Title: Improvements in or relating to control systems for hoists
IPC: B66B1/12
Filed: 1943-12-23
Abstract: 573,884. Hoist controls. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 23, 1943, No. 21516. Convention date, Dec. 26, 1942. [Class 78 (v)] A control system for hoists having at least one motor-operated hoist drum, braking mechanisms for either holding the drum or releasing it, and a lever for releasing the brake, has a normally open brake lever switch 39, 40 that is closed only when the lever is actuated to release the brake. A directional contactor 10, 11 causes the operation of the motor M in a given direction, and back contact members 8, 9 connected in parallel to the brake lever switch are normally closed when the directional contactor is not actuated. A controller C having an off and a plurality of operating positions has switching means closed in the,off position to energize electromagnetic means 21 for stopping the motor M, said means being connected in series with the parallel circuit of the back contact members 8, 9, and lever switch 39, 40 whereby either must be closed to energize the means. The controller C has switching means 19 closed in the off position to energize the electromagnetic means 21 and has switching means for energizing the directional contactor 10, 11 to open its back contact members 8, 9 when in any one of its operating positions. The electromagnetic means 21 is thus de-energized unless the brake lever switch 39, 40 is closed when said controller is in its operating position. The electromagnetic motorstopping device comprises a time-limit, arrangement 7 whereby a switch 13 remains closed for a short time after the time-limit device becomes de-energized during any one of the operating positions of the controller C. The time-limit device 7 is in parallel with the back contact members 8, 9 and brake lever switch 39, 40 whereby said electromagnetic means remains energized temporarily even though both back contact members and brake lever switch are open. A clutch operated by handles 43, 46 connects each hoist drum 37, 38 to the motor M.

Abstract: 516,097. Packeting-machines. CHALMERS, J. W., HALL, C. T., and MOLINS MACHINE CO.,Ltd. July 20, 1938, No. 21558. [Class 94 (i)] A packing machine is provided with apparatus for placing a separating element between articles to be packed, the apparatus comprising a conveyer to move a batch of articles in a predetermined path, a folding-guide extending lengthwise of the movement of the batch and about which a blank for the separating element is folded, a device operating in timed relation with the conveyer to fold the blank, and means aligned with the guide to separate the batch into two parts which are moved by the conveyer on each side of the guide. The batch may consist of cigarettes, or of a number of block shaped articles, contained iin a single row or two or more superposed rows. A batch of twenty cigarettes in two superposed rows, for example, may be moved from beneath a hopper 2, Fig. 1, by one of a number of pushers 3 carried by a continuously-moving conveyer 4. A folding-guide 37 is supported above the bed 5 of the packing machine between side guides 36 between which the cigarettes are moved. Blanks a, Fig. 12, for providing separating elements b, Fig. 13, are stored flat in a magazine 7 and are fed singly by a reciprocating toothed feeder between moving belts 20 which deliver each blank above the folding-guide 37, as shown in Fig. 9. A grooved block 39, Fig. 10, which is supported above the guide 37, is moved downwards to fold the blank about the guide, and is then moved along the bed towards the oncoming batch of cigarettes to position the blank in a depression 164 with the leading edge of the blank beneath thin plates that guide the batch on to the blank. The.front edge of the guide separates the batch of cigarettes into two parts, and the movement of the. pusher 3 delivers the cigarettes on to the panels c, Fig. 13, of the blank on each side of the separator b. The blank then engages the separator and moves the batch and the blank to any desired position, for example on to a slide which is to be inserted in a shell. Foils or other wrapping material may be folded about the batch and the separator, or about the batch before the separator is applied.

Abstract: Organic phosphorus compounds containing at least one carbon-phosphorus bond are prepared by reacting in an inert atmosphere an organomagnesium chloride complex of formula RMgCl.nQ with a phosphorus halide of formula R1bR11cPX3-(b+c), wherein R, R1\h and R11 represent a substituted or unsubstituted aliphatic radical (other than a vinylic radical), a cycloaliphatic radical or an aralkyl radical which, when substituted, contains no reactive substituent, n is an indeterminate whole number of the order of 1 to 3, X is chlorine, bromine or iodine, b and c equal 0, 1 or 2 and b + c is not greater than 2.  Q is a substituted or unsubstituted cyclic ether containing 5 or 6 atoms in the ring of which atoms only one is oxygen, the rest being carbon with the exception that a substituted nitrogen atom may replace the carbon atom in the 4-position when the ring has 6 atoms, the ring containing not more than one double bond, and at least one carbon atom adjacent the oxygen atom being free of any substituents; any substituents are unreactive to the reaction mixture.  Products of the types RR1R11P, RR1PX and RPX2 may be formed singly or in mixtures.  Suitable substituents in the R groups include chloro and hydrocarbyloxy groups.  An inert solvent may be used, which may be excess Q.  Examples describe the preparation of triamylphosphorus, tributylphosphorus, tricyclopentylphosphorus, triallylphosphorus, tribenzylphosphorus, octyldichlorophosphorus, dioctylchlorophosphorus and dibutyloctylphosphorus.

Title: Improvements in distributors for fuel injection systems of multi-cylinder internal combustion engines
IPC: F02M41/04
Filed: 1950-09-08
Abstract: 698,258. Valves and valve gear. BOSCH GES., R. Sept. 8. 1950 [Oct. 1. 1948]. No. 22131/50. Class vi). [Also in Group XXVIII]. In a distributer for fuel distribution from a single fuel pump to the separate fuel injectors of a multi-cylinder internal-combustion engine, a distributer casing having an inlet adapted to receive fuel from a single injection pump and. having a plurality of outlets receives a distributer piston which. whilst being reciprocated in an axial direction is also oscillated about its axis in order to connect the inlet. successively to the outlets. A plunger 30 driven from the end of the cam shaft 16 operating the fuel pump executes a combined reciprocatory and oscillatory motion and serves to distribute the delivery of the fuel pump 18 from a passage 24 to the respective cylinders of a four-cylinder engine. As shown, Fig. 5, a crankpin 40 of the shaft 16 drives a yoke 42 which in turn co-operates with a fork 43 attached to the plunger 30. Figs. 6 to 11 show the passages in the plunger and its housing. The dotted line b in Fig. 7 shows the path of a point on the surface of the plunger. The fuel pump makes four delivery strokes per revolution. As shown the plunger 30 in addition to distributing the fuel acts as a pump which supplies fuel to the inlet of the fuel pump 18. Alternatively it may supply lubricant. It may supply fuel through a separate de-aerator or filter to the fuel pump. The casing 15 may be in two separate parts, one housing the fuel pump and one the distributer. It is stated that the sealing of the plunger is satisfactory and is influenced favourably by the tight fits which are permissible due to favourable lubrication afforded by the particular oscillatory movement of the plunger.

Abstract: 800,808. Brake control mechanism. COAL INDUSTRY (PATENTS), Ltd. July 26, 1955 [July 29, 1954], No. 22168/54. Class 103(1). A brake control gear, particularly for colliery winding mechanism, includes an element interposed between the brake applying means and the brake shoe or the like, so shaped that throughout the entire range of movement of the brake-applying means for a small given movement thereof, the force exerted at the brake shoe, or the like, is such that the relationship between the said movement and the said force is logarithmic or approximately logarithmic. As shown in Fig. 1, this characteristic is obtained by the use of an especially shaped cam 1, whereby movement of the lever 2 produces the required variation of the hydraulic pressure in cylinder 5. In a second arrangement, use is made of a small crank and connecting-rod interposed between the lever and piston. As shown in Fig. 3, in a third arrangement a Scotch link mechanism 3 is used.
