Abstract: A heated glass sheet topside support device (22,22',22a,22a') is disclosed as including horizontally extending lower and upper plates (38,46) connected by a set of vertically extending passage members embodied by tubes (54) or plate members (54a) to define passages (55,55a,55a'). The support device also includes first and second manifolds (56,58) for supplying pressurized gas and a vacuum through first and second sets of holes (42,42a,42a';44,44a,44a') in the lower plate so as to thereby support a heated glass sheet below the lower plate without any engagement. In one construction, the pressurized gas is supplied through a chamber (48,48a) between the plates through a set of shorter tubes (80,80a) mounted within the first set of holes (42,42a) in the lower plate (38,38a), and the vacuum is drawn from the upper side of the upper plate (46,46a) through the holes (52,52a) therein and through the passages (55,55a) and the second set of holes (44,44a) in the lower plate. In another construction, the vacuum is drawn through the chamber (48,48a') between the plates through the first set of holes (42,42a') in the lower plate (38,38a'), and the pressurized gas is supplied through the holes (52,52a') therein and through the passages (55,55a') and the second set of holes (44,44a') in the lower plate. Each embodiment of the topside support device is supported by fused silica posts (86) that preferably have upper ends including inverted cup-shaped members (102) on which the topside support device is slidably mounted by an associated spherical bearing (106). Positioners (118) for the silica posts (86) and support device locators (134) cooperate in supporting and positioning the topside support device at the proper location.

Abstract: A tool having two side rods spaced apart by a connecting crossbar facilitates clamping and unclamping a cable in a groove on an insulator cap. To clamp the cable, the crossbar is inserted into a first recess on the cap between the groove and a protruding stud, and the side rods are pressed against a front branch of a clamp wire pivotally mounted on the cap to snap the front branch into a second recess below a front guide surface on the stud. To unclamp the cable, hooked extensions of the side bars engage the front branch of the clamp wire and lift it out of the second recess when the crossbar is pressed against the front guide surface of the stud. Separate clamping and unclamping tools can be mounted on an insulating handle for pivoting between a rest position and an operating position and spring biassing means can be provided to urge each tool toward a rest position.

Abstract: A conditional replenishment video data transmission system involves the transmission of digital values representing the brightness changes at picture elements of a raster scanned image since the previous frame. Since nothing is transmitted for those picture elements without a significant brightness change, the amount of data to be transmitted will depend on the extent of movement in the image, and buffer stores are provided to allow the use of a constant transmission rate. If the extent of movement in the image is very high the buffer store at the receiver will tend to fill up and might overflow. In order to avoid this occurring, reduction of the amount of data to be transmitted by element subsampling has been proposed in which in a cluster of changing elements data relating to only some, for example alternate ones, of the elements are transmitted, and interpolation is used at the receiver to calculate the brightness change data for the omitted elements. The blurring of vertical edges in the image resulting from the interpolation is avoided by suspending sub-sampling where vertical edges are detected in the image. When in the sub-sampling mode, in order to avoid having to mark those normally omitted elements for which data are transmitted the receiver is arranged to detect the presence of a vertical edge and respond by treating the data as if they relate to all elements in the vicinity of the edge and not just the sub-sampled ones. Transmission error can result in the receiver being incorrect in the detection of edges, and to avoid this the number of quantizing levels during sub-sampling is reduced from 8 to 4, using one set of 4 codes for the normally present elements and the other set of 4 codes for the normally omitted elements. Since a vertical edge will usually appear in more than one line, the receiver may be arranged to check the previous line for a vertical edge and anticipate the inclusion of normally omitted elements if such an edge has occurred.

Abstract: A pressure diffuser (10) includes in a liquid-tight pressurized vessel (12) a vertical screen (24) which defines with a vessel wall (14) first and second interior volumes (26, 29) for transmitting pulp from a pulp inlet to a pulp outlet and receiving displacement (e.g. wash or bleach) liquid transmitted from headers (28) through the pulp. The screen ends around housing members (20, 22) have different cross-sectional areas, and quick movement of the screen effects backflushing. The volumes (26, 29) are segregated by the vertical, generally cylindrical, screen (24). A chamber (42) is provided in communication on opposite sides of a piston (44) therein with the pulp adjacent the pulp inlet (16), and the extracted liquid (in 29). By displacing the piston with a cylinder (50) immediately prior to rapidly moving the screen vertically with a hydraulic cylinder (50) to effect backflushing through the screen, the pulp pressure on the screen is reduced and at the same time shocks and compaction of the pulp adjacent the inlet caused by the movement of the screen are avoided.

Abstract: A conveyor belt of elastic material comprises a planar central part (2), two planar edge parts (3, 4) and two hinge parts (5, 6). The central part is flexurally rigid about the longitudinal axis of the belt (1) by means of a transverse reinforcement (8, 9b) and has a low extensibility in the longitudinal direction by means of a longitudinal reinforcement (10). The two planar edge parts (3, 4) are each hingedly connected with a side edge of the central part and flexurally rigid about the longitudinal axis of the belt by means of a transverse reinforcement (8, 9a, 9c). The edge parts are further extensible in the longitudinal direction of the belt and have a total width which is at least equal to the width of the central part. The two hinge parts (5, 6) connect each edge part with the central part and are flexible about the longitudinal axis of the belt and extensible in the longitudinal direction of the belt. The hinge parts are further resilient for pivoting the edge parts out from a position folded towards the central part, and have a substantially smaller width than the central part. The belt conveyor in which the conveyor belt (1) is included, further comprises support rollers for supporting the belt, and guide means for maintaining the desired shape of the belt. The guide means comprise pressing means which, against the spring action of the hinge parts, hold the edge parts in the desired position relative to the central part.

Title: Inflatable rescue ramp
Inventor: LEBLANC GEORGE W JR
IPC: A62B1/20
Filed: 1990-09-05
Granted: 1994-07-26
Abstract: ABSTRACT     The invention provides an inflatable rescue ramp hav-ing a pair of spaced inflatable tubes which join at one end to define a bow.  A flexible web is mounted between and connects to the tubes at outside seams.  That is, the web passes under each tube and is attached thereto on outside longitudinal seams, such that downward pressure on the web or ramp floor will cause adjacent portions of the tubes to axially rotate outwardly from each other to provide and enhance passageway on the web between the tubes.  The rescue ramp is carried to the scene in a folded and compact state, with the above tubes being con-nected to a compressed air source.  The rescue ramp is positioned on or near a firm surface and pointed toward a victim on an unfirm surface e.g. in an icy pond and the tubes inflated causing the ramp to pop or snake out of its packed condition and extend toward the victim with anchor lines from the tubes trailing.  The rescuers grab the anchor lines and aim or position the inflating or inflated rescue ramp in the direction of the victim and then secure the anchor lines and the near end of the res-cue ramp on or near a firm surface e.g. the shore of a pond, whereupon a rescuer can hurry out on the so-positioned ramp to aid the victim.  Subsequently, the rescue ramp is deflated, folded and packed for future use.
