Title: Process for protecting wool, fur and the like, from attack by moth and other textile pests
Filed: 1929-05-15
Abstract: 333,583. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 15, 1929. Proofing against vermin ; proofing processes and compositions. - Wool, fur, and other materials are protected from attack by moth and other pests by treatment with an organic fluorine compound containing at least one fluorine atom attached to a carbon atom. Examples of suitable compounds are fluorine substituted aliphatic hydrocarbons, carboxylic acids, sulphonic acids and derivatives thereof, and fluorine substituted benzene compounds and homologues and derivatives thereof. The compounds may be dissolved in organic solvents or in water, and the materials sprayed or impregnated, or in some cases the compounds may be used in powdered form. In one example, wool is steeped in a 1 per cent aqueous solution of the sodium salt of 3-nitro-4- fluoro-1-benzoic acid. In a second example, 100 kilograms of wool are treated with a solution of 2 kilograms of monofluoroacetic acid in 1000 litres of water. An inorganic substance such as sodium sulphate and a wetting agent may be added. A 0.4 per cent aqueous solution of 1- fluoro-naphthalene-5-sulphonic acid may be used. In a further example, 2 parts by weight of 4 : 4<1>-difluoro-diphenyl are dissolved in 100 parts of an organic solvent such as alcohol, and 100 parts by weight of wool are soaked for about half an hour in the solution at room temperature. Fur &c. is kept in the presence of fluoro-pseudocumene in a closed vessel; the vapour effects the proofing. Similarly, furniture &c. is protected by treatment for 24 hours in closed apparatus with fluroform.

Bales of fibres are carried beneath a series of stations where the uppermost layers are disintegrated and the fibres conveyed pneumatically to a collecting point at which fibres from several stations are mixed. Wrappings from the upper part of each bale are released as the bale is carried by a conveyer 12 and wrappings from the lower part may be removed as the bale passes over the gap between conveyers 11, 12. By arranging conveyer 11 to have a slightly higher speed than conveyer 10 succeeding bales are brought into abutting relationship, in which condition they pass under the beaters 28 of fibre removal stations 271, 272 &c. of which there are fourteen in the described embodiment. Preferably two fibre removal stations operate upon one bale simultaneously. Each station includes a beater 28 and a spiked roller 34 that is driven at a speed correlated to that of the conveyer 10 to ensure an even advance of the layer of fibres being acted upon by the beater 28. Separated fibres are carried by the air-stream in the hood 47 through trunking to the common collecting station. The height of each beater 28 is adjustable and successive beaters may be arranged to remove layers of equal thickness dependent on the number of fibre removal stations. The conveyers 10,11,12 are preferably self-cleaning with conveying surfaces constituted by pivoted slats 60. The fibre collecting station may be a chamber spanned by an inclined stationary screen beneath which two parallel rollers rotate in opposite directions or may consist of a cage condenser. The trunks through which fibres are carried to the collecting station may incorporate cleaning grids.

Patent GB-1550088-A (GB)
Title: Doppler transmitting and receiving circuitry
IPC: A61B8/02
Filed: 1977-04-14
Abstract: The object of the heart rate meter is always to extract automatically from Doppler signals of the two pulsation directions of the heart, in particular of the foetus heart, those signals which are of optimum quality for determining the heart rate. This is achieved by means of two mixing stages (11, 12) for detecting Doppler signal components from the incoming movement separated in terms of both pulsation directions. Said components are fed through the ultrasonic receive signal (U6) and by in each case one of two signals of the transmission carrier frequency (U5) which are phase-shifted with respect to one another by the angle of 90 DEG . Each Doppler signal component (U7, U7') detected separately in accordance with the heart pulsation direction is fed respectively to an integrator (15, 16) for integration during a prescribable time interval, and the respective integration end value is stored by means of a memory element (17, 18) until the arrival of the next end value in each case. Via a respective frequency filter (20, 21) for the signal components (U10,U11) originating only from the movements of the heart wall, the memory signals (U9, U9') are fed to a phase comparator (22) which generates in time with periodic zero crossings of one signal component (U10) output pulses (U12) with the amplitude and plurality of the other signal component (U11). These output pulses are fed, on the one hand, via rectifiers (23, 24) and filters (26) as well as a frequency-doubling circuit (27) for frequency-wise distinction of one of the Doppler signal components from the other to a loudspeaker (29) for acoustic reproduction of the Doppler signals and, on the other hand, via an integrator (30), a threshold circuit (31) and a D/A convertor (32) to a display device (33) for displaying the heart frequency originating from the Doppler signal of larger amplitude. <IMAGE>

Title: Improvements in or relating to roller bearings
IPC: F16C23/08
Filed: 1933-06-02
Abstract: 404,866. Roller bearings. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN, 17, Artillerigatan, Gothenburg, Sweden. June 2, 1933, No. 16065. Convention date, Nov. 4, 1932. [Class 12 (i).] In a roller bearing having rollers 5 with symmetrical barrelshaped rolling surfaces disposed between a spherical race 2 and a non-spherical race 4, the races are so formed and disposed relative to each other that the resultant of the forces acting at the contact between a roller and one at least of the races is applied to the roller at one side of its greatest diameter d so as to press the roller end surface 8 against a pressure or guide flange 6 on one of the race rings. In Fig. 3 which shows the application of the invention to a double row bearing, the resultant reactions A, B of both races comply with this condition and produce a pressure equal to the reaction C on the guide flange 6. The rollers have line contact with the spherical race 2 of the outer bearing member and point contact at a point 16 with the non-spherical inner race. Preferably the end faces of the rollers are plane and the guide flange 6 has spherical side faces 9 so that the rollers make contact with the flange 6 along an arc of a circle. If the centres of these spherical side faces are at the points of intersection of the roller and bearing axes, the rollers contact with the flange 6 along their edges. If the centres of the faces 9 are located inwardly of these points of intersection, the rollers make contact with the flange 6 at two spaced points. A method of arriving at the profile of the inner race for a chosen point of application 16 of the reaction of the inner race is described in the Specification. End flanges 7 are provided to prevent the rollers falling out when not under load. The roller ends may be of spherical or other form and the side faces of the flange 6 may be conical. The profiles of the rollers and the non-spherical race may be of elliptical form. Both races may be arranged to make point contact or line contact with the rollers or the outer race may make point contact and the inner race line contact. The invention is applicable to bearings having one or more than two rows of rollers.
