Filed: 1971-09-16
Abstract: 1370879 Mouthpiece cigarettes MOLINS Ltd 16 Sept 1971 [17 Sept 1970] 22973/74 Divided out of 1370878 Heading A2C A smokable rod is rolled relatively to a strip of sheet material arranged initially at an inclination to the axis of the rod to form the strip into a tube extending axially from one end of the rod and secured to it. As shown, two strips 52 are attached by glued areas 54 to the ends of a double-length cigarette rod 100 and the overlapping portions of the tubes are glued together by coatings 55. Cut-outs 56 provide lugs which prevent the burning end of a smoked cigarette from being sucked through the tube, and for the same purpose the inside of the cigarette wrapper may have a patch of fireproof gum adjacent the tube. Alternatively, or in addition, fireproof adhesive may be used at 54. A piece of cotton wool wadding or other filter material may be incorporated in the tube, e.g. between the lugs 56 and the tobacco portion, or the tube may join the tobacco rod to a filter rod. The tube may be rolled around one end of a filter and the resulting assembly joined to a tobacco rod by a separate uniting band. Cigarettes with the tubular extensions may be made singly instead of two at time as described above. Apparatus for cutting strips of sheet material and rolling them with tobacco rods is similar to that described in Specification 1370878.

Title: An automatic average extraction-rate recorder for mills engaged in the manufacture of cereal products
Inventor: LOCKWOOD JOSEPH FLAWITH
IPC: G01G19/00
Filed: 1949-09-07
Abstract: 698,323. Electric indicating systems. SIMON (HOLDINGS) Ltd., H. Aug. 30, 1950 [Sept. 7, 1949]. No. 23156/49. Class 40 (i). [Also in Group XIX] Means for recording extraction rate in cereal milling comprises means (I) for weighing grain supplied to a mill and for delivering electrical impulses after predetermined quantities of grain have been discharged, and a plurality of weighing means (O, P, Q) arranged to receive and weigh cereal products from the mill, and is characterized by electrical means for summating the weights registered by all the output weighers after each impulse delivered by the input weigher and recording the sum as a percentage of the grain input weight. A standard, mechanically-operated, input weigher I is arranged to deliver batches, preferably of multiples of 100 weight units, at regular intervals of, say, two minutes. The discharge action closes contacts DG causing the feed gates of the output weigh-balances O, P, Q to be closed, and when this action is completed, series-connected contacts xl, yl, Z<SP>1</SP> complete a circuit to cause wiper arms RO, RP, RQ on the output weigh beams to be depressed by solenoids into contact with the associated resistance elements. A circuit is then completed through these variable resistances or impedances in series to deflect a measuring instrument H by an amount proportional to the total weight of flour. A slow-to-operate relay B subsequently causes a chart-marker CM to be operated to mark a dot on a chart in accordance with the deflections of the instrument H. The circuits are then restored and the weigh-balance discharge gates opened to release the flour weighments. In the event of a fault developing in the recording apparatus a warning lamp is illuminated and means operate to prevent any interference with the operation of the mill.

Title: Use of sensing arrangements of the electronic raster-scanning kind in the investigation of a field of view
IPC: G01N15/14
Filed: 1971-04-19
Abstract: 1350096 Video signal analysis SIEMENS AG and CARL ZEISS 19 April 1971 [11 March 1970] 23695/71 Heading H4F [Also in Division G4] The densitometric analysis of a video signal is effected by an amplitude discriminator having adjustable threshold levels, signals corresponding to items lying above one threshold level being stored and then played-back and subtracted from signals from a subsequent analysis of the object corresponding to items lying above a second threshold level. In this manner items lying between the two levels are displayed or otherwise analysed. In a further embodiment only the first item struck by the scanning beam is analysed and the signal corresponding thereto stored. Upon the next analysis of the object the signal corresponding to the first item is blanked out by recalling the stored signal and the second item is evaluated and stored. The items can thus be stored according to grey value and position. In addition to displaying the selected items they may be counted, alternatively the items may be selected according to their length or area. To improve the signal-to-noise ratio the object may be scanned a plurality of times with each resulting set of signals being added to the set of signals played back from the store and then restored &c., the upper and lower surfaces of a disc store being used alternately for recording and playback. To compensate for uneven illumination of an object and/or different sensitivities of different areas of a television camera tube used for the densitometric analysis of the object, a reference signal produced by the apparatus under preliminary test condition (i.e. an empty field of view) is stored and then recalled synchronously with the analysis of the object and used to correct (e.g. for shading distortion) the resulting video signals before it is analysed. If a flying spot scanner is used instead of a television camera tube, the intensity drop at the edge of the picture is compensated. The recalled reference signal may be used to correct the sensitivity of the sensing arrangement (television camera), or regulate the illumination system or an amplifier in the signal channel. The reference signal is preferably fed via a low-pass filter to the storing device (e.g. a magnetic disc or tape store, a storage tube or a drum store) to suppress any high frequency interference voltage peaks.

Abstract: 752,170. Balancing shafts. AVERY. Ltd., W. & T. (Schenck Machinenfabrik Ges., C.). Aug. 14, 1954. No. 23696/54. Class 80(2) [Also in Group XXII] In a process for dynamically balancing a rotating mem. ber such as a tubular part 1, involving the machining of material from previously added compensating masses in accordance with data obtained from a balance testing machine, the compensating mass 2a is so distributed axially and circumferentially of the part, e.g. in continuous or discontinuous helical form, that the radial angle of its mass balance component at any point along the axis of the part 1 can be represented by the axial distance of that point from a given datum, whereby balance is achieved by feeding a milling cutter 5 on a rotating parallel shaft 7 into the compensating mass 2a whilst the part 1 is continuously rotated, the axial position of the milling cutter 5 being set on a scale 9 reading directly the required angle and cutting to a depth set on a scale 10, both scale values 9, 10 having been previously determined as angle and amount of unbalance by rotating the part in the usual balance testing machine. The helical compensating mass 2a may be balanced in itself before attachment, or its ends 11, 12 may be radial, as shown. In the former case only a single milling cutter is required. in the latter an axially spaced pair. Pairs of oppositely handed helical compensating masses may be used, each with paired milling cutters set axially in opposite directions.

Title: Improvements in luminescent silicates
IPC: C09K11/08
Filed: 1945-09-14
Abstract: 601,042. Luminescent materials. DERBY & CO., Ltd., and MEYER, H. Sept. 14, 1945, No. 23797. [Class 39 (i)] A luminescent material consists predominantly of thorium, silicon and oxygen, i.e. an activated thorium silicate. For cathode-ray excitation, the matrix is thorium silicate, a minor part of the thorium being replaced by one or_more of beryllium, magnesium, calcium, strontium, barium, zinc, cadmium or zirconium. The activator may be one or more of the elements titanium, thallium, antimony, silver, tin, lead, manganese, samarium and uranium. For blue fluorescence, titanium .1-2 per cent, preferably .4 per cent calculated as the oxide, and thallium .2-4 per cent, preferably .3 per cent calculated as nitrate give satisfactory results ; for pink fluoresence there is samarium as the oxide .1-2 per cent, preferably 1 per cent. For ultra-violet ray excitation, thorium is replaced by a minor quantity of one or more of sodium, potassium, caesium, beryllium, magnesium, calcium, strontium, barium and zirconium, and as activator there is used one or more of titanium, thallium, niobium, yttrium, lanthanum, antimony, bismuth, silver, tin and tantalum for blue fluorescence, preferably titanium in the proportion as for cathode-ray excitation. Uranium .01-1 per cent, preferably .1 per cent, as oxide in conjunction with titanium and/or antimony gives green or greenish yellow fluorescence. Samarium .1-2 per cent, preferably 1 per cent as oxide gives pink fluorescence. The activator is introduced as the silicate, fluoride, nitrate or chloride. Part of the silicate may be replaced by phosphate, by incorporating thorium phosphate or by adding ammonium phosphate. The material is made by firing at temperatures above 900‹ C., a mixture of silica and thorium oxide, carbonate, nitrate or fluoride, a flux such as an alkali fluoride being necessary in the case of the first three thorium compounds. Cations to replace the thorium are introduced as oxides, nitrates, phosphates, halides or sulphates.
