Abstract: 362,180. Air-break switches. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London.-(Assignees. of Koppitz, C. G. ; of Railway & Industrial Engineering Co., Greensburg, Pennsylvania, U.S.A.) Dec. 19, 1930, No. 38355. Convention date, Dec. 19, 1929. [Class 38 (v).] Contacts.-An insulator 3 is rotatable about its axis to bring a movable contact 21 on an arm 20 into engagement with a fixed contact 7, 8, of which the part 7 is of hard metal such as weather-proofed steel, and 8 is of copper. The part 7 is secured in a socket 9 by running in melted zinc. The contact 21 is arranged to enter the contact 7, 8 in the inclined position shown in Fig. 5 and, after abutting a stop 10, to be rotated with the arm 20 so that its major axis is transverse the U-contact, thereby cleaning the latter. For producing this movement, the arm 20 is rotatably mounted in a trunnion 19 that can rotate in, or with, a member 13 which is secured to the insulator 3 for rotation therewith. The arm 20 carries a bevel wheel 22 meshing with a rack 28 on the member 13, and a torsion spring 24 is anchored at one end 25 to the arm 20 and at the other end 26 to a member 27 secured to the trunnion 19. The spring 24 is sufficiently strong to cause the arm 20 to rotate with the insulator 3 about the axis of the latter, until the arm 20 engages the stop 10, whereupon the arm is rotated about its own axis by the bevel' gearing and the spring is stressed. In a modification, Fig. 3 (not shown), the spring may encircle the switch arm beyond the trunnion.

Abstract: 1,003,024. Heat-treating protein-containing foods. A. B. TETRA PAK. Oct. 1, 1963 [Oct. 8, 1962], No. 38613/63. Drawings to Specification. Heading A2D. In the heat treatment of a proteincontaining food product, e.g. milk and cream, the product is heated to a temperature substantially above the minimum temperature at which protein-decomposition occurs with resultant deterioration of taste, and during and/or after such treatment the food product is oxygenated. The minimum temperature referred to is in the neighbourhood of 80C., according to the invention heating may be carried out at such higher temperatures as between 110C. and 120C. The oxygenation may be effected by injecting steam mixed with oxygen or with oxygen-containing gas into the food product, by spraying the food product in atomized condition into a chamber containing an atmosphere rich in oxygen, by passing the food product through an oxygen-rich atmosphere as a continuous film, or by bubbling oxygen through the food product. Pressures greater or less than atmospheric pressure may be employed for the oxygenisation. Oxygen may also be dissolved in the food product before the heat treatment. Oxygenation after the heat-treatment may be effected in the storage receptacle, any residual oxygen after a period of storage being removed by application of a vacuum. The oxygen may be presennted as a donor containing oxygen, e.g. hydrogen peroxide.

Abstract: 1358931 Ultrasonic Doppler devices AEROSPACE RESEARCH Inc 24 Aug 1971 [3 Sept 1970] 39525/71 Heading H4D [Also in Division G4] An ultrasonic alarm system wherein a space to be supervised is illuminated by ultrasonic radiation which is reflected back, received and processed employs means for distinguishing a Doppler shift spectrum caused by background "interference", e.g. convection currents, traffic vibration, &c. from such a spectrum caused by the movement of an intruder within the space by detecting whether the spectrum is symmetrical or asymmetrical about the carrier frequency. It is stated that such a symmetrical spectrum, (13) Fig. 1B, (not shown), is produced only by interference and in a first embodiment, Fig. 2, the received signal at 24 is compared at 26 with a reference to produce signals at 28, 30 whenever the received signal lies in an upper sideband or lower sideband respectively. The outputs are full wave rectified at 34, 38, to yield respectively a positive and negative signal which are summed at 40 and integrated at 42 to activate an alarm 46 whenever a threshold 44 is exceeded. In the event only of a symmetrical Doppler spectrum, the signals in the summer and integrator will yield zero over any integrating period. The second embodiment, Fig. 6, the received signal is mixed with two quadrature reference signals, Fig. 4 (not shown), and the two resultant envelope signals are added and subtracted to form two signals proportional to Cos #t and sin #t where # is proportional to an instantaneous Doppler shift. If 0 is positive then the one wave will lead the other and vice versa if # is negative. The two signals are filtered at 86, 88 and compared with ground potential at 90, 92 to produce positive or negative outputs which are taken as inputs to a flip-flop 94, one acting as a clocking input to display at the output Q the polarity applied at D at the clocking instant. If the signal at D is leading that at clock, then the Q output will always be positive and vice-versa when D is lagging. The output Q causes corresponding one of two positive or negative full wave rectified detector outputs indicative of the instant Doppler level 102, 104 to be passed to the integrator 98 and thence via threshold 100 to an alarm. If the spectrum is asymmetrical, on more occasions will one signal lead or lag the other than vice-versa and an output alarm is produced.
