Title: Metering valve for introducing a fluid under pressure into an analytical apparatus
Inventor: BONNET E
IPC: F16K21/00
Filed: 1970-04-03
Abstract: 1,267,295. Sampling valves. ENTREPRISEDE RECHERCHES ET D'ACTIVITES PET ROLIERES (ELF). 3 April, 1970 [10 April, 1969], No. 15864/70. Heading B1X. [Also in Divisions B8 and F2] Samples for introduction into analytical apparatus particularly gas chromatographs, are taken from a fluid stream flowing from inlet 18 to outlet 20 by unscrewing spindle 10 so as to lift cone 8, thereby allowing the stream to flow through sample passage 26, then screwing down spindle 10 so that cone 8 forces trap 24 down against spring 28 until passage 26 containing the required sample is closed at the lower end by cone 6. In this position, the stream continues to flow through the valve by means of ducts 30 which open when trap 24 is moved away from abutment against shoulder 22. With the sample in passage 26, the valve is flushed, dried with compressed air, weighed if desired, heated to the required operating temperature, and connected to a stream of carrier gas passing to the analytical apparatus. Spindle 10 is fully unscrewed and the sample is swept from channel 26 by the carrier gas. The system is of particular application in the gas chromatographic determination of heavy hydrocarbons.

On energizing solenoid 128, plunger 130 lowers tab 132 into the radiation for testing or calibration or equalizing the areas of cross-section of the chambers. Each unit 36 has photo-resistors 172, 174, mounted on block 62 adjustable in slot 54 and generating phase reference signals due to lamp 64 and chopper windows 140-146. The adjustment is enabled by access openings. Plate 74 is strengthened by longitudinal ribs.

Title: Control circuit for stepping motor
IPC: G05D3/18
Filed: 1972-04-07
Abstract: 1382669 Ring counters GENERAL ELECTRIC CO 7 April 1972 [23 April 1971] 16108/72 Heading G4A [Also in Divisions H2 and H3] A ring counter for energizing the stator windings 32, 34, 36 of a stepping motor for a tape drive system (see Division H2) comprises silicon controlled rectifiers 82, 84, 86 respectively in series with the windings.32, 34, 36 and controlled by the resistor, capacitor and diode circuits shown in response to pulses generated by a pulse generator 40 forming part of the tape drive system. When power is applied to the counter (with none of the SCR's 82, 84, 86 conductive), current through resistor 120 is directed to the series circuit comprising members 128, 130, 92 rather than through one of the diodes 122, 124, 126, thus firing the SCR 82. The resultant negative coupling from this SCR to the diode 94 through resistor 106 causes discharge of capacitor 96 to bias the diode 94 to pass the next pulse produced by the generator 40. When this occurs, the SCR 84 is fired and SCR 82 is commutated via capacitors 112, 114. Subsequent forward biasing of the diode 100 ensures firing of the SCR 86 by the next pulse to complete the three-state sequence of the counter.

The front portion 4 of member 3 is of scoop-like form, and tapered as shown to enable the corrosive substance to be applied to corners.  The flexibility of the member facilitates the application of the corrosive substance. The alternative form shown in Figs. 3 and 4 has a rear tubular part 10 and a concave V-shaped gap 11 in its front part 12.  A circular disc 14 of rubber may be threaded on to the handle of either form to shield the user's hand (Figs. 1 and 2), or an integral annular external flange 16 (Figs. 3 and 4) may be provided for the same purpose.  In either form the portion or each portion of scoop-like form may have one or more holes, as at 17 (Figs. 1 and 2) to permit passage of the corrosive substance. The hole or one of the holes may be arranged centrally and be connected by a straight slit 18 to the tip of the portion.

IPC: D01B1/22
Filed: 1925-06-26
Abstract: 258,929. Sharp, P. June 26,1925. Breaking and scutching apparatus; carding- engines; heckling - machines.-Jute, hemp, flax, and like fibres are passed between a series of pairs of rollers with coarse helical flutes and then between a longer series of pairs of rollers with straight and finer flutes the upper roller of each pair being given a rolling motion over the lower roller. Lubricant is sprayed on to the material during any stage of the treatment. The material is then passed to a heckling and carding machine provided with cne or more combing- rollers rotating in the opposite direction to the workers or strippers and having pins pointing in a direction opposite to the direction of rotation. The material may be passed 'automatically from one device to the other to form a continuous process. The fibres are passed from a conveyer 1, Fig. 1, through a pair 2 of straight fluted feed rollers to a series of pairs 3 of helically and coarsely fluted rollers. They are then fed by a pair 4 of straight fluted rollers to a series of pairs 6 of straight and finely fluted rollers, the upper roller of each pair being given a rolling motion over the lower one. The upper rollers are carried in arms 8 pivoted on the axes of the lower rollers and rocked by eccentrics 10. The upper rollers are weighted by springs 11. The rollers 6 rotate more quickly than the rollers 3, and may be divided into sections, the later section rotating more quickly than the previous one. Lubricant may be sprayed on the fibre at any stage in the machine from a tank 30 through a nozzle 32. The lubricant may be sprayed under pressure, and a number of nozzles arranged to cover the whole surface of the fibres may be employed. The material may be passed either direct, or through an additional set of rocking-rollers, to a conveyer 34a, Fig. 3, which carries it to a single heckling, carding, or combing machine. A takerin 35 delivers the fibres to a cylinder 34 provided with strippers 36 and workers 37. Additional rollers 38, 38a are provided in any appropriate position. These rollers rotate in the opposite direction to the usual strippers and workers and their pins point in the opposite direction to the direction of rotation. The fibres are taken off by a delivery roller 39 and are fed down a guide 42 to a rotary drawing-head E.

This is achieved by arranging that W =103/fy to 124 /fy and T = 113/fx. Preferably W=113/fy. The length L is chosen from the curves of Fig. 3, in accordance with the lower frequency fy, the value of T /fx and the width. Examples are given in the Specification of typical dimensions so determined. These dimensions correspond to the " normal mode" of oscillation in the Y-axis. In addition specific examples are given for " higher " and " lower " modes of oscillation. The crystal may be used in a backcoupled oscillator, Fig. 4, having a switch 51 for tuning to either of the frequencies fx, fy.
