Abstract: Pivotable Power Feed Connector Abstract A pivotable power feed connector (100) is disclosed which includes a pivotal connector (116) adapted to be connected to a flexible conduit or cable (118) having a series of conductors (120) extending therethrough.  The pivotal connector (116) is pivotably connected to a pivot block assembly (132) through which the conductors (120) extend.  The pivot block assembly (132) is, in turn, connectable to a contact block (200) with the conductors (120) conductively connected to a set of prong terminals (212) extending outwardly from the contact block (200).  A protective cover (228) is securable over the contact block (200) so as to prevent the prong terminals (212) from being exposed during assembly and disassembly.  The cover (228) automatically exposes the prong terminals (212) as the power feed connector (100) is moved into engagement with an electrical receptacle (102) in a modular office panel (104).  The pivotal connector (116) allows the conduit or cable (118) to be swiveled through an arc of approximately 180° to any desired position.  The pivotal connector (116) is also manually removable from interconnection with the pivot block assembly (132).  Such removal allows the conduit or cable (118) to be pulled back from the conductors (120) and cut to a desired length.  The power feed connector (100@ also includes a power feed cover (248) which can be utilized in part to maintain the pivotal connector (116) in either of two spatial configurations relative to the pivot block assembly (132).

Granted: 1994-07-26
Abstract: ABSTRACT OF THE DISCLOSURE         Existing devices for stabilizing a safety helmet such as a hard hat are either unduly complicated or ill adapted as retrofits for existing helmets.  A simple restraining device for use on new or existing helmets includes a bracket located at the centre of the interior of each side of the helmet for pivotally supporting front and rear headbands.  Pins extending through the headbands into arcuate slots in the brackets limit rotation of the front and rear headbands with respect to the brackets.  A force tending to lift or rotate the helmet from the wearer's head will cause the headbands to pivot downwardly and inwardly against the wearer's head, thus inhibiting removal thereof from the head of the wearer.

Abstract: INDUCED DRAFT WARM AIR FURNACE  WITH RADIANT INFRARED BURNER                    ABSTRACT OF THE DISCLOSURE            An induced draft warm air furnace employing a radiant infrared burner.  The use of a radiant burner results in a very low concentration of oxides of nitrogen (NOx), in the combustion gases produced.  In addition, the use of a radiant burner eliminates the combustion roar produced by other types of burners found in similar furnaces. Further, the invention allows the attainment of the advantages of a radiant burner in a furnace of otherwise standard design with only minor modification.  The scope of the invention includes the use of the radiant burner within a combustion chamber which is either within the heat exchanger enclosure and joined to the heat exchanger or within a burner box mounted external to the heat exchanger enclosure but having means for the free passage of combustion gases from the combustion chamber to the heat exchanger.  The use of induced draft eliminates the possibility of combustion gases leaking out of the combustion chamber or heat exchanger.

Inventor: KOBAYASHI HIRONOBU
IPC: F23D1/02
Filed: 1991-03-07
Granted: 1995-06-27
Abstract: The present invention is directed to a burner for pulverized coal.  The burner has a coal duct for pulverized coal and primary combustion air and a secondary combustion air duct such that the coal, primary air and secondary air mix outside the outlet nozzles of the duct in a mixing zone where combustion occurs.  Coal distribution means in the coal duct create, adjacent the outlet nozzle, at least one outer zone of flow spaced from the coal duct axis and at least one inner zone of flow nearer the coal duct axis.  These are means for decreasing flow in the outer zone relative to the flow in the inner zone, prior to entering the mixing zone.  To achieve good mixing, and promote NOx reduction, the coal concentration in the outer zone is higher than in the inner zone.

Abstract: A method of gray scale printing of dots of one or more colors into pixels and in a controlled ordered sequence into a plurality of super pixels defined by a given number of said pixels, characterized in that:  one or more levels of dot loading (Pg. 29 line 20 et seq.) are used to achieve different values of gray level in a multiple-level gray table.  This generic  method  is  applicable  to  both  ink  jet  and electrophotographic printing species of this invention.         In one electrophotographic printing species of this invention, there is disclosed a method of electrophotographic color printing which includes mixing a plurality of colors in a single plane and in dot-next-to-dot (DND) pixels within a plurality of super pixels to produce a color image, whereby the sum or the multi-color dots printed in any super pixel is limited to the number of subdivided individual pixels therein (Pg 28 line 19 et seq.), thereby assuring dot-next-to-dot (DND) always printing of said colors in a single plane.  The above method further includes varying the area of each printed color dot within each pixel of a super pixel in order to control the gray scale of a printed color image.         Gray scale printing is achieved by controlling the selection of a gray table entry level number (Pg. 29 line 20 et seq.)  representative of one of several available entry level numbers corresponding to a plurality of different dot loadings for a corresponding plurality of differently printed super pixels.
