Each wobble element consists of two portions which are rotatable relative to each other about a wobble axis extending transversely to the driving shaft. The connection of the wobble portions is provided via a collar which is fixed onto the driving shaft. The connecting rods of two diametrically opposing pistons are linked to each wobble portion which are guided in respective guideways extending parallel to the driving shaft.

Abstract: The hair clipper for use of removal of body hair prior to medical treatment or surgical intervention has a disposable cutter head (20). The cutter head comprises a base member (68), a stationary cutter member (60), a movable cutter member (62), a resilient member (64), a cover (66), and a drive coupling member (54). The base member (68) has teeth (110) to guide hair to the cutter teeth (76, 82). These teeth are configured to avoid the contacting, engaging and nicking of body skin. The simple and cheap cutter head is discarded after one use. This is facilitated by the clip segments (123, 127) for mounting the cutter head (20). The bird-like configuration of the hair clipper and the particular design of the cutter head (20) permits trimming of hair with a forward pushing stroke or a rearward drawing stroke.

Abstract: A method of making fibre mats as a starting material for pressed mouldings consists of applying a mixture of loose fibres and thermoplastic or thermosetting plastic binder onto a porous moving belt to form a first layer (4), then loosely laying a fabric, e.g. polyester fabric (12), on this first layer (after treatment as described below), and then scattering a second layer of fibres (16) onto this fabric. The resultant composite is then hot-pressed to activate the adhesive and form a mat for future hot-pressing into a finished product. The treatment of the fabric (polyesters) layer (12) consists of applying (6) to it, just before it is placed on the first layer (4), a liquid, heat-activatable finishing material possessing an affinity to the binding agents of the fibres.

Abstract: The opening and closing movement of a injector valve member (32) which closes and temporarily opens discharge orifices (52) communicating with the combustion chamber of an internal combustion engine, for example a diesel engine, is controlled by the fuel pressure in a control chamber (42) arranged at one end of the injector valve member (32). The fuel pressure in said control chamber (42) is controlled by means of two orifices (26, 38) communicated with one another. One of said orifices (38) is connected to a high pressure fuel inlet (12). The other orifice (26) is closed at one end by a solenoid operated pilot valve (72). Opening of the latter results in a single fuel jet passing through said orifices (26, 38) which causes the opening of the injector valve member (32).

Abstract: A flour recycling system includes a compressed air and vacuum head (27) placed over a bakery product conveyor line (26). Flour is removed from the product units (25) and is conveyed through a vacuum hose (14) to the inlet of a remotely located dual stage separator (46) in which the flour with entrained dough particles is subjected to a two-stage vacuum induced centrifugal separating process. Cleansed flour is drawn by vacuum through two fine mesh sifter screens (56) into two reclaimed flour tanks (61) each containing a vortex eliminator (62) and each having an air release bag (64). Reclaimed flour is delivered to storage receptacles (66) beneath the tanks through elongated flexible chutes (67) which can be tied off and closed at desired elevations.

Title: Force transducer with resistive gauges
Inventor: CHERBUY JEAN
IPC: G01L1/22
Filed: 1987-04-29
Granted: 1989-08-17
Abstract: A resistance-gauge force transducer comprises a resilient bar having one end adapted to be fixed to a stationary support and the other end subjected to the force to be measured. The bar carries two pairs of resistance gauges symmetrically disposed on both sides of the center of gravity of the bar. The direction of the lines of current of a gauge of one pair is parallel to the bar axis and perpendicular to that of the other gauge of the same pair. The gauges are electrically connected together so as to form a wheatstone bridge delivering a signal which is a function of the force applied to the end of the bar. The two gauges of one pair are adjacent and connected to each other in the wheatstone bridge. This arrangement renders the force transducer insensitive to thermal variations.

Abstract: A display device has a lattice of pixel elements each selectably settable. A method of operating the display device comprises the steps of receiving a signal representing a picture for display during a display period and illuminating the lattice to produce, during a first interval within the display period, a first light output from the lattice having a first predetermined colour characteristic and to produce at least one additional light output from the lattice. Each said additional light output has a different predetermined colour characteristic and a respective interval within the display period separate from the first interval. The method further comprises the step of time-multiplex addressing blocks of pixel elements a plurality of address times during each interval. The addressing step includes setting a group of blocks, the group consisting of a plurality of blocks spaced apart in the addressing sequence such that the blocks in the group form a series with adjacent blocks having a temporal separation in the addressing sequence exhibiting a geometric progression with a common ratio N being an integer equal to 2 or more. In this way, addressing of the lattice occurs simultaneously with its illumination by the appropriate colour, allowing a greater proportion of the frame time for the addressing operation so that additional addressing information can be utilised.
