Filed: 1990-01-23
Abstract: The invention relates to a toothpaste which contains a mixture of an alkalimetal trimetaphosphate and a fluoride salt as anti-caries agents. The interaction between the trimetaphosphate salt and the fluoride salt is substantially reduced by providing the trimetaphosphate salt to be present in the liquid phase of the toothpaste in at least partly insoluble form. Optimum results are obtained if all the trimetaphosphate is present in insoluble form in the liquid phase.

Abstract: In a speech recognition system where a speech analyzer analyzes an input speech to produce an input speech pattern which is memorized in an input memory as a memorized input pattern, a pattern comparator comparing the memorized input pattern with reference patterns previously memorized in a reference pattern memory and producing pattern dissimilarities between them, and a speech deciding circuit  deciding  the  minimum  one  of  the  pattern dissimilarities to thereby recognize the input speech, a word is twice uttered to produce a first and a second speech during a registration mode in order to correctly register a speech pattern of the word into the reference pattern memory.   Speech patterns of the first and the second speeches are memorized into the reference pattern memory and the  input memory as a first and a  second memorized pattern, respectively, which are compared with each other at the pattern comparator to produce a pattern dissimilarity.     A  registration  deciding  circuit  is selectively coupled to the pattern comparator during the registration mode and decides whether or not the pattern dissimilarity is larger than a predetermined reject value and permits one of the first and the second memorized patterns to be registered as a reference pattern into the reference pattern memory when the pattern dissimilarity is not larger than the reject value.

Filed: 1991-06-05
Abstract: Abstract The pipe coupling having an elastomer sealing sleeve which is approximately C-shaped in cross-section has a cylindrical housing which is split in the longi-tudinal direction, has end walls bent inwards and can be constricted like a pipe clip by means of a closure having tensioning screws, in which arrangement the sleeve, which is enclosed at the end faces and at the circumference by the housing and by a metal insert sheet bridging the housing gap and is  approximately C-shaped in cross-section, is compressed in the circumferential direction and is brought to bear against the pipes to be coupled. Sliding rings compressible in the circumferential direc-tion are located between the end faces of the sleeve and the end walls of the housing, which sliding rings, upon assembly of the coupling, are brought to bear against the outer walls of the pipes and form a sliding seat with the latter. This leads to the increase in insensitivity to changes with regard to the relative position of the sealing parts and the parts to be sealed, the existing adaptability of the coupling to irregular pipes at the same time being further increased.

Title: Back-up safety device and method
Inventor: MIELE JOSEPH R
IPC: B60T7/22
Filed: 1990-04-18
Abstract: The device senses the impact of a vehicle (10) backing into an object; and automatically applies the brakes of an ordinary hydraulic brake system to stop the vehicle very quickly, before any significant damage can be clone. The device uses a pneumatic cylinder (24) to quickly and powerfully pull on the brake pedal (16) of the vehicle when the vehicle is in reverse gear and an im-pact is sensed. A small, light-weight and relatively inexpensive air compressor (18) which runs off of the battery (32), of the vehi-cle and a reservoir (20) are used to supply the air cylinder. The brakes stay in the actuated condition until the vehicle is taken out of reverse gear (38); then the air cylinder is vented to atmosphere automatically, and the brake pedal is released to return it to its initial position and enable the normal operation of the vehicle. The device can be supplied in the form of a kit to be used to easily modify existing vehicles without invading the hydraulic brake lines or vacuum system of the vehicle.
