Title: Apparatus and method for time multiplexing a resource among a plurality of entities
Inventor: FRASER ALEXANDER G
IPC: G06F9/48
Filed: 1991-02-19
Abstract: Apparatus and methods for time multiplexing a resource among a plurality of entities at average rates and with deterministic delays between accesses to the resource by an entity. An entity accessing the resource received a time slot on the resource; a fixed number of time slots constitute a frame. Each entry receives a fixed allocation of time slots in the frame. When an entity has work for the resource to do, it receives access to the resource for a number of slots in each frame equal to the lesser of the number of slots required to do the work and the number of slots in the allocation. A rate-controlled server is disclosed which defines a frame and allocations therein, as well as a hierarchy of servers which combines rate-controlled traffic with best traffic. In the hierarchy, a rate-controlled server activates a round-robin server when the entitles served by the rate-controlled server do not require all the slots in a frame. A hierarchy of rate-controlled servers is further disclosed which permits access to the resource at widely-differing average rates. In that hierarchy, a number of slots in the frame for a given member of the hierarchy are reserved for the next number down of the hierarchy and the next member down is active only duringthose slots. Further disclosed are nodes of ISDN networks employing ATM which incorporate the servers and hierarchies thereof.

Abstract: Systems (10) for the on-line optical measurement of properties of a translucent moving web (12), such as paper or plastic,  as  it is continually produced,  colored or otherwise converted.   Measured properties include color, reflectance  and  opacity.   A backing  roll  (22)  has  a cylindrical or approximately cylindrical surface (24) which comprises at least one optical standard.   The roll is positioned such that a circumferential portion (26) of the roll surface contacts the back web surface (16) where the web characteristic is to be measured, with the web curving around the circumferential portion.   An optical sensing device (34) is positioned so as to view the front web (14) surface backed by the optical standard or standards.  In several  embodiments,  two sets of reflectance data are collected, one with a "white" optical standard backing and the other with a "black" optical standard backing.   The backing roll surface and the optical sensing device can be arranged such that the sensing device either alternately or simultaneously views portions of the front web surface backed by  each  of  the  optical  standards.    In  other embodiments,  the  backing roll  has  a  uniform  optical standard surface.

Abstract: A B S T R A C T     The knee orthesis appliance is made of carbon-fibre composite material with an integral Menshik linkover four bar chain (21) made of titanium.  It provides the knee joint with secure and reliable support.  Owing to its low weight, it is extremely comfortable to wear.  The angle of bend (22) can be adjusted to suit the individual as prescribed by the doctor.  The shells of the appliance are made from a positive plaster cast (1), using vacuum composite production techniques.  This simple process enables the appliance to be manufactured to a high standard of quality in orthopaedic workshops.  The joint plates (5,6) are inserted between the individual layers of the composite.  Following filling and curing, the sidepieces (16,17) only have to be riveted to the joint plates to complete  the four bar chains and hence the finished appliance.     (Fig. 1)

Title: Magazine for tools and/or workpieces
Inventor: OBRIST BASIL
IPC: B23Q3/157
Filed: 1992-06-01
Abstract: The magazine, having a fixed place in a manufacturing plant, is intended to cooperate with at least one machining device and with a handling device associated with said machining device in order to automatically exchange tools and/ or workpieces on said machining device. The magazine comprises a rotating rack having a plurality of storing planes mounted upon another on a support for bearing the objects to be handled.      Said rotating rack is designed as a separate constructional unit which is exchangeably inserted in a stationary part of the magazine, which stationary part comprises means for rotating said rotating rack. In this manner, the space needed by the auxiliary devices in the magazine station as well as the moving space of the handling device is considerably reduced, due to the fact that even in a prolonged operation of the manufacturing plant one sole magazine is sufficient, and that thus, for the exchange of the objects to be handled, the action of any grip means is limited to this sole magazine.
