Title: Automatic shuttle change motion for weaving looms
IPC: D03D45/34
Filed: 1929-09-09
Abstract: 344,805. Looms with automatic weft replenishment. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES, Mulhouse, Haut-Rhin, France. Sept. 9, 1929, No. 27320. Convention date, March 7. [Classes 142 (i) and 142 (iii).] The loom is of the kind wherein, upon exhaustion of weft, the loom is stopped, a separate shuttlechanging mechanism is put in operation, and then the loom is restarted. The driving pulley 1 and an integral pinion 19 are loose on the main shaft 3 which is geared by reduction gearing 4, 5 through the cam shaft 6 to the crank shaft 7. The shaft 3 carries a brake 8 and a friction clutch 2 co-operating with a clutch part on the pulley 1. The pinion 19 drives the shuttle-changing cams 17, 17a, 17b through gearing 20, 21, 22 and a clutch 23, 34. On exhaustion of the weft the lever 10 is moved anticlockwise depressing the rod 11 from a catch and pulling down the rod 60 thus releasing the catch 15 and allowing the spring 16 to apply the brake 8, 9. Simultaneously the rods 11, 12 are moved to the left by the strong spring 11a and the lever 13 moved by the stop 12a to disengage the clutch 2. The lever 25 at the same time lifts the catch 26 and allows the spring 27 to engage the clutch 23, 24. The now rotating cam 17 through levers 30, 31, 33, 35 lifts the shuttle box side 28 and ejects the empty shuttle, and through the lever 38 and rods 37, 39 releases the brake and re-sets the rods 11, 12, but the clutch 2 is kept out by the catch 41. The cam 17a through the levers 43, 44, 45a first moves the shuttle-carrier 42 against the catch 47 to release a shuttle 48 and then allows the spring 42a to transfer the shuttle into the box. Finally the cam 17b through the levers 50, 51, 52 lifts the catch 41 to restart the loom and disengage the clutch 23, 24, the lever 28a being again engaged by its catch 26. The ejected empty shuttle normally hits a plate 54 and displaces a catch 55, 56 which is retained in its displaced position by another spring catch 58, until the stop 59 on the transferrer trips the catch 58. Should the empty shuttle be not properly ejected the catch 55 will engage the stop 59 and prevent shuttle replenishment.

Title: Improvements in and relating to sheet feeding devices
IPC: B65H29/12
Filed: 1932-10-01
Abstract: 394,192. Feeding sheets. PACKAGE MACHINERY CO., 132, Birnie Avenue, Springfield, Massachusetts, U.S.A. Oct. 1, 1932, No. 27333. Convention date, Oct. 28, 1931. [Class 100 (i).] A sheet-feeding apparatus, which is especially applicable for feeding sheets cut to an adjustable length from a web to a wrapping-machine, is constructed with a continuously moving conveyer comprising two spaced belts 61, Figs. 4 and 5, and a second conveyer 82 formed with one or more pads 86 positioned to press the leading edge only of a sheet against the belts 61 to cause the sheet to be positioned against a registering stop 93. The sheet is cut from a web 16 fed from a roll 13 over a'tensioning- roller 19, and advanced intermittently to an adjustable extent by means of a driven roller 17 engaged by a spring-pressed roller 22 covered with cork and mounted so that it can be raised by a cam when a new roll is to be introduced. The roller 17 is driven by a ball clutch operated from a shaft 36, Fig. 2, by means of a crank 35, a bell-crank lever 31 having an adjustable connection with a rack 27 which oscillates the driving member of the clutch. The shaft 18 of the roller 17 is fitted with a brake to prevent overrunning, and the shaft 18 is given a slight reverse movement to free the web from the knife 40 after this has been operated by an oscillating arm 41, the reverse being operated by a lever on the shaft 42 of the arm 41 through a pin-and-slot connection with an extension of the brake. Below the belts 61 are three shorter belts 60, which are offset with respect to the belts 61 as shown in Fig. 5, so that the web is not gripped positively by the belts 60, 61, but is acted on with sufficient friction to keep the leading end of the paper extended beyond the knife. The spring-pressed pads 86 press the leading end of the web against the belts 61 prior to the action of the knife 40, and the pads 86 reach bars 78 under which the belts 61 pass so as to grip the leading edge tightly just after the sheet is severed. The bars 78 are adjustable longitudinally so as to adjust the feed for sheets of different lengths, and pulleys 76, 77 for the belts 61, and the stop 93 are adjustable with the bars 78. When the cut sheet passes beyond the tapes 60, its under surface is supported by fixed guides.

Title: A process of printing textile materials with vat and sulphur dyestuffs
Inventor: CONRAD JOHANNES
Filed: 1958-08-27
Abstract: In the printing of textile materials with vat or sulphur dyestuffs by a two-stage process wherein the textile is printed with the dyestuff in the first stage and then, in the second stage, is treated with a solution of a reducing agent and finally heat-treated, the reducing agent employed is an alkali-metal or ammonium salt of a straight- or branched-chain-hydroxyalkyl p  sulphinic acid with 2 to 4 carbon atoms.  Specified reducing agents are the alkali-metal and ammonium salts of hydroxyethane-, hydroxy-n-propane-, hydroxy-iso-propane- and hydroxy-n-butane-sulphinic acids.  The printing paste may contain coagulable thickening agents, such as cellulose ethers, polyvinyl alcohol, carob bean flour, carob bean flour ether, ethers of gum Guar or alginates, and alkaline agents, such as sodium or potassium hydroxides or carbonates, may be added to the printing paste or to the reducing agent solution which is padded or printed on the textile.  Alternatively, the printing paste may contain non-coagulable thickening agents, such as tragacanth mucilage, alkaline agents being then added to either the printing paste or the reducing agent solution, in which case the reducing agent solution may be sprayed on to the textile.  The heat treatment may be effected at 80-200 DEG  C. for 10 to 60 seconds by treatment with steam, or in molten metal, hot oil or hot aqueous salt baths, or by contact with a heated metal surface, air being excluded in all cases.  The process is applicable to textiles of native or regenerated cellulose, natural silk or polyamide fibres.  Numerous examples are given, in one of which the reducing agent padding solution also contains a vat dyestuff.

Title: Safety devices for hydraulically operated vehicle brakes
IPC: B60T17/22
Filed: 1954-09-23
Abstract: 749,421. Hydraulic brakes. BERG, K. W., BERGER, H., KNUTSEN, K. H., BALCHEN, F., TVEIT, J., AARDAHL, S., and OTTESEN, L. Sept. 23,1954 [Sept. 25, 1953], No. 27582/54. Class 103 (1). In a hydraulically operated brake mechanism for vehicles of the kind in which a device 1 is fitted between the master cylinder (not shown) and the separate supply pipes 11 for each of a number of brake cylinders to prevent leakage of hydraulic fluid should a leak develop in any supply pipe 11 or the brake cylinder connected therewith, said device 1 comprises a series of flexible diaphragms 2 arranged in pairs in the bore of the device 1 and separated by annular members 3 and clamping discs 4; each clamping disc being provided with a concave surface 6, the diaphragms defining the chambers 8 and the chambers 7. Each chambor 7 is in communication with an individual brake cylinder via passageways 9<SP>1</SP>, 9 and separate supply pipe 11. A tapered valve member 14 is provided in a radially projecting enlargement of the device 1 which, in the position illustrated, permits operating liquid under pressure from the master cylinder (not shown) to flow through passage 16, bores 15 and 18 in valve member 14, into longitudinal channels 19 and thence via grooves 10 of the respective annular members 3 into the respective chambers 8. The valve member 14 is also provided with two diametral parallel spaced bores 20, 21 extending at right angles to the bore 18 by means of which four channels 20<SP>1</SP>, 20<SP>11</SP> and 211, 21<SP>11</SP>, respectively leading to the grooves 9 of the respective clamping discs 4, can be connected to the liquid inlet 16. In operation, the chambers 7 and the supply pipes 11 are filled with hydraulic fluid and when the pressure within the chambers 8 is increased, this pressure increase is transmitted to the liquid within chambers 7 by movement away from one another by the diaphragms 2. Should a leak occur in any of the supply pipes 11 or in the brake cylinders proper, the diaphragm 2 forming part of the chamber 7 communicating with the appropriate supply pipe 11 will, with any increase in the pressure within the adjacent chamber 8, be forced into an inverted position in which it is seated on the surface of the adjacent cavity 6 to seal passageways 9<SP>1</SP>. When the leak has been rectified, the affected chamber 7 may be refilled with pressure fluid by turning the valve member 14 through 90 degrees from its normal position illustrated so that the chambers 7 are connected to the liquid inlet 16 while at the same time the channels 19 leading to the chambers 8 are closed. After such refilling the valve member 14 may be returned to its normal position. A fine wire mesh screen may be fitted to cover the openings 9<SP>1</SP> in each rigid clamping disc 4 to prevent damage to the diaphragms.

Title: Methods of conditioning and treating lime and product thereof
IPC: C04B2/04
Filed: 1946-09-17
Abstract: Hydrated lime having a high plasticity substantially immediately upon mixture with water is prepared by pounding between surfaces any of three types of finely-divided hydrated lime so as to form the particles into clusters.  The pounding is suitably carried out in tube, ball or rod mills.  The limes are as follows: (i) a lime which has been hydrated at a temperature above 212 DEG  F. and pressure above atmospheric in the presence of a large excess of liquid water until the hydration of the calcium oxide is complete, whereupon the major portion of the surplus water is removed by spontaneous vaporization, as disclosed in Specification 529,481; (ii) a magnesia-containing lime which has had the calcium oxide content completely hydrated in the presence of a large excess of liquid water, the surplus water not being substantially greater than that required for the hydration of the magnesia, and which has had the greater portion of the magnesia hydrated at a temperature above 212 DEG  F. and pressure above atmospheric; (iii) a magnesia-containing lime, which when hydrated by ordinary procedures in which little or none of the magnesia is hydrated has a high (defined) plasticity when soaked in water for a period of hours, and which has had, in addition to its calcium oxide content, at least the major portion of its magnesia content hydrated.  For the production of lime (i), apparatus as disclosed in Specification 529,481 is shown.  As in that Specification, hydration pressures rising to 600 lbs./sq. inch are employed, although pressures as low as 10 lbs./sq. inch are feasible. Instead of the quick release of pressure, a spray drying operation may be employed.  The lime to be tube, &c. milled may contain a little moisture.  Specifications 7079/10, [Class 1 (iii)], and 560,824 also are referred to.
