Abstract: 942,172. Portable grilling stoves. D. E. T. DAVIS. Oct. 27, 1961 [Nov. 7, 1960], No. 38482/61. Heading F4W. [Also in Division A4] A transportable sheet metal bucket-shaped grilling stove having feet, has ventilation holes in the bottom the dimensions and positioning of which are so chosen as to allow a few sheets of crumpled paper placed within the stove to serve as an initial fuel for grilling fatty viands and thereafter to allow the paper to form a charred base on which fat dropping from the viands can burn effectively to continue the grilling operations. The stove, Fig. 1, is constructed in three sections 7, 12 and 13, the middle section 12 having a number of small holes 18 and the bottom section 7 having holes 11 in its base, Fig. 6. The viands are sandwiched between two circular pieces of wire mesh hinged together which are supported on the stove by lugs 15 and handles 16. The handles 16 are slidably mounted and are pushed inwards, Fig. 5 (not shown), for stowing. The sections 7, 12 and 13 nest together for transporting, as shown in Fig. 3.

The tank is assembled in the inverted position, the side walls 40, 42 being first welded to the top wall 30 along lines 44, 46. Internal baffles and end bulk-heads 48, 50 are then spot-welded to side walls 40, 42 and to the top section 30; finally the bottom wall is welded in place along lines 54 and closing gussets 56 added.

Title: Method of detecting abnormal behaviour of mammalian cells
IPC: A61D13/00

Abstract: 1481605 Detecting abnormal mammalian cells; measuring fluorescence polarization YEDA RESEARCH & DEVELOPMENT CO Ltd 11 Sept 1974 [14 Sept 1973] 39598/74 Headings G1A and G1B [ Also in Division C4] The fluidity of the lipid layer of mammalian cell surface membranes is measured and compared with that of normal cells to detect abnormal behaviour therein. The cells are preferably intact. Measurement may be made by introducing a fluorescent compound into the lipid layer, exposing the cells to polarized excitation radiation and measuring the fluorescence polarization of the emitted radiation. The fluorescence intensities may be measured in two, mutually perpendicular planes, one of which is parallel to the plane of polarization of the exciting radiation and comparing the ratio of intensities in these planes with the ratio for normal cells. The ratio may be measured directly by using two detection channels, one for each polarization direction, or by using two alternating excitation channels having their directions of polarization perpendicular to each other; a single excitation channel may also be used, if it is switched from one polarization to the other. A particularly suitable fluorescent compound is 1,6 diphenyl-1,3, 5, hexatriene, or a lower alkyl derivative thereof.

Abstract: 1353808 Grinding GERBER GARMENT TECHNOLOGY Inc 24 Aug 1971 [26 Feb 1971] 39619/71 Heading B3D [Also in Divisions B4-B5] An apparatus for cutting sheet material 1 comprises a rotary abrasive cutting disc 16 driven by a motor 82, means 20, 22, 26, 28 for moving the tool relative to a penetrable bed 62 providing a supporting surface 64 for the material to be cut; and means 96, 130 for positioning the cutting tool along a line 94 generally normal to the work surface with a segment of the peripheral cutting edge of the disc extending below the work surface into the penetrable bed. The cutting disc 16 is rotated by an electric motor 82 mounted on a bracket 100 which is secured to a sleeve 96 slidable on a shaft 92. The shaft is supported by a bracket 88 secured to a carriage 22 which is movable by a feed screw 34 along a main carriage 20, the drive of both carriages being controlled by a computer 36.

Title: Improvements in or relating to circuit arrangements including charge storage tubes
Inventor: SCHAGEN PIETER
IPC: G01S13/524
Filed: 1957-12-20
Abstract: 867,351. Radar. MULLARD Ltd. Oct. 2, 1958 [Dec. 20, 1957], No. 39662/57. -Class 40(7) [Also in Group XL(a)] In the operation of a storage tube, which includes a target having a storage surface provided with an electrically-conductive backing constituting a signal plate and means for scanning the electron beam over the storage surface, input signals are applied to the cathode to cause negative excursions of the cathode potential while ensuring that the potential difference between the storage element being scanned and the cathode is less than the first cross-over potential of the storage surface thereby permitting negative charge to be deposited on the storage surface in accordance with the input signals. Output signals corresponding to the deposition of negative charge are derived simultaneously from the signal plate. If the input signals are provided by a radar receiver circuit producing signals corresponding to echoes from both stationary and moving objects, output signals from the stationary object are only obtained during the first scan. However, in time a large part of the storage surface would become insensitive due to the negative charge deposited thereon due to signals from moving objects unless the storage surface is restored by raising the potential of the storage elements to the unmodulated cathode potential. With a storage surface of an insulating material, this may be done periodically by switching the cathode potential sufficiently negative during one scan that the secondary emission coefficient is greater than unity for all elements of the storage surface, or continuously by applying to the cathode a sawtooth waveform such as that shown in Fig. 7a. Alternatively the storage surface may be of a resistive material, or a photoconductive material, exposed to radiation through a transparent signal plate, a potential equal to or positive with respect to the unmodulated cathode potential being applied to the signal plate in each case. In a further embodiment the storage surface is of a photo-emissive material, exposure to radiation causing a steady leakage of electrons to a collector mesh disposed in front of the target.

Abstract: 1,156,816. Papermaking. FLEMING & SONS Inc. 6 Sept., 1966 [13 Sept., 1965, 7 Feb., 1966], No. 39788/66. Headings D2A and D2B. Porous paper for gypsum wallboard has a bonding surface and an exposed surface, and is made by forming a slurry of papermaking fibre, adding to the slurry a sizing agent that remains water-resistant up to at least 140‹F, treating the slurry to retain the sizing agent at least until the slurry is nearly dried into paper, feeding the slurry to a Fourdrinier process, drying the paper, finishing the bonding surface at the calender stacks with water, and finishing the exposed surface at the calender stacks with an aqueous wax emulsion or a combination of starch and aqueous wax emulsion. As shown, the slurry 11 from the headbox 10 passes to the Fourdrinier screen 12, processing rolls 13 and wet stack 14, where the bonding surface is finished with water from a trough 15 and the exposed surface with wax emulsion or wax and starch mixture from a trough 16. The paper is then taeated on the dry stack 17 and is rolled up at 18. It may have surface ornamentation applied by coatang or printing at 19 or 20 or at a later stage. In one process, the pH of the slurry is adjusted to 7-9, the sizing agent is an alkyl ketene dimer derived from palmitic, stearic, myristic or oleic acid, and is retained by the addition, as retention agent, of a watersoluble cationic thermosetting resin made by reacting a polyalkylene polyamine with diglycolic acid or a C 3  to C 8  saturated aliphatic dicarboxylic acid, and this product with epichlorohydrin. In another process, the pH of the slurry is adjusted to 3.5 to 5, the sizing agent is rosin-alum, and the bonding surface is finished with water made alkaline (pH of' 11 or more) with soda ash to remove sizing agent from that surface. This finishing water may contain a rewetting agent, e.g. a block copolymer containing oxypropylene and oxyethylene groups. Cream face paper may be made by adding a thin layer of light-coloured slurry from a second headbox.

Where the neutral is not available, an artificial neutral may be supplied, In a modification, the supply and load are interchanged, switch 7 is omitted and the contactor is closed manually,re maining closed if the phase sequence is correct but releasing if incorrect, due to energization of the trip coil 8a which causes the contactor to open.
