Title: Improvements in or relating to the hydroforming and hydrofining of naphthas
IPC: C10G69/14
Filed: 1951-11-06
Abstract: A virgin naphtha is hydroformed using a fluidized catalyst, catalyst is withdrawn to a fluidized solid regeneration zone wherein carbon is burned off, part of the catalyst is then recycled to the hydroforming zone in addition to part of the process gases, another part of the catalyst is fed, together with the excess of process gas, to a secondary fluidized catalyst zone wherein a second feed stock such as cracked naphtha, virgin naphtha from sour crudes or a heating oil stock is treated under the same pressure as in the hydroforming zone but at lower temperature and higher space velocity to desulphurize and stabilize it, and catalyst is then recycled to the regeneration zone.  The hydroforming is effected at 850-950 DEG F., 100-500 p.s.i.g., and, e.g. .15-1.5 lbs. feed/lb. catalyst/hour, the ratio of catalyst to oil being 0.5-1.5.  A ported conduit extending above the catalyst bed takes off spent catalyst countercurrent to a stream of stripping gas, the catalyst then being carried by an air stream to the regenerator.  Regenerated catalyst is discharged through a standpipe and carried by excess process gas to the secondary treating zone which is also fed with the second feed stock.  Spent catalyst is led off against a stream of stripping gas and returned to the regenerator.  The regenerator operates at 1,050-1,200 DEG F., and the secondary treating zone at 400-750 DEG F. and 0.5-5 lbs. feed/lb. catalyst / hr.ALSO:A virgin naphtha is hydroformed using a fluidized catalyst, catalyst is withdrawn to a fluidized solids regeneration zone wherein carbon is burned off, part of the catalyst is then recycled to the hydroforming zone in addition to part of the process gases, another part of the catalyst is fed, together with the excess of process gas, to a secondary fluidized catalyst zone wherein a second feed stock such as cracked naphtha, virgin naphtha from sour crudes or a heating oil stock is treated under the same pressure as in the hydroforming zone but at lower temperature and higher space velocity to desulphurize and stabilize it, and catalyst is then recycled to the regeneration zone.

Title: Circuit arrangement for subscribers' stations
IPC: H04M1/26
Filed: 1960-07-29
Abstract: 954,211. Substation circuits. STANDARD TELEPHONES & CABLES Ltd. July 29, 1960 [Aug. 4, 1959], No. 26432/60. Heading H4K. In a substation including a transistor circuit arrangement supplied with power from an exchange, a calling signal from the exchange causes the transistor to oscillate whereby a voice frequency signal is produced which is fed to the telephone receiver as an audible calling signal and is also reverted over the line wires as an indicating signal to the exchange that the subscriber is being " rung." The reverted signal is used to release exchange equipment associated with the connection, e.g. register, common control equipment &c. The transistor is also used in conjunction with a subscriber's key sender as an oscillator for producing voice frequency " dialling " pulses. The substation may be called using conventional alternating ringing current which is rectified at the substation 01 by applying negative battery to one or both line wires. In the system shown battery is applied to wire b, and transistor Trs is thereby caused to oscillate, the frequency of oscillation being governed by capacitor C3 and winding VI of the speech transformer U2. The V.F. signal produced is fed via winding III to the receiver F and is also returned over wire b to the exchange. When the handset is lifted, cradle switch contacts Hu1 and Hu2 operate, the transistor then acting (by means not shown) as an amplifier for outgoing speech. In addition voice frequency dialling pulses can be produced by operating keys T1-T0 (and T1<SP>1</SP>-T0<SP>1</SP> linked thereto), these keys causing one or two out of four capacitors (only C1, C2 shown) to be shunted across winding VI. It is mentioned that there may be two transistor circuits, so that a two-out-of-five voice-frequency dialling code can be used. The voice frequency return signal may also be used to identify the subscriber or to indicate his class of service.

Title: Improvements in direction indicators for motor road vehicles
IPC: B60Q1/34
Filed: 1926-10-25
Abstract: 269,803. Wiesener, W. G. Oct. 25, 1926. Road-traffic signals on vehicles.-In a signal device comprising lamps and a movable signal arm housed in a common casing and operated in common by manually operated means, these manual means are controlled by a lever which is operated by the driver's knee. Bowden wire mechanism is used, the movement being stepped up and down before reaching, and after leaving, the Bowden wire respectively, to give sufficient rotation to the wire to distinguish clearly the various signals. A pilot device in the form of an arrow is mechanically geared to the main signal device and is illuminated by a dash-lamp. A spring-biassed telescopic knee-lever 14 is pivoted at 12 to a bracket 10 on the instrument board 11 and oscillates between stop screws 16, 17. A link 18 attached to the inner end of the lever 14 is also pivoted to an arm 19 loose on a shaft 21 and carrying a pawl 22 which coacts with a four-toothed wheel 24 rigid with gears 31 and 25. The gear 31 moves the pilot arrow 32 which is illuminated by a dash-lamp 33 and the gear 25 drives a gear 29 attached to Bowden wire mechanism 28 in the ratio 4: 1. Thus for each 90‹ oscillation of the knee-lever the pawl 22 rotates the gear 25 90‹ giving a complete rotation to the Bowden wire. At the other end this wire is geared in the ratio 1 : 4 to a shaft 69 through gears 73, 72, 71. This shaft is housed in a casing 60 having glass panels 64 and screwed rods 62 for attachment of the signal device to a rear mudguard. The shaft 69 carries two arrow arms 70. The parallel circuits of three lamps 81, 82, 83 are closed by contacts 39, 40, Fig. 6. Attached to the shaft 30 of the pilot device 32 is a cam 34 having a flat 35 for one quarter of its periphery and coacting with a blade 36 carrying the contact 39. Fig. 6 shows the parts in normal positions for the arrow pointing downwards. If, in this position, the brake or clutch pedal is depressed a spring rod 43, 44 attached to the pedal pulls down a blade 45 to close the contact 39, 40 illuminating the arrow arm in its downward position. If, however, the knee lever 14 is operated to move the arrow arm the cam 34 is rotated, closing contact 39, 40 and lighting the lamps. The dash-lamp 33 is also lighted in parallel. The wheel 24 and hence the arrow arm are always rotated in one direction so that for a " left signal, for instance, the knee lever must be moved three times to pass the arrow arm through "right" and upper positions to " left " position.

[Also in Division F1] Apparatus for dispensing a pressurized drinking fluid such as beer includes a beer  keg 1 connected to a cylinder 2 containing carbon dioxide under pressure and to the inlet side of a gas operated pump 3 below  the keg, the pump consisting of the cylinders 5 each having an inlet valve 6 and outlet valve 7 and containing a double headed piston 8 operated by gas supplied under constant pressure via valves 9, 10. The dispensing device 4 consists of a cylinder 11 with inlet 12 and outlet 13 and a piston head 14, the outlet 13 being connected to a delivery valve 15. When valve 15 is opened the pump functions automatically in response to a drop in pressure on the outlet side, beer enters the cylinder on the inlet stroke and is forced out of the pump under pressure from the gas operated piston. The beer enters an inlet 12 of dispensing device 4 and the pressure moves piston head 14 until the cylinder is full. Friction between the piston head and cylinder ensure that sufficient pressure is maintained on the beer to prevent it foaming in the cylinder. In a modification (Fig. 2) the dispensing device is a single delivery valve connected to pump 3, adjustment of the size of the orifice providing frictional forces which ensure sufficient pressure is maintained on the beer to prevent foaming. Valve 4 is also connected to electrical switch mechanisms 12, 19 which control a circuit including solenoids 15, 16 actuating the pump operating valves 9, 10. A counter 17 records the number of pumping strokes and thus the quantity of beer delivered. Alternatively. pump 3 may be connected to the dispensing device by a pneumatic control means.
