Patent FR-2523157-A1 (FR)
Title: Boron-contg. tool steels - produced by rapid solidification process, esp. melt spinning
IPC: C22C45/02
Filed: 1982-03-09
Abstract: The alloy has the general compsn. (by wt) 0.2-1.8 (pref. 0.5-1.6)%C, 0-20 (pref. 0-5)% Cr, 0-20 (pref. 0-6)% V, 0-20 (pref. 0-10)%Mo, 0-30 (pref. 0-20)% W, 0-20 (pref. 0-15)% Co, less than 2% Mn+Si+Ni, balance Fe and impurities, with the addn. of 0.1-1.5 (pref. 0.2-1)%B. The alloy is prepd. by rapid solidification and has a single phase body centred cubic structure. Heat treatment may be carried out to form a uniform dispersion of ultrafine metallic carbides and borides in a fine-grained iron-rich matrix. The alloy is esp. a high speed or lot work tool steel. The boron addn. enhances liq. supercooling and facilitates formation of a chemically homogeneous, metastable crystalline product on rapid solidification. The fine borides, formed on heat treatment, strengthen the alloy and do not dissolve at elevated temps, giving enhanced high temp. strength. Boron addn. also promotes good yield of uniform product from melt spinning which is an economical rapid solidification process. The melt-spun filaments can be readily ground to powder which is an esp. useful form for subsequent consolidation to the transformed (ductile) final product.

Title: Test system for radar antenna with electronic sweep - uses auxiliary transceiver operating with panel of modulatable elements at antenna output
Inventor: SAINT JACQUES
IPC: H01Q3/26
Filed: 1982-04-20
Abstract: The main transmitter receiver (10) operates with an antenna (11) comprising radiating elements (12) provided with an electronic sweep controlled by phase shifters (13). The phase shifters are controlled from a digital computer (15) via a pointer circuit (14). An auxiliary transmitter receiver (20,21) uses the antenna via an electronically switched (23) link (22). This use occurs when the main transmitter-receiver is not using the antenna. The auxiliary system transmits to a modulator panel (26) containing a network of elements which have a modulatable coefficient of transmission or reflection. These elements are controlled by an addressing system (27) connected to the receiver and controlled from the computer. An auxiliary computer (31) and A/D converter (32) with an interface (33) to the main computer enable the measurements to be processed to indicate correct operation of the antenna.

Title: Intermediate cable type moving body displacement determn. device - has cable wound on rotating drum with pulse generator and counter
IPC: G01B5/02
Filed: 1982-05-24
Abstract: The device measures the displacement of a moving body such as a machine tool-holder w.r.t. a fixed reference point through use of a cable acted on by the moving body at the moment of its displacement. The cable (1) is wound on a cylindrical drum (2) which rotates about an axis (3) orthogonal to the cable. The free end of the cable (4) is fixed by an anchoring hook (5) to the moving body. The drum wall has threads (6) so that the cable is wound in regular coils. The drum is mounted on a shaft (8) which turns in square support bearings (9) and has an elastic return mechanism such as a spring (10) which constantly resets the drum to its 'wound-cable' position. A pulse generator (11) translates the angular displacement of the drum into electrical pulses which are transmitted to a counter (12) with electronic light display (13), inverse counting (14) and a zero-reset button (15). In an alternative realisation the device has a greater measuring capacity but is less autonomous.

Patent FR-2511417-A1 (FR)
Inventor: SPIEKER FRIEDRICH
IPC: E04H6/24
Filed: 1982-08-05
Abstract: The storehouse (1) has stalls (3, 4) which are arranged one above the other on either side of a stationary elevator (11) which charges the stalls and is provided with a lifting platform (10). The stalls are designed for stacking a plurality of platforms (6) which are located one next to the other and are occupied in each case by transporting units such as vehicles (9), containers or the like. The platforms (6) are received by the lifting platform (10) and transported and, by a train displacement apparatus arranged thereon, pushed into a stall or - coupled together - drawn out of the stall. This takes place such that, in the case of a stall occupied by at least one platform (6), said platform is always stacked at a first point, i.e. directly beside the elevator shaft (2), with the result that it can be reached by the train displacement apparatus, for automatic coupling thereto or uncoupling therefrom, for horizontal displacement. In a similar manner, platforms (6) stacked one beside the other are automatically coupled to one another or uncoupled from one another.
Patent FR-2511743-A1 (FR)
Inventor: BACHMANN LUDWIG
IPC: F16K1/22
Filed: 1982-08-13
Abstract: The invention relates to a plug-in connection between a shaft and a butterfly disc. The butterfly disc is introduced obliquely into the housing; the shaft is inserted into the butterfly disc and the shaft and the butterfly disc lock together as the disc is aligned into its operational position. A pin which is situated opposite the joint, is mounted in the housing and can be pushed into the butterfly disc secures the butterfly disc in its position and, at the same time, generates a prestress in the joint. The axial fixing of and transmission of the forces between the butterfly disc (1) and the shaft (3) is accomplished by the contact between two oblique surfaces (8, 10) and the snapping in of a projection (9) formed on the butterfly disc (1) into a recess (6) machined into the shaft (3).

Title: Bottle packing and palleting machine
Inventor: HOFFMEYER UWE
IPC: B65G57/30
Filed: 1984-03-28
Abstract: At the discharge end of a bottle making machine is a stepping conveyor for forming batches of bottles.  Each batch is lifted by a gripping frame to a level for transfer to the  frame (21) of the packaging machine.  The batch forms a layer of bottles which is inserted into an open carton or onto a tray.   More than one tray can be superimposed to form a stack, and the  stack is lowered onto a pallet. At the bottom of the frame is a table (16) smaller in area than  that of a tray (37).  Above it is a lifting frame with driving chains (25) so that its sides (33) can be lowered to the table while open, then closed together to fit under a tray and lift it. These sides are formed by angle members, their horizontal flanges supporting the tray when closed.  The filled tray can then be  lifted while another tray is moved into position below it.  The process is repeated until a stack of the required has been formed, and the frame is lowered to the disengaged position.
