Title: Improvements in or relating to wrapping machines
IPC: B65B11/54
Filed: 1949-07-14
Abstract: 692,858. Wrapping-machines. SHARP & CO., Ltd., and FELTON, I. A. July 13, 1950 [July 14, 1949], No. 18623/49. Class 94(i). A bunch-wrapping machine comprises an apertured plate for receiving and supporting a sheet of wrapping material, retaining means for supporting a partially-wrapped article after the article and wrapping material have been passed through the plate, and an iris diaphragm disposed between the retaining means and the plate whereby the contraction of the aperture is adapted to draw the edges of the wrapping material together round the article while it is held in position by the retaining means. In one form the machine comprises an apertured die plate 26, located by an apertured plate 2 forming the upper wall of a casing 1, and a cup-shaped supporting member 3 on the upper end of a shaft 4 which is slidable vertically in a sleeve 5 to an extent determined by a stop 4A and is normally held in its upper position by a counterweighted lever 8. The plate 26 co-operates with an upper die plate 14 secured to a counterweighted carrier 16 which is pivoted on a shaft 21 so that the die plate may be swung clear to allow a wrapper to be placed on the plate 26 and then lowered to a position determined by adjustment screws 25 to grip the wrapper lightly. The plates may be lined with felt or, if it is desired to pleat the wrapper, may be formed with co-operating ribs or steps. Immediately below the plate 26 is an apertured iris diaphragm comprising curved, overlapping leaves or plates 12 linked to a control handle 13, (see Fig. 1 not shown), which may be coupled to the lever 8 so that movement of the handle to expand or contract the aperture also raises or lowers the member 3. The article to be wrapped is placed on the wrapper and then forced through the apertured die plates into the supporting member 3 by a plunger 33, having a rubbercovered head 34, which is operated by a spring-loaded hand lever 37, the wrapper being thus folded about the article in the form of a cup. The handle 13 is then operated to cause the aperture in the diaphragm to contract and draw the upwardly-extending parts of the wrapper over the top of the article. The plunger is then raised, the diaphragm opened sufficiently to enable a gummed label to be placed over the bunched ends of the wrapper and the wrapped article is ejected by upward movement of the member 3 after the diaphragm has been fully opened. If it is desired to heatseal the bunched end of the wrapper, the machine is fitted with a heat-sealing member, (see Fig. 3 not shown), which is mounted on a pivoted arm so that it may be moving down into engagement with the wrapper after the diaphragm has been partially opened. In a modification, Fig. 4 (not shown), the slidable member 3 is replaced by a set of resilient members disposed in the form of a hollow cylinder below the diaphragm, and the dieplates by a single fixed aperfured plate. Specification 644,126 is referred to.

Abstract: 1,048,384. Semi-conductor Circuits. HONEYWELL Inc. May 10, 1963 [May 10, 1962], No. 18645/63. Heading H3T. An electrical process-control system in which a control device of the system is energized in accordance with a selected one of a plurality of input signals corresponding to respective conditions existing in the process, comprises means for feeding back negatively a portion of the output signal of the system for combination with each of the input signals, means for selecting whichever of the combined signals has one extreme (positive or negative) amplitude and means for amplifying the selected signal to derive an output which is used to energize the control device, the signals for negative feedback being derived by means of a mechanical or electronic chopper to which a portion of the output signal is applied to develop a chopped signal which is fed back to each input through respective secondary windings of a transformer to whose primary winding the chopped signal is applied. Input signals applied at respective input terminals are combined with fed-back signals applied over respective capacitors to the input terminals of respective transistor amplifiers 20, 40, Fig. 1 (not shown). The amplified outputs currents are then applied to respective input terminals 6a-6d of a signal selector comprising diodes 92a-92d and resistors 94a-94d and so biased by current from a positive supply terminal through variable resistor 86 that the potential appearing on line 88 corresponds to whichever of the input currents applied to terminals 6a-6d has the least magnitude. A circuit comprising diode 98 and resistor 100 supplied with a standard input current from source 102 and potentiometer 104 serves to protect transistors 106, 108 by ensuring that if the inputs applied at 6a-6d exceed a safe magnitude, that applied to circuit 98, 100 is passed to the transistors. The selected input is amplified by transistors 106, 108 for passage to a control device 52 such as a control valve, a pump control or control means for the supply of electrical energy. A portion of the output signal tapped off from potentiometer 218 is passed to a choppermodulator constituted by a transistor 220, diode bridge 224 and transformer 226 to which an A.C. supply is connected. The chopped signal is coupled from respective secondary windings 60a-60d through respective rectifiers and shaping circuits to the transistor amplifiers 20, 40 preceding the selection circuit. The transistor chopper modulator circuit may be replaced by a conventional mechanical chopper followed by a push-pull amplifying stage, Fig. 2 (not shown).

Title: Process for the preparation of acetyl methyl carbinol and diacetyl
IPC: C12P7/26
Filed: 1929-06-25
Abstract: 315,264. Verhave, T. H. July 10, 1928, [Convention date]. Acetylmethylcarbinol ; diacetyl.-Acetylmethylcarbinol is produced by inoculating a mash containing carbohydrate, a nitrogen compound, phos. phate, and a carbonate, with a culture of bacteria which normally produces 2 : 3-butyleneglycol, and subjecting the fermenting mash to an intensive aeration. The acetylmethylcarbinol is separated by distillation or by extraction with solvents, or the fermented mash mav be treated with biological or chemical oxidizing agents, for example, oxidizing bacteria (acetic acid bacteria) carried on pumice, or ferric chloride and dilute sulphuric acid, to convert the acetylmethylcarbinol into diacetyl, which can then be separated by distillation. In an example, beet molasses are diluted with water, boiled with the addition of phosphorite and calcium carbonate, cooled, and inoculated with a culture of Aerobacter aerogenes at 40‹ C. in a closed fermentation vat, previously sterilized. When fermentation has begun, a rapid and increasing current of air is blown for some hours through the mash, which is then extracted with carbon tetrachloride, and the acetylmethylcarbinol recovered by distilling off the solvent. A further example is given in which the rate of aeration is increased in stages during the process, the acetylmethylcarbinol formed being oxidized to diacetyl by means of ferric chloride. The air blown through the mash is washed for the recovery of acetylmethylcarbinol. The production of 2 : 3-butyleneglycol by the fermentation of sugar with Clostridium polymyxa, and the production of acetylmethylcarbinol by passing oxygen through a solution of 2 : 3- butyleneglycol inoculated with Aerobacter aerogenes, are referred to.
