Date Jul. 11, 1996A baby pacifier includes an actual nipple part and a shield. The actual nipple part includes a piece made of elastic or resilient material that is adapted to be held in the baby's mouth at a location between the middle section of the palate and the tongue, and on which piece the baby exerts suction by movements of the jaws and the tongue. The actual nipple part is shaped so that a vertical cross-sectional profile, viewed in a vertical cross-sectional plane of the buccal cavity, is elongated with protrusions directed from the a middle part of the vertical cross-sectional profile to both sides extending to the alveolar ridges and/or the teeth of the baby's upper jaw. The protrusions are shaped so as to create from the baby's sucking motion principally lateral outward pressure on the inside of the alveolar ridges and deciduous teeth of the baby when the actual nipple part is held in a baby's mouth. The vertical cross-sectional profile of the actual nipple part is slightly V-shaped or the upper edge of the cross-sectional profile has a downwards curvature so that the actual nipple part exerts essentially no pressure on the middle section of the palate.

Inventor: JANSSEN ROBERT ALLEN
IPC: B05C3/109
Filed: 1997-04-18
Abstract: An apparatus and method for uniformly contacting an article with a treatment solution. Preferred embodiments are methods of uniformly tinting of contact lenses or uniformly surface modifying contact lenses. The method involves suspending the lens in the treatment solution by application of fluid flow, preferably sinusoidal or pulsed, in a direction opposite the stagnant force (i.e., sum of buoyancy and gravity forces) on the article. The fluid flow prevents the lens from contacting the container structure for periods sufficient to cause non-uniform treatment conditions, while continuously mixing the treatment solution to maintain uniform concentrations throughout.

Abstract: The invention relates to a process for the bleaching of chemical pulp and the use of a bleaching solution. According to the invention the pulp is treated in a plurality of different steps by using at least in one step a bleaching solution which contains a peracid, and the essential idea of the invention is that the peracid is used in a post-bleaching which is the last step of the bleaching process, the post-bleaching being carried out in the presence of one or more earth-alkali metal compounds. By using a peracid the pulp is brought to its final brightness, and the purpose of the earth-alkali metal added is to combat the lowering of the viscosity of the pulp. According to the invention the post-bleaching can be carried out after the bleach plant steps in a pulp flow pipe, a storage tower or in the paper machine at a paper mill.

Title: Improvements in and relating to process of preparing a cortin-like product
IPC: A61K31/573
Filed: 1958-01-13
Abstract: A process for preparing a cortin-like product is characterized in that the milk or mamma and teat from a mammal, particularly the cow, is extracted at lower than room temperature, preferably between - 5 DEG  C. and + 2 DEG  C., by a solvent of steroids which is miscible with water, and the extract is purified.  Specified solvents are acetone, ethyl acetate, chloroform, methyl alcohol, ethyl alcohol and mixtures of ethyl alcohol and acetone, and ethyl acetate and chloroform.  The extraction is preferably effected after acidification to a pH of 4.5-5 with mineral or organic acid, such as hydrochloric acid or acetic acid, and after agitation of starting material with solvent the mixture is preferably left at lower than room temperature before separating the extract.  The residue of the extraction may be hydrolysed in an aqueous acid medium and the aqueous hydrolysis product further extracted, the extract obtained being added to the main extract. Purification of the extract is effected by means of successive evaporations and extractions, each evaporation being preceded by filtration and the successive evaporations and extractions are continued until an insoluble residue is no longer obtained.  An example describes the preparation of an extract from whole milk in the form of an aqueous solution containing 15% ethyl alcohol which is suitable for administration orally or by injection.

Abstract: 674,115. Sterilizing milk &c. CHERRYBURRELL CORPORATION. Feb. 12, 1948 [Feb. 24, 1947], No. 1485/51. Divided out of 674,032. Class 49. [Also in Group XIII] For sterilizing milk and other liquid foods there is employed the apparatus of Fig. 20 in which a group of spaced heat exchanging plates 42 is divided by terminal frames 164, 264 into three sections, viz. a heating section H, a cooling section C, and a regenerative section R, the space between two adjacent plates being bounded by marginal gaskets on the plates 42. Milk to be treated is drawn by vacuum created by the pump 115, from the supply tank 112 through the pipe 113, to the terminal frame 264 from whence it passes through alternate spaces between the plates of the regenerative section R to the outlet conduit of the terminal frame 164, through the pipe 114 to the pump and then to the inlet of the terminal frame 164 after which it passes through the heating section H and through the pipe 117 to a thermostatically controlled flow diversion valve 118. If at the correct temperature the milk is then directed by the valve 118 through the conduit 120, to the terminal frame 164 and through the regenerative section R where it is cooled by heat exchange with the inflowing milk from the tank 112 and then to the terminal frame 264. The milk flows from the terminal frame 264 through the cooling section C to the compression element 80 from which it is discharged through the conduit 121. If the milk has not attained the correct temperature when it reaches the flow diversion valve 118 after passing through the regenerative and heating sections of the apparatus, the valve operates to divert the flow through the pipe 123 and back to the supply tank 112. Cooling water for the cooling section C is supplied from the main to the inlet conduit 202 of the compression element 80.from which it flows through the plates of that section in heat exchange with the milk passing therethrough to the terminal frame 264 and back through the cooling section to the element 80 from which it is discharged through the conduit 203. Hot water for the heating section H is supplied to the lower end of the standard 1 from a water heater W and circulates through alternate spaces between the plates of that section to the terminal frame 164 from which it is returned to the upper end of the standard 1 and thence through the pipe 201 to the heater W.

Title: Improvements in or relating to means for feeding glass to glass shaping machines
IPC: C03B7/18
Filed: 1935-01-18
Abstract: 434,639. Glass manufacture. UNITED GLASS BOTTLE MANUFACTURERS, Ltd., and MOORSHEAD, T. C., 40, Norfolk Street, Strand, London. Jan. 18, 1935, No. 1776. [Class 56] A device for feeding charges of glass to the moulds of a forming-machine, particularly the machine described in Specification 281,383, [Class 56], comprises a rotatable unit driven from the forming machine and having a number of radial arms, each arm being provided with a suction cup which gathers charges of molten glass from a forehearth and discharges them into the moulds. The gathering cups 10 are rotated, either continuously or intermittently, about a stationary vertical column 1, the various movements of the gathering cups and of other mechanism being controlled by stationary cams 14, 18, 20 secured to the column 1. The cam 14 raises and lowers the cups so that each cup, as it passes over the forehearth, is dipped into the molten glass 2 to gather a charge. The cam 20 operates valves 46 which control the application of suction to draw the molten glass into the cups. The cam 18 operates a valve 67, arranged in the head of each of the cups, which admits compressed air to the upper part of the cup. A cut-off knife 75 is carried by an arm 76 pivoted to a suitable part of the machine, and the knife is normally held in the position shown by means of a spring. A cam 79, secured to the arm 76, lies in the path of studs 84 which are secured to the rotating framework. Means are provided for adjusting the position of the height of the knife to suit the gathering cups, and means are also provided for enabling the vertical position of the machine as a whole. In operation, as each cup approaches the gathering-position it is dipped into the glass 2 and gathers a charge. As the filled cup rises from the glass, a stud 84 strikes the cam 79 and swings the shear blade backwards. When the stud moves off the cam, the blade is swung by its spring across the bottom of the cup and cuts off the trailing glass. When the cup approaches a mould 4 of the forming-machine, the valve 46 is closed to stop the application of suction and the valve 67 is operated to admit compressed air to the cup. This serves to eject the charge of glass from the cup, the operation being so timed that the charge falls at the mould 4.
