Title: Protective bumper for small fork lift truck - has two L=shaped shutters associated to support and concealing wheels, cutting off motor supply when displaced e.g. in collision
Inventor: LUCE PIERRE ALEXANDRE LOUIS
IPC: B66F17/00
Filed: 1981-02-06
Abstract: The bumper surrounds the base of a motor driven fork carrier and comprises two L-shaped components. These extend around the back and two sides of the carrier frame, concealing the wheels of the carrier. They are elastic and are supported on flexible supports on the sides and on springs on the back. A further component of the bumper overlaps the joint between the L-shaped sections along the back of the carrier. The bumper support includes two switches which are activated when the bumper is knocked, to switch off the driving motor. The bumpers help to prevent the operator's feet being caught under the wheels, and also serve as sensors detecting collision with any object to shut off the supply to the driving motor.

Patent FR-2479024-A1 (FR)
IPC: D21B1/06
Filed: 1981-04-01
Abstract: A device for driving transporting rollers on comminution machines is described. Driving is performed by individual oil-hydraulic motors which are connected in series and can be driven by a variable quantity of oil in opposing directions of rotation. The quantity of oil is fed by a hydraulic pump to which a valve which controls the quantity of oil fed is assigned. The pump is coupled to a blade drum or disc in such a way that the speed-of-rotation ratio between the drum or the disc and the pump can be kept constant. As a result, it is ensured that the transporting rollers feed the material to be comminuted at a speed which enables a uniform particle size to be produced during the cutting process. This particle size can be adjusted by virtue of the fact that the quantity of oil fed by the pump can be varied by means of a valve, as a result of which only a portion of the fed quantity of oil is supplied to the oil-hydraulic motors.

Title: Di:fluoro-methane-sulphonic acid - useful as catalyst, prepd. from sodium salt
Inventor: LANGLOIS BERNARD
IPC: C07C309/06
Filed: 1981-04-29
Abstract: Difluoromethanesulphonic acid of formula CHF2SO3H (I) is new. (I) can be used as a substitute for CF3SO3H, esp. as a catalyst for hydroxylation, Friedel-Crafts condensation, olefin isomerisation, esterification, nitration, etc. (I) can be prepd. by a process which is much easier to operate industrially than the known processes for preparing CF3SO3H. The process comprises (a) mixing 100% H2SO4 in an at least stoichiometric amt. with solid Na difluoromethanesulphonate (II) contg. 0.5-1 mole H2O/mole, and distilling the mixt. under vacuum to obtain hydrated (I), and (b) mixing the hydrated (I) with oleum having an SO3 content of 10-40 wt.% in an amt. sufficient to supply the stoichiometric amt. of SO3 w.r.t. the amt. of H2O in the hydrated (I), and distilling the mixt. under vacuum to obtain anhydrous (I).

Title: Air circulation arrangement for periphery of cooking plate - has air drawn from beneath plate and forced through peripheral holes and into cooker hood
IPC: F24C15/20
Filed: 1981-05-22
Abstract: The unit sets up a curtain of clean air around a cooking plate, by operating in conjunction with an overhead cooker hood having an integral extractor fan. Clean air is drawn in through an inlet duct and is transported to a circulation fan fitted centrally beneath the cooking plate. The air is then circulated through a chamber formed by the cooking plate on one side and an attached closed box on the other, and is thus preheated before being exhausted through an array of holes around the outer periphery of the cooking plate, to be drawn up by the extractor. Orifices are situated about the periphery of the cooking plate to allow the passage of the forced air.

Title: Radiological image analyser for heart organ diagnosis - uses computer and light-pen with two stored displaced images to trace area and thus calculate position, area and volume
Inventor: HAENDLE JORG
IPC: H04N5/32
Filed: 1981-06-18
Abstract: The appts. is used to evaluate geometrically radiological images and consists of a radiation generator tube (1) a luminance amplifier (5) a television camera, a frame store and a co-ordinate generator to mark out a contour on a monitor. Two radiological images are generated with a lateral displacement of the radiation source between them and superimposed on the monitor (11). A computer connected to the coordinate generator or light pen is used to calculate from the co-ordinates of contours and the known displacement the position and hence the dimensions and true volume of the traced organ (4). Alternatively, the displacement may be achieved by moving the luminance amplifier or switching sources. The monitor has a hard copy image printer (12). Filmed images can also be analysed by using a television camera. The system permits the simple, direct and automatic calculation of volume from a contour tracing for heart diagnosis. From the image spacing the distance of the organ from the luminance amplifier and the magnification factor is calculated.

Title: Boron nitride prepn. contg. compact wurtzite-type and cubic phases - using double treatment at high pressure and temp., so polycrystalline prod. has high mechanical strength
Inventor: ZHDANOVICH G M
IPC: C04B35/5831
Filed: 1981-06-30
Abstract: Boron nitride with a hexagonal crystal structure (HBN) is pressed using 3-8 kbars to make a blank. The blank is subjected to 100-150 kbars at 290-1500 deg.K., so at least 15 wt% of the HBN is converted into the compact modification possessing a wurtzite-type crystal structure (WBN). The pressure is then reduced to 40-90 kbars while the temp. is increased to 1600-3200 deg.K., so the HBN is completely transformed into polycrystalline compact phases, viz. HBN and cubic boron nitride (CBN). The initial blank pref. contains by wt. 0.1-0.8% of addns., esp. Al, B, transition metals, or nitrides, carbides, borides or carbonitrides of transition metals. The polycrystalline prod. obtd. has a much higher strength than similar conventional material.

Abstract: It has an outer gear wheel (5) and, mounted eccentrically with respect thereto, an inner gear wheel (7), which gear wheels on one side mesh and on the opposite side are separated from one another by a filler piece (9a). Debouching in the two circumference sections located in between there are a feedline (10) and a discharge line (11). So as to use a gear pump of this type for low-viscosity liquids and high discharge pressures, the outer gear wheel (5) runs in a bush (6) which in the outlet zone of the feedline and discharge line (10, 11), respectively, has one passage orifice (12, 13) each, these having a smaller cross-section and being further apart in the circumferential direction than the outlets of the feed and discharge lines (10 and 11, respectively). In addition, the outer gear wheel (5), which is fashioned as a crown gear, and the pump casing (1) have arranged between them in an axial position a balancing disc. This has the pump fluid acting on it on both sides and serves to support the crown gear (5) axially with respect to the casing (1).
