Abstract: An animal statue for simulating the drawing of a pedal-propelled or motorized carriage is provided which consists of a front section, the head of which contains a motion actuated voice box, and a rear section to be connected to the carriage to be drawn. The front section is joined to the rear section by either a coil or leaf spring. As the front section is steered to the right or to the left by reins attached to the front section, the spring resists this motion and tends to draw the front section back into alignment with the rear section thus better simulating the guiding of a horse with reins. A mechanism, such as a wheel or a caster, is coupled to each leg of the animal statue, for allowing the animal statue to travel along the ground. A structure is for steering the first travel allowing mechanism. A person in the carriage chassis can control the steering structure with a set of reins, thereby simulating the feeling of driving a real animal-drawn carriage.

Abstract: A swing propelled vehicle, having a frame set on wheels, a swing device, a steerable axle, and a braking wedge to prevent the wheels from turning in more than one direction. The vehicle is propelled by the momentum generated by the swinging motion, and the braking wedge prevents back-and-forth oscillation of the vehicle, affording forward progress. The direction of travel can be reversed by switching the braking wedge from the front of the wheel to the back and vice versa. The occupant can steer the vehicle by means of a handle that attaches to cables on a pivotally mounted axle.

Abstract: A frame (12) supporting two oscillatably movable members (16R) and (16L) for arms, and two reciprocally movable members (18R) and (18L) for feet. Cables (36) going off in pairs from each of the movable members in opposing directions, redirected by pulleys (34) toward and connected to rotatable members (14). Rotatable members (14) are coaxially connected with a sprocket wheel (42), and are also interconnected by additional cables (31) via pulleys (30) that are held back by springs (40), so as to cause one of a pair of rotatable members (14) to freely ratchet backwards while another one is turning forward. Sprocket wheel (42) is connected with a sprocket chain (44) to a vehicle propelling member (46). Handles (22R) and (22L) are connected with sleeved cables (26) to the topmost parts of movable members (16R) and (16L), and sleeved cables (26) connected at their other ends through a sleeved cable harness (282) to a steering pulley (28), that in turn is solidly connected to vehicle steering member (13).

Abstract: A modular robot may comprise a main body having a structure defined by a plurality of stackable modules. The stackable modules may comprise a manifold, a valve module, and a control module. The manifold may comprise a top surface and a bottom surface having a plurality of fluid passages contained therein, at least one of the plurality of fluid passages terminating in a valve port located on the bottom surface of the manifold. The valve module is removably connected to the manifold and selectively fluidically connects the plurality of fluid passages contained in the manifold to a supply of pressurized fluid and to a vent. The control module is removably connected to the valve module and actuates the valve module to selectively control a flow of pressurized fluid through different ones of the plurality of fluid passages in the manifold. The manifold, valve module, and control module are mounted together in a sandwich-like manner and comprise a main body.

Abstract: A three-wheeled vehicle has an auxiliary steering system which is made up of a front frame, a rear frame, a bearing element, a gear set, and a transmission element. The gear set comprises a first gear and a second gear. The first gear is fastened with the front frame while the second gear is fastened rotatably with the rear frame such that the second gear is engageable directly or indirectly with the first gear. The front frame can be caused to swivel in relation to the rear frame by means of the second gear which is actuated by an angular motion of the front fork of the vehicle when the handlebar of the vehicle is turned. The transmission element serves to transmit the angular motion of the front fork to the second gear. The auxiliary steering system is therefore capable of causing the center of gravity of a rider of the vehicle in motion to move toward a direction in which the handlebar of the vehicle is turned, thereby causing the centrifugal force exerting on the vehicle rider to be canceled out.

Abstract: A constant speed travel control system uses a time period Q which is set such that, if a motor of the actuator is not locked but normally rotated, actuator opening becomes almost certainly fully closed within that time period with the result that a first limit switch is made open. If the motor is normal, the processing operation proceeds to a normal constant speed travel control by which an electric current to the motor ceases and "motor open" condition is detected. When no "motor open" state is detected, even after the elapse of the time period Q, under the condition that the vehicle speed is higher than a reference speed, a determination that the motor is in the locked condition is made and the operation proceeds to a speed control cancellation process.

Abstract: A sprung steering system front structure, particularly for bicycles. The sprung steering front structure comprises a spring mechanism (11) with a rubber torsion spring, which between the front structure shaft (22) for the handle-bar and the upper end (3) of the shaft tube (1) is fixed in a fork (4) by means of a screw (15) passing through the fork legs (5, 6). The steering system front structure additionally has an angular position setting of the front structure shaft (22) with respect to the shaft tube (1) and an adjustability of the spring tension.

Abstract: A servo-assisted rack-and-pinion steering system is provided in which the rack cooperates with a rotatable pinion. The pinion is supported in an eccentrically located opening in a circular disk rotatably mounted by rolling elements on its periphery. Pivoting movement of the pinion controls an hydraulic oil actuated servo motor. The rolling contact bearing of the disk lies in the path of flow of the hydraulic oil for the servo motor. The pinion is supported in a bearing in the opening in the disk and another bearing at an opposite side of the rack and separate from the disk.

Abstract: Transducer structure for a steerable axle includes a transducer assembly having a housing and a cup-shaped journal, having an apertured bottom portion, fixed to the spindle of a steerable wheel by the spindle bolt for rotation with the spindle about the spindle axis. A bracket connected to the guide axle knee nonrotatably supports housing structure above the spindle, and the journal is rotatably received within a bearing and seal in the housing structure. The journal includes apertures which receive mating pins which constrain the rotary member for rotation with the journal relative to the housing structure. A special fixture supported by the tie-rod bolt accurately centers the journal during assembly and facilitates calibration of the transducer.
