Title: Improvements in or relating to Devices for Imparting an Intermittent Movement to a Feed Member of Wrapping-machines.
Inventor: LEUMANN RICHARD
IPC: B65B35/26
Filed: 1919-07-28
Abstract: 130,604. Leumann, R. July 29, 1918, [Convention date]. Packeting by wrapping-up.-In wrapping-up machines having a pocketed member for feeding the articles, and a device for raising each article to wrapping-up mechanism and then replacing the article in a pocket, an article that is displaced on the lifting-device is prevented from striking the edges of the pocket by providing pockets of larger dimensions than the articles and by imparting a short backward movement to the feed member after each feed movement. In the arrangement shown, the feed member consists of a rotary disk 7 arranged above a stationary table 3 and formed with ribs 14 which are slightly inclined to radii, the pockets 13 between the ribs being larger than the articles c. The shaft 6 of the spider 7 is provided with a ratchet-wheel 9, engaged by a pawl 11 on an arm 10 which is connected to a camoperated link 12. The shaft 6 is also provided with a toothed wheel 8 adapted to be engaged by a relief 19 on a lever 17 which is pivoted at 15 on the base 1, and is connected to a cam-operated link 18. At each operation, an article c is placed in the pocket 13 that is at the position C, and the pawl 11 then imparts to the disk 7 a feed movement slightly greater than the angular distance between adjacent ribs 14. The lever 17 is then rocked to bring the roller 19 into contact with the wheel 8, and the lifting-device 21, 23 raises one of the articles to the wrapping-up mechanism. The pawl 11 is then retracted a short distance and the lever 17 is rocked farther to cause the roller 19 to engage the wheel 8 and move backwards for a short distance the wheel and the disk 7. The backwards movement causes the middle of the pocket that contained the raised article to be disposed under the lifting-device so that, when the article is again deposited in the pocket, the ribs do not catch the article. The lever 17 may be actuated by a spring and be arranged so that the roller 19 is in constant engagement with the wheel 8.

Abstract: 725,491. Gas holders. WIGGINS, J. H. July 6, 1953, No.18726/53. Class 54. A dry seal gas holder in which a vertically movable piston 10, Fig. 1, is arranged in a container 1 of larger diameter and in which the space between the piston and the container is sealed by a curtain-like fabric element 11 of tubular form which co-operates with cylindrical abutment surfaces on the container and piston during movement of the latter, has at least one tension band 12 attached to the element 11 and disposed circumferentially of the same, the band being shorter than the abutment surface on the container to prevent excessive permanent circumferential elongation of the element due to stretching of its fabric under gas pressure. The element is composed of a fabric core impregnated and covered with an elastic, impervious substance such as rubber while each tension band, which may be attached continuously or at intervals to the element, consists of ring-shaped elements of cable 18, Fig. 3, embedded in a easing 19 of rubber or of chains, bare cables or pre-stretched woven bands. The bands, which have a tensile strength between 1000 and 5000 lbs. per inch of width, are attached to the element by cement or mechanical fasteners each comprising a metal plate 14, Fig. 6, which is overlapped by a fabric pad 20 attached by adhesive to the element, and provided with studs 15 that project through the band to receive nuts 17. The abutment surface on the piston is formed by a series of posts 8 to provide a vertically fluted surface which prevents the element 11 from creeping circumferentially. The invention may also be applied to a gas holder of the kind described in Specification 691,664 in which an additional structure is disposed in the space between the piston and the container and connected with each of these members by a seal.

Title: Non-woven fabric comprising buds and bundles connected by highly entangled fibous areas and methods of manufacturing the same
IPC: D04H1/46
Filed: 1978-05-15
Abstract: The fleece web (60) to be patterned is guided past a first treatment station (36-38, 64) between a perforated supporting member (40) and a perforated drum casing (30, 33). At the same time, by being subjected to fluid, the fleece web (60) is provided with a first pattern, in that the fibres are ordered by the specific position of the perforation of the member (40) and of the casing (30, 33) in order to form the first pattern. After this first treatment, the supporting member (40), together with the patterned fleece web (60), is removed (B) from the drum casing (30, 33) and is then reapplied (C) to the drum casing. This produces a repeat shift between the perforations of the member (40) and casing (30, 33), so that, in a subsequent second treatment station (36a-38a, 65), the fleece web (60), by being subjected to fluid, receives, as a result of the other position of the perforations in relation to one another, a second pattern which, on account of the repeat shift, is different from the first pattern and which is superposed on the latter in the desired way. Further places for the repeat shift and further treatment stations can also be present. <IMAGE>

Title: Improvements in and relating to a process for cleaving and converting of heavy hydro-carbons into lower boiling specifically lighter products
IPC: C10G11/04
Filed: 1920-07-08
Abstract: 147,648. Cordes, C., (Assignee of Thiele, F. C.). July 28, 1914, [Convention date]. Hydrocarbons, cracking.-Heavy hydrocarbons, such as heavy raw mineral oils or mineral oil residues, are converted into lower-boiling products by distilling them with a hydrosilicate, such as that found in the oligocene formation in South Georgia or Florida, which acts as a catalyst. The oil is distilled in a boiler which contains the coarsely-crushed hydrosilicate, at a slowly-rising temperature. When condensates having .78-.80 sp. gr. are obtained, dry steam is admitted and the temperature regulated so that the temperature in the dome of the boiler does not exceed 270‹ C. The distillation is stopped when condensates of .86 sp. gr. are obtained, and the residue which is suitable for use of lubricating-oil is discharged. The hydrosilicate after repeated use is regenerated by washing with petrol, treating with steam, and heating. The residues, which are stated to be free from asphalt, are treated in a second boiler to obtain residues of different viscosity and distillates of petrol and gas-oil, The residues may be first cooled to separate paraffin wax.

Abstract: 533,289. Frequency modulation. CORK, E. C., and PAWSEY, J. L. July 6, 1939, No. 19642. [Classes 40 (iii) and 40 (v)] An unbalanced condenser microphone or like signal device is associated for frequency modulation with a balanced oscillator circuit in such manner that the balance of the circuit with respect to earth is not disturbed. In Fig. 1 the unbalanced microphone circuit 7 is coupled by a transformer 5 to the tuned and balanced output circuit 4 of the push-pull oscillator 1. For shorter waves the tuned grid and plate circuits of the oscillator are in the form of Lechers conductors 10, 11 bridged at 12, and the microphone 7 is connected to one end of a concentric line 5a, the other end of which is connected by condensers 8, 9 to the anode pair 10, 11. The line 5a at the end remote from the microphone is surrounded by a cylinder 56 one quarter-wave in length, earthed at the anode end, and connected to the outer conductor of the line 5a at its other end. In Fig. 3, the unbalanced microphone circuit 7 is balanced by an output feeder 16. The microphone line 15 extends into the hollow anode conductor 10, and its inner line is connected to the opposite anode conductor 11. The output feeder is associated with the conductors 10, 11 in the opposite sense. Both outer conductors 15, 16 are gapped and bridged by a condenser 19 for blocking D.C. voltage. Coarse tuning may be effected by sliding the bridge 12, and fine tuning by slidable rods supported in sleeves on the outside of the conductors 10, 11. The lines 15, 16 may be situated in line with the anode conductors 10, 11, Fig. 3a (not shown). In Fig. 4, a half wave length concentric conductor 20 is connected between the anode conductors 21, 22, and the microphone line 15 and output line 16 have their outer members connected to opposite ends of the concentric line 20, and their inner members connected through blocking condensers 8, 9 to the adjacent anode conductors 21, 22. High tension is applied to voltage nodes of the conductors 21, 22 through chokes 23.
