IPC: F41G7/26
Filed: 1954-05-05
Granted: 1974-10-31
Abstract: An aircraft navigation system particularly for assisting an aircraft to land, employs a reference point on the ground which can be a transmitter, and a receiver on the aircraft, and an angular speed measuring device. When the axes of rotation of the angular speed measuring device and the receiver are parallel, the angular displacement of a sighting device, using selsyns, is a function of the angular speed of the device carrying the receiver, lining up on the transmitter. All the axes of rotation are parallel, their speeds being controlled. The sighting device is located at one edge of the aircraft, being constantly sighted on a beacon beyond the end of the landing pathM while the angular speed of the aircraft along a vertical plane is measured, the sighting device also rotating about a vertical plane.

Title: Document feeding device
IPC: G06K13/14
Filed: 1965-01-11
Abstract: 1,027,952. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 11, 1965 [Feb. 17, 1964], No. 1152/65. Heading B6B. In apparatus for separating sheets from the top of a pile, wherein the sheets are not of uniform thickness and the top of the pile is therefore not horizontal, the pile is supported by two bedplates 1, 3 each of which is coupled to a pivoted driving arm 25 operable by a motor 27 through a lead-screw 29 and nut 31, whereby the angle between each bedplate and the horizontal can be varied. The sheets may be record sheets, each having thereon a narrow magnetic stripe. The bedplate 3 is secured to two side flanges 5 each journalled on a floating pin 7, and journalled at a stud 9 to a positioning rod 11 pivotal about a fixed stud 13. The bedplate 1 is secured to an angled plate 15 which, in turn, is secured to a plate 17, and the plate 17 is pivoted to the floating pins 7 at one end, and formed integral with a shaft 21 at the other end. The power arm 25 is rigidly connected at one end to the shaft 21, and at the other end is pivoted to the nut 31 which is engaged on the lead-screw 29 secured to the motor 27. The motor 27 is pivoted about a stud 33 and is operable by a manual switch, or a switch 35 controlled by the position of a friction separator roll 50. The switch 35 is automatically operated by a projection 37 secured to arms carrying the roll 50. When sheets are removed from the pile by the roll, the latter falls, the switch 35 is closed, and the motor 27 raises the pile. In the fully raised position of the bedplates 1, 3, Fig. 3 (not shown), they are horizontal and in alignment, but in the loaded position shown in Fig. 4, the plates 1, 3 are tilted to a different extent to accommodate an uneven pile, whereby at all times the top sheet of the pile is substantially horizontal. A curved guide 39 registers the front of the pile. Sheet separation, forwarding, and guiding.- The separator roll 50, Fig. 6 (not shown), is power-driven and comprises two separate rolls situated at one side of the pile which feed the top sheet between a power-driven forwarding roll 52 and a reversely-driven roll 54, which are separated by a distance equivalent to more than the thickness of one sheet: this arrangement prevents double-feed. The separated sheet is forwarded over a horizontal plate between a feed roll 56 and idler roll, then between curved guide plates 58 to a feed roll 60 and idler roll, and is finally guided downwardly by a further guide plate 61, Fig. 5 (not shown).

Title: Hop separator
IPC: C12C3/00
Filed: 1921-01-10
Abstract: 157,309. Horst Co., E. C., (Assignees of Horst, E. C.). May 2, 1914, [Convention date]. Separating on inclined endless bands; separating by falling on rebounding surfaces.-In a machine for separating hops from leaves and trash, the material passes from a'hopper B to an adjustable deflecting plate from which the greater portion of the hops rebound outwardly and fall on to a conveyer belt 7, while the remaining hops, leaves, &c. fall on to an inclined upwardly-travelling endless belt 6. The hops falling on the belt slide down and fall on to the conveyer 7, the leaves &c. being carried upwardly on the belt and finally deposited on another conveyer belt 8. Bars 10 carrying a number of spring fingers 15 extend across the upper part of the belt 6 in order to detach any hops that may adhere to the belt. Another bar 11 extends across the lower part of the belt 6 and carries a rod 16 upon which are hung a number of spring fingers 17. These fingers are free to swing outwardly to permit the passage of hops from the upper part of the belt, but are locked against movement in the opposite direction in order to prevent the passage upwards of any hops that fall upon the lower part of the belt. The hops &c. may be delivered to the hopper B from a sifting cylinder 19.

Title: Improvements in and relating to electrical transformers
IPC: H01H9/00
Filed: 1933-01-13
Abstract: 413,330. Transformers; switches. PARSONS & CO., Ltd., C. A., ROSEN, J., GILES, C., and TOPHAM, H. B., Heaton Works, Newcastle-on-Tyne. Jan. 13, 1933, No. 1250. [Class 38 (ii).] Relates to transformer tap-changing arrangements of the kind in which switches associated with successive taps are closed alternately one and two at a time, an impedance being corrected in parallel with a part of the winding between taps when the corresponding switches are closed and consists in a mechanism by which the switching operations are effected solely by energy stored in a pendulum. Tap-changing is initiated by closure of a switch 30 to start a motor 6 which, due to closure of a switch 29 by cam and roller mechanism 27, 28, is compelled to make a complete revolution. Thus, due to crank pin 9 on motor shaft engaging projection 5 on upper end of pendulum 2, the latter is swung about its pivot 4. During this movement one or other (depending on the direction of movement) of a pair of pawls 14, 15 on a carrier 11 pivotally mounted on the pendulum at 10 rides over the curved faces of teeth on the corresponding ratchet wheel 16 or 17. As the pendulum falls on disengagement of the members 5, 9, the engaged pawl operates to turn the ratchet wheels together with a cam 20 on the same shaft. The cam 20, cooperates with followers 21 spaced circumferentially at intervals correspondng to two teeth of the ratchet wheels, and adapted to operate the tap switches through spindles 22. Thus the required sequence of switch operations is produced by rotation of the cam, a fresh tap connection being established at each fall of the pendulum. Limit switches are obviated by omitting teeth on the ratchet wheels at the appropriate part of their circumference.

Abstract: 523,791. Feeding biscuits on conveyers. VICARS, Ltd., T. & T., and CROSLAND, E. M. Jan. 14, 1939, No. 1291. [Class 78 (i)] In apparatus for transporting biscuits'on a conveyer during manufacture, in which grooved shoots or dribble-trays are used to divert every other row of biscuits in the direction of the run of the belt into line with the adjacent row, thus reducing the number of rows by half, provision is made for varying the inclination of the dribble-tray to suit different conditions of working. Fig. 1 shows a belt 1 from which biscuits are stripped by a fixed plate 2 and delivered to the dribble-trays 3 which deliver between spaced boards 4 defining the lines of biscuits on the continuation of the conveyer 1. On the trays 3 the rows of biscuits are first diverted towards the right, and then diverted to the left to a greater extent by inclined surfaces. According to the invention the rotation of a shaft 12 can move the lever 11 between limiting positions defined by the stops 14, 15 thus raising or lowering the linkage 5, 8 about the axis 6 and sliding the roller 9 on the guide track 10 during the process. The upper ends of the trays 3 are attached to the central pivot of this linkage.
