Title: Hybrid electrical vehicle propulsion system - has constant output generator and I.C. engine
IPC: B60L11/00
Filed: 1974-01-22
Abstract: The hybrid system has an electric motor as a propulsion unit driven solely by a storage battery for a period when its tension is above a first preset value and by a constant output generator turned by an internal combustion engine when the battery tension falls below a pre-set value. The generator performance is sufficient to both propel the vehicle and recharge the battery. The difference between the fixed output performance of the generator and the variable input performance of the traction motor is used to recharge the batteries. The fact that the engine is used only at constant speed and performance permits a favourable layout to minimise toxic exhaust emission.

Title: Preventing sediment residue formation in thermal appts - uses fluidising solid particles in fluid flow of reduced velocity
Inventor: MIKHAILOV G M
IPC: F28F19/00
Filed: 1975-02-14
Abstract: The formation of sediments on walls of apparatus used as reactors or heat exchangers, in the chemical and petrochemical industry is prevented by bringing the solid particles, which are fed into a liquid stream to be processed, into a pseudo-fluidised condition, using the stream of the processing medium. The fluidised particle stream is imparted a velocity lower than that required for their washing away. The prticles must be inert with respect to the processed medium. The apparatus housing may contain parallel tubes ending in tube plates with inlet and outlet branches for the processed medium. A gid supports the solid particles above the inlet branch, and uniformly distributes the processed medium flow.

Title: Back washing filter for fluid purification - with variable filter areas particularly useful for taking samples in automatic analysers
IPC: B01D46/00
Filed: 1975-09-04
Abstract: A back-washing filter for removing solid particles from fluids incorporates a helicoidal element, e.g. a spring. The interstices between the spirals act as a fluid screen. The sizes of the interstices can be varies by compressing or expanding the spring, which is fitted between an entry tube and an outlet tube. The feed flows continuously through the inlet tube, the spring and the outlet tube, which are contained in a concentric shell with a filtrate outlet and a wash water inlet. One end of the shell is fixed rigidly to the inlet or the outlet tube, while the other end is connected by a fluid-tight joint to the other tube. Means, e.g. a piston operated by compressed air, are provided for altering the distance between the inlet and outlet tubes and thus the distance between the spirals of the spring. The filter may be adapted for filtering solid particles from a gas by fixing one end of the spring to an external tube, the other end being fixed by an end plate to a concentric inner tube which can be moved axially and has holes within the space limited by the spring, the end plate and a sliding joint. Filter is esp. used in automatic analysis appts., to eliminate solid particles from the samples of fluid. The filter is less effected by deposits of solids and is more readily cleaned without dismantling the existing appts. The rate of filtration can be altered by regulating the distance between the spirals, the filter differing in this respect from conventional screens in which the rate is fixed by the mesh.
