Title: A gyroscopic structure
IPC: G01C21/18
Filed: 1933-07-22
Abstract: 422,577. Variable - speed gearing. ASPEREN, C. H. VAN, 314, Glenlake Avenue, Toronto, Canada. July 22, 1933, No. 20686. Convention date, July 23, 1932. [Class 80 (ii)] [See also Group XX] Gyroscopic apparatus for generating a unidirectional pulsating torque, particularly for the transmission of energy from a driving to a driven element, consists of one or more gyroscopic bodies mounted for movement simultaneously about two axes, viz. spin and turn, intersecting at an angle greater than zero, the bodies. being such that their mass is concentrated near a plane containing the axis of spin. As shown, the two bodies 1 are rotatably mounted on trunnions 30 projecting from and at right angles to a shaft 28. The latter is mounted by bearings 15, 16 in a frame 26 and is surrounded at the lower end by a sleeve 20 carrying a bevel gear 19 engaged by bevel gears 17, 18 integral with the bodies 1. The sleeve 20 at the lower end carries a worm gear 21 engaged by a self-locking worm 22 on a spindle 24 supported in the frame 26. The shaft 28 with the trunnions 30 is turned by means of the pulley 25, whereupon the gears 17, 18, meshing with the fixed gear 19 cause the bodies 1 to spin on the trunnions 30 with half the angular velocity of the shaft 28. Each body 1 exerts about an axis 6 perpendicular to both axes of spin and turn a pulsating torque which varies between a maximum when the body 1 is parallel to and zero when perpendicular to the shaft 28. The torques which are communicated to the frame 26 have the same periods in time as their axes 6 have in space. By operation of the worm 22 the gear 19 may be moved to give a transient acceleration about the axes of spin 30 causing a change of phase of the periodic torque. A similar effect may be obtained by a transient acceleration of the shaft 28. When used for the transmission of energy the pulley 25 may be replaced by a gear wheel engaging a bevel gear coupled to the driving element and the frame 26 mounted for rotation about the axis 27 and coupled to the driven element. The transient accelerations may be effected by a member arranged along the axis 27.

Patent GB-208501-A (GB)
Abstract: 208,501. Western Electric Co., Ltd., and Polinkowsky, L. Aug. 8, 1922. Drawings to Specification. Automatic and semi-automatic exchange systems.-In a revertive control system, a register controller set by the digits dialled is adapted to translate an exchange designation into a routing number in which both the number of impulses in each series and the number of impulse series may be the same as or different from those registered. The first series of impulses dialled actuates an auxiliary register which selects an exchange register upon which the second series of impulses dialled is recorded, and which, according to its setting, may control the operation of switching apparatus at one group selecting stage only over one of its brushes, or may successively control the switches at two group-selecting stages over two of its brushes. The contacts engaged by the brushes of these exchange registers are connected to a relay counting chain over a jumpering frame, in a manner to conform with any desired scheme of numbering. When the exchange registers are set to certain positions means are also provided for stopping the selecting operation of the switching apparatus at a definite switching stage before the final one, in order that a call may be routed to operators' positions reached over certain levels of the first or fourth group selectors or to a call indicator at an operators' position. The system described is identical with that described in Specification 206,578. Reference has been directed by the Comptroller to Specifications 193,694 and 194,427.

Abstract: 617,986. Packaging. PNEUMATIC SCALE CORPORATION, Ltd. July 12, 1946, No. 20933. Convention date, Dec. 11, 1945. [Class 94 (i)] [Also in Group XXX] In a method of attaching a handle comprising a length of twine and a tag to a bag, one end of the handle is placed adjacent the bag, a tag is fastened to the other extended end, the bag and the twine are moved relatively to wind the twine about the bag and dispose the tag in proximity to the bag with the extended end of the twine adjacent the first end and then both ends of the twine are fastened to the bag with the tagged end detachably fastened to the bag. As shown in Fig. 20 one end of a piece of twine 78 is held close to a tie bag 14, filled by the method and apparatus described in Specification 600,860 and a tag 84 is stapled to the other end. The bag held by grippers 30 and 32, is rotated, by the movement of a pinion 102 on a rack 318, through 360 degrees into the position shown at the left of Fig. 21. One of the grippers 30 of the succeeding bag is raised and the twine inserted by a finger 138 into a notch in a spring 136, the gripper then being lowered to its original position. The two ends of the twine on the first bag are then stapled to the bag and the twine severed at 81 as shown in Fig. 22, the free end of the twine being retracted into the position shown in Fig. 20 on the succeeding bag by the apparatus illustrated in Fig. 10 (not shown). The grippers mounted on both sides of an endless chain so that two bags are operated on at the same time receive the bags from the filling machine and eject them to a chute. The filling and tagging machines may both be operated by one prime mover and a clutch device may be incorporated so that the bags may be allowed to pass through without being tagged. A stop device may be incorporated if the chain is raised sufficiently to prevent the pinion 102 meshing with the rack 135. Details are given of the cam and link mechanisms required to carry out the various operations of fixing the tags to the twine, the handles to the bags, the removal of the bags from the grippers and the discharge of the finished bags.
