Title: Method of recovering waste gas from oxygen top blowing converter in unburnt state
Inventor: MAEHARA SHIGERU
IPC: C21C5/40
Filed: 1963-11-04
Abstract: A method of recovering CO-rich waste gas generated in the operation of an oxygen top blowing converter comprises cleaning the waste gas, detecting the CO content and the flow rate of the cleaned gas as it is passed to a gas holder for blast furnace gas via a gas mixer, delivering air or an inert gas, e.g. nitrogen, to the mixer in amounts regulated in accordance with the detected CO content and flow rate, to dilute the cleaned gas, and measuring the calorific value of the gas in the mixer and further controlling the delivery of air or inert gas to the mixer in accordance with the detected calorific value.  A valve in an outlet line from the converter directs CO-poor gas generated during the initial and final blowing periods of the converter to atmosphere.  The calorific value-detecting device actuates a valve in an inert gas delivery line to the mixer to maintain a predetermined calorific value of the gas mixture.

Abstract: 920,006. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. March 22, 1961 [Dec. 22, 1959], No. 43542/59. Class 40 (1]. [Also in Group XL (c)] A system for digitizing an unknown amplitude significant voltage of the type in which the unknown voltage is successively compared with a sequence of known voltages, each known voltage being so chosen in dependence upon the previous comparison that the sequence of known voltages converges towards the unknown voltage, this being the type described in Specification 694,907, which is referred to, is characterized in that the output of the comparator is applied to a gated amplifier which is only unblocked for a short period immediately after the known voltage has been changed. This reduces the risk of spurious amplifier outputs selecting the wrong known voltage. As described, Fig. 1, a sequence control device 12, successively turns on the stages of a register 7 which switches in successive binary weighted resistors of an analogue circuit 6. After each stage is turned on, the output voltage from the analogue circuit is compared with the unknown input voltage applied to terminals 1, 2, the comparison and the amplification of the difference signal being triggered by a control pulse on a lead 16 and as a result of the comparison the stage of the register just turned on is either left on (if the known voltage is less than the unknown voltage) or turned off (if the known voltage is larger than the unknown voltage). The sequence control circuit has twenty-two outputs, giving a twentytwo step cycle. The first three and the last two steps are used to check that the stages of the register will all turn on and off and that the final known voltage is within one unit of the unknown voltage. The gated amplifier is described in detail (Fig. 2, not shown) (see Group XL (c)), and includes transistors. Specification 920,007 which describes a modified switching circuit is referred to. Specification 789,541 also in referred to.

Title: Improvements in or relating to metal fibres
IPC: C23C10/60
Filed: 1964-10-26
Abstract: Chrome steel fibres are coated with alloying components containing Mo and/or Cu and/or V and/or Ta and/or Ti, homogenized by diffusion annealing and compacted to shape.  The chrome steel may contain Ni and/or Mn and by carrying out the annealing in a nitrogen containing atmosphere nitrogen can be introduced as an alloying constituent. The homogenized fibres may also be silicized.  In the Examples Cr-Ni steel fibres are chromized in H2 and HCl gas at 1200 DEG C., ferro-vanadium being added to the Cr or ferro chromium used. Alternatively chromium chloride containing 10% vanadium chloride is used. Annealing was carried out at 1300 DEG C. in H2 containing 10% NH3 and 1% HCl. Coating with Mo may be effected by deposition from molybdenum halides in H2 or electrolytic deposition from an aqueous solution of trivalent molybdenum compounds.

Abstract: 1,207,839. Protective arrangements. EX-CELL-O CORP. 25 Sept., 1967 [10 Oct., 1966], No. 43598/67. Heading H2K. A protective arrangement, e.g. for an electrochemical machining apparatus 12, comprises a filter circuit 28 for eliminating short transients from an input signal and supplying the longer signal variations to a first trigger channel 20, which provides an output signal only when the variation is an increase exceeding a predetermined value, and to a second trigger channel 22 which provides an output signal only when the variation is a decrease exceeding a predetermined value. The circuit 28 receives its input signal from a circuit 14 which may be similar to the differential amplifier and associated circuits used in the arrangement of Specification 1,204,191. The circuit 28 has two transistors to which the input signal is applied through separate resistor/capacitor delay circuits having different time constants which circuits together with a blocking diode remove the unwanted signal components. The trigger channels 20, 22 are transistorized and include adjusting units 36, 46 to adjust the sensitivity of the channels and to switch off the channels at the lower limit of sensitivity. The output signals from the channels 20, 22 are applied to an amplifier 48 which provides an output to turn off the apparatus 12 and to light a signal light, when permitted to do so by a gating control circuit 26. The circuit 26 is effective when the apparatus 12 is first switched on and blocks any output from the amplifier for a period sufficient to enable the apparatus to be started. Fig. 2 (not shown) illustrates the circuit elements of the complete protective arrangement.
Patent GB-436457-A (GB)
Abstract: 436,457. Colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. April 11, 1934, No. 10928. Convention date, April 11, 1933. [Class 98 (ii)] In making prints on a lenticular sensitive film, from colour - record images taken on a lenticular film, by employing the contact method with the embossed sides of the films facing each other, the convergence of the elementary rays which pass through the centres of the lenticles and the centres of the filter images behind them is preserved in the print by first making by contact an intermediate print, in which the convergence becomes divergence as shown in Fig. 2 for the principal rays DI, EK of two marginal lenticles, and from this print making, again by contact, a final print in which the convergence is restored. The Specification as open to inspection under Sect. 91 states also that the printing light must in each case be arranged so as to have approximately the same incidences on the films; this is achieved in printing the intermediate film by bending the two contiguous films to cylindrical form, and in printing the final film by exposing the contiguous unbent films to an extended source corresponding to the conditions when taking the original, as described in U.S.A. Specification 713,187. U.S.A. Specification 705,604 also is referred to. This subject-matter does not appear in the Specification as accepted.

Title: Devices for recording the distance travelled and speed of a vehicle
IPC: G01P1/12
Filed: 1968-09-13
Abstract: 1287734 Recording apparatus C L INSTRUMENTS Ltd 11 Sept 1969 [13 Sept 1968] 43709/68 Heading G1J Apparatus for recording the distance travelled and speed of a vehicle comprises means for driving a recording medium 11 at constant speed, means 20 for providing indicia upon the medium at intervals corresponding to equal distances travelled by the vehicle and a security device arranged to provide an indication on the medium 11 in the event of the apparatus being interfered with during a recording period. The recording medium 11 may be a tape or wire suitable to receive indicia in the form of visible or magnetic marks and as shown in Fig. 1 a paper tape is drawn from a supply spool 12 by a sprocket wheel 17, driven by clockwork or electric motor, through a punching mechanism 20 and over a take-up spool 13, whereby the spool 13 is driven. The punching mechanism 20 includes a gear wheel 21 driven at the rate of one revolution a mile and a punching wheel 22 linked by a spring 23 to the frame of the apparatus and by a shaft 29 to a cam 25 to operate a punch 26. As a flexible drive from the vehicle gear box rotates the wheel 21, pins 27, 28 engage to rotate the wheel 22, extending the spring 23. After turning through 180 degrees the punching action is completed under the influence of the spring 23. When the tape has been loaded in the apparatus, preferably by means of a cassette, the action of closing and locking its housing starts the tape drive and causes a hole to be punched in a second channel of the tape. The security device also provides indicia in this channel to indicate the end of a recording period, irregular opening and closing and removal of the flexible drive cable. When present the drive cable 38, Fig. 3 presses on a nylon shaft 39 and if it is removed a spring 36 frees a lever 35 from a wheel 33 which under the bias of a spring 34 stressed when the housing was locked, operates a punch. Parameters other than distance travelled may also be recorded in further channels e.g. fuel consumption, engine running time and vehicle load by arranging for the frequency of holes punched per mile in one channel to be proportional to the load.

Abstract: 1413064 Water quenching galvanized steel MANEELY-ILLINOIS 30 March 1973 [28 April 1972] 43741/74 Divided out of 1413061 Heading C7N A water quench apparatus for elongate material such as the galvanized steel tube formed according to the method of Specification 1413061 comprises a water trough 160 through which the elongate material is fed via apertures in inlet wall 161 and outlet wall of the trough and a water feed at the outlet which passes cooling water through the trough at a controlled rate countercurrent to the passage of the elongate material. A gasket in the outlet wall forms a seal with elongate material and a nipple 162 with a tapered front end 170 inserted into the inlet aperture 164 which is slightly larger than the diameter of the elongate material so that the water flows through clearance 166. The flow rate is such to maintain a temperature of 85-140F in the nipple. A temperature sensor in the nipple controls the amount of water supplied to the trough, the increased volume of water being held off at 168 by opening valve 169. This water and the water passing through the nipple into drain line 171 is recycled to the trough.

Filed: 1959-12-24
Abstract: 901,742. Truing lap &c. wheels. BOVENSIEPEN, H. F., [trading as WOLTERS, P., [Firm of]]. Dec. 24, 1959 [Dec. 24, 1958], No. 43847/59. Class 60. [Also in Group XXIX] A two-wheel lapping machine has a swivelling upper housing part with a drive to effect swivelling, the upper housing part and the fixed lower housing part being each provided with a seat for the reception of a truing tool. The lower lap wheel 4 is rotatably mounted in the fixed lower housing part 1 and the upper lap wheel 11 is rotatably mounted in an upper housing part 9 which can swivel on a vertical support 7 secured to the housing 1. The upper lap wheel 11 is vertically adjustable. The hub 14 of the upper lap wheel 11 has a seat 15, and the lower housing part 1 has a seat 18. The holder 16 of a truing tool 17, e.g. a diamond, can be received in either of the seats. With the holder 16 in the seat 15, swivelling of the housing part 9 effects truing of the lower lap wheel 4 and with the holder 16 in the seat 18, swivelling of the housing part 9 effects truing of the upper lap wheel 11. To effect the swivelling, the housing part 9 carries a spindle 26 on which is rotatable a pinion 28. Pinions 25, 27 are secured on the spindle 26. The spindle 26 is urged upwardly by a spring 24 but is moved downwardly, on starting a pump 47 to supply pressure medium to a cylinder 32, to bring pinions 28, 25 into mesh with a gear quadrant 23 fixed to the vertical support 7. Pinion 28 is always in mesh with a rack 30 having at its ends pistons 36, 37 and pinion 27 is always in mesh with a rack 29 having at its end pistons 34, 35. To swivel the housing part 9 in one direction, pressure medium from pump 47 is admitted, under control of distributing valve 46, to piston 36, thus moving rack 30 to rotate pinion 28 which rolls on gear 23 so that the part 9 swivels. Pressure medium displaced by piston 37 is admitted to the left of piston 34 and pressure medium displaced by piston 35 passes to exhaust through adjustable throttle valve 49. This prevents chatter and backlash in the gearing. The movement is reversed by actuating the valve 46.

Abstract: 1447332 Pipe couplings KANEGAFUCHI KAGAKU KOGYO KK 14 Oct 1974 [15 Oct 1973] 44474/74 Heading F2G A universal pipe-joint assembly suitable for use in underground conduits carrying electric cables comprises a first member 1 and a second member 4, the member 1 having an enlarged end portion 2, the latter having a part-spherical cavity 3 therein with an opening at its front edge, the member 4 having a hollow part-sphere 6 at one end 5, the outer surface of the partsphere 6 having a diameter greater than the width of the opening, the part-sphere 6 being held with a snug fit within the cavity 3, both members 1 and 4 being made of a plasticized PVC resin. The mechanical strength of the joint may be increased by embedding a metal O-ring 7 in the front edge of the end portion 2 or by compressing the end portion 2 with a wrapping or strap. Members 1 and 4 may be moulded from a PVC paste composition, the former being allowed to set but the hollow part-sphere 6 of the latter being inserted, whilst still sufficiently plastic, into the cavity 3. The part-sphere 6 is then allowed to set. The member 4 is conveniently made by rotation moulding, but a conventional moulding technique can be used when the PVC paste composition contains only non-reactive plasticizer. In this instance the desired plasticity of the part-sphere 6 is obtained by applying heat. A typical paste composition includes non-reactive plasticizer and stabilizer as well as, preferably, reactive plasticizer and catalyst. Appropriate chemicals and examples are given.

Heading D1T [Also in Division H2] Two conductors C, C<SP>1</SP>, Figs. 1 and 2, are secured together by a number of similar elongated elements 22, Fig. 3, each having two helically formed end portions, which are of sufficient internal helical diameter and pitch length and knurled 24 along longitudinally spaced inwardly facing surfaces so as to grip the conductors, and an intermediate portion adapted to flex and having a smooth surface uninterrupted by knurling. Knurling includes notches, lines, grooves and serrations extending transversely of the helical axis. The intermediate portions of the elements 22 are not knurled so that they retain their maximum strength, since if any stress is applied to the system they solely bear the stress in the region 26 between the conductors C and C<SP>1</SP>. Fig. 4 shows a conducting cable centre splice 40 employing fewer elements 22 so that end portions 42 and 44 form a partial lay, the intermediate portions being tightly twisted. Fig. 6 shows a splice shunt in which the intermediate portions of the elements 22 are subdivided into tightly twisted groups 52 which are disposed around a conductive splice 51. In a further embodiment (Figs. 7 and 8 not shown) elements 22 form a cable spacer for two parallel lines, the intermediate portions being tightly twisted and connecting or holding the two lines in spaced relationship. In a further embodiment (Figs. 9 and 10 not shown) elements 22 are wrapped around a conductor, the intermediate portions forming a tightly twisted loop which is used to attach the conductor to a support. In a further embodiment (Figs. 11 and 12 not shown) elements 22 form a dead end for a guy wire, the intermediate portions of the elements being tightly twisted and forming a closed loop with the end portions intertwisted around the end of the guy wire.
