Title: Improvements in or relating to Electronic Measuring and Indicating Apparatus
Inventor: COLES BARRY ARCLAY
IPC: G01R33/46
Filed: 1967-06-02
Abstract: 1,162,875. Gyromagnetic resonance apparatus. NEWPORT INSTRUMENTS Ltd. June 4, 1968 [June 2, 1967], No.25550/67. Divided out of 1, 074, 091. Heading G1N. [Also in Division H3] The phase comparator of Specification 1, 074, 091 is modified by applying to the averaging circuit c, a constant mark/space ratio signal of the same frequency as that from the bi-stable circuit 13. A bi-stable circuit 11 is fed with an input frequency 2f to provide outputs at frequency f which are fed to the steering inputs of the bistable circuits 12, 13. Bi-stable 13 is fed at its trigger input with the output from resonance detector 15 to produce at its output a variable mark/ space ratio signal Figs. 2VII and 2VIII (not shown) which is fed to integrating capacitor c. The constant mark/space ratio signals Figs. 2IX and 2X (not shown), is developed by bi-stable 12 and is added to that from bi-stable 13 to give a variable mark/space ratio signal at twice the frequency, Figs. 2XIII and 2XIV (not shown). Thus the integrator circuit may have a smaller time constant. The phasing between the outputs from bi-stables 12, 13 may be varied by adjusting the mark/space ratio of the oscillator signal. The output from bi-stable circuit 11 is also fed to an integrating amplifier 14 to produce a sawtooth waveform which is applied to the appropriate coil of gyromagnetic resonance apparatus 15 to modulate its magnetic field.

Abstract: 481,202. Convertible solid-fuel and gas or electric fireplaces. LANG, T. H. Sept. 21, 1936, No. 25604. [Class 126] In a convertible solid-fuel and gas or electric fireplace in which the electric or gas heating- elements d are movably mounted in recesses or cavities a<1> provided, for example, in the fireplace surround a, the arrangement is such that when the elements are moved to their service position in front of the solid-fuel grate b, the chimney opening b<1> is entirely closed so that the creation of a forced draught, with the consequent risk of rekindling a smouldering fire, is avoided. In the form shown in Figs. 1 and 3, the elements d are mounted on backings d<1> which are pivoted on vertical axes e and are tiled to match the surround a, these backings forming enclosures for the recesses a<1> when the elements are swung into their out-of-service positions. Fig. 5 shows a construction in which the elements d are housed in a recess a<1> above the chimney opening b<1>, the tiled backing d<1>, in this case, being horizontally hinged at f so that it may be swung downwardly through 180‹ to a position in which it completely closes the opening b<1>. Struts g may be provided for retaining the elements d in a horizontal position when it is desired to use them for cooking purposes. Fig. 7 shows a further modification in which the elements d are accommodated, when not in use, in a recess a' in the tiled hearth. Constructions are described in which the pivots for the movable elements are so formed that the supply of current or gas thereto is automatically turned on and off when the elements are moved to their service and out-ofservice positions respectively.

Title: Improvements in lid supporting means for cabinets or boxes
IPC: E05C17/08
Filed: 1928-09-12
Abstract: 320,493. Stone, J. A. Sept. 12, 1928. Stays.-The hinged lid of a box or cabinet is supported in an open position by a stay carrying a pin or roller which is movable in a guide member having a cam path or slot for the pin, and a movable bridging member with which the pin is adapted to engage to retain the lid in the raised position, a further opening movement of the lid causing the bridging member to move into a position which permits the pin to move for the lid to be closed. In Fig. 2 the staybar 5 is hinged to a lid 1 and a pin 7 at its lower end is movable in a slot 8 of a plate 9 secured to the cabinet 2. As shown the pin has been moved to the left by lifting the lid, until it engaged the incline 14 of the slot 24; the lid was then lowered and the pin dropped into a notch 19 of the bridge member 15 pivotally mounted at 16 on the plate 9. To close the lid it is first raised until the pin engages the side 21 of the slot 20 in the member 15; this member is thereby rocked until the edge of the notch 19 is below the level of the guide slot 8, when the lid is free to close. In the modification shown in Fig. 8 the bridge member 15 is slidable and moves with the pin 7 along the slot 8. As the lid is raised the pin is prevented from entering the lower notch 42 of the member 15 by the inclined portions 39 of the guide slot. When the lid is opened into the position shown the pin 7 is permitted to drop into the notch 28 of the guide slot. On lifting the lid to close it again the pin 7 engages the notch 42 of the member 15, which is moved until the lower inclined part of its slot is positioned to bridge the notch 28; the lid may then be closed freely, the pin 7 pushing the slide 15 to the other end of the slot 8, ready for a subsequent opening movement. Stops are provided to limit the end sliding movements ot the bridging members.
