Title: Improvements relating to the mechanical dressing of fish
IPC: A22C25/00
Filed: 1950-01-18
Abstract: 676,815. Fish, filleting. FISADCO, Ltd. Dec. 29, 1950 [Jan. 18, 1950], No. 1356/50. Class 28 (ii). The flesh of fish, particularly at the belly flaps is cut off from the belly ribs by resiliently pressing the flaps against one or a pair of flat guides 28, 30 as the fish is carried past one or a pair of disc knives 6 and 8 rotating parallel to and at a set distance from the guides to cut a slice from each belly flap of the fish. The fish 2 is conveyed around, tail first, in the peripheral groove 3 of a rotated horizontal drum where it is first split longitudinally and gutted by other known devices. Thereafter its belly is spread open to V shape as it moves on to and over a central fixed guide 26 with the flat guides 26, 28 as extensions of the V. Cam-operated resilient fingers 32 press the belly flaps down on to the V guides 26, 28 which guide the belly flaps between the mutually inclined disc knives 6, 8. Each disc knife 6 is parallel to its corresponding guide 28 and can be adjusted towards or from its plane to give the required thickness of slice to be cut off. The guides 28 and 30 are carried by arms 38 and 40 which are pivoted at 42 and 44, Fig 2 (not shown). The thickness of the slice cut off can be varied by screws 46 moving the arms 38 and 40 to vary the offset distance between the trailing edges 29 and 31 (not shown) of the guides and the cutting edges of the knives 6, 8. The upper and lower sets of resilient bellcrank fingers 32, 34 are pivoted on shafts 50 &c., and are urged against the fish by springs 54 &c. The springs 54 are connected to a triangular plate 60 pivoted on a lever 62 movable by a screw to vary the spring tension to suit the softness of the fish. The upper and lower sets of fingers 32 &c., are intergeared by toothed segments 78 to be moved in unison toward or from the disc knives by a cam surface, not shown, on the drum 4. This cam is so shaped and positioned that as a fish approaches, the fingers 32 &c., are lifted away from the guides 28, 30 to allow the belly flaps to enter freely between the guides and the fingers after which the cam roller is allowed to drop so that the fingers are allowed to press by springs 54 &c., against the belly walls. To allow for fish of varying length the apparatus indicated generally at 88, Fig. 5, may be adjusted bodily to and from the drum 4 by a number of cams 100 moved to a position 108 according to the length of the fish as described in Specification 676,814. The apparatus may also be used in machines where the fish travel in a vertical circle or in a straight line and the fish may be back or belly uppermost.

[Also in Group XXVIII] A rotor B comprising nine sets of three cylinders each, Fig. 5, is driven by a shaft 60 through a hollow shaft 63 and an Oldham coupling 72 about a pintle A having inlet 3 and outlet 4 and secured at the left hand end only to a casting 1. A track ring D comprises a cylindrical member 20, and end members 21, Fig. 5, each carrying the inner member of a bearing 24. The outer members of the bearing 24 are carried by a support ring E, and D and E are held together as a unit for movement axially of the pintle, or tilting movement with respect to the casing 2, by end rings 23. The space between the rotor B and track ring D is sealed at the left-hand end by a pair of ring-shaped elements surrounding the pintle: 37, Fig. 8, abutting against an inward extension 40 of the casing 2, and 38, having a radial portion 42 which may slide on the member 37 and an axial portion in contact with an end member 21 of the track ring D, Fig. 5. Grooves 50 in the portion 42 permit escape of oil from around the pintle into the space between the rotor and the track ring. The elements 37, 38 are urged to the left by the rotor B, Fig. 8, which is in turn urged by a spring 65, Fig. 5, acting between the casing 2 and the right-hand end of the hollow shaft 63. Sealing rings 41, Fig. 8, and 43, Fig. 5, are provided. The space is sealed at. the right-hand end by a washer 95, Figs. 5 and 9, fitted within the bearing 24 and against the end member 21, an unattached ring washer 96, and an anglesectioned ring 97 secured to the web portion of the rotor H of a centrifugal scavenger pump. A sealing ring 100 is pressed in position between rings 97 and 96 so that 96 rotates with the pump rotor. The ring 96 is also held against washer 95 by an annular corrugated spring 102 but washer 95 may slide radially with respect to ring 96. The ring 96 may also come away slightly from the rotor H. The rotor H is driven by a pin 81 through the hollow shaft 63. In operation leakage oil is drawn from the space between rotor B and track ring D into the pump rotor H through holes 83, and oil from the bottom of the easing 2 through an inlet 87. It is expelled through radial apertures 85 in the rotor H, passage 89, space 90 and passage 91 to a spring-controlled outlet valve 92. Confining the leakage oil in the space around the pump rotor where it may flow through passages 83 into the scavenger rotor H keeps the scavenger pump primed at all times, thus maintaining suction in passage 87 and preventing undue accumulation of oil in the main pump housing. Tilting of the rotor B as a result of deflection of the free end of the pintle A during operation is permitted by the sealing arrangements described and by sliding at the arcuate interface 130, Fig. 5; between two members 128, 129 forming the lower element of a fulcrum F for the support ring E. Specification 730,086, [Group XXVIII], is referred to.

Abstract: 1418614 Sonar systems RAYTHEON CO 14 Jan 1974 [15 Jan 1973] 01579/74 Heading H4D In a scanning sonar system two acoustic radiation patterns respectively of a first and a second frequency are transmitted into a medium at sufficient intensity to provide, by non-linear interaction in a region common to the two respective main-lobes of the patterns, radiation of a third frequency whereas the side-lobes of the first frequency are directed to ensonify regions other than those ensonified by the side-lobes of the second frequency. Provision is made for altering the direction of each main-lobe while preserving both the common-region ensonification by the main-lobes and the non-commonregion ensonification by the side-lobes. The Fig. 2 embodiment includes oscillator 56, signal generator 54 and mixer 58 for providing transmission frequencies F 2  and F 1 +F 2 , where F 1  (#F 2 ) is a pulsed frequency sweep. After clipping at 64, 66, these frequencies are chopped at 68, 70 to give pulse trains which are fed through shift registers 72, 74 having multiple outputs which provide selectable delays. The delayed signals are fed via switches 84, 88 to individual transducers in a phased array 22, the switches being controlled by a computer 76 to select the delays appropriate for any given transmission direction. The frequency F 2  is transmitted by transducers A 1  - An in the array; the frequency F 1  + F 2  by transducers B 1  - B n . The A and B transducers are randomly interspersed. Echo signals at the difference frequency F 1  (i.e. the above-mentioned third frequency) are received by hydrophone 40 and fed to a CRO display 118, or to earphones or (to enhance the signal-to-noise ratio) are digitally correlated at 120 with a replica of the F 1  signal from generator 54 prior to display at 118. A ship's gyro 82 is linked to the computer 76 to provide stabilization of the transmission direction against pitch and roll of the ship. In a modification (Fig. 4, not shown), each transducer in array 22 is energized by both the frequency F 2  and the frequency F 1 +F 2 .
