Title: Venetian blinds
IPC: E06B9/303
Filed: 1959-10-19
Abstract: 865,385. Venetian blinds. BENNETT, J. F. Oct. 19, 1959, No. 3518/59. Class 20(3) In a venetian blind front and rear pairs of slat-tilting cords 19, 20, and 22, 23 Figs 2 and 3, are also used for varying the position of the slat assembly. As shown in Fig. 3, the tilting cords 19, 20 secured to top slat 4 at the slat suspending front tapes 5a, Fig. 2, are guided over a pulley 31 in the head bar 2 and pass downwardly through the hole 33 in the head bar 2 and likewise the tilting cords 22, 23 pass over a pulley 32 and downwardly through the hole 33, the free ends of the respective pairs of tilting cords being joined together. The pulleys 31, 32 are geared together by gear wheels 33, 34, Fig. 3, normally to rotate the pulleys oppositely but by pulling the free ends of all the tilting cords together inwardly across the windows, cords 19, 22 of the pairs causing the pulley 31 and its gear wheel 34 to move in the preferably inclined bearing slot 39 away from the pulley 32 and its gear wheel 35 so that the slat assembly can be raised or lowered as a whole. On allowing the cords to hang freely the pulley 31 and gear 34 return under gravity for the gears 34 and 35 to engage whereupon the pairs of front or back tilting cords may be used individually to tilt the slats. In the construction shown in Fig. 6 the pulleys and their gear wheels are rotatable on a shaft 37a and coupled to rotate in opposite directions for tilting the slats by an idler wheel 36 mounted on a spring biased shaft 44 adapted to be moved against the spring 47 through the action of a loop 43 on the shaft engaging and pivoting on the bottom edge of an opening 45 when rocked by a lever 41 pivoted on the shaft 37a on engagement against a pin 42 thereon by the tilting cords 23 &c. when pulled across the window. The lever 41 may also be manipulated by a separate cord 48. In another construction (Figs. 7, 8 not shown) the cords when pulled across the window operate a lever to disengage pressure rollers operating on the cords passing on diametrically opposite sides of a sheared pulley to enable the cords to move together in the same direction for lifting or lowering the assembly. In Fig. 9 gear wheels 73, 74 engaging the pairs of cords 19, 20, and 22, 23 passing over pulleys 70, 71 are coupled by a crown wheel 80 mounted on a lever 78 pivoted above the shaft 75 of the wheels 73, 74 and is operated against springs 81 to disengage the crown wheel by the tilting cords contacting a cross bar 82 on the lever when pulled across the windows. The raising and lowering cords 7, 8 Figs. 2 and 3 operate on the lower cross bar 3, Fig. 2 and are retained in adjusted position by a catch.

Title: Improvements in or relating to radio signalling systems
IPC: H04B14/00
Filed: 1929-11-19
Abstract: 339,459. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Beverage, H. H.). Nov. 19, 1928, [Convention date]. Fading, preventing; thermionic generators and modulating systems; thermionic amplifiers.- To eliminate the effects of fading, the transmitter carrier wave is frequencymodulated, the volume at the receiver being varied inversely in accord. ance with received signal intensity. Fig. 1 shows a tone signal transmitter 2 transmitting marking and spacing waves of slightly different fre. quency, effected by keying a portion of the inductance 5 or varying the capacity of condenser 24. The receiving amplifier comprises screened high frequency amplifiers 32, 42, equally responsive to both transmitted frequencies, a detector stage 40 and low pass filter 44 the circuit being completed through a resistance 46 the drop across which adds more or less negative bias to the grids of the valves of amplifier 32, normally biassed by a battery 54, in accordance with the received signal intensity, so that the amplification is a maximum with weak signals. The receiver proper, 60, is preferably connected between the amplifiers 32, 42 and discriminates between marking and spacing frequencies, either by being tuned to one or by having circuits tuned to each and actuating a recording pin in opposite directions. Fig. 2 shows a transmitter in which output from a microphone 102 or code signalling means 112, 114. is fed through the transformer 116 to a pair of oscillators 122, 128, the input circuits 124, 130 of which are respectively tuned to the two extremes of the desired frequency range so that the common forced oscillation frequency, due to the common anode coil 126, lies between the two resonant frequencies, its magnitude depending on the relative potential applied to the oscillator grids. The output from the system is made to modulate a constant frequency crystalcontrolled oscillator 140, the carrier is suppressed by the balanced modulator 150 and one sideband is eliminated in a filter 154, the resultant being amplified at 156 and radiated. Fig. 3 shows a receiver having an amplifier 162, detector 164 and local oscillator 166, and intermediate frequency amplifier 168, part of the output from which is passed through a band pass filter 170 to a detector 172, filter circuit 176 and biassing resistance 178 which acts similarly to the volume control resistance 46 of Fig. 1, the condenser 182 determining the time constant of the control action. The output from amplifier 168 is passed to a detector 190 through a circuit 188 tuned to one extreme of the frequency range thus transforming the frequency modulation into amplitude modulation. The output circuit may feed a loud speaker if speech is transmitted, or filters 196 and utilizers 198 in the case of multiplex code signals.

Title: Improvements relating to gas-concentration meters
IPC: G01J3/42
Filed: 1955-12-09
Abstract: 785,405. Infra-red testing arrangements. ETABLISSEMENTS J. TURCK. Dec. 9, 1955 [Dec. 10, 1954], No. 35469/55. Class 40 (3). An infra-red gas concentration meter comprises means for selecting a particular narrow band of frequencies in the infra-red spectrum and means for determining the amount of energy in this band absorbed by the test sample which utilizes the comparison of the remaining energy with energy passed through a reference channel containing a variable attenuator. The attenuator is adjusted until the energy received at the ends of the test and reference channels is equal and from its reading the amount of the gas present can be determined. In one embodiment energy from a wide-band infra-red source is directed to fall in a parallel beam on a plane diffraction system. The narrow band of frequencies additively reflected by the diffraction system are directed as shown at X-X (to the right of Fig. 2) to a lens L1, once more giving a parallel beam. Part of the beam passes through absorption chamber C to lens L2 and part is directed by mirrors M3, M4, M5, M6 in a second, reference, path which may include a second chamber similar to the first but filled with a gas transparent to infra-red radiation. This reference path includes an attenuator A. By means of a shutter disc energy is directed alternately through the chamber C and the reference path. Initially with the chamber C free of any absorbent substance the zero of the attenuator is adjusted until there is no A.C. output from the radiation sensitive device D on which is similarly directed energy passing through the two channels. When the chamber C is filled with the gas to be tested the attenuator is again adjusted to give no A.C. output from the device D. For any given gas the attenuator may be calibrated directly in concentration. Angular adjustment of the position of the diffraction system may be used to alter the frequency of the radiation to the absorption band of a different gas or substance and the apparatus then used for that substance. The concentration scale on the attenuator, correct for the first substance, will however require modification by a correction function.
