Title: Boiler associated with a ventilator
Inventor: DOBRUCKI DOUGLAS ANDREW
IPC: F24D19/10
Filed: 1991-11-16
Abstract: A gas-fired appliance 74 e.g. a boiler is associated with ventilating apparatus 80 mounted over an air vent 78 in a wall the apparatus 80 having a fan and an air flow sensitive switch, the arrangement being such that when the appliance is switched on e.g. by a time switch 76, the fan is first brought into operation to draw air through the vent in quantities sufficient to activate the air flow sensitive switch which then allows ignition of the gas in the appliance. The vent 78 is a standard size wall air vent. The apparatus 80 may include a thermostatically actuated electric and/or water-to-air heater and a dust or insect filter. The water-to-air heat exchanger may be shaped like a grille and adapted to fit over the air vent. <IMAGE>

Title: Time switch speech-store module
Inventor: COHEN JEREMY LAURENCE
IPC: H04Q11/08
Filed: 1992-03-20
Abstract: A time switch, suitable for switching the locations of time slats within TDM frames, comprises a control store 12 having one storage location for each slot of a relevant frame length, and a traffic store 14 having a number of storage locations equal to twice the maximum switching distance, and further comprises an address counter 16, 18 for each store. The switch uses less RAM than prior switches and has a delay that can be adjusted in software. A time switch may be operated by reading from a control store the location address of data within a frame, adding 28 to the address a delay corresponding to the period between writing to traffic store 14 and reading therefrom, subtracting 30 the sum of the address and the delay from the location address, and subtracting this result from the location address of data stored in the traffic store to determine the read address for data within the traffic store. The switch may be used as a speech store module in synchronous Digital Hierarchy (SDH). <IMAGE>

Title: Hall effect semiconductor memory cell
Inventor: MATTHEWS JAMES A
IPC: H01L21/8246
Filed: 1992-06-25
Abstract: A non-volatile, static magnetic memory device (10), whose operation is based on the Hall effect, is disclosed. The device includes a magnetic patch (33) which stores data in the form of a magnetic field, a semiconductor Hall bar (14, 15 and 17) and a pair of integrally-formed bipolar transistors (28 and 29) used for amplifying and buffering the Hall voltage produced along the Hall bar. Current is forced to flow down the length of the Hall bar causing a Hall voltage to be developed in a direction transverse to the direction of both the magnetic field and the current. The bases (18 and 19) of the bipolar transistors (28 and 29) are ohmically coupled to the Hall bar to sense the Hall voltage, the polarity of which is representative of the stored information. A system of current carrying conductors is employed for writing data to individual magnetic patches. <IMAGE>
Patent GB-2261967-A (GB)
Title: Apparatus for maintaining and supporting system status
Inventor: HAM DAE-HO
IPC: G06F11/32
Filed: 1992-06-30
Abstract: A system maintenance and support processor board 40' is provided with different ports P1, P2, P3 for a console 60, a CPU board 30' and a modem 70, and includes a selective switching circuit (fig 4 not shown) for selectively connecting ports in accordance with different modes of operation. In a system maintenance and support mode where information relating to system faults is relayed to a user who can then take appropriate action, data processed in the system maintenance and support processor board 40' is supplied to the console 60 via a serial input/output controller 90'. In a normal processing mode, data obtained from the CPU board 30' is transmitted to the console 60 and in a remote maintenance and support mode, the modem 70 is selectively connected to the CPU and system maintenance and support processor boards 30' and 40'. This system arrangement allows a single console to be shared between two processor boards and the status of the system can be monitored without having to use the system bus 100', thus, reducing the cost and size of the system and enhancing the system performance. <IMAGE>

Title: Memory card backup control circuit
Inventor: NISHIOKA KOICHI
IPC: G06F12/16
Filed: 1993-05-28
Abstract: During backup, the chip select signal outputs of the decoder 100 are forced into a high-impedance state by the backup signal 9a. The chip select lines for the volatile memories 2 are pulled up 20 to the backed-up supply 6, but the chip select lines 8 for the ROMs 3 are pulled-up 30 to the volatile supply 5. If the ROM select lines were pulled up to the backed-up supply 6, current would flow into the unpowered ICs 3 during backup, increasing battery 4 power drain and reducing reliability. The write enable signals for ROMs such as EEPROMS or OTPROMS may also be pulled-up to the volatile supply (fig. 6). <IMAGE>

Patent GB-2275790-A (GB)
Title: Preclosed cardboard slide mount
Inventor: TRUC JAMES A
IPC: G03B21/64
Filed: 1994-01-18
Abstract: A cardboard slide mount includes a base (16), a cover (12) and a pocket (14) between the base and the cover. The base and cover, which include aligned film windows 20, form opposing first and second rectangular flames for a film transparency, with the pocket (14) forming a nest for the film transparency. Outer corners of the base are rounded. Opposing inner surfaces of the base and cover are adhesively bonded together about three sides (62C, 62D) so that a fourth side defines an insertion opening. The insertion opening allows the film transparency to be inserted into the film nest. A chamfered outer corner of the cover exposes a rounded corner of the base, which permits an opening assembly to separate the base from the cover along the fourth side and thereby allow a film transparency to pass through the insertion opening and into the film nest. A first adhesive region, preferably heat-sensitive adhesive, thereafter connects the opposing inner surfaces of the base and cover along the fourth side. A second adhesive region (64A), preferably pressure sensitive adhesive, in the film nest secures one edge of the film transparency so as to maintain an alignment of the film transparency and the film windows. <IMAGE>
