Abstract: ABSTRACT OF THE DISCLOSURE     A process is provided for producing a new series of fusidic acid derivatives, and salts and easily hydrolysable esters thereof.  The new fusidic acid derivatives have the general formula         I in which Q1 and Q2 stand for the group     or oxygen, A represents oxygen or sulphur, and R1 stands for a substituted or unsubstituted straight or branched alkyl radical having from 1 to 12 carbon atoms, or a substituted or unsubstituted alkenyl or alkynyl radical having from 3 to 6 carbon atoms, or an unsubstituted or substituted cycloalkyl radical having from 3 to 7 carbon atoms in the alicyclic ring, or an unsubstituted or substituted aralkyl or aryl radical, or a heterocyclic radical having 5 or 6 ring atoms and containing oxygen, sulphur and/or nitrogen atoms.    In formula I the dotted line between C-24 and C-25 indicates that the carbon atoms in question are connected by either a double bond or a single bond, and the asterix at C-20 indicates that the compounds exist in two diastereomeric forms.  Pure diastereomers  , well as mixtures of these are prepared according to the inverted process.  Such compounds possess antibacterial properties and show further interesting antimicrobial and pharmacokinetic  properties.

Abstract: PROCESS FOR REDUCING THE MERCURY CONTENT OF INDUSTRIAL WASTE           WATERS             Abstract of the Disclosure:      The invention deals with the reduction of the mercury content of industrial waste waters, especially those from a chlorine-alkali electrolysis using the amalgam process.       According to the invention all mercury present in the waste water is converted to the form of Hg++ ions by adding chlorine. Subsequently Fe++ ions are added. The pH of the solution is raised until a redox potential of from - 0.1 to - 0.8 volts, relative to the normal hydrogen electrode, is obtained. The mercury precipitated and the iron oxide hydrate formed may be filtered from the waste water. Residual mercury contents in the filtrate of about 50 mg/m3 may be obtained.

Abstract: ABSTRACT OF THE DISCLOSURE          A process for making a laminated pneumatic tire is disclosed.          The tire may be free of reinforcing fabric and is made of a substantial number of alternating layers of high-modulus and low-modulus polymeric material.  The process includes applying to an annular form a first continuous layer having a viscosity less than 100,000 centipoises at 30°C, then partially curing the layer, and thereafter applying to the first layer a continuous layer of a second polymeric material.  This process is then repeated to form a laminate.  The alternating hard and soft layers provide the tire with a necessary durability and resistance to flex cracking.  The tire may contain low-modulus polymeric layers with a Young's flexural modulus from 100 to about 5000 per square inch.  The high-modulus layers of the tire may have a Young's modulus from 3000 to 50,000 or higher.          The laminate is heated and cured while it has a general toroidal shape.          The cured material of each layer has a Shore A durometer hardness of at least 20.  The high-modulus layers have a tensile modulus at 10 per cent elongation in any direction which is at least twice that of the low-modulus layers.

Abstract: ABSTRACT OF THE DISCLOSURE         The packing is in the form of a surface defining a space which is at least partially enclosed thereby.  A finger is formed from the surface and extends into the space, the surface of the finger making an angle of between 4° and 45° with the axis of flow of gas passing through the space.  In a preferred form the surface is cylindrical and portions of the cylindrical surface are cut therefrom to form fingers which are bent inwardly towards the axis of the cylinder to provide liquid vapor contact surfaces in the interior of the cylinder.  At least some of these surfaces are bent at an angle which is between 4° and 45° to the axis of the cylinder to provide turbulence in the gas flowing parallel to the axis of the cylinder so as to increase the in-teraction between the flowing gas and the wetted surface of the finger.

Abstract: ABSTRACT     A control system for a shoe upper conforming machine, more especially a pulling over and toe lasting machine, includes a computer control which supplies control signals sequentially, according to a programmed instruction, to actuating means for the various operating elements of the machine. In particular, the release of the grippers is controlled in relation to the movement of the wiper means. The actuating means for the wipers has a signal device associated therewith which each gripper has a reference signalling device associated therewith. The computer control compares the value of the signal from the signal device associated with the actuating means with the values of the signals from the reference signalling devices. Upon matching of signals, a control signal is caused to operate the gripper actuating means to release the gripper associated with the matched reference signalling device .  Furthermore, the power supply to the actuating means for effecting gripping and pulling is independent of that for the actuating means for wiping over and securing the lasting margin to the insole, the arrangement being such that the power supply to the latter is operatively connected only after the operation of the former is completed so that, regardless of any control signals passed to the actuating means for the latter, no wiping can take place until gripping and pulling is completed .

Abstract: ABSTRACT        A microcomputer based pinball game controller having three distinct memory devices for control of game operation. A first memory device utilizes machine language programming instructions for control of the game independent of specific game rules thus lending itself to mass production for a large number of different amusement games. A second memory device employs a higher level language set of instructions for controlling the game in accordance with specific rules of the game. A simple set of higher level language instructions renders this second memory device conducive to game designer programming and easy modification of the game rules, a marketing procedure traditionally used in the design of the electromechanical pin all machine. A third memory device, employing a matrix of operator adjustable binary switches easily accessible to the exterior of the game, permits a degree of game mode control, such as the degree of playing difficulty and the number of games for a given coin denomination.

Abstract: ABSTRACT OF THE DISCLOSURE           A tube bundle heat exchanger with baffles is disclosed wherein a tube bundle is housed within an inner casing which is acted upon from both the inside and the outside by a heating medium.  The inner casing is not stressed by pressure caused by the heating medium since the medium flows both within and without the casing.  The part of the circumference of each baffle which is in contact with the inner casing is tightly connected to the inner casing in order to prevent leak flows.  Adjacent heat exchanger tubes of the tube bundle are separated from one another by a zigzag-shaped dividing wall.  The dividing wall forms space-economical rerouting channels with the baffles.  The tubes of the tube bundle are located parallel to the longitudinal axis of the heat exchanger, and therefore longitudinal in the longitudinal rerouting channels.  The heating medium which flows through the rerouting channels flows across the tubes producing favorable heat transfer conditions.

Abstract: Abstract Glass is thermally treated by contacting the glass, when it is hot, with a gas-fluidised mixture of particulate materials, at least one of which has gas-generating properties when heated by the hot glass.  The materials are mixed in selected proportions which impart to the mixture a thermal capacity and flowability which are such that a required thermal treatment is achieved.  The method is suitable for the thermal toughening of glass sheets for vehicle windscreens.
