Title: Cracking catalyst
IPC: C10G11/02
Filed: 1978-04-25
Abstract: The deactivating effect of metal contaminants (Ni, Fe and/or V) on clay-based cracking catalsyts is counteracted by contacting the catalyst at high temp. with a passivator comprising Sb selenide, Sb sulphide, Sb sulphate, Bi selenide, Bi sulphide and/or Bi phosphate. Pref. passivators are Sb2Se3, Sb2S3, Sb2(SO4)3 and Bi-PO4. The amt. used is pref. sufficient to deposit 0.05-5 wt.% of Sb or Bi on the catalyst. The treatment is pref. effected by contacting the deactivated catalyst with the finely divided (-150 mesh) passivator at 427-816 degrees C in a reducing atmos. (pref. in the presence of H2). The passivator can be added to the circulating catalyst in the cracking unit or to the cracking feed. The treatment increases the activity of the catalyst, increases the gasoline yield and reduces coke and/or H2 prodn. during cracking.
Patent ES-469899-A1 (ES)
Title: Starch acrylamides and the method for preparing the same
IPC: C08F299/00
Filed: 1978-05-16
Abstract: The invention relates to starch acrylamides containing polymerizable pendant acrylamide groups. The hydrophilic or hydrophobic properties of the starch can be altered or modified by the acrylamide groups or the type of starch chain. The starch acrylamides can be homopolymerized or copolymerized with other ethylenically unsaturated monomers as well as other cross-linking reagents to provide water-resistant, clear, flexible coatings or shaped articles. The hydrophilic starch acrylamide hydrolyzates herein readily disperse into water at a high solids level to provide low-viscosity pastes which may be used as a vehicle to prepare flexible, water-insoluble starch-based coatings. The starch acrylamides may be prepared by etherifying a starch with N-methylol acrylamides in the presence of an acid catalyst and a polymerization inhibitor.

Patent ES-8103288-A1 (ES)
Title: A fluid pump for location within a liquid reservoir.
IPC: F04B43/10
Filed: 1980-05-02
Abstract: A fluid pump for location within a reservoir and which is operable with rise and fall of liquid within the reservoir. The pump comprises a tube of a resiliently deformable material, an abutment surface which is engaged by the tube and a float device which is mounted to the tube. Liquid entering the reservoir causes upward movement of the float device and such movement of the float device causes increasing engagement between the tube and the abutment surface. The increasing engagement between the tube and the abutment surface causes the tube to deform resiliently and a localized reduction in the contained volume of the tube is thereby effected to cause expulsion of fluid from the tube. Conversely, as the liquid level falls in the reservoir, the float device moves downwardly to reduce the extent of engagement between the tube and the abutment surface, so that the tube tends to resume its initial contained volume.
Patent ES-8200800-A1 (ES)
Title: A control for a single phase AC motor.
IPC: H02P1/42
Filed: 1980-09-16
Abstract: This disclosure relates to control apparatus and particularly to a triggered switch connected in a first or controlled circuit and a trigger device connected in a second circuit. AC currents flow through the first and second circuits and there is a changing phase angle between the currents. Further, the current level in the second circuit changes. When the phase angle is greater than a certain value and the current level in the second circuit is above a certain level, the trigger device triggers the switch and energizes the first circuit. At angles below the value and current levels below the certain level, the switch is not triggered. Thus, the changing phase angle may be utilized to control the first circuit. The triggered switch is a thyristor type of device such as a triac, and the trigger device is preferably a reed switch. The control apparatus is particularly useful in controlling the start winding of a single phase AC motor.

Title: Self-pressurizing dispensing container.
IPC: B65D83/58
Filed: 1981-12-10
Abstract: A flexible enclosed plastic bag disposable in a product container for supplying dispensing pressure therein. The bag cofltains an envelope having its outer sides permanently attached to the respective inside walls of the bag. One of the sides of the envelope has one of a two component gas generating system disposed in a plurality of aligned pocket members formed therein with their openings facing the other side of the envelope, the latter being releasably adhered to the first mentioned side to enclose said one component in said pockets. The bag contains the second component and a starting means to initially generate gas and expand the bag and develop product dispensing pressure within the container.

Filed: 1981-12-18
Abstract: A hydraulic brake booster (10) includes a spring-balanced control valve (42) communicating pressurized fluid to a pressure chamber (14) in response to an operator input. The magnitude of the fluid pressure communicated to the pressure chamber (14) is a function of the balance of spring forces applied to the control valve (42) by a pair of opposed springs (50, 82). An adjustable assembly (92) engages one of the opposed springs (50, 82) so that the balance of spring forces applied to the control valve (42) may be adjusted to limit to a safe level the maximum fluid pressure communicable to the pressure chamber (14). The adjustable assembly (92) includes a pair of relatively-rotatable members (106, 108) which each define oblique cam surfaces (122, 124) engaging the other member.
