Abstract: Abstract of the Disclosure It is known to add polymethacrylates and other polyolefins to lubricating oils to improve their temperature-viscosity properties and lower their pour point.  However, the effective treatment with polymethacrylates is expensive and polyolefin additives do not lower the pour point.  The present invention seeks to overcome these drawbacks by providing a process for the preparation of lubricating oil additives, which additives comprise a solution in a lubricating oil of a polymer composition prepared from (A) at least one olefin selected from ethylene, prolylene, butylene and isobutylene, and (B) at least one methacrylate ester wherein the alcohol moiety contains 8 to 18 carbon atoms and, if desired at least one further copolymerisable monomer in a minor amount based on the total weight of (B); the polymer composition comprising 20 to 50% by weight of monomer units of (A) and 50 to 80% by weight of monomer units of (B) the polymer composition being present in the said solution in an amount of 20 to 55% by weight of the solution; the process comprising polymerising monomer(s) (B) in a solution in lubricating oil of a homopolymer of copolymer of the said at least one olefin as defined under (A) wherein the initial viscosity of the solution, prior to polymerisation, does not exceed 15,000 centistokes at 100°C, and subsequently adding to the solution a further amount of a homopolymer or copolymer of at least one olefin as defined under (A) which olefin(s) may be the same as or different from to the olefin(s), the homopolymer or copolymers of which was initially present in the solution, the further amount of the homopolymer or copolymer being added in sufficient quantity to provide a polymer composition having the above-defined proportions of monomer units of (A) and (B).

Abstract: DRIVE MACHINE MOVING MAGNETIC DISKS ONLY PARTIALLY THEREIN FOR DATA TRANSFER     Abstract of the Disclosure A machine operative to sequentially pull jacketed flexible magnetic disks (which may be termed "diskettes") into a data transferring position in the machine directly from a carriage or from a magazine carried by the carriage and to return the diskette back into the carriage or magazine.  The jackets of the diskettes are square; and the carriage and the magazine are provided with flat sided, flat bottomed store grooves for holding such diskettes.  The machine is likewise provided with a diskette receptor groove having flat sides and a flat bottom and holding a diskette in its data transferring position in the machine.  The flat sided and bottomed grooves cooperating with the square diskette jackets prevent a binding or jamming of the diskettes as they are moved from the carriage or magazine into the machine and back again, and the movement of a diskette is only partially out of a store groove in the carriage or magazine so that the diskette is certain to be moved completely back into its original store groove in the carriage or magazine after a data transfer has taken place and so that the machine is shortened to this extent.  The carriage has a few store grooves for a few diskettes desired to be individually used, and the magazine has a greater number of diskette store grooves for a group of diskettes desired to be used together.

Abstract: MACHINE TOOL COOLANT SYSTEM                     ABSTRACT OF THE DISCLOSURE    A coolant system for a machine tool is disclosed. Sockets on the machine tool are equipped with check valves biased to a closed position.  When a tool is inserted into a socket, an actuating member opens the check valve to enable coolant to flow through a conduit in the tool to the cutting edge of the tool.  Tools whose cutting edges do not require coolant are not equipped with the actuating member.  In addition, a distributor is provided for use in the coolant system of a machine tool having a turret.  The distributor is mounted on the turret and is coaxial with the axis of rotation of the turret.  Coolant is piped into the center of a distributing member having an outlet on a cylindrical side surface.  A receiving member has a cylindrical chamber in which the distributing member is rotatably disposed.  The receiving member has a plurality of radially disposed passages which lead from the receiving member to the tool receiving sockets on the turret.  Coolant flows only to a tool in the working position because only the passage leading to that tool is aligned with the outlet of the distributing member. As the turret is rotated to index a different tool to the working position, coolant is ported to the passage leading to the tool then in the working position.

Abstract: AN APPARATUS USED IN THE TREATMENT   OF A CONTINUOUS STRIP OF METAL    Abstract of the Disclosure An apparatus used in the treatment of a sheet of metal with-out the aid of conventional sprays and flooding nozzles normally used in the application of the metal treating liquid and support rollers and squeeze used for contacting and guiding the sheet of metal through successive baths of the metal treating liquid and preventing the carryover of liquid between the treatment tanks of the apparatus.     In the apparatus of the invention, a sheet of metal is guided in a horizontal pathway between successive treatment tanks or units having horizontally elongated chambers with two rows of oppositely disposed and horizontally aligned nozzles between which the sheet of metal travels on a liquid bed that is created by the nozzles which are designed to direct streams of liquid, under pressure, against the traveling metal sheet at angles that are substantially less than 90° relative to the plane in which the metal sheet travels.     A unique liquid seal and conventional blowoff device are utilized at each opening through which the traveling metal sheet enters and exits the various chambers, as a means of maintaining the liquid within the chamber and preventing it from being carried away by the traveling metal sheet into an adjacent chamber where the appearance of such liquid may have a deleterious affect upon the process being carried out in that particular chamber. The individual units are also free of brushes and other such devices which are normally used to aid in the cleaning of the sheet of metal.

Abstract: ABSTRACT         The invention relates to radio therapy apparatus comprising an electron accelerator having a target and a collimator for limiting the X-ray cone. In the use of such electron accelerators, the radiation load of the patient is increased in an undesirable manner by neutrons in addition to the therapeutically desired roentgen quanta. To reduce the neutron level the invention provides that the edge zone of the collimator facing the target is made of a material of low effective cross-section for (gamma, n) processes. The dimension of this edge zone material approximately corresponds to the half-value depth of the X-radiation in this material.
