Title: Arrangements for handling bulk load containers
IPC: B65G69/24
Filed: 1970-11-11
Abstract: 1338218 Loading and unloading bulk containers; roller conveyers J S SIEDER 9 Dec 1970 [10 Sept 1969] 44685/69 Headings B8E B8A and B8Q An arrangement for loading or unloading a bulk load container BC which is supported on pallet means PM on to or off a vehicle V comprises a vehicle bay VT for receiving the vehicle V, a dock area DK adjacent the vehicle bay VT, at least one slipper device B as described and claimed in Specification 1,316,267, and shown in Fig. 9, and a plurality of mobile skid devices C, D. If the floor of the vehicle V and the dock surface DK are not level a scissor-lift A is also used. Both the slipper device B and the scissorlift A have roller conveyers on their load-receiving surfaces. In use the scissor-lift A is moved along tracks T to align with the vehicle V and used to transfer a pair of the slipper devices B to the vehicle V where, in the deflated condition, i.e. with air bags 121 exhausted, they can be slid under a bulk container BC on their spring-loaded rollers 120. After raising, by inflation of the air bags 121, the bulk container BC can be run along rollers 122 on to rollers 120 on the scissor-lift A. The bulk container BC is then lifted so that with skid device D positioned adjacent the scissorlift A it can be slid on the rollers 120 to overlap the skid device D, whereupon it can be lowered so that its leading edge is supported thereby. The bulk container BC is then run, on the skid device D over the dock edge until the rear end can be supported on the skid device C, if necessary raising and lowering the scissor-lift A slightly to permit this. The skid devices C, D incorporate endless roller tracks and those of the latter are steerable. If the bulk container BC is to be stored on the dock area DK it may be transferred from the skid devices C, D to fixed stands E by the aid of jacks. Loading is the reverse of the above procedure.

Filed: 1975-10-30
Abstract: 1511178 Gaseous pressure systems MARTIN ENG CO 30 Oct 1975 [10 April 1975]  44963/75 Heading F1P In the apparatus shown, Fig.1, air from a source 28 is fed through a valve 30 and an aerator 20 into a reservoir 10. The air displaces a shuttle valve 54, Fig.2, which closes an orifice 48 in the reservoir 10 and an outlet 38 in the aerator, air passing into the reservoir 10 through a bore 58 in the valve. When the reservoir is fully charged the valve 30 is changed over to a "hold" position in which the valve is held closed by air trapped under it. In a "release" position the air-pressure forces the valve 54 away from the reservoir and air is rapidly discharged through the outlet 38.

[Also in Division G1] In a method of constructing a bellows, such as used for actuating a gas-lift valve (Fig. 1, not shown), located at the bottom of a well, a tube, having a wall formed with a plurality of alternately inwardly and outwardly facing rounded convolutions 19, 20, has an endless ring 22, having an inside diameter appropriately equal to the internal diameter to the tube across the inwardly facing convolutions 19, shrunk into contact with outwardly facing convolutions 20. The rings 22 are of a suitable fluorocarbon polymer, such as P.T.F.E. which will shrink a known amount when subject to heat. The tube and rings 22 are heated to about 600 to 700 F. to shrink the ring 22 into contact with outwardly open convolution 20. A pre-shrunk ring 21 is inserted into the tube, when the tube is heated so that the ring engages the inwardly facing convolution 19 when the tube cools. Asbestos rings 21a are provided at each end of the tube to prevent further shrinkage of the rings 21, 22 when the bellows is soldered into position on the gas-lift valve.

Abstract: 1,005,455. Hydraulic apparatus. BENDIX CORPORATION. Nov. 18, 1963 [Nov. 19, 1962], No. 45469/63. Heading F1P. [Also in Division B7] In an hydraulic system for a vehicle, a power steering mechanism 32 and a brake master cylinder 22 are supplied from an engine driven pump 10 through a flow dividing valve 15 arranged to direct the whole of the flow to the power steering system 32 when the pressure in a reservoir 16 connected to the supply for the master cylinder 22 reaches a predetermined value. Fluid supplied to the valve 15 through a conduit 14 and inlet port 38 passes around an annular groove 88 and through a passage 92 to pressurize a chamber 90 and displace a piston 84 against the pressure of a spring 114 and of fluid flowing from the chamber 90 through a restricted orifice 98 to a chamber 94. If the accumulator 16 is at low charge, the piston 84 assumes a balanced intermediate position wherein the annular groove 88 communicates through an annular chamber 46, a port 28 and a conduit 30 with the power steering mechanism 32, and the chamber 94 communicates through chamber 48, passage 116, a one-way valve 122, a passage 128 and a groove 56 with a chamber 44 connected to the reservoir 16 and having a port 18 supplying the master cylinder 22 through a conduit 20. When the accumulator pressure reaches the desired value a moveable wall 60 in the chamber 44 moves against a spring 58 to displace a plunger 62 and a pin 78, which unseats a ball valve 13 to open communication from the chamber 94 to the chamber 46 through a perforated cage 130 and a bore 102, and displaces the piston 84 to the right by means of a boss 80 to close communication from the chamber 94 to the chamber 48. Return conduits 26, 34, 40 connect a reservoir 24 integral with the master cylinder 22, the power steering system 32 and a port 36 from a leakage chamber 66 to a reservoir 12. The pump 10 may be of piston, vane or gear type. The system may be employed to supply aileron boost and landing gear retraction systems in an aircraft.

Abstract: 1,003,642. Digital computers. SPERRY RAND CORPORATION. Dec. 5, 1962 [Dec. 19, 1961], No. 45898/62. Heading G4A. A digital computer comprises a main memory and an auxiliary semi-permanent memory for storing a sub-routine which is rendered operative either manually or in response to an error signal produced by the computer. As described, the semi-permanent memory stores a " bootstrap routine," i.e. a series of instructions which when executed cause a programme or instruction to be transmitted from an external unit to the computer main memory, and which can be employed when loading the computer initially, or when an error has occurred, with a programme. The computer described (Fig. 1, not shown) is basically that disclosed in Specification 1,003,641 and is a 30-bit word singleaddress parallel-mode machine comprising a main ferrite core memory with conventional facilities for modifying instructions by the use of index registers; for conditional and unconditional jump instructions; for repeating instructions ; for shifting data; for multiplication and division; and for using double-length words. Blocks of data can be transferred between the computer and peripheral equipment as described in Specification 1,003,641. As shown in Fig. 2, the computer has a main memory 112 and an auxiliary semi-permanent memory comprising two sections 162, 164, each capable of storing eight 30-bit instruction words in the form of plugged connections (Fig. 3, not shown). Both the main memory 112 and the auxiliary memory 162, 164 employ the same memory communications register 124, the main memory and the auxiliary memory being alternatively effective under the control of a flipflop 128 which if set to its " 1 " state enables gates 136, 170 to cause the auxiliary memory to be effective. The flip-flop 128 may be set either by operation of a switch 144 to START position when loading the computer initially or during computer operation in response to a signal on a line 154 indicating a comuter error. When the flip-flop 128 is set, gates 118 in the output from the main memory 112 are inhibited and gates 170 in the output form the auxiliary memory 162, 164 are enabled, thus causing the execution of the " bootstrap routine " to load or re-load the main memory with the computer programme.
