Title: Production of jet fuel
IPC: C10G45/36
Filed: 1970-07-20
Abstract: 1312994 Hydrogenating and hydrocracking hydrocarbons ESSO RESEARCH & ENG CO 20 July 1970 [4 Aug 1969 (2)] 35025/70 Heading C5E Jet fuel is produced from an aromatics-containing feed, containing not more than 25 p.p.m. of sulphur by contacting with hydrogen at 200-780‹ F., 200-5000 p.s.i.g., and a space velocity of at least 0À5 v./v./hr. using a catalyst containing 0À05-30 wt. per cent of a Group VIII metal, e.g. Ni or Pt, and 0À1-2 wt. per cent fluoride composited with a refractory metal oxide, e.g. alumina, so as to convert aromatics to naphthenes. The catalyst suitably has a surface area of 250-600 sq. m./g. and its fluoride content can be maintained by the addition of HF or organic fluoride to the feed during processing. The jet fuel can be produced by (a) hydrotreating a feed, such as a virgin naphtha, highly aromatic hydrocracked feed or middle distillate suitably boiling within the range 320-550‹ F., or (b) hydrocracking feeds boiling in the range 430-850‹ F., to produce jet fuels and gasoline, suitable feeds are virgin gas oils, deasphalted oils containing 8-30 wt. per cent aromatics, catalytically cracked fractions containing 30- 70 wt. per cent aromatics, fractions from thermal, delayed and fluid cokers, shale oil, and solubilized coal. Fig. 1 (not shown) illustrates a process in which an aromatics containing feed is hydrofined at 600-850‹ F. and 800-5000 p.s.i.g. using a conventional catalyst, such as Co, Mo, Ni, W or a mixture of these on an inorganic oxide, charcoal or clay. The hydrofinate is scrubbed to remove hydrogen sulphide and then subjected to the low severity hydrocracking process of the invention and then fractionated. As shown in Fig. 2, a feed 38 is hydrofined using a conventional catalyst and then hydrocracked at 50 at 500-850‹ F. and 500-5000 p.s.i.g. using a conventional catalyst such as Pt, Pd, Ni or W on a crystalline zeolite, e.g. a platinum hydrogen faujasite. The hydrocrackate is distilled at 70 to produce a C 5 - 430‹ F. gasoline fraction and a heavier stream 54 which is passed to the low severity hydrocracking stage 60 of the invention. The hydrocracked effluent 61 is separated at 80 into a C 5 -320‹ F. gasoline fraction, a 320-550‹ F. jet fuel fraction and a recycle stream 62.

Abstract: 1,159,572. Unloading agricultural vehicles; endless conveyers; rotary elevators. JOSEF DECHENTREITER MASCHINENFABRIK G.m.b.H. 4 Aug., 1966 [5 Aug., 1965], No. 35058/66. Headings B8A and B8E. A crop feeding device which may operate in a fixed position or on a moving vehicle, comprises a floor on which the crop is deposited to be fed by an endless chain conveyer 7, 8 to tined feeding drums 27, 28, Fig. 1, by which the crop is fed to a slatted conveyer 41 by which it is fed to a blower for discharge from a tube 46. The drums 27, 28 rotate in the same direction and are inclined so that the foremost point of a tine path of one drum is spaced forward of a similar point of the next drum by less than the distance between the foremost and rearmost points of one of the drum's tine path and the top and bottom points of the tine paths are spaced from the top of the side wall 9 and the floor by a distance less than the highest and lowest points of a tine path. In a modification, Figs. 6, 8, the tined drums are replaced by conveyers 60-62, the inclination of which can be adjusted by a crank 81. Each conveyer comprises chains 69 with beams 70 forming supports for tines 71 and rods 72, the latter extending through blocks 73 pivotally mounted on the chains so that the tines are inclined away from their normal position perpendicular to the chain as they enter the crop to be fed. Plates 76 act as guides and strippers for the tines as they leave the crop. Controllable tines 87, Fig. 9, may be provided on the feed drums 27, 28 by providing supports 85 having tine supports 86, the arms 88 of which have rollers 89 located in a guide 90 so that the inclination of the tines is varied as they enter and leave the crop. The apparatus may be mounted on a vehicle and may be operated as it moves.

Title: Improvements in hydraulic power transmission mechanism
IPC: B60T11/22
Filed: 1932-12-10
Abstract: 411,537. Hydraulic transmission of power. HYDRAULIC BRAKE CO., 84, West Hancock Avenue, Detroit, Michigan, U.S.A. Dec. 10, 1932, No. 35066. Convention date, Dec. 12, 1931. [Class 69 (ii).] To facilitate the filling of a hydraulic transmission system, particularly for operating brakes, a non-return valve is adapted to be interposed between the master cylinder and the pipe lines to enable the cylinder to act temporarily as a pump. To maintain the system filled a device may also be provided associated with the master piston whereby an excess of liquid is introduced into the system at each application of the brakes, the excess returning to the reservoir at the completion of the return stroke of the master piston. The master cylinder 55, Fig. 5, is cast integrally with the removable bottom plate 53 of the reservoir 50 or it may be integral with an end plate thereof. The actuating arm 57 for the master piston 67 is adjustably clamped to a shaft 56 which extends through one side of the reservoir and carries an arm 58 connected to the pedal, the normal position of the arm being determined by a stop 81. The arm 57 bears on a steel plate 73 secured to the piston which may be positively coupled to the arm by a pin 76 engaging a hole in the plate 73. In a modification, the piston is returned by a spring disposed within the cylinder and is not coupled to the arm 57, the return movement being limited by a stop constructed of a length of wire 96, Fig. 8, bent to grip the cylinder 55<a> and having its ends 98, against which the piston abuts, passed through radial holes in the cylinder. The master piston 67 has a bore 70 in which is arranged a pair of cup-washers 71, 77 secured respectively to the plate 73 and to a rod 78 pivotally attached at 79 to the cylinder. When the piston is moved to apply the brakes, both its annular area and that of the cup-washer 71 is effective for forcing liquid from the cylinder 55 through the passages 71<1>, 72<1>, 73<1> to the brake operating cylinders, the liquid in the bore 70 flowing past the cup-washer 77. But during the return stroke, liquid is prevented by the cup-washer 77 from returning from the cylinder to the bore 70 which is re-filled by flow from the reservoir past the cup-washer 71. The excess of liquid, corresponding to the volume of the bore 70, thus introduced into the system normally returns to the reservoir through the port 83 when the piston has returned to normal position. To enable the cylinder and piston temporarily to act as a pump for initially filling the system, a non-return valve 90 carried by a screw rod 89 and normally disposed in the ineffective position shown, can by turning the rod be withdrawn to a position in which it lies between the passage 71<1> and the lateral ports 73' leading to the pipe lines so that liquid forced into the lines by operating the piston passes the valve and is prevented from returning thereby; the bleed valves on the brake cylinders are opened at this time.

Title: Safety devices for internal combustion engines operating with fuel injection
IPC: F02M63/02
Filed: 1960-10-13
Abstract: 904,910. Stopping. SULZER FRERES S.A. Oct. 13, 1960 [Nov. 17, 1959], No. 35153/60. Class 7(5) [Also in Group XXVIII] A safety stop device for an internal-combustion engine with fuel injection comprises at least one deformable blocking member having one portion held stationary and having another portion which can be moved by deformation of the blocking member into the path of a part which influences the fuel injection to prevent further movement of this part to stop the injection of fuel into the combustion chambers of the engine. As shown (Fig. 2) the blocking members are leaf springs 11. In normal operation of the fuel pump each blocking member occupies the position shown in chain dotted lines. The roller 4 with the part 5 can move freely and follow the movements imparted to them by the cam 3. Each part 5 actuates a piston which injects fuel into a combustion chamber of the engine. If in the event of a fault cable 12 is moved in the upward direction (Fig. 2) the load on the spring 14 is eased and the blocking member 11 tends to assume the position shownin full lines in Fig. 2. If the roller 4 is in a position below its top dead centre position the blocking member 11 continues to bear resiliently against the end of the pin 6 until the latter reaches its top dead centre position whereupon the blocking member 11 engages beneath it. The part 5 cannot now perform its return movement so injection of fuel into the engine ceases and the engine stops. Supports may be provided against which the. blocking members are supported in their blocking position. The supports may be provided with surfaces which are inclined to the direction of movement of the blocking members by an angle smaller than the angle of friction. As shown in Fig. 7 the blocking members are connected by a common connecting element 12 and are associated with a common tripping device 44. The tripping device may comprise a magnet 43 which is provided with an armature which acts against the force of a spring. By means of the coil 46 the device may be operated electrically in such a case the magnet 43 may be an electromagnet. Hydraulic or pneumatic tripping devices may be used. The safety stop devices need not act on the pistons of fuel injection pumps but may act on other parts which can prevent injection for example injection valves.

An extensible waistband for trousers, skirts, &c. is formed in at least two separate pieces 12, 13, Fig. 1, the end portion 15 of the piece 13 overlapping the adjacent end portion 16 of the piece 12 and passing through a slot 17, so that the extremities 18, 19 of the end portions extend in opposite directions around the inner side of the waistband between the waistband and lining. Strips of elastic material 21, 22 are stitched to the respective extremities 18, 19 at 23, 24, Fig. 2, and to the waistband at 25, 26 A male snap fastener element 44 secured to the end portion 15 may be engaged with either of the two female snap fastener elements 45, 46 attached to the end portion 16. The side seams 31 are left unstitched above the points 32, and the rearward extension 33 of the front part of the garment overlaps the extension 34 of the rear part so as to permit relative movement between the two pieces of the waistband.

Title: Method for the transfer of a liquefied gas from a first container to a second container
IPC: F17C5/04
Filed: 1973-07-24
Abstract: 1441623 Storage of liquefied gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 24 July 1973 35195/73 Heading F4P A method of transferring a liquefied gas from a first container 11 to a second container 16 comprises the steps of cooling a conduit 12, 15, 14 leading from and returning to, container 11 by circulating the liquefied gas of container 11 through the conduit by means of a pump 13, disconnecting coupling 15 in the conduit at a point 19 and then connecting it in position 15a, dashed lines, to the second container 16, and then transferring liquefied gas by means of the pump from the first vessel to the second vessel. The disconnectable coupling in the conduit can be replaced by a valve (Fig. 1, not shown). A solenoid 17 cuts off a valve in coupling 15 during transfer of the latter from the conduit to the second container 16. Cheek valve 18 automatically closes off the remainder of the conduit when the coupling is removed therefrom. A similar check valve 20 is connected to container 16. A by-pass line 21 continues circulation of liquefied gas in the conduit while the coupling 15 is being changed over.

Title: Improvements in and relating to magnetic amplifiers of the flux-reset type
Inventor: PETTIT RICHARD DAN
IPC: H03F9/06
Filed: 1957-11-13
Abstract: 894,185. Magnetic amplifiers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 10, 1958 [Nov. 13, 1957], No. 35411/57. Class 40 (9). In a two-stage full-wave magnetic amplifier secondary windings on a transformer 1 during any given half-cycle supply excitation for a load winding 9 or 9<SP>1</SP> of the first stage while supplying excitation for a control winding 7<SP>1</SP> or 7 of the second stage, current in both windings passing through a rectifier 3 common to both circuits. As shown in Fig. 7, the transformer 1 feeds four secondary windings 2a<SP>1</SP>, 2a<SP>11</SP>, 2b<SP>1</SP> and 2b<SP>11</SP>. During a half-cycle in which the windings 2a<SP>1</SP>, 2a<SP>11</SP>, are positive with respect to the centre tap CT, current flows over rectifier 5, resistor 4, and rectifier 3, to CT. Current also flows in reverse through rectifier 3 through control winding 71 and rectifier 8<SP>1</SP> and in parallel through load winding 9<SP>1</SP> and rectifier 10<SP>1</SP>. When load winding 9<SP>1</SP> becomes low impedance after an interval determined by control current in winding 11 of the first stage, control winding 7<SP>1</SP> of the second stage is short-circuited and current flows solely through rectifiers 3 and 10<SP>1</SP> and load winding 9<SP>1</SP>. Since the saturation time of winding 9<SP>1</SP> governs the reset time of winding 7<SP>1</SP> the input to the first stage governs the output to load L in the following halfcycle. During a half-cycle in which windings 2b<SP>1</SP>, 2b<SP>11</SP>, are positive with respect to CT winding 7 is reset for as long as it takes winding 9 to saturate, rectifier 3 being opened to reverse conduction by current over rectifier 6. Secondary windings 2a<SP>11</SP> and 2b<SP>11</SP> may be omitted, rectifiers 5 and 6 being connected in common with rectifiers 8, 10 and 8<SP>1</SP>, 10<SP>1</SP>, provided windings 9 and 9<SP>1</SP> are given a higher current rating. To block back coupling between the windings 9 and 9<SP>1</SP> through control winding 11 when the control source has a low impedance, a bias voltage is connected into the idle half of the inter-stage coupling during each halfcycle. As shown in Fig. 8, this is achieved by use of two rectifiers 31 and 3<SP>11</SP> with alternating off-centre taps CT1 and CT2. Alternatively, a rectified bias voltage may be generated across a resistor in series with rectifier 3 of Fig. 7 or separate such bias resistors may be included in series with each rectifier 10 and 10<SP>1</SP> (see Figs. 10 and 11, not shown). To provide an improved resetting current waveform the resistor 4 is preferably given some inductance.

Abstract: 507,914. Turning. - gear. BOSCH GES., R. Dec. 22, 1937, No. 35453. Convention date, Dec. 22, 1936. [Class 7 (v)] In an engine starter in which a pinion b is longitudinally displaceable on the starter shaft a under the control of a manually operable lover n and a spring s, displacement of the lever n moves an intermediate member d into an operative position, where it is held relatively to the lever, and at the same time compresses the spring s; on release of the lever, the displacement of the member d and the pinion as a unit to bring the pinion into engagement with the engine is effected by the compressed spring alone. As shown, the lever n engages a coupling element f connected by a pin-and-slot to the member d, which is pivoted upon an annular member c carried by the pinion. A centrifugal weight e is pivoted on the axis of the member d and the parts are normally held by springs g, s, k in the positions shown. In operation, movement of the lever n as indicated by the arrow displaces the element f to compress the spring s, and the member d is rocked so that its lower end moves across the vertical plane of the pivot. On releasing the lever n, the element f and the pinion are moved axially by the spring s to mesh the pinion with an engine member, the members f, d being retained in their relative position by the spring g. A part t of the pinion operates the starter switch q. When the engine starts, the member d is rocked into its initial position by the centrifugal weight e, thus drawing the pinion out of mesh.

Abstract: 1515846 Fuel injection pumps CAV Ltd 25 July 1975 [13 Aug 1974] 35578/74 Heading F1A In a rotary distributer type fuel injection pumping apparatus wherein, during the filling strokes of the pumping plungers 12, the pumping chamber 11  is connected via a port 21 to receive fuel displaced from one end of a bore 27 by a fuel actuated shuttle 28, the quantity of fuel displaced is determined by an electrically controlled valve 31 which governs the starting point of the shuttle by controlling the escape of actuating fuel during the shuttle's return strokes. The shuttle 28 is driven towards the port 21 by fuel from a feedpump 25, the fuel being directed by a rotary valve 23 to the side of the shuttle 28 remote from the port 21 via a passage 29 and a non-return valve 30. At this time inlet passages 20 in a rotary member 10 connect the port 21 to a passage 18 connected to the pumping chamber 11. After filling of the chamber 11 is completed, inward movement of the plungers 12 delivers fuel through a passage 16, 14 to whichever of delivery outlets 15 is in communication therewith. During delivery the shuttle 28 is returned by fuel from the feedpump 25 supplied to the cylinder 27 via a port 21a now connected by a passage 22 in the member 10 to the port 21. Fuel behind the shuttle 28 escapes through the electrically controlled valve 31 and a rotary valve 24. When a coil 39 senses that the shuttle 28 has completed its desired displacement, an electrical control circuit 38 energizes or de-energizes, Fig. 3 (not shown), an electromagnet or a stack of Piezo-electric crystals 35 to close the valve 31 and thus stop the shuttle 28. The crystals 35 act through a column of liquid and a piston 34 on the valve element 32 of the valve 31, the element 32 being loaded to the open or closed position by a spring 33 and feedpump pressure.
