Patent FR-2455160-A1 (FR)
IPC: E06B9/80
Filed: 1980-04-25
Abstract: Known roller shutters have bulky, not very accurate control devices. The aim of the invention is to reduce the space requirement of the control device and increase its accuracy. To this end, the electric drive motor of the winding-up roller is switched off in the open and closed position of the roller shutter with the aid of in each case a limit switch (E1, E2) which is controlled by an associated roll counting mechanism (Z1 or Z2). The first counting roll of each roll counting mechanism is gear-coupled to the winding-up roller via a drive gear-ring (A1) and a gear wheel (27). The last counting roll of each roll counting mechanism (Z1 or Z2) has a switch-actuating member (28) and carries out only a partial rotation of less than 360 DEG for the greatest possible unwinding and winding-up path of the roller shutter. The entire control device can be accommodated in an end-side bearing housing (9) of the roller shutter.

Title: Microwave welding of dielectric materials using metallic strip - uses metallic cpd. which absorbs microwaves to heat plastics film permeable to microwaves
Inventor: BELLAVOINE ROBERT
IPC: B29C65/14
Filed: 1980-09-08
Abstract: Two films of a dielectric material, such as various plastics, are welded by placing a strip of a material which heats when exposed to microwaves between the overlapping edges of the dielectric sheets, and exposing the joint to microwaves. This technique is suited to on site assembly of large scale plastic protective films such as those used to line the walls of an artificial lake. The two sheets of plastic film to be joined (1,2) are placed so they overlap each other and a strip (3) pref. of copper powder, ferrous oxide, manganese oxide, or carbon black placed between them. A microwave generator (4) with a suitable antenna and shielding (5) is placed over the joint and when activated the microwaves heat the jointing strip (3), fusing the plastic around the strip.

Title: Automatic dispenser for e.g. cash, cheques - has tiltable platform positioned within chamber forming purge device associated with microprocessor
Inventor: GUIBORD RONALD D
IPC: G07D1/00
Filed: 1980-12-10
Abstract: The banknote dispensing system includes an operator panel having a keyboard for initiating transaction requests, and a dispensing chamber (58) adjacent to the panel for receiving banknotes dispensed by feeders (52) and a transporter (54) in response to an operator request. A lockable access door (40) enables the operator to gain access to the chamber to remove dispensed notes. A tiltable platform (60) positioned within the chamber forms purge device for discharging dispensed notes from the chamber under predetermined purge conditions detected by a microprocessor within the system. The microprocessor calls for a purge operation when it has been determined that the operator has either failed to remove dispensed notes or has left notes within the chamber. A purge operation may also be performed as a result of a system failure, such as a power outage or a counting error occurring during a dispense cycle; or when a foreign object is detected in the dispensing chamber as a result of vandalism.

Title: Continuous steam cooker for open cans of fish etc. - has modular construction for range of throughput capacities with fixed cooking time (PT 26.2.82)
Inventor: MIRANDA CANDIDO RODRIGUEZ
IPC: A23B4/005
Filed: 1981-05-25
Abstract: A continuous steam cooker for fish etc. in open top cans or similar containers comprises four modules connected in series, i.e. module 1: automatic infeed section in which trays of cans are transferred from a transverse feed conveyor to supports attached to a cooker conveyor chain. Module 2: a steam cooking chamber through which the conveyor chain carries the cans of fish. After passing through the steaming chamber, the cans are conveyed through a hot air grilling and drying zone; module 3: an automatic discharge section in which the trays of cans of cooked fish are withdrawn from the cooker chain supports and placed on a transverse discharge conveyor which passes the cans to a lid seaming machine. Module 4: a washing section for cleaning the chain supports before they are reloaded. The washing module is in a passage located underneath the cooking module. The passage houses the return run of the cooker conveyor chain between the discharge and in feed modules. Pref. the discharge module is of similar construction to the infeed module and both employ mechanical linkages actuated by pneumatic cylinders. Each module can be constructed to different lengths to provide cookers of different throughput capacities which still give the same cooking period.
