Title: Improvements in or relating to cover panels for inspection and like openings
Inventor: LOVE JOHN
IPC: E05C3/12
Filed: 1951-10-12
Abstract: 713,092. Covers for inspection &c. openings. K.A.C., Ltd. Oct. 8, 1952 [Oct. 12, 1951 ; Oct. 31, 1951], Nos. 23813/51 and 25478/51. Class 107 A cover panel 'or an access opening in aircra't or other vehicles or apparatus has a handhole therein for easy removal. The hand hole is closed by a cover that is moved bodily inward to release the latch means retaining the main cover in position. Before the hand-hole cover can be dsp'aced bodily inwards it must be given a pre'iminary movement in another direction to release the catch holding it in place. In one embodiment the hand-hole cover 14 is pivoted about the axis 13 in the direction of the arrow A to cause the abutting face 27 of a catch projection 26 to disengage from the keeps 28 fastened to the main cover 5. When this is done the hand-hole cover can be moved bodily inward on the arm 12 and it displaces the lever arm 9. This latter has one end 7 forming a latch which engages behind the flange 4 of the access opening to prevent the main cover from being removed until the hand-ho'e cover is displaced. The lost motion due to pin 18 working in slot 17 allows the main cover to be replaced even when the hand-hole cover is in its closed position. Springs (not shown) urge the hand-hole cover closed and stronger springs force the main cover open when the latch 7 is re!eased. The access cover may be hinged to the main body of the aircraft. In another embodiment (not shown) the pins (13) in which the hand-hole cover (14) is pivoted have a flat formed on them and co-operate with bayonet slots. A pivotal movement o' this cover will release it for bodily inward motion.

Title: Improvements in and relating to cellulose derivatives and shaped structures made therefrom
IPC: C08B11/20
Filed: 1936-12-02
Abstract: Cellulose ethers which are soluble in caustic soda solution but insoluble or scarcely soluble in water, are improved as regards their solubility and their filtering and spinning capacities, by exposing the isolated and dried ethers to a temperature exceeding 40 DEG  C., e.g. to a temperature between 40 and 250 DEG  C.  The treatment of cellulose ethers which are soluble in caustic soda solution only on refrigerating the mixture, e.g. as described in Specification 212,864, [Class 2 (ii)], is included.  Suitable cellulose ethers are those containing not more than one ether group per one or even ten or more cellulose units, e.g. such alkyl ethers prepared as described in Specifications 177,810, 200,816, 200,834, 203,346, 203,347, [all in Class 2 (ii)], and 374,964, hydroxy-alkyl ethers as described in Specifications 231,807 and 231,808, [both in Class 2 (ii)], and hydroxyparaffin monocarboxylic derivatives as described in Specifications 231,809, 231,810, and 231,811, [all in Class 2 (ii)]. The action of the heating on the cellulose ether may be accelerated or intensified by the addition of a thorium salt, a cerium salt, an alcohol, or an inorganic or organic nitrogen base.  The products may be further improved by treating them with an acid or acid salt, e.g. hydrochloric or sulphuric acid of 0,5 to 3 per cent strength at room temperature.  The cellulose ethers may be worked up into products such as filaments, films, plates, adhesives, finishes, coatings and the like, by contacting the shaped solution of the cellulose ether with an agent having a coagulating and/or a plasticizing action on the shaped material, e.g. a bath containing from 25 to 70 per cent of sulphuric acid.  The cellulose ethers may be worked up into xanthates, examples of such processes being described in Specifications 335,993, 335,994, [both in Class 2 (ii)], 357,167, 357,527, 357,595, 459,122, 459,123, 459,124, 462,283, 462,456, 462,712, and 462,713.  According to the Provisional Specification the invention may also be applied to the treatment of cellulose esters which are at least partially soluble in caustic soda solution, these including cellulose mono-esters of dicarboxylic acids, and alkali-soluble cellulose nitrate.  Specifications 281,352, 312,197, 323,731, 323,732, [all in Class 2 (ii)], 341,899, 356,776, 408,950, 457,031, 470,746, 472,888, 472,933, and 474,223 also are referred to.

Filed: 1973-05-21
Abstract: 1480478 NMR spinner assemblies PERKIN-ELMER Ltd 20 Aug 1974 [21 May 1973] 24065/73 Heading G1N An object, for example an NMR sample, is rotated in a magnetic field of intensity greater than 5 kilogauss and a homogeneity exceeding 1 part per million, and is provided with an eddy current brake which interacts with the stray magnetic field to oppose the rotation of the body. In Fig. 1 a glass sample tube 2 carries a sample within the working magnetic field of an NMR spectrometer magnet 1. The tube is supported by bearing 3, and also laterally by an air bearing (not shown). It is rotated by gas from a nozzle 6 interacting with a turbine rotor 58. An aluminium washer or annulus 5D is so dimensioned that it interacts with the stray field 1D to produce a braking force which helps to stabilize the speed of rotation produced by the gas from nozzle 6. In place of washer 5D a conductive slug 7, Fig. 2, may be positioned in the tube 2 to create a suitable eddy current brake. Although not explicable in ordinary electromagnetic theory, a braking effect is also stated to be observed when the assembly of Fig. 1 is used with the field along the axis of rotation, as in Fig. 3. In that Figure a turbine 12 is shaped to provide both rotation and lift to the glass tube, and the eddy current brake is at 13. If desired the turbine can be of aluminium and can serve as the brake as well.  It is stated that the use of these brakes does not disturb the results obtained by the NMR measurements. The turbine can be bladed or have a smooth surface; rotation rates are generally from 10-30 Hz.
