Title: Method of producing liquid hydrocarbons from a subsurface formation
Inventor: DAALEN FRANCOIS VAN
IPC: C09K8/592
Filed: 1966-04-07
Abstract: 1,112,956. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 7 April, 1966, No. 15597/66. Heading E1F. Liquid hydrocarbons are produced from a subteranean permeable formation by supplying to the formation a first fluid having an S.G. lower than that of the hydrocarbons and by causing a second fluid having an S.G. higher than that of the hydrocarbons to flow through the formation, the first fluid flowing through the upper part of the formation and reducing the viscosity of the hydrocarbons in that part, the second fluid flowing through the lower part of the formation to displace the hydrocarbons upwardly without effecting their viscosity, and producing the hydrocarbons from the upper part only. The first fluid may be a hot fluid, a fluid which reacts with the hydrocarbons to generate heat, or a solvent of the hydrocarbons, examples of the fluid being propane, butane, steam or air. The preferred second fluid is water which may be artificial water, or bottom water or a mixture of artificial and bottom water. The two fluids may be injected simultaneously or alternately, continuously or wells and the hydrocarbons produced from a intermittently through a single well or separate well spaced from the injection well for the first fluid. In a modification the simultaneous injection of the second fluid and the production of the hydrocarbons follow the injection of the first fluid. The production takes place through the injection well of the first fluid and the injection of the second fluid may take place through the same well or through well located at a distance therefrom.

Title: Improvements relating to automatic electric switches
IPC: H01H83/12
Filed: 1922-06-20
Abstract: 208,731. Cox, F. B. June 20, 1922.. Automatic circuitbreakers. - Loose-handle automatic circuit-breakers have a rectilinearlymoving contact-carrying rod A with springs a<1>, tending to move it to the " off " position. In addition to these springs quick make and break mechanism of the type described in Specifications 23162/11 and 23107/14 may be provided. The operating mechanism consists of a lever C pivoted at c<2> and connected by links D<2>, D' pivoted together at d to one arm b<3> of a bell-crank lever pivoted at b<2>. The other arm B is connected by links b<1> to a block a<2> sliding on the rod A and carrying a pin a<3> which moves on a slot a<4>. In closing the switch the arm C is rotated to the dotted position shown in Fig. 1, allowing projections d<2>, d, to engage so that the links D<2>, D<1> act as a strut between the arm c' of the lever C and the arms b<3>. The pin a<3> is thereby moved to the bottom of the slot a', taking up the lost motion, after which the switch closes. In its final position the arms C and D<2> form an overset toggle, the switch springs holding the arm C against a stop c<3>, Fig. 3. Pivoted at e<1> to the rod A is a lever E with an enlarged head e<5> and carrying at e<2> the core f<1> of a no-volt magnet F. A spring e<3> is connected between the point e<2> and a fixed point e<4> so arranged that during the closing motion of the rod A the line of action of the spring crosses the axis of the rod E, the switch contacts being arranged to engage slightly before this takes place so that when the switch is closed (Fig. 3) the rod E is maintained by the electromagnet F against the action of the spring e'. When the electromagnetic force falls sufficiently due to diminution or failure of the supply voltage the rod E is moved to strike the rod D<2>, collapsing the strut D<2>, D', and allowing the switch to be opened by the springs a<1>. Alternatively the no-volt armature f<4> may be attached to the end of the rod E as shown in the dotted portion of Fig. 1. The switch may be opened mechanically by backward movement of the handle C. Alternatively, as shown in Fig. 5, the arm c<1> is separated from the handle C which has a projection c<6> for engaging the end c of this arm. A spring c<4> tends to pull off the arm c<1>, but this is normally overcome by the force produced by the springs a<1> on the toggle c<1>, D<2>. In a further alternative the arm C is retained by a pivoted catch connected by a link to a spring-controlled bell-crank lever which is depressed by the arm B as the switch is closed. The handle may be moved laterally to disengage this catch. Adjustable overload electromagnets may be arranged to short-circuit the coil F so as to trip the switch on a predetermined overload.

Filed: 1975-04-17
Abstract: 1496957 Toy vehicles J H LEMELSON 17 April 1975 15902/75 Heading A6S A wheeled toy vehicle is powered by a thrust propeller rotated by a rubber band motor. In one form, a toy vehicle 10, Fig. 1 has a lightweight body 12 of foamed plastics supporting front and rear wheels 17, 19. A thrust propeller 25 at the rear of the vehicle is driven by a rubber band motor 28. As shown, the body 12 has an open bottom 13'. The bottom 13' of the body 12 may instead be closed, to represent a land-sea vehicle or boat driven across the water on which it floats by the thrust propeller. In another form a rubber band motor 54, Fig. 3, is mounted within a pod 44 on top of a toy vehicle. In a third form the body of a toy vehicle 80, Fig. 5, consists of two mutually perpendicular plates 83, 91. An arrangement for winding a rubber motor 28, Fig. 4 in such a toy vehicle consists of a hand-held electric motor 79 and clutch shaft 81 inserted into a driven clutch 74 fast on a winding shaft 72 while the end 78 of the motor housing engages and forces leftwards a non-rotary detent plate 69A in the toy body 64. Holes 69H in the detent plate 69A are thus disengaged from detent dogs 75 on the driven clutch 74, which is freed for rotation by the electric motor 79. On completion of winding, the motor 79, &c. is withdrawn and a compression spring 70 slides the detent plate 69A rightwards to reengage its holes 69H with the detent dogs 75. The driven clutch 74 is thus held from rotating and the rubber 28 retained in its wound-up condition.

Filed: 1925-06-22
Abstract: 235,918. British Thomson-Houston Co., Ltd., (Assignees of Compagnie Fran- þaise pour l'Exploitation des ProcÚdÚs Thomson-Houston). June 20, 1924, [Convention date]. Alternating-current induction machines.-In a system in which an induction motor is cascaded with a series-characteristics commutator motor, the slip of the induction motor is caused to increase with load by causing the commutator motor to drive another machine, the speed of which increases as the torque of the commutator motor increases. By these means, the speed of the main motor is made to fall more and more quickly with increase of load without the necessity of constructing the commutator machine of large size in order to obtain low saturation. In the form shown in Fig. 1, a series commutator machine B derives slip energy from the induction motor A under regulation, and it is mechanically coupled with an induction generator C which transfers the slip energy back to the mains supplying the motor A. A resistance R in the secondary circuit of the machine C causes the speed of the group B-C to increase with increase of load on the motor A. It is shown in the Specification that this results in the slip of the motor A increasing more and more as its load increases. The resistance R may be embodied in the rotor of the machine C, for instance as a squirrel-cage winding, or it may be replaced by a small series commutator machine connected to the rings of the machine C. Alternatively, the machine C may be replaced by a continuous-current generator with a counter-compounding series coil.

Abstract: 959,924. Tamperproof cartons. AMERICAN CAN CO. May 1, 1962 [Sept. 12, 1961], No. 16599/62. Heading B8P.  Opposite end flaps 56, 58 of a carton have projections 35, 45 which, when the flaps are folded down and interlocked, take into corresponding cut-out portions of the other flap and engage under angled cuts 38, 43 so that the carton cannot be opened without mutilation of the locking elements. The carton is made from an integral blank A, Fig. 1, cut from a continuous web of sheet material, successive blanks A, A<SP>1</SP> being cut to dovetail together and thus eliminate waste. When the blank is erected panel 50 is folded about score line 10 to lie over panel 51, glue being applied along the edge of panel 50 and main panel 53 is folded about score line 12 so that panel 54 is adhered to panel 50. The partially erected carton is squared, flaps 55, 56, 59 folded in, and the end flaps 56, 58 simultaneously folded in about score lines 15, 17. As the outer edges of these panels approach each other the male elements 35, 45, 35 are bent slightly inwardly and pass under the opposed female elements and become locked, Fig. 3, by the engagement of the elements with the angled cuts 38, 43. This locking prevents lateral shifting of the end panels, and renders the carton tamperproof. In a further embodiment two full narrow side panels give uninterrupted printing surfaces.
