In the feeding of sheet material to a machine such as a tire building former a sheet is first placed on a table and one edge of the sheet is aligned with a first datum line, preferably by tilting the table and supplying floatation air under the sheet. The sheet is then picked up and moved transversely through a predetermined distance by a gripping device to align the edge with a second datum line ...

A printing apparatus is provided which utilizes rolling pressure contact for printing, and includes a plurality of sets of serially arranged character elements mounted for movement on the external surface of a printing drum. Movement of the sets to place a desired character into printing position is accomplished by controlling the speed of a motor driving a pulley connected by cable to a given cha...

In a material handling vehicle having an operator platform, a sideshift carriage mounted for lateral movement relative to the platform, a traverse carriage mounted for lateral movement relative to the sideshift carriage and forks mounted to the traverse carriage, an improved sideshift control system monitors the position of the sideshift carriage to define home positions for the sideshift carriage...

A method of reclaiming clear PET resin from bottles and other containers is disclosed. PET resin contaminated with a hot melt type polyethylene copolymer based glue is treated with a chlorinated solvent and optionally subjected to azeotropic drying.

A safety device for detecting troubles in an optical transmission fiber of a medical laser application to prevent accidents characterized by using either a laser light reflector from the exit end surface of the fiber or a secondary light. When trouble is detected, the safety device operates a mechanism for interrupting the coupling of a beam of laser light into the transmission fiber. The safety d...

An "Automatic Exit Delay" circuit of a burglar alarm is placed on Stand-By whenever a "first" door is opened and the burglar alarm automatically starts to work right after the "last" door is closed. At that moment of arming a "Quiet Quick Test" Network automatically tests the alarm for proper functioning and generates a short "beep" to indicate such as well as the armed state of the alarm system.

A fuel briquette is described in which improved combustion is achieved by producing the briquette in a shape which yields a very large external surface area. This is achieved inter alia by forming grooves and recesses in the outer face(s) of a block of material and by forming holes through the block which further improved the draught during combustion. When the briquette is formed by a wet process...
