Title: Improvements in or relating to means for removing water from coils of yarn
IPC: D06B15/10
Filed: 1958-08-15
Abstract: 844,554. Centrifugal driers. SCHOLL A. G. Aug. 15, 1958 [Sept. 2, 1957], No. 26264/58. Class 34(2) Apparatus for drying coils of yarn comprises conveyers 12, Fig. 1, which automatically charge cages 1 in which the coils are subjected to centrifugal action and means for automatically charging the cages.. The conveyer 12 has locating stems 18 for the coils and a guide plate 25 which is interrupted in the region of arbors 4 situated within the cages 1 for the reception of the coils from the stems 18. The cages are housed in a common housing 2 which is mounted for pivoting together with the cages on a shaft 3, the discharge position being shown in dot-and-dash lines. The shaft 3 carries a sprocket 5 connected by a chain 7 to a drive sprocket 6 which is connected by a slotted rod 11 to a piston 9 in a hydraulic cylinder 10. Movement of the piston 9 is automatically controlled by an electrical circuit, Fig. 3 (not shown), so that when wet coils leave the' conveyer they pivot a flap valve 49 connected to a switch which actuates magnetic valves to feed oil to a container 39 in which are situated hydraulic motors to drive the cages until a time switch relay stops them and allows the piston 9 to move downwardly and so pivot the cages to the lowered position to discharge the coils. In falling the dry coils pivot a flap valve 61 which actuates a switch which is connected through step-by-step switches with the magnetic valves so that the piston 9 moves upwardly to raise the cages to the charging position. In a modification a shaker conveyer with channels 70, Fig. 4, for the yarn coils 71 has guide springs 73 to guide the falling coils on to arbors 74 in cages 75 which cages have a pivotable mounting 76 and individual drives. Means 72 are provided to retain the coils on the conveyer until required, which are so operated that when each mounting turns from its discharge position to its operative position a flap 85 thereon turns a lever 82 so that a link 81 and a lever 78 are raised and an arm 80 clears a coil 71 in a channel and allows it to travel into the cage.

Filed: 1971-04-19
Abstract: 1301065 Isotachophoretic separation LKBPRODUKTER A B 19 April 1971 [8 April 1970] 26526/71 Heading C7B In isotachophoretic separation of charged particles of the same polarity, the particles, a leading ion of the same polarity but of greater mobility than that of any of the charged particles, a terminating ion of the same polarity but of lesser mobility than that of any of the charged particles and a counter ion which has a buffering effect and is of opposite polarity to the leading and terminating ions, are subjected to electro-phoresis; a mixture of amphoteric substances is added to the charged particles to form a mobility and pH gradient in the electric field; the mobility range of the amphoteric substances extends over the range of mobilities of the charged particles and each amphoteric substance differs in mobility and isoelectric point from other such substances in the mixture by only a small amount. The particles undergoing separation may be proteins or amino acids. The amount of sample added to the electro-phoresis column is not critical since a protein becomes charged during the process and its solubility thus increases. The separation provides a concentrating effect. The degree of separation can be increased using a counter flow, and stabilizers such as a gel or powder, are used. The ampholyte mixture can be as set forth in Specification 1106818. Examples are described.

In a method of measuring a variable quantity such as the angular displacement of an output shaft of a machine by comparing it with a fixed or variable reference value, e.g. the angular displacement of an input shaft, an A. C. signal representing either the value or the quantity is applied to intensity modulate a modulatable light-source optical gratings are caused to move relatively to one another in accordance with either the quantity or the value respectively, and the output of a photo-cell illuminated by the source through the gratings provides a signal representing the difference between the quantity and the value. The amplified output from a photo-cell PE1, Fig. 2, actuated by a tungsten lamp TL1 through a driven radial grating RG1 and an index grating IG1, is applied to a gallium arsenide lamp GAL serving as a source to a similar pair of gratings coupled to an output shaft. The rectified output of photocell PE2 of the last named gratings provides an error signal for control or other purposes. The motion of a single body, rotary or linear, may be controlled by an oscillator output or by a recorded signal being used to modulate the light-source of a pair of gratings one of which is coupled to the body. The phase of the modulation relative to the photo-cell output should be such as to produce maximum signal on departure from zero error.
