Abstract: 1293788 Filling upholstery; sleeping bags;  bedspreads CELANESE CORP 4 Aug 1971 [5 Aug 1970] 36538/71 Headings A4G, A4M A4S [Also in Divisions A3 and D1] In an apparatus for filling open ended containers to form a padded article, e.g. sleeping bag, bedspread, or quilted housecoat, a tow or bundle of crimped, continuous filaments 12(a-e) is fed into a container 50, shown as part of a sleeping bag 46, by a current of air through Venturi tubes 38 in which the bundle 12 is opened to render it bulky, the flow is interrupted when the desired amount has been filled into the container 50 and at the same time the bundle 12 is severed near the entrance to the container. The bundles 12a-e are fed through a banding jet 14 and over a series of rollers 20-36 e.g. as in Specification 1001813 so that the crimps are no longer in registry when they enter the Venturis 38. A hot wire 54 is downwardly displaceable adjacent the discharge ends of the Venturis 38 to sever the filaments when the containers have been filled. The filling passes from the Venturis 38 into tubes 42 located in the containers 50 which are located on a table 44 which is progressively displaced away from the Venturis as the containers 50 are being filled. The interruption of the feed may be effected by cutting off the air supply to the Venturis 38. The movement of the table 44 and the cut-off of air supply may be controlled by a meter 52 set to measure either time or linear distance travelled by the filaments. Blades or shears may be used as alternative to the hot wire 54. The cycle of operations may be controlled either automatically or manually. As an alternative to the roller assembly 20-36, the crimped tows may be deregistered by tension rolls or air blasts.

Title: Improvements in electromagnetic relays
IPC: H01H51/10
Filed: 1934-12-22
Abstract: 436,619. Light current relays and electromagnetic switches. RICHTER, M. B., (trading as TELEFON FABRIK AUTOMATIC VED M. B. RICHTER), 7, Amaliegade, Copenhagen) Dec. 22, 1934, Nos. 36829 and 36830. Convention dates, Dec. 22, 1933 and Aug. 10, 1934. [Class 38 (v)] An electromagnetic telephone relay in which the contacts are acted upon by a member which is held by a locking pawl in a latched position after an attraction of the armature and which member is returned to the unlatched position by spring action on the next attraction of the armature is provided on this member with an arm which co-operates with the armature to move the member to the latched position on the first attraction of the armature and to release the pawl upon the second attraction of the armature, the position of the arm with respect to the armature being determined by the position of the pawl when in the released and the latched position. As shown in Figs. 4-6 the armature 17 has a springy angleshaped metal plate 22 secured to it near its pivotal point (not shown), the bent-over portion of the member 22 supporting a latching member 26 and a releasing arm 24 on which bear blade springs 31, 32. The member 22 bears against a fixed stop 29 in the unattracted position of the armature and a contact-operating projection 23 engages a contact spring 20<a> in this position. On energization of the electromagnet 18 the armature 17 is attracted and causes a groove 25 in an operating projection to engage the end of the arm 24 and drive down also the springy member 23. In the fully attracted position, Fig. 5, the shaped end of the latching member 26 moves behind a fixed latching shoulder 27 so that on de-energization of the electromagnet the armature returns partially but the springy member 22 remains held by the latching member, Fig. 6. During this partial return of the armature, however, the end of the operating member 24 is released from the groove 24 and the movement of the armature with relation to the springy member 22 causes the pawl 26 and the operating member 24 to be swung slightly to the right. Thus, on a succeeding energization, the end of the member 24 bears on the inclined end face of the operating projection so that the latching member is moved to the right and released from the latching shoulder 27, the springy member immediately returning to its initial position. As shown, the sequence of contact operation during the successive stages of operation of the relay is : contact x closed and contact y open, both contacts x and y open, and contact x open and contact y closed. In a modified arrangement a cam is provided which is operated by the movements of the member 23 to ensure correct sequence of operation of the contacts. The energizing circuit of the relay may be completed over its controlled contacts the coil circuit being completed over different contacts during the various stages of its operation.
