Title: Information storage and retrieval systems
IPC: G07C9/00
Filed: 1969-02-05
Abstract: 1,235,944. Reserving seats &c. INTERNATIONAL COMPUTAPRINT CORP. 5 Feb., 1969 [20 Feb., 1968], No. 6138/69. Heading G4T. A remote station adapted for communicating with a central controller in an information storage and retrieval system, e.g. a system for booking theatre seats, includes means for formulating, visually displaying and communicating a signal, for receiving and visually displaying a reply signal from the controller, for storing the two signals in a memory and for printing a ticket to represent the reply signal stored in the memory. In operation, the central controller 180 (Fig. 1C) transmits a carrier signal to the communications interface and message structuring logic unit 86 of each station. Absence of this signal when the station is switched on operates an alarm 142. If the signal is received, a carrier signal is transmitted to the computer, signifying that the station is operating. The computer then transmits an addressed message modulated on the carrier signal to ask each station in turn whether seats are required. This message is received by unit 86 via line 138 and, if the address is correct, unit 86 conditions data set 134 for responding to the message. In those stations ready to transact, send control 92 will have been operated so that an affirmative response is now transmitted. Such stations are then asked in turn to transmit their transaction message by a signal which conditions data set 134 accordingly, the message then passing from a memory 52 through unit 86 to the computer. Setting the transaction message.-Either key 62 or key 64 is depressed according to whether ordinary or season tickets are required. Mode control 72 then sends appropriate mode characters to memory 52. Date, time, place &c. information is then selected on keyboards 10, 12, 14 and fed to memory 52, sequencer 30 controlling register 44 to ensure that each piece of information is stored alongside the correct mode character. The transaction message is displayed on CRT 82. The computer, on receiving the transaction message, scans its memory 181. If the seats required have not been issued, their booking is now entered in the memory and a signal confirming booking is sent to the station. The confirmation message is fed to memory 52 and displayed on CRT 83. Unit 86 conditions a ticket printer interface 152 to accept the message from memory 52. Upon depressing an " accept " key 24, interface 152 accepts the message and feeds signals to control a ticket printer 156 accordingly. The transaction message sent by a station may not be complete; the exact designation of the seats required, for example, may not be known. In this case, part of the transaction message is left blank and the reply from the computer indicates what seats are available.

Title: A process for the production of cyclohexanol and cyclohexanone
Filed: 1960-02-22
Abstract: Cyclohexanol and cyclohexanone are produced by oxidizing cyclohexane in the liquid phase by means of a gas containing molecular oxygen, the reaction being carried out in the presence of an oxidation catalyst and a lower saturated aliphatic anhydride, such as acetic anhydride.  The proportion of acid anhydride employed is 1.0% to 50% based on the weight of cyclohexane.  The oxidation is preferably carried out at a temperature of 120 DEG C.-165 DEG C. under a pressure of 50-250 p.s.i.g. The preferred oxidation catalyst is cobalt naphthenate, but hydrocarbonsoluble compounds of copper, aluminium, chromium and manganese may also be used.  Cyclohexanone may be added as an oxidationinitiator.  The examples relate to the oxidation of petroleum cyclohexane that contained 87.6% cyclohexane by weight.

Title: Improvements in aircraft brake systems
IPC: B64C25/48
Filed: 1945-03-13
Abstract: 592,319. Aircraft landing - wheel brakes. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. W. March 13. 1945, No. 6225. [Class 4] In fluid pressure operated wheel brake apparatus for aircraft comprising a pair of valves respectively controlling brakes on opposite sides of the aircraft the valves are arranged to be differentially operated for steering by pivotal movement of a rudder bar and also by auxiliary means independent of the movement of the rudder bar. As shown, wheel brakes 3, 4 on opposite sides of the centre line A-A of an aircraft are applied by pressure fluid from a bottle 5 controlled by a pair of valves arranged in a housing 6 and which may be operated to apply equal pressures to the two brakes by a hand lever 7 and cable 25a and differentially to apply unequal pressures by rotation of a spindle 9. Pedals 10, 11 fixed to shafts 18, 19 mounted on the rudder bar 1 are connected by arms 16, 17 and links 12, 13 to a plate 14 pivotally mounted so as to rock about an axis B-B, on the spindle 9 which is thus turned about a vertical axis by swinging move - ment of the rudder bar about its pivot 2 and also without such' movement by differential movement of the pedals relatively to the rudder bar. If the pedals are equally moved the plate 14 swings idly about the pivot B-B. According to the Provisional Specification the mechanism comprises a vertical beam pivoted at its middle point on the crank of the apparatus described in Specification 507,162 by which differential application of the brakes is obtained. The ends of the beam are linked to crank arms on shafts which are mounted on the rudder bar and to each of which a pedal is secured, the arrangement being such that when one pedal is operated the beam pivots on the end of the link that is connected to the other pedal and thus operates the crank which carries the beam. The existing connections between the rudder bar and the valve mechanism may be retained. The apparatus described in Specification 430,842 may be used instead of that of Specification 507,162.
