Patent FR-2331036-A1 (FR)
Title: Ultrasonic tomographic scanning appts. - has electron beam storage tube operating in alternate write and erase periods
Inventor: DORY JACQUES
IPC: G01S7/52
Filed: 1975-11-04
Abstract: An ultrasonic tomographic scanner has a transducer which scans a body. Mechanical linkage causes generation of scanning signals which are applied to a write beam deflection coil of an electron beam storage tube. A transceiver derives wider signal bursts from transducer under the control of a bi-stable which also controls alternate write and erase modes of the storage tube write beam. Tube comprises a mosaic target which stores the scanned image elementally. In this way an image comprised of a plurality of elements having varying grey levels dependent upon the intensity of the write beam is derived by scanning with read beam of the target. The read out signal is applied to the beam intensity modulating input of a CRT which is scanned in synchronism with the tube read beam over target.

Title: Brine injecting machine for meat - with hollow needles having dihedral points with cutting edge to distend muscles
IPC: A23B4/28
Filed: 1976-10-08
Abstract: Brine injection machine for meat, e.g. hams, consists of a number of hollow needles fixed to a head having a rapid alternating movement. At least some of the needles have dihedral points with a cutting edge which distends the muscle during its passage. The machine consists of an upper plate moving vertically under the influence of a jack and a second parallel plate, the two being connected by stay-bolts, fitted with springs; the bolts slide through the upper plate. The needles are fixed in the upper plate and slide through the lower plate. The upper plate has a reservoir for the brine under pressure and this passes through an axial channel in the needles. The needles give better penetration in the case of the more solid and compact meats which would have received insufficient brine for satisfactory preservation with the old type. This is very important where the rate of treatment is as high as 200-400 hams per hour.

Title: Static roof ventilator unit - also acts as skylight and automatic outlet in case of fire
IPC: F24F7/02
Filed: 1977-01-17
Abstract: The static ventilator also acts as a skylight and as an automatic outlet in case of fire. It can incorporate a series of infinitely adjustable flaps, actuated by ropes, pulleys, and return springs, varying the cross section of the passage through it, or shutting this off completely. The outer casing can be shaped so as to give additional induced draught by the wind outside, whatever the direction and to reduce direct sunlight. There can be a curved transparent cowl hinging on one edge, freeing the opening in the roof completely under the action of compressed gas rams. Opening is automatic, caused by rupture of a thermal fuse in case of fire or manually controlled from the roof itself or a position inside the building. when the cowl hinges open, the flaps can be arranged to retract automatically.

Title: Gas fired room heater - has imitation solid fuel constructed of expanded cellular structured ceramic material above hollow base with jets in upper surface
Inventor: WASHBOURNE COLIN
IPC: F24C3/00
Filed: 1977-03-09
Abstract: The fire has a rectangular hollow base piece. A gas pipe opens into one side of the base through an aerating jet. The top of the base piece has a number of holes through which the gas air mixture flows at the correct speed to form a stable flame above the top. A structure over the top of the base gives the appearance of solid fuel. It is formed of expanded ceramic with an open cellular structure. This material is arranged in lumps resembling coal or coke but with hollow interiors. The burning fuel rises through the hollow spaces and through the cellular structure and thus brings the whole of the imitation solid fuel to red heat.
