Abstract: 521,148. Artificial silk &c. COURTAULDS, Ltd., and WORMELL, R. L. Oct. 13, 1938, No. 29703. [Class 2 (ii)] Threads which have been formed by extrusion of a solution of casein or like protein substance, e.g. soya bean protein, into a coagulant and have been thereafter treated with a hardening agent are further treated with a salt solution adjusted if necessary as regards its acidity, which brings the pH of the threads to a value at or about the isoelectric point of the protein. The excess moisture is removed from the threads and the latter are then heated in the presence of moisture. The salts used have a buffering action in solution over a pH range in the region of the isoelectric point of the protein, e.g. in the casein about pH 4.6. Sodium phosphate, phthalate, lactate, borate, or acetate, or aluminium acetate or substances forming it, e.g. aluminium sulphate and sodium or calcium acetate maybe used. If acetic acid is liberated in the formation of the solution it may be neutralized with sodium carbonate. The hardening solution may be aluminium sulphate solution or formaldehyde solution. After the hardening treatment the threads may be subjected to the treatment with salt solution with or without intermediate drying. Heating in presence of moisture may be effected in a closed container at a temperature of at least 50‹C. In an example a solution of casein in caustic soda solution is extruded into a salt and acid bath and the fibres are hardened with a solution containing aluminium sulphate, sodium carbonate and acetate, and formaldehyde. The fibres are washed and dried and then immersed in a solution of aluminium acetate made by mixing aluminium sulphate solution with lime and acetic acid, filtering off the calcium sulphate, and adding soda ash to neutralize excess acetic acid. The fibres are removed, whizzed free from excess liquor and heated in a closed vessel. In another example, casein fibres are hardened with aluminium sulphate, stapled, and then treated with a solution of sodium acetate, formaldehyde, and acetic acid. In another example, casein fibres on a conveyer are hardened with a solution of aluminium and sodium sulphates and formaldehyde. The fibres are then stretched in a solution of sodium acetate and acetic acid, wound up on a reel in a bath containing sodium acetate, acetic acid, and formaldehyde. The wound fibres are left in a closed vessel for several hours and then heated. They are then placed in cold water.

Abstract: A process for chemically resolving a mixture of enantiomers of primary amines, such as enantiomers of 1,3-dimethyl-5-methoxyoxindolylethylamine, provides one of the enantiomers in the form of a tartaric acid salt. In carrying out the process, an enantiomeric mixture is contacted with a chiral acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The resulting precipitate can then be recovered. The chiral acid is selected from the group consisting of dibenzoyl-D-tartaric acid, dibenzoyl-L-tartaric acid, ditoluoyl-D-tartaric acid, and ditoluoyl-L-tartaric acid. The precipitates can be used in the synthesis of stereospecific forms of physostigmine.

Abstract: Low viscosity and high pH disinfecting and bleaching all purpose cleaning compositions in microemulsion form, suitable in both concentrated and diluted forms for applying to surfaces to be cleaned and disinfected or sanitized, include hypochlorite, higher alcohol sulfate and higher paraffin sulfonate detergents, higher fatty acid soap, alkali metal hydroxide, liquid hydrocarbon, perfume, periodate, branched lower alcohol co-surfactant and water. The compositions are of improved lipophilic soil removing capability when diluted with water, are of about equivalent such capability in neat or concentrated form and are of significantly better hypochlorite stability on aging at room and elevated temperatures, compared to other microemulsion cleaners that contain hypochlorite. Their low viscosities facilitate spraying them from squeeze bottles or pump sprayers onto surfaces to be cleaned and disinfected or sanitized, such as floors and walls. The absence of any builder salts allows uses of the compositions, especially in diluted form, to clean surfaces without the need for rinsing (wiping sufficing), and the cleaned surfaces are not objectionably streaky afterward. The concentrated microemulsions are effective removers of mildew from bathroom tub and shower tiles, and other surfaces, but in such cases rinsing is usually desirable. Also described are processes for the manufacture and use of the described cleaning compositions.

Granted: 2005-04-19
Abstract: In a battery housing and charging system for a range of cordless tools, a universal charger accepts battery packs of several configurations and size (number of cells). The common feature of the battery packs is (at least) one cell housed on end and substantially coaxial with a specific terminal block assembly. Terminal pins are shielded from external contact and engage the charger terminals in a recessed well in the floor of the charger receptacle.      Charger terminals are at one end of the receptacle which is elongated so that it can accommodate a battery pack "nose" portion with either one or two cells housed on end and side-by-side. Upright side walls of the receptacle provide stabilizing support for the battery pack In the battery pack portion outside the receptacle, cells may be arranged in any configuration to suit tool or other requirements. Charger output terminals are normally biased away from their respective terminal apertures to minimize risk of accidental contact with live terminals. Charging control circuitry, including means for sensing battery temperature, is all contained in the charger assembly, with a visible indication of charging condition registered by a light emitting diode and transmitted externally through an optic light pole. In assembly of the charger, accurate register of charger output terminals carried on a printed circuit board, with corresponding terminal apertures in the floor of the charger receptacle is achieved through the mutual engagement of a tapered dowel and mating hole in these parts.

Abstract: Apparatus for inspecting the sealing surface (36) of a container finish (34) that includes a light source (42) positioned to direct light energy onto the container sealing surface as the container is held in stationary position and rotated about its central axis.      A camera (48) that includes an array (80) of light sensitive elements (80a through 80n) is positioned and oriented with respect to the container axis of rotation (23) to receive light energy reflected by the sealing surface, with the camera having an effective field of view limited to an angular portion (58) less than the entire circumference of the container sealing surface. The camera array is scanned at increments of container rotation to develop information indicative of intensity of light at each array element as a function of such increments, and commercial variations in the container sealing surface are detected as a function of such information. The camera array is oriented with respect to the container axis of rotation and coupled to the scanning mechanism to scan the array in linear fields orthogonal to the axis of rotation, and scan information is stored for subsequent analysis in two-dimensional electronic memory (54) as a function of array element and scan increment. The light source is strobed at increments of container rotation and the camera array, which may be either a linear array or an area array, is scanned at each strobe increment of container rotation.

Granted: 1994-10-25
Abstract: The invention relates to a crawler track mechanism-mounted self-propelled, continuously operating open-cast mining machine with a drum-shaped mining device having cutting tools aranged around the periphery of the drum. The cutting drum (1) fitted with cutting teeth (4) can carry out cutting in both directions. The mined material is directed into the interior of the cutting drum (1). Cutter bars (2) are arranged in a substantially axial configuration around the circumference of the drum and the teeth holders (3) mounted on the cutter bars (2) carry teeth (4a, 4b). The teeth holders (3) with the teeth (4a, 4b) are tiltable about an axis (8) in such a manner that the teeth angled upwards in the direction of rotation automatically pivot into the cutting position as they engage in the material to be extracted, and the teeth (4b) pointing in the opposite direction are simultaneously swung out of the clearance angle zone (6) of the teeth (4a) doing the cutting. The material mined is transported by the cutter bars (2) and the flights (33) over a curved liner (9) and a feed chute (10) onto a discharge belt (11) axially arranged within the cutting drum. This belt transports the mined material to the end of the cuting drum and discharges it onto further conveyors (12, 13, 14) located outside the cutting drum (1). The mining machine is equipped with two sets of crawler track mechanism units (21, 22) which can be raised and lowered independently of each other by means of lift cylinders (24) and parallelogram links (23). Sensors (39, 40, 41, 42) are provided to divide up the loads via a programmable controller (43) between the individual crawler track mechanism units (21, 22) and to ensure that the attitude of the equipment chassis (19) is maintained during the various operating phases of the mining machine.
