Abstract: 606,796. Door operating-appliances; door holders. DEHN, F. B. (National Pneumatic Co.). Oct. 16, 1944, No. 19972. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 30, 1945.] [Class 65 (i)] In connection with dooroperating means such as that described in Specification 572,249 comprising a fluid-pressure engine controlled by means adapted to be energized by manually actuable means, the arrangement being such that the engine operates to close the door when the controlling means are not energized, means are provided for holding the door open, such holding means comprising means for maintaining the controlling means energized independently of the manually actuable means and being manually releasable for closing the door. In the form described, the holding means comprise a device 54 which is fixed adjacent the door 1 and consists of a housing containing a pair of arms 59 pivotally mounted at 60 and urged together by springs 61, and a switch 58 comprising fixed and movable contacts normally held apart by spring means. A catch member 57 is so mounted on the door that when the latter is fully open, as shown in dotted lines, the triangular head of the catch enters an opening in the housing to close the switch, the catch being yieldingly retained in the housing by the spring- loaded arms. The switch is connected in parallel with a push plate-operated switch mounted on the door. "

Title: Improvements in shores for building construction
IPC: F16B7/10
Filed: 1930-07-01
Abstract: 358,009. Shoring. SYMONS, A. H., 4249, Diversey Avenue, Chicago, U.S.A. July 1, 1930, No. 19992. [Class 20 (ii).] An adjustable shore comprises upper and lower members 6, 7 respectively, the upper member being formed of laterally spaced wooden parts 8 grooved on their inner opposed faces at 10 to receive the flanges 13 of the lower T-section metal member, the outer edge of the web of which is provided with sawshaped teeth 31 adapted to be engaged by a latch 30 of a locking member 27. The locking member is formed as a tapered body with lugs at its upper and lower ends, the wedge face 41 a being also tapered across its width, and is loosely supported in a groove in a collar 21 fixed by screws 26 to the lower end of the upper shore member. Acting on the wedge face of the latch is a transverse wedge 45 disposed slightly inclined to the horizontal and at right-angles to the prop axis, springs 42 being positioned between the rear face of the wedge and an inclined face 19 on the collar to press the latch 30 into locking engagement with the teeth on the lower strut member. To disengage the prop, the wedge is tapped so that its thin end 45 contacts with the locking member and this causes an initial downward movement of the collar and top member with respect to the locking member. The prop is then removed and completely collapsed by raising the upper prop member relatively to the lower, so that interengaging locking lugs 46, 33, on the collar and locking member respectively, are disengaged and the locking member can be manipulated to release its tooth from the rack. The wedge provides a means of fine adjustment for the height of the prop. A footplate 14 with upstanding brackets 15 for attachment to the lower prop member is provided.

Title: Improvements in and relating to ships' davits
IPC: B63B23/18
Filed: 1919-08-16
Abstract: 158,290. Simpson, F., and Woods, A. T. Aug. 16, 1919. Davits.-Relates to ships' davits operated in the manner described in Specification 113,625, so that the movements of each davit are co-ordinated. The various parts of the mechanism by which the co-ordinated movements are effected are mounted in bearings supported from the ship's structure independently of the davits so that bending of the davits under load does not affect the axis of rotation of the operating gear, and. so that the davits may be readily disengaged from the gear and permitted to swing freely. Two associated davits A, A<1> mounted in ordinary bearings are rotated from worm shafts B, B<1> connected by universal joints, and supported from brackets C carrying the worm sectors E, E<1>. One of these sectors E is mounted on the davit and the other sector E<1> is connected to it by a coupling-rod F, so that whichever segment is in gear with its worm, the other is under control. The bosses of the worm segments are in halves connected together by bolts e<3> and fitting the davit loosely. Beneath the segment E is situated a collar secured to the davit and provided with tumbler pieces G normally engaging between lugs on the worm segment and maintained in place by bolts H. The withdrawal of the bolts H disengages the tumbler pieces G from the segment E and permits the davit to rotate independently of the gear. The bosses of the worm segments on the davits are mounted in bearings C<1> as shown, and the construction of the segment only permits engagement with the collar in predetermined positions.

Title: Method of encapsulating solid particles
IPC: B01J13/18
Filed: 1971-04-19
Abstract: 1291409 Encapsulating seeds FORENADE SUPERFOSFATFABRIKER AB 19 April 1971 [29 Jan 1.970] 20189/71 Heading A2Q [Also in Division B8] Solid particles such as seeds are encapsulated so as to lie freely within the encapsulating mantle by wet-coating the particles with a precipitant for gelatine and sodium alginate, e.g. Ca(NO 3 ) 2 , and a catalyst for the decomposition of hydrogen peroxide, e.g. MuO 2 , and dispersing the coated, particles in an aqueous gelatine/sodium alginate solution whereby the particles become coated with a precipitated gelatine/alginate layer. The coated particles are then contacted with a solution containing H 2 O 2  when oxygen is evolved on the surface of the particles causing "inflation" of the shell to give the desired product. The capsules may be washed, dried and, if desired, plasticized, e.g. by addition of glycerine or polyethylene glycol. In the specific example, carrot seeds are encapsulated.

Filed: 1946-07-10
Abstract: 621,576. Artificial joints. DESOUTTER, A. M. July 10, 1946, No. 20603. [Class 81 (ii)] A jointed artificial limb comprises two relatively movable limb members wherein opposing faces of the members are connected together solely by a block, pad or the like of rubber or similar material which is bonded or caused to adhere to the opposing faces thereby forming a resilient joint, which may flex in all directions. The opposing faces may be formed to converge about a central point of the joint and the rubber block, &c., may be shaped to conform to these faces and bonded thereto; the faces may assume the form of opposing or nesting obtuse angles in which the angle of one may be greater than the angle of the other, and the rubber block &c. may be of such shape that when its surfaces are forced to conform to the opposing surfaces and bonded thereto, either the extremities or the central portion of the block etc. will be in a state of compression. In another form, the faces may be formed of male and female portions in which the smaller and convex-faced male member is adapted to fit into the larger and concavefaced female member, the faces of these members being closest at their central positions and diverging outwards. In a modification of this form (Figs. 5 and 6) a lozenge-shape male member 24 is attached to a screw-threaded pin 25 which is inserted in a boring 20 and secured by a nut 28. The face 29 of one limb member (foot) is arcuate in formation (Fig. 6) and the face 30 of the other member (leg), formed with a cavity 18, is correspondingly shaped. A rubber block 31 shaped to fill the cavity 18 is forced therein and bonded thereto. A clearance space 32 between the limb members may be filled with a washershaped member. The male member may have convex or concave sides or it may be flat-sided. In another form, the opposing faces may converge towards each other to form a pivot point at one end of the faces. The block &c. may comprise a series of layers of rubber etc. bonded together and the faces of the block and the limb faces to which they are to be bonded may be formed with interengaging corrugations, studs, ridges or other uneven surfaces. The rubber blocks &c. may be bonded to separate attachments in turn adapted to be secured to the main limb-members. The joints may be used in artificial ankles, toes, knees, elbows or wrists.
