This invention deals with a motorized device which allows independent movement into and out of a pool of water, which device may or may not be under the control of the invalid or handicapped person. The device comprises a motorized pair of arms which carry a bar, which bar has mounted on it, a carrier for a person. The device, in spite of a high movement of the bar overhead, allows for the transportation of the person through essentially a horizontal plane.

An independent suspension for use in a front wheel or a rear wheel of an automobile is provided. It produces a varied characteristic of camber variation for a fixed roll center height and a fixed scuff variation and, consequently, improves freedom of suspension design and offers enhanced operational stability. An upper arm is divided into a knucle side upper arm and a vehicle side upper arm, the two upper arms are interconnected so as to be shakeable in the direction of vertical movement of the ...

A suspension system for a motor vehicle in which at least two wheels are independently suspended from the frame of the vehicle with at least one control arm and wherein motors are selectively actuated by sensors in the driver's seat to move the control arm on each side in response to inertial and centrifugal forces acting on the driver during operation to counteract the adverse effects of such forces.

An independent landing monitoring system (ILM) for guiding airborne vehicles on final approach to a landing using a ground-based beacon which transmits a sequence of pulse signals including an omnidirectional signal coded to identify its location and used for initial approach, followed by time spaced directionally radiated right/left and up/down signals used for precision guidance along the final approach path. The time spacing of the various beacon signals and their order of succession in the s...

The drawings illustrate a rear suspension system for a motor vehicle, including a laterally extending member connected by vertically oriented pivotal means to a wheel carrier. A torsion bar is formed to include a transversely oriented center portion connected to the frame, and longitudinally oriented end portions connected at the distal ends thereof to the wheel carriers rearward of the pivotal connection between the wheel carrier, and the laterally extending member such that the distal ends of ...

A series-type independent inverter comprising a bridge network that includes silicon controlled rectifiers, the bridge network having an a.c. diagonal provided with a circuit comprised of LC-elements, and having a d.c. diagonal provided with a coupling capacitor, and also comprising at least one uncontrolled semiconductor rectifier adapted to limit the voltage across the silicon controlled rectifiers. The inverter includes a saturated ferromagnetic element with a polarized magnetic circuit and w...

The present invention relates to a suspension for a set of wheels of a vehicle, in which the wheels are rotatably carried by the end of an axle arm of which the hub is mounted to rotate at the end of a cross member fast with the structure of the vehicle. According to the invention, the suspension is constituted by two torsion bars coupled for each of them between one of the arms and an element fast with the structure. Each torsion bar extends parallel to the axis of the hub and to the exterior t...

The drawings illustrate an independent rear suspension system comprising a transversely-oriented control arm pivotally connected at the inner end thereof to the rear cross member of the vehicle frame and extending outwardly past the side rail, with a wheel spindle formed on the outer end thereof. A shock absorber is mounted between the control arm and the frame side rail, and a longitudinally-oriented cantilever leaf spring is secured at the rear end portion thereof to the control arm and at the...

In a miniature record player for reproducing diminutive records, there is provided a rotatable turntable and a pivoted tone arm. A pickup cartridge is mounted on the tone arm for playing records positioned on the turntable. The tone arm is counterbalanced and spring biased so that the pickup cartridge is resiliently urged into playing engagement with a record propelled by the turntable. A peripheral bearing surface is provided on the turntable to enable the turntable to maintain vertical stabili...

The invention provides interrupted coaxial-line radiators upon a ground plane and arranged in a frequency-independent manner for broadband radiation from a flush-mounted structure. The radiators may be arranged in a log-periodic array or in a spiral array for frequency-independent operation.
