Filed: 1952-10-03
Abstract: 765,445. Copying-telegraphy; local copying by scanning. TIME, Inc. Oct. 3, 1952 [Oct. 18, 1951], No. 25882/55. Divided out of 765,443. Drawings to Specification. Class 40 (3). The subject-matter is included in Specification 765,443, but the claims relate to a circuit arrangement for restoring the contrast at an edge separating areas of light and dark tones and extending transversely to the direction of scanning. The circuit comprises means for differentiating an input derived from the scanning arrangement, reversing the resulting waveform which is subjected to a further differentiation, the second differentiated signal being added to an image-carrying signal to provide a signal representative of the contrast at the edge of separation. In a colour reproduction system having three colour channels corresponding to yellow, cyan and magenta and a black channel, the second differentiated signal derived from a particular channel may be added to the image-carrying signal of that channel or to that of another channel. In one arrangement the twice-differentiated image signal from the magenta channel may be employed to restore the boundary contrast in the black channel. Specification 761,535 and U.S.A. Specification 2,253,086, also are referred to.

Abstract: 160,411. Geeson, W. J. Sept. 8, 1920. Money-delivering apparatus. -Apparatus for use in connection with the changing of definite sums of money such as Treasury notes &c. comprises two sets of receptacles, one set m termed the addition-set and the other set l termed the change-set. The addition-set includes one or more rows of horizontallyarranged receptacles, and the change-set includes twice as many rows of horizontally-arranged receptacles, the number of receptacles in each of the rows being the same. The rows are preferably arranged stepwise, as shown in Fig. 3. The receptacles of the addition-set are intended for the reception of money or tokens of a denomina. tion higher than that given as change and initially located within or disposed over the receptacles of the change-set. When the apparatus is to be used for changing Treasury notes, piles of coins, each pile amounting to, say, ten shillings, are initially placed over the receptacles l of the change-set. If change is required for a 10s. Treasury note, one of the piles is handed over, and the 10s. note received in exchange is placed within the receptacle from over which the pile is taken. If a ú1 Treasury note is to be changed, two piles of coins, or one pile and a 10s. note are taken from two of the receptacles l, one of these being directly behind the other, and the ú1 note is placed in one of the receptacles m of the addition-set immediately behind the receptacles l from which the change was taken. The total amount of money in the receptacles m at any time is equal to the total amount of change which has been given from the receptacles l.

IPC: G01C5/00
Abstract: 259,760. Glauser, M. Oct. 13, 1925. Sighting-levels and clinometers.-In a surveying instrument or the like, provided with a spirit level, means are provided whereby the line of sight may be adjusted without the necessity for bringing the air bubble to the central position. As shown, the telescope a of a sighting level has arms b, c carrying a spirit level d. A prism g, through which the bubble is observed, is mounted in a member f adjustable along a slide e by a rack i, pinion j, and roughened drum k. The member f also carries a wedge engaging a lever m secured to a parallel glass plate n in the axis of the telescope. The instrument is first roughly levelled by a spirit level o, observable with the aid of a mirror p, to ensure that the bubble in the end d is free from the end of the tube, and the drum k is turned until the bubble is seen by the prism g in coincidence with an index mark. The consequent movement of the member f turns the plate n to bring the image into the position relative to the cross-wires that it would occupy if the optical axis of the telescope were itself adjusted. In a modification, the crosswire carrier may be mounted on a slide movable vertically by the wedge l.

Title: Intermediate frequency coupling systems for a superheterodyne receiver for wireless signalling
IPC: H03H7/01
Filed: 1931-11-21
Abstract: 392,411. Valve circuits for wireless reception. HAZELTINE CORPORATION, 13, Exchange Place, Jersey City, New Jersey, U.S.A.-(Assignees of Macdonald, W. A. ; Little Neck, New York, U.S.A.) Nov. 21, 1931, No. 26290/32. Convention date, Feb. 13, 1931. Divided on 391,521. [Class 40 (v).] An intermediate frequency amplifier for a superheterodyne receiver, has one intervalve transformer coupling designed to give a double resonance and one or more succeeding transformer couplings designed for single resonance, the overall response being substantially uniform over the side-band range. As shown in Fig. 1, the output from the first detector of a superheterodyne circuit, is passed to the amplifier 41 through tuned circuits 43, 44 so coupled as to give resonance peaks at the limits of the side-bands as shown by curve a of Fig. 2. The couplings 49, 55 between the valve 41 and the succeeding amplifier 42, and between that amplifier and the second detector 60, have only one coil tuned, preferably the anode coil, so giving a single resonance (curve b of Fig. 2). The combination gives a curve c of substantially uniform gain over the side-band range. The secondary coil 52 is designed to have a natural resonance at a frequency lower than the lowest received frequency. A volume control is afforded by a tapped resistance 53 across the secondary 52 of the coupling 49 ; whilst the coupling 55 is designed to step down to suit the low impedance of the detector 60. The Specification also describes the remainder of the receiving circuit disclosed in Specification 391,521 ; and an automatic volume control arrangement of the kind described in Specification 293,462, [Class 40 (v), Wireless signalling &c.], also is referred to.

Title: Improvements in and relating to electric timers
IPC: B23K11/26
Filed: 1953-09-24
Abstract: 736,661. Control systems for resistance welders; condenser arrangements. GENERAL ELECTRIC CO. Sept. 24, 1953 [Sept. 25, 1952], No. 26364/53. Class 38 (4). An electrical timing circuit, which is largely ,independent of supply voltage variations and which is particularly suitable for controlling the firing valves 6, 7 associated with resistance welding ignitrons 8, 9, comprises condensers 2, 3 which are charged with different quantities of electricity and then allowed to discharge into one another through a timing resistor 86 in a local circuit in which the voltages of the condensers are initially additive, during which period the voltage of the condenser of lesser charge, say 3, first decays to zero and subsequently builds up with reversed polarity. At some point in this period the voltage across condenser 3 becomes sufficient to block a valve 4 which then ceases to supply firing pulses to the valves 6, 7 so thus terminate the flow of welding current which was initiated by conduction of valve 4 upon charging of the condensers. Upon closure of an initiating switch 99, a valve 1, supplied from a transformer 44 and previously maintained non-conducting by negative bias obtained from a resistor 76, is fired by a pulse obtained over condenser 100, causing condenser 2 to charge over diodes 102, 104 and condenser 3 to charge over diode 103, terminal 111 of condenser going positive and so opening valve 4, which through transformer 36 annuls a holdoff bias on the firing valve 6 which subsequently conducts under the control of a voltage obtained from a phase-shifting circuit 57 and initiates flow of welding current. A winding 71 on transformer 36 applies a " turn-on " pulse to a further valve 5 which, through a transformer 47, causes firing valve 7 to trail valve 6. Valve 1 is again rendered non-conducting (and thus terminate charging of condensers 2, 3) when valve 4 conducts, by a negative pulse obtained from a winding 106 on transformer 36 and applied to condenser 100 over diode 108. Condenser 2 now commences to discharge into- and eventually reverses the polarity of -condenser 3 over timing resistor 86 and a relatively low valued resistor 89. The grid of valve 4 thus moves negatively and the valve eventually cuts-off and terminates the weld. The screens of valves 1, 4 are supplied with phase-shifted voltages which permit conduction to be initiated by the control grids only in the early portion of the supply voltage cycle. During stand-by periods, a charging circuit comprising diode 87 and resistor 88 maintains terminal 111 of condenser 3 at a negative potential to prevent conduction of valve 4. Similarly, if during a welding operation the switch 99 is released, negative bias is immediately applied to valve 4 over diode 109 to terminate conduction. The excitation arrangements for the firing-valves 6, 7 are as disclosed in Specification 659,996. A potentiometer 98 controls the relative voltages to which the condensers 2, 3 are charged and allows the use of condensers of equal capacity.

Title: Improvements in or relating to aircraft control
IPC: B64C13/00
Filed: 1945-10-10
Abstract: 599,656. Controlling aircraft. CURTISS-WRIGHT CORPORATION. Oct. 10, 1945. No. 26421. Convention date, Dec. 6, 1944. [Class 4] A statically unbalanced control surface for controlling the motion of an aircraft about its lateral axis comprises a pair of auxiliary aerofoils disposed at the trailing edge of the surface and means tending to deflect one of the auxiliary aerofoils angularly with respect to the other. The invention is shown applied to the elevators of an aeroplane, one of which 18 carries a trimming tab 24, and the other 19 a " stability" tab 25 capable under certain conditions of flight of movement relatively to the tab 24. The trim tab 24 is operated by rigid links 27, 30, pivotally connected at a point 28, near the axis of rotation 20 of the elevator, to link 31, the lower end 32 of which is mounted on the lower surface of the elevator. The control system for the stability tab 25 comprises rigid and telescopic links 37, 40, pivotally connected at a point 38 located above the axis of rotation 21 of the elevator 19. As shown in Fig. 4 the telescopic link 40 may comprise interfitting tubes 43, 44, drawn together by a tension spring 49, or as in Fig. 5 may consist of telescopic tubes 53, 54, held in abutment by weights 59. Under static conditions with the elevators set at neutral, the trim tab 24 is set at a small positive incidence and the stability tab is maintained by the telescopic link 40 at an equal negative incidence. The arrangement is such that at low airspeeds and during take-off and landing the aerodynamic load on the tab 25 is insufficient to extend the telescopic link 40, the effects of the two tabs thus neutralising each other. For flight under forward centre of gravity conditions both tabs may be trimmed downwardly, the aerodynamic load on the tab 25 under these conditions serving to hold it rigid against the stop in the link 40. When the aircraft is flying at high speed with rearward centre of gravity the elevators and trim tab 24 are set in the neutral position, and under these conditions the aerodynamic load on. the stability tab 25 overcomes the effect of the spring 49 or balance weights 59. The tab thus floats in an approximately neutral position, and movement of the elevators in accordance with airspeed is effected automatically without adjustment of the trim tab 24. When the elevators are moved upwardly the stability tab 25 is moved downwardly with respect thereto without operation of the control link 40, owing to the offsetting of the pivotal point 38 with respect to the elevator hinge 21. The tab 24 may be given a combined trimming and balancing action by also offsetting the pivotal connecting point 28 of the links 27, 30, with respect to the hinge 20 of the elevator 18. Balance weights 66, 67, are attached to horns 68, 69, on the tabs 24, 25, respectively. Under certain conditions the operation of the controls may be improved by incorporating both the spring and weight control members shown in Figs. 4 and 5 in the operating member 40 for the stability tab 25.

In an electrostatic printer in which clouds of ions are displaced towards a dielectric web 10 through symbol-denoting apertures 18 in an endless screen travelling across the printing line, the screen is maintained in accurate spaced relationship with the web 10 by means of an air bearing. The air bearing is attached to the electrode blocks 16 and comprises a support plate 32, Fig. 3, to which are attached upper and lower plates 40, 44, clamp plates 42, 45 and spacer shim plates 41, 46 each of five thou. thickness. The lead-in to the slot is chamfered, Fig. 4, not shown, and the stencil, which is formed of stainless steel and of three thou. thickness, draws in a cushion of air on each side of it as it moves across the electrodes 16 and is constantly spaced from the web 10. In a modification the stencil guide plates may have air spaces to which air is added under pressure, Fig. 5, not shown. The stencil, the stencil drive pulleys and the guide means may be wholly enclosed and fed with filtered air to obviate blockage of the apertures 18 in the stencil by dust. The pulleys 21, 22 driving the stencil are curved in shape and this is formed by three flat areas 90, 91, 92, see Fig. 8. One pulley is spring tensioned to keep the stencil tight. Web tensioning, platen construction.-Flutter of the web 10 is obviated by reducing air pressure at the printing position by means of a pipe 19 coupled to a bore in a line-length anvil or platen 13.
