Abstract: 1,251,441. Filter. M. PICARD. 22 Jan., 1969 [22 Jan., 1968], No. 3637/69. Heading B1D. A series of filter elements 10 arranged around a pitch circle, or successive sections of a single cylindrical filter element divided by partitions, are cleaned by reverse flow as nozzle 17 moves into line with each in turn and filtrate is forced back from cylinder space 18 as piston 14 is moved to the'right, compressing spring 15, by the pressure of filtrate in the space outside cylinder 13, by virtue of the space 27 being opened to atmospheric pressure by valve 16 and of the two sides of piston 14 exposed to liquid pressure being of different areas. The movement of the piston, to which is connected a bar (24) (Fig. 3, not shown) switches valve 16 over to connect the space 27 with the filtrate space (Fig. 2, not shown), and spring 15 then returns the piston leftwards. The lower end of bar (24) engages a ratchet system whereby the cylinder 13 and nozzle 17 are rotated to align with another element 10 each time piston 14 moves leftwards. During this movement, space 18 is refilled with filtrate from the element which has just been cleaned and from the adjacent element to be cleaned. Bar (24) reverses valve 16 again at the end of the piston's leftward stroke, so the piston movement is continuously repeated at a rate limited by a valve connected to outlet 6, through which filtrate is ejected from space 27 to the same filtrate storage tank as main outlet 3 connects to. On removal of cover 5, the cylinder 13 and elements 10 on their tube plate 7 are lifted out, apertures 9 serving as gripping holes. Elements 10 may be wire wound as a double coil on a support tube or frame.

Abstract: 1,257,124. Automatic exchange systems. SIEMENS A.G. 1 Oct., 1969 [2 Oct., 1968], No. 48140/69. Heading H4K. In a TDM systemhaving 4-wire highways between exchanges, the time frames on all the incoming pairs to any one exchange are synchronized to each other as also are the frames on all the outgoing pairs, the latter frames being delayed by a period tv relative to the incoming ones. Time slot interchange is effected by delaying a channel in one direction through an exchange by a time tx and by delaying the corresponding channel in the other direction by a time ty such that tx + ty = 2tv.  In Fig. 1 mutual synchronization of the incoming pairs Aan1, Aan2 to exchange A is effected by delay devices Vab and Vac, the other incoming highways and the outgoing highways being similarly synchronized by devices not shown. In Fig. 2a it can be seen that a time frame T on incoming pairs Aan1, Aan2 leads the corresponding frame on outgoing pairs Aab2, Aab1 by a time tv. An incoming PCM channel, depicted by a single pulse on Aan1 is delayed by a time tx before it is relayed along an outgoing pair Aab2 in the required direction. In the opposite direction, the corresponding channel is delayed by a time ty between incoming pair Aan2 and outgoing pair Aab1. As already mentioned tx+ty=2tv. The dotted pulses indicate the case when tx=2tv and ty=0. The delay may be effected by devices Vab etc. or by separate store pairs (one for each direction) having a total delay of 2tv. Since there are inevitably some channels which cannot conform to the above rule these are handled by stores having a delay of T+2tv (Fig. 2b, not shown). Overall the number of long-delay stores required is very small. Since the short-delay stores may be utilized more than once in a frame, the total number of stores required is much reduced compared with previous time slot interchange systems.

Abstract: 1288495 Sheet forming; cutting apparatus INTERCAN SA 13 March 1970 [13 March 1969] 12165/70 Headings B4B and B5A [Also in Divisions B6 and B8] In a method for producing containers having externally reinforced walls, a strip of reinforcing material is forced into a loop, the loop inserted into a female mould, and a heat softened sheet drawn into the mould into contact with the loop. In the illustrated embodiment, a sheet 3, drawn from a roll, is passed under a heater 4 to a moulding station 5 at which it is plunger assisted blow formed into a series of female moulds 6, which can be cylindrical as shown, or which can be frusto-conical (see Fig. 10, not shown). The moulds are carried by a vertically reciprocable carrier 18 and are pivoted at the lowest position of the carrier, by means of a jack 19, into a horizontal attitude in which they receive looped reinforcing strips from device 10. The device 10 comprises a series of cavities 16, one for each mould cavity, each cavity being provided at its lower side with a slot 15, through which the leading ends of a reinforcing strip 11 is fed by rollers 13-14. The strip curls around the inner surface of the cavity to form a loop, the loop being severed from the rest of the strip by a reciprocating blade located at the slot, and introduced into the mould by a reciprocable member 12. After the loop is introduced into the mould it is retained there by vacuum and the moulds are re-oriented to a vertical position and raised to the moulding station at which the sheet is drawn into the moulds. The reinforcing strips 11 are formed from a single sheet 20 by a cutting mechanism 22, the individual strips being directed to the device 10 over upper rollers 24 and lower rollers not shown. The cutting mechanism for sub-dividing the sheet 20 into strips 11 preferably consists of a lower roller 47 having grooves the vertical faces 48 of which co-operate with the vertical faces 49 of corresponding ridges formed on an upper roller 50. Where the moulds are not cylindrical it is necessary for each loop to be formed from a curved strip and this is done by a reciprocating cutting die having suitably shaped blades. Possible patterns of cuts are given in Figs. 9, 11 and 12 (not shown).
