Title: Float operated flow control valve
Inventor: BARKER JOHN CHARLES
IPC: E03B11/00
Filed: 1996-12-16
Abstract: A valve body 13 is coupled to a float 1 via a pivoted arm 10. The float has a sealed buoyancy chamber 2 and an open-topped liquid chamber 3 provided with a restricted outlet 6, 7. The valve controls flow of liquid from a port 16 into the chamber 3 so that when the float falls with a level of liquid 17 the weight of liquid in the chamber 3 causes the float to drop to a relatively low level. The filling rate is therefore increased. When the water level rises and flow stops, the chamber 3 drains through the holes 6 and 7 so that the float rises relative to the liquid level 17 and produces a swift, noise-free termination of flow. The arm 10 is arranged to conduct liquid from the valve outlet to the chamber 3.

Patent GB-2310742-A (GB)
Title: Trap system for recovery from error
Inventor: LESARTRE GREGG
IPC: G06F11/14
Filed: 1997-02-07
Abstract: A panic trap system recovers from inaccurate results produced from out of order execution of instructions in a processor. The system includes a fetch mechanism (IFETCH) (28) that fetches instructions from an instruction cache. Two queues receive the fetched instructions and execute them out of order. Specifically, an ALU instruction queue (AQUEUE) (38a) receives instructions that are directed to the ALU. A memory instruction queue (MQUEUE) (38b) receives instructions that are directed to a data cache (DCACHE) (24) or a main memory. The MQUEUE includes instruction registers and corresponding address reorder buffer slots (ARBSLOTs) for receiving memory instructions and data addresses corresponding to the results of instruction execution, respectively. Trap indicator logic (122 Fig 4) is associated with each ARBSLOT for recognizing an architecturally incorrect execution of a memory instruction and for associating a nonarchitectural panic trap indicator (102) with the instruction after execution. After an instruction is executed in either the AQUEUE (38a) or the MQUEUE (38b), it is retired by the retire mechanism (52). During the retirement process, upon recognizing the panic trap indicator, a trap vector generator (114) purges instructions from the AQUEUE and the MQUEUE and causes the IFETCH to recommence fetching, beginning with a new instruction address to remedy the panic trap event. Additionally, the panic trap system can be used by the IFETCH and the system interface control (108) for timing and synchronization reasons, and it can be used by the DCACHE to recover from parity errors.

Title: Domestic hot and cold water supply
Inventor: DAMPIER RAYMOND GEORGE ALAN
IPC: F24D19/10
Filed: 1997-03-03
Abstract: A domestic hot and cold water supply has 2 pumps 11, 41 controlled by flow switches 17, 27. When a cold water outlet 23 such as a mixer shower or cold water tap is opened, flow switch 17 senses water flow and actuates the pump 11 to boost the mains pressure. When a hot water tap 33 or mixer shower is turned on, flow switch 17 actuates pump 11 as before and in addition flow switch 27 senses water flow and starts up pump 41. This circulates primary water from a hot water store 35 though a heat exchanger 31 to heat the water flowing to the hot tap. The temperature of the secondary water may be controlled by regulating the flow of the primary water through the heat exchanger in response to a temperature sensor. This may be done by throttling the flow, bypassing some of the flow, or varying the speed of the pump.

Title: Track seeking apparatus
Inventor: KO SEONG-RO
IPC: G11B21/10
Filed: 1997-07-16
Abstract: A real-time track seek apparatus and a method therefor are provided by directly gaining access to tracks without passing through a peripheral microcomputer or an interface apparatus when track information is reproduced. The real-time track seek apparatus includes a track information reader and control unit having a track number register, a comparator, a start mark signal detector 22, an ID register, a counter, a cyclic redundancy check code checker. The track information reader and control unit 27 compares the current track number with the target track number to determine a movement direction and the number of tracks and to accordingly make a pickup device move. Here, if a start mark and an ID mark are recognized from reproduced data, the track information reader and control unit 27 reads a track number following the recognized result and judges whether the read result is accurate. If the track number is accurate, the current track number is compared with the target track number to judge whether both are identical to each other. Accordingly, the pickup device is made to continuously move or stop, which provides an effect of reducing a track seek time and stand-by time.

Title: Space heaters
Inventor: NAUGHTON MARTIN LAWRENCE
IPC: F24H3/00
Filed: 1997-07-11
Abstract: A new space heater is disclosed. A casing (12) contains a heat source (1) and includes openings (16,17) which allow the convection of air through the casing (12). The heat source (1) comprises a pair of panels (2, 3) defining between them a closed oil-filled compartment in which an electrical heating element is retained. The openings in the casing (12) allow radiant heat from the heat source (1) to escape from the casing. Because the heat source (1) is contained within the casing (12), it may be heated to very high temperatures. To accommodate the oil expansion, the oil only partially fills the compartment in the heat source and the compartment is subdivided into a lower liquid chamber (8), which at room temperature contains oil, and an enlarged upper expansion chamber (7) which at room temperature contains no oil.
