Abstract: 733,549. Making boxes. N. Z. INVENTIONS DEVELOPMENT CO., Ltd. June 26, 1953, No. 28729/54. Divided out of 733,525, [Group VII]. Class 18. A box nailing machine has means to automatically set the work table at a series of heights and to select nail feeds for a desired nailing pattern, enabling a box to be completed without manual readjustment of the machine. The work table E is slidable vertically and is supported by bolts 32, 32A or 32B on quadrants 30 pivoted to the table on either side of the machine and spring biased toward the right, Fig. 14. The means for raising the table comprises a rod 24 secured thereto and connected by springs 27 to a weighted lever 25, the weighted end being progressively raised by ratchet means (not shown) for sudden release. The released weight 26, towards the end of its fall, gives a resilient blow to the table, temporarily raising it, and enabling quadrants 30 to swing to the right. When the table settles under its weight, the bolts 32 have been positioned on stops 33 to support it. The table is lowered by a cam 35 acting on a rod 36 to force the quadrants to the left. Thus, as shown, the table may be positioned at three different heights corresponding to the bolts 32, 32A, 32B. Nails are driven into the work by known guns F, nails being selected for feeding to the guns by means as described in the parent Specification.

Title: Moulding reinforced plastic tubes
Inventor: DAVIES DRURY NORMAN
IPC: B29C41/20
Filed: 1954-10-06
Abstract: 788,063. Moulding resin tubes. DISTILLERS CO., Ltd. Jan. 5, 1956 [Oct. 6, 1954], No. 28742/54. Class 87(2). [Also in Group XXVIII] Fibre-reinforced tubes are centrifugally moulded by a process in which fibre 6 is assembled between the inner wall of the mould 1 and the outer wall of a perforated inner tube 4, made of a polymerized styrene compound and which comprises introducing inside the perforated inner tube a liquid resinous composition which is a monomeric styrene compound mixed with a compound copolymerizable therewith, e.g., an unsaturated polyester resin, rotating the mould so that the liquid resinous composition passes by centrifugal force through the perforations in the tube 4 to fill the air spaces between the fibres and . curing the resin while still rotating the mould. It is stated that the effect of the monomeric styrene compound is that the resinous composition becomes integrally bonded to the inner tube when cured. The size and number of the perforations 5 should be as small as possible consistent with an easy passage of the resinous composition. The fibrous material may be glass, asbestos, textile or metal filaments and may be in any suitable form such as rovings, woven fabrics or mats. Rovings may be packed into the space between the inner tube and the mould when the two are assembled, or woven fabric can first be wrapped round the inner tube, or glass rovings wound spirally round it, before insertion in the mould. End flanges 2 may be clamped on the mould to provide a resin-tight seal and the spindles 3 may be hollow to permit the introduction of an inert gas or to allow the resinous composition to be added after the end caps have been fitted. Heat is applied in any convenient way to cure or partially to cure the resin. If the cure is partial the tube can be removed from the mould and modified in shape, e.g. bent, before being finally cured by further heating. The speed of rotation should be low at first, and should not exceed that sufficient to cause the resinous composition to pass through the perforations. A suitable unsaturated polyester resin for use in the resinous composition may be obtained by esterifying saturated polyhydric alcohols, e.g., ethylene glycol, with alpha-betaunsaturated acids, e.g. maleic acid. Copolymers of styrene having a greater toughness than polystyrene are suitable for the inner tube, which is preferably extruded from toughened polystyrene, i.e. a polystyrene to which has been added a toughening agent such as rubber. Specifications 712,939 and 767,118 [Group XXVIII] are referred to.

Title: Improvements in or relating to power units including apparatus for producing power gas and an expansion engine driven by such gas
IPC: F02B37/04
Filed: 1938-10-04
Abstract: 519,806. Speed governors; gas turbines. SULZER FRERES SOC. ANON. Oct.' 4, 1938, No. 28761. Convention date, Nov. 27, 1937. [Classes 57 and 110 (iii)] [Also in Group XXVII] In a power plant comprising one or more internal-combustion engines 1 for producing power gas and an expansion engine or turbine 2 driven by the power gas, the speed of the engine 1 being automatically controlled by a governor 10 driven by the expansion engine, a relief valve 32 is provided in the pipe 2' connecting the engines 1, 2 and the pressure at which this valve will open to permit escape of power gas is varied according to the load on the expansion engine 2. As shown, the engine 1 is a two-stroke engine driving a compressor 4 delivering scavenging air to a receiver 5 and to a piston-controlled admission port 6 on the engine cylinder. A piston-controlled exhaust port 8 is connected through the pipe 2' to the turbine 2. An engine-driven governor 9 acts through a bell-crank lever 18 on the member 19 controlling supply of fuel by a pump 20 to the engine. A governor 10 driven by a turbine 2 acts through a lever 25 and rod 26 on the valve 27 of a fluid-pressure relay 11, which controls the admission of liquid under pressure from a pipe 29 to a pipe 15 or its escape to a pipe 28. On a reduction in speed of the turbine 2 below a set value, pressure fluid is admitted to the pipe 15 and acts upon a piston 23 to increase the compression of the spring 21 acting on the governor 9, so that the speed of the engine 1 is increased. The pressure fluid in the pipe 15 also acts through a piston 34 and spring 33 on the piston valve 32, which controls a relief passage 12 from the pipe 2<1>; on increase of the speed of the turbine 2 above a set value, liquid escapes from the pipe 15 and allows the valve 32 to open the pipe 2' to the relief passage and reduce the supply of power gas to the turbine. The setting of the governor 10 is adjustable by means of a hand wheel 30. A number of power-gas producing engines may be connected in parallel and may be controlled simultaneously or individually in accordance with the load on the expansion engine. In modifications, the power gas is supplied by a two-crankshaft opposed-piston engine, or by a free-piston engine in which' the number of strokes per. minute is controlled in accordance with the load on the expansion engine; a centrifugal compressor may be employed, and pneumatic, electric or mechanical transmission may be employed between the parts of the regulating apparatus.

Filed: 1971-06-18
Abstract: 1327496 Digital transmission; D.C. shift correction WESTERN ELECTRIC CO Inc 18 June 1971 [22 June 1970] 28780/71 Heading H4P To reduce D.C. shift in a multilevel signal a scrambler is employed at the transmitter having a single cell feedback shift register with modulo- À2 adder coupled thereto, the input of the scrambler receiving a digital signal and the output being converted to a multilevel signal. At the receiver a similar feedback register and adder is inserted after the multilevel converter. It is stated that tests have shown that a low number of cells produces better results with a probability p of binary 1 = 0À5 than higher numbers. The arrangement may be utilized for the binary transmission of video signals from a source 71 which are digitally integrated at 72, advantageously by a three-bit differential pulse code modulator, and passed through a one cell scrambler 73, illustrated in Fig. 5A (not shown), and through a transmission link 74. At the receiver input, a one cell descrambler, as illustrated in Fig. 5B (also not shown) passes signals to a decoder 76, similar to decoder 72 the output from which is passed to a receiver 77. In previous systems the probability p of binary l's varied from 0À39 to 0À57 on long term average: with a one cell arrangement as described p = 0À5 thus reducing far end cross talk and probability of error. A number of video sources after scrambling may be time division multiplexed on to a common channel.

Title: Rapid maturation of alcoholic beverages
IPC: C12H1/00
Filed: 1962-07-27
Abstract: A process for the rapid maturation of alcoholic beverages involves co-fermenting a wort with a yeast strain capable of fermenting carbohydrates to alcohol and a Penicillium variety capable of fermenting carbohydrates to ethyl acetate, and distilling out the alcoholic fraction and other volatile materials, which includes ethyl acetate.  The distillate may then be matured in containers of selected wood to increase further the ethyl acetate content and improve the taste, flavour, and aroma. Preferred are Saccharomyces cerevisiae or Saccharomyces ellipsoidae and Penicillium digitatum in a proportion of from one-tenth to one-thousandth of the amount of the yeast.  Examples are directed to the production of bourbon entry whisky, rye entry whisky, rum, grape brandy and apple brandy; the process is, however, applicable to sweet or sour beers obtained from any type of grain, e.g. maize, rye, barley, wheat, and rice, as well as mashes prepared from sugar cane, molasses, grapes, or apples.  The stillage or slop residue from the distillation is rich in vitamins, especially riboflavin and other components of the B complex, and may be recovered by spray drying or other conventional methods for use in animal feed mixtures.  In a typical example, a diluted bourbon cooker mash was prepared from a mixture of 250 parts distilled water, 75 parts maize meal, 25 parts of a mixture of toasted wheat, flour and malted barley, 10 parts Saccharomyces cerevisiae and 0.01 part of Penicillium digitatum spores with a pinch of potassium dihydrogen phosphate and potassium monohydrogen phosphate as a buffer.  This was incubated at 90  DEG F. for three days.  The wort was then distilled and had an ethyl acetate content of from 250 to 500 p.p.m. corresponding to that of a 4 to 6 year old bourbon.  The entry whisky was placed in charred white oak barrels and stored for from six months to two years; the matured bourbon had the flavour, aroma, and taste of a 4 1/2 to 8 year old bourbon and the ethyl acetate content ranged from 375 to 750 p.p.m.ALSO:The stillage or slop residue rich in vitamins, especially riboflavin and other components of the B complex, obtained after alcohol and other volatile materials have been distilled from wort co-fermented with a yeast strain such as Saccharomyces cerevisi  or Saccharomyces ellipsoid  and a Penicillium variety such as Penicillium digitatum, preferably present in a proportion of from one-tenth to one-thousandth of the amount of the yeast, is spray dried or otherwise recovered for use in animal feed mixtures.

Abstract: 1,109,155. Temperature responsive actuating elements; measuring temperature electrically; potentiometric voltage measurement. NEGRETTI & ZAMBRA Ltd. July 1, 1965 [July 15, 1964], No.29204/64. Headings G1D, G1N and G1U. A self-balancing potentiometer for measuring an input signal comprises a temperature responsive element, Fig. 2, actuated by an electric heating element 11 and which includes first and second tubular members 1, 2 rigidly connected at one end by a plug 3 and coupled by means of flexible members 9, 10 to a block 8 at their other ends so that differential expansion between the members 1, 2 causes the block 8 to tilt thus moving a lever 7 solid therewith, the lever actuating a dial indicator, electrical resistance coils 12, 13 being wound round and insulated from the members 1, 2, the coils providing an electric signal related to the temperature of the associated member, and these signals being compared with the input signal in an electrical bridge circuit, Fig. 3, to provide a control signal controlling the supply to the heating element 11. In Fig. 3 the input signal is applied to terminals 15, 16 and Ri and Ro represent the resistances of the coils 12, 13 respectively. Two fixed resistors R 1 , R 2 , and a constant voltage supply 14 are also provided in the circuit. When no potential difference is applied to the terminals 15, 16, the output of an amplifier 17 which controls the element 11 will be zero since the bridge will be balanced with Ri = Ro, and no potential difference between the points a, b. If a potential difference to be measured is applied to the terminals 15, 16 the amplifier output will not be zero, and the heating element 11 will be energized. Due to thermal lag between the members 1, 2 the resistances of the coils 12, 13 will alter and the bridge will become unbalanced. The element 11 will remain energized until the voltage between the points a, b of the bridge circuit equals that of the applied potential difference. The resulting movement of the temperature responsive element can be used to actuate a dial gauge. The members 1, 2 may be of the same material in which case differential expansion will occur due to thermal lag between the members 1, 2, or the member 2 may be of a material having a zero coefficient of expansion e. g. an alloy of iron with 36% nickel or a mixture of a synthetic polymer with lithium aluminium silicate, and in this case the resistance coil need only be provided for the inner member 1 and the bridge circuit can be simplified. The potential difference to be measured may be derived from a thermocouple or from a resistance thermometer so that the potentiometer may be used to measure temperature which can be indicated directly on the indicator coupled to the lever 7. In an alternative embodiment the temperature responsive device may comprise a double helix of a bimetallic strip with a single platinum resistance wire wound round with the coils. Modified electrical circuits for use with this device are given in the Specification.
