Abstract: 339,858. Johnson, J. Y., (I. G. F'arbenindustrie Akt.-Ges.). Aug. 24, 1929. Yarns &c., treating with liquids, gases, and vapours. - Fibres are softened and rendered flexible by treating with aqueous solutions of true sulphonic acids prepared from carboxylic acids of aliphatic saturated hydrocarbons containing more than eight carbon atoms, or with water soluble salts thereof. Suitable sulphonic acids are obtained, for example, as described in Specification 288,612, or from similar saturated acids as occur in fats or oils of vegetable or animal origin, and in oxidation products of paraffin wax. The quantities of the acids or their salts usually employed lie between 0.1 per cent and 5 per cent. The treatment may be carried out at temperatures which, preferably, do not exceed the boiling points of the solutions. In an example, cuprammonium silk is treated for 20 minutes with a solution of the monosodium salt of palmitic sulphonic acid or of stearic sulphonic acid at 50-60‹ C. In a further example the salt of triethanol amine with the sulphonic acid of stearic acid is used.

Patent GB-174396-A (GB)
Title: Improvements in speed governing transmission gear for water turbines and the like
IPC: G05D13/00
Filed: 1920-09-15
Abstract: 174,396. Magne, O. Sept. 15, 1920. Fluid relays. - Fluid-pressure transmission mechanism for the speed governing of turbines by controlling the guide-vanes comprises a servomotor having a floating piston slide valve, the pressures on the opposite end faces of which are so controlled as to bring this piston valve back to its normal position after having moved the servo-motor piston. Pressure fluid is supplied through pipes 26, 28 to the opposite sides of a servo-motor piston 12 and to the cylinder of a floating piston 15. A second piston 17 moves in an extension of this cylinder formed at rightangles and is provided with a port 23 controlled by a rod 24 moved by a speed governor 25. Normally sufficient pressure fluid continually escapes through the port 23 past the end of the rod 24 to maintain equilibrium on opposite faces of the piston 17, which remains stationary, but if the load on the turbine is reduced the speed increases, the rod 24 moves to the left restricting the escape of the fluid through the port 23 so that the pressure in the space 32 increases and the piston 17 moves to the left. This forces up the floating piston 15, which by one of its rings 21 uncovers a port in the cylinder 14 to allow pressure fluid to flow through pipe 28 to the back of the servomotor piston 12 which moves and adjusts the turbine guide-blades. As soon as the floating piston 15 has lifted sufficiently it uncovers an exhaust port 30, permitting escape of exhaust fluid from the space between pistons 15, 17, and the piston 15 sinks again to normal position. A valve 36 which slides to the left or right simultaneously with the piston 17 also admits pressure fluid through the pipes 33 to the space between the pistons 15, 17 to help to restore them to normal position. Control in the opposite direction, that is, when the speed drops below normal, is similarly effected by the piston 17 moving to the right and the piston 15 falling, an exhaust port 29 and another exhaust port 35 in connection with the valve 36 then being brought into position.

Abstract: 1345798 Bag filling machines MAYER KG 19 April 1971 [13 April 1970 26 March 1971] 26860/71 Heading B8C During filling, plastics bags are distended by pairs of arms 19, Fig. 1, each pair being separated to grip a bag, and subsequently brought together to release the filled bag, by the cooperation of a fixed rail 8 and a roller 11 which moves with the arms. The roller 11 is secured to a vertically slidable T-piece 9 which is connected to the arms 19 by pivoted links and which is biased by springs 12, Fig. 2, towards the position in which the arms are separated. The arms 19 carry fingers 20 to engage the bags and also carry strips 21 which extend above the bags so that the latter may be overfilled to allow for subsequent compression. The arms 19 and their operating links are mounted on a polygonal drum 5 which rotates with a turntable 2. Empty bags are placed on the arms 19 by an operator and the filled bags are either removed by the operator or fall on to a discharge conveyer 1. The distended bags are filled from a source 3 and, when they are to be used as flower pots, a drill may be formed by a device 4. In a modification, Fig. 8 (not shown), the arms 19, instead of carrying the fingers 20 and strips 21, each carry a curved plate (120) whose shape conforms to that of the filled bag. In another embodiment, Fig. 10, the bag filling apparatus forms a separate unit which overlaps, rather than rotates with, the turntable 2 of a potting or repotting machine. The turntable 2 carries containers 28 into which the bags fall after being pushed off the filling machine by a ram 26. The ram 26 acts through the same holes 23 that are used to fill the bags. As the apparatus rotates, each hole 23 passes beneath a fixed baffle 25 where it receives a pile of material that has accumulated from the source 3. The bags may be filled with potting compost, peat, fertilizer, plant seeds, grain, flour, cement, or dyestuffs. (For Figures see next page.)

Abstract: 423,725. Light current relays. BRONEE, T., 1, Kopischstrasse, Berlin. Sept. 19, 1934, No. 26961. Convention date, Sept. 26, 1933. [Class 38 (v)] [See also Group XXXVIII] Relays adapted to be operated by weak current impulses of short duration, particularly for the actuation of signals, counting mechanisms and the like by moving vehicles, have contacts which are caused to adhere together artificially by burning in such a manner that they remain in contact beyond the duration of the current impulse, the contacts being afterwards separated by the impacts of a hammer or vibrating mechanism. As shown in the Figure, the current impulses, which may be caused to emanate from a coil 1 on the passage of moving vehicles, are received by a relay A the coil 3 of which momentarily brings contacts 4 together on the first impulse. Immediately the contacts 4 engage a condenser 5, which has been charged by a battery 6, discharges across them and so fuses them temporarily together. The closing of the contacts 4 sets into operation a train of relays B .. D, of which the relay D completes at contacts 19 a controlled circuit fed from a transformer 21 across which signal lights 22, counting mechanisms 23 or further relays 24 may be connected. The controlled circuit also energizes an electromagnet 25 operating a vibrating hammer 26 which by striking either the casing of the relay A or the contacts 4 themselves, forces them apart in readiness for a subsequent operation. A thermal switch F is included in the circuit of coil 24 to interrupt its circuit and so reinforce periodically the blows of the hammer 26. If the contacts do not separate the whole system is ultimately cut off on operation of a slow-acting thermal relay E and switching-off relay G. The relay C is given a slow action by a series inductance 14 which with the relay coil 13 is bridged by resistance 15.
