Title: Improvements relating to speaking radio beacons
IPC: H01Q25/00
Filed: 1953-02-23
Abstract: 737,017. Radio navigation. SVENSKA AKTIE-BOLAGET GASACCUMULATOR. Feb. 23, 1953 [Feb. 23, 1952], No. 4998/53. Class 40 (7). A speaking radio beacon of the kind in which a bearing statement is transmitted periodically from a directional antenna system rotatable mechanically or electrically and a covering filled is provided which prevents erroneous bearing indications being received is provided with means for modulating the covering field with an audible tone signal of periodically varied intensity. The invention is described as applied to a speaking beacon of the type disclosed in Specification 686,886 wherein the bearing announcement signal is radiated by aerial array 25, 26 on a narrow polar diagram which as well as being rotated by the mechanical rotation of the whole aerial system by motor 30 is reversed in bearing between each announcement by synchronized cam switch 47. The covering field is radiated by array 27 coupled through slip rings 39, 40 with transmitter 41 modulated over line 62. The tone generators providing the modulation consist of two tooth wheel generators 54, 55 and their respective pick-off devices 56 and 57 from which two different frequencies are obtained. The signal from pick-off 56 is fed to the primary winding 58 of a transformer between the two yokes of which rotates a gapped steel disc 60 arranged to rotate so that maximum signal is induced in the secondary 59 when the announcement signals are radiated by the beacon and zero or minimum signal at intervening times. This variation in intensity leaves the ear more sensitive to the announcement heard at the null point than if a constant intensity modulation were used. The output of pick-off 57 is applied at intervals in the form of coded impulses by cam switch 63-64 to modulate the covering field with a sign which identifies the beacon. The number of teeth on wheel 65 is so chosen that the identification signal varies in timing relative to the beacon cycle.

Filed: 1967-02-03
Abstract: 1,173,641. Endless conveyers. BOTALAM. 3 Feb., 1967 [18 Feb., 1966], No. 5414/67. Heading B8A. Steel rods initially in a position B1 on an endless conveyer 4, have their ends engaged by a variable-pitch screw member 5 which helps to draw out each rod successively and feed it on to a series of laterally spaced endless conveyer chains F having pushers 20. Interleaved with the first six of the chains F are conveyer chains A1, A2, A3, A4 and A5. Each of these can be rotated about an axis 10 from a position alongside the adjacent chains F to a position in which the endless chain in question forms a bridge between the conveyer 4 and the endless chains F. This transistion is effected by operation of a jack 33 (Fig. 6) which causes the chain frame 24 of the chain A1 &c. in question to swing from the full line position, to the position shown in dot-dash lines. Thus by selecting the appropriate number of chain frames 24 to be placed in the bridging position (as in the case of A1 and A2 in Fig. 1), rods which are shorter than a desired length such as B5 and B7, drop down on to a conveyer belt 36 and are thus separated from the rods of normal size. The latter are delivered to arms 40 which are caused to swing down when a predetermined number of rods have been collected so as to deliver them to a recess in an endless conveyer 37.

Title: Cine-Camera for Use with Sub-Standard Size Film
IPC: G03B19/26
Filed: 1968-02-02
Abstract: 1,179,814. Cine cameras. AGFA-GEVAERT A.G. Feb.2, 1968 [Feb.4, 1967], No.5443/68. Heading G2E. In an electrically driven cine camera using sub-standard film, reversible claw feed mechanism may be coupled to a diaphragm 39 to provide fadeout and fade-in effects, there being means for regulating the feed mechanism so that the same length of film is transported during a fade-out and during the subsequent re-wind for a dissolve. The claw mechanism comprises claw members 7, 8 having ratchet teeth engaging the film and being rotatable and vertically reciprocable on shaft 9, the control 12 displacing one claw 7 into contact with the film for forward transport, and the other claw 8 for reverse. Motor 4 drives members 7, 8 vertically through crank at wheel 11, 10. The fuel regulating means consists of a switch 29, 30 in the motor circuit and actuated by a control wheel 23 through arm 26 on its shaft 22 fixed to control lever 20. Wheel 23 is biased to a starting position "O" by spring 25 on control lever 20, and is displaced to engage ratchet spring 31 and a driving pawl 34 on the claw members 7, 8 when lever 20 is moved to "out" or "reverse". At these settings, wheel 23 rotates until arm 26 trips switch 29, 30 when the claw drive stops, a predetermined length of film having been transported. Fade-in and fade-out is provided by a shutter 39 which is swung into or out of the objective beam path 1 by means of a belt and pulley connection to a second wheel 24 freely rotatable on shaft 22. With lever 20 at the "out" setting, wheel 24 engages ratchet spring 32 and driving pawl 35 and diaphragm 39 fades out the picture. At the "reverse" setting of lever 20 and with control 12 at "rewind", only wheel 23 is driven while the film is rewound by claw 8. Lever 20 is then put to "in" and control 12 to "forward", wheel 24 is then engaged by a further ratchet spring 33 and driving pawl 38 so that a "fade-in" is provided as exposure continues. Pointer 53 in the view finder indicates the movement of diaphragm 39. In a modification, wheel 24 controls the objective diaphragm only.

Title: Improvements in or relating to foamed synthetic resins
IPC: C08J9/30
Filed: 1953-02-26
Abstract: A mass of resin is foamed by the action of a foaming agent to produce a mass that will not substantially expand on subsequent extrusion and is in a partly hardened state.  This foamed mass is then extruded through one or more orifices and reduced to granules, and the granules are heated until they are substantially completely hardened. The foamed resin may be made by beating an acid catalyst with an acid-resisting foaming agent, e.g. an alcohol sulphonate, to form a stiff foam and beating urea formaldehyde or cold-setting phenolic resin into the foam.  To suppress the odour of formalin, very fine sawdust or proteins may be added to the foamed mass.  The heating may be by hot air, with or without infra-red or high-frequency heating. The reduction to granules may be effected by rotating discs or jets of fluid.  The hardened granules may be made non-inflammable by adding thereto heavy metal salts, gypsum or waterglass; or may be protectively coated with bitumen pitch; or may be mixed with water and cement or cement-sand mixture to make light-weight bricks; or may be mixed with a cold-hardening synthetic resin and a catalyst, and shaped or poured into insulation cavities.ALSO:A mass of resin is foamed by the action of a foaming agent to produce a mass that will not substantially expand on subsequent extrusion and is in a partly hardened state.

As shown in Fig. 2, the iron disc 4, comprising two rings 5 joined by ribs 7 which are themselves interconnected by a cylindrical ring 8, has the abutments formed as flanges 11; for assembly, the corrugated sheet 13 is placed in the recess 9 formed by surface 10 and flanges 11, and the disc and sheet are mounted on the hub 1, which is steel. Preferably sheet 13 is of metal. During braking, the play created between the hub 1 and the more-expanded, hotter, ring 8 is taken up resiliently by the corrugated sheet 13, which thus prevents relative rotation between hub 1 and ring 8. In Fig. 5 a single-sided disc 4a is applied to each side of a steel rail-vehicle wheel 1a. For each disc, a corrugated sheet 13a is placed inside ring 8a, the resulting sub-assembly is forcefitted on wheel-hub surface 3a and a retaining ring 11a is secured by screws 24; a first radial abutment surface is provided by a shoulder 22 on the wheel. A bearing ring 20 interconnecting the outer ends of ribs 7a is thereby located against a second radial abutment surface 23 of the wheel. In the arrangement of Fig. 7, analogous to that of Fig. 5, the cavities 12b and corrugated sheets 13b are provided at the radially-outer regions of the discs 4b.

Abstract: 324,264. Dufaux, A. Feb. 19, 1929. Vibration - dampers. - In motor vehicle shock-absorbers of the type in which the clamping pressure can be controlled at will by the driver by means of a mechanical controlling device, the variable degree of clamping of the various friction disc members shown in Fig. 1 is obtained by means of a lever 22 keyed upon a spindle 17 perpendicular to the axis of the discs and acting on a central pressure-applying spindle 15 by means of a finger engaging a notch in the spindle, the lever 22 being operated by a flexible wire 8. Endwise movement of the spindle 15 when it is actuated by the lever 22. thus compresses more or less a convex spring washer 13 and varies the pressure on the friction discs. The initial pressure on the discs may be varied by means of a nut 19 on the ends of the spindle 15, the nut being locked by a fiat spring 25. The shock-absorber shown is of the scissor type in which friction discs are connected alternatively to the two sets of arms 2a, 2b and 3<a>, 3<b>. The. finger and notch mechanism may be replaced by the rack-and-pinion mechanism shown in Fig. 5. Two or more shock-absorbers may be simultaneously controlled by a hand lever or by the apparatus shown in Fig. 6 in which separate wires are led through flexible tubes 12 to a common actuating lever. The tubes bear against an abutment 11 whilst the wires are adjusted by a member 7 engaged by a screw 4 which is rotated by the knurled button 5.
