Title: Improved method of testing the resistance to wear of the material in cast-metal articles
IPC: G01N3/56
Filed: 1955-12-19
Abstract: 772,138. Hardness testing. AKTIEBOLAGET GOTAVERKEN. Dec. 19, 1955 [Dec. 22, 1954], No. 36380/55. Drawings to Specification. Class 106 (2). In abrasion testing for wear resistance of cast-metal articles a sample for testing is taken from the face subject to wear in the finished article at right angles to that face by means of a socket-drill. For example, in testing a cylinder lining, a sample core about 3 mm. in diameter is taken from the upper part of the lining just above the point reached by the upper piston. ring at the top of its stroke. The sample is subjected to any finishing treatment to which the whole is to be subjected and tested in a known machine using lubricants treated to resemble those found in the working engine.

Title: Fluid-pressure-operated-systems
Inventor: HARRIS DEREK CHARLES NOEL
IPC: B64C25/22
Filed: 1961-10-11
Abstract: 973,364. Aircraft control systems. DOWTY ROTOL Ltd. Oct. 9, 1962 [Oct. 11, 1961], No. 36538/61. Heading B7G. An aircraft fluid pressure system comprises two normally separate fluid circuits, each comprising a fluid pressure generator, a motor, a " normal " selector valve which can connect one side of the motor either to the generator or to reservoir, a normally unpressurized emergency line connecting the circuit with the other circuit, and an " emergency " selector valve which, on loss of pressure in the other circuit, can be adjusted to permit pressure fluid from its circuit to pass through the emergency line to power the motor of the other circuit. In the Figure, a pump 13 in a line 12, driven by an electric motor (not shown), delivers fluid from a tank 11 through filter 15 to an undercarriage jack 20 through a two-position valve 16 operable by a solenoid 34. The valve connects one of the jack lines 18, 23 to line 12, and the other to a return line 31 in known manner. Line 18 contains a shuttle valve 19 with piston 19a. A pressure branch line 25 and return branch line 30 including a one-way valve 33 are connected to an " emergency " valve 26 operable by hand or by a solenoid. The second circuit, with primed references, is identical. A line 28 leads from valve 26 to shuttle valve 19<SP>1</SP>, and a line 28<SP>1</SP> from valve 26<SP>1</SP> to shuttle valve 19. With valves 26, 26<SP>1</SP> in the position shown, the two circuits are separate. The valves 16, 16<SP>1</SP> are shown in the undercarriage down position, being changed over for the undercarriage up position. Should pressure fail in, say, the first circuit, valve 26<SP>1</SP> can be changed over, to make pressure fluid available from pump 13<SP>1</SP> through line 28<SP>1</SP> and shuttle valve 19 (piston 19a being displaced), to extend jack 20. Equally, jack 20<SP>1</SP> can be extended should its normal supply fail, by operation of valve 26. The connections between the two circuits may be repeated to allow emergency contraction of both jacks, and emergency operation of undercarriage bay doors. Lines 28 and 28<SP>1</SP> may be vented during normal operation to prevent thermal pressure build-up.

The handle 10 is connected by members 16, 17 to a lid 14 in the form of a flat rectangular plate having a turned-down flange 18. A pin 19 on the battery container 15 passes through the flange 18 and a screw 20 passes through the opposite end of the flange and engages the container 15. Two vertical metal strips having inward projections 21 and a central contact 22 on a metal strip 23 are provided at one end of the container, one strip being electrically connected to the strip 23 and the other one to the container. Two horizontal strips 26 having similar contacts are arranged at the opposite end of the container. A contact arm 27 mounted on but insulated from the lid 14 engages the strip 23. The lid has two eyelet openings 24, 35, one being connected to a cable 28 which also connects the arm 27 and which passes to the lamp holders via the switch 29, and the other being connected to the container. The screw terminals of the " sealed-in-steel " battery are secured in the eyelets 34, 35. Four cells in series or two parallel sets of four cells in series may be used or a single battery may be used having spring terminals which engage the contacts 21, 22, an abutment 33 being provided for positioning the battery. The lamps may be mounted on a twin holder supported across the arms of a handle mounted on the lid.

Abstract: 781,681. Hydraulic brakes. BENDIX AVIATION CORPORATION. Dec. 29, 1955 [Jan. 7, 1955], No. 37306/55. Class 103 (1). In a pneumatic servo-unit for hydraulic brakes in order to provide a better sense of " feel " in the brakes under conditions in which there is a failure of the vacuum or pneumatic pressure source and the hydraulic plunger 82 is being operated manually, it is arranged that pressure fluid within fluid chamber 105 shall be forced through a passage 130 in rod 124 into space 150 within valve member 114 and back through ports 154 and 118 into the cylinder space 74 to augment the displacement of fluid by the external part of the plunger through port 84 to the brake cylinders 88. When a certain minimum pressure has been attained sufficient to apply the brake shoes, valve member 114 is forced down against spring 190. Thus closing off the port 154 from port 118 and the hydraulic operation thus takes place in the normal manner. So long as vacuum is operative by pipe 170 in the space to the left of diaphragm 162, a stop member 158 prevents the movement of valve member 114 to its lower position. Specification 764,800 is referred to.

The preferred temperature range is 30 DEG C.-250 DEG C. and the preferred pressure range is 500-2,000 atmospheres.  Suitable catalysts are, for example, an organic peroxide such as ditertiary butyl peroxide or an azoester such as di - isopropyl - a , a 1 - azodi - isobutyrate.  Suitable alkylene oxides for use as starting materials are, for example, ethylene oxide, propylene oxide, isobutylene oxide, styrene oxide and 1,2-cyclohexene oxide.

[Also in Group XXIV] In a turbine, the turbine wheel 14 has at least one pair of holes 61 equally spaced radially inward from the ring of the turbine wheel to provide a tensile failure section and lying on either side of one of the blades 21 and a stationary ring wall 41 facing the blade tips to confine said one blade if it separates from the wheel along said section and the blades sheared off by the separated blade. The turbine drives an aircraft jet-propulsion engine through splines 25 up to starting speed and when the jet engine starts, a speed-sensing switch 23 breaks an electrical circuit 26 to a fuel and air-control device 29, whereupon an overrunning clutch or disengaging means 30 becomes operative. The starter turbine casing is provided with a stainless steel ring 41 having a shoulder 43 fitted in a recess 45 in the nozzle ring 15. The exhaust gases pass into a chamber 47 and thence into an exhaust duct (not shown). The inner wall of the chamber 47 and the ring 41 are sprayed with aluminium oxide. The turbine blades 21 are attached by welding to a wheel blank which is then machined so that the weld lies on the circumference of lowest tensile strength and four diametrically opposed pairs of holes 61 are drilled through the weld. A part of the blades is machined-off for lightness and to clear holes 63 which serve to lighten and balance the wheel. When the starter turbine overspeeds, at least one of the weakened blades will separate from the turbine wheel whereupon it will drag on the coating on the ring 41 and shear-off adjacent blades 21 which will be trapped and so shear-off the remainder of the blades.
