Patent GB-459867-A (GB)
Abstract: 459,867. Accounting - machines. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. July 16, 1935, No. 20268. Convention date, Aug. 2,1934. Addition to 443,786. [Class 106 (i)] The machine according to the parent Specification is provided with mechanism operable for example by a special key to condition the machine for the entry of single amounts instead of the registration of series of associated transactions. The machine described in the parent Specification has a motor bar 12, Fig. 4, for initiating operations involving the entry of items of a series and an auxiliary motor bar 16 for initiating zero - amount and total taking opera. tions. Motor bar 12 is locked when the control lever is out of " Add " position, and motor bai 16 is locked upon the depression of an amount key or keys. According to the invention, the depression of a single-item key 250, Fig. 2, locks the motor bar 12 and disables the lock between the amount keys and motor bar 16 to enable the latter to be depressed to initiate an operation involving the entry of a single amount. The single-item key is maintained in depressed condition by a detent 280 until released by depression of a release key 251. Interlock between amount keys and auxiliary motor bar. Depression of the auxiliary motor bar, by a pin 34 projecting therefrom, rocks a slide 255, Fig. 7, upwardly. A pin 257 projecting from the slide is maintained by. a spring 261, Fig. 5, in abutment with the lower end of a pawl 260 pivoted to a second slide 252, whereby said second slide is also moved upwardly. In the event of the depression of an amount key prior to the motor bar, an arm 262 is rocked in known manner, into the path of a projection 254<a> on a pitman 254 connected to the slide 252, whereby both slides are locked and depression of the auxiliary motor bar is prevented. Disablement of interlock by single-item key. Upon the depression of the single-item key 250, Fig. 2, the pawl 260, Fig. 5, is swung out of the path of the pin 257 to permit the auxiliary motor bar to be depressed after the setting up of an amount and thus initiate a single amount-entering operation. Depression of the single-item key rocks a lever 271, Fig. 2, and sleeve 270, Figs. 2 and 6, clockwise to raise a slide 267. A stud 266 projects from the slide 267 into a cam slot 265, Fig. 5, in the pawl 260 and, as it rises, rocks the pawl to disable the coupling between slides 252, 255. The slide 255 is thus enabled to rise independently of slide 252, the locking of which no longer serves to prevent depression of the auxiliary motor bar. Interlocks with main motor bar. The main motor bar 12, Fig. 4, is locked upon adjustment of the control lever to a totaltaking position by a locking plate 264, that is moved bv a cam 290 on the control lever to position an abutment 263 in the path of a stud 73 on the bar. Similarly upon depression of the single-item key or the auxiliary motor bar, a locking arm 275, Fig. 6, is positioned beneath the stud 73 by means of the stud 266 or a stud 255<a>.

Title: Molybdenum catalyst and manufacture thereof
IPC: B01J23/28
Filed: 1966-10-17
Abstract: Epoxides are made by reacting in liquid phase olefins with organic hydroperoxides in the presence of a molybdenum containing catalyst prepared by reacting Mo metal with a peroxy compound which is an organic hydroperoxide, an organic peracid or H2O2 in the presence of at least one saturated alcohol having C1- 4, at a temperature of 25-100 DEG  C. Specified hydroperoxides are tertiary butyl, tertiary amyl, cumene, tetralin, \sHa -hydroperoxy di-isopropylketone, the hydroperoxide of 2-methylbutene-2, octene-1 and 2:6-di-tertiary butyl-p-cresel.  Catalyst effectiveness is determined by reacting tertiary butyl hydroperoxide and octene-1 to yield the corresponding epoxide. Reference is also made to the epoxidation of propylene to propylene oxide and the catalyst is described as generically useful in epoxidizing compounds of formula <FORM:1119476/C2/1> in which R1- 4 may be hydrogen, alkyl, aryl, alkaryl, aralkyl, alkenyl, alkadenyl or other functional groups.ALSO:An epoxidation catalyst is made by reacting molybdenum metal with an organic hydroperoxide, an organic peracid as H2O2 in the presence of at least one mono- or poly-hydroxy C1 - C4 alcohol at 25 - 100 DEG C.  In examples Mo is reacted with tertiary butyl hydroperoxide or peracetic acid using CH3OH3, C2H5OH or (CH3)3 COH as solvent.  Usually less than 1 gm. of Mo is dissolved and these catalysts containing most Mo are not the most effective in epoxidation of olefins.

Filed: 1966-10-24
Abstract: 1,128,998. Dovetailing. I. DIMTER. 24 Oct., 1966 [22 Oct., 1965; 23 Oct., 1965; 13 Oct., 1966], No. 47527/66. Heading B5L. A continuous dovetailing machine comprises a slotting cutter and a profile cutter to which the workpieces are fed by holders on conveyer bands or chain, the distance between the holders being different from that between the cutters so that at no given instant are both tools engaged with workpieces. As described, the machine cuts dovetails at both ends of workpieces of varying length. The machine has a frame having pulleys 2, 3 for moving a conveyer chains 5, 5<SP>1</SP>. The chains have holders 25, 25<SP>1</SP>, Fig. 21 for carrying the workpieces 26, 26<SP>1</SP> past a spindle bend having a slotting cutter 23, and profile cutter 24 driven by a belt 22 from a motor 20 movable about a pivot 19 by an hydraulic or pneumatic motor 21. The distance b between the holders is greater than the distance a between the centres of the tools. The workpieces are intially positioned by a stop 51 and after one end has been machined by the cutters 23, 24 in the spindle hand 11, the holders release the workpieces and the arms of a turnstile 13 engage thee ends of the workpieces to move them transversely of the direction of movement of the conveyer chains to a positioning device 14. The latter has bars carried by an endless band and aligns the uncut ends of the workpieces with a pivotally adjustable stop bar which further positions the ends of the workpieces whereupon the holders reclamp the workpieces while they are carried past a spindle head 12 for machining the last mentioned ends. Thereafter, the holders release the workpieces and a positioning device 16, Fig. 4, is lowered so that a pair of rollers 38, 39 driven by a motor 37 engage the workpiece and move it to a stop, the holders then gripping the workpiece again while it passes a glue applying device 15 consisting of a profiled roller 33 connected to a glue pump 32, the device being urged by a spring against the end of the workpiece. Each holder has a jaw fixed relative to the chains and a second jaw mounted on a pivoted lever having a follower for engaging a cam track for controlling the opening and closing of the holder. Adjacent the pulley 2, a track starting tangential to the holders engages workpieces in the now open holders and discharges them to conveyers 8, 9 which feed the machined and glued workpieces to a gluing press. One of the jaws of each holder is carried by the chains 5 and the other jaw by the chain 5<SP>1</SP> which can be adjusted relative to the chain 5 to accommodate workpieces of varying thickness.

Abstract: 1,031,520. Artificial respiration apparatus. BLEASE ANAESTHETIC EQUIPMENT Ltd. Dec. 12, 1963 [Dec. 17, 1962], No. 47546/62. Heading A5T. Artificial respiration apparatus for supplying gas to a user at a preset tidal volume and predetermined cycling rate during normal operation, has a value which opens on spontaneous inhalation by the user to cause cessation of the cyclic operation of the apparatus and permit passage of gas to the user. A bellows 12 is supplied with respirable gas at a constant rate through a pressure regulator 28 and a needle valve 30. When the bellows is inflated to a predetermined maximum, a valve 32 is opened by an over-centre mechanism 34 actuated through a link 46 by a biased lever 20 connected to the top plate 16 of the bellows, gas then flowing to a mask 54 via a second needle valve 48 to produce an inhalation. The bellows then deflates to a predetermined minimum when the valve 32 is closed by the over-centre mechanism and exhalation is permitted. The exhalation valve 60 is diaphragm-operated and is opened when the pressure in a control chamber 64 is reduced on closure of the valve 32. In the event that the user inhales spontaneously, a negative pressure created in the user's supply conduit 51 causes a diaphragm 74 to move to open a demand valve 72. If the bellows deflates below a predetermined minimum, the top plate 16 contacts a valve member 82 which opens a valve 80 through which respirable gas is supplied directly to the bellows via the pressure regulator 28, thus by-passing the needle valve 30. A blowoff valve 70 permits escape of gas to the atmosphere through a whistle 73 if the pressure in the mask rises above a predetermined maximum e.g. due to an obstruction in the user's lungs.

Abstract: 1,070,910. Data processors. WESTERN ELECTRIC CO. Inc. Dec. 5, 1963 [Dec. 13, 1962], No. 48044/63. Heading G4A. In a data processor in which instructions are decoded in overlap relation, a transfer instruction is positioned one or more instructions before the final instruction of an instruction sequence to be transferred from and is executed prior to said final instruction. In this way accessing of the undesired final instruction is avoided on transfer, despite the overlapping. As described, a given instruction is dealt with in three machine cycles as follows: Cycle 1-a programme address register addresses the programme store (portion). Cycle 2-the addressed instruction is passed to a preliminary instruction register, the command portion of the instruction being then decoded in a preliminary decoder and the address portion passed to an address register. If the instruction is a transfer instruction, the address portion is then passed to the programme address register, otherwise the latter is incremented by one and the address portion used instead to address a data store (portion). Cycle 3-the command portion is passed to a final instruction register from which it is decoded in a final decoder which gates data between the data store (portion) and a selected one of three data registers, via a buffer register. Successive instructions are overlapped in that cycle 1 for a given instruction is the same cycle as cycle 2 for the instruction before and cycle 3 for the instruction before that. Data address indexing is mentioned.
