Filed: 1971-07-02
Abstract: 1361226 Investigating a liquid sample YANAGIMOTO SEISAKUSHO CO Ltd 2 July 1971 [4 July 1970] 31240/71 Heading G1A In a photo-meter for absorption analysis, light from a source 1 is passed as shown through a sample cell 2 and then split by two beamsplitters 7 and 8 into three beams, each beam path containing monochromatic means 9a, 9b or 9c and a photo-electric device 11a, 11b or 11c. The monochromatic means pass different wavelengths corresponding to the beginning, ending and maximum wavelengths of the absorption spectrum of a substance of interest in the sample being investigated.  The outputs from each photo-electric means is fed to a logarithmic transducer and the resulting signals are fed to a mean value computer. Four adjustable diaphragms 5, 10a, 10b and 10c are set so that the incident light intensity I 0 # 2  on the sample corresponding to the maximum wavelength is equal to mean incident light intensity I# a  of the beginning and ending wavelengths. The absorption degree (i.e. the concentration) may be expressed as follows: where As = Absorption in degree I# a  = Mean intensity of transmitted light I# 2  = Intensity of transmitted light of the maximum wavelength. The description discloses a method of calibrating an ammeter Ad on the basis of this formula with the aid of a switch S to indicate directly the degree of absorption.

Title: Method of and apparatus for testing lip seals
IPC: G01L5/00
Filed: 1962-08-15
Abstract: 940,866. Testing shaft seals. GENERAL MOTORS CORPORATION. Aug. 15, 1962 [Aug. 25, 1961], No. 31295/62. Heading F2B. The radial force characteristic of a lip seal 36 is determined by placing the seal around a test shaft 48, locally radially displacing the lip 54 by a known force and measuring the rate of flow of air between the seal and the shaft as a result of the displacement. The shaft 48 is secured by a bolt 50 to a hollow spindle 43 rotatably mounted in a housing 10 having an end plate 32 in which the seal 36 is held by a clamp 38 connected to a lever 40 operable by a pneumatic cylinder 42. A plug 58, having a curved outer surface 66 of the same radius as that of the shaft 48, is slidably mounted in a transverse bore 60 in the shaft; the movement of the plug being limited by a pin 62. Compressed air from a source 74 is supplied to a chamber 52 within the shaft 48 via the interior 68 of the spindle 43, a conduit 72, gauge 78 and regulator 76 and to a space 80 beneath the seal 36 through a conduit 84, a flow meter 86, gauge 90 and regulator 92. A garter spring 56 surrounds the lip 54. In operation, after the seal has been located in engagement with the test shaft and held by actuation of the clamp 38, air at a predetermined pressure is supplied to the chamber 52 to move the plug 58 outwardly and thereby radially displace the lip 54 by a corresponding force and air which is supplied to the chamber 80 at a relatively low pressure escapes at a rate according to the displacement of the lip, the rate being measured by the meter 86. The shaft 48 and spindle 43 are then moved angularly in steps by a hand wheel 94 and the rate of air flow measured by the meber 86 noted at each point around the seal. The process is then repeated supplying air at a second predetermined pressure to the chamber 52. The seals are accepted if the maximum rate of air flow does not exceed a given value with one predetermined pressure and the minimum rate of air flow is not less than another given value with the second predetermined pressure.

Title: Improvements in or relating to solid state circuits
Inventor: SANDBANK CARL PETER
IPC: H01L27/07
Filed: 1963-08-08
Abstract: 1,023,591. Solid circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 8, 1963, No. 31322/63. Heading H1K. A solid state circuit including a transistor and PN diode is made by diffusing a first impurity of one conductivity type into one surface of a wafer of the opposite conductivity to form the base zone of the transistor and one region of the diode and subsequently diffusing impurity of said opposite type into these regions to form the transistor emitter zone and the other region of the diode. The one region of the diode is subsequently shortcircuited to the bulk of the wafer, constituting the transistor collector, bya metal layer alloyed to the wafer surface. A NOR circuit of this type shown at an intermediate stage of manufacture, Figs. 8 and 9 (not shown) is made as follows: An apertured oxide film is formed on an N-type silicon layer epitaxially deposited on an N + silicon substrate by oxidation and photoresist and etching technique, and acceptor impurity diffused through the apertures in an oxidizing atmosphere to form P- zones 71, 73, 74, 76 (Fig. 7). 73 is a transistor base, 76 one region of several diodes, 71 an isolating region and 74 a resistive track. Donor impurity is diffused through a second similarly formed mask to form zones 72, 75, 77, 78 overlying the P-zones and zone 79 alongside P-zone 76. Of these 72 and 77 constitute resistors, 75 the transistor emitter and 78 the other regions of the diodes. The wafer is again masked, aluminium evaporated over the entire masked surface to contact the various zones at 80-89 (Fig. 8, not shown) and residual aluminium removed by etching through a mask. Contact 86 provides the short-circuiting connection. Finally aluminium interconnections are evaporated on (Fig. 10, not shown) through a mask to complete the circuit diagrammed in Fig. 1 (also not shown). A graded chromiumgold film as described in Specification 1,023,531 may be used instead of aluminium for the contacts. In addition, germanium may be used in place of silicon, in which case the masking layers are formed of vapour-deposited silicon monoxide.

Title: Improvements relating to remote control electric receivers for synchronous selector systems
IPC: H02J13/00
Filed: 1950-12-28
Abstract: 681,959. Electric selective signalling. LANDIS & GYR AKT.-GES. Dec. 28, 1950 [Jan. 6, 1950], No. 31456/50. Class 40 (i). In a selective signalling system using synchronous selectors at the transmitter and receiver, a magnetic amplifier is used in the receiver between a resonant circuit responsive to the signal pulses and the selector. As shown, a seriesresonant circuit 3, 4 responds to audio frequency control impulses sent over power lines 1, 2. The control voltage thereby developed across the inductance 4 energizes through a rectifier. 5 the D.C. control winding 6 of a magnetic amplifier 7. The A.C. windings 11, 12 of the amplifier are series connected with a rectifier bridge 13 and a synchronous motor 14 across the power lines 1, 2, but normally the impedance of the windings 11, 12, is so high that the current flow is insufficient to drive the motor. A control impulse saturates the outer limbs 9, 10 of the amplifier magnetic core 8. The consequential increased current flow in the A.C. windings 11, 12, enhanced by a regenerative winding 17 fed from the rectifier 13, starts the motor 14, which switches over a contact 15 to provide a self locking circuit, so that the motor drives a selector'switch 19 through one revolution when the contacts 15 again reverse. Further control impulses sent at the appropriate times during the selector movement, actuate solenoids such as 21, 22, over the selector wiper, to control local circuits e.g. as at 23. A condenser 24 effects series compensation for the inductance of the windings 11, 12. The synchronous motor may, alternatively, be switched in by a relay energized by the control impulse, and a mechanical selector e.g. as described in Specifications 633,195 and 642,479, [both in Group XXXVII], may be used in lieu of the electric selector..

Filed: 1929-10-16
Abstract: 337,940. Buchi, A. Oct. 26, 1928, [Convention date]. Drawings to Specification. Motor power plant.-In a double-acting internal-combustion engine the inner and outer ends of the power cylinders exhaust to separate turbines or to separate chambers of the same turbine; a compressor driven thereby supplies both ends of the cylinders with scavenging air. The output of the inner-crank shaft-ends of the cylinders may be made lower than the outer ends by a. lessened supply of fuel; as a consequence the exhaust pressure will be lower and the scavenging period longer in the inner ends than in the outer ends. Alternatively the exhaust-pressure may be lowered by using turbines &c. of larger cross section with the inner ends.
