Filed: 1970-10-08
Abstract: 1331760 Welding by pressure THERMATOOL CORP 8 Oct 1970 [23 Dec 1969] 47873/70 Heading B3R In welding two metal portions, the portions are advanced through a welding zone the portions being spaced apart upstream of the welding zone and being brought together thereat, high frequency current is caused to flow along paths in the portions to and from the welding zone, the portions which are heated by the current are enclosed in an imperfectly sealed cavity disposed wholly upstream of the welding zone and protective fluid is supplied to the cavity to escape as a jet towards the welding zone to envelop the weld zone in a controlled atmosphere comprising said protective fluid. A stainless steel strip 10, Fig. 1, 2 formed into open tubular shape is heated by high frequency current e.g. 200-500 KHz supplied to the strip edges by conductive blocks 19, 20 and is passed through rolls 12, 13 to bring the heated edges together at the welding zone 18. An outer ceramic shoe 28 with a wedge shaped end carrying nylon shims 31 is arranged between the rolls 12, 13 and has a bottom surface contoured to the shape of the tube against which it is resiliently urged. A recess 37 above the spaced apart strip edges is provided in the shoe 28 to which the tubes 38, 38<SP>1</SP> communicate. A mandrel 40 is disposed within the tube and carries on a pad 45 of elastomeric material an inner ceramic shoe 29 shaped to conform to the inner surface of the tube against which it is urged by the pad 45. The inner shoe has a recess 47 co-operating with recess 37 in the upper shoe to form a cavity. A gas such as argon, helium, a mixture of inert gases, one or more reducing gases, a welding flux in fluid, fluent powder or mist form is fed via the tube 38 into the cavity at 20-200 cu. ft. per hr. to escape into and around the apex of the V formed by the strip edges, a manometer being connected to tube 38<SP>1</SP>. In a modification a single turn induction coil surrounds the tube and the conductive blocks are omitted. In producing a welded I beam a central web 63, Fig. 8, is moved longitudinally and top and bottom flanges 61, 62 are brought into engagement with the web by rolls 65. High frequency current is supplied to the web and flanges by contacts such as those shown at 67, 68. Ceramic shoes 72, 73, 85, 86 form cavities about the heated portions to which protective fluid is supplied by tubes 79, 89, the fluid escaping as jets into the apex of the V's formed by the heated members. It is stated that similarly a fin may be welded to a tube or plate, plates or strips welded to form angle members and lap welds formed. Welds as described in Specification 1,314,705 may also be formed.

IPC: G06F3/12
Filed: 1974-11-11
Abstract: 1493135 Printing and displaying data MODICON CORP 11 Nov 1974 [19 Feb 1974] 48729/74 Heading G4H The invention relates to the printing or display of selected combinations of data stored in a memory 21, Fig. 1, with data received from an external source 33. The described embodiment is a programmable printer 19 incorporating the memory, but data could alternatively be fed to a C.R.T. or a LED or liquid crystal display.  Data (and commands) may be fed via interfaces (IF) 22, 26 (Figs. 3 and 4, not shown) to a print mechanism 42 from memory 21 or source 33 (here a programmable industrial controller) under the control of a microprocessor (MP) 20, Fig. 2 (not shown) incorporating a buffer 29. When external data 27 is to be printed, MP20 receives command signals 23 via IF22 by sequentially addressing lines 24. When a "LOAD BUFFER" command (92) is received, MP20 generates an address 25 which retrieves the data 27 from IF26 via lines 28. The data (in BCD or ASCII form) is decoded and stored in 29 until a full line (21 characters) has been accumulated or until a PRINT command (88) is received; information 30 received from IF22 is then processed to generate printer control signals 32, 34, 36 which are fed to interfaces 38, 46 (Figs. 8 and 7, not shown) connected to mechanism 42 and to indicators 55 and status lines 59 for the external device 33 (which could alternatively be lights, solenoids or relays). When stored data must be printed, MP20 receives a START FORM signal (31) and generates a signal 36 which is transmitted to device 33 as FORM BUSY (printer in a stored data mode) and BUSY (printer does not want external data) signals 57, 61. MP20 obtains the address of the desired stored data 60 via IF26 and causes a selector 64, Fig. 5 (not shown) to retrieve the data 70 from memory 21 and transmit it to IF26. Data 70 may include commands such as ESCAPE (request external data, remove signal 61), CARRIAGE RETURN (print before further data retrieval) and END OF FORM (terminate process, remove signals 57, 61). Print mechanism 42 comprises 21 hammers co-operating with a rotating drum 128, Fig. 18 to print a line of characters made up of bars 136-154, Fig. 17. Means are provided for printing in an inverted format (Fig. 16, not shown), for providing sync signals, paper positioning and drive information (Fig. 9, not shown), and for indicating whether the lid 186 is in place. Flow diagrams are provided to illustrate operation of the whole system and of the various printing operations (Figs. 12-14, not shown). Description is also provided with reference to Figs. 3-8 (not shown) of memory 21, selector 64 and the interfaces. In particular, memory 21 and MP20 include ultraviolet memory chips, MP20 includes a CPU co-operating with various interfaces and stores, and IF26 includes means for dealing with both A.C. and D.C. signals.

Title: Self-contained injection apparatus
Inventor: WAGNER WOLFGANG DR MED
IPC: A61M5/20
Filed: 1974-11-19
Abstract: 1494646 Injection apparatus W WAGNER 19 Nov 1974 49989/74 Heading A5R Injection apparatus comprises a housing 61 having a muzzle 60 into which the skin of a patient can be drawn by means of a partial vaccum produced in said muzzle, the skin being impaled on an injection needle 28 of a dosage unit 63, which needle under the action of a partial vacuum is drawn through a bore 62 communicating with the muzzle. The vacuum is produced by means of a gas flowing from cylinder 71 via valve 72 and venturi 82, the gas exiting from the housing through an aperture (87a not shown) and drawing air from within housing 61 through opening 87, the vacuum produced causing a valve 85 to open whereby the vacuum acts on the muzzle through bores 62 and 81. The dosage unit comprises a cylinder 3 within which is a piston 33 having a ram 36 received in a sleeve 89 screwed into a block 27 containing a flexible bag holding medicament and communicating with the needle 28. A flat spring 93 is connected to piston 33 and engages a ledge on block 27. When vacuum is applied to the unit via valve 85 and bores 62, 26 piston 33 is drawn downwardly within cylinder 3 and spring 93 causes block 27 to move downwardly thereby forcing needle 28 through bore 62. When block 27 reaches the bottom of cylinder 3 further movement of piston 33 causes spring 93 to engage a stop on the cylinder and snap away from the block 27 so that ram 36 bears via a plate 90 on the bag to dispense the contents thereof through the needle. Further evacuation of housing 61 opens valve 83 activating a pneumatic cylinder 64 to eject the spent dosage unit 63. The units 63 may be filled from a bulk supply container 74. In Fig. 3 the housing comprises a cavity walled cylinder, the cavity 103 of which is maintained under partial vacuum, and the needle 106 is mounted on a piston 33 maintained in raised position by pegs 98 connected by cords to pegs 97 engaging a lower piston 102 having a central aperture sealed by a piercable membrane, the piston 102 being placed against the patients skin in use of the apparatus. The pegs 97 are released by pushing inwardly pegs 98 thereby allowing piston 102 to rise pulling the patients skin with it. When pegs 98 are released they spring back to release piston 33 which descends and engages piston 102, the needle 106 piercing the patients skin. A hub 96 of the needle seats in correspondingly shaped depression in piston 102 thereby raising a port 107 in the hub into space 105 which contains medicament. Spring 95 acts to force the medicament through the needle.

Title: Motor vehicle suspensions
IPC: B60G17/052
Filed: 1966-11-10
Abstract: 1,092,470. Vehicle suspensions. FORD MOTOR CO. Ltd. Nov. 10, 1966 [Dec. 20, 1965], No. 50341/66. Heading B7D. [Also in Division F2] To correct changes of trim when a vehicle is being accelerated or braked, a suspension device comprising a flexible envelope which may incorporate a coil spring and is in constant communication with the engine intake manifold, is interposed between the vehicle rear axle and body. At the engine idling speed, the reduced pressure in the envelope and the spring force maintain the vehicle at the desired trim. When the throttle is opened, the consequent rise in pressure in the envelope acts with the spring to correct the tendency of the vehicle to "squat." Orifices of various sizes can be selectively positioned in a bleed line to the interior of the envelope or in its connection to the intake manifold to provide a counteracting force in accordance with the gear ratio. There may be two or more such units and the coil spring of the units may augment or replace the vehicle springs-which may be leaf springs. In the embodiment of Fig. 3, the unit comprises a first envelope 30 connected to the intake manifold through a conduit 31 and a second concentric envelope 22 connected to the manifold through a conduit 26. A valve 32 is included in the conduit 31 and has a port 33 open to atmosphere, the valve being controlled by links 35 dependant upon the suspension height. When the suspension height decreases, the valve is open to atmosphere and the unit expands to correct the trim. The valve may be manually controllable. In a further modification, Fig. 4, an hydropneumatic strut comprises an inner cylindrical member 36 telescoping within a cylindrical member 38 to which is connected a cylinder 40 containing a piston 52 connected by a rod 54 to another piston 50 in the cylinder 36. Flexible envelopes 42 and 44 are connected between the cylinders 38 and 40 and the member 36, the annular space between them being connected by a conduit 26 to the engine intake manifold. The space 60 between the pistons is supplied with pressurized fluid through a valve 64. The fluid also enters a space 62 through damping orifices 58. The space above the piston 52 is filled with a compressible gas. The valve 64 is actuated in response to changes of suspension height to vary the length of the strut and additional correction is applied by the pressure in the annulus 46 depending upon the pressure prevailing in the intake manifold. The orifices 58 damp the vibratory motion.

Abstract: 1,211,093. Automatic temperature control systems. HOLZER PATENT A.G. Nov.7, 1967 [Nov.11 1966; Jan.26, 1967], No.50608/67. Heading G3R. In a temperature control system for a hot plate or a mashing machine, the heater wire is utilized as a temperature sensor by measuring the current through it. A triac 8 controls a heater 6, the current through which is measured by the volt drop across a resistor 9, or a transformer (not shown), and a volt drop being passed through a diode D1 to a resistor R2 connected to one side of a differential amplifier T1, T2, which through a threshold amplifier T6, T7 switches off the triac at a determined temperature. Initially the switch off point is determined by a polentiometer R7, R8 through a diode D2. A NTC sensor R9 in contact with the heater casing connected to another differential amplifier T3, T4 takes over the control of T1, T2 through a diode D3 at another determined temperature, hence lowers the temperature at which the triac 8 is cut out. Superimposed on the input of amplifier T6, T7 are synchronizing pulses from a circuit W3, R19, D4, C1 which ensure that triac 8 is only switched on at a voltage of zero. In a modification Fig.9 (not shown) the triac 8 is switched on by a monostable multivibrator (T9, T10) a triac (t 1 ) Fig.2 (not shown) determined by a CR circuit (C4, R27) after switching off. In an alternative circuit Fig.10 (not shown) an estable multi-vibrator (T8, T9) ensures that the triac 8 is switched on at regular intervals (t2) Fig.3 (not shown). The arrangement may be controlled by a cooking or washing programme switch which may reduce the set temperature as the desired temperature is approached. The time intervals (t1, t2) may be short. Additional temperature sensors may be employed and the mean, or an extreme value compared with the datum. The resistance of the heater may be derived when the heater is switched off by means of an additional resistor (12) Fig.4 (not shown). The system is stated to have the advantage of switching off an immensed heater e.g. in a washing machine, should the heater became unimmensed.
