Title: Margin stop for typewriters or the like
IPC: B41J29/50
Filed: 1960-08-02
Abstract: 894,220. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 2, 1960 [Aug. 31, 1959], No. 26707/60. Class 100(4) A margin stop arrangement consists of three margin stops adjustable on a carriage bar 1, the middle stop 30 is used with the right end stop 4 but can be made inoperative when the outer stops 3 and 4 are used. Each stop comprises a metal plate 20 with a fulcrum end 21, bearing on the rack 1, and side guides 22. A spring 29 keeps an abutment portion 16 or 12 in raised position with a block 25, connected to the two side flanges 24, in engagement with a recess in the bar 1. Pressure on the centre of the stop will release the block 25 so adjustment may be made. The central stop 30 works between two additional brackets 2 attaching the bar 1 to the typewriter carriage and when in use the abutment 16A engages the central stop 5. The stop 30 has an additional member 32 pivoted at 42 and is normally raised to position shown in Fig. 3 by a spring 44. To render the central stop ineffective the member 32 is pressed and latched down so a flat surface shown in Fig. 1 prevents the margin stop from abutting the fixed stop 5.

Filed: 1929-09-04
Abstract: 339,595. Johnson, F. A. Sept. 4, 1929. Rotary furnaces; discharging.- In a rotary furnace or dryer the material is subjected' to the action of heating-gases, which are exhausted at a point intermediate the ends, and a part of the material is then subjected to the action of a fresh supply of gases. In the apparatus shown the material is fed by a hopper D into the inner and shorter of two concentric drums A, B. The finer portions of the charge are sifted off through the screenlike portions A<1>, B<1> of the two drums, and are passed by a conveyer L to a container M, while the coarser portions pass for further heating to the drum B. Heating-gases from a fireplace C are passed to the inner drum and are exhausted through the funnel F and flue J, and a fresh supply of gases from separate fireplaces is delivered to the lower half of the furnace through the annular space between the arms A, B. In a modification (Fig. 2, not shown) the drum A extends for a short distance only into the drum B, and in a further modification (Fig. 3, not shown), in which the materials are heated out of contact with the gases, the inner drum extends the whole length of the outer drum. In the form of apparatus shown in Fig. 1 the inner end of the drum A is closed by a plate with apertures having gravity-operated doors, which are opened only when they are below the charge; or the plate may have a central opening to which the material is raised by spiral vanes. The material may be showered in the drums by lifting- blades, and its passage may be retarded by chains.

Title: Improvements in and relating to the measurement of high electrical resistance and/orthe capacity of condensers, or other values which are functions of resistance or capacity
IPC: G01R27/02
Filed: 1925-10-31
Abstract: 259,048. Inglis, J. D. Oct. 31, 1925. Actinometers.-An instrument for measuring ionization strengths comprises a two-electrode vacuum tube containing neon or other rarified gas in series with a high resistance and with a condenser in parallel either with the vacuum tube or with the resistance. On connection to a constant voltage supply, the condenser is periodically charged and discharged between definite potentials, a flash occurring in the vacuum tube at the commencement of each cycle. The period of the flashing affords data for the determination of the value of the resistance or the capacity. In the construction shown, the neon tube T is connected in series with a source a and, by means of a two-way switch s, with either a known resistance A or a resistance E to be measured. By means of a two-way switch P, a condenser B of known capacity or a condenser D the capacity of which is to be measured is connected in parallel with the resistance. A or E. The value of the resistance E is obtained by comparing the rate of flashing with the switch S on the contacts b, d respectively. For measuring ionization strengths of R÷ntgen rays or other emanations, a discharge chamber having two electrodes and filled with rarefied helium is substituted for the unknown resistance E, the frequency of flashing being measured with rays of known ionizing strength and with the rays under examination. To prevent changes in the period of flash due to change in ionization, the tube T is preferably enclosed in a box with a small observation aperture, in which box is also included a lamp or vacuum tube 0 to provide a constant ionizing effect, which reduces the starting voltage of the tube T and thus minimizes the effect of minor fluctuations in the supply voltage.
