Title: Improved process and apparatus for cooling the pistons of internal combustion engines by the evaporation of liquid
IPC: F02F3/18
Filed: 1924-01-17
Abstract: 210,078. Brown, E. Jan. 19, 1923, [Convention date]. Motor-power plant.-The piston of a Diesel or other internal-combustion engine is cooled by the evaporation of a liquid admitted to the interior of the piston, excess liquid being ejected through a hollow piston extension. The liquid is preferably preheated, e.g. by the exhaust gases, and the vapour generated may be employed for power purposes, or condensed and returned to the piston. The liquid is admitted by a pipe 10, Fig. 1, which may be controlled by a cock, or by a valve operated by the movement of the piston, or as shown, by a valve 12 operated by cam gear. Alternatively, the liquid may be supplied to the piston through pipes. The piston extension 2 preferably discharges the liquid into a closed container 13, Fig. 5, the pressure in the container being above atmospheric. Liquid may be withdrawn from the vessel 13 by a pump and discharged into the piston through the pipe 10, liquid being supplied to the vessel 13 from an external source. Alternatively, liquid may be supplied to the cylinder jacket 24 by a pump 26 and discharged to the piston through the pipe 10. As shewn to the left of Fig. 5, the vessel 13 may be in open communication with the cylinder jacket, liquid being withdrawn from the latter by a pump 22 and discharged to the interior of the piston. In a double-acting engine the space in the piston is preferably continued into the piston rod. The vapour spaces of a plurality of pistons or engines may be inter-connected. The Specification as open to inspection under Sect. 91 (3) (a) states also that the vapour generated in the piston may drive a motor coupled to the internal-combustion engine, the motor being used also as a starting engine by supplying it from a special generator. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the working up of asphalts or substances consisting of or containing asphalt-like materials
IPC: C10G1/02
Filed: 1936-01-18
Abstract: <PICT:0469036/III/1> Oils are recovered from the asphaltic sludgy residues, obtained in the destructive hydrogenation or extraction of carbonaceous materials, by heating the residues in a rotating drum of the known type provided with partitions and filler bodies, e.g. metallic balls, bricks of various shapes, &c.  A grinding action of the filler bodies is obtained by rotating the inclined drum intermittently at high speeds and providing the partitions with " pick-up " members, the partitions being perforated to allow passage of the materials, but not the filler members.  A destructive hydrogenation residue comprising 60 per cent oils and asphaltic materials and 40 per cent solids is supplied continuously through an opening d into an inclined rotary drum a divided by a partition c into chambers provided respectively with brick and spherical filler bodies b.  Residual material is withdrawn from a chamber e by lifting shovels f and is carbonized in a dust burner k to provide hot gases which are passed through a heating jacket m.  Steam is passed through a pipe h in counter current and the vapours and gases are removed through an opening i.  The furnace is heated to 500--550 DEG  C., and is rotated about 14 times a minute, the speed of rotation being doubled at intervals.

Title: Improvements in or relating to machines for surfacing, planing or similarly operating on roads and like surfaces
Inventor: PARSONS ALASTAIR CHARLES
IPC: E01C23/088
Filed: 1952-01-24
Abstract: 715,498. Road making &c. machines. LIMMER & TRINIDAD LAKE ASPHALT CO., Ltd., and OLDING & CO., Ltd., J. Jan. 26, 1953 [Jan. 24, 1952], No. 1935/52. Class 107 A road making or repairing machine with rotating or osciilating power-driven tools, more especially of the kind disclosed in Specification 694,027, has the tools mounted for upward and downward movement and power-driven through load responsive elements adapted, with more than a predetermined driving load being transmitted to each particular tool, to raise the tool clear of the abnormal resistance. The tool assembly 12 is raised or lowered by a hydraulic ram 13 to which pressure fluid is selectively fed by a fourway valve 16 actuated through a lost-motion device 24 by a piston 23. The fluid for actuating the latter is controlled by a valve 20 by a switch 42 so arranged that an excess load on the clutch 32 causes the switch to close. The clutch (Fig. 3) comprises two driving shafts 27 one to each tool 12, and sleeve portions 29 are keyed thereto. Each sleeve 29 is provided with pockets 31 in which the spring detents 36 engage, thus allowing the main driving chain 34 to drive the worms through members 32. When the tools are overloaded, the detents 36 are urged out of the pockets against the action of the helical springs and displace the plates 37, each of which closes the relevant switch 42. When this happens, the valve 20 operates the control piston 23 to move valve 16 so that the ram 13 elevates the tool. The load being now reduced, switch 42 opens and reverses piston 23 but, owing to the lost motion device 24, the tools remain up till reset by hand. Specification 715,499 also is referred to.
Patent GB-937823-A (GB)
Title: Improvements in or relating to magnetic data stores
IPC: G11C7/02
Filed: 1960-01-19
Abstract: 937,823. Circuits employing bi-stable magnetic elements. BURROUGHS CORPORATION. Jan. 19, 1960 [Jan. 28, 1959], No. 1952/60. Class 40 (9). [Also in Group XIX] Each storage unit of a data store comprises a pair of thin magnetic film elements, the easy axis of magnetization of each element being inclined with respect to the associated conductors. As shown in Fig. 1, the individual storage units are formed by pairs of thin film elements such as 11, 13 and 12, 14 having easy axes of magnetization parallel to the broken line 19. When storing data, the remanent magnetizations of both film elements of a pair are in the same direction along the easy axes and in one or the other sense, depending on the data stored. A cleared storage unit on the other hand has its two remanent magnetizations in opposite directions along the respective easy axes. To record data in a selected unit, a signal characterized by one or the other polarity and of one-third the value necessary to influence the field of a thin film element is applied from a data source 102 to a selected conductor 22 or 23. At the same time a two-thirds value drive signal is applied from a read/write drive pulse source 101 to a selected conductor 20 or 21. As the selected drive conductor 20 or 21 extends through the associated pairs of film elements in opposite respects, the coincident data and drive signals set up, as soon as they terminate, a characteristic data storage state with both elements magnetized in the same direction. Other elements are not influenced as the conductor current values are insufficient by themselves to effect switching. To read out the data stored in film element pairs such as 11, 13 and 15, 17 a read pulse of opposite polarity to the drive signal and of sufficient amplitude to effect switching by itself is applied by the read/write pulse source 101 to a selected conductor 20. This causes domain rotation in opposite respects in the film elements of each pair, with the result that each storage unit has its two films polarised in opposite directions after the pulse terminates. Due to the rotational processes involved, both films of a pair induce voltages of the same polarity in a sense conductor 24 or 25 which is applied to a strobed data utilization device 103. A more extensive circuit is shown in Fig. 3 in which nickel-iron alloy films 111-118 and 141- 148 of approximately 2000 Angstrom units thick are deposited on glass bases 131, 132 with the associated conductors 120-125 supported by glass-based epoxy resin insulating board. In this arrangement spurious induction between the drive conductors 120, 121 and the sense conductors 124, 125 by way of the parallel portions of the data conductors 122, 123 is prevented by reversing the pattern of conductors 122 and 123 on base 132 with respect to base 131, and arranging conductors 124, 125 in the same sense on both bases so that induced voltage tend to neutralise. Specification 937,824 is referred to.
