Title: Improvements in machines for public works
IPC: B62D57/02
Filed: 1961-11-14
Abstract: 921,867. Earth-working machines. P. J. PINGON. Nov. 14, 1961 [Nov. 24, 1960; July 26, 1961], No. 40652/61. Class 68 (1). [Also in Groups XXX, XXXI and XXXII] The wheels 2 of a power-operated shovel bulldozer, crane or tractor are attached to the body 10 of the machine by pivoted arms 12 (Fig. 10) interconnected by toothed sectors 28 so that the wheels may be retracted by hydraulic jacks 30 whereupon the machine is supported on the ground by an H-shaped platform rotatably mounted beneath the body 10. An internal-combustion engine 16 drives the wheels 2 through a transmission system (see Group XXXI) including differential braking for steering purposes and chain drives disposed within the arms 12 and also drives a pinion engaging a crown gear on the platform 3 for rotating the body 10. To an attachment point 25 on the body 10 is fitted a crane jib or a jib carrying a shovel (Figs. 2, 3) or a bulldozer blade (Fig. 4).

Title: Improvements in or relating to remote electrical indicating devices
Inventor: HAYMAN BERNARD MAX
Filed: 1958-12-17
Abstract: 862,899. Position-indicating systems. AUTOMOTIVE PRODUCTS CO. Ltd. Dec. 17, 1959 [Dec. 17, 1958], No. 40776/58. Class 40 (1). [Also in Groups XXXIV, XXXV and XXXVI] In an indicating system of the type in which equidistant tappings 4, 5 and 6, Fig. 6, on a toroidal resistor supplied with D.C. at diametral points via sliding contacts are interconnected with the stator windings 23 of a resultant field receiver with a permanent magnet rotor, the supply circuit is completed only during the rotation of the sliding contacts in one direction. A normallyapplied brake is then removed from the receiver rotor by a solenoid 31. By this means the indicator registers the preceding signal which may represent the. travel of a brake pedal. A switch 37 may be provided whereby the transmitter is permanently supplied and the receiver rotor permanently free so as to show at all times the position of the pedal. Transmitter, Fig. 2. A rack-and-pinion 22, 20, coupled, for example, to the brake pedal, rotates a shaft 17 carrying an arm 15 projecting to a slot in one of a pair of rotating contactarms 10 and 11. Arm 10 is connected to the supply but arm 11 is insulated and receives the supply through the actuating arm 15. One edge of the slot is insulated and the other conducting with the result that the contact arm 11 is only energized when the arm 15 is driving it in one direction. Receiver, Fig. 4.-The permanent magnet rotor 25 has limited axial movement and is normally urged to the left by a spring 29 acting via solenoid plunger 32, pivoted bar 33 and operating-pin 36, in which position a brake-pad 28 secured to the rotor engages a braking surface 30 on the front cover 27. When solenoid 31 is energized the spring is compressed and the braking pressure relieved. Alternatively the braking pressure may be relieved by axial movement of the rotor due to energization of the stator or, according to the Provisional Specification, by making the solenoid act directly on pin 36.

Abstract: 936,251. Luminescent materials. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 9, 1959 [Dec. 10, 1958 (2)], No. 41942/59. Drawings to Specification. Class 39 (1). Method of making a phosphor, e.g. a calcium halo-phosphate phosphor activated by trivalent antimony and manganese, comprises preheating the starting materials at a temperature between 1000 ‹ and 1600 ‹ F. sufficient to remove undesired ingredients such as water and carbon dioxide but below that at which phosphorproducing reaction between the materials occurs and firing the materials at a temperature substantially above 1600‹ F. immediately following the pre-heating and without an intermediate cooling. There may be two pre-heating zones, one at about 1150‹ F., and the other at about 1350‹ F., a firing zone at between 1900‹ and 2150‹ F., for example at about 2050‹ F., and a final cooling zone at well below 1000‹ F. Part of the cooling zone can be kept at about 660‹ F. and the remainder at about 360‹ F. The firing can take place at two temperatures, only the second higher one of which causes the formation of the phosphor. The materials can be moved through zones heated to different temperatures, and a flow of gas inert with respect to the materials, such as nitrogen, can be maintained over them, the direction of flow being the same as that of the movement during the pre-heating and opposite to that of the movement during the firing. The starting materials can be placed in an open silica boat, on a ceramic plate on rails, to a level between two-thirds and three-quarters of the inside height of the boat. When the starting materials contain compounds of antimony and chlorine, the atmosphere of antimony chloride accumulated above the materials during the firing is kept below atmospheric pressure.
