Title: Improvements in apparatus for testing gyroscopic instruments
IPC: G01C25/00
Filed: 1944-01-24
Abstract: 574,257. Testing gyroscopic instruments. FIELD AIRCRAFT INSTRUMENTS & EQUIPMENT, Ltd., and AUSTIN, J. Jan. 24, 1944, No. 1291. [Class 97 (iii)] In an apparatus for testing gyroscopic instruments, an instrument-supporting table 1 is secured to the upper end of a spindle 2 carried in a bearing 4 which may be adjustably canted (about a pivot 13) relative to a vertical supporting and driving shaft 8, and the table spindle 2 is mechanically constrained (by a sleeve 3) to rock about its own axis whilst the bearing 4 rotates around the spindle. The bearing 4 after adjustment about the pivot 13 may be locked to the shaft 8 by a screw cap 17, and may be locked to the spindle 2 by a screw cap 22. A screw cap 31 locks the sleeve 3 to the spindle 2. The sleeve 3 is connected to the stationary frame 27 by a link 25 movable only in a vertical plane, and a link 23 connected to the link 25 by a ball joint 26. If the instruments are to be tested for azimuth rotation only, the spindle 2 is brought into alignment with the shaft 8 by adjusting the bearing block 4, this bearing block is locked to the spindle 2 and the sleeve 3 is freed. For simultaneous roll, pitch and yaw testing, the bearing block 4 together with the spindle 2 is canted relative to the shaft 8, the bearing block 4 is unlocked from the spindle 2 and the spindle is locked to the sleeve 3. As the bearing block 4 moves in a conical path and the arm 25 rocks only in a vertical plane, the spindle 2 is rocked about its own axis and the desired motions in three planes at right angles are effected. The instruments (secured to brackets 32) may be placed under vacuum through a flexible pipe connected to a nipple 39. Specification 558,374 is referred to.

Title: Improvements in and relating to multi-shuttle looms
IPC: D03D45/34
Filed: 1937-01-12
Abstract: 488,167. Automatic shuttle-changing mechanism. TRIGGS, W. W. (Crompton & Knowles Loom Works) Jan. 12, 1937, No. 1292/38. Divided out of 485,884. [Class 142 (iii)] The mechanism is the same as that described in Specification 485,884 but the claims differ. Claims 1 and 2 refer to a shuttle receiving support 220 extending rearwardly from a rear wall 2 of the lay and extending forwardly at 235 over the rear wall 233 of the upper and lower boxes 230, 231 at the magazine end. Other claims refer to the shuttle transferring mechanism. Before transfer, the boxes are raised as shown in dotted lines, a cover 236 for the upper box being raised by the engagement of a lug thereon with a stationary cam on the magazine. A fresh shuttle, which has been released from one of the magazine compartments, so as to fall on to the support 220, is now fed forwards into the box 230 by an advancer head 217 on connected arms 214 pivoted on a fixed stud 209 carrying an actuator arm 208, which actuates the arms 214 by means of a spring 215 and carries a pin 210 extending into a slot in a cam-controlled arm 204. Normally the arm moves idly over the pin, but when the weft feeler mechanism indicates substantial exhaustion of weft, a solenoid is energized and in due course a rod 152 is raised. A lifting pin 221 raises the arm 204, so that it now operates the arm 208 and consequently the arms 214. A guide rod 218 extending through a guide eye 219 is carried by the head 217. The spent shuttle is received in the lower box 231 and when the boxes are again lowered into normal weaving position the shuttle is ejected, a stationary shuttle binder 232 being used. The cover 236 has a rib 234 to align with the wall 233, the cover and rib being notched at 237 to permit raising thereof without interfering with the overhang 235.

Title: Optical systems
IPC: G03B41/10
Filed: 1970-01-12
Abstract: 1284992 Optical projection apparatus; projection printing apparatus INTERNATIONAL BUSINESS MACHINES CORP 12 Jan 1970 [16 Jan 1969] 1359/70 Headings G2A and G2J An optical system in which there is relative movement between an object O and an image receptor R, comprises a stationary collimating lens 11 for collimating divergent beams from the object, a planar reflector 13 rotatable about an axis 14 in coordination with the relative movement and which acts as the aperture stop of the system and a stationary lens 12 for focusing the transmitted beam on to the image receptor. An opaque member 15 having a transverse slot 16 is preferably arranged in front of the object such that an illuminating beam from a source (36), Fig.3 (not shown) reflects only an element of a movable object as a divergent beam on to the collimator 11. As the object traverses the slot 16, each element is imaged on the receptor via the reflector 13 such that a perfectly focused image is drawn out on the receptor. In operation as a micro-film document copier the object e.g. a document is fed between sets of rollers (22, 21) whose drive is associated with a control means (25) which synchronizes the movement of rollers (37) of an image receiving surface acting as the receptor and the rotation of reflector 13 by cam (31), cam follower (30) and link (29). In a system in which both sides of a moving document may be micro-filmed, Fig. 5 (not shown) the document moves sequentially between two opaque members having slits (16b, 16b<SP>1</SP>) therein, imaging being achieved via reflection from plane mirrors (43, 44, 45) for one side followed by mirrors (41, 42, 45) for the reverse side. The reflected beams traverse an identical optical system to that of Fig. 1, giving focused images on the receptor (46) and (47) are provided in each light path. Where the object is stationary and the image receptor movable Fig.6 (not shown) the opaque member 15 is placed adjacent the receptor so that that receptor movement is synchronized with that of the reflector. The image receptor may be of the recording, viewing or sensing type e.g. a photographic emulsion layer, a xerographic recorder, a viewing screen, a photosensor diode or photomultiplier tube system. The reflector 13 is preferably elliptical and is lightly constructed so that fast imaging and return cycles may be accomplished. A polysided mirror, Fig. 11 (not shown) having elliptical faces may also be used.

Abstract: 1,178,801. Scouring wool. VEPA A.G. 10 Jan., 1968 [28 Jan., 1967; 14 April, 1967], No. 1362/68. Heading D1L. Apparatus for scouring raw wool, comprises a bath 1 of treatment liquid and at least two conveying elements 6, 12 for moving the wool through the bath, at least one of the conveying elements 6 or 12 being at least partially immersed in the liquid of the bath and that portion which is submerged and is in contact with the wool being conveyed is divided into two sections, a section on to which the wool is fed and which is connected to a source of suction and a section from which the wool is discharged which is connected to a source of internal water pressure. The wool is engaged on only one side of the formed layer by the conveying elements. Wool 7 is fed onto a bath of treatment liquid 8 is sucked against the underside of an inclined endless conveyor 6 which dips below the liquid level. At its lower end the conveyor passes around a perforated roller 9 which is connected to a pump 10 to force liquid from within the conveyor outwardly, through the wool which it discharges upon the conveyor. The wool then floats across the liquid until it is picked up by the upper run of another endless conveyor 12 angled upwardl yout of the liquid and provided with a suction box 13. On leaving this conveyor the wool passes between a pair of squeeze rolls 15. The treatment bath is provided with a perforated floor 2 intermediate the base of the bath and the level of liquid so that dirt washed out of the wool settles in a lower section 4, 5 of the bath and collects as a sludge which is removed. The pump 10 of conveyor 6 also serves to provide the initial suction. In an alternative embodiment (Fig. 2) the conveyor 6 is located horizontally beneath the liquid level and the take-out conveyor 12 is replaced by a perforated drum 17 connected to a source of suction 18. In this embodiment the wool is fed onto the upper run of conveyor 6 and passes around the undersurface of drum 17. In a third embodiment (Fig. 3 not shown) the wool is floated on a liquid treating bath and is successively brought into contact with the underside of two spaced perforated drums, each drum having a plurality of slats around its surface. Each drum has a main chamber connected to a source of suction which draws the wool against the drum surface and the treating liquid therethrough. In a lower quadrant of each drum is a chamber into which liquid is pumped from the bath through an end face of the drum, the liquid then being forced out through a perforated plate, the perforated drum surface, and through the fibres thus detaching them from the drum face. At the discharge end of the bath there is again provided a perforated drum connected to a source of suction.
