Filed: 1975-04-01
Abstract: 1502295 Control of broadcast receivers ITT INDUSTRIES Inc 1 April 1975 [2 April 1974] 13204/75 Heading H4L In a broadcast system in which special messages are broadcast from time to time, instead of the normal programme, each special message is preceded by an initial control signal having a frequency F, in the range 100-5000 Hz, amplitude modulated by frequency f and periodically modulated by frequency shifts alternately + #Fand -#F. The message is succeeded by a final signal of similar form but having frequency shift modulations of different magnitude #F<SP>1</SP> and - #F<SP>1</SP>. These initial and final signals control the broadcast receivers in the system, and these each include an identifying circuit such that in response to the initial control signals the receiver sound is increased, so that the message can be heard, and in response to the final signal the sound volume is turned down. The identification arrangement in the receiver incorporates a limiter-amplifier LA and a synchronous demodulator SD tuned to frequency F, whereby the control signals are amplitude modulated at the frequency f, the amplitude modulation depth being proportional to the frequency shift #F. The arrangement further includes a band pass filter BPF, a conventional detector D delivering a single polarity signal of amplitude proportional to #F, a trigger circuit T supplied with this signal and having two thresholds for detecting the initial and final signals respectively and a flip-flop FF supplied from the trigger circuit. This flip-flop both controls the receiver volume control and selects one of the two possible values for the trigger threshold, depending on its present condition.

Title: Improvements in or relating to stereoscopic optical systems
IPC: G02B27/22
Filed: 1941-10-16
Abstract: 548,158. Stereoscopic systems. MAINARDI, P., and MAINARDI, M. N. Oct. 16, 1941, No. 13348. Convention date, May 22. [Classes 97 (i)] and 98 (ii)] A stereoscopic optical system comprises a single lens in front of two images, an inner pair of reflectors in front of the lens, and an outer pair of reflectors, the reflectors being arranged so that rays between the inner and outer ones cross the optical axis of the lens; the reflectors may be embodied in a camera or projector, or in an attachment therefor, and may be arranged to turn the images through right angles in opposite directions about the axes of the beams. As shown in Fig. 4, outer reflectors 45 reflect rays from a scene through the nearer faces of a triangular prism 20 to be internally reflected by the opposite faces so as to pass through a lens 15 on to the image plane 17. The whole lens receives rays from each reflecting face of the prism, and the images 43 become oriented so as to be head to head. The image fields should be restricted by a mask 50 so that the upper rays 48 are horizontal, overlap of the film images and keystone distortion being thus avoided ; the axis 41 of the view finder system 39, 40 should be parallel to the central rays 32 of the image beams. Additional reflectors may be embodied in the system to produce a vertical film plane, and three arrangements of such reflectors are described. Fig. 11 shows an attachment for a projector 78 wherein the additional reflector 72 is, optically, between the reflectors 45 and colour filters 81 at the front window of the casing of the attachment, the filters enabling the projected images to be selectively perceived by the eyes of the spectators in known manner; the mask 76 is hingedly carried above the window. Fig. 6 shows a modification in which the prism 20 is replaced by mirrors 52, 53 having upper edges intersected by the lens axis. The prism 20, Fig. 7, may be arranged to reflect rays from both film images 59 vertically, the reflected rays being received by mirrors 61, 62 and directed to the screen 63. The images visible on the screen may be restricted to one pair by limiting the reflecting area of the screen by a mask &c., and complementary colour or polarizing filters 67, 68 may be provided in the image beams. The prism 20 has, preferably, an equilateral triangular section so that colour fringing of the beams may be a minimum ; if the section is not equilateral, it may be isosceles with a larger or smaller vertical angle, and glass wedges 84, Fig. 12, may be provided on the reflecting surfaces to reduce colour fringing, the apices of the prisms 84 being towards or away from the apex of the prism 20.

Patent GB-615564-A (GB)
Title: An improved manufacture of lubricating greases
Filed: 1946-05-02
Abstract: Anhydrous lubricating greases are prepared by a continuous process in which a hydrated hydroxide of lithium, barium or strontium is suspended in mineral lubricating oil, the hydroxide is dehydrated by heating the suspension, the slurry of anhydrous hydroxide thus formed is reacted with hot high molecular weight fatty acid at a temperature at which the soap formed by the reaction will remain dissolved in the oil, and the reaction mixture is cooled.  If difficulty is encountered in obtaining permanent suspension of the dehydrated hydroxide in the oil, a small amount of a free fatty acid, such as oleic, naphthenic or a mixture of oleic and naphthenic acids may be added to the oil-hydroxide mixture prior to dehydration.  The hot high molecular weight fatty acid is preferably added to the slurry of anhydrous hydroxide in the form of a solution in mineral lubricating oil, the acid being preferably stearic acid or hydrogenated fish oil acids although any of the acids customarily used in making oil-thickening soaps may be used.  Inhibitors such as phenyl-a -naphthylamine, crystallization modifiers such as zinc naphthenate, antioxidants and other additional ingredients can be incorporated in the grease if desired at the time the hot grease leaves the reactor. After reaction between the hydroxide and fatty acid, the reaction mixture may be blended continuously with an oil at essentially the same temperature, before cooling. In an example, the slurry of anhydrous hydroxide is prepared by mixing and heating together lithium hydroxide monohydrate, oleic acid and lubricating oil. Specifications 582,717 and 583,303 are referred to.
