Title: Improvements in or relating to circuit arrangements for use in carrier-wave telephone systems
IPC: H04J1/14
Filed: 1953-04-02
Abstract: 724,582. Telephone transmission systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 2, 1953 [April 9, 1952], No. 9237/63. Class 40 (4). In a system using a signalling frequency outside the intelligence band, the signalling frequency is separated in a filter 2 and modulated at 6 with a frequency which increases the gap between the signalling frequency and the intelligence band, the frequency shifted signal being amplified in a signal amplifier 8 and applied to the channel amplifier 5 to which the intelligence signal is also fed; and whose output contains means 10 for separating out the signalling frequency which is then fed to a rectifier 12 whose D.C. output is applied to the signal amplifier 8 to control a signal responsive device 14. In one embodiment the channel is a carrier channel having the intelligence in the band 20.3 to 23.4 kc/s and a signalling frequency of 23.7 kc/s. The intelligence is demodulated with the normal carrier frequency of 20 kc/s. but the signal demodulator is fed with 32 kc. to convert the signal to 8.3 kc/s. If the carrier frequency of 20 kc/s. is used as the signalling frequency the demodulator 32 is fed with 28 kc/s. to convert the signalling frequency to 8 kc/s. The arrangement avoids the impedance matching difficulties for output of the amplifier 5 which are encountered when it is necessary to filter out, at this point, a signalling frequency close to the intelligence band.

Abstract: 1,216,904. Photo-electric indicating systems; electric meters; indicating apparatus. SMITHS INDUSTRIES Ltd. May 23, 1969 [Feb. 26, 1968], No. 9281/68. Headings G1A, G1J and G1U. In an indicating instrument including movable means mounted for angular displacement independence upon the value of the variable to be indicated, photo-electric means are provided to indicate when the movable means attains a predetermined position. In the arrangement shown, a moving coil current measuring meter has a pointer 12 moving over scale 16 and carrying with it a photo-electric cell 11, which moves round the outside of an endless tape 14, divided into transparent and opaque regions 14A, 14B and carried on transparent annulus 10. A predetermined angular position which might be attained by the pointer 12 is set by pointer 23 by rotation of member 17 using knob 22, at the same time the angular position of the join between the opaque and transparent regions of the tape being set. If the pointer 16 passes the value set by pointer 23, the photo-cell 11 passes from a shielded position with respect to one, 10A, of a number of light sources, to an unshielded position (or vice versa) and a change in its output occurs. The output is applied to an amplitude detector to provide a visual or audible indication. In a modification, instead of an endless tape being used, the shaft 21 carries a spool of opaque tape, the free end of which is secured to the outer surface of the annulus 10.

Void [Abridged as open to inspection under Sect. 91 of the Acts, April 23, 1932]. [Class 4.] An aircraft supported by reciprocating propellers comprises two propeller surfaces a having pivoted plates a<1>, Fig. 10, and adapted to be reciprocated by separate axles b, c, one inside the other. The plates a<1> have a cross section like that of a bird's wing and are arranged so that the reciprocating movement causes rotation of the two propelling surfaces in opposite directions, each of which has a rim of air driving cells or blades f which assist the rotation by the air forced therethrough by the reciprocation. The aircraft is steered by braking one or other of the surfaces by a brake disc o controlled by a connection inside the axles b, c to the central wheel z. A frame v is pivoted to a casing t surrounding the axles and is tilted by connections x to a control wheel y in order to change the centre of gravity of the aircraft to control the speed and allow the machine to fly backwards or forwards. The blades a' open by pivoting about axles e, Fig. 10, on upward movement of the propelling surfaces a, which are reciprocated by two racks having treadles and connected by a pinion or by a chain passing over two pinions and carrying treadles. A locking lever U when released allows both surfaces a to be engaged with the brake disc o. Passenger seats or cabins may be accommodated in the widened lower part of the frame.

A device for guiding a film past a projection aperture comprises front and rear guide plates with rounded margins, the cross sections in the direction of film feed, and transversely thereto, being such that a film can enter a free space between them but is subjected to a marginal pressure which increases to a maximum before the projection aperture is reached and is maintained at this value to the bottoms of the guide plates, at least one of which is provided with a marginal cut-away for passage of a feed claw. One form is shown in partial vertical cross-section in Fig. 6. Figs. 7, 8 and 9 are sections at AA<SP>1</SP>, BB<SP>1</SP>, CC<SP>1</SP> respectively. The front plate 1 is flat near the top but becomes curved in cross section lower down and remains so past the projection aperture, which is below the portion shown in Fig. 6, to the bottom of the plate. The top of the plate is rounded forwardly at 6, the margins 4, 5 being bent forwardly and doubled over a plate 3 formed at the top with a securing hook 11. A pin projects forwardly from the lower end of the plate 3 and is screw-threaded for securing purposes. The rear guide plate 15 is doubled back at the top, 19, to secure a spring fixing clip 21. The margins are gradually offset forwardly at 26 to press on the film margins, the central part of the plate being similarly offset lower'down, but only so far that the face does not touch the surface of the film 27.

Abstract: 1,254,581. Beam axle suspensions. CITROEN S.A. 24 Feb., 1969 [29 Feb., 1968], No. 9765/69. Heading B7D. [Also in Division F2] A leaf spring has means 6 intermediate its ends for connection thereto of a vehicle axle 3 and a plate 2 which, when an axle is present, is clamped between the axle and the spring leaf or leaves. This plate has a free end 4 whose distance from the clamping point is required to be one quarter to one half the distance from that point to an end of the spring. In the unloaded state of the spring shown in Fig. 1, this free end is out of contact with the spring and it remains just out of contact in the fully loaded state (Fig. 2, not shown). If however the axle is twisted (as a result of braking torque) the free end 4 engages the spring. In a vehicle suspension employing such a spring, the plate 4 is ineffective in normal vertical movement but it stiffens the spring if it becomes overloaded and also stiffens it when the vehicle brakes are applied.

[Class 140] Fibres of wool or other natural proteins or materials produced wholly or partly therefrom are treated with an ammoniacal solution of copper chromate, prepared by mixing an ammoniacal solution of a copper salt with an aqueous solution of a chromate, and washing with water to remove the chromium and leave copper compounds deposited in the fibres. A wetting or emulsifying agent which is capable of forming a copper complex may be included in the treating solution, this agent being subsequently removed during the removal of chromium. Examples describe the treatment of wool, and of paper-makers woollen felt, which are first wetted out with the aid of agents such as a sulphonated fatty alcohol or sulphonated castor oil.

Patent GB-98615-A (GB)
Abstract: Saponins and sapogenins are recovered from the liquid obtained by fermenting juices expressed from Agave sisalana by blowing air through the liquid to concentrate the saponins and sapogenins in a surface foam, separating chew liquid from beneath the surface foam and recovering the saponins and sapogenins from the surface foam and, if desired, hydrolysing the saponins to sapogenins. Flotation and wetting agents may be added to the liquid before the treatment with air.  The above process may be repeated in which case water may be added to the separated foam before air is passed through the liquid. The crude surface foam product may be dried to separate the saponins and sapogenins, for example at a temperature of 80 DEG  to 150 DEG C., which heating may be continued after the drying process is completed. The dried material is better suited to subsequent saponification.  In an example, the dried sediment obtained by the above process is acid hydrolysed, treated with milk of lime and then hecogenin extracted which is acetylated to hecogenin acetate.
