Title: Address selection control apparatus
IPC: G11C8/12
Filed: 1965-03-31
Abstract: 1,108,803. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. 31 March, 1965 [6 April. 1964], No. 13608/65. Heading G4C. In a digital data store addressing system, the contents of all and some of the orders of a multi-order address register represent addresses in first and second predetermined storage areas respectively, said first area not including said second area. In the particular embodiment, a 9-bit character location in a core store is accessed by selecting one of 64 X-lines and one of 136 Y- lines, 128 of the Y-lines being associated with a main memory section and 4 of the remaining Y-lines being associated with each of two " bump " sections of the store used for registers &c. If a signal indicates that the main memory section is to be addressed, 3 address bits are decoded to select one of 8 groups of 16 Y-lines and 4 further address bits are decoded to select one line within the selected group. If a signal indicates that one of the bump sections is to be addressed, 2 of the 4 address bits just referred to are decoded to select one of the 4 Y-lines in the required bump section, prevention of this due to an error in the other 2 bits (of the 4) being prevented by forcing particular signal levels in the decoding circuitry with the aid of the down state of the signal used (in its up state) to indicate that the main memory section is required (Fig. 3, not shown). All the X-lines are common to all memory sections. Two address bits are decoded to select one of 4 groups of 16 X-lines and another 4 address bits are decoded to select one line within the selected group. A modification provides a further " main memory " section and a further address bit is used to select between the two such sections. Any effect of this bit when a bump section is selected is prevented by signal level forcing using the signals indicating the bump section required (Fig. 7, not shown).

Abstract: 167,866. Aranha, R. E. de S. May 19, 1920. Automatic - feed weighers. - Relates to apparatus for automatically measuring and delivering successive quantities of liquid, molten glass or other substance, of the kind wherein a pair of receptacles tilt about a common axis so as to receive alternately the material flowing from a feed-opening. The invention consists in providing below the tilting vessels a platform for supporting one or more resistance weights which are picked up by cam-projections on the vessels when the latter tilt. means being provided for retaining the weights on the platform when the vessels tilt in the reverse direction. As shown in Fig. 1, the two receptacles 3, 4 having a common side 6 oscillate on a shaft 5, and the upper receptacle 3 receives the feed through an opening 7, the -apparatus being retained in the position shown by the engagement of a curved cam-projection 13 on the second receptacle, with a weight 17. When sufficient material has entered the receptacle 3 the apparatus tilts, the catch 13 is. withdrawn from the weight 17, and a similar catch 12 engages and raises a second weight 16. The receptacle 4 then begins to fill and the receptacle 3 discharges through an orifice 9. A similar operation then takes place in connection with the receptacle 4 the action being continuous. Walls 21, 22 prevent displacement of the weights. In a modification, instead of outlets 9 the receptacle;s are provided with sliding discharge gates operated by fixed stops, a single weight having some lateral freedom being used instead of the two weights 16, 17. The receptacles may be jacketed for water or air cooling or for steam heating according to the substance being dealt with. When dealing with molten glass, a split bowl may be automatically closed beneath the feed-orifice whilst the apparatus is tilting, and the fixed stops for opening the sliding discharge gates are preferably arranged on the glass moulds.

Title: Improvements in frequency-modulation apparatus
IPC: H03C3/14
Filed: 1943-08-27
Abstract: 566,556. Frequency modulation. GENERAL ELECTRIC CO., Ltd., GAVIN, M. R., and HEATHCOTE, V. A. Aug. 27, 1943, No. 14059. [Class 40 (v)] In an oscillation generator comprising a primary resonant circuit coupled to a loaded secondary resonant circuit, the coupling between the two circuits is so chosen that a given change in the reactance of the primary circuit causes a maximum change in the resonant frequency of the system as a whole. As shown, the primary circuit L1, C1, C is maintained in oscillation by the valves V1, V2 and is coupled to the secondary circuit L2, C2 which is loaded by a resistance R2, e.g. an aerial. Both circuits are individually resonant at the same frequency. The coupling is so chosen that #M/R2 is equal to the square root of L1/L2, where # corresponds to the mean frequency and M is the mutual inductance of L1 and L2. The Specification shows mathematically that with this coupling the rate of change of oscillatory frequency with change of L1 or C1 is a maximum. The signal for effecting this change may be applied to vary the capacity of a condenser C in shunt to C1, or to vary the inductance L1. In a modification, Fig. 2 (not shown), the signal is applied as a variable voltage to the grids of the valves, which causes a variation in the inter-electrode capacities.

An optical viewing device has a field of view of substantially 175 degrees and comprises a tubular mount, a divergent objective giving an erect virtual image of an object and secured to one end of said mount, said objective being formed by two adjacent plano-concave lenses with their spherical concave faces directed towards each other and defining therebetween an air lens, and a convergent eye-piece mounted on the other end of the mount co-axially with the objective, said eyepiece having its front focus so located that the virtual image formed by the objective lies between said focus and the objective, a diameter substantially equal to the internal diameter of the mount, and such a focal length that the virtual image is within its field of view, said eyepiece thus forming an enlarged virtual image of the image formed by the objective, and said objective being such that the difference between the outer diameter of the objective and the diameter of the air lens is greater than or equal to where E 1  is the marginal thickness of the outer plano-concave lens of the objective and n is the refractive index of each of said plano-concave lenses. The device shown in Fig. 1 comprises a cylindrical mount 1 which may be positioned in a hole 6 formed in a door 7. The mount carries at its near end a positive eyepiece 4 and at its front end two plano-concave lenses 2, 3. The lenses 2, 3 have a field of view of substantially 175 degrees and, when conditions stated in the Specification are satisfied, the virtual image formed thereby lies within a cylinder tangential to the periphery of the air lens so that the device has the same field of view irrespective of the focal length of the eyepiece 4. The Specification as open to inspection under Sect. 91 describes also an arrangement for testing the lens combination 2, 3. This arrangement comprises two arms 9, 10, Figs. 2 and 3 (Cancelled), pivoted about a vertical pivot pin carrying a holder 8 for the lenses. Arm 10 supports a collimator 11 so that parallel rays from a lamp (not shown) are incident on lens 2 and the angular position of this arm relative to arm 9 can be measured by a protractor 17 centred on. the pivot-pin. Slidable along arm 9 under the control of a micrometer screw 15 is a carriage 12 and slidable over the carriage in a direction normal to the arm 9 is a carriage 13 on which is mounted a microscope 14, the carriage 13 also being movable under the control of a micrometer screw 16. For each angular position of the arm 10, the operator adjusts the position of the microscope until the virtual image of the lamp appears to intersect the microscope crosswires. When this is done, the distances x and h are measured. The distances x, h are noted for various angular positions of the arm 10 and from these measurements it is stated that the field of view can be determined. This subjectmatter does not appear in the Specification as accepted.
