Title: Apparatus and method for toughening glass
IPC: C03B27/00
Filed: 1973-07-20
Abstract: 1442320 Tempering glass sheets PILKINGTON BROS Ltd 11 July 1974 [20 July 1973] 34707/73 Heading C1M In the tempering of flat or bent glass sheets by quenching in a chilling liquid, an electrical sensor is located in the chilling liquid to provide a signal indicative of the heat transfer properties of the liquid. The sensor comprises a resistance wire 1 supplied from a stabilized current source 14. A voltage measuring device 13 measures the voltage drop across the wire 1, the voltage indicating the transfer properties of the liquid. As an alternative the voltage supply may be stabilized and the current measured. The heat transfer properties of the liquid are adjusted in response to the measurement by adding to the liquid mixtures of a high boiling point oil such as "Mobil Cylrex" (Registered Trade Mark) and a low boiling point additive such as toluene or carbon tetrachloride. The chilling liquid itself comprises the oil and a lower proportion of additive. As shown (Figs. 5A, 5B) toluene and carbon tetrachloride in containers 53 are fed into a mixing chamber 52. The mixing chamber is also supplied with oil from an overflow in the quenching tank 20 and a source of fresh oil 37. When the voltage derived from the measuring device 13 differs from a datum voltage supplied by a manually adjustable set point potentiometer, a pump 62 is activated to supply the enriched additive/oil mixture to the quench tank.

Abstract: 913,165. Determining pitch of gear teeth. ZAHNRAEDERFABRIK RENK A.G. Oct. 30, 1958 [Dec. 9, 1957], No. 34770/58. Class 106 (2). To derive the expected axial play of herring- bone gears due to pitch errors in the teeth, the differential pitch errors between the two spur rings, 1a and 1b are recorded directly by means of a pair of toothed measuring members 25, 26, in the form of separate master gears, engaging the spur rings. Differential pitch errors will produce relative rotation of the master gears as these roll over the spur rings, and are indicated on a gauge 31 carried by one master gear, a needle 30 of the gauge following a stop 28 on the other master gear. To obtain a record diagram of the relative error curve for one revolution, a recording drum 34 (Fig. 12) is provided on the casing 35-36 of an epicyclic gear system with the herringbone gear-wheel 1 as the sun-wheel, and the master gears 25, 26 and a further pair of gears 32, 33 as the planet-wheels. The basic measuring system 27-31 of Fig. 9 is used and is modified to include a stylus. It is said that the recording drum 34 is driven by rotation of the frame 35, 36 relative to the gear-wheel 1. In another embodiment, the relative rotation of the master gears is transmitted to an indicator by means of an eccentric rod carried by one of the gears and extending, with ample clearance, through an aperture in the other towards the indicator.
