Abstract: 258,619. Mirault, A., and Kientzi, G. Sept. 21, 1925, [Convention date]. No Patent granted (Sealing fee not paid). Secret contact combination switches for preventing the theft of motor vehicles comprise a series of lettered drums T, T<1>, T<11>, T<111>, which, when correctly set, close one or more electric circuits, e.g. the ignition circuit and the circuit for the electric starter. In the form shown, each drum carries a pair of contacts 12 connected by a conducting bar 13 and between and at the ends of the drums are arranged fixed discs 6, 5, each carrying eight fixed contacts 9 arranged at equal distances round its periphery, Fig. 3. Only when the drums are in the position shown is a circuit completed between two terminals 10 through the contacts 9, 12.

Title: Chlorinated terpenes
IPC: C07C23/10
Filed: 1951-10-05
Abstract: The invention comprises chlorination products of p-methadienes having a chlorine content of 5-8 chlorine atoms per molecule.  The chlorination may be effected by passing chlorine through the said terpenes, mixtures thereof, essential oils containing a substantial proportion thereof, or solutions thereof in solvents inert to the action of chlorine, in the presence of actinic light. The products possess insecticidal properties.  In examples: (1) chlorine is passed through phellandrene at 60 DEG C. for 3 days, with irradiation by incandescent filament lamps after the first 6 hours; (2) chlorine is passed through a boiling solution of phellandrene in carbon tetrachloride, irradiated with ultra-violet light, for 2 hours; (3) chlorine is passed through a boiling solution of dipentene in carbon tetrachloride, irradiated as in (1), for 24 hours; (4) the concentration of the solution in (3) is increased, additional dipentene being added after 15 hours chlorination, and chlorination then continued for a further 12 hours.ALSO:As insecticides may be employed chlorination products of p-menthadienes having a chlorine content of 5-8 chlorine atoms per molecule.  They may be applied as solutions (e.g. in hydrocarbon solvents), as emulsions, or by dusting in admixture with an inert powdered carrier, or they may constitute the active ingredients in wettable powder preparations.

Filed: 1957-07-30
Abstract: 844,955. Excavators. AVELING-BARFORD Ltd. July 18, 1958 [July 30, 1957], No. 24132/57. Class 68(1). [Also in Groups XXIV and XXX]. In a locking device, particularly for locking the rotatable superstructure of an excavator or crane, wherein a dog 16 is moved, e.g. manually, into and out of engagement with the internal or external teeth of a gear 10, the dog 16 moves in a plane 24 which is parallel to a radial plane 13 and is spaced from it by a distance such that the gear tooth flank exerts only a negligible component of force in the plane 24, i.e. the tendency to disengage under gear torque is negligible. As shown two pairs of dogs 15, 16 and 17, 18 are formed on a sprag 11, Fig. 2, mounted on a shaft whose axis 12 is perpendicular to a radial plane 13 of a gear 10 having flat-sided internal teeth. Bosses 14 prevent axial movement of the sprag. The tangents to the tooth flanks contacted by the dogs 16 and 17 lie in the planes in which the dogs move so that they experience no tendency for disengagement. The tangents (such as 27) to the tooth flanks contacted by the dogs 15 and 18 are inclined slightly to the planes in which the dogs move so that the dogs experience a slight tendency for disengagement. The spacing of the plane 24 from the plane 13 is the product of the pitch circle radius and the sine of the pressure angle P. It is stated that the spacing of the plane of movement of any dog should not differ from this product by more than twice the gear tooth pitch. In a modification, Fig. 3 (not shown), a locking sprag co-operates with a gear having external involute teeth. When applied to a crane or excavator having an undercarriage 45, Fig. 5, on wheels or tracks 46 and a superstructure 43 mounted to rotate on rollers 44, the locking device comprises an internally-toothed gear ring 47 on the undercarriage co-operating with a sprag 11 as shown in Fig. 1, the sprag being rotated about stub shafts 52 by a hand lever 58 linked, preferably adjustably, thereto. The lever 58 is preferably provided with a latch 59 cooperating with a slotted quadrant 60.
