Title: Improved lock
IPC: E05B37/12
Filed: 1920-03-31
Abstract: 155,216. Schmidding, W., [Firm of]. Dec. 8, 1919, [Convention date]. Addition to 141,679. Locks, permutation; bolts for.-In a modification of the lock described in the parent Specification, comprising a set of adjusting and locking wheels controlling the bolt and separated for adjustment, the separation of the locking and adjusting wheels is effected in a straight path and a plurality of groups of these, independently operable, is employed so that the number of places in the opening word or number can be increased, and thereby the security. The groups, each of which is constructed and operated as described in the parent Specification, may be independently arranged on two shafts common to the locking and adjusting wheels respectively, but to avoid excessive thickness of the lock they are preferably arranged on separate parallel shafts. Figs. 2 and 4 show two groups, the shafts 1 of the adjusting- wheels 2, 3, 4 being mounted in the lock casing and set through an internal pivoted pawl which is turned in opposite directions alternately bv a knob 61, and the slotted shafts 25 of the slotted locking-wheels 12, 13, 14 being mounted on a plate 23 having slots 50 to slide on pins 52, 53 when a prizing-tool is inserted in holes 34, 35 for separating, against the action of a spring 28, the locking wheels from the adjusting wheels when the lock is open. The locking, plate 16 carrying the locking-bars 26 engaging the slotted shafts 25 and controlled by the slotted wheels, is also slotted to slide on the pins 52, and when the wheels are positioned for opening can be withdrawn against the spring 28 by a knob 56 to release the plate from the catch 58 of the lock. Figs. 6 and 7 show a modification in which the adjustment wheels 2, 3, 4 of two groups are set from a central position through two concentric sleeves 66, 67 with operating-knobs 69, 70 ard toothed wheels 71, 72 for operating respectively and independently the left-hand set and the right-hand set. After setting of the locking-wheels 12, 13, 14 to release the slidable locking-plate 16, this can be pressed back against the spring 28 controlling both the locking-plate and the slidable plate carrying the adjusting-wheels, and the slotted bolt 79 can now be withdrawn by rotation of the central spindle 65 which carries a crank-disk 75 connected by a link 77 to the bolt, each crank-disk being locked, prior to release of the locking plate 16, by a pivoted detent 80 held in engagement by a pin 55 on the plate 16. Additional guide-pins may be provided for the sliding locking wheel plate 16 and adjusting wheel plate 23, and the plate 16 may carry additional locking projections to engage catches.

Filed: 1955-04-01
Abstract: Calcium sulphate is added to ammonium and/or alkali metal compounds and the resulting mixture is granulated, the amount of calcium sulphate present being between 10 per cent and 50 per cent by weight of the compositions.  Calcium sulphate may be incorporated as anhydrite, the hemihydrate, the dihydrate or in the form of the waste gypsum that results from the attack of sulphuric acid on phosphate rock, although such gypsum is usually acid contaminated and would have to be neutralized e.g. with chalk, before use.  It is desirable that all the solid materials employed should be ground to pass an 18 mesh British Standards sieve.  Materials mentioned in the examples include: ammonium nitrate, ammonium sulphate, ammonium nitrate sulphate, and potassium chloride.

Filed: 1953-04-09
Abstract: 736,444. Thermally-actuated valves. PARKINSON & COWAN, Ltd. April 6, 1954 [April 9, 1953], No. 9632/53. Class 135. A thermostatically-operated gas &c. valve of the kind including a differentially expanding rod 15 and tube 14 has an amplifying lever 17 interposed between a plunger 16 abutting the rod 15 and the valve stem 21. The lever is a rectangular plate bearing at its upper end in two recesses in a sleeve 19 and at its lower end against a head 20 on the valve stem 21. The bases of the two recesses are inclined so as to permit the required deflection of the lever. The valve closure member 23 coacts with a seat 22 and is held by a light spring 29 against a spider 25 so as to be self-aligning with its seat. The spider, which is engaged by a valveclosing spring 28, is threaded on the valve stem and prevented from rotating by a screw 26 so that adjustment is effected by rotation of the valve stem by a stem 31. The bore of the sleeve 19 may be broached so that the head 20 makes only a number of angularly spaced line contacts therewith to minimize impedance to movement due to dirt.

Title: Improvements in or relating to optical projection apparatus
Inventor: TAYLOR JOHN HARRY
IPC: H04N5/74
Filed: 1952-04-17
Abstract: 722,346. Optical projection apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 13, 1953 [April 17, 1952], No. 9639/52. Class 97 (1). [Also in Groups XXV and XL (b)] The apparatus is disposed in a cabinet so as to direct light towards a reflector mounted to be tilted upwardly to its operative position and also so as to be movable as a whole towards or away from the front of the cabinet. Fig. 1 shows a projection television receiver with cathode-ray tube 48, concave mirror 51, annular plane mirror 52 and Schmidt correcting plate, not shown, mounted in the aperture 50 in the upper wall 12 of the cabinet 10. The mirror 24 is secured to the lid 20 pivoted on trunnions 23 and coupled to the cabinet by links 26 secured to the lid by pins 27 and to the cabinet top by fixings 28 which may be adjustable. The trunnions 23 slide in grooves 21 as the lid is opened. The lid is held open by the device 30 shown in detail in Fig. 4. A tubular housing sliding on a fixed rod 31 comprises a central part 36 with end caps 37 and 38, the latter being coupled through a member 44 to one of the trunnions 23. A sleeve of metal braid 39 surrounds the rod 31 and is secured at its ends to washers 40, 41 urged apart by a spring 42, one washer being anchored between the end of the tube 36 and the cap 38. Owing to the action of the spring in stretching the sleeve of braid the assembly moves more readily from right to left, as shown in the drawing, than vice versa. This direction corresponds to the opening of the lid. The resistance in the opposite direction is sufficient to hold the lid open unless additional force is applied to close it, the amount of which force is adjustable by adjustment of the cap 37 on its screw-thread on the tube 36, after which it is locked by the nut 43. The top of the cabinet is recessed at 13 to accomodate controls. As shown, the projection screen is separate but may be built into the cabinet. In another embodiment the mirror is attached to the lid by a parallelogram linkage coupled to the cabinet body. The lid is pivoted on a fixed axis but as it is opened the reflector is moved forward, relatively to it, on the linkage. Specification 502,095, [Group XXV], is referred to.
