Title: Improvements in or relating to apparatus for combining electromagnetic waves of different frequencies
IPC: H01P1/213
Filed: 1962-03-30
Abstract: 987,460. Band-combining circuits. GENERAL ELECTRIC CO. Ltd., and A. S. WALSH. July 1, 1963 [March 30, 1962], No. 12457/62. Heading H1W. A band-combining circuit comprises a pair 1, 2 of rectangular waveguides coupled by two spaced hybrid-couplers 3, 4, and two identical filters 9, 10 arranged one in each waveguide between the couplers. Energy in the lowfrequency band supplied to terminal 1A is divided equally between waveguides 1, 2 by the coupler 3 and propagates towards the coupler 4 which causes most of it to be fed to the terminal 2C. The filters 9, 10 have no effect on the propagation of the low-frequency energy since the stub waveguides 11, 12, 13 forming the filters have a cut-off frequency higher than the signal frequency. High-frequency energy fed to terminal 1C and divided by the coupler 4 is reflected by the filters which are designed to reject the high-frequency band. The filters are equally spaced from the coupler and the energy is reflected back with a phase-shift of 180 degress and passed by the coupler to the terminal 2C. The stubs 11, 12, 13 are tuned by pistons 14 and are coupled to the broad sides of waveguides 1, 2 with their narrow dimensions parallel to the axes of the waveguides. The broad dimensions of the stubs are equal to each other and less than the broad dimensions of the waveguides 1, 2. The narrow dimensions of the central stubs are greater than the narrow dimensions of the outer stubs. The whole apparatus may be made from two channelled brass members which meet in a plane of symmetry.

Title: Improvements in or relating to apparatus for controlling the mixing of combustible gases
IPC: G01N25/42
Filed: 1941-09-26
Abstract: 552,894. Fluid-pressure servomotor-control systems. IGRANTC ELECTRIC CO., Ltd. Sept. 26. 1941. No. 22495 Convention date. Sent. 28. 1940, [Class 135] [Also in Groups XXXV and XX] The potential heat flow factor Hp of a combustible gaseous mixture (defined as the total heating value per standard cubic foot at 30-60 saturated divided by the square root of the density) is maintained constant notwithstanding changes in the quality of the combustible constituent and in temperature and barometric pressure. The mixture supplied by a conduit 7 is burned, in a calorimeter 9, with additional air from a constant speed blower 10. This air is saturated by passing it through a humidifying chamber 11 wherein also the air and mixture are equalized in temperature. Orifices 20, 21 in the mixture and air conduits respectively are associated with opposed differential pressure responsive means whereby a valve 19 in the mixture conduit is adjusted to compensate for changes in the density of the mixture. The temperature rise resulting from the combustion operates through thermocouples 24, 25 and a galvanometer contact 26a to control a reversible electric motor 27 to adjust a valve 8 whereby air or gas of known combustible value is admitted to mix with the variable combustible (which may vary in flow rate, heating value, or density) to maintain Hp constant. A continuous interrupter 29 prevents hunting. In a modification coupled valves in the conduits supplying the two constituents are adjusted by a fluid-pressure operated controller in accordance with the flow rate of the air supply and a second fluid-pressure operated controller maintains a given proportionality in the flow of the two constituents of the mixture by adjusting a valve in the air conduit; the calorimeter operated upon an electric motor adjusting the proportionality determined by this second controller and adjusting electrical follow-up resistance in the galvanometer circuit. A pointer on this resistance gives a reading of the Hp condition of the combustible constituent.

Title: Improvements in or relating to synchronizing devices
IPC: H04L21/00
Filed: 1962-04-02
Abstract: 1,004,092. Statistical apparatus. EASTMAN KODAK CO. April 2, 1962 [April 3, 1961], No. 12512/62. Heading G4M. Groups of signals obtained by sensing columns of a record card or tape are synchronized with clock pulses to compensate for misalignment of the record or inaccurately punched holes in the record. A record card 10 is divided into four fields A, B, C, D, each of which may contain a number of 6-bit characters, the number of characters, i.e. columns in fields A, B not necessarily being the same as that in fields C, D. The fields are sensed simultaneously by photoelectric sensing stations 11A-11D. When the leading edge of the card or an identifying mark reaches 11A, clock pulses produced by a slotted disc 15 and photo-cell 18 are supplied to a ring counter 30 after an interval corresponding to the distance of the first column from the edge of the card. The groups of signals derived by sensing stations 11A-11D are temporarily stored in bi-stable circuits 40A-40D and are then read out in sequence by synchronizer 20 as the counter is stepped by the clock pulses before the next column is sensed. The groups of signals derived in sequence from read-out circuits 25A-25F are redistributed as desired by a plug-board or socket controlled by ring- counter 30. Every fifth clock pulse may be used for inserting additional data from a fixed card as described in Specification 792,861.

Abstract: 862,079. Delivery stopping apparatus for doubling &c. machines. ALLGAUER MASCHINENBAU G.m.b.H. April 14, 1959, No. 12626/59. Class 120(2) A device for stopping the top delivery roller 1 of a doubling &c. frame comprises a support lever 4, a second lever 5 pivoted in a casing 20 and forming with the first lever an elbow joint, a spring 7 bearing on the elbow joint, and a drop wire 8, which normally holds the levers in an inoperative position but moves upon thread breakage so that the lever 4 is displaced to lift the top roller 1 and to grip the thread. The spring 7 bears on a point 27 of the elbow joint so chosen that only a slight rotational force is applied to the lever 5 which is normally held against this force by the engagement of an arm 10 with the pivot shaft 11 of the drop wire 8. When the drop wire 8 falls a cut or notch in the shaft 11 releases the arm 16, which may be a leaf spring. The effective rotational force of the spring 7 increases as the lever straightens out and is sufficient to raise the roller 1. The thread is gripped between the lever 4 and roller 1 and a lip 9 contacts the lower roller 3 to prevent the thread wrapping round it. The device is reset by means of a hand lever 5. In an alternative arrangement, Fig. 5 (not shown), the thread passes round the upper roller only.

Title: Method for the manufacture of artificial wood panels built up from wood particles and bonding material, and panel manufactured by this method
IPC: B27N3/02
Filed: 1954-05-04
Abstract: A panel of wood particles and a bonding material, e.g. urea- or phenolformaldehyde or melamine resins or casein glue, is formed with a hard outer surface and a porous inner layer by using wood particles for the outer surface which contain more moisture than those used for the inner layer and pressing the particles at a first pressure, and then subjecting them to a lower pressure. During this second pressing step, the pressure may be reduced continuously.  The finished panel may remain under pressure until dry.  The bonding material for the outer surface may set more slowly than that used for the inner layer. The rate of setting being controlled by an accelerator, ammonium chloride, and an inihibitor, ammonia.  Fillers, e.g. oat, wheat or rye flour, may be added.  The viscosity of the bonding material for the outer surface may be less than that of the material for the inner layer. Thin, flat particles may be used for the surface layer, whereas the other particles may be of any shape.  Specific examples giving the proportions of compositions according to the invention, and the pressures and temperatures used in the process are including in the Specification.

In a photo-electric absorptiometer in which beams of light pass alternately to a photo-cell or cells through the substance under test and a standard, the cell output voltages being compared, the shutter which alternately obscures and passes each beam closes a switch to connect the cell output to a voltage comparator only when the cell is fully illuminated or obscured. As shown, a shutter 14 oscillating in the path of the beams of light from source 1 through the standard and test solutions 5 cuts each off in turn. The photo-cell output as each beam falls alternately on its cathode 8 is amplified at 10 and fed to a circuit comprising condenser 12 and meter 13. When one beam is totally obscured, shutter 14 engages a fixed contact to charge a condenser 12 in accordance with the photo-cell output peak. When the other beam is obscured the condenser is connected in series with the meter to the photo-cell output and if this latter is uncharged the meter shows no deflection. If not a calibrated optical wedge 6 may be adjusted, the position of this wedge indicating the density of the test solution. The two outputs may be compared on a cathode-ray tube. Separate beams and photo-cells may be used.
