Patent GB-629739-A (GB)
IPC: C06F1/20
Abstract: 629,739. Stapling-machines. LANGHAM, C. A. Nov. 13, 1947, No. 30232. [Class 89 (iii)] In a match-book making machine including a device A for stapling book assemblies, a pusher device D is provided which positions the assemblies in work holders on a conveyer B prior to stapling, but moves beyond its normal operative position if an empty work holder is presented to it to interrupt the feed of staple wire to the stapling device. The pusher device D comprises a cam-operated lever 23 to which is pivoted a plate 21 which engages a match book assembly M and positions' it in a clip 9 of a work holder 7 on the conveyor B. In the absence of an assembly M, the plate 21 engages a trip lever 30 to stop the staple wire feed. The assemblies M are inserted manually into the holders 7 by the aid of guides 17 in a yieldable table 15. The stapled match books are discharged by an ejector mechanism E comprising a pusher finger 40 carried by a rod. 38 which is movable towards its discharge position by a spring 41 acting through a cam retracted lever 33. A saddle member 39 carried by a sleeve 35 slidable on the rod 38 moves with the rod under the action of a spring 42 until it engages a holder 7. If it is not aligned with a holder, the saddle rides up and lifts the finger 40 clear of the holder to avoid damage. To stop the stapling device if an abnormally thick book assembly is presented to it, a belt drive therefor includes on the driving side a jockey pulley which is carried by a pivoted arm and distends the belt. Extra resistance due to a thick book tightens the belt, rocks the pulley and throws out a clutch.

Patent GB-2010489-A (GB)
Title: Monitoring Repetitive Signals
IPC: G01D3/08
Filed: 1978-12-06
Abstract: In monitoring repetitive signals from a source, signals are derived independently from the source in two synchronous channels (i.e. E.G.G. signals from different parts of the body). A coincidence detector 13 is used to identify the signals and to reject noise. The interval between coincidences is recorded by a counter 15 of clock pulses 16 which is set and reset by a monostable circuit 14. At each coincidence the total in the counter 15 is transferred by a latch 19 to an indicator. The transfer step is also controlled by a monostable circuit 18 having a duration longer than the expected interval. If a true source signal is absent in one channel, the expected coincidence does not occur and the interval count is extended. To suppress the indication of a false count when the following coincidence signal is received the indicator transfer step is inhibited if a single channel signal is received near the time when a coincidence is expected. A single signal is regarded as genuine if it occurs at the same time as a signal provided by a comparator circuit 25 connected to two D/A converters 26, 20 receiving the present interval count valve and the previous interval count value. Thus when there is a positive output from the comparator 25 and a NOR gate 23, connected as shown, the latch 19 is prevented from being activated by resetting the monostable circuit 18. <IMAGE>

Title: Internally coating metal pipes with thermoplastic materials
IPC: B05C19/00
Filed: 1980-04-29
Abstract: A thermoplastic internal coating is formed on a pre-heated metal pipe (1) by drawing an air stream through the pipe from the atmosphere using a pump (10) and periodically supplying a charge of thermoplastic particles entrained in gas through conduit (17) from a fluidised bed (20) of the particles and maintaining the velocity of the air stream through the pipe close to but not above the air transport velocity of the particles.
