Title: Data transmission system
IPC: H04L7/02
Filed: 1961-08-11
Abstract: 972,057. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1961 [Aug. 25, 1960], No. 29020/61. Heading H4P. In a self-clocking data transmission system locally generated strobe pulses nominally at the bit-frequency of the data being received are combined with the received data in such a way as to produce an indication as to whether they lead or lag the centre of each bit received and as a result an appropriate adjustment is made to the phase of the strobe pulses. As described, strobe pulses 4.1, Fig. 7, which should occur at the centre of each bit period are produced by dividing pulses from a local oscillator by 32 and to test whether the strobe pulses are occurring at the mid-points of each bit a count of the local oscillator pulses 33 is made between the leading edge of a " 1 " bit and the next strobe pulse and between the next trailing edge of a " 1 " bit and the next strobe pulse. If the strobe pulses are correctly centred the count reached should be 32, whereas if the strobe pulses lead or lag the centre positions the counts reached will be less than 32 or greater than 32 respectively. If for each of three consecutive counts either more than 32 or less than 32 is reached then the phase of the strobe pulses is altered by making the next strobe pulse occur either after 31 or after 33 local oscillator pulses. This is effected by a circuit shown in Fig. 4. Normally, when the strobe pulses are correctly centred, this circuit receives local oscillator pulses 3.3RR and divides by 32 to produce strobe pulses 4.1, division by 4 being effected by triggers 66, 67 and gates 71, 72, 73 and 74 and a further division by 8 being effected by triggers 68, 69, 70. If more than 32 pulses are counted on each of three consecutive counts an advance signal is produced (Figs. 5 and 6, not shown). This opens a gate 75 and results in triggers 66, 67 dividing by 3. Alternatively, if three consecutive counts of less than 32 are made, then a retard signal is produced which results in triggers 66, 67 dividing by 5. Specification 972,058 is referred to.

Title: Improvements in or relating to the production of cellulose ethers
IPC: C08B11/00
Filed: 1938-10-07
Abstract: 519,907. -Cellulose ethers. DU PONT DE NEMOURS & CO., E. I., MAXWELL, R. W. Oct. 7, 1938, No. 29161. [Class 2 (ii)] Cellulose is converted into cellulose ethers of low degree of etherification insoluble in organic solvents and in water, by uniformly wetting the cellulose with a caustic alkaline solution of less than mercerising strength containing a substantially non-volatile etherifying agent dissolved in it, and evaporating the solvent from the reaction mass until it feels dry to the touch, and then maintaining the mass at a suitable temperature until the etherification is completed. After removing the solvent the reaction mixture may be further heated. Sodium methyl sulphate, sodium ethyl sulphate, sodium chloroacetate, glycerol mono-chlorohydrin, or benzyl chloride may be used as etherifying agent. Steeping may be effected in the cold or at raised temperature. The amount of steeping liquor left after the excess has been removed may amount to as much as that which will not drain freely from the cellulose by gravity without external pressure. The steeped cellulose may be pressed to contain only a small steeping liquor, prior to the evaporation step. The solvent may be evaporated by passing the impregnated cellulose over hot drying rolls or through a drying column. The material treated may be in the form of a continuous web or sheet. Long fibre cotton, yarn, or woven goods may' be treated so as to modify their dyeing, lustre, wetting, or other properties. The products may be used for making other cellulose derivatives, or if they are capable of being dissolved in aqueous alkaline solutions, they may be used in the production of filaments, films, sizes, coatings, or fixing agents for pigments. The impregnating solution may be aqueous or alcoholic. The,amount,of caustic alkali in the etherification mixture may be equivalent to that of the etherifying agent or less. Wetting agents such as the sodium salts of acids derived from alcohols made by reduction of carbon monoxide catalytically under pressure may be used in the steeping solution. Products may be obtained which are soluble in dilute caustic soda solution after cooling to below 0‹ C. In an example, sulphite pulp is subjected to mercerisation and steeped in a solution of caustic soda and sodium methyl sulphate. After steeping, the sheets are pressed and then heated in a current of air until dry. They are placed in a container and after displacing the air by nitrogen, they are allowed to age for a few days at 60‹ C. The sheets are then washed with cold water and then formed into a slurry with caustic soda solution. On cooling to below 0‹ C., a viscous solution is obtained. The cellulose ethers obtained by the process may be subjected to xanthation, and the cellulose ether xanthates may be converted into filaments.

Class 143 An automatic feed weigher of the kind in which a predetermined weight of the stream of fed material, corresponding to the weight of suspended material at cut off, is diverted into a compartment 11 of the weigh pan 2 during one weighing operation, and is transferred into the main portion of the pan, after it has been emptied, to form part of the next charge, is characterized in that means are provided to regulate the quantity of material diverted to compartment 11. As shown in Fig. 2 material is fed to pan 2 from main and dribble feed hoppers provided with gates 16, 21 respectively; on the closing of gate 16 a motor rotates, through one revolution, a pair of concentric cams 18 which close contacts 19, 20 and so energizes a solenoid 10 for a period of time determined by the relative angular adjustment of the cams. When the solenoid 10 is energized a deflecting plate 7 is moved to the position shown in dotted line. On completion of the weighing operation the pan tips about axis 2a to discharge its contents, and, in its return movement causes an abutment 15 to open the discharge door 12 of compartment 11. In the modification shown in Fig. 4 closing of gate 16 disengages a ratchet lever 23 from pendulums 22, 24 so permitting plate 7 to be moved to its diverted position by pendulum 22 for the period that pendulum 24 takes to swing down and release a lever 27 from engagement with a further pendulum 26 which latter pendulum then returns the plate 7 to its vertical position. In this embodiment the deflection time is adjusted by movement of the weight of pendulum 24 along its rod. In a further modification (not shown) the quantity of material diverted is regulated by adjusting the cross-section of the feed orifice and maintaining the period of deflection of piate 7 constant.

Abstract: 838,137. Respiratory appliances. NORMALAIR Ltd. Dec. 23, 1958 [Sept. 25, 1957], No. 30027/57. Class 81 (2). A respiratory appliance has a mask 10 connected by a tube 6 to a breathing bag 5. This is supplied with breathable gas from a cylinder 1 through a valve 3, controlled by the expansion and contraction of the bag. An exhalation valve 16 is connected to the tube 6 between the mask and the bag and is loaded by a light spring. With this arrangement the initial part of the exhalation, which is relatively free from CO 2 , passes into the bag and inflates it before the pressure is sufficient to open the exhalation valve. When this pressure is reached, however, the latter part of the exhalation, which has a high CO 2  content, passes out through the valve. On inhalation, the contents of the bag are first rebreathed, followed by such additional gas as is admitted from the cylinder 1. The valve 3 is preferably of the type in which a head is tilted off its seating by the engagement of a long, inclined stem, attached to it, with the opposite face of the bag, when this is drawn inward. Specification 775,314 is referred to.
