Title: Apparatus for detecting rubbing contact between relatively movable parts of a machine
IPC: F16J15/44
Filed: 1965-10-27
Abstract: Apparatus for detecting rubbing contact between normally separated relatively movable parts (e.g. the rotatable and stationary parts of a labyrinth gland in a steam turbine) comprises means for producing a difference of electrical potential between the two parts when they are not in contact and means which are sensitive to the magnitude of the electrical resistance between the two parts and arranged to give a signal, indication or control indicative of the separation or contact between the two parts. The rotor 1 is earthed by a brush contact 26, Fig. 2 (not shown), and two terminals 19, 20 are provided on each segment 4 of the gland. Leads 21, 22 from the terminals are carried by cables 23 to test terminals T1 . . . TN arid to contacts S1 . . . SN of a rotary switch SW, the moving contact-arm of which is connected to an oscilloscope DD provided with a first beam for displaying the amplitude proportional to the voltage between leads 21 and earth and a second beam for indicating the angular position of the rotor. The rotary switch SW may be stepped round either manually or automatically by a drive MV and, if desired, the results recorded on a film F. A multi-channel recorder may be employed for monitoring the gland segments over a long period of time.
Patent ES-340640-A1 (ES)
Title: Apparatus for pulling open the ends of tube sections of plastic material sheeting
IPC: B31B50/80
Filed: 1967-05-17
Abstract: Apparatus for pulling open the ends of tube sections 4 of plastics material sheeting which comprises two vacuum tools which revolve in opposite senses, is characterized in that the lower vacuum tool 2 has alternate crests and troughs which extend at right angles to the open edge of the tube section, the vacuum openings 10 of this tool being in the troughs and the vacuum openings 9 in the upper tool 1 being in registry with the crests in the closed position of the tools. The troughs may diminish in depth from a maximum at that side of the tool nearest the open edge of the bag section, and there may be two or more vacuum openings in each trough which may be selectively actuated as by connection to separate air lines or by valve means. Since the tube section is clamped by folding blades there is undesirable relative movement between the vacuum tools and the tube plies sucked thereagainst as opening proceeds. Further if the vacuum tools move at uniform linear velocity equal to the speed of advance of the tube sections, then there is a relative movement between the tools and the bag section as opening continues. To overcome these disadvantages the axes of rotation of the suction tools may be inclined, Figs. 7, 9 (not shown), and the tools may be driven at a non- uniform speed as through elliptical gearing, Fig. 10 (not shown).

Patent ES-359102-A1 (ES)
Title: Polyurethanes prepared from glyceride reaction products
Inventor: WOLFF P
IPC: B29C70/68
Filed: 1968-10-11
Abstract: Polyurethanes are prepared by reacting a polyisocyanate with a polyol component a major part of which comprises a reaction mixture of a hydrocarbon fatty acid glyceride and a dialkanolamine the ratio of dialkanolamine to fatty acid radicals being between 0À75 and 2À0 and in which at least half of the fatty acid of the glyceride has been converted into alkanolamide. It is preferred to incorporate a blowing agent in the reaction mixture to prepare rigid polyurethane foams. The polyol is suitably derived from a naturally occurring fat or oil and diethanolamine and is most suitable for use when a sample of the reaction mixture mixed with an equal amount of the polyisocyanate to be used in the polyurethane process provides a homogeneous mixture. Examples of preferred naturally occurring fats or oils are lard, bone grease, peanut oil, sesame oil, sunflower seed oil, olive oil, palm oil, coconut oil, corn oil, cottonseed oil, rapeseed oil, linseed oil, soybean oil, tung oil or fish oils. Polymerized drying or semidrying oils may also be used. Other polyols may be admixed with the dialkanolamide containing component. The additional polyol may be an ammonium soap of a dialkanolamine and a fatty acid which is incorporated in the polyol component by reacting the fatty acid glyceride with excess dialkanolamine and then neutralizing the unreacted dialkanolamine with a fatty acid. Other dihydroxy compounds e.g. ethylene glycol and propylene glycol may be used as the additional polyol. A preferred blowing agent is petrol ether, which may be mixed with conventional blowing agents. In a typical example soybean oil is reacted with diethanolamine to form a polyol component which is mixed with water, a silicone surfactant, dimethylcocosamine, petrol ether and a polymethylene polyphenyl isocyanate to produce a polyurethane foam.

Title: Disc mower conditioner
IPC: A01D43/10
Filed: 1970-05-30
Abstract: A combined crop mower and conditioner is disclosed which has a mower bar having at least two disc cutters and a pair of conditioning rolls behind and above the discs with the rotational axes horizontal. The discs and rolls are driven independently of the forward motion of the machine and are relatively positioned so that, in operation, cut crop is propelled by the cutter discs into the intake area of the conditioning rolls. For safety, the cutter bar and conditioning rolls are supported between end plates extending down to ground level, the axle of the machine obstructs the area below the rolls and behind the discs, and a hood, the rear portion of which is hinged to form a baffle plate, extends from above and in front of the discs to behind the rolls. This minimizes the danger from objects, such as stones, being thrown out by the discs.
