Inventor: SHEEHY DAVID B
IPC: H04L12/46
Filed: 1989-09-01
Abstract: A method for handling data frames (71,81) by a bridge (51) between a first network (61) which does not require route information within data frames (71,81) and a second network (21,22,23,24,25) requiring route information (74) within data frames (71,81) is presented. A system memory (12) includes an address table (14,140,141). In the address table (14,140,141) are a plurality of entries. Each entry is for a single station (31-60) on the first network (61) or the second network (21,22,23,24,25). Each entry contains a first field (17,170,171) which is the address of the station (31-60) and when the station (31-60) is in the second network (21,22,23,24,25) the entry additionally includes a second field (19,191) which contains a route to the station (31-60). When a first data frame (81) having a first destination address (72) is received from the first network (61), the address table (14,140,141) is checked for an entry which has the first destination address (81) in the first field (17,170,171). If an entry is found indicating that the first destination address (81) is for a station (31-54) in the second network (21,22,23,24,25), the route information (74) in the second field (19,191) is added to the first data frame (81) to create a first modified data frame and the first modified data frame is sent out on the second network (21,22,23,24,25). If no entry is found for the first destination address (81) a route discovery process is initiated to discover a route to the station (31-54) on the second network (21,22,23,24,25) with the first destination address (81).

Abstract: A drum-like rotor having numerous, closely spaced, elongated rows forms of permanent magnets arranged end-to-end and secured to the outer surface of the rotor, produces a high-density, rapidly reversing magnetic field in a band-like zone which is spaced a short distance from,and extends along the length of,the rotor outer surface. The magnetic field induces eddy currents in pieces of different metals passed through the zone which produces repulsive magnetic forces of different intensities in different metal pieces, and thus, magnetically separates such pieces. The rows of magnets, in their radial direction, are alternatingly thicker and thinner,so that the outer surface of the thinner rows are depressed relative to their adjacent thicker rows. The outer surface of the magnets of each thicker row have a polarity which is opposite to the polarity of their next adjacent thicker row magnets, and the direction of the magnetic polarity of the magnets of the thicker rows are radial relative to the rotor. The side edges of the magnets of the thinner rows have the same polarity as the polarity of the outer surfaces of their adjacent thicker row magnets. The directions of the magnetic polarity of the thinner row magnets are generally circumferential, relative to the rotor. Thus, magnetic flux flows transversely through each of the thinner row magnets and then radially outwardly through their adjacent thicker row magnets, returning over the exposed surfaces of the thinner row magnets to the next adjacent row of thicker magnets and, therefore, radially inwardly of the rotor and transversely of the thinner row. Thus, the direction of the magnetic flux flow through the zone changes as the successive thicker and thinner rows pass alongside of the zone as the rotor rotates.

Abstract: A burner automat is disclosed, the faulty position of which, caused for example by the failure of the flame after setting in operation, can be cleared on the one hand by a reset button (10) arranged on the burner automat and on the other hand in a remote-operated manner by means of a reset pulse generator (13). By means of a pulse, which is triggered by a momentary-contact switch (19) and acts on the flame relay (1), the flame relay (1) is briefly excited, the fault contact (7) being returned from its faulty position to the normal position by an actuation segment (11) coupled to a slide (2) for actuation of a contact set (3). Such a burner automat can advantageously be used in compact heating devices, in which the reset button (10) is not easily accessible. <IMAGE>

Abstract: A bit addressing system is disclosed in which on N-bit long addressing for the main storage is executed by means of a computation including a plurality of fields in an addressing operand. When there exist predetermined fields in the addressing operand, the value determined by the fields is regarded as the value for the bit unit in the two's complement representation, and a base address and a bit offset are generated by adding the value obtained by shifting the bit unit value by M bits in the direction of the lower order bits, to the address of the byte unit. Namely, it becomes possible to designate two effective addresses of a base address which is a byte address and a bit offset which is the bit displacement from the base address by means of a single operand. The range of designation of the bit offset is from -2 N-1  bit to (+2 N-1 -1) bit, and it is possible to designate the range of 2 N+M  bits as bit addresses.

Abstract: A sterilizing crusher includes a hot-air sterilizer (5, 12, 19) disposed upstream of a power-driven crushing unit (30, 31). The hot-air sterilizer is kept at a tempera­ture in the range from 160°C to 200°C for a predetermined period of time so that medical waste such as used medical treatment aids is completely sterilized before it is fed to the crushing unit. Since the sterilization is accomplished by hot air instead of a medical fluid, the secondary contam­ination is never caused by the crushed fine dust.

Abstract: The present invention is concerned with a spread comprising less than 30 wt.% of a continuous fat phase and at least 70 wt.% of an aqueous phase, wherein the spread comprises 0.1 to 1.5 wt.% of a mixture of monoglycerides and polyglycerol esters in a weight ratio of monoglycerides to polyglycerol esters in the range of 1:10 to 10:1. 
     The spreads according to the present invention offer the advantage that processing conditions to be used in manufacturing said spreads are not very critical. After processing, the present spreads are comparatively more stable towards phase inversion than similar spreads containing solely monoglycerides or polyglycerol esters. Furthermore the utilization of mixtures of monoglycerides and polyglycerol esters enables the preparation of very low fat spreads containing a substantial amount of non-gelling protein.

Abstract: A drug delivery system is described in which an immunoconjugate and a prodrug are used in association with each other to deliver a drug to a host target site such as a tumour. The immunoconjugate comprises an antibody or antibody fragment to which is attached a β-lactamase or an active fragment thereof. The prodrug is a cyclic amide derivative of a drug or an unstable precursor thereof in which the drug or precusor is attached to the remainder of the prodrug such that it forms a leaving group which on hydrolysis of the prodrug is eliminated as the active drug or unstable precursor. Particular prodrugs include penicillin or cephalasporin derivatives and other β-lactams to which are attached any physiologically active substances, particularly antineoplastic agents, antiviral, antibacterial or antifungal compounds. In use the immunoconjugate is adminstered first such that it localises at the host target site. Subsequent administration of the prodrug results in β-lactamase catalysed hydrolysis of the prodrug at the target site with release of the active drug or unstable precursor.

Abstract: A photographic film cassette (10) has two light trapping fabric pieces (28) having pile threads, attached each to upper and lower surfaces of the film passageway (26) for trapping light. A ridge (22,24) is formed on an inner surface of the cassette body for preventing the film (14) from loosening. A ridge extended portion extends from the ridge toward the film passage mouth along the upper surface. The inclined portions are formed on both inner surfaces of the film passageway. The film leader is guided to be close to a middle between both fabric pieces during a film advance. In a preferred embodiment, resilient members with pile threads are disposed on inner surfaces of the film passageway. The film can be guided smoothly without resistance of the light trapping fabric. A mechanism is also provided for shielding light in passage through gaps between bottoms of the pile threads. In a preferred embodiment, a narrow is formed at the film passage mouth. In another preferred embodiment, a light-shielding member projects obliquely from the lower surface. In a further preferred embodiment, a recess is formed on the upper surface so that the lower surface is arranged in a position upwardly shifted corresponding to a depth of the recess, which reduces an angle at which light impinges on the coiled film. In yet another preferred embodiment, stepped portions or inclined portions are formed on the upper and lower surfaces. In a still further preferred embodiment, lateral walls of the film passageway are widely spaced near the film passage mouth to shield light in gaps beside the fabric pieces.
