Title: Improvements in connection with the Feeding of Molten Glass from Furnaces and the like.
Inventor: HOWARD GEORGE EDWIN
IPC: C03B7/08
Filed: 1917-08-10
Abstract: 120,744. Howard, G. E. Aug. 10, 1917. Delivering molten metal.--Relates to the feeding of molten glass from tanks, furnaces, or other supply reservoirs to moulds &c., and consists in continuously flowing the glass through an orifice in the reservoir &c. and acting on the glass, at or after it has passed the orifice to vary the forces of suspension in the glass without checking, stopping, or reversing the flow of the glass through the orifice and separating or detaching the mass from the supply body. As shown in Fig. 1, a tube 3 is mounted within the tank 1 with its lower end projecting slightly beyond the discharge opening 2 When suction is applied to the tube, the glass is drawn up inside it, the relative diameters of the opening 2 and tube 3 being such that the suction does not stop the normal flow of the glass through the annular orifice 2'. As the globule 6 elongates, the glass in the tube 3 is forced out to fill the centre of the globule so that it assumed the form shown at 8, Fig. 3. On again applying suction, the globule contracts at 9, Fig. 4, whereupon it is cut off, the lower end or chilled portion 11, Fig. 5, being drawn up into the tube 3 so that it is incorporated in the glass flowing down and around the tube. The end of the tube may be situated within the discharge opening or slightly above the bottom of the vessel. As shown in Fig. 10, the tube is replaced by a lateral passage 12 formed in an offset 13 of the reservoir 11 and connected by a passage 14 to a source of vacuum. The passage 12 takes the glass from and adds it again to the sides of the drop. In another arrangement, Fig. 11, a lateralhorizontal passage 16 just below the opening 2 is connected by a pipe 17 to a source of vacuum.

IPC: G05D3/12
Filed: 1938-04-14
Abstract: 586,590. Light-sensitive control devices. VICKERS-ARMSTRONGS, Ltd., and INGOLDBY, M. K; April 14, 1938, No. 11587. [Class 40, (iii)] [Also in Group XXXVIII] Relates to electric correspondence control apparatus for use with guns, search-lights and sound detectors for introducing into a predictor or other calculator with amplified power movements of a pointer or controller. According to the invention, movement of the pointer &c. causes light to fall on one or the other of a pair of photo-electric cells the currents from which control a reversible electric follow-up motor, that' moves the appropriate member of the predictor &c., and also acts to restore the photo-electric devices to balanced position. Fig. 1 shows two systems operating in, series for introducing the air-speed of an aircraft, measured by a pitot tube 1 and registered by a pointer 2, into a predictor '11 for controlling anti-aircraft guns mounted on aircraft. The follow-up motor 3, controlled by a photoelectric device 2A, influenced by movement of the pointer, rotates an electric transmitter 5, connected for synchronous movement with a remote receiver 7. The receiver in turn influences a second photo-electric device 8, controlling a follow-up motor 9, actuating a. member of the predictor 11. Fig. 2 shows the photo-electric and amplifying-valve systems within a box 13, in association with the followup motor and gearing for actuating the shafts 4, 10, Fig. 1, represented by shaft 61 in Fig. 2. The follow-up motor 57 drives a shaft 59, geared to the shaft 61, and also geared to a shaft 55 coupled to a rotor within the box 13. The rotor, mounted in ball-bearings, terminates in an adjustable hollow casing 20, containing lens systems 25-26 for focussing light from a source 24 on to one or the other of photoelectric cells 27, 28 according to the masking or unmasking influence of a screen 64, connected with the controlling pointer 2. Currents from the cells 27, 28 are led to the grids of amplifying valves 77, 76, Fig. 4, the anode currents of which energize the field coils 91, 90 of the reversible follow-up motor 66.. The electrical connections for the lamp, cells and valves are made through slip rings 32 on the rotor shaft engaged by brushes 33. The valves are carried in sockets at the sides of the rotating casing 20. Specification 586,589, [Group XXIX], is referred to.

Abstract: 336,578. Alder & Mackay, Ltd., and Anderson, J. April 15, 1929. Exhibiting models; electricity, supplying by time controlled apparatus; coin action, weight.- In an electric prepayment mechanism for driving a. model, such as the wheels of a locomotive, but which may be used in connection with meters or other apparatus, a coin inserted through a slot a, Fig. 1, falls, down a shoot f into a channel i having insulated sides, where it engages the arm t, Fig. 2, of a four-armed lever o to rotate this, so that a contact m on a second arm n engages a fixed contact l to complete an electric circuit. The source of power is connected to the contacts l, m and to an electric motor 9, which drives the model and also, through worm gearing 7, 3, 5, 6, rotates a threearmed spider one arm z of which is normally vertical and another arm 1 crosses the bottom of the coin channel i. The circuit remains closed until the vertical arm of the spider engages the top of the coin and forces it past the arm t, the further movement of the lever o being permitted by a spring mounting w for the contact l. The lever o then returns by gravity to its initial position and breaks the circuit. An arm u of the lever o carries an insulated handle v for moving the lever for testing purposes, and acts as a counterweight. Testing and diverting coins.-Small coins pass through an opening g in the shoot f, and a fourth arm s of the lever o deflects to the cash box, without fouling the mechanism, a second or subsequent coin put into the slot while. the mechanism is in action.

Abstract: 494,252. Calculating - apparatus. STANDARD TELEPHONES & CABLES, Ltd. April 23, 1937, No. 11686. Convention date, May 2, 1936. [Class 106 (i)] A calculating-device for solving navigation problems comprises three coaxial relatively rotatable discs carrying scales relating respectively to geographical meridians, to magnetic meridians and to bearings obtained by radio, a cursor arm being fixed to the last-named disc and a further independent cursor arm being movable over all the discs. The disc 1 relating to geographical meridians has scales 2, 5 and an arrow (not seen) at the zero of scale 2. The disc 6 relating to magnetic meridians has scales 7, 8 and the arrow on disc 1 is set to indicate on scale 8 the magnetic declination. The cursor line 18 on the independent cursor 17 then indicates the true route on scale 2 of disc 1 and the corresponding compass course on scale 7 of disc 6. A disc 10 is set so that the bearing obtained by radio is indicated by a scale 11 on disc 10 reading against cursor line 18. The cursor 24 fixed to the disc 10 indicates the corresponding compass and true bearings on discs 6 and 1 respectively. A series of inclined lines 23 is marked on a transparent part of the cursor 17 and a set of inclined lines 15, Fig. 4, is provided on the margin of the disc 10, these latter lines leading from each radio bearing graduation 11 at an angle corresponding to a correction to be applied to that radio bearing. The disc 10 may have a second scale 12 which is used in drawing the lines 15 from given data, the scale 12 then being detached at a perforated line 13. When a radio bearing is being set on the device of Fig. 5, the disc 10 is adjusted until the graduation 11 denoting the bearing is positioned so that its inclined line 15 is beneath a line 23 of the same slope. The desired correction is thus incorporated. The back of the device has printed upon it a circularly-arranged table of coefficients, each coefficient defining the ratio of the sine of a first radio bearing to the sine of the difference between said first bearing and a second radio bearing. The Specification describes how these coefficients enable the distance from the radio transmitting station to be determined. The Specification states that the discs 6, 10 may be connected to a compass and a radio direction-finder respectively.

Title: Printing arrangement for high speed teleprinters
IPC: B41J3/54
Filed: 1961-03-30
Abstract: 909,050. Selective printing. CREED & CO. Ltd. March 30, 1961 [April 7, 1960], No. 11762/61. Class 100(4). In a high-speed printing-machine in which the print mechanism travels across the paper which is transversely fixed, the carriage-return time is eliminated by having two print heads SK1, SK2 e.g. element printers or type-wheels which travel in opposite directions. This means that while one head, say SK1, is moving in letter-space direction and forming characters in the process, the other SK2 is travelling in carriage return direction. By the time the left-hand print head has reached the centre of the paper the right-hand head has returned also to the centre and is immediately ready to form the characters for the remainder of the line when it moves left to right. When the righthand head has reached the end of the R.H. end of the line the first head SK1 is ready to print on the next succeeding line. The heads are traversed by a helically grooved shaft AW. Data is alternatively fed to either print head by an electronic control circuit which is switched over by, in the embodiment shown, a photoelectric device controlled by an apertured disc driven 180 degrees for each half-page travel of a print head. Alternatively mechaniclal magnetic or electrostatic means may be used to direct the data to the print head travelling in the letter-space direction. Line-spacing.-The paper is advanced continuously: to ensure that the line of printing is not on a slope the shaft AW is compensatingly inclined. When head SK2 reaches the end of one line the head SK1 has carriage-returned to the beginning of the line and in a position to record in the next succeeding line.

Title: Improvements in and relating to the generators of electric lighting sets for motor vehicles and the like
IPC: H02J7/14
Filed: 1922-05-03
Abstract: 203,365. Nicholas, W. J., and Roberts, P. J. W. May 3, 1922. Pole-pieces; cores; coils; exciting.-To prevent the production of high voltages and excessive currents at high speeds in a vehicle or like generator, recesses b<2>, Fig. 3, are formed in the main pole-pieces B, and auxiliary poles D are located in the recesses. The series coil E is wound to give an opposite polarity to the surrounding main pole, so that the field is weakened as the speed rises. Fig. 1. shows a circuit in normal operation, comprising a generator G having shunt and series field windings C, E, a main automatic control switch K, and an auxiliary automatic switch M, and an external circuit J. If a break occur in the battery circuit during charging, the voltage will rise, and this rise will not be wholly compensated by the winding E. The increased voltage causes a larger current to flow through the shunt coil m<2> on the switch M, and the switch closes, so that the armature is short-circuited through the coil m<1>. The series coil k<2> on the main control switch K is de-energized and the spring k' causes the switch to open, thus breaking the shunt field circuit. When the generator current ceases, switch M is opened by the spring m<3> so that the generator is again ready for operation. The shunt field is excited at starting by the battery H. The Provisional Specification describes the use of the auxiliary switch for disconnecting the battery at the peak of the charging current, and also the arrangement of the exciting windings so that change in the direction of rotation of the armature does not affect their action. Specification 191,782 is referred to.
