Title: Plastic crate for bottles in bottle carriers - has star shaped spacers projecting from bottom of crate through holes in bottom of bottle carrier
IPC: B65D1/24
Filed: 1973-10-02
Abstract: a plastic crate for transporting bottles in bottle carriers is divided into compartments each of which is of a size to receive a pack comprising e.g. six filled bottles in a bottle carrier. Star shaped spacers project up from the bottom of each compartment and extend up through corresponding holes in the bottom of the bottle carrier so as to be disposed between the bottles to prevent them from bumping one another during shipment.

Title: Tensioning device for strip winding machine - varies tension proportionally to radius of roll sensed by lever
IPC: B65H23/195
Filed: 1974-02-28
Abstract: The device is based on an oscillating roller, around which the strip passes, mounted on a pivoted arm together with an adjustable counterweight. A pneumatic piston also acts on the pivot arm, controlling the tension of the strip. Air supplied to the piston is varied by a valve operated by a second pivot arm. This is moved by a cam rotated by a third pivot arm, the end of which has a roller running against the roll of material. The cam thus controls the relationship between the strip tension and the roll radius.

Title: Flexible coupling for large pipe line tubes - hydrogen separated by a temperature pressure system from the steam mixture is recirculated to combustion chamber
IPC: F16L27/04
Filed: 1974-04-19
Abstract: When inserting pipe line tubes down drill holes, it is an advantage when the joints between the tube sections are flexible to allow correction of axial alignment. This is achieved by using a coupling ring with a spherical outside diameter. One tube end is provided with a sleeve which has an internal spherical seat for the coupling ring. The end of the other tube which has an external groove fits inside the coupling ring. It is held there by retainer blocks which are inserted radially through slots in the coupling ring. The blocks which are held in position by springs engage the external groove on the tube end thus retaining it in position.

Title: Adhesive bonded battery casing joint - incorporating polyamide adhesives of high fracture energies
IPC: H01M50/105
Filed: 1974-07-31
Abstract: Casing joints for batteries comprising a stack of positive and negative electrodes separated by layers of electrolyte impregnated sheet and cell separation plate in a casing of metal with a plastic lining, where the rims of the casing plates, separator plates and electrolyte frames are bonded into a multiple joint by an adhesive polyamide of viscosity 1-100 poise at 175 degrees C and ratios of tensile strength/elongation to break in kg/cm2 as follows: >=0.21 at 21 degrees C; >=0.14 at 32-43 degrees C; >=0.07 at 52-60 degrees C.

Title: Electronic decoy technique for electromagnetically guided missiles - involves creating fictitious targets using several coherent transmission sources and program calculator
Inventor: MENDELSOHN YVES
IPC: G01S7/38
Filed: 1975-10-13
Abstract: The electronic decoy technique is suitable for use with electromagnetic autopilots on missiles. It consists essentially in creating fictitious targets by means of several coherent transmission sources separated from each other but able to be positioned totally or partially inside the danger zone for the objective being defended. The practical implementation involves setting up two or more decoy stations which are geographically separated. Each station is provided with transmission and reception equipments which operate alternately. The stations are linked with a programming calculator unit which measures the frequencies and relative phases of the radiations received from the missiles at the stations. The frequency, phase, and power necessary are then computed and an appropriate decoy signal is transmitted which creates a fictitious target, shifted azimuthally. The calculator unit may measure also the differential Doppler effect.

Title: Multi-plate corrugated metal pipe for culverts - has slotted holes for inter plate connecting bolts permitting circumferential yield
IPC: F16L9/22
Filed: 1976-06-08
Abstract: The multi-plate corrugated metal pipes for culverts include slotted edge holes (5a) for the inter-plate connecting bolts (6). The slots align normally to the joint and with pipe circumferences (3a) to permit a "yield" type slippage at the joints during service. The slippage is controlled by a specific bolt torque and obviates local plate failure at the bolt holes during certain loading conditions. The constituent plates (1) occupy a fraction of the pipe circumference, have uniform circumferential corrugations (2), and are lap-jointed on lines parallel to the pipe axis to build cylindrical sections. The sections are similarly lap-jointed along circumferential edges (1a). Slippage may occur at tangential loads likely to cause local plate failure, and total slippages of up to 5% of the pipe dia. may be permitted.
