Title: Apparatus And Process For Stamping Tablets of Soap And The Like
Inventor: MOSES BERNARD CECIL
IPC: C11D13/28
Filed: 1965-10-07
Abstract: 1,152,466. Moulding soap. UNILEVER Ltd. 5 Oct., 1966 [7 Oct., 1965], No. 42649/65. Heading B5A. The grain structure of a soap tablet which is stamped to the capacity shape of a pair of opposed dies from a billet extruded from a soap plodder, is improved by placing a billet, which is oversize only in the direction of its longitudinal crystalline grain structure, between mating die halves to the contours of the ends whereof it is trimmed and then deformed and shaped between the die halves without extrusion therefrom. The billet is cut from a continuous extrusion and transferred by opposed grippers to overhang at its ends between a lower stationary die half 20 and an upper die half 19 mounted within a shell member 17 on a vertically movable slider 11 whereby, as the shell member 17 receives lower die 20 as a close sliding fit, the ends of the billet (Figs. 3-5, not shown) are trimmed by interaction of the rim 28 of the shell member 17 with the lip of the lower die half 20 and, during the subsequent closing together of dies 19 and 20, to within À001 inches of separation between their opposed lips, the billet is flattened, and deformed transversely to the capacity shape of the dies. The die half 19 is mounted for sliding movement with respect to the shell 17 via an upwardly spring loaded rod 23 rigidly connected by an arm 29 to an upper extension 30 on the exterior of slider 11 whereby, upon upward movement of slider 11 to open the dies 19, 20, the upward movement of extension 30 and of die 19 is prevented as a shoulder 34 on extension 30 is engaged by a detent block 42 on the end of a pivoted arm 38, spring loaded towards extension 30, and the shell 17 is displaced upwardly with respect to die 19; on continued upward movement of slider 11 the detent block 42 is displaced out of engagement with shoulder 34 as rod 38 is pivoted away from the slider by the movement of a cam roller 43 thereon along the raised portions of the profile 36, 37, 35 of a cam 31 attached to slider 11 whereby the die 19 is returned within shell 17 for further upward movement therewith and the moulded soap tablet remains on the lower die 20, under the action of a spring loaded ejection plunger 25 within die 19. The tablet is ejected from die 20 by a cam actuated ejector (not shown), upon tilting of die 20 by a rocker shaft. The inner surface of the shell 17 tapers slightly outwardly towards the rim to facilitate the escape of entrapped air during the moulding. In an alternative embodiment (Figs. 11 to 13, not shown) the upper die (47) is fixed to move with the shell (49) on the slider and the tablet is ejected only by a spring loaded ejector plunger (53); the ends of the shell (49) are provided with folded strips (60) of foam rubber which prevent the trimmed portions of the billet from tending to stick to the shell (49). Air escape passages (66, 57) may be provided in the upper die assembly. The die lips may also be curved to meet out of a plane.

Title: Method and machine for the production of jacquard patterned fabrics
IPC: D04B23/00
Filed: 1961-11-30
Abstract: 966,612. Warp knitted fabrics; knitting machines. K. LIEBRANDT. Nov. 30, 1961 [Jan. 11, 1961], No. 42817/61. Headings D1C and D1K. Warp knitted fabric is knitted by producing courses of interlinked threads and varying the interweaving pattern by the action on selected warp threads of a Jaquard motion which is driven at a rate less than the rate of production of the courses. The variation is achieved in a warp knitting machine by varying the number of needles 6, 7 underlapped by the threads 5 of the guides 8 of a guide bar which has a shogging stroke of uniform length. The variation is achieved by selectively raising the bar, by means of the Jaquard motion, to raise the guide to a position 8<SP>1</SP> where the thread in position 5<SP>1</SP> underlaps fewer needles. The Specification describes a number of patterns achieved by the method.

Abstract: 1,005,564. Transistor bi-stable circuits. ENGLISH ELECTRIC CO. Ltd. Dec. 11, 1961 [Dec. 14, 1960], No. 42952/60. Heading H3T. [Also in Division H2] A control circuit for providing control pulses for a converter has a plurality of bi-stable switching arrangements connected as a ring counter and driven by differentiated pulses. The circuit shown in Fig. 1 comprises a variable phase pulse source and the assembly 9 in which three bi-stable circuits each having transistors 10 and 11 control another transistor 12 which switches D.C. in the primary of the output transformer 13. The bi-stable circuits are arranged so that when one is switched by its appropriate pulse source, it restores to its previous state the bi-stable circuit which was switched just before the one in question. The star-connected three-phase supply 17 has a variable D.C. bias applied to its neutral point and is clipped by reverse parallel connected germanium diodes 3, 4, giving approximately a square waveform, the positive and negative portions having, in general, different durations. The capacitor 7, resistor 6 and rectifier 8 pass only a pulse, and the waveform changes from negative to positive. Variation of the D.C. bias permits a phase displacement of about 160 degrees (from about 10 degrees after the negative peak to 10 degrees before the positive peak). The output of S.C.R.'s controlled from the transformer 13 is proportional to the D.C. bias voltage. In the arrangement of Fig. 2 (not shown) an oscillator is used.

Title: Method of producing a tobacco filler stream
IPC: A24C5/39
Filed: 1965-10-13
Abstract: 1,115,357. Feeding tobacco. K. KÍRBER. 13 Oct., 1965 [1 Dec., 1964], No.43387/65. Heading A2C. A uniform tobacco filler stream is produced by combining a uniform stream of cut tobacco foil material with a uniform stream of cut natural leaf tobacco immediately prior to producing a smokable article. A tobacco conveyer belt 52 (Fig. 1) is guided over a roll 54 driven from a motor 81 via a gear box 80. A cigarette paper strip 79 is withdrawn at the same speed as the belt 52 from a reel 78 and has deposited thereon a rod 73 of artificially produced tobacco foil from a rotating funnel 55. The tobacco foil is drawn from a reel 67 and passes through cutters 61 and 62 which cut the strip before it enters the funnel. The reel 67 and funnel 55 are driven by suitable driving elements from the gear box 80. A constant amount of tobacco foil is thus deposited on the paper 79 per unit of time. Cut natural tobacco 4 (Fig. 2) is delivered by rollers 5, 6 and 16, driven by motor 15, to a weighing container 8 which is attached to one end of a weighbeam 9. Movement of the weighbeam 9 controls contacts 12 and 13 which de-energize motor 15 as soon as an amount of tobacco corresponding to a weight 11 has been fed to the container 8, surplus tobacco being retained in a fixed hopper 28 provided with stop means 32. A flap 17 is provided on the container 8 which is periodically opened under the control of a device 48 at equal time intervals, the device 48 being controlled by contacts 112 which are operated by a cam 111 driven from the gear box 80, to assure that there are no fluctuations between the relative rate of delivery of the natural and foil tobacco. The weighed portions of natural tobacco are deposited on to a slide path 19 and pushed by a pusher 22, reciprocating in timed relationship with the opening of the flap 17, between conveyers 20 and 35 to form a uniform fleece. This fleece is taken by a drum 35 and thrown by a roller 42 on to a conveyer 39 from whence it is delivered over the plate 47 to the cigarette paper 79. The drive for the various tobacco conveyers means is derived from the gear box 80. Instead of the apparatus shown in Fig. 1, apparatus similar to that shown in Fig. 2 may be used for delivering the tobacco foil to the cigarette paper, Figs. 4a and 4b (not shown).

Abstract: 956,728. Waveguides. VARIAN ASSOCIATES. Dec. 28, 1960 [Dec. 28, 1959; June 27, 1960], No. 44478/60. Heading H1W. [Also in Divisions H3 and H4] An arrangement providing the equivalent of a hybrid junction in a power divider, mixer, parametric amplifier &c., comprises a waveguide arranged to support two orthogonal modes, the electric fields of which are asymmetrical about all equipotentials of one mode but symmetrical about an equipotential of the other mode. Vertically and horizontally polarized modes propagating in a square waveguide (see Fig. 1a) provide the required fields when one of the modes is perturbed by an obstacle e.g. a post 11. Both modes are symmetrical about the equipotential e-e of the vertically polarized mode but are not symmetrical about any equipotential of the horizontally polarized mode. The amplitudes of the fields in the regions of the arrows represent respectively the sum and difference of the amplitudes of the orthogonal fields. Means responsive to these sum and difference fields, e.g. rectifiers or waveguide terminals, are coupled to these regions. Perturbation may be caused by localized attenuation or intensification of the field using e.g. an attenuating card 12, Fig. 1b or a small deformation 13 of the wall of the guide. In the Doppler radar duplexer of Fig. 11, a horizontally polarized transmitted wave is perturbed by a deformation 107 of the wall of a circular waveguide 92 whereby a small fraction of the transmitted energy is coupled to a pair of diodes 95 extending along vertical radii between an axial conductive cylinder 98 and the wall of the guide. The received wave is vertically polarized and couples directly with the diodes. The duplexer shown includes a quarter-wavelength phase-shifter 102 for converting between plane-polarized waves and circularly-polarized waves radiated by an antenna 106. If the radiated energy is to be plane polarized, a 45 degrees Faraday rotator is used instead of a phase-shifter.
