Dec. 12, 1933, No. 34948. [Classes 125 (ii) and 125 (iii)] A bottle-capping machine comprises a cap forming die which forms the central portion of a cap blank over the head of a bottle and bends the remaining portion of the blank downwardly about the neck of the bottle to form a skirt, mechanism for wrapping the skirt about the neck of the bottle, and stapling means for securing the skirt in the wrapped position. Fig. 25 shows a perspective view of a completed cap A on a bottle B. The machine comprises one or more cam operated reciprocating bottle rests 11 having rotatably mounted seats 14. Cap-blanks a are fed from a stacker M supported on a frame 7 which can be adjusted in height to suit the various heights of bottles to be capped. Conical guides 44 align the bottles and their superposed blanks, with the cap forming dies, as the bottles are raised on the rests 11. The cap forming dies comprise upper and lower relatively rotatable plates 47, 49 with intermediate cam and gear rings 48. Rotatably mounted platens 50 hold the caps on the bottle mouths during the plaiting and stapling operations. The plait folding mechanism Fig. 21, comprises three slides 59 radially movable in grooves 56 in the ring 47, having upwardly projecting studs 59<1> which engage in cam grooves 60, (Fig. 3) in the plate 48. The cap skirt is plaited by the upward movement of the cap through radial slots 55 in the plate 47, causing plaits a<1> therein. Each slide 59 carries a pair of levers 61, 61<1> and these levers engage adjacent plaits a<1> and fold them in opposite directions against the neck of the bottle. Each stapling device comprises a horizontal slide 89 movable radially of the rings 47, 48 along suitable guides 90, and a staple clinching slide 91. The wire forming the staples is fed from reels and cut and bent by the stapling mechanism before it is forced through the overlapping plaits a<1> in the bottle-cap. The plaits are successively stapled in three operations on partial rotation of the bottle.

Title: Improvements in or relating to the production of alcohol by fermentation
Inventor: BEACH ALAN STEPHEN
IPC: C12P7/06
Filed: 1954-12-04
Abstract: Alcohol is produced by fermenting whey under conditions of aeration with Candida pseudo-tropicalis XI.  The cultural characteristics of this micro-organism are described, the strain XI differing from the usual strains in its ability to use arabinose as the sole source of carbon and in its capacity for producing ethanol rapidly and in substantial quantities from lactose.  The whey is from fresh milk or from reconstituted dried milk or skimmed milk.  Other fermentable carbohydrates and nutrient salts may be added to the whey.  The fermentation medium is adjusted to pH 4-8.  Fermentation is at 20-35 DEG  C.  Examples are concerned with fermenting a 5 per cent lactose rennet whey from cheese manufacture preliminarily adjusted to pH 4.5 by hydrochloric acid and boiled to precipitate proteins and fermenting a 5 per cent lactose whey from acid casein manufacture preliminarily adjusted to pH 6.5 by sodium hydroxide and boiled to precipitate proteins.

Title: Improvements in and relating to the control of selectivity in radio receivers
IPC: H03G5/20
Filed: 1938-12-03
Abstract: 522,258. Radio receiving circuits. MURPHY RADIO, Ltd., and MOXON, L. A. Dec. 3, 1938, No. 35304. [Class 40 (v)] Improved fidelity or selectivity with given selectivity or fidelity is obtained by dividing the received signal at carrier frequency, e.g., from the intermediate frequency amplifier 1, into a broad band fed to a detector 5 and a narrow band fed to a detector 2. The output of detector 2 passes through a low-pass filter 9 and that from detector 5 through a complementary high-pass filter 11, the outputs are either associated at a low frequency amplifier 6 or applied to separate loud speakers. Selectivity is adjusted by control of the high-pass filter or by a tone control network. It may also be adjusted automatically by a valve arranged to serve as a capacity and controlled by a bias derived from the wanted carrier, the unwanted interference or the ratio of these.

Title: Improved method and apparatus for applying tension to work-pieces produced on a flatbed fully-fashioned rib knitting machines
IPC: D04B15/90
Filed: 1963-09-06
Abstract: 1,014,623. Knitting-machines. S. A. MONK (SUTTON-IN-ASHFIELD) Ltd and B. A. MONK. Aug. 27, 1964 [Sept. 6, 1963], No. 35318/63. Heading D1C. Fabric take-down mechanism for a flat parallel bed machine comprises feeding a wire 52 to a position adjacent the needles after the needles of both beds have drawn the first course, and then causing hooks 20 which have been projected up between the needle beds to be lowered so that they grip the wire and draw it downwards into engagement with the loop structure so as to impose a tension on the first and subsequent courses as they are knitted. The machine may be a multidivision full fashioning machine and the wire 52 for each division is held magnetically by arms 50 coupled to a linkwork 48 which after the needles have drawn the initial course are operated to position the wire adjacent the needles, Fig. 2(a). In the meantime a series of hooks 20 mounted in a bar 19 attached by lugs 18.to brackets 27 are raised to pass between the beds so that the hooks are in a position to engage the wire. The hooks are raised by the brackets being coupled through a cable 17 to a drum 16 through an electro-magnetically operated clutch 24 from a shaft 10. The clutch is operated to cause the hooks to rise and fall to engage the wire, the control of the clutch being such that as the knitting progresses and the width of the fabric varies the tension imposed also is varied. After a predetermined length of fabric has been produced a number of levers 29 pivoted on a shaft 26, secured to the end brackets 27, engage by means of a weighted roller 30, on one arm of the lever, a camming member 33 whereby the lever is tilted and its other arm carrying a friction pad 31 is withdrawn from contact with a bar 25 also secured to end bracket 27. A pedal operated link 45 is then actuated to pivot an arm 35 and cause an upstanding rod thereon to deflect a latch 28 securing lug 18 to bracket 27 at each end of each division of the machine. The clutch 24 is then energized to cause the bracket 27 to rise with the bar 25, shaft 26 and levers 29 such that the fabric which continues to be tensioned by the hooks 20 and bar 19 extends down between the lever 29 and bar 25. If further tensioning is required, the clutch 24 is de-energized and the brackets allowed to descend whereupon the levers 29 under the influence of their weight rollers 30 cause the friction pads 31 to press the fabric against the bar 25 thereby gripping the fabric therebetween. The brackets 27, levers 29 and bar 25 proceed to descend under the control of the magnetic clutch 24 whereby the fabric tension can be varied in like manner to that when the fabric was being withdrawn under the influence of hooks 20. In a multidivision machine there is one clutch 24 for each division, the clutches being collectively operated but capable of individual adjustment.

Title: Torsion bars
IPC: F16F1/14
Filed: 1953-12-19
Abstract: 748,587. Torsion bars. AUSTIN MOTOR CO., Ltd., and HARNOTT, J. R. Dec. 17, 1954 [Dec. 19, 1953], No. 35403/53. Class 108 (3). In a laminated torsion bar, the laminations are afforded by a number of tubes 10, 11, 12, which are nested one within another with full-area contact between their mutually confronting surfaces, and are all locked together against relative rotation at one end. As shown, each tube is divided diametrically into two half tubes, the joints between the latter being staggered by 90 degrees from the corresponding joints in each adjacent tube. The tubes are held together by clamps 18, the screws 19 of which may be suitably adjusted to control the friction between the tubes. The friction may also be produced by radially or axially distorting the inner tube, or by contracting the outer tube. The tubes are maintained in register by a key-piece 17 which engages slots 16 in the ends of the tubes, slots 21 in split clamping members 20, and a slot 23 in a plug 22. The key-piece 17 and the plug 22 may however be unitary. The tubes 10, 11 and 12, may be solid drawn, instead of being in two parts. Each tube may be treated so as to have a stressed-skin condition.

Title: Ultrasonic penetrant methods of flaw detection
IPC: G01N29/04
Filed: 1955-12-09
Abstract: 785,775. Testing physical qualities of materials. SWITZER BROS., Inc. Dec. 9, 1955 [July 27, 1955], No. 35437/55. Class 106 (2). [Also in Group XXXVIII] The method of testing for flaws having surface openings in parts such as forged aluminium fittings, iron castings, ball-bearing races, &c., by applying a penetrant liquid to the surface of the body under test and after superficial removal of the penetrant inspecting the body for the appearance of penetrant which was retained in the flaw, is expedited by the application of ultrasonic vibrations to the body at a frequency to which the body is resonant. The vibrations may be applied at the first stage to assist penetration and/or at the inspection stage to assist in expelling the penetrant. For example, the normal time of immersion in a penetrant may be reduced from 15 minutes to a matter of 10 seconds when vibrations are applied; or a period of ¥ hour standing after drying to allow indications to appear may be accelerated to give full development after 30 seconds of vibration. The frequencies are usually in the range 10 kc/s. to 500 kc/s., but higher or lower frequencies may be used. Piezo-electric transducers are recommended for determining resonant frequencies of articles to be tested, but the more rugged magneto-strictive type are preferred for production testing of mass produced articles whose resonant frequencies are usually below 50 kc/s. If the bodies to be tested are themselves magneto-strictive they may be passed, while immersed in penetrant, through a coil carrying pulses (for example, 30 per second) of current alternating at the resonant frequency of the bodies. Known methods of detecting the penetrant exuding from flaws are utilized, for example, a fluorescent dye may be dissolved in the penetrant liquid, or a finely dispersed pigment may be used. The process may be applied to articles having different resonant frequencies in different portions by transducing the appropriate frequencies in the different parts taking care to avoid fracture in the boundary zones. Specification 684,021 and U.S.A. Specifications 2,259,400 and 2,405,078 are referred to.

Title: Improvements relating to the production of rubber tape
Inventor: NEWNHAM JOHN LEATHEM MATTHEW
IPC: B32B37/00
Filed: 1959-10-20
Abstract: Rubber tape of uniform thickness is produced by causing an endless belt carrying on its underside a layer of coagulant to pass in contact with the surface of a body of rubber latex at a uniform rate and in a path positively determined by mechanical means, the time for which the belt is in contact with the latex in the bath being less than is required for complete penetration of the deposited latex layer by the coagulant, and, when the resulting layer of latex on the belt has become coagulated, separating the tape so formed from the belt and then washing, drying and curing the tape. The belt may be faced with a natural or synthetic rubber or vinyl chloride polymer that is not attacked by the latex or coagulant, while the coagulant may be an aqueous solution of calcium chloride of concentration 20 to 40% with or without zinc chloride in amount not more than 1/4 of the weight of the calcium chloride. The level of the surface of the latex in the bath relative to the travelling belt is maintained constant to within \sB0.05 inch while the tape may be folded longitudinally on itself after it has left the belt and before curing. Two or more tapes may be formed separately and laminated together before they are cured. Apparatus suitable for use in this process and comprising a bath adapted to contain liquid up to a constant level, means for feeding liquid to the bath at a controlled rate, an endless belt arranged to travel under a support or horizontally under tension in contact on ome surface with the surface of the belt which is to make contact with the liquid, is described.

Abstract: 844,303. Laying elevated rail tracks; supporting booms for overhead cranes. ALWEGFORSCHUNG G.m.b.H. Nov. 21, 1956 [Nov. 21, 1955], No. 35574/56. Classes 78 (4) and 104 (2). A crane for laying track sections supported wedge-like on piers and having a passageway for the sections to be moved and installed includes an upper chassis for supporting a crane beam or beams and two lower bogies which travel on previously-laid track sections, the upper chassis being supported on the bogies so as to tilt about an axis extending longitudinally of the track. As shown in Fig. 1, two track sections 1a, 1b have already been placed in position on piers 2a and 2b, track section 1c, is in the process of being lowered on to the piers 2b and 2c and the track section 1d is in the position prior to lifting. The crane consists of an upper chassis 6 mounted on two bogies 5a, 5b.. The bogies 5, Fig. 3, run on supporting-wheels 7 and are provided with guide-rollers 8 which engage the sides of the mono-rail track 1. The upper chassis 6 comprises two spaced beams 13 joined by box-shaped cross-members 14, one each end of the bogie 5, and overhanging sections 21 are pivoted at 20 to the front end of each beam 13. The upper chassis 6 can be tilted relative to the bogies 5 by a motor driven worm-gear 17 mounted on the bogie 5 and arranged to travel over a threaded spindle 19 linked to the upper chassis 6. The tilting movement of the chassis 6 relative to the bogies 5 may be automatically controlled by a pendulum weight suspended from the chassis 6 and acting on two limitswitches mounted on the bogie 5. The tilting may be about the centre line 10 of the track 1 or about an axis along the bearing-surface 12 of the piers 2. The chassis 6 is mounted on the bogey 5 through the intermediary of a ball-race to permit tilting. Jack frames 22 or intermediate sections 4 placed in the gap 3 between the ends of the tracks la, 1b, 1c support the crane on the piers 2a, 2b, 2c. The jack frames 22 comprise a cross-beam 22a and two upright members 25 pivotally mounted on the beams 22a and 24 so as to be adjustably tiltable by means of bolts 26. Hydraulic or threaded jacks 27 bear against the upper side of the beam 13 or overhang 21 to lift the crane off the track beam 1b. In the travelling position, Fig. 5, the jack frames 22 are raised above the track 1 and to one side by auxiliary hoists 28 on the beams 13 and cables attached to the members 25 via deflecting pulleys 29. A trolley 30 movably mounted on the beams 13 and overhang 21 is provided at its front and rear ends with cable winches 31 which by means of loose pulleys 32 engaging a transverse beam 33 passed under the track sections 1 lift the track sections into position. The overhang 21 may terminate as a cantilever 35, Fig. 1, in which case two hookmembers 36 arranged on the carriage 5a on each side of the track 1b are movable into position to engage the underside of the track section 1b, Fig. 6, by cranks 37 through a parallel link movement to prevent tilting of the crane when lowering a track section 1c into position.
