Patent NL-7606220-A (NL)
IPC: F24D3/14
Filed: 1976-06-09
Abstract: The heater is in the form of a hot water carrying pipe coil supported on a suitable base, such as a sub-floor, and having spaced parallel pipe ducts interconnected by pipe bends. A pair of parallel supporting laths, preferably in the form of flat bars, are fixed on the sub-floor in spaced relation to the opposite side walls of a room to be heated, and circularly curved members are secured to the laths at spacings therealong equal to the spacing between the pipe ducts, the curved members on one lath being staggered longitudinally relative to the curved members on the other lath. The connecting bends of the pipe coil are looped around these curved members, which latter thus serve as a pipe laying gauge. Stop members are secured to the laths in spaced relation to the free ends of the curved members to form, in effect, troughs for the connecting pipe bends. Heat transmitting metal lamellae are secured to the pipe ducts to interconnect adjacent pipe ducts, and these lamellae may be formed with half-shell portions at each end, one overlying a pipe duct and the other underlying the adjacent pipe duct. The lamellae may be formed with alternating rows of depressions and elevations. In hard to heat areas of the floor, the parallel pipe ducts may be arranged much closer together than in the remainder of the floor, as by having a pitch which is one half the pitch of the pipe ducts in the remainder of the floor and, in such case, the curved members in the hard to heat area of the floor have an angular extent of more than 180 DEG  and a radius which is less from that of the curved members in the remainder of the floor. The lamellae may be metal or may be metal powder-containing plastic.

Patent NL-8320166-A (NL)
Title: Profiling of reactor for thermal cracking of hydrocarbon(s)
IPC: B01J3/04
Filed: 1983-06-10
Abstract: In a process for thermal cracking of liq. hydrocarbons, the preheated feedstock is fed to the base of a vertical pressurised reactor having a cross-sectional area increasing with distance upwards. Since the prods. are less dense than the reactants, this profiling tends to preserve a constant linear velocity for the process stream; and the angle of the reactor wall with the vertical axis is pref. chosen, between 2 and 15 deg., practically to achieved this. A constant velocity of the process stream reduces back-mixing, and therefore the relative importance of secondary reactions to produce pitch, coke and asphaltenes. These aims are achieved without fitting perforated plates, which interfere with reactor cleaning.

Patent NL-9101155-A (NL)
Title: Method and device for fast code acquisition in spread spectrum receivers
IPC: H04B1/707
Filed: 1991-07-02
Abstract: Method for code acquisition in a satellite receiver. The biphase-modulated high-frequency carrier transmitted by a satellite is converted via a fixed local oscillator frequency down to the baseband, whereafter the baseband signal is fed via a bandpass filter, which has an adequately broad pass band to allow the baseband signal to pass through, regardless of the Doppler shift in the satellite signal, to a detector unit, in which the baseband signal is subjected to an edge detection operation. This results in a modified baseband signal, of which at least one parameter is dependent on the occurrence of edges in the baseband signal. In the receiver, a duplicate code is furthermore generated which is likewise subjected to a similar edge detection operation resulting in a modified duplicate code. The modified duplicate code and the modified baseband signal are correlated with one another in order, depending on the extent of the correlation, to generate instruction signals for a search control unit which supplies shift pulses to the duplicate code generator until the detector receives an adequate signal.
