Title: Improvements in Locks and Latches.
Inventor: SWEET ANDREW
IPC: E05B55/00
Filed: 1919-01-23
Abstract: 134,132. Sweet, A. Jan. 23, 1919. Locks, revolving - barrel. - In a revolving-barrel lock, the barrel D is locked against rotation by means of a stump N, Fig. 6, carried in a recess N<1> in the barrel and normally held in engagement with an inclined recess g in the fixed cylinder E by disks K housed in the barrel. The disks each have a keyhole L with steps L<1> for engagement with the key-bits, and true and false gatings M. In operation, the key is rotated to turn the disks, the bits engaging with selected steps L' in the different disks, and sets these with their true gratings beneath the stump N. Further rotation of the key turns the barrel D, the stump N being forced out of the recess g by the incline into the disk gatings, and operates the bolt by means of a follower on the barrel. On reversing the key, the stump is reengaged by its spring F<1>. In the form shown, the stump N is in one piece extending across all the disks, but in a modification, there is a radially-moving pin for each disk. Master-key locks.-A master-key lock is obtained by cutting a special gating in each disk to correspond with the master-key bits., all the disks in the locks having the same stepped keyhole. In one form, the revolving barrel has a bar integral with it to engage a projection on a latch bolt and lock this in the shot position. Specification 128,512 is referred to.

Title: Process for the production of non-spalling highly refractory chromite bricks
IPC: C04B35/44
Filed: 1934-01-22
Abstract: A refractory brick is made from a mixture of magnesite and chromite, in which the chromite forms a preponderating amount not exceeding 80 per cent and in which the grain sizes are adjusted so that the fine fraction below 200m  (and preferably below 100m ), the intermediate grain fraction and the coarse fraction above about 1000m  are in the ratios 20 to 40 : 15 to 25 : 35 to 65. Deviations from this rule may be made, e.g. the intermediate fraction may be selectively reduced down to complete elimination to a final ratio of fine: coarse as 20 to 40 : 80 to 60, or the upper limits of fractionation can be altered so that in an extreme case the fine fraction contains grains up to 250m  and the coarse fraction those exceeding 1300m .  The magnesite, sintered or fused, is preferably added as to its main bulk as fine fraction. Binding-agents, such as linseed oil, cellulose waste liquor, waterglass, magnesium chloride, or quick setting cement may be used during moulding.  In examples: (1) the mixture is divided into fractions up to 100m , 100 to 800m , 800 to 3000m  in the proportions 30 : 20 : 50 with a variation of one-third in either direction.  After addition of binding media if desired the mixture is moulded at 200 to 1000 kgs. per sq. cm., dried and fired at 1400 to 1600 DEG  C.; (2) a ground mixture is divided into fractions up to 100m , 100 to 1000m , and 1000 to 3000m .  The size 100 to 500m  is separated from the middle fraction and that of 1000 to 1500m  from the coarse fraction.  Specifications 271,847, [Class 22], 360,572, 364,131, and 381,981 are referred to.
