Title: Measuring high frequency signals
IPC: G01R21/01
Filed: 1979-05-09
Abstract: The method and apparatus disclosed use the nonlinear reactive characteristic of a rective component such as a varactor diode 10 to produce a signal having a frequency proportional to the amplitude of the applied high frequency signal 1. The varactor diode 10 forms a part of a resonant circuit 9 which acts as a power to frequency converter. The output of the power to frequency converter is FM demodulated 5 to provide a d.c. signal proportional to the amplitude of the applied high frequency signal 1. <IMAGE>
Patent GB-791839-A (GB)
Abstract: 791,839. Recording apparatus. FOXBORO CO. Dec. 5, 1955 [Dec. 8, 1954], No. 34850/55. Class 106 (4). [Also in Group XXXVIII] The outputs of each of two groups A, B of six thermocouples are fed to a recorder 13 via rotating switches 30, 38 and relays 54, 55 controlled by a cam-operated change-over switch 52, whereby the groups are fed alternately to the recorder 13 producing recording marks on the chart in six differently coloured inks. The motor 22 producing continuous rotation of the recorder chart and the two rotary switches 30, 38 also drives, at half speed, a cam 48 linked via a follower 50 to change-over switch 52, so that for one revolution of switches 30, 38 relay 54 is energized via switch 52 to feed the elements of group A to the measuring unit 32 and recorder 13, and for the following revolution of switches 30, 38 relay 55 is energized via switch 52 to feed the elements of group B to the meausring unit 32 and recorder 13. The cam 48 may be such as to connect, e.g., four cycles of group A thermocouples to the recorder 13 for each cycle from group B. Specification 724,089 is referred to.

Title: Collet chucks
IPC: B23B31/20
Filed: 1979-08-23
Abstract: A collet chuck or collet assembly therefor has the collect (2) provided with a co-axial and relatively rotatable annular member or nut (5) which abuts the inner end (21) of the collet (2) when in position of use in the chuck body bore (10). The nut (5) is internally threaded (50) to receive the threaded end (45) of a tool shank (4) and the action is such that on the tool encountering excess resistance to rotation the chuck body (1) and collet (2) are able to turn relative to the tool shank (4) and nut (5) thus minimising overload damage. Furthermore the abutment of the nut (5) with the collet (2) substantially prevents axial movement of the tool shank (4) especially against pull-out from the chuck. Although it may be separate, the nut (5) preferably has a relatively rotatable connection with the collet such as by snap engagement (25). <IMAGE>

Patent GB-2063299-A (GB)
Title: Electroforming mesh structures for use as camera tube electrodes
IPC: C25D1/08
Filed: 1979-12-03
Abstract: A very fine metal mesh having a high aperture-to-wire area ratio, and thus a high transmissivity is electroformed using a master patterned substrate the groove pattern of which has an average groove depth sufficient to allow the electroformation of a mesh which, for is a given weight of mesh metal, is contained wholely within the grooves and does not extend laterally beyond them across the master's face. The meshes currently in use and satisfactory for the larger tubes are not satisfactory for the smaller tubes since the methods used to produce metal mesh as fine as this, which are all variants of a basic electroforming technique in which the mesh metal is electronically deposited upon a corresponding mesh of a suitable metal that has itself been prepared by deposition in the grooves of a master mesh pattern "cut" into the surface of an inert, non-conductive substrate, suffer from a disadvantage that in the essential electrolytic deposition stage not only is the metal deposited (as is required) in and directly "above" the master pattern grooves but in addition it is deposited to either side of the grooves, so extending the eventual mesh wire laterally, and resulting in a significant reduction in the mesh's area ratio. The invention provides an electroformed micron-fine mesh having an average wire width of not more than 5 micron (preferably about 2 micron) and an average wire depth to-width ratio of 2:1 or greater (preferably about 2.5:1), and having a transmissivity at least 10% greater than a prior art mesh of comparable mesh metal weight and line frequency.
