Abstract: A shaker table (10) for testing and quality control of devices attached to the table is shown. The mounting table has pneumatic exciters attached (50) thereto. The exciters (50) are attached to the mounting table (20) with a mounting bolt (128) and spacers (132, 132') that comprise an insulating material to inhibit thermal transfer between the device and the exciters (50) and between the mounting table (20) and the exciters (50). The mounting table (20) provides uniform distribution of forces applied by the pneumatic exciters (50). The forces are evenly distributed in all directions from the impact of the exciters on the mounting table. The mounting table (20) is supported on a foundation (2) by adjustable supports (4). The exciters are supplied with pressurized air from a source (12) through an airline (14).

Abstract: A backpack includes a waistbelt system with a pocket formed by a pair of longitudinally extending spaced-apart flexible straps for receiving the hipbone of the user. The pocket is formed by a pair of longitudinally extending spaced-apart flexible strap. One of the longitudinally extending horizontal straps on either side of the waistbelt system is adjustable so that each separate side of the waistbelt system can be tilted to fit users having large hips or stomachs. A pair of hip cushions are provided on the waistbelt system, one on either side, which are connected to the remainder of the waistbelt system in a manner which allows relative movement between the hip cushion and the waistbelt assembly to reduce frictional forces upon the user. A shoulder width-adjustment system includes a spring bias member and an adjustment strap which allows a pair of shoulder strap support members to be adjusted to the desired shoulder width.

Abstract: A drying device for warming or drying boots, gloves, mittens, and other articles has a pair of flexible hoses attached to an air blower and manifold. The remaining end of each hose is inserted into a boot or glove to facilitate warming or drying the inside of the boot or glove when air is forced through the flexible hoses by the air blower and the duct assembly. The length of the each flexible hose is independently adjustable so that the invention can be used with a variety of boot and glove sizes. Optional nozzles at the ends of the flexible hoses direct the air being blown into the boots, gloves, mittens, or other articles toward specific areas of the boots, gloves, mittens, or other articles. A spring clip is positioned inside the flexible hoses to help direct the flexible hoses into the boots or gloves to be dried and to keep the boots, gloves, mittens, or other articles held together.

Abstract: The flexible insulated heater includes a heater mat surrounded by an insulation jacket. The heater mat is preferably made of two layers of fiberglass reinforced rubber sheets laminated together with resistive heater wires sandwiched between the laminated sheets. The heater mat is formed with a curvature and size to fit snugly around the peripheral surface of the pipe that is to be heated. A jacket of thermally insulative material, such as a polymer foam, is molded over the external surface of the heater mat. The insulated jacket holds the heat generated by the heater mat from escaping radially outward, and it protects against burns to persons who might touch the heater.

Abstract: In a wireless sound monitoring system, ambient sounds are monitored by a microphone and transmitted over a phase or frequency modulated transmitter to a receiver. A sound actuated switch responsive to ambient sounds louder than a predetermined level turns the transmitter on and causes a hidden tone to be generated. A delay circuit caused the hidden tone to be terminated before the transmitter is turned off when the sound level decreases. In the receiver, a mute circuit responds to the hidden tone to control the output of a loudspeaker, and thus, the hidden tone prevents a squelch tail from being heard. The monitoring unit also includes a pulse generator to cause the hidden tones to be generated at regular intervals, but with short pulse widths.

Abstract: A soft child carrier including a soft body member attached to a relatively rigid back portion. A pair of shoulder straps are attached to the carrier adjacent to upper and lower ends of the back portion, and a waist belt extends from opposing sides of the lower end of the back portion. The relatively stiff back portion facilitates the transferring of the weight of a child to the waist belt such that a substantial portion of the child's weight is transferred away from the shoulder straps to thereby relieve the amount of weight carried on the shoulders and upper back of a person supporting the carrier. A seat adjustment is also provided whereby an adjustment strap extending along the back portion may be pulled or released to cause a height for the seat portion of the carrier to be increased or decreased depending on the size of the child.

Abstract: An ergonomically designed computer mouse pad for use with a hand operated computer mouse includes an inclined work surface for supporting the computer mouse. The mouse pad is symmetric so that it can be used with either the right hand or the left hand. During operation, the computer mouse is positioned on the inclined surface and the user's hand is positioned with the palm of the hand on top of the computer mouse so that the user's hand is positioned at an angle relative to the table supporting the mouse pad. The angled position of the hand creates ergonomic benefits such as reducing the muscular and skeletal strain on the user's hand and wrist. In addition, two inclined side surfaces adjacent the inclined work surface ensure that the user's hand and wrist does not rest on an abrupt edge.

Abstract: Environmental screening of products is facilitated and enhanced by employing screening compartments to subject products to differing environmental and functional conditions to expose latent defects in the products such as conductor weaknesses and discontinuities, component defects, material defects, and fragility. Within each compartment, products can be simultaneously subjected to various temperature and vibrational conditions as well as to stresses such as electric power cycling, voltage changes, frequency variations, and other functional stimuli. The thermal, vibrational, and other environmental and functional conditions created in each compartment are independently controlled and monitored from those conditions in other compartments. Products are readily transported between screening compartments, which can be adjacent each other, in order to rapidly subject the products to differing screening conditions while minimizing time and energy waste.

Abstract: A line reel for dispensing string, construction line, or cord includes a cap that can be inserted into one end of a spool holding the material to be dispensed, a midsection that can be inserted into the other end of the spool, and a rotatable handle connected to the midsection on the opposite side from the spool. In one embodiment, the cap and midsection frictionally engage the inside of the spool and can be pulled out of the spool for re-use with another spool. In an alternate embodiment, a latch structure on the cap and midsection latches the cap to the midsection in the spool so they cannot be easily removed from the spool once assembled. The line reel includes a notch to hold the free end of the construction line or string. The cap, spool, and midsection, while positioned structurally so that they do not rotate in relation to each other, are able to rotate in relation to the handle to facilitate dispensing the construction line.

Abstract: A shingle is formed with a first, or trailing, side edge folded over toward the top surface of the shingle to catch moisture and direct it down to the top surface of the next lower shingle. A second, or leading, side edge of the shingle is not folded. An "S" shaped fold, spaced apart from the trailing edge fold, receives the unfolded leading edge of an adjacent shingle. The trailing edge and S fold form a gutter under the leading edge of the adjacent shingle. The top edge of the shingle is folded-over toward the top surface of the shingle for engagement with the folded-under lower edge of the next higher shingle. The folded-over top edge extends to the right or leading edge of the shingle and slides under the left edge of the folded-over top edge of the next adjacent shingle to the fight side. The folded-under lower edge extends along the lower edge of the shingle but leaves a gap relative to the folded-under lower edge of the lateral adjacent shingle.
