Abstract: 1,227,955. Cutting by fusion. UNION CARBIDE CANADA Ltd. 14 May, 1968 [6 June, 1967], No. 26015/67. Heading B3V. [Also in Divisions G2-G3] An identification mark in the form of a notch is formed in a ferrous metal plate 17 during a torch cutting operation by blowing a jet of oxygen at a point on the plate which has been preheated to cutting temperature by the torch 6. The movement of the torch 6 is controlled by a photo-cell copying device 1 scanning a tracing line 3, the reflected light being intercepted by a vibrating reed. An auxiliary photo-cell scanner 7 is mounted adjacent the scanner 1 for scanning markings 4. When markings 4 are sensed, a solenoid valve 8 is actuated to cause a jet of oxygen to be discharged from a nozzle 10 thereby forming a notch at the cut edge of the plate 17. The solenoid valve 8 or the control device for the torch 6 may be manually operated. The photo-cell assembly may be replaced by a system wherein the desired pattern 3 is imprinted on a magnetic tape. One or two torches may be positioned to produce bevel edge cuts (Figs. 4 and 5, not shown).

Abstract: 1,229,162. Valves. CARLO GAVAZZI S.p.A. 3 April, 1969 [3 April, 1968], No. 17440/69. Heading F2V. [Also in Division G3] A valve for regulating pressure, temperature or humidity in an air-conditioning system has a diaphragm 2 actuated by a fluid-pressure corresponding to the variable to be controlled and two valve plugs 13, 19 slidably mounted on a stem 8 to operate successively and add cold or hot water to the recycled water in the system, the plugs being separated by a piston 22. As the diaphragm moves the valve stem 8 downwardly, the plug 19 is moved by a spring 21 to open a port 23 and allow recycled water from an inlet 27 to be mixed with hot water from an inlet 25 flowing into an outlet 26. After there has been sufficient downward movement of the stem to interrupt the flow of hot water by closing a port 16, a ring 12 engages the plug 13 and opens a port 16 to allow cold water from an inlet 30 to be mixed with recycled water from an inlet 28 flowing into an outlet 26 until the downward movement has sufficiently compressed a spring 15 to close a port 24 for the recycled water. The stem 8 and port 16 are of stainless steel and the plugs of stainless steel or bronze with inserts 14 of neoprene or "Teflon" (Registered Trade Mark). A cap of hot-pressed light alloy encloses the diaphragm which may also be of neoprene.

Abstract: 1,229,808. Storage container. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. 29 March, 1968 [29 March, 1967], No. 15155/68. Heading B8C. A container having a base and three or more side walls extending from the base, is filled with rod-like objects, e.g. cigarettes, by introducing the objects into the container whilst the latter is inverted with the base uppermost and horizontal and providing means for preventing the objects from escaping from the container under gravity whilst the container is in the inverted position. In one embodiment, Fig. 7, an endless conveyer 55, carries cigarettes to a rotating wheel 26 having spring loaded blades 28 which are forced outwardly by cam 29 to engage and push the cigarettes up a shoot 27. The cigarettes enter the inverted open-topped container 9 by pushing blades 18 aside which fall back to prevent the cigarettes re-entering the shoot. Photo-cells 33 detect when the container is full whereupon the support 6 pivots about an axis 1 to deposit the container on an intermittently movable conveyer. A stop (21), Fig. 8 (not shown), disengages a spring loaded angle iron (25) to release the container from the support. The container touches a detector to cause the conveyer to advance and replace the filled container by an empty one. This contacts a switch to cause the support and angle iron to invert the new container ready for filling. In another embodiment, Fig. 1, cigarettes are fed along a shoot 27 to a reciprocating pusher 8 beneath the container support. When the filled container is pivoted a stop 44 prevents the support 6 from pivoting fully with the container. In further embodiments a lid may be fixed to the container. The container 9, Fig. 10, is tilted and emptied by a pusher 36 engaging a stop 35 to pivot a spring loaded lid so as to open it at its lowest side. In another embodiment a sliding lid, Fig. 19 (not shown), is opened by a rail (54) engaging a hook (57) and pulling against the bias of a spring (56). The lid, Fig. 21, may have two apertures 16a, 16b and an oscillating pusher 66 pushing cigarettes alternately through each aperture. In a further embodiment, Fig. 16 (not shown), full containers are emptied at a station (A) of a machine for processing the objects which are then fed to a filling station (B) which may incorporate any of the filling devices referred to above. In a still further embodiment, Fig. 24 (not shown), a pair of lids (6a), (6b) are operated alternately to place rows of objects into the container (9) from a conveyer 46.

Abstract: 1,251,519. Automatic regulation of electrolysis cells. COMPAGNIE PECHINEY. Nov. 4, 1968 [Nov.6, 1967], No.52073/68. Heading G3R. The position of the anode 52 of an electrolysis cell 5 is automatically regulated to maintain the electro-motive force e of the cell within a predetermined range. As shown the voltage U between the cell terminals 53, 54 is applied to a voltage converter 1 which produces an output kU at terminals 13, 14. A shunt 6 carrying the cell current I supplies a current converter 2 whose output k<SP>1</SP>I is fed to a potentiometer 3 which is adjusted to produce an output k<SP>1</SP>k<SP>11</SP>I equal to kRI, were R is a predetermined value adopted for the internal resistance of the cell. The outputs of members 1, 3 are combined to produce a difference voltage k (U-RI) which is applied to a relay 4 arranged to produce an output when (U-RI) is outside the range set by the limits (e+ a) and (e-a) where a is half the permissible deviation allowed for e. The output of relay 4 is a constant intensity impulse whose polarity is dependent on the direction of deviation of k (U-RI) and which is applied to a D.C. or single phase A.C. electric motor 55 controlling the position of the anode 52. The difference voltage k (U-RI) is also applied (1) to a relay 7 arranged to control the motor 55 when (U-RI) becomes smaller than (e-a<SP>1</SP>) where a<SP>1</SP> considerably exceeds a, the impulse from relay 7 being of greater power or longer duration than that from relay 4 to cause the anode 52 to rise quickly until (U-RI) is once more within the range; (2) to a relay 8 via a capacitor 85 which makes relay 8 responsive to rapid fluctuations of k (U-RI), the action of relay 8 being similar to that of relay 7; (3) to a relay 9 which disconnects members 4, 55 if k (U-RI) varies suddenly and is reduced to a value smaller than k (e-a<SP>11</SP>) where a<SP>11</SP> is greater than a<SP>1</SP>, the regulating action being interrupted for this condition. Switches may be provided to allow the system comprising members 1--4, 7--9 to regulate a number of cells, all using the same reference value R. Separate potentiometer may be provided if a different value is used for each cell. An additional potentiometer may be added to the circuit of converter 1, Fig. 3 (not shown) to minimize the number of switches needed. The operation of the regulating system of the invention in compared with that of a known system measuring a pseudo-resistance of the cell, Fig.2 (not shown).

Abstract: 1315092 VTOL aircraft D R PENDER 28 Jan 1971 3421/71 Heading B7W A VTOL aircraft 15 is enabled to take off and land tail uppermost by the provision of a lift rotor 24 whose blades 25 are collapsible and rotatable about a mast 27 which is pivoted about an axis 28 during vertical flight so that the rotor can be stowed away in a fuselage compartment 29 while the aircraft flies horizontally. The aircraft is a modified conventional fixed wing aircraft propelled, e.g. by jet engines. Take off is effected by rotating blades 24 by means of tip jets 26 to lift the tail end of the aircraft; as it is lifted from the ground the aircraft pivots relative to 28 until it is suspended vertically (Fig. 4). Conversion to horizontal flight is effected by elevating the aircraft to a height sufficient to permit it to fall and then to level out of a dive as rotor 24 folds and retracts: the aircraft is then controlled by conventional means. The reverse process is employed to effect landing. Rotor 24 is equipped with cyclic and collective pitch controls for directional flight and for blade pitch variation when the aircraft is vertically suspended. During inclined flight the pilots compartment remains horizontal and the passengers rest on their backs in seats 23.

A switching circuit comprising two transistors 22, 24 is placed across the resistor 15 and when no voltage is developed across the resistor, transistor 24 is rendered non-conducting owing to a bias applied by a battery 17, while transistor 22 is rendered conducting by a negative potential applied to its base via the R-C circuit 23, 25 thereby shorting out a counter 16 connected in the emitter-collector circuit of the transistor 22. Upon a voltage being developed across the resistor 15, a negative potential is developed at the base of transistor 24 rendering it conductive and transistor 22 non-conductive, since the base current ceases to flow, a voltage pulse substantially equal to the voltage of the battery 17 being applied to the counter 17, a timer, not shown, being connected to the counter to give a frequency reading. A very small voltage across resistor 15 is sufficient to operate the circuit and thus a generally square waveform is applied to the counter 16.

Abstract: 1323293 Stripping cables PLESSEY CO Ltd 30 Nov 1970 [24 Dec 1969] 62826/69 Heading H2C  A length of cable insulation is removed by severing the insulation by blades circumferentially at two spaced points and also lengthwise, blade deflecting means being provided to facilitate removal of the insulation. In the embodiment shown, two identical heads 10 are moved together about wire 24. Each has blades, e.g. 12, 13 for the left hand head, with circumferential cutting edges 17 and a blade, e.g. 11 with a longitudinal edge 18. After the heads close on the wire a member 21 is moved upwardly by actuating rod 23. The member 21 has inclined ends which act through balls 22 to flex the blades 12, 13 outwardly to separate the outer parts of insulation from the intermediate part. The member 21 then pushes blade 11 upwardly to split the intermediate part which is meanwhile gripped by pressure pads (25), (26), (Fig. 3b not shown), above and below. After retraction of the heads the insulation fragments are removed (e.g. by compressed air). In another embodiment, Figs. 6-9, not shown, the blades 11, 11<SP>1</SP> are replaced by bars which press the intermediate portion of insulation to distort it so that it can be severed by a vertically acting blade. The severed portion is then removed by feeding the wire forward in a curved path.
