Title: Analogue to digital converter
Inventor: BLYTHE JOHN HOSKING
IPC: H03M1/00
Filed: 1986-10-18
Abstract: Apparatus for converting an analogue signal 1 to digital form includes an A/D convertor 4 having insufficient digits for the accuracy required, a prediction circuit 5 providing a prediction 8 of the input signal based on previous cycles, and means 2 for calculating an error signal from the input signal 1 and the prediction 8 and feeding the error signal to the A/D convertor 4. An output of improved accuracy is obtained by adding, 11, the error signal from the A/D convertor 4 to the prediction 8 to generate an output. The prediction circuit 5 may include a second adder receiving the outputs of delay 7 and a delay connected to the output of adder 11, the output of this second adder being supplied to a rounding circuit which feeds the adder 11 and D/A converter 9. <IMAGE>

Title: Microprocessor emulation
Inventor: MACGREGOR RODERICK
IPC: G06F9/44
Filed: 1987-03-24
Abstract: Data processing means adapted to be controlled by sequential instructions, a substantial number of which comprise an operation code selected from a set of n such codes and a qualifying code selected from a set of m such codes, comprises a store having approximately n times m locations with each location corresponding to a consistent combination of operating code and qualifying code and holding a series of instructions corresponding to the said operating code and qualifying code. The qualifying code may be the addressing mode and a jump table 18 of 256 x 256 entries may be employed to access the instruction series. The use of both codes to access the jump table enables code strings of a host processor (e.g. 68020) to be accessed quickly by the op-code and immediately succeeding byte in an instruction of a processor (e.g. 8088) being emulated and avoids the need for routines to analyse the addressing mode. <IMAGE>

Title: Hot water containers; self- priming of primary water system
Inventor: HANSON-GRAVILLE GEORGE
IPC: F24D19/08
Filed: 1987-09-17
Abstract: In a hot water container 1 comprising a heat exchanger 3a capable of connection to a primary water heating system, self priming means for the primary system is located within the principal container interior. A pair of communicating upper and lower chambers 9, 10 are capable of receiving or transferring water and/or air, the two chambers communicating through a first duct 12. A second duct 16 extends from or near the bottom of the upper chamber to communicate to atmosphere 18 and provide a hot water draw-off 17. The lower chamber 10 is capable of connection to both a primary heating circuit and an external auto-vent 25. The upper chamber 9 is in communication via a third duct 15 with the main body of the container 1. Separation of potentially contaminated primary heated water from a secondary hot water supply may be maintained by air pocket(s) within the chambers and a sealed partition if required. Water replenishment may be automatic and boiling malfunction is particularly catered for.   <IMAGE>
Patent GB-878297-A (GB)
Abstract: 878,297. Automatic temperature-control systems for heating resistors. MINNEAPOLISHONEYWELL REGULATOR CO. Dec. 30, 1957 [Dec. 28, 1956], No. 40353/57. Class 38 (4). In an automatic temperature control system for a fluid-filled gyroscope, the working temperature of the gyroscope is maintained above the ambient temperature by external heating coils. When the ambient temperature at warmup is below a predetermined value, a warm-up heater 30 is connected in place of a regular heater 28. When a switch 116 is closed a heater 76 of a thermal delay switch 74 is energized and a contact 71 of a relay 68, controlled through an amplifier 56, is closed due to the unbalance of a bridge 36 to energize a relay 90 which through a contact 96 closes the circuit of the warm-up heater, by a contact 94 shortcircuits a contact 79 of the thermal delay switch 74 and by a contact 98 isolates the regular heater 28. The bridge 34 has in one arm a thermal resistor 40 sensing the gyroscope internal temperature and shunted in an adjacent arm a thermal resistor 46 sensing the ambient temperature and arranged so that the internal temperature at which the bridge balances increases with reduction in ambient temperature. At balance, the relay 68 is de-energized and contact 71 opened to de-energize the relay 90, a contact 100 of which short-circuits the thermal resistor 46 so that the bridge will rebalance at the working temperature and control the regular heater 28 by the relay 68. The relay 90 is isolated by the contact 79 of the thermal delay switch 74. During warm-up, if the ambient temperature is above a predetermined value, a thermostat 84 isolates relay 90 and the gyroscope is brought up to working temperature by the regular heater.

Patent GB-2227112-A (GB)
Title: Printer with improved data entry
Inventor: FIDLER THOMAS DEAN
IPC: B41J29/40
Filed: 1990-01-04
Abstract: In a printer, a predetermined set up time is established for entering semi-fixed information, that is, information which changes but relatively infrequently. Semi-fixed information is entered from a limited keyboard (96) only once after the printer is powered-up, into a non-volatile RAM (94) which also holds fixed information. A bit map image of the NVRAM (94) contents is created once in a static RAM (60). Thus only a bit map image of variable information need be created each time the printer is operated to print. In one mode of operation, the printer's processor (54) is responsive to the actuation of keys to control a display (82) and the entry of data for printing. In a second mode of operation, however the printer's processor is responsive to the actuation of the same keys to control the movement of paper stock with respect to a print head (50). Data entry uses keyed selection from wrap-around scrolled displayed lists.

Title: Sorting particles of differing thermal conductivities
Inventor: ASHBY KEVIN PETER
IPC: B07B13/00
Filed: 1990-02-20
Abstract: The particles are wetted with a liquid such as water, and the wetted particles brought into contact with a surface (14) which is at a temperature at or below the freezing point of the liquid. After a specified time period, particles which do and which do not adhere to the surface as a result of freezing effects are separately recovered from the surface, for example in bins (24, 26) separated by a divider (28). The method is particularly useful for separating diamondiferous from non-diamondiferous particles. <IMAGE>

Abstract: In a mechanism for controlling the travel of a structural member, such as a drawer 2 slidably mounted within a cabinet 1, the drawer 2 is formed with a pair of sliding rails 4, 4 which engage a pair of fixed rails 3, 3 on the cabinet 1. A traveller device 6 is fixed to each of the sliding rails 4, 4 and comprises a coil spring mechanism 7 for automatically closing the drawer 2. To restrict the speed of closure a roller mechanism 18 inside the traveller device provides friction as the drawer 2 is closed. Further, the shaft of the larger roller rotates in a highly viscous oil to increase the drag on the drawer 2. A lock plate 9 is pivotted to each traveller device 6, 6 and is operable on opening the drawer once the traveller device 6 hits a stopper 35. The lock plate 9 locks the traveller 6 device to the fixed rail 3 and disengages it from the drawer 2. <IMAGE>
