Patent GB-1301788-A (GB)
IPC: D04H3/07
Filed: 1971-04-19
Abstract: 1301788 Non-woven fabric CHAVANOZ SA 19 April 1971 [19 March 1970] 24419/71 Heading D1R A non-woven fabric is made by simultaneously winding weft yarns 31-33 from packages 146, 148, 166 around a pair of spaced yarn supports 40 to form a sheet of weft yarns, at least one of the yarn packages being carried by a support 142 or 144 which is biased against rotation, and combining one or more sheets of warp yarns 90, 92 with the weft sheet to form the fabric. Three tubular yarn-guide arms 19, 20, 21 are secured to a hollow shaft 22 rotatably driven through a chain 29 from a motor 24. Each support 40 is helically threaded and removably secured to a stub shaft 46 journalled in a cross-bar 48 and rotatably driven from the shaft 22 through a sprocket wheel 54. Locating stops 56 positioned beneath each support 40 prevent rotation of the supports about the axis of shaft 22. The weft sheet as it reaches the ends of the supports 40 passes through nip rolls 84, 86, to combine with the warp sheets 90, 92 and is secured thereto by passing through an adhesive bath 100 and over drying rolls 104, 105. A creel rotor 17 comprising tubes 118, 120, 122, 124 is journalled in bearings 112, 114 to rotate with the shaft 22. Stub shafts 128, 130, 132, secured to the creel rotor are mounted in bearings 134, 136, 138, 140 attached to the package supports 142, 144 which are biased against roation by counterweights 156 and each comprise a shield 150 housing yarn packages 146, 148 connected top to tail and hinged to the shield. A further yarn package 166 is hinged to a support member 170 outside the creel rotor. In operation, weft yarns from the packages 146 and 166 are led through respective creel tubes, the shaft 22 and yarn guide arms 19-21 to be wound around the supports 40. Instead of the counterweights 156, rotation of the supports 142 and 144 may be prevented by magnets.

Abstract: Tea leaves are sprayed with liquor containing at least 80% alcohol before the fermentation stage of their manufacture. Preferably, 1 to 5 fluid ounces of spirits of wine containing 2 to 10 gms. fructose is used.  The leaves may be passed through a stream of droplets coming from an atomizer.  In the example given, 10 gms. fructose were dissolved in 5 fluid ounces of the spirits of wine (ethyl alcohol) and the solution was sprayed on 1000 lb. of unfermented tea leaves. The leaves were then rolled, fermented and finally processed.  The liquor may then contain colouring matter.  The Provisional Specification describes also the application of the process to tobacco and other similar leaves.

Abstract: 502,341. Preventing dimming of windscreens and windows. ROYCE, B., and ROYCE, G. B. Sept. 14, 1937, No. 25000/36. [Class 20 (iii)] Dimming of a vehicle windscreen or window by condensed moisture is prevented by delivering compressed air, preheated by the engine exhaust, from an engine-driven fan or blower to one or more nozzles formed and placed so as to eject flat streams of air across the surface of the screen or window. 'In the form shown, air is drawn into a muff 11 encircling the engine exhaust manifold and is delivered by a contrifugal fan 6, through a pipe 12, to one or more nozzles 15 mounted at the top of the windscreen 2. As shown in Fig. 3, these nozzlcs are formed with narrow, elongated apertures 16 in order that the air may be ejected therefrom in flat streams. An independent electric heater may be utilized to supplement the heat imparted to the air by the engine exhaust, or the outlet pipe 12 may be taken through the engine cylinder block, and instead of using a rotary fan, a piston pump, such as the pump employed for inflating the tyres, may be employed for delivering the air. The quantity of air ejected. from the nozzles may be controlled by a valve 17.

Title: Reel device for electrical flex
Inventor: ROSS FRANCIS CECIL
IPC: H02G11/02
Filed: 1954-08-31
Abstract: 808,724. Preventing slack. ROSS INDUSTRIES Ltd. Aug. 3, 1955 [Aug. 31, 1954], No. 25198/54. Class 78 (2). Figs. 1, 2.-A spring drum 6 carries electrical flex 15A having plugs 15, 19 affixed at its respective ends and is supported on wall bracket 8. The drum carries holding socket 14 which is coupled to locking pin 16 by pivoted lever 17, the pin 16 engaging in hole 8A formed in bracket 8. Pawl 10 carried by reel 6 engages with recess 11A formed in plate 11 fixed to shaft 7. An electrical equipment is wired up as follows. Plug 15 is placed in socket 14 so as to remove pin 16 from hole 8A in bracket 8 and thus to free the reel on its shaft 7. Then plug 19 is run out to the electrical equipment, the exact length of flex pulled out being adjusted till pawl 10 snaps back into recess 11A in plate 11. The reel is now positioned for the operator to remove plug 15 from socket 14, the removal allowing pin 16 to project into hole 8A to secure the reel. Plug 15 is then run out to the power point positioned near the reel, the reel being positioned to form two portions 6B, 6C as shown to allow a short length of flex to be run out with plug 15. Figs 4, 9.-Spring reel 30 is rotatably mounted on shaft 40, said shaft being rigidly secured to support arm 38. The latter arm is secured on a wall close to a source of power, e.g. electric socket. Disc 33 is mounted on shaft 40 in slot-and-pin relationship with the support arm so as to be capable of a small rotation around the shaft, said rotation serving to displace actuating member 49, the latter being secured to the disc. Contact holder 46 is carried resiliently by pivoted flange 45, being biased by spring 48. Pawl 35, carried by the reel, cooperates with notch 43A formed in disc 33. The small movement of said disc 33 causes contact holder 46 to engage the electrical contact plates 51 of the reel in the following manner. Operation. - Operator pulls out the electric flex (not shown) against the spring of reel 30, then releases it slightly to allow pawl 35 to find and engage notch 43A in disc 33. The latter therefore makes its small movement to displace actuating member 49 to release contact holder 46. The latter moves to the right to engage plates 51 to establish a current through the electric flex to the electrical apparatus. Conversely, if flex is tugged, pawl 35 is disengaged, and contact holder 46 is moved to the left to break the current flowing in flex.

IPC: H01B11/12
Filed: 1956-08-17
Abstract: 844,447. Preventing inductive disturbance. KABELWERK OBERSPREE VEB. Aug. 17, 1956, No. 25226/56. Drawings to Specification. Class 40 (4). The Specification states that for a star-quad to have a satisfactorily low value for intercircuit couplings at high frequency it is not only necessary that the couplings measured at low frequency shall be low, but that the individual components making up these couplings must also be low. Otherwise if the low resultant coupling is due to the difference between two large opposing couplings in different sections of the cable, then at high frequencies the phase shifts may be such as to render the coupling intolerable. According to the invention the manufacturing lengths are divided into sub-sections whose couplings over the whole frequency range are within the required tolerance limits, the cable then being reassembled with alternate lengths having couplings of opposite sign.

Abstract: 241,221. Koppers Co., (Assignees of Morgen, R. A., Yard, W. S., and Rosenstein, L.). Oct. 11, 1924, [Convention date]. Sulphur. - Solutions of alkali sulphides produced in gas-purifying processes are regenerated with liberation of free sulphur by oxidizing by means of air of oxygen in the presence of sulphide of nickel or cobalt, which acts as a catalyst. In the plant shown in the Figure a gas is scrubbed in a tower 2 with sodium carbonate or other alkali fed from a tank 16 to a spray 4. To the sulphided liquor .a small quantity of nickel sulphate is added whereby a fine suspension of nickel sulphide is produced. The sulphided liquor containing the catalyst passes to a tank 7 and overflows on to a sluice 10 whence it finally reaches a tank 12 which, when full, is emptied by means of a pump 13, the regenerated liquor being returned to the tank 16. The sulphur resulting from the oxidation of the liquor by the air collects on the sluice 10 and is removed. Sodium phosphate may also be used for scrubbing the gas. The Specification as open to inspection under Section 91 (3) (a) comprises also the oxidation of any liquor containing sulphides and the use of any catalyst. This subject-matter does not appear in the Specification as accepted.
