Patent NL-7105545-A (NL)
Title: High porosity dehydrogenation catalyst
IPC: B01J37/00
Filed: 1971-04-23
Abstract: Self generating catalyst for the dehydrogenation of olefins to dienes and alkyl benzenes to vinyl benzenes is obtd. by mixing a wet paste of a catalyst, based on mainly Fe2O3, but also contg. chromic oxide and K2CO3, with 5 to 30% wt., pref. 20% wt. of polystyrene beads of diam. 0.1 to 0.5, pref. 0.3 mm. This mixt. is then extruded to give the final catalyst. This catalyst has much higher porosity which leads to better selectivity and to a lower catalyst consumption per unit of product.
Patent NL-7404265-A (NL)
Title: Membrane filtration in series of units - where the feed is switched periodically to the last unit to cool and clean it
IPC: B01D61/14
Filed: 1974-03-28
Abstract: Membrane filtration is performed in a number of units in series, each unit having several membranes in parallel. After a set time the feed to the first unit is discontinued and the last unit in the series is made the first. The contaminated liquid from this unit is fed to what used to be the first unit. Normally towards the end of the series the amount of fouling and the temperature increase and both factors lead to an increase in microbiological growth rates. Periodically changing the cool, dilute feed to what was the last unit cleans that unit and slows down microbiological growth rate.

Title: Abrasive disc contg. abrasive and binder - and embedded fibre reinforcement having high modulus of elasticity and length
IPC: B24D3/34
Filed: 1978-07-31
Abstract: High strength reinforcing fibres, (I) having length >=10 mm and modulus of elasticity >=1 x 104 kp/mm2, are incorporated in abrasive discs contg. abrasive grains, resin-esp. thermosetting resin binder and filler. The fibre reinforcement may consist of mono-crystal whiskers and/or polycrystalline metal whiskers and/or B fibres, partic. synthetic, inorganic fibres. Fibre adhesion in binder matrix is improved by providing the fibres with a surface coating having a high chemical and/or physical affinity to binder, e.g. by oxidn. Thus, the fibres may be high-strength C fibres, oxidised on surface, or may consist of drawn metal wires, esp. of higher alloyed C steel coated with a primer.

Title: Electrical coffee maker with sensor in water by=pass - has indicator to show that the heater outlet pipe is furred-up by dissolved chalk
IPC: A47J31/58
Filed: 1982-02-18
Abstract: This electrical coffee maker has a cold water reservoir (1), connected to a heating chamber (3). The hot water is forced up the outlet tube (4) from which it runs through a filter holder (6) into the jug (7). The outlet tube (4) has a narrow by-pass tube (10) which has a very restricted opening (5) at the bottom. If the calcium salts in the water have caused excessive furring the opening (5) becomes blocked, and a detector electrode (11) in the top of the by-pass detects that the water in the by-pass does not run away. An indicator circuit (16) activates the detector (11) a short time after the level detector electrode (15) detects that the heating and syphoning process is over.

The heart valve (3) is placed in a holder (2) in the middle of the channel (1). The gas pressures in the reservoirs above the liq. surfaces (7,8) are controlled by gas pressure control units (11,14) which each have a controlled gas input (12,15) and an outlet (16,19). The pressures are continually altered in anti-phase with each other by a motor-driven mechanical system. The frequency of change, typically 10 Hz, can be altered.

Title: CRT in-line electron gun - uses apertured grids between beam generator and screen to produce convergence and prevent coma distortion
IPC: H01J29/51
Filed: 1984-09-20
Abstract: The tube has a target electrode and an electron gun with a first electrode spaced along a central gun axis from the target electrode to produce and direct a number of electron beams towards the target electrode along paths which are initially parallel to the gun axis. At least one of the beam paths is spaced from the axis. A second electrode is spaced along the paths between the first electrode and the target electrode to form a different signal electric field lens positioned in the path of each beam for focusing the beams near the target electrode. The second electrode forms the lens in the one beam path asymmetrically to it to bend that beam towards the gun axis.
Patent NL-8403053-A (NL)
Title: Magnetic head for recording reproducing and/or erasing - has transfer gap merging into contact face in concave region in direction of movement
IPC: G11B15/62
Filed: 1984-10-08
Abstract: The head has a contact face (2) for a flexible magnetic information carrier which can be moved in a direction (V) along the face. A transfer gap (3) merges into the contact face. This gap lies in a region (6) of the latter (2) which is curved into a concave shape in the direction of movement. On either side of this region (6) are regions (7,8) curved into a convex shape in the direction of movement (V). The contact face is curved into a convex shape transverse to the direction of movement. Due to this shape, an information carrier exerts only a low pressure on and near the transfer gap.

The valve member is movable to a partly closed position from a middle released position by increased fluid flow. The valve member also has a tapered venturi like passage (5) in the same direction as the central passage. Between the member and the seat (1) is a return spring (6). The valve member also contains parallel flow channels spaced at regular intervals around the central passage. When the member is in the position which closes the central passage, these peripherally channels are partly closed by the valve seat.
Patent NL-8602451-A (NL)
IPC: H04R7/26
Filed: 1986-09-29
Abstract: An electrodynamic loudspeaker (1) has a diaphragm comprising a central part (2) and a peripheral part (3), and a voice-coil device (9, 10) coupled to the central part (2). The ratio S2/S1 complies with the relationship 0.5 </= alpha  mu  rho  &Uml&  S2/S1 </= alpha mu  rho  &Uml&  6, where S1 and S2 are the surface areas of the central part (2) and the peripheral part (3) respectively. The ratio m2/m1 complies with the relationship 0.5 </= alpha  mu  rho  &Uml& m2/m1 </= alpha mu  rho  &Uml&  8 where m1 and m2 are the mass of the central part (2) and the voice-coil device (9, 10) and the mass of the peripheral part (3) respectively. Further, the compliance imposed on the diaphragm by the space (6, 6') defined by the diaphragm (2, 3) and the chassis (4) and/or the magnet system (7) is smaller than the compliance of the diaphragm itself (Fig.1). Thus it is possible to realise a car loudspeaker which has a specific dip in its frequency response characteristic P (Fig. 2a), measured in an anechoic room.

Title: EM mechanical, resonator detecting shop lifter - vibrates audibly when exposed to magnetic field
IPC: H03H9/22
Filed: 1989-12-31
Abstract: The application describes various forms of resonator, the common factor being that they are all magnetic circuits made up from pieces of two types (2, 3) of material. The two materials have differing magnetic characteristics and there are air gaps between the different pieces. One of the materials is a permanent magnet of such field strength that the internal field and externally induced field combine to cause a change in the length of the magnetic path through the resonator, with resultant vibration. The various types of resonator include toroids and transformers. @(25pp Dwg.No.1/5)@.
