Patent CA-2099094-A1 (CA)
Title: Adjustable rack for electrostatic painting and the like
Inventor: NAGEL THOMAS O
IPC: B05B13/02
Filed: 1993-06-23
Abstract: ABSTRACT OF THE DISCLOSURE       A  rack,   for  supporting  workpieces  during  an electrostatic paint spray operation, is comprised of a rack frame arranged to be suspended from a conveyor system and having  means  for  selective  mounting  and  removal  of individual  cross  bars.     Stainless  steel  hooks  are permanently welded to the cross bars and provide means for supporting of the workpieces.  When the cross bars become heavily layered with coating material, they may be removed from  he frame and burned off in a high temperature oven without deterioration of the hooks or loss of electrical conductivity.      Necessary   burn-off   operations   are facilitated by easy removability of the cross bar elements, which enable the cross bars to be burned off separately from the rack frames, which need to be burned off less frequently.  This also permits the oven to be loaded more compactly  and  with  less  tangling  of parts.    Highly efficient  electrical   contact  is  assured  by  using permanently  welded  stainless  steel  elements  for  the workpiece-supporting hooks, and by using a stainless steel hook  element  for  supporting  the  rack  on  the  system conveyor.

Inventor: KUNREUTHER STEVEN
IPC: B65D85/24
Filed: 1993-10-21
Abstract: ABSTRACT       STEVEN KUNREUTHER                  IMPROVED CLIP OF ATTACHMENTS     one  or both ends  of  the connector bar  is  extended outwardly  beyond  the  main  section  of  the  bar  to which  the attachments are mounted. The extended end provides access to the clip from the exterior of the attacher housing, permitting the clip to be manually advanced if the feed mechanism fails. An element may be situated on one extended end to facilitate grasping. In a clip having two connector bars, the ends of both bars extend in the same direction.  The extended ends may be bent towards each other and may be connected to form a bridge.   A second aspect of the invention relates to a connector bar which has an element designed to cooperate with the housing to prevent advancement of the clip all the way through the housing channel, thereby requiring the operator to remove the empty connector bar from the device for better control of disposal.

Title: Apparatus and Methods for Making a Portion of a First Name Space Available as a Portion of a Second Name Space
Inventor: WINTERBOTTOM PHILIP S
IPC: G06F15/16
Filed: 1993-11-29
Abstract: Apparatus and methods for incorporating a portion (including all) of a first name space into a second name space. An agent operating in the first name space receives first operation specifiers which use names as they are used in the second name space from an entity operating in the first name space and translates the first operation specifiers into second operation specifiers which specify the same operations and use the names as they are used in the first name space. The apparatus and methods are implemented in the Plan 9 operating system. The first and second name spaces areorganized as trees and belong to a first process operating on a first processor and a second process operating on a second processor. The first operation specifiers are Plan 9 file protocols which the first process receives from the second process. The second operation specifiers are Plan 9 file system calls made by the first process. The translation between the file protocols and the system calls is made using a data structure which permits the names in the portion as they are used in the second name space to be mapped onto the names as they are used in the first name space.

Title: Toothbrush with toothpaste dispensing system
Inventor: NINPONG ROMSON
IPC: A46B11/00
Filed: 1993-12-07
Abstract: A toothbrush is provided having a hollow handle forming a toothpaste receiving reservoir.  A head having bristles for brushing the teeth of a user extends from the handle and has an internal passageway for transporting toothpaste between the reservoir and the bristles.   A flexible one-way valve formed by two opposed, abutting thin walled flaps is located at the bristle end of the internal  passageway  for  controlling  dispensing  of toothpaste onto the bristles.
