Abstract: 1,120,084. Gas filters. CAMBRIDGE FILTER CORP. 31 Oct., 1966 [16 June, 1966]. No. 48758/66. Heading BIT. [Also in Division E2] A filter housing, adapted to be located within or to form a section of a gas duct to support one or more deeply pleated filter elements 24-27 thereacross, comprises a downstream peripheral seating frame 42, 48 for each element and upstream clamping means 131-214 whereby elements are urged against frames 42, 48 with which their peripheral gaskets 50- seal. The housing may have a removable access panel 80 on one or both sides, and in the latter case elements are replaced by sliding in on one side while pushing out on the other. Channels (180)- 186 upstream support similarly replaceable prefilter elements. The upper and lower upstream edges of the integral frame 24 of a filter element are engaged by ends 142 of spring-coil levers 131, pivoted at 132, whose other ends are connected by links 152 pivoted to a common frame 166. The frame 166 of each clamp is advanced or retracted by screw 169 whose handle 206 is manually rotated to clamp or release the filter element. In the released position, ends 142 of levers 131 are retracted into their supporting channels 112 12 (Figs. 6, 7, not shown) to facilitate lateral sliding of the element. Handle 206 is retracted (Fig. 5, not shown) before panel 80 is replaced. The housing illustrated accommodates four elements, in two rows separated by a horizontal partition (41). and central stops (254) may define the fully inserted positions of elements, being removable when replacing elements.

Abstract: 1,087,982. Trimming waste material from open-ended containers. MOLINS ORGANISATION Ltd. Nov. 26, 1964 [Dec. 13, 1963], No. 49411/63. Heading B5A. In apparatus for trimming waste material from the open end of a container, the container is held between an outer member and an inner member, both members being provided with cutting edges which can move one over the other to shear waste material successively from the walls of the container. An arbor 1 having a central bore 4, counter-bored at 5, is inserted into the container and a cover plate 9 screwed thereto, leaving a gap to accommodate a knifeedged plate 11 in the mouth of the container, the plate having holes therein through which the screws pass and a central aperture, square with rounded comers, to allow a shaft 6 cranked at 5 to extend through the central bore in the arbor. Rotation of the shaft causes a peg 15 (Fig. 2, not shown) on the crank to move from its initial position in the corner of the square aperture to press against the side of the aperture whereby the knife is pushed outwards and its cutting edge passes over the cutting edge of a sleeve 3 surrounding the container to shear waste material therefrom. There are four cuts in each rotation of the shaft.

Title: Data handling arrangement
IPC: H03M11/02
Filed: 1974-11-15
Abstract: 1487855 Selective signalling GENERAL ELECTRIC CO 15 Nov 1974 [26 Dec 1973] 49550/74 Heading G4H In data handling apparatus, a data source intermittently delivers data groups at different speeds and in occasional overlapping relationship via gate apparatus to a data register, a monitor circuit opening the gating apparatus in response to the presence of overlapping data groups in the register and closing it in the presence of a valid, single data group in the register. In a keyboard unit, actuation of a key at 1 is encoded 5 and passed by gates 6 at an input register 7. If one and only one key is actuated, detectors 11, 12 cease to enable gates 6 via OR 13 and enable AND 19 to pass the next timing pulse 36 from a printer 25 to gate at 8 register 7 to an intermediate register 15, and after a delay of one timing pulse 36 at 21 to produce a pulse from OR 13 which resets register 7 via AND 28 and opens gates 6 for the next keyed character. Presence of a character in register 15 is detected 16 to produce a pulse to printer 25 and set a flip-flop 48 so that the next timing pulse 36 transfers 37 (with addition of start, stop and parity bits) the output of intermediate register 15 (after possible alteration at 35) into a shift register 40 which converts from parallel to serial. The printer 25 provides pulses 42 to sample 43 the data bits into a bit buffer 44 to feed the printer 25. Rollover problems are avoided since the period of timing pulses 36 is less than the interval between successive key actuations during rollover typing.
