Abstract: 1,059,647. Suspended ceilings. R. P. LICKLITER and E. ABBOTT. Aug. 7, 1964 [Aug. 7, 1963], No. 32238/64. Heading E1W. In a grid for supporting ceiling tiles, fusible shims 19 are clamped between the grid members 2 and grid member connectors 12, these shims being fusible at a predetermined temperature to remove frictional restraint against relative movement between the members 2 and connectors 12. Thereby relative movement between the ends of the members 2 is permitted to prevent buckling of the ceiling at an elevated temperature. Clamping of the members 12 is effected by tabs 16 thereon which pass through an end slot 15 in the member 2 spaced from the inner end and upper edge of the slot and through slots in a clamping plate 18 against which the tabs 16 are clinched. The arrangement permits additionally a relative downward movement of the ends of the members 2 upon fusing of the shims so that the flanges 5 can expand beneath flanges 6 of a transverse grid member 4 as shown in Fig. 3. At ends of the grid members 2 adjacent to those ends provided with connectors 12, the connectors 13 are similarly secured with interposed fusible shims, and the connectors 13 are formed to mate with the connectors 12.

Title: Improvements relating to devices for indicating the level of liquids in tanks
IPC: G01F23/34
Filed: 1938-11-07
Abstract: 520,520. Liquid-level alarms. HUGHES, R. M. (Scully Signal Co.). Nov. 7, 1938, No. 32254. [Class 123 (i)] A closed tank 2, having a filler-pipe 4 and a vent-pipe 12, is provided with an audible signalling means 14 which is placed in the path of the escaping gases and is adapted to be operated by them. One form of the signalling means is illustrated in Fig. 2. A whistle 22 is provided with central holes 24 which are adapted to cause audible signals when gas passes therethrough. A float 30 is attached to the whistle by means of bars 26 and 28 which are guided in the ring 29. When the tank is being filled with liquid, gas is displaced therefrom and passes through the whistle to the vent-pipe 12. A continuous signal is therefore given until the liquid reaches the float when said float is displaced upward and the whistle is lifted off its seating 20. The rate of passage of gas through the whistle is therefore altered, since an alternative venting-path is provided between the whistle and its seat, and the sound is either stopped or altered in pitch or intensity. A stop 38 is provided to prevent excessive upward movement of the whistle. During the filling process, when the pressure of escaping gas is heavy, the whole signalling means may be lifted from its seat, and some gas by-passed around the whistle. In such a case the sound is still given by the whistle until it is altered by the displacement of the whistle from its position of equilibrium by the further upward movement of the float 30 when the rising liquid reaches it. In a modification, in which sound is only given after the liquid-level has risen to the desired point, the whistle is connected by means of a rod to one end of a lever, the opposite end of which carries a float, the fulcrum of the lever being disposed between said rod and float. A rising liquid-level raises the float and causes the whistle to approach its seating thereby giving an audible signal. A further modification is provided by the use of a second order lever. An embodiment of the invention is shown in Fig. 7, in which the vent-pipe 12 is connected to the sleeve 18 which has the audible signalling means positioned therein. Such means consist of a valve member 58, resting on the seat 20, and connected to the tube 60 which is of predetermined length. The whistle 22 is located in the member 58 and may be surrounded by solder. During the filling process gas is driven through the tube and thence through holes 24 of the whistle, and a continuous sound is given until the end of the tube 60 is trapped by the rising liquid-level. The signalling means may be lifted from its seat if the pressure within the tank rises. In a modification, the tube may be connected rigidly to the tank with a whistle at its lower end, the side of the tube being provided with a relief valve.

Abstract: 1,123,498. Combined radio receiving and transmitting systems. G. & E. BRADLEY Ltd. 20 July, 1967 [20 July, 1966], No. 32638/66. Heading H4L. A V.H.F. transmitter-receiver is provided with an adaptor whereby it can be operated in a U.H.F. band. As described a transmitterreceiver normally transmits at 150 Mc/s and receives at 155 Mc/s and by removing the aerial rod from its socket and replacing it via plug 13 with the device shown in Fig. 2, it is converted to transmit at 450 Mc/s and receive at 455 Mc/s. When transmitting, R.F. oscillations from the V.H.F. transmitter are supplied via coupling loop 14 to a frequency-trebler 15 using a varactor diode or step diode in known manner. Signals received at the aerial 17 are supplied to a frequency-changer 16 co-operating with a local oscillator 18, the 155 Mc/s difference frequency being selected for application via the plug 13 to the receiver. The frequencychanger is powered by a battery 19 which may be charged by rectifying at 21 a portion of the transmitted R/F, or the standing current of a varactor diode used in the frequency-multiplier may be utilized.

Title: Improvements in radio receivers
IPC: H04B1/26
Filed: 1935-11-25
Abstract: 468,209. Valve circuits for wireless reception. ACE AMPLIFIERS, Ltd. Nov. 25, 1935, No. 32639. Convention date. Dec. 13, 1934. [Class 40 (v)] In a superheterodyne receiver employing a double frequency change the local oscillation for the second frequency changer is derived from the signal through a further frequency changing stage. Fig. 1 shows a frequency changer A feeding frequency changers B, C, the local oscillation for the frequency changer B being taken from the output of the frequency changer C after removal of the sidebands by filter E. In this way signals pass through the intermediate frequency channel F only when the signal provides a sustained carrier to supply the local oscillation to the frequency changer B. This produces a muting effect between successive Morse symbols and for direction finding enables a sharp minimum to be obtained. Fig. 2 shows pentagrids 12, 13 as the frequency changers B, C, of Fig. 1. a piezo-electric crystal 28 serving as the selective device. Automatic volume control potential is obtained from a diode 25 fed from the anode 22, and forming one of diodes in a valve 20 which also serves a signal detector and audio-amplifier. Since sidebands are largely absent from the input to the diode 25 lower values of filters can be used and rapid compensation for fading and response of a visual tuning indicator is obtained. The signal noise ratio can be controlled by varying the amplitude of the input to the grid 17 which can be conveniently effected by varying the conversion conductance by cathode resistance 29 which controls grid potentials. Instead of the piezo-electric crystal 28 a dynatron or other negative resistance device may be used to obtain selectivity and may be used with the frequency changer 13 switched off to generate the local oscillation or to beat with the normal local oscillations as a sensitive indication of correct tuning or to replace a visual tuning indicator. In a modification, Fig. 3 (not shown), a wide separation between the intermediate and other frequencies used is obtained by arranging a further frequency change between the filter E and the frequency changer B, Fig. 1, to which energy from the local oscillator feeding frequency changer C is also fed. The Specification as open to inspection under Sect. 91 also describes arrangements of two frequency changers in cascade in which a signal and a local oscillation are applied to the first frequency changer and the modulation products produced are applied to the second frequency changer from the output of which a modulated frequency corresponding either to the local oscillation or to twice this frequency is selected. This subject-matter does not appear in the Specification as accepted.

[Also in Division H2] In a control circuit for arc welding, an electrode feed motor 1 is connected to the welding supply 16 by contacts 26 of a contactor 6, the release of the contactor 6 is delayed until after the arc ceases, control means regulating the welding supply 16 and the feed motor 1 comprise a control relay 12 connected by a starting switch to the welding supply 16, and normally open contacts 13 of the control relay 12 are located in the circuit of the contactor 6. Actuation of a switch 24, Fig. 1, and the start switch 9, connects the control relay 12 to a separately excited D.C. generator 16 and energizes contactor 6. Thereupon the generator 16 is connected in parallel to the shielding gas valve 5, the electrode 25 and the feed motor 1 and the arc strikes. Where the shielding gas is carbon dioxide, a gas preheater 19 is used. To reduce the welding current, start switch 9 is released to de-energize relay 12, to shunt a resistor 4 in the shunt circuit of the feed motor 1 to reduce the feed rate and to insert resistance in the field of the generator 16 to reduce the welding voltage. To stop welding, a switch 20 is actuated to short circuit the feed motor armature and to disconnect the contactor 6. The arc burns back and extinguishes and after a delay of 1-2 seconds produced by a condenser 7, the contactor 6 returns the circuit to normal. In a modification, Fig. 2, the release of the start button 32 reduces the welding current by releasing the control relay 12 as before and a relay 27 energizes to hold the contactor 6. To stop welding, the start button 32 is again operated. Relay 12 operates and is followed by a relay 28 which shunts the armature of the feed motor and disconnects the contactor 6. In a further modification, Fig. 3 (not shown), the reduction of welding current is effected directly by relay 27 which is energized directly by release of the start button.
