Title: Pressure transducer for measuring compressive forces in powders - comprising triaxial electrical windings on a small epoxy resin cube
IPC: G01L1/20
Filed: 1974-02-05
Abstract: Pressure transducer comprises a small cubioal body made of electrically insulating material surrounded by three independent multiturn electrical windings, connected in series to follow each of the three major axes of the cube surface. It may be used for measuring triaxial pressure loads within particulate media such as pharmaceutical or moulding material powders, or pellets, i.e. during pelletisation or during certain metallurgical processes, at 0 - 100 degrees and 0 - 2000 bars. It is a simple, compact assembly which can detect small relative changes in length of the support cube in three independent axes. Sensitivity on the electrical resistance measurement is 10-5/bar, linearity and hysteresis errors are 1%.

Title: Explosion shearing of continuously cast billets - where piston carrying moving shear has outer sleeve used to clamp the billet
IPC: B23D33/08
Filed: 1974-02-22
Abstract: A machine for the impulse cutting (explosion cutting) of continuously-cast billets, has two shear knives with one knife moving towards the other. One knife is mounted on the piston rod of a cylinder, the cavity of the cylinder being in intermittent contact with a combustion chamber, whereas the second knife is mounted on a traverse connected to the cylinder housing. A floating sleeve is located round the piston rod and rests on the outer part of the piston, both the piston and the rod being provided with channels so that when the explosion occurs, pressure is exerted on the base of the sleeve. Both the top of the sleeve and the underside of the bolster are pref. provided with projections which clamp the billet during the explosion and shearing. Used for cutting continuously cast steel billets. By clamping the billet on both sides of the shearing point, no axial motion is imparted to the two cut portions which might disturb the process e.g. by raising the bath level in the mould.

Patent FR-2345264-A1 (FR)
Inventor: KALNIN R K
IPC: B23K1/002
Filed: 1976-03-23
Abstract: What is proposed is a method of assembling nonmagnetic current-conducting components into units along an axis of assembly. The assembly is arranged under the effect of electrodynamic forces formed by the interaction of a primary alternating magnetic field directed along the axis of assembly and a secondary magnetic field. The components to be assembled are placed in the primary magnetic field so that the areas covered by the contours of the currents induced in these components by the magnetic field are located in planes approximately perpendicular to the axis of assembly; and in each adjacent pair of components to be assembled the regions covered by the contours of the induced currents at least partially overlap each other.

Title: Rough surface element for water and gas filtration - which is textured with mineral particles in synthetic resin binder
IPC: B01D46/24
Filed: 1976-04-27
Abstract: A pressure filter is claimed as well as its porous, tubular, strainer element which fits inside the filter casing to leave an annular space between the two, the fluid to be filtered being delivered into the annular space and the filtrate being drawn off from the bore of the tubular element; the exterior surface of the element is given a rough, uneven texture and fluid delivered into the annular space is directed to flow along the exterior surface of the element. Both casing and element are pref. hollow, cylindrical. The rough surface is pref. made up of mineral particles such as sand bound by a synthetic resin such as polyurethane or an epoxy resin, the mineral particles being of at least two different grain sizes. The use of the filter to remove suspended solid particle from a liquid is also claimed, the loss of pressure through the element not exceeding 0.35 kg/cm2 and pref. being as low as 0.070 kg/cm2. High capacity filter for removing solid particles from fluids of low viscosity, partic. water and gas. Device has high capacity with very low pressure loss through filter. Filtrate volume delivered per unit area of filter surface is much higher than in previous, similar filters. All these benefits accrue from the turbulence imparted to the incoming fluid by being directed along the rough surface of the element.

Title: Flow control valve actuator - has piston connected by single rod to valve arm and which pivots and slides in small cylinder
IPC: F16K31/163
Filed: 1976-07-13
Abstract: A small high pressure cylinder (16) is used in which slides a piston (28) connected to the valve control arm (52) by only one rod (30). This rod is rigidly fixed to the piston, so that as the valve arm (52) rotates, the piston must pivot and slide in the cylinder. This motion is allowed by leaving adequate clearance between piston and cylinder and fitting an O-ring seal (38) in a groove around the piston periphery. Similar seals (44, 46) are fitted to seal a sliding plate (42) which moves laterally with the piston rod and seals off the open end of the cylinder. The actuating fluid is admitted via passages (34, 36) in the cylinder head and flange (20).

Title: Agricultural tractor transmission system - has selector rods in hollow shafts engaging pins with pinions
IPC: F16H3/083
Filed: 1976-10-06
Abstract: The tractor transmission system comprises sets of change-speed gears both for the drive to the wheels and to the power take-off. A main input shaft carries a set of pinions transmitting the engine torque, and on opposite sides of this shaft are the driving gears to wheels and power take-off. Each of these latter sets of gears has a set of change-speed pinions turning freely on a gearchange shaft, which has an axial bore accommodating a selector rod extending and retracting fingers radially so as to engage grooves in the pinions. By sliding the selector rod axially into a particular position a finger is caused to engage in a groove in the internal peripheral face of a pinion, thus coupling the pinion to the shaft.
