Title: Improvements relating to the distillation of tar
IPC: C10C1/04
Filed: 1921-06-07
Abstract: 184,624. Thermal, Industrial, & Chemical (T.I.C.) Research Co., Ltd., Morgan, J. S., and Rider, D. June 7, 1921. Hydrocarbons, distilling.-In distilling tar by passing it below the surface of molten metal, the metal is either heated to such a temperature (about 350‹ C.) that the unvolatilized residue is a hard pitch or is heated to 275-290‹ C. to obtain a pitch containing anthracene. In the latter case, the pitch is afterwards sprayed with superheated steam to separate anthracene, the vapours being cooled to 100-104‹ C. to separate anthracene without condensing the steam. The volatile constituents may be fractionally condensed. Tar from a tank c is pumped through a heat-exchanger e and fractionating column f and enters the still a beneath the surface of molten metal maintained at 275-290‹ C. The vapours pass to the column f, which has a temperature of about 120‹ C. Uncondensed vapours consisting of light oils and water vapours pass through the exchanger e to a condenser h. The condensate from the column f passes to a second still m containing molten metal kept at about 230‹ C. The vapours pass to a heat-exchanger k and condenser alpha and the residue to a cooler p or to a third still maintained at about 270‹ C. The residue from the still a passes to a tower r, where it is sprayed with superheated steam. The vapours pass to a condenser t kept at about 100-104‹ C. to condense the anthracene, while the steam may be returned to the tower r through a superheater.

Inventor: BLACKLEDGE JAMES
IPC: A21C9/08
Filed: 1916-11-07
Abstract: 111,132. Blackledge, J. Nov. 7, 1916. Shoots.-Apparatus for dividing a travelling series or stream of articles, such as dough pieces used in the manufacture of bread, into two or more streams automatically, consists essentially of a hopper A, in which is pivoted below its centre of gravity an inclined oscillating plate D, which when the article falls on it, directs the article in a certain direction but is itself turned on its pivots by the weight of that article so as to be inclined in the opposite direction, whereby, when the next article arrives, it is directed to the opposite side and the plate is returned to its original position. In the example shown, the dough piece F is brought by a conveyer F, and falls into the hopper, from which it is directed down the shoot B to another conveyer G. The next piece of dough is directed by the plate D, which is now in the position indicated by dotted lines, to the shoot C and falls on to the conveyer H. The shoots may be omitted. If it is desired to divide the stream into more than two streams, the device can be duplicated at the bottom of either or both shoots.

Title: Improvements in and relating to methods of and apparatus for seismic prospecting on land
Inventor: CHOLET JACQUES
IPC: G01V1/112
Filed: 1966-04-13
Abstract: 1,145,125. Seismic prospecting. INSTITUT FRANCAIS DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. 13 April, 1966 [13 April, 1965; 31 Aug., 1965]. No. 16157/66. Heading H4D. In a system for generating seismic waves an explosive charge is detonated in a liquid-filled chamber having a deformable base in contact with the ground. In the embodiment of Fig. 3 an explosive cartridge 12 is forced down tube 13 from a loading device 14 by fluid pressure established by a pump 19 supplying fluid to a valve 15 and is exploded in a liquid-filled chamber 1. Combustion gases are removed from the top of a chamber extension 3 by the pumped liquid. The pressure pulse of the explosion is transmitted to the ground through a deformable base member 2, but secondary pulses due to oscillations of the combustion gas bubble are suppressed by the provision of a perforated sphere 7 to break up the bubble. A further seismic pressure pulse due to chamber 1 rising and falling back to the ground is prevented by providing hydraulic or pneumatic jacks 29 which permit the chamber to rise rapidly but cushion its fall. A screen of air bubbles to protect the chamber side wall from shock wave damage may be provided by means of a perforated member (4) (Fig. 2) at the base of chamber 1. The cartridge loading and firing systems may be as disclosed in Specifications 1,097,227 and 1,120,023. In a second embodiment (Figs. 5 and 6), the hydraulic jack system is replaced by a single piston (39) coupled to chamber extension 3 and moving in a fluid filled cylinder (36) secured to an enclosure (28) surrounding chamber 1, and the perforated sphere is replaced by two part-spherical perforated screens (34) secured to extension 3. In a third embodiment (Fig. 8) the chamber 1 is prevented from leaving the ground by the provision of bolts (57) for anchoring it to the ground. In a fourth embodiment (Fig. 9), the explosive cartridge system is replaced by a system for electrically firing an explosive liquid mixture, the constituents of which are supplied to the perforated sphere 7 through conduits (59 and 59a). Details of a system for mounting the seismic wave generator on a transport vehicle, in which a pneumatic jack is used to raise the generator from the ground for transport and also provides cushioning for its fall, are given (Figs. 7 and 7a). In a seismic exploration method the generator may provide repetitive pulses and the respective recorded traces may be summed to improve signal-to-noise ratio.

Title: Battery state-of-charge indicator

Filed: 1974-04-11
Abstract: 1434435 Battery state-of-charge indicator TOYOTA CHUO KENKYUSHO KK 11 April 1974 [16 April 1973] 16347/74 Heading G1U The dependence of the battery capacity on load current is allowed for by modifying a voltage indicating discharge current by a factor mI<SP>n</SP> B , where I B , is the discharge current and m, n are constants determined by experiment for a particular battery from an equation C = m/I<SP>n-1</SP> where C = battery capacity and I is the load current. The modified voltage is integrated and substracted from a theoretical fully charged capacity before being indicated. Temperature compensation may also be effected either on the modified voltage or on the initially measured voltage. In the Fig. 8 embodiment, a linear approximation to the required relationship is used Fig. 4 (not shown). In an electrically driven vehicle, the motor M current drawn from battery 11 is controlled by a thyristor 12 and monitored by a shunt resistor 1a. The voltage across the resistor is amplified 2 and fed to the compensation circuit 3. This contains three resistor chains connected to diodes 307-309 which become forward biased at different input levels due to the values in the resistor chains. As each diode conducts, the effective gain of the negative feedback amplifier 311, 310 is altered to give three different slopes in the output characteristic at different input levels Fig. 5 (not shown). The modified voltage is fed via thermistor 802 mounted on or in the battery. This allows for the temperature dependence of the battery capacity Fig. 7 (not shown). This further modified voltage is applied via resistor 401 to an electrolytic integrator 402 which is preconditioned by closing switch 408 to store a value corresponding to the theoretical capacity. Thus as switch 407 is closed  when motor M is running, the store integrates the  modified voltage to indicate the actual state of charge. This is indicated on a meter 505 in a bridge arrangement including transistor 503 in one arm. The transistor collector-emitter resistance is varied by the voltage output from the store transmitted via a high input resistance FET voltage follower 501. In a second embodiment, the modifying relationship is approximated by a single straight line Fig. 6 (not shown), this being effected by a resistive network (6), (Fig. 5).
