Title: Improvements in and relating to multiplex radio stations operating as a network
IPC: H04J1/18
Filed: 1947-08-19
Abstract: 630,399. Multiplex radio signalling. SOC. FRANCAISE RADIO-ELECTRIQUE. Aug. 19, 1947, No. 23032. Convention date, Aug. 20, 1946. [Class 40 (v)] Relates to multiplex radio systems for communication between a number of stations operating as a network, and of the type in which channels occupy adjacent bands in the radiated spectrum. The speech channels are shifted to their final position by a plurality of modulation and heterodyne stages. In the embodiment described, the twelve telephony channels comprise microphones. Mi, the 0-4 Kc/s. outputs from which are transposed, by modulators T and carrier generators #1 ... #12, to the bands 60-64 kc/s.... 104-108 Kc/s., selected by filters F#1 ... F#12. These bands are then used to modulate generators P1 ... P12 which produce carriers of 6 Mc/s.... 11.5 Mc/s. respectively at 0.5 Mc/s. intervals, and the outputs of the modulators Mo are combined. The combined spectrum is transposed by 24 Mc/s. at t to produce a 30 ... 35.5 Mc/s. band which again modulates the main 270 Mc/s. carrier at E to produce the radiated spectrum of 12 modulated waves of 300, 300.5 ... 305.5 Mc/s., the carrier and lower sideband being suppressed. At the receiver the heterodyne oscillator H operates at 291 Mc/s. to obtain, from the incoming wave, the modulated frequencies 9, 9.5 ... 14.5 Mc/s. which are fed to the channel demodulators DM. These are supplied with the 6, 6.5 ... 11.5 Mc/s. carriers from the sources P1 ... P12 respectively to produce a common intermediate frequency of 3 Mc/s. in each channel which after demodulation at AD results in the recovery of the shifted speech bands 60-64 Kc/s.... 104- 108 Kc/s. Further mixing with sources #1 ... #12 respectively, recovers the 0-4 Kc/s. speech band for each channel which is fed to the reproducers C.

Title: Improvements in or relating to milk bottle caps and method of making the same
IPC: B65D41/22
Filed: 1935-08-17
Abstract: 451,465. Milk -bottle caps. GAMMETER, J. R., 680, North Portage Path, Akron, Ohio, U.S.A. Aug. 17, 1935, No. 23198. Convention date, April 2. [Class 125 (iii)] A milk-bottle cap of yieldable material comprises a substantially flat top portion 11 and a skirt portion 12 normally extending in substantial parallelism with said top portion. The cap may be of rubber or other similar yieldable material such as that sold under the Registered Trade Mark " Pliofilm " or only the top portion may be of "Pliofilm." The skirt portion 12 is provided with an opening 13. When not in use the caps may be stacked. In use the skirt portion 12 is stretched over the bead on the neck of a bottle, and the top 11 is substantially free from tension. A convenient method of making the caps is to use a sheet of unvulcanized calendered sheet rubber material 0.015" to 0À02" thick, which is placed between dies, 19, 10. The hole 13 is then punched in the sheet. A circular die 23 having a recess 24 in which is held by suction a sheet 25 of unvulcanized rubber 0À01" thick is then moved into engagement with the sheet 18 to cut the cap out of the two sheets, the pressure between the dies sealing the edges of the two sheets together, the upper die 23 being suitably shaped as at 27. The caps are then vulcanized. Preferably they are first dusted with soapstone or similar material to prevent their sticking together and are then placed in a tubular container which may also be used for slipping the cap one on top of the other with the skirt portions facing in the same direction. The container is then slowly rotated on its axis in warm air, (e.g. 150 F.) to vulcanize the rubber. The sheets of rubber contain suitable accelerators to aid the vulcanization which may take 8 hours. If " Pliofilm " is used for the cap, heat is needed to cause the component parts to stick together, and if rubber and " Pliofilm " are both used, the rubber must be vulcanized at a low temperature, e.g. 120 F. for approximately 48 hours. " Pliofilm " caps need to be heated to about 100 F. for efficient application to the bottles. The caps may be of any suitable colours. Preferably the top portion of the cap is transparent to permit printing or an ordinary paper disc below the cap to be read with ease.

Filed: 1948-09-07
Abstract: 644,968. Friction clutches. BOULY, H. G. (Wellman Co., S. K.). Sept. 7, 1948, No. 23551. '[Class 80(ii)] [Also in Group XXII] A motor vehicle or other clutch plate of the intermediate driven disc type comprises a carrier plate with a flat centre portion 8 carrying a hub 2 and joined by spokes 11 to a peripheral portion 9 provided on opposite sides thereof with at least partly metallic friction segments 14 secured thereto at their respective centres in spaced position on each side thereof and in circumferentially staggered relation with respect to the segments on the other side. The adjacent surfaces of the segments and the portion 9 are in contact over flat areas 22 between which the portion 9 has sections 20 which, by bending to a waved shape of the portion 9 as shown or, Fig. 6, (not shown), by chamfering away of the backs of the segments, are so positioned that they act as springs resiliently opposing clutch engagement. Adjacent areas 22 have parallel adjacent edges so that the sections 20 are of uniform spring strength radially. The spokes 11, which are spiral and of decreasing circumferential width outwardly, possess torsional resilience and afford compensation for driving and driven shaft misalignment. They meet the portion 9 midway between adjacent edges of adjacent areas 22 to minimize spoke distortion on engagement. As shown; the segments 14 are secured to the portion 9 by projection welds 18, but other welding or riveting may be used. The shape of the clutch plate is such that it acts to circulate the ambient medium, whether air, oil or other liquid, for cooling purposes. The segments comprise partly metallic facings sintered on to copper or nickel-plated steel backing plates 16. The facings themselves are pressed from a mixture of non-metallic and hard and soft metallic powders, either directly into briouettes of the desired size or into larger, e.g. ring, members, which are then cut up to size. Details are given (see Group XXII) of methods of forming carrier plates, where these are to be of waved shape, by heating piles of plates, if necessary, after a preliminary hardening whilst clamped in a waved state, in a combined press and furnace such as that described in Specification 530,953;, [Group XII], forming elements of the necessary shape and thickness to give the desired final waving being interposed between the plates.

Filed: 1966-05-26
Abstract: 1,105,754. Electric kettles. W. H. B. THORNTON. 2 March, 1967 [26 May, 1966], No. 23565/66. Heading H5H. [Also in Divisions A4 and H1] An electrically operated kettle comprises thermal means heated by steam or vapour generated on boiling to actuate a switch mechanism and interrupt the current supply to the heating element and means responsive to the weight of the kettle and operable to break the heater element circuit when the water in the kettle falls below a predetermined level. To boil and discharge water automatically the shutter 12 is adjusted by finger knob 12a to close the steam vent 10 and render the bimetallic element 9 inoperative. Finger knob 22 is then pressed and control rod 21 is displaced through the abutment 23 to depress lever 18 which through link 14 rocks member 6 to the position shown in Fig. 2 to permit the contacts 5 to close. The movement of the finger knob 22 also displaces latch member 30 to a position where lug 31 is above the slot 32 and under the weight of the kettle and contents the lever moves upwards relative to the kettle and against the spring 27. When the water boils it discharges through tube 36 and when the water level falls to a predetermined level the lever 24 is moved down by spring 27 to release the latch member 31, freeing latch 30 and returning the control rod to its original position. The inner end of lever 24 exerts upward pressure on lever 18 and through link 14 rocks the switch actuating member 6 to break the heater circuit. To use the kettle for boiling without automatic discharge the tube 36 is removed and shutter 12 set to leave vent 12 open so that emergent steam on boiling causes bimetallic element 9 to operate switch actuating member 6 via plunger 11. Fold down strut 1 co-operates with the handle to lock the lid.

Title: Matrix storage device
IPC: G11C11/06
Filed: 1959-07-10
Abstract: 871,632. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. July 10, 1959 [Aug. 7, 1958], No. 23779/59. Addition to 857,302. Class 40 (9). [Also in Group XIX] The parent Specification comprises a ferrite matrix storage device in which half-writing or half-reading pulses are-applied to the storage elements via row and column wires and a common reading wire provides output signals of the same sign irrespective of the particular storage element being read, and is characterized by half-read pulses with opposite polarity being fed to a pair of row or column wires to compensate for noise pulses. The present invention includes the further feature that the matrix is divided into two parts and that the halfwriting or half-reading pulses are applied in opposite phase to corresponding rows or columns in the two parts, and that an inhibit wire is arranged with a partial loop in each of said two parts of the matrix and that an inhibit pulse can be applied to that partial loop associated with the part of the matrix including the selected storage element. Input is effected in Fig. 2 by the coincidence of half-write pulses on selected column and row wires, the column wires being connected in pairs such as a and h and fed with oppositely phased pulses whereby noise is reduced. Inhibit windings I1, I2 traverse the several rows of each half of the matrix, inhibit pulses being applied by generators JG1, JG2 to the primaries W1 of transformers U8, U9 and appearing on the secondaries W2. These secondaries W2 function as primaries for reading out pulses which are transferred by windings W3 through transformer U10 to output terminal a. The transformer U10 compensates for row interference pulses. The reading amplifier is blocked while storage or inhibition pulses are being applied. Dynamicizing read-out. The system described above is included in a dynamicizing arrangement, Fig. 3. Generator TG supplies clock pulses t0, t1, t2. The pulses t0 control CT8, CT4, CT2 to open gates whereby the storage elements are scanned by reading and writing pulses controlled through LG1-LG3 and SG1-SG3 by pulses t1, t2. Inhibit generator JG1. or JG2 applies inhibit pulses to the corresponding half of the matrix only when writing is taking place and a signal occurs simultaneously on lead st. This occurs immediately after a t1 pulse has read " 0 " from a storage element on to the output leads a. This output operates a circuit (Fig. 4, not shown) to mark the lead st. Information read out is thus immediately re-recorded.
