  • 1-Alkyl-4-isopropylbenzene desorbents for para-xylene
    Patent number: 4139572
    Abstract: Para-xylene is selectively adsorbed from a C.sub.8 aromatic hydrocarbon feed by a crystalline selective adsorbent, and then the para-xylene is subsequently desorbed by contacting the resulting adsorbent with a 1-(lower alkyl)-4-isopropylbenzene desorbent, wherein the lower alkyl group contains one to two carbon atoms. The desorbent effectively desorbs the para-xylene from the adsorbent, and the para-xylene may be produced as an enriched product.

  • Disc brake
    Patent number: 4109766
    Abstract: A disc brake of a type having a pair of main and auxiliary guide pins for guiding a caliper in the axial direction of a rotor. The main guide pin is secured to a support while the auxiliary guide pin is removably screwed to the caliper. For replacing a pair of friction pads, the auxiliary guide pin is removed and the caliper is turned round on the main guide pin to expose the friction pads to the outside to permit access thereto.

  • Disc brake of floating caliper type
    Patent number: 4072217
    Abstract: A disc brake of the floating caliper type has a pair of laterally spaced guide pins each slidably engageable at one end within a boot provided in a receptor hole in a caliper and rigidly secured at the other end to a support plate for the caliper. For facilitating the replacement of friction pads, displacement between the support plate and one of the guide pins is provided so that in replacing the friction pads, it is only necessary to loosen one of the guide pins and then to rotate the caliper about the other guide pin.
