Patent GB-680513-A (GB)
Title: Glass feeder
IPC: C03B7/10
Filed: 1951-01-03
Abstract: 680,513. Glass. CORNING GLASS WORKS. Jan. 3, 1951 [May 18, 1950], No. 268/51. Addition to 668,904. Class 56. In apparatus for feeding mould charges from a body of molten glass at widely spaced intervals, the flow, instead of being continuous as in the parent case, is interrupted between mouldcharging operations, and is restarted, by a small upward movement of the needle-valve, at a predetermined time before the mould charge is formed by a complete upward and downward movement of the valve. The gob is severed, as before, by two operations of the shears, a shoot being temporarily positioned to receive the severed cullet. The needle valve is operated by a cam 20 and the glass stream is severed by shears 23, 23' operated by a cam 25 and linkage, as described in Specification 227,078, [Class 56]. The cams are mounted on a shaft 26 which is driven through reduction gear by a chain from a shaft 30 which is driven by a motor through a single-revolution clutch whenever the clutch control cam 32 is freed for rotation. When a mould is to be charged, the contacts 40 of a timing-device T, which determines the periodicity of charging, close and energize a solenoid 37 which moves the bell crank 34 against the action of the spring 36 and releases it from the cam 32. The bell crank is held away from the cam 32 by a spring-urged lever 41. The shaft 30 thus starts to rotate and the needle valve starts to rise, but whilst the valve is still in an intermediate position, contacts 46 are momentarily closed by an arm 49 on the cam shaft 26, the consequent excitation of the solenoid 45 withdrawing the lever 41 from the bell crank which swings into position to lock the disc 32. The duration of glass flow through the partially opened outlet is sufficient to flush away any chilled glass, the flushing period being ended by a timing-device T<SP>1</SP> which excites solenoid 37 by closing contacts 50, the bell crank 34 being again disengaged from the disc 32 and locked by the lever 41 to permit the completion of the upward needle-movement. This movement causes necking of the glass stream and is immediately followed by the actuation of the shears by the cam 25, the cullet shoot 56 then being withdrawn, against the spring 65, by a pneumatic unit 55 controlled by a valve 53 actuated by the cam 52. At about the same time, contacts 57 in the operating circuit of the timing-device T<SP>1</SP> are opened by cam 52, enabling it to re-open its contacts 50. The needle completes its upward movement and then descends to extrude a mould charge. Just before the needle reaches its closed position, the cam 25 again operates the shears to separate a mould charge, the arm 48 at that time again closing contacts 46 momentarily to release the bell crank which then locks the disc 32. The shoot 56 then returns to beneath the outlet in readiness for the next operation, the timing- device T<SP>1</SP> being re-set by a closing of the contacts 57.

Title: Improvements in or connected with the starting of internal combustion engines
IPC: F01L13/00
Filed: 1931-01-06
Abstract: 370,488. Starting. HEYWOOD, C. F., 4, Rue Eglise Catholique, Montreux, Switzerland, Jan. 6, 1931, No: 492. [Class 7 (v).] Starting is effected by supplying compressed air to the working cylinders in turn during the power stroke, supplying a mixture of compressed air and fuel during the compression or suction stroke, and delaying the commencement of each opening movement of the exhaust valve during starting. The commencement of each closing movement of the inlet valve may also be delayed during starting or, in compression-ignition engines, the inlet valve may be caused to close earlier than in normal running in order to facilitate ignition by increasing the compression temperature and pressure. In an engine in which the exhaust valve normally opens 50‹ of crank angle before the lower dead centre and the inlet valve normally closes 40‹ past the lower dead centre, the exhaust valve during starting is opened at the lower dead centre and the inlet valve may be closed at 90‹ past the lower dead centre, so that exhaust takes place during the whole of the exhaust stroke, while the effective compression stroke is reduced to 90‹ of crank angle. Figs. 4 and 5 show a suitable inlet-valve cam b, mounted on an axially movable cam shaft a and provided with a starting inlet cam b<1> of the required extent, the extension b<2> being bevelled on the side b<3>. The exhaust cam may be similarly provided with a normal-running cam and a shorter starting cam, and the cam shaft may be moved axially by a piston actuated by the pressure of the starting fluid. In a modification, Figs. 8 and 9, in which the cam shaft is not moved. axially,' inlet and exhaust valve levers r are provided with stepped lateral extensions t, u which can be brought over the valve stems e and push-rods q by axial movement of the valve levers on the spindle s. This is effected by turning a collar w having inclined faces w<1> engaging corresponding faces on the bosses r<1> on the levers,'which are held in engagement by springs y. In a further form, the valve levers.are mounted on adjustable eccentrics, the eccentrics of the inlet and exhaust valve levers being oppositely disposed, and the eccentrics being adjusted by. interengaging pinion's on the shaft. carrying the eccentrics and a shaft parallel thereto.' Specification 168,614, [Class 7 (v), Internal-combustion engines, Starting &c.], is referred to.

Title: Improvements in or relating to sodium-lead alloys for the production of tetraalkyllead compounds
IPC: C07F7/24
Filed: 1952-01-08
Abstract: A process for making a tetra-alkyl-lead compound comprises alkylating (e.g. ethylating) a non-porous alloy of sodium and lead which has been solidified in a period of not more than 2 1/2 minutes, preferably not more than 30 seconds.  The alloy proportions are preferably 10 per cent Na and 90 per cent Pb and when comminuted the alloy should have more than 90 per cent of its particles larger than 100 mesh and preferably more than 50 per cent over 50 mesh.  One example is given describing the preparation of tetra-ethyl-lead.  The process may be carried out using intermetallic compounds of sodium and lead, e.g. NaPb, Na2Pb4, Na4Pb, and also with mixtures of these elements not corresponding to intermetallic compounds, e.g. Na2Pb.ALSO:A sodium-lead alloy, for use in the alkylating process of making tetraalkyllead (see Group IV (b)), is produced by solidifying a molten mixture of sodium and lead in a time interval of not more than 2 1/2 minutes, preferably not more than 30 seconds.  The alloy should preferably be kept quiescent in an inert atmosphere during the cooling period and when comminuted should have more than 90 per cent. of its particles larger than 100 mesh and preferably more than 50 per cent. over 50 mesh.  The alloy proportions may be 10 per cent. Na and 90 per cent. Pb and the accelerated cooling of the alloy may be achieved by dropping into cold liquid baths, passing droplets through cold inert gas, depositing a thin film on to a rapidly moving cold surface or extruding through a small diameter cold die.

Title: Improvements in or relating to hydraulic anti-skid systems
IPC: B60T8/32
Filed: 1970-01-07
Abstract: 1,271,761. Antiskid braking systems; valves. TRW Inc. 7 Jan., 1970 [2 June, 1969], No. 844/70. Headings F2F and F2V. In an antiskid system for vehicle brakes the rotor 26 of a pump is driven from the vehicle transmission at a velocity proportional to the angular velocity of a wheel to generate an hydraulic pressure which is fed to a pressurecompensating valve 60, comprising a bore 61 in which moves a spool 62 having axially spaced lands 63, 64 for regulating flow through axially spaced orifices 66, 67, 68, the spool being preloaded by a coil spring 69, to a throttle valve 80 and the brake motors, valve 80 being operated by a master cylinder 94, and the pump housing contains a spool valve 39 which normally bypasses pump generated pressure from outlet 34 to inlet 33. Application of pressure to the brake pedal causes pressure from the master cylinder to start to close the throttle valve 80 so that a surge through line 100 from pump to valve 60 causes the latter to increase system pressure and the increased pressure acts on the brake motors. Decreasing wheel speed results in reduced speed of operation of the pump and lessening flow causes a pressure drop through the valve 60, releasing brake pressure allowing speed-up of the wheels and the pump. The cycle is repeated until the vehicle is stopped.
