Filed: 1990-03-30
Abstract: A solid front wheel for cycles (partic. push bikes) has a rim with tyre, a hub with the wheel axle held by a fork, a brake, and a wheel plate of composite plastic material between hub and rim.  The brake is a disc type with its disc on the hub; the hub is attached to the axle, so that braking force is transmitted outwards approx. at right angles to the axle. The wheel plate is preferably made of a foam, pref. epoxy acryl or polyurethane resin, or honeycomb, pref. paper, Kevlar (R.T.M.) or polycarbonate core with laminar skins, and aramid or carbon fibre skins. The hub is pref.  aluminium, titanium or manganese alloy, or steel; the rim is pref.  metal, wood or plastics. The wheel plate (1) pref. has an e.g., epoxy adhesive between the hub (18) and/or rim (19) and wheel plate (1). The plate (1) is held between radial flanges (21, 22) on the hub (18); the hub (18) is in two parts of which the second (2) receives the part (11) to which it is fixed, e.g., by screws. ADVANTAGE - The structure provides reliable braking effect without using rim brakes. It overcomes the earlier problems of, e.g., fusion of a heated plastic brake, etc..

Patent DE-4035777-A1 (DE)
Inventor: LORSON HEINZ DR ING
IPC: C03C6/10
Filed: 1990-11-08
Abstract: The invention relates to a method of disposing of dusts containing toxic heavy metals, toxic organic substances and similar compounds and preferably originating from flue gas purification from, for example, refuse incinerators. The dusts are mixed with one or more additives to give a fusible blend and thermally treated. The glass formed can be taken to a higher-value re-use, and the hot waste gases arising during the fusion process are mixed with the dedusted and cooled waste gases of the refuse incinerator directly upstream of the entry to an HCl scrubber. Cooling to temperatures of 45 DEG  to 80 DEG C is effected by injection of aqueous hydrochloric acid and/or water. The dilute hydrochloric acid formed in the HCl scrubber is separated by rectification into concentrated hydrochloric acid and a bottom fraction. The heavy metal compounds, salts and residual dusts which have remained in the dedusted flue gas and in the waste gas of the fusion process are enriched in the bottom fraction, separated off and must then be put into a landfill. <IMAGE>
