Filed: 1976-05-05
Abstract: 1523302 Closing vehicle body sides YORK TRAILER CO Ltd 5 May 1976 [5 May 1975] 18783/75 Heading E1J A curtain closing a wall of a vehicle body is made of woven material with the warp and weft threads so arranged that vertical tensioning of the curtain stretches the same and results in a tendency to contract in a horizontal direction, the vertical edges of the curtain being held against movement so that horizontal tensioning is simultaneously achieved. For example, a P.V.C. coated woven polyester fibre is employed for a curtain cut on the bias so that both warp and weft threads lie at 45‹ to the direction of tension forces applied by straps or cords secured to the curtain.

Title: Improvements in or relating to processes for converting alkali sulphides into alkali sulphites
IPC: C01D5/14
Filed: 1926-07-29
Abstract: 260,552. West Virginia Pulp & Paper Co., (Assignees of Drewsen, V.). Oct. 29, 1925, [Convention date]. Alkali sulphites; sodium sulphide, sulphite, and bisulphite. - Alkali sulphides are converted into sulphites by agitating and aerating the hydrous sulphides in the presence of solid comminuted surface-giving materials such as charcoal, coke, pumice powder, soda ash, anhydrous sodium sulphite, clay, or calcium or magnesium carbonate, preferably at a temperature of 120- 160‹ C. The process is particularly applicable to the recovery of sodium sulphite from spent sulphite liquors. Spent monosulphite liquors, or neutralized spent bisulphite liquors are concentrated and burned in a reducing flame, with or without an intermediate drying operation. The residue, mainly fused sodium sulphide, is run into a tank of water and agitated therein to form a hot solution which may correspond to the formula Na2S.9H2O. This solution is run continuously into a closed mixing machine maintained at a temperature of 140‹ C., and is there mixed with anhydrous sodium sulphite and subjected to the action of an air current, the resulting sodium sulphite being overflowed from the mixing-machine continuously. The process may, however, be carried out in stages in a series of mixing-machines. The crude sulphite so obtained may be dissolved in water and filtered and the solution then be concentrated to deposit anhydrous sodium sulphite; or the solution may be treated with sulphur dioxide to give the bisulphite. The conversion of the sulphide to sulphite is based on the following reactions :- (i) 2Na2S+4O+H2O=Na2S2O3+2NaOH. (ii) Na2S2O3+2NaOH+O2=2Na2SO3+H2O. The first reaction occurs if the temperature be kept at or below 120‹ C.; the second follows on raising the temperature to 140‹ C. with sufficient aeration. In the absence of sufficient oxygen, however, the second reaction is replaced by the following :- (iii) 3Na2S2O3+6NaOH=4Na2SO3+2Na2S+3H2O. Should this reaction occur, the sodium sulphite may be extracted with water for re-use. It is advantageous, but not essential, that the air used for aeration should be free of carbon dioxide.

Title: Electro-optical apparatus for rotating the plane of polarisation of a plane polarised light wave
IPC: G02F1/01
Filed: 1971-07-07
Abstract: 1353543 Automatic control of polarization BBC BROWN BOVERI & CO Ltd 7 June 1971 [9 June 1970] 19163/71 Heading G3R [Also in Division G1] #/4 plates 1, 3 are disposed either side of a Pockels or Kerr electro-optic cell 2 and with their axis at 45 degrees to those of the cell so that light incident on one #/4 plate leaves the other plate with a plane of polarization rotated by an amount controlled by the potential applied to the electrooptic cell. As described, the arrangement is used to nullify variations in the plane of polarization of an incident beam derived from a Faraday effect element 14 controlled by the current in a high voltage conductor 15. An A. C. voltage is passed to a differential amplifier 23 controlling cell 2 and to a phase detector 21. After passing an analyzer 16, the light beam falls on a photo-detector 20 supplying the other input to detector 21. The output of detector 21 is amplified 22, measured 24 and passed to the other input of amplifier 23. When the plane of polarization of the output light beam has a predetermined orientation with respect to analyzer 16, the output of detector 20 will comprise only the second harmonic of the A.C. frequency supplied to cell 2. Detector 21, preferably tuned to the A.C. fundamental, is therefore able to supply a signal indicative of the 'magnitude and sign of the deviation of the output plane of polarization from the predetermined plane, and the measurement 24 is thus a function (linear or square law, depending on whether a Pockels or Kerr cell is used) of the current in conductor 15. Reference has been directed by the Comptroller to Specification 1248752.

The relay may operate as a circuit breaker and may be tripped automatically by a fault sensing device which applies a positive potential to gate 43 of SCR 35. The SCR 35 turns on, as does transistor 21 to energize trip coil 13 so that movable contacts 5 and 11 of the relay change over to engage fixed contacts 1 and 9. Additional contacts in the associated circuit are also opened to protect the circuit. Manual trip may be provided by grounding control terminal 49 so as to make transistor 21 conduct to energize the trip coil 13. The relay is reset by applying a positive reset signal to the control terminal 49. This causes transistor 55 to conduct and energize the reset coil 17 so as to change the movable contacts 5 and 11 back to contacts 3 and 7. However the relay is prevented from being reset while there is an automatic fault signal on the gate 43 of the SCR 35 since the reset control signal at 49 is shunted to ground by the SCR. The SCR 35 will continue to conduct after the fault signal at 43 has been removed until the reset signal at 49 is also removed.
