Inventor: GLASS EMMETT F
IPC: A01D34/14
Filed: 1991-04-24
Abstract: A reciprocating cutterbar of the type utilizing a pair of counter-reciprocating sickles driven at the opposing outboard ends and overlapping at the inboard ends thereof is disclosed wherein the knife sections are detachably affixed to the respective support bars of these sickles by special threaded fasteners to permit the overlapped knife sections to maintain a close shearing relationship. These special threaded fasteners include a head portion adapted to be countersunk into the body of the knife section below the surface thereof, a threaded portion adapted to be threadably engaged with a nut to effect a clamping load between the knife section and support bar, and an intermediate portion having a non-circular cross-sectional configuration engageable with a corresponding non-circular opening formed in the support bar to restrict rotation thereof when the fastener is engaged therewith. The head portion of the fastener includes a chamfered surface engageable with a corresponding chamfered surface surrounding the hole through the knife section to permit the fastener to firmly engage the knife section while being countersunk therein.

Abstract: ABSTRACT            The invention concerns a table (T) to facilitate the preparation and exchange of upper (S1; S'1) and lower (S2; S'2) tools of a blank separating station in a package producing machine.  To this end, the table (T) is able to pivot around a horizontal axle (A1) and is designed to carry two pairs of tools (S1, S2, S'1, S'2 respectively).  When a pair of tools (S1, S2) has been put to operation in the station (S), the other pair (S'1, S'2) can be prepared on the table (T) for the subsequent run.  The two tools (S'1, S'2) of a same pair are arranged on the table (T) so that the lower tool (S'2) after having been prepared may serve as reference for the positioning of the blank separating punches (P') on the upper tool (S'1).

IPC: G03F3/10
Filed: 1991-06-03
Abstract: Abstract The invention refers to an apparatus for testing the color separations of a multicolor print, comprising a pair of press rollers being mounted in a frame and constituted by rollers which can be lifted off each other, through the roller gap of which an image-bearing element consisting of a support foil with an exposed, photosensitive layer, with a color foil, consisting of a color-bearing foil with a color layer, being placed on this element, is fed such that portions of the color layer adhere to the tacky areas of the image-bearing element. For the solution of this problem to provide an apparatus of said kind by which the testing of the color separations of a multi-color print can be carried out in a simple and rapid manner, a movable frame is provided in which a plurality of pairs of roll bearings for rolls to be unwound and wound up are mounted. A roll bearing for each pair of rolls allows a roll of a color foil web to be loaded, and the color foil web can be wound up on a roll carried in the other roll bearing. The web section of the color foil web between the rolls of a pair of roll bearings runs in between the press rollers of the pair of press rollers.

Abstract: The invention relates to security means for securing the sequential order of the pages of a book such as a passport, or other such security document, by enabling the convenient detection of any removed  pages  through  a visual  inspection  of  the  book.          Specifically, the invention provides a means of marking the unbound vertically aligned edges of the pages of a book whereby any subsequently missing page(s) may be detected upon a visual review of the unbound side of the book.  The tamper-proof book comprises a plurality of pages positioned one over another, a spine securing the first sides of the pages, the sides of the pages opposite the spine being vertically aligned to form a vertical side opposite the spine, and visually detectable markings on each one of the pages at the vertically aligned sides.  The markings collectively depict a visual image across the vertical side such that the absence of any one of the successive pages is identifiable upon viewing the image.          Preferably,  the  markings  are  printed  by  means  of  invisible fluorescent ink.

Abstract: A sifting drum which features sifting bars mounted along a cylindrical surface in parallel to the central cylinder axis, with the spaces between sifting bars forming the sifting gaps. The sifting bars are held by supporting rings in an axially equidistant configuration circumferentially to the cylinder circumference in peripherally open recesses in the supporting rings. The invention is characterized by the sifting bars relative to the sight line having lateral surfaces in a direction radial (V) to the sifting drum. At least one of these lateral surfaces in inclined by an angle away from the radius (V), resulting in a conicity between the two lateral surfaces of between 14 and 35° which corresponds at least to a major extent to the corresponding lateral surfaces of the supporting ring recesses. Consequently, when supporting bars of the appropriate length are transformed into supporting rings, the sifting bars are clamped into the supporting rings at these points, with at least one of the lateral surfaces of the sifting bars having at least one projection or one cutout corresponding to an opposing cutout or projection, as the case may be, in the recesses of the supporting ring.

Title: Food rethermalizing and satelliting tray
Inventor: DEGROW GARY C
IPC: A47J39/00
Filed: 1990-08-14
Abstract: A food service rethermalization system including a tray (100) having first and second receiving hot dish receiving areas (120, 122) at least one cold dish receiving area (124, 126, 128) and an end wing area (132) for holding eating utensils, napkins and the like. First and second selector or actuator knobs (102) are mounted in the tray (100) adjacent to the first and second hot dish receiving areas (120, 122) respectively, and can be separately turned to on or off positions. When the tray is inserted in a rethermalization cart and the first and second heating pods of the cart are at the first and second areas respectively, the heating pods whose associated knobs are in the "on" position are switched on and the food at the associated areas thereby heated in a programmed manner. After the knobs have been turned as needed and before the tray is inserted in the cart, an over-all insulated cover is secured to and on top of the tray. The cover thermally separates and covers the different areas including the wing area. It thereby covers, insulates and protects each of the areas allowing the loaded tray to be safely transported outdoors to a remote building or other location.

Abstract: A  method  of  controlling  the  operation  of  a packet switched CDMA telecommunication network for controlling the operation of transmitters and receivers.  The terminals of network users (Ui,j) communicate with other terminals (Uj, i) via a CDMA channel,  and the terminal of each user is assigned a receiver code (ri,j) and a transmitter code (ti,j) used by the terminals for encoding packets to the other terminals of the network. To improve the performance of the network, the terminals sense the channel for the presence of the receiver codes (ri,j) and/or the transmitter codes (ti,j) at the different stages of the connection establishment, and the trans-mitting terminal  (TERi)  transmits encoded re-quest packets (REQ) and data packets (DAT) to the channel on the basis of the sensing proced-ure, and the other communicating party, i.e. the receiving terminal (TERj), receives said encoded packets  and  transmits  encoded  acknowledgement packets  (ACK)  and  busy  tone  packets  to  the channel.
