Abstract: 1,156,184. Air humidifier. E. RUDSTROM. 23 Sept., 1966 [24 Sept., 1965], No. 42533/66. Heading B1R.  An electrode-type air humidifier has electrodes 14 and 17 suspended by springs 12 and 23 respectively from the lid 9 of a vessel 11 containing water in which the electrodes are immersed, the output of the humidifier being controlled by the raising or lowering of a member 18 which at its lower end serves as a screen betwen the electrodes and also has outwardly extending flanges 20 with recesses 21 in which springs 12 and 23 are located thereby serving to vary the distance between the electrodes as the member 18 and its flanges 20 is moved up and down. Movement of member 18 is effected by a control knob 1 fixed to a spindle 2 journalled in a portion 28 of the lid 9, the spindle 2 having an externally threaded extension 25 which engages in an internally threaded portion 19 of member 18, A ring 26 prevents linear movement of spindle 2 and its threaded extension 25 so that rotation of the spindle moves member 18 up or down. A second control knob 5 is rotatably mounted on spindle 2 below control 1 and by means of a lug 4 engaging in an arcuate groove 3 formed in the undersurface of control knob 1 and the arrangement gives control knob 5 a lost-motion link with control knob 1 and the member 18 controlling the electrode system. Control knob 5 is associated with a scale on a cover 7 showing degrees of hardness of water and as an initial adjustment of the humidifier control knob 5 is moved to the relevant number on the hardnss scale. As shown the electrodes are mounted in a container 13 secured to lid 9 and receiving water from vessel 11 through a hole 15.

Abstract: 936,124. Vocoders. MINISTER OF AVIATION. Dec. 18, 1961 [Dec. 30, 1960], No. 44730/60. Class 40 (4). In a formant tracker for an analysis synthesis telephone transmission system an adjustable network operates on the incoming speech and a signal is derived which is rectified and fed back to adjust the network continuously so that the network output is the original speech operated on by substantially the inverse of at least some of the formant forming filters of the vocal tract, whereby the signal derived is constrained to be representative of the corresponding formant parameter of the input speech signal. Fig. 1 shows a block diagram of a preferred embodiment for deriving tracking signals at O1 and 02, corresponding to the two lower formants of the speech input at I1, the tracking signals being amplified and fed back via I2 and I3 to control the characteristics of the network. It is shown mathematically that, assuming the speech signal can be represented as where p is the Heaviside operator, w 1  and w 2  are the two lower formant angular frequencies, and P 1 (t) is a function dependent on the excitation and other characteristics of the vocal tract, the output of adder S1, Fig. 1, will be (1+ap<SP>2</SP>)S(t), where a is the signal applied via input 12 to multiplier M1, (if a = 1/x 1 <SP>2</SP> this x 1 <SP>2</SP> function (1+ap<SP>2</SP>) is the inverse of the function which represents the effect of the formant angular frequency w 1  on the original speech and thus (1+ap<SP>2</SP>)S(t) will represent the speech signal with the component due to the formant w 1  removed. Similarly, the output of adder S2[= (1+ap<SP>2</SP>)] will represent the speech signal with the component due to formant w 2  removed. The output of adder S3 will be (1+abp<SP>4</SP>+ap<SP>2</SP>+ bp<SP>2</SP>)S(t) = (1+ap<SP>2</SP>)(1+bp<SP>2</SP>)S(t) and if a and b are correct (i.e. = 1/w 1 <SP>2</SP> and 1/w 2 <SP>2</SP> respectively) will   contain no components due to either formants w<SP>1</SP> 1  or w 2 , but if one of the formants say w 1 , is incorrectly tracked there will be an output from this adder S3 which will be in phase with the output from one of the adders, i.e. S2, and these signals applied to the inputs of phase-sensitive detector P2 will produce an output dependent in magnitude and direction on the difference 1 between a and +- which output, after integraw 1 <SP>2</SP> tion and amplification, is applied to input I2 to adjust the network to eliminate the formant corresponding to the angular frequency w 1  from the outputs of adders S3 and S1. A circuit is described with respect to Fig. 2 (not shown), incorporating compensation for the limitation of frequency response of practical differentiating networks.

Title: Binding agents for paints and varnishes
IPC: C09F7/00
Filed: 1965-10-22
Abstract: Binding agents for paints and varnishes are produced by heating a petroleum resin with a drying and/or semi-drying oil.  The petroleum resin is a thermoplastic resin obtained by polymerizing in the presence of a Friedel-Crafts catalyst either (i) a steam cracked petroleum distillate boiling in the range 30-280 DEG  C. or (ii) a mixture of olefines with sufficient diolefines to result in a resin rather than an oil or a rubbery material.  The petroleum resin may be derived by polymerizing in the presence of AlCl3 a light gasoline fraction made by steam-cracking a petroleum distillate.  The drying oil may be linseed oil.  The heating may be carried out at 280-310 DEG  C. under nitrogen and at 10-50 mm. Hg.  The binding agent may be formed into a paint by compounding with lithopone, TiO2, dolomite, white oil and lead and cobalt naphthenates.

Each filter sheet is divided into a filtration portion and a portion defining an attachment face to which the connecting member 4 is joined by adhesive, stitching, rivets or staples and the part 8 of the connecting member 4 which is spaced from the attachment faces interconnects only the boundary line between the attachment face and filtering portion of one sheet with the equivalent boundary line on the other sheet. The result of this is that the sheets can only be lowered into the filter press to the level of connecting portion 8 and thus, all of the connecting member is outside the press. The sheets I are suitably square or rectangular and the connecting member is suitably in the form of one or more strips of folded flexible material, e.g. plastics or woven fabric impregnated with rubber or plastics, applied only one edge of each sheet. Backing strips 11 may be provided at the attachment face. Alternatively, the connecting member may itself be foldd over the ends of the filter sheets to provide a backing or no backing may be used.
