Title: Improvements in and relating to fish-treating machines
IPC: A22C25/08
Filed: 1939-06-14
Abstract: 518,608. Dressing fish. ATLANTIC COAST FISHERIES CO. June 14, 1939, No. 17378. Convention date, Aug. 27, 1938. [Class 28 (ii)] In a machine for scaling, heading and cleaning fish, the fish is advanced sidewise over a table 55 by the conveyer and clamp means described in Specification 518,607, and is positioned relatively to the knife by the engagement of a pectoral fin with an inclined edge 56 of the table, the fin being loosened from the body, if adhering thereto, so that it can extend beneath the table 55, by water jets 59a which are directed against\the fin and force it against an inclined plate 57 which extends beneath an opening 58 in the table 55. The opening 58 is enlarged adjacent to the jets 59a to provide clearance for receiving the fin, which is guided by the plate 57 to beneath the edge 56. The fish is held against the table 55 by presser bars 68, each mounted on. pair of links 69 which are pivoted to a bar 70. The bars 68 are held down by springs 72, the heads of the fishes being thus held down with the pectoral fins in engagement with the guide 56. The bars 68 may extend through the whole length of the machine, and more preferably to the cutting station to hold the fish during decapitation. The first bar 68 is toothed to turn the fish on its side if it has rolled out of that position. The fishes pass over wires 75 where they are subjected to the action of scales-removing jets 78, 79, which preferably act towards the heads of the fishes, although with certain kinds of fishes, the opposite arrangement may be used. A rubber or like flexible curtain extends across the wires 75 near the forward end thereof, to wipe the fishes, after they are positioned by the guide 56, to bring them into the proper positions before the clamps close to hold them for decapitation by the saw 92. The body of the fish is supported during decapitation by weighted pivoted arms 86, and the heads are engaged by a plate 110, on a spring-loaded pivoted arm 111, which tends to draw the head of the fish from its body as the saw 92 operates. A guide plate 120 is shaped to guide the heads downwardly and outwardly to the receiving-means as the fish is advanced past the saw. The removal of the heads in the manner described permits the greater part of the entrails to drop out, but if further cleaning of the belly cavities is required, this may be effected by water jets.

Abstract: 673,579. Fluid pressure jacks. GUTEHOFFNUNGSHUTTE OBERHAUSEN AKT.-GES. July 13, 1950. [July 13, 1949] No. 17589/50. Class 78 (iii). [Also in Group X] A two-part fluid pressure pit prop has an inflatable vessel 7, Fig. 1. of rubber or like material located between abutments 6, 3 on the upper and lower prop parts and a storage space 8 in the lower part from which the pressure mediutn is driven into the vessel 7. The space 8 is connected with the vessel 7 by tubes 9, 10, via a pump 11 with an adjustable stop valve. Where the pressure medium is water only, it is pumped into the vessel 7 by operating the pump 11 by means of a removable lever arm. Alternatively compressed air may be forced into the space 8 through a valve 12, thus driving the water into the vessel 7 to cause the prop head to abut against the roof, and the final loading of the prop may be produced by subsequent pumping. As another alternative compressed air only, may be used as the pressure medium. To protect the walls of the vessel 7 against abrasion on the inner walls of the prop parts, metal rings 14. Fig. 2, are vulcanized in the wall of the vessel 7 and wire rings 16 around it maintain it in folds under tension when not under pressure and ensure the abutment of the rings 14 against the inner walls of the prop parts.

Title: An improved rubber-containing composite fabric and method of and apparatus for manufacturing the same
IPC: B29D30/02
Filed: 1920-06-28
Abstract: 169,524. Sloper, T. June 28, 1920. Tyres, elastic, special apparatus for making.- In the manufacture of rubber goods comprising fabric layers, one or more of the layers are mechanically contracted before or during the shaping of the article. Preferably those layers which are subjected to most stretching in shaping are contracted most prior to shaping. Different amounts of contraction in different layers are obtained by contracting a layer; adhering a second layer to the first and contracting both together and so on for any number of layers. Fig. 2 shows a radial section through an apparatus for contracting fabric layers used in tyre covers. A fabric band 10 is placed around a cylindrical member 1 having a gauge-filled recess 3 from which air may be exhausted through a port 4. The member 1, with the band 10, is placed inside a hollow cylindrical member 2 having a concave or circumferentially corrugated inner surface 5 covered by a perforated rubber diaphragm 6. The space between the surface 5 and the diaphragm is exhausted through a port 9 so that the fabric is drawn into the position shown in Fig. 3. Rubber rings 7 at the sides of the diaphragm prevent ingress of air but allow the edges of the fabric to slide inwards. Metal rings 11, Fig. 2, are used to facilitate the insertion of the member 1 into the member 2. Rubber tubes adapted for inflation or exhaustion may be used in place of the rings 7. While the edges of the fabric are held fast to the member 1 by the exhaustion of ducts 19, air is withdrawn from port 4 and admitted at port 9 causing the fabric to be contracted on to the member 1. The vacuum thus caused in the recess 3 is maintained and the member 1 withdrawn from the member 2; a second band is placed over the band 10 and secured thereto by rubber compound with which it is coated and the member 1 is replaced in member 2 and the contracting process repeated. To consolidate the bands, they are placed while on the member 1 within a member similar to the member 2 but having an unperforated diaphragm reinforced with canvas. In a modification of the method. the first band is held by atmospheric pressure in the member 2 while the member 1 is withdrawn and a second band placed around it.

Title: Improvements in or relating to diesel engines
IPC: F02B25/00
Filed: 1930-06-06
Abstract: 355,404. Two-stroke engines. JORGENSEN, O. E., Lansdowne House, Anlaby Road, Hull. June 6, 1930, No. 17669. [Class 7 (ii).] To produce turbulence and rotation of a compressed air charge in a double acting two-stroke cycle Diesel engine, products of combustion from one combustion space are conveyed to a compressed air charge in the other combustion space, before or during the injection of fuel. In the engine shown in Fig. 1, transfer passages 3, 4, 5 between openings 6, 7 in the cylinder wall connect the combustion spaces 10, 13 above and below the piston 8. The'openings 6, 7 may be provided with nozzles. The transfer of gases is controlled by the piston 8, and turbulence and rotation of the charge is ensured by off-setting the passages 3, 4 relatively to the cylinder axis. The transferred gases are cooled by a liquid flowing through passages 23, 24 in the cylinder wall, the passage 23 surrounding a tube 15 inserted in the transfer passage 7. In a modification, cylinders are arranged in juxtaposed pairs with cranks at 180‹ and the transfer passages connect the two inner and two outer cylinder ends. In a further modification, the combustion gases may be delivered to a reservoir and thence be distributed to the cylinders by hand or governor controlled valves.

Abstract: 434,554. Echo-sounding and distancemeasuring apparatus. SUBMARINE SIGNAL CO., 160, State Street, Boston, U.S.A.- (Assignees of Turner, E. E. ; 130, Willow Street, West Roxbury, Massachusetts, U.S.A.) June 14, 1934, No. 17673. Convention date, July 13, 1933. Drawings to Specification. [Class 118 (ii)] To prevent sea noises and the like affecting echo-sounding apparatus, the receiving valve is biassed so that only sounds of an intensity greater than, or not substantially less than, the maximum intensity of the impulse having the greatest peak value received during the preceding time interval can overcome the bias and allow the indicating apparatus to function. The biassing potential is generated by the preceding impulse and is stored on a condenser in the grid circuit of the first receiving valve. To prevent directly received sound waves from disabling the apparatus, cam contacts short out the receiving transformer during the period immediately following emission, but if reflected waves reach the receiver before direct waves an extra valve is effective to open this shorting circuit. Specifications 226,489, 309,901, [both in Class 118 (ii)], and 388,567 are referred to.

Title: Improvement in regulating valve
IPC: F16K1/52
Filed: 1936-06-25
Abstract: 477,352. Manually - operated valves. JARNES, J. June 25, 1936, No. 17732. [Class 135] In a regulating valve, particularly for use with radiators, and of the kind which is opened and closed by rotation of a spindle coaxial with the valve opening, the cam surfaces are so shaped that the ratio of axial valve movement to angular movement of spindle increases continuously as the valve is opened. The surfaces may further be so shaped that the rate of increase of this ratio itself increases as the valve is opened. In the housing 1 is a screwed sleeve 5 with cam slot 12 with which engages a pin 11 projecting from the spindle 2 which is packed by a gland 8 in a sleeve 7, a depending portion 13 of which forms adjustable stops 14, 15 for the pin 11. A pointer 4 on the handle 3 works over a graduated disc 9 held by a nut 10, and a nut 6 holds the sleeve 5. By rotating the sleeve 7, it is possible to select a desired section of the curve, Fig. 3, thereby varying the total lift of the valve and the inclination of the cam surface in action. With this construction, if the disc 9 has a uniform graduation, the latter may be made to correspond with the heat emission. The stop 15 for the closed position may be dispensed with ; the stop or stops may be on the graduated disc ; the cam surface may be on the spinde, on both the spindle and housing, or may be outside the valve housing in which case the pointer or handle may serve as the opening member, and several cam surfaces may be provided.

Title: Improvements in or relating to extrusion processes
IPC: B29C48/09
Filed: 1942-12-14
Abstract: 562,771. Extruding thermosetting resins &c. CELLOMOLD, Ltd., DAVIES, D. N., and CHURCHMAN, F. H. Dec. 14, 1942, Nos. 17772/42 and 17370/43. [Class 87 (ii)] [Also in Group XXII] A method of producing curved extruded shapes from thermosetting resins and other extrudable substances which are deformable on issuing from the extrusion aperture but rapidly become rigid, comprises guiding a rigid part of the extruded material in a curved path, the rigid part acting as a lever which bends the still deformable material progressively at or near. the extrusion aperture. After the deformable material has been bent it becomes rigid and forms part of the lengthening lever which is bending the material issuing from the extrusion aperture. Fig. 1 shows an arrangement in which the rigid open end A of a tube of thermosetting material issuing from an extrusion nozzle 16 is attached to a block 20 having a plug which engages in the open end. The block carries rollers 21 which run in cam tracks 23, 35, 30 to produce, respectively, curved part BC, straight part CD and curved part DE. The block 20 may be in the form of a collar which fits over the end A. Jets of compressed air from an apertured ring 18 cool the issuing material to render it rigid. Fig. 4 shows a modification in which a clamp 45 having two hinged jaws is fixed to the end of a lever 44 pivoted at 43. The clamp rests on a wooden base 42. When a curved part H-H<1> has been extruded the clamp may be released and swung back, a further short straight length being then extruded and the curved part being in position H-H<2>, when it mav be sawn off. The arm or pivot or both may be adjustable and may be moved to vary the curvature. The material may be bent in more than one plane. Fig. 6 shows a flexible mandrel which is disposed within a tube to preclude flattening of the latter as it bends. The mandrel comprises a flexible wire rope carrying discs 71 separated by rings 72. The plates and rings are held together by a spring 75 located in a bore in a collar 73 in which one end of the rope is sweated, the other end being sweated in a small block 76.

Abstract: 725,628. Phase-shifting. METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 26, 1953 [June 27, 1952], No. 17826/53. Class 38 (2). [Also in Group XL (c)] A variable phaseshifting network, particularly applicable to the phase modulation of a carrier wave, comprises two or more similar phase-shifting circuits arranged in cascade and fed from the wave source, a control or modulating voltage being applied to vary the phase characteristic of all the circuits so as to produce a resultant phase shift which is the sum of the individual phase shifts. Fig. 4 shows a system employing two similar phase-shifting networks 4, 5, each comprising two condensers 24, 25 in series in one lead from a source feeding carrier current through the networks to a load. An inductance coil 22 shunts each pair of condensers, and a coil 23 is connected between the condenser junction and the other carrier lead. The condensers may be of the type in which the capacity varies with the applied voltage. As shown, a modulating signal applied at the terminals 34, 35 appears across each condenser, the coils 22, 23 and the carrier choke 33 having negligible impedance at the modulating frequencies. The aerial or other load is connected at the points 29, 30 and an impedance 6 matches the line to the load. In Fig. 5, the modulation signal is applied at terminals 40, 41 to coils 37, 39 arranged to vary the inductance of the series and shunt coils 22, 23 of each unit 4, 5. The positions of the coils and condensers in the networks may be interchanged; and an additional condenser 26 may be connected across the coil 22.
