Title: Twin fluke anchor
IPC: B63B21/44
Filed: 1972-09-07
Abstract: 1371130 Anchors BRUNSWICK CORP 7 Sept 1972 [7 Sept 1971] 41585/72 Heading B7S The shank 30 of a twin fluke anchor carries stops 36 which engage the edges of crown side walls 26 and 34 to limit angular movement of the shank relative to the flukes. Thus compression forces rather than shearing forces are generated in the crown side walls so that it is possible to use lightweight materials in the anchor construction. The anchor may have various forms in which flat stop surfaces engage flat side wall edges; however, the stops may be of cylindrical form, Fig. 6 (not shown), in which case they engage correspondingly curved regions of the crown side walls.

Abstract: 1,059,130. Shoots; endless conveyers. SPEAKER SORTATION SYSTEMS Inc. Nov. 4, 1963, No. 43524/63. Headings B8A and B8S. A mail bag sorting system comprises an incoming feed belt 1 carrying unsorted mail bags 2 with identification tags 3 secured to bag closing ropes 4. The mail bags 2 are diverted by a diverter 6 on to a storage shoot 5. A separator 16 diverts the mail bags into a pair of loading devices 7 (one only shown). An endless belt 15 driven by a motor 23 carries each mail bag 2 to an orienting table assembly 9. When a mail bag 2 interrupts a light beam from a lamp 30 to a photo-electric cell 28 the motor 23 is stopped. The assembly 9 includes a slanting table 24 which can be adjusted by a foot-operated pedal controlling a jack 37 so that mail bags 2 falling on to the table 24 generally stop, but can be slid down with little effort by an operator. If a mail bag 2 starts to slide under its own weight, or if the operator desires to stop the movement of a mail bag 2 once started, a slight backward push suffices to stop it. The operator reads the identification tag 3 of each mail bag 2 as it arrives on the table 24 and depresses an appropriate destination key 33 on a keyboard 10 so that a particular tray 11 on a conveyer 8 moving in an endless path dumps the mail bag at the required point (not shown). The conveyer 8 is driven in synchronism with an interconnected stop 65 and bucket 27 which are actuated by an air cylinder 57. The stop 65 is operative when the bucket 27 is pivoted about an axis 44 to dump a mail bag 2 into a tray 11 (Fig. 3) and inoperative when a mail bag is to be slid off the table 24 into the bucket 27 (Fig. 4, full lines).

A jib crane safe load indicator comprises a body portion 1 mounted on the boom stay pin 30 within which a spring or weight-loaded lever 2 pivoted at 33 closes contacts 4 when overload occurs. Contacts 4a may be provided which remain closed when normal loads are involved to light an indicator light. A force dependent on the load is applied to the lever 2 by a movable roller 5 actuated by a bell-crank 6. The derricking rope passes over a pulley 14 and a force dependent on the load tension therein is transmitted by plates 12 attached to eccentric portions 42 of a pin mounted in the body 1 through levers 10, 9 to the bell-crank 6. The effective force applied to the lever 2 in opposition to a spring 3 to close the contact 4 is varied according to the jib position and other conditions by moving the roller 5 which is connected by a linkage 16, 17, 19 to a cam lever 20 pivoted at 31 to a bracket of the body portion 1. Two cam followers 24, 24a (not shown) corresponding to the unblocked and blocked condition of the crane engage a cam 25 mounted externally of the indicator on a fixed part of the crane. When the crane is blocked the cam lever 21 is retracted to the position 21R where it may close a switch 27 to indicate that the blocked cam follower is effective. Positioning the cams externally of the indicator body allows ready replacement when the crane conditions alter and allows the effective cam to be readily identified. Specification 723,070 is referred to.

Title: Induction pickoff device
IPC: G01B7/31
Filed: 1962-11-28
Abstract: 971, 613. Inductive pick off-devices for gyroscopes. NORTH AMERICAN AVIATION Inc. Nov. 28, 1962 [Dec. 8, 1961], No. 45013/62. Headings G1C and G1N. An inductive pick off for sensing the angular deviation of a gyro motor about two perpendicular horizontal axes utilizes the distortion of the flux field produced by an energizing winding, due to the armature reaction field associated with the eddy currents in the rotor. As shown (Fig. 1), the rotor comprises a sphere 14 of conductive material supported in a spherical bearing, and driven about a vertical axis by an A.C.-energized external coil 16. The pick off assembly is mounted centrally at the top of the casing 12 coaxially with the rotor spin axis 50 (Figs. 2, 3), and comprises a circular energizing coil 29 and two pairs of diametrically located secondary coils 30, 31 defining a horizontal X axis, and 32, 33 defining a horizontal Y axis. The coils 29-33 are wound on the split end of a magnetic core 23, and the coils of each pair are connected in series opposition. The magnetic field associated with eddy currents produced in the rotor 14 distort the main magnetic field produced by winding 29 in a manner which is normally symmetrical with respect to coils 30, 31 and 32, 33, whereby the induced EMF's in each coil of a pair are equal, giving zero resultant output from the series connection. If the casing 12 is displaced about a horizontal axis, the rotor spin axis 50 is no longer symmetrically located with respect to the coils 30-33, and an output signal is obtained from coils 30, 31 whose magnitude and phase sense is indicative of the X component of displacement, and a signal from coils 32, 33 indicates the Y component of displacement. The pick off signals may be fed to a servomotor for repositioning the casing 12 relative to the rotor spin axis.
