Abstract: 1,172,214. Indicating position of oxygen lances. ALLEGHENY LUDLUM STEEL CORP. 5 March, 1968, No. 10728/68. Heading F4B. [Also in Division C7] The position of an oxygen lance 20 relative to the slag-metal line in a basic oxygen converter 10 is determined by probes 22, 24 releasably clamped to the lance and extending below the lance, one at least by a specified distance x and the other by at least that distance. The probes form part of an electric circuit including an indicator 30, the circuit being completed as the probes become immersed in the slag layer 18 and the conductivity increasing to a maximum (shown on the indicator) when the probes touch the molten metal 16. When this reference position has been determined, the lance is raised a desired distance above the level of the metal to begin the blow. Preferably, and as shown, the probe 24 extends an arbitrary distance below the probe 22, the reference position being indicated when the probe 22 contacts the molten metal.

Abstract: 1444672 Vehicle wind deflectors W BAIER W BAIER L SCHOBER and E SCHLUMPRECHT 11 March 1974 [19 May 1973] 10732/74 Heading B7B A wind deflector 1 includes a resilient portion 9 so that when a sliding roof panel 11 is opened, the deflector moves automatically to its open position. As the panel 11 is closed, the deflector is depressed by the action of panel projections 12 on levers 4 which connect the deflector to the sides of the roof opening. The deflector is mounted by the insertion of a tongue 7 in a slot formed by a clip 8. As illustrated, the clip 8 is on a lower horizontal part of the roof opening frame so that the resilient portion of the deflector is pressed against a frame part 10 to guard against inadvertent withdrawal. In an alternative arrangement, Fig. 4 (not shown), the clip is on the frame part 10 and engagement of the torque may be secured by a snap action component. In addition to the opening bias provided by the construction of the deflector itself, springs may bias the levers 4 towards the open position.

Abstract: 964,546. Laminates. FMC. CORPORATION. March 22, 1962 [April 27, 1961], No. 10961/62. Heading B5N. Decorative laminates comprising a sheet of resin-impregnated decorative paper bonded to a rigid core, for example of plywood, hardboard, particle board, cement-asbestos board or gypsum board, are made by densifying the paper by supercalendering, impregnating it with a solution in a volatile solvent of diallyl or dimethallyl orthophthalate or isophthalate containing 90-98% of a thermoplastic polymer of the above materials (m.w. 2500-25,000), 2-10% of the monomer, and a catalytic amount (not less than 1%, preferably 2-5%) of an organic peroxide, drying the paper to 53-67 % of its weight of resin, and laminating it to the core material with heating and pressure sufficient to cure the resin to the thermoset stage. An unpigmented overlay paper may be similarly treated and applied over the decorative paper before the laminating step. To avoid distortion of some cores, a phenolic resinimpregnated kraft paper layer may be applied to the underside of the core with an intermediate separator layer of glassine paper. Pressing is preferably effected with highly polished plates and produces laminates with a high and uniform surface gloss. The impregnated and dried papers are storable before use. U.S.A. Specifications 2,370,578 and 2,377,095 are referred to.

Title: Improvements relating to the manufacture of meal for fertilizing and other purposes and for recovery of oil from fish or vegetable refuse and the like
IPC: C05F1/02
Filed: 1924-05-07
Abstract: 215,765. Hiller, S. May 7, 1924. Fats and fatty oils, extracting by pressure.-In apparatus for expressing oil from fish, fish waste, garbage, vegetables, grains, or seeds, and for making meal for feeding and fertilizing purposes from the resultant cake, the operations of cutting, cooking, pressing, drying, grinding, and cooling are continuous and automatic, and air is practically excluded until after drying. The fish &c. is fed into a hopper 3, where it is pressed against revolving cutters by wheels 5. The pieces fall to a chamber 26, are raised by a conveyer 21 to a chamber 27, taken by a screw conveyer 28 to a hopper 30, and fed by a revolving star-wheel 31 to a cooker 33. The partly cooked material falls down a passage 34 to a second cooker 36, from which it is discharged by a star-wheel into an extrusion press 58. The expressed liquid passes through the perforated casing into a pan 60. The " cake " is discharged into a hopper 65, falls down a chute 66 to a revolving and slightly inclined dryer 71, from the right-hand end of which it falls to a similar dryer 74 inclined downwards to the left. The discharged dried material is lifted by a conveyer 100 to the hopper 104 of a grinder 105, from which the meal falls through a chute 106 to an inclined revolving cooler 110 discharging into a bin 116. The chute 66 is heated by gases from the oil or other furnace 69, the gases then passing to a stack 73 via the dryers 71, 74. A ledge 72 is provided in the chamber 67 of the furnace to shield the " cake " from direct contact with the gases until sufficient steam has been generated to cool the gases and protect the material. Ribs 87, 88, 115, preferably helical, are also arranged in the dryers 71, 74 and the cooler 110 to agitate and govern the rate of feed of the material. The pitch of the ribs 87 near the chamber 67 may be shorter than of the more distant, and the ribs 87, 88 may be so arranged as to give different rates of feeds at other parts of the dryers. The steam for the cookers 33, 36 may be generated at the furnace 69 or independently, and is used in the cookers at different pressures and temperatures according to the material treated. Steam escaping through the feed-wheel 31 enters the casing 24 of the conveyer 21 and preheats the material. The passage 34 is extended beyond the lower cooker 36 and fitted with a removable cap 35, so that tools or other foreign objects drop into the sump and may be removed periodically. The screw 59 of the press 58 may be removed by rotation of a handwheel 60. The apparatus is preferably driven from one source-a pulley 117-and the shafting and gearing is so arranged as to drive the various parts at such relative speeds as to ensure continuous operation, whatever the speed of the pulley.

Abstract: 857,067. Radio navigation; automatic phase control systems. STANDARD TELEPHONES & CABLES Ltd. April 3, 1959 [April 4, 1958], No. 11419/59. Classes 40(5) and 40(7). Relates to a mobile receiver of the type disclosed in Specification 851,466, for indicating the bearing of the receiver from a TACAN radio beacon transmitting a rotating multilobe pattern, Fig. 2 (not shown), together with coded groups of main and auxiliary reference pulses from which are derived at the receiver 15 c/s. and 135 c/s. coarse and fine bearing dependent sinusoidal signals, 15 c/s. and 135 c/s. main and auxiliary sinusoidal reference signals and a 15 c/s. main reference pulse 78 derived from a blocking oscillator 36. The 15 c/s. bearing- dependent signal from a filter 25 is applied through a coarse phase shifter 42 controlled directly by a two phase motor 50 to a coarse phase comparator 41 together with the 15 c/s. reference signal from the filter 40 to give a D.C. error voltage which is converted into a corresponding A.C. signal in a modulator 52 and applied to the control winding of the motor 50. A further output from the coarse phase shifter 42 is applied to a gate pulse generator 57 whose output is applied together with the reference pulse 78 to a coincidence detector 59 such that when the phase difference between the inputs to the coarse phase comparator has been reduced to Œ20 degrees the output from the coincidence detector 59 operates a relay 56 to disconnect the coarse phase comparator 41 from the motor control circuit 52 and connect in its place the output from a fine phase comparator 47 to which is applied the 135 c/s. bearing-dependent and reference signals from filters 26 and 45, the latter signal being applied through a fine phase shifter 46 driven by the motor 50 through a 1 : 9 gearing 49; the required bearing is given by an indicator 51 coupled to the motor 50. According to the present invention an A.C. generator 38 is driven by the motor 50 and the output from the generator 38 is applied to a centre tap on the primary winding of a transformer 34 whose secondary is coupled to the grids of the valves 69, 70, in the motor control circuit 52, the outer ends of the primary of the transformer 34 being selectively earthed through an additional armature on the relay 56 such that when the motor 50 is being controlled by the coarse phase comparator 41, the generator 38 provides positive feedback thereby speeding up the motor and preventing it from coming to rest in a position corresponding to the unstable null output from the phase comparator 41 but when the motor 50 is being controlled by the fine phase comparator 47 the generator 38 provides negative feedback thereby preventing hunting.
