Filed: 1932-08-12
Abstract: 405,694. Air-current indicator for determining scent conditions. BUDGETT, H. M., Kirtlington Park, Oxford. Aug. 12, 1932, Nos. 22611/32, 22612/32, and 21395/33. [Class 97 (iii).] Apparatus for indicating whether or not conditions are suitable for easily detecting the scent trail of animals is provided with means for ascertaining the presence of an air current rising from or flowing towards the surface of the earth. In one form, Fig. 7, an inverted funnel 51, adapted to rest on the ground, leads to a pipe 52, having a transparent portion 54 and a cowl 53 protecting its open end. A reticulated diaphragm 55, e.g. a spider's web, in the portion 54 indicates the direction of the air current by the direction in which it bulges. Alternatively the direction of the air current may be deduced from a comparison of the temperatures above and below the surface of the earth. A metal tube, which may have a crook handle, is provided at the bottom with a hollow spike in which the bulb of a thermometer is mounted and embedded in wax. A second thermometer is mounted in the tube so that its bulb lies above the surface of the ground when the spike is stuck into the ground. The thermometers are viewed through slots in the tube, which may be closed by a cylindrical shield when not is use. Alternatively the two thermometers may be replaced by a differential air thermometer. In a further modification, Fig. 5, a tube 1 carries at its top a casing 26, containing a battery 34, galvanometer 32 and standard resistances 31 forming two arms of a Wheatstone bridge the remaining two arms including respectively a resistance thermometer arranged in a hollow spike at the bottom of the tube 1 and a resistance thermometer 23 arranged in a tube 25 upstanding from the casing 26 and sheltered by a series of cowls 28.

Abstract: 833,177. Counting-apparatus. VEEDERROOT Inc..July 15, 1958 [July 25, 1957], No. 22643/58. Class 106 (1). ). In a counter in which the number wheels and/or transfer pinions are fabricated of a non- metallic material having a relatively high coefficient of thermal expansion and a relatively high hydroscopic coefficient, means are provided to compensate for variations in size of the expansible parts. As described, a counter has number wheels 20 of a non-metallic material referred to as nylon and associated mutilated tooth transfer pinions 30, and a driving pinion 34 also of nylon, the transfer pinions cooperating with a gear on the higher order number wheel and a transfer tooth and locking ring on the lower order number wheel in the conventional manner. The pinions 30, 34 are mounted on a shaft 31 supported in a yoke 36 whose end pieces 37 are pivotally mounted on a shaft 42 supported in the counter housing. A resetting lever 46 comprising arms 48 cooperating with heart cams 29 on the numeral wheels is pinned to the shaft 42, a torsion spring 52 mounted on the shaft 42 being adapted to urge the yoke 36 and resetting lever 46 towards each other. movement being limited by engagement of one of the arms 48 with an ear 40 on the yoke. Resetting is effected by depressing a plunger 64 arranged by a mechanical linkage to pivot the shaft 42 in a counterclockwise direction against the action of a spring 60, thereby pivoting the reset lever and arms correspondingly to return the number wheels to zero and, through the spring 52 causing counterclockwise pivoting of the yoke 36 to disengage the transfer pinions. The transfer pinions when disengaged are maintained in correct alignment relative to the number wheels by entering notches 68 in a fixed transfer pinion spacer plate 66. A stop member 70 engageable with the ear 40 limits clockwise rotation of the yoke. 36 and is also formed of nylon so that when expansion occurs the transfer pinions are moved radially outward thereby preventing binding of the number wheels and transfer pinions due to temperature and humidity changes. The stop member 70 is substantially semi-circular, having a diameter approximately equal to that of the number wheels, and is mounted eccentrically on the counter frame by a screw 72. In an alternative arrangement, Fig. 6, the transfer pinions are rotatably mounted on a shaft which is supported at either end by nylon brackets 84 loosely supported on the number wheel shaft 77.

Abstract: 663,637. Coffee. SOC. IMMOBILIERE & FINANCIERE DU PARC. Sept. 2, 1948 [Sept. 25, 1947], No. 23146/48. Class129 Coffee extract is prepared by distilling an aqueous slurry or suspension of roasted and ground coffee beans under a reduced pressure and at a low temperature, condensing the vapours until a distillate substantially equal to half the weight of the coffee beans used has been collected, then extracting the remainder of the slurry or suspension at a temperature of 90-95‹C. with an amount of water substantially equal to the initial weight of the' coffee. The slurry, which comprises 3 parts by weight of water to one part of coffee, is formed by kneading forabout an hour at a temperature of 40-50‹C. The distillation is effected at a temperature of preferably not more than 42‹C. at an absolute pressure of 70 cm. of mercury. For the extraction, a battery of extractors are used in a counter-current process. The extracting water passes upwardly through the last extractor and downwardly through the preceding ones. The extract may be concentrated to a syrup containing 45 per cent. of dry materials, drying being completed in the absence of air, e.g. in an atmosphere of nitrogen under reduced pressure. The dry product is added to the distillate, and the mixture is dried in the absence of oxygen at a low temperature. Sugar or a hydrolytic derivative thereof, such as glucose, dextrose or maltose is preferably added before the final drying. Alternatively, carbohydrates, such as fecula or starch are converted by hydrolysis to glucose, dextrose and maltose, which is concentrated to a syrup containing 45 per cent. of dry materials and added to the extract syrup. A beverage containing coffee and milk may be prepared as follows: 100 parts by weight of milk powder (which may be prepared in a manner described in detail in the Specification) are kneaded with 60 parts of sugar and 12 parts of coffee extract at a temperature of about 65‹C. and reduced pressure for an hour. The mixture is then cooled to 10‹C., a nitrogen draught being passed over the liquid surface to avoid oxidation. - Distillate is then added in the proportion of 2 gram to 100 gram, and the mixture is ground for 30 minutes in an inert atmosphere in the manner previously described.
