Title: Process for the microbial production of amino acids by boosted activity of export carriers.
Inventor: VRLIJC MARINA
IPC: C12P13/08
Filed: 1998-06-22
Abstract: The invention pertains to a process for the microbial production of amino acids. The process in question involves boosting the export carrier activity and/or export gene expression of a micro-organism which produces the desired amino acid. According to the invention, it was found that a single specific gene is responsible for the export of a given amino acid, and on that basis a process for the microbial production of amino acids, involving the controlled boosting of the export gene expression and/or export carrier activity of a micro-organism which produces the amino acid in question, has been developed for the first time. The boosted expression or activity of the export carrier resulting from this process increases the secretion rate and thus increases transport of the desired amino acid.

Title: Optical fault detector for glass production
IPC: G01N21/896
Filed: 1969-12-12
Abstract: Optical faults in a moving continuous sheet of glass are indicated by using a light source illuminating part of the glass, reflecting the light in a mirror, so that faults in the glass deflect the light beams, which deflection is sensed by a photo-cell, placed to receive the light path of the light going through the glass towards the mirror which light bundle is deflected across the direction of the glass. This eliminates the need for more than one light source which might be of different intensities and which would present construction difficulties.

IPC: B63B39/06
Filed: 1982-05-04
Abstract: The bow stabiliser equipment for an ocean going vessel, consists of several hydraulic valves which are hingeable. During a downwards moving phase of the vessel, the valves take up a horizontal position. During an upwards moving phase of the vessel, the valves take up an almost vertical position w.r.t. the ship's keel line.

Patent NL-8901175-A (NL)
IPC: A23P20/12
Filed: 1989-05-10
Abstract: A method for forming a moving, continuous bed which is composed of granular and/or pulverulent flowable material and which is of constant thickness provides an improved uniformity of the bed by collecting material from a first moving bed so as to form a buffer stock, and by subsequently delivering material from the stock in a regular fashion so as to form a second moving bed which is continuous. An apparatus for carrying out this method comprises a belt capable of being passed through by said material. The material can be moved with the belt over a guide plate situated beneath the belt. In order to prevent too little material being present locally during brief interruptions in the supply of the flowable material and in order to prevent the material being compressed and pulverized in the event of an excessively large supply, a buffer is provided for the material, the discharge opening of which buffer is situated near and above the guide plate. The buffer has an overflow. The material is thus fed via the buffer onto the belt. Provided the buffer remains filled, it is capable of compensating automatically for fluctuations in the material supply.

Title: Fire-resistant window
IPC: E06B5/16
Filed: 1991-11-11
Abstract: Fire-resistant window consisting of an aluminium frame with a front and back section, 1 and 3 respectively, with glass 2 in between. The beads of the front and back sections have elongate cavities 10, 11 and 12 which are filled with water-saturated, strongly water-absorbing material such as calcium aluminium silicate (zeolite), which is stable, i.e. retains the water in the saturated state, up to a temperature of between 50 degree C and 250 degree C and which, in the saturated state, does not attack aluminium. The fire resistance is considerably improved by the use of the water-absorbing material, and is improved even further by puttying the glass against the back profile, using putty which can withstand a temperature 400 degree C. <IMAGE>
