Abstract: 260,893. James, R. W., (United States Hoffman Machinery Corporation). June 7, 1926. Ironing-machines with pressing action only.- In a garment or like press in which the head 5 is lowered by depressing a treadle 7 and in which heavy pressure is applied by a motor rotating a cam 18, there is provided a lever 45 for locking the press in closed position with either heavy or light pressure applied and which can be released by a kick-off pedal 43 but only after the heavy pressure has been released. The locking lever 45, pivoted at 47, is itself locked when heavy pressure is applied by a counterweighted lever 55 engaging a lug 54 in a rearward extension thereof. This lever is released from the lug by a collar 62 on a rod 59 which is given a sliding motion on the release of the heavy pressure by an arm 61 integral with the rocker element 15. Further movement of the rod 59 causes it to engage an abutment 63 on the locking lever 45 thereby swinging the lever to free its recessed portion 50 from a roller 51 on the treadle 7, thereby permitting the spring 20 to open the press. The motor is controlled by switches located in a casing 33 which are closed by a sliding rod 40 controlled by the operation and opened by movement of a bar 29 operated from the camshaft 19.

Title: Ratchet tensioners
IPC: F16G11/12
Filed: 1972-03-28
Abstract: 1423347 Ratchet tensioners for pallets &c. IRVIN GREAT BRITAIN Ltd 26 March 1973 [28 March 1972] 14497/72 Heading B8B A ratchet tensioner for a web or cable 2 comprises a reel 1 for winding the web 2 and a ratchet wheel 3 at each end of the reel 1 for engagement with fixed retaining pawls 4 and driving pawls 8 formed on the side arms of a bifurcated lever 7 reciprocable to drive the reel 1. The latter is mounted for rotational and translational movement in elongate slots 6 in fixed side plate 5 and the lever 7 has elongate slots 10 whereby it is rotatable and translatable relative to the reel 1, facilitating uni-directional rotation of the reel relative to the plates 5 and lever 7. The web 2 passes under a guide 17 on the tensioner whereby tension in the web tends to force the reel ratchet teeth downwardly into engagement with the retaining pawls. To release tension in the web 2, the lever 7 having reached its extreme anti-clockwise (in Fig. 2) position, with stops 13 thereon engaging a fixed heel 14, is pulled radially of the reel until the stops 13 are released from the heel 14 and the pawls 8 are disengaged from the wheels 3, whereafter the lever 7 is further rotated anti-clockwise, thereby lifting the reel clear of the fixed pawls 4, due to interengagement of cams 15, 16 on the lever 7 and the fixed plates 5. The lever 7 may be parked in its fully clockwise (in Fig. 2) position, with the web in tension, a spring catch 11a, 11b locating the lever with plates 5, and the plates 5 and lever 7 being interlocked by projections 12a, 12 on the plates and lever. The web 2 is locked on the reel 1 by passing it between and over a pair of parallel bars 1a forming the mid-portion of the reel shaft. An anchorage bar 20 is provided between the side plates 5 for the connection of a further web or cable 19 forming part of a tension strapping system, e.g. for a load on a pallet. In the embodiment of Figs. 5 to 7 (not shown), the web tension is releasable when the reciprocable lever is rotated beyond the parked position. This further rotation is facilitated by a bar slidable in the lever to engage one of two stops formed on the side plates, a further stop on the lever running along a cam formed on the side plates causing translational movement of the lever relative to the reel, and of the reel relative to the side plates, to release the reel from the retaining and driving pawls.

Patent GB-638917-A (GB)
Title: Improvements in and relating to the production of diethyl ketone
IPC: C07C45/50
Filed: 1947-06-03
Abstract: In an example for the production of diethyl ketone by reacting ethylene, carbon monoxide and hydrogen under heat and pressure in the presence of a hydrogenation catalyst (see Group IV (b)), the catalyst used is a fused cobalt catalyst containing 3 per cent by weight of copper and is prepared by reducing a mixture of cobalt oxide and copper oxide, the oxides are fused, preferably prior to reduction. The fused catalyst is then heated with hydrogen under pressure, thus forming a catalyst containing adsorbed hydrogen.ALSO:Di-ethyl ketone is obtained by heating ethylene with carbon monoxide and hydrogen at a temperature of from 50 DEG  to 350 DEG  C. and at a pressure above 300 atmospheres in the presence of a hydrogenation catalyst, the initial molar ratio of ethylene to hydrogen exceeding 1 : 1 and the initial molar ratio of CO : H2 being from 2 : 1 to 50 : 1.  The initial molar ratio of CO : ethylene is preferably 1.2 : 1 to 2.0 : 1.  The hydrogen may be preliminarily adsorbed on the catalyst and the latter then brought into contact with a mixture of carbon monoxide and ethylene.  Specified catalysts are nickel, cobalt, iron, copper, ruthenium and mixtures or compounds thereof, such as nickel carbonyl, cobalt carbonyl and hydride-carbonyls of cobalt.  These catalysts may be used in admixture or mixed with inert materials such as kieselguhr and pumice or with promoters such as ThO2 and Mn.  The reaction may be conducted batchwise or continuously, e.g. in an autoclave or tubular converter which may be lined with inert materials such as glass, porcelain or inert metals or materials of construction yielding small quantities of metallic carbonyl catalysts may be employed.  Vessels lined with silver or copper are preferred. An inert liquid, e.g. cyclohexane, xylene, methyl formate and diethyl ether, may be employed as reaction medium.  In examples: (1) ethylene, carbon monoxide and hydrogen are heated under pressure in a silver-lined shaker tube in the presence of a finely-divided, reduced, sintered cobalt oxide catalyst, the mixture is then distilled to obtain diethyl ketone; (2) a fused cobalt catalyst containing 3 per cent by weight of copper is prepared by reducing a mixture of cobalt oxide and copper oxide and the catalyst then heated with hydrogen under pressure in a copper-lined shaker tube.  The catalyst is then mixed with methyl formate and ethylene and then heated under pressure with excess carbon monoxide.  Distillation of the product yields diethyl ketone.
