Title: Procedure for the automatic sorting or recording of objects and equipment for carrying out the procedure
IPC: G06V30/224
Filed: 1968-07-03
Abstract: 1,223,458. Sensing records. SVEJSECENTRALEN. 3 July, 1968 [7 July, 1967], No. 31748/68 . Heading G4M. Code indicia, such as elongated code bars or concentric circles having a large skew tolerance for scanning, are sensed by a video camera in a single linear scan. The code indicia may be preceded and followed by asymmetric start/stop marks, e.g. each including an extra wide line. Two identical but reversed sets of code indicia may be used so that the direction of scanning is immaterial. To allow for a high degree of skew, the width of the narrow lines (and spaces) is chosen such that when scanned at an angle of 45 degrees the apparent width is less than that of a wide line (or space) when scanned at 90 degrees. Two identical sets of indicia, one being at right angles to the other, then allow for scanning in any direction. Complementary outputs Pv from video camera 1 are applied to pulse width separators 8-12 which may be preset to a voltage level corresponding to the scanned width of the extra wide start mark, Fig. 10 (not shown). A pair of AND gates 32, 35 or 33, 34, selected in accordance with the direction of scanning by separators 11, 12, supply code pulses to decoders 14a-14j corresponding to digits 0-9. Each decoder 14 has four output gates 17 which are enabled in turn by clocking circuit 18 or 19 in the order a-d or d-a in synchronism with the scanning of the decimal digits and in dependence on the direction of scanning as detected at 15, 16. Each gate 17 is coupled to a counter 23 which provides an output when the same scanning result has been obtained over a number, e.g. 5, of successive scans, and when outputs from four such counters 23 have been detected at 25, signifying that all four decimal digits have been reliably scanned, output circuits 24 are enabled to control sorting or recording apparatus. Circuit 13, 29, 30, 36 detects the scanning of a complete set of indicia to set a bi-stable circuit 37 which opens gate 38 until a number, e.g. 10, of line scanning pulses from camera 1 have been counted at 28, whereupon a reset pulse is generated at 27.

Abstract: 822,937. Electric digital-data-storage apparatus. GENERAL ELECTRIC CO. Ltd. Oct. 22, 1957 [Oct.. 22, 1956], No. 32189/56. Class 106 (1). A digit storage stage, e.g. for a shift register, includes a transformer having a first winding 7 connected in circuit with the collector of a transistor 4, and a second winding 8 in a circuit between the emitter and base electrodes of the transistor, the arrangement being such that when a positivegoing input pulse is applied to the emitter, or a negative-going pulse to the base, regeneration occurs, the collector current increasing to a maximum and then cutting off, at which instant energy stored up in the first winding of the transformer is transferred to, and absorbed by, a storage means (e.g. a capacitor 18). A third winding 9 is used to transfer the energy, via a rectifier 15, to the capacitor 18, the charge being held until a positive-going shift pulse from a generator 20 causes the condenser 18 to discharge via a second rectifier 16 and thus deliver a positive-going input pulse to the emitter of the next stage. As an alternative, the winding 8 may be in the position 8<SP>1</SP>. The storage stage may also be used as a single binary store with output signals fed back to the input for temporary storage on a capacitor 18, as shown in Fig. 3. New information is introduced on a line 28. In each embodiment transient signals are absorbed by a rectifier 26 and resistor 25.

Abstract: 392,456. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Carlson, W. La V. ; Haddonfield Manor Apartments, Haddonfield, New Jersey, U.S.A.) Nov. 15, 1932, No. 32323. Convention date, Dec. 26, 1931. [Class 40 (v).] Television and sound signals are transmitted on neighbouring carrier frequencies, for example 50,000 and 51,000 kilocycles, and are received by superheterodyne circuits. The tuning circuits 35, 36 of a high-frequency amplifier 11 are sufficiently damped to receive both carrier frequencies, and are ganged with the tuning circuit 37 of a local oscillator 14. The signals are passed through detectors 12, 13 to intermediate frequency amplifiers A, B tuned respectively to the sound and television signals. The sound signals are removed from. the tele- , vision amplifier by acceptor circuits 20a, 23a. All the television signals are passed by a detector 24 to control the emission in a cathoderay tube 26, but detectors 23, 25 are biased to respond only to the peaks of the horizontal and vertical scanning frequencies respectively. Potentiometers 32, 33, 34 control the outputs from the detectors. A gain-regulating valve 39 applies a variable grid bias to the first valve 20 in the intermediate amplifier B, and may also control the grid bias of the first valve 15 of the amplifier A in place of a potentiometer 15a. According to modifications : two heterodyne stages are used for each set of signals, Fig. 2 (not shown) ; separate carrier frequencies are used for the sound signals, the television signals and the two synchronizing signals, Fig. 3 (not shown) ; a common second detector is used for the television and synchronizing signals, Fig. 4 (not shown).

Title: Improvements in or relating to the manufacture of alkyd resins
Inventor: REISER KURT
IPC: C09D167/00
Filed: 1959-09-23
Abstract: A low molecular weight terephthalic acid-dihydric alcohol linear condensation polymer is reacted with an oil modified alkyd resin having free COOH and/or OH groups or with the alkyd-forming ingredients to form a block copolymer.  The preferred linear polymer is polyethylene terephthalate.  It may have terminal OH, COOH or ester groups.  Suitable alkyd-forming materials are phthalic anhydride, isophthalic acid, adipic acid, ethylene glycol, glycerol, pentaerythritol, trimethylolethane, trimethylolpropane, linseed oil, soyabean oil, tall oil, dehydrated castor oil, coconut oil or the corresponding fatty acids.  In examples (1) polyethylene terephthalate from ethylene glycol and excess dimethyl terephthalate was reacted with pentaerythritol, linseed oil fatty acids and phthalic anhydride to an acid value of 4.2. It yielded a hard tack-free film with cobalt and lead driers.  (2) is similar using ethylene glycol terephthalate with OH end groups.  (3) is similar to (1) but the linear polymer is added to the pre-formed alkyd.  (4) A carboxyl-terminated polyethylene terephthalate was added (a) to a mixture of soya fatty acids, pentaerythritol, ethylene glycol, and isophthalic acid, and (b) to the alkyd resin formed from those ingredients. (5) The linear polymer of Example (4) was reacted with a mixture of tall oil fatty acids; glycerol and phthalic anhydride. The resulting block co-polymer was baked with a melamine-formaldehyde resin and cobalt naphthenate to yield hard films.  (6) The linear polymer of Example (4) was reacted with linseed oil fatty acids, glycerol, isophthalic acid and ethylene glycol. (7) Two block co-polymers were formed from differing amounts of an hydroxyl-terminated linear polyethylene terephthalate reacted with tall oil fatty acids, pentaerythritol, and phthalic anhydride.  The one with the smaller amount of linear polymer had also a corresponding amount of ethylene glycol and terephthalic acid.  It had a lower acid value and a longer drying time.

Title: Electron Beam Device
Inventor: THAL HERBERT LUDWIG JR
IPC: H01J23/24
Filed: 1967-07-14
Abstract: 1,198,483. Velocity-modulated beam tubes. GENERAL ELECTRIC CO. 14 July, 1967 [29 Sept., 1966], No, 32636/67. Heading HID. An electron beam device, in particular, a travelling-wave tube, comprises input and output interaction structures having arrays of coupled elements so dimensioned and disposed that the interaction in the array is log periodic with frequency, and wherein each array defines a tunnel for a tapered electron beam. The term "log periodic" when applied to an array of elements signifies that the elements are so dimensioned or disposed that some electrical property, e.g. impedance or resonant frequency, recurs at a succession of frequencies which form a geometric series. Such an array may have wideband properties. As shown, the amplifier of Fig. 4 comprises input and output arrays 125, 125<SP>1</SP> consisting respectively of interdigitated elements 128-134 and 128<SP>1</SP>-134<SP>1</SP>. The dimensions of the elements are successively reduced according to a fixed ratio so that each array forms a linearly tapered structure, the smaller ends of the arrays being joined by a short cylindrical drift space 140. They define a biconical drift space for an electron beam 142, 143 which is so controlled by coil 141 that it is tapered in conformity with the arrays. An input is applied to the terminals 137 and an output derived at terminals 139. Different frequency components of the input and output signal interact with a respective interdigitated array at different positions along its length. In a modification (Fig. 3, not shown), the interdigitated structures are replaced by helices. Each helix is reduced in pitch and diameter from one end to the centre of the device where it is terminated by a short uniform section provided with a matched dissipative load. The two helices define a biconical drift space for a beam having the same shape as that shown in Fig. 4. In a further modification the interaction structures are in the form of resonant cavities, the frequencies of which form a geometric series and are shaped to provide a frusto-conical drift space (see Fig. 1, not shown, and Specification 1,198,482). The invention may be applied to devices using both fast and slow waves and operating in either forward or backward modes. The devices may utilize, in addition to those shown, bifilar and magnetron type arrays. The generating ratio of the geometric series on which the arrays are based preferably lies between 0À90 and 0À95.
