Title: Variable inertia flywheel assembly esp. for motor vehicles - is in two parts mechanically or electromagnetically coupled
IPC: B60K17/04
Filed: 1979-04-23
Abstract: Variable inertia flywheel assembly is esp. for motor vehicles. The assembly provides differing inertia as required by the engine where the vehicle may be negotiating complex routes and increases fuel economy. The assembly is based on the use of two separate flywheels one having considerably less inertia than the other two flywheels being mechanically coupled and decoupled as the engine demands. The two flywheels are concentric about each other and may alternatively have electromagnetic coupling between them. The assembly can also act as an electrical generator. The main flywheel (5) is attached to the motor shaft in the normal way (1). The second flywheel (6) acts as a rim and one side wall to the first and can run on a ball race (9) over it. Coupling is by friction pads (12) carried by sprung (13) weights (11) at the rim surface.

Title: Numeric control for three=phase oscillator - is by comparison of numeric sinusoids and of sawtooth waveform
Inventor: FERT RENE
IPC: H02M7/529
Filed: 1979-07-06
Abstract: Numeric control of three phase oscillators esp. high powered thyristor circuits used in electric motor control. Control is based on the generation of three 120 deg. displaced sinusoids and a sawtooth waveform at three times the sinusoid frequency, both waveform types being represented numerically. A clock source working at a frequency (NsFs) which is a product of the number of waveform steps and their frequency, feeds a periodic counter (5) working between zero and number of steps - 1. This controls three passive programmed memories (6,7,8) providing a binary output representative of the sinusoid step amplitudes. The binary signals are multiplied (9,10,11) and compared (12,13,14) using a further clock source working at the product of the number of sawtooth steps and three times the sinusoid frequency. A second counter (NdFd) works between zero and three times the sinusoid frequency and supplies a further counter (15) and memory (16) the binary words feeding the comparator second inputs.

Title: Three=dimensional locating system for mobile tool member - assigns position vector for all theoretical locations which is corrected as function of field position
Inventor: CLEMENT ANDRE
IPC: B23Q17/22
Filed: 1979-12-12
Abstract: The orthogonal axis placement of a sensor or tool is accurately performed without feedback circuits by experimentally measuring the location performance of the mechanism against a theoretical reference location field. Correcting the signals, based on these measurements, are used to position the mechanism on each of its three axes. The movement is controlled by a set of adjustable cams or by electronic control using electronic memories. The errors in the angular position of a vector (V) related to a movable part of a tool which undergoes a translation, and a rotation is determined by evacuating the scalar product of the displacement vector with a tensor. The field of the position vectors is determined by placing either a sphere or a cylinder on a plane surface and contouring them with the extendable part of the tool.

Title: Planographic printing plate - with untreated organo-polysiloxane non-image areas and ink receptive low temp. plasma treated image areas
Inventor: TAKEUCHI SATOSHI
IPC: G03F7/40
Filed: 1980-04-29
Abstract: Planographic printing plate comprises a carrier plate and a layer of an organopolysiloxane. The non-image areas comprised of untreated polysiloxane, and the image areas are formed by selective chemical treatment of these areas with chemical species activated in a plasma state. The plates are made by applying a layer of a photoresist material to a base plate comprising a carrier coated with a layer of an organopolysiloxane. The photoresist layer is imagewise exposed and developed in the usual way and the resulting uncovered organopolysiloxane areas are exposed to a low temp. plasma to render them ink-receptive. The remaining plasma-resistant photoresist layer is then removed with a suitable solvent. A layer of abrasion-resistant ink-receptive material may be provided on the image areas. The plasma treatment extends throughout the thickness of the organopolysiloxane layer, thus giving printing plates with excellent wear resistance capable of making large numbers of copies. The plasma treatment is carried out in a short time using little energy, and gives high resolution images.

Title: Dynamic MOS memory store access controller - allows asynchronous processor and memory read and write cycles so that no processing time is lost by satisfying memory control constraints
Inventor: GIRARD PAUL MARIE
IPC: G06F13/42
Filed: 1980-05-30
Abstract: The system allows a processor to operate asynchronously w.r.t. its memory making use of cycle request, read request and write request control signals to access the memory with a cycle time independent of the memory refresh cycle times. When the write request and cycle request are raised at the same time the write cycle is started as soon as the request has been latched by the memory. If the cycle request is raised alone, a read cycle is initiated and a write permit signal sent to the processor. The cycle is completed by a read request from the processor, whether or not the data is used. If, whilst the write permit signal is present, the processor produces a write request then a normal memory write cycle is executed. If after the write permit signal has been removed but within the cycle a write request is generated a second type of write cycle is executed within the processor cycle.
