Title: Ionic pulverization plant - with collector polarizing voltage measuring circuit
IPC: H01J37/34
Filed: 1972-09-07
Abstract: An asymmetric Langmuir probe is placed in the ionized gas plasma between the target and the collector. Its output is fed to an amplifier swept by a sawtooth waveform generator through the probe characteristic curve. After double differentiation, the amplified probe signal is fed to a bistable gate reset by the differentiated sawtooth. The bistable output is fed to an averaging amplitude detector whose second input is the sawtooth. A dc voltage measuring instrument is connected between the output of that amplitude detector and the collector. Automatic compensation for phase errors of the RF voltage in the shadow zones of the chamber increases accuracy of measurement.
Patent FR-2224728-A1 (FR)
Title: Spirally wound scraper rod - for automatic internal cleaning of heat exchanger tubes
IPC: F28G1/08
Filed: 1973-04-09
Abstract: Each tube of a heat exchanger contains internally a central rod spirally wound, such that the outside dia. of the spiral is the same as the inside diameter of the tube. The rods are attached via a support plate and piston to a screw jack or similar integral with the cover plate, which imparts an oscillating motion to the spirally wound rod. Thus the inside surface of the tube is scraped clean. The system is partic. useful in evaporators and heat exchangers with vertical and horizontal films, especially, but not exclusively in the food and chemical industries, and for highly viscous liquids or those liable to scale or form deposits.

Title: Universal arrgmt. for mounting machine tools in a tool store - which can automatically interchange tools with various ends to the same mountings
IPC: B23Q3/155
Filed: 1975-01-17
Abstract: The arrangement consists of a tool store in which tool holders are secured by a locking plate mounted on a key over which the tool mount is pushed. The locking plate can hinge about a central point. A pin is mounted on the tool store which is connected by a spring to a pin on the locking plate, so taht the locking plate can be held in any one of two positions. The travel of the plate in each direction is limited by a stop on the plate. In one position of the plate, the tool mount is locked in the tool store, in the second position of the plate, the tool mount with tool can be removed from the store. The locking plate is provided with a notch. an extension of a tool grip engages with this notch and pushes the locking plate in the unlocked position. The tool grip can now remove the tool and transfer it to the machine tool. After the previously used tool is returned to the store, the grip returns to its original position and pushes the locking plate back in the locking position.

Title: Heat treating textile by feeding in straight line through duct - which undulates and through which heated gas flows
IPC: F26B13/00
Filed: 1975-03-28
Abstract: A textile e.g. filament, yarn, sliver is heat treated (e.g. dried) by passage along a linear path through a duct which undulates. The separation of the troughs or peaks of the undulations are several centimetres. A heated fluid (gas) is passed through the duct in the same or opposite direction as the advance direction of the textile, so that the undulations cause the heated fluid to flow over the textile at an angle. By ensuring the heated fluid impinges on the textile at an angle the efficiency of the heating of the textile is improved.

Abstract: A device for controlled discharge of a strongly cohesive or agglomerative and not easily fluidised powder from a rigid vessel having a conical outlet consists of a rotating paddle whose shape fits that of the outlet cone and whose arms move near the walls of the cone, at least in its lower region. The paddle is connected by a power-transmitting shaft to a motor located inside the vessel and occupying only a small proportion of the cross-sectional area through which the powder flows. The device gives controlled, reliable outflow without contamination of the product and with comparatively low energy consumption.

Title: Centrifugal action grain grinding machine - has helical blades imparting swirling action to grain with min. heat generation
Inventor: PELTIER RAYMOND
IPC: B02C19/00
Filed: 1975-06-24
Abstract: The grain grinding appts. has a rotor plate (1) carrying helical blades (2), joined at their inner ends to a hub (4), and rotates about its axis (3), so that the grain is subjected to centrifugal force. In the spaces between the blades, due to the direction of rotation (6), the grain is subjected to a swirling action against the curved surfaces. This rotation of the grains and against one another at high speed gives an efficient grinding action. There is less wear and heat generation than in conventional grain grinding machines. The radius of curvature at the tips of the blades is equal to the distance between the tips.

Title: Electromagnetic clutch for computer drive mechanism - uses plate spring to ensure rapid disengagement when deenergised
IPC: F16D27/09
Filed: 1976-03-23
Abstract: The shaft (1) of the drive mechanism of a computer, carries a rotor (2) with a ring of teeth (3). These teeth match the teeth on the armature (7) which is normally held away from the rotor (2) by the compression spring (8). The armature (7) carries a disc (5) attached to it by a plate spring (6). When the clutch is energised the armature (7) is drawn towards the rotor (2) so that the disc (5) contacts the face of the rotor and the teeth (3) and (4) are interlocked. When the clutch is de-energised the plate spring (6) pushes the armature away from the rotor (2). This initial movement enables the weaker compression spring (8) to complete the disengagement of the teeth (3) (4).

Title: Free-wheeling cylinder bore grinder - is driven by oil under pressure which is fed into cylinder and thus avoids heavy drive gear
IPC: B24B33/02
Filed: 1976-05-31
Abstract: The grinding tool (5) with hydraulic pressure drive may be used to grind cylinder (3) bores. The grinder is driven by fluid under pressure traversing the interior of the cylinder (3) and, thus, has no direct connection to other machinery or equipment. The system obviates heavy mechanical drive gear and support equipment. the tool (5) may incorporate a mechanism deriving autonomous internal energy which is deployed to press grinding-segments against the cylinder bore. The system may also effect increment grinder rotation at the end of each pass and, thus improve the quality of the ground surface. The cylinder (3) may be sealed by end plates (1, 2) and be fed oil under pressure from a hydraulic power source. The grinding tool may inc. two sprung pistons enclosing a non-return valve, an inner closed oil circuit, several accumulators and a high-pressure valve.
