Patent GB-2261807-A (GB)
Title: Thawing frozen food
Inventor: MILES CHRISTOPHER ANTHONY
IPC: A23L3/30
Filed: 1992-11-04
Abstract: A method of thawing frozen food characterized by directing ultrasonic energy into frozen food subject to the conditions that (a) the frequency is high enough that the energy is not attenuated excessively at the surface of the food, and (b) the frequency is low enough that the energy is not attenuated excessively in the body of the thawed food, whereby the energy effecting the thawing results primarily from the absorption of the ultrasonic energy in the zone between any thawed portion and the substantially frozen portion, the thawing zone. A further condition may be that the cavitation threshold is increased for example by increasing the ambient pressure.

Title: Cardholder alarm system
Inventor: HIRSHBERG ISRAEL
IPC: G08B21/24
Filed: 1992-11-10
Abstract: The system is used to remind a credit card owner to collect his card after he handed it for making payment. After a predetermined period of time the device will sound voices so as to attract the card owner to the absence of his card. Collecting the card and putting it back into its storage place will stop the voices, thus preventing the forgetting of the card after it was used. The device comprises a voice programmable chip 5 connected to a tiny loudspeaker 4 and a switch 8, 9 which is operated when the credit card 1 is removed from its place thus closing an electrical circuit which triggers a timer to count a predetermined number of seconds after which the voice chip is actuated to produce voice to attract the owner's attention to his credit card. The voice can be of any kind such as: human voice words, or a melody.   <IMAGE>

Title: Transaction card verification system
Inventor: GOLD MALCOLM
IPC: G07F7/10
Filed: 1993-04-03
Abstract: A transaction card verification system comprises a card scanning unit 6 and an identification code input unit 2 and means for connecting the system to a remote computer. In operation the scanning unit is used by a first user, such as a user offering goods for sale and the identification input unit is used by a second user such as a prospective purchaser of the goods. The second user inputs an identification code which is checked against a code associated with the details of the card in a remote computer and a transaction verification signal issued when the codes match. Conflicting codes stop the transaction proceeding. <IMAGE>

Title: A method and arrangement for use in the elimination of echoes in a subscriber line circuit
Inventor: LOEFMARK BENGT GUSTAV
IPC: H04B3/23
Filed: 1993-04-15
Abstract: The invention relates to echo elimination in a subscriber line circuit having digital signal processing. Echo elimination is effected with the aid of a digital balance filter (17) which is connected in an interface where the clock frequency, e.g. 16 kHz, is higher than the original sampling frequency, e.g. 8 kHz, of transmitted signals. The requisite size of the balance filter can be reduced by clocking the filter at the same frequency, e.g. 8 kHz, as the original sampling frequency of the transmitted signals.

Title: Manufacture of bonded friction elements
Inventor: BALDWIN DOUGLAS
IPC: F16D69/00
Filed: 1994-05-11
Abstract: A brake shoe in which a friction lining 16 is secured to a platform 12 of a shoe body 11 solely by a thermosetting adhesive resin 20 cured at elevated temperature is manufactured by using a friction material including fibrous reinforcement materials and an uncured thermosetting hinder, roll formed to define a green lining element which is sandwiched with the adhesive between the platform and a bearing surface that applies small constraining pressure (e.g. 0.1 - 0.34 MPa) by way of the major faces 17, 18 but not minor faces 19.

Patent GB-2305736-A (GB)
Title: Method of aligning micropatterns on semiconductors
Inventor: BAE SANG MAN
IPC: G03F9/00
Filed: 1996-09-27
Abstract: A method for aligning micro patterns of a semiconductor device, capable of reducing the number of dies having poor quality in the formation of patterns in device. The method utilizes the fact that even in the case of a semiconductor wafer having alignment marks damaged due to an error occurring in the formation or etching of thin films, outer mark portions of its overlay measuring marks can be observed. For several dies sampled as observation dies from the semiconductor wafer, light exposure is carried out to form photoresist film patterns under the condition that the semiconductor wafer is misaligned from the light exposure mask. Thereafter, alignment marks and inner mark portions of overlay measuring marks are formed. A misalignment angle * small Greek theta * between the semiconductor wafer and light exposure mask is also calculated. In the stepper, the degree of misalignment is then corrected based on the result of the calculation. In this state, subsequent processes are conducted for normal dies other than the observation dies. Accordingly, it is possible to reduce the number of dies which are considered as having a poor quality, thereby achieving an improvement in operation reliability of the semiconductor device.

Title: Compensating for defective memory associated with a decoder
Inventor: CHEN CHIH-HSIEN
IPC: G11C29/00
Filed: 1997-04-11
Abstract: A method of compensating for defective memory associated with a decoder is provided. This method checks initially the memory if any of the blocks therein is defective. If defective blocks are detected, the block numbers thereof are recorded in a set of registers. When data are to be written into the memory, a series of requested block numbers are issued, which are compared to the block numbers of the defective blocks recorded in the registers. Implemented by a defective-block skipping circuit, the series of requested block numbers is converted into a new series of block numbers in which the defective block numbers are excluded. As a result, the defective blocks in the memory will not be selected for storage of the data. The method may be used in a CD player.

Title: Intermittently moving belt filter
Inventor: MILLER PETER ANTHONY
IPC: B01D37/03
Filed: 1997-05-08
Abstract: In a gas pressurised, intermittently moving belt filter, a section of filter belt is supported on a perforated plate and sealed between a cover and a receptacle. Liquid to be filtered and pressurised gas are supplied above the filter belt, and filtrate is removed from below the filter belt. After filtration, rams (201) lift the cover away from the receptacle and the section of belt is moved out of the filter chamber by means of reversing motor 126. Flocculants and granular material may be added to form an electrically charged filter bed on top of the belt. Alternatively, lengths of disposable filter medium cut from rolls 112 may be laid on top of the belt. The belt may have portions (501, 502, 503) of different materials. The belt may be cleaned by passing it through a bath (901). The inside of the filter chamber may be cleaned by rotating manifolds (125) or by nozzles 710 on a travelling manifold 711. The wash liquid, the gas, and the granular filter material are all recycled. The cover may be in two parts (713, 705). All operations are controlled by a computer 124.
