Abstract: A mechanical strain isolator mount 10 is provided to preserve the alignmental integrity of alignment sensitive instrument 25. Alignment sensitive instrument 25 is mounted on rectangular base 11. Flexural legs 15, 16, and 17 are connected at their proximal ends to rectangular base 11 at points, A, B, C, respectively. Flexural legs 15, 16, and 17 are also spaced parallel to sides AB, BC, and CD respectively. Mounting pads 20, 21, and 22 are respectively connected to legs 15, 16, and 17 at the distal ends thereof and attach mechanical strain isolator mount 10 to substrate 30 by means of threaded bolts 23. When a mounting pad and its respective leg is subjected to lateral strains in either the X or Y directon via substrate 30, the respective leg relieves the strain by bending in the direction of the strain. An axial strain on a mounting pad in the Z direction is relieved by a rotational motion of legs 15, 16, and 17 in the direction of the strain.

Abstract: The elevator car is disposed in a frame which moves on rails through the elevator hoistway. A pendulum mount is used to mount the car in the frame so that the car is free to swing within the frame in pendulum fashion. Both lateral and torsional swinging movement of the car within the frame are controlled. A combination spring/damper assembly interconnects the car and the frame to control such lateral movements of the car whereby the car is softly stabilized within the frame.

Abstract: An electric in-tank fuel pump for vehicles which is provided with a noise-reduction jacket of relative soft material spaced from the pump housing by internal projections on the jacket which contact the pump housing. An extended skirt on one embodiment serves to collect vapor which rises in the jacket to maintain a low liquid fuel level around the pump. A quick connect-disconnect from the pump to a fuel line with an integral unidirectional valve is provided to maintain fuel line pressure when the pump is not operating. Also, an inlet unidirectional valve is provided to prevent fuel from siphoning out of the pump.

Abstract: A support of an intank pump at a pump support, which includes webs of elastic material that extend from the pump to the pump support in a direction deviating at an angle .alpha. from the radial which is determined by the longitudinal axis of the fuel pump. During swelling of the webs by the fuel, a rotary movement is thereby imparted to the pump without influencing the suction height. The webs may thereby have a relatively large volume as a result of which a good damping is achieved.

Abstract: A dynamoelectric machine mounting assembly is provided with a plurality of adaptors positioned at spaced locations adjacent to the perimeter of a generally cylindrical frame of a dynamoelectric machine having a central axis. At least one end of each of the adaptors is attached to the frame and a band encircles the frame and the adaptors and exerts a radially inward force on the adaptors. Means are provided for connecting the band to an external structure. By mounting the adaptors on the frame such that one end of each adaptor is radially spaced from the frame, a tapered gap is formed between that end of the adaptor and the frame such that when the adaptor is subjected to a radially inward force from the band, the central portion of the adaptor can deform radially inward without contacting the periphery of the machine frame.

Abstract: A humidifier pad for use in humidifiers suitable for adding moisture to the air circulated by a forced air furnace is described together with its method of manufacture. A slab of open-cell foam is stamped using a reciprocating cutter to form humidifier pads which are seamless. These seamless pads are adapted to be fitted onto the cylindrical support frame of the humidifier and the pad is especially useful in a combination with a type of frame which is collapsible cylindrical and which facilitates removal and replacement of the pad.

Abstract: This invention provides a support for a tubular humidifier pad such that the pad can be replaced easily and efficiently. This is achieved by providing a support having a movable end which can be collapsed to release the pad which is carried on axial stringers attached to this end. The stingers deflect radially inwards so that the old pad can be removed over the collapsed end and a new one put in place. The procedure is then reversed to hold the pad on the support.

The lamp supporting device includes an elongated, horizontally extending support member and a frame. The support member is positioned through the center of the frame so that the frame is spaced from the support member and surrounds the midportion of the support member. Eight springs interconnect the frame and the support member. The lamps are mounted on the support member and spaced from the frame. The top end of a pole is connected to the frame. The frame extends upwardly from the pole top end. The bottom end of the pole is joined to the mobile unit. The springs act to absorb any shocks transmitted to the shock absorbing device as the portable lighting unit is moved.

Abstract: Motor mounting system is designed so that the torsional mode resonant or natural frequency is less than twice the frequency of the motor power supply divided by the square root of two (.sqroot.2). The illustrated mounting arrangements are "soft" with respect to torsional mode vibrations, and yet are "stiff" with respect to axial and tilting mode vibrations. In one arrangement, lugs are formed preferably from a tough and strong sheet or strip material that is thicker and substantially stronger and stiffer (even in the radial vibration mode) than would usually be desirable from a torsional vibration isolation standpoint, but means are provided for promoting flexure in the vicinity of the parts of the lugs that will be subject to the most flexure or deflection. These flexure promoting means may be in the form of tuning apertures formed along a preselected, longitudinally extending neutral axis of each lug so that the strength of the lug will not be objectionably compromised for axial loading conditionss.

Abstract: A vibration isolating motor mount has a U-shaped mount having the end of the legs of the "U" arranged at right angles thereto to form mounting ears. One leg end ear is arranged to be connected to a motor support plate which is perpendicular to the plane of the legs of the U-shaped mount. The plate is, in turn, attached to a first end of the motor with the plane of the plate being perpendicular to the axis of rotation of the motor. The end ear of the other leg is arranged to be connected to a motor support frame having the plane of the frame also perpendicular to the axis of rotation of the motor. The other end ear may include a vibration absorbing bushing isolating the respective mounting ear while surrounding a mounting pin attached to the support frame. The plane of the legs of the U-shaped mount is arranged to be co-planar with the axis of rotation of the motor. A plurality of the motor mount may be equally spaced on the periphery of the motor support place to provide added support for the motor.

Abstract: A proof mass for an accelerometer is electromagnetically constrained in three orthogonal directions. An array of filaments forms an elastic suspension for the proof mass to constrain it in the remaining degrees of freedom. The resulting instrument has the potential for low cost and high-accuracy operation over a wide temperature range without the use of temperature controls. An improved transition device provides a relatively simple, controllable and inexpensive means for temperature stabilizing the elastic suspension.

Abstract: A flexure mounted gimbal support assembly for limited angular rotation hag a flexure assembly of an open web construction mounted between a platform and a gimbal assembly via a ball bearing assembly. The flexure assembly has a plurality of flexure elements having a high flexibility so that the flexure assembly provides less resistance to rotational motion than the static ball-bearing friction over the limited angular rotation. A slip-ring assembly is mounted inboard of the flexure assembly to provide direct connection to angle measuring resolvers and direct-drive dc torque motors, which eliminates slip-ring brush-on-ring effects and torque motor brush friction effects.

Abstract: An assembly includes a band which is adapted to encircle and tightly clamp motor housings of different sizes, and mounting arms located on the band extend radially outwardly. The arms are adapted for connection to a mounting surface and provide isolation of torsional motor vibrations. Each arm includes a slot to receive the band, and an end clamped between the band and motor housing. The band has openings that receive and locate tabs on the arm ends. A band extension enables enlargement of the band to accommodate a larger motor. The band openings are arranged in sets to permit predetermined angular spacing of the arms for different band circumferences. Thus, depending on the dimensions of the arms, a single band and arm kit may be used to mount motors of two different diameters in a given blower installation with proper angular alignment of the mounting arms and blower housing bolt holes.

Abstract: A flexible vibration dampening mounting assembly for supporting an electric motor within a blower housing. The flexible mounting is normally provided as part of the electric motor and consists of a plurality of circumferentially spaced hardened steel mounting arms which are joined to the motor main frame by a hinge connection which permits attachment of the hardened steel mounting arms to the hinge pins previously welded to the main frame and thus eliminates the possibility of embrittlement of the mounting arms due to heat generated during welding operations.

Abstract: A mounting system for an electric motor or the like utilizing three, one piece motor mounting brackets made of formed wire and secured to the motor at intervals therearound. The outer ends of the brackets are adapted to be bolted to a support, and the inner ends of the brackets may either be snapped into place on the motor or welded or otherwise rigidly attached to the motor. In certain embodiments of the mounting system, the brackets may be rotated relative to the motor so as to be folded adjacent to the motor for compact packaging of the motor for shipping and may be extended for mounting the motor on the support, and in other embodiments, the brackets may be shipped separately from the motor and then readily installed on the motor prior to installation of the motor.

Abstract: Motor vibration isolating arrangements and systems using such arrangements are disclosed. In preferred arrangements, leaf spring mounting arms have low torsional spring constants and yet strength to withstand shipping and handling loads. The mounting member spring constants for axial, radial and tilting vibration modes are selected in specific forms so that the characteristic vibration transmissibility ratios for these modes are each close to unity, but so that torsional mode vibration transmissibility is substantially less than unity. In particularly preferred arrangements, sheet steel having a martensitic grain structure is utilized. In some forms, the motor shell constitutes one weldable member and a holding plate is weldable. The spring material is protected by heat sinking from being softening and weakened by conventional welding processes. The heat sinking members also contribute to a very strong fastening scheme.
