Title: Water tube boiler with separate tube banks - has sloping tube plates and hollow centre for reducing low resistance
IPC: F28D7/00
Filed: 1975-04-21
Abstract: The water tube boiler has a hollow centre and upper and lower tube plates which are arranged at an angle to reduce hydraulic resistance to flow at the inlet and outlet of the heat exchanger. The arrangement ensures also uniform distribution of heat carrier between the tubes and a uniform temperature field over the tube bank cross section and it is used in nuclear power plant. The tube plates (3, 4) of the tube banks are arranged so that gaps are left between the adjacent tube plates for unrestricted axial flow of heat carrier into the space between tubes in the inlet and outlet section of the heat exchanger. Each part of the upper and lower tube plates (3, 4) has a corresponding inlet header (6) and outlet header (7) for supply of heat carrier into the heat exchanger tubes (5).

Title: Public transport system linear motor track - has programmed control of vehicle speeds spacings and accelerations using pulsed voltage control
IPC: B60L15/20
Filed: 1976-01-26
Abstract: The linear motor track is for a public transport system in which the speed at each point is programmed with precision. This is achieved by motors having a fractional number of poles. The moving field between each motor and the adjacent motors is obtained by chaging the three phase connections. Programming at the start of traction is obtained by making the motor tractive effort greater than the vehicle need and pulsing voltage. These pulses are such as to give the acceleration desired. In virtually constant speed lengths there is an interval between the motors equal to the length of the vehicle or rake inductors.

Title: Two compartment mixing bottle for medicaments - for mixing contents just before use without outside intervention
Inventor: MILLER GALER JACOB
IPC: B65D25/08
Filed: 1976-07-27
Abstract: Two-compartment mixing bottle is provided with a central plug to isolate the upper and lower compartments from each other. the open end of the bottle is closed by a stopper which is traversed by a rod, made from glass or inert plastic material.
