Title: Hydrogenation of petroleum fractions
IPC: C10G65/08
Filed: 1970-12-31
Abstract: 1323480 Hydrogenation of petroleum distillates CONTINENTAL OIL CO 31 Dec 1970 [31 Dec 1969] 62062/70 Heading C5E A petroleum distillate having a UV absorption for a path length of 1 centimetre of less than 0À15 at 280 to 289 nm., less than 0À12 at 290 to 299 nm., less than 0À05 at 300 to 359 nm. and less than 0À02 at 360 to 400 nm. is produced from a crude petroleum distillate containing sulphur and/ or nitrogen and/or oxygen containing impurities by first hydrogenating in the absence of a Group VIII noble metal catalyst and then hydrogenating in the presence of a Group VIII noble metal deposited on a non-acidic carrier. The crude distillate treated can be a diesel oil or kerosene, which can be de-n-paraffinized using urea or a molecular sieve, or a mixture of nparaffins with an average of 16 to 18 carbon atoms. The first hydrogenation can be carried out at 600-750‹ F. and 300-1000 p.s.i.g. using a catalyst comprising one or more oxides or sulphides of Mo, Ni, Co and W on alumina. The second hydrogenation can be carried out at 300- 500‹ F. and 200-600 p.s.i.g. using a catalyst comprising reduced platinum on alumina together with alkali or alkaline earth metal, e.g. Li, in two or more fixed beds in series with cooling between stages. H 2 S, NH 3  and water can be removed from the effluent from the first hydrogenation, this effluent can also be treated with a molecular sieve to remove n-paraffins, before the second hydrogenation.

Abstract: 1,246,030. Talking clocks &c. S. L. A. LADRIERE. Dec. 31, 1969 [Dec. 31, 1968; March 19, 1969], No.63423/69. Heading G3T. A time switch driven by a clock mechanism initiates the playback through a loudspeaker of a programme recorded on a magnetic tape e.g. clock time and advertizing. In addition circuitry is provided to maintain energization of the playback circuit even after the time switch contacts 2, 3 Fig. 1 have broken and until the programme to be reproduced is completed. In operation, when contact arm 2 moved by the clock mechanism (29) Fig. 2 (not shown) engages a fixed contact 3 a transistor 7 conducts energizing a relay 6 to close relay contacts 18, 19. Thereby a motor 20 driving a tape 21, a preamplifier 23, read-out 24 and amplifier 25 are energized from a source 5. A time constant circuit R16, C17 maintains transistor 7 conducting for a predetermined period after contacts 2, 3 break. When a recorded portion of the tape is running past the reader 24 a modulated voltage is fed to the base of a transistor 9 from the pre-amplifier 23. This voltage is amplified by transistor 9 and fed via conductor 10 to the base of transistor 7 holding it conducting even after the end of the time lag produced by R16, C17.

Class 100 (1) A device for creating and conveying a continuous line of sheets for printing comprises at least two separator members a, b, c, Figs. 2, 3, which successively come within range of one end of the sheet pile and have nozzles for suction or blast arranged at two places 3, 4 of their surfaces adapted to lift the front end of the sheet and trans er it to the opposite surface of the following separator which carries it to the sheet conveyer 2. The separators are mounted to move on a circular path and at the same time perform a tilting motion. Movement in a circular path may be effected by parallel cranks and the tilting by a bell-crank lever one arm of which is connected to the separator and the other arm of which is slotted for movement over a fixed pin, the position of the fixed pin is adjustable to regulate the degree of tilting. The separators are connected to suction and air-pressure pines there being controlling means to apply suction or pressure to the nozz'e parts 3, 4 of each separator so that the sheets are picked up and dropped again at the proper times. The operation of the device is seen from Figs. 2, 3. In Fig. 2 the top sheet I is being picked up by surface 3 of separator a while the previously picked up sheet III is released by air blast from separator c and transferred to the upper surface 4 of separator a. Fig. 3 shows the next stage in which the top sheet I is detached from the pile 1 by separator a and an air blast from surface 3 of separator b. On further rotation the sheet III on the surface 4 of separator a is transferred to the sheet conveyer 2 in the manner of sheet II shown being transferred by separator c. The next sheet is then picked up by separator b and the process repeated. Fig. 6 shows the sheet conveyer which comprises a pair of rollers 20, 21 and a perforated pulley belt 22. Suction nozzles 24 under the belt cause sheets 1 fed to the guide to be gripped and brought forward to sheet registering means 25. The nozzles 24 are adjustable longitudinally and transversely of the belt.

Title: Vehicle seat suspension
IPC: B60N2/50
Filed: 1979-01-18
Abstract: In a vehicle seat suspension arrangement in which rotation of a manually operable knob 12 can vary the preload torque in a seat-supporting torsion spring 11, the spring has a radial arm 19 carrying a first rotor 18 which bears against the surface of a cam 14 fixed to a shaft which is rotatable by the knob via a gearbox.

Title: Improvements in or Relating to Devices for Spark-erosion Machining of Workpieces
IPC: B23H7/06
Filed: 1979-02-21
Abstract: A device for wire electrode- machining for instance of intricate shapes having an inclined generatrix in workpieces 6, for e.g. diesinking, includes wire guides 4, 5 located on opposite sides of the workpiece 6. One of the guides 5 is stationarily fixed on a C-frame 2, while the other guide 4 is located on a slide-block 8 mounted in a faceplate radial guide. The faceplate 9 is mounted on a gear wheel 10 and is selectively couplable with a fixed member 21 or with the gear wheel 10. The gear wheel 10 is rotatable by drive motor 23 around the axis of the guide 5. With the faceplate coupled to the member 21 such rotation, due to engagement of a dog 13 on the slide-block 8 with a thread 12 on the gear wheel, moves the slide block along the radial guide to vary the inclination of the wire. With the face plate coupled to the gear wheel, rotation of the gear wheel causes machining of e.g. a conical aperture in the workpiece. The coupling means are solenoids 16, (17), which can be numerically controlled, and manually-actuated clamps (18), (19). <IMAGE>

Abstract: A brake master cylinder 11 has least one chamber 14 connected to a braking circuit 12, the pressure in the chamber being controlled by displacement of a master piston 24 by a brake pedal 25. An auxiliary circuit 36 connected to the master cylinder has a source of pressure 37, 37A and a jack 40, a servo piston of which cooperates with the master piston to cause displacement thereof; a distributor 46 which feeds the jack has a valve slide 47 subjected to two opposing forces, one of the auxiliary hydraulic pressure and the other by the pedal via means 50 for transmitting this force between the pedal and the valve slide, with the intervention of elastic means 51 for providing artificial feel on pedal movement. Manual back-up means 29 act on the master piston, in the event of failure of the auxiliary circuit. A movable stop member 62 in the device is associated with the elastic means 51, so as to put these means out of action in response to a failure of the auxiliary hydraulic pressure. The invention is characterised by the manual back-up means 29, the movable member 62, and the slide valve 47 of the distributor acting respectively along three separate and parallel axes. In Fig. 8 the valve is controlled through a hydraulic link and feel is provided by a spring loaded piston 94. <IMAGE>
