Abstract: 1438208 Molten electrolyte anode SWISS ALUMINIUM Ltd 15 Oct 1974 [16 Oct 1973] 44730/74 Heading C7B A molten electrolyte 3 is electrolyzed e.g. to produce Al, Mg or Be in a cell fitted with at least one anode having a working surface 2 of ceramic oxide and a system of pores 7 and/or passages 8 which permit a stream of oxidizing gas to at least those parts of the working surface not protected against corrosion by a sufficient current density. The oxidizing gas, e.g. oxygen, air, chlorine, fluorine, carbon dioxide and/or any oxide of nitrogen, may be led from an external source via the anode interior to those parts of the surface Fig. 1, and/or gas produced at the anode by electrolysis may be led from areas on the surface where there is sufficient current density to areas with insufficient current density Fig. 2. The flow of the gas is preferably at least 0À01 m. mol/hr. For Al production the electrolyte may be cryolite or alumina. As shown Fig. 1 the anode includes a metal, carbide, nitride or boride conductor 1 with gas passage 4, and a current distributor 5 consisting of a hollow body or wire network in the anode centre which can at least in part be penetrated by a gas and at 1000C does not react with the gas or ceramic oxide. The distributor is preferably made of Ni, Cu, Co, Mo, or alloy based thereon, or carbide, nitride and/or boride. The ceramic oxide part 2 may be based on an oxide of Sn, Fe, Cr, Co, Ni or Zn; e.g. SnO 2  with 0À01-20% of additive oxide of Mn, Fe, Sb, Cu, Nb, Zn, Cr, Co, W, Cd, Zr, Ta, In, Ni, Ca, Ba or Bi. For a completely immerses anode Fig. 2, the conductor 1 is covered with a protective layer 6 of BN, electromelted Al 2 O 3  or MgO.

Title: Non-linear correction of waveforms
IPC: H04B15/00
Filed: 1973-09-25
Abstract: 1448697 Pulse shaping; television POST OFFICE 6 Sept 1974 [25 Sept 1973] 44888/73 Headings H3P and H4F In a waveform correction circuit, the input signal is differentiated at 3, fed through a circuit 6 having a non-linear skew-symmetrical input-output characteristic, differentiated again at 7 and combined with the input signal delayed at 4. Circuit 6 is preferably a sign preserving square law circuit and a sign preserving squareroot circuit may be provided additionally between amplifier 8 and the combining circuit 9. If the combining circuit adds the signals, the effect is to shorten signal rise time thereby crispening input video signals. If the combining circuit substracts, ringing is reduced at the expense of a longer rise time, and this mode of operation may be used to reduce the slope of waveforms emanating from wide-band sources such as television cameras for limited band processing such as digital encoding or recording. A plurality of circuits shown in Fig. 1 may be connectecd in cascade.

[Also in Division F2] A washing machine control system includes a vacuum source 46 actuated by a programme unit 28, and controlling an actuator 52 which mechanically modifies the action of a component. The tube 12 and agitator 14 are driven by motor 20 via a variable pulley 22, belt drive 25, and transmission 15. The programme unit sequentially controls electrically operated components including the motor. Pulley 22 manually drives the transmission at a minimum speed but can be adjusted by a pivoted lever 35. The lever is raised by the diaphragm 54 of actuator 52 when the vacuum pump 43 is actuated by the unit 28 via cam operated switch 57. The speed of the tub or actuator can therefor be increased during part of the operating cycle. As shown the lever is moved between adjustable stops 39, 40 so that the speed has discreet maximum and minimum values. Alternatively the position of the lever, and thus the speed can be set manually. In modifications the vacuum source may be driven by the motor, or only actuated when the motor is energised.

Title: Process for treating glass surfaces
Inventor: POOLE JAMES PRUVIS
IPC: C03C21/00
Filed: 1965-10-26
Abstract: Soda-lime glass durability is increased by treating with fluorine sufficient to cause ion exchange with oxygen or hydroxyl ions but insufficient to produce discernable etching of the surface.  The treatment may be carried out at ambient temperature or at the temperature normally used in glass treating or forming operations. Thus the glass may be treated with a solution of hydrofluoric acid (0.05 to 5% available fluorine) or by injecting a fluorine-containing compound into the atmosphere of a glass blowing or glass-forming machine (14 parts per million available fluorine) for blowing, 2.5% available fluorine for glass-forming.

On pulling the flat plate trigger 17, which is held in the ready position by the compression spring 30, the downwardly and inwardly facing lugs 24, 25 on the cranked trigger rods 18, 19 engaged by the trigger move rearward until the fixed rod 29 trips the sear engaging the bolt, thus causing the gun to fire. The recoil of the breach mechanism is damped by the lower edge 56 of the forward traverse wall 13 engaging the plunger 55 in the sliding member 51 which forces the buffer member 48 rearwards against a system of compression springs 42, 43, 44 and 46 preferably in combination with brake rings 47. The compression spring 15 returns the breech mechanism. The breech member 2 may be removed from the barrel 12 attached to the grip member 1 by lowering the plunger 55 and sliding member 51 into the recess 59 by means of a hammer shaped fitment (54) attached to the lower edge of the sliding member 51 which is normally flush with the trigger aperture 53 and then sliding the breech member rearwards against the spring 15 so that the edge 56 passes over the plunger 55 with the recesses 60 in the guide grooves 11 are immediately beneath the guide projections 9, when the breech member 2 can be lifted upwards and removed forwardly from the firearm. In order that the firearm cannot be fired without the sliding member 51 and plunger 55 being returned to their operative position the sliding member 51 is provided with projections 63 in recesses 61 into'which projects the forward end 62 of the trigger 17 when the sliding member is in the depressed position thus preventing pulling of the trigger.

A metal flexure 10 is die-formed as a single piece with a necked down portion, which comprises a central die replication area flanked on each side by a metal flow generated curve area and has surface quality, cold working and grain continuity the same as in the original piece, the flexure resulting from die forming action on the piece whilst constraining the edges of the piece. The strip to be formed is placed in a flexure carriage 23 and lies at an angle other than 90 degrees with respect to a fixed die 22. The carriage is pressed by springs 29 against fingers 30. As the top die structure 31 is moved down it moves the carriage 23 down with it, by means of pins 38 attached to levers 35. The carriage is connected to the levers by pins 37 which engage in holes 36 so that it moves at half the speed of the structure 31. Lateral constraint of the flexure 10 is provided by shoes 39, which are engaged by buttresses 27, 28 and the edges of the flexure. The outer ends of the shoes are locked by friction to the buttresses and with a small pivot action, the inner ends move downwards with the flexure, Fig. 14 (not shown).
