Title: Improved method and apparatus for variable steady current compensation of detectors used in gas chromatography
Inventor: MILACEK STANISLAV
IPC: G01N30/86
Filed: 1965-07-01
Abstract: 1,108,613. Gas analysis. LABORATORNI PRISTROJE NARODNI PODNIK. July 1, 1965 [July 13, 1964], No.27870/65. Heading G1N. To provide a constant standing D. C. current in the output signal of a flame-type ionization detector 2, Fig. 1, responsive to the output gases of a gas chromatograph column (not shown) variations thereof as the temperature of the column is changed according to a predetermined programme, is cancelled at the input to an amplifier 3 driving a recorder 4, by a current which is obtained from a compensation circuit 5, 6, 7, 8, 9 and which is arranged to vary in an equal and opposite manner. The compensation circuit includes integrators 6, 7 having adjustable time constants, fed from a stable D. C. source 5 via an adjustable potentiometer 8, and an adjustable output potentiometer 9, adjustments being made to provide a time-varying output (12) at 9, which is equal and opposite to the standing current variation (11) of the detector 2. The standing current curve (11) is obtained by operating the chromatograph with only carrier gas passing through it, and no sample gas, and recording at 4, the detector output. Instead of actually recording the current curve (11) and manually adjusting the compensation circuit to match it, the detector output may be stored by optical or magnetic memory devices, of digital or analogue type, the stored signal being reproduced when required to cancel the standing current during a test on a sample gas. Having stored the compensating current characteristic by one method or another, and before a measurement on a sample gas is conducted, a second test with carrier gas and no sample gas may be carried out to ensure that the output of amplifier 3 is in fact a constant current (13).

Title: Improvements appertaining to the manufacture or production of stockings
IPC: D06H3/16
Filed: 1930-06-16
Abstract: 340,033. Hebblethwaite, A. G., and Hurtley, F. June 16, 1930. Turning sewn articles inside out.-In an air current stocking &c. turning apparatus, a pedaloperated valve is provided for reversing the direction of the current. The current is set up by a fan b operated by a motor and causes air to flow along the tube s on which the stocking is held by the operator. The direction of the current is governed by the valve vane g, held in the normal position by a spring and pulled into the opposite position by a pedal chain. In the normal position, shown in full lines in Fig. 2, the fan b sucks air along the tube s towards the fan. If turned to the position shown in dotted lines, air is sucked up through a hole in the casing d into the fan chamber and expelled through the pipes t', s so producing a current in the pipe s in an outward direction. In turning stockings the end is held by the operator and the toe sucked into the tube. If the stocking is inadvertently released by the operator, a gauge stop 40, Fig. 7, and hinged tube permit of its easy recovery.

Abstract: 490,575. Explosive land mines. HUYBRECHTS, L., and SPILTHOOREN. M. Oct. 21, 1937, No. 28671. Convention date, Oct. 22,1936. [Class 9 (ii)] Relates to explosive land mines fired by the deformation of a buried device by the passage of a load above ground, the deformation of the device serving to actuate a transmission mechanism which operates a firing-pin. According to the invention, a deformable device comprising at least two superimposed platforms 1, 2, Fig. 15, normally held apart by fluid or mechanical means is arranged as a self-contained unit adapted to be transported and mounted in position independently of the explosive charge container 52 and transmission mechanism 20. The two plates 1, 2 may be normally held apart by a rubber tube 3, Fig. 3, containing a gas or a liquid, and by springs 10. The tube 3 is connected to pipes 7 leading to a flexible diaphragm 13 connected to a Bowden wire mechanism 16, 20, the other end of which is connected to the striker mechanism of the explosive charge. Operation of the diaphragm may be prevented by a valve device interposed between the pipes 7 and the diaphragm. This device 31, Fig. 10, contains a valve 41 and a piston 40. The piston bears against a spring 39 supported by a disc 38 adjustable by a screw 36. The valve 41 is held to its seat by a spring 45, and can be opened by means of a lever 47 and a rod or cable 51 operated from a distance. The striker mechanism comprises a firing-pin 65 held cocked against a spring 66 by a trigger 72 connected to the Bowden mechanism. The firing-pin is locked at safe by hinged catches, which are swung out when released by a pull on a rod or cable 77. This mechanism is enclosed in a casing 86 attached to the casing 52 containing the explosive charge 58 and priming cartridge 57. In a modification, the deformable device comprises a ribbed top plate fastened over a flat bottom plate, forming therewith a deformable fluid chamber connected by a central pipe to the diaphragm device. In another modification, the plates are separated by lazytongs. As shown in Fig. 17, several such deformable devices and explosive charge containers 52 may be buried in a road s, the safety devices being operable from points 102 at the sides of the road:

Abstract: 1464063 Metal vapour lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 July 1975 [11 July 1974 5 June 1975] 28682/75 Heading H1D [Also in Division C1] A low pressure discharge lamp (e.g. Hg or Na with or without luminescent coatings) has a solid filamentary body permeable to the discharge; the body being present over at least half (e.g. 80%) the electrode distance and thinly distributed over the space, the ratio between volumes of body and space being between 3.10<SP>-7</SP> f/# and 3.10<SP>-2</SP> f/# where f is the quotient of the volume and area of the body in microns and # equals 5 microns. The body may be interrupted, as shown into packets 7, 8, 9. The light output of the lamp may be increased without increase of energy consumption by the lamp and stabilizing element. Between 5 x 10<SP>-6</SP> and 5 Î 10<SP>-3</SP> mg. of the body/cubic mm. may be present. Preferably the electrode distance/ cross-sectional diameter of the discharge space is >5. Preferably the density near the axis differs from that near the wall. A reduced near axial density reduces uneven temperature distributions producing mercury or sodium deposits, while an increased near axial density in a circular-cylindrical lamp increases light output. The body may be glass, quartz or metal (e.g. W) wool for example. Metal wool may be provided with insulating material to improve potential distribution, and the wire may be 5 to 100 Ám diameter. The body may be luminescent glass or glas coated with Mn and/or Sb activated calcium halophosphate for example or gehlenite glass for sodium resistance. Excessive absorption may be countered by a surface reflective coating of zirconium oxide, magnesium oxide or barium sulphate. Cooling for optimum efficiency may be by radiation shields on the electrode stems, or alloys in the discharge space (e.g. In or Hg amalgams). The lamp may be U-shaped (Figs. 3, and 4, not shown). Comparative test results are detailed and specify for example, dimensions, pressures, currents and efficiencies. Hg may be with 75% by vol. Ar and 25% by vol. Ne at 2À5 torr, or with 72% by vol. Ne and 28% by vol. He at 4 or 6 torr. A favourable ratio of power supplied/losses in the power supply apparatus is obtained for V/l<7, where V is the operating voltage in volts and l is the electrode separation in ems. Reproduction applications using aperture lamps is mentioned.
