Abstract: 1,268,676. Endless conveyer transfer mechanisms. STA-HI CORP. 16 July, 1969 [26 July, 1968], No. 35750/69. Heading B8A. An outfeed conveyer mechanism 10 for receiving and conveying units such as stacks of publications (not shown) from a preceding conveyer mechanism 12, comprising a main frame 36, carrying a conveying device 28 defining a longitudinal, generally horizontal unit receiving surface forming a unit receiving station, pusher means mounted adjacent to the unit receiving surface and movable in at least one longitudinal direction, longitudinally across the receiving surface for moving units in said at least one longitudinal direction generally horizontally from the unit receiving station, which units are received from the preceding conveyer mechanism 12, and driving means 42 operably connected to said conveying device for intermittently moving at least the pusher means in the at least one longitudinal direction. As shown, the conveyer mechanism 10 is part of the stacking device described in Specification 1,203,829. The conveyer 28 comprises an endless belt 38 which is associated with an endless conveyer chain 46 carrying three pushers 48. The drive to the belt 38 and pushers 48 is from a continuously running motor 66 to two vertical shafts 42. Each of the latter drives through a clutch 62 to drive shafts at respective separate ends of the conveyer. One of the shafts 42 (on the power side of its associated clutch 62) has an electrically operated brake 68. The latter is controlled by a switch 76 (Fig. 1) and Fig. 5 (not shown) operated by a cam 72 which is driven by a chain 70 coupled to the associated shaft 42. Operation.-As each stack is deposited on the conveyer 28, the brake 68 is released and the appropriate clutch 66 is engaged (according to which direction of transfer is intended). Two of the pushers 48 are initially positioned with one on either side of the delivered stack (as shown in Fig. 3). The chain 70, cam 72, and switch 76, cause re-actuation of the brake 68 to bring the pushers 48 back into the positions shown in Fig. 3. Selection of the direction of delivery of the conveyer 28 and pushers 48, may be determined by manually operated switch means or automatically, e.g. by electronic computer, or punched tape, control. The selection may alternatively be arranged to provide delivery in alternate directions.

Title: Process for the desulphurisation of a gaseous mixture containing ammonia, hydrogen sulphide and carbon dioxide
Inventor: SCHADE HELMUT
IPC: C10K1/12
Filed: 1960-10-20
Abstract: In a process for selectively removing hydrogen sulphide in preference to carbon dioxide from a gas containing ammonia, hydrogen sulphide and carbon dioxide, the gas is scrubbed in a first stage with a circulating ammoniacal liquor containing a higher concentration of ammonia than that corresponding to the equilibrium with the ammonia content of the gas and in a second stage with gas condensate.  Liquor from the first stage is regenerated in a deacidifier and the liquor from the second stage is distilled and the vapours containing ammonia and hydrogen sulphide passed into the deacidifier.  Liquor to be regenerated in the deacidifier is divided into two portions one of which is fed to a central section of the deacidifier immediately above the point of introduction of the vapours containing ammonia and hydrogen sulphide derived from liquor from the second stage, and the other at the top of the deacidifier to scrub the vapours rising up the deacidifier, the relative size of the two portions being selected to produce a regenerated ammoniacal liquor having the desired content of ammonia.  Vapours containing unabsorbed ammonia and hydrogen sulphide passing over from the deacidifier are passed through a saturator and then for recovery of the hydrogen sulphide.  Both the liquor regenerated in the deacidifier and the gas condensate are cooled before being used in their respective stages.

Title: Hose Coupling
IPC: F16L37/12
Filed: 1968-07-30
Abstract: 1,167,680. Pipe couplings. KUPEX A.G. 30 July, 1968 [31 July, 1967], No. 36334/68. Heading F2G. A quickly-releasable hose-connector of spigot- and-socket type is secured by a series of radially-moving pawls 9 which lie in slots 6 in the socket member 2 and are spring-biased to engage a circumferential groove 40 in the outer surface of the spigot but being released by the movement of an outer sleeve 3 on the socket so that slots in its inner surface register with and allow radial movement of the pawls. The pawls are of plastic and have inclined cam surfaces 10<SP>1</SP> which facilitate entry of the spigot 1. As shown in Fig. 1, the pawl incorporates its own spring arm 15 which presses against the inside of the sleeve 3 to bias the pawl inwardly. In modifications (Figs. 5-8, not shown) the pawls have lateral supporting lugs at their top surfaces, and are loaded by separate springs. These may be leaf springs (19, 20) attached to the socket 2, or a wire ring (22) may lie in recesses (21) in the pawls, or the sleeve 3 may carry spring arms (23). In the form shown in Fig. 1 the sleeve 3 is rotatable against spring 36 to release the pawls. The sleeve is prevented from coming off the socket in an axial direction by lugs 28 engaging a shoulder on the socket. When the sleeve is turned, the pawls register with grooves 31 in the sleeve so that they can rise radially out of the spigot groove 40 to free the coupling. A detent lip 60 on the sleeve prevents this being turned when the coupling is under pressure. In a modification. Fig. 10, the sleeve 3 is axially movable instead of being rotatable. The union is for coupling a hose to a tap or appliance attached by screw thread 4. As shown in Fig. 10, the hose is clamped on to spigot 58 by a nut 55 and clamping ring 56. This clamping ring may be of the form shown in Figs. 13 and 14, having a bead 128 and a ring of inwardly directed teeth 129 for gripping the hose. As shown in Fig. 11, the bead 128 may be integral with the end 124 of the threaded sleeve on which the clamping nut 126 is threaded.
