Title: A method and apparatus for transmitting a speech signal
IPC: G10L19/02
Filed: 1963-05-22
Abstract: 991, 994. Selective signalling. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 22, 1963 [May 24, 1962], No. 20310/63. Heading G4H. [Also in Division H41 A pulse code modulation system for transmitting the excitation pulse spacing in a channel vocoder system (see Division H4) comprises Fig.7  a binary counter 11 which counts pulses from a source of quantizing pulses 14, the pulses being gated into the counter by a pulse from a source 15 whose pulse repetition frequency is equal to the lowest excitation frequency expected, e.g. 150 cps. The counter counts pulses from the source 15, at e.g. 15 kc/s, until an excitation pulse arrives to close gate 12. The resulting number stored in counter 11 is passed, on occurrence of the following pulse from source 15, into a shift register 17 so that the parallel stored binary number is serially transmitted over the line 20, the counter 11 being reset by the pulse from source 15 after a suitable delay provided by circuit 18. At the receiver a shift register 24 receives the P.C.M. signal and when the register is full the signal is transferred into the counter 27 to set the counter to the complement of the count in the counter in the transmitter. The counter 27 then counts the quantizing pulses from source 26 until the full count is reached when a pulse is generated which is passed for shaping to shaper 31 to form the excitation pulse for the receiver.

Title: Improvements in or relating to electrical storage apparatus
Inventor: BANNISTER LAWRENCE HENRY
IPC: G11C19/20
Filed: 1948-07-31
Abstract: 647,030. Pulse-storing circuits. MINISTER OF SUPPLY. July 31, 1948, No. 20440. [Class 40 (vi)] Apparatus for storing information comprises a chain of electronic trigger circuits, each having a number of stable states and each of which may be set initially to a state indicative of one unit of information or to a datum state. A trigger pulse is fed in common to all the trigger circuits to revert them to the datum state, each circuit after the termination of each trigger pulse then taking up the state occupied prior to the trigger pulse by the previous circuit of the sequence if that state differs from the datum state. The figure shows a storage system comprising trigger pair circuits V1a; V1b; V2a; V2b; &c. which may be connected in a closed ring. In the datum state the left-hand valve of each pair is cut-off and the right-hand valve conducting. Information is set into any trigger pair by changing its state to that in which the left-hand valve is conducting and the right-hand valve cut-off by moving the associated switch S to connect the anodes of diodes D1b D2b, &c. to positive potentials and then returning them to earth. Each trigger pair is reverted to the datum state by the application of a large negative going pulse to the suppressor grid of each left-hand valve via the terminal " Trigger." If, for example, information has been stored in the first trigger pair so that valve V1a is conducting and V1b cut-off, then on occurrence of the trigger pulse this pair reverts to normal but the pulse is arranged to terminate and the grid of V2a to re-attain its common cathode potential before the anode of V1a has become fully positive so that the grid of V2a is still positive and the second trigger pair changes over to the " information stored state. Before the suppressor grid of V1a has re-attained the common cathode potential the anode of V1a has become sufficiently positive to ensure that V1b is fully conductive and the first pair thus reverts to the datum state. Thus after the termination of each trigger pulse information units which may be stored in a number of pairs simultaneously are progressed one pair to the right in the sequence. The information may be extracted from the end of the chains or from any or all of the anode circuits of valves V1b, V2b, &c. The diodes- D1a, D2a, &c. prevent the suppressor grids of the left-hand valves from rising above cathode' potential. The rate of fall of grid potential of valves V1a, V2a &c. is made large by returning their grid leads to a negative potential, and diodes D1b, D2b, &c. prevent their grid potentials from falling below that of earth.

Title: Improvements in or relating to synthetic linear polyamide filaments
IPC: D01F6/60
Filed: 1944-10-23
Abstract: Synthetic linear polyamide filaments which contain a compatible phenol-formaldehyde resin are subjected to the action of a hot aqueous alkali solution while held at fixed length.  The extraction of the resin by paint and lacquer solvents is thereby reduced and the bend-recovery of the filaments improved.  The preferred phenolic resins are those of low molecular weight which do not become infusible on heating for short periods at 275 DEG  to 285 DEG  C. and which are obtained by the acid condensation of formaldehyde and unsubstituted phenol in molecular ratio of from 0.5 to 1.0.  Ortho- and para-substituted phenols may be used, and in general the ratio of formaldehyde to phenol must be decreased with increase in molecular weight of phenols in order to maintain compatability with the polyamides.  For example, there may be used a resin prepared from formaldehyde and p-tertiary-butyl phenol in molecular ratio of 0.75, or a resin prepared from formaldehyde and p-octyl phenol in molecular ratio of 0.5.  Other suitable substituted phenols are cresol, amyl phenol and phenyl phenol. Suitable aqueous alkali solutions are solutions of hydroxides of sodium, barium, potassium and lithium, and salts of weak acids such as sodium carbonate and sodium acetate.  In an example, a drawn filament containing 20 parts of phenol-formaldehyde resin (prepared by condensing 900 parts of phenol with 580 parts of 37 per cent formaldehyde solution in the presence of 9 parts of ammonium chloride and 10 parts of oxalic acid) and 80 parts of polyhexamethylene adipamide is wrapped around a reel and exposed to boiling water for an hour.  It is then immersed in a boiling solution of 5 per cent sodium hydroxide for one hour. Specifications 461,236, 461,237 and 27108/39 (as open to inspection under Sect. 91) are referred to.

Abstract: 885,818. Recovering chlorine from brine, electrolytically. IMPERIAL CHEMICAL INDUSTRIES Ltd. June 10, 1959 [June 27, 1958], No. 20672/58. Class 41. Chlorine is recovered from brine solution containing free chlorine by electrolysis using a voltage below that at which hydrogen is generated at the cathode, e.g. 2 to 2.4 volts. A brine effluent from an electrolytic cell using a mercury cathode to remove sodium metal may be used when traces of mercury and compounds thereof are also removed. The process may also be applied to the recovery of chlorine from gases low in chlorine content, by absorbing the gas in brine and then treating by the electrolytic process to recover chlorine in concentrated form. A brine effluent is fed through a pipe 8, Fig. 1, into the cathode compartment of a cell 1 filled with steel wool 6, and containing a porous pot 3 and graphite anode 5. Chlorine gas passes out of the anode compartment through a tube 10, and dechlorinated brine through an anolyte bleed 9. Mercury particles are trapped and retained on the steel wool. A voltage of 2 to 2.5 volts is applied. The apparatus may be modified whereby the brine is fed first into the anode cell. The electrodes used may be inert to brine and chlorine or attackable by them, e.g. graphite, platinum, titanium plated with platinum, or steel, mercury or mercury amalgam respectively. The porous pot diaphragm may be replaced by asbestos sheet, and the asbestos sheet may be attached to a foraminous steel or titanium metal sheet on the reverse side of which is a platinum coating, thus forming a diaphragm supported on an electrode.

[Class 120 (ii).] In a winding-frame having an endless conveyer carrying supply bobbins to positions facing the creel spindles or pegs with means for causing a relative movement between the conveyer and spindles to cause the bobbins to be placed on the spindles and with means for automatically doffing the empty bobbins, the spindles and conveyer are given a relative vertical movement before and after the donning operation so that they are placed at different levels and the conveyer moves along the bank of spindles beneath the latter ; the width of the machine is thus reduced and bobbin carriers of ample length can be used. As shown in Figs. 1, 3 and 5, the endless conveyer 1 carrying the bobbin carriers or cradles 4 is guided in a frame 2 mounted by rollers 10 on rails 11 disposed transversely of the bank of spindles which are carried by holders 7 on a rotatable shaft 12 supported in bearings fixed to vertical rods 14 slidable in bearings 15 fixed to the machine frame. The rods 14 rest on cams 16 fixed to a rotatable shaft 17 carrying cranks 21 connected by links 22 with the frame 2 and, when the conveyer stops with the cradles 4 and bobbins 5 in front of the spindles, the shaft 17 is rotated by a handle, or automatically, to cause the cranks 21 to move the frame 2 away from the spindles, Fig. 1, and the cams 16 to lower the spindle holders so that the front horizontal spindles are in line with the bobbins 5 ; the cranks 21 then pull the frame 2 towards the spindles so that the adjustable bar 6 on the frame pushes the bobbins on to the spindles while guided by the cradles 4, Fig. 3, and finally the spindles are again raised and the frame moved under them for further movement of the conveyer. In modifications the spindle holders are stationary and the frame is given a vertical movement in addition to its transverse movement either by cams on the shaft 17 and on a parallel shaft geared thereto or by cam-shaped guiding rails on which rollers on the frame run. The automatic doffing of the empty bobbins may be effected by the means described in the parent Specification.
