Title: Connection for an integrated circuit
IPC: H01L21/74
Filed: 1969-11-20
Abstract: 1,240,256. Semi-conductor device. ITT INDUSTRIES Inc. 20 Nov., 1969 [26 Nov., 1968], No. 56796/69. Heading H1K. A monolithic integrated circuit comprises a substrate 1 of one conductivity type, an epitaxial layer 4 of the opposite conductivity type, and a zone 5, within the layer 4, of the same conductivity type as the substrate, and in contact with the substrate. The method of construction includes diffusing into the substrate, except at contact area 2 to the zone, a heavily doped layer 3 of the opposite conductivity type, providing the epitaxial layer 4, and heating the device until the substrate impurity penetrates the layer 4 above the region 2 to a height suitable for contacting the subsequently diffused zone 5. The zone 5 may form a resistor, or the base of a transistor by a further diffusion of an emitter zone within the zone 5. Alternatively the resistor may be formed as a ring zone surrounding a core zone of the epitaxial layer, and be connected by an electrode to the core zone. The device is stated to reduce the number of surface contacts required, and to reduce overlaying connections. Antimony and boron may be used as dopants.

Compressed-air is introduced beneath the sheet, through a port 32, to press the sheet against a hold-down 50 which includes resistance heaters 54 for raising the temperature of the sheet to 520- 532‹ F. At this temperature the sheet is deformed into the die by compressed-air introduced through a passage 56, a pressure difference of 100 Lb./inch for 30 seconds being used. The sheet is then made rigid by cooling with vapour or, for a Zn-Al eutectoid, by heating between 532-600‹ F.
Patent GB-570171-A (GB)
Abstract: 570,171. Detergents. FAIRWEATHER, H. G. C. (Mathieson Alkali Works). Feb. 17, 1943, No. 2660. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 17, 1943] [Class 91] Detergent briquettes consist essentially of controlled proportions of sodium silicate, water, and either or both of trisodium phosphate and sodium carbonate. The briquettes may also contain a proportion of tetrasodium pyrophosphate, sodium tetraphosphate, or sodium hexametaphosphate. Instead of the latter ingredients or in addition thereto, a small proportion of a surface active agent may be added; sodium lauryl sulphate and sodium dodecyl benzene sulphonate are specified. The sodium silicate constituent ranges from metato ortho-silicate, i.e., where the Na2O : SiO2 ratio is from 1 to 2 ; or the alkalinity of the silicate constituent is below that required to produce the metasilicate, i.e., where the Na2 O : SiO2 ratio is less than 1. Three groups of briquette composition are particularised (1) where the above ratio is from 1 to 2 and containing all the four main constituents with or without tetra-sodium pyrophosphate, (2) with the same ratio for the silicate constituent and all the four main ingredients with sodium tetraphosphate or sodiumhexametaphosphate which results in the advantage of increasing the proportion of the trisodium phosphate with decrease of the soda ash content if desired, and (3) where the ratio for the silicate constituent is less than 1 when either the trisodium phosphate or the soda ash constituent may be entirely omitted. The materials other than the soda ash are heated in a steam-jacketed kettle and held at about 80‹-110‹C., the soda ash then being added to the fluid mass. The latter is finally drawn off into flexible moulds and cooled.

Title: Speech transmission system
IPC: G10L19/06
Filed: 1971-12-23
Abstract: 1356649 Speech transmission systems STANDARD TELEPHONES & CABLES Ltd 23 Dec 1971 59932/71 Heading H4R In a speech transmission system a self adaptive filter 1 is connected in a negative feed forward configuration in the speech path with the speech input signal for the filter also connected to the filter as the target signal, and the filter output being subtracted at 2 from the speech input signal to provide a residual signal output, from which the excitation function signal can be extracted. The excitation function signal and the multiplier coefficients of the adaptive filter are coded and transmitted to the receiver where the signals are decoded and fed to an excitation generator, to provide the input, and the multiplier adjustments of, an adaptive filter 9 connected in a positive feedback configuration, so that the original speech is available at the output of adder 10. In an alternative embodiment, Fig. 3, a decoder 24, 25, is incorporated in the transmitter with the adaptive filters 24, 23 of the decoders in the transmitter and the receiver both fed with an error signal derived by comparison of the output of filter 28, whose multipliers are directly coupled to the multipliers in the self adaptive filter 29, with the output of filter 24, so that the multipliers of filter 24, and hence filter 23, are continuously adjusted to be the same as those of filter 28 and hence filter 29, with the coder and decoders in the adjustment loop so that compensation is provided for quantizing errors &c. The excitation function signal and the multiplier coefficients, or error signal in the embodiment of Fig. 3, are slowly varying functions allowing low speed sampling for transmission. Since it is possible for the sampling to be of the same order as the resonance period of the input signal the sampling interval is made to vary in a pseudo random fashion. The adaptive filters are convention transversal filters with the self adaptive filter being described with respect to Fig. 2 (not shown).

Patent GB-2011223-A (GB)
Title: Synthesis arrangements for use in digital data transmission systems
IPC: H04J3/07
Filed: 1978-10-30
Abstract: In highspeed digital communication systems a number of tributary data streams SI may be multiplexed into a single main data stream having a higher aggregate data rate, pulse justification (pulse stuffing) time slots being provided, catering for the differences in phase and frequency between the individual tributary data and the main data stream and controlling remote oscillators in the demultiplexers. To reduce controlled oscillator realignment delays brought about by failure of signal SI a shift register storage arrangement SR is driven in parallel by the justification signals applied to the tributary data stream SI under normal operating conditions but does not have any output path. When the data stream SI fails the contents of the shift register are used to simulate the justification signals. Recirculation of the simulated justification signals also takes place while the data stream failure persists. The size of the simulated sequence (i.e. size of the shift register) determines the accuracy of the controlled oscillator and therefore the realignment delay. <IMAGE>
