Abstract: 154,998. Zimmerman, O., and Weyel, H. Sept. 5, 1919. Gravity, materials descending by.-In a drying apparatus having a pair of shafts through which vegetable or other material is fed continuously, the drying medium being passed repeatedly through different portions of the material to and from chambers arranged one between and one at each side of the shafts, the drying-medium is passed through the lower parts of the shafts into the outer chambers, reheated or mixed with heated gas and passed back through the upper parts of the shafts to the middle chamber. In the apparatus shown in Fig. 1, material is fed from hoppers T to a pair of shafts S having perforated sides, and is discharged by drums 22 partitioned radially and operated by external hand levers. The air chamber between the shafts is divided into a lower compartment H and an upper compartment A'. Air is forced through a heater into the lower compartment, passes through the material in the shafts into outer chambers K wherein it is heated by steam-pipes R' and passes back through the material into the upper chamber A<1> and to atmosphere. Alternatively, cold air may be supplied to the lower compartment, whereby the dried material is cooled before its discharge. Figs. 4 and 8 shows a plant wherein gases from a furnace 7 after depositing solid matters in a chamber 8 flow in part through a damper-controlled pipe 10, wherein they are mixed with a proportion of air entering by a damper 12, into the lower compartment 4 of a double-shaft drier with perforated walls, and thence through the material into the outer chambers 6 of the drier, where they are mixed with and heated by furnace gases entering by a dampered pipe 11 having a damper 13 for regulated admission of fresh air, and pass back through the material into the upper compartment. Adjustable baffle-plates 18, 19 in the chambers 6 regulate the admission and mixture of gases. In a modification, the gases from the pipe 11 pass into perforated pipes within mixing boxes in the chambers 6. In a further modification, the drying shafts are provided with rotatable flaps about half-way down. so that only their upper halves may be filled with material at starting.

Abstract: 1312868 Photo-electric examination SIEMENS AG and CARL ZEISS-STIFTUNG [trading as CARL ZEISS] 19 April 1971 [20 Jan 1970] 21951/71 Heading G1A [Also in Division H4] A device for selecting and displaying specified portions of a scanned image is provided with an adjustable amplitude discriminator which allows the display of the specified portions of the image and causes the blanking out of the remaining portions of the image. In a first embodiment, Fig. 1 (not shown), a video signal from a camera (1) is applied to two adjustable amplitude discriminators (3, 4) the outputs of which are combined by a gate (5) which controls an electronic switch (6), when the amplitude of the video signal is between the threshold levels of the discriminators the electronic switch (6) passes the video signal to the display unit (8) but when its amplitude is outside these levels the elctronic switch connects the input of the display unit (8) to a potentiometer (7) by means of which the background level can be set as desired to black, white, or any intermediate grey level.. If desired only one discriminator may be utilized. In a modification, Fig. 3 (not shown), the  outputs of the threshold detectors (3, 4) are gated and applied to adjustable delay lines (11, 12) which provide the triggering inputs to a bistable stage which is prepared by the outputs of the gates. By suitably selecting the delays applied to the leading and trailing edges of the pulses three modes of operation are possible. In the first mode the leading edges only are delayed and features shorter than a selected length are suppressed, in the second mode the trailing edges only are delayed and features spaced by less than a selected distance are lumped together for cluster counting, and in the third mode both the leading and trailing edges are delayed and features shorter than a selected length are suppressed and those spaced by less than a selected length are lumped. A grey wedge scale may be arranged at the edge of the field of view of the camera or may be electronically generated and keyed into the video signal produced by the camera.

Abstract: 671,906. Rectifying. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 7, 1950 [Sept. 9, 1949], No. 22077/50. Class 38 (ii). In a converting system in which electric discharge apparatus is fed from a polyphase supply, to provide time for the apparatus to partially deionize and reduce the probability of arc-back, the current curve at commutation is flattened by reactors each having a linear part connected in series with a primary winding of the main transformer, and a self-saturating part so connected that it carries part of the current of another primary winding of that transformer. In Fig. 1 the main primary windings 5, 6, 7 of a transformer which supply a D.C. line 1, 2 through rectifying ignitions such as 15, each in series with linear parts 27 of inductors, are connected in delta to a threephase supply 3, and self-saturating parts 28 of the inductors are connected in the line connections to the delta. The line current leads the phase current by 30 degrees so that parts 28 desaturate and flatten the current curve a short time before it reaches zero and a low value of anode current is maintained just before the application of reverse voltage across each ignitor. In a modification, the transformer primary windings in series with the linear part of the inductors are connected in Y and the self-saturating parts are connected in delta, Fig. 2 (not shown).

Abstract: 1,207,634. Tape cassette apparatus. MOTOROLA Inc. 1 May, 1969 [21 May, 1968], No. 22311/69. Heading G5R. A converter cartridge, enabling one type of cassette to be played in a machine designed for use with a different type of cassette, contains transport apparatus to drive the tape of a cassette inserted therein and is formed for reception in the machine. Operation.-A twin spool cassette is loaded over spindles 51b, 52b and capstan 62 of the converter, Fig. 5, and the assembly loaded into the receptacle of an endless 4- or 8-track cassette player. On loading, roller 7 in the machine shifts cam 20 to operate slide 40 and thereby slide 49 to automatically begin playing. Slide 40 makes contacts 41, 42 to energize amplifier 31 which is fed with signals from converter head 30 and which feeds a magnetic field generator (32, Fig. 4, not shown), cooperating with the machine head. Concurrently, pin 48 on slide 49 is released from engagement with wire spring 95, Fig. 8, on brake member 93 having shoes 96, 97 normally held against the spool spindles; a roller 145 on slide 49 draws slide-plate 110 inwards to swing pinch roller 75 toward capstan 62 and head 30 against the tape, and to allow pin 114, operating in cam slot 115, to move leftwards, thereby engaging roller 65 with spool spindle 52b, roller 65 being coaxial with an identical roller (71) engaged with a further roller 64 driven by a belt 61 connecting pinch roller 60 and capstan 62. The tape continues to play until power to the machine is interrupted, where - upon the converter is ejected (not detailed) and the mechanism returned to the rest state of Fig. 5. A microphone (33) and oscillator (34) are provided in the converter for recording. Rewind is effected by depressing button 23 to press lever 155, Fig. 21, inwards. The lever 155 is pivoted at 151 to slide 49 and at 156 to pivotal arm 157 such that, on initial movement, roller 145 moves slide 49 and plate 110 outwardly to disengage the head 30 and pinch roller 75 and to apply the spool brakes. .On further movement, the roller 145 enters the left-hand enlargement of the cam slot 173 so that plate 110 is not moved further, but slide 49 is both rotated and moved inwards to release the brakes and pivot a bracket carrying a pair of meshing rollers (outlined in Fig. 8) so that the smaller engages the flywheel 63 and the larger engages spool spindle 51b. Upon release of the button, the above sequence is reversed and normal play continues after a temporary application of the brakes. If desired, the other button 22 may be pressed to latch the first in rewind, both buttons being released upon slight depression of the first 23 (Fig. 11, not shown). Forward wind is effected in a similar manner by depressing button 22 to engage the larger roller on the pivotal bracket with the flywheel 63 and spool spindle 52b, with the option of latching it by depressing button 23 as above.

Title: Improvements relating to cation-exchange processes and to the manufacture of materials for use therein
IPC: B01J39/07
Filed: 1945-08-30
Abstract: A cation-exchange material in the form of a resinous gel containing acetic acid radicles is prepared by causing mono-, di-, or tri-chloracetic acid or salts thereof to react in alkaline solution with either the constituents of a phenolaldehyde resin or an intermediate condensation product of a phenol, e.g. phenol, cresol, tannins (e.g. quebracho, mimosa or gambier tannins), or pyrogallol, and an aldehyde, e.g. formaldehyde or its polymers, acetaldehyde, benzaldehyde, or furfural, until gel formation occurs and the gel is then dried at a temperature between 100 DEG  C. and 180 DEG  C.  The use of xylenols and naphthol is excluded. Cellulose or starch may be incorporated.  As an example a resin was prepared from phenol and formalin heated to 100 DEG  C. for half an hour in the presence of caustic soda.  The resin was then dissolved in water containing caustic soda and chloracetic acid was added.  The solution was boiled for half an hour and paraformaldehyde was then added.  On evaporation a gel was formed which was dried at 150 DEG  C. and then ground to a size between 16 and 44 mesh.  The resin was then treated with dilute hydrochloric acid and washed.  Other examples are given using pyrogallol, tannin or phenol and tannin.ALSO:In a method of exchanging the cations of weak-acid salts in water or other liquid, in particular removing temporary hardness from water, a cation-exchange material in the form of a resinous gel containing acetic acid radicles is used.  The gel may be prepared (see Group I) by causing chloracetic acid or a salt thereof to react in alkaline solution with either the constituents of a phenolaldehyde resin or an intermediate condensation product of a phenol and an aldehyde until gel formation occurs and the gel is then dried at a temperature between 100 DEG  C. and 180 DEG  C.  Tannins, in particular quebracho, mimosa and gambier tannins, may be substituted wholly for the phenols.  Cellulose or starch may be incorporated.
