Title: Control method for a direct-coupling mechanism for a torque converter or fluid coupling of an automatic vehicle transmission
Inventor: NISHIKAWA MASIO
IPC: F16H61/14
Filed: 1986-06-13
Abstract: A method of controlling a direct-coupling mechanism of a hydraulic torque converter of an automatic transmission for an automotive vehicle, wherein the transmission capacity of the direct-coupling mechanism is controlled such that the value of a first predetermined parameter indicative of an amount of relative slip between input and output members of the hydraulic torque converter which are mechanically engaged with each other by the direct-coupling mechanism lies within a predetermined reference range. The value of a second predetermined parameter indicative of one of said plurality operating modes for the automotive vehicle is detected. Determined in dependence on the detected value of the second predetermined parameter is either the predetermined reference range of the value of the first predetermined parameter or a rate at which the transmission capacity is controlled such that the value of said predetermined parameter changes toward the predetermined reference range of the first predetermined parameter.

Title: A dual stage dynamic rock stabilizing fixture and method of anchoring the fixture in rock formations
Inventor: SCOTT JAMES J
IPC: E21D20/02
Filed: 1986-11-25
Abstract: A dual stage dynamic rock stabilizing fixture for insertion in a bore hole in a geologic structure, the fixture combining a dynamic compressible plastic formable material (13) and an activatable bonding material (14) in various cooperating arrangements which upon insertion of an anchor rod will perform an initial stabilization of the rock structure through the compression of the formable material by the anchor rod in advance of a subsequent stabilization effect upon setting up of the activatable bonding material through mixing action of a suitable surface configuration on the anchor rod. The fixtures hereof are designed to carry out the steps of a method of inserting the combined formable material and the bonding material into a bore hole, and using an anchor rod to establish a rapid first stage of rock stabilization through the formable material which creates a dynamic support and a second stage of rock stabilization from the activatable bonding material which creates a high modulus stiff anchor. <IMAGE>

IPC: G06K19/06
Filed: 1987-02-20
Abstract: A card or badge carries data in binary form by providing windows of high and low transmissivity to infra-red radiation. The high transmissivity windows are transparent whereas the low transmissivity windows are partially obscured by two groups of spaced opaque areas each extending partially across the window. The areas are printed on a surface which will be in the interior of the finished card by means for example of a thermal dot printer. One group of areas is printed by energising a first group of dot printing elements and the other group of areas is printed by energising a second group of elements, the arrangement of the areas being such that the two groups of printing elements have approximately equal duty cycles. <IMAGE>

Title: Ion beam arrangement
Inventor: BARRETT NEIL JOHN
IPC: H05H9/00
Filed: 1987-08-28
Abstract: An ion beam arrangement including means for receiving the steady ion beam and for accelerating it and converting it into a sequence of discrete bunches of ions having a velocity distribution which is small compared to the mean velocity of the ions comprising a series of electrode tubes and drift tubes. The length of the electrode tubes and the acceleration gaps between them are chosen in relation to the alternating voltages applied to produce a particular and predetermined energy distribution in the bunched ion beam which emerges at the output end of the drift tube 27. Ions from an ion source (not shown) pass through earthed tube 1 and are accelerated or retarded by the field due to the HF signal applied to tube 2, and in long drift tube 3 ions of similar velocity are separated into discrete bunches. The separate bunches of ions arrive at drift tube 4 such that the phase of the HF signal applied thereto accelerates each bunch as a whole, the bunches then being fed to an accelerator having two stages 24, 25 to import the required energy distribution to each bunch. <IMAGE>

IPC: C06B45/12
Filed: 1988-03-29
Abstract: A pyrotechnic device characterised in that it comprises applied to at least a portion of an outer surface thereof and/or visibly incorporated therein one or more phosphorescent materials is disclosed. As fireworks in particular are usually used from dusk onwards and other pyrotechnics may be used in conditions of poor illumination, it is a clear advantage to the user both in terms of safety and convenience for at least some part of the device, particularly a touchpaper or ignition point, to "glow-in-the-dark", i.e. phosphoresce. Although possessing a surprising advantage, the present devices may generally be used in a conventional manner.

Title: A pedal and crank drive arrangement
Inventor: LAWRENCE MALCOLM GEOFFREY
IPC: B62M3/04
Filed: 1990-04-26

Title: A thermal starter switch for fluorescent lights
Inventor: CHIANG CHUN SHU
IPC: H05B41/08
Filed: 1990-04-27
Abstract: A thermal starter switch for a fluorescent light comprises a housing 10 enclosing a gas filled starter bulb 20 containing a pair of normally closed switch contacts 21a, 21 b which are connected by respective connecting leads 23, 24 to two terminals 40 inserted into the housing 10.

Title: Controlling the operation of a computer to handle interrupts
Inventor: WILSON NEIL
IPC: G06F13/26
Filed: 1990-09-13
Abstract: A method for controlling the operation of a computer to handle interrupts comprises comparing the priority of an interrupt with the priority of a task being carried out by the computer. The task being carried out is suspended if the priority of the interrupt is higher than that of the task, and the interrupt is run. An interrupt counter is incremented by 1 on each interrupt being run. On completion of an interrupt, the counter is decremented by one and the computer is returned to the task which had been interrupted. A reschedule flag is set on an interrupt calling for a rescheduling of the tasks being carried out in the foreground process of the computer. A reschedule flag causes the foreground process to be rescheduled before the computer returns to the foreground process. <IMAGE>
