Abstract: 539,375. Electric resistance heaters. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 11, 1940, No. 15160. Convention date, Oct. 11, 1939. [Class 39 (iii)] In an electric heating element of the sheathed wire type as described in Specifications 144,767, [Class 39 (iii)], 356.586, [Group XXXVI], and 473,876, an insulating support 16 for a helical resistance 11 is formed of two sections 16a, 16b, each with an inwardly extending rib 18 which engages between the turns of the helix. External ribs 17 in contact with the sheath 12 hold the sections in assembled position. The sections are applied to the resistance after the terminals have been secured, as the resistance is being fed into the sheath from left to right. The sheath is marked at points 23a and is then reduced at those points to prevent movement of the supports 16 as the magnesia filling is fed in with the element in a vertical position. A washer 19 closes the sheath at the lower end, and a pin 20 positions the terminal 15 at the upper end, a washer 20 being finally added and secured by deforming the end of the sheath over it. The unit is then elongated and its diameter reduced to compact the insulation, by swaging, rolling, or drawing, to a diameter equal to or less than the parts 23a. In this operation, the supports 16, which may be of lava, are crushed. Lava sleeves 25 for the initial support of the terminals 14, 15 may also be provided. In a modification, Fig. 10, the supports may have part-circumferential flanges 30 instead of longitudinal ribs 17.

Abstract: 1472901 Deaf aids; gain control J L HOLMES 9 April 1974 [12 April 1973] 15648/74 Headings H4J and H4R  Amplification apparatus for providing compensatory amplification for an aurally handicapped person has a signal path from input 11 (Fig. 1) to output (19) the path being divided to pass in parallel through a circuit 15, 16 of frequency selective characteristic and a circuit 14 of substantially non-frequency selective characteristic and recombined in a summation circuit. An automatic gain control circuit 60 is provided to control the amplitude of the output of the frequency selective circuit 15, 16. The amplitude of the output of the non-frequency selective circuit 14 is separately adjustable. The input 11 may be a miniature ceramic microphone including a F.E.T. whose output is applied to a broadband A.G.C. transistor (12) Fig. 2 (not shown) and then to a preamplifier 13 in the form of an operational amplifier. The output of preamplifier 13 is fed to a potentiometer gain control 14 and through the filter A.G.C. 15 to the input of a filter driver (16A) Fig. 2 (not shown) in the form of an operational amplifier to a filter network 16. An operational amplifier is employed as an amplifier 17. The output of the amplifier 17 is connected to a potentiometer volume control 18 and receiver 19. The output of amplifier 17 is also connected to the input of an A.G.C. potentiometer (60A) whose output is connected to the input of an operational amplifier A.G.C. detector (60B) the two of which serve as the A.G.C. detector 60. Receiver 19 is preferably of magnetic type having a diaphragm and, if desired the receiver 19 may be placed entirely within the ear channel. The preamplifier 13 may precede the broadband A.G.C. 12. The filter A.G.C. 15 and filter 16 may be interchanged. The negative input of operational amplifier 17 may be used to sum the signals from flat gain control 14 and filter network 16 or the output from flat gain control 14 may be connected to the positive (non- inverting) input and the output from the filter network 16 connected to the negative (inverting) input of amplifier 17 thereby allowing a smoother frequency response (Fig 5 not shown). The filter 16 may be a 6-pole high pass filter including three operational amplifiers 25, 26 and 27 in an active filter configuration. A suitable filter has its break frequency capable of being placed anywhere from 200 Hz to 10,000 Hz. Adjustable resistors determine the break frequency and the Q of each 2-pole section (Fig. 3 not shown). A somewhat similar 6-pole band pass filter is also described (Fig. 4 not shown). The filters may have a gain of from 0dB to 40dB, typically 30dB. In alternative arrangements (not shown), the filter network is of 2 pole or greater and of high pass or bandpass configuration or combinations of both.
