Patent GB-629284-A (GB)
Title: Improvements in alternating current control apparatus particularly for arc welding
IPC: B23K9/10
Filed: 1944-08-28
Abstract: 629,284. Automatic voltage regulation. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 28, 1944, No. 16258. Convention date, Aug. 28, 1943. [Class 38 (iv)] In an arc - welding arrangement, the voltage across the arcing electrodes 10, 12 is kept to a safe value both during welding and during idling. In the arrangement shown, the A.C: supply 16 is adapted to be applied through contacts 29 to the primary 20 of the welding transformer 15 by energization of a relay 19, a power-factor improving condenser 32 being simultaneously connected in a parallel circuit. The relay 19 and a second relay 18 are adapted to be energized from tappings on the secondary of a transformer 17 also fed from the supply 16. To provide the above-mentioned protection, a switch 47 is moved into its lower position. A voltage of 55 between tappings 38, 39 then energizes relay 18 through resistance 52, causing the closing of contacts 50. A small current passes through relay 19, but is insufficient to operate it, and a safe voltage of 35 between tappings 37, 38 is applied through lines 43, 45 to the open electrodes 10, 12. To start welding, the electrodes 10, 12 are shortcircuited, whereupon the 35 volts operate relay 19 to cause the energization of the welding transformer, and the relay 18 is held operated by the 90 volts between tappings 37, 39, which energize a circuit including the relay 18, the lines 45, 43 and the electrodes 10, 12. The welding transformer, which on open circuit would have a voltage of 75 (the applied volts), has normally a safe welding voltage of from 25 to 40 volts. Should this voltage rise unduly, then since it is vectorially in series with the voltage across relay 18, the voltage across the latter will drop, causing the relay 18 to move to the " off " position, thereby de-energizing relay 19 and the welding transformer. The relay 18 will also open when the electrodes 10, 12 are open-circuited at the end of a welding operation and, in both cases, after de-energizing the welding transformer, it will reclose under the influence of the 55 volts between tappings 38, 39 and re-establish the voltage of 35 across the open electrodes, as already explained. In a modification, Fig. 3 (not shown), the welding transformer is dispensed with and a reactance takes its place for stabilizing the arc.

Title: Piezoelectric ceramic compositions
IPC: C04B35/48
Filed: 1965-04-15
Abstract: <PICT:1066752/C1/1> A ferroelectric ceramic composition of perovskite crystal structure comprises the solid solutions defined by the polygonal area ABCDEF within the phase diagram shown, the composition including Pb(Mg 1/3 Nb\ba2/3 )O3 in a mola ratio varying from 0.010 to 0.875 combined in a binary or ternary system with PbZrO3 and/or PbTiO3.  The molar ratio of titanate does not exceed 0.813 and that of zirconate does not exceed 0.950.  To improve the piezoelectric potentialities of the compositions, they may include up to 3% by weight of Mn, Co, Ni, Fe, Cr in oxide form.  Compositions, in order of preference, lie within polygons GHINO, UKLM, PQRSTU and GHIKLNO. These are all near the morphotropic phase boundary 5, 21, 12, 33, 38. The compositions corresponding to all membered points are tabulated. The basic materials (oxides and hydroxides) are ball-milled, calcined at 850 DEG  C. for 2 hours, milled again and wet-moulded into discs. The discs are sintered at a temperature of about 1200 DEG  C. for 45 minutes.

Title: Bag tie dispenser
IPC: B31B1/90
Filed: 1972-04-10
Abstract: 1422779 Bags; cutting apparatus CANADIAN INDUSTRIES Ltd 21 March 1973 [10 April 1972] 16401/72 Headings B5D and B4B Bag ties are secured by adhesive adjacent the mouth of each bag as it is delivered from the bag-making machine. Bags of plastics material separated by lines of perforations are fed intermittently and a plastics strip 3 forming the tie is fed via a pawl and ratchet and a pair of feed rolls (8, 9). A gun 5 applies adhesive to the middle of each tie, the tie then being pressed by a wheel 6 against a bag 1 as it passes over a roller 1. The movable parts of the machine are operated by pneumatic piston and cylinder units which are synchronized by an electric control circuit operating valves and receiving an impulse from the bag-making machine. The movable blade 25 is reciprocated vertically by a piston and cylinder unit 36 and is also moved horizontally by a second piston and cylinder unit 39 which swings the blade 25 about a pivot 29. This horizontal movement improves the cutting action and reduces wear on the cutting edges.

Class 137 An air conditioning unit, for fitting, e.g. into a corner of a room, comprises a panel P which extends from the floor to the ceiling and co-operates with corner walls W, W 1 , to form a chamber C, a discharge nozzle N for primary air under pressure being mounted at the rear of a heat exchanger B to supply an upward flow of primary air which induces secondary room air to enter an opening in the panel, pass over the heat exchanger B and mix with the stream of primary air for discharge to the room space through an opening G at the top of the panel. Instead of providing an inlet opening as shown it may be cut away at the bottom of the panel. In a modification, Fig. 4, the heat exchanger B<SP>2</SP> is arranged behind the middle opening 2 of three openings 1, 2, 3 in a panel P<SP>1</SP>, and a discharge nozzle N<SP>1</SP>, adjacent the heat exchanger B<SP>2</SP>, is capable, by means of a valve, of directing primary air either upwardly, or downwardly, within the duct c. When the louvres of the bottom opening 1 are closed secondary air is induced through the opening 2 and over the battery B<SP>2</SP> for discharge with the primary air, through the upper opening 3. If it is not desired to heat, or cool, the air delivered to the room the louvres of the opening 1 are opened and the battery B<SP>2</SP> is by-passed by the rising air. By suitably positioning the louvres of the openings 1 and 3 and discharging air from the nozzle in a downwards direction air can be delivered to the room at floor level. The heat exchanger connected to hot, or chilled, pipes 4, 5, has a condensate drain 6.
