Abstract: Abstract The invention concerns writing on light anodized aluminum surfaces.  Substances which change color in contrast to their surroundings when acted upon by a laser beam of high energy density are added to the anodized layer.  According to one proposal in the invention, this can lead to a chemical reac-tion of these substances with the anodized layer. Examples of the substances added to the anodized layer are glucose hydrate, cobalt acetate, zinc acetate or zinc nitrate, lead carbonate or chromium carbonate, ammonium vanadate, nickel nitrate or nickel acetate.

Abstract: ABSTRACT           A wireline supported mechanically operable packer device for use in a drill string casing and attached core drill bit raised off the bottom of a borehole and testing the formation below has a housing adapted to engage an arresting internal shoulder of the core drill bit.  A hollow inner mandrel slideable in the housing has attached thereto a packer seal cup an O-ring seal expanded weight means and wireline means moveable between stops determining the extended and contracted positions thereof relative to the housing.  Upon lowering the wireline and weight means that attached inner mandrel continues its downward movement relative to the arrested housing and toward the contracted, locked sealing position, and thereby actuates means locking the housing to the casing, ejects the initially contracted and stored packer seal from an end chamber of the housing whereupon it expands into sealing engagement with the borehole wall below and the expander means expands the O-ring against the internal surface of the casing.  Fluid under pressure is then pumped through casing and inner mandrel to test formation after which the packer device can be retrieved and hoisted out by wireline whereby a reverse sequence of movements of the various elements occurs during return of the device to its initial extended unlocked non-sealing position.

Abstract: Abstract of the disclosure The invention relates to a process for the prepa-ration of oligonucleotides by the following steps: reaction of a nucleoside with a phosphine derivative, reaction of the nucleotide derivative thus obtained with a nucleoside bonded to a polymeric carrier, oxidation of the carrier-bound nucleoside-nucleotide thus obtained with formation of phosphotriester groups, blocking of free primary 5'-OH groups, elimination of a protec-tive group from the terminal 5'-OH group, where approp-riate single or multiple repetition of the abovemen-tioned steps to introduce further nucleoside phosphate or oligonucleoside phosphate units, and cleavage of the nucleoside-carrier bond and, where appropriate, elimina-tion of all protective groups present in the oligonucleo-side phosphates.  The phosphine derivative used is a compound of the general formula III                 (III) in which X and L can react with OH groups of the sugar units in the oligonucleotides, and R3 is a protective group which can be liberated by  .beta.-elimination.

Abstract: ABSTRACT OF DISCLOSURE         A fuel control system for use in supplying gaseous fuel from a high pressure source to an internal combustion engine which has an air/fuel intake through which air and gaseous fuel is supplied to the engine and an air/fuel intake manifold in which variations in the vacuum are indicative of engine loading conditions. The system comprises; a pressure regulator, a flow control valve, a control for measuring the speed of the engine, a modulator for modulating the fuel supply and a pressure control device communicating with said pressure regulator to increase or decrease the pressure in the gaseous fuel output in response to the receipt of a signal from the modulator.  The a pressure regulator receives pressurized gaseous fuel from the source and serves to maintain a constant pressure in the discharging fuel for a given engine speed regardless of flow rate and to increase or decrease the pressure in the discharging gaseous fuel in response to an increase or decrease in engine speed.  The flow control valve is operable to control the flow of gaseous fuel in response to engine loading conditions regardless of engine speed.  The modulator communicates with the output from the pressure regulator to measure the pressure of the fuel supply to the flow control valve.  The modulator also communicates with the control means and cooperates therewith to generate a signal which is indicative of an undesirably low pressure or a signal which is indicative of an undesirably high pressure and one or other of these signals is communicated to the control. The pressure control communicates with said pressure regulator to increase or decrease the pressure in the gaseous fuel output in response to the receipt of one or other of said signals.

A fuel supply system is provided for supplying gaseous fuel under pressure to each flow control valve.     A sensor is provided for determining when diesel fuel is being injected into each cylinder and generating a control signal which indicates when fuel injection occurs and communicates the control signal to the fuel control valve associated with the cylinder which is next in the firing order to that receiving diesel fuel such that the control signal is effective to open said flow control to admit gaseous fuel to the input air of said cylinder which is next in firing order.

Abstract: ABSTRACT:           In order to simplify the programming or repro-gramming of the available channel frequencies in a fre-quency synthesised multichannel radio apparatus, all the available frequencies are stored in a PROM (40) which acts as a look-up table.  The addresses of those locations in the PROM (40) which are available to a user are stored in an electrically alterable storage means (42), such as an EAROM or a E2PROM.  In normal operation a channel selector (24) selects a particular channel in the storage means (42) which in turn addresses predetermined locations in the PROM (40).  If it is desired to programme/reprogramme the channel frequencies available to a user then a data transfer unit (34) which has been preprogrammed with the new channel frequencies is connected to the storage means (42) and the new sequence of channel frequency addresses is stored in the storage means.  The reprogramming can be done with the apparatus in situ which saves time and avoids opening-up the apparatus.

Abstract: ABSTRACT          A process is described for the formation of high purity alumina from aluminas such as Bayer Process alumina trihydrate (gibbsite) which contain both acid-soluble and -insoluble impurities, notably soda and silica.  The solid hydrated alumina is reacted with a stoichiometric quantity of concentrated HC1 to form a reaction product comprising of dissolved aluminum chloride and solid aluminum chloride hexahydrate  (ACH).   The  acid  and/or  aluminum  chloride concentration  of  the  solution  is  then  adjusted  (as  by water  addition)  to  dissolve  the  solid ACH  and  form  a solution at or near saturation in aluminum chloride, but with  the  remaining  solid  materials  undissolved.    The solution is then subjected to solid/liquid separation to eliminate  the  insoluble  impurities,   such  as  silica. Thereafter,  the concentration is again adjusted to cause the ACH to crystallize and precipitate preferentially to the  soluble  impurities,   following  which  the  ACH  is recovered  as  a  solid  and  calcined  in  a  single  or multistage  calcination  to  high  purity  alumina.   The purified  products  find  use  in  the  specialty  ceramics field, as synthetic sapphire, translucent tubing or other applications in which alumina must meet SPA specifications.
