Title: Brake shoe for packaging machine - which has a central support and locking tag
IPC: F16D65/06
Filed: 1974-06-20
Abstract: The friction pads (2) which come into contact with the shaft (6) are supported on the shoe (1).

Title: Distillery plant with controlled steam heating - using thermo-probe at inlet and condensate float switch at outlet of cooler
IPC: B01D3/42
Filed: 1974-07-17
Abstract: A distilling plant includes a still with a cooler and a steam heater, controlled by two parallel independent valves for the steam. A thermoprobe between still and discharge initiates a closing movement of one valve before the temp. expected at that point has been reached. A float in the discharge of the cooler senses the formation of alcoholic condensate and actuates through a float switch the other valve. System relieves the operator from the manipulation of the heating input. The full input is applied during heating up; the input is accurately changed to control the quality of the distillate and to keep the first runnings small.

Title: Adjustable travelling mine supports - has hinged arms and U-shaped telescopic roof supports adjusting to gallery height for protection
IPC: E21D23/00
Filed: 1974-10-24
Abstract: The mine support system includes a set of travelling roof supports acting as shields which can be adjusted to suit the height of the gallery, using sledges which rest on the floor, onto which are hinged U-shaped sheets members (12, 13) which support in turn upper U-shaped sheets (15, 16) which can slide telescopically along them, with the roof support plates mounted on top by further hinged joints. The set can be actuated by hydraulic cylinders to swing down and allow the roof plates to be shifted while matching the height of the gallery, in sequence. The shallow U shape of the elements gives protection from falling material, the heights of the fixed and moving elements being suitably proportioned. Intermediate protection plates (14) can be fitted to cover the gaps between adjacent fixed U-shaped elements.
Patent FR-2307215-A1 (FR)
Title: Safety catch for hydraulic platen closure system - to depressure the traverse ram if a safety gate stays open
IPC: B29C45/84
Filed: 1975-04-11
Abstract: The device comprises a rod part of which is toothed to engage a rachet mounted on the gate and part of which forms a plunger traversing a hydraulic valve. Under normal conditions the plunger is located by a thrust pin so that part of the valve chamber is obstructed to isolate two hydraulic connections to the valve. If the platen moves while the gate is open, the ratchet on the latter restraints the rod sufficiently to shear the pin. Subsequent motion of the valve body (on the platen) relative to the plunger connects the hydraulic connection to relieve the pressure on the platen traverse ram, thus halting the platen motion. Device is suitable for guarding daylights on injection moulding machines etc.

Title: Silencer with filter at exit - has archimedean screw rotated by exhaust gases descaling interior of silencer
IPC: F01N1/18
Filed: 1975-07-16
Abstract: The silencer consists of a cylindrical casing (11) and an inner shell (12) with a layer of thermal insulation (13) trapped between the walls. A perforated drum (6) fits inside the two shells (12, 11). A shaft (1) with an Archimedean screw (2) is mounted in ball bearings (3) fitted in the end caps (18). The exhaust gases enter through the top pipe, and pass through the silencer forcing the Archimedean screw (2) to rotate. This rotation removes any scale from the interior surface. Together with other polluting constituents of the exhaust gases this scale is absorbed in the cartridge (15) fitted in the lower end of the silencer.

Title: Simple pipe hanger and clamp - has screw through bent clamp strip locking together ends of looped strip hanger
IPC: F16B2/06
Filed: 1975-09-05
Abstract: A cheap and simple pipe hanger and its clamp, made from strip metal, consist of a longer strip forming the hanger, made into a loop with two straight portions (10) extending from the loop, clamped together. The clamp is bent into a rectangular section tube to fit around the double thickness of the straight portions of the hanger, with the two ends (3, 4) overlapping and forming one of the longer sides of the rectangle. A hole is tapped through this overlap, and a screw (2) fitted, so that when the screw is tightened, it forces the two straight ends (10) against the back of the rectangle and bends them, so that they locate in a clearance hole (15) through the back of the rectangle.

Title: PVC based floor tiling with a heat conductive interlayer - to dissipate heat from cigarette ends etc. without damage
Inventor: NIVIERE JEAN
IPC: D06N7/00
Filed: 1976-02-13
Abstract: Composite sheet or tiles for floor coverings comprising a thin, wear resistant surface layer, and an intermediate layer of plastic material filled with metallic particles which can dissipate heat. The intermediate layer can dissipate heat from local surface hot spots, e.g. discarded cigarettes, to inhibit ignition, damage or thermal degradation of the surface or other layers. Use of highly heat resistant (and expensive) materials for the surface coating may be reduced or eliminated.
Patent FR-2313756-A1 (FR)
IPC: H01F41/077
Filed: 1976-06-04
Abstract: In the case of this device, a conductor track (1), which runs off a supply coil (2), runs over control rollers (3, 4) and deflection rollers (5) to the respective template (9) of a coil winder. This device is designed such that, in addition to producing coils of round shape, it also ensures correct winding of coils of polygonal shape. This is achieved in that a deflection shaft (5) is arranged spatially in front of the coil winder, which deflection shaft (5) is arranged such that it can pivot out laterally in an adjustable-height carrier (6) and can be deflected out in an axially limited manner against restoring forces, and whose vertical adjustment range extends approximately from above the running-on plane of the conductor track (1) to below the coil winder. In this case, the adjustment position of the deflection shaft (5) is selected such that the conductor track (1) is guided over the deflection shaft (5) from above when round coils are being wound and over the deflection shaft (5) from below, to the respective winding template (9), when polygonal coils are being wound.

Title: Explosive shell self destruction mechanism - has arm forced inwards by spring loaded levers when spin falls to low value
Inventor: CASTERA ANDRE
IPC: F42C9/18
Filed: 1976-09-22
Abstract: An explosive shell has a latch mechanism held in a locked position before firing, which is released after firing, and held in an inoperative position due to the spin of the shell during its course. The mechanism permits a self destructive action to take place when the spin falls below a given amount, indicating that the target has not been struck. The mechanism has four arms arranged in a rectangle, with hinge pins at their connection points. Attached to the hinge pin is a hooked arm which is released from a position with the hook fitting around a spindle at the middle so that it is flung outwards by spin. When the spin falls, it is returned to the inwards position, assisted by springs acting on the arms, but allowing the spindle in the centre to be operated, resulting in actuation of the explosive charge.

Title: Position monitor for mine roof support units - supplies, collects and stores data indicating advancing movement of props.
Inventor: DARBYSHIRE KENNETH
IPC: E21D23/14
Filed: 1976-12-13
Abstract: The equipment is for ascertaining relative positions of a row of roof support units in underground mines. It includes a device on some of the support units which supplies data concerning advancing movement of the support units and their bases. The supplied data is collected and stored by a remote control store, and is recorded as deviations between an actual and a predetermined advancing movement of the support units.
