Title: Method of coating a hydrophobic fibrous material with an amphiphilic polyelectrolyte.
Inventor: FORCE GUNILLA ELSA GILLBERG LA
IPC: D06N3/02
Filed: 1996-08-22
Abstract: A method of coating a hydrophobic fibrous material with an amphiphilic polyelectrolyte which involves coating the hydrophobic fibrous material with a foam under conditions sufficient to substantially uniformly coat the hydrophilic fibrous material with the amphiphilic polyelectrolyte. The foam is generated from a solution of an amphiphilic polyelectrolyte in water. The hydrophobic fibrous material may be a polyolefin, such as polyethylene or polypropylene. The hydrophobic fibrous material also may be a nonwoven web, such as a meltblown or spunbonded nonwoven web. When the hydrophobic fibrous material is a nonwoven web, the web typically is coated with the foam, vacuum extracted, nipped, and dried.

Patent NL-7000431-A (NL)
Title: Production well steam injection lagging
IPC: E21B36/00
Filed: 1970-01-13
Abstract: Steam is injected through a stainless steel string into the formation, to lower the viscosity of the oil and thus promote outward production. At the same time a solution of silicate is piped into the annular space between the string and the perforated hole casing so that the steam in the string heats and boils off the water from this silica solution, a thin even skin of foam forms on the outside of the string, thus conserving the heat and so the efficiency of the injected steam. Centering devices should be used to keep the string out of contact with the hole wall. Silica solution should have density 22-50 Be at 20 degrees C., with ratio between 1.3 : 1 and 1-5.0 : 1 in terms of silica to alkali metal oxide.

Patent NL-7313772-A (NL)
Title: Door lock with decorative housing and actuating handle - has latch actuated by handle via rectangular bar with latch and bolt locked independently
IPC: E05B59/00
Filed: 1973-10-08
Abstract: The lock housing accommodates two separate locking mechanisms and a greater degree of security is achieved on using this lock. If used for hotel rooms the management can have keys for operating the bolting elements of all locks in the hotel. The guest can lock the door so that no one can enter the room. In one version two decorative housings are arranged on each side of the door and the one on the inner side contains a coupling mechanism for both locking mechanisms. This coupling mechanism is operated by the handle so that on rotating the handle one lock is released first and the latch is released later. A square peg connected to the handle is used to actuate a wedge shaped latch. The locking wedge acts on a locking hook by means of a lever. When the door is closed the locking link is pushed inwards and hence the latch is locked. This latch cannot be retracted into the housing if for instance it is tampered with by a tool. The movements are transmitted by a lever.

Title: Direct heating of sulphuric acid soln. - using electric current passed between electrodes immersed in the soln.
IPC: H05B3/60
Filed: 1977-12-16
Abstract: Direct heating of a soln. of H2SO4 is effected using a current passed between electrodes immersed in the soln. The surfaces of the electrodes are subjected to a passivation pre-treatment, so that the resistance of transition between the electrodes and the H2SO4 soln. is at least as high and pref. 3-5 times the resistance produced by the H2SO4 soln. Used e.g. in the distn. of H2SO to increase its concn. or to eliminate dissolved impurities. Process gives a better thermal transfer and thermal yield than prior indirect processes. Owing to the high resistance between the electrodes and the liq. the process also requires a lower current intensity and therefore simpler electrical appts. than previous direct processes.

Title: Isolation of lysozyme useful as food preservative - and for treating inflammations, by adsorption on ion-exchange resin and elution
IPC: C12N9/36
Filed: 1978-07-04
Abstract: Isolation of lysozyme (I) from (I)-contg. material (esp. albumen) is carried out by contacting the material with a weakly acidic COOH-contg. ion-exchange resin after adjusting the resin to a pH of >7.1. or 6 (pref. 8-9.5) and washing it with water. The adsorbed (I) is then eluted from the resin. (I) is used as a food preservative and in the treatment of inflammations and injections. When the prefd. pH of 8-9.5 is employed (cf. pH 6-7 in GB 1110466), the physical and chemical properties of the by-produced (I)-free albumen are unaltered, so it is still useful for nutritional purposes.
