Filed: 1961-08-22
Abstract: 972,431. Firebars. STOOKWERK N. V. May 28, 1962 [Aug. 22, 1961], No. 30184/61. Heading F4B. In a furnace grate of the kind having firebars with sloping ribs forming air channels between adjacent bars, the lower nose of each rib is upturned so as to prevent fine fuel sliding away through the air channels. A trough grate is formed from a series of fire bars 1 supported between a bearer 2 at the middle of the furnace and the side walls 3. Each bar 1 has ribs 4 forming air channels between adjacent bars, the ribs on adjacent bars sloping in opposite directions to improve the air distribution. Each rib 4 overlaps the adjacent rib, and the lower nose 7 of each rib extends beyond the vertical line through the upper end of the next rib and terminates in an upward directed extension 8 to prevent fine fuel falling through the grate. The under side of each rib is concave, and the nose 8 forms a Venturi-type constriction in the air passage so as to keep the passages clear of ash or fuel dust. The minimum, width of the air passages decreases from the middle of the grate to the edges. Alternate firebars may have ribs at either side, sloping in opposite directions, instead of each fire bar having ribs on one side only.

Abstract: 763,612. Knitting. GOODRICH CO., B. F. Nov. 4, 1953, No. 30501/53. Class 74 (2). A warp knitting-machine for making carpets or like pile fabrics has two series of yarn guides adapted to traverse over the needles when the needles are lowered, one 24 of which feeds a ground yarn and the other 25 a pile yarn. After each traversing movement of these guides the needles are raised so that the ground and pile yarns extend across the backs of the needles and to receive threads from warp guides 22. The warp threads are then knitted by the needles enclosing between them the ground and pile yarns, the pile yarn being drawn over a former 50 to produce loops which are later cut by an edge 51 on the former as the fabric is withdrawn. The warp guides are subsequently swung down to the rear of the needles so that their threads clear the guides 24, 25 which are thereby permitted to further traverse the needles whereafter the warp guides are raised to again feed yarn to the needles. The cutting edge 51 may be omitted if uncut pile loops are required. The guides 24, 25 are of the form disclosed in Specification 763,613.

Title: Retractable undercarriage for aircraft
IPC: B64C25/22
Filed: 1970-06-26
Abstract: 1320011 Retractable aircraft undercarriage MESSIER 26 June 1970 [27 June 1969] 31171/70 Addition to 1303663 Heading B7G In a modification of the undercarriage of the parent Specification, the slide valve fluid distributer (12) having three positions, which controls the supply of pressure fluid to the jack 23 operating the hatchdoor 16, is replaced by a first distributer 312 which can take up a first position assumed when the undercarriage is fully lowered and a second position assumed at other times, and a second fluid distributer 412 which also has two positions, one assumed when the undercarriage is locked in the retracted position and one when it is not. As well as being suitable for a case when the size of the undercarriage would necessitate a lengthy mechanical connection between the arms (6) and (9) of the original device, the modification ensures that the door is only closed after the undercarriage has been locked in its place. The distributers 312 and 412 are illustrated in their positions when the undercarriage is locked up, unlocked and fully lowered (Figs. 2-4 respectively, not shown). As in the parent Specification, 1,303,663, when the undercarriage is being lowered or retracted the door 16 is held open by the appropriate chamber 233 of jack 23 being supplied from whichever conduit is under pressure by way of spring clapper valves. Alternative embodiments of the present modifications also ensure that the door remains open, despite any fluctuations or failures of the hydraulic system, during movement of the undercarriage. Thus (Fig. 5) chamber 233 is connected directly to pressure line 104 via non- return valve 27 when the positions of modified distributers 512 and 612 correspond to the undercarriage being in motion. Alternatively, Fig. 6, a mechanical lock may be provided, clip 234 on the jack connection rod 231 being held over projection 235 by spring-loaded piston 236 when chamber 232 is not being supplied with pressure fluid. In a further embodiment, Fig. 7 and Figs. 8 and 9 (not shown) chamber 233 is fed with pressure fluid at all times, so as to tend to maintain the door open; when it is desired that the door be closed pressure fluid is fed also to chamber 232, which is of greater cross-section, so that the pressure in chamber 233 is overridden. This modification may also have the mechanical lock already described with regard to Fig. 6.
