Title: Improvements in fishing reels
IPC: A01K89/01
Filed: 1946-12-11
Abstract: 619,459. Fishing-reels. CORDEL, J. L. Dec. 11, 1946, No. 36615. [Class 48] [Also in Group XXXIV] In a stationary spool reel a ring shaped line guide 8 is pivoted to a flyer drum 3 so that it may be set in two or three positions relative to the d um and when in the reeling-in position the line guide is oscillated to distribute the line over the spool 6. In a reel having two guide settings (Fig. 4) the guide is carried by a spindle 15 mounted in a cross shaft 17 and oscillated by engagement with a cam 25 driven at a speed different from that of the drum. The guide is retained in the casting position, in which it is normal to the spool axis, by a catch 31 released when the d um is rotated by a cam 34. A spring 22 urges the guide to the reeling-in position (Fig. 4) where it is held by a manually releasable spring catch. A spool brake (Figs. 4 and 14) comprises a drum A on the spool shaft 7, brake blocks B, B<1> carried by the springs C pivoted at D, and a cam F controlled by a knob H. In a reel having three guide settings the guide is moved from the inoperative (Fig. 18) to the casting (Fig. 20) and from the casting to the reeling-in (Fig. 22) by depressing a control button. The button is connected by a cable 96 or other means to a pawl engaging teeth 74 on a rotatable collar 72, Fig. 15. Depression of the button rotates the collar through an angle subtended by one of the teeth 74 to move the plate 64 and its associated plunger 63 in an axial direction. During these movements the bell cranks 59, 60 open and close permitting the spindle 15 and the guide to rotate through a right angle under the action of a spring 56. To prevent accidental movement of the drum when the guide is inoperative a brake on the drum is pressed against the reel body by a projection on the spindle, Fig. 26 (not shown). To allow manual resetting of the guide it is pivoted to the spindle and spring-loaded to engage positioning grooves in a boss on the drum. In a simplified reel having two guide settings only, the teeth on the collar 72 and plate 64 are replaced by cams. As shown in Fig. 30 the flexure of the fishing rod 93 during the later stages of casting is used to actuate the guide setting mechanism and move the guide from the inoperative to the casting position.

Patent GB-815566-A (GB)
Title: Oxo process for the preparation of oxygenated organic compounds
IPC: C07C27/22
Filed: 1957-11-28
Abstract: Oxygenated organic compounds are prepared by a process comprising preheating a stream of hydrogen, carbon monoxide and a hydroformylation catalyst to a temperature between 140 DEG  and 250 DEG  C. and mixing this stream with a stream of an olefinically unsaturated organic compound preheated to the same temperature and in amount no greater than in equimolar porportion to the carbon monoxide present in the first stream, conducting the mixture through an externally cooled reactor having a length to diameter ratio of at least 2000 to 1, the reactor operating at a temperature between 140 DEG  and 250 DEG  C. and at a pressure between 200 and 1000 atmospheres at a rate such that turbulent flow conditions are achieved within the reactor and the total residence time within the reactor is not greater than 10 minutes.  Suitable olefinic hydrocarbons having not more than 5 carbon atoms and esters of olefinically unsaturated acids and alcohols having 1 to 4 carbon atoms such as ethyl acrylate, ethyl crotonate, ethyl sorbate and allyl crotonate.  For high yields it is necessary to have present in the reaction mixture about 5 to 50 per cent (by weight) of a liquid which may be a catalyst suspendant such as glycol, ether, ester, alcohol or a liquid hydrocarbon such as benzene, toluene and mineral oil; liquid olefines; or reaction products such as the crude products or the crude products after stripping off low-boiling fractions.  In some cases high efficiency is obtained in a single pass but in others it is desirable that part, at least, of the liquid products should be recycled.  Suitable catalysts are, for example, cobalt metal, cobalt oxide, cobalt carbonate, cobalt acetate, cobalt carbonyl, cobalt naphthenate, stearate and 2-ethyl hexanoate.  They may be introduced in solution in a hydrocarbon or an oxygen-containing solvent or in water.  The reactor is externally cooled, for example, by jacketing it in a vessel containing cooling fluid.  It is advantageous to maintain a nearly constant reaction temperature throughout the tube and this may be done by having the cooling zone divided into sections controlled at different temperatures. In the examples: (a) propylene is treated with carbon monoxide and hydrogen in the presence of a cobaltous acetate catalyst slurried in mineral oil or propanol, fifty per cent of the liquid products being recycled, to give butyraldehyde; (b) propylene is similarly treated without recycling any of the product; (c) ethylene is treated with carbon monoxide and hydrogen in the presence of a cobaltous acetate catalyst slurried in propanol, with and without recycle of reaction products, to give propionaldehyde; and (d) ethyl crotonate containing dissolved cobalt acetate is treated with carbon monoxide and hydrogen to give ethyl 4-formyl butyrate and delta-valero lactone.
