Abstract: 1354777 Measuring sheet resistance PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 June 1971 [6 June 1970] 18744/71 Heading G1U The method of measuring the surface resistivity (in ohms/square) of a thin (e.g. 5 micron) semiconductor layer 5, Fig. 5, on a second semiconductor layer 6 with which it forms a P-N rectifying junction, in which current is caused to flow from an electrode 1 to an electrode 4 and the potential across two intermediate electrodes 2, 3 is measured, is modified in that by the use of a switch S1 current is also caused to flow to the electrodes 2 and 3 in turn so that two additional potential measurements can be obtained, and all three measurements - together with measurements of the currents caused to flow - are utilized in a set of equations given in the Specification, to determine the required surface resistivity. The currents caused to flow have to be small (e.g. 0.5 ÁA) so that the rectifying junction is biased near the zero point of its current-voltage characteristic.

Title: Variable pressure hydraulic system
IPC: F15B11/05
Filed: 1973-04-19
Abstract: 1385852 Hydraulic control circuits DEERE & CO 19 April 1973 [20 April 1972] 19069/73 Heading F1P A variable displacement pump 10, whose output varies inversely with the pressure in a control chamber, is controlled by a pressure responsive valve 38, which connects the pump output to the control chamber through lines 42, 44 when the pump output reaches a bias level. A spring 48 tends to close the valve as does pressure in a pilot line 56 acting on a piston 52. A valve 58 normally connects the pilot line to sense the pressure applied by the pump to a ram 12 until the valve is closed by a member 64 pivoted about an axis 28 by the ram 12. In operation, if the valve 14 is closed the pump output will rise to the minimum pressure established by the spring 48. At this time valve 38 will open to connect the pump output through lines 42, 44 to the drive chamber of the pump 10. If the valve 14 is opened to operate the ram 12, pressure in the pilot line 56 acts on piston 52 so that the valve 38 closes. Fluid-pressure in the control chamber of the pump exhausts through a throttle 46 so that the pump output increases. If valve 14 is closed before valve 58 is closed by the arm 64, the pilot line 56 will be exhausted through a restriction 66. If the valve 58 is closed first, the line 56 will be exhausted through the line 62. Fig. 2, (not shown), illustrates a pump controlled by a piston 68 in a control chamber 70.

Patent GB-656231-A (GB)
Title: Dyeing of mixed fabrics
Filed: 1946-06-28
Abstract: Mixed fabrics containing both cellulosic and cellulose acetate fibres are dyed by immersing them in a dyebath or developing bath containing a cotton-substantive dyestuff or component and a water-soluble organic swelling agent for the cellulose acetate, whereby the affinity of the cellulose acetate for the dyestuff or component is stimulated and the affinity of the cellulose therefor is retarded, and the amount of swelling agent, the duration of immersion and the temperature of the bath are so chosen in relation to one another that the cellulose acetate fibres are dyed at least as deeply as the cellulose fibres.  Increase in the duration of immersion and increase in the temperature both tend to increase the depth of shade on each fibre but not at the same rate, so that for any predetermined proportion of swelling agent the relative depths of shade may be varied by altering the temperature or the duration of immersion. Examples are given in which a mixed fabric containing both viscose and acetate fibres is dyed with (1) the direct dye Pontamine Yellow CH No. 365 for 10 minutes at 100 DEG  F. in the presence of 60 per cent by volume of ethyl alcohol, (2) the reduced vat dye Sulfogene Brilliant Blue 3GCF No. 961 for 10 minutes at 160 DEG  F. in the presence of 8 g. per 1. of butyl alcohol, (3) Naphthol AS-SW for 10 minutes at 160 DEG  F. in the presence of 50 per cent by volume of ethyl alcohol and subsequently developed in Fast Red Salt ITR, (4) the vat dye Sulfanthrene Blue GDN and subsequently developed with ammonia and sodium hydrosulphite for 10 minutes at 160 DEG  F. in the presence of 20 per cent by volume of isopropyl alcohol, (5) Algosol Blue 04B and sodium nitrite for 10 minutes at 160 DEG  F. in the presence of 20 per cent by volume of isopropyl alcohol and then developed with sulphuric acid, and (6) Ciba Blue 2B Micro Powder No. 1184 and then developed for 10 minutes at 160 DEG  F. in sodium hydrosulphite and ammonia in the presence of 10 per cent by volume of ethyleneglycol monoethyl ether.  In (1) to (5) union dyeing is obtained and in (6) the acetate fibres are dyed a full shade while the viscose is only stained.  Specifications 592,858 and 599,055 are referred to.
