Filed: 1928-05-04
Abstract: 320,077. Shane, J. S. May 4, 1928. Right to Patent relinquished. Balls.-A toy balloon 4 is enclosed in a light protective casing 1 of linen or other material. The casing is made up from segments, preferably six in number, by sewing their edges together so as to make the seams inwardly smooth. A slit 3 is formed in one of the cover sections, the balloon being inserted through the slit and access to the inflating neck 5 of the balloon being obtained by means of the slit. A flexible flap 6, formed from a strip of cloth, rubber, &c., folded upon itself and having slits coinciding with the slit in the casing is secured to the casing by sewing round the edges of the slits only. After the balloon is inflated, the neck is twisted and turned back through the slit, the flap 6 curling round it and assisting to maintain the inflation of the balloon. The cover may be formed by first making two halves of circular shape from the segments and then sewing these together round their margins. The segments may be made of different colours, and the cuts in the cloth may be made obliquely to the direction of the threads of the cloth.

Abstract: 538,582. Electrically-released switches. CRABTREE & CO., Ltd., J. A., and McLOUGHLIN, H. F. Aug. 22, 1940, No. 13328. [Class 38 (v)] A no-volt release, applicable to the switchgear described in Specifications 533,166 and 533,167, in which a spindle h can be operated by a handle to an " on " position on either side of a neutral " ofF position, from either of which, " on " positions it can be released by a thermallysensitive element operating a trip bar, comprises a winding j energized when either contacts first close, and an armature I which is pivoted at l<1> and urged against the core k by a spring m. The final movement of the spindle h causes a stud n to engage a roller o, thereby separating one part p= of a two-part carrier p from the other part p<1> and retaining it agaihst the action of a spring q, the other carrier-part being mounted on pivot s and held by engagement of a lug p<4> thereon over the armature so long as the latter is retained by the magnet k. When the armature is released, spring q causes it to move so that a bracket t thereon engages an L-shaped bracket u and displaces a roller v to produce tripping. The resilient movable contacts cause the parts to return to normal after tripping, and spring m returns the armature into engagement with the core. A separate two-part carrier is provided for each direction of handle-movement.

Abstract: 1,076,361. Clocks and watches. PORTESCAP S.A. March 31, 1965 (April 10, 1964], No. 13542/65. Heading G3T. A clock having an alarm actuating switch 6, 7 closed by a trip lever 3, and wherein the setting of the alarm is marked on a ring 13 and displayed through a window 16 having an index mark, is characterized in that this window is provided with a movable protective glass 17 constituting a control push-button for stopping the alarm. Lever 3 is tripped once in twenty-four hours by a cam 1 driven in known manner from hour wheel 8 through a differential 9, and moves contact 6. The alarm is set through a knob on a shaft 10 having a pinion 11 geared through a wheel 12 to the differential 9. The ring 13 is engaged by a gear 19 on shaft 10. Ring 13 is rotatably supported by a plate 25 having two portions 26, 27 of different diameters against the larger of which, 27, the ring is biased by a spring 29. This permits movement of ring 13 along a diameter by depression of glass 17 to rotate a stop lever 21. This lever has a pin 23 which opens the second contact 24. Operation of the stop until lever 3 has been tripped is prevented by an arm 3c engaging pin 23. Stop lever 21 is returned by the arm 3c as lever 3 rides on to the cam 1.

Abstract: 403,622. Control of D.C. motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.- (Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) May 12, 1932, No. 13730. Convention date, May 15, 1931. [Class 38 (iii).] Varying E.M.F.-In a Ward-Leonard system, a switch is frictionally operated by the motor to one of two circuit-closing limit positions, according to the direction of rotation to enable reverse excitation to be applied to the generator for compensating for the remanence when the former excitation has been removed. When a control switch g is moved to one of its extreme positions, one of the fields l, r of an exciter e is energized to supply the field of a Ward-Leonard generator s supplying a rudder'motor m, which runs in the appropriate direction. The motor frictionally operates a switch k to one of its extreme positions, so that when the switch g is restored to its central position to stop the motor m, the field of the exciter and, therefore, the generator is reversed, and the motor begins to run in the reverse direction. Directly it carries the switch k into the other extreme position, however, the generator field is again reversed, and soon the motor comes to rest with the switch k in its mid-position. The switch k has intermediate positions between the extreme and midpositions in which resistances ware included in the circuit. In a modification the central contacts of the switch g are omitted and a small reverse excitation, sufficient to compensate the residual magnetism, is provided by means of a circuit including resistance y, when the switch k is in either of its extreme positions.

Abstract: 461,056. Binders for loose sheets. BANKERS BOX CO. May 16, 1936, No. 13971. Convention date, May 31, 1935. [Class 146 (i)] A device for permanently binding loose sheets comprises a tubular member 14 having a sleeve mounted therein, the interior of which is roughened or serrated for engagement by a split spring-ring 12 carried by a headed pin 5. The sleeve may take the form of a close-coiled spring 18 secured against inturned ends 17 on the member 14 by a headed stud 15. A reduced tapered part 9 on the pin 5 carries the split spring-ring 12 which allows the pin to be pushed into the member 14 but is forced by the part 9 into engagement with the spring 18 when withdrawal of the pin 5 is attempted, and prevents separation of the members 5, 14. In a modification, the reduced part 9 is parallel-sided and carries a split dished washer. In place of the coiled spring 18, an ordinary sleeve may be employed, its surface having continuous or discontinuous corrugations or indentations formed for engagement by the split spring-ring. The stud 15 may have an enlarged threaded extension forming a shoulder around which the member 14 and the sleeve are pressed into contact with the stud to secure it.

By regular is meant a field whose value either changes linearly with axial distance between the ends of the arrangement, or is uniform in the axial direction; the latter may be provided as shown by having all the magnets of similar dimensions but disposed axially closer to each other at the centre than at the ends of the arrangement, or, not shown, by using axially equispaced magnets whose axial lengths and/or external diameters are greater at the centre than at the ends. The arrangement also provides within limits a uniform radial field, and the magnets may be of the material described in Specification 708,127. Specification 576,369 also is referred to.
