Abstract: An axial fixing and closure member arrangement including an insert element for producing a rotatable, but axially fixed connection between the rotary axle of the chain guide of a rear gear change mechanism for bicycles and the related lower pivot head by means of a spring element, wherein additionally the insert element also has a sealing effect by providing an integrated closure member.

Abstract: A stable and play-free pivot connection of a bicycle derailleur between a parallelogram link and either a base member or a chain cage. The pivot points are formed with first and second bushings that are arranged as far from one another as possible. The parts are connected by pivot pins having a anti-rotation contour for preventing rotation of the pin within an inner pivot part. The axial displacement of the pivot pin is prevented by a securing element or by a deforming element engaging a holding contour on the pivot pin. One of the first and second bushings is protected and arranged in a blind hole and the other of the first and second bushings is covered on the outside by a pin head of the pivot pin.

Abstract: A trigger shifter for operating a bicycle gear change device that includes a housing mountable to handlebar, a cable spool for pulling and releasing a control cable connected to the gear change device, a pull lever mechanism and a release lever mechanism. The pull lever mechanism includes a pull lever rotatable about a first axis defining a first plane of motion perpendicular to the first axis. The release lever mechanism includes a release lever rotatable about a second axis defining a second plane of motion perpendicular to the second axis. The first and second planes of motion form an angle therebetween in the range of 20 to 70 degrees.

Abstract: A chain guide of a bicycle derailleur for displacing a chain between gears that includes inner and outer side plates, a pivot shaft and a thermoplastic connector. The pivot shaft pivotably connects the chain guide to the bicycle derailleur. The thermoplastic connector injection molds the pivot shaft to one of the inner and outer side plates.

Abstract: The invention relates to an aid (10) for facilitating learning how to play golf. This aid is attached to a golf club having a club head and shaft, and can be mounted on the club head or on the shaft of the golf club while being located in the vicinity of the club head. Said aid comprises a device (22) that redirects the image, which, starting from the device, can be viewed in the line of sight perpendicular to the leading edge of a striking surface of the club head, toward the head of a golf player who is using the aid. This device is fastened to the club by means of magnets.

Abstract: A hot water supply system is provided, which includes a ring pipeline which extends through a water heater and in which water circulates, before going through tap pipelines to taps. The circulation pipelines have a substantially smaller cross-section than that of the tap pipelines. The circulation pipelines extend, for a portion thereof, in the interior of the tap pipelines before terminating openly in a region of a tap. A pipe branch piece is included, which is in the form of a continuous pipe and forms a component of the tap pipeline. A branch pipe of the pipe branch piece receives the circulation pipeline. The branch pipe forms an acute angle with the tap pipeline, with the angle being opened opposite to the flow direction in the tap pipeline. The section of the circulation pipeline, which extends to the tap, is inserted endways into the branch pipe, while the remaining section of the branch pipe joints at the branch pipe and at the ring pipeline.

Abstract: An instrument has a rotatable part and a helical spring secured to the instrument casing at its outer end and to the rotatable part at its inner end. The spring characteristics are made to depart from linear, by changing the cross-sectional area of the spring progressively substantially from one end to the other of the spring. Preferably, the spring thickness is kept constant and its width varied, as by providing a tapered slot through the spring along its length. Provision is made for further selectively varying the spring characteristics, by rendering inactive selected lengths of the outer turns of the spring. In one embodiment (FIGS. 1 and 2) this is done by providing a split ring that encircles the spring and whose ends can be moved toward or away from each other to contact selected lengths of the outer turns of the spring. In other embodiments (FIGS. 3 and 4) a helical rib coaxial and coextensive with the spring is rotated relative to the spring to contact varying lengths of the inner (FIG.

Abstract: An instrument for continuously indicating the instantaneous rate of fuel consumption (e.g. in terms of liters per 100 kilometers) during operation of a motor vehicle comprises a stationary speed scale juxtaposed with a movable consumption scale, the two scales carrying relatively inverted logarithmic graduations and being swept by a common pointer driven through a gear train from a speedometer biased by a spring of logarithmic characteristic. The movable scale is magnetically entrained, via a friction coupling, by a flowmeter which is thermostatically controlled to take changes in fuel viscosity due to temperature variations into account; the friction coupling can be manually preadjusted in accordance with the specific weight of the fuel. The pointer and the movable scale are carried by two coaxial disks that coact through a differential coupling with a switch which energizes different signal lamps according to whether, at a given speed, the rate of fuel consumption is normal, subnormal or excessive.

Abstract: A flow-rate meter has a cylindrical housing in which a counterweighted blade is pivotable on a shaft about the axis of the housing which is subdivided by a radial partition, an inlet port and an outlet port opening axially into this housing on opposite sides of the blade. The blade is magnetically coupled with a logarithmic scale and is provided with a logarithmic spring against which the force of the water flowing past the blade works.
