Filed: 1972-05-18
Abstract: 1339880 Ionisation gas detectors KERNFORSCHUNG mbH GES FUR 17 May 1972 [18 May 1971] 23049/72 Heading G1N [Also in Division H1] The concentration of components and pressure of a binary gas mixture having components of different ionisation cross-section are determined simultaneously by providing the gas mixture and a calibration gas of known composition at equal pressures in respective ionisation chambers 6b, 6a, the ionic current produced in the binary gas mixture being dependent upon the concentration of its components and the pressure, and the ionic current produced in the calibration gas being dependent only upon the pressure thereby enabling determination of both concentration and pressure. As shown, the chambers are separated by a thin diaphragm 13 which allows the pressures of the binary gas mixture and the calibration gas to equalize. In the construction shown in Fig.2, each chamber is provided with a cylindrical outer electrode 2 and an inner electrode 2', the electrode 2 having its interior surface coated with radioactive material. Alternatively, a portion of the electrodes 2 may be common to each chamber, the common portion being provided with a window which is closed by a common radioactive source.

Title: Improvements in or relating to alumina material
IPC: C01F7/441
Filed: 1963-06-10
Abstract: Alumina material having a low sodium content is produced by selectively calcining an alumina trihydrate to obtain a transition alumina (i.e. an intermediate decomposition product between the stable hydrated crystalline form and the completely anhydrous corundum) capable of at least partial rehydration, agglomerating the transition alumina by mixing it with water, partially rehydrating the alumina agglomerates, circulating water, preferably hot water of low sodium content, e.g. distilled or deionized water, to remove soluble sodium compounds therefrom while continuing the rehydration of the partially rehydrated alumina agglomerates, and removing uncombined water by drying or activating.  The rehydrated alumina pellets may be activated by being heated.  After drying, the pellets may be ground to give a powder product.  The pellets are preferably subjected to the circulatory stream of hot water until the concentration of sodium as Na2O in the pellets is less than 0.03% by weight.  The water may be circulated through a column in which the pellets are contained. The water may be passed through an ion exchange to remove a substantial proportion of sodium therefrom, and the water may be recirculated through the column of alumina granules.  The circulating water is preferably at a temperature of at least 80 DEG  C. Selective calcination may be accomplished by passing alumina trihydrate rapidly through a hot zone, and the trihydrate is advantageously calcined to a loss on ignition of 5 to 10%.  The selectively calcined alumina may be ground prior to agglomerating.

Title: Improvements in or relating to corpuscular beam apparatus
IPC: H01J37/20
Filed: 1968-05-21
Abstract: 1,224,644. Discharge apparatus. SIEMENS A.G. 21 May, 1968 [22 May, 1967], No. 24058/68. Heading H1D. In corpuscular beam apparatus, such as electron microscopes, ion microscopes or diffraction apparatus, an object table or the object mounted thereon is displaceable by means of a remotely controlled servo-motor system which comprises at least one stepping motor and control means which feed pulses to the motor from a pulse generator 57 via means 56 for predetermining the number of control pulses for a desired object displacement. The object may be displaced in the direction of the beam or tilted or rotated with respect to the beam axis. As shown the table is moved in two mutually perpendicular directions in a plane perpendicular to the beam axis by two plungers each plunger being moved by a spindle including two universal couplings turned by a servomotor via a gear-box and an electromagnetic coupling which also permits the spindle to be manually rotated. One servomotor having terminals A, A<SP>1</SP>, B, Bl is actuated by contacts 52, 53 mounted on a slidable bar 40 which is spring loaded against the bearing surface 48 of a lever 49. A second motor is actuated in the same manner by a second bar (41), Fig. 4 (not shown) mounted at right angles to bar 40. Moving lever 49 brings contact 52 against contact 54 or 55 and connects the generator 56 to the motor via a switch 58 and an adjustable pulse counter 57, which when the predetermined number of pulses have passed opens switch 58. The displacement of the motor depends on the number of pulses whilst the speed depends on the pulse frequency which is increased by the other contact 53 moving along a potentiometer 59 in the frequency determining circuit of the pulse generator. The bars 40 (41) are positioned so that the direction of movement of the lever 49 and object table correspond. The apparatus permits automatic repeatable step-by-step scanning of an object. Additional motors may be used to rotate or tilt the object which may be in a tilting cartridge on the table or to displace it in an axial direction during fine focusing. The bars may be mounted one above the other in a single plane. The pulse counter may be adjusted to compensate movement of the object table due to thermal effects.

Title: Bobbin stripper
IPC: B65H67/06
Filed: 1961-07-05
Abstract: 959,480. Collecting, delivering and stripping bobbins. MONSANTO CHEMICAL CO. July 5, 1961 [July 29, 1960], No. 24307/61. Heading D1F. An apparatus for stripping waste yarn from a flangeless bobbin comprises a rotatable table that carries a bobbin along a linear path beneath a cutter, the apparatus including means whereby the cutter is raised above its bobbin-stripping position whilst the ends of the bobbin pass under the cutter. As shown a rotating table 12 carries a plurality of radially extending cylinders 19 each of which houses a plunger 20 pivotally carrying a bobbin support 22. Each support 22 has a pair of rollers 42 that run in a groove encircling a base 11, the groove being straight at 44, where it passes a shoot 38 containing used flangeless bobbins,to cause the carriers to travel parallel to the longitudinal axis of the bobbins awaiting collection at the end of the shoot and to cause each carrier to pick up a bobbin. The groove is also straight at 45 where it passes a cutting station 24 so that at this station each bobbin will be moved along its longitudinal axis to permit a cutting disc 47 to be lowered on to the bobbin to cut the wast yarn therefrom. The cutting disc is normally biased downwardly by spring means 56, but the disc is displaced upwardly each time a roller 60, on an arm carrying the disc, is raised by spaced cams 68 or a plate 61 rotating with the table 12. This upward movement of the cutting disc 47 allows it to clear the leading and trailing ends of the bobbins. A suction duct 48 removes the waste material. Discharging cleared bobbins., Pivotally mounted on each carrier 22 is an ejector plate 70 disposed radially inwardly of a bobbin in the carrier 22. As each carrier 22 approaches a discharge shoot 67, an arm 74 extending radially inwardly from the plate 70 is deflected downwardly by engagement with a bracket 73 and this causes the ejector plate 70 to pivot in a manner kicking the cleared bobbin off the carrier 22 and into the shoot 67.
