Title: Phonograph for selectively producing various sounds
Inventor: OGIWARA MASARU
IPC: G11B19/02
Filed: 1990-11-13
Abstract: Various sounds are produced by an acoustic phonograph for use eg; in a doll, a telephone toy, or other toy by setting an acoustic pickup 60 in a selected one of several grooves in a disk 21. A speaker cone 71 receives vibrations from the pick-up stylus 60 and directly produces a sound wave. A single push-up rod 73, controlled by a selected push-up rod controlling member Q1-Q6, pushes the speaker cone 71 away from the stylus 60 until the pick-up stylus 60 is in position above the selected groove on the recording disc by means of a tilting member (90) which is subsequently released by a projection (24 Fig 5) on the turntable as it rotates. <IMAGE>

Title: Digital storage of analogue optical signal
Inventor: O'DONNELL ADRIAN CHARLES
IPC: G11C7/16
Filed: 1991-09-13
Abstract: An optical signal of high bandwidth on line L is divided into a plurality of signals each of narrower bandwidth by a matrix array of optical switches DMXM. Optical to electronic converters OE convert each of the plurality of optical signals into electronic signals, and analogue-to-digital converters AD convert the electronic signals into digital signals. Digital memory DM stores the digital signals. A corresponding arrangement of digital-to-analogue converters DA, electronic to optical converters EO and a matrix array of optical switches MXM allows the contents of the memory DM to be read out. The switch may comprise a "tree" of two-way switches driven by oscillators of successively lower frequency (fig 2). Each of the plurality of analogue-to-digital converter means may have a bandwidth less than the bandwidth of the first optical signal so that a signal of higher bandwidth (eg 15 GHz) than would otherwise be possible may be processed. <IMAGE>

Title: Electrochemical cell of lithium-manganese oxide type and method of making
Inventor: THACKERAY MICHAEL MAKEPEACE
IPC: H01M6/16
Filed: 1991-12-18
Abstract: An electrochemical cell precursor comprises a housing having an anode terminal exposed to its interior, an electrolyte is in the housing for electrochemically coupling the terminal to a cathode in the housing, a cathode precursor being in the housing, and comprising at least one compound of lithium, manganese and oxygen, which falls in a defined area of an isothermal slice of the Li-Mn-O phase diagram at 20 DEG C. The cell precursor is made by loading the electrolyte and cathode precursor into the housing, such that the anode is electrochemically coupled by the electrolyte to the cathode precursor, being electrochemically insulated therefrom. The cell and its electrodes are made by subjecting the cell precursor to a charging potential whereby the cathode precursor acts as a cathode and becomes activated by loss of lithium which is deposited to form at least part of the anode. The cathode precursor can be made by heating in a reducing atmosphere a compound of lithium, manganese and oxygen. The method avoids the use of metallic lithium which is dangerous to handle and necessitates inert atmospheres.

Title: Compositions containing plasmin activity inhibitors
Inventor: LOHMANN CHRIS P
IPC: A61K38/57
Filed: 1992-09-04
Abstract: Plasmin activity reducing agents are used to reduce visual refractive regression after occurrence of a wide area superficial ablation wound of the anterior corneal surface of the eye by topical administration to the eye optionally with concurrent administration of an anti-inflammatory drug, preferably a steroid. A screening method is also described for assessing the risk of post-operative visual refractive regression in the eye of a potential patient after occurrence of a wide area superficial ablation wound on the anterior surface of the cornea resulting from the operation. Tear fluid is tested pre-operatively to determine the level of proteolytic agent therein as an indicator of potential post-operative visual regression. Typical plasmin activity reducing agents are aprotinin, alpha -antitrypsin,  alpha -antiplasmin,  alpha -macroglubin, monoclonal antibodies to plasmin or plasminogen activator inhibitor-2.

Title: A multifuctional valve with a thermoelectric safety feature for the gas burners of heating appliances in general
Inventor: TURRIN GIANPIERO
IPC: F23N5/10
Filed: 1993-05-12
Abstract: A multifunctional valve in which the push-button controls (20, 22) for ignition and extinguishing a burner (4) act on switches (19, 21) provided in the energising circuits of the gas-inlet solenoid valve (8) and the thermocouple circuit (17) respectively. Gas entering inlet (2) supplies gas to pilot light (13) and the main burner (4). During ignition, button (20) is pressed so that switch (19) is in the dotted position. This operates solenoid (8) and allows gas to pass to the pilot light. Also the igniter is operated via ignition device (16). When the pilot light is lit, thermocouple (17) activates magnet assembly (18) to keep obturator (6) open. Release of button (20) moves switch (19) so that solenoid (12) is operated so that gas can pass to burner (4). Pressing button (21) deactivates magnet (18) so that obturator (6) closes gas to the pilot light and the burner. <IMAGE>

Title: Splicing narrow strips using two adhesive elements
Inventor: MINARELLI ALESSANDRO
IPC: B31F5/06
Filed: 1994-05-24
Abstract: Two narrow strips of material 2, 3 are spliced by superimposing the strips and placing adhesive elements 45 (preferably circular labels) either side of the strips such that the adhesive elements contact both the respective strips and each other at least at one point. In a machine for forming the splice, the strips of material are mounted on two reels (4, 5; Figure 1); when it is detected that one reel is almost empty, a new strip from the other reel is fed to the splicing unit. The two strips are arrested inside the splicing station 21 and arms 47 are rotated to swing blocks 50, which both hold a circular label by suction, together to apply the labels forming the splice. A pendulum 65 with blade 64 is then activated to cut the end of the strip from the empty reel and the spliced strip is fed from the new reel. <IMAGE>

Title: Control system for an internal combustion engine
Inventor: SCHNAIBEL EBERHARD
IPC: F02D43/00
Filed: 1994-11-30
Abstract: In a drive slip control system, a reduction in the torque generated by the internal combustion engine (10) is achieved by suppression of individual cylinders in accordance with predeterminable suppression patterns or by shifting the instant of ignition or firing angle. The suppression pattern is selected in dependence upon the desired reduction in torque. The suppression of cylinders is permitted only when the number of cylinders suppressed per working cycle in the selected suppression pattern lies above a threshold value. The threshold value depends upon the operating state of the internal combustion engine, particularly upon at least one of the operating parameters temperature of the internal combustion engine, exhaust gas temperature, catalyzer temperature, load, rotational speed or a variable which indicates whether a warming-up function of the internal combustion engine has been activated. <IMAGE>
