Title: Self synchronising data decoder for modified frequency recording - uses voltage ramp generated by input transitions fed to bank of comparators to generate data output and data valid signals
Inventor: MARA JOZSEF
IPC: G11B20/14
Filed: 1981-05-12
Abstract: To increase the density of magnetic recording it is desirable to minimise the number of flux transitions used to identify each bit of data whilst maintaining self synchronisation. The decoder uses a defined time base and compares this with the input signal at defined instants using logic circuits and a frequency modification coding. The circuit has compensation inputs to accommodate for variations such as speed and temperature. The input signal transitions are converted into short duration pulses which synchronise a sawtooth generator. This waveform is supplied to one input of each of four comparators. The other comparator inputs are provided by a control circuit via a resistor divider chain. Compensation inputs to this circuit provide reference voltage changes for such things as temperature and speed variations. The comparator outputs provide a short pulse at the start of each transition window and a data valid pulse. The data output is provided by two bistables. The first one toggles every time an input pulse is not detected within a data bit period.

Title: Open segmental piston ring mfr. - entails creating local weak point in closed ring then stressing until fracture occurs at weak point
Inventor: ALLINQUANT JACQUES GABRIEL
IPC: B23P15/06
Filed: 1982-05-12
Abstract: The process is used to make an open segment from a closed ring and may be used to fabricate piston rings for shock absorbers or gas struts etc. Initially material is cut away e.g. to obtain a local reduction in thickness (2) forming the start of a break. The ring (1) is then stressed to induce a fracture at the weak point. Fracture may be induced by forcing the ring onto a conical former (3), by applying radial shear forces at the weak point, or by the application of radial shock.

IPC: B23H1/02
Filed: 1982-06-07
Abstract: In the case of the proposed electrical erosion processing of workpieces which carry current, with relative movement between the tool (1) and the workpiece (2), the amplitude of the ignition voltage pulses is suitably controlled, also as a function of the breakdown voltage, in order to achieve the profile that is to be obtained for the workpiece surface being processed. The feed movement of the tool (1) is produced by a control unit (17) via a feed unit (16), and it is supplied via a decoupling device (15) from a power pulse generator (13) and an ignition pulse generator (14). A control unit (19) acts on the latter, a unit (18) for calculating the amplitude of the ignition pulse voltage being connected to both control units (17 and 19).

Title: Plough sole breaker
IPC: A01B17/00
Filed: 1982-12-16
Abstract: The present invention relates to a device making it possible to break or fragment the plough sole which a share-type plough makes during the ploughing operation. Conventionally, the fragmentation of the plough sole takes place using an independent tool (chisel style) and generally by starting to plough. The present invention is a device which, fastened directly to the plough, makes it possible to break the said plough sole in a single operation and simultaneously with the action of the plough. It comprises a plate 1, intended to be fastened to the rear part of the ploughshare-carrier of the plough, and surmounted by an inwardly curved tooth 2 receiving, by bolt and fastening holes 3, a small ploughshare or wear plate 4.
