Title: Improvements in or relating to electrical prepayment meters
IPC: G07F15/00
Filed: 1927-01-07
Abstract: 288,688. A. E. G. Machinery & Apparatus Co., Ltd., and Smith, B. M. Jan. 7, 1927. Electricity, supplying by a a prepayment electricity meter the coin actuated mechanism closes the switch and energizes a spring which assists the meter, and the integrating portion of the meter is connected to the quantity mechanism by a train of wheels one of which is displaceable to allow the mechanism to be zeroized without further movement of the meter. Rotation of a knob 8, after prepayment, sets forward the planet wheel 12 of an epicyclic quantity mechanism, the planet wheel radius arm rotating a shait 17 through gearing 15, 16. The end of the shaft, 17 is formed as a part cylinder 23<1> which forms a stop for a lever 24 controlling the switch. The shaft 17 has a grooved pulley 18 connected to the framework by a spring 19 which is thus tensioned, and a slotted disc 20 co-operating with a pin 22 to limit the number of coins which can be inserted at one time. The return of the shaft 17 to its initial circuit breaking position normally takes place under the control of a meter shaft 3 through a universal coupling 4, 6, shaft 6, gearing 7, 26, 28, 29, the wheel 29 being rigid with one sun wheel 11 of the quantity mechanism which thereby returns the planet wheel 12. The wheel 28 is fixed to a shaft 27 which can slide through but rotates with the wheel 26. In order to zeroize the mechanism before the quantity prepaid has been consumed a key 33 is inserted through the casing into. engagement with a pin 34, and rotated to engage a knob 32 on the shaft 27 thereby displacing the shaft against a spring 30 and disengaging the wheel 28 from the wheel 29. The shaft 17 is then free to rotate to its initial position under the action of the spring 19.

[Class 89 (iii).] A machine for attaching pronged lock elements &c. to attache cases &c., is provided with two or more sets of attaching tools so that two or more elements can be attached simultaneously. The tools are readily adjustable and interchangeable, to provide for varying the positioning of the elements on the case and for attaching elements of varying sizes. Two tools l which hold lock elements with their prongs upwards are fixed to slides i which are adjustable along a table a. The slides are held in adjusted position by latches m engaging notches a<2> in the table, and by clamping screws n. Upper-tools i are similarly adjustable along a bar f which is attached to a plunger d slidable in a vertical guideway e. Each tool i comprises a sleeve i<4> which is a close fit on the bar f and carries pegs i<5>, and a plate i<6> which is carried by a yoke i<7> slidable on the sleeve i<4> against the action of a spring i<8>. In use, lock elements are placed in the tools l and the material of a case is placed over the upturned prongs of the elements and positioned by adjustable side and back gauges o<2>, r. The plunger d is then forced down by linkage from a treadle. The plate i<6> first causes the prongs to penetrate the material and then, the springs i<8> yielding, the pegs i<5> clinch the prongs. The tools can readily be adjusted by means of the notches a<2>, and can be removed endwise from the table and plunger bar, for replacement bv others of a different size. Specification 215,478, [Class 89 (iii), Nailing &c.], is referred to.

Abstract: 210,416. Dextrin Automat Ges. Jan. 27, 1923, [Convention date]. Cooling granular materials. - In apparatus for the conversion of powdered starch into dextrin, the starch is dried and the dextrin, in a finely-divided condition, is cooled and moistened while passing through similarly constructed shafts in the opposite direction to a drying and cooling or moistening gaseous medium, the passage of the material being restricted only by the action of the gaseous medium. As shown, the treatment is carried out in a shaft 1, Figs. 1, 2, and 3, the starch or dextrin being charged from a sifting-machine 1<4> into one of two hopper 3<1>, 3<2> from which it is raised by a conveyor 2<1> to a screw 4<1> which feeds the material into a duct 5 having at its lower end a distributor of known type for supplying the material to the shaft at a uniform rate. At the upper end of the shaft is a sieve 7 with which co-acts a rotary brush 8. After treatment in the shaft, the material is fed by a screw 9 to an elevator 2<2> which conveys it to a screw 4<2>, which rotates in the opposite direction to that of the screw 4<1>, and which discharges the material into a forked duct 6 having one arm 6<1> leading to one of the hoppers 3<1>, 3<2>, so that the material can be again passed through the slhaft, and the other 6<2> to a sack-filling device 10. For cooling the material, the shaft is supplied with upward currents of cold air, while for moistening purposes the shaft is supplied by an injector 12 with a, mixture of steam and cold air. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a ring at the top of the shaft to prevent material being carried away with the gaseous currents. This subjectmatter does not appear in the Specification as accepted.

Patent HU-T63279-A (HU)
Title: Echo-wiper and non-linear processor for said echo-wiper
Inventor: GENTER ROLAND
IPC: H04B3/20
Filed: 1991-07-30
Abstract: Residual echo from an echo canceler circuit is reduced by a variable attenuator that operates in response to a processing circuit which determines and adjusts an attenuation factor. The attenuation factor is determined by comparing relative levels of the send input signal, the receive input signal, and the error signal remaining after removal of an expected echo signal from the send input signal. The variable attenuator provides linear power attenuation of the error signal in order to reduce transmission of the residual echo signal and to eliminate the perception of coupling and decoupling of the telephone connection which occurs in known echo cancelers employing center clipping. A noise injection circuit provides a noise signal that is injected into the transmitted signal in inverse proportion to the attenuation of the error signal in order to provide a constant noise level in the transmitted signal as the error signal is variably attentuated.
