Title: Shoulder strap for carrying personal communications devices
Inventor: BRISEBOIS PAUL J
IPC: A45F3/14
Filed: 1996-03-27
Abstract: A shoulder strap which encircles the shoulder,and  closes to form a loop at the bottom to accommodate the carriaqe of one or more personal communication devices. The strap is equipped with pouches or horizontal members, or combinations of these to allow the carriage of pagers , portable wireless telephones or hand-held radios directly below the shoulder of the wearer to enable ease of reach with either hand. The shoulder strap is fixed in length for support and has resilient sections to enhance body fit, and comfort of movement when worn. Extended from the shoulder strap at a fixed point near the top of the shoulder is an adjustable and pliant retaining strap which crosses the back, extends over the opposite shoulder, down the front of the shoulder and under to the back again, then across the back to return to the shoulder strap, thru an adjustment and elastic member, to a fixed point lower than the original starting point.  Similarly, the restraining strap may be routed from the upper tie down location across the back and under the arm, up in front and over the shoulder across the back to the lower position on the shoulder strap. This cross-over creates less stress behind the neck of the wearer when heavier personal communication devices are being worn. The personal communication device pouch may be attached at the intersection of the front and back members of the shoulder strap, at a point directly below the shoulder supporting it, a few inches above the waist line of the wearer.  A horizontal member or strap in the same area and higher up near the shoulder will accommodate a pager and/or a pouch equipped with a clip. A pliant and adjustable tie down strap is suspended from the lower extremity of the shoulder strap in such a way as to form a loop about a belt if the wearer has one, or to accommodate a suspender type clip for attaching to a waistband or other clothing device. The shoulder strap is thus designed to bring the personal communication devices close to the center of the wearer, for ease of reach and ease of detection, especially for northern climates where winter clothing may be left open at the front to allow use and improve the hearing of incoming calls as compared to existing designs. This will also expand in scope in high noise level areas as will be discussed later.

Inventor: JAHNKE FREDERICK CHARLES
IPC: C10K3/00
Filed: 1994-10-18
Abstract: A highly efficient partial oxidation process with the production of power comprising the steps of producing fuel gas by the partial oxidation of hydrocarbonaceous fuel, cooling said fuel gas at high pressure by quenching in water to produce quenched fuel gas and by indirect heat exchange with BFW to maximize the production of IP and MP steam, cleaning said fuel gas, preheating scrubbing water comprising process condensate and make-up water by direct contact and direct heat exchange with clean fuel gas and using said preheated scrubbing water in the cleaning of said fuel gas, reducing the pressure of said cooled fuel gas stream prior to heating water for fuel gas saturation, cooling the process fuel gas stream in stages and condensing water for use as said scrubbing water, purifying the process fuel gas and saturating it with water, and burning said purified and saturated fuel gas in the combustor of a power-producing gas turbine along with saturated nitrogen to produce exhaust gas with a reduced NOx. In one embodiment, the hot exhaust gas from the gas turbine is passed through an HRSG to superheat the process steam. The superheated process steam is then used as part of the working fluid in an expansion turbine for the production of power. Steam condensate may be converted into high pressure (HP) steam and superheated in the HRSG. The superheated HP steam is then passed through an HP expansion turbine as the working fluid. The power generation steam cycle is optimized to assist in maximizing the process steam which can be used most efficiently in the cycle.

Title: Apparatus for reconstructing holographic images
Inventor: HART STEPHEN J
IPC: G03H1/22
Filed: 1994-11-28
Abstract: An apparatus for reconstructing holographic images includes a white light source, diffraction grating (1112) for generating zero-order diffracted light (1416) and at least first-order diffracted light, and light control film  (LCF 1810) which is configured to block the zero-order diffracted light and to facilitate passage of a desired bandwidth of first-order diffracted light therethrough.  In one embodiment light control film (LCF 1810) comprises a front layer (1802), a core layer (1804), and a back layer (1806).  The back layer (1806) may be thought of as a datum, whereby a lateral shift in front film (1802) results in wavelength selectively, and a corresponding shift in core layer (1804) results in good zero-order light blocking.  The resulting light is a pseudo-monochromatic source having sufficient coherence for use as a hologram reconstruction beam.

Title: Method of converting a series of m-bit information words to a modulated signal, method of producing a record carrier, coding device, decoding device, recording device, reading device, signal, as well as a record carrier
Inventor: SCHOUHAMER IMMINK KORNELIS ANT
IPC: H03M7/14
Filed: 1995-02-01
Abstract: The Patent Applications relates to a method of converting a series of m-bit information words (1) to a modulated signal (7). For each information word from the series an n-bit code word (4) is delivered. The delivered code words (4) are converted to the modulated signal (7). The code words (4) are distributed over at least one group (G11, G12) of a first type and at least one group (G2) of a second type. For the delivery of each of the code words belonging to the group (G11, G12) of the first type the associated group establishes a coding state (S1, S4) of the first type. When each of the code words (4) belonging to the group (G2) of the second type is delivered, a coding state (S2, S3) of the second type is established which is determined by an information word belonging to the delivered code word. When one of the code words (4) is assigned to the received information word (1), this code word is selected from a set (V1, V2, V3, V4) of code words which depends on the coding states (S1, S2, S3, S4). The sets of code words (V2, V3) belonging to the coding states (S1, S2) of the second type are disjunct. In this coding method the number of unique bit combinations that may be established by the code words in the series are enlarged. The modulated signal (7) thus obtained may be reconverted to information words (4) by first converting the modulated signal (7) to a series of code words (4) and then assigning an information word (1) to each of the code words from the series in dependence on the code word to be converted and also in dependence on the logical values of the bit string bits which are situated at predetermined positions relative to the code word. Furthermore, a recording device and a reading device are disclosed.
