Filed: 1924-11-06
Abstract: 224,547. Sperry Gyroscope Co., (Assignees of Sperry, E. A.). Nov. 6, 1923, [Convention date]. Morse and like code signal transmitting arrangements. - Relates to methods for automatically signaling the speed, course and identity call of ships, aircraft &c. with the particular object of avoiding a collision in foggy weather. As applied to a wireless signalling system a rotary cylinder 12, Fig. 1, provided with a series of grooves 40 on which are formed raised contacts 43, Fig. 5, corresponding to Morse signals indicating various points of the compass, is set and controlled through a repeater motor and suitable, gearing from a gyroscopic compass. A second similar element 20 carries in grooves 41 other Morse contacts 43 corresponding to various speeds in knots, and is actuated through differential averaging gearing and a repeater motor 24 from the ship's propellers. A third set of contacts 43 on an element 60, Fig. 5, represents the characteristic call sign of the ship. A reciprocating arm 50, Fig. 5, driven by a crank 52 and link 53 sweeps over the aligned contacts, thereby controlling the emission from a valve oscillator shown in Fig. 4, where the key 85 represents the contacts 43, 50,. Fig. 5, and 90 is a buzzer for interrupting the C. W. emission so that the signals will be heard on a crystal receiver. In order to ensure that the reciprocating contact is not jammed if the contacts 43 are slightly out of alignment, notched members 61, 63, 64 are formed at the top of each of the grooves 40, 41 in the cylinders 12, 20, and the contact 50 is spring mounted on the arm 55, Fig. 5, so as to be capable of slight lateral movement. In addition the carriage 51. is given a slight transverse vibration during its vertical motion by means of a series of grooves or notcJhes formed in the sides of the guideway in which it works. Locking means are also provided to prevent any movement of the elements 12, 20 during the transmission of a signal, any lag being restored through a resilient connection between these elements and their respective driving or repeater motors.

Abstract: 934,478. Sharpening saws; sawing. McCULLOCH CORPORATION. July 13, 1962 [April 2, 1962], No. 27082/62. Classes 60 and 145. An engine-driven chain-saw has means adjacent the engine for sharpening the cutters of the saw-chain during normal engine and sawing use, the sharpening means comprising a grinding wheel 49 mounted adjacent the engine and movable into and out of sharpening contact with the edges of the travelling cutter elements 13, Fig. 1, the wheel 49 being rotatable in sharpening contact in a path normal to the path of the cutters; means, also adjacent the engine, provide for movement of the wheel 49 into sharpening contact with the cutters. The grinding wheel shaft 61 is journalled in a swingable housing 53 longitudinally slidable on a support rod 68 whereby the housing and wheel may be moved by a control member 82 into the sharpening position against the action of a spring 70 which normally holds the wheel in the disengaged position shown in Fig. 1. A disc 62 secured to the rear end of the wheel shaft 61 has an outer rim 66 attached to it by a ring 65 of elastomeric material, the rim 66 providing the grinding wheel driving means. As the housing 53 moves towards the saw-chain the rim 66 engages a raised portion of a drum which is rotatable about an axis parallel with the wheel shaft 61 and is gear-driven from the saw-chain sprocket-shaft 23. Lateral adjustment of the housing 53 to ensure driving engagement with the drum is effected by the manual rotation of an eccentrically-mounted member 72, Fig. 3, which engages the forked lower end of the housing to swing it about the rod 68. The control 82 is operated by a push-in knob 100 and screwed stopping sleeve 91 having a serrated flange 95 engageable by a locking member 97. The serrations may be calibrated so that a predetermined amount of feed may be applied to the wheel 49 when the knob is pressed inwards against springs 101 and 70. The saw-chain has side and centre links 29, 30 connected by pintles 31. Sprocketengaging tangs 32 ride in the groove of the chain bar 12 and fit the spaces between the sprocket teeth 24. Extensions 35 on the links limit vertical movement of the links on the sprocket and provide constant positioning of the chain on the sprocket and the cutter elements during sharpening. To this end the side links have arcuate inner edges 36 which ride on outer sprocket discs 21 of the same radii. The cutters 37 and depth-gauges 38 forming each cutter element have arcuate outer edges concentric with the rotational axis of the sprocket so that each contacts the surface 50 of the grinding wheel 49, at the same distance from the centre of the sprocket the surface 50 being tangential to the arc 48.

[Also in Group XIII] In a method of producing a heat-exchanger tube having a ridged surface (see Group XIII), a tube 1, Fig. 3, of initially uniform section is held between die members 8 and 9 having a minimum internal diameter equal to the external diameter of the tube, and a die-ball 10 is drawn through the tube to expand the latter into grooves 19 in the die. The tube 1 may be circular or lenticular, Fig. 4, in crosssection, and in the latter case the die-ball 12 may be so shaped as to cause a flow of material to form thicker walls at the sections of greatest curvature. An alternative method utilizes die surfaces formed as peripheral recesses in one or more pairs of co-operating rollers, the tube being drawn through the recesses with the dieball held within the tube between the rollers, or else the tube is held stationary and the rollers and die-ball moved together along it. The tube may be worked hot or cold, and longitudinal inner ridges may be formed in the tube by a suitably shaped die-ball. To form helical inner ridges a tube formed with longitudinal inner ridges is twisted, and the external ridges are formed subsequently. Also, from a tube of initially circular cross-section, ridged tubes of other cross-sections, e.g. elliptical, may be formed.

Abstract: 962,652. Hydraulic lifting apparatus. LAMBERT ENGINEERING CO. (GLASGOW) Ltd. Nov. 6, 1961 [Aug. 6, 1960], No. 27354/60. Heading B8B. [Also in Division F2] A load moving member which is driven by an hydraulic motor 1 and acted on by a brake 13 is controlled by a system which ensures that the brake is automatically applied when the load is undriven and released when it is driven. The brake control includes a device 19 in which a spring holds the brake on, and hydraulic pressure acting on a piston against the spring pressure releases it. The hydraulic pressure is supplied from a source 6 which drives the motor 1 and this pressure is automatically fed to the device 19 whenever the motor is pressurized. The pressure line to device 19 includes a shuttle valve 35 (Fig. 4) which, when the line is pressurized, closes a conduit 29 leading to reservoir 4 by way of line 30, Fig. 1, but allows pressure to feed the brake control device 19 through a bore 37 in the valve shuttle 38. When motoractuating pressure is released, the spring of device 19 returns its piston and this feeds the fluid in the device back to valve 35 which opens conduit 29 to drain the fluid to reservoir 4. The complete system of Fig. 1 is for a crane in which hydraulic motors 1, 2 and 3 drive respectively the hoisting, luffing and slewing of a crane and brakes 13, 14 and 15 act on the corresponding driven elements, the separate controls operating independently from a common source of hydraulic power such as a pump 5. Each motor 1, 2 or 3 may be reversible, with the brakes automatically operable in both directions of drive. To achieve this the brake controls are each connected into a loop line 32 which joins the forward and reverse lines 27, 28 to the motor.
