Patent FR-1494989-A (FR)
IPC: B29C65/08
Filed: 1966-08-05
Granted: 1967-09-15
Abstract: 1,193,838. Seaming non-metallic sheet material. REALISATIONS ULTRASONIQUES. 28 July, 1967 [5 Aug., 1966], No. 34925/67. Heading B5K. An ultrasonic welding device is provided with means for displacing a welding head 5 towards parts 1, 2 to be welded and to determine its position at the beginning of its contact with the part 1 and means for limiting to a predetermined amount the further displacement of the head 5 in the direction towards the part 1 from the said position. In one embodiment, Fig. 1, a plastics cover 1 is welded on to a plastics box 2 by the head 5 carried by an ultrasonically vibratable member 4 connected to a magnetostrictive transducer 6. The member 4 is supported at a node of vibration by a flange 7 fixed to a tubular member 8 having a lower flange 9 which carries an electromagnet 11. The member 8 is displaceable through a ball-bearing slide 10. A dial indicator 13 is provided with a vertically displaceable rod 14 carrying a blade 14 of soft magnetic material attractable by the electromagnet 11 when the latter is excited. In operation, the position of an electric contact 20 is preset so that a needle 21 touches it when the rod 14 has undergone a predetermined displacement. The member 8 is lowered and the flange 9 closes a microswitch 19 and, after a time delay, determined by a relay 17, the latter closes a contact 16 so that the blade 15 is attracted by the electromagnet 11. Simultaneously, the head 5 is ultrasonically vibrated. During the welding, the head 5 continues to move slightly downwards until the needle 21 touches the contact 20 and the ultrasonic vibrations are immediately cut-off by a circuit 22 which after a time predetermined by a timing mechanism therein moves the member 8 upwardly towards its rest position. In another embodiment (not shown), the dial indicator and the electromagnet are omitted and the member 8 and the support 3 are each provided with an adjustable stop. The ultrasonic vibrations are started when the welding head contacts the upper part to be welded and are arrested when the stops contact each other. In a further embodiment (not shown), the means to cut off the ultrasonic vibrations when the two stops contact each other is omitted and the vibrations are produced during a time determined by a timing mechanism using fixed stops to limit the penetration of the welding head.

Abstract: 570,517. Indicators for displaying variable information. VAUCHER, E. Jan. 7, 1944, No. 370. [Class 118 (i)] [Also in Group XV] An indicating device more particularly for use with index cards comprises a number of slidable elements employed in conjunction with inscriptions on the card &c., each element being provided with an aperture to receive a suitable actuating implement for moving them singly into and out of operative position, the major portions of the elements being covered in their inoperative positions. In one form, Fig. 1, the elements d which are made of celluloid or other transparent material are slidable between staples a securing two spaced strips b, c to the edge of an index card k. The rim g of a perforation f in each element projects into a vertical slot e in the strips c to limit the movement of the element, which is operated so as to expose the inscription thereon by the insertion of a pencil point in the perforation. Similar inscriptions are provided on the exposed part of the strips b. The elements are coloured or otherwise marked so as to be readily distinguishable. As applied to a card for indicating quantities of items in stock, the slots e extend almost the full depth of the card and the indicating elements each have a mark thereon co-operating with a scale on the card so as to indicate the quantity of each item.

Title: Improvements in the manufacture and production of ammonium sulphate nitrate stable for storage
IPC: C05C1/02
Filed: 1931-01-09
Abstract: Ammonium sulphate-nitrate is rendered stable for storage, particularly for the fertilizer industry, by adding thereto urea and non-deliquescent salts which in a dehydrated state are capable of combining with water of crystallization.  Salts of magnesium, aluminium, iron in the ferrous or ferric state and Glauber's salt are specified.  The salts may be used in the anhydrous or partially or completely hydrated condition.  Preferably, about one part urea per three parts of salt is employed, \ba1/4\be-10 per cent by weight of urea being used.  The mixture may be added to the ammonia sulphate-nitrate at any time during its preparation. In examples, urea is added to a solution of ferrous sulphate, and the mixture added to an agitated mixture of ammonium sulphate and nitrate; hydrated aluminium sulphate or dehydrated magnesium nitrate and urea are added to ammonium sulphate-nitrate; a hot solution of Glauber's salt and urea is sprayed on to ammonium sulphate-nitrate with mixing. The mass is dried in some cases, for instance, at 100 DEG  C.  A statement of prior art refers to the use separately of urea and non-deliquescent salts capable of combining with water of crystallization, for example, magnesium salts.ALSO:Ammonium sulphate-nitrate is rendered stable for storage, particularly for the fertilizer industry, by adding thereto urea and non-deliquescent salts which in a dehydrated state are capable of combining with water of crystallization.

Title: Improvements in or relating to corn popping
IPC: A23L1/18
Filed: 1956-01-10
Abstract: 827,652. Popping corn. GENERAL FOODS CORPORATION. Jan. 10, 1956 [Jan. 11, 1955], No. 913/56. Class 58. In popping corn, a blower 16 blows a gas such as air through a heating chamber 17 and a pipe 19 into the lower part of the narrow portion 9 of a tubular popping device. Corn is fed from a hopper 20 by a worm conveyer 22 into the upper part of the portion 9 and carried by an ascending current of heated gas into a wider portion 10 of the popping device. The popping device may comprise a still wider upper portion 12, as shown, or an upper portion having a diameter smaller than that of the portion 10 but larger than that of the portion 9. The current of gas carries popped corn 23 out of the popping device into a housing 6, wherein it is deflected downwards and guided by a wall 25 and, if desired, a wall 26, preferably funnel-shaped, into a receptacle 24. Corn which fails to pop collects in the portion 10 and, when the velocity of the gas is reduced, falls into a trap 14, which may be detachable and/or fitted with a door 15. The housing 6 is, preferably, surrounded by a housing 7 providing a heat-insulating space 8, which may be filled with a gas such as air or evacuated. Preferably, both housings 6 and 7 are made of transparent glass or plastic material and have domed tops, as shown. When the wall 26 is provided, heated air is returned to the blower by connecting its suction intake 28 to the passage between the walls 25 and 26. When no wall 26 is provided, a circular portion of the wall 25 may take the form of a circular screen, which is connected to the suction intake of the blower. The cross-section of the popping device is, preferably, circular, but it may be elliptical, rectangular or square.
