Abstract: 393,720. Seat-operated taximeters. DEHN, F. B., 103, Kingsway, London.- (Checker Cab Manufacturing Corporation; Kalamazoo, Michigan, U.S.A.) March 18, 1932, No. 8145. [Class 106 (iii).] The control flag of a taximeter is depressed to operating position, on the sitting down of a passenger and the starting of the vehicle, through means actuated by a seat-operated switch. A passenger sitting down on the seat 2 makes the contacts 42 to complete the circuit 34 through the contacts 37 to energize the electromagnet 24, the spring-returned armature 25 of which pushes the pivoted pawl 10 into engagement with the worm 7 which is slidable on the shaft 6 but normally cannot rotate relatively thereto owing to the pin-and-slot connection 8, 9. The pawl 10 is held in engagement with the worm 7 through the spring-controlled detent 27 and dog 29 connected to the spring-returned armature of the unexcited electromagnet 31. On the vehicle starting the shaft 5 is driven to drive the shaft 6 and raise the worm 7 through the engaging pawl 10, a conical tappet 12 on the worm rotating the lever 13 about its pivot 14 to pull down the rod 15 which, through the spring-and-link system shown, rotates the shaft 22 and flag 4 to put the taximeter into operation. The worm 7 is raised until the pin 8 is disengaged from the slot 9, the switch 36 having broken the contacts 37 and made the contacts 38. On the passenger vacating the seat 2 the contacts 42 are broken and the contacts 41 made to make the circuit 35 through the contacts 38 to energize the electromagnet 31 to disengage the dog 29 from the keeper 30, the detent 27 then moving to the left owing to the return spring 26 for the now unexcited electromagnet 24 being stronger than the spring 28. A plurality of switches are provided in the seat, the switches being connected in parallel. The apparatus described above can be embodied in taximeters at present in use.

Abstract: 1449464 Distribution systems for natural gas EXXON RESEARCH & ENG CO 1 Feb 1974 [21 Feb 1973] 8443/73 Heading F4X A method of distributing natural gas comprises admixing with the natural gas a cheap diluent gas (e.g. flue gas, engine exhaust gas, or if cheaply available, nitrogen or hydrogen) at a pressure lower than the pipeline distributing pressure, and at one or more locations at or near the gas consumers. The said location(s) is preferably no further upstream from the consumers than the point where the pipeline pressure is reduced to the consumer network value. In Fig. 2, natural gas streams A, B, C at high pressure and of differing qualities (e.g. rich natural gas and lean natural gas) are mixed without dilution in a pipeline 15 from which the mixture is passed via pressure reducers 16, 17, 18 to medium pressure pipelines 19, 20, 21. Thereafter the gas flows via pressure reducers 23 to the local distribution network 22 for consumers. In the vicinity of, or incorporated in, the pressure reducers 23 are venturi mixers 24 through which the cheap diluent gas is introduced to the natural gas mixture. The amount of diluent gas so introduced is regulated to maintain a constant quality of gas to the consumer.
