Abstract: 731,278. Gates. CLITHEROE, J. S. July 10, 1953 [July 14, 1952], No. 17740/52. Class 45. [Also in Groups X and XXV] In a gate or door which is mounted between two posts or stiles 16, 17 and which can hinge and swing about either post or stile by means of hinge pins 20-23 on each end which can be moved into and out of engagement with cooperating hinge sockets by operating handles (one for each end of the gate or door) and having a bar 28 slidable between two positions in one of which it prevents disengagement of the hinge pins at one end of the gate or door and permits disengagement of the hinge pins at the other end 'and in the other of which it permits disengagement of the first said hinge pins and prevents disengagement of the second said hinge pins, and having stop means 30, 31 located at each side of the gate or door such that on opening the gate or door the stop means remote from the engaged hinges prevents movement of the slidable bar into a position permitting disengagement of the engaged hinges, the gate or door is provided with bell crank levers 24, 25 which constitute the operating handles, one end of each lever being pivotally connected to a vertically movable member which moves the hinge pins adjacent to it into an out of engagement with their co-operating sockets, the other end of each lever 24, 25 projecting into a slot 26, 27 located in the slidable bar 28, the slots being dimensioned and spaced so that during part of the movement of one of the bell crank levers to disengage the adjacent hinge pins the end of the lever moves freely in its associated slot and during the remainder of its movement the door is moved therewith. As shown hinge pins 20, 22 are integral with one vertically movable member and hinge pins 21, 23 with the other so that upward movement of the members disengage the pins from their sockets which are formed in lugs 18, 19 on the gate post 16 or 17. The connection of the limb of each bell crank lever with its slot is such that the limb moves freely in the slot for the first half of its travel and moves the bar during the second half of its travel ; in the central position of the bar both sets of hinged pins are engaged. The stop means 30, 31 are positioned one on each side of the gate or door. These means are each pivoted to a pivoted lever 32 or 33 and are arranged so that when the gate or door is opened the member adjacent the free edge drops by gravity or spring means into the return path of the bar 28 so that it cannot be moved sufficiently to disengage the operating hinge pins. When the gate or door is shut the lever 32 or 33 rides up a ramp surface on the adjacent top plug 18 of the gate or door and so raises the member 32 or 33 out of the path of the bar 28 to allow the hinge pins to engage the lugs to latch the gate or door.

[Also in Division C1] Seeds are mechanically sown in paper multicellular receptacles containing peat and/or bark humus, with a moisture content below the seed germination limit, and containing other additives. The receptacles are shaken to tighten up the peat litter before sowing and after sowing are wrapped and transported to the site of rearing for unwrapping and watering to start the germination. Multicellular receptacles 3, e.g. made from oblong strips of paper glued with a watersoluble glue at staggered intervals, so that they can be opened out and placed on a support (27), Fig. 4 (not shown), are conveyed under a silo 16, Fig. 2, by a pushing device 24, where they are partially filled with dried peat or a dried mixture of peat and bark humus, sand, sawdust or a litter of mineral origin. The receptacles pass on to a shaking device 18 and then on to sowing devices 19. These include a seed hopper 5, Fig. 1, and a sowing roller 6 which has holes passing one seed into each cell. The roller is rotated by a pinion 8 engaging a rack 9. A counter roller 11 prevents excess seeds leaving the seed tank. Another silo 17 tops up the cells with the litter while a brush 20 removes excess, and a pulling device 25 moves the receptacles to the discharge position 26. The cells on their supports (27) are stacked, covered by a card (28), wrapped, Fig. 4 (not shown), tied, and the packages transported to the place of rearing. Here the base sheets (27) are withdrawn and the seeds watered to start germination and dissolve the glue joining the cells. Additives added to the litter may include lime, which is added in a dissolved form, or powder.

Title: Improvements in or relating to synthetic resins and stoving enamels
IPC: C08G8/28
Filed: 1944-09-21
Abstract: Liquid phenol-formaldehyde resins for use as stoving enamels are prepared by effecting, in the presence of 0.6-1.6 per cent of alkali metal hydroxide as catalyst, slow controlled condensation under reflux and in a plurality of increasing temperature stages of a mixture of phenol and formaldehyde in approximately equimolecular proportions, the temperature and time of the latter stages being co-ordinated to obtain uniformity in the rate of reaction in the presence of water and the reaction being terminated on the formation of 18-23 per cent of water by salting out the liquid resin produced. The temperatures of the stages may be 50-55-60-80-95 DEG  C. and solid powdered sodium chloride or phosphate may be used for salting out.  For use in enamels the resin is dissolved in mixtures of solvents of wide boiling range, e.g. mixtures of butyl acetate, butyl alcohol, diacetone alcohol and ethyl lactate or of butyl alcohol, diacetone alcohol and ethylene glycol monobutyl ether.  Corrosion resistant fillers, e.g. stannic oxide, chromic oxide, barium sulphate, carbon black, titanium oxide, barium sulphate, clay, ferric oxide, lead chromate, aluminium powder, lithopone, zinc oxide, slate powder, mica may be added, also dyestuffs, e.g. Monastral Blue, Monolite Red, Monolite Yellow, Lithol Scarlet, Caledon R (blue).  In the example, the resin is prepared by refluxing phenol, formaldehyde and caustic soda in temperature stages of 55 DEG  C. for 1 1/2 hours, 55 DEG  C. for 1 hour, 60 DEG  C. for 2 hours, 80 DEG  C. for 1 hour and 90 DEG  C. until the end of the reaction, which is found by centrifuging samples of the resin to which 1 per cent sodium chloride has been added until a separation of 18-23 per cent water is shown. The resin is then salted out and run off from the aqueous layer and an enamel prepared from the liquid resin adjusted to 60 per cent solid content, titanium oxide, clay, a water-miscible solvent mixture and light mineral oil.  The enamels thus prepared are free from pin-holing.
