Abstract: A tracking mirror device, in particular for a video disc player, in which for following an information track on a video disc with a beam of radiation, use is made of a mirror which oscillates at a high frequency, which causes the beam of radiation, which serves for scanning the information track, to oscillate transversely to the information track at a high frequency and a small amplitude, while the filtered out high-frequency signal, as a function of its amplitude and its phase relationship with the high frequency voltage which is applied to the oscillating mirror, yields a control signal for following the information track. In accordance with the invention, use is made of an oscillating mirror which is driven electromagnetically and which is connected to oscillation compensation elements by means of springs which elements oscillate in phase opposition to the mirror. Thus, an oscillator mirror is obtained which can readily be excited to natural resonance and thus requires little power. On the mirror a piezo-electric miniature acceleration transducer can be mounted, which can provide a feedback signal so that the oscillating mirror can be included in a self-oscillating circuit.

Abstract: A method of making a disc having integral blades wherein (1) a billet is preformed with the disc being formed close to final shape except that material needed to complete the outer portion including the blades is placed adjacent the outer edge of the preform; (2) the preform dies are changed and the preform is pressed into its final form. The outer die is formed as a two part die having an inner section and outer section, said outer section placing a holding force on the inner formed section and a forming force on the material needed to complete the disc and blades. The blade dies are formed to have a blade cavity longer than the length of the blade desired so that the ends of the blades can be machined to a desired length.

Abstract: A process for recording laser radiation is disclosed. A photosensitive material comprising a copying coating and a carrier is exposed to visible laser light having no ultra-violet component and is then developed. The process is characterised by the use of a negative working diazonium compound and a binder which together form the copying coating. The diazonium compound comprises more than 25 percent of the total coating weight. The relatively high concentration of diazonium compounds causes an increased photosensitivity when the material is exposed to laser light from which virtually all the ultra-violet in the range of sensitivity of the diazonium compound has boon excluded loading to increased exposure speeds or of shortened exposure times.

Abstract: Improved machine and method for longitudinal compressive treatment of webs employing a two roll drive nip. Specially arranged initial parts of one or a pair of stationary retarding members are positioned at the exit side of the drive nip in the region of minor divergence of the roll surfaces to provide damming forces. The initial part of the retarding member, preferably a curved, resilient nipping element, is shaped to oppose the flow of the web. By its construction and position close to the line of centers of the rolls, it establishes a very compacted column extending upstream to an initial treatment point continually located in the drive nip, between the moving surfaces of the rolls. In this region, longitudinal compressive action occurs upon the web in a continuous and uniform manner, preferably with compensatory action in response to variations in the forces exerted by the compacted column of web. This compensatory action is provided by resilient deformation of a retarding member in the direction normal to the plane of the web, resilient adjustment movement of a retarding member in the direction away from the nip roll center line, and in some cases, by resilient response of the compacted material itself. The retarding members may accomplish their resilient movement by swinging about the roll axes and by moving longitudinally of the web flow path. The retarding member, or the leading member of a pair, preferably, in the start-up position, has its initial part located upstream of the running position.

Abstract: An apparatus for selecting an elevator cabin at a transportation installation, especially an elevator system, for direct travel of an elevator group, controlled by means of a group control, possesses additional storey call transmitters and storey call storages. The storey call storages are connected with a call blocking device having infed thereto a first signal train or sequence produced during scanning of the storey call storages. The call blocking device possesses further inputs, to which there is infed information blocking already allocated calls, so that at its output there appears a second signal train or sequence no longer containing the allocated calls. This output is connected with a respective input of call allocation devices operatively associated with the elevators. The call allocation devices are operatively interconnected with one another by means of a switching circuit. Upon the occurrence of a coincidence signal of an elevator which is ready to service a storey call, the related call allocation device is prepared for the call allocation. Upon subsequent occurrence of a storey call there appears at the output of the call allocation device a control signal which triggers the direct travel.

Abstract: A process for the preparation of penicillanic acid 1,1-dioxide and esters thereof readily hydrolyzable in vivo. Said process involves dehalogenation of a 6-halo or 6,6-dihalo derivative of penicillanic acid 1,1-dioxide or ester thereof readily hydrolyzable in vivo or a carboxy protected derivative thereof (e.g. by hydrogenolysis). The 6-halo and 6,6-dihalo derivatives of penicillanic acid 1,1-dioxides, esters thereof readily hydrolyzable in vivo, and carboxy protected derivatives thereof are novel intermediates. Penicillanic acid 1,1-dioxide, and esters thereof readily hydrolyzable in vivo, are known compounds which are useful as beta- lactamase inhibitors and for enhancing the effectiveness of certain beta-lactam antibiotics (e.g. the penicillins) in the treatment of bacterial infections in mammals, particularly humans.

Abstract: A regenerative liquid propellant gun having structure which reacts to combustion pressure to dispense and regulate the flow of liquid propellant from an included reservoir as one parameter for obtaining a predetermined pressure/time curve of gun chamber pressure. A first coaxial pumping piston is a differential area pressure piston operating between the combustion chamber and the primary propellant reservoir. A second coaxial piston in a bore in the first piston opens and closes injection ducts running through the pumping piston from the primary reservoir to the bore to interdict flow of propellant to the combustion chamber as a result of relative motion of the two pistons as one or both move responsive to propellant combustion pressure. The second piston may also be a differential area piston operating between the combustion chamber and a second reservoir which may also dispense propellant to the combustion chamber or may be a part of a separate hydraulic system dedicated to hydraulic control of the second piston. The disclosure includes several alternative arrangements for control of the relative movement between the pistons.
