Title: Position control for lifting tongs - esp. for lifting slabs from stack in soaking pit
Inventor: LINCK LOUIS
IPC: B22D29/04
Filed: 1982-05-14
Abstract: A device for lifting slabs from a stack of slabs in a soaking pit consists of a double-tongs device with self-clamping jaws connected to a bridge or a motor by a lifting cable and opened and closed by a block-and-tackle drive. The position and the height of grip of the device are controlled by an assembly comprising one or more level probes mounted on the lower traverse of the device and consisting of a motor, reduction gearing and a drum connected to a weight by a flexible belt which is wound on the drum. The motor is driven in the direction of raising of the weight and has an absolute angular encoder connected by a transmission chain to the lifting motor of the device. The device is useful for lifting cast slabs from a soaking pit for feeding to a rolling mill. The equipment is simple, robust, resistant to heat and shock, and can be positioned accurately for lifting one or more slabs from a stack.

Patent FR-2522722-A1 (FR)
Inventor: QUANTE HEINRICH
IPC: E21D11/15
Filed: 1983-03-04
Abstract: A lagging mat especially suitable as a backfill mat has double hooks at both ends and in addition, at one of the two longitudinal sides, hooks or double hooks opening in the direction of the roadway side, the latter hooks or double hooks making possible a transverse bracing of the mats. In this arrangement, the double hooks provided at the mat ends are shaped at a distance from one another which approximately corresponds to the constructional centre distance between the roadway arches. Such a lagging mat can be placed as leading lagging via the transverse bracing in order to then also be used at the same time as final lagging without further re-hanging, since the double hooks pointing to the interior of the roadway and adjoining the mat ends are inserted into the roadway arches to be erected, i.e. the channel sections are simply put over the projecting double hooks of both adjacent mats.

Title: Machine for slitting leather, provided with supports, carrying handwheels, having variable angular positions.
Inventor: VICENTINI BATTISTA LUIGI
IPC: C14B1/18
Filed: 1983-03-08
Abstract: The present invention relates to a machine for slitting hides. It comprises two handwheels 18 and 19 intended to drive the blade 16, which are mounted on supports 23 and 28 with a variable angular position, each having its own axis of rotation which is vertical or substantially parallel to the axis along which the head 2 of the machine slides. The angular position gamma of each of these supports 23 and 28 is adjusted by means of a differential-screw mechanism formed from a pair of screws 36 and 38 and from a corresponding pair of hollow screws 37 and 39 of different pitch so that each turn of the screws 36 and 38 corresponds to a variation in the distance S between the hollow screws 37 and 39 equal to the difference in pitch of screws 36 and 38. This adjustment is made by means of operating handwheels 42 which act on the differential-screw mechanism. Application to the leather industry.

Title: Auxiliary artificial heart
IPC: A61M60/468
Filed: 1983-04-15
Abstract: The auxiliary artificial heart is an apparatus intended to allow functioning of a heart suffering from a myocardial insufficiency such that it is incapable of fulfilling its functions, and that the only currently possible alternative is transplanting. It is composed of a pump, a single cavity of variable volume weighing a few hundreds of grams driven by a low electric power, the whole being easily transportable by the receiver. Only one easily performable operation which causes little trauma is necessary, which operation consists in covering the pericardium with a flexible fabric of low elasticity which is biologically acceptable and in joining up the pericardium thus reinforced to the skin. It can allow normal life, and help to cure a long-time myocardial disorder. It can also allow a practically normal life while waiting for a transplant. It can ensure prolonged survival in the case of an irreversible terminal insufficiency.

Title: Appliance for the manual grinding of saw teeth
IPC: B23D63/14
Filed: 1984-01-13
Abstract: The invention relates to an appliance for the manual grinding of saw teeth, especially of circular-saw teeth for the sawing of wood, this appliance being based on the principle of reproduction by copying with a template, the profile of which corresponds to the final shape of the tooth after it has been sharpened. This appliance is characterised in that the grinding wheel is carried by a stage 42 adjustable angularly in relation to an arm 3-31, itself movable in two orthogonal planes, namely horizontal and vertical, this arm being equipped with a feeler interacting with a guide template 18 fastened to the frame 1, the contour of this template corresponding to the ideal profile of a tooth after grinding, the grinding wheel thus following by copying the movement imparted to it as a result of the displacement of the feeler on the guide template 18. This appliance can be used for the grinding of circular wood saws.
