摘要:
Es wird ein Verfahren zum Herstellen eines akustischen Widerstandes vorgesehen. Eine Mehrzahl von ersten Löchern (10) wird in einem Basismaterial (100) mit einer ersten und zweiten Ausdehnung (100a, 100b) erzeugt, um ein Lochmuster zu erzeugen. Eine Lochgröße und/oder ein Lochabstand ist entlang der ersten und/oder zweiten Ausdehnung (100a, 100b) ungleichmäßig verteilt ausgestaltet.

O elemento resistivo estampado (1) é produzido a partir de um processo de estampagem e é destinado a ser utilizado em substituição das resistências elétricas helicoidais convencionais, seja em secadores de cabelos e equipamentos congéneres, seja em outros tipos de equipamentos de aquecimento, o elemento resistivo estampado (1) é produzido como um blank a partir de uma chapa metálica que apresenta coeficiente resistivo conhecido.
摘要:
Apparatus and method for forming a helical flight segment A carriage (40) is mounted side-by-side with a stationary support (30) and, in use, the carriage (40) is movable substantially parallel to the support (30) with a substantially flat sliding surface of the carriage (40) moving across a substantially flat support surface (31) of the support (30). Both the stationary support (30) and the movable carriage (40) have respective clamping means (50) for holding respective edge margins (24, 25) of a radial slot of a flat circular disc (20), having a central bore, which is to be shaped into a helical flight segment (120). The edge margin (24) clamped in the movable carriage (40) is displaced relative to the edge margin (25) clamped in the stationary support (30) upon movement of the carriage (40) relative to and parallel to the substantially flat support surface (31), thereby deforming the disc (20) to a single pitch helical form. In other versions, the stationary support may be replaced by a second movable carriage, the respective carriages then being relatively movable along close parallel paths. These carriages are slidably mounted on a stationary support which may be a base or a frame.

A method for assembling a syringe includes supporting a syringe barrel having a stopper being movably disposed therein. A distal end of a plunger rod is inserted into the compartment of the syringe barrel. An initial digital image is taken of the stopper within the syringe barrel. The distal end of the plunger rod is coupled to the stopper located within the syringe barrel so that the plunger rod is secured to the stopper. A plurality of further digital images of the stopper within the syringe barrel are taken during or after coupling the distal end of the plunger rod to the stopper. Information determined from each of the further digital images is compared to information determined from the initial digital image using a computer processor to determine if the stopper in each of the further digital images has moved relative to the syringe barrel.
摘要:
An electrolytic cathode assembly includes an electrically conductive hanger bar, a deposition plate attached along an upper end to the hanger bar to define a joint, and a protective covering generally surrounding the hanger bar and a portion of an upper end of the deposition plate so as to substantially enclose the joint. The protective covering may be die formed from bending a sheet of material. A corrosion resistant material is injected into a channel between the protective covering and the hanger bar to form a substantially continuous seal extending around the hanger bar, thereby to at least hinder fluid flow into the protective covering.
