Abstract: 1,155,561. Discharge lamp arrangements. PATRICK & DREW Ltd. 22 June, 1966 [26 March, 1965], No. 12678/65. Heading H2H. An apparatus for starting and operating a gas discharge tube comprises an auto-transformer having two coils wound on the same limb of a laminated core, one coil 30 being connectible to a supply and both coils supplying the tube 8, and contacts interposed between the two coils disconnecting the coils from each other when a discharge has occured within the tube, whereafter the second coil 29 acts as a choke for limiting the discharge current. The autotransformer action only takes place during the starting of the tube. The contacts are part of an electromagnetic relay having a coil 7 connected across the coils 29, 30. The coils 29, 30 may be wound on the centre limb of an E- shaped core and a non-magnetic gap may be provided in the magnetic circuit.

Abstract: 652,600. Printing-machines. HOE & CO., Ltd., R. Aug. 8, 1947, No. 12832/50. Convention date, Dec. 23, 1938. Divided out of 640,173. [Class 100 (ii)] Damping apparatus for the forme cylinders of a lithographic printing-machine is constructed with a plurality of pumps 51 for supplying moisture to the damping rollers 84, 85, 86, 24 of each forme cylinder, and with means for individually regulating the moisture supplied by each pump and means for simultaneously regulating the moisture supplied by the plurality of pumps. Each pump has an inlet 64 connected to a supply tube 63, and each piston 53 is reciprocated by an oscillating lever 69 pivoted about a pivot 71 and oscillated by a cam-shaft 52. Each lever 69 engages a spring-pressed collar 66 on a piston 53 to move the piston upwards, and a spring 67 returns the lever until it is arrested by a screw 74. Each screw 74 is independently adjustable so that the amount of moisture applied to various lengths of the rollers 84 &c. is adjustable. The pivots 71 can be adjusted simultaneously by a screw 78 engaging a nut 81 on a lever 82 carried by the mounting of the pivot. The pump 51 ejects the moisture past a valve 57 on to a spreader plate 83 from which it passes to the roller 84. The shaft 52 is driven from a motor supplied by a generator driven by the associated printing-machine, and the drive can be a variable one as described in Specification 640,173.

Title: Duplex way station selector
IPC: H04L12/40
Filed: 1965-03-26
Abstract: 1,096,403. Telegraphy. STANDARD TELEPHONES & CABLES Ltd. March 26, 1965 [March 30, 1964], No. 12914/65. Heading H4P. A duplex telegraph system comprising a central station and a number of way stations is arranged substantially as shown. The operation of the way station receiver and transmitter is under the control of programmed counters. The various components are described in detail in the Specification: transistor circuitry is used. The several modes of operation are described below. Central Station has data for way station.-The central station CT sends a Mark signal which prepares the control circuits RCC in all the way stations to receive the message preamble and to block the teleprinters RTP. The receiving counter RC is at count 1. The call letter B of the required way station WS-B is then sent, RC steps to 2, and receiver RTP is unblocked. This is followed by Line Feed, at which the paper supply is checked and SAB returns to CT an answer back signal, and then by a repetition of call letter B, at which RC steps to 3 and RTP is again blocked. Other way stations are called in, if required, by the sequence call letter, LF, call letter. The preamble ends with a space signal which steps RC to 4 and unblocks RTP at the selected way stations so that they may print the message text which follows. The end of message signal resets RC to step 1 and blocks the receivers RTP. Way station has data for central station.-The central station CT polls the way stations in turn, each way station returning a yes/no signal indicating whether or not it has data to transmit. If no station has data during polling but later a way station does have data to transmit, the station calls the central station which then polls the way stations as before. When, in response to a poll, a yes signal is returned the sending counter SC of that way station steps to 2. The central station replies with a carriage return signal, SC steps to 3, and the message is transmitted. If the central station has a message to transmit while the way station is transmitting, the way station must stop transmission of the message when the call letter is received so that the answer back may be sent, whereafter the message is resumed. When the way station transmits the end of message signal, counter SC steps to 4. The central station acknowledges this signal with a line feed signal which returns SC to 1. Alarms operate in the event of incorrect operation of apparatus in the way station and in the event of incorrect sequences of signals.

Title: Improvements in or relating to catalysts
IPC: B01J37/00
Filed: 1957-04-24
Abstract: A reforming catalyst comprising essentially calcined alumina and a metal of the platinum family is characterized by: (i) a large pore base structure resulting from the drying and calcination of a mixture of precursor hydrous alumina phases containing 65 to 95% of trihydrate and 5 to 35% of boehmite or amorphous alumina; (ii) 0.18 to 1.5% of a platinum family metal present in a sufficiently finely divided form to exhibit the absence of crystallites and crystals of size larger than 50 <\>r as determined by X-ray diffraction: and (iii) the substantial absence of pores of less than 10 <\>r radius as the result of a sintering process applied before or after the incorporation of the platinum family metal.  Platinum, rhodium, palladium and iridium are the preferred platinum metals, ruthenium and osmium being less satisfactory.  The precursor alumina phase may be obtained as described in Specification 735,390 and the catalyst of the present invention may be obtained either by calcining the precursor to obtain the higher surface area catalyst described therein and sintering to obtain the low surface area catalyst in a subsequent stage or by effecting the initial calcination step under sintering conditions.  Calcination without substantial sintering may be effected in a flowing stream of gas inert to the catalyst base at 750 DEG  to 1200 DEG  F.  Sintering may be effected either in the presence of steam at 750 DEG  to 1600 DEG  F. or, less preferably, thermally in which case higher temperatures are used.
