The dyes are prepared by reacting the corresponding dyes in which one of Z 1  and Z 2  is replaced by -NHR with a triazine of formula above in which the group -N(R) is replaced by hal; in the case where a cyanuric halide is used the resulting dye is further reacted with a compound of formula X<SP>1</SP>-H where X<SP>1</SP> has the same meaning as X apart from Cl or Br. The starting disazo compounds are prepared by diazotizing the appropriate amine and coupling to the corresponding copper complexed monoazo dyestuff, either of which contains a substituent convertible to an amino group; followed by formation of the amino group. The dyes are used for colouring various fibrous materials, particularly cotton, hemp, viscose rayon, polyvinyl alcohol, wool and polyamide, in purple or navy blue shades.

Feed-bars for reservoir pens ; overflow arrangements.-In a reservoir pen, the feed-bar B is formed with ink-channels D at the bottom of a longitudinal air-channel, side overflow chambers E communicating with the ink-channels D, and another overflow chamber L at the front end of the feed-bar B, the chamber L extending almost or quite up to the nib. In addition, other chambers S. Fig. 2, separated by a longitudinal web R may be formed at the back of the feed-bar in communication with the chamber L. The chambers S are covered by a plate T which is extended and bent up to touch the nut so as to form a cover for the channel L. An aperture J is formed in the plate T at a spot remote from the nib to admit air to the chambers S, L and to permit ink to rise in the chambers S. The chambers E communicate with the chamber L by passages M. with the chambers S by passages N, and with the ink-channels D by small apertures 0 which permit the passage of ink but prevent the passage of air, thus facilitating the return of ink to the reservoir when the pen is upturned. Nib-retracting reservoir pens.-The Specification as open to inspection under Sect. 91 (3) (a) also describes the provision of the overflow chambers in nib-retracting pens. An axial passage G. Fig. 3, (Cancelled), divided into two parts by a partition H, is formed in the feed-bar B, the cuter end of the partition being secured to the cover-plate of th chamber L which communicates by way of passages M with the chambers E as in the case of the fixed-nib pens. An air-aperture J is formed at the inner end of the chamber G, and the partition H is also apertured. The chambers E, G communicate with the ink-channels D through apertures 0, P respectively This subject-matter does not appear in the Specification as accepted.

In a magnetic recording apparatus, a spring-loaded resilient-tyred wheel 18 presses a magnetic tape 21 against a constant speed capstan 15, said wheel. being carried by a lever 17, pivoted at 16, which is adapted to be moved against a spring-loading 23 between operative and inoperative positions by an eccentric cam 24. In the embodiment described, the shaft 19 of the wheel 18 is suspended freely in apertures 20 in lever 17, and the spring 20x acting upon the shaft 19 serves to press the wheel 18 against the tape 21 and capstan 15 when the lever 17 is in the operative position.

[Class 40 (v)] [Also in Group XXXVI] Characteristics of a pulse a, Fig. 3, are translated into rectangular pulses of duration related to the desired characteristic, and this duration is measured. The pulse is applied at 12, Fig. 2, to a valve 20. Pulses b, c, and e, Fig. 3, appear at X, Y, Z, Fig. 2, the two last being produced by differentiating circuits C1, R1, and C2, R2. These pulses are applied to a limiting valve 41 to produce pulses b1, cl, and e1 Fig. 4, whose duration corresponds respectively to the base of the pulse a, its build-up time and its decay time. The pulses are inverted and applied to shock excite a heavily damped resonant circuit 69, L which is adjustable to give a maximum response ,in an indicator ; the tuning of circuit 69, L then .cprresponds to the duration of the pulses b1, cl and e1. The limiting valve 41 preferably consists of a double diode having the cathodes at an adjustable negative potential and the anode 43, to which the pulses a, c or d are applied at an adjustable positive or negative potential. The cathode potential mainly determines what width of the pulse applied at 43 shall appear in the anode circuit, while the potential of anode 43 allows the position of the " gate " to be shited over the pulse. Thus, by measuring the lengths of the pulse at different levels. its shape can be determined, Fig. 5, not shown. Specification 590,242 is referred to.

Title: Method and apparatus for filling bags
IPC: B65B1/18
Filed: 1959-05-11
Abstract: 918,104. Bag filling and weighing apparatus. BLACK PRODUCTS CO. May 11, 1959 [May 22, 1958], No. 16070/59. Class 143. [Also in Groups XVII and XXX] A weighinga pparatus for filling bags 25 with powder or granular material includes a hopper discharge unit 11 for charging a conditioning chamber 12, at atmospheric pressure, with a measured volume of material, whereafter the inflow to the chamber 12 ceases and a valve 29 opens to permit the material to pass from the chamber 12 to the bag 25, until the weight of the bag and its contents is sufficient to tip a scale mechanism 21 and cause the valve 29 to close. Cycle of operation.-With the chamber 12 filled to the desired level and the inflow thereto closed by a valve 42, a start button is pressed. This causes an air vent 55 to close and the valve 29 to open. The material in the chamber 12, fluidized by pressurized air from a diffusion pad 27, flows through a spout 24 into the bag. Since the conditioning chamber 12 is temporarily sealed, the air pressure therein will build up to create an artificial head which compensates for the decrease in actual head as the material level drops. An auxiliary air supply 75 can be used to bring the pressure up rapidly to increase the total head in the chamber 12. Upon the tipping of the scale mechanism 21, a flexible pipe leading to the spout 24 is flattened by a pinch valve 29 to stop the bag-filling operation. The recharging of the chamber 12 is then automatically initiated. The chamber 12 is recharged by stopping the air supply to the pad 27, opening the air vent pipe 55, opening the valve 42, and then supplying pressurized air to a diffusing pad 16 below the hopper discharge unit 11. The contents of the hopper 11 then flow via a pipe 13 into the chamber 12, until the level of the contents therein contacts a rotating paddle wheel 51 to indicate that the desired level of material has been reached. The apparatus is then ready for the next bag filling operation.
