Title: Improvements in or relating to mechanical stokers
IPC: F23K3/06
Filed: 1950-12-22
Abstract: 692,646. Mechanical stokers. BABCOCK & WILCOX, Ltd. Dec. 22, 1950 [Dec. 27, 1949], No. 31211/50. Addition to 692,629. Class 51(i) In combustion apparatus of the type claimed and described in the parent Specification the feed plate is formed of a number of spaced sections, or is formed with a discharge edge of castellated, zigzag or wavy form, whereby in a direction transverse to the grate the conveying effect of the fluid discharge is repeatedly increased and decreased. In the apparatus shown fuel from the hopper 1 is fed by a feed roller 2 on to the plate 3 from whence it is blown by air issuing from nozzles 5 into the furnace chamber 6. The feed plate, Fig. 2, consists of sections respectively disposed in front of nozzles 5 and separated by equal spaces 8 unprovided with nozzles. In a modification the nozzles 5 are replaced by an air discharge slot extending over the whole width of the plate whilst in a further modification the slot is closed opposite the spaces similar to those shown at 8 in Fig. 2. In the former construction valve means may be provided in the air circuit whereby spaced sections of the slot may be wholly or partly closed. Again, the tongue like projections 3 may be formed into troughs as shown in Fig. 6. The feed plate 3 may be of perforated or sieve-like form serving as a screen. It may also be formed of relatively movable upper and lower laminae the edge of one lamina being straight whilst the edge of the other is of castellated, zig-zag or wavy form. Where nozzles similar to 5 are used each nozzle may be connected with an air supply duct provided with a valve such that air to each nozzle may be separately regulated. The conveying effect of the air delivered by the discharge means may be affected by changing the pressure of air supplied thereto. The pressure may be caused to vary cyclically.
Patent GB-1045888-A (GB)
Title: Process for the production of hydantoin derivatives
IPC: C07D235/02
Filed: 1963-08-08
Abstract: The invention comprises hydantoins of the general formula <FORM:1045888/C2/1> where n = 18, 20 or 22.  They are produced from the corresponding ketone <FORM:1045888/C2/2> e.g. cyclododecanone or cis-or trans-cyclodecene-2,3 or 7-one by addition of an alkali metal cyanide, e.g. KCN, and (1) NH4CO3, (2) NH3 and CO2 or (3) NH3 and a cyanate.  The ketones may be prepared by hydrogenation of cyclododecadiones which in turn may be prepared by oxidation of cyclodeca-1,5,9-triene and rearrangement of the epoxide so formed. The oxidation may be performed by 1 mole of performic, peracetic or perbenzoic acids, or H2O2 per double bond and an organic acid or buffer solution in a single or multiphase system. A solvent, e.g. ethyl acetate or acetone, and a temperature of 0-50 DEG  C. may be used.  Rearrangement of the epoxide occurs at 115-125 DEG  C. in the presence of 0.1-10% of a catalyst, e.g. MgI2.  The product from cis, trans, transcyclododeca-1,5,9-triene is a mixture of cis, trans- and trans, trans-cyclododeca-1,5-diene-9-one and cis, trans-cyclododeca-1,5-diene-10-one. Cis, trans-cyclododeca-1,5-diene is oxidized to cis- and trans-5,6-oxidocyclododecene which rearrange to cis- and trans-cyclododecene-5 and 6-ones.  Reaction of the ketone with KCN and NH3 may be carried out in a solvent, e.g. dioxan, MeOH, EtOH, PrOH, HOCH2CH2OH, glycerol, an alkyl ether of a polyglycol or a monoester of a polyhydric alcohol.  Water may also be present.  The reaction temperature may be 40-75 DEG  C. at atmospheric pressure or 40-150 DEG  C. at superatmospheric pressure. The resulting mixture may be neutralized with HCl after heating. In reactions (2) and (3) <FORM:1045888/C2/3> is an intermediate.  Cyclododecadiene-1,5-one is treated with KCN and NH4CO3 in Example (1) and HCN, NH3 and CO2 in an unnumbered example.

Title: Improvements relating to grabs
Inventor: CHILD ALBERT
IPC: B66C3/06
Filed: 1950-12-27
Abstract: 690,083. Grab-buckets. PRIESTMAN BROS., Ltd. Dec. 3, 1951. [Dec. 27, 1950] No. 31408/50. Class 78 (iv). In a single rope grab in which the bucket sections are opened by hand or by dumping, part of the mechanism for closing and locking the bucket sections is mounted on a cross beam on which the bucket sections are pivoted and part, a claw shaped hook and catch, on an arm pivotally mounted on members secured to the jaw supporting arms. The bucket sections 1, 2 are pivoted on pins 3 on a cross-beam 4 and are supported by arms 5 and 6 pivoted to a pin 8 and welded to the block 7 respectively. The locking mechanism comprises two hooks 22 pivoted at 23 to members 16 pivoted at 20 to arms 18 secured to the arms 6 and a catch 25 pivoted at 26 to the hook which are held engaged with a cylindrical member 39 mounted on the cross-beam. The hooks are held in engagement by an arm 29 which has a pin 30 engaging in a slot 31 in the member 16 and a roller 32 engaging tracks 33. The pin 30 is held at the end of the slot by the nose 40 of a member 41 pivoted to the member 16 and which hangs under gravity with the pin 43 engaging in the upper end of slot 44. The catch 25 has a tail 36 engaged by a weighted lever 34 which tends to disengage it but is prevented by friction between the catch and member 39. The hauling rope 12 is secured to the grab at 17 and passes round pulleys 14 on the members 16 so that when the grab is dumped the members 16 are lowered, a part 45 on member 41 strikes the member 39 and releases the pin 30 which slides along the slot 31 and releases the arm 29 restraining the hook to one side of the member 39 and the member 34 strikes the tail 36 to release the catch. When the rope is hauled in the arms 16 are raised and hooks and catch re-engage with the member 39. To release the buckets by hand a trip rope is secured to a member 48 having a weighted lever pivoted to the cross beam, a sharp pull on the trip rope causes the weighted end 49 to strike the catch and release it from the member 39.

Class 39(3) An air heater comprises a sleeve 16 which can fit over the pressure connection of a vacuum cleaner and an air exit housing 17 which is rotatable relative to the sleeve 16 to act as a switch handle and which accommodates an insulating carrier 18 of cruciform cross-section carrying a heating element in two selectively energizable sections 22 and 23 connected at their front ends to a common tapping point and at their other ends to contacts 24 which, by rotating the housing 17 relative to the sleeve 16, may co-operate with contacts 30 carried by the end face of the sleeve 16 and connected by feed wires 35 leading to a plug 39 which connects with the current supply contacts of the vacuum cleaner. An automatic switch 25, 26, 27 allows the element to be energized only when an air current of sufficient strength is flowing through the heater.
