Title: Improved articles prepared wholly or in part from polythene compositions
IPC: C08J7/044
Filed: 1946-07-16
Abstract: Articles or coatings from polythene compositions, having anti-static properties, are made by a process which does not include the production or use of a dispersion of said composition, such that during, before or after said process the polythene composition, article or coating is treated with either a condensation product of ethylene oxide with either a water insoluble fatty alcohol or a water insoluble fatty acid; or with a saturated aliphatic alcohol containing more than 12, but not more than 32 carbon atoms. Saturated aliphatic alcohols specified are myristic, cetyl or stearyl alcohols to which higher unsaturated alcohols such as oleyl alcohol may be added.  The condensation products may be prepared according to Specification 380,431, and include products of ethylene oxide with capric, lauric, myristic, palmitic, stearic, montanic and naphthenic acids or with hexyl, decyl, lauryl, myristic, cetyl, stearyl and eicosyl alcohols. Acids from coconut oil or alcohols from sperm oil may also be used.  The anti-static agent may be ground with the polythene composition or dissolved or dispersed in a liquid and coated onto the polythene article such as a film, or coating.  Dyes such as "Monastral" (R.T.M.) Fast Green G.S., Blue Lake 24480, Cadmium Scarlet 1000, or Cadmium Tangerine 10105, and zinc oxide, and di-o-cresylol propane may be incorporated in the polythene compositions.

Title: Selective call devices for radio receiver
IPC: H04W88/02
Filed: 1970-05-04
Abstract: 1310742 Radio signalling ROBERT BOSCH ELEKTRONIK GmbH 4 May 1970 [2 May 1969] 21308/70 Heading H4L n a radio receiver which is responsive to at least two different calling signals, each consisting of a sequence of audio-frequency pulses and differing only in the last audio-frequency pulse of the sequence, an electronic counter in its zero position connects in a circuit tuned to the first frequency of the sequence and after each pulse has been received and identified as correct, connects in the circuit tuned to the next audio-frequency pulse of the sequence, the reception and identification of the penultimate pulse of the sequence connecting in a selective circuit provided with tuned circuits responsive to the audio-frequencies available for the last pulse of a calling sequence associated with the receiver. As shown in Fig. 1, incoming signals are demodulated at 2, limited at 3 and supplied to a transformer 7 having a tapped secondary winding tuned by a capacitor 13. Initially a counter 19 is in the zero position and supplies a potential to close transistor switch 14 so that the transformer is tuned to the first pulse of the calling sequence and this signal is rectified at 17, delayed at 18 and steps the counter to state 1. The ouput of the delay 18 also sets a monostable 24 which with normal operation remains set for the duration of the calling signal. The output of counter state 1 closes transistor switch 15, tuning the transformer to the second pulse of the sequence and after delay 18 the switch 16 is closed similarly by the counter at state 2. On reception of the third pulse, and after delay 18, the counter is stepped to state 3 to close transistor switch 26. This connects in three tuned circuits 27, 28, 29 responsive to the frequencies available for the last pulse of the calling signals appropriate to this receiver. Assuming that circuit 27 is tuned to the frequency of the fourth pulse, the voltage appearing across this circuit is rectified at 30, delayed at 31 and sets a bi-stable 33 to light a warning lamp 34. Energization of circuits 28, 29 operates lamps 41, 42 similarly and the calls are cancelled by operation of switch 43 resetting the bi-stable 33. On the termination of the calling signal, the monostable 24 is reset to return the counter to its zero state. In a modification, Fig. 2 (not shown), the tuned circuits relating to the last pulse of the calling signal are connected into circuit in sequence by a further counter instead of being connected in parallel.

Title: Method and Apparatus for Measuring the Flow Rate of a Fluid
IPC: G01F1/704
Filed: 1967-05-10
Abstract: 1,186,921. Radioisotopes. GAZ DE FRANCE. 10 May, 1967 [10 May, 1966], No. 21628/67. Heading G6R. [Also in Division G1] In the measurement of fluid flow rate using the dilution method involving injection of a radio-active isotope into the stream at one point and measurement of the radio-activity and mass of a sample collected at a point downstream of the injection point (see Division G1), the isotope is injected as it is produced by radio-active decay of its parent nuclide. One embodiment of the invention is described with reference to the determination of the rate of flow of methane in conduit 1. The isotope is injected into the gas stream in vapour form through nozzle 16 as it is produced from its parent material housed in a lead sheathed vessel 7. The isotope used is, for example, iodine 132 obtained from tellurium 132, which may be in the form of silver tellurite carried on a porous support in tube 7. In order to transport the daughter material from vessel 7, gas under pressure from chamber 23 forces an eluent (methyl alcohol) contained in tank 14 through chamber 7 to wash through the tellurite. Only the iodine is dissolved, and is carried into the conduit 1, where both the iodine and methyl alcohol are volatilized. Examples of other radio-active isotopes and their parent nuclides from which they are formed are given e.g. Radon 222, obtained from Radium 226, and used in measurement of air flow; Krypton 83, from Rubidium 83; Lead 212 and 211, from Thorium 228 and Actinium 227, respectively. In each case the parent has a much longer half-life than the daughter.

Class 82(ii) An upward current classifier, Fig. 1, comprises a liquid-containing riser 1 which is inclined to the vertical and in which an upward current is created, e.g. by compressed air from a pipe 2, and a widened upper portion 3, the wall of which is so shaped and inclined that, when the material to be classified is fed into the widened portion out of the path of the upward current, it slides down the wall and is directed across the liquid so that the light and/or small particles float and pass over the overflow 4 and the heavy and/or large particles sink to a receiver 6. The riser 1 is preferably at an angle of 10-30 degrees to the vertical and the wall of the upper widened portion 3 is preferably at an angle of 40-75 degrees to the riser at the point of infeed of the material to the upward current. In a further form shown, Fig. 2, the sinking particles from the riser 1 pass into a riser 9 in which the upward current is greater than that in the riser 1. The heaviest and/or largest particles therefore pass to the receiver 6 and an intermediate fraction is overflowed at 11. Several risers 9 may be used and the mixture separated into more than three fractions. In both forms shown the liquid drained from the overflow fraction is returned to the riser via the pipe 8 and the sink fraction is removed by the bucket conveyer 7.
