Title: Improvements in or relating to dressing mechanism for grinding or abrasive surfaces
IPC: B24B53/053
Filed: 1924-01-08
Abstract: 221,177. Gleason Works, (Assignees of Slade, A. P., and Bullock, E. W.). Aug. 27, 1923, [Convention date]. Trueing rotating tools; disc, wheel, and roller apparatus.-Mechanism for dressing grinding and abrasive surfaces comprises carborundum or like dressing-tools, which have spherical working surfaces and which are moved about two axes to effect a constant change of position of the curved dressing-surface with reference to the grinder undergoing dressing, whereby the dressing surface maintains the same contour independently of wear. As applied to the dressing of an annular mill type of grinder, three tools are employed, two of which, 44, act respectively upon the faces x<1>, x<2> of the grinder, the third, 25, acting upon the edge of the grinder. The tools 44 are mounted respectively upon slides 5, 6 which are reciprocated within housings 3, through rack and pinion gearing 7 - - 12, Fig. 4, by a shaft 13 which is oscillated about its axis at regular intervals. The tools 44 are each mounted to rotate on bearings 43, Fig. 5, carried by a holder 41, which is rotatably mounted, on an axis perpendicular to that of the tool, in a support 40, carried by the slide, and the holder is oscillated', during reciprocation of the slide, by the engagement of a friction sleeve 45, secured to the holder, with a rod 46, Fig. 2, held against a fixed stop 47 by a spring 48. The tool is rotated by its contact with the grinder, and owing to the oscillation about the axis of the holder, perodicallv reverses its direction of rotation. The tool 25, Fig. 3, is mounted to rotate on bearings 23 in a holder 27, which is oscillated about its axis within a housing 28, through a spring 30 driven by an arbor 15. The arbor is oscillated, through gearing 13, 17, 19, 20 and' a gear sector 22 on a sleeve 21 carrying the gear 20, by the rack 11. The housing 28 is slidable within, and is rotated with the sleeve 21, and is pressed by a spring 31 to press the tool 25 against the grinder.

Title: Measuring device
IPC: B23Q15/02
Filed: 1959-01-07
Abstract: 869,164. Electric control systems. CINCINNATI MILLING MACHINE CO. Jan. 7, 1959 [June 13, 1958], No. 613/59. Class 40 (1). [Also in Group XXIII] To indicate the position of an element attached to the armature of a differential transformer the output of the transformer is " backed off " by a further voltage so that the combined output is zero when the armature is in an offcentre position. As shown (Fig. 1), oscillator 15 feeds the primary 30 of the differential transformer and the primary 18 of a further transformer. When the armature is positioned at 35b for example in accordance with the size of a workpiece its combined output is balanced by that from a tapped part of the secondary of transformer 18 so that the input to an amplifier 39 is zero. This zero input is detected by a phase-sensitive detector 44 also fed with a reference signal from oscillator 15 and used to change over a polarized relay 51. If the armature moves to the second position 35a a different voltage derived from a further tap on the secondary of transformer 18 is balanced by the output of the differential transformer and operates a second relay 151 through amplifier 137 and a sensitive detector 144. Control of grinding of workpiece [Fig. 7).- The armature of the differential transformer 30 is adjusted by the surface of a workpiece held between centres for grinding by wheel 124. The transformer itself is mounted on the grinding wheel guard. During normal feed of the machine solenoid 100 is energized holding valve 101 as shown. Pressure from pump 102 passes through the valve to drive motor 103 and holds gears 106, 107 in engagement. Thus the motor advances the grinding head. When the head reaches a first position polarized relay 51 changes over its contact to energize relay 126. The pressure to a valve 118 is cut-off so that the discharge from the motor through valve 121 is partly blocked. The motor then slows. Grinding continues until relay 151 operates when relay 128 is energized. Solenoid 100 then de-energizes. Valve 101 is changed over so that pressure is supplied to the other side of shift valve 118 so that gears 113, 114 engage reversing the direction of feed on the grinding wheel. Indicating tolerance limits (Fig. 9).-When the workpiece is above maximum size the contacts of relays 51, 151 are as shown, lighting lamp 132; when it is below the minimum they are both in the lower position lighting lamp 133; when the workpiece is above the maximum and below the minimum relay 55 will have its contacts in the lower position and relay 155 in the upper. The lamp 134 will then light,

Title: Electric alarm circuits
Inventor: JONES FRANK WILLIAM
IPC: A61M16/00
Filed: 1961-01-09
Abstract: 931,639. Transistor switching circuits. WHITE & RICHES Ltd. Jan. 8, 1962 [Jan. 9, 1961], No. 846/61. Class 40 (6). An electric alarm circuit includes a two-state transistor trigger T1, T2; two resistancecapacitance networks R1, C1 and R2, C2; a cyclically-operated change-over switch RL2/1, RL2/2 in a first position connects the junction of R1, C1 to the input of the trigger, and the capacitor C2 to a discharge means R8 and vice versa in a second position; and indicating means L responsive to the state of the trigger circuit; the arrangement being such that a steady D.C. applied to the resistors R1, R2 increases the voltage on the capacitor connected to the trigger input to a value at which, should the change-over switch fail to operate, the trigger circuit changes its state operating the indicating means L. As described, cyclicallyoperated valve of an oxygen breathing apparatus controls, via switch SW1, the relay RL2 which operates the pairs of change-over contacts RL2/1, RL2/2. If, due to a fault, the contacts remain in the position shown for an excessive length of time, capacitor C1 charges via resistor R1 until the potential on the base of transistor T1 is sufficient to switch the trigger circuit to its other state. Relay RL1 then releases, completing the circuit to indicator lamp L. A temperature-sensitive resistor X1 is included to compensate for changes in relay resistance with temperature. The circuit of the Provisional Specification (not shown), relates to a delay circuit having only a single capacitance resistance network connected to the trigger circuit input. Closing a switch allows the capacitor to change until the trigger circuit switches operating the indicator lamp. The relay RL1 is provided with a second contact which then disconnects the capacitor from the trigger input and connects it to a discharge circuit to prepare it for a subsequent operation.

Title: Improvements relating to the arc welding of studs and similar members
Inventor: HEAP HARRY RUPERT
IPC: B23K9/20
Filed: 1954-01-12
Abstract: 757,417. Welding by pressure. CROMPTON PARKINSON, Ltd. Jan. 11, 1955 [Jan. 12, 1954], No. 898/54. Class 83 (4). A method of arc welding a steel or steel alloy stud 1, Fig. 1, to a steel or steel alloy plate 2 includes heating the area of the plate surrounding the weld by means of an exothermic chemical reaction so as to control the rate of cooling of the plate after completion of the weld. In this way, the danger of hardening or embrittlement of the weld metal due to an excessive rate of cooling is avoided. The reaction is produced by a pellet 6 comprising a mixture of aluminium powder and iron oxide formed at a pressure of about eight tons per square inch and preferably strengthened with a coat of cellulose lacquer. When the welding circuit is completed, current flows from the stud 1 to the plate 2 through the pellet 6 and one or more lengths of wire 8 which fuse and strike an arc between the stud and pellet so that the latter is fired. The current is now removed and a layer of combustible insulating material 3, which prevents current from passing directly from the stud 1 to the plate 2, is destroyed by the burning pellet. When the plate 2 has reached its maximum temperature a timer in the welding circuit re-connects the current to the stud 1 which is first retracted to strike an arc and then pressed into contact with the plate to complete the weld. In an alternative arrangement, the insulating material 3 is dispensed with and the pellet 6 is fired by an auxiliary electrode which is automatically retracted to strike a subsidiary arc. In Fig. 3, the pellet is fired by a number of combustible projections 13, of a material such as magnesium, and has a neck 14 to contact the stud 1. To prevent loss of heat, a mild steel cover 15 lined with a refractory 16 such as dolomite and tar may be used. Specification 601,459 is referred to.

Title: Method and device for screwing threaded caps on to containers
IPC: B65B7/28
Filed: 1956-01-11
Abstract: 793,276. Applying screw caps to containers. HOFLIGER, O., and KARG, R., [trading as HOFLIGER & KARG.]. Jan. 11, 1956 [Jan. 12, 1955], No. 959/56. Class 125(2). In apparatus for applying screw caps to containers in which pivoted, continuously rotating grippers are swung in to grip the cap, lowered to apply it and then swung out to release the cap and returned to their initial position, the caps are rotated at the same speed as the grippers before being gripped thereby to eliminate relative peripheral motion during the gripping and thus to avoid cap damage and variations in load on the drive. As shown in Fig. 1, a tube 6, mounted in a support bracket 1, is continuously rotated by a belt 12 and contains a stack of screw-caps 5 which are retained by resilient fingers 43 hooking under the lowest cap. A sleeve 18 is slidably mounted on tube 6 and is rotated through a key 19 by the tube. Depending from it are two brackets 29 each provided with a rotatable shaft 32 fitted with an arm 33 carrying a cap gripper 38 and with a second arm 30 coupled to the armature of a solenoid 35. Sleeve 18 is flanged at 22, 23 and can be raised and lowered by rollers 25 carried on a forked lever 27. In operation, solenoids 35 are energized through slip rings 50 and contacts 49 to cause grippers 38 to grip the lowest cap while extending through slots 41 in tube 6. Lever 27 then lowers sleeve 18 so that grippers 38 withdraw the lowest cap past fingers 43 and apply it to the container. Contacts 49 are then removed from rings 50 by suitable means so that springs 46 retract the grippers whereupon fork 27 lifts the sleeve 18 again. Solenoids 35 are again energized to swing the grippers in to grip the next cap. In a modified form, a cam-operated forked lever first swings the grippers in to grip the cap and then lowers the sleeve 18 to apply the cap to the container. Thereupon, the forked lever first swings the grippers outwards and then raises the sleeve to its original position.
