Title: A bag with reinforced mouth portions and a process of making the same
IPC: B31B19/86
Filed: 1960-03-18
Abstract: 913,082. Making paper bags. EQUITABLE PAPER BAG CO. Inc. March 18, 1960 [April 14, 1959], No. 9635/60. Class 94(2).  In a known method of making shopping bags with handles wherein reinforcing patches are applied to a paper web which is thenformed 'into a tube and cut into bag lengths, transverse cuts are made across those locations only of the width of the web where the handles are to be applied and are spaced lengthwise by a bag-length distance, their lengths being within the limits of a reinforcing patch, and handles are applied extending across and within the transverse limits of the cuts, the severing into bag lengths being carried out as continuations of the transverse cuts. The paper web W is drawn off a supply roll 1 and is perforated between rotary elements 2 to form openings 3, Fig. 2, for the cords of bag handles, and the final severance, after the web has been formed into a tube in the zone T, is performed by rotary cutters 4 which are designed to provide clearance for the bag handles while complementing the perforations 3, already made. Patches 12 are applied to the web at intervals such that, when the cutting operations are performed at 2 and 4, the patches span the lines of severence. The patches are cut from a web PW, by rotary cutters 16, and applied by a roller 13, patches of paste 11 of appropriate shape having been printed on the web W by a roller 6. Means for applying the patches which attach the cords of the bag handles to the web are indicated at 19, the handles being formed and applied by mechanism indicated at 18. The adhesive applying means for the handle patches is generally indicated at 20 and the roller for applying the line of adhesive for the bag tubing is shown at 21. Forwarding rollers 5, operating at a slightly higher peripheral speed than the linear speed of the tube, separate the cut bag lengths and forward them for further processing. The width of the patches may be increased to provide entire reinforcement for the bag bottoms. Parallel," continuous strips of reinforcing material may be applied, the cutters then being opened so as not to out the material, and a continuous suspension saddle for the bag handles will then be formed. In another modification, continuous reinforcing material may be provided for the side walls of the bag.

Abstract: 999,607. Pulse shaping, gating and clipping circuits; television. REDIFFUSION TELEVISION Ltd. June 14, 1962 [March 16, 1961], No. 9655/61. Headings H3P, H3W and H4F. The rise or fall time of an electrical waveform is reduced by first increasing the high frequency components so as to provide a wave with overshoots and clipping off the overshoots with the aid of two reference waves which are produced from the initial waveform and which have rising or falling parts which straddle in time the rising or falling part of the waveform. The invention may be applied to conventional or slow-soan television or to film telerecording or scanning standard conversion equipment or to radar or facsimile equipment. Figs. 1 and 2 show a system for improving the definition of television pictures. Consider a video step wave such as AGHDZ at the input line 4. The high frequencies are increased by amplification at 7 and the resulting waveform delayed by a real or artificial line 10 giving waveform ABOEZ. The delay 10 may be inherent in an amplifier at 7. The input waveform AGHDZ is also delayed at 11 giving pairs of reference waveforms AGHDZ and ACKJZ which are used to control gating diodes 21-27 so as to clip off the overshoots 8, 9. The diodes are biased from negative and positive sources via resistors R, R<SP>1</SP> so that diodes 21, 25 are conductive between times G and J for positive-going steps and 22, 26 conductive during corresponding times for negative-going steps. Diodes 27, 23 respectively clip off the overshoots 8, 9 hence the waveform ACODZ having a reduced rise time appears at the output. The D.C. component may be blocked by a capacitor in series with resistor r, diodes 23, 27 acting as D.C. restorers. The low frequency components of the waveform may be filtered out before it is applied to the circuit shown. The clipping action can be improved by the use of a further delay line 41 and two further diodes 42, 43.

Title: Improvements in or relating to electromagnetic wave transmission systems
IPC: H01P1/163
Filed: 1959-03-20
Abstract: 855,723. Waveguide couplers. WESTERN ELECTRIC CO. Inc. March 20, 1959 [March 28, 1958], No. 9703/59. Class 40(8). A wave energy distribution system comprises two circular waveguides arranged coaxially one within the other, the larger of the two guides being dimensioned to support a second order mode having an electric field null which coincides with the boundary of the smaller guide. In the directional coupler shown, the inner guide is divided into two sections 11, 12 by a gap d, both sections being dimensioned to support only the H 01  mode at the operating frequency. The outer guide 13 is dimensioned to be just below cut-off for the H 03  mode at the operating frequency so that H 01  mode energy propagating from left to right in the guide 11-will excite both the H 01  and the H 02  modes in the gap d. These modes propagate with unequal phase constants #1, #2, so that if the length of the gap d is such that (# 1 -# 2 )d = (2n-1)# the two modes suffer a differential phase change of 180 degrees. At the end of the guide 12 the field configuration is such that the electric vectors of the two modes are in antiphase within the area defined by the guide 12 and in phase within the area defined by the annular gap 2. Thus the whole of the energy is transferred to the annular gap within which it is propagated in a coaxial mode. By means of the known type of converter shown, this mode may be transformed to the dominant H 01  mode within a rectangular guide 16. Any ratio of power division between the coaxial guide 2 and the inner guide 12 may be achieved by suitably dimensioning the gap d. Thus an equal division of energy is obtained by making (# 1- # 2 )d =(2n-1)<SP>#</SP>/ 2 . The coaxial guide 2 is matched to the H 02  mode by making the boundary of the guide 12 co-incide with the electric field null of this mode. It is stated that reflection of H 01  mode energy from the end of the guide 12 is negligible. Mode converters of the kind shown may be provided at both ends of the coupler. Specification 855,026 and U.S.A. Specification 2,748,350 are referred to.

Title: Step by step drive mechanism
IPC: D06F39/00
Filed: 1966-03-07
Abstract: 1,120,167. Escapements. W. HOLZER. 7 March, 1966 [8 April, 1965], No. 9775/66. Heading F2X. An escapement, which may be used in a washing machine, has a continuously windable spring force storage means 3, a stepping mechanism 5 and a coil-spring clutch 12 acting on the stepping mechanism under control of the storage means 3. The clutch consists of a coil spring wound around separate coaxial shafts 9, 10 and having its upper end free while its lower end is anchored to a control disc 8 driven through gearing from a motor 2 which also winds the spring storage means 3 through gearing. The movement of the stepping mechanism 5 is released after every half or full revolution of the spring storage means 3 by an escapement 6. Initially, the shaft 10 drives the shaft 9 by friction until the speed of the latter shaft falls sufficiently to unwind the spring 12 when the drive is disengaged. Rotation of the disc 8 eventually tightens the spring to re-engage the drive and the process is continuously repeated. In a further embodiment, the clutch 12 is replaced by a lever escapement spring-loaded into engagement with a constantly driven eccentric and having claws to engage teeth on the periphery of the stepping mechanism. The latter may also be directly driven from the spring storage means and be connected by feedback gearing to an over-ride clutch in the drive from the motor to the spring means.

Abstract: 807,416. Solid fuel furnaces; baffles. STAMICARBON N.V. March 26, 1957 [March 28, 1956], No. 9886/57. Class 51 (1). In a solid fuel furnace, secondary air is discharged across the secondary combustion chamber along a path shielded from the direct flow of the combustion gases by a baffle in the flowpath of the gases and of such shape as to cause the gases to eddy into the path of the secondary air. In one embodiment, Fig. 1, a baffle 7 extends the full width of the secondary combustion chamber 6 in a plane at right angles to the direction of flow of the combustion gases. Secondary air from an inlet 8 in the side wall of the chamber 6 flows across the chamber behind the baffle 7, and is entrained by the eddies of combustion gases. Air may be supplied at both sides of the combustion chamber, and the baffle plate 7 may be flat or curved, or may be replaced by two plates set at an angle to each other. If two baffles are used, air may be supplied through two inlets, one shielded by each baffle. In a furnace of the type having a rear grate of vertical tubes 9 between the primary and secondary combustion chambers, flat baffles 12 are secured to the rear of each tube 9, and air from a tube 10 fitted to the wall of the bunker is discharged downwardly. A pipe 10 may be fitted half-way down the tubes 9 to discharge air upwardly and downwardly. Specification 698,098 is referred to.

Abstract: 1461070 Desulphurizing Claus off-gases SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 27 Feb 1974 [1 March 1973] 9931/73 Addition to 1356289 Heading C1A In a process for reducing the sulphur content of Claus off-gases by passing in admixture with H 2  and/or CO over a sulphided metal catalyst at >175‹C., and. then passing into a liquid, regenerable H 2 S absorbent, the H 2 S content of the spent absorbent is increased prior to its regeneration and the recovery of the H 2 S, by contacting it with a stream containing H 2 S at a higher partial pressure than that of the reduced Claus off-gases. In the figure, spent absorbent from absorption column 6 is passed through line 11 to a second absorption column (23) where its H 2 S content is increased by contact with an H 2 S feed stream (24). The H 2 S enriched absorbent is passed via line 26 to the desorption column (13) for regeneration, the H 2 S liberated passing via line 17 to a cooler (18) (to condense all the water vapour present) and from thence to a Claus plant (20). The regenerated absorbent is passed via line 15 through a heat exchanger (12), a cooler (16) and is then divided at A between two streams (15 and 22) going respectively to the absorption columns 6 and 23. The reduction of the Claus off-gases occurs in reactor 3, in the embodiment figured, at 225‹ C. The hydrogen required for this reduction can be supplied to the catalyst bed separately or may be added direct to the Claus off-gases in the line 1. After passing through heat exchanger 5 the cooled reduced Claus off-gases enter absorption column 6 where H 2 S is absorbed.
