Title: Improvements in, or relating to, the decarburisation of iron or iron alloy castings
IPC: C21D3/04
Filed: 1946-01-23
Abstract: Iron or iron alloy castings are decarburized by heating them to 850 to 1100 DEG C. in a gas-tight chamber which is initially filled with air, the products of reaction between the carbon of the castings and the air being circulated over heated iron oxide or other metallic oxide having an oxygen dissociation pressure similar to that of iron oxide, whereby part of the CO in the products of combustion is converted to CO2 and the resulting atmosphere maintained decarburizing and non-oxidizing to the castings is recirculated over the castings.  Iron ore may be spread on the furnace floor and the castings placed on trays above it, the atmosphere being circulated by a fan.  The regeneration of the atmosphere may be carried out in a separate chamber heated to the treatment temperature and the pipes carrying the gases may be lagged.  Two or more furnaces may be connected in parallel in one circular system.  Specifications 234,434, 239,716, [both in Class 72], 564,252, 571,245 and 585,921 are referred to.
Patent GB-933372-A (GB)
Title: Improvements in or relating to anti-theft lock device
IPC: B60R25/021
Filed: 1961-01-19
Abstract: 933,372. Key locks. A. NEIMAN. Jan. 19, 1961 [Jan. 23, 1960], No. 2229/61. Class 44. [Also in Group XXXI] An anti-theft lock device for vehicles comprises a body 1, a key-actuated lock 8 in the body controlling the opening and closing of electrical circuits and the displacement of a spring-loaded bolt 6 associated with a box staple 3 carried by a control member 2, e.g. the steering column of the vehicle through the medium of a follower 9 which extends into an aperture 10 in the bolt, the follower carrying, in the aperture 10, a slide member 11 movable in a direction at right angles to its axis of rotation by the follower, the slide member being formed with cam faces 12, 12<SP>1</SP> for causing its sliding movement by engaging the faces of the aperture 10, the slide member carrying a spring-loaded catch 13 which protrudes from its upper face and which is adapted in one position of the slide member to engage the key tip and hold the bolt against movement. The follower 9 is connected to the lock 8, which is a cylinder lock, so that rotation of the lock from its locking position rotates the follower to retract the bolt by engagement of its face 9a with one face of the aperture 10. The rotation of the follower also causes the slide member to be retracted into the aperture 10. This movement of the slide member causes the spring-loaded catch 13 to be retracted by contact with one side of the tip of the key which protrudes into the follower since the surface 14 of the catch in contact with the key is bevelled. The movement of the slide member moves the catch to the opposite side of the key. When the lock is restored to its locking position the catch 13 cannot move back to its original position since its non-bevelled face engages the key; thus the slide member 11 cannot move back to its original position but remains retracted in the follower and one end by engagement with one face of the bolt aperture 10 holds the bolt in its retracted position. When the key is removed the bolt, under the influence of its spring 22, can move to its locking position. A second spring-loaded catch 15 is also carried by the slide member and this protrudes from the opposite face of the catch 13. The catch 15 engages a V-groove in the housing of the device and prevents movement of the follower 9 except by the key. The electrical circuits are controlled by a switch 21 which is connected to the follower 9. The bolt is in two parts 6a, 6b with a spring 19 between them so that if the key is removed before the box staple hole is aligned with the bolt end, the portion 6a can move to allow the catch 15 to engage the V-groove so that the follower 9 is held in position by the catch 15.

Abstract: 450,770. Drum brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, D. T., Brock House, Langham Street, London. Jan. 23, 1935, No. 2288. [Class 103 (i)] A drum brake comprises main braking means adapted to be applied by a servo-shoe through a wedge actuated by a rotatable cam connected to the servo-shoe. The wedge member 22 disposed between rollers 25 on the main brake shoes 11, 12 rests by a roller 21 on a cam 19 formed on a sleeve 16 freely mounted coaxial with the brake drum. The sleeve has an arm 17 that carries a servo-shoe 18. The member 22 is guided by a pin. When the shoe 18 is applied to the drum by means not shown, the wedge is forced between the ends of the shoes 11, 12 by the turning of the cam 16. The slope of the cam may be such as to give different braking characteristics in the two directions of rotation of the drum. By the provision of a pair of pins the wedge may be constrained to move in a straight path and by sloping the two sides of the wedge differently, different pressures can be applied to the two shoes. The wedge member 22 may be formed on an arm 32, Fig. 3, pivoted at 33 and resting upon the cam 19. The wedge may be arranged to actuate only one shoe ; in this case the two faces of the wedge may engage rollers on the shoe end and on a fixed pivot respectively. The wedge may be operated independently of the cam and servo-shoe such as by linkage connected directly to a hand lever.

Title: Improvements in liquid filters
IPC: F16N39/06
Filed: 1944-02-08
Abstract: 574,614. Filters. KENT, A. W., and BRITISH FILTERS, Ltd. Feb. 8, 1944, No. 2333. [Class 46] [Also in Group XXXIV] In an arrangement for filtering lubricating oil or other liquids in which the liquid is circulated so that part of it is by-passed and filtered, the flow through the filter is controlled by a valve which is automatically adjusted by temperature-responsive or pressure-responsive means subject to the temperature or pressure of the liquid, whereby the rate of flow through the filter is reduced on rise of temperature or reduction of pressure of the liquid. As shown in Fig. 2, a chamber 2 near the outlet from an oil filter contains a bi-metallic strip 7 carrying a needle valve 9. The valve is positioned near to a restricted passage 4. With the oil at a low temperature the passage 4 is fully open permitting the oil to flow readily, but as the temperature increases the valve 9 moves towards the passage 4 so: that the flow of oil becomes more and more restricted. In a modification shown in Fig. 3, a chamber 10, with an inlet 11 adapted to be connected to-an oil filter, is provided with a capsule 13 carrying a needle valve 14. The valve projects into a vertical passage, 12. The capsule may be filled with gas or liquid and in addition or alternatively may have a spring 15. In the case of the capsule being filled with gas the position of the valve is determined by the pressure inside and outside the capsule. Instead of a capsule a piston inside a cylinder may be employed, the piston controlling the needle valve.
