Abstract: 136,049. Caterpillar Tractors, Ltd., (Holt Manufacturing Co.). March 10, 1919. Endless-track vehicles. -In an endless - track vehicle, one end of the main frame is spring supported from the roller carrying trucks through a bell-crank lever which also serves to tension the chain track, but in such a way as to allow yield between the end sprockets and thus prevent breakage of the track in the event of the accumulation of mud and dirt between the sprockets and track. In the two-track vehicle shown in side elevation in Fig. 1, and in the detailed view, Fig. 3, the bell-crank levers 26 are pivoted at opposite ends of a transverse shaft 28 which is supported in bearings on the main frame, and also carries the forward ends of the thrust rods 30 for the driving sprockets. The two trucks 14 are both pivoted to a transverse shaft 20, and the bearings for this shaft are engaged on one side, which is preferably flat, by the vertical arm 25 of the bell-crank lever. Between the horizontal arm 27 of the lever and the truck 14 is interposed a helical spring enclosed in a cylindrical casing 32'. This spring thus supports one end of the main frame and also applies tension to the track. Pins 25' on the bearing of the shaft 20 engage slots in the vertical arms 25 of the bellcrank lever. The other end of the main frame is supported from the trucks by a transverse equalizer bar or spring 19.

The framework is detachably fitted in sockets in the end brackets 1 and has an upper adjustable portion with depending legs 30 slidable within the members 25. As shown in Figs. 4, 5 a spring-urged ball 33 and a pin 34 urged by a cam 37 against the action of a spring 35 enter selected holes 31 in the members 30 to position the adjustable portion. When the device is to be used as an electric fire the framework is removed and the heater rotated and locked in the desired position. The device may be used as a table by securing a panel in a horizontal position to the framework a turn button being engaged beneath the top rails 28 or as a firescreen by attaching the panel to hang down from a rail 28 by a hook provided on the undersurface of the panel. In the Provisional Specification the attachment of the panel to the framework is by spring clips.

Patent GB-382843-A (GB)
Title: Improvements in or relating to bearings
IPC: F16C17/06
Filed: 1932-02-29
Abstract: 382,843. Tilting pad bearings. AKTIEBOLAGET NOMY, 2, Norrmalmstorg, Stockholm. Feb. 29, 1932, No. 6065. Convention date, March 6, 1931. [Class 12 (i).] In an axial thrust bearing having tiltably supported bearing-blocks which co-operate with a bearing-surface, the latter, at one or more places, is formed so that the blocks when moving past such places become unloaded. Each block 2, Figs. 1 to 3, has a radially extending rib which engages one or other edge a, b of a groove 8 formed in a carrier ring 3 fixed to the shaft (not shown). The blocks 2 are rotated by the engagement of abutment faces 6 or 6<1> on the ring 3 with projections 7 on the blocks 2. The distance between the faces 6, 6<1> is greater than the circumferential length of the blocks 2 so that the blocks can move slightly relatively to the ring 3 to permit them to tilt either on the edge a or edge b, according to the direction. of rotation, to form wedge-shaped lubricant films between the blocks and a bearing face 12 on a ring 11 seated spherically on a support 14. The ring 11 has one or more recesses 13, preferably two diametrically disposed, circumferentially longer than the blocks 2 so that as the latter move across such recesses they are relieved from load. The blocks are interconnected in pairs by projections 19 on rings 18 which are accommodated in dovetailed grooves 16, 17, in the blocks 2 and carrier 3 respectively. These rings 18 prevent the blocks from falling out during assembly and prevent the blocks from moving on to a wrong supporting surface a, b during operation. In a modification, the bearing face 12 of the ring 11 and the cooperating faces of the blocks. are spherical. As shown in Fig. 13, the blocks 2, as they pass across the unloaded zones 13, are engaged frictionally by spring-urged members 23 carried by the ring 11, to ensure movement of the blocks to the position of correct working upon reversal of rotation of the shaft. In this construction, the projections 19 on the rings 18 may be omitted. In another modification, the blocks 2, Figs. 14 and 15, have parallel ribs 28, 28<1> and are pivoted on pins 27 on the carrier ring 3, the extent of pivoting being limited by a rib 31 on the ring 3. The ring 3 has grooves 30, 30<1>, angularly arranged. When the shaft rotates in one direction, the rib 28 lies across the groove 30 and the block tilts thereabout so that the rib 28<1> enters the groove 30<1>, and upon rotation in the reverse direction the block turns about the pin 27 and tilts about the rib 28<1> and the rib 28 enters the groove 30. The ribs 28, 28<1> may be mutually inclined. The invention may be applied to bearings having stationary blocks 2.

IPC: C07C69/145
Filed: 1964-02-13
Abstract: Allyl acetate is prepared by contacting propylene with molecular oxygen in the presence of a palladium salt, acetic acid, the acetate of an alkali metal, alkaline earth metal or copper, and a copper salt, either under anhydrous conditions or in the presence of a quantity of water not exceeding 20% by wt., based on total weight of acetic acid and water, and maintaining the halide ion concentration at or less than 0.20 molar, the concentration of the acetate being at least 0.20 molar, both molarities being based on total volume of acetic acid and water,if present.  Preferred palladium salts are the acetate, chloride and bromide, and preferred acetates those of lithium, sodium and potassium.  The copper salt provides a redox system and may be cupric chloride or acetate. It is preferred to operate in the absence of added solvents, at 50-150 DEG  C. and under superatmospheric pressure.  In examples, isopropenyl and n-propenyl acetates are obtained as by-products.

[Class 92 (ii)] Relates to the remote pneumatic control of the firing, re-cocking and safety-locking devices of a number of automatic guns on aircraft as described and claimed in the parent Specification. According to the present invention, the valves controlling all the operations are arranged in a single casing 16 with (1) fingeroperated plates 18 which are provided with means for retaining them when moved into position for selecting the gun or guns to be fired by the device C3 on actuating the firing button 13 and (2) spring-returned plungers 26, in proximity to the selector plates, for operating the valves of the re-cocking device R3 of the gun selected for fire. Further, a plate 24 on the valve chest can be operated to control a camera P and a plunger 32 serves to operate a safety device S on the gun. The arrangement of pipe lines for the operation of devices on three guns is shown in Fig. 1, the air supply 11 to the firing devices being taken through the usual firing button 13 to a pipe 15, and that to the re-cocking and safety devices being taken directly from the supply pipe 11. Each of the valves 50, Fig. 7, is kept closed on its seat 52 by a spring 51 and is opened when a stem 54 is moved outwardly by a cam 44 on the extension 42 of the plate 18 or plunger 26. In the case of the extensions 42 of the selector plates, the stem engages a groove 61 to keep the plate down. The plungers of the re-cocking buttons 32 are returned by springs when pressure is released.
