Abstract: 958,550. Hydraulically propelled cranes. METROPOLITAN-CAMMELL CARRIAGE & WAGON CO. Ltd. Feb. 27, 1963 [March 2, 1962], No. 8183/62. Heading B7H. [Also in Division B8] A mobile crane has a single prime-mover 17, Fig. 1, which drives hydraulic pumps to supply fluid for driving the road wheels 15 of the crane in addition to rams and motors which luff and slew the jib and hoist the load. A winding drum 30 is driven by an hydraulic motor 29, Fig. 3, supplied with fluid by a variable output pump 19. The latter can give a low discharge at a high torque or a high discharge at low torque. Fluid from the pump 19 can alternatively be fed to the road wheel motors 35, 36 through valves 27, 33. The whole of the pump output may be directed to either or both motors 35, 36 thus giving a two speed gear. If the motors 35, 36 are of different capacity a three speed gear effect is produced. Valve 27 has a neutral position in which fluid circulates freely thus allowing the crane to be towed. Wheels 16 have hydraulically assisted steering, provided by a pump 57, a servo-unit 58, and a cylinder 60 connected to the track rods. The chassis is supported at two points on the axle 13 and a central point on the axle 14.

Title: Micro-programme having an overlay micro-instruction
IPC: G06F9/22
Filed: 1973-02-20
Abstract: 1391412 Micro-programmed processors BURROUGHS CORP 20 Feb 1973 [8 March 1972] 8204/72 Heading G4A Micro-instructions are transferred from a main memory 10 (Fig. 1) into a micro-string memory 28 when an appropriate "transfer" instruction is read out from the memory 28. As described, when sequence counter 37 is in its "idle" state and a micro instruction read from memory 28 into register 30 is recognized by decoder 35 as an instruction to transfer micro instructions from memory 10, at a starting address specified by section FA of register 24, the field length being held in section FL of memory 28 at an address specified by the contents of register 18 a signal OL is generated. Consequently AND gate 39 is enabled to (1) open gate 43 to transfer the current micro instruction address in register 32 to the top of a stack memory 34 and (2) step the sequency counter to its "initial" state. This results in gates 95, 45 being enabled to (1) transfer via gates 67, 33 33 the address in register 18 to address register 32, (2) set memory 10 to its "read" state and (3) step the sequence counter to its "source" state. Gate 53 is then enabled to (1) read a 16 bit micro instruction from memory 10 via gates 97, 51 to register 18, (2) increment by 16 the starting address and decrement by 16 the stored length in register 24 and (3) set counter 37 to its "sink" state. This results in gate 65 being enabled to (1) condition memory 28 to read, (2) transfer the contents of register 18 via gate 67, 69 to the memory 28, (3) increment the address register 32 and (4) reset the counter 37 via gate 98 to its "source" state. This process is repeated until either the field length becomes zero or the address in register 32 exceeds the highest possible address in memory 28. The sequence counter 37 is then set, by the enabling of gate 77, to its "exit" state so that the stored address in memory 34 is returned to address register 32 and register 30 is forced to its zero state by the output of circuit 88. This results in the output OL of decoder 35 being removed and the memory 28 being conditioned to read under the control of the address in register 32.

Title: Glow discharge tube for signalling purposes
IPC: H01J17/00
Filed: 1934-03-15
Abstract: 426,899. Discharge lamps. BARON, H., 231, Strand, London.-(Telephonwerke Albisrieden Akt.-Ges.; Albisrieden, Zurich, Switzerland) March 15, 1934, No. 8226. [Class 39 (i)] Discharge lamps for signalling have the cathode surface 4 on which the glow forms so inclined that extraneous light falling on the cathode is reflected on to the internally or externally blackened sides of the envelope 1. The cathode is conical with an apex angle of 90‹ or less and the anode 5 ring - shaped with an aperture equal to or less than the section at the anode 5 of the double cone on which the cathode 4 lies so that all light passing downwards through the anode falls on the blackened envelope and is not reflected upwards out of the lamp. Signalling with the lamp in sunlight is thus facilitated. The upper side of the cathode may be coated with electro-positive material such as potassium, sodium, rubidium, caesium, barium or strontium. The tube is filled with neon and argon, 3-30 per cent of helium being added to neutralize wall charges. To facilitate starting, a point 8 on the anode 5 approaches the cathode. To reduce instability due to the photo-electric action of extraneous light, a filter absorbing short wavelengths but passing the long wavelengths emitted by the lamp is placed in front of the tube. The wall of the tube may form the filter or may be coated with a varnish &c. The anode lead 6 passes through the cathode and is screened by a glass tube 7.

Title: Process for the preparation of bitumen emulsions
IPC: C08K5/098
Filed: 1953-03-26
Abstract: A bitumen emulsion of the oil-in-water type is prepared by incorporating in a bitumen a minor proportion (e.g. 0.5-10 per cent. by weight) of alkali metal or ammonium soaps of naphthenic acids having an average molecular weight above 250 (preferably 300-750), incorporating in water a minor proportion (e.g. 0.5-10 per cent. by weight) of one or more water-dispersible soaps, and emulsifying the bitumen in the water.  The residue obtained by distilling a petroleum lubricating oil fraction in the presence of caustic alkali may be used as the source of the naphthenic acid soaps.  Soaps for addition to the water may be the same naphthenic acid soaps which are added to the bitumen or may be residues obtained by the distillation of gas oil or kerosene fractions in the presence of caustic alkali; also suitable are the ammonium or alkali metal soaps of lauric, myristic, palmitic, oleic, ricinoleic, linoleic, linolenic and abietic acids, of the fatty acids derived from tall oil, coconut oil, palm kernel oil, corn oil, cottonseed oil, sardine oil, soybean oil, and peanut oil, of acids produced by the oxidation of petroleum or paraffin wax, and of sulphonic acids and acid sulphate esters.  The viscosity of the emulsion is controlled by adjusting the amount of naphthenic acid soap in the bitumen, and the demulsibility characteristics by varying the amount of soap in the water.

Abstract: 667,518. Load-handling machines. CALDWELL, F. April 11, 1950. No. 8849/50. Class 78 (iii). A load-handling device for gathering and subsequently dumping material comprises a bucket 10 which is hauled up a pair of tracks 5, 6 supported by pairs of brackets 7, 8 on a vehicle 1 by cables 14 of a winch 18. The bucket has rollers 11, 12 on each side which run respectively on the upper surface of the tracks 5, 6 and within channels formed in these tracks. When the empty bucket is hauled from its lowest position, Fig. 1, adjacent a pile of the material to be handled, it is first forced into the material so as to become charged and then drawn upwards along the tracks 5, 6. On reaching the top of the tracks, the rollers 12 contact rollers 33 on levers 31, pivoted at 32 so as to compress springs 35 on rods 34 connected to these levers until the bucket reaches the position 13. The bucket then contacts a buffer bar 21 extending between a pair of levers 20 pivotally mounted on the tracks 5, 6 so as to pivot these levers and tension springs 22. Eventually the bucket reaches its discharge position D, the levers 20 then abutting a fixed buffer bar 36. After the material has been discharged from the bucket 10, the winch driving means 2 is de-clutched from the shaft 3 supporting the winch barrels 18, and the levers 20 then, through the springs 22, operate to start the bucket on its return movement up over the ends 19 of the tracks 5, 6. When the bucket reaches its position B, the levers 31 through the springs 35 move the bucket on to the inclined portion of the tracks 5, 6 down which it returns by gravity to its lowermost position.
