Abstract: 170,381. Drõger, A. B. July 17, 1920. Respirators.-Means for automatically controlling, in respiratory apparatus, the supply of oxygen, comprises a collapsable chamber, separate from the main breathing bag. adapted to operate a valve and situated in the supply pipe between the breathing bag and the oxygen cylinder. In the form shown in Figs. 1 and 2, the collapsable chamber i is placed between the parts h, h' of the pipe leading from the pressure reducing valve g of the oxygen cylinder f to the connection d connecting the pipe with the breathing bag s. In the interior of the bag i are situated two plates r, l pivoted to a valve seating o and normally forced apart by a spring u. Pivoted to the seating is a bent lever y the short arm of which is in contact with the spindle n of a valve X, the spring of which forces the longer arm of the lever y against the plate l. The supplementary bag i is wired on the pipe h and the valve seating o. In operation, decrease of pressure in the breathing bag s causes the bag i to collapse and open the valve o to admit a further supply of oxygen. In a modification the collapsable bag is replaced by a rigid cup-shaped receptacle, the open end being closed by a flexible diaphragm the movement of which under atmospheric pressure serves to operate the valve controlling the oxygen supply, the reducing valve being dispensed with in this form. Two embodiments of this modification are described, and in the form shown in Fig. 5 a rubber valve 6 closing the entrance pipe q from the oxygen cylinder is carried by a spring-controlled, centrally-pivoted lever 4, movement of which in opposition to the spring f<1> is effected on the movement of the diaphragm m' through levers 12, 9, the second being rectangular in form and constructed of strip metal.

Abstract: 468,106. Felted fibrous cellulosic sheets. BURGESS, A. F. (Paper Patents Co.) Aug. 7, 1936, No. 21786. Drawings to Specification. [Class 96] A felted fibrous cellulosic product in the form of a crÛped sheet of gossamer thinness is made from a furnish in which there has been mixed 10-50 per cent of asphalt which is relatively brittle at room temperature and has a melting point between 140‹ F. and 200‹ F. A number of such sheets may be combined to form a multiply bat or pad for use as a heat or sound insulating material. Preferably the crÛped sheets have a basis weight of 4À9 lbs. for 480 sheets (24" x 36"). The sheets are made upon machines as ordinarily employed for making thin sheets for packing wadding, and are dried upon a Yankee drier from which they are removed by a crÛping doctor. The sheets are water repellent and may readily be fireproofed e.g. by spraying suitable solutions on to the drying web. Alkaline adhesive solutions such as sodium silicate may also be applied to the asphalt containing products without adversely affecting their water repellent characteristics. In an example, two parts of commercial asphalt having the desired properties are mixed with one part of ground wood and one part of unbleached sulphite fibre, and the furnish supplied to the machine contains 400 lbs. of this mixture together with 300 lbs. of unbleached sulphite pulp and 300 lbs. of ground wood. The sheets contain 20 per cent asphalt by weight. Sheets with 10 per cent asphalt are made from a furnish containing 200 lbs. of the mixture and 80 lbs. of unbleached sulphite pulp. In either case sufficient water is mixed with the furnish in the beaters to produce pulp suspension of about 3 per cent which is pumped to the paper making machine when it may be thinned with additional circulating water.

Abstract: 1331147 Electromagnetic switches, thermal switches MITSUBISHI DENKI KK 19 April 1971 [3 Feb 1970 (2)] 22129/71 Heading H1N A frequency responsive switch operative at either of two different superimposed frequencies can be used to operate a snap-action thermal switch controlling the energization of a load but is inoperative if both frequencies are applied. The coil 33 of the frequency relay has a tuning capacitor 19 in series and is connected to a main supply source (Fig. 1, not shown) which is arranged for control signals to be superimposed thereon. When a superimposed signal corresponding to the tuned frequency of a reed 35 is received the reed 35 vibrates so that a contact 49 on a weighted movable contact arm 23 is held in contact with a fixed contact 55 until the signal ceases. When a signal of the frequency of the reed 36 is superimposed on the main frefrequency the contacts 50, 56 are held closed. When contacts 49, 55 are closed a heater 27 of the thermal switch is energized so that after some delay a bi-metal 57 bends to snap-over a contact 77 into engagement with a fixed contact 80. When the heater 27 is switched off the contacts 77, 80 remain closed due to the snapaction mechanism formed by a compression spring 72 and the contact arm 68 to which one end of the two bimetal elements 57, 58 is attached. The contacts 77, 80 are opened when the snap-action mechanism is operated on heating of the bimetal element 58 by heater 26 which is in series with contacts 50, 50 of the frequency responsive switch. No switching occurs when both bimetals are heated.
