Title: Reciprocating floor conveyor for conveying palletized loads or the like
Inventor: FOSTER RANDALL MARK
IPC: B65G17/06
Filed: 1995-10-23
Granted: 2002-02-26
Abstract: A reciprocating floor conveyor (10)  including a support frame (12), and a conveyor floor (14), which is comprised of a plurality of laterally spaced-apart conveyor slats (16), a plurality of laterally spaced-apart holding slats (18), and a series of divider planks (20).  Divider planks (20) are fixedly secured to  the upper portion of  support  framework  (12). Conveyor slats  (16)  are mounted on support frame  (12)  for longitudinal  reciprocation between  "start"  and  "advanced" positions.  Holding slats (18) are mounted on support frame (12) for vertical movement between and "up" position in which the holding slats (18) are above the conveyor slats (16), and a "down" position, in which the holding slats (18) are below the conveyor slats (16).  The load is conveyed by lowering the holding slats  (18),  advancing the conveyor slats  (16),  to convey the load, raising the holding slats and retracting the conveyor slats to their "start" position, and repeating the process.

Abstract: A switched electrical device adapted to be coupled to a complementary locking type electrical connector by initial relative axial movement therebetween and subsequent relative rotational movement therebetween, The switched electrical device includes a housing with an inlet opening for receiving the complementary electrical connector, a rotatable locking type electrical connector with a set of electrical contacts for engaging the electrical contacts of the complementary electrical connector, a switch mounted within the housing for selectively supplying electrical energy to the set of electrical contacts of the electrical connector, an operating handle for moving the switch between "on" and "off" positions, and an interlock mechanism for releasably locking the switch. The interlock mechanism selectively locks the switch in its "on" position so that it cannot move to its "off" position, until after the complementary electrical connector has been inserted into said opening and rotated to a locked position. The interlock mechanism also prevents removal of the complementary electrical connector from the inlet opening until the operating handle has been moved to its "off" position, which disconnects power to the electrical contacts of the switch connector and the electrical contacts of the complementary connector.

Abstract: A filter mask has an eye shield comprising a sheet of flexible transparent material sealed to the mask along its lower edge. That edge of the eye shield material has one or more widthwise folds so that, while the upper edge of the mask can follow the contours over the nose and along the cheeks of a user the eye shield can adopt a more gentle curvature by relative compression of the folds where they pass over the nose and relative opening of the folds to each side. A comfortable fit can thereby be achieved without creasing of the eye shield and without detriment to the sealing of the mask against the user's face and the sealing of the eye shield to the mask.

Abstract: La présente invention se rapporte à un système de fondations avec assise en matériau composite à profil bas ainsi qu'aux procédés de fabrication et de montage. Ledit système utilise des modules à ressorts (16) fabriqués en matériaux composites moulés qui sont soutenus par des éléments d'ossature intérieure (22). Le profil bas des modules à ressorts ainsi que l'élasticité du matériau composite permet à celui-ci de reprendre son état non comprimé à partir d'un fléchissement de profondeur totale sans déformation rémanente; cette caractéristique permet de diminuer considérablement la hauteur de l'assise de la fondation (10), dans laquelle les modules à ressorts sont directement fixés aux éléments (18, 20, 21) de l'ossature de la fondation. La petite taille ainsi que la géométrie simple des modules à ressorts convient particulièrement à un agencement flexible et à un montage automatisé de fondations à profil bas.

Abstract: This invention enables the key telephone system to send a busy tone to a party calling on a main extension number when a telephone call to the main extension number is received when a pseudo extension number is in use.    The receiving mode is memorized in the memory of the main unit.  When a telephone call to the main extension number is received when the pseudo extension number is in use, a busy tone can be sent to the calling party on the main extension number.    According to this invention, the calling party thus knows that the key telephone set, which is the destination of his call, is busy.

Abstract: The present invention provides a method of reducing tin defects in flat glass made by the float process. In the float process, molten glass is delivered onto a pool of molten tin within an enclosed chamber and formed into a glass ribbon. Oxygen gas dissolved in the molten tin combines with the tin to form tin oxide which vaporizes and collects within the chamber, resultingin defects in the glass. In the present invention, hydrogen gas is introduced directly into the molten tin to react with the oxygen gas and tin oxide within the molten tin to form water and elemental tin, resulting in a reduction in the amount of tin oxide within the molten tin. In one particular embodiment of the invention, the hydrogen gas is introduced into the molten tin through an elongated, porous graphite member submerged in the molten tin within the forming chamber such that it extends along and is located outboard of selected portions of the edge of the glass ribbon.

Abstract: The air regulator for vehicles of the present invention is provided with, within a casing, an evaporator which cools air, a heater which reheats the air cooled by the evaporator, and an air mix damper which is disposed on the downstream side of the evaporator and on the upstream side of the heater and in close proximity thereto, and which regulates the amount of air passing through the heater; a heat reflecting surface is formed on the heater side of the air mix damper.  By means of this, it is possible to prevent the thermal deformation of the air mix damper by reflecting the radiation from the heater side using the heat reflecting surface.  Accordingly, the sliding problems of the air mix damper can be prevented.

Abstract: A construction vehicle attachment in the form of a pulverizer-ripper unit that includes a pair of jaws confronting and closing on one another and an independent ripper-shank that has a replaceable ripper-tooth. Each jaw includes teeth that serve to engage and fracture concrete slabs. The pulverizer-ripper unit operates under power of any one or a combination of hydraulic, pneumatic, electric, or mechanical powers. The teeth on each jaw are alternated at differing lengths and sizes. The ripper-shank is an elongated finger-like projection pivotably mounted on one of the jaws. The ripper-shank is significantly longer than either jaw and has a range of arcuate motion from a parked-position to a fully-deployed-position with at least two intermediate positions therebetween. The ripper-shank can be locked into such an intermediate position and allows an operator to initially rip up or pry up surfaces, sort and properly orient large chunks, and then subsequently pulverize the chunks with the jaws.
