Title: Methods of manufacturing semiconductor bodies
IPC: H01L21/205
Filed: 1972-01-31
Abstract: 1420065 Semi-conductor devices MULLARD Ltd 29 Nov 1972 [31 Jan 1972] 4513/72 Addition to 1307546 Heading H1K The invention is concerned with ensuring that a boundary 6 between a lightly doped surface layer of a semi-conductor body and the more heavily doped bulk of the body is at a constant depth from the surface 5 despite irregularities in the thickness of an epitaxial layer 2 containing the lightly doped surface layer and deposited on a heavily doped substrate 1. This is achieved by bombarding the entire surface 5 with ions, such as protons or ions of He or Na, which produce crystal damage in the vicinity of the boundary 3 between the substrate 1 and layer 2, while maintaining the body, if necessary by the application of external heat, at an elevated temperature such that enhanced diffusion of substrate impurities occurs into the damaged region of the layer 2. The constant depth of the resulting boundary 6 follows from the Gaussian profile of radiation damage about the mean penetration depth of the bombarding radiation. Examples are given employing Ag, As, Sb and P in various combinations as dopants in Si.

Title: Control systems or arrangements for providing a control in response to changes of voltage or current ratio
IPC: G05F7/00
Filed: 1934-07-25
Abstract: 438,839. Automatic volume control. JONES, C. E. P., 159, Dollis Hill Avenue, Cricklewood, London. July 25, 1934, No. 4659 /35. Divided application. [Class 40 (iv)] [See also Group XL] The input and output voltages of an alternating-current transmission network, such as a telephonic amplifying system, are rectified and applied to logarithmic units, and the outputs from these units are combined differentially to provide a direct current control voltage or magnetic flux proportional to the output /input ratio, which may be used to control the attenuation or gain of a device associated with the network whereby the overall attenuation or gain is maintained approximately constant. As shown in Fig. 2, an incoming line A is connected to an outgoing line B through an attenuator 2 and an amplifier valve 1. The amplifier input voltages are applied through a series resistance 14 to a rectifier 12, and the D.C. voltage appearing across the condenser 13 is applied through a device 4, such as is described in Specification 371,443, [Group XXXVI], to a resistance 11 giving a voltage across this resistance proportional to the logarithm of the voltage across the condenser 13. The output voltage is similarly applied through a rectifier 12 and logarithmic unit 6 to a second resistance 11. The voltages across the resistances 11 are differentially combined in a circuit 3 and are applied to an attenuator network 2 similar to those described in Specification 413,383 and comprising series and shunt rectifiers 8 and resistances 9, causing the attenuation of the network in decibels to change linearly with the voltage applied at 3. The voltages applied to the rectifier 12 may be taken from the input, instead of the output, of the attenuator 2. In a modification shown in Fig. 4, the attenuator is omitted, and the differential voltage across the resistance 16 is used to vary the grid bias of the amplifying-valve 15 which is of the variable-mu type. Frequency correcting or equalizer networks may be provided.

Title: Manufacture of malt beverage
IPC: C12C7/20
Filed: 1963-02-05
Abstract: In producing a wort suitable for use in the preparation of an alcoholic malt beverage, rice or rice bran is milled with miller, starch, starch syrup and pure plant protein are added to the milled mixture, the entire mixture is boiled to form a paste, a minor amount of malt is added to the paste, the malted paste is warmed to saccharify the starch, a proteolytic enzyme (pepsin or trypsin) is subsequently added, the mass is heated to hydrolyse the protein and is then filtered to obtain the wort.  Hops and an amino acid, e.g. L-tyrosin or L-phenylalanine are added to the wort prior to its fermentation utilizing Saccharomyces cerevisiae, Saccharomyces carlsbergensis or other bottom-fermenting beer yeast. In an example 10 g. of rice and 10 g. millet are milled together, then mixed with 10 g. pure gluten, 30 g. starch, 100 g. starch syrup and 1200 ml. water, and the combined mixture is boiled to form a paste.  This paste is admixed with 28 g. malt powder and after maintaining this mixture at a temperature of 37  DEG C. for an hour, 0.02 g. protease obtained by culturing Streptomyces griseus is added. The resultant mixture is thoroughly stirred while the temperature is slowly raised to 50  DEG C., this temperature then being held for a period of one hour whereby the protein is hydrolysed.  The temperature is raised to between 55  DEG C. and 85  DEG C. for three hours to complete the saccharification. Filtration yields 1 litre of clear wort.  After the addition to this wort of 2.3 g. hops and 0.4 g. amino acid, the resulting liquor is boiled for about one and a half hours and then cooled. Fermentation is carried out employing 100 ml. of a cultured bottom-fermenting beer yeast in a closed vessel at a temperature of 8 DEG C. to 14  DEG C. for 10 days and further at between 3  DEG C. and 5  DEG C. for 30 days. Finally the fermented liquid is cooled at -1 DEG C. and filtered under pressure.

Title: Improvements in or relating to the manufacture of artificial threads
IPC: D01F2/30
Filed: 1932-02-17
Abstract: Cellulose acetate artificial threads are made by downward dry spinning in a diluted evaporative atmosphere, the usual spinning solutions being preheated before issuing from the dies at such a temperature that their viscosity does not exceed 100 C.G.S. units, and the filaments being only subjected during the spinning operations to a stretching not exceeding the ratio 2.  The threads produced, which may be used for the manufacture of artificial crepe fabrics, have an elongation at breaking greater than 30 per cent, and a breaking load similar to that of the usual cellulose acetate threads. According to an example, a collodion prepared from cellulose acetate and a solvent consisting of acetone and ethyl alcohol is preheated to 67 DEG  C., extruded through a die comprising 18 orifices of ,06 mm. diameter, and collected in the form of a thread of 100 deniers.  The spinning cell may be heated to 85 DEG  C., air being circulated at a rate of 3,500 litres per hour, and a spinning speed of 100 metres per minute employed.  In the production of crepe fabrics from the threads obtained, swelling without peptization may be reduced to a minimum, or in some cases dispensed with, particularly in the case of fabrics with slack weaves, for fabrics of the type crepe georgette and crepe Roman, and for fabrics where the strongly-twisted acetate threads are used to obtain special decorative effects.  The threads can also be used for the manufacture of artificial horsehair or straws. Specifications 238,842, 248,696, 300,672, [all in Class 2 (ii), Cellulose &c.], and 335,020, [Class 42 (i), Fabrics, Finishing, &c.], are referred to.
