IPC: A01D76/00
Filed: 1918-10-03
Abstract: 135,887. Bamford, S. B. Oct. 3, 1918. Rakes, horse. - In horse-rakes having self-acting mechanism which is brought into operation by causing pawls or the like to engage with ratchets on the hubs of the travelling wheels, special means are provided for actuating the pawls, for retaining the teeth in their raised position, for releasing the teeth at will, and for taking up wear of the brackets on which the teeth are fixed. Fig. 2 shows the invention applied to a rake in which the teeth 9 are fixed to independent brackets 8 threaded on a round bar 7 mounted in a swinging frame 6; but the invention is also applicable to rakes in which the teeth are hinged directly on the wheel axle. The pawls 18 are brought into engagement with the ratchet-wheels 4 by rocking a shaft 14 which is provided with arms 17 sliding in lugs 46 on the pawls. The shaft 14 is operated by means of a pedal 24, a push-rod 27, and a forwardly-projecting spring-controlled link 30 connected to an arm 23. The shaft 14 may be made in two pieces connected rigidly together by the arm 23. The tines may be held in their raised position by a spring- controlled or weighted catch 31 engaging with an arm 33 projecting from the swinging frame 6. The catch 31 may be raised to release the teeth by means of a lever 34 provided with an arm, link, or clutch to engage the catch, or by means of a pedal mounted on the draught frame 10 and connected by a rod to an arm mounted on the shaft 32 on which the catch 31 is pivoted. This pedal may be combined with a second pedal for lowering the catch 31, the combined pedal being held in either position by friction caused by a spring washer &c. In the modification shown in Fig. 6, the ratchets on the travelling wheels have internal teeth, and the lifting-pawls 48 are moved into engagement by adjustable rods 51 connected to arms 52 on the shaft 14 and are moved out of engagement by cams 53 fixed on the main axle 1. In another modification, the ratchet-wheels have teeth on their faces. Wear of the brackets 8, Fig. 2, is automatically taken up, and lateral play prevented, by coiled springs or spring washers situated between the end brackets 8 and the ends of the swinging frame 6. According to the Provisional Specification, clutches may be used instead of the ratchet-wheels and lifting-pawls.

Title: An improved process for the treatment of tubes of iron, steel or iron alloys
IPC: H01J37/32
Filed: 1955-06-08
Abstract: Iron, steel, or iron alloy tubes, particularly gun barrels, are treated on their internal surfaces by bombardment with ions of carbon, silicon, or hydrogen, the ions being produced by glow discharge in a gaseous atmosphere.  Nitrogen ions may also be present in the atmosphere and a gun barrel may be made the cathode, a wire passing through the bore, the anode, while a gas, e.g. a mixture of hydrogen and nitrogen, under reduced pressure, e.g. 1-10 mm. of mercury, is passed through the bore, the resulting glow discharge causing a layer of iron nitride to be produced on the internal surface of the gun barrel.  The gases may be purified before use by treatment with ferrosilicon or ferroaluminium at 600 DEG C. to 1000 DEG C.  Prior to treatment the internal surface may be bombarded by ions of a reducing gas, e.g. hydrogen.  Specification 744,753 is referred to.

Abstract: 553,113. Valves. BRITISH OXYGEN CO., Ltd., EDMONDSON, W., and JONES, W. Dec. 29, 1941, No. 16713. [Class 135] [Also in Group VI] Apparatus for the administration of inhalant gas mixtures comprising a plurality of gas conducting lines with a final stage pressure reducing and shut-off valve mechanism in each line, and relay mechanisms for controlling simultaneously the admission of the gases to the inspiratory passage is characterized in that the loading on each relay is independently adjustable by hand to permit of rendering uniform the response to a given inspiratory effort. The diaphragms of relays RO, RN are loaded by a reactance member such as a spring 33 common to both relays, the reactance being transmitted to diaphragm 18 through a bell-crank lever 34 mounted on a pivot 35 and to diaphragm 36 of relay RN through a similar lever 37 mounted on a pivot 38, the thrust from the levers being imparted through adjustable studs 39. The upper ends of the levers 34, 37 carry screwed stems 40, 46 on which are mounted riders 41, 47 bearing on a pivoted yoke 42. The yoke is mounted between the limbs of a bifurcated housing 43 for the spring 33. The housing 43 is slidably mounted in a guide tube 44 attached to brackets 45 which serve as bearings for the pivots 35, 38. The spring 33 bears on a tappet 48, which bears on a cam 49 connected to a control knob, by turning which a greater or less loading can be imposed on the diaphragms 18, 36 and consequently a higher or lower pressure must build up on the delivery side of valves VO and VN before the supply of oxygen and nitrous oxide is shut off. The oxygen valve VO comprises a relatively fixed hollow valve element 12 associated with a movable seating 13 capable of being pressed into engagement with the element 12 by means of a spring 14 housed within a cap 15. The. nitrous oxide valve VN is similarly arranged. A thrust pin 16 bears at one end against the seating 13 and at the other end contacts with a boss 17 secured to the centre of the diaphragm 18 of relay RO. When in consequence of the movement of diaphragm 18 the seating 13 is moved by the pin out of engagement with the fixed element 12, oxygen is permitted to pass into the diaphragm chamber of relay RO and leaves the chamber through an outlet conduit leading to the proportioning valve PV. Specification 501,053 is referred to.
