Title: Improved apparatus for measuring and registering the density of gases
IPC: G01N9/16
Filed: 1935-09-05
Abstract: 462,311. Specific-gravity , estimating- apparatus. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 5, 1935, No. 24779. [Class 97 (iii)] In a buoyancy balance for measuring the density of gases, changes of pressure or temperature cause the centre of gravity of the balance beam to be displaced automatically in the oscillation plane of but obliquely to the balance beam so that the directing force of the balance is simultaneously altered and compensates for the effect of temperature and pressure in all positions of the balance -beam. In the form shown, the balance beam c carrying at one end the displacement sphere b and at the other end a counterweight e of the same superficial area is pivoted at d in a housing a through which the gas to be tested passes. A U-shaped tube g containing mercury hand having a quantity of gas i trapped at the top of one limb and a reservoir l open to the housing a at the top of the other limb is secured to the beam c. If the pressure in the housing a falls, the gas i expands and displaces mercury from the point k to the reservoir l immediately over the pivot d. The displacement of the balance may be transferred to a recorder outside the housing a by means of a magnetic coupling acting through the wall of the housing. In a modification the beam c carries a resilient capsule communicating through a pipe with the interior of the sphere b and adapted to rock a leaf spring to the end of which is fixed a lever terminating in a weight and oblique to the beam c.

In a remote controlled dictating installation in which any of a number of subscribers, e.g. 1 and 2 in the Figure, may select any dictating machine, e.g. 1a or 2a, by means of a selecting switch, e.g. S1 or S2, the busy or free condition of the dictating machine selected is indicated by a reversal of potential on a line associated with that dictating machine, the free potential causing the operation of a relay via a rectified circuit to cause the speech connections to be made from the subscriber to the dictating machine and also causing a reverse holding potential to be made effective to hold the relay and to indicate the busy condition of the machine. In the arrangement shown in the Figure subscriber 2 is connected to dictating machine 1a and a - ve potential therefore appears on line cl. Should subscriber 1 attempt to select dictating machine 1 by switching selector S1  to position 1 the negative potential on line C1 appears on the switch common c and, via rectifier Gr4, is routed through lamp SL1 to indicate that the machine is engaged. If subscriber 1 then switches to position 2 of selector S1 he receives a positive potential on the switch common c via line c2 and contacts bh2 and v2 which potential, via rectifiers Gr2 and Gr5 operates relay P1 which opens circuits lamp SL1 and closes the contacts p1 and p2 to complete the speech path from the subscriber to the selected dictating machine which in turn causes the energization of relays A2 and B2 in the selected machine. The energization of relay A2 closes contacts a2 to operate relay BH2 which, via contacts bh2, puts the negative, busy, potential on the line c2; relay P1 now holding via rectifiers Gr4 and Gr3 and contacts p3.

Abstract: 1349215 Cinematography BOLEX INTERNATIONAL SA 2 June 1972 [2 June 1971] 25885/72 Heading G2E A cine camera having a zoom lens (not shown) includes a lens zooming mechanism synchronized with the film movement so that zooming occurs only when light is incident on the film. As shown lens zooming is caused by rotation of the shaft 1. The shaft 1 carries ratchet wheels 2, 3 oppositely rotatable by pawls 4, 5. Springs 8, 9 bias the pawls 4, 5 towards the wheels 2, 3 respectively. A lever 19 pivoted about pin 20 carries pins 21, 22 to hold the pawls 4, 5 out of contact with the wheels 2, 3. The lever 19 is manually movable in a slot in the camera housing from the position shown in which the pawl 5 engages wheel 3 and the pawl 4 is disengaged, through an intermediate position in which both pawls are disengaged to the opposite end of the slot in which the pawl 4 is engaged and the pawl 5 is disengaged. Thus regardless of the direction of rotation of shaft 18 and the drive transmitted in one of the eccentrics 16, 17 and levers 10, 6, zooming in and out may be freely selected by the lever 19. The eccentrics 16, 17 differ in shape to permit selection of different zooming rates. The shaft 18 is also used to power the intermittent film feed and the eccentrics 16, 17 are so positioned on the shaft 18 to cause zooming only when the film is being exposed. Reference has been directed by the Comptroller to Specification 1268998.
