Title: Improvements in or relating to apparatus for continuous calibration of machining operations by machine tools
IPC: B24B49/04
Filed: 1956-01-26
Abstract: 786,696. Linear dimension gauges. REGIE NATIONALE DES USINES RENAULT. Jan. 26, 1956 [March 2, 1955], No. 2612/56. Class 106 (2). In gauging a machining operation on a workpiece of which the cross-section has projections, e.g. in grinding the hollows of a splined shaft 4, Fig. 1, wherein the work-table 1 undergoes longitudinal displacement under the grinding wheel 8, the calipers are held in a support 11 which may slide longitudinally relative to the machine frame, the movement being limited by an abutment 21 on the frame, and an elastic connection, e.g. the spring 22, is provided with the support 11 and the table 1 so that at the end of each reciprocating movement of the table the support 11 is moved clear of the workpiece to allow a rotary movement of the workpiece about its axis. Preferably the support 11 is clamped by a member 12 to a bar 16 sliding in blocks 17, 18 fast to the table 1, a second bar 13 mounted between the upper ends 14, 15 of the blocks 17, 18 being provided to guide the member 12. In the position shown the support 11 is clear of the workpiece 4 and, on movement of the table and workpiece to the right the spring 22 remains fully extended until the end 20 of the bar 16 abuts the stop 21 on the frame. Continuing movement to the right causes the calipers to move into gauging position in one of the hollows of the workpiece 4 the spring 22 being gradually compressed between the now fixed member 12 and the still moving block 14. During movement in this direction the whole length of the hollow is gauged. On the return stroke of the table 1 the gauging is repeated, the spring 22 holds the bar 16 against the stop 21 until the calipers are once again clear of the workpiece 4 whereat the spring is fully extended and the bar 16 follows the movement of the table to its extreme left position by engagement of the block 17 with a head 19 on the bar. In another embodiment the member 12 can slide freely on the bar 16, a different arrangement of stops and driving connections being provided to achieve the same object. The gauging-head comprises a plate 35, Fig. 4, attached to a head 34 mounted on an arm 33 secured by a split lug 32 to the member 12, the plate 35 carrying a parallelogram spring arrangement 26, 27 to the outer extremities 38, 39 of which the caliper support 11 is attached. The support 11 comprises a part 42, Fig. 7, and a portion 43, the part 42 carrying the fixed feeler 9 and the part 43 carrying the movable feeler 10 which is attached to the upper end of a lever 44 fast with a spring 45 and whose lower end carries a feeler 46 bearing against the end 56 of a pneumatic amplifier 48 of known type. Other forms of movement magnifying apparatus may be employed.

Title: Improvements in or relating to fluoration
IPC: C01G30/00
Filed: 1932-01-29
Abstract: Halogen derivatives of aliphatic hydrocarbons are fluorated by treatment with antimony trifluorodichloride.  For example, on heating together equimolecular proportions of hexachlorethane and antimony trifluorodichloride, two, three, or four chlorine atoms of the hexachlorethane are substituted by fluorine atoms.  To obtain a preferred fluorated compound, diphlegmation and control of the reaction products may be employed.  The reaction velocity may be governed by the rate of delivery of one of the reactants into the reaction chamber.ALSO:Antimony trifluorodichloride is prepared by interacting chlorine with antimony trifluoride.  The reaction may take place in a metal vessel, e.g. a revolving ball-mill, and at a temperature preferably above 70 DEG  C.  The product may be employed as a fluorating agent for halogen derivatives of aliphatic hydrocarbons, with the additional production, for example, of antimony pentachloride.  Thus, on heating together equimolecular proportions of hexachlorethane and antimony trifluorodichloride, two, three or four chlorine atoms of the hexachlorethane are substituted by fluorine atoms.  To obtain a preferred fluorated compound, dephlegmation and control of the reaction products may be employed. The reaction velocity may be governed by the rate of delivery of one of the reactants into the reaction chamber.

Title: Improvements in and relating to circuits for wireless receiving apparatus
IPC: H03G5/26
Filed: 1936-01-30
Abstract: 468,796. Valve circuits for wireless reception. MILNES RADIO CO., Ltd., and MILNES, H. R. Jan. 30, 1936, No. 2793. [Class 40 (v)] Automatic volume and selectivity control is obtained by using normal A.V.C. potentials to control the amount of reaction in H.F. amplifying stages. The D.C. potential developed across the rectifier V2 is applied via the decoupling R2, C2 to the grid of valve VI, preferably of the variable-mu pentode type. Variation of the mutual conductance of V1 by this potential controls the feed-back applied to coil L3 from coil L2, connected to condenser C1 and the second grid of the pentode, in such a manner that an increase in bias due to increase in signal results in a decrease in selectivity and sensitivity.

Title: Improvements in and relating to dry gas meters
Inventor: BIRKS FALCONER MOFFAT
IPC: G01F3/22
Filed: 1954-02-02
Abstract: 802,664. Gas meters. GAS COUNCIL. Feb. 1, 1955 [Feb. 2, 1954; June 30, 1954; Oct. 6, 1954], Nos. 3138/54, 19249/54 and 28825/54. Class 54. A dry gas meter comprises at least three measuring chambers 17, 18, 19, Fig. 4, arranged around a space in a chamber and enclosed on their insides by similar diaphragms 25, 26 and 27, each formed of a stiffened central portion and a surrounding flexible annular portion 35, a valve mechanism 93 for controlling the flow of gas into and out of the measuring chambers, a centrally disposed shaft 56, Fig. 1, for driving the valve mechanism 93 and a crank mechanism 59 for connecting the stiffened portions of the diaphragms to the shaft, the total swept volume of each diaphragm swept by the portion 35 being not greater than 30 per cent. The gas flows from a pipe 12 into a compartment 10 of the meter from which it is allowed to pass to each measuring chamber in turn by the valve mechanism. The latter, through an eccentric pin 101 and a crank 102, drives the indicator of the meter. The flow of measured gas from the chambers is also controlled by the valve 93 and passes through an aperture in a division plate 15 to the outlet pipe 13. Each diaphragm is connected with the crank mechanism 59 by a vertically pivoted link 55 and is prevented from rotating about a vertical axis during its to-andfro movement by a horizontally-pivoted link 42. In a modified construction two horizontally-pivoted links 211 and 212, Fig. 10, are used and are so connected to the diaphragm 224 that the latter is constrained to move on a horizontal axis. A shaft 56 journalled in the bearing 69 and axially located by a stop bush 71 is connected by a bar 97 to lugs 95, 96 to cause the valve mechanism 93 to rotate. Four ports in the valve mechanism are connected by ducts, such as those shown at 80 and 82, with the measuring chambers. Instead of the rotary valve, a pair of reciprocating valves or oscillating valves may be employed and the meter construction may be such that the inlet gas is confined to the upper part of the casing 10, a stuffing-box being provided for the shaft 56, or is allowed to occupy both upper and lower parts 10 and 11 of the casing. In the latter case the valve mechanism directs the gas from the space 11 to each of the measuring compartments in turn. In the constructions described, the centre of gravity of each diaphragm and its connecting rod lies in a vertical plane passing through the axis of the horizontal pins carried by the diaphragm so that the latter has no tendency to turn about that axis. Each diaphragm may have a stroke from “ to # the diameter of a circle of area equal to that of the stiffened portion of the diaphragm while guides 36, 37 for the flexible portion 35 have a radius from “ to <1>/3 of the stroke and may be integral with clamping or stiffening members for the diaphragm. Specification 802,665 is referred to.

Filed: 1922-02-06
Abstract: 175,616. Stõhle, G. Feb. 19, 1921, [Convention date]. Milling helical surfaces.-In a machine for grooving twist drills &c., the flutes are milled by cutters carried by eccentrically-mounted spindles which are controlled to vary the depth of the grooves by a former actuated bv the blankfeeding mechanism, while the edges of the grooves are finished by independently driven clearance cutters. Supporting frames 2, 3, 4, Fig. 1, are secured, the latter adjustably, to a main frame 1 and the frame 2 carries a member 5 adjustably secured in inclined guides, Fig. 2, and provided with a holder 13 in which are mounted sleeves 17 carrying the spindles of clearance cutters 19 and clamped by a screw 21. The main cutters 23 are carried in eccentric bearings in sleeves 25, Fig. 3, mounted on vertically adjustable spindles 31, and are driven from pulleys 29. The depth of the grooves is automatically controlled during the advance of the blank by means of an inclined plane 10 having adjustable abutments 38, 39 and carrying a sliding block 41 engaging an arm 46 secured to the cutter-spindle sleeve. The inclined plane is traversed from a lost-motion slot 37 in the blank-holder by a pin 36, thus raising and lowerthe sleeve 50, the operation of the clamping- members being effected by axial movement of a sleeve 84 having threaded engagement with the sleeve 50. Specifications 125,713 and 156,758 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also a blank feeding mechanism. Near the end of its backward movement the sleeve 84 passes into an adjustable screwed bush 89, Fig. 2 (Cancelled), mounted in a rocker 92 having limited angular movement. Clutch teeth 90 are thus engaged by clutch teeth 91 on the bush to arrest the rotation of the sleeve 84 while the wheel 57 continues its backward movement to rotate the member 50 and unclamp the finished work piece. The wheel 57 is finally arrested by a brake pad 79. A piston 110 carrying a pin 109 is engaged by a trip 112 during the backward movement thus allowing one of the blanks to pass from the magazine into the rocker 92, Fig. 7 (Cancelled). At the end of the movement the trip 112 is disengaged from the piston by a cam ring 114 and the whole series of blanks within the sleeve 84 are moved forward by a hydraulically-checked spring 116. The pinion 58 is then reengaged with its wheel by means of a hand lever 77 to start a fresh operation. During the first part of this movement the holder 50 is rotated relatively to the sleeve 84 to clamp the new blank in position, the strength of the clamping being adjustable by means of a spring 98 controlling the reverse movement of the rocker. This subject-matter does not appear in the Specification as accepted.
