Patent GB-547152-A (GB)
Title: Improvements in and relating to the manufacture of cellulosic film
Filed: 1940-11-25
Abstract: 547,152. Films. BRITISH CELLOPHANE Ltd. Nov. 25, 1940, No. 16916. Convention date, Dec. 1, 1939. [Class 2 (ii)] In order to prevent or retard the formation of a deposit on the lips of the film-forming slot from which a cellulosic solution is extruded into an aqueous coagulating bath containing acid, there is added to the bath a small amount of a phenyl sulphonic acid substituted in the nucleus with an aliphatic radical containing 10-14 carbon atoms. Films of uniform thickness and appearance, free from streaks and scratches, can thus be obtained over long periods of working. The preferred sulphonic acids are those in which the aliphatic radical is in the para position. A mixture of sulphonic acids may be used. Instead of adding the free acid to the bath, the substance may be added in the form of its sodium or other salt. The proportion of the added substance may be 0.002 - 0.02 per cent. of the weight of the coagulating liquid. The process may be used in the production of films from aqueous, preferably alkaline, cellulosic solutions such as viscose, cuprammoniumcellulose solutions, and solutions of alkalisoluble, lowly-esterified or lowly-etherified cellulose. In an example, viscose is extruded through a slot into a solution of sulphuric acid and sodium sulphate containing a little p-decyl phenyl sulphonic acid or ptetradecyl phenyl sulphonic acid. In another example, the added substance is a mixture of alkyl substituted phenyl sulphonic acids in which the alkyl groups are straight chains of 10-14 carbon atoms or a mixture of alkyl substituted phenyl monosulphonic acids in which the alkyl groups have single branch chains and contain an average of 10 carbon atoms. The use of triisobutyl - phenyl mono-sulphonic acid is also specified. Specifications 211,446, [Class 2 (ii)], and 453,778 are referred to.

Title: Controlled access systems
IPC: G06Q20/40
Filed: 1975-04-25
Abstract: 1458495 Controlled access systems INTERNATIONAL BUSINESS MACHINES CORP 25 April 1975 [25 June 1974] 17146/75 Heading G4H In a controlled access system, a request for access includes the entry of two messages at a request station, one of which is encoded at the request station and the other at a control station, testing means generating on access enabling signal if there is correspondence between the encoded forms of the two messages. In a banking system, digits (including an account number) are read from a credit card 100 at a terminal (Fig. 3) and some of them are selected by a key K1 and encrypted 106 under control of a key A (originally entered at the terminal, or derived by encrypting an entered key A<SP>1</SP> under control of a key C). Groups of the output bits from encryption 106 are used to access decimal digits in the range 1-9 from a table 110 and some of these, selected by a key K2, are compared 114 with corresponding digits of an I.D. number entered by the customer on a keyboard 112, to permit the customer's transaction to proceed, assuming equality. The I.D. number is augmented by appending further digits derived by bit-wise EXCL-ORing of existing digits, at 116, the result being encrypted 118 under control of key A, two of the resulting 8 digits being replaced at 120, 122 by variable data (a cash counter count for cash issue transactions, and a transaction number for other transactions), followed by encryption under control of key B at 124, to form an encrypted portion of a transaction request message to be sent to a host computer, the message also including a header (specifying type of transaction &c.) and (non- encrypted) information from the card 100 (ineluding the account number) and from the keyboard (types of account involved, amount). In the host computer (Fig. 4), the encrypted portion is decrypted 142 (to reverse the encryption 124), the encrypted I.D. number in the result being compared 150 with an encrypted I.D. number read from a stored customer file accessed under control of the non-encrypted information in the transaction request message. Whether the transaction is allowable from other points of view, is also checked. A transaction reply message is sent to the terminal, including a header, an encrypted portion (comprising two terminal cash counts, an action byte, and an amountof-bills-involved byte, encrypted under control of key B) and non-encrypted information. At the terminal (Fig. 5), the encrypted portion is decrypted 162 and the transaction is concluded 164. A status message is sent to the host computer, comprising a header, an encrypted portion (the transaction number, the two terminal cash counts, and a count of status and inquiry data bytes following the encrypted portion, all encrypted using key B) and the status and enquiry bytes referred to (non-encrypted).

Title: Improvements in compressed air brakes for railway and like vehicles
IPC: B60T8/18
Filed: 1924-07-18
Abstract: 219,331. Drolshammer, I. July 18, 1923, [Convention date]. Fluid-pressure.-Compressed-air brakes are provided with a plurality of brake cylinders on each vehicle, one or more of which may be brought into commission by means of a plug cock to vary the braking pressure in accordance with the load, the time required for filling any number of cylinders being kept substantially constant. The cylinders out of commission are connected to atmosphere, and only those auxiliary reservoirs which feed the cylinders in commission are recharged on releasing the brakes. Fig. 1 shows the general arrangement when two brake cylinders 95, 96 are employed, the passage of compressed air from the main pipe 41 to the auxiliary reservoirs 93, 94, and thence to the brake cylinders by the pipes 67, 68 being controlled by a distributor B, which may be of the kind described in Specification 214,092, and a plug cock 69 of the form shown in Figs. 2 - - 4. With the. plug in the position shown in Fig. 4, for a loaded vehicle, both auxiliary reservoirs are charged directly from the train pipe through the non-return valves 84, 83, Fig. 2, passages 45, 86, 87, plug channel 88, 89, and passages 43, 44, whilst communication between the auxiliary reservoirs and both brake cylinders may be had through passages 70, 74 in the plug, the passage 46, and the valve B, also through a smaller passage 75 and the valve B, the cylinder 95 being supplied directly from the valve B through the pipe 67, whilst a channel 76 in the plug serves to supply the cylinder 96 by connecting the pipes 67, 68 by passages 48, 49. When the plug is turned to the left for braking light vehicles, so that the end of the channel 89 registers with the passage 87, the supply to the reservoir 93 is cut off as the channel 88 no longer registers with the passage 86, and the cylinder 96 is cut out as the groove 76 no longer connects the passage 48 with the passage 47. The supply to the cylinder 95 is now effected partly by the passages 70, 74 and 46, and partly bv the throttled passage 71 and the passage 75, so that the time required for a full application remains the same, and the cylinder 96 is now connected to the exhaust passage 47 by the plug channel 85. If the plug is rotated still further to the left, to throw the passages 44, 70 out of register, both the auxiliary reservoirs are closed, the supply to both brake cylinders is cut off, and they are both connected to atmosphere by the plug channels 70, 77. If the plug on an isolated vehicle is placed in this position, the vehicle may be braked by means of the air retained in the auxiliary reservoirs by turning the plug to one or other of its application positions.
