Abstract: 1,223,199. Weaving terry fabric. CANNON MILLS CO. 13 Nov., 1968, No. 59309/68. Heading DIE. In a loom in which a loop of weft is taken halfway through the shed by one needle and transferred to a second needle which straightens out the loop into a single pick, the trailing end of the weft is prevented from becoming entangled with the relatively slack pile warp by lowering the upper sheet of the taut ground warp to about mid-shed line, and then returning it to the top shed line before the next pick. The movement is produced by an extra lobe on the appropriate tappet.

Abstract: 1,239,997. Cooling or heating buildings; cold and heat storing apparatus. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 6 Dec., 1968 [11 Dec., 1967; 11 June, 1968; 12 June, 1968], No. 58200/68. Headings F4H and F4U. Apparatus for heating and cooling a building comprises a thermally insulated vessel 137 containing a heat-storage liquid and a heat exchanger 129 of a heat-pump system, a heater (not shown) in the liquid and a conduit system for circulating the heat-storage liquid to and from one or more fan-coil units in rooms to be heated or cooled. The heat pump system comprises a compressor 103, a further fan-cooled heat exchanger (Fig. 3, not shown), expansion valves and a reversing valve 111; heat exchanger 129 comprises a plurality of finned tubes 141 fed with refrigerant in parallel by a distributer 145. The conduit system includes a pipe 149 having perforations 151 in its upper part for withdrawing liquid from the vessel, a flexible pipe 155 joining pipe 149 to a coupling 157, a pipe 150 for returning liquid to the bottom of the vessel, a flexible pipe 160 joining pipe 150 to coupling 157, and flow and return pipes connected between the coupling 157 and the fan coil unit(s) (Fig. 1, not shown). The flow pipe contains a pump. For cooling the room(s) reversing valve 111 is set so that heat exchanger 129 acts as an evaporator to freeze some of the heat storage liquid, a thermostat 152 attached to pipe 149 serving to stop the compressor before the liquid in the immediate vicinity of the pipe freezes. For heating, valve 111 is reversed so that exchanger 129 functions as a condenser until the heat storage liquid reaches a predetermined temperature; thereafter, the heat pump circuit is de-energized and the liquid is heated to a higher temperature by an electric heater. An electric control circuit (Fig. 8, not shown) including thermostats is provided. In a modification (Fig. 13, not shown) the refrigeration system is not reversible, and the heat exchanger within the vessel consists of spaced high and low temperature evaporators. The low temperature evaporator consists of finned tubes while the high temperature evaporator comprises an inner tube for the refrigerant and an outer tube through which liquid returning from the fan-coil unit flows before being discharged into the vessel. When the room requires cooling refrigerant is supplied to the high temperature evaporator, and when the room temperature is sufficiently low the liquid circulation is stopped and refrigerant is supplied to the low temperature evaporator to freeze the liquid. A thermostat responsive to the temperature of the liquid leaving the fan-coil unit may be provided for causing refrigerant to be supplied to the low temperature evaporator while the liquid is circulating and if insufficient cooling is available from the other evaporator. The heat-storage liquid is preferably water but may be diphenylene oxide or ethylene diamine.

Abstract: 1346329 Wet treatment of continuous fibrous materials MESSERSCHMITT - BOLKOW BLOHM GmbH 17 Dec 1971 [23 Dec 1970] 58673/71 Heading D1 In a process for the continuous wet treatment of fibrous materials the material 7 is passed into a chamber 5 defined by two pairs of calender rollers 1, 1 and 2,2 rotating in a tank 4 containing the treatment medium 3 through a gap 6 formed in the first rollers 1, 1 and in the chamber 5 is brought into contact with the treatment medium flowing in the direction of arrows 13 (see Fig. 2) as two contra-rotating vortices having core axes 14 and forming a boundary zone through which the fibrous material passes. In this boundary zone the treatment liquid passes through the material countercurrently and cross-currently and fans out the material. As illustrated the two vortices are induced in the treatment medium by the contra-rotating rollers of each of the two calenders, the treatment medium being dragged into the chamber 5 by the rotation of the roller 1, 1. The rollers of the second calender 2,2 may be formed with a circumferential groove 8 to allow the treated material to pass therethrough without contacting the rollers. Downstream of the rolllers 2, 2 there may be formed a vacuum chamber for degassing the treated material, the exit to this degassing chamber being formed by a drawing nozzle (Fig. 3, not shown), Figs. 4 to 7 (not shown) illustrate alternative methods of generating vortices of treatment liquid through which the fibrous material is passed. The process is particularly suitable for the impregnation or rinsing of carbon fibre materials.

Abstract: 1332170 Preparing chlorine DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 16 Dec 1970 [20 Dec 1969] 59683/70 Heading C1A A process for the production of chlorine from hydrogen chloride or gases containing hydrogen chloride comprises converting the gaseous hydrogen chloride into an aqueous solution containing 20-40% by weight of HCl and reacting with hydrogen peroxide. It is preferred that the hydrogen chloride is dissolved in a hydrogen chloride solution containing 20 to 40% by weight of the gas, the concentration of the solution after addition of the gaseous hydrogen chloride also being within the range of 20 to 40% by weight. Preferably the hydrochloric acid used as absorbent for the gaseous hydrogen chloride is at most 20‹ C. above ambient temperature. The chlorine gas obtained may be washed counter-current by means of hydrochloric acid of strength 25-35% which has been cooled preferably to 0‹ C. In a preferred embodiment hydrogen chloride is initially separated from the gases containing hydrogen chloride by optionally multiple stage countercurrent washing with hydrochloric acid of the specified concentration and then optionally with water, after which the heat of absorption is removed before the reaction of the hydrogen peroxide, and the cooled solution subsequently passed in parallel current with hydrogen peroxide through the filling of a reaction tower while the cooling gas formed is removed countercurrent and a portion of the dilute hydrochloric acid flowing back to the absorption stage is separated off in order to drain off excess water. A further embodiment is described in Fig. 2. Hydrogen chloride in a gas mixture is separated by adsorption in columns 1 and 2 and the 35% hydrochloric acid thus obtained is delivered to a desorption column 3 and hydrogen chloride boiled off. The hydrochloric acid azeotrope may then be recycled from the base of column 3 to the absorption column 1 while some is separated off and drained to remove excess water The gaseous hydrogen chloride is delivered to column 4 acting as a reactor, entering the column at 30‹ C. Aqueous hydrogen peroxide solution is delivered to the head of the column and the chlorine is withdrawn from the head of the column. The hydrochloric acid increased by the water of reaction and the water used to dilute the hydrogen peroxide is run off from the foot of the column and pumped to a heat exchanger 6 where it is cooled to 30‹ C. before re-entering the head of the column. Chlorine from the head of the column is freed from residual hydrogen chloride and steam in washer 5 with hydrochloric acid cooled to 0‹ C. in a heat exchanger 7. The effluent from the washer 5 is recycled and combined with the effluent from reactor 4. The system is operated at a pressure of around 0À4 atmospheres generated by a compressor 8.
