Title: Improvements in or relating to spirometers
IPC: A61B5/08
Filed: 1953-11-20
Abstract: 742,225. Spirometers. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 20, 1953 [Nov. 25, 1952], No. 32251/53. Class 81(2). A spirometer comprising a reaction member set into rotation by the air blown into the meter and a time-indicator acting independent of the amount of air being blown in is characterised in that a member is provided which records the amount of air being blown in in relationship to the time taken. The meter shown comprises two interengaging parts-a closure member 2 housing a blade wheel 8, a magnetic brake 9, a shaft 10, transmission system 12 and locating member 13 and a cylindrical drum 1 housing a recording member and a time-indicator. The latter comprises a clockwork driven disc 25 journalled in the drum and supporting a shaft 22 which lightly engages the disc without being anchored thereto and, at its upper end, carries, freely rotatable relative thereto, a frame consisting of members 15, 17 with guides 16 rigidly secured thereto. A slide member 18 carrying a recording stylus 19 is slidable over the guides 16 such motion longitudinally of the drum being imparted by a flexible tube 27 which slides over the shaft 22 and at one end is connected to the disc 25 at 28 and at the other end is connected to the member 18 such that the member and tube are rotatable relatively. When use of the meter is required the member 2 is removed from the drum and the latter lined with recording paper. The clockwork is then wound up, a key engaging the disc shaft 26 from without the drum, so that the tube 27 is wound on the disc and the member 18 moved to its lowest position. The member 2 is then secured to the drum the locating member engaging member 15 and a temporary mouthpiece 11 is provided. The patient then blows causing the wheel 8, frame and members 18 to rotate the rotation of member 17 setting off the clockwork by the removal of a pawl which hitherto has prevented such rotation. The member 18 and stylus 19 is thus caused to simultaneously rotate and move upwards the latter movement having linear relationship with time -whilst the former movement has linear relationship with the amount of air blown in. A curve is thus drawn on the recording paper. When the member 18 has reached its highest position the clockwork is stopped by the interengagement of a lever 30 and a projection 29 on the disc 25. The stylus 19 is pivotally mounted on the member 18 and is caused to swing away from the drum wall by a projection 31 at the highest position of the member 18 whilst a projection 32 causes it to engage the recording paper at the lowest position of the member 18.

Title: Improvements in or relating to pull down devices for rotary well drilling
Inventor: RICHARDSON VERNON ELMER
IPC: E21B19/08
Filed: 1948-12-14
Abstract: 653,554. Pulldown devices for rotary well drilling. CONTINENTAL. OIL CO. Dec. 14, 1948, No. 32342. [Class 85] A pull down device for exerting pressure on drill rod during rotary well boring comprises a housing 12 bolted to a rotating quill 10 mounted on hydraulic jacks, the housing having a central passage therethrough corresponding to the cross-sectional shape of the kelly 11. Disposed within the housing between a plurality of pairs of guide plates 15, 15a are jaws 13 from which project pins 17 17a, that move in upwardly inclined slots 18, 18a formed in the guide plates, the jaws 13 being normally constrained upwards to engage the kelly by springs 19, 19a secured between the pins 17, 17a and the plates 15, 15a. The back of each jaw is also inclined upwardly and forms a rack which engages a gear segment 21 pivotally mounted on the housing so that the downward movement of the housing with respect to the kelly, and so a downward pressure, is exerted on the drill rod. Upward movement of the housing with respect to the kelly releases the jaws from the kelly so allowing a free upward movement of the housing into the next gripping position whilst rotation of the kelly is continued. In order to maintain the jaws from outof-contact with the kelly, the upper surface of the jaws have a corresponding inclination to the lower surface of an annular plate held away from the jaws by springs 26 and secured to a similar annular plate 23 below the housing. This plate 23 has formed in it a number of circumferential slots, through each of which projects a tapered rib 28 secured to a plate 27. Rotation of the plate 27 by handles 27a causes the ribs 28 to force the plate 23 downwards as they ride over the leading edges of the circumferential slots, and there is a similar downward movement of the plate 22 which forces the jaws 13 away from the kelly.

Abstract: 1459920 Cameras SEIKO KOKI K K 25 July 1974 [24 Aug 1973] 32883/74 Heading G2A A camera has a counter 6 which records a number of pulses dependant on object brightness, the count being called out in response to a first signal produced by a shutter opening member, and a second signal being produced at the termination of the celling out operation to close the shutter, a delay being introduced either between producing the first signal and starting the count or between producing the second signal and closing the shutter, in order to compensate for-the delay between the production of the first signal and the time at which the shutter actually opens. As shown, a multivibrator 2 feeds pulses to the counter 6 until a capacitor Cl has charged up through a photo-cell P to close a gate circuit 3. When the shutter is  opened a switch S3 is opened and after a delay produced by a capacitor C3 charging through a variable resistance VR, a transistor T11 is turned off to allow a frequency divider 4 to feed pulses to counter 6 to reverse the count. When the count is zero a shutter closing signal is produced. In Figs. 3 and 4 (not shown), the countdown starts as soon as S3 is opened but when a zero count has been detected by a detector circuit (7), a capacitor (C3) has to charge up before the shutter is actually closed.
