Pile support members 13 are now rocked so that shoes 26 thereon move beneath the remainder of the pile 5 above the separated sheet B. The tips 27 of the shoes 26 have slots through which air streams directed above the sheet B issue just before the suckers 10, 11 reach their lowest position, at which position the suction is cut off. The bent-down edge of the sheet B is now engaged by edges 47A on rotating discs 6 co-operating with rubber rollers 8 to feed the sheet to a machine. Suction openings 48 in the discs hold the sheet against the discs.

Abstract: 1478169 Diaphragms FOSTER ELECTRIC CO Ltd 24 Dec 1974 55808/74 Heading H4J A circular diaphragm 1 for an electroacoustic transducer comprises a non-magnetic and insulative membrane on which a conductor is formed. The conductor includes a plurality of parallel conductor parts (as shown the two arms of U-shaped pieces A 1 , A 2 , A 3  ... etc.) and a group of other conductor parts 7, 7<SP>1</SP>, 7<SP>11</SP> ... etc. which interconnect the parallel conductor parts with one another and with terminals 5, 6. A group of additional metal parts 9, 10, 11, 12, 13, 14 is electrically insulated from the conductor. These additional metal parts increase the rigidity of the diaphragm and balance the weight distribution in all radial directions of the diaphragm, thereby inhibiting unwanted resonance frequencies and assisting in obtaining a substantially flat frequency response over a relatively wide range. The conductor is of copper or aluminium and the membrane is of polyimide, polyester, mica or phenol formaldehyde resin. The metal parts 9 to 14 may be formed at the same time as the conductor and may be of the same thickness. Alternatively their thicknesses may be varied. In use the conductor is in a magnetic field provided by the transducer. The transducer may be a microphone, headphone or loudspeaker. The diaphragm is held on a circular frame 8, the terminals 5, 6 being close to the frame 8.

Abstract: 1349443 Recording television pictures ELLANIN INVESTMENTS Ltd 19 Dec 1972 [20 Dec 1971] 58546/72 Heading H4F The production of a comb effect when double interlaced scan video pictures are recorded on motion picture film, which is due to the lateral displacement of a moving object (vertical edge) against a contrasting background during the time interval between an odd-field scan and the interlaced even-field scan which together from a frame on the motion picture film, is prevented by comparing during each even-field scan each line thereof with the preceding even-field line A (comparator 28) and with an adjacent odd-field line D (comparator 40), and by comparing the two odd-field lines B and D adjacent the evenfield line C (comparator 34). If the comparisons show identity between the pair of even-field lines and between the pair of odd-field lines, but a difference between the compared odd and even field lines then selector 44 is actuated to substitute adjacent odd-field information, e.g. a 50-50 interpolation (produced by resistors 45, 47 and clamping amplifiers 49, 51) of adjacent odd-field lines for the even-field line. For all other results of the comparisons the even-field lines are transmitted unchanged. During the odd-field scans all the lines are transmitted unchanged by actuating selector 52 to transmit the output from compensating delay 50 instead of from selector 44. In a basic embodiment each even-field line is compared with an adjacent odd-field line and if there is any difference therebetween an interpolation of the two adjacent odd-field lines or just one of the adjacent odd-field lines is substituted for the even-field line. This basic embodiment does not distinguish between moving vertical interfaces and a horizontal interface. In the recording of a colour video-signal the above processing has to be done separately in  the luminance and chroma channels as the phase of the chroma signal between adjacent line of the same fields requires phase inversion before comparison.

Around this combustion chamber 8 is located a heat protection cover 23, this being inside the cooling cover 7, closed at its upstream end 24 and open at its downstream end 25. The carburettor 19 has, extending into the space between the cooling cover 7 and the heat protection cover 23, a starting air pipe 26 which is connected to the rear 27 of the carburettor 19, the carburettor being supplied with fuel from a container 29, through which a section 11 of the cooling cover 7 passes to support it, the carburettor also having a pipe 31 to return excess fuel to the container 29. The carburettor, which comprises a fuel whirling chamber and a twisting member located in the entrance to the pipe 20 at the carburettor, to ensure mixing of the fuel and air, also has an adjusting mechanism consisting of a diaphragm controlled valve operated by pressure from a by-pass from the pipe 26 which opens the fuel whirling chamber to the atmosphere and stops operation of the carburettor if the blower pressure drops. Another diaphragm controlled valve is situated at the spray liquid inlet 15, this comprising a catch bolt connected to a diaphragm whose pressure side communicates with the combustion chamber 8, a drop in pressure in this chamber withdrawing the bolt and allowing a spring operated valve to close and shut off the spray liquid supply. A further valve in this supply pipe 16 is a three-way valve mounted on top of the cooling cover 7 with an inlet communicating with the inside of this, it being adjustable either to allow the free passage of spray material through the pipe 16 or to shut off this supply and connect the air from the blower to the downstream section of the pipe 16, which air cleans the pipe. The pipe 16 is also separable from the supply tank 17 at a connection 59, which connection has a valve such that the spray liquid does not escape when the pipe 16 is removed. The flexible tube 5 is also separable from the cooling cover 7 by removing a tear-off connection. The ignition of the fuel in the combustion chamber 8 may be by way of an ignition circuit common to that for the combustion motor 2, or may be separate. The apparatus may be carried on the back, the spray being directed manually.
