Title: Improvements in or relating to radio telegraph communication systems
IPC: H04L1/04
Filed: 1947-08-07
Abstract: 654,253. Multiplex radio signaling. WESTERN ELECTRIC CO., Inc. Aug. 7, 1947, No. 21761. Convention date, Dec. 1, 1944. [Class 40 (v)] [Also in Group XL (b)] Multiplexed two - tone telegraph signals are simul. taneously transmitted as two discrete frequency bands; and at the receiver the frequencies of the signals in one band are shifted to a position in the spectrum which is nearer to, but still different from the signals in the other band, from each band the individual channels are selected, and applied to current limiters which select the stronger signal. At the transmitter, Fig. 1, each of the channels 1 ... 6 comprises a pair of oscillators, e.g. O11, 012, supplying mark and space tones respectively to sending circuits, e.g. SS11, SS12 and to band-pass filters, e.g. F11, F12. There is also a calling channel 023 &c. The oscillators each produce a different one of the odd harmonics of the base frequency oscillator Oo. The combined output of all channels is passed by a low-pass filter F31 to the transmitter RT; and is also passed via amplifier Al to a modulator MD where it is mixed with the output of oscillator 030, the lower side-band being selected by filter F32 to provide a transposed band of signals which are transmitted simultaneously from the transmitter RT. At the receiver, Fig. 2, the incoming signals are demodulated and amplified, the lower band of signals is selected by filter F39 and passed to channel-selecting narrow band-pass filters F41 ... F53. The transposed band of signals, selected by filter F40, is mixed at DM with the output of oscillator 041, which is of a higher frequency than the corresponding oscillator 030 at the transmitter so as to produce a band of frequencies which is nearer to but still distinct from the original. This band is passed by amplifier A4 to channelselecting filters F61 ... F73. In each channel, e.g. channel 1, the outputs from both bands are combined, amplified, and passed to a current limiter CL which discriminates in favour of the stronger signal. The output is passed by the appropriate filter of the set F81, F82, F91, F92, to a detector and telegraph printer. In a modified system, Figs. 3 and 4 (not shown), the multiplexed two-tone signals are transmitted and received as a pair of different frequency single side-bands as in Specification 516,088, one band of the received signals being, as before, applied directly to the channel-selecting filters ; the other band being transposed by the same amount as before by first mixing with oscillations of the same frequency as 030, Fig. 1, and then with oscillations of the same frequency as 041, Fig. 2. Specification 654,271 also is referred to.

Abstract: 281,030. Harris, H. K. Sept. 9, 1926. Monogrammic signs. -Relates to devices of the type in which the elements or surfaces are coated with or carry fluorescent, phosphorescent, or radio-active substances, and consists in combining such surfaces with a source of visible or invisible light so that the point of incidence of the light is movable relatively with respect to the surfaces or elements. The element or surface is preferably constructed of glass, porcelain &c. and is divided up by separating walls a into shallow cells b which hold the fluorescent substance. The element is closed with a cover d of glass, quartz, &c. A metal casing c may encircle the element and retain the parts in position by a spun over flange f. Large surfaces or plaques may be prepared and light projected on them through a slide screen or mask relatively immovable with respect to the surface during the existing action and in this manner letters, &c. may be produced. A beam of visible or invisible rays, ultra-violet or X-rays may be emitted from a projector which is movable according to a predetermined path. After the substance has been exposed and excited by light rays of a suitable wave length, and has been exhibited, its luminosity may be extinguished by exposing it to light of a different and selected wave length according to the substance used.

Title: Improvements in indicator mechanism for cash registers
IPC: G06C11/02
Filed: 1920-07-22
Abstract: 170,650. Haddan, A. J. H., (National Cash Register Co.). July 22, 1920. Cash registers; differentially-moved indicators. - In a cash register of the key or lever set crank-operated type, the actuating- means for the indicators are controlled by the main differential racks through a floating pinion which, in the operation of the machine, is returned to its central or zero position to give the indicators their new setting. The invention is shown in Fig. 2 as applied to the machine set forth in Specification 127,228 and 127,237 wherein vertically-slidable racks 71 are differentially positioned during the operation of the machine. Each indicator drum 120 is actuated by a rack 117 engaged by a floating pinion 112, which is carried by an arm 115 pivoted at 116, and also meshes with teeth 111 on the differential rack 71. At each operation of the machine, a hooked arm 125 is moved by the main shaft 36 to release a pin 127 on the arm 115 so that the pinion 112 may roll along the rack 117 as the rack 71 rises to its new setting. The latter rack is then held by a cam-controlled detent pin 135 and the hooked arm 125 returns and cams the pinionsupporting arm 115 to central position, thus effecting the new setting for the indicator rack 117. A similar mechanism is employed for positioning the prismatic transaction indicators 173. The flashes 141, 174 are controlled from the shaft 124 carrying the arms 125 and rocked by a camoperated connecting-rod from the main shaft 36. In Fig. 4 the invention is shown as applied to a lever-set, crank-operated machine, the principal modification being that the hooked arm 125 is normally out of range of the pinion 112 to permit its movement during the setting operation. The detent pin 212 similarly is normally out of engagement with the rack 71 and the indicator racks 117 are retained, when set, by cam-operated detents 204.

Title: Improvements in the manufacture of electric resistance elements
IPC: H01B1/00
Filed: 1935-08-02
Abstract: 460,895. Photographic sensitive materials ; developing. GAUT, G. C., HUGGINS, B. F., and PLESSEY CO., Ltd. Aug. 2, 1935, No. 22004. [Class 98 (ii)] [Also in Group XXXVI] An electric resistance element is made by exposing to light or other suitable electromagnetic radiation a film or surface containing a material such as silver bromide, iodide or chloride, in which is incorporated a suitable conductor in finely divided form or in the form of a suspension or dispersion, e.g. colloidal carbon, the silver bromide &c. being converted into an electrically conductive state by the exposure, the degree of reduction by exposure and development being controlled to adjust the ohmic value of the resistance. The film may be carried by a support of paper, celluloid, cellulose acetate, &c. or the support may be dispensed with, and by controlling the exposure by a stencil, optical wedge or the like the resistance element may be graded or its form controlled. The light sensitive compound preferably consists of a lacquer containing pyroxylin, silver nitrate, ammonium bromide, soot, ethyl, methyl and diacetone alcohols, ammoniacal ethyl alcohol, ether, acetone and triacetin in stated proportions to which resin and ester gum may be added, and the mixture is applied to the support and exposed to light from a mercury lamp through a suitably shaped mask which controls the graduation of the resistance, the value of which also depends upon the composition of the compound and the degree of exposure. The element is then passed through a bath of ammonium bromide in alcohol to prevent fogging, developed in pyrogallic acid in ammoniacal alcohol and fixed in ammonium thiocyanate in ammoniacal alcohol. The process is preferably made continuous by using the apparatus shown in Fig. 3. The support 13 of paper &c. is fed from a drum 14, through an emulsion bath 17 to the exposure drum 19, and thence through washing, developing, fixing, &c. tanks and a drying chamber 32 to cutting apparatus 36, which severs the strip 13 into sections, each constituting a resistance element of specified value. The mask which is preferably attached to the lamp chamber 20 may cause the exposure to vary transversely of the strip 13 so as to produce a resistance which varies logarithmically or otherwise across the strip. The edges of the strip, however, are fully exposed and form low-resistance contact portions. The resistance elements may be polished by a pad 34 before or after severing. Instead of a stencil or optical wedge, the degree of exposure may be controlled by varying the wavelength of the light falling on different parts of the band, in which case a beam of white light is passed through a quartz prism and the spectrum projected on to the band. Alternatively, in place of a separate mask a supporting band of varying opacity may be used.

Title: Improvements in or relating to sliding door operating mechanisms
IPC: E05F15/14
Filed: 1931-08-04
Abstract: 380,560. Door-operating mechanism. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of McCormick, H. V. ; 573, Lafayette Boulevard, Long Beach, New York, U.S.A.) Aug. 4, 1931, No. 22121. Convention date, Aug. 8, 1930. [Class 65 (i).] Operating mechanism for sliding doors comprises main toggle levers associated with, and effecting the movement of, the door, and auxiliary toggle levers associated with the main toggle levers and with a driving device in such a manner as to produce slow initial and final movements of the door, with quick intermediate movement. The mechanism may be applied to doors having separately moving panels, being arranged so that the different panels take the same time for their movements. The apparatus is preferably operated by a screw mechanism, driven by an electric motor, in which one of the screw members is directly connected to the auxiliary toggle linkage, and the motor is hingedly mounted to prevent binding between the screw and nut. As shown, the screw mechanism is placed vertically at the side of the door, and operates through levers pivoted to the door frame. The nut 44 is rigidly connected by a tube 42 to the shaft of the motor 21, which is hinged to a fixing bracket at its lower end. The tube 42 serves as a cover for the screw, and the nut also carries a cover tube 39 having bushings at its ends for the screw shalt 47. The screw shaft 47 is pivoted at its upper end to an auxiliary toggle lever 49 pivoted to the door frame, but is not capable of rotation about its axis. The lever 49 is connected by a toggle link 51 to a similarly-pivoted lever 7 by which the door is operated through lever 8 and link 9. The arrangement of levers is such that the door will start and stop slowly, with relatively rapid intermediate movement, and the two panels of the door move simultaneously to overlapping open positions ; also, the ends of the link 51 do not quite come into line with the pivot of lever 49 when the door is open, so that the door may be closed by hand. In order to retain the door open against the gravity effect of the mechanism, but not against the closing force of the motor, a roller 59 is provided on the side of the lever 49 to engage a spring-controlled detent 60 pivoted on the door frame. Specification 364,846 is referred to.

Title: Improvements relating to flexible pocket receptacles
IPC: A45C1/06
Filed: 1934-07-30
Abstract: 440,047. Note cases &c. BUXTON, W. R., 826, Longmeadow Street, Longmeadow, Massachusetts, U.S.A. July 30, 1934, No. 22166. Convention date, Aug. 22, 1933. [Class 18] A note-case &c. is made from the two blanks shown in Figs. 4 and 5, the blank 23 being laid on section 20 with ears 29 engaging slots 28, flaps 25 being then folded over on lines 26, and the front 15 being folded on line 19, the whole being secured by tongues 22 on end flaps 17 which engage slits 21. The pocket for notes is constituted at the front by section 15 and at the back by sections 23 and 25, the section 23 sliding when the case is folded about line 16 taking the innermost note with it owing to the fact that the area of the note which is in contact with the slidable section 23 is larger than the area in contact with the fixed flaps 25. Buckling of the section 23 and of the notes is thus prevented. A partition may be secured in the pocket for notes by stitching a flap to the bottom edge of section 23, and the end edges of flaps 25 may be stitched between the ends of the outer wall and the outer ends of flaps 20. An alternative form of wallet is shown in Fig. 8 which is substantially as wide as it is long, sections 31 which correspond to sections 20, Fig. 4, and sections 32 which correspond to sections 17, Fig. 4, being of the shapes shown the inclined edges of the flaps which correspond to flaps 25, Fig. 4, being shown at 36, these flaps being secured by stitching. Projections 37 correspond to projections 29. Specification 315,703, [Class 18], is referred to.

Abstract: 798,119. Pressure exchangers. BROWN, BOVERI & CIE. AKT.-GES. July 29, 1954 [July 29, 1953], No. 22170/54. Class 8(1). In a pressure exchanger the pressures of the gas at the high pressure stage may be unequal and the pressures of the gas at the low pressure stage may also be unequal. A pressure wave generated at one end of the cell always reaches the other end of the cell at the latest when that cell either becomes open to or is closed by a controlling opening for the gas relative to which the cell is movable. As shown in Fig. 2, opening of a cell to duct In in which a lower pressure exists generates a wave of rarefaction 1 which reaches the opposite end of the cell as it opens to duct 1v. Depending on the pressure in 1v a wave of rarefaction or compression 2 is generated and gas flows into the cell from 1v when the wave 2 reaches the other end of the cell, the cell is closed to the port 1n and a compression wave 35 generated and when wave 3 reaches the opposite end of the cell it is closed to duct 1v. Opening the cell to duct 2v in which a higher pressure exists causes a compression wave 4 which is followed by a rarefaction or compression wave 5, depending on the pressure in duct 2n, and outflow from the cells to the duct 2n occurs. Wave 5 is followed by a rarefaction wave 6. Duct 2n may open before duct 2v or duct 1v may open before duct 1n. The ducts 2v, 2n may be arranged on the opposite sides of the cell ring to those shown. The length of the casing sections d-d<SP>1</SP>, h-h<SP>1</SP>, e-el, i-i<SP>1</SP> may be reduced to practically zero. An additional gas inlet duct may communicate with the cells between the ducts 1, 2.
