Title: Arc Discharge Lamp for the Generation of a High Intensity Ultraviolet Radiation
Inventor: VOLKER WINFRIED
IPC: H01J61/28
Filed: 1968-04-01
Abstract: 1,166,206. Discharge lamps. ORIGINAL HANAU QUARZLAMPEN G.m.b.H. 1 April, 1968 [12 April, 1967], No. 15666/68. Heading H1D. A discharge lamp has two electrodes 12, 42 for the generation of a plasma arc which emits high intensity ultra-violet radiation, liquid metal, e.g. mercury, being injected under pressure through one of the electrodes 12 into the discharge chamber so as to raise the density in the core of the plasma arc above that existing in the remainder of the lamp easing. The mercury enters through aperture 24 and passes via a pipe 20 to a tungsten tip 18 having a capillary 12 for increasing the velocity of the mercury and a protective recess 14 to prevent the end of the capillary from being closed by fusion. The pipe 20 and tip 18 are surrounded by a water cooling jacket 56. An arched insulating cap 30 deflects the water into chamber 32. A gap 60, e.g. of 0.1 mm., allows condensed mercury and mercury vapour to leave the discharge chamber 54 and to enter chamber 32, the mixture of water and mercury exiting through pipe 62, the mercury being separated and recirculated. Electrode 42 is cooled by water issuing from pipe 44, the lower end of pipe 44 having serrations which increase turbulence to improve cooling. A quartz window 46 closes the discharge chamber; in a further embodiment, Fig. 4 (not shown) an extension tube is used to permit the quartz window to be located at a greater distance from the arc, the inner surface of the window being washed and cooled by water to remove contamination from its surface. The internal surface of the lamp casing is spherical and highly polished; it may be coated with a layer which forms an amalgam which permits a high degree of reflection to be maintained.

Title: Apparatus for connecting in parallel a power supply and a static inverter and a logic device for use in the apparatus
IPC: H02J3/38
Filed: 1974-04-09
Abstract: 1430489 Electricity supply arrangements COMPAGNIE GENERALE D'ELECTRONIQUE INDUSTRIELLE LEPAUTE 9 April 1974 [9 April 1973] 15760/74 Heading H2H A logic device for controlling the connection of a static inverter 10 and a power source 20 to a load 15 comprises a first coincidence gate 44 having an input V R  responsive to a device (not shown) for checking the voltage and frequency of the power source 10, a second input R for receiving an order for coupling power source 10 to load 15 and a further input for a locking device 51, 52 which blocks gate 44 if the power source 20 is absorbing power from the inverter 10. Gate 44 feeds an anteriority detector 61, 62 which responds to the first signal either from gate 44 or from an input M for an order to connect inverter 10 to load 15 and thus feeds a signal S M  or S R  to close contacts 8 or 9 and thus connect one of devices 10 or 20 to the load 15. A second coincidence gate 48 is responsive to the coincidence of orders to connect both inverter 10 and power source 20 to load 15 and also of the output T of a device for checking coincidence of voltage of inverter 10 and power source 20. Gate 48 starts a timer 69 ... 74 which emits an output after a predetermined time to order selector circuits 81, 82 which provide an output on S M  or S R  to close the other of contacts 8 or 9. The device also includes a third coincidence gate 99 responsive to the position of contacts 8 and 9 and which provides an output to inhibit a fourth gate 94 which responds to orders M and R initially and provides a signal A V  for starting controllers 25 and 30 which maintain the frequency and voltage of inverter 10 equal to that of the power source 20. When both contacts 8 and 9 are closed, gate 99 provides a signal A I  to replace voltage controller 30 by a current controller 35. As described, the inverter 10 comprises a master clock 5, the frequency of which is controlled by a signal 6 and feeds a pilot circuit 4 which provides pulse width modulated firing pulses for controlled rectifiers in a switching circuit 2. A sine filter 3 is included. The controller 35 may allow the inverter 10 to provide a constant fraction of the load current.

Title: Article handling devices
IPC: B65B25/06
Filed: 1971-05-19
Abstract: 1356153 Delivering articles, at set intervals, for packaging; roller conveyers UNILEVER Ltd 19 May 1971 [20 May 1970] 15762/71 Headings B8A and B8C A device for handling articles comprises a plurality of individually driven rollers 3-9 arranged as a roller conveyer-scanning means 12-18 for determining the position of an article on said rollers,-means for the supply of a continuous web 21 of packing material into the path of an article as it leaves said roller conveyer, means 11 for optically scanning said web for a synchronous mark, and means for changing the speed of a set of the rollers at the discharge end of the conveyer between a higher speed and a lower speed corresponding to the speed of said web, the rollers being actuated to convey each article at said higher speed until the article is jointly supported by said set of rollers, and subsequently when, in dependence on indications from the web scanning means, the web and article are in a synchronized speed relationship, said set of rollers at the discharge end is actuated to convey at said lower speed, after which the speeds of said set of the rollers are changed back to the higher speed to receive a further article. A stack, e.g. of cheese slices 2, is fed from a conveyer 10 on to the rollers 3-9 which are all driven at the higher speed until the leading edge of the stack 1 reaches the scanning device 12, whereupon, depending upon whether, or not, a synchronous mark on the printed material 21 has reached a light scanning device 11, the rollers 3-6 are either slowed down to the lower speed, or stopped. If the rollers 3-6 are slowed down their continued movement transfers the stack on to the material 21 which is travelling at the same speed. However, if the rollers 3-6 have been stopped, they are only restarted to rotate at the lower speed for transfer of the stack on to the material 21 when the synchronizing mark on the latter reaches the scanning device 11. The rollers 3-6 are successively changed to rotate at the higher speed as the trailing edge of the stack 1 discontinues to obturate respectively the scanning devices 5-12 so that the next stack 2 is quickly transported up to the scanning device 12. The belt 10 can be replaced by a number of short conveyer belts upstream of the roller conveyer 3-9 each short conveyer belt running at the higher speed and being stopped when the following short belt is still occupied.
Patent GB-157824-A (GB)
Abstract: 157,824. Remington Arms Union Metallic Cartridge Co., Inc., (Assignees of Fuller, F. L.). Nov. 19, 1918, [Convention date]. Web-feeding arrangements; line-spacing mechanism.-A cash-register, for example that described in Specification 135,465, is provided with means for printing items and totals on a record strip fed and disposed so that entries against the last printed item may be made autographically. The record-strip is drawn from a supply roll 418 and passes around guide-rolls 423, 431<1>, a platen 410 and a guide-roll 424 to a winding-on roll 417. The last two rolls and a roll 422 are mounted on a lever 420 pivoted on the spindle 419 of the roll 417. A lever 432 on a shaft 430 is rocked by a cam 429 on the main shaft 106 and through a notch and pin 435 oscillates the lever 420, so that on the down stroke of the keys the record strip is shifted in a backward direction to bring the printing line from above the platen to below it in position to be forced against the type-wheels by the descent of the platen. On the return stroke in addition to the restoration of the strip, the slack produced by the unwinding of the strip from the supply roll due to the displacement of the roll 422 is taken up by a ratchet mechanism applied to the winding-on roll, thus effecting the forward step for line-spacing. The lever 420 with the supply and winding-on rolls and also a hand-lever 463 for giving a separate feed to the strip when desired are mounted on a U-shaped frame which can be turned up about an axis 415 to give access for replacement of the spools. Platen-impression arrangements. - The platen 410 is mounted on a pivot 406 and is provided with a tail 411 adapted to be struck for impression by a hammer 445 pivoted at 444 and operated by a spring 447. The platen is restored to position by a spring 458 and is rigidly secured for writing purposes by engagement of the tail extension 476 with an ear 439 on a lever 437, fixed on the shaft 430. When this lever rocks, a nose 441 engages a trip pawl 450 pivoted on the hammer and so depresses the latter until the nose leaves the pawl, whereupon the hammer is forced up by the spring 447, the platen meanwhile having been released by the passage of the ear 439 beyond the extension 476. Totals from the clerks' totalizers are printed by drawing forward either the lever 437 for the A clerk or the arm 440 for the B clerk. Either manipulation rocks the whole of the recording-apparatus about the shaft 105 and positions the platen above the corresponding clerk's totalizer. The stud 442 on the lever 437 meanwhile enters one or other of two stationary eccentric grooves 494, 495 and depresses and finally releases the hammer, so that the total is printed on the strip. Ink-ribbon mechanism.-The ink-ribbon 480 is supplied with ink from a pad-covered spool 481, Fig. 3, and is moved intermittingly by a pawl 488 carried by a rocking bell-crank lever 489.

Title: Improvements in selective and anti-parasitic receiving systems for electro-magnetic waves and electric currents of constant frequency
IPC: H03G11/04
Filed: 1923-06-19
Abstract: 212,177. Marrec, Ltd., and Marrec, Y. June 19, 1923. Atmospherics, eliminating or limiting; thermionic amplifiers; relaying or repeating systems; multiplex signalling; controlling aircraft &c.- Relates to selective receiving systems of the type described in Specification 185,397 in which interference is eliminated by passing the received energy, after rectification, into a series of valve circuits sufficiently aperiodic to act as amplifiers and at the same time to be the seat of sustained oscillations of a definite frequency different from that of the signal to be received. The local frequency is superposed upon the desired and undesired signals and the resulting currents are passed through a second series of low-frequency circuits tuned to the note corresponding to the resultant desired signal frequency which therefore passes through to the telephones whilst the undesired signal note is filtered out. According to the invention, (1) the plate saturation current of the aperiodic circuits is reduced by adjusting the heating rheostat h to a value where the circuits function simultaneously as generators of sustained oscillations and as limited amplifiers; (2) the rheostats m of the resonance amplifiers are adjusted so as to limit the plate saturation current and consequently the degree of amplification whilst at the same time obtaining the desired selection; (3) the heating and high-tension batteries of the interference eliminating apparatus are kept entirely separate from those used in the receiving apparatus proper; (4) the positive terminal of the high-tension battery is earthed at O. The resonance transformers j have a stepup ratio of three to one, the secondary windings being in two separate equal portions one on each side of the primary. The local oscillations may be supplied by a separate low-frequency heterodyne. The eliminator-receiver may be used in conjunction with a chain of low-powered relay stations as an economical substitute for highpowered long-range transmission, with the additional advantage of securing an effective directional result by working in series over successive small radii. It can also be utilized in combination with a second receiver, tuned to the spacing wave-length, to identify parasitical disturbances and so improve the accuracy of automatic tape-recorders. In multiplex systems it enables an accurate separation of the various frequencies involved. As a telemechanical relay for the distant control of aeroplanes, motor-boats, &c. it serves to render the control system immune from the influence of atmospheric disturbances &c.
