Title: Improvements in or relating to pre-stressed concrete pipes or other precast concrete products
IPC: B28B21/64
Filed: 1945-01-12
Abstract: 587,737. Reinforced concrete. STANTON IRONWORKS CO., Ltd., CORNELIUS, F. B., and SUDBURY, W. M. Jan. 12, 1945, No. 1019. [Class 20 (iv)] [Also in Group XXII] The reinforcement wire of reinforced concrete members is pre-tensioned to a predetermined degree by feeding it from a drum b through a reducing die f in a manner analogous to that of wire drawing. In the form shown the wire g, while still tensioned, is wound around a preformed concrete pipe a to form a wound reinforcement. Alternatively, it may be anchored at both ends, while still tensioned, in a mould for a concrete beam &c. in which the wire serves for longitudinal reinforcement. The die, which may be of mild steel with a tungsten carbon insert, is carried by a slidable head e connected to a dynamometer i and to a carriage c which traverses a screw d driven from the mandrel b or driving heads supporting the pipe a. Two slidable heads, each carrying a reducing die, may be positioned at opposite sides of the pipe so as to equalise radial thrusts on the pipe during winding; one head may be slightly in advance of the other whereby the turns of one spiral are positioned between those of the other thereby forming two complete spirals similar to a two start thread. A pipe comprising a thin steel sheet enclosing a concrete lining may be similarly wound. High tensile steel wire is used; it is stated that if the original size is 9 I.S.W.G., by reducing the diameter to .124 in or .120 in. a tension of 51 or 65 tons per sq. in. respectively, is roduced

Abstract: 363,166. Cutting synthetic resin. HEROLD AKT..-GES., 30, Hufnerstrasse, Hamburg, Germany. Jan. 12, 1931, No. 1082. Convention date, Jan. 11, 1930. [Class 87 (ii).] Blocks of synthetic resin are cast in moulds of lead or other soft metal and the block and mould together are then sliced into sheets on a cutting-machine such as that used for cutting celluloid. To maintain the resin in the mould it may be cast on to bars of synthetic resin alone or synthetic resin mixed with fillers such as linen, paper, asbestos, fibrous materials, and the like. Synthetic resin scrap may be used and the bars may be reinforced with metal. Fig. 1c shows one example in which the block a is cast on to two bars c of synthetic resin placed in recesses in the mould. Fig. 2d shows wedge-shaped bars of lead d interposed between the bars c of resin to prevent fracture of the latter under the moulding pressure. Tapered lead bars d, Fig. 3c, may also be used at the sides to prevent the cast block from rising in the mould. Fig. 5c illustrates movable and fixed clamping members e, f respectively for fixing the mould-unit in the cutting-machine. In another arrangement the mould-unit is received inside a framework so that it is engaged on all four sides by screw-adjusted clamping bars. In the Specification as open to inspection under Sect. 91 (3) (a), Fig. 7c (Cancelled) shows wedgeshaped metal bars b arranged in the top part of the mould and the block cast over them. In a modified form of this construction some of the parallel bars are fixed, and some movable and they are all provided with projecting ends for securing the block to the cutting-table. Fig. 8c (Cancelled) shows a series of dovetailed iron bars m placed in the bottom of the mould to form the base of the block a. Fig. 11a (Cancelled) shows a series of iron bars l at the bottom of a lead mould b, some of the bars being fitted with screws o for securing the mould-blocks on to the cutting-table. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the generation of colour television signals
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N9/07
Filed: 1956-01-13
Abstract: 852,505. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 8, 1957 [Jan 13, 1956], No. 1187/56. Class 40(3). In an arrangement for generating simultaneous type colour television signals the scene to be televised is imaged on the charge storage electrode 2 (Fig. 1) of the pick-up tube via a rotating colour filter 6 consisting in one embodiment, as shown in Fig. 2, of a sector 7 transmitting green, a sector 8 transmitting green overall and, in arcuate strips 11, yellow and a sector 9 transmitting green overall and, in arcuate strips 13, cyan, so that the tube output signals consist of a video frequency signal 24 (Fig. 4), due to the overall transmission of the filter and two carrier wave signals, 25, 27 (Fig. 1), having frequencies dependent on the "pitch" of the strips 11 and 13 and modulated respectively by the red and blue components. The latter signals are selected by band-pass filters 17,18 respectively and after demodulation in 19 and 20 provide red and blue component colour signals at terminals 28, 29 respectively. The outputs of the demodulators 19, 20 are also supplied via amplifiers 22, 23 to a circuit 21 in which they are combined subtractively with the video frequency signal due to the overall filter transmission (selected by means of L.P. filter 16) to provide the green colour component signals of terminal 30. By constructing the filter 6 so that one of component colours (in this case the green component which carries the largest proportion at the luminance content of the incident light) is continuously transmitted to the pick-up tube an improvement in sensitivity and signal-to-noise ratio is obtained. In a second embodiment (Fig. 3), the filter is divided into a repeating sequence 7a, 8a, 9a of sections of small angular extent the portions 7a, 10a and 12a transmitting green light and the portions 11aand 13a transmitting yellow and cyan light respectively. Since the portions 10a and 12a transmit green light the portions 7a may be omitted if desired and, additionally, the overall green transmitting portions may be replaced by filter sections transmitting light corresponding to the luminance component Y of the NTSC system. Alternatively, two camera tubes may be employed the first being continuously exposed to the green (or Y) components of the scene and the second provided with a filter disc having successive groups of two sections, the first section transmitting red uniformly and the second section transmitting red and magenta alternately. Instead of constructing the filters as rotating discs they may be formed by a moving endless loop of film or plastic tape. Specifications 787,331 and 852,506 are referred to.

Patent GB-651520-A (GB)
Title: Improvements in or relating to signalling systems
IPC: H03M1/00
Filed: 1948-01-16
Abstract: 651,520. Secret transmission. WESTERN ELECTRIC CO., Inc. Jan. 16, 1948, No. 1396. Convention date, June 19, 1946. [Class 40 (iv)] In a signal transmission system the instantaneous amplitude of a complex wave is continuously transmitted as a plurality of signal voltages of fixed magnitude each of which represents a different portion of the maximum signal amplitude and the portions are related in the binary scale. The signal from a microphone 10 after amplification in equipment 12 is applied to selective relays 14, 16 . . . 24, which unoperated have no output but in response to signals of more than a predetermined value produce at each of their output terminals a potential of that same predetermined value. The operating or output potentials of the selective relays 14-24 are related according to the binary scale and since the lower terminals of the relays 16-24 are connected to the output from the preceding relay the plurality of output potentials are always representative of the instantaneous signal amplitude. A diode 94, Fig. 2, is rendered conductive if the applied signal strength exceeds the opposing potential of a battery 98 so that the P.D. across the resistance 100 is increased and the anode potential of triode 104 is raised. The anode potential is limited to the required value (82 volts for relay 14) by diode 116 in conjunction with a battery 112 and is maintained at a predetermined potential (50 volts) in the absence of an operating signal by a diode 114 the anode of which is connected to a 50 volt tap on the battery 112. The selective relays 16, 18-24 function in an identical manner but the potentials of the incorporated batteries are different so that voltages of 16, 8, 4, 2 and 1 are produced. Since the voltage outputs 16, 8, &c. are relative to the outputs of the preceding stage it is necessary to incorporate a " digit grounder " circuit 26-36 in each relay which causes a predetermined voltage with respect to earth to appear at the output terminal of each operated relay irrespective of which of the preceding selective relays are functioning. The outputs from the associated relay 16 and the preceding relay 14 are connected to the grids of pentodes 136 and 138 respectively and the potentials with respect to earth of the upper ends of resistors 156 and 140 are averaged by a centre tap 50 of a high resistance potentiometer comprising resistor 148 and 162 to produce a potential of 8 volts at terminals 40. Potentials of 4, 2, 1, and ¢ volts are produced at terminals 42, 44, 46 and 48 respectively, by the operation of the relay, which may be transmitted by line or radio to D.C. amplifier limiters 50-60 each of which in response to a signal produces an output of 32 volts. Attenuators 64, 68-80, produce outputs related in the binary scale which are continuously added across load resistor 63 to reconstruct continuously the complex wave. Reference is made to the system described in Specification 630,094.
Patent GB-788003-A (GB)
Title: Variable multi-line printer
Filed: 1955-01-17
Abstract: 788,003. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 17. 1955 [Jan. 20, 1954], No. 1434/55. Class 100(4) Consists in the adaptation of a record controlled printing machine having a plurality of banks of print members in a single row to print addresses as described in Specification 743,628. and wherein the data for each address is contained in a single record card. so that addresses can be printed from data containing at least one main card and at least one separate address card. As described in Specification 743,628. the address strip S is fed diagonallv across the bank of print members so that when it comes successively in front of each of the groups of print members 1 to 4, it is elevated one line space. As shown, a tabulator as described in Specification 676,155, has record cards fed successively to two reading stations or sensing positions and makes use of four storage units A, B, C, D. Twelve cycles are shown for a set of cards some of which are single cards containing a three line address and some of which are two related cards containing combined the data for a four line address. As shown, in the first cycle the first line of a three-line address contained in a single card is sensed in the first read, and printed by print group 1, shown as A1, L1, and, in the next cycle, lines 2, 3 are sensed in the second read line 2, A1, L2, being printed direct by print group 2 and line 3, A1 L3, being stored in storage A or B for printing by print group 3 in the next cycle. The strip S is fed one print group space each time printing occurs so that line 2 is printed under line 1 which has moved from the first print group position. When a four line address with its data on two cards is encountered, as in cycle 3, line 1, A3 L1, is printed direct, as for a three line address. but in the next cycle the first card will be in the second, read position and printing in groups 1, 2 and the strip feed must be suppressed when this occurs to prevent re-printing of line 1 and subsequent misplacing of succeeding lines. Had the fourth line of an address been in storage and the next address been a three line one. a fourth line would have been printed by print group 4. The signal for the suppression of printing is derived from a "6" pulse derived from a perforation in column 1 of the second card sensed in the first read. The machine is stopped if a card is missing, if the multiple cards are reversed, or are in order but for different addresses, and for this purpose the usual total taking group control circuits are used in conjunction with a special perforation appearing in column 80 of the first address card. Specifications 605,132, 618,267, 672,339 and U.S.A. Specification 1,772,492 also are referred to.
