Abstract: A motorless label printer employs a matrix ink jet print head under which a continuous web of labels is moved during printing. An encoder in the path of the web is rotated to generate pulses signifying the position of the labels with respect to a reference that is signalled by detection of an aperture on the web by an electric eye. The printer includes a support for a spool of the web and a delaminator for separating the printed labels from the web substrate.
Abstract: A toy flying discus is fabricated from a form sustaining, resilient, plastic foam material having a density which enables the discus to have an aerodynamic profile and sufficient mass to achieve distant flight with minimal launching force and to have sufficient resilience to absorb impact forces thereby preventing damage to objects which it contacts. The surface of the discus is absorbent to blend applied pigments for achieving an aesthetically pleasing appearance.

Abstract: An apparatus and method for rapidly identifying the chemical compositions and concentrations of solutions and for discriminating among solutions of different chemical compositions and concentrations of the solution is monitored by applying across a predetermined volume of the solution a predetermined voltage for a predetermined time after which the application of voltage is terminated and the voltage time characteristic measured across the solution as the voltage decays is compared with an empirically obtained voltage versus time characteristic for a solution having a standardized composition and/or concentration.
Abstract: A lens and method of fabrication thereof for increasing depth of focus where the lens power can be a constant but the amplitude and phase of the wave across the pupillary aperture are variables. The lens can be constructed by shading regions thereof in accordance with a mathematical function, e.g., a Gaussian distribution or Bessel function over a predetermined geometry, such as e.g., concentric, parallel or radial. The lens may be of single power or multiple power, e.g., of the bi-focal type.
Abstract: A gangway bellows for fastening to the end of a vehicle, the bellows having a clamping cable along its peripheral edge which cooperates with a channel carried by the end of the vehicle for attaching the end of the bellows to the vehicle. A connecting strip of elastic material, such as rubber, extends along the peripheral edge of the bellows and embraces the clamping cable. The connecting strip is located between the clamping cable and the channel on the vehicle and serves to resiliently clamp the cable to retain the latter within the channel.
Abstract: A preferably vertical air separator with a rotating separator wheel upon which separating air loaded with fine goods flowing from outside towards the inside impinges, from which said separating air axially flows off through an outlet connection pipe in order to be guided to its further use, e.g. in a filter or the like, said separating wheel being provided with a downstream cover plate and a second cover plate being axially distanced therefrom, and blades being disposed between the two cover pates at their periphery, and the outlet connection delivery end averted from the separating wheel emptying into an outlet chamber the cross section of which is distinctly larger than the cross section of the said outlet connection pipe, so that there occurs an abrupt change of the cross section between the outlet connection pipe and the said outlet chamber.
Abstract: An airless hand held hydraulic pump unaffected by gravity continuously maintains pressure on the fluid in a dynamic reservoir chamber to enable pumping into a dynamic pressure chamber for actuating a forcing rod irrespective of the orientation of the pump. A release valve permits fluid return from the pressure chamber into the reservoir chamber. The pump can be fitted with a tool such as a door forcer.
Abstract: A system and method for applying a disinfectant solution which may include a salt and a buffer to an instrument, object or mass wherein the solution is selectively rendered disinfecting and neutral by impressing a voltage across it to ionize an unstable salt which yields toxic ions only while the voltage is applied. The system can be used to disinfect both metallic and plastic instruments.
Abstract: The nozzle ring associated with the propeller and rotatable together with it around the vertical axis is designed as a partially open annulus and arranged such that the inner circle of the nozzle--and consequently practically the wing tip circle as well--approximately touches the respective local separating surface between the flow and the floating body or boat.

Abstract: An energy-generating plant including a solar generator, having solar cells, for producing electrical energy. The electrical energy is supplied to a direct current converter, the output power of which may be used to charge an energy storage system, such as batteries. The input resistance of the direct current converter is adapted, such as by a microcomputer, to the maximum power point (MPP) of the solar generator, the MPP being dependent upon the solar insolation and the temperature of the solar cells. At start up of the plant, or when there is a change of power at the output of the direct current converter, a search process is carried out to attain the MPP of the solar generator. The energy storage system may be used to energize an electric motor for driving the propeller of a ship.
