Title: An automatic handling device for work-pieces capable of giving them a lateral movement combined with two movements of rotation about two axes at right angles
IPC: B23Q7/04
Filed: 1957-06-20
Abstract: 845,303. Machine-tool details. REGIE NATIONALE DES USINES RENAULT. June 20, 1957 [July 27, 1956], No. 19453/57. Class 83 (3). [Also in Group XXX] Means for handling workpieces during manufacture comprises a work-carrier 45 slidably and pivotally-mounted in a vertical guide on a trolley 1, and work-holding jaws 60-63 slidably mounted on a rigid frame, 64, 65, 67, rotatable about a horizontal axis on the work - carrier. In operation, a cylinder block is brought to the position P1 where it operates a switch to start a motor 25 rotating a screw 27 engaging a nut 28, thus lowering the carrier 45. A cam 40 on a rod 42 pulled down by the carrier 45 actuates a switch 38 to stop the motor 25 and operates a jack 46 to move the jaws 60, 63, and 61, 62 through levers 48-51 to a workgripping-position determined by stops 67<SP>1</SP>. Recesses in rods 76, 77, attached to the levers 50, 51, then coincide with a roller 80, which moves to operate a switch to raise the carrier until a second cam 41 on the rod 42 operates a switch 39 to stop the motor 25 and start a motor 13. The motor 13 traverses the trolley 1 along rails 7 by a chain 15. During this movement, swivelling drag-rods 82, 83, attached one to the carrier 45 and the other, through gearing 89, 72, 71, 70, to the frame 64, 65, 67, cause rotation of the work-piece about a vertical and a horizontal axis, by 90 and 180 degrees respectively. When a cam 21 on the trolley engages a switch 23, the motor 13 is stopped and the motor 25 is started. The workpiece is then lowered and deposited on a support at the position P2. If any undue resistance to the lowering of the carrier 45 is encountered, the nut 28 moves relatively to the carrier against a spring 33, and moves a rod 35 to actuate a safety-switch 37.

Title: Improvements in and connected with asynchronous dynamo electric machines
IPC: H02K17/28
Filed: 1924-08-16
Abstract: 220,652. Neufeldt & Kuhnke. Aug. 17, 1923, [Convention date]. Alternating-current induction machines; dynamos and motors, cooling.-In an asynchronous polyphase machine of the type in which condensers are employed for improving the power factor, the condensers are connected to auxiliary windings located in the machine slots and inductively coupled with the working windings. Fig. 5 shows the invention applied to a three-phase machine having primary windings LI, auxiliary windings LII located in the same slots, and condensers C permanently connected to the auxiliary windings. Instead of the connections shown, the windings may be arranged in delta and the condensers in star. For cooling the condensers they may be placed in the path of an induced current of air entering the machine. In the arrangement shown in Fig. 6, a sheet-iron tank B containing the oilimmersed condensers E is located in an extension G on the casing. A subsidiary stream of air enters the machine through the extension G and thus cools the condensers. Specifications 10269/98 and 10270/98 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the application of the invention to single-phase machines; it is stated that if the voltage of the system is too high for the condensers, the connections of the lines and the condenser terminals are interchanged. This subject-matter does not appear in the Specification as accepted.

Title: Fountain pen with filling piston and a reserve ink chamber
IPC: B43K5/06
Filed: 1958-06-18
Abstract: 884,820. Reservoir pens. WAGNER VERWALTUNGS G.m.b.H., GUNTHER. June 18, 1958 [June 21, 1957], No. 19505/58. Class 146(3) In a piston-filling fountain pen having a main and reserve ink chambers, the reserve ink chamber consists of a hollow piston head and the front and rear walls thereof can be moved towards one another by movement of the piston rod. The pen barrel 3, Fig. 1, contains the main inkchamber 4 which is filled by means of a reciprocating piston 1. The piston I consists of a cylindrical member surrounded by packing elements 2 and having a front wall 5 apertured at 6, and a rear wall 11 rigidly secured to an actuating rod 10 and slidable inside the cylindrical member the inner wall of which it engages with packing elements 9, the friction between the elements 9 and the inner wall 8 of the cylindrical member being less than that between the elements 2 and the barrel. The space 7 between the front and rear walls of the piston constitutes the reserve ink chamber. When the chamber 4 is exhausted the wall 11 is advanced by means of the rod 10 until it abuts against the front wall 5 of the piston, thereby discharging the reserve ink from the space 7 into the chamber 4 through the hole 6. In order to refill the pen from this position the whole piston 1 can be advanced by means of the rod 10 until it abuts against the end of the chamber 4 adjacent to the writing point. The rod 10 is then retracted whereby first the wall 11 moves to the rear end of the piston 1, thus filling the chamber 7 with ink, and then the whole piston is returned to the Fig. 1 position, thus filling the chamber 4. In a modification, Fig. 2, the rear wall 19 of the piston is connected to the front wall 17 by flexible bellows which collapse when the wall 19 is advanced towards the wall 17.

Title: An improved ball screw jack
Inventor: MURCOTT ANDREW JAMES
IPC: B64C13/00
Filed: 1970-04-23
Abstract: 1283483 Screw jacks H M HOBSON Ltd 19 April 1971 [23 April 1970] 19599/70 Heading B8J [Also in Division F2] A ball screw jack for operating an aircraft flap comprises a body 10, 11, 12, a rotary input member 13 constrained against axial movement therein, a screw 15 and a recirculating ball nut 16 connected to the flap. The drive from member 13 is transmitted to the screw 15 through taper rollers 17 positioned by a collar 24 between angled faces 18, 19 on heads 20, 21 on the member 13 and the screw 15. A stiff preload spring in the form of a rod 22 is screwed at one end into the member 13 and at its other end carries a nut 23 rotatably mounted on the end of the screw 15. Under static conditions, as shown, a face 26 on the screw head 21 contacts body portion 11, torque caused by the load reacting on the body and movement being prevented in the ease of drive shaft failure, the rollers 17 being completely unloaded. When the member 13 starts to drive, with either a compressive load or a tensile load, since the drive from member 13 to screw 15 has a greater mechanical advantage than that from the screw 15 to the nut 16, the member 13 and the screw 15 will tend to separate. In the case of a tensile load, which is supported by the spring 22, the separation occurs at considerably less load than the compressive load causing separation. At a certain limit of separation screw head 21 contacts a face 25 on body portion 12 locking the member 13 and bringing the whole system to rest. The torque transmitted by the jack is thus limited, to different amounts, both with compressive and tensile loads.

Title: Electric contact springs
IPC: H01H11/04
Filed: 1977-05-10
Abstract: That part of the contact spring on which the contact element (2) is mounted is of shell-shaped construction, and the material thickness of the contact element (2) is reduced in such a manner that it is matched to the shell shape (3) of the contact spring. This is achieved by the contact-element blank being reduced along its circumference corresponding to the change in the shape of the spring. This measure makes it possible to reduce the costs for producing contact elements from noble metal, without limiting their life. <IMAGE>

Title: Process for the catalytic treatment of hydrocarbons
Inventor: HIRSCH JOEL HERMAN
IPC: C10G47/30
Filed: 1954-07-08
Abstract: <PICT:0762904/III/1> In process for the catalytic conversion of hydrocarbons in the presence of hydrogen at high temperatures and pressures abrasion of the valves in the apparatus used to expand the fluidized solids from high reaction pressure to the low pressure used in the regeneration system is reduced by regenerating the major part of the catalyst by destructive hydrogenation at the high pressure prevailing in the main reaction to convert carbonaceous deposits on the catalyst into useful hydrocarbons, and by regenerating only a small part of the catalyst by the usual treatment with oxygen containing gases at normal pressures the reduction in pressure on the catalysts passing to the regeneration system being effected gradually by passing the catalysts from the reactor to the regenerator through an extended conduit in which the density of the catalyst particles is adjusted by introduction of a gas e.g. steam, at high pressure.  The apparatus comprises pairs of reactors 2 to which the fresh charge e.g. heavy oil, made into a slurry with catalyst from hopper 8 in tank 6 and preheated in furnace 18, is supplied through conduits 26 mixed with hydrogen supplied through lines 30 and heater 18 and lines 30.  The velocity of the hydrocarbon-catalyst-hydrogen mixture in the reactor 2 is adjusted to give dense phase conditions, catalyst and reaction products being removed from the top of the reactors through tubes 34 to a separator hopper 36 where catalyst separated from the reaction products in cyclones is accumulated.  The reaction products pass through line 58 to a scrubber 60 where they are scrubbed to remove residual catalyst with a fraction condensed in the scrubber and recycled through lines 66, 68, and heat exchangers 32, 34 passing thence through line 74 and heat exchangers 76, 78 to separator 80 where the liquid hydrocarbons are separated and passed through line 84 to the usual recovery plant; the gases are passed through the usual absorber 88 and the purified hydrogen is recycled with fresh make up through line 94, 95 in part to heater 18 and in part to heater 42.  The base of the catalyst separator hopper 36 is formed into two legs 40, 100 the catalyst to be hydrogenated passing into leg 40 and that portion to be regenerated into leg 100.  In leg 40 the catalyst is treated with hydrogen heated in the furnace 42 and supplied through lines 44, 46, the hydrogenated catalyst falling through line 53 and valved legs 56 in which it is aerated by further supplies of hydrogen supplied through lines 51, 52 and finally passes into the conduits 26 in which it is recycled with the catalyst-hydrocarbon slurry to the reactors 2.  The catalyst collecting in leg 100 is supplied to the usual regenerator 108 through a long narrow conduit 106 in which the reduction of pressure from the high pressure reactor system to the low pressure regenerator is effected gradually by injecting controlled amounts of high pressure gases e.g. steam through line 105.
