Abstract: A hydraulic lifting arrangement for a lift assembly (11) on a materials-handling vehicle includes a working piston-­cylinder device (17) for raising and lowering the lift assembly, a reversible pump assembly (40) for operating the piston-cylinder device, and an electric motor for driving the pump assembly. The piston-cylinder device (17) is a double-acting device and has two working chambers (28,29), which are connected to the pump assembly by connecting pipes (46,47). The pump assembly comprises a first and a second hydraulic pump (41,42) having fixed displacements. The pumps are so arranged in the system that together they supply hydraulic medium to and receive hydraulic medium from solely the first chamber (28) where­as only the pump motor (41) supplies and receives hydrau­lic medium to and from the second chamber (29). The rela­tionship between the displacement of the first pump (41) and the sum of the displacements of both pumps (41,42) corresponds essentially to the relationship between the respective active piston areas in the second and the first chambers. Conveniently, a pressure-gas chamber (26) is arranged in the piston-cylinder device for biassing the piston (19) so as to enable the dead weight of the lift assembly and a given part of the load to be counter-balan­ced.

Abstract: La présente invention se rapporte à un dispositif d'alimentation en fil pour une machine à fil de coupe par électroérosion qui est capable d'effectuer, lors d'une opération d'usinage par décharges électriques, le retrait d'une courroie de transfert de fil à partir d'une position dans laquelle les fils sont connectés automatiquement, empêchant ainsi l'usure de la courroie et les fluctuations de la vitesse d'avance des fils. Afin d'effectuer une opération de connexion automatique des fils, on active un vérin automatique (27) pour un mécanisme d'alimentation en fil (16). Ainsi, une seconde courroie de transfert (15') se déplace d'une position de retrait vers une position de connexion automatique via un mécanisme de liaison parallèle (23, 25, 25', 25''), position dans laquelle la seconde courroie de transfert (15') vient se plaquer contre une première courroie de transfert (15). Lorsqu'on actionne un moteur (M2) pour faire tourner les deux courroies, un fil-électrode (5) tenu entre les deux courroies se déplace du côté amont d'un trajet du transfert du fil vers un côté aval de ce trajet pour compléter l'opération de connexion automatique. Lorsque le vérin pneumatique est ensuite désactivé, la seconde courroie de transfert retourne à la position de retrait grâce à l'action élastique d'un ressort (26), se séparant ainsi de la première courroie de transfert. En conséquence, le fil électrode et les deux courroies sont placés hors contact, empêchant ainsi l'usure du fil et les fluctuations de la vitesse d'alimentation du fil.

Abstract: A gate or cap (12) is provided for slipping over the front end of a needle shield to prevent body fluid in or on a contaminated used needle from flying out the front end of the needle shield either when the shield is being locked in place over the needle after use or during subsequent handling. The cap of the invention includes a front wall of a plurality of flexible flaps (16; 46; 62) which provide, simultaneously, for the required protec­tion while allowing passage of the needle (52; 72) through the cap with ease. The flaps may be in a depressed form to space the front wall or gate from the fingers of a user. There is no wiping of the needle as the needle moves through the cap into position inside the needle shield. No membrane penetration is required. As an additional feature, the gate or cap includes integral spaced annular ridges (14) for frictional gripping of the front end of the shield. It is within the purview of this invention that it may be formed as an integral gate for the front end of a needle shield (44, 66).

Abstract: In an apparatus for automatically cooling a workpiece (12) being manufactured by shape melting, a gas/liquid coolant mixture is pumped by a cooling head assembly (10) onto the external surface of the workpiece. Temperature data from temperature sensors (14, 16) and pressure data from pressure transducers (32) is fed to a computer control system (18) which regulates the flow of the gas and liquid coolant mixtures. The apparatus may be provided with multiple spray heads (24) which comprise the cooling head assembly (10) and have the ability to control the total rate at which coolant flows through the apparatus by individually controlling coolant and gas flow through each of the spray heads. If more cooling is desired, the computer control system (18) activates more spray heads (24) for flow, or it increases the flow rate through already activated nozzles. Both the number of spray heads (24) and flow rates through each spray head are variable, so the cooling capabilities of the apparatus are continuously variable over a wide range of total flow rates through the apparatus. A suction device which enshrouds the spray heads (24) extracts the heated and vaporised fluid from the vicinity of the surface of the workpiece (12).
