Patent FR-2333747-A1 (FR)
IPC: B66F9/14
Filed: 1976-12-03
Abstract: SLIDER/ROLLER SIDE SHIFTER FOR USE ON A FORKLIFT TRUCK A side shifter frame unit for mounting on a forklift carriage includes sliding bearing shoes disposed in notches formed on a lip of an upper bar of the carriage.  The sliding bearing shoes have a rear surface inclined at an angle steeper with respect to the horizontal than a front upper bar carriage lip surface so that a side shifting unit will not tend to "climb" when the unit is laterally displaced.  A bottom plate of the side shifter utilizes a rolling disc rotatably mounted within a housing for rolling contact with a lower bar of the carriage. The rotatably mounted disc has its axis of rotation directed inwardly and inclined to the face of the lower bar.  In one embodiment of the invention, a side shifter actuator is secured to a bracket which is demountably suspended from the upper bar.

Title: Pompe a cylindree variable avec limiteur de puissance
Inventor: ADAMS CECIL E
IPC: F04B1/30
Filed: 1977-08-03
Abstract: Pompe à cylindrée variable avec limiteur de puissance. Le limiteur de puissance pour la pompe comprenant un piston axial, procure un réglage simple de la puissance maximale que cette pompe peut fournir et ajuste automatiquement le produit de la pression de travail par la cylindrée maximale, afin de maintenir la puissance à sa valeur fixée. Le limiteur de puissance fonctionne en diminuant la cylindrée de la pompe quand la pression du fluide de travail dépasse celle du réglage d'une soupape séquentielle. Une soupape compensatrice assure un écoulement constant du fluide à travers un orifice de limitation de puissance et permet de faire varier avec précision le réglage de la soupape séquentielle.

Title: Expansive evaporation for sea water desalination - with one of two side streams in last stage controlled in temp. and flow rate for use as make=up water
IPC: C02F1/06
Filed: 1977-08-11
Abstract: A multistage expansive evapn. system for the desalination of sea water has at last heat dissipation section in which the fresh sea water, entering through pipe passes in two separate streams through separate heat exchanger coils. Only the second side stream is controlled as regards flow rate to acquire prior to entry into the section with the enriched brine the same temp. as the brine. The other side stream is merely used for cooling and is discharged into the sea. This compensates for any detrimental effect of temp. fluctuations of the sea water used for the heat exchangers of the last stage. The yield of fresh water is optimised and there are savings in capital and operational costs.

Title: Steam generator for removing wall paper - incorporates water feed tank with pressure equalisation, allowing continuous operation
IPC: B44C7/02
Filed: 1977-12-05
Abstract: An appts. for removing wall-paper by means of steam comprises a boiler resting on a base provided with a burner and surmounted by a water feed tank. The water feed tank is connected to the boiler by a feed pipe for charging water to the boiler and by a pipe admitting the steam pressure of the boiler into the feed tank. The burner is pref. fed by liquefied gas, e.g. butane or propane. The boiler, the base and the feed tank are pref. cylindrical. The boiler may be of the fire-tube type or may be double-walled. This avoids disadvantages of existing equipment for using steam for removing wall-paper, e.g. that they have no means of refilling the boiler. The machine can be used continuously and avoids lost time for refilling. The appts. may be used also for plucking poultry; removing posters; sterilising; softening leather for making foot-wear; softening wood for curving; and disinfecting.
