Title: Digital-analogue converter circuit for speech-synthesizing electronic timepiece
IPC: G10L19/00
Filed: 1981-02-26
Granted: 1984-05-10
Abstract: A novel type of digital-to-analog converter circuit is disclosed for an electronic timepiece having a speech synthesizing capability. The converter circuit utilizes pulse width modulation to form a train of pulses in response to successive digital signals which specify amplitude and polarity values for synthesizing speech, with the pulse widths being determined in accordance with the digital signal values. By filtering out the unwanted high frequency components of this pulse train, speech signals can be synthesized through an audio transducer. Such a digital-to-analog converter is capable of operating in a satisfactory manner at low levels of supply voltage, and has a very low power consumption.

Title: A beverage package and a method of packaging a beverage containing gas in solution
Inventor: FORAGE ALAN JAMES
IPC: B65B3/04
Filed: 1985-11-29
Granted: 1989-10-04
Abstract: A beverage package and a method of packaging a beverage having gas (preferably at least one of carbon dioxide and inert (nitrogen) gases) in solution has a non-­resealable container l within which is located a hollow pod 4 having a restricted aperture 7 in a side wall. The container is charged with the beverage 8 and sealed. Beverage from the main chamber of the container enters the pod 4 (shown at 8a) by way of the aperture 7 to provide headspaces la in the container and 4a in the pod 4. Gas within the headspaces la and 4a is at greater than atmospheric pressure. Preferably the beverage is drawn into the hollow pod by subjecting the package to a heating and cooling cycle. Upon opening the container l by draw ring/region l3, the headspace la is vented to atmosphere and the pressure differential resulting from the pressure in the pod headspace 4a causes gas/beverage to be ejected from the pod (by way of the aperture 7) into the beverage 8. Said ejection causes gas to be evolved from solution in the beverage in the main container chamber to form a head of froth on the beverage. The pod 4 is preferably formed by blow moulding and located as a press fit within the container l which latter is preferably a can, carton or bottle.

Title: Prepayment systems
Inventor: GOLIGHTLY DEREK
IPC: G07F7/08
Filed: 1992-09-28
Granted: 1995-01-18
Abstract: A prepayment commodity metering system comprises a token in the form of a key containing an EEPROM which a consumer can have charged with credit data, identification data and tariff data by the commodity supplier, and which is then inserted into a prepayment commodity meter at the consumer's premises to give the consumer access to the commodity. The meter can also write data, particularly its reading or readings and related time and date data, into the EEPROM, for reading by the commodity supplier on the next occasion the token is presented for charging with credit. To improve the integrity of the data in the EEPROM, the EEPROM is divided into two parts. A given contact or pin on the key is then arranged, when the key is inserted in the meter, to receive an inhibit signal which prevents data being written to any part of the EEPROM other than the part dedicated to receiving the meter reading or readings and the related time and date data from the meter.

Title: Carbonyl sulphide fumigant and method of fumigation
Inventor: BANKS HENRY JONATHAN
IPC: A01N31/02
Filed: 1993-01-15
Abstract: The gaseous chemical compound, carbonyl sulphide, has hitherto been unknown as a fumigant for the control of insects and mites. Experiments have shown conclusively that carbonyl sulphide can be used as such a fumigant, with fumigation properties comparable to those of phosphine and methyl bromide. The effectiveness of carbonyl sulphide against insects (both adult and immature stages), mites, termites and moulds is demonstrated. In addition, its low absorbtion by grain, lower flammability than phosphine, lack of influence on seed germination, and apparent environmental safety make carbonyl sulphide particularly beneficial as a fumigant of stored grain. It may also be used to fumigate other stored produce (including perishable foodstuff), soil, timber and spaces (such as buildings) and any material likely to be infested by insects or mites, or act as a source of such infestation.

Title: Procedure for the automatic welding of metal pipes
IPC: B23K/
Filed: 1989-12-07
Granted: 1993-02-02
Abstract: Procedure for the completely automatic flame welding of metal pipes, particularly for home refrigerators.The said metal pipes may be made of different materials or alloys. The procedure for their automatic welding is based on automatic recognition, by position sensors, of the position of the pipe to be welded, and a successive flame welding phase of the thus identified tubes.The welding occurs by use of a special solder, composed of silver and a core of a deoxidizing substance.In this way, different metals can be welded with the same quantity of solder, and with the same procedure, and without the need for a preliminary phase of deoxidation of the weld area.The procedure is formed by an ordered sequence for the activation of the different recognition phases of the weld head and solder positioning, and in which the single individual phases are coordinated in time and in position, by a single command control system within the sequence.
