is partially depressed and trips the clutch through which the record changing is effected, thus allowing the switch 31<1> to close during this operation, and the button is then further depressed to open the contacts 79<1> and close the contacts 80<1>, 811. During the descent and rise of the turntable whilst the record is being changed automatically, the pick-up arm now unsupported by a record completes the circuit at 161 and shortcircuits the resistance 174. When the turntable rises with a fresh record against the pick-up 41 the circuit is broken at 161 and completed at 160 which maintains the circuit through the motor with the fields connected in parallel during the playing of the record. Shortly after the circuit is completed at 160 the record-changing clutch is disengaged and through members 29<1> opens the switch 31<1> whereby the circuit for series connection of the field coils is broken. When the records are all played and the last one delivered from the turntable, the turntable in its lifting movement will not engage the stylus and the pick-up arm will not be rocked to make the contact at 160 ; the machine therefore stops.
