Abstract: A knife of the kind having a blade (14, 43) and a handle has an extendible and retractable blade edge guard (16, 45). When the blade (14, 43) is extended, any violent movement of the knife with the cutting edge in a leading attitude acts inertially to disengage a detent (27, 55) from a recess (28, 57) in the guard (16, 45) so that a tension spring (17, 46) quickly extends the guard (16, 45) into its projecting, operative position to guard the blade edge (21, 50) and prevent at least serious injury. When the blade carrier (13, 42) is fully retracted, its engagement with a part (31, 58) of the guard (16, 45) causes that also to retract and be engaged again by the detent (27, 55) due to spring-bias.

Abstract: An alpha recoil ion-implantation method uses an alpha-emitting source that is a radioactive parent of the daughter isotope of interest to implant into a suitable substrate the recoil daughter ions resulting from alpha decay of the parent. For example, a ²⁴¹Am source in thin layer form is placed next to a substrate such as a solid state track recorder in a vacuum which houses an assembly for rotating opposing disks receiving the alpha-emitting source and the substrate, respectively. Each alpha decay of ²⁴¹Am results in a ²³⁷Np ion with enough recoil energy to be implanted into the substrate.

Abstract: A wire cut electric discharge machining unit which effects machining by applying a voltage across a work and a wire, and pouring a machining liquid into the gap between the work and the wire. When It is difficult to bring the nozzle sufficiently close to the surface ot the work, the liquid pressure in the nozzle is calculated from the height of the nozzle to vary the standard machining conditions depending upon the liquid pressure in the nozzle to thereby automatically find out optimum machining conditions. Machining conditions (M, t, r) are input from input means (1), and machining conditions (V o , T ono , T offo ) of a standard wire cut electric discharge machining unit are selected from machining condition memory means (3). Liquid pressures (P u , P L ) of the nozzle are calculated by calculation means (2) from the nozzle heights (/ u , / L ) input from the input means (1). Machining condition varying means (4) gives to machining power source (5) the machining conditions (V, T on , Toff) obtained by varying the standard machining conditions from the liquid pressures (P u , P L ) of the nozzle, whereby the practical machining is carried out under the modified machining conditions.

Abstract: Un dispositif de contrôle de fluides corporels comprend sur un substrat (5), (a) une couche de réactif de contrôle (1) contenant un réactif coloré de contrôle qui change de nuance selon le contenu de l'objet à contrôler dans une solution à contrôler, et (b) une couche de nuance de couleur (3) qui sert de référence, qui est colorée par un colorant ou similaire et qui est utilisée pour évaluer la nuance de la couleur présentée par la couche de réactif de contrôle. Les couches (1) et (3) contiennent une poudre absorbant l'eau et absorbent une solution à contrôler. En outre, comme la capacité de la couche de réactif de contrôle d'absorber la solution à contrôler est approximativement égale à celle de la couche colorée de référence, les nuances présentées par la couche de réactif de contrôle et par la couche colorée de référence peuvent être comparées lorsque les deux couches sont humides. On peut ainsi contrôler un fluide corporel avec beaucoup de précision.

Abstract: Dans le tonomètre qui sert à mesurer la tension intra-oculaire de l'oeuil, un jet de fluide est projeté en direction de la cornée, afin de distordre sa surface par la pression du jet. La distorsion de la surface cornéenne est détectée par une modification de la réflexion de la lumière dirigée sur la cornée. Une chambre de volume constant (96) fait partie du système d'émission de fluide, avec une entrée (71) par laquelle le fluide sous pression peut être acheminé dans la chambre lorsqu'un jet de fluide est requis. Un assemblage de lentilles (110, 112) est fixé à l'intérieur de la paroi de la chambre pour permettre que de la lumière soit dirigée en direction de l'oeuil à examiner, un tube (108) s'étendant en outre de façon coaxiale à travers l'assemblage de lentilles de façon à former une saillie vers l'intérieur de la chambre, où il est fermé au niveau de la partie (114), bien qu'il comprenne plusieurs ouvertures (118) ménagées dans la section de parois faisant saillie vers l'intérieur de façon à permettre le passage modulé du fluide depuis la chambre vers l'intérieur du tube.

Abstract: A controller is provided for a baseband switching matrix with one space switching stage. The matrix supplies the controller with a number of service channels (IOTS, CH) of the uplink frames, which channels comprise encoded commands that are decoded by the controller which generates service channels (IOTD, FMC) for the downlink frames and sends them towards the matrix. The controller is subdivided into three functional units: a preprocessing unit (PREL) which decodes uplink frame service channels; a processing unit (ELAB), which receives the commands decoded by the preprocessing unit and/or by a telecontrol station with which it performs a bidirectional dialogue and generates control signals comprising the matrix switching states; an interface unit (INTM) comprising two memories (MEMA, MEMB) alternatively operating as active or backup memory, which store the switching states supplied by the processing unit and send them to the matrix.

Abstract: Retroreflective sheeting has been improved by a coating comprising silica and a transparent polymer selected from aliphatic polyurethanes, polyvinyl chloride copolymers having a minor amount of a comonomer containing at least one carboxylic acid or hydroxyl moiety, and acrylic polymers. Silica comprises 10-80 weight percent (10-70% in the case of polyacrylates) of the transparent protective coating. For example, a solution or dispersion of polyurethane is mixed with a silica sol and possibly other ingredients (e.g. wetting agent, UV light absorber and adhesion promoter), and the composition is coated onto the retroreflective sheet and dried. The coated retroreflective sheeting has superior soil and dew repellancy, retaining a higher percentage of original brightness after exposure to dirt and/or dew conditions.
