Patent FR-2124520-A1 (FR)
IPC: B66F9/14
Filed: 1972-02-07
Abstract: 1335879 Lift truck attachments R E BARKER & CO Ltd 2 Feb 1972 [8 Feb 1971] 4117/71 Heading B8H An attachment for a lifting vehicle, e.g. a fork lift truck which provides side shift of the load engaging means thereon to either side of the truck comprises a rear frame 1 having members (4), Fig. 1 (not shown), for securing the attachment to the carriage plate of the lift truck, a midframe 2 hingedly mounted at 12, 16 to a carriage plate 15 which is mounted for movement along the rear frame 1, and a front plate 3 on which load handling forks (9) are mounted, the plate 3 being mounted on a carriage plate 82 for movement along the midframe 2. The midframe 2 is movable about hinges 12, 16 towards and away from the rear frame 1 by means of hydraulic rams 18, 19, pivotally connected to the carriage plate 15 and midframe 2 and its lateral movement along the rear frame 1 on the carriage plate 15 is effected by means of fixedly mounted rams 65, 67 having pulleys mounted on the free ends of their respective rods about which pulleys runs a chain 71 which is connected to the carriage plate 15. The front plate 3 is movable about hinges 80, 81 by means of hydraulic rams 85, 86 pivotally connected to the front plate 3 and to the carriage plate 82, the plate 82 being movable along the midframe 2 by means of a second pair of fixedly mounted rams 98, 99 which engage a chain 104 connected to the carriage 82. In operation of the device, a pivotal movement of the midframe 2 and thus the front plate 3 and the forks mounted thereon away from the rear frame 1, the carriage plate 15 simultaneously moves inwardly along the rear frame 1 thus maintaining the forks within the lateral sides of the attachment. Similarly, if side shift of the forks to the other side of the attachment is required pivotal movement of the front plate 3 away from the midframe 2 occurs simultaneously with lateral movement of the carriage plate 82 across the midframe 2. Such simultaneous movements are achieved by means of sequence valves (151-154), Fig. 9 (not shown), connected into supply conduits (145, 146) leading from the hydraulic system of the fork lift truck to the four pairs of rams referred to above, control over the supply of hydraulic fluid to the said rams being effected by means of a lever (141) and its associated push button (143).

Title: Moulding gas turbine inner liner - from glass using mould having retra-ctable walls to relieve pressure on glass during cooling
IPC: C03B32/02
Filed: 1974-05-06
Abstract: In moulding large complex hollow glass articles, use is made of a mould having pairs of walls cooperable when clamped together in a closed position to define a mould cavity including a core carried by one pair of the walls. After introducing a charge of molten glass into the cavity and pressurising it, the pressure is subsequently relieved by withdrawing at least the core-carrying walls so that differential thermal contraction and expansion of the glass and the mould can take place to prevent fracture of the article. The technique is particularly adapted for making gas turbine inner liners which can subsequently be heat treated to convert the glass to a crystallized glass-ceramic material.

Title: Composite piston for I.C. engines - is bolted to lower section with counter threaded connecting ring
IPC: F02F3/00
Filed: 1974-11-15
Abstract: The piston crown is connected to the piston skirt by bolts which pass through holes in the piston skirt and a counter threaded connecting ring of thin metal to screw into threads formed on the outside of the combustion chamber trough. The advantage gained is the avoidance of welding and the fact that the piston may be dismantled for cleaning purposes. Annular cooling oil flows through a space in piston crown, passes through grooves in a further cooling oil space in the light weight metal skirt, and leaves through a central aperture.

Title: Printing block giving realistic reproduction of artists style - made as relief negative or original painting
IPC: B41C3/00
Filed: 1974-12-13
Abstract: A printing block is produced by the following method: a temporary base is coated with a coloured substance, pref. by painting on or drawing on, and then a layer of powder is sprinkled and embedded into this coating either while it is still soft or after it has been re-softened; this layer of powder is then covered with a matl. to form the block itself, this being sufficiently soft for the top surface layer of the powder to become embedded in it; after this block matl. has hardened, the temporary support, coloured coating and the lower powder granules are removed, leaving only those which are embedded in the block matl. The block matl. is pref. applied in a flowing condition, and the coloured layer may be removed by finally washing it out. The resulting effect in a picture produced from the block is an extremely realistic imitation of the original, indicating the style of the artist.

Title: Operational interval delay in boiler with separate hot water heater - has system of inter-operating thermostats to sense water and boiler temps, control circulation and burner operation
Inventor: FRANSSON EGON BROR GILLIS
IPC: G05D23/275
Filed: 1975-09-17
Abstract: A device for the extension of the operating time interval of a boiler with separate hot water producer has a primary operational thermostat (13) which connects the circulating device (19) when the water temp. in the boiler equals or is less than the cut-out temp. of the hot water producer thermostat (16). The circulating device (19) then functions until the water temp. has fallen below the cut in temp. of the hot water producer thermostat (16). From this point the thermostat (16) controls the operation until the procedure is repeated on elevation of the water temp. in the boiler. A second operational thermostat (20) with temp range exceeding that of the hot water production thermostat (16) operates the boiler heating device between specific levels.

Title: Metal ties for wall shuttering - protrude through the shutter for use in correcting alignment
Inventor: MICHELET ANDRE
IPC: E04G17/14
Filed: 1975-09-11
Abstract: Wall-shuttering made of wooden planks employs metal ties which allow any errors in alignment of the shuttering to be quickly and easily corrected. The ties consist of cross-pieces arranged horizontally in vertical planes internal and perpendicular to the shuttering and with the ends extending out through the walls. Keybolts are placed vertically on the outside of the walls ensuring the joint between cross-pieces is located in the same vertical plane. At least one of the ends of the cross-piece which protrudes through the walls is shaped in such a way that lengthwise pressure can be exerted to correct the alignment of the planks.
