Abstract: A cold-working tool for thrusting an attached mandrel (14) partially through a hole in a metal workpiece and extracting the mandrel from the hole is disclosed. The tool comprises a pneumatic riveting gun (12) that has a body (21), a handle portion (22), and an elongate barrel (24). A boss (30) is slidably retained within the outer end of the barrel. The mandrel is attached to the outermost end of the boss. The mandrel has an enlarged diameter portion (38). The riveting gun is connected to a source of pressurized air so that the impulsive forces generated by the riveting gun are transmitted through the boss to the mandrel for thrusting the mandrel through the hole. The tool also includes a housing (56) that substantially encloses the body and barrel of the gun, the housing has a forward end and a rearward end. A nose cap (72) is attached to the forward end of the housing to substantially enclose the boss with the mandrel projecting through a hole in the nose cap. A piston and cylinder assembly (18) is attached to the rearward end of the housing. The piston and cylinder assembly includes a piston (68) and protruding piston rod (70) having an outermost end attached to the body of the gun. The mandrel is extracted from the hole by positioning the housing and attached nose cap between the cylinder (62) of the piston and cylinder assembly and the metal member and then introducing pressurized fluid into the cylinder so that the piston will forcibly pull the gun away from the metal workpiece to extract the attached mandrel therefrom. The tool also includes an operating system that causes the tool to alternately thrust the mandrel through the hole and extract it therefrom.

Abstract: A parts feeding apparatus of the piezoelectric drive type consists of a base (20), a plurality of bimorph cell assemblies (22) each including a leaf spring (23) the lower end of which is fixed to the base (20) and two piezoelectric elements (24) each fixed on respective sides of each leaf spring (23) to vibrate each leaf spring (23) when AC voltage is applied to the piezoelectric elements (24), and a conveyor (26) connected with the upper end of each connecting member (30). Furthermore, the upper end of each bimorph cell assembly (22) is connected with the lower end of each connecting member (30) so that the vibration of each bimorph cell assembly (22) is transmitted to the conveyor (26) to feed articles placed on it. Each connecting member (30) has lower bending stiffness than each leaf spring (23) by forming one or more semicircular cut-out portions 130a) in it or selecting its thickness or its material so that an external force acting on each piezoelectric element (24) in vibration is decreased.

Abstract: A fiber optic coupler (20) is formed by heating juxtaposed optically flat surfaces (34,36) formed on two lengths of optical fiber (22,24) to the glass transition temperature. The fibers bond together while preserving the molecular composition of the fibers at bonded region. Depending upon the depth to which the fibers are lapped to form the optically flat surfaces, the coupler may be either an evanescent field coupler or a core intercept coupler. The fibers may be mounted on curved substrates and then lapped to form the optically flat surfaces. The optical throughput of a fiber may be monitored during assembly of a coupler to permit adjustment of the positions of the optically flat surfaces to produce a desired coupling efficiency. The fibers may then be bonded together by application of energy from a suitable coherent light source such as a CO₂ laser.

Abstract: The invention relates to the production of three dimensional images for direct viewing or for recording on a sensitised recording surface. Hitherto, three dimensional images have been produced by a two-stage process, and the resultant images have needed to be viewed using special equipment. To produce such images in e.g. photography, either a multiple lens camera has been needed, or a means to allow a single lens camera with a slit plate, to move along a horizontal track. The images so produced exhibit a high degree of so-called flipping. More recently, an attempt to overcome these problems proposed the use of a wide aperture lens behind a slit plate. This allows the object to be viewed from various and continuous directions but the image is a spatial image that is inverted in depth, and the process remains as a two-stage process. The object of the present invention is to provide a method and apparatus for the direct production of integral parallax orthoscopic panoramagramic images, which objective is met   by a process comprising directing at an object a means of gathering and focussing incoming radiation from the object of a wavelength to which said means is suited, positioning to either side of said gathering and focussing means a grouping means for producing a number of groups of individual waves, each group emanating from a part of said object, said grouping means generating an image in pseudoscopic form, and a means of encoding the pseudoscopic image as discrete parallactic information on a single plane, for subsequent viewing as an orthoscopic image.

Abstract: The hydraulic brake booster (12) includes a resilient member (96) disposed between an input member (94, 194, 294) and a pair of valve members (98, 101; 112) which control fluid pressure flow from an accumulator (14). When the input member (94, 194, 294) is actuated by the vehicle operator, the resilient member (96) is compressed so that the input member (94, 194, 294) moves relative to the valve members (98, 101; 112) and thus provides for greater movement of the input member (94, 194, 294) than for the valve members (98, 101; 112). The booster (12) includes a hydraulic or mechanical lockout which, in the absence of fluid pressure from the accumu­lator (14), eliminates the movement of the input member (94, 194, 294) relative to the valve members (98, 101; 112) so that the relative movement eliminated is not added to the valve stroke during manual operation of the booster (12).

Abstract: The invention relates to a device for processing tissue parts 7, especially of an animal and/or vegetable nature, to form roastings, granulate, etc. by comminution and/or mixing by means of a cutting mixer with a rotating bowl 1 for receiving the tissue parts 7 and with rotating knives 3. To eliminate the frictional heat occurring during comminution, it is proposed, according to the invention, to mount a spray nozzle 6 for low-temperature liquefied gas outside the tissue parts in front of the knives 3 penetrating into the tissue parts 7, in the direction of rotation 5 of the bowl 1. The spray nozzle 6 is directed at a point of the tissue parts contained in the bowl located immediately in front of the knives penetrating into the tissue parts 7, in the direction of rotation 5 of the bowl 1. Sprayed liquefied gas is therefore introduced immediately by the knives penetrating into the tissue parts 7. Tissue parts 7 are prevented from freezing hard on the spray nozzle 6. <IMAGE>

Abstract: Electronic locking system including keys (30) and self-sufficient door locking units (50) both of which carry multiple "zone" codes (F1,F2...). Upon recognition of a key (30) by a door unit (50), the zone codes within the key and door unit are matched against each other so that a match between any one of the key zone codes (FI) and any one of the door unit zone codes (FJ) will result in an "allow access" decision (366). In the "basic zone" function (350), this decision will permit unlocking of the door (368); in other keying system functions or features (330), additional steps may be required for such unlocking, and the coding of either the key or door unit may be altered (340). The keying system architecture, and method of issuing keys, may be defined in terms of a directed acyclic "door group" graph (400) or equivalent data structure, door groups (401,402...) being defined hierarchically as door units, groups of door units, or groups of door groups. Each node of this graph (400) is identified with a given door group and, except for terminal modes (404,405,415,417,422-429) (which are typically identified with given door units), each such node has an associated "choice rule" (450). In issuing keys (30) the key issuing operator, working from a given door group (401) as the starting point, traverses subordinate nodes (402,403...) subject to limitations and decisions imposed by the choice rules (450), until only terminal nodes (404,405....) remain -- thereby defining the coding of a particular key.
