Title: Staggered scan facsimile
IPC: H04N1/413
Filed: 1966-01-03
Abstract: 1,127,048. Television; copying by scanning. XEROX CORP. 3 Jan., 1966 [4 Jan., 1965], No. 203/66. Heading H4F. To improve the image quality in a time and amplitude quantized facsimile or television system the transitions in different lines of transmitted video is synchronized to different clock signals having a common frequency but different phase, so that when reproduced the signals create marks which no longer line up in vertical rows i.e. the black-white transitions are staggered or offset from line to line. The video signal may be amplitude quantized in two steps, e.g. black and white, or more than two steps, and although preferably the transitions in alternate lines are offset by half the normal spacing between transitions the staggering may be such that only every third line is vertically aligned or the transitions in individual lines may be positioned in a random fashion. Since a staggered signal which changes in phase from line to line is not suitable for transmission over most communication links the signal before transmission is preferably passed through a variable delay circuit wherein the phase of the signals is altered to bring them into synchronism. Instead of synchronizing the sweeps of the transmitter and receiver to the clock reference and altering the phase of the signal derived from or supplied thereto as described in the detailed embodiment, the stagger may be introduced by altering the phase of the scanner or recorder sweeps with respect to the clock reference or by stepwise operation of a scanner.

Title: Improvements in or relating to apparatus for vacuumizing, gassing and closing containers
IPC: A23L3/00
Filed: 1948-01-06
Abstract: 655,622. Food canning. CONTINENTAL CAN CO., Inc. Jan. 6, 1948, No. 449. Convention date, Dec. 20, 1946. [Class 49] An apparatus for vacuumizing gassing and closing containers comprises in combination a vacuumizing and gassing machine A, a closing machine B, means for feeding filled containers and closures into the vacuumizing and gassing machine, means for gradually drawing a relatively low vacuum in a first stage in the vacuumizing machine, means for drawing a relatively high vacuum in a second stage in the vacuumizing and gassing machine, the said closures having provision for engaging in and effecting a temporary friction closure of the containers and means of bring- ing this about so as to avoid disturbing the vacuumized and gassed condition in the containers as they are being fed from the vacuumizing and gassing machine into the closing machine to be perma- :nently sealed therein. As shown, containers 64 are fed on to a disc 137 and are presented to the screw 142 which times them on to the chain 144. The containers move past a cam 192 which when no container passes operates to prevent covers 62 which otherwise are fed by the mechanism D on to the containers which have passed into the pockets of a turret 150 which diverts the containers and covers on to pads 51 of the vacuumizing and gassing machine turret 12. The pad is lifted into position to seal the container treating bell 53 with the container and cover therein loosely assembled (Fig. 4). A chuck 73 is then lifted to free the fingers 78 and permit them to lift the cover 62 from the open top of the container 64. With the cover held above the open top of the container a port 117 comes into communication with a port 107 through which a low vacuum is drawn in the container. The port 117 next passes into communication with a high vacuum duct 109 to effect completion of vacuumization. The port 117 next passes into communication with a gas duct 112 through which the container is gassed. After the vacuumizing and gassing is completed the chuck 73 is forced downwardly causing release of the cover by fingers 78 and a temporary tight friction assembly as the lower heel portion 63 is forced into the container. Thereafter the pad 51 is lowered and the temporary closed container is transferred by a turret 164, guide 165 and turret 167 from the vacuumizing and gassing machine to a closing turret 168 of the closing machine. A control 194 operates to close a valve 120 to prevent vacuumizing and gassing when no container is present. U.S.A. Specification 1,752,912 is referred to.

Title: Valve mechanism for a condensate trap
Inventor: SHAW EDWIN C
IPC: F16T1/30
Filed: 1955-01-10
Abstract: 774,561. Steam traps. PERFECTING SERVICE CO. Jan. 10, 1955, No. 685/55. Class 64(2) [Also in Group XXIX] The discharge orifice 46 communicating between a discharge chamber 25 and a chamber 11 of a steam trap, e.g. containing an inverted bracket or float 12, is closable by a main valve 47 having a pilot orifice 50 therein closable by a pilot valve 51, these valves being secured to levers 53, 54 respectively which are operated by the trap operating member, i.e. the bucket or float 12. An L-shaped member 77 riveted to the bucket top hooks loosely over a portion 82 of the pilot lever 54 to pull it down when the bucket drops and has a tab 84 which engages and lifts the lever 54 when the bucket rises. The lever 54 is pivoted to the main lever 53 by a bail 60 to which the main lever itself is also pivoted near the ends 61 of the bail which are journalled in lugs 63 formed at the end of a U-shaped bracket 55 embracing the orifice 46. At opening or closing, the pilot valve 51 moves first, e.g. opening until the free end of the main lever 53, fitted freely in a slot 71 in the pilot lever 54, is contacted as shown in Fig. 5 when the main lever is then also tilted, and the levers descend together. On closing, the slot 71 permits closure of the pilot orifice 50 by raising of the lever 54 before the main lever is pushed up. By this means a small amount of consensate may be discharged from the main chamber 11 without operation of the main valve, or internal pressure may be dissipated so that the main valve may operate more quickly and with less accumulation of condensate. The inlet to the main chamber 11 leads to the open mouth of the bucket 12 so that condensate entering the trap enters the bucket and by lowering its buoyancy causes the bucket to fall and one at least of the valves 51, 47 to open; the entry of steam or gas has the opposite effect by displacing condensate from inside the bucket. Air preceding the condensate passes through a vent 12c. With condensate absent, steam or gas pressure holds the valves closed. At the bottom of the main casing a blow-off ball valve is held to the closure up against its seat by a tube having a bore which is tapered and of elliptical or rectangular section so as not to be closed by the ball. The tube is screwed into a hollow plug screwed into the chamber base and loosened when blowoff is required.
