Title: Load transfer system for two vehicles - has lifting arms mounted in transverse channels, and telescopic bar to lock vehicles together
IPC: B65G63/02
Filed: 1978-06-07
Abstract: A load is transferred between a first and a second vehicle using lifting arms located in sunken channels running crossways to the respective vehicle loading platforms. The loading platforms are divided into a number of loading surfaces. Each arm consists of two parts. The upper arm is able to lift and the lower arm slides in and out by means of a hydraulic ram. The two vehicles are manuovered parallel to each other for load transfer and locked together to prevent tilting by means of a hydraulically operated bar. The bar is formed by two telescopic tubes with rectangular cross section held in guide channels running crossways to the vehicle chassis.

Title: Metallic mesh UHF aerial - uses two circular symmetrical planar active elements to provide enhanced reception and transmission
IPC: H01Q9/28
Filed: 1978-11-13
Abstract: An aerial for transmission and reception of U.H.F. signals comprises two active elements (A, B) formed by two symmetrical planar metal surfaces of circular, oval, regular polygon or cross shape and equal size dia. or diagonal. Each element is formed as a trellis or in stretched wire (E), the elements being connected to coaxial cable (C) and effectively from an in phase tuned aerial. The optimum dia. or diagonal lies in the range 0.24 lambda to 0.35 lambda with 0.2 lambda spacing between the elements (A, B) giving an assembly 0.50 lambda to 0.74 lambda. The best performance is obtained with circular elements (A, B) of 0.65 lambda diameter. The elements may be supported in a non-essential dihedral reflector (D).

Title: TDM switching circuit - has control and buffer memory in which address depends on same contents of memory
IPC: H04Q11/04
Filed: 1978-12-26
Abstract: A TDM switching circuit comprises a number of incoming multiplex routes converted in a super-multiplexer into an incoming super-multiplex route, an outgoing super-multiplex route converted by a super-demultiplexer into a number of outgoing multiplex routes, and a buffer memory whose write input is connected to the incoming super-multiplex route and whose read output is connected to the outgoing super-multiplex route. The words present in the time gaps of the incoming super-multiplex route are written sequentially in the information memory of the buffer memory. The buffer memory is addressable by its content and has a circular memory aassociated with the information memory locations in addition to a fixed address memory addressing the components of the outgoing super-multiplex route, and comparators associated with respective information memory locations and address memory locations. Each comparator compares the arbitrary addresses written in the address memory locations with the fixed address of the component routes of the outgoing super-multiplex route and controls the reading of the word associated with the arbitrary address when identity occurs.

Title: Adjustable yarn feed device for knitting machines - having a metering drum of variable diameter
Inventor: SIMIN S K
IPC: B65H51/22
Filed: 1979-02-21
Abstract: A positive yarn feed device for knitting machines has a metering drum of variable dia. consisting of a flexible sheet held in a cylindrical form by means of circular grooves formed in the facing sides of two end discs into which the edges of the flexible sheet are fitted. The grooves may be either in the form of a series of concentric circles of various dias., or of a single, spiral groove in each disc, with a sepn. of 0.3-0.5 mm. between adjacent turns. A yarns guide comprising a fixed post, parallel to the axis of the metering drum, has an initial part inclined w.r.t. the axis of the drum and second part parallel to the axis to ensure a constant spacing of the yarn windings and a smooth progression down the drum surface. The device allows the yarn delivery speed to be easily altered, increasing machine versatility. It is relatively cheap and simple to construct, and has minimal mass in the rotating parts, giving high reliability and hence consistently high quality of the knitted goods, thus increasing machine productivity.

Title: Centrifugal drier partic. for sugar crystals - has wire gauze trap for droplets entrained in air current around bowl
Inventor: JOURNET GERARD
IPC: B04B7/04
Filed: 1979-05-29
Abstract: Continuous, centrifugal drying is of the type having an upwardly divergent conical bowl which is rotated on a vertical axis inside a casing. The space inside the casing is divided, by a circular wall around the bowl and a base beneath it, into a chamber for receiving liq. and another for receiving drained prod. Coaxial annular skirt is fixed externally to the top of the bowl, inside the wall. The skirt extends down so that its bottom edge just projects through a narrow annular slot in an annular, horizontal flange fitted inside the wall. Annular space enclosed by the wall, skirt and flange now contains a pod of wire mesh to trap droplets entrained in the air current passing through the space. Trapped liq. flows by gravity into the liq. reception chamber. Rubber sealing is pref. fitted between the top edge of the wall and bowl. Used in centrifugal drying of a prod., esp. sugar crystals in refineries. Improved efficiency is obtd. partic. elimination of leaks, even when the drained liq. is of low viscosity.

Title: Thermal overload protection relay - uses bimetallic strip across AC line while starting resistors are in circuit to protect them against overheating
Inventor: BAURAND GILLES
IPC: H02H6/00
Filed: 1979-05-21
Abstract: A bi-metallic strip thermal overload relay is suited to the protection of the starting resistances of induction motors which undergo frequent starting and has its operating temperature adjustable by varying the current in the bimetallic strip (26). This is achieved by setting, via external terminals (35,36), parallel paths comprising resistors (31) or diodes across the fixed series dropping resistor (32) in the supply to the bi-metal. The contact (25) of the thermal relay is in series with the operating coil (6) of a contactor which switches the incoming AC supply (3,4,5). The supply to the thermal relay is connected only while the starting resistances (8,9,10) are in circuit, so protecting against unnecessarily long starting procedures. The thermal inertia of the relay protects against overheating due to excessively frequent starting.

Patent FR-2433988-A1 (FR)
IPC: B21D39/08
Filed: 1979-08-21
Abstract: An installation for flaring tubes by electro-impulsion comprises a bed (1), vertical (2) and horizontal (10) guides, means for power supply to electroexplosive cartridges (3), a generator (5) of current impulses and a control system (17). The means for supplying power to the electroexplosive cartridges (3) represents in itself a multielectrode system, which provides for flaring out a plurality of tubes with a single current impulse. For conveniently adjusting the spark gap between the electrodes (4) these are mounted on hinged protective screens (7) so that they may be angularly displaced and secured. The installation is provided with mechanisms (24), (11), (18) for rotation of a bundle (38) of the tubes, for vertical displacement of the power supply means to the electroexplosive cartridges (3) and for horizontal displacement of the vertical guide (2), those mechanisms comprising pitch setting elements, connected, through the control system (17), to the generator (5) of current impulses. On the signal by the said elements, after a programmed displacement of the power supply means and/or after a rotation of the bundle (38) of tubes, the generator (5) gives a current impulse to the electroexplosive cartridges (3). The presence of the elements, setting the pitch of displacement of the power supply means permits, without complicated readjustments, to flare tubes with their butt-ends assembled in rows, circles and spirals.
