Title: Reinforcement of plastics storage tanks for use when buried - with external profile grooves to accommodate structural beams or hoops
IPC: B65D88/76
Filed: 1979-12-03
Abstract: A tank or reservoir, made of plastics material for use when buried and with internal access via one or more manholes provided on the top surface of the tank, is shaped with one or more transverse and/or longitudinal channels in the profiles of the upper surface so that the channels can accommodate external reinforcing beams supported by the side walls of the cavity containing the tank. Allows the tank walls to be made thinner and/or of more flexible matl. than could be used unsupported, e.g. polyethylene. For tanks of cylindrical cross-section, one or more annular channels may be provided to locate rigid hoops of reinforcing material (e.g. concrete) to enhance local radial compressive stiffness. Pref. the ends of the tank are shaped as flat panels which diverge from a horizontal plane aligned with the longitudinal axis of the tank to provide extra radial stiffness in that plane.

Title: Air pistol trigger operating mechanism - has pivoted lever which returns to rest under gravity enabling independent operation
IPC: F41B11/00
Filed: 1980-01-31
Abstract: The device is to enable working of the trigger of a firearm by itself and independently of all other moving parts. It is particularly applicable to a 4.5 calibre air pistol. The arming lever has a small pad by which it may be lifted up by a finger. A notch towards the front serves as a stop for the rest position. Placing in this position is automatic due to the lever weight towards the front returning it without an additional return spring and all its complications. An extension on the lever rear gives pressure on the trigger.

Patent FR-2465550-A1 (FR)
Title: Joining pipes by high energy application - by inserting first pipe into second and expanding first pipe locally by explosion, partic. useful in offshore structures
Inventor: REGALBUTO JOHN ANTHONY
IPC: E02B17/00
Filed: 1980-07-28
Abstract: A method of making a rigid connection between pipes consists of introducing a first pipe into a second then forming a permanent swelling in the first pipe. The swelling is sufficient to bring about a contact between a part of the outer surface of the first pipe and the inner surface of the second pipe, forming a practically rigid connection between the pipes. It is produced by practically instantaneous radial expansion of the first pipe. The method is intended to be used in marine structures for exploration and exploitation of oil-bearing strata. It is less costly than existing methods, and is of simple and economic construction and easy to operate. It does not produce any plastic deformation of the two components of the joint which could alter the properties of the metal, does not give rise to conc. stresses and facilitates precise mathematical prediction of the resistance to fatigue of the joint under a long term cyclical load. The appts. can be easily withdrawn from the components of the joint in case of defective operation. It does not necessitate the use of a supporting anvil block on the outer surface of the outer component to prevent plastic deformation during formation of the joint.

Title: IC engine choke operation warning circuit - has thermistor in temp. gauge to close switch and flash warning light when engine warms up
Inventor: SCHARF THOMAS FREDERICK
IPC: F02B77/08
Filed: 1980-08-18
Abstract: A choke operation warning light (1) is switched on or caused to flash when a switch (6) is in a closed state due to choke operation and the engine temperature reaches a predetermined value as determined by a thermistor (5) of the temperature gauge (4). The light may also be operated with the choke inoperative when the engine temperature becomes excessive. The light may form part of a multi-light warning system for a number of vehicle conditions. The system can also include an engine over-temp. warning circuit that is operative when the choke is not in use. This circuit includes the temp. sensor and indicator light of the choke monitoring circuit.

Title: Heat recovery for IC engine - has fluid for rankine cycle vapour motor heated by exhaust gases
Inventor: RIBAULT JEAN-PAUL RENE
IPC: F02G5/04
Filed: 1980-08-26
Abstract: The energy recovery circuit extracts heat from an I.C engine as mechanical energy and uses a fluid circuit with a Rankine cycle. The fluid is condensed to a liquid and vaporised under pressure in a vessel. The vessel is heated by the exhaust gases of the engine to drive a vapour motor. The heat extracted from cooling of the engine reheats the liquid before introduction into the heater. The surfaces of the engine are maintained at a temperature greater than 150 degrees C. The lubricating oil from the engine can also reheat the liquid before introduction into the heater.

Title: Frame for racing bicycle - has seat tube split at lower end with spaced connections to crank bracket
Inventor: RAKOVER JEAN-JACQUES
IPC: B62K19/00
Filed: 1981-01-13
Abstract: The bicycle frame has a seat support tube of oval cross-section (1a) at its upper section. It extends down to the crank support via two tubes (1b) which also have an oval cross-section.

Patent FR-2474950-A1 (FR)
Inventor: DERIAZ ANDRE
IPC: B31D3/00
Filed: 1981-02-05
Abstract: A pile (5) of alternately arranged corrugated and flat sheets (2, 3) is produced and subsequently immersed in a synthetic resin bath, in order to impregnate the exposed surfaces of the sheets (2, 3) with synthetic resin. Thereafter, the pile (5) is removed from the bath and exposed to conditions which permit curing of the resin by drying or polymerisation. The resin collects in the contact zones between neighbouring flat sheets (3) and corrugated sheets (2) and forms connecting bridges (9) between these sheets (2, 3). This process allows the cost-saving production of a cellular structure having mechanical and physical properties which are at least equivalent to those of a "honeycomb structure" with the conventional hexagonal cells.
