Patent GB-546400-A (GB)
Abstract: 546,400. Refractory substances. SCIENTIFIC & INDUSTRIAL RESEARCH, HONORARY ADVISORY COUNCIL FOR. July 9, 1941, No. 8645. Convention date, July 20, 1940. [Class 22] Magnesia refractories for making bricks or rammed furnace linings and consisting mainly of periclase and calcium disilicate are formed by first forming a dense clinker containing calcium ferrite and subsequently treating to replace the calcium ferrite by the more refractory-magnesium ferrite. Raw materials containing magnesia, lime, silica and oxides such as those of iron, aluminium &c., are adjusted so that the lime-silica ratio is above that of calcium disilicate and the iron oxide is sufficient to form 3 to 20 per cent. of calcium ferrite or alumino-ferrite and the mixture is burned preferably with chrome ore as stabilizer. The clinker is crushed, graded to grain sizes to form a mass of high density, and mixed with ground silica which may be in the form of talc or serpentine. On burning, the ferrites react with the silica to form calcium disilicate and magnesium ferrite and aluminate. Calcium phosphate or boric acid may be added as stabilizers before the burning.
Patent GB-548465-A (GB)
Abstract: 548,465. Cash registers &c. PERCIVAL, S. (Kooperativa Forbundet Forening U. P. A.). May 22, 1941, No. 6563. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 20, 1941.] [Class 106 (i)] At least one slidable key detent is combined with a driving device preferably spring-actuated, so that after the detent has assumed the position determined by a depressed key, the detent is automatically shifted a little further in the same direction to lock the key which is not released until the end of the machine cycle. The machine has four amount key banks 1 and a special key bank 2. The amount keys 3 are locked by the usual spring-controlled detents 4. Each special key 5 carries a pin 8 co-operating with a recess 7 of a slidable detent 6. When a key 5 has been fully depressed, the detent 6 is given a slight further movement so that the pin 8 enters the recess 7. This is accomplished by a plate 10 secured to a shaft 9 and pulled by a spring 11. Normally the projection 12 engages a pin 13 on the detent 6, but upon depression of a key 5, the detent is lifted and when the key is fully depressed the pin 13 has moved past the projection 12 and a cam portion 14 of the plate 10 under influence of the spring 11 gives the detent the above slight futther movement to lack the key. An arm 19 worked by a cam, not shown, makes an up and down movement towards the end of the machine cycle and rocks a lever 16 pivoted at 15. A pin 22 on the lever engages the lug 23 and rocks the plate 10 against the influence of its spring, a second lug 24 on the plate 10 engaging the pin 25 to return the detent 6 and release the depressed key. The machine cannot start until one of the "special" keys is depressed. In the rest or Fig. 5 position, a small arm 30 moved by linkage from the shaft 9 assumes the full line position shown in Fig. 2. On depression of the start-key 38, the arm 30 is engaged by the lever 34 which is rocked against its spring 36 so that the hook 40 fails to engage the arm 41 and thus to release the lever 43 and the machine. When a key 5 has been depressed, the pin 30 has been rocked to the dotted line position and the hook 40 will release the machine on depression of the start key. The means for releasing the machine and the correction key 44 are described in Specification 545,785. When the arm 30 is in the dotted line position, the key 44 is locked on depression of the start key. At zeroizing, the differentials are locked as described in Specification 546,713. Specifications 535,265 and 545,120 also are referred to.

Abstract: 1356794 Tissue cells DEFENCE SECRETARY OF STATE FOR 21 Feb 1972 [20 Nov 1970] 55268/70 Heading C6F [Also in Division B1] A method for the production of single tissue cells from subdivided tissue (chicken embryo, rabbit, kidney, brain) suspended with concomitant red blood cells in isotonic saline solution in a container 1, Fig. 1, involves adding isotonic solution through line 4 and removing isotonic solution and red bloood cells through rotary filter 19, hollow shaft 15 and line 14 under the suction created by a peristaltic pump (not shown). Thereafter, the flow of liquid is stopped while the tissue is enzymatically disaggregated by trypsin and the single tissue cells produced are likewise removed through the filter. The filter element has a pore size which permits only particles having a mean diameter up to three times and generally about twice the diameter of red blood cells in the tissue suspension to be drawn through. The single cells are subsequently recovered from suspension by centrifugation. Preferably a collagen-digesting enzyme, such as pepsin and/or deoxyribonuclease, is used with the trypsin in order to digest the gelatinous fibrin which would otherwise obstruct the filter.
