Title: Thermal cracking reactor and method for operating a reactor for the thermal cracking of heavy oil
IPC: C10G9/00
Filed: 1976-10-22
Abstract: 1520825 Thermal cracking apparatus KUREHA KAGAKU KOGYO KK 22 Oct 1976 [22 Oct 1975] 44082/76 Heading C5E A reactor for the thermal cracking of heavy oil comprising a vessel 1 is fitted with at least one fluid injection pipe 4 extending into the vessel and spaced from the inner wall of the vessel, the pipe 4 has a plurality of nozzles 3 extending along its length for directing, during a decoking operation, streams of preheated uncracked heavy oil from conduit 11 against the inner wall of the vessel to scrub coke, deposited during a previous cracking operation, off the wall; a conduit 10 is provided for feeding an inert fluid through the pipe 4 to prevent clogging of the nozzles 3 during the thermal cracking. A vacuum residue of a crude oil is preheated to 490 C. and charged into the vessel 1 in which it is further heated by steam blown from the bottom of the vessel at 700 C. The thermal cracking is allowed to proceed, e.g. at 425 C. for 2 hours, while steam or nitrogen is blown through the pipe 4 at 350 C. The product pitch is then withdrawn and preheated heavy oil at 300-350 C. is injected through the pipe 4, which is rotated at 4 r.p.m., for 15 seconds to scrub coke from the walls of the vessel 1. The injected oil and scrubbed coke are left in the vessel during recharging with preheated heavy oil.

Abstract: 1408038 Tractor-trailer couplings GRAU BRAKE SYSTEM 26 Sept 1972 [25 Oct 1971] 44353/72 Heading B7T [Also in Division F2] A tractor-trailer coupling has an overrun device comprising a friction damping member 4 mounted on one coupling part and extending within another part, the one part having an abutment surface having wedge engagement with the member 4; first and second stops alternatively act on the opposite side of the member 4 each stop being carried by one of the parts, one acting during traction and the other during overrun, the wedge engagement increasing friction damping during traction as opposed to overrun conditions. A tubular drawbar 1 slides within a trailer coupling tube 2 having an anchor bar 3. The member 4 slides in the drawbar between a wedge surface 5 fixed to the bar 3 and the opposite side surface actuated by either of the stops, one defined by a ring 12 welded to the drawbar 1 and the other by a shoulder 6 on the anchor 3 by means of a disc 10 to reduce friction upon relative leftward drawbar movement (driving trailer braking); the disc can be cup shaped or have a cavity or cavities to accept member material. A further damping ring 18 may be provided between the drawbar 1 and the coupling 2. The member 4 has a smooth, corrugated, or serrated peripheral surface drawbar 1 and the coupling 2. In an alternative embodiment the drawbar 1 surrounds the coupling 2. In a further alternative, the anchor bar 3 is dispensed with, and the drawbar and the coupling forming a bearing in which the friction member 4 slides with limited displacement. Overrun causes the ring 12 to move a lever 13 to apply trailer brakes.

Title: Method and apparatus using radiation transducers
IPC: G01N23/08
Filed: 1962-12-06
Abstract: 956,112. X-ray tubes. GENERAL MOTORS CORPORATION. Dec. 6, 1962 [Dec. 11, 1961], No. 46125/62. Heading H1D. [Also in Division G1] A characteristic or condition is measured by bombarding a target with beta particles to produce X- rays, attenuating the beta particle radiation as a function of the characteristic or condition, and measuring the X-rays produced by the beta particle radiation. Thus, in an apparatus, Fig. 1, for measuring gas pressure within a housing 102 there is provided a beta particle source in the form of an elongated rod 108, a coaxial cylindrical X-ray producing target 110 and a cylindrical beta particle shield 112 disposed coaxially between the rod and target and suspended from the target by bellows 114 so as to form a gas-tight assembly. As the pressure within housing 102 varies, the bellows 114 is shortened or elongated thereby displacing shield 112 axially and varying the beta particle radiation reaching target 110. The resulting X-rays pass through the walls of housing 102 and are measured by an external detector 106 connected to a meter 120 which may be calibrated in terms of gas pressure. Source 108 is preferably strontium-90 deposited in a graphite core, the target 110 is made of tungsten or other high atomic number elements, such as uranium, lead or gold, and the shield is made of aluminium or other low atomic number elements, such as beryllium, carbon or silicon. An apparatus for measuring temperature, Fig. 2 (not shown), is of similar construction but with the source plus target and the shield mounted at opposite ends of a pair of heat expansible rods. In an apparatus for measuring the liquid level in a container, Fig. 3 (not shown), a rod forming the beta particle source projects into the liquid and the target is mounted on the wall of the container, the liquid itself serving to shield the rod to an extent determined by its level. In an apparatus for measuring displacement, Fig. 4 (not shown), a member capable of sliding in a support is connected to the element whose displacement is to be measured and carries at one end a pellet of phosphorous-32. A target of gold is spaced a short distance away and the whole assembly is immersed in glycerin which attenuates the beta radiation to an extent determined by the spacing between the pellet and target and hence the displacement to be measured. The X-ray detector comprises a scintillating crystal and photo-multiplier feeding a pulse height discriminator adjusted to detect only the characteristic X-rays of gold. An apparatus for measuring gas density, Fig. 5 (not shown), comprises a beta particle source and a coaxial target (similar to 108 and 110 in Fig. 1), the gas being arranged to enter the space between source and target so as to attenuate the beta radiation to an extent dependent on its density.

As shown in Fig. 1, a helium-neon laser oscillator 1 operating at low power in a single oscillation mode is pumped by radio frequency energy applied to electrodes 5 and has external concave spherical mirrors 4 defining an optical cavity. The gas is contained in a quartz tube 2 having its ends closed by quartz windows 3 set at the Brewster angle. The output radiation 6 is applied, e.g. through a light pipe, to a gaseous laser amplifier 7 which may use helium-neon, xenon-helium or xenon alone as the active medium. An elongated tube 8 without reflectors is used and the amplifier is pumped by a D.C. discharge between electrodes 10, 11 initiated by a heated cathode. The tube 8 may consist of quartz glass, ceramic, or plastic and the end windows 9, which may be set at the Brewster angle, may be of glass, quartz, plastic, germanium or silicon. Filters 15, Fig. 2 (not shown), may be included in the tube 8 to absorb radiation at unwanted frequencies. Modulation with the arrangement used in a signalling system may be effected by Kerr cells. The amplifier 7 may serve as a one-way or two-way repeater, and where signal transmission is effected through light pipes may have absorbing material 16, Fig. 3 (not shown), at the entrance of tube 8 to suppress those light rays out of parallel with the tube axis. Two signal frequencies transmitted over a common path 17, Fig. 4, may be amplified by the use of separate lasers 21, 25 for the two frequencies, the appropriate light rays being directed into paths 19, 20 by mirrors 18, 22, 23, 24, which are selectively reflective and transmissive at different frequencies.
