Abstract: 1293904 Dynamometers; pressure gauges SMITHS INDUSTRIES Ltd 3 Nov 1969 [6 Nov 1968] 52568/68 Headings G1W GIN and G1L A force balance comprises a pivoted balance arm 5, a first force producing capsule 2 for applying a force to the balance arm tending to displace the arm from a datum position about its pivot point 6 and a second force producing capsule 10 for applying a force to the arm at a variable angle. The balance is used to measure the ratio of two pressures P A , P B , the pressure P A  being applied to the interior of the capsule 2 whilst the pressure P B  is applied externally of the capsules 2, 10, the capsule 10 being evacuated. The capsule 2 is coupled to the arm 5 by a pivot 9 and the capsule 10, which is mounted on a yoke 11 pivoted about an axis 13, is coupled to a point 16 on the arm by a steel tape 15. In the datum position of the balance, indicators 24, 25 measure a value of P A /P B  equal to 1À5. A change in this ratio causes the capsule 2 to displace the arm 5 which supports a ferromagnetic bar (18) of a signal pick-up 17. The movement of the bar with respect to an electromagnet (19) causes a signal to be fed to an amplifier 20 and a servomotor 21. The motor rotates a pinion 22 and a sector gear 23 carried by the yoke to alter the position of the capsule 10 so that the force applied via the tape 15 returns the arm 5 to its datum position. To reduce the effects of temperature variation the framework supporting the balance is made of aluminium and the capsules are made of beryllium copper.

Abstract: 1,130,800. Determining dew-point electrically. GAZ DE FRANCE. Nov. 29, 1966[Nov. 30, 1965], No.53322/66. Heading G1N. The dew-point of a gas is determined by automatically controlling the temperature of a sample flow in a branch pipe at the threshold of condensation, and measuring this temperature with a thermocouple. As shown (Fig. 1), a quantity of the test gas in a duct 1 is continuously pumped into a branch pipe 2, having a tube part 4 which is externally cooled. The temperatures t 5 , t 6  and t 7  upstream, downstream and outside tube 4 are measured by resistors 5, 6, 7 respectively, and it is shown that k 1  (t 5  - t 6  ) - k 2  (t 5  - t 7  ) = # satisfies the temperature conditions, k 1 , k 2  being constants; where # = O if no condensation or vaporization occurs in tube 4, but # is negative for condensation and positive for vaporization. The resistors 5, 6, 7 are connected in a double bridge circuit (Fig. 2) to obtain k 1  (t 5  - t 6  ) and k 2  (t 5  - t 7 ),  and their difference # is derived in an amplifier 19 whose output is fed to an upstream heater 20, thereby maintaining # = O. Thus the temperature inside tube 4 is automatically maintained at dewpoint , and is measured independently by a thermocouple (not shown). In a practical embodiment described with reference to Figure 3 (not shown), a pool of condensed water is maintained at the down-stream end of tube 4.

Abstract: 1,126,659. Nailing and stapling tools. FASTENER CORP. 1 Dec., 1966 [17 Dec., 1965], No. 53789/66. Heading B4C. A pneumatically-actuated tool for driving fasteners, such as nails or staples, comprises a piston 38 slidable in a cylinder 42, 44 which is mounted in a housing 12, defining a reservoir, a valve 72 movably mounted on the piston normally closing communication between the reservoir and one end of the cylinder and a control assembly for moving the valve relative to the piston in order to permit air from the reservoir to drive the piston. The piston is formed with a body portion 56 secured to a head portion 66 by means of a stem 64 on which the valve 72 slides; the valve is loaded by a spring 84 to normally close ports 66a in the head and is of less diameter than the upper cylinder part 42 in order to provide an annular chamber 80 communicating with the reservoir via ports 42c. A trigger-operated control valve 110 is arranged to control air to and from a chamber 100 which communicates with the ports 66a. In operation, with the device in the position shown, air flows via the ports 42c to maintain the piston in the raised position. Air also flows into the chamber 100 via an open closure member 118 on the valve 110. Upon actuation of the valve 110, air in the chamber 100 flows through passages 108, 66a to act on the valve 72 thereby breaking the seal with the piston head and so allow the pressurized air in the chamber 80 to flow through the ports 66a and act on the piston head to drive it downwardly; at the end of the stroke, the lower part of the piston head closes the ports 42c (Fig. 3), the air above the piston exhausting via passages 88, 98, 94 in the piston part 56 and the valve 72 is closed by its spring 84. After a certain time air passes from the reservoir via a bleed passage 42a to act on the underside of the piston head and thereby return the latter. In a modification (Fig. 5) the trigger-operated valve 110 is replaced by an adjustable bleed valve so that the tool may be arranged to operate continuously, the speed of operation being determined by the setting of the bleed valve.

Abstract: 1387895 Local viewing; radiology G A B LARSSON 22 Nov 1972 [23 Nov 1971] 54011/72 Headings H4F and H5R In an arrangement wherein an object emitting radiation is imaged on a detector b, e.g. a scintillation plate, by a multi-channel collimator a, and wherein radiation from any point p passes through a coaxial channel a4 and adjacent offset channels, e.g. a3 and a5, the offset channels each give rise to a local image inversion about their central axis, as in a pinhole camera, so that the apparent resolution of the detected radiation distribution B for point p is reduced. By repeating the local image inversion the apparent resolution is enhanced. For example, a display c, which may be the plate b, or a cathode-ray tube display derived photo-electrically therefrom, may be provided with a matrix gh of pinholes (or lenses, Fig. 4, not shown), corresponding in number and distribution with the collimator channels to give a distribution D for recording on a photographic plate d. Synchronous movement of the collimator and matrix reduces the masking effort of the collimator channel walls to give a distribution DR. The local image inversion may also be performed electrically. In Fig. 5 (not shown), signals representing the position of a scintillation are passed to a data store and computer. The area corresponding to each collimator channel is divided into a number of cells, e.g. a 3Î3 matrix, and the signals occurring at a particular cell are transposed to the inverted image cell before being read out for display and recording. If the collimator is moved, corrective signals are supplied synchronously to the computer, Fig. 7 (not shown).
