Title: Refuse separator
Inventor: ARMSTRONG ERNEST T
IPC: B07B13/00
Filed: 1991-02-13
Abstract: Abstract A trash separator that sorts bottles and cans from other, non-recyclable refuse.  This separator consists of a slide 4 with an inlet 1 for all refuse at the top and an outlet 3 for the refuse at the bottom.  The refuse is separated because the size and weight of the bottles and the cans is such that they attain a higher velocity sliding down the slide than the other refuse.  These faster moving bottles and cans are sent on a trajectory that lands them in a far receptacle 7 while the remainder of the refuse, which is slower moving, falls into the receptacle 8 that is closest to the terminal end of the slide. The apparatus is a molded plastic cover that sits atop the receptacles and can easily fit in the kitchen, garage, office or on a street comer.  It is designed to make recycling more convenient, sanitary and enjoyable.

Title: Battery state of charge indicator
Inventor: LAMBERT JOE C
IPC: G01R31/36
Filed: 1991-05-09
Abstract: A method for measuring and storing the state of charge of batteries, such as used in electric vehicles. The stored charge value is initially derived from the value of battery terminal voltage measured prior to connection of the battery to the load, eg. the traction motor. While the battery is connected to the load, approximated state of charge values are periodically derived by adding a correction voltage, comprising the product of measured load current and of a predetermined value of internal resistance, to the measured terminal voltage of the battery. The stored and approximated state of charge values are periodically compared and the stored state of charge value is decremented by a predetermined increment in response to the stored charge value having exceeded the approximated state of charge value during each of a predetermined plurality of consecutive comparisons.

Title: Laminar segments for use with comminution equipment
Inventor: HARRIS TERRANCE R
IPC: B02C17/22
Filed: 1990-01-03
Abstract: A novel laminar assembly (10) for use with comminution equipment, such as a liner for protecting the shell of an ore crushing mill or as a wear tip on a blow bar for use in a rock impact crusher.  The laminar segment includes a plurality of laminae (10) which are attached to each other with a rod (22) extending through holes (18) positioned in the base of the laminae (10), thereby forming a segment of virtually any desired length. Mounting bolts (14) are configured in two pieces, with an axial hole (20) extending through the head of the mounting bolt (14) by which they are mounted to the rod (22) and thereby attached to the liner segment. A  second piece (42) of the mounting bolt threadably engages the head of the bolt and extends through the mounting surface of the comminution equipment being used. The utilization of small laminae (10) enables the laminae (10) to be cast and heat treated such that the microstructure throughout the laminae (10) may be strictly controlled, thereby providing a laminae (10) with consistent hardness and toughness throughout the laminae (10).
