Title: Improvements in and relating to hoisting or lowering apparatus
IPC: B66B17/32
Filed: 1935-07-27
Abstract: 460,451. Air-locks. BIRTLEY CO., Ltd. (Roberts & Schaefer Co.) July 27, 1935, No. 21407. [Class 68 (ii)] [Also in Group XXX] An air-sealing device for upcast mine shafts comprises two sets of doors at least one of which is operated, independently of a skip or like carrier by the material after it has been discharged from the skip or carrier. In the construction shown in Fig. 2 an airseal casing 1 around the shaft at the pithead is formed with a hopper 2 into which the skip 5 discharges. The hopper is provided with two weighted doors 3, 4 which are normally closed but are opened in turn by the material discharged from the skip. The hopper is preferably of equal capacity to the skip, so that the skip will normally be discharged and the door 3 closed before the door 4 opens. If both doors are open together the material in the hopper will act as a seal to prevent the passage of air. In the construction shown in Fig. 4 the hopper 12 has one door 13 only which is operated by the material as before ; the other set of doors 14 is at the top of the shaft and is operated by an electric motor 17 controlled by a switch 16<a> actuated by a ramp 15 on the skip 5. In the position shown the doors 14 are closed, and the door 13 may be safely opened by the material discharged from the skip ; after the skip has been discharged and the door 13 closes again, the skip is lowered, and the switch 16<a> is actuated again to reverse the motor 17 so that the doors 14 are opened to permit the skip to pass. The doors 14 remain open until the skip is at the top again and the switch 16<a> is actuated by the ramp. When the doors 14 are closed the top of the shaft is entirely closed by these doors and fixed plates filling spaces between the skips, where two are used, and between the skip sides and the shaft wall.

Title: Cold-hardening reaction lacquers
IPC: C09D4/06
Filed: 1962-06-05
Abstract: Cold-hardening reaction lacquers are formed from mixtures comprising (a) at least one monomeric and at least one polymeric ester of acrylic or methacrylic acid, or (b) at least one unsaturated polyester resin, if desired together with other organic compounds copolymerizable therewith, or (c) a combination of (a) and (b), and as catalyst an acyl peroxide, a monofunctional alkyl mercaptan and/or a monofunctional ester of mercapto-acetic acid in at least equimolecular quantities, and/or a polyfunctional alkyl mercaptan and/or a polyfunctional ester of mercapto-acetic acid in aliquot parts and a tertiary amine which has at least one aromatic radical bonded directly to the nitrogen atom. The preferred acyl peroxides are benzoyl and 4, 41-parachlorbenzoyl peroxides. Alkyl mercaptans and esters of mercaptoacetic acid mentioned are lauryl mercaptan, glycol dimercaptoacetate and isooctylthioglycollate. Tertiary amines mentioned are N-alkylol amines and N, N1-dialkylol amines such as diethylol-p-toluidine, diisopropylol-p-toluidine, and di-n-butylol-p-toluidine; diethylaniline, dimethyl-p-toluidine and tetramethyldiamino diphenyl methane. The reaction lacquers may also contain plasticisers, dyestuffs, fillers, paraffin, wax and U-V stabilizers. In the examples: (1) An initial polymer, prepared from pure methyl methacrylate in the presence of azodiisobutyric acid dinitrile and glycol dimercaptoacetate, was mixed with benzoyl peroxide and various amines and mercaptans were added. (2) As in (1) but all the mercaptan required in the catalyst system was added during the production of the initial polymer. In other examples the casting resins used were (a) polymethylmethacrylate in monomeric methylmethacrylate, (b) an unsaturated polyester plus styrene, (c) the initial polymer as in (1) above and a polyester resin. Finally initial polymers were prepared as in (1) above but using monomer mixtures comprising methylmethacrylate with ethyl, butyl, ethylhexyl, decyl octyl or ethyleneglycolmonoethylether acrylates or with monostyrene.

Abstract: 729,232. Haymaking machines. BAMFORDS, Ltd. July 30, 1953 [Aug. 29, 1952], No. 21700/52. Class 6 (3). The tines of a haymaking machine, such as the swath-turner described in Specification 651,995, are characterised in the provision of non-rigid connecting-means 22 between the tinecarrier 11, or a part thereon, and a point on the tine-shank 13 so that in the event of tinebreakage the broken portion is prevented from dropping off into the crop. The connection may comprise a wire link looped through an eye 23 on the tine-carrier and through a second eye 21 on a spring-clip 18 secured to the tineshank at a point beyond its most probable point of breakage, i.e. the loop 17. In a modification, the connection comprises a chain attached to an adjacent tine'on the same carrier, it being unlikely that both tines will break simultaneously. The arrangement may be also applied to the oblique tine-bar type of swathturner, the chains being then connected between the tines and the bars.

Title: Improvements in folding gin poles for oil well masts
IPC: E21B15/00
Filed: 1954-07-26
Abstract: 747,245. Raising derrick masts. MOORE CORPORATION, L. C. July 26, 1954 [Jan. 20, 1954], No. 21788/54. Class 78 (4). A gin pole 8, 13 automatically unfolds from the position shown in broken lines in Fig. 1 as it is raised by force applied to a portion of the leg 8 extending below its pivot 7. As illustrated, the unfolding is effected by tension links 23 connected between points 24 on the shoes 3 and members 19 secured to the legs 13 and embracing the legs 8. A pin-and-slot connection 20, 22 between the legs 19 and the links 23 ensures that unfolding starts only after the legs 8 have been raised to an angle of about 45 degrees. The gin pole is raised by a sling 26 secured to the lower ends of the legs 8 and passing around vertical and horizontal pulleys 27, 28 to the travelling block 5 which is drawn towards the crown by a drilling line 30 which passes over a central pulley 31 on the gin pole and so restrains its final movement into engagement with shoes 16. Movement of the gin pole past this position is prevented by engagement of the lower ends of the legs 8 with plates 37 on the shoes 3. The mast 1 is subsequently raised about pins 2 on the shoes 3 by a sling 32 which passes from the travelling block 5 over pulleys 34, 35 in the mast and over spaced pulleys 33 on the gin pole to be secured to the mast.
