Title: Matrixing apparatus for a color-signal translating system
IPC: H04N9/67
Filed: 1954-11-11
Abstract: 757,014. Colour television. HAZELTINE CORPORATION. Nov. 11, 1954 [Nov. 24, 1953], No. 32688/54. Class 40 (3). In a colour television receiver for use with signals of the general type proposed in the American N.T.S.C. standards, a matrixing circuit involving only a single vacuum tube 44 is employed to derive the three colour representative signals from the sub-carrier I and Q signals. The I and Q signals are first derived in a conventional manner by detector 14 and then applied through respective low-pass filters 15, 16 to current amplifiers 40, 41, the I signal channel including also a phase inverter 20 so that the output of amplifier 40 corresponds to - I. A first pair of resistors 42, 43 applies a composite signal having predetermined relative proportions of the - 1 and + Q signals to the grid of tube 44, and a second pair of resistors 51, 52 produces a further composite signal to which a phase-inverted version of the first signal is added from across the anode load 50 of tube 44. By suitable selection of the circuit constants, red, blue and green colour-difference signals are arranged to appear at terminals 25, 26 and 27 respectively. A phase-inverted luminance signal - Y derived from the main detector 12 through amplifier 21 may be injected into the cathode circuit of tube 44 via terminals 24 and subtracts from each of the colour difference signals so that the individual red, blue and green signals are available at terminals 25-27. Video-frequency signal-peaking networks 53, 54 are connected in parallel with resistors 51, 52, and a rejection circuit 55 tuned to the subcarrier frequency is included in the anode output lead from tube 44. In a modification, Fig. 3 (not shown), the luminance signal - Y is omitted from the cathode circuit of tube 44 and is combined with the colour difference signals which then result by direct application to the cathodes of the cathode-ray tube 19. In a further modification, Fig. 4 (not shown), pairs of resistors 42, 43 and 51, 52 are replaced by potentiometers to permit critical adjustment. The Specification outlines the analysis of the circuit and includes component values for a typical design. Specification 748,060 is referred to.

In a process of making weldless tubes by hot-rolling a tubular blank on a free mandrel in a continuous rolling mill, a cog-rolling step reduces the blank by 80-90% of the required total reduction, the reduction at each stage of this step being an average of 30-40%, excluding the intermediate shaping stages, while a finishing step subsequently effects the remaining 10-20% reduction with an average reduction for each stage of about 11%. A tubular blank of either cylindrical or square external profile is first reduced by horizontal cogging stands 1, between which are mounted idle shaping roll-stands 2, each comprising a pair of horizontal rolls and a pair of vertical rolls which correct the shape of the blank to an approximately square external profile. Successive reductions of 29%, 34%, 33% and 30% are effected by the stands 1 of the cogging train, while the reduction effected in the shaping stands 2 is 5%, 5%, 3%, 3% in order of action. The stands 1 and 2 together reduce the blank by 80-90% of the required total reduction, the remaining 10-20% being effected in vertical and horizontal finishing stands 14, 15 respectively. The stands of the finishing train effect reductions of 23%, 23%, 9%, 1.5% in order of action, the last vertical stand 14 merely calibrating the finished tube. The first two cogging stands 1 are driven by a motor 3 through a reducing gear 4 while the remaining cogging stands and finishing stands are individually driven by motors 6, 17, 21. The motors 17 drive the vertical rolls of the finishing mill through orthogonal shafting 16 and bevel gearing and are mounted below the level of the stands.

Abstract: 410,215. Manifolding-devices; bookkeeping. GILBERT, A., 101, Goswell Road, London. Nov. 22, 1932, No. 33024. [Class 16.] Relates to manifold recording devices, especially for use by collectors of periodical cash payments, such as rent, in which the entries are made on a payer's recordcard, a ledger-card for the payer, and a collector's strip. A backing card or sheet has attached to its front face at two adjacent edges a record-sheet, which is carbonized wholly or partly on its rear surface, so that an entry made on the record-sheet is duplicated on a ledger card or sheet placed beneath it. A carbonized collecting-strip is placed over the record-sheet, so that an entry is simultaneously made on the collecting-strip, the record-sheet, and the ledger-card, whereby absolute agreement of the different entries is guaranteed. The backing-card 1, Fig. 1, may be foldable on a centre crease 4, and may have superposed on each wing a record-sheet 5, which is attached to the card at two adjacent edges 6, 7 for the whole or a part of their length, so as to form a pocket to receive and register a ledger-card 13. The edges may be attached by turning the margin of the sheet over the edge of the card, or vice versa, and applying adhesive, or a separate securing-strip may be used. A narrow strip of the record-sheet may be left uncarbonized along the attached edges, to avoid soiling of the ledger-card. To enable the collecting-strip and record-sheet to be registered, an appliance such as that described in Specifications 309,248, [Class 16], and 383,717 may be used, a pile of collecting-strips 17, Fig. 2, being secured to a holder 18 by clamping- means 19.

Title: Improvements relating to boiler feed water supply systems
IPC: F22D1/40
Filed: 1929-10-31
Abstract: 342,346. Feedwater supply systems for steam boilers. PENNINGTON, R., 7, Sherdley Road, Crumpsall, and MATHER & PLATT, Ltd., Park Works, both in Manchester. Oct. 31, 1929, Nos. 33080/29, 35111/29 and 41/30. [Class 123 (ii).] In a closed feed-supply system comprising a surge tank e receiving excess water from the condenser a, the centrifugal feed pump d has at all times an unrestricted delivery, and the surge tank is in communication at its upper part with the boiler steam space. Water is delivered to the boiler b through a regulator g by a booster pump f. Feed-heaters may be arranged on the suction and delivery sides of the feed pump. A system may comprise a number of feed pumps connected in parallel to a common surge tank and supplying a number of boilers connected in parallel. A tank may be placed on the suction side of the feed pumps of a number of boilers connected in parallel to receive and equalize the temperature of the feed for all the boilers. In a further modification, the feed pump d, Fig. 6, delivers into a pipe v through which water is drawn from the boiler b by a pump u, which delivers into the surge tank l and then flows into the boiler through a regulator g. The feed pump may deliver directly into the boiler, the pump u circulating water at a constant rate from the boiler through the surge tank and regulator back to the boiler. A circulation pump may be arranged in both the supply and delivery pipes of the surge tank. The water may be heated in the surge tank by an electric heater.

Title: An automatic stop motion for use in connection with bottle filling machines and the like
IPC: B67C3/24
Filed: 1930-11-04
Abstract: 362,612. Bottling &c. machines. MEADOWCROFT & SON., Ltd., W. and MEADOWCROFT, W., Regent Street, Blackburn. Nov. 4, 1930, No. 33102. [Class 125 (ii).] An automatic stop motion for a bottle-filling &c. machine is constructed so that it will be actuated by a bottle rest, when the latter is not in its lowest position, and will also be actuated by connections from the crowning &c. head when a cracked or burst bottle is presented thereunder. A vertical feeler plate A, fixed to a vertical shaft a, projects into the path of the advancing bottles and is situated slightly above the top of the bottle rests when the latter are in their lowermost position. The shaft a fixedly carries an arm a<1> having a cranked end a<2> which forms an abutment for the end of an arm a<3> rotatably mounted on a shaft a4. The arm a<3> is spring biased at a<5> and is formed with an abutment a<6> which bears against a projection a<7> on a hand-lever a<8> rigidly fixed to the shaft a<4>. Rigid with the lever a<8> is an arm D, stepped at d to engage a pin d<1> on a hand-lever d2, which operates the clutch and is spring biased at d3. The lever d<2>, pivoted at d<5> operates a sliding clutch member d<8> which through the other clutch element d<9> operates the machine. The operation is as follows: To start the machine the lever d<2> is moved to engage the clutch and the lever a<8> is moved so that the stop d engages the pin d<1> to maintain the clutch in engagement, this position being possible so long as the arm a<3> abuts against the arm a<1>. If, however, a bottle rest has not descended to its bottom position it will strike the feeler plate A, rotate shaft a, move the arm a<1> from engagement with the arm a<3> which by spring influence a<5> will withdraw abutment a<6> to the lever d2, will under spring influence d<3> move to throw the clutch out of action. To actuate the stop motion from the crowning &c. head in case a fractured bottle is presented for sealing a cylinder f, filled with oil &c., is provided with a piston F having small holes f<1> through which the oil may slowly pass. The plunger F is moved upwardly and downwardly by a bracket G attached to the sealing head. The cylinder f is maintained in a predetermined position by means of a spring f<2>, and attached to the lower end of the cylinder is a rod f<3> with a sloping end f<4> which is adapted to bear against the arm a<1> of the mechanism previously described. If no bottle is presented for sealing, or if a burst bottle is presented, the sealing head will move relatively quickly downwardly, and since the oil will not be able to pass quickly enough through the apertures f<1>, the cylinder and therefore the rod f<3> will be forced downwardly to impart motion to the arm a<1>. The mechanism previously described is again moved to stop the machine.

In a joint between sections 10, 12 of a graphite or carbon electrode, especially for furnaces, in which externally threaded carbonaceous nipple 14 engages threaded sockets in the sections, one or more cavities 17 are formed in or adjacent the end face of the socket or nipple and contain a fusible carbonaceous material, e.g. coal tar pitch, so that, on heating, the pitch passes through passages 20 over the threaded surfaces to cement them together. The passages 20 are radially disposed in the nipple or are longitudinal grooves in the threads. The pitch may be held in the cavity 17 by a wire screen 18 and carbonises when the electrode is heated. The ridges of the nipple threads do not contact the bottom of the grooves in the socket, thereby leaving a spiral passage for the melted pitch. The ends of the nipple have one or more recesses for the pitch.
