Abstract: 358,433. Television. MALONEY, P. E., 9. Main Street, Dundrum, Co. Dublin. July 2, 1930, No. 20050. [Class 40 (iii).] Two or more zones Z3, Z<9>, Fig. 10, of a rotating scanning member D with apertures on a spiral or helical curve, are simultaneously employed for transmitting or receiving a single object O, or two or more of the zones Z<1>, Z<2>, Fig. 3, not near opposite ends of a diameter, are used for transmitting and receiving, to obtain duplex working. The rotating member may be in the form of a drum, Fig 2 (not shown). An object O is scanned by the zone Z<1> of the disc D and the corresponding image I is synthesized by the zone Z<1> of the disc D<1>. An object O<1> is simultaneously scanned and its image I<1> synthesized by the zones Z<2>. According to modifications : reversal of the images is prevented by turning the disc D<1> back to front as compared with the disc D, Fig. 4 (not shown); to obtain correct inclination of the image to the vertical the positions of the light-sensitive cell L and the variable light source E are interchanged by pivoting them about an intermediate axis, Fig. 5 (not shown), by using one cell and two light sources and moving them circumferentially, Fig. 6 (not shown), or by optical means, Fig. 7 (not shown) ; the light source is on the same side of the scanning disc as the observer, Fig. 8 (not shown). Stereoscopic reproduction is obtained by using two zones to scan two views of the object, Fig. 9 (not shown). For colour reproduction coloured filters, or cells sensitive to, and sources emitting, single colours are employed in conjunction with a plurality of zones. To transmit two areas of the object 0 simultaneously, the light from the object is divided by mirrors 10, 11 to opposite zones Z<3>, Z<9> and reconverted into one beam at the receiver by similar mirrors. According to modifications : the whole area of revolution of the disc is used, Fig. 11 (not shown) ; one zone is used for monitoring, Fig. 12 (not shown).

Title: Improvements in or relating to hose pipes and methods of and apparatus for making same
IPC: B29C35/02
Filed: 1930-07-03
Abstract: 364,132. Hose pipes. GOODRICH CO., B. F., 37, West 60th Street, New York, U.S.A.-(Assignees of Cadden, C. C.; 439, Aqueduct Street, Akron, Ohio, U.S.A.) July 3, 1930, No. 20206. Convention date, July 26, 1929. [Class 99 (ii).] A method of making a hose pipe consists in wrapping a single strip of fabric spirally upon a rubber tube by feeding the tube longitudinally while rotating it on its own axis, the twist imparted to the hose during wrapping being nullified by twisting in the opposite direction before or after the wrapping operation or both before and after the operation. The wrapped hose is vulcanized in a mould under internal fluid pressure, the hose being preferably filled with compressed air before wrapping and sheathed with lead after wrapping, the lead sheath being removed after vulcanizing. In the wrapping apparatus of which Figs. 1A and 1B are plan views of the discharge and feeding ends respectively, endless belts 10, 11 are disposed at an angle to each other, and the rubber tube 12 is fed between the belts and along the bisecting line of said angle, so that the tube is rotated, and is wrapped by a strip of fabric 13 which is carried by the lower belt 11. The tube 12 is fed from a turntable 21 over a waisted roller 32 and a series of inclined idler rollers 34 through a guide bracket 35 to the belts. The belts are pressed on to the tube by longitudinal rails, the upper rail 16 being hinged at several points 17 to arms on transverse shafts 19 so that the rail 16 may be adjusted to allow for the increasing size of the hose. The wrapped hose is led over an overspeed pulley 47 on to a turntable 41. The hose is drawn from and returned to the turntables 21, 41 at an angle to the plane of the tables to impart a twist to the hose opposite to that received at the wrapping position. Fabric interwound with a liner 61 is drawn from a stock roll 60 over a liner-rewinding roll 68 by a pull-off roll 62 and passes to the belt 11 over rollers 72 .. 77. A reserve loop 71 has a floating roller 81 mounted in guides 83 and having a contact shoe 84 adapted to operate automatic stop devices when the loop becomes too long or too short. The arm 80 of a tension roll 79 may also actuate a stop device 91. Adhesive solution is applied to one side of the fabric from a container 88. The belts are driven by a motor 22 which also drives a shaft 24 from which the turntables and pull-off roller 60 are driven through variable-speed gear 29, 43, 64.

Title: Improvements in or relating to self-filling devices for fountain pens
IPC: B43K5/04
Filed: 1948-07-29
Abstract: 644,246. Fountain pens. COMPAGNIE DES ENCRES. July 29, 1948, No. 20246. Convention date, Nov. 19, 1947. [Class 146 (iii)] In a self-filling device for a fountain pen provided with a collapsable sac compressed by a pressure bar 3 secured to and controlled by a flexible strip and the end 7 of which is accommodated in a bore 8 of a plunger 9, the plunger has a portion 11 on which is screwed a cap 19, and the rear end of the pen barrel 1 is secured to a member 12 provided with a square guiding surface to guide the plunger 9 during longitudinal movement and prevent it from rotating when the cap 19, which is prevented from moving axially, is rotated. The member 12 carries a retaining flange 17 at one end, and has slits 18 to allow the flange 17 to spring into an annular recess 23, while the other end has a flange 14. The cap 19 is thus prevented from moving axially by the flanges 17 and 14. Rotation of the cap 19 causes an axial movement of the plunger 9 in a forward or rearward direction to deform, or allow straightening of, the strip 4. The cap 19 may be made of synthetic resinous material, in which case it is fitted with a metal bush 21.

Abstract: 429,075. Discharge rectifiers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEI-. LAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. July 10, 1934, No. 20264. Convention date, Aug. 7, 1933. [Class 39 (i)] In a gas-filled rectifier wherein the crest voltage between an anode and the incandescent oxide - coated cathode is at least 250 volts, the filling consists of mercury vapour and either argon or neon, the pressure limits for the argon being between 0À5 mm. and 0À01 mm. of mercury and for neon 1 mm. and 0À02 mm. ; the vapour pressure for the mercury during operation should be equal to the gas pressure. The anodes are of graphite preferably polished or of metal coated with graphite ; or coatings of chromium or chromium oxide may be used. In one form of three phase rectifier, the anodes 13, Fig. 1, are in small chambers 10, 11 at the sides of the main tube 2; the leads 15 supporting the anodes and the cathode leads 3 are encased in steatite tubes. Metal connection tubes 18 may be given a potential so that ignition to each anode is ensured ; a control voltage may also be applied. In a modification the three anodes 21, Fig. 3, are contained in a cylinder 33 with partition walls 34, Fig. 4; parts of the walls of the cylinder are formed of gauze 37 to allow heat induction. Each anode 21 has a bore 30 at the point where it abuts the steatite tube 26, to prevent a glow discharge at this point. A lead 38 is provided whereby the cylinder may be given any potential. A screen 45 surrounds the cathode and this screen may be connected to one of the cathode leads 43. A mica plate 40 prevents overheating of the leads at their points of entry to the tube.

Title: Indicator device for vertical-landing aircraft
Inventor: DESCHAMPS JACQUES DESIRE
IPC: G05D1/06
Filed: 1961-06-07
Abstract: 965,276. Electric analogue calculating. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. June 7,1961 [June 9, 1960; Feb. 7, 1961], No. 20532/61. Heading G4G. [Also in Division B7] In a vertical landing aircraft, the measured values of altitude h rate of climb v, and vertical acceleration γ t , and the assumed values of the maximum lift engine thrust P and total mass m are used to compute the values of the following variables by electric anologue means:- (a) the maximum vertical acceleration obtainable, given by γ m  = P/m-g, where g is the acceleration due to gravity; (b) the vertical acceleration γ, required to achieve touch down at zero rate of descent, given by γ1 = v<SP>2</SP>/2h; (c) the altitude h (γt) at which # would become zero if the instantaneous acceleration γt were maintained, given by h (γt) = - #<SP>2</SP>/2γt + h (d) the altitude h (γ m ) at which v would become zero if the maximum acceleration γ m  were attained and maintained, given by h (γ m ) = v<SP>2</SP>/2γ m  + h and (e) the time interval t after which h (γ m ) will no longer be positive if the instantaneous acceleration γt is maintained. A square generator supplies a signal representing v<SP>2</SP> from an input representing v,when required, and where division is necessary, it is performed as in Fig. 6. In this Figure the maximum available lift engine thrust P is computed in a device 17,from inputs representing the nominal maximum thrust, ambient temperature and pressure, and v. The output representing P is fed as one input to a high gain amplifier 19. The total mass m is computed from the take-off mass,fuel consumed, and mass of articles dropped in an amplifier 20a, the output of which forms one input of a multiplier 18. The other multiplier input is the output of amplifier 19. The high gain of the amplifier requires that the total input be very small, and thus the output is P/m = γ m  + g. A signal representing -g is added in amplifier 20, to derive γ m . Other additions, multiplications, and divisions are affected similarly, except that the term v<SP>2</SP>/2γ m  required for h (γ m ) is derived by controlling a potentiometer, energized by a signal representing #<SP>2</SP>,by a device computing ¢ γ m . An explicit formula for t is given, but it is computed as shown in Fig. 7, where an electronic switch feeds a sampled value of γ t  to two integrators in series, which have simultaneously sampled values of v and h as initial values for the integrations, to produce outputs v (#) and h (#) where # is "accelerated" time. v<SP>2</SP>(#) is generated from #(#), and divided by 2γ m , and the result subtracted from h (#), to give h (γ m ) (#), the predicted value of h (γ m ), and the value of # is registered when h (γ m ) goes negative. This computation is repeated, say, 50 times per second,fresh samples of γ t , v, and b, being taken for each computation.

Abstract: 336,559. Crowther, F. K., and British Talking Pictures, Ltd. July 4, 1929. Records, optical and combined phonographic and kinematographic; duplicating; sound grooves and traces.-A photographic sound record having a part which is faded or is a mixture of two sound records is made by removing a part of a record and substituting in its place another record of the desired characteristics and which is made by the use of. the part of the original record that it replaces. The portion of a record 1 to be faded is passed through a reproducer 2, the output of which passes through a volumecontrol device 3 and amplifiers 4, 5, to a recorder 6. During the recording on the film 7 of the recorder 6, the control 3 is actuated to produce a record on the film 7 of the desired characteristics. An indicator 8 and monitoring loud speaker 9 may be used so that the nature of the record on the film 7 may be ascertained during. the recording process. The record 7 is then substituted in the original record 1 in place of the part to which it corresponds. To record on the film 7 a mixture of two records, the output from a second reproducer 10 is also passed through the members 3 - - 6. In a modification, the portion of a record to be faded is printed, an adjustable mask being used so that the resulting record is of tapered shape 14, Fig. 2. This record 14 is then substituted in the original record. A mixed record 20, Fig. 4, in which one record is faded while a second record is augmented may be printed from two original records, the record 20 then being inserted on the carrier of one of the original records in place of the corresponding passage. A record made according to the invention may be combined with a kinematographic picture film.

Abstract: 1437981 Multipliers and dividers RICOH KK 1 May 1973 [1 May 1972] 20622/73 Heading G4G An arithmetic circuit comprises resistances connected in two parallel circuits each having a constant current source, the first circuit providing a source of constant voltage for application to the second. As shown, R ZD , ZD and Tr 1  maintain a constant voltage across R 1  whereby these elements together provide a constant current through R 2  The circuit R 1 , R 2 , Tr 1  together with Tr 2  provides a constant voltage across R 3  Hence a constant current is maintained through R 0 , so that: E 0 #(R 2 .R 0 )/ (R 1 .R 3 ).E 1 . By varying some of these resistances and keeping others constant various division and multiplication operations may be performed. In the modification of Fig. 2, the accuracy of the circuit is improved by supplementing the transistors Tr 1 , Tr 2  by differential amplifier circuits of unit gain, respectively A1, Tr 1 <SP>1</SP> and A2, Tr 2 1. In a practical version of the circuit (Fig. 4, not shown), the resistances R 2 , R 3  are variable and are constituted by D/A converters in which input quantities A and B are entered. An analogue voltage representing A/B is derived as the output of amplifier A3 and is applied to one terminal of a comparator the other output of which is connected to a D/A converter. The latter is connected to a counter driven by a clock-pulse source which is turned off when the inputs to the comparator become equal. The contents of the counter then indicate A/B.

Title: Apparatus for rhythmically modulating electrical oscillations produced by thermionicvalves
IPC: H03C1/20
Filed: 1920-07-10
Abstract: 148,801. Huth Ges., Dr. E. F., and K³hn, L. April 3, 1919, [Convention date]. Wireless telegraphy and telephony.- Oscillations produced by a thermionic valve are modulated in accordance with the signals to be transmitted by varying the impedance of a shunt across the valve. The impedance shunt may comprise an auxiliary valve with its grid potential controlled by a microphone, and it is connected directly across the plate and filament of the oscillating valve or across the inductance of its output circuit. In the apparatus shown in Fig. 2, the plate circuit of the generating-valve r includes a portion of the aerial inductance and the battery e shunted by a condenser. A tuned grid circuit t is also provided. The impedance shunt may be an ohmic resistance, but, as shown, comprises a valve b with its plate a and filament k connected to the plate and filament of the oscillator, and with its grid connected, preferably through a transformer, to a microphone circuit. A variable amount of energy is thus diverted from the aerial and the emitted waves are modulated in amplitude in accordance with the signals. A choke coil d may be placed in the leads of the source q. The grid g of the tube b has a suitable normal voltage, say of 30 volts. The connexion from the plate a may be made to a point on the aerial inductance beyond the point of connexion of the plate of the oscillatory valve r. The Specification as open to inspection under Sect. 91 (3) (a) refers to a modification shown in Fig. 6 (Cancelled), in which the plate battery q of the generating valve is connected across a condenser k1, and the control impedance comprises a valve b connected across the battery q. In this from the condenser k<1> forms a short circuit for the oscillatory current, but modulation is effected owing to the valve b forming a variable shunt path for the direct current supplied from the source q. This subject-matter does not appear in the Specification as accepted, but is the subject of a divided application 170,013.

Example 1 describes a system comprising a first sheet of paper coated with microcapsules containing Crystal Violet lactone dissolved in tri-n-butyl phosphate and a second sheet coated with attapulgite, starch and a dyestuff of the formula  When the first sheet is placed, treated side lowermost, over the second sheet, treated side uppermost, and the top side of the oversheet is written upon, a copy of the script appears in a violet-black colour on the top side of the receiving sheet. Benzoyl lenco-methylene blue may be used instead of, or together with, Crystal Violet lactone (Examples 2 and 3). Example 4 describes a system in which the oversheet is identical to that used in Example 1, but the receiving sheet is coated with a composition containing the dyestuff an acid phenolic resin, titanium dioxide, a condensation product of formaldehyde and naphthalenesulphonic acid, starch, and a butadiene latex. Example 5 describes a system comprising a single sheet of paper coated with the microcapsules of Example 1 and the coating composition applied to the second sheet referred to in that Example. When a paper sheet is placed over the treated sheet and written upon, a copy of the script in a violetblack colour is produced on the treated sheet. Example 6 relates to a system comprising a paper coated with (a) sodium alginate and an etherified methylolmelamine to improve "solvent hold out," (b) a starch-containing dispersion of a polymetaphosphate and C.I. Solvent Black 1, and (c) an aqueous dispersion of a melamine formaldehyde resin, polyvinyl alcohol, and an acid phenolic resin, and a microcapsule coated sheet as described in Example 1. Example 7 relates to a system comprising the microcapsule-coated sheet of Example 1 and a paper in which the solvent dyestuff-1- methylamino-4-(m-toluidino)-anthraquinone is incorporated in the paper, the paper being coated with an attapulgite-starch composition. The carrier materials may be films of organic polymeric materials, metal foils, or fibrous fleeces. Malachite green lactone, and its ethyl and propyl homologues may also be used as the chromogenic substance. Many suitable colour developers are named.
