Abstract: A method for transmitting data between subscribers to the public switched telephone network is specified in which in each case at least one telephone set, one data modem with a tone transmitter and a tone receiver and a data terminal are connected to the switched telephone network. The data modem is equipped with a circuit for detecting the ringing voltage with bypassing of the ringing pauses. To send out the data response tone and, if necessary for selecting the channel position, a distinction is made between "called" state and "calling" state after actuation of a data key in manual operation by the fact whether, when the loop current starts, a ringing voltage has been detected by the data modem or not.

IPC: H04B3/23
Filed: 1992-11-20
Abstract: In a digital echo canceller (EK) with residual-echo limiter (NLP), a threshold (Sa) is derived from the signal on the receiving path (EW), with which the level (PSWA) at the input of the residual-echo limiter (NLP) is compared. If the level (PSWA) is lower than the threshold (Sa), the path of the residual-echo limiter (NLP) is blocked. If not, it is opened. Since this threshold (Sa) is only derived for the echo passing via the adjacent hybrid, the residual-echo limiter (NLP) cannot respond to other echoes to the same receiving-path signal. Therefore, the rising total echo attenuation is measured from the beginning of a call and when a defined value is reached, the arrangement switches to a different threshold (Se) which is obtained by subtraction of the canceller attenuation (ACANC) from an artificial echo level (Py) which is derived from the digital filter (AFI) and a logarithmating unit (LG2). <IMAGE>

Date May 17, 1996An improved discharge valve comprises an upper housing, an upwardly movable main valve assembly within the housing and forming with the upper part thereof a variable volume upper chamber, a restricted passage between the upper chamber and the exterior thereof, an outlet leading down from the lower part of the housing, a seat for the main valve assembly at the entry to the outlet so that, in the lowered position of the main valve assembly, the outlet is blocked against ingress of fluid in which the device is immersed, and a pilot stem actuable remotely from the housing to put the upper chamber in free communication with the outlet. The arrangement being such that, once such free communication is established, fluid escapes the upper chamber and the change in relative pressures above and below the main valve assembly causes the latter to unseat thereby permitting flow of the immersing fluid into the outlet and its substantially complete discharge. The cessation of flow of the immersing fluid allows the main valve assembly to revert to its seated position with the pilot stem cutting off free communication, and air penetrates the upper chamber and on replenishment of immersing fluid, a net downward pressure is created on the main valve assembly to keep it seated. The pilot valve has a hollow stem communicating to atmosphere above the normal full set level of fluid in the cistern. The main valve assembly and the hollow stem define therebetween a hollow annulus.

Title: Method of treating polytetrafluoroethylene and to polytetrafluoroethylene so treated
IPC: B29C43/00
Filed: 1957-01-14
Abstract: A method of treating a quantity of polytetrafluoroethylene comprises applying thereto while it is within a temperature range defined by the second order transition temperature and a higher maximum temperature, superatmospheric pressure which is insufficient to produce cracks, in a pressure exerting device such as a mould until by visual inspection the quantity becomes wholly transparent but for an insufficient time to produce appreciable decomposition of the polytetrafluoroethylene, and cooling the quantity through the transition temperature, said maximum temperature being below that which produces appreciable decomposition of the polytetrafluoroethylene while it is within said temperature range. Shock-cooling may be employed, e.g. by transferring the quantity to a cold mould or immersing it in a cold fluid.  The quantity may be moulded and treated successively or simultaneously by employing pressure sufficient to mould the hot quantity to the desired shape. To facilitate removal of the quantity from the mould the latter may be faced with removable liners of conductive material, e.g. aluminium foil, and the liners and quantity removed as a unit and immersed in the cooling fluid. The polytetrafluoroethylene may contain additives which colour the quantity, and may then be subjected to conditions which are found to produce transparency in an equivalent pure quantity.  The process of the invention may be used to prepare diaphragm valve diaphragms having a greater flex life than those prepared by conventional methods.

Abstract: 563,222. Thermionic valve circuits. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. Jan. 29, 1943, No. 1538. [Class 40 (v)] The operation of a thermionic valve circuit supplied from a source of variable voltage is stabilized by the provision of a stabilizing valve to which the voltage variations are applied and from the anode-cathode circuit of which voltages are derived and applied to a grid so as to maintain the performance constant. The Figure shows an arrangement in which the variation in the high tension supply is applied to the grid of an auxiliary valve V0 after reduction through an appropriate number of neon discharge tubes N1 ... N3 which supplies the screen grid voltages to the operative valves V1, V2. In a modification, Fig. 4 (not shown), the auxiliary valve supplies the control grid voltages to the operative valves, the voltage being reduced by one or more neon discharge tubes. The use of neon discharge tubes may be dispensed with, but a less effective control is obtained and when the control grid bias is controlled the cathode biassing resistances associated with the valves may be variable to obtain an appropriate grid bias for the operative valves.
