Abstract: 626,884. Prepayment mechanism for meters. SANDERS, E., and RANSOM, J. Oct. 18, 1946, No. 31006. [Class 27] The quantity differential of a prepayment gas meter comprises two bevel sunwheels 14 and 27, driven respectively by the coin and meter mechanisms, and a bevel planet wheel 26 for operating the supply valve held resiliently in engagement with the sun-wheels. In the mechanism shown, the planet wheel 26 revolves on a stub spindle 28 mounted on a spindle 29 connected to a valve-controlling scroll cam 33, and a compression spring 31 maintains it in mesh with the sun-wheels. The sunwheel 27 is driven by the meter through two worm gears 44 and 41, whilst the sunwheel 14 is connected to a quantity wheel 5 adapted to be engaged and rotated by a striker 7 on a rotary coin pocket 6; a coin inserted into the pocket couples it to a driver 50 on a hand shaft and engages the striker with the quantity wheel. The scroll cam 33 opens and closes the gas valve 3 by engagement with a pin 45 on a spring- loaded bell-crank 46 carrying the valve. When the mechanism is run back beyond zero credit and into debit, the pin 45 runs clear of the inner end of the scroll until finally contact is made between it and an inturned end of the scroll. This arrests the scroll and any further drive from the meter is taken by the quantity wheel running forwardly against a restraining pawl. Coin action, multiple-coin.-A two-speed gear is interposed between the sun-wheel 14 and quantity-wheel 5 so that the mechanism can be set for operation by either of two coins. A lever 16 which can be pivoted into either of two positions carries two pairs of pinions 18, 19 and 21, 22. In one position (shown) pinions 18, 19 interconnect wheels 9 and 12 fast respectively with the quantity wheel and sunwheel whilst, in the other position, the alternative pinions 21, 22 interconnect wheels 10 and 13 alternative to the wheels 9 and 12. Indicators.-A rotary drum indicator 38 showing credit and debit is driven through gearing 34, 37 from the valve cam 33.

Filed: 1973-07-02
Abstract: 1418346 Modulating light NIPPON ELECTRIC CO Ltd 2 July 1973 [30 June 1972] 31455/73 Heading H4F An optical isolator similar in principle to a microwave field displacement isolator comprises a light guide 2 formed in the material of a dielectric substrate 1, and a layer 3 of magnetic material disposed close to the guide and magnetized in a direction 4 perpendicular to the length of the guide, the arrangement being such that plane polarized light propagating in direction 5 is attenuated more than that travelling in the opposite direction. It is stated that layer 3 exhibits a relatively low refractive index to light in direction 5 whereby the optical and associated electric field intensity is greatest on the side of the guide remote from layer 3, Fig. 1b (not shown). Oppositely directed light sees a relatively highly refractive layer 3 and is therefore shifted towards layer 3, being absorbed by layer 3, or by a further layer adjacent the guide, for example a metallic resistance layer disposed over the layer 3, Fig. 4 (not shown). As particularly described, the light propagates in the fundamental TE mode, but a multiplex mode guide may be used. Layer 3 may be of FeF 3  (ferromagnetic) or a thin magnetic film may be used in conjunction with means for applying a magnetic field thereto. In addition to the rectangular form, the guide may be of the type having a radially varying refractive index. In other embodiments, the guide may be formed below the substrate surface, layer 3 being on the surface, or it may rise to the surface where layer 3 is disposed, or it may be disposed on the main surface of the substrate.
