Title: Improvements relating to cylinder grinding tools
IPC: B24B33/08
Filed: 1933-08-12
Abstract: 423,988. Grinding cylinders. AUTOMOTIVE MAINTENANCE MACHINERY CO., 816, West Washington Boulevard, Chicago, U.S.A. Aug. 12, 1933, No. 21926 /34. Convention date, Aug. 20, 1932. Divided out of 423,949. [Class 60] Round holes, enlarging and trueing. -Relates to cylinder grinding tools such as described in Specifications 405,323, 405,617, and 423,949 and comprising substantially radially mounted grinding- elements adapted to be expanded into contact with the cylinder wall and consists of a " universal " drive therefor. As shown in Figs. 2 and 3 a spherical extension 36b of the grinding-frame carries two pins 37 which are engaged by bayonet slots 38a in a collar 38 pivoted by pins 39 at rightangles to the pins 37, to the arms 40a of a yoke 40 connected to a member 41 which receives a driving-stem 43 ; the collar is flattened where it engages the arms 40a so as to provide ridges 38<c> which make it impossible to invert the collar in the yoke. In a modification the arms of the yoke are integral with the member receiving the driving-stem, and in another modification the collar 38 is permanently pivoted to the part 36b, the bayonet joint being between the yoke and driving-stem. In all forms the bayonet joint allows ready detachability, without disturbing the grinding adjustment.

Title: Magnetic gauge circuitry
IPC: G01F23/68
Filed: 1973-05-09
Abstract: 1360370 Measuring liquid level electrically FORD MOTOR CO Ltd 9 May 1973 [22 May 1972] 22076/73 Heading G1N In a magnetic gauge of the type having a plurality of coils 28, 30, 32 and indicating means responsive to current flow in the coils, e.g. for indicating the level of fuel in the tank of a vehicle, an orientation and acceleration responsive switch 18 is provided to interrupt current flow from a source of energy 12 to the gauge. As particularly described, a float mechanism varies the resistance of a resistor 36 as the fuel level changes to vary the current flow in the coils 28, 30, 32 of the gauge. The switch 18 comprises a conductive casing 80 provided with an insulated electrode 84 and a conductive ball 88, e.g. of mercury. Contact is made with the switch via a printed circuit cable 16, 20 folded under the casing as shown in Fig. 4. A spring 82 contacts one conductor 16 on the printed cable and the casing 80, and the electrode 84 contacts the other conductor 20. The casing may be filled with a damping fluid 90, e.g. silicone or oil. Normally, the mercury 88 bridges the electrode 84 and the casing 80. However, when the vehicle undergoes a predetermined acceleration or deceleration, or a predetermined change in orientation, the mercury moves out of contact with electrode 84 to interrupt current flow to the gauge. The gauge preferably retains its reading when current flow is interrupted. As an alternative, a normally open switch can be connected in parallel with the gauge, this switch being closed when it undergoes acceleration, deceleration or orientation changes to shunt current round the gauge.

Abstract: 615,144. Sewing-machines. BATA, NARODNI PODNIK. July 29, 1946, No. 22492. Convention date, Jan. 19, 1943. [Class 112] Work-supports in outsole-sewing machines; channelling. In a double-soling machine in which the feed mechanism includes a device for making an incision in the sole during the return stroke of the feed mechanism the work is held against movement with the feed mechanism during this stroke by the needle or the awl, which member is supported on both sides of the work. The support on the far side of the work from the attachment of the needle or awl is preferably well clear of this member during its stroke, to allow it to bend if necessary during penetration of the work, and is moved into contact with the member before the channelling movement commences. In the arrangement shown, the work 7 is fed towards the left by a presser-foot 3, which has a serrated extension 5 slotted for the passage of the needle 4, and a counter-cam 11; and on the return stroke of these devices a knife 1 carried by the presserfoot continues an incision 6 in the work. In the position in Fig. 2 shown the needle is penetrating the work and the presser-foot and cam 11 are about to release the work' for their return movement. The work-support 8 has a slot 9 providing clearance for the needle 4 and awl 12, and is moved to the left from the position shown to bring the right-hand end of the needle slot against the needle to support it against the drag of the knife 1 on the work, the needle being supported on the other side of the work by its guide 2. If the awl is to hold the work against movement by the knife 1 a special support is provided above the work to move against the awl at the appropriate time.

A fuel cell utilizes a reaction in which a thermally unstable compound is formed with the evolution of electrical energy and is then decomposed by a heat source. The compounds may be of many metals with any halogen other than fluorine but bismuth is preferred. A fuel cell for carrying out the present invention is disclosed in the divided Specification 959,032. The process normally operates by convection but may be embodied in an apparatus with a molten salt electrolyte impregnated in a porous separator and thus will operate in the absence of gravity. An extensive list of elements and compounds is given.

Abstract: 384,707. Connecting-rods. DEHN, F. B., 103, Kingsway, London.-(Hensley,. C. G.; 150, Nassau Street, New York, U.S.A.) Aug. 10, 1931, No. 22621. [Class 122 (i).] The parts 2, 3 of a crank shaft for radial engines are connected by crank arms 4, 5, a hollow pin 10 and a bolt 14. The hub 23 of a connecting-rod 20 is journalled on the pin and is formed with flanges 21, 22, in which all the other connecting-rods, such as 31, are journalled by means of pins 33. A locking ring 36 fits in a continuous circular recess in a bush-piece 28 and holds the pins 33 in place. Each pin has a recess in one end so shaped as to bed against the ring 36. The ring has a recess in its outer edge to enable any pin to be withdrawn on turning the ring so that the recess registers with that pin. The ring may be a split ring 58, Fig. 10, and sprung into a groove in the bush 50. In this case the crank 4 has a shoulder 46 and the crank 5 is split and sprung tightly over the end of the pin 49. The pins 33 are held by means of flanges 52 between the ring and the flange 22 on the hub. In another form the pins 33 are held by a split ring at each end. In a two-piece construction, Fig. 22, a pin 72 integral with a crank 70 is gripped by an arm 76 integral with the shaft 3. The metal is cut at 80 between the pin and the bore of the shaft and at 83. To align the crank arms a key of the form shown in Fig. 24 is used. The tongue 88 is placed in the slot 80 and the parts adjusted until the top 87 of the key registers with a shoulder 75 cut in the lower edge of the pin. In each case the ends of the crank arms remote from the main pin are counterweighted as shown at a, b in Fig. 22.

Abstract: 233,592. Long, E. M. Sept. 29, 1924. Cutting glass.-In a lens cutting machine with a rotarv work-holder and a tool-holder oscillated by a pattern member, the tool-holder and a member engaging the pattern member are respectively carried on opposite ends of a single lever pivoted at a point intermediate its ends. The pattern member has zones of different contour merging into one another. A work-support 7 is moved axially by a lever 15, and is rotated through gearing 11, 12, 14 from a crank handle 10, Fig. 2, which also rotates, through a gear 25, a cam 28, Fig. 7, which at the top zone is. elliptical in shape, at the middle zone is circular, and at the bottom is shaped for drop-eye lenses. A bell-crank 33 moves the cam axially of a shaft 21, the setting of the cam being indicated on a scale 35. Contacting with the cam 28 is a tracker 59 pivoted on a pin 60 to a lever 53 spring-pressed by a plunger 47 and mounted on a fulcrum 56 on a carrier 46 adjustable by a handknob 49, angular movement of the tracker being communicated to the tool by a lever 78. Movement of the hand-knob 49 shifts the fulcrum of the lever and varies the size of the lens cut, which movement of the cam by the lever 33 alters the shape of the lens. The tool 65 is spring- mounted in a, holder carrying a contact roller 75. A presser-foot 94 is mounted on a spring-arm 90.
