Title: Apparatus for measuring the thickness of non-magnetic layers on a magnetic base material
IPC: G01B7/06
Filed: 1955-08-16
Abstract: 799,768. Measuring thickness. BINKO, J., BRUNA, V., and SEVCIK, J. Aug. 16, 1955 [Oct. 13, 1954], No. 23584/55. Class 37. Relates to devices for measuring the thickness of non-magnetic layers on magnetic base materials and to such devices wherein the extension of a spring necessary to detach a magnet from a point of contact with the test material indicates coating thickness. In the Figure, rotating a sleeve 9 moves pin 7 along grooves 8 in gauge body 1 so as to extend spring 4 from suspension roller 6 and eventually detach bar magnet 2 from the test coating. A transparent coloured indicator 13 rigidly connected to pin 7 dovetails into groove 14 along outer surface of gauge body 1 and the point of pull-off of magnet 2 is shown by the position of indicator 13 in relation to a coloured scale 15 along the bottom of groove 14. The link 3 between spring 4 and magnet 2 has areas of different colours and the borderline between the two colours disappears at moment of pull off when measuring substantial thicknesses. A sleeve protects the apparatus when not in use.

Abstract: 1,245,673. Gas turbine by-pass jet engines. MOTOREN-UND TURBINEN-UNION MUNCHEN G.m.b.H. May 8, 1969 [May 8, 1968], No.23611/69. Heading F1J. The invention relates to a gas turbine jet engine of the by-pass type comprising reheat equipment, in which the exhaust gas flow and the by-pass air flow are mixed before discharge through the propulsion nozzle, there being hollow diffuser blades downstream of the turbine, the blades being open or openable at the trailing edge, the by-pass air flow passing at least in part into the diffuser blades and out through the open trailing edges thereof. In the engine shown the HP and LP turbines are shown at 5 and 6 and the by-pass air duct at 32. Hollow diffuser blades 12 are disposed downstream of the LP turbine and extend between the casing 14 and the exhaust cone 13, the blades being open at their radially outer ends to the by-pass duct, also at their downstream ends so that by-pass air flows in through the blades and out through their trailing edges into the exhaust gas stream. Deflector vanes 23 are provided to guide the by-pass air into the blades 12, a portion of the air passing straight to the reheat section as indicated by the flow arrow. Fuel injectors 18 having discharge orifices 19 opening through the leading edges of the blades are disposed within the blades, the fuel discharging in an upstream direction as indicated by the flow arrows 21. Flame stabilizers may be provided extending between adjacent blades 12. In Fig.6 openings 26 are formed in the side walls of the hollow blades 25 for the inflow of turbine exhaust gases. The deflector vanes 31 in this embodiment are located wholly within the by-pass duct 32, and the fuel injectors 27 discharge fuel in a downstream direction. Flame stabilizers 29 are disposed downstream of each hollow blade 25. In Fig.8 the side walls of each hollow blade are pivotally mounted on a pin member so that the blades may be disposed either in the open position shown in full lines or in the closed position shown in broken lines. The side walls are movable by means of a pair of actuating rings 39, 41 and links 43, 44. The pivot pins may constitute the fuel injector.

Patent GB-818583-A (GB)
Title: Making and packaging flat or tubular film in reel form
IPC: B29C48/10
Filed: 1955-08-17
Abstract: In the production of films by extruding thermoplastic material through an annular orifice of uniform width, inflating the tubular film by introducing into it a gas at superatmospheric pressure, collapsing the film, and thereafter rolling up longitudinally the collapsed or flattened tubular film or flat film cut therefrom, the entire extruder, including the means for melting the plastic and forcing it under pressure to the extruder head, is rotated about the extrusion axis whilst the collapsed film is restrained against rotation, the extent of the rotation of the extruder in one direction before any reversal in the direction of rotation being such that all irregularities in thickness are distributed across the entire width of the rolled final product in successive convolutions thereof.  As shown, one end of the extruder 1 is mounted on the circular track 2, wth the other end centred on the pivot bearing 3 and holding the extrusion die head 4 constantly centred above it.  The wheels 6 support the outer end of the extruder on the track.  The thermoplastic material in particulate form is fed to the extruder through the hopper 8.  The motor and other equipment for operating the extruder are enclosed in the housing 9.  The drive motor 11, through the speed reduction gear 12, rotates the drive pinion 14 which cooperates with the circular rack 15 on the circular track, causing the pinion to traverse the track and so rotate the entire extruder about the extrusion axis.  The direction of rotation of the extruder is reversed after it has rotated <PICT:0818583/IV (a)/1> through nearly 360 degrees by means of a cam which is mounted on the circular rack 15 and actuates a reversing switch.  The extruder and its accessories are mounted on the platform 17.  The die head includes means (not shown) for inflating the extruded tubular film 22 and thus stretching the film laterally.  The tubular film 22 is gradually collapsed by rollers 24 and finally collapsed by rollers 26 urged together by pressure cylinder 25. The collapsed film 32, after leaving the rollers 26, passes over cooling drums 30, supported on the frame 31, which also supports the trimming knives 35 which trim the folded edges from the flattened tubular film with formation of two separate flat films 321, 3211, which are collected on the wind-up rolls 32a, 32b respectively.  Alternatively, the collapsed tubular film may be wound directly on the wind-up roll 36 without being trimmed.

Abstract: 1515705 Division apparatus FUJITSU Ltd 30 May 1975 [31 May 1974] 23700/75 Heading G4A In apparatus for preparing division of 2N-bit numbers using circuitry designed for N-bit numbers, the error arising in the calculation of the N most significant bits of the result is ascertained and in the calculation of the N least significant bits adjustment is made in dependence on the ascertained error. As described the division function (A, B, C and D being N-bit number) is derived by calculating to which it approximates. The calculation is described with reference to the flow drawing of Figs. 4A-D. Numbers A and C are entered into registers D, M and <SP>1</SP>/ A  is calculated by multiplying A by successive numbers R 0 , R 1 , R 2  so that R 0 R 1 R 2  then approximates to <SP>1</SP>/ A  but is inaccurate in the least significant bits so that the completed product <SP>C</SP>/ A  (step e) is an error. The product <SP>C</SP>/ A  x A is then formed and the upper bits stored in register V and the lower bits stored in register D (steps f-h). Next, number D is entered into register M and shifted two bits right, the two least significant bits of C being included in the two most significant bits of D to form C new number D, (steps i, j) the differences between D<SP>1</SP> and the lower bits of <SP>C</SP>/ A  x A and C and the upper bits of <SP>C</SP>/ A  x A are then completed and stored in register M and V respectively (steps k-p) and the five least significant bits of the latter which constitute the error are used as the five most significant bits of D<SP>1</SP> - <SP>C</SP>/ A  x A to form a further lower number D<SP>11</SP> (steps q, v) <SP>D11</SP>/ A  and <SP>C</SP>/ A  are then completed (steps s-u) and <SP>C</SP>/ A  is again multiplied by <SP>1</SP>/ A  to derive <SP>C</SP>/ A <SP>2</SP>. The latter is multiplied by B and subtracted from <SP>D11</SP>/ A  (steps x-c<SP>1</SP>) so that registers W and D contain <SP>C</SP>/ A  and <SP>D</SP>/ A - (BC/A<SP>2</SP>) respectively. BINGO!

Title: Improvements in or relating to production of an adherent patina upon copper or its alloys
IPC: C25D11/34
Filed: 1934-08-17
Abstract: 426,115. Electrolytic surface treatment of metals. WITHERS, J. S., 51, Chancery Lane, London.-(Battelle Memorial Institute; 505, King Avenue, Columbus, Ohio, U.S.A.) Aug. 17, 1934, No. 23749. [Class 41] An artificial patina is produced on copper or its alloys by anodic treatment in a strongly basic solution of readily soluble carbonates. Carbonates or bicarbonates of alkali metals or ammonium are preferably employed. Sodium bicarbonate solution of strength 2-10 per cent, preferably 5-8 per cent, having a pH value above 8, are suitable. The initial current density may be 1-20 amps. per sq. dcm, preferably 1¢-4 amps. per sq. dem. With an 8 per cent sodium bicarbonate. solution and current density 18 amps. per sq. dcm., a sufficient coating is formed in 1 minute. The coating consists of a bluishgreen basic copper carbonate. On exposure to the atmosphere this becomes a true green by conversion to basic sulphate. Alloys which may be treated include brass containing up to 40 per cent zinc, aluminium, bronze, tin bronze, the alloy known by the Registered Trade Mark " Everdur," and an alloy containing 2-3 per cent nickel, ¢-1 per cent silicon and the balance copper. An alloy containing 20 per cent of nickel and 80 per cent copper does not produce a good coating but one containing 10 per cent of nickel may be treated. A roof may be treated by treatment with a wooden roller 1 having a copper cover 2 connected as cathode and an outer covering 3 of cloth impregnated with electrolyte. In the apparatus shown the electrolyte is delivered by a spray 7 from a tank 6. Slightly tarnished surfaces may be prepared by a light application of patina, after which any non-adherent parts of the coating are removed ; the coating produced by further treatment is then adherent. Very dirty copper should be first cleaned and pickled.

[Class 46] [See also Group XXXII] In filter-presses each filter tray or plate is suspended from a pair of rollers travelling along an overhead girder, rail, or runway, the rollers of each pair running on different tracks and being spaced one in front of the other so as to form a wheel base. The girder 11, Fig. 1, may be of inverted T. or I- section with the rollers 15 running on paths on its lower flange. Attached to each filter plate 10 are two oppositely inclined arms 16 each carrying a roller 15, the two rollers being on opposite sides of the central web of the girder. There may be a second roller path on each side of the web for alternate rollers to run upon, so that larger rollers may be used. Two girders 11 may be inclined towards one another as shown in Fig. 3 so that the tops of their inner flanges may be horizontal. The rollers 15 run on these inner flanges and the two arms 16 are carried by one attachment 17 on the filter plate. A carriage 19 travelling on the girders 11 supports a winding drum for lifting the roller units and filter plates when required. Fig. 5 shows an arrangement in which the attachment member 17 carries two vertical arms 16 having inclined bearings for flanged rollers 15, the two rollers being on opposite sides of the girder. Vertical rollers 20 prevent the rollers 15 from leaving the girder flange. These rollers 20 may be easily removable or fixed on axes adapted to swivel over to allow of removal of the attachment from the girder. The rollers 15 may be held in place by angle pieces fixed or hinged on the girder, or the edges of the flanges may be turned up. The roller paths on the girders may be sunk, raised, or flanged ; or they may be formed on bars, rails or angle pieces secured on the girders. The rollers may have two flanges, or their peripheries may be flat, grooved, rounded or V-shaped in cross section. The framing of the press may be constructed of steel joists. The plates may be raised above the side bars of the press and pressure applied to them at three points, the pressure at the upper point being applied by means of a pressure cylinder interposed between the end movable plate and an attachment to the girder.

Abstract: 1485879 Vehicle headlamps CHRYSLER UNITED KINGDOM Ltd 29 May 1975 [3 June 1974] 24556/74 Heading F4R [Also in Division H2] Lamps in a vehicle headlamp system have filaments to provide a main beam condition and two dipped beam conditions with different angles to suit the different attitudes of the vehicle for laden or unladen weights. As shown for a two headlamp system, the main beam is provided by filaments 12 and the more or less steeplyangled dipped beams by filaments 13, 14. The dipped beam filaments are switched automatically. When a load/height sensitive switch 30 closes, the coil 28 of a time delay bi-metallic switch 27 in a sidelight branch circuit 29 heats up to close the switch contacts. This operates a relay 21 to connect poles 20a 22a and illuminate steeply angled dip filaments 13 if a dip switch 16 has been closed previously. When the switch 30 is open, a spring holds contacts 20, 22 closed to illuminate the other, less steeply dipped, beam filaments 14. In a four-headlamp system, a further inner headlamp pair provide a main beam only (Fig. 2, not shown) or each pair of lamps contains a main beam filament and one of the two angled dipped beam filaments (Fig. 1, not shown). In an alternative switching arrangement, relay 21 is omitted and the dipped conditions are changed after a time delay by a bi-metallic switch (31) (Fig. 4, not shown) heated from a sidelight circuit when the load/ height switch 30 is closed.
