Title: Sweet aspartylaminoacid esters prepn
IPC: A23L27/30
Filed: 1970-05-19
Abstract: Aspartylaminoacid esters are prepd. by reacting N-carbobenzoxyaspartic acid anhydride with an amino-acid ester salt in an inert polar solvent while adding an amount of base at least equivalent to the ester, isolating the N-carbobenzoxy-alpha- and/or beta-aspartylaminoacid ester and removing the protecting gp. Compared with the known method, this gives higher yields, suppresses the formation of diketopiperzines and gives products of high optical purity. The products are useful as sweeteners in foods, drinks and pharmaceuticals.

Title: Snap connector for permanently joined parts - parts of different elasticity with softer part are pressed into shape by harder parts
IPC: F16B21/06
Filed: 1973-11-05
Abstract: The connector comprises two mating cylindrical parts with shoulders, and one or both is of elastic material. The protruding coupling portions of one part of elastic material, and those on the other of less elastic material. The shoulders on the latter extend in a screw pattern round it. The pitch of the thread and the difference in elasticity between the two parts are so selected that the coupling portions of the first part are pressed into the screw form of the second one when they are fitted together, and so that they can be unscrewed from each other. Both parts can be of plastic, and threaded, the two threads being of different pitch.

Title: Heater, cooler and mixer, esp. for sugar boiling - forces material through gradually diminishing annulus between exchanger surfaces
IPC: A23G3/02
Filed: 1976-11-08
Abstract: A device for the heating, cooling or mixing of fluids has a closed cylindrical housing with an inlet in its mantle close to one end and an outlet in its other end wall. Inside the housing and coaxial with it, a body arranged symmetrically is free to rotate on its axis. Between the body and the housing there is an annular cavity which diminishes gradually in size in the axial direction from the inlet to the outlet end. Around the housing and inside the rotary body a heating and/or a cooling circuit is provided. The annular cavity between housing and body diminishes gradually from about 4 mm at the inlet to a min. value of is approx. 1 mm at the outlet. The body can be rotated at a speed of from 300-3,000 r.p.m. This speed is variable. An auxiliary inlet is provided in the wall of the housing for the mixing of two fluids. The device works quickly and efficiently whilst giving good control over the temp. so that discolouration of the prod. is not brought about or that unwanted crystallisation takes place during cooling. The amt. of water used can be reduced to that necessary to give the required final humidity.
Patent NL-7707854-A (NL)
IPC: B24B5/36
Filed: 1977-07-14
Abstract: A method and apparatus for forming solid bodies by removing material from solid workpieces. A workpiece is situated between oppositely rotating tools which remove material from the workpiece, these tools having hollow interiors facing each other and each conforming to the configuration of one half of the finished body. The hollow interiors of the tools have teeth for removing material from the workpiece, and while the tools are rotated oppositely the distance therebetween is due so that from the workpiece a body is gradually formed, this body finally becoming almost completely enclosed within the hollow interiors of the tools, whereupon the latter have the distance therebetween increased so that the body formed thereby can be removed. These tools are adapted to form from a workpiece bodies of full circular or ring-shaped configuration, and the hollow interiors of the tools are provided with raised teeth similar to file teeth, for removing material from a workpiece. In addition, each tool is formed with openings extending outwardly from its hollow interior so that the material removed by the tool from the workpiece can travel outwardly through these openings.

Patent NL-8702825-A (NL)
Title: Thermostat safety cut=out for electric kettles etc. - inhibits reconnection until temp. has fallen and power is switched off until positive action is taken
IPC: H01H1/50
Filed: 1987-11-25
Abstract: The thermostat is used in electrical heating equipment, typically electric kettles, where once a desired temp. has been reached, the power should not be re-connected to the element without a decisive action by the user. Power to the element flows through contacts which are held together by a bi-metallic strip (5) until the temperature exceeds the required switch-off level. When the main contact is broken, a much smaller current continues to flow through a resistive bridge across the contacts. The power dissipated by the resistive bridge provides local heating which ensures that the bi-metallic strip keeps the contacts apart until the current source is broken. The bridge may be a resistive paste (9) coating a pin (4) alongside the strip, or a plate under the strip.

Patent NL-9201423-A (NL)
Title: New operating method for kidney and gallstone lithotripters
IPC: A61B17/22
Filed: 1992-08-07
Abstract: The invention relates to a completely new operating method and set-up compared with existing kidney and gallstone lithotripters. With an existing lithotripter, the stone is bombarded with shock-waves from one direction which yields extremely poor results, namely 2500 to 7000 shocks on one stone, and repeated treatment may be required. The cause of this performance is clear; the stone that is being treated is not restrained by the softer parts of the kidney or gall bladder and vibrates away with every shock. The invention overcomes these disadvantages completely. The stone is bombarded with shock-waves from two opposite directions. The shock-waves reach the stone simultaneously, preventing the stone from vibrating away so that the stone is pulverised between the two shock-waves, providing an optimal result many times superior to existing methods. The many major benefits are obvious and include the cost and time savings of lithotripsy treatment. In addition, the invention can reduce human suffering by reducing the number of surgical procedures needed. <IMAGE>
Patent NL-9400152-A (NL)
Inventor: MIDDENDORF JOHANN GERHARD
IPC: F24F12/00
Filed: 1994-02-01
Abstract: The invention concerns a device where used ventilation air is used to bring fresh outside air to the desired temperature and next to convey to the to be ventilated space. For this purpose is made use of heat regenerators (6, 7) which serve with the help of a change-over valve (5, 15) intermittent for heating or cooling of the ventilation air. Characteristic is that the used air by means of heating or cooling by water atomisers (12) is brought to such a temperature that the heat regenerators (6, 7) after the passage of the used air attain the desired temperature. After a cycle change the fresh outside air is brought to the desired temperature by the heat regenerators (6, 7). A variant of the invention shows the atomisers (12) mounted to the valve (5, 15) where the atomisers (12) turn 180 DEG  at the changing of the cycle.

Title: Modification of the growth repair and maintenance behaviorof living tissues and cells by a specific and selective change in electrical environment
IPC: A61N/
Filed: 1980-07-04
Abstract: The growth, repair and maintenance behaviour of living tissues and/or cells can be modified beneficially by the application of a specific electrical information. This is achieved by applying pulse waveforms of voltage and concomitant current of specific time-frequency-amplitude relations to tissue and/or cells by a surgically non-invasive device through use of a varying electromagnetic field which is inductively coupled through direct induction into or upon the tissue and/or cells under treatment. The information furnished to the cells and/or tissues by these signals is designed to influence the behaviour of non-excitable cells such as those involved in tissue growth, repair, and maintenance. These growth, repair and maintenance phenomena are different from those involved in excitable cellular activity (e.g. nerves, muscles, etc.), particularly with respect to the type of perturbation required. Thus, the voltages and concomitant currents impressed on the cells and/or tissues are at least three orders of magnitude lower than those required to effect cellular activities such as cardiac pacing, bladder control, etc.
