Abstract: 147,886. Textil-Industrie Akt.-Ges., (Assignees of Kneusels (nÚe Ellenbeck), M. (Representative of Kneusels, M.). June 15, 1917, [Convention date]. Void [Pubilshed under Sect. 91 of the Act]. Beat-up motions; lays; reeds.-The beat-up is effected by a number of slidable bars 4, Fig. 1, arranged parallel to the warp threads and operated by a lay 10 and a transversely-movable jack 11. The bars have noses 5 adapted to engage the weft and projections 6 adapted to be engaged alternately by projections 8, 9 on the lay. In operation, the lay moves the bars 4 to the left to engage the weft and is then moved to the right into the position shown in full lines. The jack 11 then moves transversely to the bars, and one of its inclined faces acts on projections 7 on the bars to move them into the position shown in dotted lines to beat-up the weft. Upon further movement of the lay to the right, any bars that have not been moved by the jack are engaged by the projection 8 on the lay. In a modification, the bars 4, Fig. 5, are controlled by " heddles " 26 of the jacquard apparatus through intermediate levers 14, 15, which are tiltable about pins 19, 18 and are slidable thereon and have engageable projections 29, 28. The levers 14 have projections 30 for engagement with projections 31, 31a on the lay 10<a>, and the levers 15 have noses 25 adapted to be retained by a bar 27. At the beat-up, the transversely movable jack 11<a> releases the noses 25 from the bar 27 and the levers 14, 15 move to the right under the action of springs 20, 21, serrated projections 24 on the levers 14 engaging serrations 23 on the undersides of the bars 4, which thus beat up the weft with the aid of weighted strings 22. Any bars that have not been moved are brought to the beat-up position by engagement of the projections 30, 31 when the lay moves to the right, the lay being lowered at this time to disengage the members 23, 24. When the take-up motion is not actuated during weaving, the parts 23, 24 come into engagement at increasing distances from the fell of the fabric. When sufficient fabric has been woven, the lay is lowered to disengage the parts 23, 24 and the bars are moved by the weighted strings 22 to follow the fell as the fabric is taken up. The levers 14 and the lay may be omitted, the projections 28 then engaging the parts 23 of the bars 4.

Title: Device for Measuring the Concentration of Narcotic Gases in Clinical Routine.
Inventor: MOYAT PETER EMO
IPC: A61M16/10
Filed: 1967-05-02
Abstract: 1,174,491. Anaesthetic apparatus. P. E. MOYAT and H. P. VONDERSCHMITT. 2 May, 1967 [5 May, 1966], No. 20187/67. Heading A5T. [Also in Divisions Gl and G3] A device for measuring the concentration of an anaesthetic gas in the gas flow to be applied to a patient in clinical routine comprises a casing having a passage 28 through which the gas flow passes, tapes 68, 70, 72 being supported under tension in the passage 28 and being of such material that the length of the tapes varies in a reversible manner with the concentration of anaesthetic gas contacting the tapes, the variation in length of the tapes being sensed by a string 78 passing round a spindle 80 carrying a pointer 20, the string 78 being fixed to the free end of a single blade spring 82 secured in a block 84, and the spring 82 carrying a plate 110 (Figure 3) which partially interrupts a light beam B incident on a photoresistor 118 connected in a bridge circuit having a recorder R which records the variations in the position of the free end of the spring 82 and thus the concentration of the anaesthetic gas. The voltage developed across a resistor in series with the recorder R may be used to control a servomotor actuating a valve in the supply line for the anaesthetic gas, so that the device may be used to maintain the concentration of this gas constant. The tapes are preferably of silicone rubber and may be used in the detection of 1-bromo-1-chloro-2, 2, 2-trifluoroethane, 1, 1, 1-trifluoro-2-chloro-2-bromoethane, 1-bromo-1-chloro-2, 2-difluoropropane, and 2, 2-dichloro-1, 1-difluoroethyl methyl ether. The tapes are mounted between two frames 42, 58, the frame 42 being supported by a flat spring 38 having a hooked end attached to one end of a string 48 of nylon the other end of which is secured to the wall of the passage 48. The string 48 increases in length with water vapour concentration so that this mounting of the frame 42 compensates for changes in water vapour concentration affecting the length of the tapes 68, 70, 72. The frame 58 is carried by a bimetallic spring 54 which compensates for the effect of temperature changes on the tapes. A frame 60 is mounted to tension the tapes at their midpoints, through the action of the string 78 and spring 82. The light beam 8 emanates from a casing 112 (Figure 3) containing a lamp and collimating lens, and is deflected by a mirror 116 passed the edge of the plate 110 on to the photoresistor 118.
