Title: Improved method of preventing slipping of threads in textile fabrics
IPC: D06M23/06
Filed: 1962-04-02
Abstract: The slippage of threads in fabrics made of intersecting threads and produced, for example, by knitting, weaving, crochet work or netting, is prevented by applying to each individual thread of the fabric at selected intersections thereof with other threads of the fabric, discrete quantities of a bonding agent to produce spaced welds, in such a manner that the number of unbonded intersections of the individual thread with other threads of the fabric between any one weld of the individual thread with another thread and the next following weld of the same individual thread with a different thread of the fabric is normally at least one and does not exceed ten so that normally intersections of threads immediately adjacent to any one weld have no bonding agent applied thereto.  The treatment may be applied to the whole area of the fabric or to a limited area or areas only in the fabric.  The bonding agent may be applied by screen printing in a regular pattern constituting a roster, i.e. a pattern of spots placed on the intersections of a network of two series of virtual lines or generatrices which are parallel and equidistant, the lines of the two series intersecting, for instance, at right angles and being angularly inclined to the general direction followed by the threads of the fabric.  The process is particularly applicable to preventing laddering of stockings.

Title: Improvements in and relating to automatic cartridge loading machines
IPC: F42B33/02
Filed: 1931-04-29
Abstract: 369,450. Delivering measured quantities of powder. GILLERN, (GEB. POLTE), KATHARINA, FREIFRAU v., GILLERN, ARNULF, FREIHERR v., NATHUSUIS, (GEB. POLTE), M., and NATHUSUIS, M., (trading as POLTE, [Firm of]), Poltestrasse, and OESTERLIN, H., both in Magdeburg, Germany. April 29, 1931, No. 12620. [Class 106 (v).] Preliminary main and subsequent small additional supplies of powder are fed into cartridges by a device comprising a container which retains the powder under vacuum and which, on the pressure rising, delivers the powder to the cartridge case. According to one construction, powder from a supply passage is delivered to a container 26, Fig. 8, the capacity of which is equal to the quantity of powder to be delivered to one cartridge. Above the passage and container, and separated therefrom by sieves 34a, 34, are respectively provided chambers 31, 32, each connected, through openings 36, with a pipe 37 leading to a suction pump. An opening 41, in another chamber above the container, is in communication with the atmosphere or with a supply of gas. The openings 36 are fitted with spring- controlled valves 38, 39, which are actuated by cams 40. When the valve 38 is open and the valve 39 is closed the powder is prevented from flowing through the narrow inlet 29 of the container by the vacuum in the chamber 31. When the positions of the valves are reversed the container fills, but the vacuum in the chamber 32 prevents the powder from escaping through the narrow outlet 28. The measured quantity is delivered through this outlet when the positions of the valves are again reversed. The outlet 28 is covered by a perforated flap 44 during the initial stages of the filling operation. The capacity of the container may be varied by operating a non-circular disc 45. In a modification, the quantity of powder delivered by a container 3, Fig. 1, is regulated by the time during which the pressure therein is increased. To the container is secured a pipe 9 in which slides a pipe 10, the pipes being provided with slots 14a, 14b, 15a, 15b which, when in register, admit air under atmospheric pressure to the container. The pipe 10 is spring-controlled and is connected to one arm of a pivoted lever 11 the other arm of which is actuated by cam surfaces provided on a rotating disc 12. The slots 14a, 14b are relatively large and are brought into register at every half-revolution of the disc 12. The slots 15a, 15b are small and are brought into register several times during a half-revolution of the disc. Each time that air is admitted, the pressure in the container 3 rises and a quantity of powder is expelled through the outlet 7. Adjustable slotted rings are arranged around the slots whereby their effective area, and thus the quantity of powder delivered, may be adjusted. The Specification also describes other constructions embodying the same principle.

Title: Conveyer transfer mechanism
IPC: B65G47/61
Filed: 1958-04-22
Abstract: 854,436. Endless conveyers. RADIO STEEL & MFG. CO. April 22, 1958 [May 20, 1957], No. 12798/58. Class 78(1). Articles are transferred from one conveyer to another travelling at a different speed, e.g. from a conveyer 8, Fig. 2, to a conveyer 6, by a series of extensible arms 34 provided with loadengaging hooks 38 which are mounted on a rotatable disc 22 and are extended and retracted in timed relationship with the conveyers. The disc 22, Fig. 1, is secured rigidly to a sprocketwheel 18 which is mounted rotatably on a fixed shaft 14 and is driven by engagement with load carriers 88 depending from the conveyer 8. Each arm 34 is pivoted at 36 to a bracket 37 depending from the disc 22 and is connected at its end to a plate 40, Fig. 3, from which depend shafts 46 carrying rollers 48. These rollers engage the rail 54 of a cam-guide-plate 50 and the upper surface of this plate supports rollers 42 mounted on the underside of the plate 40. The hub 58 of a sprocket-wheel 56 is mounted rotatably on the shaft 14. A collar 64 secured to the hub has a series of rods 66 pivotally connected to it. The outer ends 70 of the rods are pivoted. to vertically slidable bars 72 which end in forked members 74. The bars 72 move in guides 76 secured to the rim of the sprocket 56. Each rod 66 has a depending part 80 which engages a fixed cam surface 78. A fixed guide-strip 84 retains the shanks 90 of the carriers 88 between it and the sprocket 56. The hook 94 of a carrier 88 engages the upper cross-member 98, Fig. 5, of a double eyelet 96, the depending shank 100 of which ends in a hook engaging the load. At the beginning of a transfer a hook 38 at the end of an arm 34 engages the cross-member 102 of an eyelet 96. As the rollers at the end of the arm move along the cam track 50, the arm rises and lifts the eyelet from the hook 94. Further movement along the track takes the carrier away from the conveyer 8 and towards the conveyer 6. As the arn is extended, the eyelet is carried towards a hook 94 of the conveyer 6 until the hook is in position to engage the crossmember 98. Further movement of the arm along the cam-track causes it to descend slightly to deposit the eyelet on the hook and then to retract to withdraw the hook 38 from the eyelet. Means, which is synchronized with the movements of the conveyers 6, 8, is provided for engaging and steadying the load carriers as they arrive at the transfer station.

Title: Method of preparation of linear superpolyesters
IPC: C08G63/40
Filed: 1949-05-19
Abstract: In the production of superpolyesters suitable for drawing into fibres by condensation of aromatic dibasic acid chlorides and glycols, e.g. terephthaloyl chloride or isophthalylchloride and tetramethylene glycol, as described in Specification 630,992, decomposition of the glycol at the high temperatures used to complete the reaction is avoided by employing only 85-99 per cent of the equivalent proportions of the glycol and condensing the linear polyester so formed with an amount, approximately equivalent to the excess of acid chloride, of a different glycol which has more than four atoms in the chain between the hydroxyl groups, e.g. pentamethylene-, hexamethylene-, decamethylene-, diethylene-, triethylene-, tetraethylene-glycols, di-(beta-hydroxyethyl) sulphide, 3,31-dihydroxy dipropyl sulphide, 3,6-dithia-1,8-dihydroxy octane and 1,4-cyclohexane diol.  The reaction is preferably carried out by introducing incremental amounts of the tetramethylene glycol with the inert gas used to sweep the reaction vessel containing the acid chloride, until a polymer of the required viscosity is obtained and then introducing the higher molecular weight glycol also in incremental amounts with further measurements of viscosity. Purification of the tetramethylene glycol used is obtained by crystallization from dry acetone and ether while the acid chloride is purified by recrystallization from dry petroleum ether.  In example (1) 16 parts tetramethylene glycol and 37.5 parts terephthaloyl chloride were reacted for 95 minutes in a continuous stream of nitrogen, the temperature rising to 218 DEG  C.  The reaction mass was then heated under vacuum to remove gas bubbles, when a melt of viscosity 2.7 poise was obtained.  2.5 parts decamethylene glycol were then added over a period of 210 minutes while heating, whereupon a polymer of viscosity 1500 poise was obtained.  Specification 655,377 is referred to.
