Title: Sand-filled cartridge fuse - has transparent body which indicates when the fuse has ruptured
IPC: H01H85/30
Filed: 1974-03-29
Abstract: This cartridge fuse has a transparent or translucent, hollow and cylindrical body (2) sealed by end caps that form contacts for the fusible link (1) that is suspended between them. The link is surrounded by sand and has a layer (8, 9) of lead and tin alloy and aluminium or magnesium deposited upon it. When the link ruptures, the vaporisation of the metals causes a deposite to permeate through the sand and coat the inner walls of the body. As these are not opaque, this deposit gives a visual indication of fuse rupture.

Title: Yarn false twist spindle - with twist peg inside bladed rotor driven and floated by air
Inventor: KIMOTO HISASHI
IPC: D02G1/06
Filed: 1974-06-28
Abstract: Hollow shaft of rotor with turbine blades houses a twist peg, a rotor casing being romed with inlets for directing air to both ends of a stepped centre portion of the shaft to float the rotor, and also against the centrally located blades. Further openings in the casing project air from the yarn inlet side of the casing in directions inclined towards the ingoing yarn (to cool it). Pref. >=1 axial face of each blade is of magnetic material, and a magnet in the casing opposite that face so that a magnetic force opposes any propelling force imposed by the running yarn in the direction of the rotor shaft axis. High speed air turbine twister is obtd. which cools the yarn and has low air consumption.

Title: Measuring vol. of pipeline gas under pressure - by measuring instantaneous pressure and measurement period
IPC: G01F1/38
Filed: 1974-09-24
Abstract: Gas under pressure in a pipe flows in a tubular diaphragm to a cavity with a deformable membrane to which a shutter is attached. The shutter determines radiation received by a photodiode from a source. The photodiode output is amplified and passed to an oscillator whose output frequency depends on photodiode excitation. The pulses are counted in a counter circuit comprising bistables. Light intensity of one lamp indicates pressure excerted on the membrane and a second lamp indicates end of measurement. The diodes may be replaced by a mechanical transmission fixed to the membrane so as to operate a potentiometer slide.

Title: Polishing substrates used for electronic circuits - using laser beam which melts thin surface layer on moving substrate
IPC: H05K1/03
Filed: 1974-12-03
Abstract: At least one zone of the non-uniform surface of a solid is treated by a beam of radiation which is at least partly absorbed by the solid. A beam focussed to provide sufficient energy is used for the local melting of the surface of the solid; but the exposure time is too short to convert the material to a gaseous state. The beam is pref. a laser beam focussed along a line, and the workpiece is moved w.r.t. the line so that it is polished by local surface melting. The workpiece may have a m.ptp. or melting range and is esp. a ceramic, e.g. sintered alumina, or a glass. The pref. appts. includes a CO2 laser using a cylindrical lens or mirror to focus the beam along a line which is at 90 degrees to the direction of travel of the workpiece. The process and laser can be used, e.g. for the polishing of alumina substrates used for the film electronic circuits. Alumina substrates normally have a surface roughness of 0.2-0.5 mu m which is in adequate for some thin film circuits. The invention produces a surface roughness 0.05 mu m.

Patent FR-2299597-A1 (FR)
Title: Gas lighter flame adjusting mechanism - has notched disc with rotation limited by pin in blind hole
IPC: F23Q2/173
Filed: 1975-01-31
Abstract: The mechanism allows the setting of the angular limit regulating the height of a gas lighter flame by the manufacturer, taking account of the mean temperature where the lighter will be used, so that the user can only vary the flame height within the angular limitations. The angular limit is determined by the interval between the sides of a notch formed in a pivoting disc. This fits in the lighter body against a portion having a series of blind holes (9), one of which accommodates a stop pin (12) extending between the sides of the notch and thus limiting the amount for which the disc can be rotated and the amount by which flame height can be adjusted by the user.
Patent FR-2302145-A1 (FR)
Title: Paint roller with paint pump - has paint fed to space between double walls of roller and employs drive gears
IPC: B05C17/03
Filed: 1975-02-25
Abstract: The paint roller has a pump arrangement mounted on a tube which dips into a paint pot, and which distributes the paint to the bristles in the roller. The paint travels through the tube to a chamber at the far end of the roller, leaves the chamber through holes at the end, and passes into the space between the double walls of the roller, through farther holes on the outer wall to the bristles. At the same time, a crank arrangement drives a set of gears terminating in the other end of the roller, to rotate the roller as the paint is delivered to the bristles, to ensure an even distribution of paint. The paint feed tube passes through the centre of the gears.

Title: Automatic orientation of fruit for mechanised size grading - partic. unsymmetrical fruit like apples pears and tomatoes
IPC: A23N4/14
Filed: 1975-04-10
Abstract: The device comprises two smooth, parallel jaws symmetrically spaced on opposite sides of a median, vertical plane towards which the lower edges of the jaws converge slightly. The jaws have a series of paired concavities, each pair providing a pocket in which a fruit lodges when loaded from above. The jaws are then progressively opened, first to suspend a pocketed fruit with its centre of gravity handing below the jaw-gripped dia., and then to release the fruit thus orientated. The tops of the concavities are pref. chamfered to provide a lead for fruit entering a pocket. Positioners can be fitted to a carrier chain to be run in alignment and synchronisation with a size-grading conveyor, the chain pref. being operated from the conveyor drive. The size-grading appts. is not misled by varied presentation of the fruits.

Title: One-piece plastic moulded injection needle container - has friction exerting jaws for retaining the needle assembly and seal membrane for ensuring sterility in storage
IPC: A61M5/00
Filed: 1976-03-17
Abstract: A container for an injection needle has a tubular body pref a plastic moulding provided with an access opening at the end adjacent to the fixing hub of the needle. The part of the body surrounding the fixing hub of the needle has a circular cross section. The known design is modified to provide projections pref. flexible jaws moulded integrally with the container at equal angular spacing on the rim of the container opening. These projections are in slightly frictional engagement with the needle fixing hub when this is on the container in order to prevent the needle falling out under the action of gravity. Construction not only ensures the retention of the needle but provides sufficient frictional resistance to enable the needle hub to be directly pushed onto the injection syringe and after use drawn back into the container so that this and the used needle can be thrown away without the user touching it.
