Title: Improvements in methods and apparatus for electrochemical machining
Inventor: DICKSON ERIC WINSTON
IPC: B23H3/04
Filed: 1964-01-30
Abstract: In electro-chemically machining a metal or a metallic workpiece using unidirectional current and a tool having an electrolyte feed passage therethrough, the current is derived from a constant source which delivers a constant current (within limits) with variations in the load impedance (within limits) and the advance rate of the tool into the workpiece is kept constant independently of other conditions of the machining operation.  By this means the working gap and side clearance between the tool and workpiece are kept constant. The constant current source may be electronically controlled.  A hole 0.044 inch in diameter may be drilled in a Ni alloy using a tubular metal tool having an insulating outer sheath, electrolyte being supplied through the tool bore, the tool advance rate being 0.030 inch/min. and the current being 0.386 amp.

Title: Improvements in means of and apparatus for conducting telephony through cables over long distances
IPC: H04B3/00
Filed: 1934-02-07
Abstract: 432,967. Telephone transmission systems. ESTAUGH, W., 32, Draycot Road, Wanstead, Essex. Feb. 7, 1934, No. 4013. [Class 40 (iv)] For transmission over a cable comprising a signalling conductor a separated from a concentric return conductor e by a shielding conductor b, the receiver o is connected through a transformer h across the conductors a, b, both of which are connected to the positive pole of a charging battery f, the negative pole being connected through a resistance g to the return conductor e, while at the other end the conductor a is connected to the transmitter n through a transformer m and to the positive pole of a battery i of lower voltage than f, the negative pole being connected through resistances k, j to the conductors b, e and in some cases through a resistance l to the conductor a. Signals from the transmitter n increase or reduce the effect of the battery i which opposes the potential of the conductor a due to the battery f. By varying the resistances g, j the potential of the return conductor e is adjusted so that it induces in the shielding conductor b a charge equal and opposite to that induced by the signalling conductor a, and thus ensures transmission without retardation or distortion due to capacity effects.

Title: Improvements in or relating to postal sorting apparatus
Inventor: PIGGOTT JOHN
IPC: B07C3/08
Filed: 1950-02-16
Abstract: 716,231. Letter sorting. POSTMASTERGENERAL. July 26, 1951 [Feb. 16, 1950] No. 4037/50. Class 78 (1) A letter (Fig. 1) is fed to presentation unit P where it is viewed by operator O who operates keyboard K in accordance with its destination so that the letter is fed by rollers 57, 58 between endless bands 64, 65 which lead it upwards and then downwards, at which latter position diverter fingers 74, 75 deflect the letter so that it falls on the appropriate conveyer of the series B1-6. As shown, the letters are fed to said unit P by a separator and are fed from said unit P to destination boxes. In unit P the letter (Fig. 5) comes from the side into trap 14 and is held therein by floor 17 secured to shaft 19 operated by solenoid 23 against spring 20 to release the letter which then falls into trap 15 where it is retained by similar floor 24 cooperating with wire fingers 26 which press the letter against transparent viewing panel 12. Both sets of fingers rotate to release the letter which falls into trap 16 whence it falls upon withdrawal of similar floor 39. Trap floor 24 (Fig. 1) is secured to shaft 25 and fingers 26 are rotated by solenoid 32. Thus, arm 29 loose on shaft 27 rotates to drive arm 37a secured to said shaft 27 by engagement with pin 36A thereon, and said arm 29 is connected by link 34 with arm 28 loose on shaft 25; pin 38 co-operating with pin 36 on arm 37 to drive shaft 25 rigid with said arm 37, and member 35 carrying catch 36 to hold pin 36. Thus a heavy letter cannot displace the floor 24 and so cannot release itself. In an alternative form of trap floor (Fig. 14) flaps 44 are closed by spring 48 and are opened by vertical movement of plate 52, extensions 49 of the flaps engaging in slot 53 of the plate, and the letter being actuated by solenoid 50. Letters (Fig. 12) descending with the conveyer 64 (which is formed of endless tapes) are diverted therefrom into shoot 81 and thence on to one of the discharge conveyers B1-6, the diversion being effected by a set of fingers 74, 75 pivoted at 76, 77 respectively. These fingers are operated by a solenoid (not shown) so that finger 75 moves to the right to discharge the letter and finger 74 moves to guide the discharge letter into the shoot. Cancelled letters fall into collecting box 70. Specifications 632,403, 712,031, [Group XVI], and 722,792, are referred to.

Filed: 1929-02-09
Abstract: 330,509. Andrews, C. W., and Chapman, W. B. Feb. 9, 1929. Producers.-In a gas producer in which either water gas or producer gas is made, an ash liquefying zone 9 is formed just above a cooler zone 11 on the grate, so that the liquefied ash solidifies in this cooler zone in which an agitating member 5 rotates so as to break up the clinkers before large masses are formed. The clinker is broken up and delivered through a discharge opening 12 to a trough 13 in a driving ring 6, and the zone 11 is enclosed in a water cooled member 15. Steam is admitted through either of inlets 16 or 17 and a gas or a blast outlet is provided at the top, and air or gas' inlets or outlets 18a at the bottom. The upward steam run is sufficiently small and the down-run sufficiently large to maintain the solidifying zone at red heat, and the production of blast gases containing more than 14 per cent of carbon dioxide is avoided by using a shallow firebed. Blast furnace gas may be used in conjunction with or instead of the steam. Reference has been directed by the Comptroller to Specification 336,203.
