Patent NL-7417034-A (NL)
Title: Explosive pressure chamber to convert materials properties - particul-arly graphite into a conglomeration of shiny crystals of great hardness
IPC: F42D3/00
Filed: 1974-12-31
Abstract: In order to change its properties a mass of material is converted by explosive pressure between a coaxial pair of hollow, explosive charges which are fired simultaneously within an explosion chamber inside a massively strong block. Residual gases from the conversion should be evacuated at a controlled rate, e.g. by way of vent passages initially blocked with fusible plugs of differing characteristics which give way progressively as the explosion heat and pressure rise.

Title: Steriliser for cylindrical containers - comprises horizontal steamer drum with radial compartments and with dished ends
IPC: A23L3/02
Filed: 1977-08-26
Abstract: Tin cans, bottles and similar cylindrical containers are sterilised in a horizontal steamer drum with dished ends. The inside of the drum consists of radial compartments open at the outer end and mounted on a rotating shaft which may be driven in either sence by a motor external to the drum. A casing on the outside of the drum is equipped with two openings, one for charging the drum with tins and the other for emptying it. The openings are sealed by means of slide valves which prevent the egress of steam. The outer end of each radial compartment is pref. equipped with a tumble lever stop which is normally closed but may be opened by means of a piston operated trigger in the wall of the drum. The arrangement is such that the drum is filled by rotating it in a clockwise direction and emptied by rotating it anticlockwise. The drum provides an economic, semi-continuous sterilisation unit for cans.

Title: Automatic switch for curtain drive motor - has traction cord wound to form loop and actuate slider which separates sprung contacts
IPC: A47H5/02
Filed: 1978-04-13
Abstract: The automatic switch controls the operation of an electric motor driving a traction cord (6). The switch has a slider to separate two blade-sprung (15) contacts. The slider is displaced by the traction cord as it reaches the end of its run, and may be adjustable to accommodate curtains of different weights. The slider (5) is traversed by two vertically aligned runs of traction cord (6) which pass below to loop through a triangular three-wheel friction-drive system. When the cord is fully extended, either curved run straightens t displace the slider and, thus, operate the switch, the slider is T-shaped in plan with a forked leg which locates between the blade springs (15).

Title: Motor vehicle safety seat - has latch and lever unit and tilts backwards automatically on sudden deceleration
IPC: B60N2/42
Filed: 1979-04-23
Abstract: The vehicle safety seat comprises a frame fixed to the floor and adjustable in the vehicle lenghtwise direction and lockable, together with a backrest adjustable within limits for angle in relation to the seat cushion and also lockable. A main support is coupled to the backrest, and a detchable safety belt is included. On sudden deceleration, components (9, 10, 11) movably coupled between the frame (1) and a mounting plate (4) for the seat cushions (5), and supporting the plate, are actuated. A mechanism in the frame which reacts to sudden deceleration releases one or more of these components from the rest position. This causes the seat cushion with backrest to tilt backwards while maintaining the angle between them so that the seat forms a supporting surface absorbing the shock for the lower part of the body of the occupant, who is enclosed by the safety belt (8).
Patent NL-7906789-A (NL)
Title: Interference electrotherapy appts. - uses two modulated phase-locked high frequencies to reduce dead-zones in treatment area
IPC: A61N1/32
Filed: 1979-09-12
Abstract: An earlier form of electrotherapy appts. produces nerve stimulation by the low frequency interference between two separately applied high frequency oscillations. A disadvantage is that there are 'dead-zones' in the area of tissue to which the treatment is applied. This can be partially overcome by using two modulated signals which have a fixed phase relationship. The low frequency source (L) is used to modulate the two high frequencies (H1 and H2), which are maintained at the same frequency and a fixed phase difference by a phase-locking device (PHI). The two modulated outputs are applied to the patient via four separate electrodes. A system using a common high frequency source and two phase-locked low frequency circuits is equally effective.

Patent NL-8403818-A (NL)
IPC: G11B20/18
Filed: 1984-12-17
Abstract: @ During the decoding of a code word of an information stream which is protected by a symbol-correction code, first all channel symbols are demodulated; a first indicator flag then indicates whether or not the demodulation is reliable. All code symbols of a code word are subsequently collected, after which the decoding operation commences; the code word is corrected if possible and necessary. The reliability of the correction is indicated by a second indicator flag. When the correction is unreliable, the stream of channel symbols is addressed again. During the latter operation only unreliably decoded code symbols are replaced by new code symbols in order to enable renewed decoding of the code word thus modified.
