Title: Production of hcn
IPC: B01J19/24
Filed: 1962-04-02
Abstract: <PICT:0968519/C1/1> HCN is made by reaction of NH3 with a volatile hydrocarbon at elevated temperatures in a tubular reactor whose length is 80 to 200 times its internal diameter, in the absence of catalyst. The hydrocarbon is aliphatic, aromatic or alicyclic, or a mixture thereof, and has a boiling-point below 600 DEG  F. (316 DEG C.) at atmospheric pressure.  Preferably the hydrocarbon is aliphatic, having 1 to 8 C atoms per molecule, e.g. CH4.  The stoichiometric amounts of hydrocarbon and ammonia are preferably used, or ammonia may be in slight excess; the product obtained is then carbon-free.  An inert diluent, e.g. H2 or N2, may be used with the feed gases, preferably one mole diluent per mole reactant gas. In Fig. 1, the reactants enter at 21 and pass through water-cooled holder 14 which makes gas-tight good electrical contact with reactor 10 which may be a single length of graphite tube or short sections of graphite tube joined by threaded graphite couplings 20.  The residence time in the reactor may be from 0.2 to 0.01 secs., and the gases should be at or near atmospheric pressure.  On leaving the reactor the gases should not come into contact with a hot surface; they leave tube 10 via water-cooled holder 15 and they may be cooled by indirect heat exchange in a water-jacketed outlet, or by water-quenching with consequent formation of aqueous HCN solution. Reactor 10 is within aluminium jacket 11 lined with firebrick insulator 12 and packed with carbon black 13 and is heated by electric current which flows from 25 through tube 10 and returns via jacket 11 to 39.  The reaction is preferably carried out at from 1600 DEG  to 2600 DEG  C.

Title: Improvements in or relating to sheet collecting and delivery mechanism for printing machines
IPC: B65H29/44
Filed: 1927-05-11
Abstract: 291,215. Timson, A. R. May 11, 1927. Delivery apparatus; cutting-apparatus.-Sheets severed from a printed web by tear-off rollers 45<a>, Fig. 1, are collected in a pile 9 on guides which are operated by ratchet mechanism controlled by an interchangeable bluff plate so as to drop and allow the pile to fall on to a conveyer 51 or other receiver when a predetermined number has been collected. The guides are in the form of arms 1, 2, spaced at 90‹ apart on shafts 3, 4 respectively coupled together for simultaneous movement in opposite directions by gearwheels 5 - - 8. A spring-actuated lever 11 engaging a squared block 10 on the shaft 3 prevents movement of the supports during the collecting of the sheets. Gearwheels 39, 38 couple the shaft 3 to a shaft 19 which is oscillated from a driving shaft 14 so as to turn the supports 1, 2 through 90‹ when the required number of sheets have been collected by means of a spring-pressed pawl 25 engaging ratchet-discs on the shaft 19 and pivoted on a bracket 17 freely mounted on the shaft and connected by a rod 16 to an eccentric 13 on the shaft 14. Three ratchet discs 27, 33, 36 of decreasing diameter are mounted on the shaft 19. the first two being freely mounted and the third being keyed thereto. The pawl 25 is wide enough to cover the three discs, but because of the difference in diameter, normally engages the disc 27 only. Deep notches 32 in the disc 27 allow the pawl 25 to engage the disc 33 at intervals and similar deep notches 34 in the disc 33 allow the pawl to engage the disc 36 when the notches 31, 34 are in register, so as to operate the supports 1, 2. Retaining pawls 40, 41 are provided for the discs 27, 33. To vary the number of sheets collected in each pile, a bluff plate 30, having one or more deep notches 31 is provided, so as to prevent the pawl 25 entering one or more of the notches 32 in the disc 27. Bands 45 carry the sheets into position over the supports 1, 2 when a pressure member 47, carried by an oscillating shaft 48, pushes them on to the pile 9.

Title: Improvements in the combination with a compressor of a motor for driving said compressor and a control device for the delivery of said compressor
IPC: F16K31/42
Filed: 1959-04-14
Abstract: 868,164. Fluid-pressure servomotor control systems; valves. ATLAS COPCO A.B. April 14. 1959 [Jan. 27, 1959], No. 12679/59. Class 135. [Also in Group XXVII] A mobile frame 1, Fig. 2, such as a motor vehicle, supports two compressors 4, e.g. of the screw, reciprocating, sliding vane or centrifugal type, each driven by an I.C. engine 2 through a step-up gear transmission 3 and e.g. a centrifugal coupling; the engines 2 are provided with centrifugal governors 68. Each compressor 4, which has an air inlet filter and silencer 8, delivers to a conduit 12, Fig. 3, via a pipe 9, a check valve 10 and a pressure equalizer 11. the latter having plates 35 of different length which form chambers 36 that effect silencing as well as pressure equalization. Each pipe 9 has one branch leading to an adjustable safety valve 13 and another branch connected via solenoidactuated unloading valve 19 to a pipe 22 having a silencer 23, Fig. 2, therein common to both compressors. The conduit 12 is connected through a hose 39 and a snap-coupling to the air intake of an aircraft 42; the conduit 12 is also connected to a double-beat blow-off valve 43, Fig. 4, common to both compressors and which leads to the silencer 23. The valve 43 is actuated by a diaphragm 48 the lower side of which is open to atmosphere and upper side of which is open to the pipe 12 through a restriction 65, the pipe 12 also being connected to a bellows 55 that control a spring-loaded hinged closure 57 co-operating with a nozzle 62 having a flow passage of larger area than the restriction 55 and connected to the chamber above the diaphragm 48, which chamber may be supplied with fluid from a source other than pipe 12. Upon closing a switch 24, Fig. 3, an electric motor 26 starts the engines 2 and the air delivered by the compressors 4 escapes through valve 19 and silencer 23 to atmosphere; after a given period a time-delay switch is opened and the solenoid of valve 19 is de-energized whereby the latter closes and the compressors build up pressure in the pipe 12; this pressure acts both on the diaphragm 48 to open the valve 43, and in the bellows 55 to cause the closure 57 to firstly throttle and then close off the nozzle 62 so that the valve 43 opens fully and the output of the compressor is directed to atmosphere. When air is being delivered to the aircraft the valve 43 is kept partly open and the pressure in the pipe 12 is kept at a constant value depending upon the spring-loading of the closure 57. The valve 19 may be dispensed with and the apparatus may be used for air conditioning or heating of aircraft cabins. The unit may comprise one engine and compressor only.

Title: Improvements relating to machines for the production of transmission chains
IPC: B21L9/00
Filed: 1927-05-13
Abstract: 295,439. Renold, Ltd., H., and Renshaw, A. May 13, 1927 Guards and protectors.-The driving clutch of a machine for assembling roller driving-chains requires the use of both hands of the operator to effect engagement. The spur gear 20, Fig. 26, that drives the main cam shaft 15 is loose thereon and acts through a clutch to provide a stop motion. A spring bolt 135 in the gear engages in a notch 138 in a flanged sleeve keyed to the shaft and can be locked in the disengaged position by a spring dog 191 with a nose engaging a recess in the bolt. Disengagement is effected by a treadle 165, Fig. 23, linked to withdraw a latch 142 that holds down a spring-pressed drawbar 139. On release the drawbar rises and a cam face 196 is projected into the path of a lug on the bolt 135. Both hands of the operator are required to effect re-engagement of the clutch. A hand wheel 152, Fig. 24, is chain geared to the cam shaft for rotating during setting-up, and is interconnected with the safety starting mechanism so that the clutch cannot be engaged when the hand wheel is clutched to the shaft and conversely. When the hand wheel; is pulled outwards to disengage its clutch 154, a spring bolt 159 enters a groove 161 and removes the other end of the bolt from the path of an arm 163 of a bell crank. The other arm 164, Fig. 25, can now be rocked by one hand free from a groove 165 to allow the other hand to pull out a knob 143 linked to the drawbar 139, which is thus pulled down removing the cam 196 from the path of the bolt 135 and engaging a lug 193 to retract the spring dog 191, thus freeing the bolt. The arm 163 now obstructs the rod 159 and prevents reengagement of the hand-wheel clutch. The spring 144 resets its associated parts when the main clutch is again tripped.
