Abstract: 1302004 Injection moulding bearings TUTHILL PUMP CO 29 June 1971 30453/71 Heading B5A [Also in Division F2] A bearing assembly having a swivel member 16 in an opening in a housing member 10 is made by placing the swivel member within the housing, introducing hardenable bearing material between the two members and reciprocating the members relative to one another while the bearing material hardens so as to provide a clearance between the swivel member and the bearing surface of the material. The housing member 10 is held by two mould portions 34, 36 and the swivel member supported in the opening in the housing by two movable portions 76, 78. The housing has two passages 33 which allow communication between the space between housing and swivel members and passages provided in the mould portions. Plastics bearing material is introduced into the space through the passages 33, 64, 62, and having filled the space excess material overflows through the passages 66. While the material hardens, the swivel member is reciprocated by the portions 76, 78, which are forced downwardly by a lever (106) (Fig. 7, not shown) acted upon by an eccentric (112) and return under the action of a spring 84. When the material is hard, the upper mould is removed and the spring 84 forces the bearing assembly upwards, the plastic material at the ends of the passages 33 being severed by the wall 38 of the lower mould. The assembly is ejected from the mould by raising the plate 50 which lifts pins 56, thereby unseating the sprues 66.

A photo-electric cell may be provided for measuring the luminance of the screen 12 and controlling the tubes. In another embodiment (Figs. 3, 4, not shown) the tubes are again divided into two groups and the tubes of each group are fed in series. As described, the transparency is a radiographic image in the blue-cyan colour range. Pivoted coloured reflecting surfaces may be used to produce the required colour variation at the diffusing screen.

The pile warps can be shogged at each pick over one or more pile wires sideways, or from one pile wire to the next adjacent in the same direction for a number of successive picks. Inserters 22 and 23 are needles inserting loops of weft. The pile yarn guides 95 and 96 are attached to blocks 101, 102 provided with keys 102 103 which may be positioned in upper or lower keyways 107, 109 and 106, 108 in the guide bars 104, 105. Guide bars 104 and 105 are slidable on a common rod 116 and are connected by arms 120 and 125 respectively to a tubular sleeve 121 and an inner coaxial shaft 123. The rows of guides 95 and 96 are shogged relative to each other by a pattern chain (157) Fig. 4 (not shown) carrying two rows of lugs of various heights according to a pattern, which, chain is reciprocated so that the rows of lugs act on the respective ends of shaft 123 and sleeve 121 to slide them relative to each other and the warp pattern mechanism are provided on both sides of the loom. The yarn guides are lowered into and raised out of the shed by an arm 133 reciprocated by a crank arm (134) Fig. 3, (not shown) fixed to reed rocker shaft (72). Pile wires 24 are controlled via cables (84) Fig. 1 (not shown) by a pattern mechanism (85) which may be a Jacquard, so that they may be selectively pulled out of the weaving zone. The pile wires (Figs. 16-19, not shown) may have portions of different height so as to produce different depths of pile, and may have a blade integral therewith. Loops of weft are inserted simultaneously in superposed sheds between upper and lower ground warps C 1 , C 2  and stuffer warps 5. One of the sets of pile warps may be floated for a number of picks, and to hold it in place on the underside of the fabric, the other set of warps instead of being shogged each pick over the same pile wire may be shogged to the adjacent wire every few picks to form a binder under the floating warp (Fig. 20, not shown).

Title: Multiple tray rotary paper feed system for an image reproduction machine
IPC: B65H3/44
Filed: 1992-06-24
Abstract: A paper feed system for an image reproduction machine, representatively a printer, has a shelf member (44) disposed within the machine housing and rotatably carrying a turntable (76) on its upper side. Two transversely oriented pairs of diametrically opposite upper and lower paper trays (136,138;100,102) are removably supported on the turntable, with portions of the upper trays overlying the lower trays. The turntable may be rotated to vertically interpose a selected one of the four trays between a stationary picker roller (36) and a lifter structure (140) positioned beneath the picker roller. The lifter structure has a portion which moves upwardly through a shelf opening, and a turntable opening aligned therewith, to engage the selected tray and lift it toward the picker roller to bring a paper stack held in the tray into engagement with the picker roller which operates to successively remove sheets from the stack and deliver them to the machine's paper feed path. The lifter structure may then be lowered to return the selected tray to its initial position on the turntable and permit another tray to be selected for rotation into a position from which it may be lifted to the picker roller. When a lower tray is selected, a shift mechanism (122-126) is operated to move the upper trays out of the lift path of the selected lower tray. The trays may be accessed by operating a drive motor (54) which drives the turntable shelf horizontally outwardly through a housing side wall access opening. <IMAGE>
