Title: Improvements in or relating to locks
IPC: E05B65/50
Filed: 1937-11-19
Abstract: 506,040. Locks and latches. KENNEDY, E. N. Nov. 19, 1937, No. 31819. [Class 44] In a change-key lock having locking members formed of two or more parts normally rotatable as one about the same axis as the key but capable of relative rotation, the relative angular position of the parts determines the amount of lost motion of the key before it moves the'locking members to the unlocked position. In the locking mechanism shown, described as applied to the latch mechanism described'in Specification 506,041, the locking member comprises a disc 36, Fig. 6, apertured for engagement by the key, and a ring 37, notched at 38 to co-operate with the pivoted catches, held together by an L-sectioned ring 32. The disc 36 is attached to the ring 32 by lugs 35, Fig. 8, which engage axial notches m the ring 32 and project above its surface to form abutments against which the ring 37 is pressed by spring fingers bent out of the flange of the ring 32. The locking member rotates on a bearing 39 pressed out of the wall of the lock and additional looking members may be similarly mounted on fixed plates apertured to clear the key. The key aperture 42 in the disc 36 has two edges 43, successive points of which are at decreasing distances from the axis of the disc so that the amount of lost motion of the key depends on the length of the key bit. A distance piece 21, formed with a keyhole 22, Fig. 7, carries a flange 23 having notches 24 corresponding with the notches 38 in the ring 37. When the key is inserted and turned almost 360‹ the notches are aligned in a position permitting entry of the catches, rotation of the key being then impossible until the catches are disengaged from the notches. To adjust the lock to suit another key, the ring 37 is held in the unlocked position by moving a hooked member 47, Fig. 5, into engagement with. a recess in the ring. The old key is then turned to the locked position, the new key inserted and turned to the unlocked position, and the ring 37 released. The edges 43 of the aperture in the disc 36 may be straight or curved, and smooth or stepped, and if a key with a single bit is used instead of the double-bitted key shown in Fig. 6, only one edge 43 need be provided. Circular ribs may be formed in the wall '30 and wards may project into the path of the key. Oval plates, similar to those shown in Specification 506,041, may be substituted for the notched rings 37. In a modification, applied to a night latch, a spring-influenced pawl, pivoted between two rotatable plates mounted at opposite ends of the mechanism, enters the notches when these are brought to the unlocked position. The pawl also enters a notch in a rotatable tail plate connected to the latch mechanism. Further turning of the key then withdraws the bolt. The Provisional Specification describes twopart locking members in which an inner disc has ears clinched round the inner periphery of the notched ring.

Title: Improvements in or relating to high molecular weight copolymers, more especially as lubricating oil additives
IPC: F02B3/06
Filed: 1946-10-28
Abstract: Lubricating oils have their properties such as pour point and viscosity index improved by incorporating a copolymer of a dialkyl fumarate and a vinyl ester of a fatty acid.  The alcohol of the fumaric ester is saturated and contains an average of 8-18 carbon atoms, preferably 13.5 as in the product known under the Registered Trade Mark "Lorol."  The resulting copolymer is both a pour point depressant and viscosity index improver.  Lower alcohols give copolymers which are only viscosity index improvers. The preferred vinyl ester is vinyl acetate (see Group IV (a)). They may be used in concentrations of up to 10 per cent of the oil, examples of which are paraffinic oils including diesel fuel and domestic heating oil base stocks, mineral seal oil and refined kerosene.  The copolymers may also be added to greases containing metal soaps or to paraffin wax compositions.  Other additives may also be added and include dyes, anti-oxidants, wax-phenol or wax-naphthalene condensation products, polybutene, polyacrylates, polyvinyl ethers and esters.ALSO:A dialkyl fumarate of one or more saturated alcohols having an average of 8 to 18 carbon atoms in the molecule is heated with a vinyl ester of a fatty acid in the presence of an oxygen yielding catalyst to yield a copolymer suitable as a lubricant additive. Suitable alcohols of the fumaric ester are the product obtained by hydrogenating coconut oil, octyl, decyl, octadecyl and cetyl alcohols and minor amounts of lower alcohols, e.g. hexyl and amyl alcohols.  Suitable vinyl esters are those of acetic, propionic, butyric, lauric, myristic and palmitic acids, including the vinyl ester of coconut oil acids. Polymerization may be effected at 50-125 DEG  C. in an inert atmosphere using super-atmospheric pressure or refluxing.
