Title: Device for introducing dosed quantities of powdery materials into a pneumatic fluid, and its application to a distributing bin
Inventor: LEGILLE EDOUARD
IPC: B65G53/46
Filed: 1984-04-07
Granted: 1987-07-23
Abstract: A device for introducing dosed or proportioned quantities of pulverized solid materials into a carrier gas stream is presented. The device comprises a housing which defines a flow chamber in the axial direction for the flow of pressurized fluid or carrier gas. The housing also has a side aperture therethrough. The side aperture is connected to a container holding pulverized materials. Coaxial inner and outer sleeves, at least one of which is capable of rotation, are located within the housing. The outer sleeve communicates with the aperture while the inner sleeve has an axial bore which provides a passage for the carrier gas. Upon rotation of a sleeve, slots provided on each sleeve will align and overlap with each other and with the aperture to define a variable sized passage between the container and axial bore whereby the pulverized material is delivered therethrough to the carrier gas stream. A third sleeve which is coaxial with the inner and outer sleeves and rotatable about its longitudinal axis is located between the housing and the outer sleeve. This third sleeve has a radial aperture corresponding to the side aperture of the housing. The third sleeve acts as a valve between the dosing device and a distribution tank.

Title: Heating food articles
Inventor: MASTERS ADRIAN GUY
IPC: A47J37/04
Filed: 1984-06-19
Granted: 1987-12-10
Abstract: The appts. has a heating chamber for receiving a food article and having a removable floor.  A cooling air flow is induced beneath at least a portion of the heating chamber located beneath the food article.  The fat which is excluded from food is swept away by the air flow to minimise the ignition of the  fat. The floor has a drip tray which is contoured to cause the excluded fat to flow to a collection position, and an upper plate whose upper surface in part defines the chamber. A lower plate spaced from the upper plate provides a boundary for the air flow.  A motor driven impeller induces the flow and is controlled in response to the temp. of the floor.  The food is carried through the chamber using a conveyor belt.  The food articles may be hamburgers.

Abstract: In a colour display device colour elements (17, 18, 19, 21, 22, 23) are built up with the aid of picture cells (2) from juxtaposed rows of picture cells which are driven by line electrodes (3). The resolving power in the horizontal sense is increased by building up the colour elements from picture cells of different rows of picture cells. The period t1 which is required for driving a colour element is split up into sub-periods 1/2 t1 during which period samples of the signal to be displayed (length to) are presented to the column electrodes (4). Since notably for LCD-TV there applies that t1 > to, these samples can be presented during a period which is longer than 1/2 to.
