Patent GB-2248451-A (GB)
Title: Process for aftertreating anionically dyed substrates
Inventor: KAUL BANSAI LAL
IPC: D06P3/32
Filed: 1991-10-01
Abstract: A process for aftertreating an anionically-dyed substrate selected from synthetic polyamide, cellulose and cellulose derivatives and leather, is characterized in that the substrate is aftertreated with a solution or dispersion containing one or more cycloaliphatic compounds containing a sterically hindered amine group, which may also be protonated (herein referred to as HALS compounds). The substrate may be in the form of fibres, or chips or granules which are later worked into fibres or other forms. The sterically hindered amine groups of the HALS compounds are preferably bound to a carbocyclic group of aromatic character by means of an ester or amide group or are attached by an amino, imino or ether group to a heterocyclic group (preferably triazine). Preferred HALS compounds have one or more 2,2,6,6-tetramethylpiperidyl-4 or 1,2,2,6,6-pentamethyl piperidyl-4 groupings. The sterically hindered amine groups form salts with the anionic dyestuffs and this improves the migration and wash fastness properties.

Title: Laser printer interface.
Inventor: YANG JEN-TSUN
IPC: G06F3/12
Filed: 1992-05-12
Abstract: An interface adapted to couple a laser printer to the printer port of a computer includes a first in first out memory, a shift register, control logic, a pulse generator and a command/status controller. The first in first out memory stores the data sent from the printer port of the computer. The shift register converts the parallel data to a serial 'video' signal. The control logic monitors the video signal, and generates a control signal to the first in first out memory and the shift register. The pulse generator monitors the status of the 8th data line of the data bus, and generates a pulse signal to the first in first out memory to store the data on data bus D0-D6. <IMAGE>

Title: Preventing coincidence of fuel injection pulses
Inventor: MATSUURA TAKASHI
IPC: F02D41/30
Filed: 1993-09-23
Abstract: An ic engine fuel injection system wherein when injection pulses to successive cylinders X,Y coincide, the timing of the injection pulse to the succeeding cylinder Y is made to be earlier (figure 5) or later (figure 6) than the injection period to the preceding cylinder X in the cycle. The coincidence of the timing of the injection pulses may occur as a result of a transition from stratified to homogeneous combustion conditions when the engine changes between low and high load conditions. The system avoids an increase in the electric load on the injection system that may otherwise result from simultaneous injection into more than one cylinder under such conditions. <IMAGE>

IPC: H01J23/033
Filed: 1993-11-25
Abstract: An electron collector is provided for collecting spent electrons generated by a charged particle device after passage through an interaction region of a RF circuit. The collector has a centerline (14) and comprises an outer structure (24) which is coupled to the RF circuit. An inner structure (26) within the outer structure (24) receives the spent electrons. A negative voltage is applied to the inner structure (26), which forms an electric field between the inner and outer structures. A plurality of thermally conductive and electrically insulative standoff assemblies (30) extend between the outer and inner structures. Each of the assemblies comprise a ceramic planar member (34), centered within an outer wall (36) providing a double-ended cup shape, and conductive plugs (42, 52) which adjoin each side of the planar member with respective ones of the inner and outer structures. Since the conductive plugs (42, 52) are partially surrounded by the outer walls, a relatively long surface voltage breakdown path is provided between the plugs (42, 52), while the thermal path through the planar member (34) is relatively short. <IMAGE>

Title: Magnetic head
Inventor: NISHIMURA MASARU
IPC: G11B5/265
Filed: 1994-02-03
Abstract: In a magnetic head comprising a read/write head and an erase head constructionally integrated with each other, the closed magnetic circuit of the erase head (11) is arranged to be higher in magnetic reluctance than the closed magnetic circuit of the read/write head (1), whereby a magnetic flux to be drawn by the erase gap is reduced so as to prevent the leakage of the magnetic flux to the read/write head side. This is achieved by having a cross-section area in the erase circuit (S1) less than any cross-section in the read/write circuit. The area may be reduced by roughening a contact surface or by positioning of non-magnetic spacers. <IMAGE>
