Title: Improvements in or relating to internal diameter measuring apparatus
Inventor: BOOSEY FREDERICK ROBERT
IPC: G01B13/10
Filed: 1959-05-19
Abstract: 885,669. Bore gauges. SIGMA INSTRU-  MENT CO. Ltd. May 4, 1960 [May 19, 1959], No. 16956/59. Class 106 (2). Apparatus for measuring internal diameters of  holes in workpieces comprises a mandrel 1 (Fig.  1) carrying a pair of diametrally opposite balls 4 bearing on a tapered part of a push rod 6 and means (Fig. 2) for indicating displacement of a member 7 movable with the push rod in relation to the end plane X-X of the mandrel. Fig. 1 shows the device being adjusted prior to gauging.  A distance piece 7 is inserted between the push  rod 6 and a button 8 which is clamped against  the end face X-X of the mandrel 1 by a member 9. The balls 4 are placed between the jaws 16, 17 of a known measuring instrument the micrometer 19 of which is adjusted until the pointer 20A reads zero. The reading of the micrometer 19 gives an indication of the setting of the bore gauge under a standard gauging pressure. The device shown in Fig. 2 is used to make the required measurements. A known pneumatic gauge 24 with a measuring plunger 26 is clamped to a plug 34 by a nut 35 so that a second button 33 is held against the end face of the plunger housing 28, and the plunger is urged outwardly by a spring 30. The indicating pointer 24A of the pneumatic head 24 is then set to zero. The member 9 is then unscrewed from the mandrel 1 and the plug 34 removed from the nut 35. The nut 35 is screwed on to the threaded end of the mandrel 1, the buttons 8, 33 being removed, so that the end face of the mandrel abuts the end face of the housing 28 and the distance piece 7 and the plunger 26 are touching one another. Then if the mandrel 1 is inserted into a bore having a diameter equal to that which was set up on the micrometer, the indicator 24A will read zero. Any variation in this reading is a measure of the discrepancy between the hole being checked and the micrometer reading. A series of distance pieces 7 may be provided to enable the apparatus to be used over a wide range of diameters. If desired four balls may be used instead of the two shown. Specification 724,205 is referred to.

Title: Frequency multiplier
IPC: H03B19/10
Filed: 1945-07-03
Abstract: 600,788. Pulse frequency multiplying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 3, 1945, No. 16982. Convention date, Oct. 5, 1943. [Class 40 (vi)] A frequency multiplier consists of two or more trigger circuits with their input electrodes connected in parallel to a source of synchronizing pulses and with a differentiating connection between the output electrode of a stage and the input electrodes of each succeeding stage, whereby the latter are also triggered in the intervals between the primary synchronizing pulses. The Figure shows a frequency doubler in which biassed multivibrators 1, 2 preferably generate symmetrical waveforms at the fundamental and first harmonic frequencies respectively, and are' tripped simultaneously by negative pulses applied over lead 10. Stage 2 reverts to the passive state first and is triggered again by a negative pulse derived from differentiating coupling C2, R3 when stage 1 reverts to its passive state. An output at twice the frequency of synchronization appears at electrode 12 and may be applied to a further stage of multiplication. The parallel connection between the input circuits of successive stages includes a diode such as D2 to prevent negative reacting back through the system. Diodes D1, D3 eliminate the effect of cathode resistors R1, R3 while valves V1, V3 are conducting.

Abstract: 1436128 Testing plastics tubing WIRSBO BRUKS AB 28 March 1974 [10 April 1973]  17215/73 Heading G1S Plastics tubing 10 hot from extrusion apparatus is moved through seals 3, 5 in a heating chamber 1 placed under vacuum by a suction hose 12 and regulating valve 11 so that any break or disconformity in the tube allows air to be drawn from the interior of the tube or along the outer surface into the vacuum chamber, thereby causing an increase in pressure which is shown on a meter 4. Major changes or ballooning of the tube due to pressure differential indicate for example either a substantial reduction in wall thickness permitting ballooning to occur, or a reduction in cross-linking forces thus permitting ballooning to occur by virtue of the more thermoplastic nature of the material. These effects may be enhanced by supplying gas under pressure to the inside of the tube. A second inlet 23 comprises a pressure switch 8 connected to an electric alarm circuit or relay (not shown). Automatic marking or indicating means may be provided to indicate the area of the fault.

Abstract: 405,869. Type - bar - making machines. INTERTYPE CORPORATION, 360, Furman Street, Brooklyn, New York, U.S.A. June 19, 1933, No. 17419. Convention date, July 1, 1932. [Class 100 (iii).] Clamping matrices.-In a type-line casting- machine having a device for automatically moving a vice jaw from the position at which it is set to receive a line to close against a short matrix line, thereby covering the front of the remaining mould length, there is provided a stop adjustable by hand which, independently of the usual line-measure stops, serves to limit the backward movement of the jaw during justification to any predetermined point. The vice jaw a is moved up against a short matrix line by a lever d through the link c and rod b, the locking pawl g for the jaw having been released by the downward motion of the first elevator f. A stop h shaped to fit a recess i in the vice jaw is jointed to a rack which can be moved backwards or forwards by a spur wheel m rotated by a knob l. The stop h is maintained out of engagement with the recess i by a spring n until the elevator f is lowered, when a resilient pin o thereon engages the stop h and presses it down into the path of the recess i, so that, when the vice-jaw is moved back during justification, its movement is limited by the stop, and short type parts on longer slugs are justified to exactly the same length at the right-hand end. The stop h and rack k are locked in adjusted position by a pawl which is carried by the knob l and is pressed into engagement with a further set of teeth on the rack by a spring. To adjust the stop h, the knob l is pulled out to disengage the locking pawl from its rack and is then rotated, the stop being re-locked in position by pressing the knob in. A scale may be provided on the knob, on the rack k, or on the stop h to facilitate adjustment. After the casting of the line, the elevator rises and the pin o releases the stop h, which in turn frees the recess i, when the vice-jaw is moved back to the right and into its starting position by the lever d.

Abstract: 444,450. Automatic control of strip tension. KRUPP GRUSONWERK AKT.- GES., F., Buckau, Magdeburg, Germany. June 17, 1935, No. 17427. Convention date, Aug. 25, 1934. [Class 38 (iv)] The winding drum of a machine for winding strip material is driven by an electric motor, the field of which is in series with a resistance which is placed out of circuit, when the tension of the material increases, by a contact device arranged in the feed path of the material and actuated thereby while additional resistances also arranged in series with the field of the motor are successively placed out of circuit by a regulator controlled by the roll of material as it is being wound so that the speed of the motor, and thus of the drum, is reduced as the roll increases in diameter. As shown, the field of the electric motor 30 driving the winding drum 1 is connected through a line 35 and a line 40, resistances 32, 36 .. 39, and a line 29 with the starter and the line 29 and a line 31, connected between the resistances 32, 36, are connected to contacts 27, 28 co-operating with a bridge 26 on the armature 25 of a coil 23 which is connected to the mains line 24 and by the line 19 with a pivoted contact device 20 co-operating with a contact 21 connected to the other mains line 22. The device 20 is carried by a pivoted lever 16 carrying a roller 15 supported by the material passing along the feed path 14 and when the tension in the material increases the contact 20 engages the contact 21 and the armature 25 is drawn up to close the contacts 27, 28 and cut the resistance 32 out of the field of the motor which consequently decreases in speed; should the material run slack in the path 14, the contacts are disengaged and the resistance 32 put into the field of the motor to increase its speed and take up the slack. The lines between the resistances 32, 36 ; 36, 37 ; 37, 38 ; 38, 39 and between the resistance 39 and the line 40 are respectively connected to contacts 34, 46 .. 49 which co-operate with annular contacts 41 .. 45 on an insulated drum 12 geared to a sector 10 on the axis of rotation 9 of a lever 8 connected to a lever 4 of one of a series of rollers 2 bearing upon the material being wound on the drum 1. The lever 4 is pivoted on an axis 5 and as the roll of material on the drum increases in diameter, the drum 12 is rotated to cause the pairs of contacts 34, 41 ; 46,42; 47,43; 48, 44 and 49, 45 to become successively engaged and thus successively cut out the resistances 36 .. 39 from the field of the motor and so reduce the speed thereof and of the drum 1 according to the increase in the diameter of the roll. The rollers 2 and arcshaped plates 3 guide the material on the drum and yield as the roll increases in diameter.

Abstract: 916,427. Frequency modulation; valve and transistor oscillating circuits. STANDARD TELEPHONES & CABLES Ltd. May 22, 1959 [May 26, 1958], No. 17505/59. Classes 40 (5) and 40 (6). A variable frequency phase-shift oscillator comprises a grounded grid amplifier with tuned anode circuit feeding through a cathode follower and a mean frequency determining series resonant crystal 3 a cathode resistor 21, to sustain oscillation. Moreover, resistor 21 is connected through a resistor 20 to HT+ so that oscillations generated are not limited by grid current. Modulation of AFC voltage applied to the grid, by changing the value of gm, changes the phase of the output relative to the cathode input so that a frequency change is produced to restore the initial phase relation round the oscillation loop. An inductor 33 across the crystal shunt resonates with the crystal shunt capacity to increase, e.g. double, the maximum frequency excursion. The cathode follower may act as a limiter and its anode output circuit may be tuned to a harmonic, e.g. twice, the frequency generated. In a modification, transistors replace the valves, and the base of the first transistor is connected to negative operating potential, so that it is always conductive and limiting is prevented.

Abstract: 170,268. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Butcher, C. A.). Oct. 9, 1920, [Convention date]. Protective arrangements. - Where polyphase apparatus, e.g. a synchronous converter 3, is applied with energy through power transformers 5, 6, 7, a protective system is used wherein a circuit interrupter 4 is tripped if a fault occurs anywhere in the circuit, but if the fault is between the transformer and the apparatus the interrupter is held open till a relay is re-set manually. The balance relay 15 of known type has two disc elements 19 normally subject to equal and opposite torques, but on the occurrence of a fault anywhere, the shaft 21 turns to complete circuit at 24 or 24a for the winding 28 of the interrupter. This winding is also energized on the operation of relays 40 and 16 but, whereas the phase relay 40 connected to the circuit on the primary side of the transformers 5, 6, 7 operates when a fault occurs on that side and returns to its normal inoperative position when the fault is removed, the relay 16, operating when the fault is on the secondary side, completes circuit for the winding 35 of a relay 34 which remains closed till re-set by hand.
