Title: Improvements in machines utilising rotary tools
IPC: B23Q11/04
Filed: 1951-02-01
Abstract: 687,616. Drilling long holes. FARMER, H. E. Feb. 1, 1951, No. 2532/51. Class 83 (iii). [Also in Group XXXVII] A drilling-machine comprises a tool carrier 12 movable to and from a workpiece, an electric motor 15 for rotating the tool, and an electronic valve 197 in circuit both with the motor and a switch controlling movement of the carrier, the valve being responsive to a predetermined torque of the tool to retract the carrier. The head 12 is mounted on guide rods 11 and carries the electric motor 15 to rotate the drill 14. The head is reciprocated by a hydraulic piston whose movements are controlled in speed and direction by a unit 28, Fig. 10. This unit contains two valves 38, 39 operated by solenoids 31, 32, and ports 44, 54, communicating respectively with the rear and front ends of the hydraulic piston. The valves are shown positioned for fast forward feed. With the valve 39 in a lowered position the fluid is exhausted through a restricted passage 57 instead of a passage 56, so causing a slow forward feed. The hydraulic operation is controlled by electric switches 60-63, Figs. 1 and 7, actuated by dogs 81 and 82 adjustably mounted on the head 12 and a dog 90 on a rod 91 also secured to the head 12. The dog 90 is frictionally mounted on the rod 91, in such a way as to hold the dog fast while the switch 63 is actuated but to allow the dog to be pushed rearwardly by a stop 97 as the drill advances. The dog 90 thus permits the drill, if it is withdrawn, to be fed forward to the position it had previously reached. In operation, a switch 113, Fig. 14, is closed to energize the solenoids 31, 32, causing the drill to be fed rapidly forward, the exhaust passage 56 being open. Movement of the drill-head 12 causes the cam 82 to allow the switch 60 to close. At the forward end of the movement the cams 81 and 90 close the switch 62 and open the switch 63 respectively. The solenoid 32 is thereby de-energized and the exhaust passage 57 is opened to slow the drill to feed-speed. If the drill torque exceeds a maximum pre-set by a potentiometer 188, the increase in voltage across a resistance 187, in parallel with the motor 15, causes the electronic valve 197 to energize a relay 149. The relay 149 closes contacts to energize the solenoid 32 and de-energize the solenoid 31. The drill is thus withdrawn at fast speed and the electronic valve is de-energized. While the drill is withdrawn it may be cleaned by a jet of fluid. During rearward movement of the head 12, the cam 81 releases the switch 61, thus energizing the solenoid 31 and returning the drill to the work at a fast speed until the cam 90, which has been moved during the drilling operation, opens the switch 63. When the hole is drilled to depth, the cam 81 closes the switch 62, which causes the solenoid 32 to be energized and the solenoid 31 to be de-energized, thus withdrawing the drill. The drill-head is stopped in its rear position by the actuation of the switch 60 by the cam 82.

Title: Improvements in the production of atmospheres for the gaseous cementation of ferrous alloys
Inventor: PALETHORPE LOUIS GEORGE WHYBRO
IPC: C23C8/22
Filed: 1954-01-29
Abstract: Gases suitable for the gaseous cementation of ferrous alloys are produced by cracking a monohydric aliphatic alcohol containing from 5-30 per cent by volume of water within a heat treatment furnace at between 700 DEG  and 950 DEG C.  The furnace is constructed of material free from iron and the liquid to be cracked is fed into the furnace by a drip-feed arrangement.  The preferred cracking liquid is iso-propyl alcohol containing 15-25 pre cent water.  A nitrogenous liquid which is fully miscible with the alcohol/water mixture may be added to the cracking liquid when carbo-nitriding is required. Concentrated ammonia solution is the preferred nitrogenous liquid and is added in such quantity as to produce 2 1/2 -7\ba1/2 per cent of ammonia in the resultant atmosphere.  Alternatively the ammonia could be added to the atmosphere in gaseous form.  In an example using isopropyl alcohol containing 25 per cent by volume of water the gas obtained had the following composition: <TABS:0748320/II/1> Specification 588,547, [Group XII], is referred to.

Abstract: 984,738. Centrifugal separators. WESTFALIA SEPARATOR A.G. Jan. 23, 1964 [Jan. 26, 1963], No. 3047/64. Heading B2P. A centrifuge for separating solid or liquid material from a liquid comprises a control chamber 11 located adjacent the drum axis, means for applying liquid to the control chamber, a conduit 12, 12a connecting the chamber 11 to the interior of a sediment chamber 1 and arranged so that displacement in the free surface of the liquid in the chamber 1, caused by the deposition of sediment therein, causes corresponding displacement of the liquid in the chamber 11, the latter displacement being used to actuate a pressure responsive device 19 to provide a signal to indicate when the sediment chamber has filled up and/or to operate a control system for commencing the discharge of the sediment from the chamber. The liquid to be treated is fed in through a pipe 4 and the clarified liquid flows from the central part 6 of the separating chamber via passages 7 into a chamber 8 where it is removed by a skimming member 9 leading into a conduit 10. The chamber 11 is connected to the chamber 1 via passages 12 and a ring passage 12a. Purified liquid constantly flows into the chamber 11 via a bore 14 communicating the passage 15 the member 9 to a passage 13 in the member 17, the passage 13 communicating via a passage 18 to the device 19. Alternatively, the member 17 may be replaced by a float, whilst passage 13 may be connected with the untreated liquid inlet pipe 4 via a bore or with an inlet for an auxiliary liquid. In operation, the levels of the free surface of the liquid in the chambers 1, 11 are at the same distance from the centrifuge axis. As soon as the separated material covers the opening 16 of the ring passage 12a, the free surface of the liquid in the chamber 11 is displaced until it reaches the passage 13 into which static pressure is thereby created opposing the flow of liquid through the bore 14. The static pressure is transmitted via the passage 18 to the device 19 which causes a valve 2 to uncover openings 3 for the discharge of the separated material.

[Also in Division B8] In a conveyer, particularly a gravity conveyer, comprising parallel rollers 20 rotatably mounted with respect to parallel side rails 10, 12, each roller comprises a hollow plastics sleeve 30 and two molded plastics end caps which have external generally cylindrical mounting surfaces engaging end openings 36, 38 formed by the sleeve bore and are journalled on support pins rotationally fast in the side rails. As shown, mounting surfaces 42 on end caps 40 comprise axially extending ribs 44, the diameter at the tips of which slightly exceeds that of the sleeve bore so that the end caps may be satisfactorily secured in the sleeve by being forced therein, although adhesive may be used. The mounting surfaces 42 terminate in outwardly extending flanges 46 locating the caps in the sleeve. The sleeve is of thermoplastic material such as polyvinylchloride. The end caps are injection moulded of acetal resin or other thermoplastic material such as P.T.F.E. or nylon. The end caps 40 comprise bearing bores 52 terminating at one end in inwardly directed flanges 56 having apertures 54. One of the pins, 60, preferably of the same material as that of the end caps, comprises a journal portion 62, an hexagonal extension 64 for engagement in an hexagonal aperture 66 in the corresponding side rail 10, and a nose 70 slotted to define resilient fingers 74, 76 which when snapped through the apertures 54 retain, by shoulders 78 thereon, the pin in the end cap. The other pin, 80, is similar to the pin 60 but its journal portion 82 is shorter and a spring 100 is interposed between this portion and the end cap flange 56 to bias the pin outwardly of the cap. To assemble the roller in the side rails, the pin 80 is forced inwardly against the spring 100, the hexagonal extension of the pin 60 is inserted in the aperture 66 of the rail 10, and, when the roller is suitably aligned, the pin 80 is released for its hexagonal extension to engage the corresponding aperture in the rail 12. In Fig. 4 (not shown), the end caps are adhesively secured in the sleeve 30, and the support pins are not axially retained in the end caps but are flanged and bolted to the side rails.
