Title: Process for the production of stable dispersions
IPC: C08G18/10
Filed: 1975-05-16
Abstract: There is described a process for the in situ preparation of stable dispersions of polyurea and/or polyhydrazodicarboxamides in hydroxyl-containing polyethers. These products are prepared by reacting (1) organic polyisocyanates with (2) primary and/or secondary amino group-containing polyamines and/or hydrazines and/or hydrazides, in a high molecular weight polyether which has at least one hydroxyl group with the components (1), (2) and (3) being passed continuously into a continuous mixer at such a rate that the average residence time (dwell time) in the mixer is less than 10 minutes. The equivalent ratio of components (1) and (2) is between 0.8 and 1.05. The dispersions thus prepared are non-sedimenting and combine a relatively high solids content with a relatively low viscosity. The size of the dispersed particles is usually below 1 mu . Owing to these properties, they are suitable for preparing polyurethane foams.

Title: Brake actuators
IPC: F16D65/14
Filed: 1979-11-07
Abstract: A mechanical brake actuator comprises an output tappet (3) in screw-threaded engagement with a sleeve (7). In normal use, rotation of an operating member (17) by a rod or cable leads to axial advancement of the tappet (3) and sleeve (7) as a unit. Adjustment for wear is provided by rotating the sleeve (7) relative to the tappet (3) if, after a predetermined amount of rotation of operating member (17), the torque required to turn the sleeve (7) is below a predetermined value T. This is achieved by an adjuster comprising an input ring (25) coupled to an output member (29) by a torsion spring (28). The input ring (25) is coupled to operating member (17) by a lost motion connection (23,24) and output member (29) is coupled to sleeve (7) by a one-way clutch (30). After an amount of rotation of the operating member (17) predetermined by the lost motion connection (23,24) the operating member (17) entrains the input ring (25). Spring (28) is pre-loaded to transmit torque T without deforming and accordingly if at this point adjustment is necessary the sleeve will be rotated. If no adjustment is needed the spring (28) will wind up.

Title: Combination coupling and sheave.
IPC: F16H9/18
Filed: 1981-10-28
Abstract: A combination coupling and sheave in a variable speed belt drive in which a variable pitch sheave has a fixed flange, an axially shiftable flange and a shaft connected to the drive motor by a flexible coupling with the hubs thereof secured to the motor and sheave shaft. The inventive concept includes mounting the coupling hub on the sheave shaft in a bearing of a pillow block at the end of the shaft and connecting the fixed flange of the sheave to the hub, so that the fixed flange is driven directly by the hub rather than solely by the shaft, and the slidable flange is driven through the shaft, thus creating split power paths between the flexible coupling and the fixed flange and between the coupling and the slidable flange through the sheave shaft, thereby reducing the load on the operating parts of the sheave.

Title: Hog feeder.
IPC: A01K5/02
Filed: 1982-04-06
Abstract: A novel feeding system and feeder unit for supplying feed to hogs and like animals is disclosed. The feeding system includes a plurality of the novel feeders, and a feed conveyor adapted to deliver feed to each feeder. Each feeder comprises an immobile pan, and superstructure affixed over and to the pan. A threaded shaft is journaled so as to extend upwardly from the pan. A rotor gate is journaled over the pan and is threaded on the shaft means. Under normal conditions, the rotor gate simply turns within the pan and agitates the feed being consumed by the hogs. However, when a latch is depressed, the threaded shaft is immobilized, and rotation of the rotor gate about the immobilized shaft acts to raise and lower the rotor gate relative to the pan. This relative motion adjusts the size of at least one feed-delivery gate space defined between the rotor gate and the pan.

Patent ES-8502631-A1 (ES)
Title: Automatic dual compensation grinding wheel conditioner
IPC: B24B53/00
Filed: 1983-09-13
Abstract: A dual compensation method of surface conditioning a super-abrasive grinding wheel 17 by intermittently moving the wheel to a stationary wheel conditioner unit 20 mounted adjacent the grinding wheel and having a consumable element 47 engaged by the grinding wheel comprises the steps of grinding a predetermined number of workpieces W to establish a first predetermined depth of super-abrasive wheel wear, and periodically conditioning the wheel surface by consuming a second predetermined depth from a consumable reconditioning tool surface. A first compensation for grinding wheel wear is produced by controlling the position of the super- abrasive wheel with respect to the workpiece to maintain an apparent wheel wear depth within the range of desired workpiece tolerance. The grinding wheel is conditioned by contacting the wear surface of the super-abrasive wheel with the reconditioning tool surface and advancing it into and away from the tool surface a distance equal to the second predetermined depth each time that the wheel is reconditioned so as to assure that individual grains of the super-abrasive constituent of the wheel will extend beyond the bonding material constituent of the wheel to maintain cutting efficiency of the wheel following the reconditioning step.
