Abstract: A laser scanning system for scanning a laser beam across  a material,   comprises  a laser  source for generating a laser beam travelling along a first optical path and a beam reflector in the path of the laser beam.       The beam reflector is rotatable about a rotation axis and includes a single mirror facet which extends in a plane oriented at an angle of 45° relative to the rotation axis and has a center of rotation lying on the rotation axis, for reflecting the laser beam into a scanning beam travel-ling along a second optical path orthogonal to the first optical  path  and  moving  at  a  substantially  constant angular velocity.  A scan lens is disposed in the path of the scanning beam for focusing the scanning beam onto the material  and  providing  a  focused  beam  spot  moving repeatedly in a linear direction across the material.  The laser scanning system of the invention further includes a support for supporting the laser source,  beam reflector and scan lens relative to one another.  The support has a unitary body formed with a first bore extending through the body so as to define first and second opposed openings for receiving the laser source and the beam reflector, respectively,  and enabling same to be mounted to the body such that  the laser  beam is  aligned with the rotation axis. A second bore extends at least partially through the body and intersects the first bore orthogonally so as to define a third opening for receiving the scan lens and enabling same to b? mounted to the body such that the center of rotation of the mirror facet is aligned with a center point of the  scan lens.   Such a  laser scanning system is particularly useful in laser imaging.

Title: Device for lodging a suspending strap for a portable object
Inventor: SHIMURA NOBUYOSHI
IPC: A45F3/02
Filed: 1990-11-20
Abstract: Disclosed is a suspending strap lodging device which allows a suspending strap to be extracted from a portable object, such as a bag, or withdrawn into it in accordance with whether the strap is needed or not.  The device comprises:  a withdrawing mechanism for allowing the strap to be extracted or withdrawn a desired length; a locking mechanism for controlling movements of the strap steplessly in both the lodging and the extracting directions; and a releasing mechanism for cancelling the locking effected by the locking mechanism.  The locking mechanism provided in the withdrawing mechanism prevents the weight of the portable object or the impact load caused when the object is lifted from being directly exerted on the strap, thereby enabling the strap to be securely locked in position and allowing it to enjoy a long service life.  Also disclosed is a strap equipped with a strap lodging device.  Since it is equipped with a lodging device of its own, this strap can easily replace the straps of existing portable objects.          Further, disclosed is a mounting structure for allowing a strap lodging device to be mounted on a portable object.          The structure, which can be applied, for example, to a video camera, adopts a single strap which serves as a shoulder strap, a grip strap, and a hand grip.

Title: Direct vent oil furnace
Inventor: O'HEARN LANCE R
IPC: F24H3/02
Filed: 1991-04-12
Abstract: DIRECT VENT OIL FURNACE     ABSTRACT        An improvement in  oil-fired, forced air furnace, or hydronic heating system or  domestic water heating vented appliances, where gaseous products of combustion are ducted through a stainless steel flue pipe to the outside and the waste heat of which, acts to heat incoming combustion air. The improvement involves the combining of an outside air intake/exhaust manifold, a means of ducting the incoming fresh air to the burner, in coaxial vent material, and an air/flue gas separation system.  The products of combustion are thus sealed from the home environment, and driven to the exhaust terminal by the static pressure generated by the oil burner, while exchanging heat normally wasted in a chimney to the incoming combustion air.

Title: Countertop can crusher
Inventor: BENSON JOHN D
IPC: B30B9/32
Filed: 1991-11-15
Abstract: An apparatus for crushing workpieces includes a drive mechanism having a gear reduction train and a moveable rack member which is centered above a compression plate for even, linear force transmission. Force is transmitted to the rack member on two opposite sides thereof by a pair of pinions which engage apposite rows of rack teeth. The compression plate is integral with a pair of opposite guide sleeves, which are mounted for sliding movement with respect to vertically extending guideposts.      A'crimper mechanism is mounted to the compression plate for crimping the workpiece prior to compression. The combination of the improved drive train, which prevents jamming of the apparatus due to uneven force transmission, and the crimper mechanism allows a relatively small motor to be used in the unit, which increases its portability, economy and affordability. An additional aspect of the invention involves an overload sensor arrangement, which causes the apparatus to reverse in mid-stroke if too much compressive force is being generated between the compression plate and the workpiece. A door interlock switch arrangement makes the apparatus safer for use by children or other persons.
