Title: Improvements in or relating to door fastening devices
Inventor: HABGOOD GORDON ALFRED
IPC: E05B65/26
Filed: 1961-12-29
Abstract: 1,031,564. Latch fastenings. WILMOTBREEDEN Ltd. Dec. 28, 1962 [Dec. 29, 1961], No. 46557/61. Heading E2A. A releasable door fastening device comprises releasing means embodying a contactor lever 8 formed in two portions 9, 10 mounted on a common pivot 12 and respectively arranged for engagement by a release member and to act on an internal element 7 which must be moved to release the device, one of the portions 10 being slidable on the pivot from a normal position in which the portions engage and turn together to release the device to an inoperative position in which the portions can turn independently on the pivot and locking means 17 arranged to move the portion 10 between said positions. The pivot 12 is mounted on a back plate 1 which is fixable to the edge of a door and the internal element 7, which is a cam plate, is fixed to a spindle 6 which passes through a bearing in the back plate 1 and to its outer end is fixed a cam (not shown) which serves as a bolt for engagement with a keeper. When the portion 10 of the contractor lever is in its lowermost position one of its limbs 10b engages an upwardly directed limb 9b of the portion 9 so that when the portion 10 is moved by the release member (not shown), which is a push button, the portion 9 engages a limb of the cam plate 7 to turn the latter so that the cam is released from the keeper. The locking means 17 is a lever which is pivoted on the back plate 1 and which is connected to the portion 10 by a pin and slot connection at one end and at its other end to a link 19 connected to a sill control member 20 projecting from the inner door sill. Depression of the member 20 turns the lever 17 and this moves the portion 10 upwardly so that its limb 10b no longer engages the limb 9b of the portion 9, hence depression of the push button is then ineffective to release the cam 4 from the keeper. The push button has an eccentric which engages within a recess 13 of the contractor limb 10b and this eccentric is connected to a cylinder type locking mechanism fitted into the push button and when the locking mechanism is rotated the eccentric raises the portion 10 to the position in which it no longer moves the portion 9 so that in this position also the cam cannot be disengaged from the keeper. The other limb 10a of the contactor portion 10 has an abutment 27 which engages the limb 11 of the cam plate 7 should the door be slammed with the portion 10 in its inoperative position; this prevents a driver inadvertently locking himself out of a vehicle. The door can be locked without the use of a key by first depressing the push button and then slamming the door; this ensures that the abutment 27 is clear of the cam plate 7 so that the portion 10 is not displaced to its normal position when the door is slammed. The cam plate 7 has a limb 33 which is engageable by a limb of a bell crank lever which is connected to an internal handle so that the cam can be released from inside the vehicle.

The members 10, 11 of a vehicle suspension arm are connected to a vehicle superstructure by resiliently bushed pivots 13, 14 with non- coincident axes and to one another by resilient bush 22, at least two of the pivot axes passing through or near a common point. Support member 11 is pivoted to wheel carrying link 10 and the point of intersection of the axes may lie in pivot 13 or 14 (Fig. 4) or in neither pivot (Fig. 3). In Fig. 4 link 10 is torsionally and flexurally resilient and of undulating crosssection (Fig. 7) and carries a housing 25 for the bearing for a swing axle 27. In a modification (Fig. 8, not shown) the axis of pivot 13 is perpendicular to link 10. To adjust one link member relative to the other and hence wheel caster, camber or toe-in pivot 22 may include an adjustable eccentric.

Abstract: 1,191,375. Screw and nut gearing. FRIEDRICH DECKEL PRAZISIONS MECHANIK & MASCHINENBAU. 9 Oct., 1968 [23 Oct., 1967], No. 47957/68. Heading F2Q. Reverse rotation of a lead screw 16 in a fixed ball-nut 18 to lower a machine tool knee 10 is braked by a slip coupling 38 mounted on the lead screw driving shaft 24 and connected to the non-rotary knee by a one-way jamming roller clutch 32. For normal reverse rotation, the friction force of slip coupling 38 must be overcome. The torque at which the coupling 38 will slip depends on the thrust transmitted by bevel gears 20, 22 on the screw and shaft 24 respectively, and thus depends on load. In Fig. 2 (not shown), an additional spring-loaded slip-coupling (44) is mounted in parallel with coupling 38 to increase the slipping torque by a constant amount dependent on the springs but not the load.

Title: Method of making magnetic recordings which cannot be altered without it being noticed and magnetic recording media
IPC: G11B5/70
Filed: 1973-10-18
Abstract: 1439213 Magnetic recording BASF AG 18 Oct 1973 [20 Oct 1972] 48570/73 Heading G5R To make a magnetic recording which cannot be altered without it being noticed, a recording medium is used which contains exchangeanisotropic magnetizable material, comprising a ferri- or ferro-magnetic component having a Curie temperature T c  to which there is coupled an antiferromagnetic component in respect of which, below a predetermined temperature T s  lower than the NÚel temperature of the antiferromagnetic component, the critical magnetic field H sm  needed for the production of any magnetization structure leading to the irreversible rotation of the antiferromagnetic axis exceeds that obtainable in magnetic recording equipment so that the magnetization structures capable of being produced on the medium in fields smaller than H sm  vanish partly or completely after the field producing them has been removed, and either recording is effected while the medium is maintained above a temperature T AFS  (defined below) but below T c , or recording is effected below T AFS  and the medium is subsequently heated to above T AFS , and in either ease the medium is then cooled to below T s  and is subsequently provided with an indicator capable of irreversibly indicating if the medium has been reheated to or above temperature Ts. Temperature T APS , which is not higher than the NÚel temperature T N , is that temperature at or above which the antiferromagnetic axis may undergo irreversible rotation in an applied field or even as a result of the remanent magnetization having been produced below T s . The recording medium may be a tape, film, disc or card. The signals recorded by the above method cannot be completely removed by erasing operations effected at below T s  and such operations carried out above T s  will activate the indicator. The indicator may produce a colour change or undergo a physical reaction, e.g. melting, and may be applied as a stripe or coating on the side of the medium carrying the magnetic coating. The beginning and end of the recording may also be masked physically or chemically as a safeguard against editing. A control signal may also be recorded on the medium as an aid to the detection of editing. The magnetizable material preferably has a NÚel temperature of 40‹ to 500‹ C., particularly 65‹ to 300‹ C., and may comprise a CO x Ni (1-x)  alloy for the ferro- or ferrimagnetic part and a (CoO) x (NiO) (1-x)  alloy for the antiferrognetic part, where x is between 0 and 1, preferably 0À4 to 0À9. The material is preferably in the form of small particles having longest axes of 0À01 Á to 5 Á length and dispersed in a polymeric binder. Alternatively a coherent magnetizable film of 0À1 to 1 Á thickness may be applied to a base.

IPC: H01F10/00
Filed: 1963-12-13
Abstract: A magnetic storage device comprises two superimposed layers of material, one of which is magnetic, with portions of the two layers alloyed or reacted together to form non-magnetic portions separating discrete areas of the magnetic layer.  The magnetic layer may be Ni-Fe (81%, 19%) vapour deposited to a thickness of 500-1000<\>rA, and the other layer may be chromium 200-1000<\>rA thick.  An alloy of Ni-Fe-Cr with only 20-30% Cr has a Curie point below room temperature and lines of this alloy are formed by localized heating by electron beams moved in a grid pattern. Heating for 1 milli-second is sufficient.  The electron gun and scanning equipment may be in the vessel in which the layers are deposited. The substrate is polished metal such as Ag, Cu, Al, or glass or plastic with a 1 micron layer of SiO.  The layers may alternatively be applied by cathode sputtering, electrodeposition or chemical deposition.  Conducting strips may be formed on the device by depositing copper through a mask, or by coating with copper and then etching.  Magnesium fluoride or copper may be used in place of chromium.  On heating fluorine is given off which reacts with the nickel and iron.  A layer of SiO may also be formed over the Cr layer prior to applying the Cu coating.
