Abstract: 1285157 Lawn mower skid assembly JACOBSEN MFG CO 21 April 1971 [15 May 1970] 10330/71 Heading A1F Two skid shoes 16, 17 of a lawn mower skid assembly are pivotally mounted on a bed knife 21 by means of clamps 18, bolts 19 and pivot rod 21. The shoes are inter-connected by means of a bar 23 which passes through member 27 which is welded on the shoe. The bar is an anti-scalping device and serves to transmit forces between the shoes 16, 17. Two standards 31, 32 through which bar 23 passes at their lower end at 28, each consist of member 33 and U-sharped member 34 which are screwed together by a screw 36. Screw 36 extends through a slot 41 which permits overall length adjustment of bars 33, 34 when screw 36 is loosened. A compression ring extends between the nut 29 and the bar 34 to urge the 'bar 34 onto the conical section 38 of bar 23. The upper end of bar 33 is provided with four openings 42 provided for receiving pin 43 extending between ears 44 welded to the mower tube 14. Pin 43 allows for further adjustment of the length of standards 31, 32. A U-shaped piece 47 secured to bar 33 by a screw 48 passing through slot 49 in piece 47 serves to indicate the mower elevation. Piece 47 can be slid up and down on bar 33 within the limits of the slot 49.

Filed: 1952-04-24
Abstract: 707,345. Raising derrick masts. DRESSER EQUIPMENT CO. April 24, 1952, No. 10365/52. Class 78 (4) A portable derrick rig has a mast pivotally connected to a mobile base for swinging movement between substantially horizontal and vertical positions by a multi-cylinder ram, one end section of which has a fluid pressure reaction surface cooperating with a surface on an intermediate section to form a confined pressure chamber with a restricted orifice to snub relative movement during extension, and restricted outlet means to snub the retraction movement of all the sections. The ends of the sections of the ram, Figs. 6, 6a, screw into a collar 44 fitted with a gland 45 contacting the smaller section and having a sleeve 46 wiping the cylinder wall, the sleeve having grooves 47. The ends of the two lowermost cylinders are open, the third cylinder has a bottom plate with an opening 51, the fourth cylinder has a cylinder member 52 at the bottom fitted with a fluid tight gland 53 and a series of holes 54. Liquid enters the ram through a passage 32 unseating the thimble of a valve 31 so that liquid flows through large slots 33 into the cylinders 26 to 28. The topmost cylinder is extended by the pressure of fluid against the surface 52 and fluid contained in the enclosed space escapes through holes 54 into the cylinder 29 and thence through the restricted openings 34, 38. To retract the ram the direction of the fluid flow is reversed, to retract the cylinder 29 first then the lowest cylinders are retracted by pressure of the mast, the liquid passing through restricted openings 34. The derrick 14 is pivoted to a beam 12 and supports 15 pivoted to the trailer frame. The ram 20 having sections 26 to 29 is pivoted to the frame and to the mast by ears 21 and 22. In the horizontal position the mast rests on a cradle 18 and in the vertical position it abuts a bumper 19. The cylinder is operated by fluid driven by a pump controlled by a four-way valve.

Abstract: 567,763. Drying coated or impregnated surfaces. NICHOLSON, J. C., and PLASTIC SPRAY, Ltd. June 28. 1943, No. 10441. [Class 34 (ii)] [Also in Group XI] Surfaces or surface materials coated and/or impregnated with plastic materials, including natural or synthetic rubber, are dried and/or cured by subjecting the materials to treatment by radiant heat from one or more gas-heated refractory or metallic elements, concurrently with treatment by a blowing or convection effect produced by the impingement or contact of the resultant hot products of combustion on said materials. The radiant heat may be applied by a portable burner comprising a metal box a which houses an elongated block b of refractory material formed with a number of bores c, each of the latter having located at its inner end a burner nozzle d and all the said nozzles d being supplied with gas from a mixing tube e provided with a gas inlet f and an air inlet g. The burner may be fitted with a handle h strapped to the mixing tube e, and deflector plates i are secured to the box a for directing the hot gases of combustion on to the material under treatment; the material may also be subjected to a supplementary air blast. If desired, instead of the burner being in the form of a hand tool to be traversed over the surface to be treated, one or more burners may be mounted or installed in a chamber or tunnel in which the material to be treated is located or through which it is progressively fed.

Abstract: 372,068. Indirectly - actuated valves. LAMSON PNEUMATIC TUBE CO., Ltd. and JACKSON, H. C., 132, Cheapside, London. April 9, 1931, No. 10532. [Class 135.] A rotary cylindrical valve 6 in a device for coupling a hose pipe connector 14 to the end of a pipe 7 in a vacuum cleaning installation is provided with means whereby the valve cannot be opened until the connector is inserted in the socket 3, and whereby the connector cannot be removed from the socket until the valve is closed. A pivoted catch 21 is actuated by the connector 14 to release the valve which is provided with a web 18 for turning it to the open position whilst the connector is retained by a flange 15 on the valve. A recess 17 in the flange coincides with the socket 3 when the valve is closed. The valve movement is limited by a pin and slot 16, 20. A hinged plate 10 closes the socket 3 when the connector is withdrawn. In a modification the valve is actuated by the connector which has a lug which passes along a groove 26, Fig. 5, in the socket into a recess 24 in the valve whereby the valve is opened, and the lug on the connector engaged behind the bush 25. A spring-pressed ball 29 engages a recess 31 to lock the valve in the open position.

Title: Processor controlled telecommunication switching system
IPC: H04Q3/545
Filed: 1973-03-06
Abstract: 1394158 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 6 March 1973 [6 March 1972] 10718/73 Heading H4K In a processor controlled switching system controlled by at least two processors using a common or duplicate stores storing first status words each indicating the state reached in setting up an associated connection, each processor is arranged upon occurrence of a breakdown in the other of executing a recovery programme which consists of addressing the locations of the first status words in succession, reading the call state as specified in each status word, releasing those calls which have not yet reached the connection stage and for each call in the connection stage to access from store an associated second status word which under normal operation would store the address of the first status word, to compare that address with the address used to access the first status word and in the case of non-identity to release the connection. The arrangement is generally similar to that described in Specification 1,181,184. The first status words are individually associated with corresponding originating junctors and store the identity of the processor handling the call; the connection state reached i.e. idle, dialling, ringing, connection effected and supervision (i.e. one party released but connection not yet released); and have a location for storing the relative address of the associated second status word. The second status words are associated with the terminating junctor circuit and from the moment when that junctor is taken into use store the identity of the processor involved, the type of call (not detailed) and the identity of the associated first status word. The address of the second status word is entered in the associated first status word at this time. The second status word is used to check that the defective processor was working normally when it set up that particular connection. If during the recovery propgramme a first status word indicates that the associated call is in the supervision state then that indication is changed back to the connection state to start again the timing of a period in which the party that has gone on-hook can again lift his receiver to reestablish the connection. The recovery programme is initiated by an external control unit storing that programme on magnetic tape. It may be initiated only when both processors become defective, it being noted that most processor breakdowns are of a temporary nature, the recovery programme being first fed to last processor to become defective and then to the other if it cannot be effected by that processor. A more extensive recovery programme is also provided in the tape unit if the first recovery programme cannot be effected.
