Title: Improvements in process of and apparatus for treating tobacco
IPC: A24B5/10
Filed: 1951-03-16
Abstract: 685,417. Pneumatic separating. AMERICAN TOBACCO CO. March 16,1951 [March 17, 1950]. No. 6399/51. Class 117 [Also in Group VI] To allow subsequent separation of tobacco leaf and stem portions in an air separator, compacted leaf portions are opened out, and leaf portions joined to stem portions are stripped therefrom, by a combined air and steam blast acting on the material to accelerate it througha conduit into which it is fed with a change of direction. Tobacco portions rejected by winnowing from the feed hopper of a cigarette-making machine are fed, as by a screw conveyer (not shown), from a container 1, Fig. 4, into a conduit 5 via an outlet 2 entering the conduit 5 at an angle to its axis.-Steam and air from lines 8, 7 moisten the tobacco and force it along the conduit 5 with a winding motion induced by a twisted vane 23, effecting the opening out and stripping referred to above. The tobacco then passes into a hood 9 having a sheet metal'entry plate 11 and air-permeable wire screen sides 10, impinges on a plywood target 16 with a sheet metal face and falls on to an endless belt 17, Fig. 2, which carries it into an air separator 18 in which air is fed upwardly from a motordriven blower (not shown) and lifts the lighter leaf portions to the top of the separator from where they deposit on a belt 20, while the heavier stem portions fall into a hopper 21 and are delivered to a conduit 22. The process may be repeated several, say four, times, each intermediate conduit 22 leading to the hood of the next apparatus and being provided at its inlet end with air and steam lines 7, 8, Fig. 2. A single belt 20 is common to all the separators.

Title: Improvements in or relating to circuit arrangements for the stereophonic reproduction of signals
IPC: H03D1/22
Filed: 1963-02-19
Abstract: 960,146. Stereophonic radio receivers. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 19, 1963 [Feb. 22, 1962], No. 6664/63. Heading H4L. A radio receiver for stereophonic signals in the form of sum and difference signals A+B and A - B, the difference signal being transmitted as an amplitude modulated subcarrier with the subcarrier suppressed together with a pilot signal of half the subcarrier frequency, is provided with means for automatically changing over the circuits for stereophonic or monaural reception according to the type of signal received and providing a visual indication. In the system described an additional separate signal on a subcarrier of 67 kc./s. also may be transmitted. Assuming that a stereophonic signal is received, after demodulation it is supplied via terminal 2 to an amplifier 8 having a 4 db. increase in gain above the pilot signal frequency of 19 kc./s. The 19 kc./s. signal is supplied via tuned circuit 12 to a frequency-doubler 9 and the subcarrier signal of 38 kc./s. developed by tuned circuit 18 is supplied via resistor 17 and tuned circuit 24, tuned to reject the 67 kc./s. signal, to the junction of the oppositely poled amplitude demodulators 27, 29. The modulation frequencies other than the 19 kc./s. pilot signal are developed across resistor 21 and supplied via resistor 16 and circuit 24 to the junction of diodes 27, 29. The pilot signal develops an appreciable negative bias on the control grid of valve 9 so that the voltage at the junction of resistor 19 and tuned circuit 18 is sufficient to ignite the gas-discharge tube 22 to provide a visible indication. The resultant positive voltage across resistor 49 cuts off diode switches 31, 32. The diode demodulators 27, 29 receive the audio-frequency sum signal in the band 0 to 35 kc./s. and the regenerated carrier of 38 kc./s. together with the sidebands of the difference signal in the band 23 to 53 kc./s. The sum signal acts as a threshold voltage shifting the operating point of the diodes 27, 29 in opposite directions to provide an addition and subtraction of the sum and difference signals so that the coherent A and B signals appear at the output circuits of diodes 27, 29 respectively. These signals are supplied via de-emphasis networks 35, 36, 38 and 34, 37, 39 respectively to the reproducing devices. If a monaural signal is received the absence of the pilot signal causes the gas tube 22 to be extinguished so that no cut-off voltage is applied to diodes 31, 32. At the same time the rise in potential at the cathode of valve 9 ensures that the diodes conduct and short-circuit the demodulators 27, 29 so that the monaural signal is applied equally to the two reproducing channels.

Title: Improvements in or relating to television apparatus
IPC: H04N5/222
Filed: 1954-03-08
Abstract: 760,416. Television. FERNSEH GES. March 8, 1954 [March 6, 1953], No. 6700/54. Class 40 (3). A television camera control unit is arranged to operate with cameras having pick-up tubes of different type and produce a signal of standard form for application to the studio control console. In Fig. 6 super-iconoscope camera 41 or image-orthicon camera 42 is connected to control unit 43 via connectors 44-46, the circuit arrangement being such that the power supply for the camera focus coil in use 48 or 50 extends from a source 47 in the control unit and returns via a current sensitive relay 49. The current consumption of the super-iconoscope is almost one tenth that of the orthicon and relay 49 responds accordingly to operate a switch 51 to connect in circuit a pre-amplifier 52 or 54 appropriate to the camera in use. The main amplifier 53 includes a circuit as shown in Fig. 5 wherein the video signal is applied via cable 4 and shading and compensating signals are added at 29. Amplification is then effected in stage 30 and the D.C. component reinserted by a clamp 13, 14 gated on by pulses 15 and 16 during the fly-back period. When the supericonoscope is employed a blanking signal is added at the anode of stage 20 to eliminate the spurious signal produced by this type of camera during fly-back. Subsequent stage 23 together with diodes 24, 25 functions to set the mean picture brightness. The final signal of standard form is obtained through stage 27. In an alternative arrangement for connecting an appropriate pre-amplifier in circuit, the hightension supply in the control unit is left floating and a different pole of the supply is earthed in each camera, the resulting potential change with respect to earth at the control unit being detected and employed to effect the change-over.

Abstract: 964,817. Protective arrangements. BRITISH INSULATED CALLENDER'S CABLES Ltd. Jan. 30, 1963 [Feb. 21, 1962], No. 6744/62. Heading H2K. An arrangement for protecting against an open circuit condition of an electric heating element 10, 11, e.g. of an electric blanket, comprises two or more gas discharge tubes 15, 16 each connected across a section of the element and having a breakdown voltage higher than the normal voltage across that section. If a section becomes open-circuited, the voltage across the associated tube increases, causing it to strike. This results in an increased voltage across the other tube or tubes causing it or them to strike, so forming a low impedance path across the supply to the element. The current through this path blows a fuse 14 to open the supply circuit to the element. Specification 964,818 is referred to.

Title: Production of organic acids by fermentation
IPC: C12P33/00
Filed: 1942-05-20
Abstract: For fermenting cellulose, hemicellulose, starch and their hydrolytic degradation products to obtain fatty acids, alcohols and ketones, a culture is used which is obtained by growing together: (a) mixed bacteria obtained from soil or from the intestinal canals of herbivorous animals or both, without any separation or selective cultivation, and (b) a pure culture chosen according to the products desired from cultures of lactic, butyric, pseudo - lactic, cellulosolytic or pectinolytic bacteria. The process of fermenting paper pulp waste liquors set forth in Specification 565,775 and the fermentation of waste cellulose materials, without first separating the insoluble matter or adding chemical nutrients set forth in Specification 565,773, are disclaimed.  The pure cultures may be isolated from the digestive canal of the panda or the sarcinas from growths on dead wood.  The fermentation may be carried out in stages. Thus, a mixed culture containing a pure lactic strain may first be used, and calcium lactate separated after adding calcium carbonate and evaporating. The molten liquor may then be fermented with a mixed culture containing a pure butyric strain and butyric acid obtained as a main product.  The use of bran, cereal waste, oilcake residues, ground husks and olive residues and their hydrolysis products is mentioned as raw material.

Abstract: 625,334. Perforating by fusion. HANCOCK, L. J., and CUMBER, W. F. March 13, 1947, No. 6961. [Class 83 (iv)] A flame-cutting burner machine of the kind in which the burner is mounted in a compound carriage and is mechanically moved over a predetermined path controlled by a template or drawing, is provided with or has attached thereto a holder for a tubular work-piece arranged horizontally with its axis parallel to the direction of movement of the lower carriage and has a burner mounted to travel in a circular path round the work-piece, the centre of rotation of the burner being substantially in the axis of the work-piece, and a drive transmission between the upper carriage and the burner to convert rectilinear movements of the upper carriage into rotary movements which are applied to the burner so as to displace it in its circular path. Holes of regular or irregular form may thus be cut in a round tube. The machine, which has an upper carriage 4 traversable transversely on rails 7 on a longitudinally traversable carriage 5 by tracer mechanism 8 co-operating with a template or pattern table 2, has mounted on the work-table 3 supports 10 carrying inclined rollers 43 in forked brackets for supporting the tube W to be cut, and either vertically adjustable or interchangeable with others of different heights. Fixed to the rails 7 is a plate 14 which carries at one end a guide-plate 16 having V-grooved rollers 28 for adjustably supporting coaxially of the work a circular runner 24 carrying a burner 12 which is radially adjustable in a bracket 29 and is counterbalanced by a weight 31. The runner is rotated by a belt 32 from a pulley 21 of equal diameter thereto on an axle 22 supported by a bearing bracket 23 on the plate 14, the axle also carrying a removable pulley 20 of diameter equal to that of the tube W and which has secured thereto at 26 a flexible band or strip 25 of metal which passes over a vertically adjustable pulley 18 mounted on the plate 14. The band 25 passes through a clamp 27 vertically adjustable on a column 37 rigid with a side bracket 39 having jaws 40 gripping a plate 41 on the front end of the burner tube 9 on the carriage 4. Traverse of the carriage 4 thus wraps the band 25 round the pulley 20 through an arc equal in length to the movement of the carriage 4 and at the same speed, the band effecting the same angular movement of the burner through the belt 32. As the lower carriage may move longitudinally, a rectangular hole may thus be cut in the tube by using a template with a rectangular outline.

Title: Improvements in burglar alarm systems
IPC: G08B13/183
Filed: 1937-03-10
Abstract: 482,322. Photo - electric burglar - alarm systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 10, 1937, No. 7070. Convention date, March 21, 1936. [Class 40 (iii)] In a burglar-alarm system, the control is effected by two beams of light close beside each other, each beam falling on a separate sensitive device, which devices are adapted to operate in such a manner that a burglar alarm is given only when the effect on the alarm circuit caused by both receivers is neutralized, e.g. when both of the beams are interrupted. A fault alarm may be actuated when only one beam is interrupted. In the arrangement shown, two similar units 1 each comprise a lamp 2 and a photoelectric cell 5. Light from each lamp illuminates the cell in the other unit after passing through lenses 3 and after reflection by the corresponding mirror or prism 4. Each cell controls, through an amplifier 6, a contact 7 or 8 respectively in an alarm circuit. The contacts are, as shown, normally closed or, if connected in series, they are normally open. In either case, both light beams must be interrupted, thereby operating both contacts together, before an alarm can be given. A fault in one of the units 1, such as the failure of a lamp, will not cause operation of the alarm. In a modification, the light sources are so arranged that the beams extend in the same direction, in which case beams of different colours may be used, the receivers being provided with opposite filters. A further arrangement, Fig. 2 (not shown), is described, in which a differential relay is used to actuate a fault alarm if only one light beam is interrupted, a separate single relay serving for the burglar alarm.
