Title: Improvements relating to the reduction of the pour point of gas oils
IPC: C10G45/58
Filed: 1957-10-24
Abstract: A process for reducing the pour-point of a gas oil comprises contacting the gas oil, in the presence of hydrogen, with a dehydrogenation or cracking catalyst at a temperature of at least 800 DEG  F. (but below the temperature at which substantial cracking occurs) and at a pressure of at least 100 p.s.i.g. (but below the pressure at which there is a net consumption of hydrogen), the temperature and space velocity being correlated so that the pour-point of the product (after the removal of material boiling below the gas oil range, e.g. by fractionation) is at least 10 DEG F. lower than the pourpoint of the feedstock.  The feedstock may be a straight-run gas oil or may have been subjected to previous refining treatments such as hydrocatalytic desulphurization. p  Where the feedstock contains sulphur, the process of pour-point reduction may also effect a considerable reduction in the sulphur content of the oil.  The catalyst employed may be one comprising the oxides of cobalt and molybdenum (either as such or as cobalt molybdate or both) supported on alumina and preferably promoted with 0.1-6% by weight of fluorine.

Title: Pneumatic lift assembly
IPC: E04G1/22
Filed: 1973-07-12
Abstract: 1392899 Platform elevators UP-RIGHT Inc 12 July 1973 [12 July 1972] 33331/73 Heading B8H [Also in Division F2] A pneumatic lift assembly comprises a platform 15 which is elevated and lowered relative to a base 11 by means of three rams 12 (13, 14), Fig. 1 (not shown), the assembly further comprising means stopping and for securing the platform 15 in any intermediate position below its maximum elevated position in which intermediate position of the platform 15 the three rams can be over-pressurized to prevent undesired movement of the platform 15. The said means comprises a flexible cable 25, one of whose ends is located in a bracket 26 on the base 11 while its other end is wound around and fastened to a reel 33 mounted in a reel housing 30 on the platform 15, there being a ratchet wheel 35 mounted on the reel 33 for rotation therewith such that on elevation of the platform 15 the reel 33 is rotated in an anti-clockwise direction. When the platform 15 reaches a desired intermediate position lower than its maximum possible position a pawl 37 is rotated against the action of a spring 41 into engagement with a tooth 36 of the ratchet wheel 35 by depressing a foot pedal 50 on the platform 15 thus preventing the anti-clockwise rotation of the reel 33 and thereby the upward movement of the platform 15. The lifting rams can then be over-pressurized. When it is desired to elevate the platform 15 further the over-pressure is bled off from the rams on depressing a foot pedal 24 on the platform 15 and the rams begin to contract, sufficient for the cable 25 to become less tense permitting a slight clockwise rotation of the reel 33 which releases the pawl 37 from the tooth 36, the pawl returning under the action of the spring 41 to its inoperative condition so that the rams can be fed with air pressure to provide further upward displacement thereof. If during normal extension of the rams an abnormal pressure were to build up therein an inertia sensing device, Fig. 4 (not shown), would, by means of a wire 67, pull the pawl 37 into engagement with the ratchet wheel 35 thereby stopping the ascent of the platform 15.

Title: Electronic ringing generator
IPC: H04M19/02
Filed: 1963-08-23
Abstract: 1,031,927. Ringing current generators; pulse generators; switching circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 23, 1963 [Aug. 28, 1962], No. 33479/63. Headings H3T and H4K. [Also in Division H2] A ringing generator, comprises a converter 21 for converting a low voltage D.C. supply into a highvoltage D.C. supply, and an oscillator 20 which causes switching circuit 22 to connect the high-voltage supply to the output 23, at a predetermined frequency. The D.C. converter comprises a saturable core TR2, driven to saturation alternately in opposite directions by the collector currents of transistors 50, 51 which conduct alternately, change-over occurring when the feed-back voltage to the base of the conducting transistor falls off as the core reaches saturation. If the load becomes excessive the current in the emitter resistance 54 rises sufficiently to inhibit the oscillations. The secondary windings of the core feed a voltage doubler circuit which provides a centre tapped high-voltage D.C. source. Resistance 54 also improves temperature stability, by reducing the bias if the emitter-collector current tends to rise due to increase in temperature. Temperature stability is also improved by providing the base bias from a potentiometer comprising a thermistor 52 and resistance 53, the thermistor resistance decreasing with temperature to reduce the bias. In the oscillator 20, condenser 29 charges slowly over 32, 33 until the unijunction transistor 28 conducts whereupon it discharges quickly and so on to provide a spiked waveform, which causes the bi-stable circuit 25 to energize windings 38, 43 of TR1 alternately. Resistors 35, 40 in the bi-stable circuit are chosen to provide temperature stabilization. The outputs from TR1 are differentiated to provide out-of-phase waveforms whose positive peaks are used to render silicon-controlled rectifiers SCR1, SCR2 alternately conducting. Thus when SCR1 conducts positive potential from the converter is applied via winding BC of L1 to the load and condenser 67 changes to this potential. When SCR2 conducts, current flows through winding AB to discharge 67 and ultimately to reverse the polarity. This induces a double reverse polarity voltage in BC to cut off SCR1. When SCR1 is next enabled SCR2 is cut off in a similar way. Thus the output receives alternate positive and negative half-cycles of high voltage ringing current. The circuit is said to be invulnerable to variation of load up to the point where it cuts off as described above.

Title: Differential gear
IPC: B60K17/16
Filed: 1976-08-12
Abstract: An annular intermediate part (4) and side parts (2, 3) fixed to it form the housing (1) of the differential. The housing is pivotably mounted on hollow journals (2a, 3a) and driven by a pinion meshing with an annular gear (22) fixed on the intermediate part (4). Differential bevel gears (17) rotate about journals (16) fixed in a sleeve (15) and mesh with bevel gears (10, 12) rotating with axle shafts (8, 11). Thrust bearings (18) for the differential gears (17) are guided in slots (4a) parallel to the axle (20) so that they are displaceable but cannot rotate. In this way, increased wear caused by positional changes of the axle shaft bevel gears due to abrasion processes or manufacturing inaccuracies can be reduced. When designed as limited-slip differential the bevel gear (10) can be connected by way of toothing (7a, 10a) disengaging the gear (10) and a coupling gear (7) at high torques. In light trucks, friction rings (23-26) are sufficient, of which some (24, 25) are rotationally fixed to the intermediate part (4) and the others (23, 26) to the assigned gear (7 and 12). In passenger vehicles the friction rings (23-26) can be replaced by thrust bearings. <IMAGE>
