Title: Gas-fired water heater
Inventor: ROE COLIN BARRIE
IPC: F24H1/10
Filed: 1988-11-21
Abstract: A gas fired direct contact water heater 10 includes a reservoir 24 carrying and communicating with an inner casing 14. The inner casing 14 encloses a gas distribution plate 34, heat transfer media 40 supported thereover and a water distribution plate 42. An outer casing 12 is provided around inner casing 14 so as to define an annular gap 16 which is supplied with cold water via water inlet 20.

Title: An electronic multi-shaft absolute position detecting device
Inventor: TSAI YOU-KUNG
IPC: G01B7/00
Filed: 1991-05-25
Abstract: An electronic multi-shaft absolute position detecting device, 1 comprising an absolute position recording circuit 11, an interface circuit 12, a spare power circuit 13, and a cooperating application software circuit, detects incremental position signals produced by a measuring system 3 associated with a numerically controlled machine tool and converts the signals into absolute position signals to thereby record machine-part position values. In case of a power cut, the spare power circuit 13 can provide the absolute position recording circuit 11 and interface circuit 12 with power so that the absolute position recording circuit 11 can continuously detect the position signals produced by the measuring system 3 and record the position values thereof. After the power supply is restored, the absolute position recording circuit 11 can respond to the requirement of a numerical control system 2 to read the final position values of the machine when the power is restored and transmit the final position values to the numerical control system 2 through the interface circuit 12, making the machine tool automatically restore to continue the original processing operation. <IMAGE>

Title: A device for splicing strips of limited transverse dimensions automatically
Inventor: BORIANI SILVANO
IPC: B65H19/18
Filed: 1992-09-29
Abstract: The trailing end of a narrow web 3 (eg wrapper tear strip material), being unwound from expiring reel 2 and fed via grooved rollers 18, 17 and web-reserve 30, is spliced to the leading end of a web 5 from standby reel 4. Prior to splicing, the leading end of web 5 is held by suction in a groove 11 of splicing component 10, a out having been made at 13. When a detector (not shown) generates at 49 a roll-depletion signal, component 10 moves towards splicing component 12, part of which enters groove 11 to urge webs 3 and 5 into contact, splicing being effected by heat sealing or adhesive. Roller 17 is moved to the broken line position to cause cutting of web 3 at 14. In a modification, there are web conveyor belts incorporated into splicing components 10 and 12. Reels 2 and 4 have independent drives 31, 33, 34 linked to control means 50. <IMAGE>

Title: Joints in window frames formed from metal extrusions
Inventor: TANG SUEE PI
IPC: E06B3/964
Filed: 1992-10-21
Abstract: A window frame comprises lengths of metal extrusion cut from longer extrusions, the extrusions being cut in a plane perpendicular to their long axes, and connecting pieces acting so as to form joints between the lengths of metal extrusion. The connecting pieces have at least one tongue complementary in shape to a cavity formed within the lengths of extrusions such that the tongue may be received by a cavity in a length of extrusion so as to form the desired joint. By joining lengths of extrusion cut in this way, the wastage associated with the conventional means of joining lengths of extrusion is avoided. The connecting pieces can be used to form corner-joints, cross-joints and tee-joints in inner and outer window and door frames and can be of ABS, uPVC or wood.

Title: Refresh function in semiconductor memory device
Inventor: KIM MOON-GONE
IPC: G11C11/406
Filed: 1992-11-23
Abstract: A refresh timer 230 generates refresh clock pulses RFCLK from which a counter 250 forms signals Q0, Q1, Q2, Q3 of different frequency to one another, one of these signals 03 being applied to both a circuit 210, controlling a refresh address counter 220, and to a selection circuit 350 in a back-bias voltage generator 300. During normal read/ write operations, a driver 320 in generator 300 operates at the frequency of an oscillator 310. During a refresh operation, oscillator 310 is disabled by selection circuit 350 and the driver 320 operates at the frequency of a signal CLKBB which can have a frequency corresponding to any selected one of the counter outputs Q0, Q1, Q2, Q3. The driver frequency is chosen to optimise power consumption during a self-refresh operation and is selected by a logic circuit 400 which includes two fuses (F1), (F2), (Figure 4), each of which can have either an open circuit or a short circuit state, each of the four possible combinations of fuse states causing a corresponding one of the four counter signal frequencies to be selected. Non volatile programmable memory elements may be used instead of the fuses. <IMAGE>
