IPC: B67D7/16
Filed: 1925-02-18
Abstract: 252,427. Messpumpen-Ges. Scharffe & Co., and Scharffe, C. A. Feb. 18, 1925. Measuring-devices.-In apparatus for delivering measured quantities of petrol &c., the liquid is delivered by a pump &c. to one or more measuring chambers 7 provided with one or more overflow pipes 26 - - 29, the inlet and outlet being controlled by a cock 35 which co-operates with the overflow cock 24 in such a manner that the movement of the counting mechanism 44 - - 46 is determined by the overflow cock, and the counting is effected when changing the cock 35 over from inflow to outflow. The cock 35 carries a cam 36 which, when the cock is set for inflow to the vessel 7, allows a lever 38 to rise so that a spring-pressed rod 39 may enter one of the slots 30 - - 33 in a disc 25 on the overflow cock 24, the depths of these slots being proportionate to the heights of the overflow pipes 26 - - 29. At the same time a pin 39<a> carried by the rod 39 releases a toothed wheel 41 on the pump shaft and allows the pump to be operated. When the cock 35 is turned for outflow the cam 36 depresses the lever 38 and disengages the rod 39 from the disc 25, thereby locking the wheel 41 and operating the counting gear 44 - - 46. A pin may be provided on the cam 36 to engage an arm on the lever 38 and prevent the cock 35 from being turned in case the rod 39 has not entered one of the slots 30 - - 33. In another form, the counting mechanism is operated by a lever which pivots on a cam carried by the overflow cock, the rise of the cam being proportionate to the setting of the overflow. The lever is lifted by an arm on the cock 35 when the latter is turned and the movement of the end connected to the counting mechanism is proportionate to the setting of the overflow. In another form, the counting-mechansim is operated by a sliding disc on the cock 35 which is moved a varying distance by a cam on the overflow cock. In another form, the counting mechanism is operated by two cams on the two cocks and two levers engaged thereby.

Title: Variable energy ion beam source and analytical apparatus incorporating same
IPC: H01J49/26
Filed: 1976-02-05
Abstract: 1509697 Ion sources; mass spectrometers E I DU PONT DE NEMOURS & CO 5 Feb 1976 [13 Feb 1975] 4567/76 Heading H1D A variable energy ion beam source for a mass spectrometer (Fig. 3, not shown) which is coupled to a chromatographic column includes, between polepieces 80 and 81, an ion-forming region R into which the gas from the column is introduced at low pressure, and into which an electron beam 73 is directed from the cathode 69 to ionize the gas, the beam being formed by the repeller electrode 50, first and second alignment electrodes 51 and 56, entrance electrode 57 with slit 58, and, optionally, extraction electrode 55. In operation, the beam energy is varied, while maintaining the beam focussed, by simultaneously varying in a specified manner the potential of all the electrodes with respect to the entrance electrode 57. The first and second alignment electrodes are each in the form of a pair of plates, for each pair the potentials of the two plates being separately variable, whereby the beam may be maintained focused on the entrance electrode slit 58 as the beam energy varies. The magnetic sector mass spectrometer includes, immediately before the entrance slit to the detector, a pair of electrodes (216, 217, Fig. 3, not shown), one either side of the beam, to which A.C. is supplied to oscillate the beam across the detector slit for the mass spectrum range below about 300 AMU, to ensure that the narrow mass lines produced in that range of the spectrum are not obscured when the spectrometer is employed in a mode in which the ion beam energy is varied in discrete steps. To prevent gas discharge in the conduit coupling the chromatograph column to the mass spectrometer, both the pumping system and conductive shields around the conduit are held at the ion beam source potential. The conduit includes a helix of capillary tubing to produce the required decrease in pressure.

[Class 142 (i)] Relates to binding selecting devices for electrically controlled brocade looms and /or card-punching machines of the type wherein the original pattern or design is scanned electrically or photo-electrically, whilst the binding to be used for different parts of the design is selected by standard binding cards giving plain, twill, satin or other weave. The design carried on a rotating drum 1 and illuminated by a spot light is scanned by a photo-electric cell connected to an amplifier 5, a relay 6 and contacts 7, 8, which may be operated respectively by dark and light portions of the design and are connected through terminals 23 to the conductor plates 21 of binding selecting switches. The switch for the dark portion comprises spring-controlled contacts 26 equal in number to the number of design elements in one line of the original design, these contacts being conductively connected to the plate 21, and acted upon by woven texture or binding selecting cards 19 passing over a cylinder, which is rocked about a pivot 181 and rotated by a pawl 17. Blank parts of the card press the contacts 26 into contact with fixed contacts 24 mounted in an insulating plate 22 and connected to respective selecting electromagnets 11 and contacts 12, which are electrically connected in succession through a rotary brush connector 14, a brush 13, a battery 10 and an adjustable resistance 9 to the relay. The electromagnets 11 control the warp lifting or card punching devices, for example as described in Specification 427,357 a particular magnet being only energized if the contact is operated and at the same time a blank portion of the binding card 19 is situated opposite to the corresponding moving contact 26. The contact 8, which may be actuated by bright parts of the design, and the electromagnets 11 are connected to fixed contacts 241 of a switch similar to the switch described, but provided with cards 19<1> for determining the binding in bright parts of the design. Modifications are described in some of which the relay is omitted and each electromagnet has two component electromagnets, one for example for white warp and the other for black warp. Penetrating light is used in some cases. A conductivity instead of a photo-electric control may be used, and instead of pattern cards, a pattern board with concave and convex portions may be used. Specification 417,387 also is referred to.
