Integrally molded glides are formed on the inner faces of the side wall segments. The drawers have glide flanges mounted on the sides cooperable with the molded glides slidably mounting the drawers on the glides. Stops are formed an the drawer glides and drawers to retain the drawers in a closed position within the cart and to prevent the drawers from being inadvertently pulled from the cart. Castors are mounted to the bottom of the in-shaped frames at bottom portions thereof to support the cart on wheels. The cart can have a central vertical spine and double-faced walls mounted to the vertical spine to form a vertical partition in the cart for mounting two rows of drawers in side-by-side relationship.

Title: Method and apparatus for checking film-cutting positions
Inventor: FLECKENSTEIN ALLEN E
IPC: G03D15/04
Filed: 1990-12-13
Granted: 2000-08-01
Abstract: A method and apparatus for determining whether a predetermined cut position lies within an unexposed portion of a roll of film is provided. A first density sensor 20 senses film density of a roll of film (10) and produces film density data. The film density data is stored in a first data storage device (50). A second data storage device (52) reads and stores a film density data value indicative of the lowest value of the film density stored in the first data storage device (50) and outputs this as base density data. A second density sensor (22) senses the film density at a predetermined cut position and produces cut position density data. A counter (66) counts pulses produced by a film drive and, when a predetermined number of pulses has been counted, indicating the arrival of the film at the predetermined cut position, the counter (66) produces a control signal that causes a comparator (26) to compare the base density data to the cut position density data. The comparator (26) produces a cutter control signal that causes a film cutter to cut the film (10) at the predetermined cut position only when the value of the cut position density data indicates that the film density at the cut position is within a predetermined range of the base density. In a typical installation, the film is comprised of several rolls of film spliced together. The invention includes a first splice detector (54) that detects a splice at a first time and a second splice detector (56) that detects the splice at a second subsequent time to identify each roll of film. The base density information is then keyed to a particular roll of film.

Inventor: ORLOWSKI DAVID C
IPC: F16J15/447
Filed: 1991-01-25
Granted: 1994-06-28
Abstract: ABSTRACT OF THE INVENTION    An isolator mechanism is provided for use with a machinery housing and a rotatable shaft protruding through the housing.  The isolator mechanism comprises a stator ring affixed to the housing and a rotor ring which is attached to the shaft and which nests within the stator.  The stator and rotor are so shaped that the stator has a male cylindrical surface, and the rotor has a female cylindrical surface located radially outwardly of the stator male surface.  A solid, deformable annular seal member is mounted on the rotor female surface and engages the stator male surface when the rotor and seal member are at rest.

Title: Radio with message reception indicator
Inventor: GROTHAUSE TIMOTHY A
IPC: H04W88/02
Filed: 1990-02-26
Granted: 1994-04-19
Abstract: A radio (10) measures and stores (16, 18) the ambient sound (or noise) level of its environment. When a message is received, the current noise (or sound) level is compared to a threshold (56). If the ambient noise level is such that an audible tone may not be heard by the radio user, a silent alert is automatically activated (62) regardless of whether the silent enunciator has been previously selected (enabled) by the radio user. In another aspect of the present invention, if the ambient noise level is such that an audible tone may be inappropriate (i.e., library, courtroom, or certain hospital areas), the silent alert is also automatically activated regardless of whether the silent enunciator is enabled so as not to disturb others.

Filed: 1992-08-04
Granted: 1997-12-30
Abstract: A key-in-lever type door lock which can be installed on either a left hand or right hand door by a left-right reverse operation of a reverse plate. The lock comprises a lock assembly which regulates a uni-directional, 45-degree rotation of a handle thereof and a latch assembly which converts the 45-degree rotational movement to a retraction of a latch bolt.
