Title: Retractible wheel gear for caravans, trailers, mobile kiosks, and other land vehicles
IPC: B60P1/02
Filed: 1950-11-06
Abstract: 698,811. Weighing apparatus. IBBETT ENGINEERING CO., Ltd., and GREEN, M. R. Sept. 10, 1951 [Nov. 6, 1950]. No. 27073/50. Class 143. [Also in Group XXXII] In a caravan having retractable wheel gear (see Group XXXII), in which hydraulic jacks 8 are employed to raise and lower the wheels relative to the caravan chassis, a hydraulic system for controlling the jacks, includes a pressure gauge 25 which is preferably calibrated in hundred weights and pounds so that the caravan may constitute a mobile weighbridge and may if desired be suitably constructed for such purpose. As shown, the pressure gauge 25 is connected to a valve chest 17 in communication with the jacks 8 and by which pressure fluid from a hand pump 21 on the caravan, to the jacks, is controlled.

Title: Thread winding apparatus
IPC: B65H59/38
Filed: 1956-09-05
Abstract: 842,984. Beaming machines. SUCKER G.m.b.H. GEB. Sept. 5,1956 [Dec. 22,1955], No. 27119/56. Class 142(1). [Also in Groups XVI and XXXV] In a beaming machine in which a warp 1 is fed at constant speed by a roller 3, a roller 4, movable along guides 4b and loaded by fluid pressure on a piston 6 acting through cables 9c, controls the rotational speed of the beam 5 to keep the winding speed equal to the feeding speed. A drum 9, about which the cables pass, is toothed to mesh with a rack 40 carrying an electrical contact brush 41 riding on a drum 42. When the winding speed differs from the feeding speed, displacement of the roller 4 brings the brush 41 on to one or other of triangular contacts 43, 44, whereby spurts of current are fed to a motor 49 coupled to the ratio control 17 of an infinitely-variable gear 30 driving the beam 5. The roller 4 also actuates switches 45, 46 mounted on a slide so that, when the roller 4 moves away from either of the switches, the circuit to the motor 49 is broken even though the brush 41 is still wiping one of the contacts 43, 44. Alternatively, the mechanism described in Specification 840,380, which operates entirely hydraulically, may be used; it may be provided with a valve actuated by the roller 4 to reverse the hydraulic motor controlling the infinitely-variable gear if the winding speed becomes too low.
