Title: Sea-wall of cellular precast blocks laid in bonded courses - contains heads piles filled with concrete and tied in vertical bars
IPC: E02D29/02
Filed: 1976-10-08
Abstract: The sea-defence or quay-wall is constructed of modular cellular pre-formed blocks (1) which constitute the permanent formwork for a reinforced (3) concrete (6) sub-structure. The blocks are assembled and anchored by e.g. 'H' section piles (4). The reinforcement bars are then inserted and concrete finally poured to obtain a homogenous structure. The blocks (1) may be of a rectangular hollow horizontal section with transverse webs forming four similar vertical ducts, and may be laid in stretcher bonded courses to form a continuous wall barrier. Vertical reinforcing bars (3) pass through web-holes, and the ducts which receive the in situ concrete also receive the projecting heads of steel piles (4). Provision is made for horizontal anchor ties to hook onto the reinforcing bars, and high walls may use blocks of decreasing depth. In the latter case rear-face steps every three courses may effect the block depth transition.

Title: Cylinder lock with curved shank key - has key slidable into curved slot to displace sprung pins
Inventor: AOYAMA TAIZOU
IPC: E05B19/04
Filed: 1977-01-05
Abstract: The cylinder lock has a curved slot (5a) which accepts a correspondingly curved key (13). The key moves sprung pegs (8,11) into the position that will allow the cylinder to turn. Notches can be cut in the key on the side that faces the pegs (8,11), which themselves may be on either or both sides of the key slot. The key has a corner (12) cut off the end to assist in pushing the pegs down. The curved slot hides the tops of the pegs from view from the keyhole, and that this frustrates the usual method of picking a cylinder lock with a wire.

Title: Electromagnetic generation of ultrasonic waves - in specimen undergoing inspection involving reflection of ultrasound involves RF generator
IPC: G01N29/24
Filed: 1977-01-07
Abstract: A system is used for electromagnetic generation of ultrasonic waves in a specimen undergoing inspection involving the detection of reflected ultrasonic waves. A magnet produces a constant magnetic field within the specimen. An emitting coil is connected to a radio frequency generator and mounted near the poles of the magnet thus inducing a radio frequency field in the specimen. A receiving coil is connected to a reciver and mounted near the poles of the magnet. This receives reflected ultrasonic signals from the specimen corresponding to the emitted signal. Two coils are laterally spaced relative to each other. The two coils (8) are mounted near the same pole (1) of the magnet which produces a magnetic field normal to the surface of the speciment (5).
Patent FR-2342491-A1 (FR)
Title: Viscosity of high-polymers measured on roll - by pressure speed and gap distance of auxiliary roll
IPC: G01N11/00
Filed: 1977-02-21
Abstract: The viscosity of high-polymer materials travelling around a roll is measured using a second, measuring roll, the material passing through the roll gap between this and the main roll. The gap pressure, gap distance, and the peripheral speed of one roll and/or the other are determined. From these, the viscosity is calculated. The readings may be determined as electrical signals. Viscosities of a wide range of values can be measured. There is no secondary action in the form of the shear forces, which reduce the viscosity by forcing a rise of temperature.

Title: Pendulum for measuring inertia and centre of gravity - has rotary turntable on knife-edge and adjustable sliding weight
Inventor: MERLET JOSEPH
IPC: G01M1/12
Filed: 1977-03-31
Abstract: The precision pendulum for measuring moments of inertia and centres of gravity consists of a support platform with centring device on which the item under tests rests. The platform can be rotated on roller bearings via a remote-controlled stepping motor. The bearing is supported on a knife-edge bearing onto a cross beam. Arms projecting from the knife-edge assembly support a stabilizing weight. The weight has a vertical extension in the form of a bar which supports a sliding, auxiliary weight whose vertical position on the bar may be adjusted. After rotating the test item to its desired position via the motor, so that the pendulum is balanced, the system is set in oscillation. The period of oscillation of the pendulum is then measured for two different positions of the auxiliary weight.

Title: Detecting vibrations in liq. - by piezoelectric transducer partic. for low frequencies and high temp. e.g. in nuclear reactor coolant constituted by liq. metal
Inventor: BLANC RAYMOND
IPC: B06B1/06
Filed: 1977-05-23
Abstract: A detector of vibrations in a liq. comprises a piezoelectric transducer in a cavity sealed by a membrane in contact with the liq. A vacuum is maintained in the cavity. The membrane is connected to one of the faces of the transducer by a component which transmits vibrations, made of a material which is thermally insulating. The other face of the transducer is fixed and the cavity has a fluid-tight passage for an electric conductor. The detector is partic. adapted for detecting low-frequency vibrations transmitted by a liq. at high temps., e.g. the liq. metal coolant of a nuclear reactor. Satisfactory thermal insulation is achieved through the vacuum established in the cavity and the mechanical transmission component. Low frequency vibrations are detected because of the good electrical insulation and the amplification due to the membrane.

Title: Two level traffic interchange - has low leVel radial entries and high level spiral exits and enhances flow of traffic
IPC: E01C1/04
Filed: 1977-09-13
Abstract: The two level traffic interchange achieves free-flow non-intersecting vehicle stream conditions at two levels instead of three or four levels by using low level radial entries and high level spiral exits. The same side of each radial entry has connections to each spiral exit so that each exit is connected to each entry and the slip roads are arranged in pairs. The use of two instead of three or four levels to provide non-intersecting flows reduces building works such as bridges and retaining walls.

Title: Clamps for locking the traverse of an injection moulding platen - involving radial clamps around the traverse ram or tie bars
IPC: B29C45/67
Filed: 1977-12-14
Abstract: Clamping mechanisms for locking the mobile platen of an injection moulding machine in the closed position comprise use of coaxial hydraulic rams to contract radial wedges against either the body of a traverse ram integral with the mobile platen or against each of the tie bard upon which the platens are carried. The traverse ram passes through a supplementary static platen which supports opposing annular hydraulic rams for engaging convergeant annular sets of wedges. As the grip is released, a spacer ensures that the inner wedges are parted during axial retraction of the outer wedges. The clamps may comprise groups of individual wedges or a hollow conic sleeve of variable dia. because of the meshed pattern of partial longitudinal.
