Title: Improvements relating to beating up mechanisms for looms, especially for manufacturing terry-towelling
IPC: D03D27/08
Filed: 1939-04-12
Abstract: 527,711. Beat-up motions for looms. BERG. G. April 12, 1939, No. 11067. [Class 142 (iii)] In a beat-up mechanism for terry looms, the connecting rod is connected to the lay by an eccentric 6 and pin 7, and the extent of beat-up is varied by adjusting the position of the eccentric against the action of a spring 10 by means controlled by a tappet 18, or from a dobby or jacquard. The extent of beat-up is lessened when a hook 12 is in position during the beat-up I to engage a pin on a bracket 8 fixed to the eccentric. The pivot 14 of the hook may be resiliently mounted. The maximum beat-up is limited by contact of the bracket 8 with a stop 9.

Abstract: 800,454. Ohmic resistors. IGRANIC ELECTRIC CO., Ltd. April 18, 1955 [April 26, 1954], No. 11084/55. Class 37. In a resistor of the type having a frame supporting insulated rails on which grids of resistance material are stacked, the grids have lugs and a body portion which lies wholly to one. side of the centre line of the grid, thus enabling the grids to be readily mounted and interchanged and their heating to be minimized. Figs. 1 and 4 show a resistor in which insulated supporting rods 12, 14 and 16, 18 are attached to brackets 20, 22, 28, 30, the former pair of which are fixed to channel members 24, 26 and the latter pair are slidably carried by these members. Grids 10, Fig. 5, punched from resistance material such as nickel-chromium, coppernickel or any suitable chrome-iron alloy have lugs 10b, 10c and a body portion 10a which are disposed on opposite sides of the centre line of the grid, and are stacked in zigzag fashion on the supporting rods, alternate grids being preferably welded together at one end and spaced apart by insulated spacers 32, Fig. 6, at the other. Electrical connections to the resistor are made by terminal plates 34, Fig. 3, inserted in the stack as required or connecting tabs may be formed on the grids. The brackets 20, 22 and 28, 30, as shown in Fig. 1, are free to slide over pins 46 as the grids 10 expand and contract longitudinally with heating and cooling. By removing fasteners 42, Fig. 1, the grid stack may be withdrawn without altering the spacing of end channels 24, 26. In a modification, shown in Figs. 7 and 8, mounting rods 104 and 106 are held by channel members 100, a groove 126 in nut 112 allowing the rods to slide between tabs 120, 122 on longitudinal change in dimension of the rod. Change in length of the grids is taken up by the sliding of rod 104 in cut-out 124. The grids 142 may be shaped as shown in Fig. 9.

Title: Improvements in or relating to a variable stencil device
IPC: B41K1/32
Filed: 1956-04-12
Abstract: 789,496. Stencilling-apparatus; selective printing. CANTONI, C. April 12, 1956 [April 12, 1955], No. 11152/56. Classes 100(2) and 100(4) A stencil device comprises a plurality of independently movable strips of pliable sheet material, each having a plurality of stencils spaced along it, spaced pairs of rollers for winding on the opposite ends of the strip, means for guiding a portion of each strip intermediate the rollers into a working position where all the strips are co-planar and side by side to rest against a surface to be marked, and manually controlled means for moving each strip lengthwise to place any desired one of its stencils in the working position. Four stencil strips 18, Figs. 1 and 2, of sheet steel or other sheet material, and formed with evenly spaced stencils having pattern cuts representing numerals, letters or other signs are wound on rollers 13, 15 supported on shafts 14, 17 in housings 21, 22, so that their intermediate portions pass across and form the bottom of a central structure 10, resting on an article to be marked. Springs 16 associated with the rollers 15 urge the rollers counterclockwise. The rollers are prevented from rotating by stop members 28 engaging teeth or wheels 27 fixed to the rollers 13 and releasable by buttons 29 to allow the strips to move through one stencil length. The strips are retractable by means of a knob 32 on an inner shaft 31 carrying pivoted members 34 urged by springs 35 through openings 33 in the shaft 14 and into grooves 36 in the rollers 13. The members 34 are closer together than the length of a roller 13 so that for any one axial position of the shaft 31 only one member 34 and roller 13 are in engagement. The shaft 31 is moved axially by the knob 32 to engage the requisite roller and is then rotated by the knob to retract the requisite strips. A rack 43 on the shaft 31 comprises annular grooves and engages a pinion 42 on a shaft 40 to rotate a pointer 37 over a dial 38 and indicate which roller 13 is in engagement. Pressure members 30 engage the surfaces of the strips to maintain tension during retraction and springs urge the members 30, 28 into operative position.

Title: Method and equipment for the pyrolysis and synthesis of hydrocarbons and other gases
IPC: C07C2/80
Filed: 1966-03-15
Abstract: 1,138,971. Treating gases with discharges. WESTINGHOUSE ELECTRIC CORP. 15 March, 1966 [6 April, 1965], No. 11261/66. Heading H5H. [Also in Division C5] A method of synthesizing a desired gas from a process gas containing all the elements of the desired gas comprises the steps of passing a stream of the process gas through an electric arc which is periodically varying in intensity so as to form alternate relatively hot volumes of gas which are heated to a temperature at which dissociation of the molecules of the process gas occurs, and relatively cold volumes of gas, mixing said relatively hot and cold volumes to produce a gas temperature within the range of temperatures at which the desired gas is a stable recombination product, and thereafter quickly cooling the mixture to stabilize a substantial portion of the desired recombination product. The periodic variation of the arc is preferably obtained by energizing the arc from an A.C. source. A single arc heater having two electrodes connected directly to a transformer may be used and will produce alternate hot and cold volumes of gas if the gas residence time in the heater is of the order of the duration of one power cycle. An arc heater as described in Specification 1,023,730, apart from having a wider exhaust nozzle, is suitable. Two arc heaters may be used, as in the arrangement shown in which methane or other gas passes through inlets 264 and 267 to arc heaters 213 and 214 connected in parallel across an A.C. supply through rectifiers 221 and 226 so that heating occurs alternately in the two heaters on alternate halfcycles of the supply. A mixing chamber 266 has an exhaust nozzle 272 containing a spray head 271. Outlets 265 and 268 may be diametrically opposite. The mixing chamber 266 may be spherical or cylindrical, and may contain a water cooled baffle to assist mixing. The rectifiers may be biased, and H.F. generators may be provided to ensure rapid re-striking of the arcs. Further alternative embodiments have three heaters or six heaters connected to a 3 phase supply.

Title: Improvements relating to surgical operation tables
Inventor: THORPE RONALD JAMES
IPC: A61G13/00
Filed: 1956-04-13
Abstract: 810,956. Surgical tables. ALLEN & HANBURYS Ltd. April 11, 1957 [April 13, 1956- Nov. 26, 1956], Nos. 11362/56 and 36161/56. Class 52(3) The platform of a surgical table is in two sections 2, 3 and can be tilted as a unit about a transverse pivot 8 carried by a yoke 7 which is connected by a longitudinal pivot 9 to the support column 10. A drive shaft with a single operating handle &c. 12 extends beneath the platform at one end and three independent drives can be selected by an adjacent lever 14 to tilt the platform about either pivot axis or to adjust the relative angularity of the sections 2, 3. Removable head and leg extensions 5, 6 are provided and are preferably interchangeable. The leg extension may also be angularly adjustable by a fourth drive gear and can be in two longitudinal sections. The drive shaft 13, Fig. 3 is moved axially by the gear lever 14, working in a gate 15, to operate a dog clutch 16 which when engaged drives a gear train 17, 18 and bevel wheel 19 operating a shaft 21, Fig. 1, which rotates a screwed transverse shaft 23 by which the platform can be tilted in either direction about the longitudinal pivot 9. A hollow shaft 25 surrounding the shaft 13 is controlled by the lever 14, when the dog clutch 16 is disengaged, to rock a plate 26 carrying two idler pinions which can selectively connect a spur wheel on the drive shaft to lay shaft pinions 29, 30. As shown in Fig. 3 one idler pinion 27 is engaged with its corresponding pinion 29 and rotates a bevel gear 31 operating a screw threaded shaft in a sleeve 33 to tilt the platform about the transverse pivot 8. Alternatively the other idler pinion can engage the pinion 30 to drive the bevel gear 34 which operates a similar screwed shaft in a sleeve 36 to alter the angle between the platform sections 2, 3. The additional drive for the leg extension adjustment can be derived by fitting a two-way selectively operated gearing to the dog clutch 16 whereby it can operate either to tilt the platform about the longitudinal pivot 9 or to adjust the angle of the leg extension section or sections.

Title: Heat sealed package
IPC: B65D75/30
Filed: 1972-03-11
Abstract: 1365769 Heat-sealed packages MARDON FLEXIBLE PACKAGING Ltd 9 March 1973 [11 March 1972] 11465/72 Heading B8C A heat-sealed package, containing for example disposable surgical instruments such as syringes, &c., and which can be sterilized after heat sealing and retain the contents sterilized, and which can be opened so that the contents can be removed without contamination, comprises opposing sheets of materials which are heat-sealed together by a peelable seal along marginal portions at least one of the sheets comprising a neutrally-sized paper which is preferably glazed on its outer surface. The term neutrally-sized is defined as sized under neutral conditions with a pH value in the range of 7À2 to 8À3 inclusive and using an alkyl ketene dimer as the sizing agent. The glazed surface of the sheet of paper is formed by drying the paper on a heated, polished metal, cylinder, the unglazed surface of the paper remaining relatively rough, and the paper preferably having a Bendtsen porosity between the limits of 60-120 c.c./min. and a basic weight not less than 50 g/m<SP>2</SP>. and preferably not less than 55 g/m.<SP>2</SP> The other sheet need not be porous and can be either a film of thermoplastics material, a laminate of similar, or dissimilar, layers of plastics materials or, a polyethylenecoated paper. If, however, the latter is used for gas-sterilization purposes the coating on the paper should be of a discontinuous form or, of such a porosity as to achieve permeability. In one example of forming a package a sheet of neutrally-sized Kraft paper, machine glazed on one surface and with a heat-sealable lacquer adhesive, is peelably sealed along its marginal edges to a non-porous polyester/polyethylene film to form a package containing an article, the interior of the package being gas sterilized. The porous base material of the other sheet of the package may be a non-woven fabric, or paperlike, material. The external glazed surface of the package is suitable for good quality printing. Several other examples for forming a package according to the invention are described. The neutrally-sized paper base may comprise the closure of an open-topped, rigid, thermo-formed container.

Title: Improvements relating to the production of streptokinase and streptodornase by fermentation
IPC: C07K14/315
Filed: 1952-05-08
Abstract: Mixtures of streptokinase and streptodornase are obtained by inoculating an aqueous medium containing basic nitrogen material with a strain of beta hemolytic streptococci and fermenting, there being added to the fermentation medium before fermentation has proceeded for a period of 10 hours, between 1500 and 6000 parts by weight of a sugar for each 1000 parts by weight of the basic nitrogen material, at least 8 per cent of said sugar being added before the fermentation has proceeded for a period of 4 hours, and maintaining the pH of the medium between 6.0 and 8.5, and preferably 6.5 and 8.0, during fermentation.  The addition of 2000-3000 parts of sugar to 1000 parts of basic nitrogen substance is preferred.  It is also preferred to add all the sugar to the medium before inoculation.  The temperature of fermentation is 32 to 40 DEG C and preferably 36-38 DEG C.  The basic nitrogen material is such as to furnish in free or combined form amino acids such as glycine.  Examples are animal and plant protein digest, e.g. enzyme hydrolyzed casein, and particularly hydrolysed casein with glycine as shown in Specification 715,103. Specified sugars are sucrose, maltose, dextrose, glucose and mannose. The fermentation medium should contain a sulphydryl reducing agent such as thioglycolic acid, thiomalic acid or glutathione.  Other materials which may be present are (a) growth-promoting agents such as potassium dihydrogen phosphate, potassium bicarbonate, uracil, adenine sulphate, nicotinic acid, pyridoxine, tryptophane, calcium pantothenate, thiamin hydrochloride, riboflavin and cystine; (b) salt mixtures such as magnesium sulphate, copper sulphate, zinc sulphate, manganese chloride and ferrous sulphate in dilute hydrochloric acid.

Filed: 1936-04-23
Abstract: 457,086. Screw-and-nut gearing. MAAG - ZAHNRADER UND - MASCHINEN AKT.-GES., 219, Hardstrasse, Zurich, Switzerland. April 23, 1936, No. 11640. Convention date, April 24, 1935. [Class 80 (iii)] Nuts for use with screwed spindles of machine tools, measuring apparatus, &c., where great accuracy is required, are prevented from wearing rapidly by forming in the nut 2 one or more slots or grooves 4 to which lubricant is supplied under pressure through conduits 5, 6. The nut is in two parts and the grooves are arranged at the joints, but it may be in a single piece when one groove only may be provided. The grooves extend close to the ends of the nut. In order to ensure a film of oil on each thread the latter are, at 7, Fig. 2, bevelled and rounded and the tops of the threads have a slight clearance with those of the spindle and this, in conjunction with the oil films, ensures practically no metallic contact at these points. The halves are held together and secured to the machine part 1 by a tapped ring 3, a similar ring 9 and close-fitting sleeve 8.
