Abstract: 618,376. Optical gauging apparatus. REID & SIGRIST, Ltd., and CANTLE, L. G. H. Oct. 29,.1946, No. 32110. [Class 106 (ii)] [Also in Group XX] A device for testing the parallelism of two surfaces comprises a collimating lens with a light source in the focal plane thereof so that parallel light from the lens strikes a mirror which is disposed at right angles to the lens axis and is located by one of the surfaces, and also strikes another mirror located by the other surface; the parallelism between the surfaces is determined by measurement of the distance between the two images of the light source formed by reflection in the mirrors, these two images being focused on a scale in the focal plane of the lens, or in the space adjacent the light source, in which case the distance between them is found by using an eyepiece, for example. In the form shown, the collimating lens 14 and a glass disc 15, the surface 16 of which is silvered and which is apertured at 17 (or the disc may be silvered at its margin, the centre being clear), are carried by the part 12 of a telescoping tube 11, 12. Rotatable around the part 11 is a head 19, which slidably carries a magnifying eyepiece 21 and has fixed thereto a plate 30 bearing a scale, which is illuminated by light from a lamp and condenser unit, that is reflected by the surface 31 of a prism, through a slit in opaque material, disposed between the prism and the plate 30 on which it is mounted. The mirror 15 is placed on the surface 38 of the lens mount 37 of a photographic camera, while a mirror 34 is placed in contact with the film guide 39. Looking through the eyepiece, two images are seen on the scale and the separation thereof indicates the angle between the lens mount and film guide. Hence, one or other of these elements can be positioned correctly so that they are parallel.

Title: Improvements in or relating to floor conveyors
Inventor: ORWIN OLAF JOHN BARCLAY
IPC: B61J3/00
Filed: 1959-09-25
Abstract: 896,530. Floor conveyers. FISHER & LUDLOW Ltd. Sept. 14, 1960 [Sept. 25, 1959], No. 32605/59. Class 104 (2). In a floor conveyer in which a driving chain 12 is disposed below the floor level 11 and is provided with dogs 14 which releasably engage a drivetransmitting member 19, passing through a slot 13 in the floor, to drive carriers 10, each carrier 10 is itself vertically displaceable relative to its drive-transmitting member 19 so as to enable the carrier 10 to ride over minor obstructions without disconnecting the driving connection between the dog 14 and the member 19 and each carrier is provided on its front with a buffer 30 which, on engagement with an obstruction, lifts the member 19 out of driving engagement with a dog 14 but not out of the slot 13 so that the member 19 can return to a position in which it can engage a dog 14 once the buffer 30 disengages the obstruction. In the arrangement shown, the drive transmitting member 19 is of rectangular cross-section and is freely vertically movable between pairs of rollers 20 supported between plates 18 secured to the front of the carrier 10. The member 19 is provided with a transverse pin 23 which passes at each end through slots 22 in the plates 18 and carries on each end rollers 24. The buffer 30 is pivotally mounted on a transverse shaft 34 provided on the front of each carrier 10 and on meeting an obstruction is pivoted in a clockwise direction to move the inclined edges 37 of arms 36 into engagement with the rollers 24 to lift the member 19 out of driving engagement with a slot 15 provided in the dog 14 but not out of the floor slot 13. Once the obstruction is removed the buffer is returned to its initial position by springs 38 to disengage the arms 36 and rollers 24 to allow the member 19 to fall. The amount the member 19 falls is limited by rollers 29, mounted on a transverse pin 28, engaging the floor 11 to prevent the end 25 of the member 19 engaging the chain 12. The forward ends 16 of the dogs 14 are inclined upwardly and rearwardly to the direction of movement of the chain 12 to facilitate the entry of member 19 into engagement with the slot 15. A lever 39 pivotally mounted on the top of the member 19 is provided with a heel portion 41 which engages a fixed abutment plate 42 to lift, when partially rotated, the member 19 out of engagement with the dog 14 but not out of the floor slot 13 but when fully rotated to lift the member 19 clear of the floor slot 13.

Abstract: 930,847. Radar. DECCA Ltd. Sept. 18, 1961 [Sept. 22, 1960], No. 32634/60. Class 40 (7). [Also in Group XX] A plotting device comprises a cathode-ray tube or other screen 10 on a mobile craft displaying plan-position radar information in combination with a transparent plotting member 25 carried on a parallel motion linkage 21 ... 24 for movement without rotation over the surface of the display screen, pivot means being provided enabling the plotting member to be swung away from the display screen. The invention is concerned with the assessment of risk of collision with other ships. Tubular links 21 are carried by rod 20 by means of a tubular spacer 26 forming a pivot rotatable on, and slidable along, the rod; tubular pivot 22 serves as a spacer for links 21 and carries links 23 which are joined by member 24. The linkage prevents rotation of the plotting member. Range and bearing graticules may be engraved on the plotting member. The display may be " ship's-head-upward " or " northupward." In the arrangement illustrated in Fig. 5 one corner of plotting member 25 carries a pivot 40 for an arm 41 having a slot 42 through which there extends a fixed pivot 43 with a locking nut 44; arm 41 is set in the direction of the ship's heading with pivot 43 positioned in slot 42 such that the interpivotal distance corresponds to a desired radius of arcuate movement of the plotting member (see also Figs. 2-4, not shown). A bearing scale 46, which is a compass rose when the display is " north-upward," is provided on the plotting member. In a further embodiment a second arm is pivoted about a first arm itself pivoted on a pin in the plotting member, Fig. 6 (not shown). The use of the embodiments is detailed.

Title: Electromagnetically operated rotary actuators
IPC: H01F7/14
Filed: 1961-09-12
Abstract: 1,005,920. Electromagnets. ILLINOIS TOOL WORKS Inc. Sept. 12, 1961 [Sept.12, 1960], No. 32722/61. Heading H1P. In an electromagnetic actuator, particularly for use in space vehicles capable of high acceleration, energization of the electromagnet results in linear displacement of the armature which results in rotation of a shaft coaxial with the electromagnet, but means are provided for preventing rotation of the shaft because of unwanted linear movement of the armature (e.g. due to acceleration of the whole device). Fig. I shows a soft iron shell 12 fixed to a ferromagnetic core 22 carrying a coil 16. An armature 42 carries a tubular member 48 slidable on a shaft 32. Rotation of the armature is prevented by balls 64 or pins located in slots 60, 64. A ferromagnetic disc 74 is supported on screws 76 and biased away from the core 22 by springs 78. An arm 82 fixed to shaft 32 engages a sear 90, preventing rotation of shaft 90 in one direction. A pair of rollers 54, pivoted on a pin 56 in shaft 32, engage a cam surface 58 so as to prevent rotation of shaft 32 in the other direction. When the coil 16 is energized, the flux available at non-magnetic gaps 70 causes the disc 74 to be attracted to the left, releasing the sear 90 from the arm 82. The armature is also displaced to the right so that the shaft 32 is rotated under action of the cam surface 58 and rollers 54. A spiral return spring 66 is provided. The armature is lubricated with molybdenum disilicide. Fig. 3 shows another actuator in which the ferromagnetic disc 74a is biased to the left by spring washers 94 and carries a thrust bearing 34a. Unwanted acceleration of the whole device causes movement of members 42a, 48a, 34a, 32a and 74a to the right so that no relative movement of cam surface 52a and rollers 54a occurs and hence no rotation of shaft 32a. When the coil 16a is energized, the armature 42a and tubular member 48a are displaced relative to rollers 54a so that partial rotation of shaft 32a occurs. Actuators with two armatures.-In Fig. 6, a pair of armatures 42b are mounted on tubular members 48b, 106 and are separated by springs 110. Balls 64b in slots prevent rotation. When the whole device is accelerated, one of the armatures 42b may be displaced until a shoulder 105 engages a stop 104. The serparation between cam surfaces Ò8b, 108 is, however, sufficient to ensure that rotation of shaft 32b will only occur if both armatures are moved towards one another by energizing coil 16b. Specification 842,098 is referred to.

Abstract: 447,336. Delivery-stopping and rollerweighting apparatus for spinning- machines. MACKIE & SONS, Ltd., J., and MACKIE, J. P., Albert Foundry, Belfast. Nov. 15, 1934, No. 32929. [Class 120 (ii)] In spinning-machines for long fibred material such as flax, hemp, and jute the pressuremeans of the feed rollers is so arranged that, upon breakage, the point of application, or the direction of the pressure, or both, is altered so as to operate to separate the rollers. A lever 10, when released upon breakage by a detector 16, turns about a pivot 11 so that the weight 8 which normally applies pressure to the feed rollers serves, by means of a toggle connection, rack gearing 22, 23, Fig. 4, or by the disposition of a lever 7, to assist the separation of the rollers. The detector 16 raises the latch-rod 14 which allows the lever 10 to swing about the pivot 11 under the action of the weight, and, in the arrangement shown in Figs. 1 and 2, the limb 13 of the weight lever 7 engages the pivot 11 whereupon the limb 12 engages the trunnion of the pressure roller 2 which then moves with the lever under the action of the weight 8 until a stop 19 on the detector engages a projection 20 on the latch-rod 14, as shown in Fig. 2. The upper end of the lever 10 clamps the material against the rail 18. In the arrangement shown in Fig. 4, pivotal movement of the lever 10, removes the weighted pinion 26 from the rack 22 to the rack 23. It is stated in the Provisional Specification that the feeler arrangement described in Specification 425,612 may be used.
