Title: Improvements in or relating to milling or other machine tool
IPC: B23C1/06
Filed: 1937-06-14
Abstract: 499,189. Change - speed gearing. KEARNEY & TRECKER CORPORATION. June 14, 1937, No. 29315/38. Convention date, June 20, 1936. Divided out of 499,137. Drawings to Specification.

Patent GB-788546-A (GB)
Title: Improvements relating to speed governors
IPC: F02D1/00
Filed: 1954-10-12
Abstract: 788,546. Fluid-pressure servomotor-control systems. GREEN, G. W. A., and FOX, G. B. Oct. 4, 1955 [Oct. 12, 1954], No. 29367/54. Class 135. A governor for a prime mover consists of means for generating a fluid flow proportional to the prime mover speed, a resistance in the path of the fluid creating a back pressure which is manually adjustable and substantially independent of the rate of flow, a second resistance in series with the first and creating a back pressure proportional to the square or higher power of the rate of flow and capable of manual adjustment whilst the prime mover is running, a connection upstream of the two resistances to a spring-loaded plunger so that the latter, which is connected to the torque controlling member of the prime mover is acted upon by the sum of the two back pressures, and means whereby the prime mover is brought to rest in the event of the governor circuit losing its working fluid. As shown, a pump 1 draws fluid from a tank 2 and delivers it under pressure to a chamber 23 containing a piston 15 loaded by a spring 17 and connected by a rod 18 to the torque controlling means of the prime mover. The fluid under pressure from the pump also passes through a conduit 4 to a spring-loaded valve member 20 which causes a substantially constant pressure to be applied in the chamber 23. The outlet from the valve member 20 leads through a conduit 24 to a valve member 6 loaded by a spring 7 which is adjustab'e by a speed-controlling member 13, and the outlet from the valve member 6 escapes to the lowpressure side of the circuit through a conduit 9 and restriction 11 which is adjusted by the member 13. A connection 25 leads from the upstream side of the restrictions constituted by the valve member 6 and restriction 11 to a chamber 16 at the right-hand side of the piston 15. To reduce the " run-up " at the maximum speed setting a flat 30 is provided on the rod 18 where it passes through a guide 26 to constitute a by-pass in parallel with the valve member 6 and restriction 11 permitting an increased flow of pressure-fluid from the chamber 16 to the lowpressure side of the circuit through a conduit 29 as the piston moves to the right in the torque increasing direction. It is stated that this bypass may be in parallel with the restriction 11 only. A manually adjustable restriction 19 is placed in parallel with the restriction 11. Where isochronous governing is required the circuit described may control an hydraulic servomechanism. Specification 571 408 is referred to.

Title: Improvements in fish-dressing machines
IPC: A22C25/08

Abstract: 443,770. Dressing fish. BAADER, R., 33, Wakenitzmauer, Lubeck, Germany. Oct. 26, 1936, No. 29641. [Class 28 (ii)] In a machine for dressing herrings or like fish, wherein the fishes are clamped by their tails to a movable support, e.g. as described in Specification 188,432, [Class 28 (ii)], which carries them past dressing tools, means are provided for transferring the fishes to another movable support which carries them past means for removing the tails. As shown, the tails of the fishes are inserted between discs 3, 4 and clamped by levers 5 rigid with levers 30 carrying rollers 31 which run in a cam track. The discs 3, 4 rotate clockwise, and when the fishes arrive at the guides 7, they have been headed, gutted and boned, and consist of two fillets united by a strip of flesh along the back. The guides 7 are carried on interconnected bell-crank levers which are constrained by a spring 27 to move towards the fish and centre it for presentation to a knife 6 which cuts the fish into two separate fillets. Two guides 8 similar to the guides 7 receive the fish from the knife 6, after which the fish is gripped adjacent to its tail by gripping-means 9, 10 rotatable about a shaft 12, the clamping levers 5 being released by the cam track. The actuation of the grippers 9, 10 is effected by a roller 19 running on a stationary cam member 14 against which it is retained by a spring 18. The gripper 9 has projections 21 which penetrate the fish and are received in recesses 22 in the gripper 10. The fish is pulled by the grippers away from the discs 3, 4, over a support 24, slotted to receive a knife 23 which cuts off the tail fins. To ensure that the cut made by the knife is straight across the fish, a pivoted finger 32 is placed in the path of the fish, and is stressed by a spring 33. The grippers 9, 10 open after the tail has been removed, and the two fillets drop into a receptacle or over a shoot. The grippers 9, 10 may be arranged for oscillation instead of rotation.

Title: Finned tubes or shafts
IPC: B23K9/032
Filed: 1971-09-13
Abstract: 1359149 Making finned tubes; coiling D C NORRIS 13 Sept 1971 [19 June 1970 22 Sept 1970] 29861/70 and 45165/70 Headings B3E and B3A Finned tubes or shafts are made by rotating two axially aligned tubes or shafts, winding a fin along one tube or shaft on to an end portion of the other, welding the fin to both shafts or tubes in the region adjacent their juxtaposed ends, and severing the fin to free the tubes or shafts. In the embodiment shown in Fig. 1, a tube T 1  is supported by a mandrel 15 and a tube T 2  is supported by the end of the mandrel and a head 20. A metal strip 5, Fig. 2, is then passed through a guide 21 and welded to the tube T 1  at its end nearest headstock 2. A helical fin is formed by rotating the mandrel and tubes T 1 , T 2  while a saddle 8 carrying the guide 21 is moved along the machine bed 1. The fin is held in place on the tube by being slightly indented in the metal of the tube as a result of the tension applied to the strip in the strip guide. Prior to the saddle 8 reaching the meeting point of the two tubes, a ram 105, actuated by a limit switch 106, moves a slide 91 towards the tube so that a guillotine 100 and welding torch 104 are adjacent the tube T 1 . A ram 108<SP>1</SP> then moves the torch to the join between the fin and the tube. A finger 110<SP>1</SP> guides the welding torch so that the fin is welded to adjacent ends of both tubes by a single line of welding. A second limit switch 107 is then actuated so that a ram 93 can be actuated to cause the guillotine 100 to sever the fin at the meeting point between the two tubes. The slide 91 and the mandrel are then retracted so that the tube T 1  can be removed while the tube T 2  is supported by support 17 and the head 20. The mandrel is returned so that its end passes into the tube T 2  after which the saddle 8 is returned to its start position, bringing with it the tube T 2 . A third tube is then placed on the end of the mandrel and the head 20 so that the above process can be repeated. In the case of oval tubes, the guide 21 is reciprocated vertically and horizontally (Figs. 11 and 12).
