Patent CA-2069236-A1 (CA)
Inventor: KOMODA MOTOYOSHI
IPC: H04W24/06
Filed: 1992-05-22
Abstract: The present invention relates to a self-diagnosing method which shortens the diagnosing time for a ROM which is provided within a mobile telephone set for use in a mobile telephone switching system and mobile telephone set being applied the method.  When the power supply is turned ON, a complementary value which complements to set up the sum of data stored  within all the addresses of the ROM as a certain specific value, ROMCHK, which is the content of the data stored within a specific address of the ROM, is compared with NVMCHK which is the content of data stored previously within a specific address of a non-volatile memory with the same value as the ROMCHK.  If they do not coincide, then the content of the data within the entire area of the ROM is calculated for the diagnosis.  In this case, the content stored within the specific address of the ROM is the sum of the data values within the entire area of the ROM, and the content stored within the specific address of the non-volatile memory is the same as this sum value.

Abstract: An antenna, which may be used for transmission or reception of electromagnetic radiation, comprises a dish (1) shaped reflector for collecting radiation when used as a receiver. The dish (1) is wholly or partially transparent to visible light. Because the dish (1) is transparent it may be mounted on a house (2) without obstructing a view of or from the building. The dish (1) comprises a gauze (6) which is reflective to a particular band of micro-wave radiation carrying a video signal. The gauze (6) may be sandwiched between two plastics laminae (50 and 51). Alternatively the dish (1) may have a permanent substance (52) printed or coated on its surface. This substance would be transparent to visible light but reflective to the particular band of electromagnetic radiation carrying a video signal. In an alternative embodiment the dish (1) is supported on a building with a transparent support (100).

Patent CA-2099760-A1 (CA)
Inventor: GALCHEFSKI JOHN M
IPC: B29C63/06
Filed: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus (10) for applying thin film polymer labels onto small cylindrical articles includes a label transport drum (20) that is constructed for aiding the transfer of a label onto a cylindrical article.  The apparatus includes a label transport drum (20) having a cylindrically configured hub (44) and cylindrical drum (50) mounted on the hub (44) for rotation thereabout.  The drum (50) has an outer surface on which labels are fed while the drum (50) is rotated about the hub.  A first radially extending, slotted vacuum manifold 556) defines a label retention area (58) and extends circumferentially around a substantial portion of the circumference of the hub (44).  A first radially extending slotted pressure manifold (56) is aligned circumferentially after the slotted vacuum manifold (56) at an article wrapping position (22).  A valve port (62), circumferentially aligned with the vacuum and pressure manifolds (56, 60) is positioned on the inner surface of the drum (20) and communicates with the area on the drum surface where the leading edge of the label lies.  As the drum rotates, the valve port (621 aligns with the vacuum manifold (56) and draws a vacuum onto the label to retain the label onto the drum.  As the drum (20) rotates further the valve port (62) aligns with the pressure manifold (60) to blow air onto the leading edge of the label to force the label outwardly from the drum surface onto an article thereat to aid in label transfer.  A second vacuum manifold (80) and valve port (82) draw vacuum onto the label to retain the label on the drum surface past the article wrapping position (22) if an article is not wrapped.  The label is blown from the drum surface if an article misfeeds.

Title: Pump jack scaffold
Inventor: LUBINSKI RONALD
IPC: E04G1/20
Filed: 1993-12-14
Abstract: ABSTRACT OF THE DISCLOSURE             A pump jack scaffold includes a pair of extruded aluminum poles. Each pole has a rectangular cross-section. Wood is adhered to one side wall of each pole, providing a surface a jack mechanism can grip. Each of the other three side walls is extruded with a longitudinal structure, internal to the pole, which defines a lengthwise T-slot opening into the exterior of the associated sidewall. Bolts are insert into the T-slots to fasten braces, which can be used either to engage an adjacent building structure, to join the uprights to define a more unitary structure, or to render the scaffold self-supporting. Each pole is separable into upper and lower sections for transportation. The sections are joined by a resilient internal bridging member which is extruded of aluminum. It has an elongate central portion, webs extending radially from the central part, and a bracing portion terminating each web and engaging a corner of the pole. Upper and lower locking pins extend through aligned openings formed in the pole sections and the bridging member to secure the sections. The bracing portions are spaced to define longitudinal slots that closely receive the internal longitudinal structures extruded with the pole, reinforcing the pole against twisting.
