Abstract: 1,250,356. Capacitor switching arrangements for A.C. networks. LICENTIA PATENTVERWALTUNGS G.m.b.H. 22 Nov., 1968 [24 Nov., 1967], No. 55508/68. Heading H2H. To reduce transient oscillations in an A.C. supply network when a capacitor C is switched in to provide reactive compensation for a previously-energized inductance L, the capacitor is connected through an anti-parallel arrangement of a diode D and controllable valve Th which is made conductive when the network voltage is at its peak value and the voltage across the valve has a value within a range which is greater than zero and less than a predetermined maximum value, the turning-on of the controllable valve being prevented if the voltage at the valve is higher than the predetermined value. The valve Th is controlled by a circuit comprising members St 1 , St 2 , R, M of which the member St 1  gives a switching command when energization of the inductance L causes a drop in the mains voltage U and the remaining members delay turn on of the valve Th until its voltage is within the desired range, a condition which corresponds to a time period about the peak network voltage opposed to the charge voltage across the capacitor C developed by the diode D, Fig. 2 (not shown). If the network reactance L NZ  or the capacitive reactance C NZ  are respectively low or high, an inductance #L may be added to the circuit of capacitor C to increase the permissible voltage range over which the valve Th may be turned on. A discharge resistor r may be connected in parallel with the capacitor to reduce the voltage of the latter and so bring the valve voltage within the desired range.

Abstract: 1,252,284. Air-heating stoves. SCHEU PRODUCTS CO. 7 Oct., 1968 [6 Oct., 1967], No. 47405/68. Headings F4S and F4T. In a portable forced air heater having a burner assembly 13, a blower unit comprising a motor 11 and blade 12, and a tubular member 14 mounted within a shell 10, air from the blower is passed through the annular passage formed between the shell 10 and the member 14, the blower also supplying primary and secondary air to the burner. The burner assembly 13 includes a burner Venturi 33 and a cup-shaped flame spreader back plate 34 in front of which is positioned a solid spreader plate 35. A gas nozzle assembly 40 housed in a control box 15 attached to the shell 10 supplies gas to the throat 42 of the Venturi 33, said gas being mixed with air from the blower unit at this point. The back plate 34 is provided with a plurality of holes through which secondary combustion air from the blower passes to complete combustion. A spark plug 45 is provided to ignite the gas/air mixture. A gas inlet 50 is coupled with a solenoid valve 51 which is connected into a control system which includes a flame sensor probe 81 to detect the presence of a flame. A switch assembly incorporating a pair of mercury switches (84, 85, Fig. 5) mounted in the control box 15 serves to shut off the gas supply and the igniting system if the heater is tilted beyond a predetermined limit. A high temperature limit switch 88 serves to shut off the heater in the ease of overheating. In a modified embodiment liquid gas may be used: in this case a vaporizer loop is included in the fuel supply line. Control circuit for burner.-An igniter control 77 includes a resistive heater 99 coupled in series with a relay coil 100. The heater 99 operates a safety switch 101 after a predetermined delay. The relay coil 100 operates a switch 102 which is coupled with a solenoid 103 of the gas valve 51. A holding resistance 104 is coupled across the switch 102 and has a value high enough not to allow operation of the solenoid valve unless the switch 102 is closed.

A catalytic burner comprises a catalytic mass 16 situated between perforated inner and outer tubes 4, 6, the outer tube 6 being connected to an electrical source so as to act as a preheating resistance for taking the catalytic mass to the starting temperature of the catalytic reaction. The burner has a hollow base member 1 connected via an insulator 36 with a gas feeding tube 34 and containing a leaf spring 37 connected to the tube 34 and carrying a contact 38. A bimetal plate 27 acts on the leaf spring 37 and carries a valve 28 controlling the flow of gas into the base 1, so that when the burner is cold the valve 28 is closed and the contact 38 is urged into contact with a further contact 39 connected to an electrical source. Current thus flows through the leaf spring 37, the tube 34, a dish 31 and the outer tube 6 to the base 1. When the burner is hot the bimetal plate 27 moves to open the valve 28 and allow the leaf spring 37 to separate the contacts 38, 39. The tube 34 may be of copper, the outer tube may be of expanded nickel-chrome, and the catalytic mass 16 may comprise asbestos flakes coated with catalyst.

Abstract: 1,257,203. Banding tool. HAYDEN-NILOS Ltd. 9 June, 1970 [11 June, 1969], No. 29628/69. Heading F2G.  A banding tool (Fig. 1) comprises a body 1, a buckle-engaging claw 2 at one end, and a handle 3 at the other end. A guide slot 11 extends from the buckle claw 2 towards the handle 3, and a cavity 13 at the end of slot 11  contains a first rotatable cam 14 and a lever 4, the first cam 14 and a second cam 22, rotatably mounted on the lever 4, being independently biased clockwise towards the buckle claw 2 and respectively engaging an extension 17 of one side of the slot and a corresponding surface 27 on the lever. A handle 5 is provided for rocking the lever and manually-operated means are included for overcoming the spring loading of the cams. As shown (Fig. 3) two springs 20, 25 are secured to the body at the handle end. Spring 25 is attached to a pin 24 on the second cam 22, whereas spring 20 is attached to one end of a link 19 engaging a similar pin 18 on the first cam 14 (Fig. 1). One end of the link 19 is adapted to engage pin 24 in such a way that the second cam 22 may move anticlockwise independently of the first cam 14, but is constrained to move anti-clockwise when the first cam 14 is moved anti-clockwise by abutment of lever 29 (pivoted to the body), on pin 18. In operation a band is inserted sideways into the slot 11, the lever 29 having been moved to release the cams from surfaces 17, 24. The buckle is engaged by the claw 2. After release of the lever 29, reciprocation of lever 4 causes tensioning of the band, the cams preventing movement leftwards relative to surfaces 17, 27 while allowing rightwards movement. When the band is tight the tool is rotated bodily so as to bend the band back over the buckle, the lever 28 (attached to lever 29) contacting the work and thereby releasing the cams so that the end of the band may be removed after severance by a cutter 8. Friction means, e.g. spring washers, are provided to allow the lever 27 to hold the cams against the springs, and the handles 3, 5 may be removable, the handle 5 being useable to operate the lever 28 and a lever (9) (Fig. 2, not shown) attached to the cutter 8. The buckle engaging claw 2 may have a plurality of prongs (10) (Fig. 2, not shown) to enable buckles of various different sizes to be engaged.

A gated circuit, according to which of its terminals are marked, can operate as a reversible binary counter or as a shift register. A reset pulse on 0 sets all flip-flops to zero. For forward counting LV is primed, while RL is marked for reverse counting. Counting requires a mark on lead LZ, shift a mark on SL. Potential on E together with a clock pulse CP reverses FF1. For forward counting gate I1 becomes 0 and II1 changes to 1, so priming both inputs of FF2. The second clock pulse restores FF1 and sets FF2 to 1, and so on. For reverse counting the gates I1-I3 always have an output 1 but the gates III1 &c. have output 0 whenever the related flip-flop is false, so priming the succeeding flip-flop. The modified circuit of Fig. 3 is arranged for binary-coded decimal operation with carry from NAND gate II/III4 accompanied by forward or reverse marking of the higher denomination from gate NV or NR, as the case may be. Shift.-The several count control leads except CP and E are disabled and shift prime lead SL marked. The required input is applied at SW and the gates IV, V for each flip-flop control gates I-III to shift the pattern along at each clock pulse.
