Title: Elastomer bonding material for polybutadiene based propellants - contains phenolic antioxidant to enhance adhesion
Inventor: TAUZIA JEAN-MICHEL
IPC: C06B45/12
Filed: 1975-11-28
Abstract: An elastomer based bonding material, for use with composite propellant blocks contg. a polybutadiene binder, also contains phenolic antioxidant(s) as polubutadiene polymerisation catalyst. The bonding material is partially coated on the propellant block to act as inhibitor or as primary layer between the propellant and inhibitor. It contains an elastomer and opt. a refractory filler and/or endothermic decompsn. filler. The elastomer is esp. polybutadiene, EPDM, or a trisequenced copolymer of styrene with butadiene or isoprene Pref. phenolic antioxidants are tri(nonyl phenyl)phosphite (I), di(t.butyl)p-cresol (II) and pentaerythritol tetra 3-(3,5-di-t.butyl-4-hydroxyphenyl)-propionate (III). Improved mechanical properties are obtd., e.g. shear, traction and peel resistance since the propellant surface is more highly crosslinked than the interior and is chemically bonded to the elastomer of the bonding material.

Title: Neutralisation of individual cylinders of IC engine - using butterfly valves or cam shaft in eccentric housing to close inlet and outlet valves
Inventor: BERTIN JEAN HENRI
IPC: F02D17/02
Filed: 1976-02-13
Abstract: The IC engine is equipped with means to neutralise individual cylinders so that at lower power outputs the remaining cylinders are used to give a higher specific fuel consumption than otherwise obtainable. The simplest method consists of butterfly valves operating on the inlet and exhaust ports to individual cylinders. Alternatively, in the case of overhead cam shaft engines a hydraulically operated arm is used to rotate the cam shaft in an eccentric bearing housing so that the cam follower is no longer in contact and the valves remain closed. For an overhead push rod engine the cam follower is hollowed out and filled with oil in normal running conditions, the oil being released for neutralisation allowing the push rod to slide up and down inside the follower.

Abstract: The helmet has rigid inner and outer shells, between which is a shock-absorbing layer composed of tubular cavities running directly across from one rigid shell to the other, the walls of the cavities being made of a permanently-deformable rigid material. A permanently deformable material absorbs more of the force of a blow than a resistant material. The tubular cavities may form a honeycomb, whose walls may be of thin sheet metal, of plastic, of resin-impregnated cloth or card, or of polyester-resin-impregnated cloth. The rigid shells may be of metal or plastic, and may simply rest on the honeycomb core, or be fastened to it, or be fastened to each other.

Title: Car safety belt installation - in which lap and diagonal belts are not fixed to buckle but beside seat cushion releasably received in frame fixed to car
IPC: B60R22/02
Filed: 1976-05-12
Abstract: A safety belt installation for cars has all the attachment points of the safety belt on the same side of the seat as the door, so that the seat belt can be released as soon as the door opens. Two belt portions are fixed to the bodywork at only two points, one low and one high, and near the door. After passing in front of the body, instead of being buckled to the car floor between the two seats, the two belt portions continue as the seat-cushion so that the wt. of the occupant maintains them in place. The body is held against the back-rest by the upper belt portion and on the seat cushion by the lower belt portion. The seat-cushion is freely received in a frame fixed to the car, so that tilting towards the door disengages the seat-cushion from the frame so releasing the seat occupant.

Title: Metal recovery unit having concentric electrode elements - which provide interleaved anode and cathode elements of mesh construction
IPC: C25C7/00
Filed: 1977-05-09
Abstract: Unit includes a container which houses a first electrode formed of >=1 perforated element. A second electrode within the container is formed of a plurality of spaced apart highly perforated elements. The first electrode forms an anode and the second electrode forms a cathode of large surface area. The electrode elements are disposed parallel to each other to provide a plurality of parallel channels within the container. An inlet is provided in the bottom of the container and liquid flows from the inlet to an outlet at the top of the container via all of the channels in parallel. Process is used for recovery of precious metals from rinse tank solns. The electrode elements are disposed concentrically to provide a compact arrangement having a large cathode surface area. The channels increase the ion diffusion rate by increasing the steaming velocity of the soln. This results in increased cathode efficiency. The cathode elements are sandblasted to provide maximum cathode surface area.

Title: Vibration damping system for high speed rotors - has magnetically and fluid operated dampers for both high and low frequencies (NL 13.12.77)
IPC: F16C27/08
Filed: 1977-06-10
Abstract: The rotor (10) is supported on the vibration damper (11) and held central by the upper vibration damper (12). The upper damper consists of a magnet (13) attached to the rotor (10) and a second magnet (14) elastically attached by the bearing supports (15) to the machine frame. The lower end of the rotor is elastically connected by the thin rod (17) to the hemi-spherical bearing (18) which is, in turn, attached by a flexible membrane (21) to the mass (23). The bearing (18) and mass (23) are enclosed in the housing (22) which is filled with a damping fluid. The upper vibration damper (12) absorbs the low frequency vibrations or rigid body modes. The lower damper (11) absorbs two bands of high frequency or flexural vibrations and so permits a wide range of operating speed.
