Abstract: 107,965. Blanchereau, R. N. June 29, 1916, [Convention date] Spray carburettors. -The area of the passage around the fuel nozzle is varied by a suction-actuated tubular member H which carries an independently adjustable valve L. The valve is adjusted to obtain a particular proportion of fuel to air, which proportion is then maintained constant throughout the whole range of suction. The member H is coned at its lower end to fit a conical cap G on the nozzle C and thus prevents the passage of gases in the event of a back-fire. The lift of the member is regulated by an adjustable screwed sleeve K, slots in the lower end of which receive the upper bridge-portion of the member. The valve L is adjusted by a milled cap P, slotted sleeve Q, and projections R

Abstract: 575,128. Coating metals. METALLIZING ENGINEERING CO., Inc. June 4, 1943, No. 8984.. Convention date, Aug. 6, 1942. [Class 82 (ii)] [Also in Group XXII] In order to bond a layer of sprayed metal on a metal surface, a series of small amounts of a bonding metal are deposited from at least one electrode which is contacted with the surface electrically connected to it so that the electrode metal is fused to produce on the metal surface an irregularly pitted deposit having its surface characterised by an irregular roughness with a multitude of projections with overhanging edges and minute craters with overhanging edges, coating metal being afterwards sprayed on the conditioned surface. Additional amounts of metal may be deposited on the surface by repeating the bonding operation which may be performed by relative movement between the electrode and the surface. Successive areas of the surface may be coated by contacting the electrode repetitously, e.g. by stroking the surface with the electrode. The coating may be effected in an inert atmosphere, e.g. by clamping the electrode in a holder provided with one or more jets directing an inert gas, such as nitrogen, to the top of the electrode. The coating metal may be steel, copper, bronze, zinc, nickel, aluminium, brass, cast iron or stainless steel and the voltage used may be ¢ to 20 volts.

[Also in Division H2] In an electrically driven toothbrush, having an oscillable shaft 11 passing through a flexible watertight sleeve 31, the motor switch is sealed in an annular compartment by an annular plastic plug 58 and is operable by a pin 42 slidably arranged in a passage 43 which is so narrow that, even when flooded with conductive liquid (on a sudden breakdown of the watertightness of sleeve 31), it provides a conductive path of such high resistance that the leak current from the mains voltage is harmless to the user of the brush. Two unequally deep depressions in ring 48 co-operated with the rounded head of pin 42 to provide on off position for the switch contact 44 engaging the lower end of the pin. On moving ring 48 by a press-button, the pin head is constrained to move out of one depression and into the other, while the pin 42 moves longitudinally to make or break the switch contacts and deforms flexible resilient washer 59.

Abstract: 1,024,931. Rolling. UNITED ENGINEERING & FOUNDRY CO. March 8, 1963 [March 9, 1962], No. 9113/62. Heading B3M. A rolling mill includes a carriage, arranged to support the existing or replacement rolls for the mill, and to be supported by a roller table adjacent the mill for handling workpieces. In operation, a carriage 62 is lifted by a crane on to motor driven rollers 46 in front of an edging mill 9 having vertical rolls 15 and 16 (Fig. 1, not shown). Lateral guides 48 and 49, driven by rack and pinion mechanisms 52 and 54, guide the carriage into position, and laterally extending arms on the carriage allow location of the carriage against the roll housing. The rolls, which are normally driven from a single motor through bevel and spur gears and splined shafts 30, are uncoupled by raising the shafts 30, pressure applied to a portion cylinder assembly in the shafts 30 effecting this lifting. Latches 28 are rotated to keep the couplings lifted, the adjusting screws 36 of the rolls are uncoupled and the rolls are pushed by piston cylinder assemblies 42 along previously aligned rails 31. Arms 35 on the roll chocks engage a rod 61 on a previously lowered rod 58 and the rolls are lifted by a piston cylinder assembly 55. The carriage is driven by the rollers 46 into position beneath the rolls and the rolls are lowered into the base of the carriage, co-operating grooves 33 and 66 on the chocks and carriage locating the rolls in the upright position. The carriage is then moved away from the mill and lifted clear by the hook of a crane engaging between links 69. The housing 13 and 14 of the vertical rolls are hingedly attached at 12 to the housing of a slabbing mill 10. Retraction of the rolls is by means of piston 41. The carriage 62 is provided with trunnions 72 so that when the carriage is placed on a support housed in an appropriate pit (Fig. 8, not shown) the whole carriage can be rotated to bring the rolls into a horizontal position.

[Class 40 (v)] In an overlapping-beam glide-path system according to the parent Specification in which the two overlapping beams are radiated on long and short waves respectively, provision is made for the simultaneous transmission of speech on the long wave channel. The glide path system may be combined with an azimuth course indicating system, the course being defined by two overlapping beams of 30 Mc/s. radiation modulated at 500 c/s. and keyed in complementary rythm. The radiation along the equi-signal course line of this system constitutes one of the overlapping beams of the glide path system, the other being provided by a 300 kc/s. radiation modulated by 50 c/s. indicator signals and by speech signals. The shape of the glide path is adjusted by controlling the amplitude of the 50 c/s. modulating signal from a monitor station. In the aircraft receiver shown in the Figure, the two R.F. frequency bands are amplified in HFA, the tuned circuits of which comprise two band-pass circuits in series, and the 30 Mc/s. signals are separated by the filter F2 and demodulated at D2, the resulting 500 c/s. being applied to a discriminator d and course indicator AI. The 300 kc/s. signals are separated by the filter F1 and demodulated at D1, the resultant speech signals being separated by the filter F3 and applied to the head-set HR, and the 50 c/s. signals being separated by the filter F4. The 50 c/s. and 500 c/s. signals are rectified at C1 and C2 and applied to the two windings of the glide path indicator,
