Title: Device for relative orientation of parts - has composite mandrel assembled of separate, independently movable, telescopically joined tubes
Inventor: GUSEV A A
IPC: G04D1/06
Filed: 1974-09-10
Abstract: The device has a composite mandrel assembled of separate independently movable members, such as of telescopically joined tubes. Each tube is spring-loaded in the direction of contact of the mandrel with parts to be oriented. During the successive contact of the composite mandrel with the parts being oriented each part, while cooperating with one of the tubes of the mandrel depending on its diameter, is positioned strictly coaxially with the common axis of the mandrel which represents the axis of orientation of a group of parts. The device is suitable both for the assembly and for oriented feeding of parts of different diameter and shape.

Title: Dry prodn. of non woven fabric from particulate material - deposited by low speed turbulent air flow onto porous surface
Inventor: DESVERCHERE JEAN
IPC: D04H1/54
Filed: 1975-03-11
Abstract: Dry prodn. of a non-woven fabric from particulate material (e.g. fibres) is effected by feeding the particles pref. downwardly through a hood in a low speed turbulent air stream generated pref. by cyclone nozzles at the top of the hood. At the bottom of the hood the fibres are deposited onto a porous surface, pref. a conveyor belt at a volume flow rate of less than 2000 cm3/m2/min. and during the movement downwardly through the hood the turbulence in the air stream produces an upward force on the particles less than the gravitational force. The particles are condensed into a layer on the porous surface by a suction created by a 95% vacuum beneath the porous surface, and the layer of particles is then advanced to a pressing operation. A nonwoven fabric of high uniformity is achieved.
Patent FR-2266375-A1 (FR)
Title: Sync. voltage deriving cct. for rectifiers - has monitoring coil of auxiliary transformer bridged by compensating inductor
IPC: H02M1/08
Filed: 1975-03-24
Abstract: The synchronising circuit obtains a synchronising voltage for an externally commutated static converter control circuit by using a coil wound around the line between the converter auxiliary transformer and the converter itself. This coil is bridged by a compensating inductor connected in series with the secondary of another transformer whose primary is connected across the first transformer secondary. The synchronising voltage is taken from the terminals connected to the series combination of the compensation inductor and the second transformer secondary. The circuit ensures that the synchronising voltage phase is independent of frequency without significantly increasing the overlap time.

Title: Adaptor union for mixer tap plumbing - has laterally offset inlet and outlet pipe axes to compensate for difference in pipe spacing
IPC: F16K11/20
Filed: 1975-07-15
Abstract: The adaptor is for connecting parallel pipes for plumbing-in domestic hot and cold water mixer taps when a difference in lateral spacing between the pairs of connections exists. The adaptor is a junction piece (1,2) in which the axes of the inlet and outlet sides are laterally offset by a small amount. The inlet and outlet sides may be tapped or externally threaded to take standard assembly nuts (7) and unions. One or both junction pieces are rotated relative to the installed pipes and the tap connection fitting, to compensate for the different lateral spacings of input and output. The degree of eccentricity is chosen so that the sum of the offset axis distances of the two adaptors exceeds the difference in spacing between the pipes.

Title: Fixing strips to surface of cylindrical boxes - using suction wheel holding strips with are precut and pre-glued
Inventor: GRANCHER ROBERT EMILE LUCIEN
IPC: B65B51/06
Filed: 1976-04-29
Abstract: The strips (4) have a central wire (8) which is precut, at desired intervals, between a set of two rollers (10, 16) having a circumference equal to the lengths of strip required. The top roller has a knife edge (20) and the bottom roller is provided with a ring (14) rotating around a ball-bearing race (12). The strip is then fed, already glued and glued side to the exterior, onto a suction wheel, provided with orifices around its circumference, which has a diameter equal to a whole number multiplied by the lengths of strip required. V-shaped knife edges on the wheel cut the strip, this strip occurring a few millimetres in front of the cut already made in the wire. The strips are then rolled onto the cylindrica boxes which are pressed against the suction wheel.
Patent FR-2361261-A1 (FR)
Title: Vehicle collision protection system - is used for rail vehicles and employs two sets of transmitters injecting into rails
IPC: B61L3/22
Filed: 1976-08-09
Abstract: Each of several transmitter is connected between the line sections and they produce heterodyne AC voltage signals within given frequency bands. The first lot of transmitters is interposed between the second lot along the line sections. A shunt device in the vehicle has a traction motor receiving electrical energy and the two lots of control signals. These are picked up by taps in the vehicle. A fitter connected to the taps distinguishes between the first and second band pass regions and supplies first and second output signals reproducing the control signal amplitudes. A control device receives the output signals and can thus bring the vehicle to a halt when necessary.

Title: Grading machine blade inclination adjustment - uses piston washers bearing on nut preloaded by Belleville washer (SW 20.6.77)
Inventor: AUGUSTSSON BENGT GUNNE
IPC: E02F3/76
Filed: 1976-11-26
Abstract: The remote controlled hydraulic linkage varies the inclination of a grading machine blade. The machine may be used in Highway Construction. Blade manipulation arms have auto-locked pin joints (M) whereby the blade is fixed at the required angle. The joints are locked by friction grip bolts or axles (1), and hydraulic cells (29) are used to nullify bolt tension, and thus permit blade inclination adjustment. Two lifting jacks, of which the housings are pinned to the free ends of the two radius arms (4) manipulate the blade. The other ends of the radius arms (4) are pinned (M) to diametrically opposed plates (5) on the vehicle chassis (10). A third similar jack-radius arm may be sited between the primary pair. The piston rod of the third jack terminates in a ball joint which slides in a groove in the blade back.

Title: Toy knitting machine - with crank wheel actuating reciprocating and turning needle and plastic frame feed mechanism
IPC: D04B33/00
Filed: 1976-11-30
Abstract: A toy knitting machine to knit yarn in loops around a continuous plastic grid frame consists of a crank handle, a feed mechanism for the frame and a needle which moves up and down and has a hook at the end. By coordinating a reciprocating movement with a twisting movement the yarn can be fixed in loops to the frame. The rotation of a crank on a wheel of the drive shaft turns a contrate wheel and through a gear wheel the disc which has a radial slot. A crosspiece with a pin which engages in this slot has a toothed rack in engagement with a gear wheel. This turns the needle with the hook at a certain point of its up and down stroke. All movements are derived from a simple turning of a crank handle.
