Title: Improvements in or relating to process of producing aluminous metal extrusions
IPC: C22C21/00
Filed: 1951-07-03
Abstract: In order to produce extruded forms having low temperature annealing characteristics, a billet of aluminium alloy containing 0.01-0.5 per cent iron and silica, the ratio of iron to silica not exceeding 4/3 and an element such as nickel or beryllium to reduce the temperature of recrystallisation after cold-working, is heated to between 850 DEG and 950 DEG F. for 1-12 hours, cooled at a rate not exceeding 50 DEG F. per hour to between 500 DEG  and 650 DEG F., held at this temperature for 1-12 hours and then extruded at between 400 DEG  and 550 DEG F.  The amounts of nickel or beryllium would be 0.04 per cent.-1 per cent. and 0.005 per cent.-0.25 per cent. respectively. After the extrusion of the billet, the extruded form is cold-worked to give a reduction of at least 40 per cent and preferably more than 90 per cent, either in a single operation or with an intermediate annealing.  It was found that the recrystallization temperature of the work was below 600 DEG F. or even below 450 DEG F. in some cases. The invention is useful in the production of aluminium sheathed cables where, after the sheathing has been drawn down on to the cable, it is desired to anneal it at a temperature that will not harm the insulation.  Specification 711,860 is referred to.

Title: Closed-loop mixture control system for an internal combustion engine with means for transitional response
IPC: F02D41/14
Filed: 1976-04-21
Abstract: 1502726 Automatic control of engine exhaust NISSAN MOTOR CO Ltd 21 April 1976 [23 April 1975] 16080/76 Heading G3R A system for controlling the air/fuel ratio supplied to an I.C. engine in reponse to an exhaust gas sensor has means responsive to an abrupt change in operating conditions for applying an additional control signal to compensate for the error which would occur due to the response time of the system. In the embodiment, throttle position is sensed to produce a voltage (a) proportional thereto; this is differentiated to produce signal (b) which charges a capacitor via a diode in one of a pair of oppositely poled RC circuits to provide the compensating voltage (c), decaying over a time sufficient for the normal system to become stabilized at the new throttle setting. The normal system has a zirconium dioxide sensor of oxygen whose output has a steep transition at stoichiometric mixture and the difference between this and a reference is applied to a PI amplifier whose output is converted to constant frequency width modulated pulses for control of an unspecified fuel metering device. A detailed circuit is described. A "three-way" ' catalytic converter is fitted downstream of the exhaust sensor.

Title: A clamping device, for use particularly in clamping together two parts of a mould
IPC: B29C33/20
Filed: 1941-12-17
Abstract: 553,079. Clamps. LEADER, S. A. Dec. 17, 1941, No. 16306. [Class 44] [Also in Groups V, XIII and XVIII] A device for clamping together two parts of a mould, e.g. of a dental flask, comprises a bimetallic member composed of two metals having different coefficients of expansion rigidly joined together, the device being so arranged that as the temperature increases the member becomes distorted and exerts, directly or indirectly, an increasing pressure, tending to force together the two parts of the mould. The parts of the mould itself may serve as parts of the clamping device. In Figs. 1 and 2 the clamping device comprises two horizontal members 1, 2 joined by two bimetallic members 3, 4 each comprising two strips riveted together. A thumb screw 5 (or a vertically movable platform) holds together the two parts of a dental flask 6. The strip having the higher coefficient of expansion is on the outside, so that when the dental flask is heated the members 3, 4 bend as in Fig. 2. The pressure may be exerted on the flask indirectly through a rod &c. disposed between the flask and one of the members 1, 2. In modifications :- (a) one or more bimetallic wedges or pins are driven between the top of a flask and a wall of a rectangular frame in which the flask stands. The wedges &c. may be fixed to the frame. The two parts of the wedge or pin may be joined together at one or more places or over the whole of the contacting parts. (b) In a frame somewhat similar to that shown, the part 2 is the bimetallic member. (c) The bimetallic member is carried on the lower end of the screw 5. (d) Figs. 9 and 10. Two bimetallic pins 15 are inserted in the holes 18, provided for the reception of ordinary pins, in a standard dental flask.

[Class 97 (ii)] An indicating and recording device for the direction of the air stream adjacent to an aircraft comprises a vane pivoted about two axes normal to one another. A hollow shaft 12 projecting from the fuselage 14 has secured to it a vane 11 the movements of which about the axis of the shaft 12 are indicated by a pointer 20 and scale 21 and recorded by a pen 24 on a travelling band 25 the pen being operated by a rack 23 and a pinion 22 on the shaft 12. The vane 11 is also connected to a rod 30 slidable in the hollow shaft by a link 31, lever 32 pivoted to cheeks 29 carried by the shaft 12, one end of which lever 32 is linked by link 34 to a lug 35 on the vane so that movements about an axis normal to that of the shaft 12 produce an endwise movement of the rod 30. This endwise movement is converted into a rotary movement by helix and nut to rotate a pointer 38 against the scale 21 and also by rack 39 and pinion 40, shaft 41, pinion 43 and rack 44 operates a pen 45 to record the movement of the travelling band 25.

Band; blocks and shoes acting on drum ; compensating for wear. -Internal expanding brakes as described in the parent Specification are provided with means for giving support to the flexible band in a radial direction while permitting peripheral movement thereof. Means may also be provided for adjusting the clearance of the band or shoes from the drum. The brake shown comprises a pair of rigid shoes 2, 3 connected by a flexible band 1 as described in the parent Specification, the ends of the shoes being respectively connected to a fixed pivot and engaged by an operating cam. The flexible band may, the shoes, be provided with friction lining material. The support for the band 1, according to one construction, may comprise a bracket projecting from the fixed carrier plate, and upon which the band rests, or in a slot in which it engages. The bracket may be adjustable to vary the clearance between the band and the drum. In another construction, the band has a small depending tongue 12, Figs. 6 and 7, carrying a pin 14 projecting into a slot 13 in the carrier plate. To enable adjustment of the clearance of the band from the drum to be effected a collar of say, hexagonal form, may be mounted eccentrically on the pin 14. This collar may be turned on the pin so as to enable. one or other of its pairs of faces to engage the upper and lower surfaces of the slot 13. To adjustably limit the peripheral movement of the band in one or both directions, a screw 19 or a pair of screws may be provided for engagement with the pin 14, or as shown, an adjustable pulloff spring 18 may be provided on one side of the pin 14. The slot may be formed in the tongue 12 and the pin be carried by the carrier plate. The support for the band 1 may instead comprise an eccentric bolt mounted on the carrier plate. Similar bolts may also be arranged to engage the shoes 2, 3.
