Abstract: 1,157,123. Capacitors. CORNING GLASS WORKS. 13 Sept., 1966 [22 Sept., 1965], No. 40921/66. Heading H1M. Capacitors are manufactured by arranging interleaved conducting strips 18, 20 and vitreous glass ceramic strips 12, 14, 16 between thermal insulating layers 22, 24, compressing the arrangement by means of platens 26 while it is heated to the softening temperature of the glass ceramic but below the devitrifying temperature so as to fuse the glass ceramic layers together and embed the conducting layers therein, then heating to a temperature sufficient to devitrify the glass ceramic, cooling the assembly to room temperature after devitrification is complete, removing the pressure, thermal insulation and platens and severing individual capacitors from the fused stacks. Usually the method is applied to the manufacture of multilayer capacitors, the laminations being held together by means of a jig or by an adhesive such as biphenyl which will be removed by volatilization in subsequent operations. Layers 22, 24 may be mica and asbestos respectively, and platens 26 steel or refractory material. One glass ceramic composition comprises niobium pentoxide, lead oxide, barium oxide, strontium oxide, silica, alumina, boron trioxide and cuprous oxides, but other oxygen octahedra-type ferroelectric materials containing a glass-forming oxide may be used.

Title: Apparatus for defining continually the envelope of the maxima the minima and or modulation depth of a varying input signal
IPC: G01R29/06
Filed: 1972-09-18
Abstract: 1386332 Detecting maxima and minima R H HAMMERSCHLAG 18 Sept 1972 [20 Sept 1971] 43115/72 Heading G1U [Also in Division H3] Successive maxima (or minima) of an electric signal are gated out upon the occurrence of each following minima (or maxima). In a first embodiment, Fig. I, the output of a peak follower 1 is sampled and held in a store 3 each time a minima detector 6 produces an output, and immediately after a short delay # tv , the peak follower is reset. In a second embodiment Fig. 2 (not shown), the peak follower is replaced by a minimum follower (2) whose output is sampled and held every time a peak is detected. By using both these arrangements Fig. 3 (not shown), any function of the maximum and minimum values, such as modulation depth, which is defined as (max-min)/ (max+min), can be calculated. A detailed circuit which gates out successive minima when the following maximum occurs is described in Figs. 4 and 5. An input signal x is inverted by a unit U to give x which is followed by a peak-follower P. The occurrence of a maximum in x is detected by peak-following x with a unit P to give a signal al and by comparing this signal with the inverted input, namely x, in a comparator K1, which is arranged, with a unit A, to provide an output signal a5 which is "O" when the inputs to the comparator K1 sum to a negative value, and "1" when they sum to a positive value. Thus, the signal a5 has a positive going transition at the instant a maximum occurs in x (in fact, slightly later due to a small stabilizing feedback α around the comparator) which transition generates firstly a signal a8 causing the inverted output of the x peak follower (i.e. the minimum of x) to be stored in a unit S, and  secondly a delayed output a10 which resets the x peak follower to a reference level -r. A second comparator K2 detects the resetting of the x peak follower and resets the x peak follower. Three other detailed circuits Figs. 5 and 6, 7, 8, 9, 10 (not shown), are also described using generally  similar principles. The last of these circuits includes a "minimum selector", Fig. 11, which outputs, at e4, the smaller of two input signals e1, e2, and a circuit Fig. 12 which, on receipt of the inverted signal #x produces an output dl which  follows the maximum of the uninverted signal x, and also a two-level signal d5 which has a transition from negative to positive at the instant a . maximum value of x occurs.
