Title: Separation of asphalt-type bituminous materials
IPC: C10C3/08
Filed: 1957-12-23
Abstract: An asphaltic material containing asphaltines is separated into at least two fractions, one of which contains the asphaltines and is free from resins and oils, by treating each volume of the material with at least two volumes of a solvent comprising at least one C 4-8 paraffin hydrocarbon, the temperature being at least 175 DEG F. and sufficient to allow a bulk interface its form between a separated asphaltine fraction and the solvent solution of residual materials, the temperature and pressure being adjusted to give a solvent density at least as great as K \sS Mol-wt. (K being between 3,5 and 4,3) but less than that density at which no liquid phase separation of asphaltines occurs, and separating the asphaltine fraction while in the liquid phase.  The other fraction can be separated into resins and oils by a similar treatment but at temperatures and pressures relating to a solvent density between 0,23 and K \sS Mol. wt. Preferred solvents are normal and isopentane.

Title: Method and apparatus for trimming and cutting a moulded ceramic component such as a handle
IPC: B28B11/18
Filed: 1976-10-06
Abstract: 1515607 Trimming moulded ceramic handles V E WISSENSCHAFTLICH-TECHNISCHER BETRIEB KERAMIK 6 Oct 1976 [9 Oct 1975] 41552/76 Heading B5A In apparatus for trimming and cutting freshly moulded ceramic handles prior to attaching them to vessels, pairs of handles each attached to a core 1 are located upon supports 3 and 4 carried by plates 38 themselves releasably supported upon a turntable 2. The handles are indexed to a station III at which a resiliently supported vibrating member is lowered into contact with the handles to cause a smoothing out of the irregularities in the handles by thixotropic flow. The handles are then indexed to a station V where the ends of the handles are cut to conform with the surface of the vessels to which they are to be attached. Cutting is effected by blades 27, 28 (see Fig. 4) carried by arms 21, 22 pivoted to levers 19 and 20. The levers are pivotable by cylinders 17, 18 to position where their free ends abut stops 23 and 24 respectively. Further movement of the levers causes the arms 21 and 22 to pivot relative to the levers, against the action of springs 31, 32, and the blades to effect the cutting operation. Retraction of cylinders 17 and 18 causes withdrawal of the blades &c. to their initial positions. The cut and trimmed handles are then indexed to a station VI at which they are transferred on to a take-off conveyor 51. Transfer is effected by a pair of electromagnets 44, 45 mounted upon the ends of arms 39 and a take-over plate 50 carried at the end of an arm 46. In operation, the plates 38 are bodily picked up by the electromagnets on arm 39 and pivoted to a position at which they are transferred on to the take-over plates. The arm 46 is pivoted to bring the take-over plates to a position above the take-off conveyor and the handles slip from the take-over plates on to the conveyor. Alternatively the take-off conveyor can be replaced by a second turntable. In a further alternative (see Fig. 6, not shown) the plates 50 are deposited on to the take-off conveyor and the arm electromagnetically picks up an empty plate for receiving the next handle.

Abstract: 1491711 Control of D.C. motors ROBERT BOSCH GmbH 18 Oct 1974 [19 Oct 1973] 45161/74 Heading H2J [Also in Division B7] A motor vehicle steering system comprises a gearbox having a plurality of forward gears and a reverse gear, and an electric motor for influencing steering linkage movement in a direction corresponding to a manually steered direction, at least the lowest forward gear and reverse gear, but not at least the highest forward gear, having a switching arrangement associated therewith which is actuated on engagement of one of the associated gears, the motor only being energizable when said arrangement is actuated. As illustrated in Fig. 1 switches 14, 15 are closed upon first gear and reverse gear, respectively, being engaged. With one of these switches closed and upon closing switch 18 or 19 in dependence on the movement of contact 20 by the steering wheel, the appropriate solenoid 16, 17 will actuate its contact 21 or 23 to energize electric motor 10 which assists the manual steering. In the system of Fig. 2, switch 32 is closed by engaging of first and reverse gear, switch 30 is closed by selection of second gear and switch 31 is closed by selection of third gear. The fourth gear has no switch associated therewith. As a higher gear is selected so the maximum torque developed by the motor is reduced by closure of switches 34, 35, 36 which determine whether none, one or both of resistors 37, 38 are connected in series with the motor. Alternatively these resistors may be replaced by a variable resistor whose resistance is caused to vary in dependence on the vehicle speed, e.g. by a centrifugally operated adjusting device. In a further system similar to that of Fig. 1 the operating current of the motor is adjusted in inverse proportion to the voltage produced by a tachogenerator (51) responsive to vehicle speed, this voltage being applied to a differential amplifier (61) controlling a transistor (62) in series with the motor, Fig. 4 (not shown). Feedback of motor current to the amplifier (61) ensures constant current operation for the existing vehicle speed.

Conveyer means 30, 32 transports a flow of aggregates from compartment 24 and into the front end of the drum and receiving means 110, 112 adjacent the rear end of the drum receives the heated and dried aggregate from the drum and discharges it into mixing means 116, 118. Liquid bitumen is automatically discharged and metered into the mixing means by means 120-122. The arrangement of the apparatus is such that the flow-path of aggregates from storage compartment 24 to mixing means 116, 118 extends along substantially straight lines. In the particular embodiment, the aggregate is conveyed out of chambers 40, 42 by substantially horizontal conveyer 30 passing beneath the open bottom sides of the chambers and through metering gates 48, 50 controllable by hand wheels 60, 62, Fig. 5. Bucket conveyer 32 receives the aggregate and transports it to auger 70 and thence it is passed into drum 34. Burner 92 is attached to blower 96 to provide forced hot air in the drum whence it is extracted by blowers 106, Fig. 5, through channels and into the chambers 40, 42 for pre-drying the aggregate and removing dust from the drum. Dried aggregate moves down the inclined drum and falls into hopper 36, Fig. 3, whence it is fed by rotary conveyer 112 through metering gate 110, Fig. 7, into funnel 116 of the mixing means where it is joined by bitumen from pipe 120. The mixer is an auger-type pug mill 118. The aggregate and bitumen are synchonized to be fed together by mechanism 124-132 which is actuated by the weight of aggregate in the hopper to switch on motor 130 of conveyor 112 and pump 122 for the bitumen. The mixture drops from the mixing means into a spreading device 38 for spreading it onto the road (see Division E1)
