Title: Improvements in and relating to cleaning animal intestines
IPC: A22C17/16
Filed: 1939-06-05
Abstract: 519,611. Sausage casings STRIDH, C. H. June 5, 1939, No. 16489. [Class 28 (ii)] Intestines are cleaned by passing them first between rollers 3, 4 and then between a scraping or cleaning roller 6 and a pressure member 7. The roller 3 has a transversely ribbed surface and is revolved at high speed ; it frictionally entrains the roller 4 which is of resilient material. e.g., rubber, and has a smooth surface. The roller 6 is rotated at the same speed as the roller 3, but in the opposite direction. The roller 6 comprises radially-arranged yielding plates 9 the outer ends 10 of the plates being bent in opposite direction to the direction of rotation. The pressure member 7 is stationary and is eccentrically mounted whereby it may be moved towards or away from the roller 6. Between the rollers 3, 4 and the members 6, 7 a baffle 16 is pivotally arranged on an axis 17, so that when sheep or swine intestines are to be cleaned, the baffle is, tilted to the left as in Fig. 1, so that the intestine 12a drops in a loop in a hot-water bath 22 beneath the roller 6 and 'then passes upwardly between the members 6, 7, the intestine being pulled in this direction by means not shown. When the intestines of cattle are to be cleaned, the baffle 16 is tilted to the right, the intestine passing directly through the members 6, 7 in the same direction as through the rollers 3, 4. The intestines are delivered to the rollers 3, 4 by a relatively low-speed roller 11, having transverse ridges, and a screen 13 which is substantially tangential to the. roller 11 and adjustable towards and away from the roller 11 by an eccentric device 14 to control the width of the interspace 15 through which the intestine passes to the rollers 3, 4. The'striking action of the ends 10 of the plates 9 holds back the tissue loosened from the intestine and expels it at the end of the intestine. The plates 9 are perforated and slitted to increase their elasticity and are held in place between washers having conical recesses which engage corresponding inclines on the ends of the plates.

Filed: 1957-05-24
Abstract: 836,634. Electrical measuring systems. NAPIER & SON Ltd., D. May 13, 1958 [May 24, 1957], No. 16571/57. Class 40 (1). Temperature compensation of a strain gauge resistance is achieved by combining a thermo. couple physically and electrically with the resistance. Fig. 2 shows a nickel-chromium strain gauge 25 in which the thermocouple consists of leads 11, 12 of dissimilar metals such as alloys of chromium and aluminium. In Fig. 1, the strain gauge is shown at 10 and the dissimilar leads 11, 12 are joined to low-resistance leads 13, 14, the cold junctions 15, 16 being maintained at constant temperature in a bath 24 of melting ice. The element 10 is incorporated in a bridge circuit which is set up by balancing with the element cold and unstrained by adjustment of resistance 18, then heating the element and adjusting the polarizing voltage by potentiometer 22 until the galvanometer 20 again indicates zero. It is stated that the system also compensates for change in lead resistance and for strain modification due to differential thermal expansion between the gauge and the stressed article.

Title: Improvements in and relating to vacuum producing apparatus for paper making machinesor the like
IPC: D21F1/48
Filed: 1937-06-15
Abstract: 497,282. Suction boxes for paper-making machines. POIRIER, E. June 15, 1937, No. 16639. Convention date, May 6. [Class 96] For extracting water from a travelling web in paper-making machines or the like, the web runs in water extracting relationship over a vacuum box 2 with which communicates a vacuum casing 6 into which water extracted by the box is delivered, and a drop leg 7, divided into a plurality of sections so arranged that the number of such sections utilized at any time to carry away water from the casing automatically changes in accordance with changes in the volume of water disclosed, leads downwardly from the vacuum casing to a well 8 with adjustable weir 10 and outflow 12. Usually several boxes are arranged side by side each connected by a pipe 4, containing valve 5, to the vacuum casing 6. In the Figure, the drop leg is shown divided into three sections a, b, c, by baffles 14, two inch pipes leading from sections a, b and a four inch pipe from section c. A small flow of water runs almost exclusively through pipe a, a larger flow overflowing the first baffle and being led away by pipes a and b while pipe c is only used when the water in the casing is sufficient to overflow both baffles. To provide a higher vacuum when required, e.g. when starting up a line 15 from an external source of suction, e.g. suction pipe 16 running to the couch roll leads into casing 6. A spring operated valve may be provided in this pipe to open when the pressure in the casing 6 rises above a predetermined point. The lip d of pipe 15 is upturned so as always to be above the water level. In a modification, the pipe 15 may be left open and projecting into the bottom of pipe 4. Normally this pipe will be submerged in water and its diameter being small, it will merely carry off a small volume of water. When the flow of water is small however and the pressure is tending to rise, the pipe 15 will carry off a relatively large amount of air and hence reduce the pressure. The tip of the pipe 15 may be disposed at any desired level. An adjustable spring controlled valve 20 open to the air is provided in a pipe leading into the box at a point remote from the pipe 4, but inside the baffles 3 provided for adjusting the effective width of the box. This valve prevents the vacuum in the box rising to too high a degree.

Abstract: 183,673. Burdon, W. M., Burdon, M. M., and Burdens, Ltd. June 17, 1921. Liquid-fuel fittings.-In a liquid-fuel furnace adapted to burn heavy oils, wherein the fuel on its passage to the burners is heated when the furnace is in operation by air heated by passing through pipes D located in the furnace, which also heat the air for combustion, a separate heater is provided for starting the furnace. The heater 12, Fig. 1, comprises a firing-chamber 18 and a heating-chamber 19, connected by a passage 20 in a partition 17. The chamber 18 contains a burner 21, connected by pipes 22, 23 to the air main G, and by a pipe 24 to a supply of light oil-fuel. The chamber 19 contains a heating- pipe 11, in the form of a double return bend, connected on the one hand by the pipes 10, D, and C to the air main G, and on the other hand by a pipe 13 to a coil in the fuel tank B, and by branches 14, 15, to a jacket 4 surrounding the fuel supply pipes 2, and a distributor 16 at the bottom of a sheathing 5 surrounding the vertical fuel pipes 3, respectively. To start the furnace the burner 21 is lighted, and the combustion products heat the pipes 11, whereby heated air is supplied by the pipes 13, 14, 15 to the coil in the fuel tank, jacket 4, and distributor 16. When the oil is sufficiently thinned, the furnace burners are lighted, and the burner 21 shut off, whereupon air heated in the return bends D serves to preheat the fuel. In a modification, Fig. 4, a branch 29 from the air-pipe D feeds a fuel burner 30, at the mouth of a jacket 4 surrounding the fuel supply pipe 1, and connected to a supply of light oil-fuel. To start the furnace the burner 30 is lighted, and when the oil is heated sufficiently the burner A is lighted, the burner 30 is shut off and then serves to blow heated air into the jacket 4. A blow lamp may replace the burner 30, and steam or coal gas burners may replace the hot air for heating the jackets and coils. The fuel tank B is provided with an inclined partition with an opening at its lower end, so that the whole of the oil passes over the heating coil in the tank before entering the supply pipes 2.

Abstract: 757,448. Selective printing. AKTIEBOLAGET ADDO. June 9, 1954 [June 12, 1953], No. 16961/54. Class 100 (4). In an arrangement in printing registers for listing, calculating, book-keeping and like machines, in which each order mechanism has a. hammer, for a vertical typebar, which can be locked, against the action of resilient means, in a starting position from which it is releasable for movement, by the resilient means, to make an impression, by an individual locking device, each locking device having a latch 7 which locks the associated hammer when the associated type bar indicates a value other than zero, and a locking lug 10, 11, 14 which, for interlock, overlaps a portion of another order mechanism to maintain the hammer associated with the lug in the starting position when the hammer of the second mechanism is maintained in the starting position, the overlapped portion 12 in' at least one order, or the lug overlapping that portion and associated with at least one other order, being movably arranged and displaceable to permit cancellation of the interlock, each hammer has an upwardly directed arm which, when the hammer is not locked, can be moved by the resilient means to a position in which the hammer is inoperative, the movable locking lug or overlapped portion is arranged on an upwardly directed arm, the latches 7 engage with other arms 5 on the hammers, and the movable locking lug or portion has an operating arm 21 projecting away from the platen at a higher level than the arm 5 of its hammer. In the construction shown, printing hammers 1-4 type, respectively, pence, unit shillings, tens shillings and pounds. Lug 10 on hammer 1 overlaps hammer 2. Lug 11 on hammer 2 extends past hammer 3 and overlaps a portion 12 of member 13 which is movable on hammer 4, pins 15, 16 engaging in slots 17, 18, urged upwardly by spring 19, and moved downwardly through projection 21 by a key-operated lever &c. Lug 14 on hammer 4 overlaps the next hammer. Hammer 3 has no lug and is therefore always swung into inoperative position when the associated type bar does not indicate a " 1 " (ten shillings). When member 13 is positioned as shown, so that portion 12 is engaged by lug 11, and a type bar of one hammer indicates a digit other than zero, all the hammers, except hammer 3, to the right of that hammer, even though their type bars indicate zeros, will be prevented from swinging to inoperative position by lugs 10, 11, 14. Hammers to the left of the highest order where a digit other than zero is indicated will be swung to inoperative position, so that no printing takes place to the left of that digit, but digits including zeros are printed to the right thereof. If projection 21 is depressed so that portion 12 cannot be engaged by lug 11, hammers 1-3 will swing to inoperative positions if they indicate zeros.
