Title: Acoustic ceilings
Inventor: SCHENACH JOSEF
IPC: E04B9/04
Filed: 1990-09-05
Abstract: The invention provides a system for erecting acoustic ceilings. The system comprises a set of three pre-fabricated components available in commerce. A first component is a perforated or expanded channel shaped metal sheet 12 adapted for accommodating acoustic material 28 such as mineral wool or fibre glass. The second and third components are longitudinal and transverse frame members 14, 20, 18, 16 respectively having any of a U, T, J or an L-shaped cross section. These frame members are adapted to support the first component. Each component has an appropriate surface finish, e.g. coated or anodised. The ceiling is adapted either to be suspended from an overhead structure e.g. by wires 51 or to be attached to the purlins 54 of the overhead structure. At least one of the frame members is attached to a vertical surface 49 thus rendering support. The attachments are effected by pop rivets and/or nails 50. An inverted U-shaped bracket 30 may overlie material 28 to keep it in place. <IMAGE>

Filed: 1990-09-07
Abstract: The drill 1 has an associated presser 2 fitted to the tool support to be placed against the surface to be drilled, and can move axially in relation to the drill guided by pistons 18 and rods. The presser has micrometric screws 24 to cooperate with switches 15. initially the drill to presser distance D1 is set with the drill in a retracted position. Then the screw 24 to switch 15 distance D2 is set by the screws to be equal to D1 plus the drilling depth. The drill and presser are moved, the presser contacting the work and holding it down whilst the drill advances into the work to the required depth. Screw-switch contact reverses feed, the presser still holding the work by springs around the guide rods. <IMAGE>

Filed: 1986-10-22
Abstract: A memory circuit comprises a digital processor 400 having an input port I1 and an output port O1, the output port being connectable to the input port via selectable resistance means R1a-R1c and the input port being connected to a fixed potential via a capacitor C. The processor is arranged to develop a change in voltage at the output port and to sense the corresponding signal at the input port thereby to establish the time taken for the signal at the input port to reach a threshold, the time being indicative of the resistance of the resistance means. The resistance means represent a limited amount of data, e.g. for instrument calibration, where it would be uneconomic to use a conventional PROM. <IMAGE>

Title: Inserting debug instructions into a cpu with on-chip instruction cache.
Inventor: BOUREKAS PHILIP A
IPC: G06F12/08
Filed: 1992-06-04
Abstract: A structure and a method for 'jamming' instructions into a CPU core in a microprocessor with an on-chip cache memory. In one embodiment, the microprocessor provides a debug mode, which is activated by a signal on a mode pin. In the debug mode, when a signal is received on a second mode pin, a cache miss is generated at the next instruction fetch. Thus, the processor is forced to fetch the next instruction from main memory. The external testing device then provides the instruction on the memory bus as though it is fetched from the main memory in response to the read cycle resulting from the cache miss. Thus the contents of the cache are preserved to maintain consistency before and after interruption of the instruction stream. <IMAGE>

Title: Cycle light stick
Inventor: WEGRZYN MICHAL STANISLAW
IPC: B62J6/00
Filed: 1992-11-26
Abstract: The Cycle Light Stick (CLS) is designed not to replace the existing lighting systems, but to enhance their performance in low light situations. The intent of its operation is further to the standard set of lights already available to the cyclist. The CLS puts on display a light source clearly visible from both sides of the cyclist as well as from the front and rear; forming a complete all round display of light, in low light conditions. Because of the positioning of the CLS, mainly inside the cavity of the wheel or the axle space, it produces a dazzling display of light as the wheel or wheels not only rotate but also move forward, on their line of travel. There is also a flashing effect when viewed from the rear quarters of the cycle. <IMAGE>

Title: A programmable pulse generator with phase adjust
Inventor: COX DANIEL R
IPC: H03L7/06
Filed: 1994-07-19
Abstract: A programmable pulse generator for creating a clock signal of variable duty cycle and frequency with a phase adjustment capability is disclosed. To perform phase adjustment, the invention includes a mechanism which allows a frequency "walking" or phase adjust to be inserted by just adding or subtracting one input clock cycle from the high or low pulse at a certain time interval. In one embodiment, the invention uses two programmable counters 11, 13, with only one counter counting at a time. One counter counts input clock pulses to determine the high phase of a generated output signal and the other counter counts input clock pulses to determine the low phase of the output signal. The counters are reset when the count value matches a value set in a register, 71, 73 control logic 51 receiving an input from a processor core includes a phase adjust 55 with M, N count register. Phase adjust is obtained by using a multiplexer 45 to switch registers R2 or R3 in place of R1 to add or subtract a pulse from a high pulse. The generator output may be used for sampling an analog signal at varying instants. <IMAGE>

Title: Laser waveguide
Inventor: TOWNSEND PETER DAVID
IPC: H01S3/063
Filed: 1995-03-22
Abstract: A laser waveguide is made by sputter-depositing an alloy of mainly aluminium and a little dopant e.g. Cr, in an oxidising atmosphere, onto a heated quartz substrate, and preferably annealing to form ruby, which may then be encased in a silica cladding. The dopant may be present in a proportion of 1 mole: 10<2> - 10<4> moles aluminium. During sputter-depositing the waveguide may be maintained at 400 DEG - 700 DEG C. During annealing the atmosphere controls the oxidation state of the dopant. After annealing hydrogen is implanted to control the oxidation state of the dopant. The waveguide may be encased in a cladding overlayer of silica.
