Filed: 1973-12-10
Abstract: 1409389 Digital data storage INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1973 [23 Jan 1973] 57142/73 Heading G4C [Also in Division H3] Synchronous binary data signals in which successive data elements are represented by signals of opposite polarity are detected by intergrating the difference between the signal level and the mean of the values at the beginning and end of the bit period. It is explained that signals closely packed on a magnetic disc are affected in level by the signals in adjacent bit periods and by varying background level. Accordingly the signal and the previous signal delayed at 3 by a bit period are summed at 4 and half of this value i.e. the mean value is extracted. This is sampled at the end of each bit period and the difference between this value and the delayed signal is integrated at 6 an output signal being provided if the output of the integrator exceeds a given value.

Title: Dispensing mechanism for cylindrical objects
IPC: B65G47/51
Filed: 1978-09-06
Abstract: A dispensing mechanism has a horizontal, rotatable disc 5 on to which cylindrical objects are placed at random and which by rotating causes the objects to be guided by radial guide means 9 in a line into a passage 13 at the end of which the objects pass singly or in groups through the outlet of the mechanism. The guide means comprises a guide member 9 which can rotate about a shaft 8 coaxial with the disc and is held resiliently against rotation by co-operating with a projection 10 on a wall of the passage 13. When a sufficient pressure is exerted on the guide member due to crowding or jamming of the objects in front of the passage entrance 12, the guide member 9 is forced past the projection 10 thereby relieving the pressure. The guide member 9 having been carried round by the objects on the disc 5 becomes operative again when it again contacts the projection 10. <IMAGE>

Abstract: A baling machine for making large rectangular bales of straw or hay has a bale chamber with an entry opening 21 at one end. Material is fed under 43 compression to the entry opening by packing fingers 22 to fill the chamber. So that the bale is formed of consolidated columns of material a guide 31 is located adjacent the entry opening and can be moved in and out of the chamber after each column is formed.
