Abstract: An improved method for laundering fabrics to remove oily soil is disclosed, wherein fabrics are contacted with a washing liquor comprising an aqueous solution of a nonionic surfactant system and other ingredients. The washing temperature and ingredients of the washing liquor are selected so that washing occurs at a temperature which is substantially above the cloud point of the washing liquor and below the phase coalescence temperature of the washing liquor. Compositions useful in the practice of this invention are also disclosed, comprising a nonionic surfactant to which is added one or more strong electrolytes. Such compositions may be diluted with water to form a washing liquor which has cloud point and phase coalescence temperatures which are tailored for washing, within the scope of the present method, at a temperature preferred in the art. Conventional sequestering detergency builders and adjuvants may be added to the compositions as desired to optimize the cleaning result. The compositions may be formulated to provide a washing liquor pH of less than about 11 without diminishing the cleaning performance of the washing liquor.

Abstract: A system for automatically controlling the voltage of an electrostatic filter with respect to its breakdown voltage limit. The detection of secondary voltage breakdowns which occur within a post-breakdown time period after an initial voltage breakdown cause the filter voltage to be lowered to zero value. After a deionizing time period, the filter voltage is gradually raised during a predetermined rise time period until it reaches a new value. The duration of the deionizing time period and the rise time period may be advantageously computed in response to the history of voltage breakdowns, by a microcomputer system.

Abstract: The invention relates to single facers for corrugated board of the kind comprising upper and lower corrugating rolls and a pressure roll, each of the rolls being formed by a hollow shell. 
     The invention provides an improved design of high practical value in which noise in use is substantially reduced. 
     The invention is characterised in that vibration reducing means (12,12a, b or c, 17, 18 to 20, 21, 22, 22 to 24 or 25, 26) are provided and located in the hollow interior of at least one of the rolls (4, 5, 7 or 16), said means being maintained in intimate contact with the inner wall of the shell of said one roll, the arrangement being such that the frictional resistance between the inner wall of the roll and the vibration reducing means restricts elastic deformation of the roll, and hence restricts the level of noise caused by elastic oscillation of the roll. 
     The vibration reducing means may comprise a coil (12), or other appropriate spring, or a coiled thin sheet (12a, b or c) maintained under pressure in contact with said inner wall of the shell. 
     Alternatively, said vibration reducing means may comprise a number of cylindrical elements (17, 18 to 20, 21, 22, 22 to 24, or 25 26) maintained in contact with each other and pressing into contact with said inner wall of the shell.

Abstract: An attachment device in the form of a bearing housing (10) and an arm (38) projecting out through an opening (44) in the housing. The arm is supported in a bearing support (42) in the housing and serves to carry, at the end opposite the housing, an ear muff to move with a rocking motion between a stationary rest position and a position wherein the earmuff exerts a pressure -around the wearer's ear. A separate spring component (44), preferably annular in form, is rotatably supported in and prestressed to bear against, on one side, an adjustable spring support (48), which is located inside the housing and remains stationary during the rocking motion, and, on the opposite side, the end (52) of the arm (38) located inside the housing. By this arrangement there is exerted on the said end of the arm a controlled force directed away from the spring support (48) for the purpose of stabilizing the arm in its two positions. The spring support may consist of a rocker, the position of that part (56) of the rocker in which the spring component is supported being adjustable against an adjusting means (16) with respect to the nearer end of the arm to permit alteration of the prestressing of the spring component. The adjusting means consists of a cover (16) with an annular collar (30) of thickness varying along the extent thereof. The collar rests against the inside of the ring flange (32) of a base (12), which is rotatable with respect to the said adjusting cover.

Abstract: A shock suppressing device adapted to be attached to the aft end of a shoulder fired rocket launcher. The device comprises an elongated, flexible, tubular member formed of a compressible, permeable fabric. The member has an expanded diameter substantially greater than the diameter of the exhaust opening in the aft end of the rocket launcher tube. In one embodiment, the rear of the member is covered with fabric so that the member forms a bag covering the exhaust opening of the rocket launcher. The member has a sufficient expanded volume to contain the exhaust gases generated by a launched rocket thereby confirning these exhaust gasses and their associated flash, smoke and blast wave. The blast wave is dissipating by forcing it to penetrate the member. In another embodiment, the rear of the member is open thus causing the generated shock wave to be accelerated rearwardly while being dissipated. The full expansion of the shock wave is not allowed until the shock wave has been reduced significantly.

Abstract: The object to be wrapped is deposited on thin aluminium foil which extends over the mouth of a forming device comprising an annulus and a plurality of resilient blades each fixed at one end to the annulus and converging at their other, free ends towards a first half mould having a hemispherical cavity coaxial with the annulus. A push rod is advanced axially of the preforming device to push the object and the aluminium foil between the resilient blades, making the foil adhere to the leading surface of the object and effecting a first moulding of the aluminium foil around the trailing surface of the object. The partially wrapped object is expelled from the forming device the blades of which close to effect a second moulding of the aluminium foil over the trailing surface of the object, forming a rear projection in the form of a tail constituted by that part of the aluminium foil which does not adhere to the object. The object expelled from the forming device is transferred into the cavity of the first half-mould, while a second half-mould is having a hemispherical cavity facing the first half-mould is displaced axially of the first half-mould through the forming device so as to squash the rear projection of aluminium foil against the object.
