Title: Snap system comprising mating rivet
Inventor: James D Martell
IPC: F16B5/04
Filed: 2021-11-04
Abstract: The present disclosure is related to a snap system including a mating component and a snap component that connect by means of a snap fit or otherwise. The mating component simplifies the assembly process by combining a structural component and an attachment point. The snap component is associated with a removable component that mates with the attachment point of the mating component. The snap system includes a mating component that combines a structural component to secure a material and an attachment point to secure a snap component. The design of the structural component allows the mating component to be used with a variety of materials having a variable thickness. The mating component is a versatile feature as the structural component self-adjusts to the thickness of the material provided. The snap system decreases the amount of components necessary for manufacturing, which may decrease the cost, as well as improve the visual appeal.

Title: Vacuum cleaner
Inventor: ANTHONY ANDREW BUCHANAN HARKER
IPC: A47L5/24
Filed: 2023-06-29
Abstract: A vacuum cleaner comprises a dirt separator (100, fig 2), an airflow inlet (134, fig 6) into the dirt separator, and an suction motor (500, fig 71) for causing generation of an airflow through the airflow inlet. The suction motor comprises a mixed flow impeller (504, fig 47), and wherein the suction motor is configured so that, in use, the airflow is drawn into the suction motor in a direction towards the dirt separator and the airflow is discharged from the suction motor in a direction away from the dirt separator. The suction motor comprises a diffuser 520, 522 located downstream of the mixed flow impeller and wherein, in use, a direction of the airflow downstream of the diffuser is at least 180 degrees from a direction of the airflow as the airflow passes through the suction motor.

Filed: 1988-06-13
Abstract: Η εφεύρεση αναφέρεται σε ακίδα (21) για σύνδεση ενός ηλεκτρικού αγωγού (2) με PCB (4). Η ακίδα έχει ένα πρώτο τμήμα (24) που διεισδύει εντός οπής εντός του PCB και ένα δεύτερο τμήμα (26), στο οποίο συνδέεται ο ηλεκτρικός αγωγός (2) δι' ολισθαινούσης επαφής (8). Η εν διατομή διάσταση (d2) του δευτέρου τμήματος (26) είναι μεγαλύτερη από την εν διατομή διάσταση (d1) του πρώτου τμήματος (24), και μεταξύ αυτών των τμημάτων η ακίδα (21) έχει κύρτωμα (27) με οξείες ακμές. Η οπή εντός του πίνακα κυκλώματος επιστρώνεται με μέταλλο το οποίο συνδέεται μέσω των γλωττίδων (22) με ηλεκτρικούς αγωγούς (3) του PCB (4). Η ακίδα (21) συγκολλείται εντός της οπής με την βοήθεια συγκολλητικού μετάλλου (25) και συλλιπάσματος. 'Οταν το συλλίπασμα θερμανθεί διολισθαίνει κατά μήκος της επιφανείας της ακίδας. Κατά την διάρκεια της συγκόλλησης, το κύρτωμα (27) με τις ακμές προλαμβάνει το συλλίπασμα από το να φθάσει το δεύτερο τμήμα (26) της ακίδας (21), όπου το δεύτερο τμήμα έχει επιφάνειες επαφής (29) επί της ακίδας (21) έναντι της ολισθαινούσης επαφής (8) και όπου το συλλίπασμα θα είναι μια αντίσταση επαφής. Η ακίδα (21) έχει το πλεονέκτημα ότι το πρώτο τμήμα της (24) είναι περιορισμένο και ότι οι γλωττίδες (22) μπορούν να έχουν μικρή εξωτερική διάμετρο. 'Ετσι δημιουργείται εδώ χώρος για μεγάλο αριθμό αγωγών (3) μεταξύ δύο γειτονικών ακίδων (21).ω

The novel chiral aryloxypropionates of the general formula  <IMAGE>  are two-fold chiral and in which the symbols have the following meaning: R1 denotes a straight-chain alkyl or alkoxy radical having 1 to 16 carbon atoms or a branched alkyl or alkoxy radical having 4 to 16 carbon atoms, it being possible for one or two non-adjacent CH2 groups to be replaced by a sulfur and/or oxygen atom; A denotes one, two or three aromatic or heteroaromatic rings which are linked to one another directly or via one or two COO groups; B denotes a chemical bond or one or two aromatic or heteroaromatic rings which are linked directly to one another; R2 (a) if B is a chemical bond, denotes an alkyl radical having 2 to 10 carbon atoms which contains an asymmetrical carbon atom which is substituted by CH3, halogen or a COOC2H5 group, or an alkyl radical having 3 to 10 carbon atoms which contains two adjacent, asymmetrical carbon atoms of which one is substituted by halogen and the other by a CH3 group, or which, together with an O, form an oxirane ring, or (b) if B denotes one or two aromatic or heteroaromatic rings which are bonded directly to one another, denotes alkoxy radicals having the same number of carbon atoms and the same structure of the alkyl group as under (a).

Abstract: Thermally decomposable Group IIIa compounds are purified by conveying the relatively impure material through a prescrubber module, then heating the scrubbed Group IIIa compound and conveying same through a preconditioned gas chromatographic column packed with a porous polymeric material. After isolation, the purified material is cooled, demisted amd collected. Thermally decomposable Group Va compounds are purified by conveying the heated relatively impure material through a preconditioned gas chromatographic column packed with a porous polymeric material. After isolation, the purified material is cooled and collected. Epitaxial semiconductor films of purified thermally decomposable Group IIIa and Group Va compounds with added dopant are prepared by diluting the film components with inert carrier gas to predetermined concentration levels, thoroughly mixing the components, then depositing a crystal layer prepared from the mixed components onto a substrate by thermally decomposing the mixed components in a reactor.
