Title: Improvements in or relating to the annealing of glass articles
IPC: C03B25/06
Filed: 1926-10-29
Abstract: 289,501. United Glass Bottle Manufacturers, Ltd., Pryor, E. A. C., and Hurlbut, F. A. Oct. 29, 1926. Glass-annealing leers. - In the annealing of glassware in a tunnel leer the ware is cooled rapidly and uniformly from temperatures considerably above the lower critical annealing temperature by first subjecting the ware to the upper critical annealing temperature, and then passing it through a part of the leer, where it is surrounded or enclosed at top, bottom, and sides by a medium which permits of rapid dissipation of heat. This portion of the leer is preferably made of metal, and may be cooled externally by air or other temperature controlling medium flowing transversely around it. In the construction shown the portion of the leer beyond the fire-box or initial heating end D is formed of hollow sheet-metal sections A, B, C, of which the roof sections A and the side wall sections B are of diamond cross-section, while the floor sections C are triangular. Each top section is in communication with the two side wall sections in the same plane, and temperature-controlling medium supplied from the main F through the damper-controlled conduits F<1> is exhausted through ducts E, into which the lower ends of the sections B open. Similarly gaseous medium from the main G is supplied to the section C and exhausted through the ducts E. Damper-controlled openings A<1>, C' are provided on the outer parts of the roof and floor sections for the admission of air to dilute and cool the hot gases, and similar openings A<2>, B<2>, C<2> controlled by slides are provided in the inner parts of all the sections, so that gases can be supplied to or withdrawn from the leer chamber. Arrangements may be provided for putting adjacent sections B or C into communication so that gases can be passed therethrough in series instead of in parallel. When cold air is passed into the leer for rapid cooling below the lower critical annealing temperature, a hinged plate, adjusted according to the height of the ware, prevents travel of the air to the hotter parts of the leer. Existing leers may be modified by fitting sheet metal cooling sections adjacent the firing or entry end. Specification 250,201 is referred to.

Title: Methods of logically combining binary-valued quantities
IPC: H03K19/00
Filed: 1959-08-11
Abstract: 927,559. Waveguide switches. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1959 [Aug. 11, 1958], No. 27421/59. Class 40 (8). [Also in Group XIX] An electric circuit for plane-polarized electromagnetic waves includes a detector of waves polarized in a predetermined plane, a plurality of devices each of which when energized rotates the plane of polarization of waves travelling from the source to the detector, there being output from the detector only when the devices are energized in one or more predetermined patterns. As described the devices are ferromagnetic gyrators. A coincidence circuit (Fig. 1) comprises a source 20 of electromagnetic waves, a rectangular waveguide 22 adapted for transmission of waves having the E-vector horizontal, a gyrator a rotating the plane of the waves through 90 degrees, an absorber 26 of horizontally polarized waves, a waveguide 28 accepting only vertically polarized waves, a gyrator b, an absorber 32 of vertically polarized waves and an output waveguide 34 accepting only horizontally polarized waves. There is an output if and only if both gyrators a and b are energized. Fig. 3 shows a half adder providing sum and carry outputs from waveguides 88 and 102 accepting vertically polarized waves, and including gyrators A to A<SP>111</SP>, B, B<SP>1</SP>. For binary addition of two digits all the gyrators of a set (A or B) are energized to represent that a digit is a binary 1. It will be seen that if gyrators A or B are energized there will be an output at 88 indicating a sum of 1. If A and B are energized there will be no output at 88 since the output waveguide will not accept the horizontally polarized waves, but there will be an output at 102 indicating a carry. The branch KL including a dummy load 106 ensures a constant load on the generator, and to provide good match at D whatever operation is performed gyrators A and B (84 and 86) are energized in opposite directions. Thus gyrator A may rotate a wave 90 degrees clockwise while gyrator B rotates the wave 90 degrees anticlockwise. The apparatus below th line 5-5 of Fig. 5 may be replaced by that shown in Fig. 5. Instead of rectangular waveguides, circular waveguides including polarization detectors 122, 124, 128, 132 and 134, which produce positive sum and carry 0 and 1 output signals. Although as described all gyrators operate to rotate the place of polarization through 90 degrees, any angle of rotation may be used. Specification 821,661 is referred to. Reference has been directed by the Comptroller to Specification 821,661.

Title: Improvement in packaging machines for cigarettes
IPC: A24C5/356
Filed: 1966-06-20
Abstract: 1,119,596. Packaging-machines; conveying cigarette cassettes. ARENCO A.B. 20 June, 1966 [8 July, 1965], No. 27489/66. Headings B8A and B8C. In a packaging machine (shown in plan view in Fig. 1) cigarettes fall from cassettes 1 to a receiver 4 when the loose bottom of each cassette is slid to one side. The empty cassette 9 is then fed from an intermittently moving first conveyer 2, along which it is pushed by arms on chains 3, on to a transfer table 6, where pushers 8 transfer it across to a second conveyer 10, to be returned to a filling station. The drive of the pushers 8 is controlled by a lever (31), Fig. 4 (not shown), which operates the mechanism for sliding the loose bottom (30) of each cassette to be emptied forward into the proceeding empty cassette resting on the transfer table. Thus in its rearward position, prior to displacement of the loose bottom (30), the lever (31) operates a switch (38) which permits driving of the first conveyer 2, Fig. 1, but prevents driving of the pushers 8. In the forward position of the lever (31), Fig. 4 (not shown), after it has displaced the loose bottom (30) by its action on a slidable rod (39) carrying a hinged pawl (41) which contacts the edge of the bottom (30), a switch (37) is closed, permitting the driving of both conveyers and the pushers. The lever (31) is controlled by a cam (34), through a follower (35). A switch (28), Fig. 2 (not shown), engages a clutch controlling the drive of the pushers (8) when an emptied cassette (9) is fed on to the transfer table, and a further switch (29), operated by one of the pushers (8) when the other pusher has transferred the empty cassette on to the second conveyer 10, Fig. 1, disengages the clutch. The second conveyer 10 comprises two parallel rotating screws 11, the threads of which engage grooves or projections in the bottom surface of each cassette. These grooves or projections may be resilient so that when a cassette is stopped by previously emptied cassettes 14, 15, awaiting manual removal from the conveyer 10, the threads on the screws 11 can disengage from the grooves or projections. The drive for the pushers 8, operating through the clutch, is from one of the screws 11. The mechanism whereby the loose bottom of each cassette is slid to one side to allow the cigarettes to fall into the receiver, may alternatively be situated at the beginning of the second conveyer 10.

Title: Data processing apparatus
IPC: G09G3/00
Filed: 1969-06-02
Abstract: 1,214,449. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 2 June, 1969 [20 June, 1968], No. 27724/69. Heading G4A. In a data processing system, a plurality of sets of system conditions each include a plurality of groups of conditions, and any set can be selected and gated, a group at a time, on to a multiplex bus at either of two speeds. As described, shafts can be rotated by manual knobs, or by stepping motors under system control, to position one of ten microfilms for projection on to a display screen, discs on the shafts actuating switches to provide coded signals representing the shaft positions which select a corresponding one of ten sets of 240 one-bit conditions which are multiplexed on to a 24-bit multiplex bus, 24 at a time, under control of a binary counter, then demultiplexed from the bus under control of a Gray code counter to a 10 Î 24 array of SCR latches each driving a respective lamp embedded in the display screen. The projected microfilm image indicates the significance of the lamp indications. A common oscillator drives both counters and a sync. signal from the Gray code counter periodically resets the binary counter. The binary counter may be driven and synchronized independently of the oscillator and Gray code counter, at a higher speed; to supply system conditions over the multiplex bus at a higher speed to a 72-bit system register. The system register can communicate in both directions with the rest of the system, e.g. main or working storage, or with another system, which may be identical. The contents of the system register can be fed via the multiplex bus to the display. In the case of two identical systems, their multiplex buses are directly connected via gates responsive to either system according to a priority order, and a first of the systems may feed the display of the other with conditions selected by the other e.g. under control of an error diagnosis programme, or conditions from the first selected by the second may go to the system register of the second. The SCR inputs may also be connected to an oscilloscope, a manual override permitting the oscillator mentioned before to be inhibited (to give a continuous signal for the oscilloscope) and having an incrementing switch for incrementing the counters by one. The lamps may be replaced by a C.R.T. preceded by a buffer memory. The set of conditions and microfilm may be selected by a keyboard which controls the stepping motors, the manual knobs being dispensed with.
