Title: Label printing and dispensing apparatus
Inventor: VAN OCKER WILLIAM
IPC: B65C9/46
Filed: 1989-11-29
Abstract: ABSTRACT OF THE DISCLOSURE         A label printer and dispenser web transport system includes a motor driven platen and a print head resiliently directed against the platen between which an ink foil and label web are passed.  The web travels over a triangular peeler bar disposed closely adjacent the platen and is then returned to the platen for passage between the platen and a spring biased idler roll deformably engaging the platen to maintain web tension over the peeler bar.  The print head is pivotally mounted and is moved out of engagement with the platen when the print head is not printing. The ink foil is not advanced when the print head is moved away from the platen.

Patent CA-2014107-A1 (CA)
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1990-04-06
Abstract: ABSTRACT This invention relates to an improved cryogenic separation process em-ploying a single pressure distillation column for the recovery of low purity, high pressure oxygen. The process uses two working fluids, i.e., high pres-sure air and high pressure nitrogen to effect reboil in the column. Both the condensed air and nitrogen streams are fed as reflux streams to the distil-lation column. The use of nitrogen reflux enhances oxygen recovery by enhancing purity of the nitrogen from the column.

Abstract: A personal computer has two memory banks (12,14) respectively connected to two parity check units (16,18) operative to detect parity errors. Upon doing so, each unit (16,18) feeds a parity error signal to a separate latch (22,24). The latches (22,24) are connected to a logic circuit (26) which is in turn connected to an interrupt controller (34) that initiates an interrupt (36) when a parity error occurs. One latch (22) is further connected to a check bit (41) of a register (40) of an I/O port (38) and the check bit (41) is set by the one latch (22). An interrupt handler reads the register and provides messages indicating which memory bank (12,14) caused the parity error.

Abstract: A landfill site is adapted to collect leachate seeping from landfill. A liner impedes passage of liquids between the landfill and a subjacent stratum.A leachate collection layer formed of drainage material is located between the liner and the landfill.  Apertured conduits embedded within the drainage material convey the leachate to a pair of subsurface gallery extending along opposite sides of the site and accessible from the surface.  Each collection conduit has a discharge end extending through the gallery sidewall where leachate flows can be inspected and obstructions in the conduit can be removed.  A groundwater gallery is constructed below the liner in the subjacent stratum and is also accessible from the surface.  Blind-ended slots in the upper surface of the stratum are filled with drainage material.  Apertured groundwater collection conduits in the slots convey groundwater into the interior of the gallery.  The floor of the site is saddle-shaped to encourage leachate and groundwater flows towards the galleries and flows within the galleries to low-points where sumps are located.

Patent CA-2027401-A1 (CA)
IPC: B41F7/26
Filed: 1990-10-11
Abstract: An improved lithographic dampener of the type having continuous plate/form roller/metering roller contact, adaptable to a variety of press configurations and operating speeds, employs a friction-driven oscillator roller that distributes added dampening liquid and the ink/liquid emulsions on the metering roller, to avoid continuing patterns which might cause ghosting in printed images. The dampener has a simple drawer-like configuration, with an open front for improved range of form roller/plate contact. A pan with a remote supply of dampening liquid, is located under the rollers such that the metering roller surface contacts and picks up liquid from a pool in the pan. Simplified seal dams at the ends of the form/metering rollers' nip keep the reservoir of liquid in that nip, yet minimize wear of the seal configuration. A slide block mounting of the metering roller and oscillator rollers allows independent adjustment of pressure at the form/metering rollers' nip, and at the metering/oscillator rollers' nip.

Title: Labeling machine
Inventor: BRATSCHI MARCEL
IPC: B65C11/00
Filed: 1990-11-30
Abstract: Abstract The stepping motor (11) of the label dispenser is directly coupled to the drawing roller (7) which brings about the feed of the carrier strip (1) containing the labels.   In order to keep the driving shaft of the stepping motor and the drawing roller (7) free never-theless from the undesirable resonance phenomena caused by vibrations of the motor armature, the driving shaft (12) of the motor (11) is directly coaxially coupled to the drawing roller (7) by means of an interposed elastic damping member (21).      The damping member (21) has four through-holes (22), into which the driving pins (14, 15 and 19, 20 respec-tively) of the driving plates (13 and 18 respectively) on the motor side and the drawing-roller side protect.      The direct drive is more favorable in terms of cost than the known toothed-belt drive and nevertheless keeps the drawing roller absolutely free from resonance pheno-mena.   Moreover, the type of drive described permits higher labeling rates to be achieved.            (Figs 1 and 2)

Abstract: TROLLEY-POLE PULL DOWN METHOD AND APPARATUS                 ABSTRACT OF THE DISCLOSURE           A trolley pole retrieval method and apparatus. A sensing circuit senses threshold values of voltage and continuity in the vehicle power supply circuit, the vehicle motion and the distance travelled.  The system responds to the sustained simultaneous conditions of low voltage and open circuit in the power supply circuit while the vehicle is in motion by enabling a distance counter. If the vehicle remains in motion under conditions of low voltage and low continuity for a predetermined distance, trolley pole dewirement is assumed and a retrieval pulley is actuated to return the trolley pole to the vehicle. This prevents damage to overhead power lines.        SPECS/BCT3573.02
