Title: Method of preparing closed cell phenol-aldehyde foam and the closed cell foam thus prepared
IPC: C08J9/12
Filed: 1977-06-06
Abstract: Closed cell phenol-aldehyde foam is prepared by a method which includes a novel frothing and curing technique. An admixture containing a liquid phenolaldehyde resole resin, a volatile blowing agent, and a surfactant is frothed to produce a stable froth containing closed cells. The cell walls are formed of the liquid resole resin and the closed cells are expanded by the blowing agent in gaseous phase. The froth is formed into an uncured shape and the liquid resole resin is cured to the solid state in the presence of an acid catalyst to produce cured closed cell foam. The internal temperature throughout the shape during curing is above the boiling point of the blowing agent but less than 212 DEG F., and is sufficiently low to prevent further expansion of the shape in an amount to rupture the closed cell walls and thereby form an open cell structure. The liquid resole resin has a sufficiently low exothermic heat of reaction and the acid catalyst is present in an amount whereby the internal temperature of the shape during curing is less than 212 DEG F. and within the aforesaid limits. The improved closed cell foam thus prepared is also provided.

Title: Gas-venting arrangement incorporated with a mold
IPC: B29C33/10
Filed: 1980-09-26
Abstract: An arrangement incorporated with a mold for use in a die casting machine or an injection mold machine comprising: a gas vent passage formed in the mold communicating with a cavity of the mold two symmetrical by-pass passages branched from the gas vent passage a gas discharge passage communicating with the outside of the mold and valve means including a valve chamber formed in the mold having a valve located therein and communicating with the above-mentioned passages. The valve in a first position cooperates with the valve chamber to prevent the gas vent passage from communicating with the gas discharge passage, but prevents both the gas vent passage and the by-pass passages from communicating with the gas discharge passage when in a second position. A portion of the melt forced to flow from the cavity through the gas vent passage upon impingement of that portion of the melt against the valve drives the valve from the first position to the second position before any of the melt forced to flow through the by-pass passages reaches the valve chamber.

Title: Device for the removal of warts using liquid nitrogen.
IPC: A61B17/00
Filed: 1981-11-05
Abstract: In a device for removing warts using liquid nitrogen, a metallic cooling rod (12) is provided, in whose inside a temperature sensor (4) is arranged. The temperature sensor is connected to an electrical temperature measurement device by way of a cable connection. For removing the warts, the cable connection is detached and an insulating tube is pushed over the cooling rod, with which tube the cooling rod is gripped and treatment is carried out. A temperature check during treatment is not possible. The treating physician therefore requires a great deal of experience in order to meter the cold supply to the optimum effect. In order to simplify treatment, the cooling rod is held in a pistol-like grip (1) in which the temperature measuring device (5) is arranged and on which the temperature display (8, 9) is situated. The temperature can be indicated visually or by sound. The device is optimised by means of a time-measuring facility (10) arranged on the grip.

Title: Process for recovering uranium.
IPC: C22B60/02
Filed: 1982-02-26
Abstract: A process is described for the recovery or uranium from wet-process phosphoric acid utilizing an alkyl pyrophosphoric extractant. The extractant also contains a modifier for retaining the alkyl pyrophosphoric acid ester in solution in an essentially water-immiscible organic diluent during stripping. After extracting the uranium from wet-process acid, the APPA extractant is treated with an oxidizing agent such as hydrogen peroxide and the uranium stripped into an alkaline stripping solution. The alkaline stripping solution is an aqueous solution of an alkali metal or ammonium carbonate unsaturated in uranium. The barren extractant is recycled for contacting with fresh wet-process acid. Any ferric iron present is precipitated in the stripping solution and then separated from the solution. The uranium is precipitated, separated, dried and calcined to a U3O8 product.

Abstract: PCT No. PCT/SE82/00363 Sec. 371 Date Jun. 16, 1983 Sec. 102(e) Date Jun. 16, 1983 PCT Filed Nov. 2, 1982 PCT Pub. No. WO83/01716 PCT Pub. Date May 11, 1983.A method and an apparatus, in a telecommunication system for transmission of digital information in duplex over a signal conductor pair for automatically adjusting a balance filter included in a hybrid coupler circuit with the aid of adaptive echo cancellation so that the local data transmitter does not disturb the local data reception, without utilizing any particular testing procedure in initiating the adaptive echo cancellation. A control signal ( epsilon k) is formed, with the help of which the correction unit (KB) is caused to generate signals for rapid updating of the balance filter (B) parameters, in spite of that knowledge is lacking in the initiation instant concerning the value of the signal transmitted from the remote end to the apparatus, and that no counteraction between level correction and filter adaption is obtained. The apparatus includes a quantizer (Q) in which a sampled, received signal (rk) is quantized, an estimated signal (âk) of data sent from the remote end being obtained. Said estimated signal is multiplied by a reference signal from a reference unit (V), the result being subtracted from the received signal (rk) so that an error signal (e k) is formed. The sign of the error signal is correlated with the estimated signal (âk) in a correction unit (KV), which calculates a correction ( DELTA V) which is added to the reference signal in order to correct it. The sign of the error signal (ek) is also added to the estimated signal (âk) thereby forming said control signal ( epsilon k) which is correlated with the data vector (bk) in the correction unit (KB) which calculates a correction value ( DELTA c) which is supplied to the input of the balance filter for correction of the filter parameters.

Patent ES-8404061-A1 (ES)
Title: Crossed beam high frequency anti-theft system.
IPC: G08B13/24
Filed: 1983-04-06
Abstract: An article surveillance system employs a label or tag containing a non-linear impedance element, such as a semi-conductor diode, connected to a metal antenna loop configured to pick up two distinct radio frequency transmissions displaced on either side of a selected center frequency. The non-linear impedance element connects opposing sides of a closed loop section at one end of the antenna to form a tuned tank circuit having a resonant frequency twice that of the selected center frequency. A first transmitter generates a tone modulated radio frequency displaced on one side of the center frequency, and a second transmitter generates a continuous wave radio frequency displaced from the center frequency on the other side. Both transmitter signals are fed separately to respective radiating antennae located adjacent to a surveillance area. The antennae are chosen to produce circularly polarized transmission of both frequencies within the surveillance area. The two different frequencies picked up by the transponder antenna are mixed by the non-linear impedance causing the tank circuit to resonate at a single higher frequency equal to their sum, which is double the center frequency that resonant frequency is reradiated to be picked up by a receiver antenna or antennae suitably placed with respect to the surveillance zone to be detected by a very narrow band receiver responsive to the sum frequency. The modulating tone signal is derived from the received signal to produce a gradually increasing charge that is compared against a preselected threshold level to trigger an alarm for a fixed interval only when the detected signal is of a sufficient strength and duration.
