Abstract: 136,570. Angus, A. R. Oct. 10, 1917, [Convention date]. Track apparatus actuating signals on trains and for stopping trains; signalling to, and communicating between, trains.-Apparatus for signalling on or controlling the train is actuated by current shunted by conduction from the train axles, which complete a circuit between the track rails, which are supplied with current under control of the signalman. Currents of different polarity or frequency may be supplied to the track rails to permit traffic to pass in different directions, and the train apparatus is provided with a switch by means of which the circuits are arranged to permit the train to pass only in the direction for which the track is prepared. Fig. 3 (Cancelled) shows train apparatus controlled by a polarized relay 230 connected through insulated slip-rings 227, 233 on the axles 201 with the wheels 200 of a train. The circuit of the magnet 212 which restrains the operation of the train-stopping appliances passes through contacts closed by a switch 214, 221 movable in connexion with some part, such as the reversing-gear 350, the position of which accords with the direction of movement of the train, in order that the circuit may be closed only when the current received by the relay 230 is of the polarity corresponding to the direction of travel of the train along the track. The apparatus on the track for the control of traffic by the signalman is as described in Specification 119,868. According to the Specification as open to inspection under Sect. 91 (3) (a) of the Act, telephonic communication with the cabin may be established from the locomotive instrument 322, 324 by means of one or more coils 320 surrounding one or more axles.

Title: Photographic exposure control apparatus
IPC: G03B7/28
Filed: 1970-06-29
Abstract: 1313346 Photographic exposure control POLAROID CORP 29 June 1970 [30 June 1969] 31407/70 Heading G2A The diaphragm aperture and exposure time of a camera are both automatically determined using a photo-voltaic element 32 so that the product of scene brightness and aperture area increases with increasing brightness within a predetermined range and the exposure time is controlled by means responsive to scene brightness and the selected aperture area, the  aperture and exposure interval being attained sequentially. The aperture is controlled as described in Specification 1310028 by the de-energisation of an electromagnet 94 which permits the diaphragm blades to be frictionally held at an aperture value determined by the photo-voltaic element 32. At the same time, switch S 2  is switched over, switch S 4  is opened and the shutter opening blade is released. At the end of delay period determined by the light incident upon photo-voltaic element 32 a further electromagnet 124 is de-energized to allow a closing shutter blade to operate. Network 150 permits a predetermined exposur e time to be obtained, e.g. for flash operation. Photovoltaic element 32 is disposed so as to receive light through the diaphragm.

Title: Improvements in the production of very finely particled solids having low bulk density
IPC: B01J13/00
Filed: 1956-10-16
Abstract: In the process of the parent Specification, wherein an aerogel is produced by releasing the pressure on a colloidal solution at at least the critical pressure and temperature, the dispersion medium used is a mixture of water and an organic liquid and after separation of the aerogel, the vapour of the dispersion medium is rectified and the organic component reused to form fresh quantities of the colloidal solution.  The process is described in relation to a silica aerogel prepared from a sol. dispersed in a methyl alcohol-water mixture.  The silica sol is passed through a coil in a gas-fired heating chamber and has a temperature of 360 DEG  C. before decomposition.  The mixed aerogel and dispersion medium after release of pressure pass through a pipe leading to two cyclones and a dust filter, all of which are situated in a wellinsulated chamber maintained at about 200 DEG  C. with the waste heat from the heating chamber.  The vapours pass from the dust filter to a bubble tray column at the top of which substantially anhydrous methanol vapour is withdrawn.  It is condensed and returned with make-up methanol for reuse in preparing fresh quantities of the desired silica sol.

Title: Circuit for reducing the effect of delay distortion of amplifier systems on angularly modulated waves
IPC: H03F1/32
Filed: 1956-10-19
Abstract: 802,218. Frequency and phase modulation. STANDARD TELEPHONES & CABLES, Ltd. Oct. 19, 1956, No. 31876/56. Class 40 (5) In a system for reducing the effect of the delay distortion occurring in an amplifier on angularly-modulated signals, angularly modulated waves (60 mc/s. + # f ) from a source 1 are amplified in a main amplifier 2 which may include a limiter. The amplifier 2 produces a constant delay for the entire signal, plus a non- linear delay with different frequencies and the signal from 1 is delayed at 5 for a period equal to the constant delay of the amplifier. The output from the amplifier 2, which includes an error signal of frequency e which is due to the non-linear delay, is subtracted at 10 from a local signal of 80 mc/s. and the output from 5 is subtracted at 11 from a local signal of 75 mc/s., the output of mixers 10 and 11 being combined in a mixer 4 to produce a resultant error signal 5 mc/s. - e which is amplified at 6 and applied to a mixer 7. The signal 20 mc/s.- # f - # from the mixer 10 is applied via a delay device 9 which brings its error signal component into synchronism with the error signal from the amplifier 6, to the mixer 7, and the resultant output signal 15 mc/s. - # f is the original signal at a lower centre frequency, amplified and free of the error component #. In an alternative arrangement, Fig. 1 (not shown), the mixers 11 and 12 are dispensed with and the centre frequency of the signal remains unchanged. The delay device 5 may be dispensed with but enables the use of a narrower bandwidth error amplifier 6.
