Title: Teeth cleaning device
IPC: A46B15/00
Filed: 1979-02-22
Abstract: A teeth cleaning device consists of an elastic sheath 1, Fig. 1 wearable on the index finger with a brushing element formed of bristles 2 or other stiff filaments projecting from it substantially radially e.g. over part of one side. Longer bristles 3 formed into a downward projecting tuft may be located at the tip of the sheath. Foam of plastics material or a coarse felt may replace the bristles over part or all of the brushing element. The sheath may be thickened and/or stiffened where the bristles are attached to improve the retention of the bristles. The sheath may have a constriction to fit over the first joint of the finger so that it is held on the finger more securely. The device may be formed integrally of a suitable plastics material. Different sizes may be stored with a finger gauge, as shown in Fig. 8. <IMAGE>
Patent GB-2018249-A (GB)
Title: Urea synthesis
IPC: C07C239/00
Filed: 1979-03-15
Abstract: Urea is produced form a gaseous mixture of H2, N2 and CO2, e.g. that obtained by the steam reforming of hydrocarbons. Carbon dioxide is absorbed from the mixture by the action, firstly, of an aqueous ammonia solution (e.g. above 70% by weight) and, secondly, of an ammonia-containing solution of ammonium carbonate, a solution of ammonium carbamate thus being obtained, together with a gaseous stream of nitrogen and hydrogen. The carbamate solution is passed to a urea reactor to obtain a urea solution containing unconverted carbamate and excess ammonia. The carbamate is decomposed and the evolved ammonia is recycled to the urea reactor along with carbon dioxide. The urea solution, now containing a reduced amount of carbamate (e.g. 50% of its original content), is passed to an adiabatic stripper in which the stripping gas used comprises hydrogen and nitrogen obtained from the CO2-absorption stage. Decomposition products together with water are removed from the adiabatic stripper, and are condensed in the presence of ammoniacal ammonium carbonate and the condensate so obtained is passed to the CO2-absorption step. <IMAGE>
Patent GB-2021965-A (GB)
Title: Separating liquids
IPC: B01D17/04
Filed: 1979-07-05
Abstract: Coalescence of "secondary dispersion"-sized droplets (under 30 microns) of a first liquid dispersed in a second liquid is effected by feeding the dispersion to a mixing zone containing further first liquid, mixing the dispersion and the first liquid so that the droplets coalesce with the larger drops of first liquid, allowing the resulting "primary dispersion" to disengage under gravity, and recovering disengaged second liquid now depleted in "secondary dispersion"-sized droplets of the first liquid. Oil-in-water or water-in-oil dispersions are separated thus. In Fig. 1 the dispersion flows from the mixer to a separate coalescer-gravity separator unit, from which some first liquid is returned to the mixer. In Fig. 3 the heavy and light constituents separate by gravity alone into quiescent lower and upper zones of the mixer chamber, separated from the central mixing zone by baffles or coalescer pads.

Title: Apparatus for identifying Sheet-like Printed Matters
IPC: G07D7/00
Filed: 1979-11-08
Abstract: Apparatus for validating sheet-like objects comprises sensors 36, 40, 54, 56 for detecting a plurality of positions of moving sheet 12 (e.g. printed matter) to produce a plurality of position signals, a timing signal generator for producing signals on the basis of the position signals, light source 46 for irradiating an area on the sheet path to determine characteristics of the sheet. Photodetectors 48, 50, 52, 58, 60, 62 produce signals with amplitudes corresponding to the intensity of light transmitted through or reflected from the sheet and also signals with amplitudes corresponding to the intensity of light when the sheet is absent from the detection area. The photodetector outputs are integrated over the period when the sheet is in the detection area and over the period with the sheet absent. The ratio of the result of the two integrations is used to determine sheet validity. <IMAGE>

Title: Three-point ball bearing
IPC: F16C19/16
Filed: 1980-03-06
Abstract: The invention relates to a three- point ball bearing having a first bearing part (10, 12, 15) which forms a rolling surface (14) parallel to the axis and two essentially radial rolling surfaces (11, 13), and a second bearing part (17) which is rotationally mobile relative to the first bearing part and forms two rolling surfaces (18, 19) which are in each case located opposite the two abovementioned rolling surfaces and are inclined in opposite directions. According to the invention, the rolling surface (14) parallel to the axis is formed by a ring (15) which is elastically yielding in the radial direction. The result is that the bearing can work substantially without play at differing temperatures and can nevertheless absorb axial and tilting forces on the rigid rolling surfaces (11, 13), while remaining essentially rigid. <IMAGE>

Abstract: A launching and recovery apparatus for a lifeboat, rescue launch or like small boat fitted to a ship, floating or fixed marine platform or other vessel controlled by a single fall and comprises a launching and recovery cradle 7 from which a boat can hang freely on a releaseable support. During its travel between a fully hoisted and a partly lowered position the boat and cradle are supported on trackways 2a extending inwardly and upwardly from the deck of the vessel by roller assemblies 31, 32 at the base of the cradle which run on respective trackways. The cradle 7 has a symmetrical upwardly convergent frame whose apex is arranged for connection of the single fall wire 43 by which the cradle is held in a stable attitude during launching and recovery with the boat suspended freely from the cradle on a single releaseable support 38. A single sheave 15 located above the cradle symmetrically between the trackways 2a takes up or pays out the fall wire 43, to raise or lower the cradle 7. The boat is suspended from a position well above its centre of gravity which assists stability in roll and pitch. <IMAGE>

Abstract: A tyre pressure monitoring system includes a tuned circuit (10) comprising an inductor (11), with a pressure sensitive switch (13) which is closed when the tyre pressure is normal, connected across it, the tuned circuit and switch being mounted on a vehicle wheel. Mounted on a part of the vehicle is a detector circuit including an oscillator (14) which includes an inductor (15) which is at least intermittently magnetically coupled to the inductor (11) of the tuned circuit (10).

When switch (13) is open, however, the oscillator output is suppressed whenever the inductors (11, 15) are coupled together. The circuit can also be used in other applications where it is required to detect the condition of an isolated switch contact. <IMAGE>

Title: A method and apparatus for measuring tube wall thickness
IPC: G01B15/02
Filed: 1980-10-10
Abstract: Sources 1A, 1B, 1C direct at least three beams 3A, 3B, 3C of radiation of known intensity through the tube 20 so as to intersect at measuring points A, B, C within the tube wall. Detectors 4A, 4B, 4C receive the emergent beams and measure their intensities. The attenuation of the beams is used to determine the tube wall thickness x1, x2, x3 at the measuring points A, B, C. The determination may make use of the method of least squares and may be effected by means of a computer. Measuring points common to a beam path may be spaced axially of the tube. An additional measuring point may be on only one beam path which passes through another measuring point at which beam paths intersect. <IMAGE>
