Title: Device for sharpening pencil leads to required sizes
IPC: B43L23/00
Filed: 1984-01-23
Abstract: Device for sharpening the leads of a propelling pencil. The invention relates to a device for sharpening pencil leads in two symmetrical planes to a predetermined thickness. It consists of a housing 1 having notches 4 for adjustment purposes, an entrance block 3 in which the lead is engaged, and two abrasive surfaces 2 for sharpening the lead. The user adjusts the length of the lead by means of one of the notches 4, inserts the lead into the entrance block 3, moves it back and forth to sharpen the lead on the two inclined abrasive surfaces until the propelling pencil can advance no further and sharpening stops. The device according to the invention is particularly intended for the sharpening of leads of propelling pencils by professional draughtsmen.
Patent FR-2560053-A1 (FR)
Inventor: GUITEL JEAN-CLAUDE
IPC: A63C7/10
Filed: 1984-02-29
Abstract: A heel-retaining device for a ski binding in which a ski brake is integrated with the device and in which the heel-holding member is carried by a rotary plate located beneath the heel of the ski boot. The rotary plate has a large opening within which are mounted the pedal for operating the pivotal arms of the ski brake together with the adjacent end portions of the braking arms. The pivot-pins of the braking arms are located below the level of the rotary plate. An upward displacement of the brake-operating pedal at the time of lifting of the ski-boot heel is not liable to interfere with the free rotational movement of the rotary plate and the components carried by the plate.

Title: Optoelectronic device for the accurate lateral inspection of the unwinding of a web of material such as paper
IPC: B65H23/02
Filed: 1984-06-05
Abstract: The subject of the invention is a device for optoelectronically detecting and indicating the lateral movement both of the edge of a sheet of paper and the edge of a watermark made in the paper or the edge of a fabric. It comprises a transverse row of optical means such as fibres 5 housed in a case 4 and arranged at the edge of the vicinity of a face of the web of material coming from the roll 1 in order, in this example, to be divided into three webs 3 with the aid of cutters 2. A light source is positioned opposite the row of fibres 5, the web of material being interposed between the source and the aforementioned row so that the centring during the unwinding is detected by occultations or illuminations of the optical means 5. These means transmit to photoelectric cells the light information which is converted thereby into electrical signals transmitted to analyser means, enabling the possibly required corrections to be carried out. Application in particular to the paper and fabric industry.

Title: Apparatus intended for accurately measuring out liquefied gases and various fluids
IPC: F17C13/02
Filed: 1984-06-29
Abstract: Apparatus intended for the treatment of wines during formation or preservation, in order to overcome or treat any effects which may be caused either by microbical origin or physico-chemical accidents and accidental bad tastes. The apparatus comprises a bottle 1 of nitrogen in this particular case (or any other neutral gas depending on the fluid to be injected) at its filling pressure which delivers its gas at the ''chosen optimum operation pressure'' by means of a pressure releaser regulator 2 equipped with a valve. This gas penetrates into the gaseous space of the SO2 (or fluid used) bottle 3 through the gaseous phase path of the cock of this bottle (two-way cock). The liquefied SO2 (or fluid to be injected) contained in the bottle is propelled by means of the plunger 3 bis equipped with its purifying filter 15 towards the distribution station 4. The line running towards the station is equipped with a degassing valve 15 bis and with a stop valve 14. The fluid runs through the station by passing through the following equipment : - a control manometer 5, a purifying filter 6, a calibrated regulating nozzle 7, an electrovalve 8 controlled by the timer 9 regulating the injection time depending on the need. The outlet line 10 delivers the fluid to the medium to be treated. An auxiliary line 11 equipped with two stop valves 12 and 13 makes it possible to carry out a degassing cleansing after use.

Title: Device for perception and analysis of sounds by tactile or optical means
IPC: G09B21/00
Filed: 1985-02-19
Abstract: The invention comprises an apparatus consisting, in its input, of a sensor of sounds by means of a conventional microphone 1, and in its output of electromechanical or optical transducers of unspecified but sufficient number to allow correct sound definition 10. The signal picked up is, after amplification, processed so as to be analysed into its component frequencies. The latter are converted into signals applied by specified electromechanical or optical transducers respectively; each of the latter conveys, for a specified narrow frequency band, a pressure which is exerted on a fixed point of the skin, or a spatially fixed luminous flash enabling the subject thus equipped to discern the intensity thereof. The assembly thus constituted provides an image of the sound, either tactile or optical, making it possible after training, to "hear" with all the desired sensitivity and selectivity, the various sounds normally perceived by any non-defective hearing.
