Title: Sol-gel composition containing hydrolysable silicic ester for producing glassy coatings
Inventor: PATEL BIPIN CHANDRA MULJIBHAI
IPC: A61K6/896
Filed: 1992-07-08
Abstract: Glassy coatings are made by curing in situ a coating of a sol gel, xerogel or heat-consolidated gel composition comprising a hydrolysable silicic ester, a solvent, and alkoxides of a Group IA metal and of one metal selected from Al, Zr and a Group V B metal. The metal alkoxides are preferably the following combinations:- i) Al, Ti, Na; ii) Zr, Na. The composition may also contain a filler, e.g. talc, mica, laponite, zeolite, kaolinite or vermiculite, which may be coated with titanium dioxide, chromium oxide or ferric oxide. The solvent may be a ketone or alcohol. The composition may be cured to form the glassy coating by the use of laser radiation or a butane gas flame. Use is made of very miniature flames so as to avoid vital tissue when curing on a tooth in situ. Part of the silicic ester may be replaced with other glass formers such as a boron-based sol gels. The coating may be applied to teeth as a dental fissure sealant or varnish to protect restorations, or (if filled) as an inherently coloured cosmetic coating, or as a prophylactic coating. In an application for slow drug release the coating may be charged with a drug, eg for treating dentine hypersensitivity or peridontal disease.

Title: Method of recording compressed digital audio data by removing redundant bits
Inventor: AKAGIRI KENZO
IPC: G11B20/10
Filed: 1992-07-31
Abstract: Compressed audio digital data is recorded on a medium such as an IC card 2. The signal to be recorded is derived by an excess bit reduction circuit 84 which removes redundant bits (which make no difference to quantization noise perceived by the human ear) from the compressed digital data, resulting in a recording signal of variable bit rate. The technique is suitable for high-speed copying in which compressed audio digital data is reproduced at a constant bit rate from one medium such as a magneto-optical disc 1,the reproduced data is bit reduced, and the bit-reduced data is recorded on another medium such as the IC card 2 at a variable bit rate. <IMAGE>

Title: Dispensing fluids from containers
Inventor: DAY ARTHUR HAMBROSE
IPC: F17C9/02
Filed: 1993-04-21
Abstract: Liquid nitrogen contained in an insulated vessel (12) is dispensed in gaseous and/or liquid form via an outlet pipe (50, 51). A sample of gas is taken from the headspace (30) and pumped through a closed loop (32) outside the container. The sample takes up heat in the loop and is re-introduced via an inlet (36) so as to impinge on the liquid surface (28), thus heating a surface layer and increasing the pressure in the container whereby fluid can be dispensed. In a modification the warmed gas sample is bubbled through the liquid pool (26) so as to heat a localised column of liquid. The invention is applicable to the controlled dispensing of fluids stored cryogenically. <IMAGE>

Title: Flexible latch
Inventor: MANSER GEORGE ANTHONY
IPC: E05C1/06
Filed: 1993-06-24
Abstract: A flexible latch has a cable pull, with inner and outer cables, one end has a pull handle connected to the inner cable. The cable pull assembly is connected to a latch assembly that has a body with a sliding bolt, end stop and spring. The body has a slot that allows a grub screw, that is connected to the bolt, and pinches the inner cable, thus completing the assembly and allowing the bolt to move a specific distance longditudinal, and stops a radial movement. When a pull force is applied to the handle, the force is transmitted to the latch bolt thus opening the latch or the particular application it is fixed to. This inventive step thus allows for a pull force in one place to be transmitted to another place where it does the work. <IMAGE>

Title: Controlling the speed of a vacuum cleaner motor in dependence on the degree of soiling of the treated surface
Inventor: DORSCH DIETER
IPC: A47L9/00
Filed: 1994-08-25
Abstract: A housing (1) conducting the airstream (9) containing the intaken particles is provided with an angle-including entry conduit (4) and exit conduit (5) and with a baffle plate (6) between them to deflect the particle flow. A measuring microphone (20, 21) serves to detect the noise generated by the rebounding particles. A compensation microphone (20) is coupled to the housing (1) to deliver a noise signal as data in respect of the noise from the equipment in order to blank the same out of the microphone signal. By means of an electronic circuit arrangement the microphone signals delivered by the measuring microphone (20, 21) are converted to control signals to control the speed of the fan motor (M). In this way the general noise level which would otherwise be much too high due to improper operation, can be greatly reduced. <IMAGE>

Title: Measuring dielectric properties of materials
Inventor: CHAN TSING YEE AMY
IPC: G01R27/26
Filed: 1995-02-28
Abstract: A probe (1) is used to measure the dielectric properties of rigid or semi-rigid materials (4), for example, works of art. The probe comprises an inner conductor and an outer, coaxial, conductor separated by a layer of insulator e.g. Teflon (TM). The probe is coupled to a network analyser (11), which provides microwave frequency radiation which is transmitted by the probe on to the surface of the material where it is reflected back from the surface back down the probe to the analyser, where it is analysed to give measurements on the dielectric properties of the material. The probe typically has an outside diameter of around 0.86 mm, and because of its size allows measurements to be made, non-invasively, and in real time on small areas of material. The outside diameter can be made of the order of microns by selecting the frequency of the radiation, which allows measurements to be made in a sample of a semi-rigid material e.g. a layer of paint for depth profiling. The probe has particular application in the measuring of works of art. <IMAGE>

Title: Sampling circuit with phase correction for digitalizing colour signals
Inventor: INADA YOSHIHIRO
IPC: H04N9/44
Filed: 1995-03-28
Abstract: A sampling circuit includes a phase difference detecting circuit 5 which detects a deviation of a sampling clock (d 2), equal to a multiple (eg 4) of the colour video signal carrier frequency, from optimal sampling timing and outputs a phase difference signal (EQU, UPDN) in response to three differently delayed digitalized colour video signals (DA, DB, DC) derived from phase reference detecting circuit 4 and A/D convertor 1. A phase reference signal (ORG) which is used as a reference to determine a phase advance and a phase lag is also generated by a phase reference detecting circuit 4 in response to the colour burst signal component of the video input signal. In accordance with these signals, a sampling clock shifting circuit 2 shifts the phase of the sampling clock (d 1) so that the sampling clock (d 2) is activated at optimal sampling timing. Sampling is performed in accordance with such a sampling clock (d 2), whereby a basic signal is generated from which the phase reference signal (ORG) and the phase difference signal (i.e., an equivalent signal (EQU) and a non-equivalent signal (UPDN)) are generated. By means of the feedback control, the sampling clock is automatically activated at optimal sampling timing. <IMAGE>
