Abstract: 336,725. Goralski, M. Aug. 27, 1929. Driving auxiliary parts.-Cam plates 2, 3 which together make a complete wheel are mounted upon a shaft 1 and hollow shaft 4 respectively. On suitably turning the cams by coupling the shafts to the engine shaft 27 the front axle is first raised and then carried to one side. The shaft 27 is in two parts separated by a clutch member 29, operated by a lever 32. If the lever is moved forward a worm 26 drives a wheel 25 in train with mechanism for rotating the shafts 1, 4. The cam 2, Fig. 6, in normal position overlaps the cam 3, but when the clutch 29 is operated the shaft 1 is rotated carrying with it the cam 2 and raising the front axle. When the cams form a wheel as shown they are rotated together and the front of the car is carried to one side.

Abstract: 599,886. Sighting instruments for aircraft. SQUARE D CO. Oct. 6, 1945, No. 26105. Convention date, March 29, 1944. [Classes 97 (i) and 97 (ii)] In a drift-measuring instrument mounted to partake of the oscillations of an aircraft in which coincidence of an object viewed and a reticle is maintained during roll of the aircraft by imparting to the reticle a transverse movement across the field of view, the reticle takes the form of an image of an illuminated slit 24 in a disc 23 and is superimposed on the field of view of the object in the eyepiece of lens 1 by means of a mirror 28 stabilized in space by a gyroscope 40, a dove prism 29 for rotating the image of the slit, objective lens 31, reflecting prism 32 and semi-transparent mirror 33 interposed in the path of the object viewing system. This latter comprises exploring prism 8, stationary reflecting prism 7 and two telescope systems 4, 5, 6 and 1, 2, 3, inverted with respect to each other. Exploring prism 8, disc 23 and dove prism 29 are so mechanically interconnected as to effect a rotation of the dove prism equal to the rotation of the exploring prism and a rotation of the slit double the rotation of the exploring prism. The relative movement between mirror 28 and slit 24 during roll of the craft produces in the field of view of lens 1 lateral apparent movement to the observer proportional to the cosine of the angle of sight.

Abstract: 399,975. Coke ovens. PAVITT, W. H., 90, Chatfield Road, Bronxville, New York, U.S.A. Sept. 20,1932, No. 26166. Convention date, Oct. 26,1931. [Classes 51 (i) and 51 (ii).] In a vertically-flued coke oven having in each half heating-wall two groups of flues B, B<1> or b, bl connected by a top horizontal flue D or d the regenerator chambers extending longitudinally beneath the ovens are divided into compartments corresponding in number with the flues. As shown in an underfired oven which can be heated alternatively by rich and lean gas each flue is connected to two regenerators in adjacent rows, and each regenerator compartment is connected to two flues, so that half of the regenerators can be used for preheating air and the remainder for lean gas. The compartments are in four groups F, F<1>, f, f<1> corresponding with the flue groups, and the supply connections therefor comprise at each side of the oven a short conduit H leading to the outer group, and a long conduit h for the inner group. The exhaust connections comprise short and long conduits G, g of greater cross section, and the two sets of connections are arranged at two levels as shown. The conduits H, h are formed by removable metal pipes having calibrated discharge orifices H<5> while the conduits G, g are formed in the brickwork, and the passage of the waste gases thereto is controlled by calibrated nozzles G<5>, or, for the outermost compartments by dampers G<6>. Pairs of conduits G, g, H, h are connected to common reversing valves I, K, and the flow to and from these valves may be controlled by apertured discs and dampers I<1> in the inlet and outlet connections respectively. Air is supplied to the regenerators through conduits K<6> leading to the cellar space M<0>, which is made airtight and serves as a reservoir of air under a pressure of, say, 1 inch of water. In this space are the rich gas main P, and two lean gas mains QA, QB and the necessary supply connections and control valves. The gas supply to the individual flues is perferably controlled by calibrated discs in the piping. In a modification, Fig. 9, in which lean gas is supplied to alternate regenerators through the conduit h, separate reversing- valves KB are provided for each of these conduits, and alternate connections K<60> can be put into communication either with the lean gas main QC through the stop valve Q6 and reversing valve Q<5>, or with the space M‹ by the damper K<63>. In a further modification, Figs 11, 12, and 13 (not shown), the conduits H, h lead to separate reversing-valves connected by a common conduit to the space M<0>.

Abstract: 463,117. Cables. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.) Sept. 27, 1935, No. 26762. [Class 36] To reduce cross-talk between the conductors of a star quad due to asymmetry of the insulation of each conductor along its length and more particularly a quad in which the conductors are insulated with solid material such as wood pulp or polymerized styrene, the insulated conductors are individually twisted about their own axes and then twisted together into quad form, the conductors being bound together, while maintaining their relative positions in the quad unaltered, either before, during, or after the twisting of the conductors together. The pitch of the individual twist of the conductors is preferably substantially the same as the pitch of the conductors in the quad. The quad may be formed on a machine comprising a rotary supply unit 10 and a take-up unit 60, between which are located twist control devices 30, 50 and a serving head 40. The supply unit comprises a frame 13'carrying bobbins 15 from which the insulated conductors are drawn by the take-up unit, the conductors passing successively through dies 21, 34, 54, 65 carried by the frame 13, twist control devices 30, 50 and take-up unit 60 respectively. The serving head 40 wraps a binding 90 about the conductors as they pass between the dies 34, 54. The supply unit and take-up unit are rotated in opposite directions to twist the conductors together, the twisting taking place either before, during, or after the application of the binding according as to the speed and direction of rotation of the dies 34, 54. Pins 35, 55 are provided for preventing rotation of the dies 34, 54 when desired. The individual twist of the conductors may be obtained by providing means for rotating the bobbins 15 about an axis at right angles to their own. Alternatively, the conductors may be pretwisted before winding on the bobbins. The frame 13 may carry a bobbin 14 from which is drawn a thread 70 forming a core for the quad.
