Title: Surface elastic wave delay line oscillators
IPC: H03B5/32
Filed: 1975-08-26
Abstract: 1521478 Surface wave devices; oscillators MARCONI CO Ltd 26 Aug 1975 [26 Aug 1974] 35152/75 Headings H3U and H3F An oscillator comprises an amplifier A having in its feedback loop a surface wave delay line including an interdigital transducer, the effective length of which may be varied by switching means connected to one or more sections of the transducer. The switching means is initially closed to provide a long transducer equal to the length of the delay line so that the oscillator operates with the desired mode. The switching means is then opened, either suddenly in the case of a mechanical switch or relatively slowly with an electronic switch, to provide a short transducer. When an externally introduced phase shift, e.g. from a frequency modulator, is changed linearly over a time equal to the delay time of the surface wave line, the short transducer enables a new oscillator frequency to be established immediately. The phase shift may be obtained by deriving a variable linear combination from the outputs of two spaced detecting transducers. The transducer of variable length may comprise a short section either between two switchable longer sections, Fig. 7, or at one end of a single longer section (Fig. 8, not shown). Alternatively a short and a long section may be provided one at each side of theother transducer (Fig. 10, not shown). In another modification, Fig. 9, the short and long sections are placed side-by-side opposite an extended transducer.

Title: Vehicle door fastenings
Inventor: SMITH LEONARD LESLIE
IPC: E05B65/32
Filed: 1953-12-21
Abstract: 745,503. Door latches. WILMOT-BREEDEN, Ltd. Nov. 19, 1954 [Dec. 21, 1953], No. 35454/53. Class 44. A vehicle door fastening comprises the combination of a forked and spring-loaded pivoted latch 7, a ratchet 9 secured to the pivot pin 6 of the latch, a pawl 11 co-operating with the ratchet, a lever 13 operable from the outside of the door and a pawl releasing lever 17 both freely mounted coaxially with the pawl, a coupling lever 20 freely pivoted on the lever 13 and adapted to engage the pawl releasing lever, and a level 22, operable from the inside of the door, co-operating with the coupling lever. The latch is adapted to engage a striker pin 8 on the door fiame and is loaded by a spiral spring 10. Both the pawl 11 and the coupling lever 20 are spring-loaded. The lever 13 is adapted to be operated by a push-piece 14 and its movement is limited by a pin 15 which engages in a notch 16. The lever 22 is a bell-crank lever and both of its arms can engage the coupling lever 20. When the upper arm of the bell-crank lever 22 engages the coupling lever 20 it rotates it on its pivot and causes it to move the pawl releasing lever 17. This lever in turn bears on a pin 18 on the pawl and moves the pawl out of engagement with the ratchet 9, releasing the latch 7 so that the door can be. opened. When the push piece 14 is depressed the lever 13 is moved and since the coupling lever 20 is mounted on this lever it is also moved and operates the pawl releasing lever 17 to release the pawl so that the door can be opened. When the lower arm of the bell-crank lever 22 engages the coupling lever 20 it rotates it anti-clockwise out of engagement with the pawl releasing lever 17 and depression of the push-piece 14 cannot then open the door since although the lever 13 is moved the pawl releasing lever 17 is ineffective to disengage the pawl from the ratchet.

Patent GB-394666-A (GB)
Title: Improvements in or relating to the removal of ammonia from fuel gas
IPC: C10K3/00
Filed: 1931-12-28
Abstract: <PICT:0394666/III/1> <PICT:0394666/III/2> Ammonia is removed from fuel gas with substantially dry superphosphate which is maintained in continuous agitation.  The ammoniated product is withdrawn before any substantial amount of "reverted" phosphate is formed, say when is has an ammonia content of 4 per cent.  The presence of carbon dioxide in the gas tends to prevent reversion by assisting reaction of ammonia with calcium sulphate with formation of ammonium sulphate.  Ammonium sulphate may be mixed with the superphosphate used, and the mixture be allowed to set and then be ground before introduction into the absorber.  The fuel gas is introduced into the absorber at a temperature above the point of condensation of any moisture or hydrocarbon present therein, say at 40 DEG  C., its temperature being also such that moisture is removed from the absorber by the current of gas.  Upper and lower temperature limits are 50 DEG  C. and 30 DEG C., whilst the superphosphate may be preheated, if necessary, and its rate of feed be automatically controlled by the rate of supply of fuel gas.  Prior treatment of the fuel gas may comprise cooling with ammoniacal liquor to separate tar, scrubbing with a suspension of sulphur in ammonia to remove cyanogen compounds as ammonium thiocyanate, completion of tar separation in Cottrell precipitators, and treatment in an automatically controlled heating chamber to adjust the temperature of the gas to 40 DEG  C.  As shown in Fig. 2, the ammoniating chamber 38 comprises pairs of superposed trays 66, 67 having apertures 68, 69 respectively situated centrally and near their peripheries and rabble arms 71, 72 adapted respectively to feed superphosphate towards their centres and peripheries.  Fuel gas enters at 78 and superphosphate is fed from a hopper 73 through an air-lock 74 to a screw conveyer situated over the topmost tray.  The ammoniated product is discharged through an air-lock 80.  As shown in Fig. 5, means for controlling the rate of feed of superphosphate with the rate of supply of fuel gas comprises an orifice 87 in the gas feed pipe 78, and a U-tube 90 containing electrolyte 91, the limbs 88, 89 of which open into the pipe 78 on the two sides of the orifice. The field winding of an electric motor 96 is connected to the electrolyte 91 by wires 92, 95 and contacts 93 interconnected through resistances 94.  The electric motor drives the screw conveyer and rabble arms of the ammoniating chamber, and an increase in the rate of supply of gas cuts out one or more resistances 94 and thereby increases the feed of superphosphate.
