Title: Feeding of offset, collated forms
Inventor: RING ROBERT S
IPC: B65H20/00
Filed: 1993-10-28
Abstract: ABSTRACT OF THE DISCLOSURE          During the feeding of offset continuous collated business form webs to the slow rollers of a burster, it is important to insure that the top web properly passes through the slow roll section.  By providing a number of puller wheels having aluminum cores and sawtooth rubber coverings atop conveyor belts passing over crowned pulleys which are oversped relative to the web speed, proper feed to the burster is provided.  Form deflecting fingers extending from the puller wheels to the burster also help.  In order to prevent the conveyor belts from running off the crowned pulleys an aligner is provided which has a number of vertical dowel pins with plastic sleeves covering and rotatable with respect to the dowel pins, disposed on each side of a conveyor belt associated with a crowned pulley and puller wheel.  The aligner is provided immediately upstream of a rubber covered drive roll for the conveyor belts.

Title: Apparatus for collection and transfer of particles and manufacture thereof
Inventor: POLK LEWIS T JR
IPC: G01N1/00
Filed: 1993-02-24
Abstract: A device for collecting particles, such as human cells, from a fluid sample, and for transferring the collected particles to a receiver, such as a glass microscope slide, provides substantially exact replication of the spatial distribution of the cells on the collection device. The device supports a surface-collecting filter on a tubular rim, with a precise degree of flatness, and fastens the filter in place at a mounting shoulder recessed below the rim. Distortions of the mounting shoulder or of the filter at the mounting shoulder, caused by securing the filter to the shoulder, are confined to the shoulder structure, and do not detract from the desired precision flatness of the fitter and rim structure.

Inventor: PAYNE DAVID A
IPC: A01B63/22
Filed: 1993-12-23
Abstract: An implement depth control system includes a rotating link pivotally connected to the frame adjacent the depth control cylinder.  A cylinder pin contacts and rotates the link when the implement is lowered toward the field operating position.  One end of an adjustable length member is threaded through a turnbuckle mounted on the link and contacts an actuator to limit cylinder retraction and set operating depth. The opposite end of the member extends to an easily accessed location on the implement and includes a crank handle for turning the member and thereby adjusting the length between the turnbuckle and actuator to vary the depth setting.  An indicator near the crank handle provides an accurate depth indication at any depth setting, and relative depth adjustments may be made quickly while the implement is in the lowered field working position.

Title: Carrier for decorative graphics and lettering
Inventor: DRESSLER DONALD R
IPC: C09J7/02
Filed: 1994-09-22
Abstract: The invention relates to a hot peel carrier for decorative graphics and lettering applied to a substrate wherein the carrier has a film having opposite surfaces and an adhesive having a peel strength which decreases with increasing temperature, the adhesive being on a surface of the plastic film.      The invention also provides a laminate for use in applying graphics to a substrate which incorporates the carrier, methods of using and methods of using the carrier and laminate disclosed herein. The various embodiments disclosed herein incorporating the aforementioned hot peel carrier have significant advantages stemming from the fact that immediate after a graphic is heat applied to a substrate, the adhesive of the carrier has substantially no adhesion to either the substrate or to the heated adhered graphic. As a result, the carrier may be immediately removed from the heat applied graphic and underlying substrate without the use of any external force in the form of pulling or stretching. As a result, the invention may be used to provide high production volume capabilities in heat applied graphic and lettering processes, in addition the invention is particularly applicable to the production of multi-component letters or graphics wherein more than one color is desired.

Filed: 1994-11-10
Abstract: The present invention relates to a method of terminating undesirable gas migration in a well through one or more passages such as channels and microannuli in the cement sheath holding the casing in the well bore.  The methods basically comprise forming one or more lateral openings through the casing  and  the  cement  sheath  into  a  substantially  gas impermeable formation penetrated by the well bore.   One or more  horizontal  fractures  are  created  in  the formation extending from the lateral openings, and a fluid which sets into a substantially gas impermeable solid is deposited in the openings and fractures.  The fluid is permitted to set into a substantially gas  impermeable  solid  in the  openings  and fractures whereby passages in the cement sheath are plugged and gas migration is terminated.

Patent CA-2138364-A1 (CA)
Inventor: NEUMUELLER KONRAD
IPC: A47C1/027
Filed: 1994-12-16
Abstract: A jerk arresting mechanism for use particularly to prevent adjustable chair back rests from jerking forwardly.   A shaft extends through a housing and has a nut assembled to it within the housing.  The nut has limited axial movement into a locking position and is normally held out of the locking position by a spring.  When the chair back moves forwards without a jerking motion the shaft moves axially and relative to the housing, rotation of the nut upon the shaft allowing for shaft movement with the nut held out of the locking position.  However should the back rest jerk forwardly the shaft moves faster thereby overcoming the spring bias to move the nut into the locking position.  In the locking position, circumferentially facing stop surfaces of the nut and the inside of the housing interengage to prevent nut rotation and thereby prevent further axial movement of the shaft in the jerking direction.  The stop surfaces may be provided upon confronting ends of the nut and of an inwards extension of a housing.  Alternatively, the nut extends within the extension and confronting circumferential surfaces of the extension and nut provide the stop surfaces.  Guide surfaces may be provided to guide the stop surfaces together by slight nut rotation.
