Title: Improved process for hardening casein fibres
Inventor: FARBENINDUSTRIE AKTIENGESELLSC
IPC: H04M3/523
Filed: 1938-03-10
Abstract: 512,640. Casein fibres. I.G. FARBENINDUSTRIE AKT.-GES. March 10, 1938. No. 7505. Convention date, April 27, 1937. [Class 2 (ii)] Casein fibres are hardened by the action of a solution containing an aldehyde such as formaldehyde and more than 15 per cent. of a water-soluble salt. Suitable water-soluble salts are chlorides of sodium, potassium, or magnesium, sulphates of sodium, ammonium magnesium, or aluminium, alums, citrates, tartrates, etc. When salts of ammonium are used, these react with formaldehyde to form salts of hexa-methylene tetramine. The fibres may be passed' continuously through the treatment bath or they may be treated on the spool or in hank form or as cut staple. They may be squeezed between rollers before treatment. The fibres may pass directly from the coagulation bath to the hardening step, or they may be washed with a salt solution after coagulation and before hardening. In examples, a solution of casein in caustic soda containing urea is spun into a bath containing sulphuric acid and sulphates and the coagulated fibres either in continuous length or in the form of staple, are hardened with a solution containing formaldehyde, sulphuric acid, and watersoluble salts. Specification 483,731 is referred to. The Specification as open to inspection under Sect. 91 refers to the treatment of casein fibres with aldehyde alone followed or preceded by treatment with a water-soluble salt, the coagulation of casein fibres in a bath containing a water-soluble salt followed by treatment of' the fibres with aldehyde while they still have coagulating bath liquid adhering to them and the coagulation with simultaneous hardening of casein fibres in a bath containing an aldehyde and a water-soluble salt. This subject-matter does not appear in the Specification as accepted.

Filed: 1925-03-20
Abstract: 244,034. Soc. Anon. des Automobiles Unic. Dec. 8, 1924, [Convention date]. Automatic speed control; pneumatic trans. mission.-The speed of engines, particularly for motor vehicles, is regulated by means of a throttling device controlling the supply of mixture to the engine and displaceable in a member on the mixture conduit with sufficient play to allow engine suction to act on both sides of the device, the suction on one side being modified by one or more speed regulators which admit air or gas to conduits leading to the device. One such regulator may be placed on the engine shaft and another on the propeller shaft beyond the changespeed gear. Fig. 3 shows a throttling device consisting of a plunger a, which is.formed at its lower end as a throttle e controlling the mixture conduit c and is acted on at its upper end by the engine suction and by air or gas admitted by connections g to the speed governors. When the higher speed gears are in use, the governor on the propeller shaft has a controlling action on the plunger, and for lower speed gears the governor on the engine shaft. Fig. 6 shows a form of centrifugal governor in which balls h sliding in slots i act on a conical sleeve D which, through a lever q, s opens a valve v to admit air to a pipe E leading to the plunger a, Fig. 3. The tension of the spring w acting on the valve v is adjusted by means of a screwed cap d<1>. The sleeve D, instead of being formed with conical surfaces engaging the balls, may have curved surfaces shaped to give the desired result. The plunger a may be replaced by a plate I, Fig. 5, pivoted at B' and subjected to the engine suction so as to actuate a throttle K<1>. Hand-controlled valves may be provided in the connections between the throttle device and the governors. The Specification as open to inspection under Sect. 91 of the Act states also that the throttling device may be a diaphragm. This subject-matter does not appear in the Specification as accepted.

Title: Apparatus for measuring moisture content of moving dielectric materials
IPC: G01N27/22
Filed: 1975-02-25
Abstract: 1485317 Measuring moisture content electrically GORKOV SPETSIAL UPRAV PO MONTAZH REMONT MODERN I NALADKE TEKHNOLOGICHE OBORUD 25 Feb 1975 [18 April 1974] 7893/75 Heading GIN The moisture content of a moving dielectric material e.g. paper is monitored by measuring the intensity of the electro-magnetic field originating from static electric discharges by means of an aerial and receiver circuit. Aerial 2 is positioned adjacent paper web 1 and is coupled via band pass filter 4, detector 5, and inverter 6 directly to, in the simplest arrangement Fig. 1 (not shown), a meter or recorder 10. Since the charge on the paper is the greater the drier is the paper and hence the intensity of the e.m. field caused by the discharges of the charge between the paper and roll 3 is greater, the signal produced at the output of the inverter is directly related to the moisture content of the web 1. The inverter 6 is in the form of an operational amplifier 7 to one input of which is applied a reference voltage U o  and which operates in the manner of a scaling amplifier. The output of the inverter may be fed to the meter 10 via a comparator circuit 11 including an operational amplifier threshold circuit 12 and transistor 13 in order to preclude occurrence of a false signal upon breakage of the moving material. When the detector 5 output is lower than the pre-selected reference voltage U 1  transistor 13 is turned on to supply the output of the inverter 6 to meter 10. If there is no signal picked up the aerial 2 transistor 13 is turned off and the meter 10 is disconnected. To provide a warning of overload conditions of the apparatus the inverter 6 output is fed to the input of the threshold circuit 16 of a comparator 15. When the voltage picked up at 2 is within the working range transistor 17 is off and lamp 18 does not glow. Should the signal exceed the range the inverter 6 changes its polarity so that transistor 17 is turned on and the lamp 18 glows. The signals produced by the inverter may be used to control the moisture content of the web.
