Abstract: A suspension system that requires minimal or no welding and can be easily adapted for use with a variety of frame configurations without adversely affecting the frame integrity. One embodiment includes a top bearing (21), a base bearing (31), an upper clamp (19), and a strut (41). The bearing inserts may be secured with conventional fastening means, for example, adhesives or screws. In one embodiment, a lower spring seat may be secured with a snap ring and heat sensitive materials may be used. Thus, the suspension systems may, if welding is necessary, be installed using standard frame welding practice without the need for extraordinary or special fixtures or procedures. Options are thus now available in component material selection and suspension configuration which have previously been limited because of the heat of welding. This frame integral technology may be used with only minor changes to current fabrication practices.

Abstract: For damping undesirable whipping of a bicycle sprocket chain, especially of a mountain bike when it is being ridden rapidly downhill over rough terrain, and thereby preventing chain suck, a segment of the return run of the chain extending tangentially forwards from the pitch circle of the idler sprocket towards the pitch circle of the drive sprocket in use, is encased within a tube. The tube is mounted by a bracket to the axle of the idler sprocket, and is loose and slippery enough to permit desirable running of the drive chain, while restraining and preventing undesirable deviations, especially in a vertical plane (i.e., transversally or laterally of the running path of the drive chain). Conveniently, the tube may be a self-recoiling longitudinally split member for ease of installation on the chain, and its bracket can be springly clipped over the conventional mounting structure of the idler sprocket.

Abstract: A cycle-like exercise device for enabling post operative exercise by a patient while in bed. The leg exercise device is mountable to a bedframe and has a pedal mounting structure extending upwardly therefrom. Pedals are rotatably mounted to the pedal mounting structure so that when a patient's feet are engaged with the pedals of the exercise device, cycle-like exercise of the patient's legs is possible.

Abstract: A portable automotive jack is provided having a generally triangular configuration defined by first and second pairs of pneumatic cylinders. Specifically, the cylinders of one of the pairs of are spaced apart from one another and straddle the cylinders of the other pair so that the pairs of cylinders define the legs of a triangle. A lift plate is mounted to the upper ends of the hydraulic cylinders at the apex of the triangle whereby actuation of the cylinders moves the lift plate relative to the base member to permit jacking of a vehicle therewith. The jacking assembly, by virtue of a common source of air pressure and flexible mounts, adjusts in angle and position to accommodate changes in angle of the vehicle as it is bieng jacked thus providing a device which has an inherent stability and relative insensitivity to the hardness and flatness of the jacking surface and the construction of modern cars.

Abstract: An orifice fitting for a gas pressure differential-measuring system is constructed of a fabricated body. In the fabrication, two lengths of flared or flanged pipe are inserted through the internal bores of respective orifice blocks and circumferentially welded on the outside. A U-member, which may be assembled of three straight pieces, is welded between the two blocks joining them and leaving a slot at the top. An orifice holder dependingly secured to a cover is provided with an orifice plate rimmed within a gasket and inserted through the slot. The cover is removably, sealingly mounted on the body. The outer face of the upstream face of the gasket is radially notched to equalize pressure in the orifice chamber.

Abstract: An angle iron forms two sides of a right isosceles triangular housing. These sides are each apertured and the apertures are provided with metal-framed lens plates which bolt onto the housing sides. Preferably, in one instance the lens material is mounted in the plate for ease of access to the interior of the housing and in the other instance the lens is mounted in the aperture and retained by the frame plate. A fluorescent lamp tube assembly is received inside the housing for providing illumination through both lenses. Access thereto is via removal of a metal-framed lens plate. The housing has mounting elements which permit a user to flush mount the housed light source, e.g. on a mining machine.

Abstract: The present invention provides a tension-setting edge clamp with an improved linkage and an improved anchor point location so that when in use in sets of pairs, to pull broken belt ends toward one another for reconnection, wherein the anchor point for the center of pull on each clamp is aligned with the center of the clamping jaws of the same clamp, to minimize belt twisting, yet not interfere with the site of the adjoining broken edges. This eliminates a cause of belt rupture and tearing, yet provides space for the reconnection to be made.

Abstract: The light has an explosion-proof housing that is of generally triangular transverse section, with no glass on the narrow front or top wall. In mine use, should rock drop onto the housing it is likely to strike glass parts only a glancing blow. The glass parts are arranged to be resiliently sealed to the cast or fabricated metal body of the housing, but be removable from the outside, so a broken glass part need not cost a whole light fixture. A spring resiliently supports the outer end of the bulb upon the housing to cushion against mechanical jolts.
