Title: Grease-absorbent microwave cooking pad and package
Inventor: ISAKSON GARY A
IPC: A47J47/00
Filed: 1992-08-28
Abstract: GREASE-ABSORBENT MICROWAVE COOKING PAD AND PACKAGE             ABSTRACT OF THE DISCLOSURE         A pad for use in the cooking of food placed thereon in a microwave oven is disclosed.  The pad is specifically designed for use in connection with food, (e.g., bacon strips) that contains a substantial amount of solidified grease which melts when the food is cooked by microwave radiation.  The pad is formed from an entangled web formed from at least one generally hydrophobic and grease absorbing multilayer microfiber. The web is formed by combining at least two streams of flowable polymer materials (e.g., polypropylene and polyethylene terephthlate) in a layered, combined flowstream, extruding the combined flowstream through a die having at least one orifice, attenuating the extruding flowstream with a high velocity gaseous stream to form fiber, and collecting the fiber on a collective surface so as to form the entangled web.  A pad so formed is capable of holding the amount of grease in the food placed thereon when the grease is heated by cooking the food in a microwave oven.            A:946-7A.CAN

Title: Slide-proof spigot-and-socket joint
Inventor: IMHOF ERICH
IPC: F16L21/08
Filed: 1992-10-15
Abstract: The spigot-and-socket point which is secured against sliding is designated for moulded parts and for socket pipes (1) produced by the centrifgual casting technique, with the spigot end (3) of the one pipe adapted to be slid, with radial play, into the socket end (2) of the other pipe. In the socket end there are arranged a sealing ring (8) and a separate clamping ring (14) comprising a plurality of circumferentially extending, spaced clamping segments (15) having a spherically convex outer surface (17) and, on their inner surface (18), a tooth system (19) which, in the presence of axial forces, presses radially onto the spigot end (3) as the spherically convex surface (17) cooperates with a pipe socket's inner surface (18) which tapers conically towards the end. An elastomer support member (20), which can be fixed in its position at the socket face end and supports the same, is provided on the clamping ring (14). A form, which ensures proper retention also in the case of increased rated widths, is obtained when the support member's annular disk-shaped portion (23), which bears on the socket front face (22), comprises a reinforced transition region (26) of increased flexural strength in the region of the inner edge of the socket front face, with the portion (24) connecting to the clamping ring (14 issuing therefrom, and when the socket front face (22) has at its inner edge a recess matching the cross section of the reinforced transition region (26). There a steel ring (28), which increases the flexural strength and can be optionally inserted via an axial insertion slit (29), is cooperating with the reinforced transition region (26) of the support member.

Title: Method and Apparatus for Communicating Interleaved Data
Inventor: PAIK WOO H
IPC: H03M13/27
Filed: 1993-06-18
Abstract: An interleaver (34) processes information in a pseudorandom order to provide pseudorandom interleaved data for communication to a deinterleaver (42). The pseudorandom interleaved data is processed at the deinterleaver (42) in a pseudorandom order corresponding to that used at the interleaver (34) means, to recover the original information. The pseudorandom processing at the deinterleaver is synchronized with the pseudorandom processing at the interleaver on a trial and error basis. In one embodiment, full synchronization occurs when a Viterbi decoder (44) receiving data from the deinterleaver has a renormalization rate within a designated threshold and when enough synchronization words are detected in data output from the deinterleaver to meet a predetermined criterion. In another embodiment, a timer is used to initiate a new starting address for the pseudorandom processing at the deinterleaver during successive time intervals. Synchronization is achieved when a start address is found that results in the detection of enough synchronization words in data output from the deinterleaver to meet a predetermined synchronization criterion. <IMAGE>

Inventor: YOUNES MAGDY
IPC: H05K3/10
Filed: 1992-02-12
Abstract: Improvements in piston-based ventilator design and operation are described. In one aspect, individual compensation of force dissipation within the gas delivery system is effected, so that the desired gas pressure is delivered to the patient airway with-out the necessity for monitoring the actual pressure and using it as feedback. In another aspect, a piston (14) is dimensioned slightly less than the chamber wall (12) of the pump to define a gap (18) through which an acceptable amount of gas may leak but which eliminates the need for a physical seal, thereby minimizing the frictional resistance within the pump.

Title: Doubling the number of raster lines in television receivers at the frame rate
Inventor: SID-AHMED MAHER A
IPC: H04N5/44
Filed: 1993-08-23
Abstract: ABSTRACT OF THE DISCLOSURE    This invention is a circuit for doubling the number of raster lines in television receivers without the need for change in the transmission standards. The concept relates to improved definition television (IDTV) or enhanced definition television (EDTV). With this invention the number of lines and the resolution per line can be doubled as many times as technology permits. The circuit is based on the use of two read-write memory arrays or memory buffers and an interpolation circuit. One memory array is used to store one image, while data is being read from the other memory array. The image being read from one of the arrays is interpolated through an interpolation circuit. The role of the two memory arrays changes with every incoming image, the memory array that was in the read mode is switched to the write mode and vice-versa. The interpola-tion is carried-out through pixel replication in two-dimensions followed by a square symmetrical two-dimensional low-pass filter, which provides interpolation based on the Sampling Theorem. This could also be followed by a two-dimensional  (2-D)  circularly-symmetrical high-pass filter for image enhancement. A description of a circuit realizing a 2-D infinite impulse response filter and the filter coefficients for a square symmetrical low-pass filter having near linear phase is provided. Circuits for addressing the two memory arrays are described. The incoming image is assumed to be formed of two interlaced frames. Circuit designs are provided for displaying video images through either progressive or inter-laced scanning.     Interpolation  could  also  be  carried-out  through  a  one-dimensional (1-D) filter, or through the Discrete Cosine transform. These other possible variations are described in the preferred embodiment.

Title: Internally flashed siding channel
Inventor: VAGEDES MICHAEL
IPC: F24F13/08
Filed: 1993-09-09
Abstract: A channel for lapped siding includes an elongated nailing strip and an abutment strip with an upper cover strip. This provides a generally C-shaped cross-section. Inside the channel is a rectangular tab that extends at an angle away from the nailing strip up to the cover strip.      The channel is nailed to a building. Lapped siding is also nailed to the building with edges of the siding positioned in the channel. The edge of the siding is slit horizontally to allow the tab to intersect the edge of the siding. Any water that gets into the channel will run along this tab away from the building wall to an exterior surface of the siding. This keeps the water from flowing behind the siding.
