Patent NL-7201566-A (NL)
IPC: B03D1/16
Filed: 1972-02-07
Abstract: In the purification of liquids by flotation, a mixture of gas and liquid is subjected to sufficient pressure for the gas to dissolve in the liquid and form a solution of the gas and the liquid. The solution of gas and liquid without any substantial change in pressure is introduced at a low velocity to the body of polluted liquid in a flotation tank. Initially no gas bubbles are formed. As the solution rises slowly in the tank and it is subjected to a gradually lower pressure, gas bubbles are formed in a gentle manner. Due to the slow rate at which this takes place the gas bubbles will be very small. Since a great quantity of gas is dissolved in the liquid, a large quantity of gas bubbles will be formed. All of these factors contribute to an effective purification of polluted liquids by flotation.

Title: Hydrotreatment of heavy pyrolysis feedstocks - used for prodn of light olefins
IPC: C10G69/06
Filed: 1972-12-18
Abstract: Hydrocarbon feedstocks (b.pt. 400-1100 degrees F) are pretreated before being pyrolysed in a process in which a preliminary selective hydrogenation (without cracking) is carried out in the presence of a Group VIB and/or Group VIII metal catalyst at 640-800 degrees F (pref. 700 degrees F), LHSV 0.5-3.0 (pref. 1.6) and a press. of 750-1250 psig or 1250-3000 psig (pref. 2500 psig), the former press. resulting in an increased aromatic content of the pyrolysis by-prods. and the latter press. giving an increased 1,3-butadiene content of the pyrolysis by-prods. The catalysts used (generally supported on alumina) are chosen from sulphided Ni-Mo, Co-Mo, or Ni-W or Pd. The pref. feedstocks for the process have API gravity 18-25, total aromatics content 20-60% (pref. 43% for aromatics prodn. and 30% for 1,3-butadiene prodn.) and mol. wt. >180. The controlled hydrogenation stage avoids the problems associated with the pyrolysis of high sulphur content and high aromatic content feedstocks in the prodn. of light olefins, and also optimises amts. of aromatic or 1,3-butadiene by-prod.

Title: Pre-fabricated pile for building foundation - has longitudinal reinforcing rods and diverging drive in point
IPC: E02D5/30
Filed: 1975-04-01
Abstract: Building foundation pile may be prefabricated and consists of a shank with (diverging) broadened point. The point in longitudinal cross-section is normally trapezium shaped with the greatest width at the bottom. The incorporated longitudinal reinforcing rods run partly parallel with the shank, then divergent to follow the outer divergent edge of the pile point.

Title: Screwdriver blade protecting collar - has tip protruding from sleeve with locating shoulder and locking ring
IPC: B25B15/00
Filed: 1977-08-05
Abstract: A screwdriver is fitted with an accessory to prevent damage to or scratching the surface of e.g. a panel which is to be secured by the screws. The shank of the screwdriver, which may have a square section end (1) remote from the tip, for a driving tool, is enclosed by a sleeve (2). The tip (4) protrudes only sufficiently to engage the screw head. Thus, the end of the sleeve tends to protect the surface of the panel. The screwdriver shank may include a larger diameter portion (7) to fit inside the top of the sleeve, to fit against a locating shoulder. A locking ring (9) can be fitted between them. In alternative designs, the sleeve can have a bell mouth, and may be flange at the end near the tip.
Patent NL-8020420-A (NL)
Title: Variable current pulse mode battery charger - has thyristor regulating current of applied pulses and variable pulse duty cycle to permit high current charging
IPC: H02J7/00
Filed: 1980-11-06
Abstract: The battery charger is suitable for dry cells and accumulators, and produces a pulsed output which allows a gradual discharge in between each charging pulse. This permits high-current charging without the risk of damaging either the batteries or the battery charger. The charger consists of a controllable rectifier and a variable chopping circuit. The chopper circuit adjusts the gating point of the thyristor, which applies a half cycle of alternating current to the batteries under charge. By controlling the thyristor gating point, the current applied to the batteries may be varied from zero to a maximum. The duty cycle of the applied pulses may also be varied to produce a suitable discharge interval between charging pulses.

The lowermost signature in the stack (4) is pulled partly downwards by one or more suction cups (5), being then gripped by a mechanism (7) travelling to and fro across a conveyor belt (1), and pulled from under the stack onto the latter and released.
Patent NL-8201740-A (NL)
IPC: F42D1/04
Filed: 1982-04-27
Abstract: A percussion-actuated instantaneous or delay detonator transmits a detonation from a first length of low-energy detonating cord (LEDC) transversely positioned adjacent the detonator's percussion-responsive end to a U-shaped segment of a second length of LEDC held with its apex against the base-charge end of the detonator and the arms of the U extending away from the detonator. A directional connector for connecting a U-shaped segment of detonating cord adjacent each end of the detonator has identifiable donor- and receiver-cord-housing sections, e.g., the receiver-cord-housing section has the shape of the head, and the donor-cord-housing section the shape of the butt, of an arrow. A connector adapted to hold receiver LEDC and high-energy detonating cord (HEDC) segments is internally configured to receive nested U-shaped segments of LEDC and HEDC only when the LEDC is adjacent the base-charge end of the detonator.

Title: Sealing body for a pipe joint - has elastomeric seal bonded to fixing sleeve fastened to pipe end
IPC: F16L17/025
Filed: 1985-03-27
Abstract: A sealing body of an elastomeric material may be attached chemically and/or mechanically to a fixing detail of thermoplastic, reacted elastomer or thermosetting material, which is secured to the end of a pipe section to make a reliably sealed connection. The sealing body has a head section together with a sealing flap; the head section being fitted into one or more recesses in the fixing detail. The sealing body may be injection moulded into the fixing detail or be moulded separately by a variety of methods according to the material used. The fixing detail is a sleeve with a "U" or "J" cross-section, and the expense involved in fitting separately a retaining ring, a sealing body and a fixing detail is reduced considerably. The seal can be made in a single operation. Separate stocks of seals are not necessary and the seal cannot be fitted incorrectly.

Title: Charge-coupled device - has parallel section with first charge storage electrode shaped to be wider than succeeding electrodes at least over each channel
IPC: H01L27/105
Filed: 1987-07-21
Abstract: The device comprises a series register having charge storage electrodes for defining charge storage wells and charge transfer electrodes for transporting charge between the charge storage wells. A parallel section has channels extending transversely of the series register, the parallel section having charge storage electrodes spaced apart along the channels. Each charge storage electrode extends transversely over the channels to define a respective charge storage well with each channel to provide a respective row of charge storage wells extending trans -versely of the channels and having charge transfer electrodes for transferring charge between adjacent rows of charge storage wells. A transfer gate transfers charge between the series register and an adjacent row of charge storage wells defined by the channels and a first charge storage electrode of the parallel section. The first charge storage electrode of the parallel section is shaped so that, at least over each channel, the first charge storage electrode is wider than succeeding charge storage electrodes of the parallel section.

Title: Tubular mesh film incorporating ridges of increased thickness - produced having dia. determined by size of annular gas bearing
Inventor: HAVENS CARL B
IPC: B29C55/00
