Abstract: An inductive pen (16) repetitively transmits pulses of an oscillatory signal having a characterisitic  frequency. Pen state information,  such as pen tip contact switch information, are encoded by a number of techniques. These techniques  include  pulse  width  modulation  or  pulse position  modulation,   so  as  to  convey  pen  state information to a digitizing tablet in a manner that does not adversely affect pen position determinations. The pen state information may also be encoded on the oscillating signal  by  Frequency  Shift  Keying  (FSK),  Phase  Shift Keying (PSK), or Amplitude Modulation (AM). A digitizer tablet   (10)   includes  circuitry  for  detecting  the transmitted  pen   state   information,   the   circuitry accommodating the selected modulation scheme. The tablet is  responsive  to  the  transmitted  pulses  for  placing tablet circuitry in a low-power consumption state between pulses so as to conserve tablet power.

Abstract: A method of making an end stop for a slider of a fastener structure for a thermoplastic bag. The fastener structure comprises a pair of flexible plastic strips adapted to be connected to the walls of the bag (B) and having reclosable interlocking male and female profile elements (16,17) on the respective strips (14,15) and a slider (10) straddling the strips for opening and closing them. The method comprises clamping together a pair of the flexible plastic strips between clamps (40,41) at a seal area in the region intended to form an end of the strips, the clamps (40a,40b) having pockets (41a,41b) therein adjacent the profile elements at the seal area. The profile elements are severed and heated at the seal area with a heated knife (45) to transform the severed ends of the profile elements into molten material; the molten material is pressed into the pockets in the clamps (40,41) with the heated knife (45) thereby increasing the thickness of an area of the strips adjacent the seal area to provide a protruding end stop for preventing movement of the slider past the ends of the bag (30). <IMAGE>

Abstract: ABSTRACT     In a terminal screw for the electrical connection of cables or wires, in particular cables or wires provided with ear-shaped cable terminals, said terminal screw comprising a housing (10 and a clamping screw (8) which, in the screw-in direction, penetrates through a first clamping plate (9, 16) and, when the terminal is closed, through a second clamping plate (11), the first clamping plate (9, 16) is arranged to be non-rotatable and axially non-displaceable, whereas the second clamping plate (11) is guided to be non-rotatable and axially displaceable in the housing (10). In the fully open position of the terminal, the second clamping plate (11) abuts against a limit stop of the housing (10) and is held in this position by a resistance which can be overcome by the clamping screw (8), with the result that the opening is kept open for the insertion of the cable or the cable terminal. The clamping screw (8) is screw-connectable in a bore (17) of the first clamping plate (9, 16) until it engages with the second clamping plate (11). In this regard, the bore (17) of the first clamping plate (9, 16) is designed to be without an internal screw thread, and projections (14 or 25) are provided which engage only in the screw threads of the clamping screw (8).

IPC: E04H12/10
Filed: 1990-10-29
Abstract: Abstract A modular steel utility structure and a method of assembly is disclosed.  The construction employs a plurality of vertical steel columns and horizontal frames.  Each column has capital and basal steel erection plates secured at respective upper and lower ends.  The capital plate has from one to four pins extending upwardly therefrom and laterally off-set from the column. Each basal plate has a corresponding number of apertures similarly spaced from the column.  Each frame has a top and bottom erection plate secured at each corner thereof. The bottom erection plate has an aperture spaced from the frame members for receiving the pin from a capital plate of a column immediately therebeneath for registration therewith.  The top erection plate has an upwardly projecting pin which is received in register by the aperture on a basal plate of a column in the story or level immediately above it.  In this manner, the structure is assembled by positioning a story or level of columns with a crane, and then by placing the prefabricated frames in position to be supported by the columns.  Additional stories are added by successively positioning tiers of columns and frames.  The adjacent erection plates on the columns and frames may be bolted together or otherwise secured for additional stability.

Abstract: ABSTRACT     A method of monitoring nuclear radiation comprises providing a diamond radiation sensor element having a nitrogen impurity concentration of less than 150 ppm. The sensor element is subjected to nuclear radiation, while being stimulated with light of a selected wavelength or range of wavelengths, preferably in the ultraviolet or near- ultraviolet range, resulting in light emissions from the sensor element. Typically, the sensor element is fixed to the end of an optical fibre, the far end of the fibre being used to channel stimulating light to the sensor element and to feed resultant light emissions from the sensor element to a photomultiplier tube. The invention includes apparatus for carrying out the method.
