Title: Method and apparatus for the thermal working of material by radiant energy
IPC: H01J37/30
Filed: 1964-11-30
Abstract: 1,072,570. Welding by fusion; removing metal by electron and laser beams. K. H. STEIGERWALD. Nov. 30, 1964 [Dec. 2, 1963], No. 48546/64. Headings B3R and B3V. [Also in Division H1] In an electron beam or a laser beam material working process, e.g. for cutting, welding or treating materials, neutral atoms or ions of a material which will modify the process occurring at the working point are introduced into the beam. For instance magnesium or a mixture of magnesium and aluminium may be introduced to reduce surface tension in the zone of beam penetration, or carbon may be introduced to prevent the loss of carbides, or niobium may be introduced to prevent the formation of carbides. The material may be supplied in solid, liquid or gaseous form. In one embodiment powdered material is flung into the path of an electron beam from a motor driven fanlike device, shields preventing the spread of atoms except in the direction of the workpiece, Fig. 11 (not shown). In other embodiments the material may be introduced in the form of a wire with the electron beam directed obliquely on to the wire and deflected by a magnetic field to impinge vertically on to the workpiece. Fig. 2 (not shown), or the material may be introduced from an electrostatic spray gun at an intermediate focal point of the beam, Fig. 3 (not shown). Ions may be produced within a magnetic lens by means of a gaseous discharge between coaxial ring electrodes, one which functions as a hot cathode, Fig. 4 (not shown) or the material may be evaporated within the lens and an electronic discharge set up between an annular cathode and the housing containing the material, both within the lens structure, Fig. 5 (not shown). In this arrangement the lens polepieces are water-cooled. The ions may be separated out from the electron beam by a combination of magnetic deflecting fields to leave an electron beam containing only neutral particles, Fig. 6 (not shown). In a further embodiment the material in the form of a wire may be vaporized by a second electron beam independent of the working electron beam, Fig. 9 (not shown). Laser beams may also be used and in one embodiment, a combination of electron, ion laser and neutral particle beams is used, Fig. 7 (not shown). A laser beam may be used to vaporize material in the form of a wire fed into the beam through a hole in a plane mirror, the laser beam being reflected by the mirror on to the workpiece to perform the working operation, Fig. 8 (not shown).

Title: Rotary piston internal combustion engine
IPC: F02B53/08
Filed: 1974-11-08
Abstract: 1484165 Rotary positive-displacement machines KLOCKNER-HUMBOLDT-DEUTZ AG 8 Nov 1974 [14 Dec 1973] 48567/74 Heading F1F In a rotary engine comprising a multi-lobed rotary piston 1 or 2 defining working chambers 33 with a casing 6, 7, 10 or 8, 9, 11, at least one lobe is provided with a gas transfer duct 54 having openings 55 near the ends of the lobe for interconnecting adjacent working chambers 33 in order to extend the expansion and/or compression phase. The twin pistons 1, 2 are rotatable on the eccentric 3 of a shaft 4 between casing end members 6-9. Each chamber 33 has associated ports 41 and 42 in its casing end member 7 or 8, the ports 41 being connected through a conduit system 31, 37, 39 to an air inlet of a combustion chamber 30 and the ports 42 to a similar conduit system 32, 38, 40 connected to a high-pressure combustion gas outlet of the combustion chamber 30. The conduit systems are disposed in an annular chamber 25 between the end members 7, 8. The lobes of the rotors are of three types X, Y, Z (two of each); X having an air inlet passage 19, 17, 15 and an exhaust gas outlet passage 16, 18, 20; Y a passage 44, 45, 52 for the supply of compressed air to, and the return of combustion gas from the combustion chamber; and Z the transfer duct 54. Sealing strips 34 in the peripheral casing parts 10, 11 sealingly separate adjacent working chambers 33. Air enters the engine through intake pipes 48, 49 and flows through communicating feed pipes 50, 51 in the end members 6, 9. When each X lobe is expanding a working chamber 33 its inlet passage 19, 17, 15 aligns with a feed pipe 50 or 51 whereby air enters the working chamber. After the X lobe passes the next sealing strip 34 the suction phase ends and the air trapped in the working chamber is compressed by the following Y lobe. Compression continues until the passage 44, 45, 52 in the Y lobe communicates with one of the ports 41 to supply the compressed air to the combustion chamber 30. Soon after the working chamber 33 starts to expand again the passage 44, 45, 52 aligns with one of the ports 42 and thus receives hot combustion gases from the combustion chamber 30. After further expansion the Z lobe enters the working chamber whereby communication is established with its succeeding working chamber through the transfer duct 54. Exhaust commences when the exhaust port of the succeeding X lobe communicates with the working chamber. If the lobes enter a working chamber in the order X, Z, Y instead of X, Y, Z the air supplied to the combustion chamber is compressed first in two then one working chamber. In a modification gas enters and leaves the working chambers through valve controlled passages in the casing.

Abstract: 1,038,020. Air conditioning; heating and cooling buildings. SVENSKA FLAKTFABRIKEN A.B. Dec. 21, 1964, No. 51927/64. Headings F4V and F4U. In an induction type air conditioning system secondary air is treated in the heat exchangers mounted in the induction units before mixing with primary air and the liquid medium supplied to these heat exchangers is maintained at a temperature common for the whole plant and lower than the temperature of the secondary air, the temperature of the primary air being regulated in dependence on the outdoor conditions. In Fig. 4, 1 designates the heat exchangers within the induction units, 2 a heat exchanger forming part of the central air conditioning plant and 3 pipe lines forming a closed circuit between heat exchangers 1 and 2. 4 and 6 are circulation pumps, pump 6 maintaining through a by-pass line 7 a constant liquid flow through the heat exchanger 2 regardless of the number of heat exchangers 1 being used. During winter, heat is supplied by heated primary air, but in order to eliminate simultaneous cooling by the heat exchangers 1, the heated medium is passed to heat exchanger 2 through which the primary air 5 is taken in. In order to prevent moisture forming on heat exchangers 1 the medium is maintained at a temperature which is above the dew point temperature of the room air by introducing into the circuit a quantity of heated medium from a separate heat source at 8 and withdrawing a corresponding quantity of the medium at 9. In order to maintain, during fluctuations of outdoor air temperature, the medium at a desired temperature quantities of warm or cold medium are added to the circuit, the warm medium added as previously described and the cold medium added at 12 with a corresponding quantity discharged at 13. When the ventilating air 5 is too hot to cool the medium in heat exchanger 2, the medium is maintained at the desired temperature solely by the cold medium supplied at 12, circuit 3a, Fig. 5. If in this case, should the ventilating air also require cooling, a separate cold medium supply line 19 is used regulated by valve 20 which is governed by thermostat 22 located in the air flow 5, the cold medium passing straight to the heat exchanger 2 around circuit 3b. Any warm or cold medium added to the circuit is always added to the circuit immediately after the corresponding quantity has been withdrawn.

Abstract: 530,600. Calculating-apparatus. GUY'S CALCULATING MACHINES, Ltd., and HARRILD, L. G. G. June 28, 1939, No. 18836. [Class 106 (i)] A cam-disc and pin wheel machine having a barrel constructed in two sections with an interposed reversing mechanism is provided with a reverse shift mechanism which operates automatically, the shift being dependent upon the direction of the initial rotation of the product-forming section of the barrel after the multiplier register has been returned to zero by operation of the zeroizing handle. In the form shown in Fig. 1 the handle a drives the spindle d through a toothed wheel c co-operating with a reversing pawl. The barrel sections, d, g engage the product drums e and register drums h respectively. Loose on the spindle b and between the sections is a pair of bevel wheels i, j connected by a pinion k supported on a bracket l. To the spindle b is secured a sleeve m with a slot m<SP>1</SP>, Fig. 2, accommodating a pivoted key n having projecting ends that co-operate with oppositely disposed spiral rings il, j<SP>1</SP> on the sides of the bevel wheels. The key ends normally abut against radial slots, such as j 2, Fig. 4, in the spirals and on rotation of the spindle b the key is rocked in one or other direction to drive one or other bevel wheel, the spiral increasing the depth of engagement with the slot during the rotation. When the multiplier register h is zeroized by rotating a shaft s, Fig. 7, an arm r thereon raises a stirrup bar p<SP>2</SP> with arms p having projections p<SP>1</SP> which restore the displaced key n to its central position. This operation can only be effected when the barrel is in its normal position as a third arm with a tooth p<SP>3</SP> co-operates with a notched disc t on the barrel spindle. In a modification (not shown) the key n may be given a sliding movement instead of being rocked. The rings or cams would be formed with spiral faces in the direction of the axis and the sliding movement of the key would be controlled automatically thereby and manually through a collar and striking fork.
