Title: Automatic insertion of container caps - has re-usable caps for containers which are automatically tightened by belt drive units
IPC: B65B7/28
Filed: 1974-12-04
Abstract: container tops are fed from a magazine in a synchronised mode onto containers being fed on a conveyor belt. Once a cap is located in position on a container the container is passed between two small endless belt drive units that impart a rotational motion to the container. A motor driven endless belt contacts the cap at a certain location and a turning movement is imparted to secure the cap. An alternative method replaces the motor driven belt with two cone shaped rollers that hold the cap on the container and rotate it at the same time.

Inventor: BONIS MAURICE
IPC: H01L21/337
Filed: 1974-12-24
Abstract: Method of making a field effect semiconductor device with vertical channels comprising a first epitaxial deposition on a monocrystalline wafer of semiconductor material of first conductivity type, a localised diffusion in one region of opposite conductivity type donant, constituting the grid of the device, and a second epitaxial deposition of first type conductivity, is characterised in that after the first deposition a localised prediffusion deposit is effected in the form of the said grid and this deposit is selectively covered with an oxide layer prior to effecting the second epitaxial deposition step, the material grown on the oxide layer being polycrystalline. The device is then subjected to a deep oxidn. step, reaching the grid, and the oxide layer formed from the monocrystal is removed and a surface diffusion giving first type conductivity is effected in those parts based of monocrystal. The cross sections of the vertical channels are maximised, their lengths minimised and the capacity between the grid and source is minimised while the breakdown voltage between the grid and source is maximised.

Title: Fluid flow determination using thermoresistances - has electrical heating pulses applied to resistances in flow channels
Inventor: CALVET PIERRE
IPC: G01F1/68
Filed: 1975-04-16
Abstract: The method of measuring the mass flow of a fluid flowing in a known direction along a channel (11) whose walls (12) form heat sinks involves placing one or more thermoresistances (10) in the flow, applying an electrical heating current to these thermoresistances, and determining the thermal transfer within the fluid. The thermoresistances are actuated so that an alternating flow is set up superimposed upon the main flow. This is achieved by applying electrical heating current pulses to the thermoresistances at regular intervals, the thermal transfer being determined during the time intervals between the heating pulses. A diaphragm (13, 14) pierced with a slit or an orifice is placed in the flow to ensure that the flow velocity on the sensor is greater than that in the remainder of the channel. The diameter of the slit or orifice is approx. 10 mm.
