Title: Electronic switching device, preferably operating without making contact
Inventor: BUCK ROBERT ING GRAD
IPC: H03K17/94
Filed: 1983-04-07
Granted: 1985-10-10
Abstract: A contactless motion detector is energized from a source of current via a pair of supply leads and delivers an output signal by way of a further lead through an Exclusive-OR gate to a control electrode of a binary electronic switch in circuit with the source and a load to modify the flow of load current upon the approach of a metallic element, for example. The Exclusive-OR gate, having one input connected to that further lead, has another input connected to an ancillary lead which in turn is connected to the other supply lead through a decoupling diode. A selector switch enables completion of the load circuit directly via the latter supply lead, thereby causing inverted transmission of the output signal of the detector to the control electrode, or by way of the ancillary lead to prevent the inversion of that output signal, whereby the load current can be either increased or reduced upon the occurrence of the event to be detected.

Title: Method of manufacturing synthetic resin pen nibs
Inventor: KURIHARA NORIGI
IPC: B29K67/00
Filed: 1984-06-27
Granted: 1988-11-24
Abstract: Method of manufacturing synthetic resin pen nibs is disclosed, which pen nibs may suitably be employed in writing instruments for fine lettering or drawing fine lines. The pen nibs are formed of thermoplastic crystalline synthetic resin, e.g. polyethylene terephthalate resin, which is extruded from a molding die and subjected to rapid cooling to form a continuous rod in amorphous state. The rod is axially stretched under predetermined temperature condition to achieve oriented crystallization of the resin molecules, and is further heat-treated such that non-oriented fine crystals are dispersed and grown between oriented crystals and remaining amorphous regions. Pen nib thus obtained has highly improved physical and chemical properties.

IPC: B66F9/075

Granted: 1990-03-08
Abstract: The industrial truck or vehicle comprises a support body or member supporting an elevatable platform. The support body is supported and guided on both ends by a respective transverse pivot joint of a respective driving module or unit. The width of the support body and the platform is narrower than the width of the two driving units. This narrowing or reduction in width of the industrial vehicle ensures that the complete platform region on both longitudinal sides of the industrial vehicle is manually accessible despite providing good lateral vehicle stability. Furthermore, the torsional elasticity of the support body is increased such that the support body in combination with the transverse pivot joints provide sufficient travel surface adhesion or floor traction of all drive wheels and support or free-running wheels even over irregular or uneven travel surfaces. The industrial vehicle possesses an emergency recovery device so that it can be temporarily driven without auxiliary devices if up to two wheels become blocked. For this purpose the driving units are tilted individually or in combination about the still functional wheels by means of a respective drive spindle until the blocked wheels are free of the floor or ground surface and the industrial vehicle is rendered mobile. The reduction in width of the industrial vehicle and the autonomous capability of recovering from emergencies permits this industrial vehicle to be utilized in flexibly-organized assembly plants, especially in the automotive industry.

Abstract: A monitoring device for use with a loop circuit including a plurality of lights, which includes a monitoring current transformer having a magnetic core with a primary circuit connected in series with the loop and a secondary circuit coupled to the primary circuit, the primary circuit being arranged such that the loop current saturates the transformer core and the secondary circuit being in open-circuit condition, the monitoring current transformer generating a monitoring voltage signal in response to each inversion of the loop current. The monitoring voltage signal is used to generate a window signal during the time interval when the monitoring voltage signal has a significant value and the window signal is then used to control the integration of a signal representative of the loop voltage with a view to producing a detecting signal which is indicative of the number of defective lights. The integration time interval is thereby determined whatever the loop current waveform may be.

Abstract: A method for obtaining an actual linear standard curve in a sandwich type of immunoassay where a first antibody bound to an insoluble support and a second unbound labelled antibody complex with the antigen contained in a test sample to form an insoluble antibody:antigen:labelled antibody complex which is then detected. Unbound unlabelled first antibody and/or unbound unlabelled second antibody are added to the reaction mixture to divert excess antigen away from the desired end-product complex, thus rendering the antigen of interest the rate-limiting factor in the overall immunoreaction. This results in a pseudo first-order reaction which produces an actual linear standard curve.
