Fig. 3b shows the draft links 14 in their middle position when the links 14 are parallel and have a small clearance with the arcuate pieces 38, 44. For weight transfer if the towed implement rises or falls relative to the tractor resulting in upward or downward load on the links 14, the automatic pressure control of the tractor causes the links 14 either to be lifted or lowered which results in the links turning about their longitudinal axes, Figs. 3c, 3a (not shown), the turning being limited by the circuate pieces 38, 44. The position of the latch 44 may be adjusted to accommodate different size links 14, and the arcuate plate 38 may be replaced by a pin (54) provided on the plates 20, 21, Fig. 3a (not shown).

Title: Crystals, in particular crystal whiskers and objects comprising such crystals
IPC: C30B11/12
Filed: 1969-04-11
Abstract: A method of manufacturing filamentary crystals, i.e., whiskers, and controlling the growth thereof in which a substrate on which are provided particles of a metal powder is heated so that the metal particles melt and form molten droplets while an atmosphere containing the substance forming the crystals is passed over the substrate. The substrate is dissolved in the metal droplets and precipitates growing a filament of whisker epitaxially. The thickness of the crystal is then controlled by adjusting the partial pressure of the metal in the atmosphere which controls the size of the droplets. In some cases, a separate source of metal for controlling the partial pressure of the metal in the atmosphere is provided.
Patent ES-372757-A1 (ES)
Title: Improvements in or relating to screw compressors
IPC: F04C29/00
Filed: 1969-10-21
Abstract: To regulate the output of a screw compressor having main and auxiliary intermeshing screwed rotors 2, 3, Figs. 1, 4 driven by a worm 4 and worm wheel 5, an axially adjustable control slide 7 has a plurality of transverse bores 17 communicating with the compressor working chamber through bores 18 and with an elongate feed opening 191 from a passage 19 supplied with lubricating oil under pressure. As the control slide 7 is adjusted rightwardly on rotation of a screwed shaft 9 either by a motor (not shown) or by means of a handwheel 10, the rightmost bore 171 is moved out of communication with the opening 191 whilst another bore 1711 is brought into communication with the opening 191 so that the zone of the rotors receiving the oil is only insignificantly displaced with decrease in compressor output. As shown, the opening 191 co-operates with five bores at any one time, the number may however be different and there may be more than one opening 191 with associated bores. In an alternative embodiment, lubricant may be admitted to an annular chamber 21, Fig. 5, in a stationary piston 20 which is supplied through bores 22, 23 by a lubricating pump (not shown). On adjustment of a control slide 71, bores 18 are brought into and out of register with the chamber 21 in a similar manner to the bores 17 with respect to the opening 191.

Title: System for offloading articles from a conveyor belt
IPC: B65G47/30
Filed: 1975-02-27
Abstract: A system for offloading bacon strips arranged side-by-side in equally spaced transverse rows on a continuously moving conveyor belt comprises a transfer station for transferring bacon strips from the conveyor belt to a serial arrangement on a second unidirectionally driven conveyor, a product grouping station for rearranging the bacon strips into groups, and a paper feed station for placing the groups on sheets of parchment paper prior to packaging. The transfer station includes a cyclically driven carriage which transfers the bacon strips in each transverse row from a carriage loading station comprising a plurality of cantilevered rotatably driven rollers contiguous to the conveyor belt to a carriage offloading station comprising a plurality of cantilevered conveyor belt assemblies. The product grouping station comprises hydraulically-actuated lifters which lift groups of the bacon strips clear of the unidirectionally driven conveyor as they proceed away from the transfer station, and then release the groups in time sequence to achieve separation on the conveyor. The transfer and product grouping stations are particularly adapted to handling thin strip-like products such as bacon slices, and employ novel control circuitry to obtain a continuous uniform operation for the loading system which does not interfere with the operation of the continuously moving conveyor belt. The system is particularly well suited for offloading fried bacon strips from the conveyor of a bacon frying oven.
