Title: Process for the production of stuffed products
IPC: A23L13/60
Filed: 1951-05-24
Abstract: <PICT:0704103/IV (a)/1> A film-forming, non-fibrous, plastic material is formed into a continuous, seamless tubing; the tube is stretched circumferentially by inflating it with a fluid and is then slit longitudinally to produce a sheet; the sheet is guided to a forming position where it is continuously shaped into tubular form with its longitudinal edges overlapped to form part of the wall of the tube, extending lengthwise along one side thereof, and these edges are continuously sealed; stuffing material such as sausage meat is continuously fed through a path inside the forming and sealing positions, and the tubular casing is continuously stuffed concurrently with its formation as it passes beyond the sealing position.  The tube may be made of regenerated cellulose, cellulose esters or ethers, synthetic resins, gelatine or casein. In particular it may be made of a water-insoluble, alkali-soluble hydroxyethyl cellulose or cellulose regenerated from viscose, or of cellulose obtained by denitrating cellulose nitrate.  As shown, a tube 4 is obtained by extrusion of plastic material from nozzle 2 into bath 6. Coagulating liquid is supplied to the interior of the tube through pipe 8 and withdrawn by pipe 10.  Air under low pressure is supplied through pipe 12 and is withdrawn through pipe 14.  The plastic tube is led through jacket 22 and between squeeze rollers 24, 26.  Air entrapped in the tube between rollers 26 and 28 causes the tube to be stretched transversely.  Rollers 28 may be driven at a greater speed than rollers 26 so as to stretch the tube longitudinally.  The tube may be washed by means of sprays 32.  The tube passes through a washing bath 34.  If desired it may pass through various treatment baths, e.g. baths for completion of regeneration of cellulose from viscose or cellulose nitrate.  The tube then passes through drying chamber 52.  Air enclosed in the tube between the pinch rollers 46, 48 inflates and expands the tube to the required diameter.  The dried tube is slit by the rotary cutter 59 working against the guiding foot 60 and the sheet so formed is spread open by guides 62.  The sheet may be further slit by rotary knives 68 to form two or more narrower sheets. Each sheet then passes to a separate stuffing device. Solvent or adhesive is applied to one edge of each sheet by a coating roll 72.  Weighted roller 70 takes up any slack in the travelling sheet due to non-uniformity in the rate of the stuffing operation. Stuffing material from container 77 is forced through nozzle 74. The edges of the sheet are overlapped by the tube-forming sleeve 73, and belt 78 presses the edges together and against the nozzle 74 to form the seal before the tube reaches the stuffing position at the end 79 of the stuffing horn.  If desired, the operations of forming, expanding, and slitting the original tube may be performed separately from the operation of forming the sheet into the final tube and stuffing the tube with meat or other material. Specification 674,542, [Group XXVIII], is referred to.

Title: Arrangement for Controlling the Energy Yield of a Load Element, e.g. a Lamp or Heating Device.
IPC: G05F1/12
Filed: 1967-03-15
Abstract: 1,176,033. Control systems for electrical loads. SIEMENS A.G. 15 March. 1967 [15 March, 1966; 2 June, 1966], No. 12245/67. Heading H2H. [Also in Division G3] In a control system for electrical loads such as lamps or heaters and of the type comprising anti-parallel connected thyristors T1, T2 for varying the A.C. voltage across the load La in accordance with an error signal dependent on desired and actual value load voltages, a squaring element Q is included in the actual value circuit Tr, G supplying the comparator D to obtain an invariable linear relationship between the desired value signal Xs and the energy yield from the load La. Thus in the case of a lamp load to which the described embodiment relates, a linear relationship is obtained between the setting of the control member, e.g. a potentiometer and the light output of the lamps irrespective of changes in the voltage waveform applied to the lamps caused by variations in the resistance of the load and the firing angle of the thyristors T1, T2. The circuit of a suitable squaring element Q is described, Fig. 2 (not shown). To avoid instability with sudden changes in the signal Xs, smoothing members are omitted from the actual value circuit Tr, G, Q but, to prevent loss of the abovementioned linear relationship, an amplifier V2 in the control circuit for the thyristors is provided with a differentiating feed-back C2 to cause V2 to have an integrating action. If several control voltages E1-E4 are used, the lamp voltage is limited to a desired maximum value decoupling the voltages E1- E4 through resistors r1-r4 and providing the transistor amplifier V1 with a negative feedback circuit comprising a resistor r5 and a Zener diode nl. The regulating circuit is made non-linear to ensure that small changes of control voltage rapidly bring the lamps up to their light emitting condition. Such non- linearity may be altered as desired, without affecting the abovementioned linear relationship between the signal Xs and the lamp light output, by connecting one or more negative feedback circuits in parallel with the amplifier V1, two such circuits being shown and comprising resistors r12, r13, diodes n5, n6, resistors r10, r11 and auxiliary sources of positive potential P1, P2. A typical characteristic relating Xs and the lamp voltage UL is described, Fig. 3 (not shown).

Abstract: 1459674 Digital-to-analogue and analogueto-digital converters SIEMENS AG 20 March 1974 [30 March 1973] 12269/74 Heading H3H A digital-to-analogue converter of the Shannon type is modified to decode an 8 bit binary signal in which 1 bit s is a sign bit, 3 bits m 1 , m 2 , m 3  determine in which of a number of linear segments of a characteristic curve the coded signal lies and 4 bits n 1 , n 2 , n 3 , n 4  determine the position within the segment. A decoder CD marks one of 8 outputs 0 to 7 in accordance with the m bits. States R 1  to R 4  of a shift register SR are loaded with the 4 n bits, stage R 5  is loaded with a "1" if output O of CD is not marked, and one of stages R 6  to R 12  is loaded with a "1" according to which one of outputs 7 to 0 respectively of CD is marked. The shift register is then read out serially, switch S1 being closed by any "1"s in stages R 1  to R 5  to charge capacitor C of the Shannon decoder, and switch S 2  being closed at a time dependent on which one of register stages R 6  to R 12  was in the "1" state to connect the capacitor C to the output amplifier V via a polarity switch S 3  controlled by the sign bit S. Alternatively, the polarity of the pulses from the generator CG may be controlled by the sign bit s. The decoder may be used in the feedback path of an iterative coder, Fig. 1, not shown.

Title: A machine for wrapping goods
Inventor: SMITH DONALD WILLIAM BRADLEY
IPC: B65B9/02
Filed: 1964-03-25
Abstract: 988,508. Wrapping machines. C. F. TAYLOR (UNITY DESIGNS) Ltd. March 25, 1964, No, 12538/64. Heading B8C. A wrapping machine comprises supports for two separate sources of wrapping film, a pair of members movable to and fro in a horizontal plane so that webs of film from both supplies are trapped between them, with means carried by the members to sever the webs and heat seal the pair of ends thus formed, and a platform to support goods when placed upon the sealed ends while the webs are sealed as before above the goods to enclose said goods. Wrapping film from supplies 18, 22 is fed over rollers so that it passes between the movable members 30, 36, one of which carries a heating wire. Operation of the pneumatic pistons 50, 51 pushes the members together, Fig. 7, while rollers on a bracket 92 and a roller 111 draw film from the supplies. The films are now trapped between the members and are severed by the heated wire, which also seals the pair of ends thus formed on opposite sides of the line of severance. When the members are withdrawn, Fig. 8, there is sufficient slack film drawn from the supplies to allow goods to fall between the films and on to the platform 60, without setting up undesirable tensions in the web. The films may then be sealed above the goods. The wrapped goods are ejected from the machine, Fig. 10, down a ramp 70, when a piston 80 operates a rod 76. The operation of the cycle is repeated automatically. The position of the rollers 99<SP>1</SP>, 107 may be adjusted according to the size of the goods to be wrapped. The two rollers 99<SP>2</SP>, 109 immediately above the movable members are set to hold the film away from the members so as to prevent premature contact with the heating wire. The platform is also height adjustable according to the size of the goods to be wrapped and may be piston operated in order to control the lowering of the goods into the wrapping position. Rapid operation of the machine is facilitated by cooling the contacting faces of the movable members. The goods are usually wrapped in heatshrinkable film, which may be multi-ply, and after ejection are conveyed through a heated chamber 80 that the film is shrunk tightly on to the goods.

Abstract: 199,366. Siemens Schuckertwerke. June 16, 1922, [Convention date]. Refrigerating, absorption machines and processes for. - In a continuous-cycle system without a circulating pump or pressure equalizing valves, particularly a system employing water and sulphuric acid as the refrigerant and absorbent respectively, there is provided a passage for the refrigerant-freed absorbent from the boiler 2 to the absorber 1, comprising an upwardly extending pipe 11 through which the absorbent is drawn by the upward rush of the gaseous refrigerant. This pipe discharges into a gas separator 10, from which passages 12, 14 communicate respectively with the condenser 15 and absorber 1. The pressure in the separator is sufficiently in excess of that in the absorber to compensate for the height of the column 14, so that the refrigerant-feed absorbent passes into the absorber, and returns, in a saturated condition, by the pipe 3. In a second form, Fig. 2, in which the separator 36 is situated at a higher level than the absorber 30, the superior pressure in the separator is prevented from forcing too great a quantity of refrigerantfreed absorbent into the absorber by arranging a capillary connection 40 therebetween and by providing buffer chambers 41, 48 communicating with the electrically-heated boiler 32. The condenser and evaporator are shown at 38 and 54 respectively.
