Title: Improvements in brake mechanism
IPC: B60T8/26
Filed: 1929-12-23
Abstract: 342,846. Brakes. BRAGG, C. S., Palm Beach, Florida, and KLIESRATH, V. W., Port Washington, New York, both in U.S.A. Dec. 23, 1929, No. 39298. Convention date, Feb. 1. [Class 103 (i).] The friction elements of one brake or set of brakes of a group are adapted to heat up or to distort more readily during braking than those of another or another set of the group so that the ratio of the braking effect of the two brakes or sets of brakes increases as the applied pressure increases. An increasing ratio of the braking effect on the front relatively to the rear wheels of a passenger motor vehicle or of that on the rear relatively to the front wheels of a goods vehicle may thus be obtained. Fig. 1 shows a passenger vehicle provided with an hydraulic brake system comprising a pedal-operated pressure cylinder 4 supplying cylinders 11 for expanding the shoes of internal brakes. Light steel brake drums, Fig. 7, A or C are provided for the rear brakes, but the front drums have heat dissipating and strengthening ribs 26. When the brakes are applied the rear brakes become more heated than the front brakes and their efficiency is relatively decreased by the consequent greater fall of the coefficient of friction and the distortion of the drums, the distortion causing the outer or central part of the drums, Fig. 7, A, C to separate from the shoes and decrease the area of contact, this distortion being further increased directly by the pressure of the shoes. The ratio of the efficiency of the front to the rear brakes increases approximately in proportion to the applied braking pressure and thus also to the increasing ratio of the load on the front to that on the rear wheels brought about by the deceleration of the vehicle. A goods vehicle having a mechanical equalizing transmission system for the four brakes is also described. In this case the ribbed and plain drums are respectively provided on the rear and the front wheels, thus giving an increased relative efficiency to the rear brakes when the necessary greater braking pressure is applied for a loaded vehicle. When external shoes are used these may be provided with heat dissipating circumferential ribs and external brake bands may have a series of transverse ribs.

Title: Improvements in or relating to the pyrolytic cracking of light petroleum fractions
IPC: C10G9/28
Filed: 1958-12-18
Abstract: In cracking light petroleum fractions in the presence of fine-grained solid heat carriers and passing the products through a waste heat boiler, the amount of entrained solid heat carrier material in the product entering the heat exchanger is controlled so that deposits on the heat exchange surfaces are readily removed during operation by mechanical action, e.g. by the use of shot. Preferably the solid content is arranged so that the deposits on the heat exchange surface contain at least 30 and preferably above 50% of solids, e.g. by adjusting the solids entering the heat exchanger to 0,05-0,5, preferably 0,1-0,4 part by weight per 100 parts of crude charge to the process.  This may be achieved by the use of a suitably dimensioned cyclone for separating the solids or by introducing a rising gas into the bottom of the cyclone.
