Title: Device for assisting automobile wheel fitting - tapered fixture screwed to hub stud supports wheel and assists alignment
IPC: B60B29/00
Filed: 1973-11-22
Abstract: There is a lengthening ferrule (1) which is hollow and tapped, the solid end (3) of the ferrule being tapered. At the base of the taper is a hole into which a pin can be fitted as a tommy bar. When the wheel rim (6) of a wheel (7) has to be mounted on the hub, the attachment is first screwed on to one of the retaining studs. It is then easy to engage one of the holes (8), in the rim, with the tapered end of the fixture. This helps to both hold the weight of the wheel and at the same time, to help line up the other holes with their corresponding studs on the hub.
Patent FR-2282937-A1 (FR)
Title: Cocatalytic system prepn fro reforming or isomerisation processes - contg mixt of metal-impregnated and unimpregnated refractory material
Inventor: CARTER JAMES L
IPC: B01J37/04
Filed: 1974-01-08
Abstract: Catalyst system contg. two or more metals and one or mpre nonmetallic refractory component is improved in that the metals are applied (pref. by impregnation with a soln. and recution of the impregnating cpd.) onto a first nonmetallic refractory component, which is then mixed with the same but not impregnated nometallic component or with a different nonmetallic refractory component. This catalyst system is used in reforming or isomerisation processes, or the like. There is synergistic catalytic effect produced by combined action of metals and acid sites on the surface of the refractory materials, such as silica, alumina, etc. The two cocatalyst, however, exert a negative effect on each other when being in physical contact. This disadvantage is minimized by using the metals in small amts. only and depositing them on a minor part of the refractory component(s), the major part being just admixed (without impregnation).

IPC: B01J31/02
Filed: 1974-02-08
Abstract: Ammonia and aldehydes or ketones are selectively oxidized by hydrogen peroxide to the corresponding azines when they are reacted in the presence of both (a) an amide of a carboxylic acid having a pK greater than about 4.3 and (b) a co-catalyst having the general formula H-X-Y=Z, wherein H is hydrogen, X and Z are each an atom of oxygen or nitrogen and Y is an atom of carbon, nitrogen, arsenic, antimony, phosphorus, sulfur, selenium or tellurium; the atoms of X, Y, and Z carrying other substituents necessary to obey the rules of valence. Preferred co-catalysts include di(alkali metal) hydrogen phosphates, lower dialkyl phosphate esters, bicarbonates and p-toluene sulfonic acid. When 1 DEG  or 2 DEG  amines are also present, hydrazones are also formed along with the azines. Uses of the resultant products include their hydrolysis to hydrazines with recycling of aldehyde or ketone.

Title: Self-sealing Y-section catheter or needle union - has two branches for fluid passage directly in line
IPC: F16K15/04
Filed: 1974-04-22
Abstract: The union is for use with medical and veterinary syringe needles and catheters and has at one of its open ends a female cone, with an automatic valve (14).

Title: Coating substrates with molten metal from a bath - contg dosing and coating rollers, plus a roller removing excess metal
IPC: C23C2/00
Filed: 1974-08-26
Abstract: Device permitting the precise deposition of a coating of molten metal on a substrate, without excess thickness of the coating using a roller (I) rotating in a bath of metal kept molten by controlled heating; the deposit is closely controlled to give an exact but adjustable thickness.

Title: Fault indicator for vehicle trafficator lights - includes comparison transistor circuit comparing measured voltage with reference voltage
Inventor: JEAN-PIERRE
IPC: H05B37/03
Filed: 1975-05-16
Abstract: The fault indicator is used for vehicle trafficator lights (13), which are connected to the supply voltage via a switch (10) with a control system for closing the switch (10) and for opening it periodically, so that the lights (13) are illuminated intermittently.
