Title: Improvement in calipering and recording mechanism
Filed: 1946-10-03
Abstract: 625,286. Gauging-apparatus ; recording- apparatus. SUN OIL CO. Oct. 3, 1946, No. 29560. Convention date, Oct. 26, 1945. (Classes 106 (ii) and 106 (iv)] [Also in Group XXI]  A tube calipering and recording device comprises a cylindrical housing, a cylindrical recording member within the housing, a stylus member positioned in operative relation to the recording member and means controlling said recording member and said stylus to provide a record of variations in the internal diameter of the tube by passing the housing through the length of the tube. The housing consists of three cylindrical parts, Figs. 1, 5 and 7, joined to form a long cylinder closed at the bottom by a cap 12 and at the top by a plug 13. From the plug 13, Fig. 7, extend a plurality of studs 14 supporting a block 15 having bracket arms 17, each pair of which supports a pivoted bell-crank lever 19 which at one end carries a roller 20 and at the other end engages a collar 24 of a rod 25 carried by an adjustable sleeve 26. A collar 39 on a plunger 37 urged downwardly by coiled spring in a recess 35 in the block 15 engages the bell-cranks 19, whereby the rollers 20 are urged outwardly. Each bellcrank 19 is also urged outwardly by a spring 21 carried by the block 15. The rollers 20 engage the inner wall of the tube or conduit in which the housing is moved, e.g. by gravity, axially. Upon encountering a pit or depression in the wall a roller 20 will move outwardly and its bell-crank 19 will lift the rod 25 which carries a stylus 40 in contact with the surface of a recording chart on a cylindrical drum 41, rotatable and movable axially of the housing. The stylus therefore makes on the chart a spiral line having " yags " where a pit or depression has been sensed by a roller 20. If several rollers sense pits or depressions at the same longitudinal position of the tube only the deepest will be recorded. The exact location of each recorded pit can be deduced by inspecting the chart. Recording drum driving mechanism. At the bottom of the housing, Fig. 1, there are two recesses 55, 57, through which project rollers 50 and 56 respectively, which rollers engage the inner wall of the tube being tested. The roller 50 rotates idly but the roller 56, through gearing, continuously rotates a shaft 70 which is splined to a screwed shaft 45 which carries the cylindrical drum 41. The shaft 45 engages a fixed partition 46 and consequently moves axially along guide rods 76 as it rotates. A spring 44 between a plate 75 and the partition 46 prevents backlash and an overload releasing device 63, Fig. 1, allows rotation of the driving gearing even when the drum 41 is arrested.

Title: Gear hub having two ratios engageable alaternately by back-pedal changing
IPC: B62M11/14
Filed: 1962-08-03
Abstract: 999,452. Change-speed gearing; ratchet clutches. FICHTEL & SACHS A.G. Aug. 3, 1962 [Aug. 5, 1961], No. 29915/62. Headings F2C and F2D. In a two-speed cycle hub comprising a simple ring gear, planet pinions, fixed sun gear train, oppositely directed drive and control pawls 16, 17, which are axially offset, engage surrounding control teeth 19 in, or associated with, the ring gear 14 of the train, the drive pawls 16 also being engageable with and disengageable from ratchet teeth 36 on a coaxially arranged output gear member 20 by back-pedalling, to effect change of speed. In the form shown, a step-up ratio or direct drive may be obtained. For direct drive, torque is transmitted from an input sprocket 29, fast with a carrier 4 mounting planet pinions 12 meshing a fixed sun gear 13, to a sleeve 9 fast with the carrier and journalled upon a fixed axle 1, and thence through a backpedal brake member 22 to pawls 27 engaging ratchet teeth 28 in a driven hub 7. The ring gear 14 of the planet gearing drives through the control pawls 17 to a carrier sleeve 15 journalled upon the sleeve 9 and mounting both the drive and the control pawls 16, 17, the ring 'gear 14 being so positioned angularly relatively to the carrier sleeve 15 that its teeth 19 set the pawls in the positions shown in Figs. 10 and 13, with the pawls 16 held radially inwards against the bias of springs 40 out of engagement with the ratchet teeth 36 on the output gear member 20. On back pedalling, the ring gear turns relatively to the carrier sleeve 15 in the direction 46, Fig. 10, one-way friction drag springs 18, 23, Fig. 1, holding the carrier sleeve against reverse rotation. The drive and control pawls 16, 17 then move out radially in the control teeth 19 of the ring gear 14 to the positions shown in Figs 11, 12, the pawls 16 engaging in the ratchet teeth 36 of the output gear member 20. When forward pedalling is resumed, a stepup drive is transmitted from the ring gear 14 through the drive pawls 16 to the output gear member 20, and thence through a lost-motion connection 21 to the driven hub 7. The lostmotion connection 21 prevents jamming of the hub brake when the bicycle is wheeled backwardly. To re-establish direct drive, the input sprocket 29 is again back pedalled. The drive pawls 16 are cammed radially inwards by the slopes 41 of the control teeth 19, Figs. 12, 13, out of engagement with the ratchet teeth 36 of the output gear member 20, and the initial condition is thereby restored. In one modification, Fig. 3 (not shown), the back-pedal brake is dispensed with. In another modification, Fig. 4 (not shown), direct drive and a step-down ratio are obtained from a simple planetary train having its ring gear fast with the input sprocket. In yet another modification, Fig. 5 (also not shown), giving direct drive and a stepup -ratio, the planet carrier is fast with a hub sleeve connected to the input sprocket, and the carrier sleeve is journalled through a ratchet friction spring upon the hub sleeve.

As shown in Fig. 4, two induction coils A, B are energized by the same high frequency source 51 which is cycled on and off by a low frequency control 52. Preferably in each cycle the source is on for 90% and off for 10%. The switching means comprise, for each coil a pair of SCRs 46, 47 or 49, 50 having a respective gate control 48 or 53. Operation is such that during an off period of source 51 the SCRs are off, triggering of the SCRs taking place at any desirable instant when the source is on. The SCRs 47, 50 may be replaced by diodes, or each pair may be replaced by a triac. In another embodiment shown in Fig. 6 the cycling on and off of the high frequency source 60 and the firing of the SCRs 64 to 67 are controlled by the outputs of comparators 74, 76 which each receive a signal from a ramp generator 77 and from a respective potentiometer tap 72, 75. A diode 71 determines a base bias which determines the minimum off time of the source 60, the source 60 only being cycled on when a set of thyristors is fired. In a further embodiment, Fig. 8 (not shown), the high frequency source is provided by a D.C. circuit having a pair of SCRs which are triggered at high frequency. Such a circuit may be used to control conduction heaters 101 of a cooking range as shown in Fig. 9, triacs 99 being connected in series with the inductors 101.
