Title: Improvements in and relating to discharge lamp circuits
IPC: H05B41/232
Filed: 1947-04-03
Abstract: 634,510. Supply systems for discharge lamps. SERNER, A., and CROMPTON PARKINSON, Ltd. April 3, 1947, No. 9155. [Class 38 (iv)] A transformer having two secondary windings S1, S2 for supplying heating current to the individual filamentary electrodes of a discharge lamp D has a primary winding PO connected in series with a condenser C in a non-resonant circuit across the current supply leads. The condenser voltage is effective for starting the lamp and is substantially independent of the voltage drop across the lamp or of the value of the stabilizing ballast LO which is connected in series with the lamp in a circuit in parallel relation with the condenser. When the lamp starts the wattless compound of the lamp current reduces the excitation of the transformer and the current in the electrodes, a second primary winding PX being provided in the arrangement according to Fig. 2 wherein a condenser CX makes the lamp current lead. When such condenser is not used the lamp current is taken through the primary winding PO by a direct connection from an electrode to a point between the condenser C and winding PO. Specification 634,509 is referred to.

Title: Quick-curing aminoplast resins and process for the manufacture thereof
IPC: C08G12/26
Filed: 1965-03-05
Abstract: An aminoplast resin is prepared by reacting in neutral or weakly alkaline solution at an elevated temperature, an aminotriazine with HCHO, in a molar ratio of between 1:4 and 1:9, together with 5-35%, related to the weight of the resin, of a polyhydroxy compound or sugar containing at least 5 C in a molecule, 0.2-1.5 mol of a salt of sulphamic acid per mol of aminotriazine, as well as, optionally, up to 50% of the weight of the resin, of urea, dicyandiamide, a guanamine or s-triazinone and condensing to give a product, a sample of which adjusted with water to a resin content of 50% by weight would change into a solid gel, in a period of between 8 minutes and 90 minutes if heated in a boiling water bath. In Example (1) aqueous HCHO, K2CO3, sucrose, an aqueous solution of the sodium salt of sulphamic acid, melamine and urea were mixed and reacted together at 85 DEG  C. until a sample, when diluted with 2.5 volumes of saturated aqueous NaCl solution became just turbid.  The curing time of the resin sample thus obtained before a solid gel is formed when heated on a boiling water bath was about 60 minutes.ALSO:In Example (1) a perlon-rayon lace fabric was impregnated with a solution containing amino ethylpropanol hydrochloride and an aminoplast resin solution prepared from aqueous HCHO, K2CO3, sucrose, urea, melamine and the sodium salt of sulphamic acid by heating to 85 DEG C. until a sample on dilution with 2.5 volumes of saturated aqueous NaCl just turned turbid.  The impregnated lace fabric was then heated for 2 mins at 160 DEG C. and produced a stiffened effect that was fast to washing. In Example (3) a 10% aqueous solution of an aminoplast resin prepared by reaction of aqueous HCHO, sorbitol, melamine, urea in the presence of K2CO3 and an aqueous solution of the sodium salt of sulphanic acid at 85 DEG C., was mixed with concentrated HCl.  This resin solution was then mixed with a paper pulp containing bleached sulphite cellulose, rosin size and Al2(SO4)3 and a paper sheet manufactured therefrom.

Title: Timing correction for a video signal processing system
Inventor: CHRISTOPHER TODD J
IPC: H04N5/45
Filed: 1996-10-10
Abstract: System performance of picture-in-picture video display systems is dependent on critical timing relationships between the incoming signals and the clock signals used to sample and display both the large picture and small picture signals. Video signals from various sources, e.g. VTR's, tend to have jittering time bases which may cause the small image to appear jagged or tilted. This distortion in the small image may be reduced by effecting adaptive signal delays in the small picture signal responsive to the relative phase of the system clock signal with respect to the horizontal synchronizing pulses of the large and/or small picture signal. One phase measure is used to control an interpolator which combines successive samples of the small picture signal in proportions to develop sample values corresponding to samples that would have occurred had the small picture signal been sampled by a clock properly aligned to the small picture horizontal synchronizing pulses. A second phase measure is used to delay the clock signal used to display the small picture so that the clock pulses that define the edges of the small picture occurs with the same timing relative to the large picture horizontal synchronizing pulses form line-to-line.

IPC: B01D53/04
Filed: 1983-01-06
Abstract: PURPOSE:To reduce the variation in the dew point of a drying gas at the begining of the changing-over of the dehumidifying tower of which the reproduction has been completed by lowering the temp. of a desiccant, by flowing a part of drying gas having a temp. lower than that of the desiccant into the other dehumidifying tower in the post- stage of the desiccant cooling process of a two-tower change-over type dehumidifying apparatus. CONSTITUTION:Valves 20, 16, 7, 13, 14 are opened and air from an air intake port 25 is heated by a heater 23 while heated air is passed through a dehumidifying tower 3 to evaporate the moisture of a desiccant and discharged from a discharge port 26. In the next step, valves 14, 16, 20, 21 are closed and valves 15, 18 are opened while cooled dehumidified air is flowed into the dehumidifying tower 3 to perform the primary cooling of the desiccant and the air issued from the dehumidifying tower 3 is returned to a cooler 24 through the valves 7, 15. After the interior of the dehumidifying tower 3 is purged with dry inert gas supplied from a dehumidifying tower 2 through a pipeline 27, the valves 7, 13 are closed and valves 9, 11 are opened while a part of inert gas being gas to be dried already cooled by a cooler is flowed into the dehumidifying tower 3 from a gas inlet 4 to perform the secondary cooling of the desiccant. The gas issued from the dehumidifying tower is combined with the dry gas issued from the dehumidifying tower 2.
