IPC: B65D30/24
Filed: 1969-10-02
Abstract: 1292038 Bags INDUSTRIELE ONDERNEMING WAVIN N V 2 Oct 1969 [10 Oct 1968 2 April 1969] 48473/69 Heading B8K A plastics bag is made from a flattened tubular blank 1 by forming a first corner flap 11 between a longitudinal edge 3 of the blank and an incision 8 made from one end of the blank, bottom flaps 14a, 14b being formed from the incision 8 towards the other longitudinal edge 2, the bottom edges 6, 7 of the bottom flaps being inclined relative to the longitudinal edges 2, 3 and a second corner flap 21 being formed by folding triangular portions of the bottom flaps adjacent the other longitudinal edge, inwardly towards that edge. As shown, the blank is folded about lines 10, 13 and the bottom flaps 14a, 14b and the triangular face 12 formed thereby are folded about lines 13a, 13b. The flaps 14a, 14b are then folded back and a triangle 12a defined by lines 15, 17, 20 is folded under the remainder of the face 19 to bring a triangle 12b beneath triangle 12a. The same procedure is followed with triangles 12c and 12d, whereafter the flaps 14a, 14b are folded over one another and sealed as shown, either discontinuously or continuously, and with or without the interposition of plastics foam 24. In another arrangement, Fig. 4 (not shown), the triangles 12a, 12c are folded back on to the remainder of flap 21. In another arrangement, Figs. 5-8 (not shown), an additional incision is made adjacent the side edge 2. In a further arrangement, Figs. 9-11 (not shown), comprising two incisions in the blank, the inclined end edges extend only between the incisions, and the inner portion of the flap 11 is provided with superficial incisions to improve flexibility of the flap and to facilitate the valve action of the flap. The superficial incisions are formed by a toothed clamping member (39)- (41), Fig. 13 (not shown), and sealed joints are obtained by means of a sealing member (44), Fig. 14 (not shown).

Title: Improvements in matrix memory systems comprising magnetic cores
IPC: G11C11/06
Filed: 1966-10-28
Abstract: 1,114,339. Magnetic memory matrices. SOCIETE INDUSTRIELLE BULL-GENERAL ELECTRIC. 28 Oct., 1966 [6 Nov., 1965], No. 48572/66. Heading H3B. A memory plane in a three-dimensional matrix includes magnetic cores 11 arranged in rows and columns and is divided into four square sections SG, SD, IG, ID, X and Y windings (not shown) and four inhibit (Z) windings (not shown) being provided, together with four sense windings 12 (only one shown) threaded in bifilar fashion through half the cores in two diagonally opposed sections, and following different diagonal directions in the two sections. The second bifilar sense winding for sections SG and ID is threaded through the remaining cores of these two sections, lying at right angles to the first sense winding 12 in both sections. Two further sense windings are similarly threaded through sections IG and SD. Terminals 13A, 13D are connected to a differential amplifier. The terminals may be on different sides of the memory plane, as shown, or may be on the same side if the outward and return portions of the winding extend in the same direction. Since a sense winding passes through only half of the half-selected cores in a section when a core is interrogated, noise is reduced. Instead of connecting the outward and return conductors in series the points 16A, 16R may be earthed through the characteristic impedances of the lines. The inhibit windings are single conductors passing through all the cores of a row in two adjacent sections and returning through the cores in the next row. In one arrangement this pattern is repeated in the next two rows. Each inhibit winding extends through half the rows in an adjacent pair of sections (Fig. 3, not shown). In a second embodiment the pattern is repeated in every second pair of rows, a further inhibit winding being similarly arranged in the intermediate pairs of rows. In the final embodiment the pattern is repeated in every fourth pair of rows. In a matrix the inhibit windings in adjacent planes lie parallel to the rows and parallel to the columns, respectively.

Title: Data processing systems
IPC: G06F11/07
Filed: 1973-10-19
Abstract: 1442665 Data processing system SIEMENS AG 19 Oct 1973 [14 Dec 1972] 48806/73 Heading G4A In a data processing system in which processing is performed in a series of operating cycles under the control of control signals, the various control signals generated in successive operating cycles are recorded in a tracing device for subsequent transfer, together with the contents of various registers, to the store of the system, e.g. for subsequent diagnostic operations in which the recorded control signals are compared with the expected signals. The system comprises several processors each of which includes a control section ST generating control signals on respective lines StL1- StLm, a register section RT including input registers, output registers, program counter registers &c., and a tracing section PS which as described includes shift registers PSE1-PSEm. The processor operates in a series of sequences defined by a fixed or variable number of clock pulses t1-t8. At each clock pulse the control signals formed E are recorded in respective ones of the shift registers. so that at the end of a sequence a complete record of the control signals formed is avaiable for transfer to the main store (not shown) for analysis in a diagnostic routine. Where the sequences contain a variable number of clock pulses the recording of the control signals continues until a counter preset with the number of pulses in a sequence has been counted down to zero by the clock pulses. In order to reduce the amount of tracing storage required groups of necessarily mutually exclusive control signals, or groups of necessarily coincident control signals may be recorded in a single shift register. It is stated that tracing may be performed during special diagnostic sequences performed on the processors, the recorded control signals being systematically transferred to the main store, or during normal operation in order to maintain a record for use when a sudden fault occurs, the recorded control signals being transferred when a fault occurs. The contents of the tracing unit may be read into the store after each sequence of, e.g. 8, clock pulses, it being stated that each program may be divided into such sequences and a program may be interrupted by a higher priority program at the end of a sequence.

Title: Determination of oxygen consumed in the stabilisation of organic material
IPC: C02F3/00
Filed: 1965-11-17
Abstract: 1,132,456. Microbiological determination of oxygen. WALLACE & TIERNAN Inc. Nov.17, 1965 [Nov.17, 1964], No.48901/65. Heading C6F. The oxygen consumed in the stabilization of organic matter, e.g. sewage, effluents, is determined by establishing a mixture of a culture of micro-organisms and the organic material for effecting rapid stabilization of the organic material in the mixture, providing the mixture with a sufficient supply of oxygen to ensure rapid stabilization, and detecting the contemporaneous rate of oxygen consumption in the mixture at a time during the rapid stabilization. The determinations may be made with the aid of the oxygen uptake rate device set forth in Specification 1,132, 457 represented here by 46 on Fig. 10. The culture of micro-organisms or, for the determinations, the culture with added organic material is pumped by a pump 50 through an assembly 48 consisting of inlet and outlet probes providing electrical signals representative of the content of dissolved oxygen. The device 46, pump 50 and a rotary aerator 86 are mounted on a support 56, the height of which is adjustable by rotation of a screw 62. One typical example is directed to the determination of fish food from a pet shop. 500 mg of the fish food was mixed with each litre of a culture containing roughly 3, 490 mg of micro-organisms that had previously been grown on a portion of the fish food, and the oxygen uptake rate of the mixture was determined at successive times until a steady state value, representing auto-oxidation, was reached. The rates of oxygen consumption over the. period (typically half an hour) of the biological oxidation (stabilization) of the organic material were plotted on a graph of the form shown in Fig. 1 and the total oxygen consumption for stabilizing the mixture, as given by the area 33 above the base line 22 - 30 was computed to be 53.7 mg oxygen per litre of the mixture of feed material and culture. For the concentration of feed material employed, this amount of oxygen corresponded to an energy oxygen of 0À1075 mg of oxygen per mg of fish food. Other organic materials mentioned are sucrose, acetic acid and monoethanolamine acetate. The testing can be repeated e. g. at intervals of an hour or two.

Title: Control Arrangements for the Power Stabilisation of Metal Vapour Discharge Lamps.
IPC: H05B41/392
Filed: 1967-10-27
Abstract: 1,167,920. Supply systems for gas-discharge lamps. NOVELECTRIC A.G. 27 Oct., 1967 [27 Oct., 1966], No. 48983/67. Heading H2H. [Also in Division G3] In a lamp control circuit the power consumption of the lamp is controlled in dependence upon a signal which is generated as a function of the sum of lamp voltage and lamp current rather than as the product thereof. As shown, a high pressure discharge lamp 10 is supplied from an AC. input O, P by way of a choke D, a resistor R and back-to-back thyristors 12. A first signal, representative of lamp current and derived from resistor R, and a second signal, representative of the voltage across the lamp 10, are respectively applied to the primary windings of transformers T1, T2 the secondary windings of which are series connected to produce a resultant signal corresponding to the sum of the first and second signals. This resultant signal is compared in a controller 14 with a reference signal derived from a source 16, and the thyristors 12 are controlled by the output from controller 14 so that the power consumption of the lamp is maintained approximately constant. The Specification states that the use of such a resultant signal gives a sufficiently accurate control and yet allows the circuitry to be much simpler than that required to produce a true power-representarive signal, i.e. one derived by multiplying lamp current by lamp voltage. Thyratrons or a triac may replace the thyristors 12. In another embodiment (Fig. 2, not shown) the choke D and the lamp 10 are arranged in a bridge circuit with two resistors, and the required resultant signal for application to rhe conrroller 14 is derived from a transformer connected across one diagonal of the bridge.

Title: Two-wire to four-wire conversion circuit for a data switching centre
IPC: H04Q3/52
Filed: 1970-10-16
Abstract: 1,268,038. Two to four wire converter; automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 16 Oct., 1970 [17 Oct., 1969], No. 49306/70. Headings H4K and H4R. A 2/4 wire converter is provided by a hybrid transformer T having a primary winding which is connected to line and a secondary winding which has twice as many turns as the primary. The secondary also has its centre tap connected via a resistance R1 to a reference potential and its outer ends connected respectively to Go and Return amplifiers GN, Gm, the latter both functioning as current amplifiers and having very low input impedances and very high output impedances relative to R1. In the embodiment, the amplifiers are bipolar transistors in common base configuration. The latter's very low reverse voltage transfer ratio prevents signals incoming from line from being applied to the microphone K even though most of the incoming voltage is developed across the high impedance output Rs of Go amplifier GN. In respect of outgoing signals it is demonstrated mathematically that no signal at all appears across the input of the Return amplifier Gm (this being irrespective of the impedance ZK of the microphone). The arrangement may be modified by breaking the secondary at its midpoint, interconnecting the broken ends by a capacitor and connecting each side of the capacitor to the reference potential via a resistor having twice the resistance of the single resistor R1. This embodiment is used in a subscriber line circuit in an exchange employing 4-wire switching and utilizing MOSTs as the crosspoint devices (Fig. 2, not shown) for example as in Specifications 1,261,599 and 1,199,119.

Title: Manufacture of film webs having selected oriented portions
IPC: B29C48/91
Filed: 1969-10-08
Abstract: 1,245,842. Film webs having selected oriented portions. FMC CORP. 8 Oct., 1969 [17 Dec., 1968], No. 49404/69. Heading B5B. A film of thermoplastic polymeric material having a predetermined pattern of molecularly oriented portions is made by melt extruding a flat unbroken stream 17 (Fig. 1) of the material through a slot die 15, receiving the molten stream upon a chill roller 19 provided with a series of circumferential and longitudinal grooves 21 and 23 (Fig. 2) which intersect each other, leaving selected projecting surface areas 25. The grooves 21 and 23 are equally spaced in their respective directions and thus the surface areas 25 are of like size and aligned both circumferentially and longitudinally of the roller 19, which is driven in the direction indicated by the arrow 27. The stream 17 of molten thermoplastic material is cooled to provide a solidified integral film web 29 which is still hot when stripped from the roller 19 by the roll 33 but can be further processed without distortion. When advancing over the roller 19 the molten film 17 snugly contacts the selected roller surface areas 25 while spanning the roller grooves 21 and 23, whereby the portions of the molten film 17 which contact the areas 25 are cooled more rapidly than the portions adjacent thereto. The web 29 removed from the surface of the chill roll 19 by the stripping roll 33 is passed successively between a pair of driven nip rolls 35 and a pair of nip rolls 37 driven at a higher peripheral speed than the rolls 35 whereby sections 39 (Figs. 3 and 4) of the web which extend transversely of the web at longitudinally spaced intervals thereof are stretched longitudinally to orient the molecules thereof. Since the selected web areas 31 had been cooled to a lower temperature than the surrounding region of the web when the latter was travelling over the chill roller 19, these areas do not yield under the longitudinal stretching force and thus prevent longitudinal stretching of the regions between the adjacent transversely aligned areas 31. On leaving the nip rolls 37 the web 29 is passed through a conventional tenter frame 41 wherein sections 47 of the web 29 (Fig. 5) are stretched transversely to orient the molecules thereof while the cool selected areas 31 do not yield during this stretching stage and thus prevent drawing of the regions of the web located between the adjacent longitudinally aligned areas 31. The remaining regions 55 of the web 29 (Fig. 5) have been biaxially stretched. The chill roller may have-depressions of like circular and concave shape aligned longitudinally and circumferentially of the roller surface and equally spaced in these directions, whereby the cooler selected areas are circular instead of square in shape. The film web may be stretched to produce fibrillation along the biaxially oriented areas thereof.
