Abstract: In an insertion machine a track 20 moves groups of items past feed station 31, 32, 33, 34, 35, 36, 37, 38, 39, during respective machine cycles. The feed stations selectively feed items onto the tracks 20 for inclusion with a group of items and eventual stuffing into an envelope. A master control item 46 fed from station 31 for each group has indicia 50 thereon which provides an indication from which of the feed stations items can be fed. In order for data processor 102 to calculate the amount of postage appropriate for the stuffed envelope, an operator uses a keyboard and display 110 to input predetermined per item weight values for items held at select stations. A data processor 102 uses the predetermined values indicative of the per item weight of items held in the stations to obtain a calculated total weight for each group of items.

Abstract: The invention relates to an apparatus for uniformly filling a container with products such as fruits or the like to a predetermined weight or level, in which apparatus the angular position of the container with respect to the horizontal is changed during filling in response to the instantaneous weight or level of the product in the container. According to the invention, a tongue which can be moved back and forth in substantially horizontal direction is provided below a product supply. The tongue assumes positions in response to the instantaneous weight or level of the product in the container such that the height of drop of the products into the container is kept at a minimal during filling and the container is filled uniformly.

Abstract: The invention relates to a method of sorting and bundling flowers, comprising hanging the flowers separately in individual flower supporting members circulating in a first closed path; as they are traversing the path, designating the flowers as to at least one characteristic, such as stem length; depending on the designated characteristic, transferring the flowers to second flower supporting members circulating in a second path; grouping the flowers into groups of a limited number of flowers; and collecting and bundling a series of groups into a bunch. The individual flower supporting members are moved adjacent a transfer point from a transport position into a transfer position in a tract substantially perpendicular to the first path, while during transfer the second flower supporting members are held stationary and oriented in the direction of movement of the individual flower supporting members. The invention further relates to apparatus for applying this method.

Abstract: A bung plug assembly (30) for a clamshell life-raft canister (14) comprises a tubularly-shaped housing (32) for holding wound, or coiled, rope (84) with a resilient grommet cap (34) on an outwardly-directed end (64) thereof and a resilient rear cap (36) on an inwardly-directed end (66) thereof. The resilient grommet cap defines a grommet-cap bore (40) therethrough through which an outer-end portion (50) of the rope extends and a canister slot (72) for receiving edges of top and bottom halves (16, 18) of the canister as well as a key slot (46) for receiving a resilient molded key (44) to engage an edge of at least one canister half. A bung plug (38) having a rope passage (42) therethrough for receiving the outer-end portion of the rope is inserted into the grommet-cap bore.

Abstract: A sheet of work-hardenable, non-heat-treatable, corrosion-resistant steel is cold rolled into a tube (12) and welded (10). The cold rolling strengthens the material. The welding causes the weld area (10) to revert to its annealed condition, but the ends (24, 30) of the tube (12) are then swaged into open domes (14, 16) to form a symmetrically-swaged tube having further work-hardened ends which overcome the apparent weakness of the weld (10). A spherical disk (20) is then welded on to one end to form a bottom and a port section (26) is welded on to the other end to complete the bottle construction.

Abstract: This method for establishing the pressure-diameter relationship of an artery employs the measurement results from a non-invasive sensor (3) of the artery diameter, for instance of the humeral artery, and from a non-invasive sensor (4) of the blood pressure applied for instance to the end of a finger. The measurement locations being separated by a distance .DELTA.x, the method provides for the correction of the pressure measurements as if such measurements had been effected at the location of the diameter measurements. The method further provides a correction which takes into account the mechanical properties of the artery, defined by the parameters .alpha., .beta., .gamma., . . . and which are calculated, if necessary by successive iterations, until the pressure-diameter curve appears free from all measurement anomalies (hysteresis).
