Abstract: 441,410. Television. WILSON, J. C., 24, Whitworth Park Mansions, Moss Lane East, Manchester, and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. July 26, 1934, No. 21827. [Class 40 (iii)] Television scanning apparatus for producing traversal of the type in which successively scanned strips are arranged in regular lateral progression from one edge of the traversed field to an opposite edge comprises a frusto-conical drum 12 having mirrors 2 arranged on the peripheral surface thereof to form a plurality of convolutions of a continuous spiro-helical track. Light from the scanning aperture 7 is projected by a lens 8 on to a facet of a polyhedral reflector 13 by which it is continuously directed to impinge on the mirrors of each convolution in turn on the drum 12. The lens 8 may form an image of the element 7 at the surface of the polyhedron 13 provided an additional lens is inserted at some convenient place in the remaining optical path to the screen 9 in order to bring into focus, as at 10, 11, an image of the image cast by the lens 8. The mirrors may be plane or may have a cylindrical curvature and the polyhedron 13 may be replaced by a vibrating or reciprocating mirror. British Specifications 253,957, [Class 40 (iii)], and 381,898 and U.S.A. Specification 1,787,920 are referred to. The Provisional Specification describes a right-cylindrical drum carrying a plurality of reflectors arranged in a helical track of more than one convolution, a suitable shutter being interposed between the scanning aperture and the drum.

Abstract: 516,162. Stiffening textiles. ROTTA, W., [trading as CHEMISCHE FABRIK T. ROTTA], and QUEHL, K. July 26, 1938, No. 22198. Convention date, July 26, 1937. [Class 15 (ii)] Wash-resistant stiffening effects are obtained on textile material consisting of or comprising natural or artificial cellulose fibres by treating them with an aqueous solution of swelling agent, present in concentration insufficient alone to cause swelling, the solution containing an addition of calcium and or magnesium salts, other than thiocyanates, which by themselves cannot produce swelling. The salts used may be chlorides. The treatment is carried out so that no parchmeritizing is effected. The swelling agent may be formic acid, zinc chloride, or calcium thiocyanate. The solution may contain wetting or softening agents such as glycerine or dressing agents such as urea. In an example, regenerated cellulose fabric is treated at 50‹C. with a solution of calcium chloride and calcium thiocyanate. The fabric is centrifuged, rinsed, and dried. A cotton fabric is treated with a warm solution of calcium chloride, zinc chloride, and urea. The fabric is squeezed, rinsed, and dried. In another example, a cloth of cellulose artificial wool is treated with a solution of formic acid and calcium chloride.

Title: System for automatically obtaining an aircraft bearing and a fix
IPC: G01S5/00
Filed: 1974-05-20
Abstract: 1413457 Radio navigation ROHDE & SCHWARZ 20 May 1974 [24 May 1973] 22397/74 Heading H4D In a system for automatically obtaining the bearing of an aircraft 3, a message is sent on the radio set of said aircraft which is received at a direction-finding ground station where the bearing is measured and the message is at least partially stored in a recording set 7. A ground transmitter 9 controlled by the recording set automatically operates when the measurement has been made, and retransmits at least part of the received message and the bearing. The aircraft is thus able to verify, by reception of part of its own message, that the bearing relates to it. As described, the direction-finding station is provided with a Doppler aerial array 1 and an associated receiver 2 which automatically measures the aircraft bearing. The radio frequency used may be 122À5 MHz. The result appears in the output 5 of the receiver 2 as a analogue or coded signal. At the same time, the content of the pilot's message appears at another output 6. The two outputs are taken to a recording device which may, for example, have a magnetic disc, tape or cylinder. The recording set 7 contains a translator 8 for converting the output 5 into a corresponsing speech signal. This may comprise a multiple track record carrier on which adjacent tracks carry the numbers 0, 1, ... 9, and each of which is associated with a replay head. A digital signal from the output 5 of the receiver 2 activates the appropriate replay heads in sequence. If the output 5 is not in digital form a suitable converter must be incorporated. The same record carrier may contain additional tracks for other speech signals, e.g., the ground station identification code, &c. Output from the recording set 7 modulates the ground transmitter 10, which transmits in the same frequency band as the aircraft on an aerial 10. Should several direction-finding stations be within range of the aircraft it may be arranged that their replies are staggered in time, so that they may be distinguished from one another by the pilot. Thus, if re-transmission of a bearing takes 10 seconds, one station may reply after a delay of 3 seconds, a second after 13 seconds, a third after 23 seconds, &c. From the results of a plurality of such bearing measurements, the aircraft may obtain a position fix.
