Title: Data processing arrangements
IPC: G06F3/06
Filed: 1970-06-08
Abstract: 1312977 Recording and playback RICOH KK 8 June 1970 [18 June 1969] 27518/70 Heading G5R A data processor has a device reading a magnetic tape carrying digitally coded signals recorded alternately with second signals supplying information to an operation, and has a switching circuit supplying the digital signals to the processing equipment and the second signals to a warning device which supplies the operator with information in dependence on the second signals. The second signals may be audio signals which are fed to a loudspeaker and which supply spoken instructions to the operator. The digital signals may be fed via a shift register and a decoder to a typewriter and are followed by coded function signals operating the switching circuit. A signal of frequency 800 Hz may follow the audio signal to automatically operate a switch to supply digital data to the registers or the 800 Hz frequency may produce a signal warning the operator to close the switch.

Title: Improvements in and relating to textile filaments and fabrics formed of cellulosic material
IPC: C08B3/10
Filed: 1929-09-10
Abstract: Textile filaments, fabrics, and other coherent structures, are subjected to the action of higher fatty acid chlorides in association with pyridine under conditions whereby esterification p  of the cellulosic material is effected to an extent insufficient to destroy the essential or primary physical character of the structure.  A textile fabric so treated is resistant to the action of water, and if the weave is sufficiently dense, it may become completely waterproof. The process is applicable to material made from natural or artificial cellulose fibres.  Artificial filaments may be treated during the course of their manufacture. In an example, cotton ribbon cloth, such as is used for making typewriter ribbons, is introduced into a mixture of stearyl chloride, pyridine, and chlorbenzene and heated at 100 DEG  C. for 30 minutes.  The cloth is then washed with benzene and dried. Palmityl, lauryl, or oleyl chloride may be used instead of stearyl chloride.  The acid chloride and pyridine may be mixed in equivalent proportions to form a complex compound which is applied as a pasty mass to the fabric.  In order to avoid destruction or weakening of the fabric the treatment must not be unduly prolonged, since weakening is observed, even when no esterification occurs, when the material is heated for several hours in presence of pyridine with the acid chloride much diluted with xylol.  It is desirable to carry out the treatment in the absence of air or oxygen.  It may be carried out as a continuous process, the fabric passing through a bath of the higher fatty acid chloride, then through a bath of pyridine, and then through a heated chamber the dimensions of which are such that the passage of the fabric occupies from 15 to 30 minutes.  The fabric is then passed through a bath of alcohol or benzol and dried.  Other yarns of fabrics which are not harmfully affected in the treatment may be mixed with the cellulose material and treated with it.

Title: An improved method and apparatus for heating gas streams
IPC: F28C3/02
Filed: 1939-10-09
Abstract: 535,482. Heating gases. GAS LIGHT & COKE CO., SILVER, L., and MACCORMAC, M. Oct. 9. 1939, No. 27549. [Class 64 (i)] A stream of combustible gas flowing through a casing 10 from an inlet 11 to an outlet 12 is heated by drawing part of the main stream through a nozzle 19 by air supplied under pressure through a pipe 17, burning the mixture and returning the hot gases to the main stream. An electrical ignition device 32 is withdrawn after combustion has been started. The quantity of gas withdrawn is regulated by adjusting the distance of a nozzle 18 on the air supply pipe from the contraction of the nozzle 19. The combustion chamber may be arranged outside the casing, and the nozzle 18 may project into a combustion chamber which is provided with apertures for the entrance of gas withdrawn from the stream.

Title: Bistable multivibrator circuit
IPC: H03K3/45
Filed: 1960-08-09
Abstract: 953,186. Transistor bi-stable circuits; circuits employing bi-stable magnetic elements. HASLER A.G. Aug. 9, 1960 [Aug. 11, 1959], No. 27563/60. Headings H3B and H3T. [Also in Division G4] A trigger pair comprises two transistors 1, 2, Fig. 1, having cross-connected base and collector electrodes, each collector circuit extending to a control winding 5, 6 on a respective magnetic storage core 3, 4 having separate output windings 9, 10 and linked input windings 7, 8. The input windings have twice the number of turns and act in the opposite magnetizing sense to the respective control windings. Initially one transistor only is conductive and the cores are magnetized in opposite senses. When an input pulse Io is applied to windings 7 and 8, both cores are brought to the same magnetic state and an output pulse is induced in a winding 9 or 10 by the switched core. This raises the base potential of the conductive transistor which ceases conduction, and the lack of potential drop across the associated collector resistor 17 or 18 causes a lowering of base potential of the other transistor which therefore becomes conductive. The collector current through the associated control winding switches the respective storage core when the input pulse terminates. The original condition of the circuit is again achieved when the next input pulse is applied. An application to binary counting is described, Fig. 2, in which trigger pairs 2<SP>0</SP>-2<SP>3</SP> are provided and counting takes place from left to right. In this arrangement the control winding 5 of each trigger pair is connected directly to a collector potential source Uc, while the control windings 6 are connected to this source by way of the input windings of all the succeeding trigger pairs. Counting selectively in either direction may be effected by the modification in Fig. 4 in which each pair of cores of a trigger stage is duplicated. By closing a switch 21 for left to right counting, or switch 121 for the opposite direction, one of the two core pairs 3, 4 or 103, 104 of each trigger is brought into use by completion of the output winding circuit, the two core pairs being arranged so that either their control windings 5, 105 or 6, 106 are connected directly to the source Uc by way of the input windings of the core pairs not in use at that time.

Title: Improvements in centrifugal bowl provided with sludge valves
IPC: B04B1/18
Filed: 1934-09-26
Abstract: 423,162. Centrifugal machines. AKTIEBOLAGET SEPARATOR-NOBEL, 8, Fleminggatan, Stockholm.-(Assignees of Strezynski, G. J. ; Poughkeepsie, New York, U.S.A.) Sept. 26, 1934, Nos. 27610, 27611, 27612, and 27613. Convention dates, Sept. 27, 1933, Oct. 20, 1933, Dec. 1, 1933, and Dec. 29, 1933. [Class 23] A centrifugal bowl having outlets for sludge at its periphery has at each such outlet a hollow body with a conical valve head movable outwards to close the outlet and inwards to open it, means being provided for controlling the supply and discharge of liquid to and from the hollow body to cause it to move into and out of the closed position. Fig. 3 shows a cross-section through one of the outlets 8 which is adapted to be closed by a hollow body 13 slidable in a guide tube 17 fixed to the bowl. The inner end of the body 13 is situated at a radial distance from the axis between those of the outlets for the lighter and heavier liquid separates so that liquid penetrates through holes 21 in its inner end and normally fills it. A leak port 15 is provided at its outer end and a slight flow of liquid continues until the entrance to the tube 17 is closed by an accumulation of sludge whereupon the body 13 empties until it is sufficiently buoyant to move inwards to open the outlet 8. To avoid waste of the liquid to be treated, the body may be supplied with liquid separately introduced into the bowl within a conical partition 22 from which the liquid is fed to the valve body 13 through a pipe 23 and a passage through a guide 19. The valve in this case is caused to open by cutting off the supply of control liquid. To prevent the control liquid from mixing with the liquid to be treated, the body 13 may be open at its inner end and placed nearer to the axis, a lip being formed on its lower inner edge to spill any surplus liquid supplied. To shorten the time of emptying the valve body in the automatically acting device the greater part of the space within the body may be taken up by a cylindrical projection 33, Fig. 8, fixed relatively to the bowl. To prevent small quantities of waxy material from stopping up the port 15 the annular passage between the tube 17 and the valve may open into a chamber 34 in which the wax is centrifugally trapped. Fig. 5, shows a modification in which a much heavier valve body is partially counterbalanced by a spring 28 having adjustment nuts 29. In this case the valve may be caused to move inwards by slightly reducing the speed of the bowl. As an alternative to the spring 28 a compression spring may be arranged between the periphery of the bowl and a shoulder on the valve body 13.
