Title: Apparatus for indicating in connection with the treatment of materials in a fulling machine or the like
IPC: D06C17/02
Filed: 1922-02-07
Abstract: 175,268. Hemmer Ges., L. P. Feb. 7, 1921, [Convention date]. Indicating; dials and scales; index hands and pointers.-Comprises indicating means for measuring the length of material under treatment, and the duration of the treatment, according to the revolutions of the machine in a frilling process or the like. A belt and pulley drives a worm e, which drives differential worm-wheels a, b. The wheel a is feathered on, and the wheel b loose on the plain part of a screwed spindle f on which works a nut h. The end of the spindle f carries a pointer i moving over a dial scale representing lengths. The nut h is driven by the rod g projecting from the wheel b and moves a slide l carrying a pointer m moving over a scale n representing hours. The pointer i may be adjusted to any part of the scale by pulling on a chain r on the release of which the pointer becomes once again fast with the spindle f. On a second slight pull on the chain the pointer returns to zero. The pointer m may be adjusted by sliding the wheel a against the influence of the spring p until disengaged with the worm e and then turning the spindle f . The dial k shown is graduated to represent 70 units of length on the outer circle and 60 on the inner circle. In operation, a piece of material of known length, say 60 units, is run through the machine. If the needle i is on the outer circle and indicates 65 units, the needle is telescoped until the 60 circle is reached. A similar adjustment of the needle m is made on the time scale which, as shown, is graduated for 6 hours at the top and for 4 hours at the bottom. When the pointer m is brought to zero a bellcrank q is moved to operate throw-off gear and, if desired, a signal.

Patent GB-810263-A (GB)
Title: Treatment of raney metal suspensions
IPC: B01J25/04
Filed: 1956-02-07
Abstract: Raney metal catalysts are recovered by treating an aqueous suspension of the finelydivided metal with a "polyelectrolyte" which causes the metal particles to agglomerate.  A polyelectrolyte is an organic polymer which in the presence of water forms organic ions.  The polymers have a substantially linear C chain, are of molecular weight at least 10,000, and are hydrophyllic due to the presence of side chains containing hydroxy, sulphonic, or carboxy groups.  Examples are described in U.S.A.  Specification 2,625,529 and include compounds made by polymerizing unsaturated carboxylic acids or their derivatives alone or with unsaturated hydrocarbons or their derivatives. Suitable acids are fumaric, crotonic, acrylic or itaconic acid, their salts esters or amides.  The copolymer may be ethylene, styrene or vinyl ether.  A polymer containing acetyl, or nitrile groups in the side chain may be hydrolysed to introduce COOH or OH groups, or polymers may be treated to introduce a sulphonic acid group.  In examples, an aqueous suspension of finely-divided nickel used in the hydrogenation of alcohol or acetone is treated with an aqueous solution containing a very small amount of the calcium salt of a copolymer of vinyl acetate with maleic acid. The nickel settles out in clumps within a few minutes and is readily filtered.  The recovered catalyst shows no loss of activity.  The process may also be applied to finely-divided suspensions of silver, cobalt, iron or copper.

Patent GB-712544-A (GB)
Title: Improvements in the recovery of acetylene with organic solvents
IPC: C07C7/11
Filed: 1952-02-14
Abstract: Acetylene is recovered from gas mixtures obtained in the high temperature decomposition or partial combustion of low molecular weight paraffin hydrocarbons by absorbing the acetylene with an organic solvent which has a boiling-point above that of water, is at least partly miscible with water and has selective absorption power for acetylene, releasing the acetylene from its solution in such solvent, recirculating said solvent, withdrawing from said circulation at least part of the solvent, diluting it with water, e.g. from the same amount to 6 or even more times its own volume, removing therefrom the precipitate formed and returning the solvent to the separating process.  The solvent may be subjected to a distillation to drive off a substantial part of the solvent before the dilution with water, e.g. from 50 to 95 per cent of the solvent may be driven off.  The distillation residue may be diluted with from half to three times its own volume of water. The liquid remaining after removal of the precipitate may be subjected to a distillation to obtain anhydrous solvent which is returned to the separating process, or the liquid itself remaining may be returned to the separating process.  The organic solvent may be an oxygen containing solvent, e.g. any of the aliphatic carbonyl compounds and their acetals, aliphatic ethers, in particular those containing in addition to the ether group a further hydrophilic group such as a hydroxy group or another ether group as in ethylene glycol mono alkyl ethers, carboxylic esters, in particular those containing hydrophilic groups in addition to the ester group either in the acid or in the alkyl radical, aliphatic lactones such as g -butyrolactone and its homologues, aliphatic carboxylic acid amides in particular those derived from alkylated amines such as dialkyl formamides, especially those containing alkyl radicals up to 4 carbon atoms, alkylated ureas, bis C1 to C4 dialkyl amides of dicarboxylic acids, and lactams such as pyrrolidone and its substitution products containing lower aliphatic hydrocarbon radicals on the nitrogen atom and homologues of such lactams.  One example is given. Specification 712,535 is referred to.

Title: Tdm telecommunications exchange systems
IPC: H04J14/08
Filed: 1973-01-26
Abstract: 1399664 Photo-electric apparatus SIEMENS A G 26 Jan 1973 [4 Feb 1972] 4008/73 Heading G 1 A [Also in Division H4] A t.d.m. telecommunications exchange system includes a switching network comprising first and second matrixes Ma1, Ma2 of light sensitive components, each of which components is assigned to respective transmission links e.g. Al, Am, first and second light deflectors LA1, LA2 arranged to direct first and second light beams on to selected ones, in each matrix, of the light-sensitive components so as to establish a connection between the associated links and the bus-bar Sa which is common to both matrixes. The light beams are not modulated with the signals transmitted via the busbar. Preferably, the bus-bar covers the matrix in the form of a plate. The matrixes may be spatially interlocked. In the system of Fig. 1 concentrated light beams are directed from source L to light modulators LM1, LM2 where they are modulated with channel marker information under the control of generator KM, so as to provide that deflectors LA1, LA2 select the required channels. The selection operates either by the light beams being scanned across the arrays of detectors and at the required detector being stopped and brightened up, or the general scan is too fast normally to provide sufficient illumination of a detector to effect switching but is stopped at the selected detector when switching is desired. The detectors may be photo-diodes or phototransistors and may provide the switches between bus-bar Sa and the assigned link. Alternatively, they may actuate further switches e.g. Tl<SP>1</SP>, Tm<SP>1</SP>. The system is applicable to PAM or PCM transmission; for the latter a plurality of networks may be provided. Resonance transmission may be provided by insertion of coils Lil or Lim in links Al, Am e.g. for PAM, and/or in bus-bars Sa, Sa<SP>1</SP>. Low pass filters TPI, TPm may be provided to demodulate PAM signals. Alternative apparatus is provided for PCM demodulation. To aid accurate selection i.e. by positional adjustment of the light deflectors, each detector of a matrix is associated with two or more e.g. four encircling, additional sensors. These can be connected in pairs to differential amplifiers which sense any misalignment of the beam from a detector., Figs. 2, 3 (not shown).
